UNIFIED FEEDBACK FOR OFDMA WLAN

摘要

A method of resource feedback with an access point in a wireless local area network (WLAN) may include sending communications in the WLAN from the access point to a plurality of stations using one of orthogonal frequency-division multiple access (OFDMA) or multiple-input, multiple-output (MIMO) signaling. The method may include sending, in a null data packet announcement (NDPA) frame, from the access point, to each of the plurality of stations, a resource unit channel quality feedback request for at least one resource unit within a first bandwidth; sending, a null data packet (NDP), from the access point to each of the plurality of stations to measure and provide a channel quality for the at least one resource unit within the first bandwidth sent to each of the plurality of stations; receiving, at the access point from at least one of the plurality of stations, a resource unit channel quality feedback response comprising an indication of the channel quality for the resource unit within the first bandwidth for the at least one of the plurality of stations; and/or either scheduling at the access point at least one allocated resource unit for the at least one of the plurality of stations to send a data transmission to the access point based on the feedback response or sending a request to the at least one of the plurality of stations to send channel information based on the feedback response.
