Before Installation Ver. 2.0 Cable Path Inspection When installing a cable that connects between the rectifier, Main Ground Bar (MGB), and backhaul device, etc. within the system, the cable path length and the cable installation method, etc. must be inspected. Follow these guidelines when inspecting the cabling path. A minimum cable length must be selected provided that it does not affect the cable installation and maintenance. The cable must be placed in a location where it will not be damaged by external factors. (Power line, flooding, footpaths, etc.) In areas where the cable can be damaged by external factors, ensure that measures are taken to prevent damages to the cable. (Cable tray, ducts, flexible pipe, etc.) Cable Cutting Measure the exact distance, carefully checking the route, and cut the cable using a cutting tool. Follow these guidelines when cutting the cable. Cut the cable to the length determined in the Cable Path Inspection step. Use a dedicated cable cutting tool. Cut the cable at right angles. Be careful to keep the cable away from any moisture, iron, lead, dust or other foreign material when cutting. Remove any foreign material attached to the cable using solvent and a brush. Cable Installation Cable installation involves running the cable along the cabling path to the target connector of the system or an auxiliary device after cable path inspection and cable cutting have been completed. Follow these guidelines when installing a cable. Be careful not to damage the cable. Run the cable so that it is not tangled. In particular, when installing a cable from a If the cable is damaged, cut out the damaged section before installing. horizontal section to a vertical section, be careful not to reverse the upper and lower lines of the cable. Always use the maximum curvature radius possible, and make sure that the minimum curvature radius specification is complied with. If the cable needs to be protected, use a PVC channel, spiral sleeve, flexible pipe, and cable rack, etc. 1-8 SAMSUNG Electronics Co., Ltd. 2600-00F46VGAA Ver. 2.0 Smart MBS RRH-P4A Installation Manual Table 1.2 Allowed Mnimum Cable Bend Radius No Type 1 GV/CV/FR-8 2 Optic Cable 3 UTP/FTP/S-FTP Cable 4 1/2 in.

* If the allowed cable bend radius is specified by the manufacturer, comply with the bend radius specified. Cable Binding Cable binding involves fixing and arranging an installed cable using binding strings, cable ties, binding lines, and ram clamps, etc. Follow these guidelines when binding a cable. Be careful not to damage the cable during binding. Use appropriate cable binding tools according to the target location (indoor or outdoor, etc.) and the use of the cable (power supply cable, optical cable, feeder line, etc.). Do not let the cutting section of a cable tie and binding line, etc. be exposed to the outside. This may cause damage to cables or personal injury. Make sure that the cutting sections of cables are not exposed to the outside. Trim the binding string so that you have about 1.97 in. (5 cm) of string left from the knot. And insert the remaining string into the knot and make sure the knot does not loosen. If there is a potential danger of contact failure in a connector connection due to tension, install the cable in the shortest distance. SAMSUNG Electronics Co., Ltd. 1-9 2600-00F46VGAA CHAPTER 1. Before Installation Ver. 2.0 Connector Attachment Connector attachment involves assembling a connector to an installed cable or to a device on the site. Follow these guidelines when attaching a connector. Make sure you are fully aware of the connector assembly method before assembling a connector. Assemble the connector in accordance with its pin map. Each connector has a hook to prevent its core positions from being changed. Use a heat shrink tube at a connector connection for cables that are installed outdoor, such as feeder lines, to prevent water leakage and corrosion from occurring at the part exposed to the outside. Connect each cable of the connector assembly in a straight line. Be careful when connecting a cable not to trigger contact failure at a connector connection due to tension. Identification Tag Attachment Identification tag attachment involves attaching a marker cable tie, nameplate, and label, etc. to the both ends of a cable (connections to a connector) to identify its use and cabling path. Marker Cable Tie On the marker cable tie, a label can be attached. The appearance and specification may differ depending on the type and manufacturer Follow these guidelines when attaching an identification tag. When installing a cable outdoor, use relief engraving and coated labels, etc. to prevent markings from being erased. Since the form and attachment method for identification tags are different for each provider, consult with the provider before attaching them. Connecting Ground Cable In cabling, the connection of cables without the connection to the ground cable may cause the damage of the equipment or the bodily injury of the worker. Connect the ground cable first. 1-10 SAMSUNG Electronics Co., Ltd. 2600-00F46VGAA Ver. 2.0 Smart MBS RRH-P4A Installation Manual Cable Installation Checklist When installing, take care not to overlap or tangle the cables; also, consider future expansion.

