About This Document
This section describes changes in the 3900 Series GSM Base Station Technical Description of each version. 2 Overview 3900 series base stations adopt the cutting-edge modular design for different modes and are managed by various systems. With simple components, they can be installed and deployed easily and fast. With comprehensive functions and remarkable performance, they can meet requirements in various scenarios. In addition, they are diversified by flexibly combining functional modules and auxiliary devices. 3 BTS System Principle The BTS consists of the BBU3900 (BBU for short), RF modules, and the antenna system. Its functional subsystem includes the control system, transport system, monitoring system, RF system, antenna system, and power supply system. 4 Control and Transport Systems The functions of the control and transport systems are provided by the BBU. The control system manages the entire BTS system in a centralized manner, including signaling processing, operation and maintenance, and system clock. The transport system provides physical ports connecting the BTS and the transport network. 5 RF System The functions of the RF system are provided by RF modules including the radio frequency units (RFUs) that are used in macro base stations and remote radio units (RRUs) that are used in distributed base stations. The RF system performs modulation, demodulation, data processing, and combination and division of RF and baseband signals. 6 Antenna System The antenna system consists of antennas, feeders, jumpers, the Tower Mounted Amplifier (TMA), the Bias Tee (BT), and the GSM Antenna and TMA Control Module (GATM). It transmits and receives RF signals. 7 Operation and Maintenance Operation and Maintenance (OM) covers management, monitoring, and maintenance of the software, hardware, and configuration of the BTSs. In addition, diversified OM modes are provided in various scenarios. 8 External Reference Clock Sources The BTS supports multiple external reference clock sources, including the IP reference clock, E1/T1 reference clock, synchronous Ethernet reference clock, BITS reference clock, and GPS/ RGPS reference clock. If a BTS fails to obtain clock signals, it works in free-run mode for a certain period of time. 9 Surge Protection Specifications This section provides surge protection specifications for the BBU, RF modules, and each type of base stations. 10 Technical Specifications This section provides technical specifications for RF modules.

Table 4-2 Usage scenarios and advantages of the four topologies Topology
Usage Scenario
Advantage
Star
A wild range of areas, especially densely populated areas
l Networking is simple. l Engineering is easy. l Maintenance is easy. l Network capacity expansion is easy. l Transmission reliability is high.
Chain
Strip areas that are sparsely populated such as areas along highways and railways
This topology helps reduce expenditure on transmission device, engineering, and leased transmission cables.
Tree
Areas where network architecture, site distribution, and subscriber distribution are complicated such as an area where large-scale coverage overlaps with hot spot areas or small-scale coverage.
Compared with the star topology, this topology requires fewer transmission cables.
Ring
A wild range of areas. Because of its self-healing capability, this topology is recommended when a route is available.
A ring topology can automatically split into two chains if transmission is disrupted at a breakpoint and base stations before and after the breakpoint can still function properly. This improves the system robustness. As shown in Figure 4-3, transmission is disrupted at B. Before disruption, BTSs 0, 1, and 2 are connected in a clockwise direction, forming a ring topology. After disruption, transmission is normal at BTS 0 and BTSs 1 and 2 form a chain topology with BTS 2 being the upperlevel base station.

5.8 Hybrid Configuration of RF Modules This chapter describes the cabinets supported by RFUs and RRUs and principles for hybrid configuration.
RFU Cabinets Supported by RFUs Restrictions for cabinets supported by RFUs are as follows: l
MRFUd and MRFUe must use Ver.C or Ver.D series cabinets.
l
There is no restriction for other RFUs.
Hybrid Configuration Principle In a capacity expansion scenario, use different types of RFUs for hybrid configuration to improve the system capacity or to implement evolution of the network technology type. Table 5-24 lists the RFU hybrid configuration principles. Table 5-24 RFU Hybrid Configuration Principles

In the same sector
RFUs that can be configured together are as follows: l All types of RFUs except DRFUs support hybrid configuration. l When different types of RFUs are used together, you must upgrade the software of the base station, base station controller, and CME to the required version, as shown in Table 5-25. l When an MRFUd is used together with a 1T2R RFU of another type: – The MRFUd does not work with the RFU to achieve the inter-module radio frequency (RF) frequency hopping function. – The MRFUd does not work with the RFU to achieve the dual-PA power sharing function. PA stands for power amplifier. l When a GRFU is used together with an MRFU or MRFUe: – If the MRFU or MRFUe is working in GSM mode, it can work with the GRFU to achieve the inter-module RF frequency hopping and dual-PA power sharing functions. In this case, the MRFUe supports a maximum of 6 carriers, and the difference between the number of carriers on the GRFU and the number of carriers on the MRFUe must not exceed 1. – If the MRFU or MRFUe is working in GU or GL mode, it cannot work with the GRFU to achieve the intermodule RF frequency hopping or dual-PA power sharing function. Take GRFU V2 hybrid configuration as an example, as shown in Figure 5-31.

