It has following two reserved ports: The ZXSDR R8860 provides an external port (Rx out) to support the mutual main set/diversity combination mode. The FL main set reception Low Noise Amplifier (LNA) output port delivers the power division function. An electronic switch is set at the receive diversity channel and an external input port is reserved to deliver the compatibility with the long-distance frequency. The system can switch over to input signals through the FL of local Radio Unit (RU) or through another Remote Radio Unit (RRU). Figure 1-8 shows the overall system structure. Figure 1-8 ZXSDR R8860 System Structure 1.8.2 Signal Flow The ZXSDR R8860 signal flow is described below. Forward Flow The forward signal flow consists of following. 1-10 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential Chapter 1 Product Overview 1. After receiving the data modulated by the baseband unit through the Common Public Radio Interface (CPRI) interface, the up conversion is done by the TR and then the signal is sent to Power Amplifier (PA). 2. The PA amplifies the power of signals and then sends it to the (Duplex Filter) DFL. 3. The FL duplexes and filters the RF signals and then transmits it through the antenna. Reverse Flow The reverse signal flow consists of the following. 1. The FL filters the backward CDMA signals from the antenna, amplifies the power of these signals before sending them to the TR. 2. The TR performs down conversion and converts the signal into baseband digital signals and then transmits to the baseband unit through the CPRI interface. 1.9 Networking 1.9.1 Baseband-RF Interface Networking The ZXSDR R8860 is connected to the Base Band Unit (BBU) by optical interfaces. It supports the Common Public Radio Interface (CPRI) protocol, and star and chain networking modes, as shown in Figure 1-9. Figure 1-9 ZXSDR R8860 Baseband-RF Interface Networking Star networking: the networking mode adopts point-to-point connection, so the number of fibers led out of the baseband unit is the same as the total number of RF modules. Although many fibers are needed, the networking mode is more reliable than the chain networking. Chain networking: the networking mode requires fewer fibers but has lower reliability. 1-11 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential ZXSDR R8860 Technical Manual 1.9.2 Cascade Networking In the case where RRUs are close to each other but are far away from BBU, the cascade networking through CPRI interface is recommended to save optical fibers. Alternatively, a cascade networking is also type of chain networking. Figure 1-10 shows the cascade networking through CPRI interface. Figure 1-10 ZXSDR R8860 Cascade Networking RRUs are connected by optical fiber. The RRU optical interface LC1 serves to connect BBU or the upper level RRU while LC2 serves to connect the lower level RRU. 1.9.3 Frequency Extension Networking ZXSDR R8860 supports mutual receive diversity by means of cabinet combination so that it can support high-carrier or great-carrier-frequency-difference application. Figure 1-11 shows the frequency extension networking mode supported by ZXSDR R8860. 1-12 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential Chapter 1 Product Overview Figure 1-11 ZXSDR R8860 Frequency Extension Networking 1.10 Equipment Management Modes 1.10.1 OMC Mode The NetNumen™ M3 network management system (NMS) developed by ZTE can be used to operate and maintain the ZXSDR R8860, as shown in Figure 1-12 1-13 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential ZXSDR R8860 Technical Manual Figure 1-12 ZXSDR R8860 Operation and Maintenance –OMC Mode The Network Element (NE) communicates with the NMS through the TCP/IP protocol.

For the electrical antenna, you can adjust the lever to control the embedded adjuster and thus to tune the downtilt angle of the antenna. The tilt reflects the direction from which the 2-14 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential Chapter 2 Hardware Descriptions antenna receives the strongest signals. The tilt of the uni-directional antenna can be tuned mechanically, and electrical tilt is used to tune the omni-directional antenna. The principle of the electrical tilt is as follows: The adjustment of the phase of the antenna array vibrator changes the maximum vertical and horizontal components and alters synthesized field strength, thus making the vertical pattern of the antenna declining. Because the antenna field strength increases or decreases simultaneously in all directions, which ensures that the antenna pattern hardly varies with the tilt. This diminishes the coverage of the main lobe and ensures that no interference occurs when the coverage of the whole pattern decreases in its service area. 2.4.3 Feeder Structure The feeder is used to receive and transmit radio RF signals between the antenna and the ZXSDR R8860. There are many types of feeder cables such as 1/2 inch and 7/8 inch feeder cable. When the distance between the ZXSDR R8860 cabinet and antenna is less, then 1/2 inch feeder cable is used. In this case, the ZXSDR R8860 cabinet is directly connected to the 1/2 inch feeder and 1/2 inch feeder cable is connected to antenna. When the distance between the ZXSDR R8860 cabinet and antenna is more, then 7/8 inch feeder cable is used. In this case, ZXSDR R8860 cabinet is first connected to the jumper, then jumper is connected to 7/8 inch feeder cable, and 7/8 inch feeder cable is again connected to jumper and lastly jumper is connected to antenna. The antenna may have N type or DIN type interface. The feeder is adapted to female and male N connectors. Usually both ends of the delivered feeder are male N connector to facilitate on-site installation. 2-15 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential ZXSDR R8860 Technical Manual This page intentionally left blank. 2-16 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential Chapter 3 Protocol Interface Description Table of Contents Network Reference Model ..........................................................................................3-1 Um Interface ..............................................................................................................3-2 Baseband—RF Interface ............................................................................................3-6 3.1 Network Reference Model Figure 3-1 shows the network reference model of the CDMA2000 1x network.