Installation of RRH-P4A Ver. 2.0 2.9 Installation Test If the installation of the system is complete, progress the installation test to check the status of the system. The purpose of this test is to remove problems, which may generate after the service starts, in advance for stable operation of the system. If there is any problem, restore the system and write out the failure table. The installation test should be progressed in the order of power section test and function test. Power Section Test The power section test is progressed as follows:

1) Execute the off of the breaker (RRH-P4A power in the DU cabinet is connected). Make sure that the DC resistance between the -48 V/RTN is over tens of kilo ohm (k). and RRH-

2) Make sure that the DC resistance between the RTN of Terminal block-

P4A frame is no greater than 10 . The ground cable must be installed at DU cabinet and RRH-P4A 3) Execute the on of the breaker (RRH-P4A power in the DU cabinet is connected). Make sure that the voltage between the RTN of terminal block-

, is over -40 VDC. 4) Execute the on of the breaker (RRH-P4A power in the DU cabinet is connected). Verify that the LED (Red or green) in the RRH-P4A optic window is lit. 5) Turn off the breaker in the DU cabinet which is connected to the power of the RRH-

P4A. 6) Fasten the cover fixing screw (T20) using a Torque 0.87 lbf.ft (12.0 kgf.cm). Close the power window cover and the optic window cover. Caution When Opening and Closing Power Window Cover Make sure to turn off the breaker connected to the RRH-P4A power before opening or closing the power window cover of the RRH-P4A. If you open or close the power window cover when the breaker is turned on, it may cause damage to the system, or cause an electric short circuit resulting in severe injury. Caution on Rain-proof Gasket Damage When Installing Window Cover Be careful so as not to let the rain-proof gasket get damaged (broken or incorrectly positioned). Check whether the rain-proof gasket is damaged before closing the power window cover and the optic window cover. IF the rain-proof gasket is damaged, replace the system (RRH-P4A) with a new one. 2-68 SAMSUNG Electronics Co., Ltd. 2600-00F46VGAA Ver. 2.0 Smart MBS RRH-P4A Installation Manual RTN

Sector Antenna Installation A.1 Cautions when Installing a Sector Antenna Precautions of antenna installation are as follows. Sector antennas should be installed vertically. (1) Antenna is the precise material, so be careful not to make damage or form change. When moving antenna, use the tool suitable to rating. In addition, use the rated carrying device which is at least 200 % or more than antenna considering the stability. If it rains, suspend connecting the feeder cable and antenna. Be careful not to give too much strength to the antenna. Fix it after adjusting the direction of antenna exactly. Distance between steel tower and antenna and the distance between send-receive antennas are based on the antenna layout. Attach the antenna on the position specified in the drawing. Install the antenna not to make a feature change of the antenna considering the direction of the radiation When connect the connector to the antenna, not making the alien substance flowed and is not under the influence of PIMD. Measure VSWR of all antennas and the value should be within the regulated value. A.2 Sector Antenna Layout The method of sector antenna layout is as follows. 1) Use the transit to adjust the antenna installation direction exactly. 2) Fix the direction of the sector antenna, same as the angle settled when designing the cell after installing the steel tower. 3) Arrange the antennas of each sector to the sector directional angle at right angles by adjusting the distance between antenna and steel tower. In the event of the station whose the direction between sectors is not 120, install it to make the steel tower and antenna direction different being careful of the tilt and azimuth. 4) For circular platform, separate the antenna interval at maximum. SAMSUNG Electronics Co., Ltd. A-1 2600-00F46VGAA ANNEX A. Sector Antenna Installation Ver. 2.0 A.3 Sector Antenna Installation The method of sector antenna installation is as follows. 1) Put up an antenna pole and insert the sector antenna into the antenna pole using a fixing clamp. 2) Set the antennas up/down tilt to 0 and fix the fixing clamps at the top and bottom. 3) After tightening the fixing clamp, adjust the antenna up/down (tilt) depending on the signal strength. The bolt of the guide clamp must be loosened, so the antenna angle can be adjusted. 4) After setting the antenna angle, fasten the bolt of the guide clamp, which was loosened previously. Regarding the nut, the double nut mounting should be used to prevent the nut from coming loose.

Smart MBS Abstract 2.1 Smart MBS System Description Smart MBS is the Basestation of Samsung Multi-Modal System. It is managed by packet core (either BSC, ACR, or EPC), and makes call to terminal to create CDMA/WiMAX/LTE links. Smart MBS interfaces with UE via either CDMA(3GPP2 CDMA2000 1X Advanced and 1xEV-DO Rev.0/Rev.A (20110408)), WiMAX (IEEE 802.16) or or LTE(3GPP LTE Rel.8/9). It provides broadband high speed data service and multimedia services. In order to implement this, Smart MBS can perform Modulation/Demodulation (for voice or packet traffic), assign Scheduling and Wireless Bandwidth (for efficient use of RF resources and to guarantee QoS), handle ARQ(Automatic Repeat request), perform ranging feature, provide connection control feature (for sending Smart MBS information and enable/maintain/disable the call), Synchronize BSC/ACR/EPC, provides Power Control, and executes system operation management.

