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




1-2

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.

2.5 BTS3812 Backplanes and their RF Port Wiring

2.5.1 Overview of BTS3812 Backplane and their RF Port Wiring

This part describes the backplanes, backplane jumpers, and the RF port wiring related

to NodeB configuration on the backplanes.

Backplanes: This part presents the backplanes of BTS3812 cabinet and their

wiring. The backplanes include the NBCB, NRFB and NPAB.

NRFB jumpers: This part presents the NRFB from the aspects of function, setting

mode and relation to NodeB configuration.

RF port wiring between NRFB and NPAB: This part presents the RF port wiring

between NRFB and NPAB under different typical NodeB configurations. The wring

depends on NodeB configurations. The configurations include 2-way Rx and

3-sector mode, 2-way Rx and 6-sector mode, 4-way Rx mode, and

omni-directional transmit & sector receive (OTSR) mode.

2.5.2 Backplanes

The backplanes host the boards of BTS3812. They provide power and interconnection

signal circuits for the boards inside the subracks, and provide ports for inter-subrack

cable connection. Different jumper connections on the NRFB support different NodeB

configurations.

BTS3812 includes three backplanes as follows:

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 signal control cable

between the NMPT and RF subrack, the GBUS cable between the NDLP and

NIFP, the input/output (I/O) cable of the NMON, and power cable.

NRFB: The NRFB is on the back of the RF subrack. Different jumper connections

on the NRFB support different NodeB configurations. For details about NRFB

jumpers, refer to section 2.5.3 "NRFB Jumpers”. The NRFB ports connect to the

clock and signal control cable, GBUS cable, RF cable and power cable.

NPAB: The NPAB is on the upper part of the LPA subrack back. Different cable

connections on the NPAB, together with the jumper connections on the NRFB,

support different NodeB configurations. The NPAB allocates power supply and

signals to each NLPA, and provides RF input ports and RF output ports.

Note:

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 the following sections: Section 2.5.4 , Section 2.5.5 ,

Section 2.5.6 , Section 2.5.7 .

For the wiring independent of NodeB configurations, refer to section 2.6.3 .

2.5.3 NRFB Jumpers

I. Introduction to NRFB Jumpers

There are 12 small-signal divider jumpers and small-signal combiner signals on thefront side of the NRFB, that is, the side hosting the boards. You must remove the

boards from the NRFB to set NRFB jumpers.

The NRFB includes two parts with six jumpers as the small-signal dividers on the upper

part and six jumpers as the small-signal combiners on the lower part, as illustrated in

Figure 2-10.

II. Settings of NRFB Jumpers

There are two modes of settings for both small-signal dividers and small-signal

combiners as follows:

Mode A for small-signal dividers and small-signal combiners: The settings in this

mode divide one-line RF signals into four lines and combine four-line RF signals

into one line. Figure 2-10 illustrates the jumpers on the NRFB in mode A. All the

small-signal jumpers connect to the MCX sockets on the left.

Mode B for small-signal dividers and small-signal combiners: The settings in thismode divide one-line RF signals into two lines and combine two-line RF signals

into one line. Figure 2-11 illustrates the jumpers on the NRFB in mode B. All the

small-signal jumpers connect to the MCX sockets on the right.

Note:

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

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.

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.


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

configuration, the open NRFB ports can connect to the NLPA not used by any sector,

achieving Tx diversity for the sector.

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.




2-16

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.

Backplanes: This part presents the backplanes of BTS3806 cabinet and their

wiring. The backplanes include the NBCB, NRFB and NPAB.

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:

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.

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.

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:

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 .

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


Figure 3-8 illustrates the RF port wiring for 2-way Rx and 3-sector mode. The

unconnected ports are open.

Note:

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

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.

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.
