Patent attributes
An example communications device includes communications circuitry and control circuitry. The communications circuitry may wirelessly communicate with multiple receiver antennas concurrently via multiple transmit antennas. The control circuitry may execute an adaptive sounding process that may include, for each client connected to the communications device, performing a follow-up sounding for the client in response to determining that all of the following conditions are jointly satisfied: (a) a wireless channel of the client has significantly changed, as determined based on a channel correlation metric; (b) a wireless throughput has significantly decreased, as determined based on a throughput gradient metric; and (c) the client had a significant amount of recent traffic, as determined based on a traffic metric.
