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.
