[ 21. A method for a user equipment (UE) to determine power for signal transmission, the method comprising:
receiving first information about a first configuration for a first set of parameters associated with transmission of a sounding reference signal (SRS) and second information about a second configuration for a second set of parameters associated with transmission of a physical uplink shared channel (PUSCH);
receiving at least one of a first downlink control information (DCI) format associated with a first power control for an SRS transmission or a second DCI format associated with a second power control for a PUSCH transmission;
performing the first power control for the SRS transmission using the first set of parameters and a first transmission power control (TPC) command in the first DCI format, in case that the UE transmits the SRS; and
performing the second power control for the PUSCH transmission using the second set of parameters and a second TPC command in the second DCI format, in case that the UE transmits data on the PUSCH,
wherein the first set of parameters includes a first path-loss compensation factor for the first power control, and the second set of parameters includes a second path-loss compensation factor for the second power control, and
wherein the first DCI format includes a first cyclic redundancy check (CRC) field scrambled by a TPC-SRS-radio network temporary identifier (RNTI), and the second DCI format includes a second CRC field scrambled by a TPC-PUSCH-RNTI. ]
