Abstract (en)
[origin: WO2022216757A1] Aspects relate to wireless communication having sounding reference signal (SRS) power control using non-scheduling downlink control information (DCI) that is configured to trigger aperiodic SRS without scheduling data and without a channel state information (CSI) request. The non-scheduling is configured to include at least two transmit power control (TPC) commands. A first TPC command is configured for power control of a physical uplink shared channel (PUSCH) transmitted by a UE to a base station. A second TPC command is configured for power control of one or more sounding reference signal (SRS) resource sets. Additionally, the first TPC command may be independent from the second TPC command where different power control is implemented for the PUSCH and the SRS transmissions. Additionally, the non-scheduling DCI may be formatted according to a DCI format 0_1 or a DCI format 0_2.
