Abstract

A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured transmit, to a set of stations, a trigger frame that indicates a set of RUs for uplink and/or downlink transmission available to each station of the set of stations. The trigger frame may be a request for feedback on the set of RUs from each station. The apparatus may be configured to receive from each station a response frame over an uplink resource based on the transmitted trigger frame. The response frame may include the feedback on the set of RUs and may be received independent of a channel condition associated with the uplink resource. The feedback may be an ordered list of RUs based on the set of RUs.

Claims17

Dependent claims

A method of wireless communication by an apparatus, comprising:

generating, for transmission to a set of stations, a first frame that indicates a set of resource units (RUs) available for transmission to each station of the set of stations, wherein the first frame comprises a request for feedback on the set of RUs from each station;
outputting, for transmission to the set of stations, the first frame;
and
obtaining, from each station, a response frame based on the first frame, wherein the response frame includes a bitmap indicating the feedback on the set of RUs.

An apparatus for wireless communication comprising:

a processing system configured to:
generate a first frame to be transmitted to a set of stations, wherein the first frame indicates a set of resource units (RUs) available for transmission to each station of the set of stations, and wherein the first frame comprises a request for feedback on the set of RUs from each station, and
obtain, from each station, a response frame based on the first frame, wherein the response frame includes a bitmap indicating the feedback on the set of RUs;
and
a bus system configured to provide the first frame for transmission and obtain the response frame.
