Logic Structure of BBU3900

The BBU3900 consists of four logical subsystems: control,

transport, baseband, and power and environment

monitoring


LMPT (The LTE Main Processing & Transmission Unit )

Mandatory, Maximum 2 board, hold in slot 7(default)

or 6

Function:

Performs configuration management, equipment

management, performance monitoring, signaling

processing, and radio resource management

Controls all boards in the system

Provides the system clock and transmission ports


LBBP (The LTE Baseband Processing Unit)

Mandatory, Maximum 3 boards, hold in slot 1(default),2 or

3

Function: Processes uplink and downlink baseband signals

Provides CPRI ports for communication between BBU3900

and RRUs

The LBBPc can be used in both FDD LTE and TDD LTE modes, and the

LBBPb can be used in only FDD LTE mode

FAN

Mandatory, Maximum 1 module

The FAN unit has two types, FAN and

FANc, FANc is adopted in high power

consumption mode

Function:

Monitors the temperature and

Dissipates heat for boards and

modules of the BBU3900

Controls the fan speed and reports the

status of fans to the LMPT


UPEU (The Universal Power and Environment interface Unit)

Mandatory, Maximum 2 modules, hold in slot 4

(default) and slot 5

Functions: Converts -48 V DC or +24 V DC power into +12 V DC

power

Provides ports for transmission of two RS485 signals

and eight dry contact signals


UEIU(The Universal Environment Interface Unit )

UEIU is the environment interface board of

BBU， it can support multi-route monitoring

signal input

UEIU is optional and is only used when more

ports are needed

UTRP (The Universal Transmission Processing unit )

Optional, maximum 2 modules

The UTRP performs the following functions:

Provides ports for eight E1s/T1s based on the IP

protocol.

Deframes and frames of the HDLC, and allocates and

controls 256 HDLC timeslots.


USCU (The Universal Satellite card and Clock Unit )

The USCU performs the following functions:

The USCU provides interface for an external RGPS device

(such as a reused device of the operator), BITS device, and

TOD input

The USCUb0 does not provide the satellite card

The USCUb2 supports GPS and GLONASS with two built-in

satellite cards

USCUb0 Board USCUb2 Board


Clock Synchronization Modes GPS Clock

If an eNodeB is synchronized with the GPS clock, the eNodeB obtains

clock synchronization signals from the GPS through the USCU. In this

case, both frequency synchronization and time synchronization are

applicable

IEEE1588 V2 Clock IEEE1588 defines the Precision Time Protocol (PTP), which targets

precise synchronization of distributed and independent clocks in

measurement and control systems, with the precision to

microseconds. IEEE1588 V2 supports frequency synchronization and

time synchronization

In LTE applications, high-accuracy frequency synchronization and

time synchronization can be achieved between clock servers and

eNodeBs by IEEE1588 V2 synchronization


Clock Synchronization Modes (Cont.) Clock over IP

Clock over IP is a Huawei proprietary frequency synchronization technology, which is based on an IP clock server/client architecture. It supports only frequency synchronization

Free Running The clock enters the free running mode if no reference clock is available after

the oscillator is warmed up or if the clock has lost its reference input for a period of time longer than the timer of the holdover mode

1 PPS The eNodeB obtains 1 Pulse Per Second (PPS) signals to achieve time

synchronization

E1/T1 Line Clock An eNodeB can extract frequency synchronization signals from E1/T1 links at

the physical layer. If S1 data is transmitted over an E1/T1 network, the eNodeB can be synchronized with the E1/T1 line clock
