Abstract: A method for allocating a plurality of resource units among a plurality of client stations in a wireless local area network is disclosed herein. An access point (AP) estimates a channel quality indicator for each of the respective channels between the AP and the plurality of client stations, obtains queue information corresponding to each of the plurality of client stations, and computes a utility function for each of the plurality of client stations based on the channel quality indicator and the obtained queue information. The AP then allocates each resource unit to a client station of the plurality of client stations having a highest value output by the respective utility function.

Abstract: A method for rate adaptation in a communication device includes, during a time interval, transmitting over a wireless channel to a peer communication device both (i) communication packets that carry user data, at a communication data rate, and (ii) channel-probing packets for probing channel conditions, at a channel-probing data rate that is derived from the communication data rate. A first statistical performance of the communication packets, and a second statistical performance of the channel-probing packets, are estimated over the time interval. The communication data rate is set for a subsequent time interval based on at least one of the first statistical performance and the second statistical performance.