Depending on Frequency bandwidth and duplexing type, RRH can be classified into following types. SAMSUNG Electronics Co., Ltd. 2-1 Smart MBS Abstract

- RRH-C2: 800MHz Cellular band, 2Tx/2Rx RF path

- RRH-P4 : 1.9GHz PCS band, 4Tx/4Rx RF path

- RRH-B4 : 2.5GHz BRS band, 4Tx/4Rx RF path Smart MBS has other features provided as below. Common Platform DU/RRH Digital boards of each wireless technology, to be mounted in Smart MBS, share the common DU platform. Therefore, different boards(for multiple technology) may be mounted in a single DU, and operator can mount up to 4 DU in outdoor DU cabinet to implement various configuration. RRH of Smart MBS can simultaneously support multiple technologies in the same duplexing type with the same bandwidth. RRH(Remote Radio Head) separated from DU(Digital Unit) In order to provide ease of installation and various network structure, Smart MBS has separated RRH from DU. Between RRH and DU, a fiber optic Baseband I/Q and C&M interface, based on CPRI(Common Public Radio Interface), is used to send/receive data traffic signal and OAM data. DU and RRH gets -48VDC from rectifier inside the outdoor DU cabinet. Provide Easy Installation RRH integrates optic-sync component and RF signal processor, and is a small & light weight single module. RRH can be mounted onto Walls, Poles, or Stands. In addition, distance between RRH and Antenna is minimized that RF signal loss(caused by Feeder Line) is decreased. Therefore, it can provide improved RF performance when compared to Basestation that has Digital Unit and RF Unit altogether. Natural Cooling Mechanism RRH(Remote Radio Head) may be installed in outdoor environment, and its thermal-dynamic design efficiently dissipates heat without requirement of additional cooling mechanism. Also, no maintenance cost is required for RRH cooling. Feature for Loop-Back Test of the line between DU and RRH In order to check functionality of the Base-band I/Q and OAM interface between DU and RRH, Smart MBS provides Loop-back Test. Provides Remote Firmware Downloading RRH may be replaced with firmware to enhance service and upgrade new features. At this time, Site visit is not required as firmware can be downloaded from basestation operation server (such as BSM/WSM/LSM-R). Therefore, operator can minimize the site visit, reduce the maintenance cost, and easily operate the system. Provides Monitoring Port. Through debug port of RRH, operator can monitor the information about the unit. 2-2 SAMSUNG Electronics Co., Ltd. Smart MBS System Description Support for Smooth Migration Smart MBS can provide migration from CDMA to 4G(WiMAX or LTE )wireless telecommunication by either adding traffic processor card and channel card or software upgrade. In case of RRH, in the same frequency band, simple Software upgrade would allow conversion into 4G wireless telecommunication. Also, simultaneous operation of 3G and 4G is possible. Furthermore, following are the Smart MBS features per each wireless technology. 2.1.1 Smart MBS CDMA System Feature Support for 1X Advanced In order to improve voice capacity and data rate, Smart MBS supports 1X Advanced. In case of 1X Advanced, EVRC-B, RLIC, QOF, New RC, QLIC, and MRD are implemented for voice capacity enhancement. QChat Smart MBS supports QChat(Qualcomm Chat) which is a PTT service that is based on 1xEV-DO. For QChat service, BSC/BTS runs in conjunction with QAS(QChat Application Server) and PDSN to exchange signaling and bearer traffic with terminal. QChat can support 1:1 call and group call, and reserve QoS(Quality of Service). Provides Dual Band Dual band is a feature that allows single basestation to provide different services in 2 different RF bandwidths. Smart MBS can simultaneously provide service on 800MHz band and 1.9GHz band. With exception of RRH, Smart MBS can utilize entire hardware to be shared for 2 bands. Smart MBSs Digital Unit can provide up to maximum capacity of 12 Carrier/3 Sector(2Br) or 6Carrier/3Sector(4Br). For 1.9GHz, Smart MBS supports 4Br. Tx/RX Diversity Support In order to improve RRH-C2 and RRH-P4, Smart MBS optionally provides TDTD(Time Delay Transmit Diversity) feature that will transmit CDMA Modem output of 1Tx from RF path of 2Tx. Also, in order to improve receive performance, RRH-C2 and RRH-P4 provides 2 Branch receive diversity (which provides 2 receive path per each sector) as a standard. Optionally, Operator may choose that RRH-P4 can provide 4 Branch receive Diversity which will provide 4 receive paths. 2.1.3 Smart MBS LTE System Feature OFDMA/SC-FDMA Technology Smart MBS can handle downlink OFDMA/uplink SC-FDMA channel processing that supports the Physical Layer of LTE standard. Downlink OFDMA can use sub-carrier, which are assigned to each subscriber, to simultaneously send SAMSUNG Electronics Co., Ltd. 2-3 Smart MBS Abstract data to multiple users. Also, in accordance with the requested data transfer rate, it can assign single(or multiple) sub-carrier to particular subscriber for data transmission. Also, when entire sub-carriers are shared by multiple subscribers, OFDMA can dynamically determine well-matched sub-carrier for each subscriber, so that resource can be assigned efficiently to enhance data throughput. Uplink SC-FDMA is basically similar to Mod/Demodulation algorithm of OFDMA. However, DFT process is handled per each subscriber during Tx Modulation, then on contrary, IDFT process is handled during Demodulation to minimize potential PAPR that can occur during the transmission. Also it is responsible for assigning the particular frequency resource to particular subscriber continuously. As a result, it will reduce the power that is dissipated by terminal. Support for Broadband Channel Bandwidth Smart MBS provides wide bandwidth of up to 20MHz and high speed/high capacity packet service. Support for MIMO Smart MBS uses multi antenna to support 2x2 or 4x4 MIMO. MIMO has following algorithms SFBC (Space Frequency Block Coding)-Downlink Increases Link Reliability, This technology implements STBC(Space Time Block Coding) on frequency domain rather than time domain. a) 2 Tx Case : STBC(Alamouti codes) algorithm is used. b) 4 Tx Case : SFBC and FSTD(Frequency Switched Transmit Diversity) are used together. SM (Spatial Multiplexing)-Downlink This algorithm sends different data to different antenna path to increase peak data rate. (each path uses same time/frequency resource) a) SU(Single User)-MIMO: This is the SM between Basestation and single UE. It increases the peak data rate of a single UE. b) Open-loop SM: If channel changes often, or channel information is not available because UE travels in high speed, this is the SM algorithm that works without PMI(Precoding Matrix Indicator) feedback. c) Closed-loop SM: If channel information is available because UE travels in low speed, this is the SM algorithm(codebook-based precoding) that works after receiving UEs PMI(Precoding Matrix Indicator) feedback from basestation. UL Transmit Antenna Selection-Uplink This is the algorithm (Closed-loop selection of Tx antenna) that indicates terminal to use 1 RF chain, 2 Tx antenna, and which antenna to use. MU(Multi-User) MIMO or Collaborative MIMO-Uplink There is no increase in peak data rate, but this algorithm increases the total cell throughput. This is SM algorithm in which 2 terminals use the same time/frequency resource for UL, where basestation use single Tx antenna, and two orthogonal terminals are used. 2-4 SAMSUNG Electronics Co., Ltd.