The BTS is originally configured with GSM S4 x 20 W with each sector configured with one GRFU V2 1800 MHz module. To expand the capacity, one MRFU V2 module is added in each sector. Therefore, the BTS now is configured with GSM S8 x 20 W, and the added MRFU V2 is configured with S4 x 20 W.
RRU Cabinets Supported by RRUs Restrictions for cabinets supported by RRUs are as follows: l
RRU3929 and RRU3942 must use Ver.C or Ver.D series cabinets.
l
There is no restriction for other RRUs.
Hybrid Configuration Principle In a capacity expansion scenario, use different types of RRUs for hybrid configuration to improve the system capacity or to implement evolution of the network technology type.

Antenna System
The antenna system consists of antennas, feeders, jumpers, the Tower Mounted Amplifier (TMA), the Bias Tee (BT), and the GSM Antenna and TMA Control Module (GATM). It transmits and receives RF signals.
Antenna Antennas are used to radiate and receive radio waves. The working principle of antennas is as follows: RF signals output from a radio transmitter are transmitted to antennas over feeders. After receiving the signals, the antennas transmit them to a destination in the form of electromagnetic waves. At the destination, antennas receive the electromagnetic waves, convert them into RF signals, and transmit the signals to a radio transmitter over feeders. A remote control (RC) can control the downtilt of the remote electric tilt (RET) antennas remotely.
Feeders and Jumpers Feeders and jumpers are used to transmit RF signals between antennas and radio transmitters at minimum loss.
TMA The TMA is a low noise amplifier that is installed close to antennas. One end of the TMA is connected to an antenna port on an RF module while the other end is connected to antennas. By amplifying weak signals received by antennas, the TMA helps improve receive sensitivity of the BTS, expand the uplink coverage, and lower transmit power of MSs.
BT The BT couples the On-Off-Keying (OOK) signals or RF signals into the passive components of feeders.
GATM The GATM must be configured if the DRFU, RET antennas, and TMA are configured. Functions of the GATM are as follows: l
Controlling RET antennas.
l
Feeding power to the TMA.

8 External Reference Clock Sources
External Reference Clock Sources
The BTS supports multiple external reference clock sources, including the IP reference clock, E1/T1 reference clock, synchronous Ethernet reference clock, BITS reference clock, and GPS/ RGPS reference clock. If a BTS fails to obtain clock signals, it works in free-run mode for a certain period of time.
IP Reference Clock When a BTS works in IP over FE mode, it obtains clock signals from an IP reference clock. In this case, an IP clock server must be configured. The server sends the User Datagram Protocol (UDP) packets carrying reference clock information to the BTS. After receiving the packets, the BTS interprets clock signals from the packets and then synchronizes its clock system.
E1/T1 Reference Clock The BBU obtains clock signals from an E1/T1 port. Then, the BBU performs frequency division, phase locking, and phase adjustment on the clock module to export 2 MHz and 8 kHz clock signals for bit synchronization and frame synchronization. An E1/T1 reference clock obtains clock signals from the BSC or transport network. The BTS can obtain clock signals from the BSC using an E1/T1 port. If the BTS adopts IP transmission mode but an IP reference clock is unavailable, the BTS uses an E1/T1 port to obtain clock signals from the transport network.
Synchronous Ethernet Reference Clock When the BTS works in IP over FE mode and the transport network supports the synchronous Ethernet reference clock, the BTS obtains Ethernet clock signals from the transport network.
BITS Reference Clock When the BBU is configured with the USCU board, the GTMU board obtains external BITS clock signals from the USCU board.
GPS/RGPS Reference Clock When the BBU is configured with the USCU board, the GTMU board obtains external GPS/ RGPS clock signals from the USCU board. Issue 12 (2012-12-30)

