Method and apparatus for receiving sensing results in a wireless LAN system
Abstract:
Provided are a method and apparatus for receiving sensing results in a wireless local area network (LAN). The method, with the first station serving as an unlicensed device, allowed to operate in an available channel not being used by a licensed device at a TV white space band, includes: transmitting a frame including a first element having information on a point when sensing is performed and a second element having a reporting sequence bitmap representing stations selected from a plurality of second stations to perform sensing and the sensing result report order of the selected stations to the second stations, receiving a measurement report frame, including a sensing result at the point when the sensing is performed, from each of the selected stations based on the sensing result report order, and determining, using the measurement report frame, whether the licensed device is using a channel used by the first station.
