cluding support for fractional path loss compensa- tion, where the device estimates the uplink path loss based on downlink measurements and sets the transmit power accordingly, and closed-loop power control based on explicit power-control commands provided by the network. In practice, these power-control 646 Chapter 4 commands are determined based on prior measurements of the received uplink power. The main difference with the LTE control is the possibility of beam-based power control. Uplink power control determines the power level for PUSCH, PUCCH, SRS, and PRACH transmissions. The ith PUSCH/PUCCH/SRS/PRACH transmission occasion is defined by slot index Nslot within a frame with system frame number SFN, the first symbol S within the slot, and the number of consecutive symbols L. For a PUSCH transmission on active uplink BWP k of carrier l of serving cell m and parameter set configuration with index j and PUSCH power control adjustment state with index , a UE first calculates a linear value of the transmit power PUSCH(i,j,9d,u). If PUSCH transmission is sched- uled by DCI format 0_1 and when txConfig in PUSCH-Config is set to "codebook", the UE scales the linear value by the ratio of the number of antenna ports with a non-zero PUSCH transmission power to the maximum number of SRS ports supported by the UE in one SRS resource. The UE divides the power equally among the antenna ports on which it transmits PUSCH with non-zero power. The PUSCH transmit power is calculated as follows [8]: where (i,j, qd, denote transmission occasion, parameter set configuration index, reference signal index for the active downlink BWP, and PUSCH power control adjustment state index, respectively. PCMAXIm (i) denotes the maximum permissible UE transmit power for carrier 1, serving cell m, and in PUSCH transmission occasion i.
