1. A method performed by a user equipment (UE), the method comprising:
receiving from a network node, a single physical downlink control channel (PDCCH) or a higher layer grant that schedules at least two physical uplink shared channel (PUSCH) transmission occasions for the UE,
wherein all the scheduled PUSCH transmission occasions are associated with the same PUSCH transport block, and
wherein the scheduling PDCCH or higher layer grant provides:
at least two groups of sounding reference signal (SRS) resources wherein each group comprises at least one SRS resource and each group of SRS resources is associated with a different SRS resource set, and wherein an SRS resource set is a higher layer configuration that comprises one or more SRS resources;
at least two transmit power control (TPC) commands; and
one or more DMRS ports; and
performing the scheduled PUSCH transmissions, wherein each PUSCH transmission is performed using the SRS ports of one of the indicated groups of SRS resources and the indicated demodulation reference signal (DMRS) ports, on a set of symbols that is distinct from any other PUSCH transmission scheduled by the PDCCH or higher layer grant, and is associated with one of the indicated TPC commands.
