Antenna System 2 Connection with TMA



2-1

2 Connection with TMA

This section describes the RF RX channel attenuation configuration, power supply configuration, andworking status monitoring configuration of the Tower Mounted Amplifier (TMA).

The connection with TMA function corresponds to the feature MRFD-210601 Connection with TMA(Tower Mounted Amplifier).

2.1 Overview of Connection with TMA

Installed on the tower top, a TMA is a device for amplifying uplink signals. As an optional component ofthe antenna system, the TMA compensates for the feeder loss caused by a long feeder to improve theuplink sensitivity and converge. In SRAN5.0, both NodeBs and BTSs support TMA and smart TMA(STMA). An STMA has a built-in Smart Bias Tee (SBT) in comparison to a TMA. The power supplyswitch and attenuation factor need to be set for both TMA and STMA.

In a network whose uplink coverage is limited, the TMA can be installed to improve the RX sensitivity

and expand the cell radius, thus reducing the number of BTSs and minimizing investments. Users needto determine whether to install the TMA according to the actual project requirements.

BTSs power and control the TMA. Huawei BTS provides the TMA with 10 - 13 V output voltage. When amajor alarm related to the TMA is reported, the BTS automatically sets the attenuation value of the RXchannel to 0.After the alarm is cleared, the BTS automatically restores the attenuation value of the RXchannel to the configured value.The RET control signals, power supply, and RF signals of the TMA are transmitted through the feeder.This facilitates operation and maintenance. The SBT powers the TMA through the feeder and providesthe RCU with control signals.

Huawei BTS also supports dual-TMA. Dual-TMA indicates that each TMA contains two pairs of RX/TXbranches. Each sector needs to be configured with only one TMA. Each TMA also contains a low noiseamplifier (LNA) for monitoring alarms.

The functions of the two pairs of RX/TX branches of a TMA are the same. The RX channel has two RXfilters and one LNA. When the input DC is faulty, the LNA is automatically ignored. The Bias Tee isconfigured on the BTS side of the TMA. The Bias Tee of a smart TMA (STMA) is referred to as an SBT.The Bias Tee can distinguish the combined signals of RF signals and DC signals, power the LNA, andprovide the RCU with RET control signals. The TX channel contains a TX filter, as shown inFigure 2-1.

2.2 RF Receiver Channel Attenuation

The TMA can improve both the uplink RX gain and the RX sensitivity. When the BTS measures theuplink RX level, the measurement result must reflect the actual radio environment. Therefore, the TMAgain must be compensated reversely on the RF RX channel to ensure that the RX quality is improvedand the RX level reflects the actual radio environment when the BTS measures the uplink RX level.

When the TMA is configured, users need to set the RF RX channel attenuation of the RF antennainterface and the RX channel corresponding to the TRX to obtain the TMA gain according to the actualrequirement.

For the BTS, you can run the MML command SET BTSRXUBPto specify whether the TMA is installedon the antenna system, and set the attenuation factor for the TMA.

For the NodeB, you can run the MML command ADD ALDto add the TMA for the antenna line device(ALD), run the MML command SET TMAMODEto set the work mode of the TMA, run the MMLcommand SET TMAGAINto set the gain of the TMA, and run the MML command SET RXATTENto setthe attenuation of the RX channel.

2.3 Power Supply for TMA

The TMA needs to be powered by the BTS/NodeB through the RF feeder:

For the BTS, RXU board types such as the RRU3008, RRU3908, GRFU, and MRFU can directlyprovide power for the TMA. The DRFU, however, does not directly provide power for the TMA. Instead,it needs to be installed with a GATM board to provide power for the TMA. You can run the MMLcommand SET BTSRXUBP/SET BTSDATUBPto enable the power switch.

For the NodeB, the RF module provides power for the TMA. You can run the MML command SETALDPWRSWto enable the power switch.

2.4 Monitor TMA

The working status of the TMA can be determined according to the status of the feeding current on the

TMA. The methods of reflecting the working status of the TMA through the feeding current vary

according to TMAs. Users need to configure feeder boards for TMAs according to the actual TMAfeature configuration.

There are three alarm modes: MODE1 has only one type of alarm whose alarm severity is critical, andthe alarm current threshold is fixed and greater than the normal working current; MODE2 has two types

of alarms whose alarm severities are critical and warning, and the alarm current is fixed and greater thanthe normal working current; MODE 3 has two types of alarms whose alarm severities are critical andwarning, and the warning alarm current is periodical pulse current, while the critical alarm current isfixed.

When the power switch is set to ON, you need to set the current alarm threshold:

For the BTS, you can run the MML command SET BTSRXUBP/SET BTSDATUBPto set the currentalarm threshold.