Modulation/Demodulation Smart MBS encodes the downlink packet which was received from upper system, and modulates it. On the other hand, Smart MBS demodulates uplink packet which was received from UE, then decodes it. RF Scheduler Smart MBS provides RF scheduling feature in order to efficiently distribute systems RF resource, and to guarantee system quality. Call Admission Control(CAC)/ Burst Operation Control(BOC)/ Overload control feature is provided in case of 1X, but Proportional Fair/ Round Robin/ QoS Scheduler is provided in case of DO. Power Control 2-6 SAMSUNG Electronics Co., Ltd. Smart MBS System Description In order to maximize the system capacity, smart MBS should control the terminals power so that minimal signal to noise ratio is obtained for each terminal. Throughout such power control, Smart MBS can minimize the noise, provide good voice quality, and provide increased system capacity. 2.2.1.2 LTE Processing Feature Downlink Reference Signal Generation and Transmission Reference Signal is used for demodulation of downlink signal at UE, and also utilized for measuring the channel characteristic for scheduling, link adaptation, and handoff. In case of sending Non-MBSFN, there are two reference signals, namely cell-specific reference signal and UE-specific reference signal Cell-specific reference signal is used for Channel Quality Measurement, MIMO Rank Calculation, MIMO precoding matrix selection, and signal threshold for handoff. For MIMO, different reference signal is sent per each antenna path. Downlink Synchronization Signal Generation and Transmission Synchronization signal is used by UE when obtaining the initial synchronization before communicating with basestation. It has two signals, namely Primary Synchronization Signal(PSS) and Secondary Synchronization Signal(SSS). Cell identity information can be identified by synchronization signal. UE can obtain additional information(other than cell information) via Broadcast Channel. Synchronization signal and Broadcast channel are transmitted through the exact center of channel bandwidth of the cell, which is 1.08 MHz band. This is to allow UE to identify cells basic information(such as cell ID) regardless of basestations transmission bandwidth range. Channel Encoding / Decoding Smart MBS executes channel encoding/decoding function which is designed to correct the error generated on wireless channel environment. LTE uses turbo coding and 1/3 tail-biting convolutional coding. Turbo coding is generally used to send relatively large data of downlink/uplink, while convolutional coding is used for control data transmission(downlink and uplink) or used as broadcast channel. Modulation/Demodulation In case of downlink, Smart MBS receive data from upper layer, process it with baseband (of physical layer), and sends it out onto wireless channel. At this time, baseband signal is modulated to higher bandwidth in order to transmit it to longer distance. Also, in case of uplink, basestation receives the data via wireless channel, demodulate it into baseband signal, and decodes it. Resource Allocation & Scheduling With LTE, Smart MBS uses multi link scheme. OFDMA is used for downlink while SC-FDMA is used for uplink. Both schemes allocate 2-dimensional(time & frequency) resources into multiple terminals(without overlapping to each other) that communication link is allocated to multiple terminals. In exceptional case of MU-MIMO mode, same resource can be shared among multiple terminals. Such allocation of resources onto multiple terminal, is referred to as scheduling, and individual scheduler of each cell can process this. LTE Scheduler of Smart MBS can analyze channel environment of each terminal, demanded data transfer SAMSUNG Electronics Co., Ltd. 2-7 Smart MBS Abstract rate, and various QoS to optimize the resource allocation to maximize the cells total throughput. Also, in order to reduce the interference with other cells, it can exchange information with other cells scheduler via X2 Interface. Link Adaptation Wireless channel condition can change either rapidly or slowly, either improve or deteriorate. When channels condition can be expected, it can be used to increase the data transfer rate, or maximize the entire cells throughput. This is called Link Adaption. Particularly, MCS(Modulation and Coding Scheme) can adjust modulation scheme and channel coding rate at different channels conditions. For example, good channel environment will utilize high-order modulation(such as 64 QAM) to enlarge the number of transmitted bit per unit symbol, but bad channel environment will utilize low-order modulation and low coding rate to minimize the channel error. In channel environment where MIMO is supported, MIMO Mode is utilized to either increase the users peak data rate or cell throughput. In cases when channel condition is incorrectly reported, or if higher ordered modulation or coding rate is used, error can occur. This can be efficiently corrected by Hybrid-

