eLTE2.2 DBS3900 LTE Configuration Principles 2 Application Overview

2 Application Overview The eLTE2.2 DBS3900 (referred to as DBS3900 in this document), one of the eNodeB

products launched by Huawei, is a future-oriented LTE product integrating wireless platform

resources and diverse technologies.

Based on Huawei advanced SingleRAN platform, the DBS3900 consists of two types of basic

function modules: baseband unit (BBU) (referred to as BBU3900 in this document) and

remote radio unit (RRU). The BBU3900 is characterized by its small floor area, easy

installation, and low power consumption. Therefore, the BBU3900 can be easily installed in

the same place as an existing site. The RRU is compact and light. It can be installed near an

antenna to reduce feeder loss and improve system coverage.

Flexible combinations of the basic modules and auxiliary devices provide diverse site

solutions, which can meet customers' requirements for fast network construction.

The DBS3900 supports a scalable bandwidth of 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz,

or 20 MHz to meet operators' requirements for different frequencies.

The maximum configuration supported by the DBS3900 (when the DBS3900 is installed in

an APM30H cabinet equipped with one BBU) is as follows:

Single-carrier

4 x 2 multiple-input multiple-output (MIMO)

6cells @ 1.4/3/5/10/15/20MHz(2T2R RRU)

12cells @ 1.4/3/5/10/15/20MHz(4T4R RRU)

2 x 2 MIMO

12cells @ 1.4/3/5/10/15/20MHz

Dual-carrier

2 x 2 MIMO

18cells @ 1.4/3/5/10/15/20MHz

The DBS3900 serves a maximum of 10,800 RRC connected users when one BBU is

configured.

3 Product Configurations 3.1 Hardware Configurations

3.1.1 Basic Configuration Principles

The DBS3900 consists of the BBU3900 and LTE RRUs.

The following boards and units can be configured in the BBU3900:

Universal main processing and transmission unit (UMPT)

LTE baseband process unit (LBBP): LBBPd1, LBBPd2, and LBBPd3

Universal satellite card and clock unit (USCU)

is not stated. (In this case, the hardware

license for LBBP capacity used for 4T4R is

not required and can be added when evolution to 4T4R is required.)

LBBPd3 2T2R:

6x1.4M/6x3M/6x5M/6x10

M/6x15M/6x20M

The LBBPd3 is recommended for network

capacity expansion when there are three or fewer

cells.

An APM30H (Ver.D) cabinet (AC or DC) can supply power for six RRUs, and can

supply power for 15 RRUs after a direct current distribution unit (DCDU) is added. Among the 15 RRUs, a maximum of 12 high-power RRUs (2 x 60 W) are allowed.

An APM30H (Ver.D) cabinet (AC or DC) can supply power for two BBU3900 modules

if the total power of the two BBUs does not exceed 1000 W.

When the DBS3900 is installed indoors, the BBU3900 can be installed in a 19-inch wide, 2-U

high, and well-ventilated cabinet or rack.

The RRUs can be installed on walls or poles.

The LBBP specifications are as follows:

The LBBP supports a scalable bandwidth of 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, or

20 MHz.

Used with the LBBP, the DBS3900 supports a maximum of 12 cells. The following tables

describe reference configurations.

The configurations in the preceding tables assume that the LRRU is used.

The configurations in the preceding tables are formulated based on the minimum number of LBBP boards, and the impact of the throughput of a single cell or LBBP is not considered.

The maximum number of RRC connected users supported by the DBS3900 equipped with one BBU varies with the selected type of main control board.

If the UMPT is selected, the DBS3900 supports a maximum of 10,800 RRC connected users.

The BBU3900 supports the hybrid configuration of LBBPd1, LBBPd2, and LBBPd3. The number of users supported by a single LBBP is as follows:

One LBBPd1, LBBPd2, or LBBPd3 supports a maximum of 3600 RRC connected users.

Table 3-4 is for your reference only.

