1 Introduction Long Term Evolution (LTE) is an evolved telecom standard. It provides various technical

benefits to Evolved Universal Terrestrial Radio Access Network (E-UTRAN), including:

Reduced service delay

Higher user data rates

Increased spectral efficiency

Optimized support for packet services

Improved system capacity and coverage

LTE has flexible bandwidths, enhanced modulation schemes, and effective scheduling. In

addition, LTE allows operators to use both original and new spectral resources to provide data

and voice services.

1.1 Overview

Focusing on customer-oriented innovation, Huawei launches a series of LTE products in its

SingleBTS product portfolio. The LTE frequency division duplex (FDD) 3900 series base

stations (referred to as the 3900 series eNodeBs in this document) fully utilize Huawei

platform resources and use a variety of technologies to meet the challenges of mobile network

development.

The E-UTRAN NodeB (eNodeB) is used for radio access in the LTE system. The eNodeB

mainly performs Radio Resource Management (RRM) functions such as air interface

management, access control, mobility control, and User Equipment (UE) resource allocation.

Multiple eNodeBs constitute an E-UTRAN system.

The innovative design and flexible combinations of basic modules and auxiliary devices

encourage Huawei to diversify 3900 series eNodeB products. Figure 1-1 shows the 3900

series eNodeBs.

1.2 Benefits

Diverse Usage Scenarios and RF Module Types for Different Network Deployment Requirements

Huawei provides two types of radio frequency (RF) modules: radio frequency unit (RFU) and

remote radio unit (RRU), which can be installed based on installation scenarios for macro and

distributed eNodeBs. Each RF module provides at least two TX channels and two RX

channels (2T2R). The modules support main LTE frequency bands and the minimum

requirement of 2x2 uplink and downlink multiple-input multiple-output (MIMO). RRUs that

are designed with 2T4R or 4T4R are adopted to meet the requirement of higher MIMO. RF

modules are also characterized by their support for various bandwidths, great TX power, and

high power amplification efficiency. 3mRRU that supports multi-carrier, multi-mode, and

MIMO is one of the smallest, lightest, and most-efficient RF modules in the industry. Diverse

usage scenarios and RF module types can meet different network deployment requirements of

operators.

SingleRAN Platform to Support Multi-Mode Base Stations and Smooth Network Evolution

As a SingleRAN solution, the 3900 series eNodeBs can share the mature platform with

other base stations, such as the 3900 series base stations working in GSM or UMTS

mode. Equipment of different standards can be installed in the same cabinet. An indoor

cabinet or a BTS3900AL outdoor cabinet supports a maximum of five carriers and three

standards (GSM, UMTS, and LTE).

The 3900 series eNodeBs enable smooth network upgrade by sharing equipment with

other base stations working in the same frequency band according to the

software-defined radio (SDR) technology. This protects the original investment and

reduces the cost of network deployment.

Flexible Installation for Fast Network Deployment with a Low TCO

Flexible installation of the 3900 series eNodeBs simplifies site acquisition and achieves fast

network deployment with a low total cost of ownership (TCO). The BBU a baseband unit, can





3

be installed on an indoor wall or in a standard cabinet. This reduces the installation

investment. The RRU can be mounted onto a pole, tower, or concrete wall. Flexible

installation locations and low space requirements reduce site lease costs. The RRU can also be

installed close to the antenna system to reduce the cost of feeders and power consumption.

2.2 Basic Modules

The 3900 series eNodeBs feature modular design. The three basic module types include the

BBU (a baseband unit), radio frequency unit (RFU), remote radio unit (RRU), and

AAS(Active Antenna System). The BBU and RRUs/RFUs are connected using optical fibers

or cables through common public radio interface (CPRI) ports to transmit CPRI signals.





5

2.2.1 BBU

The BBU (BBU3900 and BBU3910) is a baseband control unit and performs the following

functions:

Centrally manages the entire base station, including operation and maintenance,

signaling processing, and the system clock.

Processes uplink and downlink baseband signals.

Provides physical ports, which are used to connect the base station to the transport

network for information exchange; a maintenance channel, which is used to connect the

BBU to the operation and maintenance center (OMC); CPRI ports for

communication with RF modules; and ports for communication with environment

monitoring devices.

Figure 2-1 shows the slot layout of a BBU.

Figure 2-1 Slot layout of a BBU

NOTE For details about the BBU3900 and BBU3910, see the BBU3900 Description and BBU3910 Description,

respectively.

2.2.2 RFU

An RFU is a radio frequency unit. RFUs modulate and demodulate baseband signals and RF

signals, process data, amplify power, and detect standing waves.

eNodeBs support RFU combination to provide a larger capacity. RFU combination is a

scheme that two RFUs working in the same frequency band are connected to the same LBBP

to serve the same sector. The configuration principles of the RFU combination are as follows:

Two 1T2R or 2T2R RFUs of the same type can be used together.