It provides basic radio channels to transmit information of upper layers. 3-2 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential Chapter 3 Protocol Interface Description The data link layer comprises of Medium Access Control (MAC) sublayer and Link Access Control (LAC) sublayer. The MAC sublayer implements the mapping between logical channels and physical channels and delivers the Radio Link Protocol (RLP) function. The LAC sublayer performs authentication, automatic request retransmission, addressing, segment and reassembly. The uppermost layer provides signaling service, voice service, packet data application and circuit data application, and implements radio resource, mobility and connection management of the air interface through signaling service. CDMA2000 1x EV-DO Um interface The CDMA2000 1x EV-DO Um interface is divided into application layer, stream layer, session layer, connection layer, security layer and physical layer. The Um interface meets the IS-856 protocol standard. Every layer defines one or more protocols to realize its function. Figure 3-3 illustrates the overall protocol reference model. Figure 3-3 1xEV-DO Um Interface Protocol Reference Model Application layer The application layer provides multiple applications, such as Default Signaling Application for transmitting air interface messages and Default Packet Application for transmitting data. The Default Signaling Application defines two protocols, Signaling Network Protocol (SNP) and Signaling Link Protocol (SLP). The protocols on all layers exchange messages through SNP . SLP implements message segment and assembly, Best-effort transmission, reliable transmission and duplicate packet detection. 3-3 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential ZXSDR R8860 Technical Manual The Default Packet Application provides a byte stream to transmit packet data between the terminal and the network. It includes three protocols. à Flow Control Protocol provides the flow control function for data stream. à Radio Link Protocol implements byte stream retransmission and duplicate packet detection, and provides a reliable data link for upper applications. à Location Update Protocol provides location update program and corresponding messages for mobility management of packet application. Stream layer The stream layer delivers the following functions: à It provides the architecture of data packets over the connection application layer by means of data stream authentication. à It distinguishes priorities signals and user services according to the data encapsulation protocol of the connection layer. à It connects users to signal service. à It allocates independent data stream to applications of different QoSs. Session layer The session layer contains a series of protocols used for session negotiation between the terminal and the network. In the 1xEV-DO system, a session indicates a state jointly maintained between Access Terminal (AT) and Access Network (AN). It includes address UATI distributed to the terminal, protocol set determined by the terminal and the network for air interface communication, protocol configurations in the protocol set and current terminal location. The session layer defines three protocols: à Session Management Protocol activates other protocols on the layer, ensures session validity and closes sessions. à Address Management Protocol manages terminal address (UATI) distribution. à Session Configuration Protocol (SCP) performs session flow negotiation. In the 1xEV-DO system, SCP negotiates the protocol used for communication between the terminal and the network, and how to set protocol parameters. Connection layer The connection layer controls the air link state. In the 1xEV-DO system, an enabled link between AT and AN means the AT is allocated with RPC, RTC and FTC (FTC is the time division channel shared by all the subscribers with open connections in the sector). Security layer The security layer delivers the following functions: à Key exchange. It provides a procedure for the terminal and the network to exchange keys that are used for authentication and encryption. 3-4 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential Chapter 3 Protocol Interface Description à Authentication.

It provides a procedure for the terminal and the network to encrypt over-the-air services. The security layer covers four protocols, among which Key Exchange Protocol, Authentication Protocol and Encryption Protocol define the three functions mentioned above respectively while Security Protocol provides public variables for Authentication Protocol and Encryption Protocol. MAC layer The MAC layer defines the rules for managing control channel, access channel, forward traffic channel and reverse traffic channel. It contains four protocols, as described below: à Control Channel MAC Protocol constructs Control channel MAC layer packet from one or more Security layer packets, controls packet scheduling and transmission rule of channels and regulates how the terminal captures the control channel and receives control channel packets. à Access Channel MAC Protocol defines that the terminal sends timing messages and power features over the access channel. à Forward Traffic Channel (FTC) Protocol regulates how to control the rate of the FTC through the DRC and how to support the fixed rate mode and variable rate mode of the FTC. à Reverse Traffic Channel (RTC) Protocol regulates how the terminal assists the network to capture the RTC and how the terminal and the network choose RFC rate. Physical layer The physical layer defines structure, frequency, power output, modulation/demodulation and coding/decoding of the forward/reverse channel. BCMCS Um Interface The Broadcast and Multicast Service (BCMCS) Um interface implements broadcast and multicast services. Figure 3-4 shows the structure of the BCMCS Um interface protocol stack. 3-5 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential ZXSDR R8860 Technical Manual Figure 3-4 Structure of the BCMCS Um Interface Protocol Stack Broadcast Control Protocol processes BCMCS stream registration. The AT sends the stream registration request to the AN so that the AN can broadcasting the stream continuously. Broadcast Framing Protocol encapsulates, segments and delimits upper layer packets. Broadcast Security Protocol provides packet encryption mechanism. Broadcast MAC Protocol adds forward error correcting codes to form Error Control Block (ECB) and relays MAC frames to the physical layer. The layer is responsible of logical channel mapping, constructing and sending broadcast overhead messages. Broadcast Physical Protocol provides a logical channel structure. 3.3 Baseband—RF Interface The baseband-RF interface of ZXSDR R8860 complies with the common public radio interface (CPRI) specification. The CPRI specification was instituted by the CPRI Union, which is an industry cooperation organization devoting itself to institution of internal radio interface specifications of radio base stations. The CPRI specification describes the transmission, control and synchronization mechanisms of user data and control signaling, defining the essential factors such as transmission, connection and control. From a view of the specification system, the CPRI specification contains the contents of physical layer and data link layer. It describes characteristics of electrical and optical interfaces and multiplexing mechanisms among various data flows in the matter of the physical layer, and media access control (MAC ), flow control and information flow protection in the matter of the data link layer. 3-6 SJ-20100722143906-001|08/30/2010 ZTE Proprietary and Confidential Figures Figure 1-1 Distributed ZTE BTS Solution
