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;
wherein the scheduling PDCCH or higher layer grant provides:
at least two sounding reference signal (SRS) resources wherein each SRS resource 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 Demodulation Reference Signal (DMRS) ports, and
performing the scheduled PUSCH transmissions, wherein each PUSCH transmission is performed using the SRS ports of one of the indicated SRS resources and the indicated 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.
