Abstract
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for channel coding techniques based on unequal error protection for multiplexed LP UCI and HP UCI. In aspects, a UE may multiplex a set of LP UCI bits with a set of HP UCI bits. The set of HP UCI bits may be encoded through both a first encoder and a second encoder, and the set of LP UCI bits may be encoded through the second encoder to generate a set of coded UCI bits. The UE may transmit, to a base station, the set of coded UCI bits through one of a PUCCH or a PUSCH.

An apparatus for wireless communication at a user equipment (UE), comprising:
- memory;
- and
- at least one processor coupled to the memory, wherein the at least one processor is configured to:
- multiplex a set of low priority (LP) uplink control information (UCI) bits with a set of high priority (HP) UCI bits;
- encode the set of LP UCI bits once through a second encoder and the set of HP UCI bits twice, initially through a first encoder and subsequently as coded bits through the second encoder, to generate a set of coded UCI bits;
- and
- transmit, to a base station, the set of coded UCI bits through one of a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).
An apparatus for wireless communication at a base station, comprising:
- memory;
- and
- at least one processor coupled to the memory, wherein the at least one processor is configured to:
- transmit, to a user equipment (UE), coding rate information for a first encoder of a set of high priority (HP) uplink control information (UCI) bits and a second encoder of a set of low priority (LP) UCI bits and the set of HP UCI bits subsequent to a coding by the first encoder, a first encoding of the set of HP UCI bits and a second encoding of the set of LP UCI bits and the set of HP UCI bits corresponding to a multiplexed set of coded UCI bits;
- and
- receive, from the UE, the multiplexed set of coded UCI bits through one of a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).
