Abstract

Embodiments of the present disclosure include an apparatus of a user equipment. The apparatus may include at least one processor, and memory storing instructions that, when executed by the at least one processor cause the apparatus to perform operations. In certain aspects, the apparatus may receive one or more code block groups from a base station. In certain other aspects, the apparatus may perform a hybrid automatic repeat request -acknowledgement codebook selection process to determine a smaller HARQ-ACK codebook by calculating a first codebook size associated with the one or more CBGs, calculating a second codebook size associated with the one or more CBGs, and determining whether the first HARQ-ACK codebook or the second HARQ-ACK codebook is a smaller HARQ-ACK codebook by comparing the first codebook size and the second codebook size. In certain other aspects, the apparatus may transmit the smaller HARQ-ACK codebook to the base station.
