Methods and apparatuses for physical uplink shared channel for multi transmit-receive-point communications in a wireless communications network

A user equipment (UE) comprising a processor and a memory containing instructions executable by the processor, whereby said UE is configured to:

• receive 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 demodulation reference signal (DMRS) ports;
• and
• perform 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 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.

A method performed by a network node, the method comprising:

• configuring a user equipment (UE) to receive 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 demodulation reference signal (DMRS) ports,
• for enabling the UE to perform the scheduled PUSCH transmissions, wherein each PUSCH transmission is performed using the SRS port of one of the indicated groups of 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.