ARQ feature. Hybrid-ARQ (H-ARQ) H-ARQ is a physical layer retransmission scheme which utilizes stop-and-wait protocol. Smart MBS executes H-ARQ to minimize the potential impact due to change in either wireless channel environment or noise signal level. It improves throughput by retranmitting or combining the frame in physical layer. incremental redundancy(IR), and considers chase LTE uses H-ARQ combining(CC) scheme as one specific method of IR. In case of Downlink, Smart MBS uses asynchronous scheme, but uplink uses synchronous scheme. technique based on Power Control The purpose of power control is to adjust the power level to transmit particular data rate. Excessive power would cause interference while insufficient power would increase error rate that either retransmission or delay is created. When compared to the CDMA, power control is not as important in LTE. However, appropriate power control can improve the LTE systems performance. In case of LTE uplink, SC-FDMA does NOT create near-far problem as in CDMA. However, high power level from nearby cell can still deteriorate the uplink performance. Therefore, UE should transmit with appropriate power level to prevent it from radiating interference to nearby cells. In case of LTE uplink, UEs power level may be adjusted to lower inter-cell interference level. In case of Downlink, Smart MBS can transmit with appropriate power depending on terminals location and MCS so that inter-cell interference can be minimized. As a result total cell throughput can be improved. MIMO In order to provide high performance data service, Smart MBS supports various types of MIMO through multi Antenna(2Tx/2Rx or 4Tx/4Rx) of RRH as described in above section 2.2.3 2-8 SAMSUNG Electronics Co., Ltd. Smart MBS System Description 2.2.2 Call Processing Feature 2.2.2.1 CDMA Processing Feature Call Process and RF Resource Allocation Feature Smart MBS allows UE to connect to, or disconnect from the network. When UE is either connected or disconnected from the network, Smart MBS communicates with UE using 3GPP2 1X/1xEV-DO interface, or communicates with BSC using Samsung proprietary standard interface, to exchange signaling messages required for call processing. Execution of Handoff Smart MBS provides feature to process signaling (required for softer hand-off between sectors, and soft/hard handoff between basestations) and bearer. Softer handoff is performed between different sectors of the same basestation. Also, handoffs between basestations are performed in conjunction with BSC. CAC (Call Admission Control) Feature In order to maintain efficient use of RF resources and high performance service, Smart MBS provides feature for mobile terminal or basestation to accept/deny the demand for wireless resource allocation. Also, to accept particular RF resource demand, it may modify the characteristics of different wireless resources. 2.2.2.3 LTE Processing Feature Cell Data Transmission Feature Smart MBS should periodically send MIB(Master Information Block) and SIBs(System Information Blocks) within the cell region, that the UE (which received this information) will be able to execute appropriate call processes. Call Control and Wireless Resource Allocation Feature Smart MBS allows UE to either connect to, or disconnect from the network. Via Uu interface (for UE) or S1 interface (for EPC), Smart MBS exchanges signaling messages required for call processing at UEs network entry or release. Smart MBS should execute the call control and resource allocation that is necessary for UE during network entry. Then, at network release, it should collect the previously assigned resource, and release it. Execution of Handover (HO) Smart MBS can support intra frequency, inter-frequency, or intra-eNB cell HO, X2 HO between eNB, S1 HO between eNB, and executes signaling and bearer processing feature required for HO. HO related messages are transmitted via following interfaces : Intra-eNB HO via interface inside eNB, X2 HO via X2 interface, and S1 HO via S1 interface. At X2 and S1 HO, Smart MBS executes data forwarding feature in order to minimize the traffic interruption. Source eNB provides 2 schemes i) of direct forwarding using X2 interface, or ii) of indirect SAMSUNG Electronics Co., Ltd. 2-9 Smart MBS Abstract forwarding using S1 interface, to forward to target eNB. Via Data forwarding, smart MBS should make sure that UE receives the traffic without interruption during the HO. AC(Admission Control) Feature For Bearer Setup request from EPC, Smart MBS should provide the admission control(based on QoS) that system is not overloaded. Capacity and QoS based admission control is executed as follows. Admission control based on capacity This contains the threshold for the maximum number of UE (new call/handover call) and the maximum number of bearer. When the requested call is accepted, number of UE and number of Bearer will need to be compared to the threshold before the acceptance is confirmed. Admission control based on QoS In accordance with the estimated PRB usage of newly requested bearer, PRB usage statistics of the bearers in service, and maximum capacity of PRB(per bearer type, per QCI type, UL/DL ), Smart MBS determines the call acceptance. RLC ARQ Feature Smart MBS can execute ARQ feature only for RLC AM(acknowledged mode). At packet data exchange, RLC should divide the SDU into RLC PDU unit, before sending it. Depending on the received ARQ feedback data, RLC should retransmit the packet to improve the reliability of data communication. QoS Support Feature Smart MBS should receive QCI(QoS Class Identifier) which defines QoS characteristics, GBR, MBR, AMBR(Aggregated Maximum Bit Rate) from EPC. Also, it should provide QoS between wireless interface between UE and eNB, and on the backhaul between the eNB and S-GW. Wireless interface should perform retransmission in order to satisfy rate control based on GBR/MBR/AMBR values, bearer priority defined in QCI, and scheduling considered packet delay budget, and PLER(Packet Loss Error Rate). For QoS in Backhaul, Packet classification(QCI based), QCI to DSCP mapping, and marking should be executed. Queuing should be provided in accordance with the result of the mapping, and each Queues should send the packets to EPC per strict priority. In case of EMS, other than the previously defined QCI, configuration for operator specific QCI and QCI-

