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 transmission unit and transmission extension unit.
l
The interconnection subsystem consists of the main control transmission unit(a) and infrastructure interconnection unit.
l
The main control subsystem consists of the main control transmission unit.
l
The monitoring subsystem consists of the power module and monitoring unit.
l
The clock subsystem consists of the main control transmission unit and satellite card and clock unit. NOTE
(a) In the interconnection subsystem, the UMPT is used as a main control transmission unit.

3 Working Principle and Functions of the BBU
Figure 3-1 Working principle of a BBU
Function The BBU performs the following functions: l
Provides ports to connect to the transmission equipment, RF modules, USB devices(a), external reference clock, and LMT or U2000 to provide signal transmission, perform automatic software upgrade, receive reference clock, and support BBU maintenance on the LMT or U2000.
l
Manages the entire base station system, including the processing of uplink and downlink data, signaling processing, resource management, and operation and maintenance. NOTE
a: The security of the USB port is ensured by encryption, and the USB port can be shut down using commands. The USB commission port is used for commissioning the base station rather than configuring and exporting information of the base station.

4 BBU Slot Assignment NOTE
l In a UMTS single-mode base station, the UMPT and WMPT cannot be configured in the same BBU. l The baseband processing board in UMTS mode configured in only slot 3 or 2 can be connected CPRI cables. 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 is UBBPd_U, WBBPd, or WBBPf. l If both slots 2 and 3 are occupied by the WBBPa or WBBPb boards, exchange boards to ensure that the UBBPd_U, WBBPd, or WBBPf is configured in slot 3 or 2. The UBBPd_U, WBBPd, or WBBPf is preferentially configured in slot 3.
The following figure shows the typical configuration of BBU boards. Figure 4-7 Typical configuration of BBU boards

In a GU base station, a single BBU is configured with two main control boards, in which one works in GSM mode and the other works in UMTS mode. l The G*U base station is a co-MPT GSM/UMTS dual-mode base station. In a G*U base station, one main control board in a single BBU can work in GSM and UMTS dual-mode.
The following figure shows the BBU slot assignment in a GU base station. Figure 4-10 BBU slot assignment

4 BBU Slot Assignment NOTE
l The baseband processing board in UMTS mode configured in only slot 3 or 2 can be connected CPRI cables. 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 is UBBPd_U, WBBPd, or WBBPf. l If both slots 2 and 3 are occupied by the WBBPa or WBBPb boards, exchange boards to ensure that the UBBPd_U, WBBPd, or WBBPf is configured in slot 3 or 2. The UBBPd_U, WBBPd, or WBBPf is preferentially configured in slot 3. l If two or more baseband boards in GSM mode are required, ensure that at least one of the baseband board (UBBPd_G, UBRI, or UBRIb) is installed in slot 1, slot 2, or slot 3. l The UBBP_G installed in slot 4 can not be connected CPRI cables in a GBTS.

In a GU dual-mode base station where the GTMU is connected to port on the WMPT or UMPT through ports on their panels, part of CPRI bandwidth of UMTS mode is reserved for a TX and an RX channel of GSM mode in case that bandwidths of GSM mode are insufficient. As a result, the number of cells supported by UMTS mode is reduced.

l "Antenna Configuration" lists the maximum configurations supported by various types of a baseband processing board. For example, the LBBPc supports the maximum configuration of 3x10 MHz 4T4R, and therefore supports any of the following configurations: 3x1.4 MHz 4T4R, 3x3 MHz 4T4R, and 3x5 MHz 4T4R. l As long as the maximum antenna configuration is not exceeded, different cells support different antenna configurations. For example, if an LBBPd2 supports the 3x20 MHz 2T2R antenna configuration, the three cells connected to the LBBPc can use the following antenna configurations: 2T2R, 2T2R, and 1T1R. l Boards with the same antenna configuration support combinations of different bandwidth as long as the total bandwidth does not exceed the maximum bandwidth supported by the board. For example, if an LBBPc supports the 3x20 MHz 2T2R antenna configuration, the three cells connected to the LBBPc can use any of the following antenna configurations: 1.4 MHz 2T2R, 3 MHz 2T2R, 5 MHz 2T2R, 10 MHz 2T2R, 15 MHz 2T2R, and 20 MHz 2T2R. l The LBBP supports CPRI convergence when the site is configured with any of the following RF modules: RRU3221, RRU3240, RRU3828, RRU3829, RRU3928, RRU3929, LRFUe, MRFUd, RRU3229, RRU3841, RRU3942, RRU3642, RRU3832, RRU3838, and RRU3268. The CPRI convergence of the LBBP must comply with the following principles: l In LBBPc+LBBPc CPRI convergence mode, the CPRI convergence is allowed only between two LBBPc boards, and one LBBPc board must be configured in slot 2 or 3. l In LBBPc+LBBPc CPRI convergence mode, the CPRI convergence is allowed only from multiple LBBPc boards to one LBBPd board, and only the CPRI ports on the LBBPd in slot 2 or 3 can connect to RF units. l in LTE TDD scenarios, the LBBPc cannot serve as a converging board and only can be a converged board.
