US 10,952,086 B2 · Fast rate adaptation for WLAN devices

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.