to-DSCP mapping can be configured. 2.2.3 IP Processing Feature IP QoS Feature Smart MBS should support DiffServ(Differentiated Services) that backhaul QoS can be provided when communicating with control stations such as BSC/ ACR/EPC. Smart MBS can support Diffserv of 8 class, and also can support the mapping between user traffic service class and DiffServ Service class. In addition, Smart MBS can support the mapping between DSCP (Differentiated Services Code Point) and 802.3 Ethernet MAC service. 2-10 SAMSUNG Electronics Co., Ltd. Smart MBS System Description IP Routing Feature Since Smart MBS provides multiple Ethernet interfaces, it stores the IP packets routing information(what Ethernet interface to use) into routing table. Smart MBSs Routing table is enabled by operators configuration, its configuration method is similar to routers standard configuration method. Smart MBS only supports static routing, and it does not provide routing feature for traffics received from external network. Ethernet/VLAN Interface Feature Smart MBS provides Ethernet interface, and supports static link grouping feature, VLAN(Virtual Local Area Network) feature, and Ethernet CoS feature in accordance with IEEE 802.3ad. At this time, MAC bridge feature(IEEE 802.1D) is omitted. Smart MBS can configure multiple VLAN ID on single Ethernet interface. In order to support Ethernet CoS, DSCP value and CoS value(of Ethernet header) is mapped on Tx packet. 2.2.4 Convenient Operation and Maintenance Feature In conjunction with management system, Smart MBS executes System initialization and reset, system configuration management, operation parameter management, system resource and service alarm/status management, statistics management for system resource and various performance data, diagnostic management for system resources and services, and system access and security management. Graphic and Text based Interface Samsung Multi-Modal System has management server as BSM/WSM/LSM which utilizes DBMS(Database Management System) to manage CDMA access system, WiMAX system, and LTE system. Smart MBS is managed with such operational servers. Operational servers provide graphic and text based interface for intuitive and convenient use of operation and maintenance. Also, operators can use graphic and text based interface to display information, configure, and access alarm status via various commands on Smart MBS. However, for resource GROW, DEGROW, or neighbor list configuration where several NE needs to be configured, each of the respective BSM/WSM/LSM-R should to be used to make such changes. Operator Authentication Feature Smart MBS provides authentication and restricted management feature for operator who manages Samsung Multi-modal system. Operator can access Smart MBS via console terminal with ID and Password, and Smart MBS acknowledges corresponding users operation level. Smart MBS logs the history at access success, failure, or login. Maintenance Feature with Improved Security When communicating with BSM/WSM/LSM-R, Smart MBS supports SNMP(Simple Network Management Protocol version), FTP and SFTP(SSH File Transfer Protocol) for security. When SAMSUNG Electronics Co., Ltd. 2-11 Smart MBS Abstract communicating with console terminal, it supports HTTPs(Hyper Text Transfer Protocol over SSL), and SSH(Secure Shell). For operation and maintenance, Smart MBS provides secured management features for display and configuration for operational parameter, alarm status management, statistics for various performance data, diagnostics for resource and services, call trace, and system access and operation. On-line Software Upgrade When Software package is upgraded, Smart MBS can upgrade the package while the existing software package is running. Package upgrade is processed as new package download(Prepare) => Change to new package(Change)=>Remove the former package(Complete). At package upgrade, since existing process needs to be terminated during change to new package step to allow new process to run, service is temporarily interrupted. However, since OS does not need to be reset, service can be provided within few minutes. After Software upgrade, Smart MBS should update package stored in the nonvolatile storage. Also, Smart MBS may re-execute the change to new package step to roll back to the package prior to the upgrade. Call Trace Feature Smart MBS can support call trace feature for specific UE(User Equipment) Operator can configure trace for specific UE via BSC/MME or ACR/BS. At this time, trace result(such as signaling message) are sent to operational server (such as BSM/WSM/LSM-R). TCA(Threshold Cross Alert) Control Operational Servers such as BSM/WSM/LSM-R defines under/over threshold for statistical items. If the total statistical values(obtained periodically per configured Bucket interval : 15, 30, or 60 min ) are smaller than under threshold, under TCA alarm is triggered. If it is greater than over threshold, over TCA alarm is triggered. Per classification of each statistical group, TCA can configure threshold per each severity. IEEE 802.3ah Smart MBS provides IEEE 802.3ah Ethernet OAM feature for backhaul interface. Although IEEE 802.3ah OAM is considered as PHY layer, it is located in MAC layer to allow it to be applied to entire IEEE 802.3 PHY layer. As defined in the standard, it generates and processes 802.3ah OAM frame. Ethernet OAM features include discovery (which discovers each others link, continuously monitors connectivity, and sends major link event such as Dying Gasp), remote loopback, link monitoring(which monitors error packets to send event notification if it is greater than the threshold ), variable retrieval for 802.3ah standard MIB. Smart MBS supports 802.3ah Ethernet OAM passive mode features including response and loopback mode for 802.3ah OAM feature which is triggered from external Active Mode entity, and event notification transmission. 2-12 SAMSUNG Electronics Co., Ltd. Smart MBS System Description OAM Traffic Throttling Per operators command, Smart MBS provides feature that can limit the OAM related traffic which can be caused from system. At this time, the target OAM traffic includes alarm trap message which is used for alarm report, and periodically collected statistical file. In case of alarm trap, operator can use alarm inhibition command to limit the alarm for entire system alarm or particular alarm traps. Therefore, amount of alarm traffic can be controlled. In case of statistical file, operator can use statistics collection command to disable the collection feature, and adjust the size of statistical file.

