8.8 Power control in downlink
25.1013GPPRelease 17TSUser Equipment (UE) radio transmission and reception (FDD)
Power control in the downlink is the ability of the UE receiver to converge to required link quality set by the network while using as low power as possible in downlink . If a BLER target has been assigned to a DCCH (See Annex A.3), then it has to be such that outer loop is based on DTCH and not on DCCH.
The requirements in this subclause were derived with the assumption that the UTRAN responds immediately to the uplink TPC commands by adjusting the power of the first pilot field of the DL DPCCH that commences after end of the received TPC command.
8.8.1 Power control in the downlink, constant BLER target
8.8.1.1 Minimum requirements
For the parameters specified in Table 8.29 the downlink 
power ratio measured values, which are averaged over one slot, shall be below the specified value in Table 8.30 more than 90% of the time. BLER shall be as shown in Table 8.30. If the UE supports optional enhanced performance requirements type1 for DCH then for the parameters specified in Table 8.30A the downlink 
power ratio measured values, which are averaged over one slot, shall be below the specified value in Table 8.30B more than 90% of the time. BLER shall be as shown in Table 8.30B and Test 2 shall be replaced by Test 2a. Power control in downlink is ON during the test.

Power control is ON during the test. If the UE supports optional enhanced performance requirements type1 for DCH, Test 1, Test 2, Test 3 and Test 4 shall be replaced by Test 1a, Test 2a, Test 3a and Test 4a.
The first 10 ms shall not be used for averaging, ie the first sample to be input to the averaging filter is at the beginning of T1. The averaging shall be performed with a sliding rectangular window averaging filter. The window size of the averaging filter is linearly increased from 0 up to 50 ms during the first 50 ms of T1, and then kept equal to 50ms.

8.8.4.1 Minimum requirements
Test 1 verifies that UE outer loop power control has proper behaviour with different transport formats.
The downlink reference measurement channel used in this subclause shall have two different transport formats. The different transport formats of the downlink reference measurement channel used shall correspond to the measurement channels specified in Annex A.3.0 and A.3.1. The transport format used in downlink reference measurement channel during different stages of the test shall be set according to the information data rates specified in Table 8.34A. During stage 1 a downlink transport format combination using the 12.2kbps information data rate DTCH shall be used, and during stage 2 the downlink transport format combination shall be changed such that a 0kbps information data rate transport format combination is then used.
For the parameters specified in Table 8.34A the downlink 
power ratio measured values, which are averaged over one slot, shall be below the specified value in Table 8.34B more than 90% of the time. BLER shall be as shown in Table 8.34B. Power control in downlink is ON during the test.

8.8.4A Power control in the downlink, different transport formats
8.8.4A.1 Minimum requirements
Test 1 verifies that UE outer loop power control has proper behaviour with different transport formats.
The downlink reference measurement channel used in this subclause shall have two different transport formats. The different transport formats of the downlink reference measurement channel used shall correspond to the measurement channels specified in Annex A.3A.0 and A.3A.2. The transport format used in downlink reference measurement channel during different stages of the test shall be set according to the information data rates specified in Table 8.34BA. During stage 1 a downlink transport format combination using the 12.2kbps information data rate DTCH shall be used, and during stage 2 the downlink transport format combination shall be changed such that a 0kbps information data rate transport format combination is then used.
For the parameters specified in Table 8.34BA, the downlink 
power ratio measured values, which are averaged over one slot, shall be below the specified value in Table 8.34BB, Table 8.34BC, Table 8.34BD and Table 8.34BE more than 90% of the time. BLER shall be as shown in Table 8.34BB, Table 8.34BC, Table 8.34BD and Table 8.34BE. Power control in downlink is ON during the test. Test requirements in Table 8.34BB, Table 8.34BC, Table 8.34BD and Table 8.34BE correspond to DL_DCH_FET_Config is set to 0 with UL in 20ms transmission mode, DL_DCH_FET_Config is set to 0 with UL in 10ms transmission mode, DL_DCH_FET_Config is set to 1 with UL in 10ms transmission mode and non-Null transmission in the UL, and, DL_DCH_FET_Config is set to 1 with UL in 10ms transmission mode and Null transmission in the UL respectively.
