摘要： 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.

摘要： Methods and apparatus for contention window size adjustment are described. A method includes: receiving a first group of feedback signals indicating a first state corresponding to data transmitted in a first band used by a carrier, the first group of feedback signals comprising at least one first feedback signal; receiving a second group of feedback signals indicating a second state corresponding to data transmitted in the first band used by the carrier; determining a first scaling factor α for one of the at least one first feedback signal; determining a ratio of the first group of feedback signals to the first group of feedback signals and the second group of feedback signals; and comparing the ratio to a threshold to determine a contention window size (CWS) of the first band, wherein the first scaling factor α substitutes a weight of the one of the at least one first feedback signal in determination of the ratio of the first group of feedback signals to the first group of feedback signals and the second group of feedback signals.