Two RFUs of different types that equipped with the same number of antennas can be

used together. Only sectors working in the bandwidth of 5 MHz, 10 MHz, 15 MHz, or 20

MHz are supported.

question.

LRFUe and MRFUd modules have the same appearance but can be identified by different

silkscreens.

2.2.3 RRU

An RRU is a remote radio unit. One or more RRUs constitute the RF part of a distributed

eNodeB. RRUs can be installed on a pole, wall, or stand. They can also be installed close to

antennas to shorten the feeder length, reduce feeder loss, and improve system coverage. RRUs

modulate and demodulate baseband signals and RF signals, process data, amplify power, and

detect standing waves.

eNodeBs support RRU combination to provide a larger capacity. RRU combination is a

scheme that two RRUs working in the same frequency band are connected to the same LBBP

to serve the same sector. The configuration principles of the RRU combination are as follows:

2.2.4 AAS

The AAS is a new type of RF module. An AAS module connects to baseband signal

processing boards using CPRI ports and incorporates the functions of RF modules and

conventional antennas, which simplifies site deployment. In addition, an AAS module has

multiple transmit and receive channels and adjusts beams on the vertical and horizontal

planes, which improves radio signal coverage and expands network capacity.

NOTE


2.5 BTS3900A Cabinet

A BTS3900A cabinet consists of an RF cabinet (RFC) and a power cabinet, or of an RF

cabinet and a transmission cabinet.

The RFC is installed outdoors and uses a direct ventilation system. The power cabinet or

transmission cabinet can be stacked on top of the RFC. Together with the RFC, the

power cabinet or transmission cabinet provides the power distribution and surge

protection functions for the BBU and RFUs. An RFC can house a maximum of six

RFUs.

If a 110 V AC or 220 V AC power supply is applied, an APM30H or APM30H (Ver.C)

power cabinet is used and the BBU can be installed inside the power cabinet.

If a 48 V DC power supply is applied, a TMC11H or TMC11H (Ver.C) transmission cabinet is used and the BBU can be installed inside the transmission cabinet.

NOTE BTS3900A cabinets are of two versions: Ver.C, and Ver.D. The BTS3900A (Ver.C) cabinets can be

APM30H (Ver.C) or TMC11H (Ver.C) cabinets. The BTS3900A (Ver.D) cabinets can be APM30H

(Ver.D) or TMC11H (Ver.D) cabinets.

A single BTS3900A (Ver.C) cabinets can house a maximum of 6 RFUs and 1 BBU. A

BTS3900A (Ver.D) can be configured with radio frequency units (RFUs) and remote radio

units (RRUs). A BTS3900A (Ver.D) supports flexible networking and can be easily expanded

or evolved.A single BTS3900A (Ver.D) cabinet can house a maximum of 12 RFUs, 9 RRUs

(6 RRUs for 2 x 60 W, 3 RRUs for 2 x 40 W), and 2 BBUs.

When the RFU and RRU are configured together on BTS3900A (Ver.D), the RFU and RRU

can be configured on the same baseband processing board. If multiple baseband processing

boards are available, it is recommended to configure the RFU and RRU on different baseband

processing boards.

NOTE When BTS3900A (Ver.D) houses RRUs, an extra DCDU inside the cabinet is needed for the RRU power

supply.

The internal structure of a BTS3900A cabinet supporting AC input power is taken as an

example in the following figure. The BTS3900A cabinet supporting 48 V DC input power has the same internal structure as a cabinet supporting AC input power. However, the former

uses different power modules.

2.6 BTS3900AL Cabinet

A BTS3900AL cabinet performs power distribution and surge protection. It consists of BBUs

and RFUs. As a high-integration outdoor site solution, the BTS3900AL cabinet houses a

maximum of 2 BBUs, 9 RFUs, and 9 RRUs to save installation space and ensure smooth

evolution.





20

When the RFU and RRU are configured together on BTS3900AL, the RFU and RRU can be

configured on the same baseband processing board. If multiple baseband processing boards

are available, it is recommended to configure the RFU and RRU on different baseband

processing boards.

NOTE When BTS3900AL houses RRUs, an extra DCDU outside the cabinet is needed for the RRU power

supply.

2.7 DBS3900

The DBS3900 facilitates site acquisition as well as network planning and optimization, and

reduces network deployment time. It enables operators to efficiently deploy a

high-performance LTE network with a low total cost of ownership (TCO) by minimizing

investment in electricity, space, and manpower.

