3 Working Principle and Function of a BBU

Working Principle and Function of a BBU

A BBU is a baseband processing unit. It processes baseband signals of a base station.

Working Principle A BBU consists of the following subsystems: baseband subsystem, power and mechanical subsystem, transmission subsystem, interconnection subsystem, main control subsystem, monitoring subsystem, and clock subsystem. Each subsystem consists of different modules. l

The baseband subsystem consists of the baseband processing unit.

l

The power and mechanical 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 unita as well as 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.

Issue 08 (2015-10-30)

3 Working Principle and Function of a BBU

Figure 3-1 Working principle of a BBU

Function A BBU performs the following functions: l

Provides ports for connecting to the transmission equipment, RF modules, USB devicesa, external reference clock, and LMT or U2000 to transmit signals, perform automatic software upgrade, receive reference clock, and support BBU maintenance on the LMT 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 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.

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.

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 bandwidth of GSM mode is insufficient. As a result, the number of cells supported by UMTS mode is reduced.

NOTE

l The "Antenna Configuration" column lists the maximum configurations supported by various types of baseband processing boards. A baseband processing board supports the maximum configurations and any configurations that do not exceed the maximum configurations. For example, an 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 An LBBP supports combinations of different bandwidths as long as the total bandwidth does not exceed the maximum bandwidth supported by the LBBP. For example, an LBBPc supports the maximum configuration of 3x20 MHz 2T2R, and therefore supports any three of the following configurations: 1.4 MHz 2T2R, 3 MHz 2T2R, 5 MHz 2T2R, 10 MHz 2T2R, 15 MHz 2T2R, and 20 MHz 2T2R. l An 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 LBBP boards 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+LBBPd 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 modules.

l In LTE TDD scenarios, an LBBPc cannot serve as a converging board and only can serve as a converged board.

6.9 UPEU A universal power and environment interface unit (UPEU) is a power module in a BBU3900 or BBU3910. A UPEUd can be installed in a BBU3900 or BBU3910, but other types of UPEU boards can be installed only in a BBU3900.

NOTE

l 1+1 redundancy backup mode: When the power requirement of the BBU does not exceed the maximum power provided by a single UPEU, the two UPEU boards work in 1+1 backup mode and only one UPEU is working at a time. l Current equalization mode: Only the UPEUc supports this mode. When the power requirement of the BBU exceeds the maximum power provided by a single UPEUc, both UPEUc boards provide power output. l A BBU cannot house two UPEU boards of different types. When the power required by the BBU exceeds the power specifications of the BBU: l

If the BBU has been configured with one or two UPEUa boards, replace the boards with two UPEUc boards.

l

If the BBU has been configured with one UPEUc board, add a UPEUc board.

Panel Figure 6-36, Figure 6-37, Figure 6-38, and Figure 6-39 show the four types of UPEU boards. NOTE

l A UPEUc and a UPEUd have silkscreens UPEUc and UPEUd indicating their board types on them, respectively, whereas a UPEUa and a UPEUb do not have such silkscreens indicating their board types. A UPEUa and a UPEUb, however, can be distinguished by the silkscreens -48V and +24V on them. l The silkscreen above the power port is in the "A; B" format, for example, "-48 V; 8 A". A indicates the rated voltage and B indicates the rated current.
