1 Introduction
1.1 Positioning
With the mobile communications technology advancing rapidly, the focus of the mobile
operators during network construction and partner selection rests on innovation and
integration of multiple technologies. This approach helps mobile operators in building a
cost-effective and future-oriented mobile network.
The launch of 3900 series multi-mode base stations effectively drives the development of the
mobile network by presenting a network that adheres to the concepts of "Convergence,
Broadband, Green, and Evolution", thus enabling operators to build an advanced and
future-oriented mobile network.
With the concept of continuous innovation based on customer requirements, Huawei unveils
the 3900 series multi-mode base stations, a future-oriented network solution integrating radio
resources and multiple technologies. The design of 3900 series multi-mode base stations are
based on originality that encompasses the latest chip design, system architecture, Power
Amplifier (PA) technology, and power consumption management.
The 3900 series multi-mode base stations feature the cutting-edge modular design of multiple
modes and forms. The three basic modules of the 3900 series multi-mode base stations are
characterized by small size, high integration, low power consumption, and easy and fast
deployment.
The innovative design and flexible combinations of the functional modules and auxiliary
devices encourage Huawei to diversify multi-mode base station products. In addition,
operators can install modules of different modes in one cabinet to form multiple base station
products adapting to different scenarios. This accelerates introduction of new frequency bands
and radio technologies and effectively addresses the requirements for a multi-mode mobile
network.
The 3900 series multi-mode base stations, based on IP switch and multi-carrier technologies,
support bandwidth of over 100 Mbit/s at transmission ports. This ensures the compatibility
with the growing mobile data services and ensures higher data transmission rates for users.
The optimized hardware and system architecture of the 3900 series multi-mode base stations,
in addition to the innovative technologies for the PA and power consumption management,
enable operators to implement energy saving and emission reduction and to construct a green
communication network through temperature control and green energy utilization.

1.2 Benefits
The 3900 series multi-mode base stations adopt the cutting-edge modular design by
combining multiple modes and using the same types of module for different base station
models. The base stations are applicable to various installation scenarios. This significantly
reduces the network construction costs and Operation Expenditure (OPEX) of operators
related to site acquisition, capacity expansion, and environment protection. In addition, the
base stations enable the construction of a future-oriented network and smooth evolution to the
Long Term Evolution (LTE) system.
Smooth Evolution
The 3900 series multi-mode base stations provide multiple evolution solutions and support
the evolution from GSM to UMTS and further to LTE.
When the 3900 series multi-mode base stations work in GSM mode, they comply with the
ETSI standard and 3GPP MCBTS Class 1 and Class 2 standards. When the 3900 series
multi-mode base stations work in GSM+UMTS or GSM+LTE dual mode, they comply with
the 3GPP MSR standard.
Multi-mode and multi-band application of the BBU3900
Boards of different modes support plug and play. When equipped with boards of
different modes, the BBU3900 can serve any two modes among GSM, UMTS, and LTE
at the same time, thus enabling dual-mode applications. In addition, the BBU3900
supports multiple frequency bands. In this manner, the multi-mode and multi-band
application is available.
Application of the SDR technology in GSM, UMTS, and LTE systems
With the Software Defined Radio (SDR) technology, RF modules can support any type
of dual mode among GSM, UMTS, and LTE through data configuration, thus meeting
operators' requirements.
Installation of GSM/UMTS/LTE RF modules and SDR RF modules in the same cabinet
RF modules serving different modes can be installed in the same cabinet so that the
single mode or any type of dual mode among GSM, UMTS, and LTE is applicable to the
base station. RF modules operating in different frequency bands can also be housed in
the same cabinet. In this way, the multi-mode and multi-band application is available.
The 3900 series multi-mode base stations support the following evolution solutions:
In GSM mode: evolution to GSM Edge Radio Access Network (GERAN) with no
requirement for new types of hardware
In UMTS mode: evolution to HSPA+ (including MIMO and 64 QAM) with no
requirement for new types of hardware
In addition, network algorithms combining GSM and UMTS technologies can improve the
network performance. For example, power sharing of GSM and UMTS carriers. That is, GSM
carriers and UMTS carriers are in the same TX channel. When the traffic between the GSM
and UMTS carriers is not balanced, power sharing can be used to improve the PA efficiency,
thus enhancing the UMTS network performance.

Energy-Saving and Environmentally Friendly Design
The compact and modular design, innovative PA, and power consumption management are
the keys to a green communication network that provides energy saving features and requires
fewer equipment rooms.
The PSU intelligent disabling function allows redundant PSUs to be disabled. Only
required PSUs are enabled according to actual power consumption. In this way, the
working efficiency of the power system is improved and its life cycle is prolonged.
The DBS3900 can control power-on and power-off of boards through software, disabling
of RF channels through software, and voltage adjustment of the power supply to the PA
based on DL load. This allows adjustment of power requirements based on the actual
traffic load, thus reducing power consumption. The fan features the intelligent
temperature control design, which enables automatic temperature adjustment and fan
speed control, thus further reducing power consumption.
The BTS3900/BTS3900A/BTS3900L uses the innovative technology in management of
power amplification and power consumption, thus minimizing the occupancy of
equipment rooms and use of energy resources.
The RF cabinet of the BTS3900A employs direct air control, thus reducing the power
consumption of the base station.
The RRU3908 does not have fans. It works in mute mode. Thus, no acoustic noise is
generated.
Fast Network Deployment Due to the compact design and distributed installation, the DBS3900 frees operators
from the concern about load bearing and leasing of extra installation space.
The distributed installation feature of the DBS3900 simplifies transportation,
configuration, and installation. This helps reduce difficulties for operators in site
acquisition, equipment room construction, equipment transportation, and installation,
thus speeding up network construction.
The cabinet macro base station (macro base station in one or more cabinets), the most
compact type in the industry, takes up a small footprint. The footprint of a BTS3900 is
600 mm x 450 mm, that of a BTS3900A is 600 mm x 480 mm, and that of a BTS3900L
is 600 mm x 450 mm.
Investment Saving In GSM+UMTS dual mode:
− The Abis interface and the Iub interface can share transmission ports, thus reducing
transmission costs.
− The RET antenna can be used. This helps to optimize network coverage performance,
reduce interference, and increase system capacity.
The BBU3900 can be installed on a wall or in a confined space. In addition, the
BBU3900 can be installed in the existing equipment, such as the outdoor equipment,
transmission device, or power supply device, thus saving repeated investment for
operators.
The RRU3908 can be installed close to the antenna, thus decreasing power loss, saving
feeder cost, extending coverage area, and reducing the number of sites.
The networks in different modes share the E1 transmission, IP transmission (through FE
interconnection between the WMPT and the GTMU), and IP over E1 transmission. In

