1.1 ZTE Distributed Base StationSolutionTo supply the customer with more competitive communicationequipment and solution in the market, ZTE develops and pro-motes ZTE SDR eBBU (baseband unit) and eRRU (remote RF unit)distributed base station solution timely, which jointly perform LTEbase station service.

ZTE distributed base station solution is shown in Figure 1.

2 Confidential and Proprietary Information of ZTE CORPORATION

Chapter 1 Product Overall Description

FIGURE 1 ZTE DISTRIBUTED BASE STATION SOLUTION

ZTE's LTE eBBU+eRRU distributed base station solution has thefollowing predominance:

1. Saving labor cost and engineering cost for networking.

eBBU+eRRU distributed base station equipment is small insize, light in weight, and easy for transportation and engineer-ing construction.

2. Fast networking, also saving the fees of renting equipmentroom.

eBBU+eRRU distributed base station is applicable to varioussites, such as mounted on the steel tower, on the building top,or on the wall, etc. It's more flexible in selecting installationsite, and not restricted by the space of the equipment room.It can help the operators to deploy network rapidly, and exertthe predominance of Time-To-Market. It can also save the feesof renting equipment room, and the network operation cost.

3. Convenient in upgrade and capacity expansion; saving the ini-tial stage cost of the network.

eRRU can be mounted as close to the antenna as possible, tosave the cost of feed cable and decrease the wastage of feedcable. It also can enhance the output power of eRRU top andincrease the coverage.

4. Low power consumption, power-saving.

Compared with traditional base station, eBBU+eRRU dis-tributed base station has lower power consumption, which cangreatly reduce the investment and cost on electric power, andthus save the network operation cost.



5. Distributed networking, making good use of operators' net-work resources supporting eBBU+eRRU distributed network-ing; supporting the star or chain networking mode betweeneBBU and eRRU.

6. Adopting more perspective generalized base station platform.

eBBU adopts the platform designed for the future B3G and 4G.One hardware platform can realize different standard modes,and several standard modes can coexist in one base station.In this way, the operators' management can be simplified, andseveral base stations to be invested can be integrated into onebase station (multimode base station). The operators can se-lect the evolution direction of the future network more flexibly,and the end users will also feel the transparency of the networkand smooth evolution.

1.2 Product Location in LTEWireless NetworkLTE is a new-generation wireless network technology based onOFDM technology. The main aims of formulating LTE standardsare:

� To provide higher user data rate, enhance system capacity,decrease delay and operation cost.

� To realize the flexible configuration and implementation of themobility of a present or new access technology based on IPnetwork.

LTE has optimized the traditional 3G network architecture, andadopts flat network structure. LTE system consists of EPC andeNodeB. EPC is responsible for the core network. EPC's signal-ing processing part is called as MME, and the data processing partis called as SAE Gateway (S-GW). eNodeB is responsible for theaccess network, being also called E-UTRAN. eNodeB and EPC areconnected via S1 interface; eNodeB and other eNodeBs are con-nected via X2 interface.

ZXSDR B8200 L200 realizes the function of eNodeB's basebandunit, and forms a complete eNodeB with the RF unit (eRRU) viathe baseband-RF interface. ZXSDR B8200 L200 and EPC are con-nected via S1 interface; and are connected with other eNodeBs viaX2 interface.

The location of the ZXSDR B8200 L200 in LTE network is as shownin Figure 2.

1.3 Product Overall AppearanceZXSDR B8200 L200 overall appearance is as shown in Figure 3.

FIGURE 3 PRODUCT OVERALL APPEARANCE

1.4 Product CharacteristicsMulti-Mode

Baseband UnitZXSDR B8200 L200 can support all kinds of wireless access tech-nologies simultaneously, including GSM, UMTS, CDMA, WiMAX andLTE, which share the common control function and transmissiontotally. It fully satisfies operators’need of smooth migration fromGSM/UMTS with BP board replaced only.

All-IP Architectureto IP RAN

ZXSDR B8200 L200 adopts IP switching, and provides GE/FE ex-ternal interfaces.

Large Capacity ZXSDR B8200 L200 supports different configurations.

In typical configuration,ZXSDR B8200 L200 supports 200 Mbps DL+ 75 Mbps UL (three 20 MHz cells in MIMO 2x2).

ZXSDR B8200 L200 also supports larger capacity with more BPLbaseband boards:

� 600 Mbps DL + 225 Mbps UL(six 20 MHz cells in MIMO 2x2).

� 600 Mbps DL + 300 Mbps UL(three BPL boards in MIMO 4x4).



ZXSDR B8200 L200 is hardware readiness to support MIMO 4x4without hardware changing. In first GA version, BPL supportsMIMO 4x4 in test mode.

According to the application scenario, ZXSDR B8200 L200 can sup-port GSM/UMTS/LTE multi-mode with respective baseband pro-cessing boards.

Baseband Pooling ZXSDR B8200 L200 supports baseband resource pooling functionbased on carriers. When FS and two BPLs or three BPLs are config-ured, one carrier can be flexibly mapped to any BPL board. But atthe beginning of LTE network deployment, ZTE recommends onlyone BPL is configured in order to reduce the operator’s CAPEX in-vestment.

FlexibleNetworking

ZXSDR B8200 L200 provides GE/FE interfaces and IP networking.It supports eRRU in different networking modes, like star and chainnetworking to satisfy the requirements of operators in differentenvironments and under different transmission conditions.

System control signal flow is shown in Figure 11.

FIGURE 11 CONTROL SIGNAL DATA FLOW

1. Uplink common control signaling flow

i. Uplink PHY on BPL board receives UL common control sig-naling via LTE-Uu interface.

ii. PHY layer performs decoding and demodulation and mapsto the corresponding cell according to global logic indicationof the cell.

iii. RNLU performs MAC protocol processing, RLC protocol pro-cessing, then is sent to GE switch through GE and switchedto RRC signaling protocol processing module of RNLC.

2. Downlink common control signaling flow

i. Contrary to uplink common control signaling flow, down-link common control signaling flow is switched to RNLU onbaseband board by GE switch to perform RLC and MAC pro-tocols processing via RRC protocol processing module onCC board.

Chapter 2 Working Principles

2.3 User Service Data FloweNodeB protocols are divided into two parts: user plane protocoland control plane protocol. Service data signal comes to S-GWafter processing by user plane protocols.

User service data flow is as shown in Figure 12.

FIGURE 12 USER SERVICE FLOW

1. Downlink data flow

When data from the S1 interface arrives at BPL board:

i. GTPU module analyzes the GTPU data, discards the GTPUheader, and then forwards it to PDCP/RLC/MAC for encryp-tion, fragment and scheduling, forwards data to downlinkPHY.

ii. Downlink PHY performs channel coding, scramble, FFT andIFFT, generates IQ data, and then forwards baseband IQdata to eRRU, eRRU performs power amplify, frequencytransformation, forms high frequency signal, transmitshigh frequency signal through antenna over the air.

2. Uplink data flow

i. Uplink PHY receives the antenna data from UE, and senddata to RNLU after corresponding processing.

ii. RNLU extracts various uplink control elements from thedata, and then the dedicated data part are encapsulatedinto GTPU PDU through MAC/RLC/PDCP protocols process-ing.

iii. The processed data is forwarded CC board, and then CCboard achieves data forwarding according to the destina-tion address of GTPU PDU and sends the uplink data toSGW.



2.4 Clock Data FlowCC board delivers system clock signal to all the other boards, clocksignal is sent to eRRU through fiber interface. The clock data flowis as shown in Figure 13.
