Chapter 1 Introduction

Chapter 1 Introduction 1.1 Huawei WCDMA NodeB Family 1.1.1 Overview of Huawei WCDMA NodeB Family Huawei WCDMA NodeB family includes BTS3812, BTS3806, BTS3806A, BTS3802C, and RRU. This chapter presents Huawei WCDMA NodeB family from the perspectives of type, capacity, configuration supported, and the components of cabinets.

1.1.2 BTS3812 BTS3812 is an indoor macro NodeB with large capacity, supporting up to 12 cells. The BTS3812 supports combined cabinets, which have larger capacity as up to 24 cells. In addition, BTS3812 supports cascading with several remote radio units (RRU) configuration. A BTS3812 cabinet includes a baseband subrack, a radio frequency (RF) subrack and a linear power amplifier (LPA) subrack. The baseband subrack performs the baseband processing of NodeB service data. The RF subrack performs the intermediate frequency (IF) and RF processing of NodeB service data. The LPA subrack amplifies downlink (DL) RF signals and enhances power.

1.1.3 BTS3806 BTS3806 is an indoor macro NodeB with medium capacity, supporting up to six cells. BTS3806 supports cascading with several RRUs. BTS3812 and BTS3806 use the same types of boards and modules, and work with the same operational principles. However, BTS3806 has smaller capacity, and the number of some types of boards is smaller than that of BTS3812.

1.1.4 BTS3806A BTS3806A is an outdoor macro NodeB with medium capacity, supporting up to six cells. BTS3806A can adapt itself to complicated climates and electro-magnetic environments. It is an important supplement to indoor NodeBs. BTS3806A supports cascading with several RRUs. BTS3806 and BTS3806A use the same types of boards and modules, and work with the same operational principles. However, some other modules, for example, the temperature control device, environment monitoring device, transmission device, and

battery, are integrated into the BTS3806A cabinet, thus making the NodeB an independent and integrated system that meets the protection requirements of outdoor equipment.

1.1.5 BTS3802C BTS3802C is an indoor or outdoor mini NodeB, supporting up to two cells. BTS3802C features high integration, small size, and easy installation. As an mini NodeB, BTS3802C can perform NodeB services independently. A BTS3802C cabinet includes one NodeB main control unit (NMCU), one NodeB power supply unit (NPSU), and two NodeB digital and radio units (NDRU). The NMCU performs the baseband processing of NodeB service data. The NDRU performs the IF and RF processing of NodeB service data. NPSU provides BTS3802C with working power supply.

1.1.6 RRU RRU is an indoor or outdoor remote radio unit, supporting up to two cells. It features high integration, small size and easy installation. As a remote radio unit of such macro NodeBs as BTS3812, BTS3806 and BTS3806A, RRU needs to cooperate with its macro NodeB to complete NodeB services. RRU share the baseband processing and NodeB main processor and timing unit (NMPT) resources of a macro NodeB by connecting with it through fibers. An RRU cabinet includes one NodeB radio remote interface (NRRI), one NPSU, and two NDRUs. The NRRI, together with NodeB interface processing units (NIFP) in a macro NodeB, transfers RRU service data to the macro NodeB. The macro NodeB performs the baseband processing of RRU service data. The NDRU performs the IF and RF frequency processing of NodeB service data. The NPSU provides RRU with working power supply.

Note: The subsequent signal flow direction of NDDLx, where “x” corresponds to the NDDL number, is as follows: z

The amplified RF main signals enter NDDLx through the “NDDLx_TXM” port on the backplane. After that, the signals run from the “ANTA” port on the NDDLx to the “ANT_xA” antenna connector on the cabinet top through the internal RF cables. Finally, the signals are transmitted through the antenna and feeder system connected to the “ANT_xA” port.

z

The amplified RF diversity signals enter NDDLx through the “NDDLx_TXD” port on the backplane. After that, the signals run from the “ANTB” port on the NDDLx to the “ANT_xB” antenna connector on the cabinet top through the internal RF cables. Finally, the signals are transmitted through the antenna and feeder system connected to the “ANT_xB” port.

