METHODS AND MECHANISM FOR CHANNEL ACCESS

Abstract

The invention relates to a method and apparatus for accessing channels, chips, computer-readable storage media, and communication systems. The method includes: A first device that identifies the first frame, in which the first frame includes the first indicator information, the first indicator information indicating the first access point (AP) in at least one AP to perform contention access for the first traffic in the first slot, and the first traffic includes traffic for which channel access is performed using priority interframe space (PIFS); and a first device that sends the first frame to the first AP. According to the invention's scheme, contention and conflict with other APs during channel access are avoided, thereby improving the quality of service for the traffic.
