Enhanced EDGE Coverage 2 Overview of Enhanced EDGE Coverage



Ltd.

2-1

2 Overview of Enhanced EDGE Coverage

In a GSM network, CS services and low-rate PS services (in CS1-CS4 or MCS1-MCS4 mode) use the GMSK modulation scheme, and high-rate PS services (in MCS5-MCS9 mode) use the 8PSK modulation scheme.

The peak power in 8PSK modulation scheme is higher than that in GMSK modulation scheme when the average powers are the same. Compared with the maximum output power of the TRX in GMSK modulation scheme, the maximum output power of the TRX in 8PSK modulation scheme is decreased to a fixed extent. Thus, the maximum output power of the DTRX or multi-carrier TRX with high-rate PS services is lower than that of the DTRX or multi-carrier TRX with CS services. As a result, the average power in 8PSK modulation scheme is lower than that in GMSK modulation scheme. The MS receive gain is related to the average transmit power of the BTS. Therefore, the PS services in 8PSK modulation scheme cannot be provided on the edge of a cell, and thus the network performance does not reach the optimum level.

In the existing network, the BSC controls multiple BTSs and manages BTS radio resources, and the BTS handles services. In the case of PS services, the BTS determines whether to use GMSK or 8PSK modulation scheme according to the service type of the BSC. In 8PSK modulation scheme, the maximum transmit power of a TRX is improved through enhanced EDGE coverage so that the maximum output power of high-rate PS services is the same as that of CS services. In this way, the average output power of high-rate PS services in 8PSK modulation scheme is the same as that of CS services.

Regarding DTRX and multi-carrier TRX, enhanced EDGE coverage helps improve the maximum output power of high-rate PS services through different mechanisms. When EDGEPWREN is set to ALLOWED, enhanced EDGE coverage function is allowed to perform.

The maximum output power in 8PSK modulation scheme must not exceed that in GMSK modulation scheme to avoid impacts on network planning.

Enhanced EDGE coverage helps improve network performance in the following ways:

Increasing the network coverage so that the coverage area of high-rate PS services is almost the same as that of CS services.

Increasing the transmit power. The C/I of calls is improved. In this way, a higher-order modulation scheme can be used to increase the uplink and downlink data rate.

Enhanced EDGE coverage is supported by the following BTSs and TRXs:

Double-transceiver series base stations

DTRUs and DTRMs of BTS3012, BTS3012II, BTS3012AE, BTS3006C, and BTS3002E

3900 series base stations

DBS3900, BTS3900, BTS3900A, BTS3900L, and BTS3900E

Neither QTRUs nor BTS3900B supports enhanced EDGE coverage.

Enhanced EDGE Coverage 3 DTRX



Ltd.

3-1

3 DTRX

3.1 Principles

If HIGHMODPWREN is set to ALLOWED, enhanced EDGE coverage is enabled. In this case, the maximum output power of the TRX is increased by the value specified by UPGRADELEV8PSK. If the BCCH TRX is to be enabled with enhanced EDGE coverage, MAINBCCHHIGHMODPWREN should be set to ALLOWED. In this manner, the maximum output power of the BCCH TRX is increased by the value specified by UPGRADELEV8PSK.

For the DTRX, if one of the two carriers that belong to the same cell and DTRX is idle at a transmit moment, then PS services are transmitted by the two carriers at the same time. That is, dynamic transmit diversity or dynamic PBT is used to transmit PS services. In this case, the maximum output power of high-rate PS services can reach to a level as that of CS services when the DTRX is in separated or combined transmit mode.

For details about dynamic transmit diversity, see Transmit Diversity Feature Parameter Description.

For details about dynamic PBT, see PBT Feature Parameter Description.

3.2 Application Scenarios

Enhanced EDGE coverage can be enabled only when the output power of a TRX reaches the maximum value.

Whether each timeslot on TRX A can be enabled with enhanced EDGE coverage depends on the transmission state of the same timeslot on TRX B that is on the same DTRX as TRX A. If the transmission state is disabled, then the timeslots on TRX A can be enabled with enhanced EDGE coverage. If one of the power amplifiers on TRX A and TRX B is power off, then enhanced EDGE coverage cannot be started.

