Dynamic physical uplink shared channel configuration

A method of wireless communication comprising:

• transmitting, to a user equipment (UE), a first signaling communication that configures a plurality of transmit precoder matrix indicator (TPMI) and sounding reference signal (SRS) resource indicator (SRI) pairs,
• wherein the plurality of TPMI and SRI pairs are to be used to transmit respective physical uplink shared channel (PUSCH) communications;
• transmitting, to the UE, a second signaling communication that indicates an update to a TPMI and SRI pair of the plurality of TPMI and SRI pairs;
• and
• receiving, from the UE, a PUSCH communication, of the respective PUSCH communications, based at least in part on:
• an indication that the UE is to use a particular TPMI and SRI pair, of the plurality of TPMI and SRI pairs, to transmit the PUSCH communication, or
• a cycling order that specifies an order in which the UE is to cycle through the plurality of TPMI and SRI pairs.

A user equipment (UE) for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to cause the UE to:
• receive a first signaling communication that configures a plurality of transmit precoder matrix indicator (TPMI) and sounding reference signal (SRS) resource indicator (SRI) pairs,
• wherein the plurality of TPMI and SRI pairs are to be used to transmit respective physical uplink shared channel (PUSCH) communications;
• receive a second signaling communication that indicates an update to a TPMI and SRI pair of the plurality of TPMI and SRI pairs;
• and
• transmit a PUSCH communication, of the respective PUSCH communications, based at least in part on:
• an indication that the UE is to use a particular TPMI and SRI pair, of the plurality of TPMI and SRI pairs, to transmit the PUSCH communication, or
• a cycling order that specifies an order in which the UE is to cycle through the plurality of TPMI and SRI pairs.

A network entity for wireless communication, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to cause the network entity to:
• transmit, to a user equipment (UE), a first signaling communication that configures a plurality of transmit precoder matrix indicator (TPMI) and sounding reference signal (SRS) resource indicator (SRI) pairs,
• wherein the plurality of TPMI and SRI pairs are to be used to transmit respective physical uplink shared channel (PUSCH) communications;
• transmit, to the UE, a second signaling communication that indicates an update to a TPMI and SRI pair of the plurality of TPMI and SRI pairs;
• and
• receive, from the UE, a PUSCH communication, of the respective PUSCH communications, based at least in part on:
• an indication that the UE is to use a particular TPMI and SRI pair, of the plurality of TPMI and SRI pairs, to transmit the PUSCH communication, or
• a cycling order that specifies an order in which the UE is to cycle through the plurality of TPMI and SRI pairs.
