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
− 4 x 2 MIMO
9cells @ 1.4/3/5/10/15/20MHz(2T2R RRU)
18cells @ 1.4/3/5/10/15/20MHz(4T4R RRU)
− 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

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.
Table 3-4 Number of users per sector (the number of RRC connected users varies with the LBBP capacity when the LBBP supports multiple sectors)

5 MHz 600
10 MHz/15 MHz/20 MHz 1200
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.

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.