Enhanced EDGE coverage can be enabled only when both the power amplifiers on the two TRXs of a DTRX are power on and the two TRXs belong to the same cell.

For Huawei 3900 series base stations, the implementation modes of enhanced EDGE coverage of a DTRX vary according to the transmit and receive mode, as listed in Table 3-1. The DTRX of 3900 series base stations is categorized into DRRU and DRFU. DRRU and DRFU differ in the following ways:

A DRRU is used in distributed base stations. The transmit and receive mode of a DRRU is specified by SndRcvMode.

A DRFU is used in outdoor and indoor macro base stations. The transmit and receive mode of a DRFU is specified by SndRcvMode1.

Enhanced EDGE Coverage 4 Multi-Carrier TRX



Ltd.

4-1

4 Multi-Carrier TRX

4.1 Principles

If HIGHMODPWREN is set to ALLOWED, enhanced EDGE coverage is enabled. In this case, the maximum output power of the TRX is increased by the value specified by UPGRADELEV8PSK. If the BCCH TRX is to be enabled with enhanced EDGE coverage, MAINBCCHHIGHMODPWREN should be set to ALLOWED and the maximum output power of the BCCH TRX is increased by the value specified by UPGRADELEV8PSK.

For a multi-carrier TRX, output power is shared among multiple TRXs so that the transmit power of TRX in 8PSK modulation scheme is increased. The power amplifier of a multi-carrier TRX does not transmit signals at full power in most cases due to power control or due to no traffic in some timeslots. In this case, power margin exists. If the power margin is used by other 8PSK traffic channels on the same timeslot, the maximum output power of the multi-carrier TRX in 8PSK modulation scheme may reach that of the multi-carrier TRX in GMSK modulation scheme.

4.2 Application Scenarios

Enhanced EDGE coverage can be enabled only when the output power of a TRX reaches the maximum value.

Enhanced EDGE coverage can be enabled if the capability of the power amplifiers on the multi-carrier TRX is greater than the total output power required by the multi-carrier TRX.

After enhanced EDGE coverage is enabled, the total output power of the multi-carrier TRX must be smaller than the capability of the power amplifiers on the multi-carrier TRX.

Enhanced EDGE Coverage 6 Engineering Guidelines



Ltd.

6-1

6 Engineering Guidelines

6.1 DTRX

6.1.1 Cell Configuration S2 or Lower

When a cell is in S2 configuration mode, a BCCH TRX can be enabled with enhanced EDGE coverage, as shown in Figure 6-1. A non-BCCH TRX cannot be enabled with enhanced EDGE coverage because it cannot transmit signals at full power.

Figure 6-1 DTRX with cell configuration S2

When a cell is in S1 configuration mode, one TRX works and another TRX is idle, as shown in Figure 6-2. The power amplifier of the idle TRX is power off out of power saving. Therefore, enhanced EDGE coverage cannot be enabled in this scenario.


When a cell is in S2 or lower configuration mode, one of the TRXs of each DTRX serves a cell, as shown in Figure 6-3. The two TRXs of the same DTRX belong to different cells, and thus dynamic PBT or dynamic transmit diversity cannot be enabled. Therefore, enhanced EDGE coverage cannot be enabled in this scenario.

GSM BSS




Ltd.

6-2

Figure 6-3 DTRX with cell configuration S2 or lower and TRX shared by another cell

6.1.2 Cell Configuration S3

When a cell is in S3 configuration mode and two DTRXs are configured, the two DTRXs serve the cell, as shown in Figure 6-4.

If the BCCH DTRX is configured with only one TRX and the other DTRX is configured with two non-BCCH TRXs, then both the BCCH TRX and non-BCCH TRXs can be enabled with dynamic PBT or dynamic transmit diversity. Thus, enhanced EDGE coverage can be enabled.