RRH is mounted right before the antenna. In case of Downlink, RRH converts the data traffic, Digital I/Q and C & M(received from UADU), into RF signal to send it via external antenna. At this time, the Transmit RF power from antenna ports is as follows.

Smart MBS System Description Via Digital I/Q and C & M interface, RRH receives UADU clock information, and exchanges alarm and control messages. Figure 3.4 RRH-C2 (800MHz) Figure 3.5 RRH-P4(1.9GHz) SAMSUNG Electronics Co., Ltd. 3-3 Smart MBSs Hardware Structure 3.1 Internal System Architecture Following is the internal block Figure for each communication technology of Smart MBS. 3.1.1 CDMA Internal System Architecture Figure 3.6 Smart MBS CDMA Internal Block Diagram 3-4 SAMSUNG Electronics Co., Ltd. Smart MBS System Description A. CDMA Traffic Architecture Transmit path When User Data is received from BSC via Public Network, it goes through Network Synchronization Module, and sent out to CICA via Ethernet Switch of CIMA(Main board). The transmitted data goes through Digital Processing of the Baseband level, then converted to E/O(Electrical to Optic) in form of [Baseband I/Q and C&M interface] which is based on CPRI interface in CIMA. The converted signal is then sent out to remote RRH. RRH converts the received optic signal via O/E(Optic to Electrical) process. The converted broadband baseband signal is then converted to analog signal, and goes through amplifier for amplification. The amplified signal is then filtered through the band pass filter of the operating frequency, and transmitted. Receive Path The RF signal that was transmitted from Antenna is filtered by RRH, and amplified via LNA. This signal then goes through RF Down-Conversion and Digital Down-Conversion to be converted into baseband signal. This signal is in form of [Baseband I/Q and C&M interface] which is based on CPRI interface, and goes through E/O(Electrical to Optic) conversion once again. The converted signal is then sent to CIMA-A via fiber optic cable, it is converted into Ethernet frame by CDMA baseband signal processor of CICA, and sent to CIMA-A(main board). Finally, it goes through network synchronization module to be sent out to BSC. B. CDMA Clock Architecture UCCM of CIMA-A receives GPS signal from external GPS Antenna, and create the necessary synchronization clock, and distributes it into systems hardware blocks. When CIMA-A is operated with LTE, CIMA-A provides clock to LTE digital boards. CIMA-A provides 10MHz, PP2S, and SFN(System frame number) to each slot via backboard. CICA and LTE Digital boards use this to generate the required clock. C. CDMA Alarm Architecture CDMA Alarm is based on CIMA-A. CIMA-A collects the alarm from Smart MBS, and reports it to upper layer, and can provide Board Reset. SmartPack collects the outdoor cabinets environmental alarm and battery monitoring information, and report to CIMA-A via EAIU4-U. EAIU4-U is mounted inside the Outdoor DU cabinet to synchronize SmartPack, and collect UDA. RRH uses CPRI interface to exchange alarm and control signal with CIMA-A.

