Abstract
A method and apparatus informs nodes included in a wireless local area network (LAN) of how to avoid access collision in a wireless LAN. A wireless LAN access point or an independent basic service set (IBSS) control station receives a Contention-Free-End (CF-End) frame, compares a basic service set ID (BSSID) of the received CF-End frame of the access point or the IBSS, and rebroadcasts the received CF-End frame if the comparison result indicates that the two BSSIDs coincide with each other. Thus, all stations included in one BSS can receive the same time information for controlling medium access.
