Abstract

See full text

The present application is related to a method and apparatus for HARQ-ACK codebook determination. A method of receiving information according to one embodiment comprises receiving, from a base unit, a first signal for indicating a first parameter which is a quantity of transport blocks (TBs) in a downlink association set and receiving a second signal for indicating a second parameter which is a quantity of hybrid automatic repeat request acknowledgement (HARQ-ACK) bit fields in a HARQ-ACK codebook, determining a size of the HARQ-ACK codebook based on the first signal and the second signal, and transmitting the HARQ-ACK codebook to the base unit, wherein the HARQ-ACK codebook comprises a first part including K1 HARQ-ACK bits and a second part including K2 HARQ-ACK bit fields, wherein each bit in the first part corresponds to one TB in the downlink association set; and each HARQ-ACK bit field in the second part corresponds to one incorrectly decoded TB in the downlink association set. The present application reduces signaling overhead for a HARQ-ACK codebook and avoids misunderstanding between a base unit and a remote unit when determining a HARQ-ACK codebook.