The DBS3900 consists of the BBU and RRUs. The BBU is characterized by its small

footprint, easy installation, and low power consumption. Therefore, the BBU can be easily

installed in a spare space at an existing site. The RRU is also compact and light. It can be

installed close to an antenna to reduce feeder loss and to improve system coverage.





22

NOTE

Cabinets for the DBS3900 are of two versions: Ver.C and Ver.D. The DBS3900 (Ver.C) cabinets can be

APM30H (Ver.C)/TMC11H (Ver.C)/IBBS200D (Ver.C)//IBBS200T (Ver.C)//IBBS700D

(Ver.C)//IBBS700T (Ver.C) cabinets. The DBS3900 (Ver.D) cabinets can be APM30H (Ver.D)/TMC11H

(Ver.D) /IBBS200D (Ver.D)//IBBS200T (Ver.D)//IBBS700D (Ver.D)//IBBS700T (Ver.D) cabinets. If the

cabinet version is not specified, the description is applicable to the cabinet of either version. If the

cabinet version is specified, the description is applicable only to the cabinet of that version.

2.9 LampSite solution

2.9.1 Overview

The LampSite solution provides indoor coverage to indoor areas with high traffic, such as

office buildings, shopping malls, bars, hotels, and parking lots. In the LampSite solution, the

base station comprises the baseband unit (BBU), pico remote radio unit (pRRU), and RRU

HUB (RHUB). These modules can be flexibly combined to meet different scenario

requirements.

Like the DBS3900, the LampSite uses the same type of BBU.

The RHUB3908 and pRRU3901 are compact and light, and therefore they can be installed

anywhere indoors. The RHUB3908, which is 1 U in height, can be installed in a cabinet, rack,

shelf, or on a wall. The pRRU3901 can be installed on a wall or ceiling.

In office buildings, BBUs are installed in an equipment room, and RHUBs and pRRUs are

installed in the office areas, as shown in Figure 2-1.





36

Figure 2-1 Example of the LampSite

In SRAN9.0, if the customer requires the WLAN network deployment in addition to the

UMTS/LTE network, pRRUs with Wi-Fi daughter cards can be purchased and connected to

the WLAN network through GE ports on the pRRUs.





37

2.9.2 Typical Configurations

The following are the configuration principles for the LampSite solution:

UMTS

One RHUB supports one or two independent sectors, and each sector supports one or

two cells.

One BBU supports a maximum of 96 pRRUs.

A cell can be served by a maximum of 96 pRRUs concurrently.

Four-level RHUB cascading is supported on a CPRI link, and the RF combining of a

maximum of 16 pRRUs is supported on this link.

LTE

One RHUB supports a maximum of four independent sectors, and each sector

supports only one cell.

One BBU supports a maximum of 96 pRRUs.

In SRAN9.0 or later, a cell can be served by a maximum of 96 pRRUs concurrently.

In SRAN9.0 or later, four-level RHUB cascading is supported on a CPRI link, and

the RF combining for a maximum of 16 pRRUs is supported on this link. For LTE

cells, one RHUB can serve only one LTE cell that is also served by another RHUB.

Multi-mode

On multi-mode networks, each mode is configured separately.

In the separate-MPT multi-mode scenario, one BBU supports a maximum of 96

pRRUs.

In the co-MPT multi-mode scenario, one BBU supports a maximum of 48 pRRUs.

The typical configurations of the LampSite solution are shown in Table 2-18 and Table 2-19.

The LBBPd1 board is used as an example of the LBBPd board, and the UBBPd3 board is

used as an example of the UBBPd board. The following are the specifications of each

baseband board:

Each WBBPf board supports a maximum of six UTRAN cells.

Each LBBPd1 board supports a maximum of three E-UTRAN cells.

Each UBBPd3 board supports a maximum of six UTRAN cells or three E-UTRAN cells.

The following typical configurations use the maximum configurations of one CPRI link as an

example. The configurations can be flexibly provided as the customer requires.

NOTE

In SRAN9.0 or later:

As listed Table 2-19, the pRRU can connect to the RHUB through one Ethernet cable to carry the CPRI

data. Therefore, one RHUB can connect to a maximum of eight pRRUs. Table 2-20 lists the number of

required Ethernet cables for the LampSite solution in different scenarios.

In the UMTS mode, the WBBPf or UBBPd board can be used as the baseband processing board. In the

LTE mode, the LBBPd or UBBPd board can be used as the baseband board. The UBBPd board is

recommended.

When the UBBP board is used as the baseband board, the board supports only single-mode networks,

not multi-mode networks.

In the preceding tables, combination indicates combination of pRRU cells.

One pRRU has three slots, in which RF daughter boards in different modes can be configured

to achieve flexible multi-mode configurations. Table 2-20 lists the number of required

Ethernet cables for the LampSite solution in different scenarios.
