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

SRAN5.0

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 Architecture

2.1 Overview

The 3900 series multi-mode base stations feature a modular design. The BBU3900 and the RF

module (MRFU/RRU3908) are connected through CPRI ports by using an electrical or

optical cable for CPRI signal transmission, thus meeting the requirements of radio network

deployment.

The basic modules of the 3900 series multi-mode base stations are the baseband unit

BBU3900, the outdoor remote radio unit RRU3908, and the RF module MRFU.

The connection between the BBU3900 and the RRU3908 or MRFU adopts the dual-star

topology. That is, the CPRI port on the GTMU is connected to the CPRI_W port on the

RRU3908 or the CPRI_0 port on the MRFU, and the CPRI port on the WBBP or LBBP is

connected to the CPRI_E port on the RRU3908 or the CPRI_1 port on the MRFU.

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.



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.


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.

Table 2-15 lists the typical configurations of the RRU3908 V1 at

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

3 Products and Application Scenarios

3.1 Overview

Flexible combinations of the basic modules and auxiliary devices can provide comprehensive

solutions that are applicable to specific scenarios of operators, such as indoor centralized

installation, outdoor centralized installation, outdoor distributed installation, or co-siting of

base stations in different modes.

Diverse combinations of the basic modules and auxiliary devices form the following products

that are applied to different scenarios, thus meeting requirements for fast and cost-effective

network deployment:

Macro base station in one or more cabinets

− Indoor model: BTS3900, BTS3900L

− Outdoor model: BTS3900A

The cabinet macro base station is installed with the BBU3900 and MRFUs in centralized

mode. The cabinet macro base station is applicable to a centralized installation scenario.

The BTS3900 and BTS3900L are used for the indoor centralized installation scenario,

and the BTS3900A is used for the outdoor centralized installation scenario.

Distributed base station

The distributed base station, that is, the DBS3900, consists of the BBU3900 and the

RRU3908. In a distributed installation scenario, the RRU3908 can be installed close to

the antenna to reduce feeder loss and improve the performance of the base station.

SRAN5.0

3.2 Application Scenarios

3.2.1 Application Scenarios of the DBS3900

As environmental concern and lease cost increases, site acquisition for base stations has

become a bottleneck during network construction, rendering it increasingly difficult to

construct new sites. The DBS3900 developed by Huawei features high integration, easy

installation, and low environment requirements. All these features can facilitate site

acquisition and 2G/3G co-siting.

With these features, the DBS3900 fully addresses operators' concern over site acquisition,

facilitates network planning and optimization, and reduces network construction time. Thus,

the DBS3900 enables operators to efficiently deploy a high-performance GSM/UMTS/LTE

network with a low Total Cost of Ownership (TCO) by minimizing the investment in

electricity, space, and manpower.

Typical Installation Scenarios of the DBS3900

The BBU3900 can be installed in a 19 inch-wide and 2 U-high confined space, such as on a

wall, on the staircase, in the storeroom, or in an outdoor cabinet on the existing network. The

RRU3908 has a wide variety of installation options, such as installation on a pole, wall, or

stand.

Figure 3-1 shows the typical installation scenarios of the DBS3900.

Figure 3-1 Typical installation scenarios of the DBS3900

When 220 V AC input power or +24 V DC input power is available in a new DBS3900

outdoor site and a new power supply system is required, the BBU+APM+RRU

configurations can be used.

When –48 V DC input power is available in a new DBS3900 outdoor site and a new

power supply system is required, the BBU+TMC+RRU configurations can be used.

When 220 V AC input power is available in a new DBS3900 indoor site and a new

power supply system is required, the BBU+PS4890+RRU configurations can be used.

When –48 V DC input power is available in a new DBS3900 indoor site and the BBU

can be installed on the indoor wall, the BBU on the wall+RRU configurations can be

used.

When RRUs are required to be installed in a centralized mode in a new DBS3900 indoor

site, the L-shaped stand can be used.
