Title: UPLINK (UL) MULTI-USER (MU) FEEDBACK USING HIGH-EFFICIENCY (HE) LONG TRAINING FIELDS IN A WIRELESS LOCAL-AREA NETWORK
Abstract:
Apparatus, computer readable media, and methods for UL MU feedback using HE-LTFs in a wireless local-area network are disclosed. An apparatus of a station comprising memory and processing circuitry couple to the memory is disclosed. The processing circuitry may be configured to: decode a frame comprising one or more resource block identification (RBIDs), wherein each RBID indicates a resource allocation to transmit one bit of information to a access point. Additionally, the processing circuitry may be configured to encode a response to the availability trigger frame in accordance with the resource allocation indicated by the one or more RBIDs, in response to decoding an availability trigger frame from the access point. The processing circuitry may be configured to configure the station to transmit the response to the access point in accordance with orthogonal frequency division multiple access (OFDMA).