If the BCCH DTRX is configured with two TRXs and the other DTRX is configured with one non-BCCH TRX, then only the BCCH TRXs can be enabled with enhanced EDGE coverage because they can be enabled with dynamic PBT or dynamic transmit diversity. The non-BCCH TRX on the BCCH DTRX and the non-BCCH TRX on the other DTRX cannot be enabled with enhanced EDGE coverage because they cannot be enabled with dynamic PBT or dynamic transmit diversity.


When a cell is in S3 configuration mode, two DTRXs are configured and one of them serve two cells, as shown in Figure 6-5.

If the BCCH TRX is configured on a DTRX that is shared by another cell, then the non-BCCH TRXs on the other DTRX can be enabled with dynamic PBT or dynamic transmit diversity, and thus enhanced EDGE coverage can be enabled.

If the BCCH TRX is configured on a DTRX whose two TRXs serve the same cell, the BCCH TRX can be enabled with dynamic PBT or dynamic transmit diversity, and thus enhanced EDGE coverage can

Ltd.

be enabled. Neither the two non-BCCH TRXs can be enabled with dynamic PBT or dynamic transmit diversity. Thus, enhanced EDGE coverage cannot be enabled.

Figure 6-5 DTRX with cell configuration S3 and TRX shared by another cell

6.1.3 Cell Configuration S4 or Higher

When a cell is in S4 or higher configuration mode, the cell needs at least two DTRXs, as shown in Figure 6-6. The TRXs on which the BCCH TRX and non-BCCH TRXs are located can be enabled with dynamic PBT or dynamic transmit diversity. Therefore, the TRXs can be enabled with enhanced EDGE coverage. The non-BCCH TRXs that share a DTRX with BCCH TRXs cannot be enabled with dynamic PBT or dynamic transmit diversity. Therefore, the non-BCCH TRXs cannot be enabled with enhanced EDGE coverage.

Figure 6-6 DTRX with cell configuration S4 or higher

6.2 Multi-Carrier TRX

6.2.1 Cell Configuration S1

When a cell is in S1 configuration mode, a BCCH TRX serves the cell, as shown in Figure 6-7. If the static power (that is determined by POWT and PWRSPNR) of the BCCH TRX equals the maximum power output capability of the TRX, then the BCCH TRX cannot be enabled with enhanced EDGE coverage. If the power type is lower than the maximum power output capability of the BCCH TRX, then the BCCH TRX can be enabled with enhanced EDGE coverage.

Figure 6-7 Multi-carrier TRX with cell configuration S1

6.2.2 Cell Configuration S2 or Higher

When a cell is S2 configuration mode or higher, regarding consistency of TRX coverage within the cell, some TRXs have at least two carriers and some have only one, as shown in Figure 6-8. This means that the power output capability of the TRXs are not utilized to the greatest extent. If the TRXs are configured with two carriers and at least one of them is BCCH carrier, then the BCCH carrier can be enabled with enhanced EDGE coverage. Whether the non-BCCH carrier on the TRX can be enabled with enhanced EDGE coverage depends on the static power (that is determined by POWT and PWRSPNR) of the BCCH carrier and the power output capability of the TRX. If the power output capability of the TRX is greater than the total power of the BCCH carrier and non-BCCH carrier, then the non-BCCH carrier can be enabled with enhanced EDGE coverage. Otherwise, the non-BCCH carrier cannot be enabled with enhanced EDGE coverage.

If the TRX is configured with at least three carriers or the TRX is configured with two non-BCCH carriers, both the BCCH carriers or non-BCCH carriers can be enabled with enhanced EDGE coverage.

power at a step of 0.2 dB. In some scenarios, the losses vary depending on the tributaries where the power is combined, and the power difference before and after the power output is not an integral multiple of 2 dB. As a result, the cabinet-top output power cannot be adjusted at a step of 2 dB, and the TRX output power cannot be consistent with the cabinet-top output power. Therefore, this parameter provides a smaller step that can adjust the cabinet-top output power. If this parameter is set to "Default", it will not be sent to BTSs because some BTSs do not support the power finetune function.
