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.