NOTE
l * indicates that the UMTS mode is supported in terms of hardware. l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the MRFU is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the MRFU is located at a height of 4500 m to 6000m. l For the MRFU working in GSM mode, the maximum output power of each carrier on the MRFU is 60 W when the S1 configuration is applied. Note that, if the output power of 60 W is required, the related license must be obtained. l For the MRFU V2 working in GSM mode and operating in the 900 MHz frequency band: after design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the MRFU V2 when the S1, S2, or S3 configuration is used. When the S4, S5, or S6 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the MRFU V2. l For the MRFU V2 working in GSM mode and operating in the 1800 MHz frequency band, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained when the S4, S5, or S6 configuration is used. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the MRFU V2. l 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. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE
l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the MRFUd is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the MRFUd is located at a height of 4500 m to 6000m. l For the MRFUd working in GSM mode: when the S1 or S2 configuration is applied, the maximum output power of each carrier on the MRFUd is 80 W. If the output power of 60 W or 80 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the MRFUd when any of the S1 through S6 configurations is used. When the S7 or S8 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the MRFUd. l 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. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE
l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the MRFUe is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the MRFUe is located at a height of 4500 m to 6000m. l For the MRFUe working in GSM mode: when the S1 configuration is applied, the maximum output power of each carrier on the MRFUe is 80 W; when the S2 configuration is applied, the maximum output power of each carrier on the MRFUe is 60 W. If the output power of 60 W or 80 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the MRFUe when the S1, S2, or S3 configuration is used. When any of the S4 through S8 configurations is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the MRFUe. l 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. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE
l * indicates that the UMTS mode is supported in terms of hardware. l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the RRU3908 is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the RRU3908 is located at a height of 4500 m to 6000m. l For the RRU3908 V2 working in GSM mode and operating in the 900 MHz frequency band: after design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3908 V2 when any of the S1 through S6 configurations is used. When the S7 or S8 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3908 V2. l 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. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE
l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the RRU3928 is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the RRU3928 is located at a height of 4500 m to 6000m. l For the RRU3928 working in GSM mode: after design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3928 when any of the S1 through S6 configurations is used. When the S7 or S8 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3928. l 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. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

NOTE
l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the RRU3929 is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the RRU3929 is located at a height of 4500 m to 6000m. l For the RRU3929 working in GSM mode: when the S1 or S2 configuration is applied, the maximum output power of each carrier on the RRU3929 is 60 W. If the output power of 60 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3929 when any of the S1 through S6 configurations is used. When the S7 or S8 configuration is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3929. l 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. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.

l Power sharing assumes a random distribution of UEs in the cell. l The output power is 1 dB lesser than the standard power when the RRU3942 is located at a height of 3500 m to 4500m; and is 2 dB lesser than the standard power when the RRU3942 is located at a height of 4500 m to 6000m. l For the RRU3942 working in GSM mode: when the S1 or S2 configuration is applied, the maximum output power of each carrier on the RRU3942 is 60 W. If the output power of 60 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3942 when any of the S1 through S6 configurations is used. When the S7 or S8 configurations is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3942. l 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.

NOTE
l Power sharing assumes a random distribution of UEs in the cell. l If an RRU3926 is placed at an altitude of 3500 to 4500 meters, its power reduces by 1 dB. If an RRU3926 is placed at an altitude of 4500 to 6000 meters, its power reduces by 2 dB. l For the RRU3926 working in GSM mode: when the S1 configuration is applied, the maximum output power of each carrier on the RRU3926 is 80 W. If the output power of 60 W or 80 W is required, the related license must be obtained. After design optimization, the 8PSK and GMSK modulation schemes enable the same output power for each carrier on the RRU3926 when the S1, S2, or S3 configuration is used. When any of the S4 through S8 configurations is used, the license controlling the GBFD-118104 Enhanced EDGE Coverage feature must be obtained. Otherwise, the 8PSK and GMSK modulation schemes cannot enable the same output power for each carrier on the RRU3926. l 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. l Before activating the dynamic power sharing feature, enable the DTX and power control functions. In GBSS8.1, the dynamic power sharing feature is mutually exclusive with the GBFD-113201 Concentric Cell, GBFD-114501 Co-BCCH Cell, GBFD-118001 BCCH Dense Frequency Multiplexing, and GBFD-117501 Enhanced Measurement Report (EMR) features. In GBSS9.0 and later versions, the dynamic power sharing feature can be used together with these features. However, the dynamic power sharing feature currently cannot be used together with the GBFD-117002 IBCA (Interference Based Channel Allocation), GBFD-117001 Flex MAIO, GBFD-118701 RAN Sharing, and GBFD-114001 Extended Cell features in GBSS8.1, GBSS9.0, and later versions.
