n power control command. The f(0) value is the one given for message 3 transmission power as part of Eq. 12.2. The absolute closed-loop power control type only uses the current transmission power control command from the eNodeB as the new closed-loop power control,f(i), value. The UE transmission power for PUCCH, given by Eq. 12.4 according to [1] (assuming PUCCH transmission), follows the same principle as transmission power for PUSCH: PCMAX,c(i), F_PUCCH(F) (12.4) ATxD(F') + g(i) LTE Key Performance Indicator Optimization where the main parameters are explained below: PCMAX is the configured UE transmit power defined in [2] in subframe i for serving cell c; PO_PUCCH is a parameter composed of the sum of the following: PO_NOMINAL_PUCCH is PO_NOMINAL_PUSCH equivalent for PUCCH and has a typical range of-127to-96dBm; 0_UE_PUCCH is PO_UE_PUSCH equivalent for PUCCH and has a typical range of -8 to 7 dB; PL is the downlink path-loss estimate calculated in the UE for serving cell C in decibels and is calculated as eNodeB-transmitted reference signal transmission power (delivered to the UE in system information block type 2) - RSRP (measured and filtered by UE); AF_PUCCH(F) corresponds to a PUCCH format (F) power relative to PUCCH format 1a, where each PUCCH format (F) refers to all other PUCCH formats: 1, 1b, 2, 2a, 2b and 3) delivered in system information block type 2 by the eNodeB; ATxD(F') is assumed to be 0 indicating no PUCCH transmission from two antenna ports by the UE as defined in [1]; h(nCQI nHARQ' NSR) is a PUCCH format-dependent value explained in [1]; Note that there is no fractional power control for PUCCH, that is, alpha equals 1; The closed part g(i) is adjusted by eNodeB according to the power control strategy. The transmit power control command, SPUCCH, included into the PDCCH format 1,1A, 1B, 1D, 2, 2A, 2B or 2C can have values {-1, 0, 1, 3}. The transmit power control command, SPUCCH, included into the PDCCH format 3 or 3A can have values {-1, 1}. The transmit power control command is included int