addition, the networks support sharing of the transmission bandwidth, thus reducing
investment in transmission resources.
The UTRP in GSM mode supports transmission port sharing with the UTRP in UMTS
mode, thus improving transmission efficiency and transmission capability.
The networks in different modes share the network management resources and auxiliary
devices, thus lowering the total investment, particularly the cost in maintenance. The
cables are easy to install and maintain, and thus capacity expansion is simplified and the
requirement for OM manpower is lowered.
The external clock sources are shared, including E1/T1 line clock, BITS clock, GPS
clock, IP clock (IEEE 1588 V 2), and synchronized Ethernet clock. In this way,
independent clock source for each mode is not required, thus reducing the investment in
equipment for external clock sources.
When the RRU3908 or MRFU works for any type of dual mode among GSM, UMTS,
and LTE, no external combiner, such as the SASU, is required. That is, signals of
different modes can be transmitted from one antenna port of the RF module at the same
time. This lowers the construction cost and avoids extra combining loss.
The reduced power consumption of the macro base station lowers not only the electricity
expense but also the investment in power supply, backup batteries, TEC coolers, and heat
exchangers.
High Reliability Sharing the unified platform and hardware with Huawei SingleBTSs, the 3900 series
multi-mode base stations feature high stability.
The features of Co-Radio Resource Management (Co-RRM), Co-Transmission Resource
Management (Co-TRM), Co-Operation And Management (Co-OAM), and Co-Radio
Network Plan&Radio Network Optimization (Co-RNP&RNO) are supported, thus
enhancing network performance.
The route backup function is supported when base stations in GSM+UMTS or
GSM+LTE dual mode are interconnected through the FE mode. When the transmission
path in one mode becomes faulty, data transmission can be switched to a path in the
other mode through route backup, thus protecting the Operation and Maintenance (OM)
and service data of high priority.
Complying with the ETSI standard, one RF module can reach a maximum of 80 W
output power, with each module supporting six TRXs.
In UMTS mode, the base station enhances its reliability in the following ways:
− Each RF module has two CPRI ports that can be used to form a ring topology
between the RF modules and the BBU3900. In this way, a backup channel between
the BBU3900 and the RF modules is provided, and thus network reliability is
enhanced.
− The baseband processing board supports the resource pool design.
The hierarchical power-off can be supported to reduce the system power consumption
and extend the backup battery time.
The priority-based GSM/UMTS combined intelligent power-off is supported. When
power supply is insufficient, network coverage and service providing time are extended.
The CPRI ports of WBBP and LBBP support 1+1 backup.
The BBU3900 supports 1+1 backup of power input.

2.5 Power Sharing
When the BTS downlink power control is enabled, the total output power of carriers in a cell
is always equal to or less than “Maximum Output Power of Carrier x Number of Carriers”.
Based on the estimated power that calls need, if the calls with different power are grouped
into different timeslots according to a specific rule, the probability that the total output power
of carriers in the cell is less than “Maximum Output Power of Carrier x Number of Carriers”
is further increased. In addition, the total output power of carriers in the cell is far less than
“Maximum Output Power of Carrier x Number of Carriers”. Therefore, each carrier can carry
more power than the standard configuration.
The LTE bandwidth can be 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, or 20 MHz. 2T2R for 1
RRU3908, and 1T2R for 1 MRFU are supported.
The GSM power is measured when the modulation scheme is GMSK. If the modulation scheme is
8PSK, the output power is 1.8 dB less than that in GMSK mode.
Only RRU3908 V2 modules support the V2 specifications.
Only MRFU V2 modules support the V2 specifications.
The RRU3908 at 1800 MHz supports the LTE mode in terms of hardware.
The MRFU at 1800 MHz supports the LTE mode in terms of hardware.
*: The UMTS mode is supported in terms of hardware.
When RRU3908 is located in the area at an altitude of 3500 m to 4500 m, the output power back-off
is 1 dB. When RRU3908 is located in the area at an altitude of 4500 m to 6000 m, the output power
back-off is 2 dB.
When MRFU is located in the area at an altitude of 3500 m to 4500 m, the output power back-off is
1 dB. When MRFU is located in the area at an altitude of 4500 m to 6000 m, the output power
back-off is 2 dB.
Factors such as the site-to-site distance, frequency-reuse factor, power control algorithm, and traffic
model affect the gain achieved by dynamic power allocation. Therefore, in most cases, the network
planning can be based on the power specification achieved by dynamic power allocation.
Power sharing cannot be used together with RAN sharing with BSS and RAN, concentric cell,
Co-BCCH, and IBCA.
In power sharing mode, the power control and DTX should be set to ON.
Output power with power sharing assumes a random distribution of UEs in the cell.

900MHz/850MHz/1800MHz/1900MHz in compliance with the specifications for
