Methods of dispute over channels, communication equipment, wireless communication systems, and computer-readable storage media

Abstract

The invention relates to a method for channel contention, a communication device, a wireless communication system, and a storage medium readable by a computer. This method comprises the following steps: After data transmission on the first link is completed or a block of data corresponding to data received on the first link is acknowledged, the station other than the first access point of the first link device performs clear channel assessment. CCA) on the second link during the first time interval, where the start time corresponding to the first time interval is the same as the time at which data transmission on the first link is completed; and when CCA detection on the second link fails, the station that is not the first access point conducts channel contention on the second link based on the second time interval. By implementing the solutions of this invention, conflicts and inter-frame interference during channel contention are avoided.