2.5.5 RF Port Wiring between NRFB and NPAB for 2-way Rx & 6-Sector Mode Figure 2-13 illustrates the RF port wiring for 2-way Rx and 6-sector mode. The unconnected ports are open. In this case, all the small-signal divider jumpers and small-signal combiner jumpers on the NRFB work in mode B. Figure 2-13 illustrates the RF port wiring in the no Tx diversity mode. For 6-sector configuration, it is impossible to use the Tx diversity mode. For 4-sector or 5-sector 2-14



configuration, the open NRFB ports can connect to the NLPA not used by any sector, achieving Tx diversity for the sector. NRFB

2.5.6 RF Port Wiring between NRFB and NPAB for 4-way Rx Mode For the 4-way Rx mode, the small-signal combiner jumpers on the NRFB work in mode A. The small-signal divider jumpers on the NRFB work in mode B. In this case, the RF port wiring on the backplane is the same as that in 3-sector mode, as illustrated in Figure 2-12. If a sector works in the no Tx diversity mode, the pair of dotted lines in the sector need be removed.

Note: For the economical 4-way Rx mode, the RF processing and RF cable connections are the same as 4-way Rx mode. As for the baseband processing, the DPCHs are processed in the same way as in 4-way Rx mode, while the RACHs are processed in the same way as in 2-way Rx mode.

2-15



2.5.7 RF Port Wiring between NRFB and NPAB for OTSR Mode Figure 2-14 illustrates the RF port wiring for OTSR mode. The unconnected ports on the NRFB are open. In this case, only NLPA3 needs to be configured. It is recommended to set all the small-signal divider jumpers and small-signal combiner jumpers on the NRFB in mode A.

Note: The small-signal divider jumpers and small-signal combiner jumpers on the NRFB can be set either in mode A or in mode B. The two modes have no impact on the NodeB, but have impact on the standby slots of boards. It is recommended to set the jumpers in mode A.

3.5 BTS3806 Backplanes and their RF Port Wiring 3.5.1 Overview of BTS3806 Backplanes and their RF Ports Wiring This part describes the backplanes, backplane jumpers, and backplane wiring related to NodeB configuration types. z

Backplanes: This part presents the backplanes of BTS3806 cabinet and their wiring. The backplanes include the NBCB, NRFB and NPAB.

z

RF port wiring between NRFB and NPAB: This part presents the RF port wiring between NRFB and NPAB under typical NodeB configurations. The wiring depends on NodeB configurations. The typical configurations include 2-way Rx and 3-sector mode and OTSR mode.

3.5.2 Backplanes The backplanes host the boards of BTS3806. They provide power and interconnection signal circuits for the boards inside the subracks, and provide ports for inter-subrack cable connection. BTS3806 includes three backplanes as follows: z

NBCB: The NBCB is on the back of the baseband subrack. There is no jumper on the NBCB. The ports on the NBCB connect the clock and control signal cable between the NMPT and RF subrack, the GBUS cable between the NDLP and NIFP, the I/O cable of the NMON, and power cable.

z

NRFB: The NRFB is on the back of the RF subrack. There is no jumper on the NRFB. The NRFB ports connect to the clock and signal control cable, GBUS cable, RF cable, and power cable.

z

NPAB: The NPAB is on the upper part of the LPA subrack back. Different cable connections on the NPAB support different NodeB configurations. The NPAB allocates power supply and signals to each NLPA, and provides RF input ports and RF output ports.

Notes: z

The RF port wiring on the NRFB and NPAB depend on NodeB configurations. This part focuses on the cable connections. For more details, refer to section 3.5.3 and section 3.5.4 .

z

For the wiring independent of NodeB configurations, refer to section3.6.3 .

Note: The susequent signal flow direction of NDDLx, where “x” corresponds to the NDDL number, is as follows: z

The amplified RF main signals enter NDDLx through the port “NDDLx_TXM” on the backplane. After that, the signals run from the “ANTA” port on the NDDLx to the “ANT_xA” antenna connector on the cabinet top through the internal RF cables. Finally, the signals are transmitted through the antenna and feeder system connected to the antenna connector.

z

The amplified RF diversity signals enter NDDLx through the port “NDDLx_TXD” on the backplane. After that, the internal RF cables transmit the signals from the “ANTB” port on the NDDLx to the “ANT_xB” antenna connector on the cabinet top. Finally, the signals are transmitted through the antenna and feeder system connected to ANT_xB.

3.5.4 RF Port Wiring between NRFB and NPAB in OTSR Mode Figure 3-9 illustrates the RF port wiring in OTSR mode. The unconnected ports on the NRFB are open. In this case, only NLPA1 needs to be configured.
