MANAGEMENT OF SINGLE-SHOT HARQ-ACK CODEBOOKS ALONG WITH HARQ-ACK CODEBOOKS WITH SET PRIORITY LEVELS

Abstract:

Aspects relate to configuring and managing hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback codebooks for use in wireless communication systems. The HARQ-ACK codebooks include priority-based HARQ-ACK codebooks of differing priorities, such as Type 1 and Type 2 codebooks, and one-shot (Type 3) HARQ-ACK codebooks. In one example, a wireless communication device may be configured to obtain a set of HARQ-ACK codebooks that include priority-based HARQ-ACK codebooks of differing priorities and a separate one-shot HARQ-ACK codebook. The wireless communication device may further be configured to process first and second physical uplink channels based on the priority of the first physical uplink channel and the priority of the second physical uplink channel, where one of the two physical uplink channels includes the one-shot HARQ-ACK codebook, and with the processing performed in combination with the use of the priority-based HARQ-ACK codebooks.
