摘要： 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.
摘要翻译：方法和装置通知包括在无线局域网（LAN）中的节点如何避免无线LAN中的接入冲突。无线LAN接入点或独立基本业务集（IBSS）控制台接收无争用终结（CF-End）帧，比较接入点的接收到的CF-End帧的基本业务集ID（BSSID）或IBSS，并且如果比较结果指示两个BSSID彼此一致，则重新广播所接收的CF-End帧。因此，包括在一个BSS中的所有站可以接收用于控制媒体访问的相同时间信息。
