Variable uplink grant configurations for high power class devices

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

• transmitting, to a network entity, an advertisement message indicating an uplink transmission duty cycle associated with a first power class mode of the UE, the first power class mode of the UE corresponding to a higher transmission power level than a second power class mode of the UE;
• receiving, from the network entity, a plurality of uplink grants associated with a time interval, a quantity of transmission resources scheduled by the plurality of uplink grants during the time interval exceeding the uplink transmission duty cycle associated with the first power class mode;
• transmitting, using the first power class mode on a first transmission chain of the UE, a first subset of uplink messages associated with a first subset of the plurality of uplink grants to satisfy the uplink transmission duty cycle for the first transmission chain during the time interval;
• and
• transmitting, using the first power class mode on a second transmission chain of the UE, a second subset of the uplink messages associated with a second subset of the plurality of uplink grants to satisfy the uplink transmission duty cycle for the second transmission chain during the time interval.

An apparatus for wireless communications at a user equipment (UE), comprising:

• memory;
• a transceiver;
• and
• at least one processor of the UE, the at least one processor coupled with the memory and the transceiver and configured to:
• transmit, to a network entity via the transceiver, an advertisement message indicating an uplink transmission duty cycle associated with a first power class mode of the UE, the first power class mode of the UE corresponding to a higher transmission power level than a second power class mode of the UE;
• receive, from the network entity via the transceiver, a plurality of uplink grants associated with a time interval, a quantity of transmission resources scheduled by the plurality of uplink grants during the time interval exceeding the uplink transmission duty cycle associated with the first power class mode;
• and
• transmit, via the transceiver and using the first power class mode, a first subset of uplink messages associated with a first subset of the plurality of uplink grants to satisfy the uplink transmission duty cycle for the time interval based at least in part on dropping transmission of a second subset of uplink messages associated with a second subset of the plurality of uplink grants.
