Multiplexing codebooks generated for transmissions having different service types

A method for wireless communications by a base station, comprising:

• transmitting a first transmission of a first service type and a second transmission of a second service type, the second service type having a lower latency specification and a higher reliability specification than the first service type;
• transmitting control signaling that indicates a first size of a multiplexed feedback codebook and a second size of a second feedback codebook;
• identifying a feedback codebook size for the first service type based at least in part on transmitting the first transmission of the first service type, the first size, and the second size;
• and
• receiving, in a control channel or a shared data channel, the multiplexed feedback codebook generated based at least in part on a first feedback codebook having the feedback codebook size generated for the first transmission being multiplexed with the second feedback codebook generated for the second transmission.

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

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• monitor for a first transmission of a first service type and a second transmission of a second service type, the second service type having a lower latency specification and a higher reliability specification than the first service type;
• receiving control signaling that indicates a first size of a multiplexed feedback codebook and a second size of a second feedback codebook;
• identify a feedback codebook size for the first service type based at least in part on monitoring for the first transmission of the first service type, on the first size, and the second size;
• multiplex, based at least in part on a feedback multiplexing condition being satisfied, a first feedback codebook having the feedback codebook size generated for the first transmission with the second feedback codebook generated for the second transmission to generate the multiplexed feedback codebook;
• and
• transmit the multiplexed feedback codebook in a control channel or a shared data channel.
