3 Working Principle and Function of the BBUThe BBU is a baseband processing unit. It processes baseband signals of a base station.

Working Principle

BBU consists of the following subsystems: baseband subsystem, cabinet subsystem,transmission subsystem, interconnection subsystem, main control subsystem, monitoringsubsystem, and clock subsystem. Each subsystem consists of different modules.l The baseband subsystem consists of the baseband processing unit.l The cabinet subsystem consists of the backplane, fan, and power modules.l The transmission subsystem consists of the main control and transmission unit as well as

the transmission extension unit.

l The interconnection subsystem consists of the main control and transmission unit (a) as wellas the infrastructure interconnection unit.

l The main control subsystem consists of the main control and transmission unit.l The monitoring subsystem consists of the power module and monitoring unit.l The clock subsystem consists of the main control and transmission unit as well as the

universal satellite card and clock unit.

NOTE

(a) In the interconnection subsystem, the UMPT is used as a main control and transmission unit.

The following figure shows the working principle of a BBU.

Figure 3-1 Working principle of a BBU

Function

The BBU performs the following functions:

l Provides ports for connecting to the transmission equipment, RF modules, USB devices a,external reference clock, and LMT or U2000 to provide signal transmission, performautomatic software upgrade, receive reference clock, and support BBU maintenance on theLMT or U2000.

l Manages the entire base station system. The management involves the processing of uplink and downlink data, signaling processing, resource management, and operation andmaintenance.

NOTE

a: The security of the USB port is ensured by encryption, and the USB port can be shut down usingcommands. The USB commission port is used for commissioning the base station rather than configuringand exporting information of the base station.

l The baseband processing board in UMTS mode configured in only slot 3 or 2 can be connected CPRIcables. The UBBPd_U, WBBPd, or WBBPf is preferentially configured in slot 3 or 2. The priority of

the three kinds of boards is UBBPd_U > WBBPf > WBBPd.l If five or more baseband processing boards working in UMTS mode are required, ensure that WBBP

or UBBPd_U boards are installed in both slots 2 and 3. At least one of the boards in slots 2 and 3 isUBBPd_U, WBBPd, or WBBPf.

l If both slots 2 and 3 are occupied by the WBBPa or WBBPb boards, exchange boards to ensure thatthe UBBPd_U, WBBPd, or WBBPf is configured in slot 3 or 2. The UBBPd_U, WBBPd, or WBBPf is preferentially configured in slot 3.

BBU Slot Assignment in a UL Base StationNOTE

l The UL base station is a separate-MPT base station. That is, the BBU houses two main control boards,in which one works in UMTS mode and the other works in LTE mode.

l The U*L/U*T base station is a co-MPT base station. That is, the main control board in the BBU worksin both UMTS mode and LTE mode.
