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 the mobile operators in constructing a cost-effective and future-oriented mobile network.
The launch of the 3900 series multi-mode base stations effectively drives the development of the mobile network, presenting a network with concepts of "Convergence, Broadband, Green, and Evolution" and aiding operators in constructing a better future-oriented mobile network.
Upholding 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 the 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 function modules and auxiliary devices encourage Huawei to diversify multi-mode base station products. Furthermore, 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 OPEX of operators in terms of 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.
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 application. 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 SDR technology, RF modules can support any type of dual-mode among GSM, UMTS, and LTE through data configuration, so as to meet 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:
GSM: evolution to GSM Edge Radio Access Network (GERAN) with no requirement for new types of hardware
UMTS: evolution to HSPA+ (including MIMO and 64 QAM) with no requirement for new types of hardware
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 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 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 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 and thus speed 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, whereas that of a BTS3900A is 600 mm x 480 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, so as to save operators' investment.
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 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 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.
When the GSM network uses E1/T1 transport and UMTS uses IP transport, the UMTS network can use the GSM clock, thus implementing clock source sharing without additional investment in the Global Positioning System (GPS) equipment or clock server.
The base station supports clock over IP and does not require GPS for the IP-based base station, thus saving investment.
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 fourth-generation base stations,
the 3900 series multi-mode base stations feature high stability. In UMTS mode, the base station enhances its reliability in the following ways:
− Each RRU3908 or MRFU has two CPRI ports that can be used to form a ring topology between the RRU3908s/MRFUs and the BBU3900. In this way, a backup channel between the BBU3900 and the RRU3908s/MRFUs is provided, and thus network reliability is enhanced.
− The baseband processing board supports the resource pool design. The power-off can be supported to reduce the system power consumption and extend the
backup battery time. The CPRI ports of WBBP support 1+1 backup. The BBU3900 supports 1+1 backup of power input

2.3.3 Typical Configuration of RRU3908
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. The RRU3908 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.
Table 2-7 lists the typical configurations of the RRU3908 V1 at 900MHz/850MHz/1800MHz/1900MHz in compliance with the specifications for multi-carrier base station (Class 2) in 3GPP TS 45.005 V9.0.0.

2.4.3 Typical Configuration of MRFU
Only MRFU V2 modules support the V2 specifications. The MRFU at 1800 MHz supports the LTE mode in terms of hardware. *: The UMTS mode is supported in terms of hardware. 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. 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.

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 × 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 certain rule, the probability that the total output power of carriers in the cell is less than “Maximum Output Power of Carrier × Number of Carriers” is further increased. Or even, the total output power of carriers in the cell is far less than “Maximum Output Power of Carrier × Number of Carriers”. Hence, each carrier can carry more power than standard configuration.

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.
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.
