Title: METHOD, ACCESS POINT, AND SYSTEM FOR TRANSMITTING MULTI-STATION CONTROL FRAME
Abstract:
Disclosed are a method, access point, and system for transmitting a multi-station control frame. The method comprises: transmitting a multi-station control frame to multiple stations, where, insofar as the multi-station control frame is a request frame, the request frame is used for requesting each station of the multiple stations to respectively transmit a first response frame corresponding to the multi-station control frame; receiving the first response frames transmitted respectively by each station of the multiple stations and corresponding to the multi-station control frame; or, insofar as the multi-station control frame is a second response frame, the second response frame is used for responding to data frames or management frames or control frames transmitted by the multiple stations, where the multi-station control frame comprises: a conventional preamble field and a novel preamble field. The novel preamble field comprises: a first signaling field and a second signaling field. Compared with an 802.11ax multi-station control frame, the number of bytes occupied by the multi-station control frame is greatly reduced. As such, the time during which a channel is occupied in the process of transmitting the multi-station control frame can be reduced.
