Multiplexing codebooks generated for transmissions having different service types

Abstract:

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for a first transmission of a first service type (e.g., enhanced mobile broadband (eMBB)) and a second transmission of a second service type (e.g., ultra-reliable low-latency communication (URLLC)). The UE may identify a feedback codebook size for the first service type. The UE may multiplex a first feedback codebook having the identified feedback codebook size and generated for the first transmission with a second feedback codebook generated for the second transmission. Multiplexing the first and second feedback codebooks may produce a multiplexed feedback codebook. In some cases, the UE may perform the multiplexing based on a feedback multiplexing condition being satisfied. The UE may transmit the multiplexed feedback codebook in a control channel (e.g., a physical uplink control channel (PUCCH)) or a shared data channel (e.g., a physical uplink shared channel (PUSCH)).
