Title: DATA TRANSMISSION CONTROL METHOD, ACCESS POINT AND STATION
Abstract:
Disclosed is a data transmission control method. The method comprises: after confirming that a channel is idle, an access point sending a first control frame, wherein the first control frame comprises a first Duration field and carries an identification of a basic service set; after a station receives the first control frame, if the station is included in the basic service set, the station replying to the access point with a second control frame, wherein the second control frame carries the identification of the basic service set; and after receiving the second control frame, the access point performing data transmission with the station. If the station is not included in the basic service set and causes interference for data transmission in the basic service set, the station updates an NAV according to the value of the first Duration field. Hence, interference can be avoided; because the access point permits stations in the basic service set to participate in communication and there are usually a plurality of stations in one basis service set, during a period of time, more than one station can perform data transmission, thereby improving the bandwidth utilization rate.