For the NodeB, you can run the MML command SET ALDPWRSWto set the current alarm threshold.

Antenna System 3 Remote Electrical Tilt



3-1

3 Remote Electrical Tilt

This section describes a solution for remote adjustment of the antenna tilt.

The remote electrical tilt (RET) function corresponds to the feature MRFD-210602 Remote Electrical Tilt.

3.1 Overview of Remote Electrical Tilt

The RET refers to an antenna system whose tilt is controlled electrically. After an antenna is installed,the tilt of the antenna needs to be adjusted for the purpose of network optimization. With the RET feature,the phases of signals that reach the elements of the array antenna can be adjusted through electricalcontrol, so as to change the vertical pattern of the antenna.

The tilt of the RET antenna can be adjusted after the system is powered on and be monitored in real time.In this way, precise adjustment of the antenna tilt can be achieved.

The RET feature provides the following benefits:

The RET antennas at more than one site can be remotely adjusted at the same time. Therefore, theefficiency of adjusting the antenna tilt is improved and the cost of network optimization is reduced.

The adjustment of RET antennas can be performed irrespective of weather conditions.

It is easy to adjust the RET antennas at the sites that are difficult to reach.

The operating principles of RET are described in this chapter.

3.2 Operating Principles of RET

The tilt of the RET antenna can be adjusted remotely.

The phase shifter of the antenna can be controlled by the stepper motor outside or insidethe antenna.

You can adjust the antenna tilt after the system is powered on and monitor the tilt in real time. Therefore,the precise remote adjustment of the antenna tilt can be achieved.

Figure 3-1shows the operating principles of the RET antenna.

(DC+ control signals)

The Remote Control Unit (RCU) is the driving motor of the phase shifter of the RET antenna. The RCUreceives and executes the control commands from the MBTS to drive the stepper motor. A pulling barconnects the stepper motor and the phase shifter. When the stepper motor is triggered, the pulling barmoves and then the phase of the phase shifter changes through the gears. In this situation, the phase ofeach element of the array antenna changes regularly. Then, the direction of the main beam of theantenna changes accordingly. Thus, the antenna tilt is adjusted.

3.3 Operating Principles of Huawei RET

Huawei MBTS supports the following types of RET antenna connection:

Directly connect the RET through multicore cables: It is applicable when the distance between theRRU and the RCU is shorter than 20 meters.

The MBTS supplies the DC power to the stepper motor and communicates with it through the AISGinterface on the motor.

In the Huawei RET solution, the RET antenna can be controlled remotely or locally through a commandsent from the M2000 or LMT respectively.

When directly connect the RET through multicore cables, the process of RET antenna control is asfollows:

1. The M2000 or LMT issues the control command to the BBU, and then the BBU sends the commandto the RRU.

2. The RRU modulates the control command into RS485 signals and then transmits the signals from theRS485 port to the RCU through the control cable.

When connect the RET via the SBT, the process of RET antenna control is as follows:

1. The M2000 or LMT issues the control command to the BBU, and then the BBU sends the commandto the RRU.

2. The RRU modulates the control command into On-Off-Keying (OOK) signals and then transmits the

signals and the DC power from the RF port to the SBT.


16/37

SingleRAN

3. The SBT demodulates the OOK signals into RS485 signals and then transmits the signals and part ofthe DC power to the RCU.

When conect the RET together with STMA, the process of RET antenna control is as follows:

1. The M2000 or LMT issues the control command to the BBU, and then the BBU sends the command

to the RRU.2. The RRU modulates the control command into OOK signals and then transmits the signals and the

DC power from the RF port to the STMA.

3. The STMA demodulates the OOK signals into RS485 signals and then transmits the signals and partof the DC power to the RCU.

The Huawei RET solution supports the RET cascading control. Several cascaded RET antennas can becontrolled by the signals coming from the same control cable. The cascading solution helps save thecost of the SBTs.

The Huawei RET solution also supports the 2G/3G RET cascading control. 3G RET antennas can becascaded with 2G RET antennas. When they are cascaded, the tilts of the 2G RET antennas can becontrolled on the OMC for 3G, and the tilts of the 3G RET antennas can also be controlled on the OMCfor 2G. The cascading helps save the cost of SBTs and STMAs when the 2G and 3G RET antennas areinstalled at the same place.

4 2-Way Antenna Receive Diversity

The 2-way antenna receive diversity function corresponds to the feature MRFD-210604 2-Way AntennaReceive Diversity.

With this feature, the same signal is received by two antennas. Then, the two ways of signals on the twoantennas are combined after being processed. In this manner, the signal attenuation is reduced.

This feature is a technique for improving the receive sensitivity and uplink coverage, thus reducing theCAPEX.
