1 Overview

1.1 Introduction

This document provides a high level description of the distributed baseband processing Unit (BBU) ZXSDR B8200 (hereinafter B8200) that used in ZTE multi-mode wireless solutions.

The baseband unit B8200, can be inserted into the integrated macro base station, or connected to RRU in distributed base station. It is responsible for processing the baseband signals. Based on ZTE SDR platform, it supports GSM, UMTS and FDD LTE single-mode or multi-mode by software configuration. It enables operators to deploy one unified radio access network rather than independent GSM, UMTS or LTE network, which brings simplicity and convenience with low CAPEX and OPEX. Figure 1 sho ws the position of the ZXSDR B8200 in the typical multi-mode network.

Figure 1-1 B8200 in the GSM/UMTS/LTE Network

Chapter 2 gives the architecture, functionality, services and multi-system cooperation. Chapter 3 covers system capabilities, and chapter 4 introduces configuration principles of each kind of boards used in B8200.

1.2 Benefits

(9)

B8200 supports all kinds of wireless access technologies simultaneously, including GSM, UMTS and LTE, which share the common control function and transmission totally. It fully satisfies operators’ need with the minimum hardware change .

 Large Capacity

To adapt to the rapid expansion of network development and the prosperity of multi-mode network, the latest BBU boards are released with higher processing capacity. The capacity indices of new boards surpass legacy ones, including RRC connected user number, cell number and data throughput. The increase in the board capacity improves the overall capacity of BBU. In addition, the new boards can be used together with the legacy ones, which provide flexibility during upgrade.

 Plug-in Design for Shelf, Zero Footprint, Convenient Deployment

B8200 adopts Plug-in design with 19-inch, 2U in height and 8.75 kg (with full configuration) in weight. It can be conveniently mounted on the wall, ground, or in the 19-inch rack, etc.

 Flexible Networking

B8200 provides GE/FE interfaces and IP networking. It supports RRU in different networking modes, like star and chain networking to satisfy the requirements of operators in different environments and under different transmission conditions.

1.3 Application Scenarios

As the baseband processing unit, B8200 is widely used in ZTE series of base stations, including indoor macro BS of ZXSDR BS8800, outdoor macro BS of ZXSDR BS8900A/BS8900B, distributed BS of ZXSDR BS8700 and outdoor compact BS of ZXSDR BS8906.

 RNLC (radio network layer control) provides common and dedicated radio resource management and control functions for control plane

 RNLU (radio network layer user) provides user plane function

GSM/UMTS/LTE A lication Software

OMC-B SCS OAM DBS BRS Hardware (BSP) Linux LMT OSS

(31)

 SCHEDULER (scheduler sub-system) provides uplink/downlink MAC scheduling

 PHY (physical layer) provides PHY function

The SDR platform software provides the functions of Operation Support Sub-system (OSS), Operating And Maintenance (OAM), Data Base Sub-system (DBS), Bearer Sub-system (BRS) and System Control Sub-system (SCS):

 OSS is the support layer in this entire framework, which is a hardware independent

platform for running software and provides basic functions like scheduling, timer, memory management, communication, sequencing control, monitoring, alarming and logging.

 OAM provides the configuration, alarm and performance measurement function for

base station.

 DBS is the database system.

 BRS provides the IP communication function for inter-board and inter-network

elements.

 SCS provides the power control and system management function.

Board Support Package (BSP) is the software closely connected with the board hardware and supports Real Time Operation Support Sub-system (RT OSS) to work on the board.