An RRC connected user is one in the RRC_CONNECTED state. A scheduled user is one that is in the RRC_CONNECTED state and maintains uplink synchronization. If a scheduled user requires uplink and uplink services, resources can be allocated to the user at any time. RRC connected users include scheduled users.

LTE supports IEEE 1588v2 synchronization. In addition, a GPS satellite card is integrated into the

UMPT to connect to satellite antennas and receive GPS signals.

When GPS signals and Global Navigation Satellite System (GLONASS) signals need to be received, a USCU board must be installed. Two satellite cards are integrated into the USCU board to connect to satellite antennas and receive GPS and GLONASS signals. Each satellite card performs supplementary calculation on signals received on the two channels to improve signal accuracy.

LTE supports AGPS-based precise location when a USCU board equipped with U-Blox satellite cards is configured. AGPS is short for Assisted Global Positioning System.

3.2 RF Module Configurations This section describes the configuration principles for and configuration methods of RF

modules for 3900 series base stations.

3.2.1 RF Module Configuration Principles

RF modules are selected based on frequency bands. At least one RF module needs to be

configured for each sector. RF modules can be configured based on the number of sectors,

number of carriers, and output power.

Table 3-14 describes the configuration relationships between sectors and RF modules. For

details about the frequency bands, number of sectors, number of carriers, and output power

supported by each type of RF module, see the related RF module technical specifications.

This item is configured only for an RF

module that supports more than two

channels in terms of hardware specifications.

Each RF module provides two TX

channels for each cell. One piece is added for every additional TX channel.

Quantity = Number of RRUs requiring

more than two TX channels x (Number

of channels required by one RRU 2)

This item applies only to an RF module that supports four TX channels.

Blade&AAU (per 20W)

This is the

license for the

RF module

power of a

blade RRU or

AAU.

The RF output power of 20 W is

included in the hardware quotation for

each RF module. One piece is added for

every 20 W power used by each RF

module when the output power of the RF

module exceeds 20 W.

This item applies only to the multimode RF modules of blade RRUs or AAUs.

Blade&AAU

(per carrier)

This is the

license for the

RF module of a

blade RRU or

AAU to

support

multiple carriers.

Each RF module provides one carrier by

default. If an RF module uses more than

one carrier, one piece is added for every

carrier used by this RF module.

For MIMO, the power required by a module is calculated by using the following formula:

Power required by a module = Number of MIMO channels of the module x Output power of each channel

2 x 2 MIMO (2 x 30 W): Each RRU requires an output power of 60 W and two licenses for RF output power must be configured.

2 x 2 MIMO (2 x 40 W): Each RRU requires an output power of 80 W and three licenses for RF output power must be configured.

4 x 2 MIMO (4 x 40 W): Two RRUs are required. Each RRU requires an output power of 80 W and three licenses for RF output power must be configured. The BBU3900 supports the LBBPc, LBBPd1, LBBPd2, LBBPd3, UBBPd3, UBBPd4, UBBPd5, and UBBPd6 simultaneously.

5.2 Capacity Expansion Methods and Principles This section describes the methods of and principles for expanding the capacity of 3900 series

base stations. For details, see Table 5-2.

Table 5-2 Capacity expansion methods and principles

Capacity Expansion Method Capacity Expansion Principle

RF capacity expansion If the existing hardware supports the configuration

after the capacity expansion, the capacity can be

expanded by adding multi-carrier licenses and

increasing the power. If the existing hardware does

not support the configuration after the capacity

expansion, the capacity can be expanded by adding

RFUs or RRUs.

Baseband capacity expansion If the existing boards support the configuration after

the capacity expansion, the capacity can be expanded

by adding licenses. If the existing boards do not

support the configuration after the capacity expansion,

the capacity can be expanded by adding LBBP boards.

Transmission capacity expansion If there are more than four E1/T1 electrical ports or

there is more than one FE electrical port or FE optical

port, the capacity of transmission interfaces can be expanded by adding UTRP boards.
