CONTENTION ACCESS METHOD, CONTENTION ACCESS DEVICE, BASE STATION AND CONTENTION ACCESS SYSTEM

摘要

The present invention provides a communications method applied to a WLAN, comprising: a station receiving a trigger frame sent by an access point, the trigger frame indicating that a part of sub-channels is allocated to a scheduled station, and another part of the sub-channels is for random access; if the station is a scheduled station, monitoring whether or not the sub-channel allocated to the station is busy; if so, then randomly selecting an idle random access sub-channel and sending data, or first performing a backoff, and after the backoff is complete, again randomly selecting an idle random access sub-channel and sending data. The present invention provides a WLAN communications method and related apparatus, capable of effectively improving station uplink access efficiency and network functions.