Smart MBS System Description A. LTE Traffic Architecture Transmit Path When User Data is received from EPC via Public Network, it goes through Network Synchronization Module, and sent out to L9CA via Ethernet Switch. The transmitted data goes through Digital Processing of the Baseband level, then converted to E/O(Electrical to Optic) in form of [Baseband I/Q and C&M interface] which is based on CPRI interface. The converted signal is then sent out to remote RRH. RRH converts the received optic signal via O/E(Optic to Electrical) process. The converted broadband baseband signal is then converted to analog signal, and goes through amplifier for amplification. The amplified signal is then filtered through the band pass filter of the operating frequency, and transmitted from Antenna. Receive Path The RF signal that was transmitted from Antenna is filtered by RRH, and amplified via LNA. This signal then goes through RF Down-Conversion and Digital Down-Conversion to be converted into baseband signal. This signal is in form of [Baseband I/Q and C&M interface] which is based on CPRI interface, and goes through E/O(Electrical to Optic) conversion once again. The converted signal is then sent to remote L9CA via fiber optic cable. After the data goes through OFDMA signal processing in L9CA, it is converted into Gigabit Ethernet frame, and sent to EPC via network synchronization module B. LTE Clock Architecture UCCM of UAMA receives reference signal from external GPS Antenna, and generate PP2S, Digital 10 MHz, SFN(System Frame Number), and distribute them into L9CA in the system. L9CA then receives PP2s, Digital 10 MHz clock. It should use its own PLL to generate system clock (30.72MHz), CPRI Reference Clock(122.88MHz), and 10msec clock to distribute it to RRH. At synchronization of UADU and RRH, RRH receives the necessary system clock and sync clock that are required for CPRI interface, from L9CA. If LTE system is mounted DU Shelf identical to CDMA, it is supplied the clock for operation from CIMA-A C. LTE Alarm Architecture LTE Alarm is based on UAMA. UAMA collects the alarm from Smart MBS, and reports it to upper layer, and can provide Board Reset. SmartPack collects the outdoor cabinets environmental alarm and battery monitoring information, and report to UAMA via EAIU4-U. EAIU4-U is mounted inside the Outdoor DU cabinet to synchronize with SmartPack, and collect UDA. RRH uses CPRI interface to exchange alarm and control signal with UAMA.

CPS is responsible for data transmission in order to provide wireless data service such as MAC scheduling, air link control, ARQ processing, S1, and X2 message processing. OAM(Operation And Maintenance) For interface with LSM and Web-EMT, OAM provides standardized interface(SNMPv2c, SNMPv3, SFTP, HTTPs, or SSH) with improved security. Also, for OAM of LTE eNB, it performs call processing, collects performance data, manages system configuration and resource, manages software/hardware resources, manages alarm, and performs diagnosis. 4-6 SAMSUNG Electronics Co., Ltd. Smart MBS System Description 4.2 Loading Flow Loading is the process where each processors and devices downloads the required software and data from IS. In Smart MBS, Loading is executed during the system initialization. Also, if particular board is newly mounted onto the system, or if hardware reset is executed, or manually reset by upper management system, loading will be executed. Loading can be classified into two types : loading using Non-volatile storage, or loading using remote IS. At first system initialization, Smart MBS uses remote IS to execute loading. At this time, it stores the corresponding data in its internal storage that unnecessary loading will be prevented in the future. After first initialization, if additional loading is executed, it should compare the version. If the stored data is of the latest version, remote loading will NOT be executed. If stored data is NOT the latest, it will execute remote loading from BSM. Loading file contains Software image(consists of executable file and script file), PLD(related to configuration data and operation parameter), and other configuration files. Among these, all the necessary data, for the static Routing function of Smart MBS, is stored in its own storage as ENV (CDMA)/Startup config(WiMAX) file, and that the required data will be provided at the initialization. Loading Procedure At initialization of Smart MBS, Loader first executes the following tasks in order to execute loading procedure. (Pre-loading) Boot-up

: Booter of Flash ROM copies kernel and RFS(Root File System) from Flash ROM to RAM Disk, to execute kernel. IP Configuration

: In order to communicate with upper management system for the first time, IP address data is obtained from flash ROM, and configured. In case of auto initialization, Smart MBS automatically obtains L3 information (such as IP address, subnet mask, and gateway IP) using DHCP. Registration

: Register NE using RS, and obtain IP address of IS during the registration. Version Comparison

: Except for the case of forced loading, Software image and PLD versions, stored in remote IS and internal storage, are compared to determine where to execute the loading. File List Download

: Download the list of files needs to be loaded per each board. Loading Message Flow After executing Pre-Loading step, loading method is determined. Main OAM(which is responsible for OAM of entire Smart MBS) should execute loading from either the corresponding IS or from its storage using SFTP. After this, Main OAMs loader now becomes internal IS to lower boards, and rest of the loading is executed. The loaded software information of Smart MBS can be checked from upper SAMSUNG Electronics Co., Ltd. 4-7 Smart MBS Software Architecture management system. Loading message flow is shown in the following diagram. BSM/WSM/LSM-R
