Claim 15:
16. A method for wireless communication at an access point (AP), comprising:
determining a feedback reduction parameter for a channel sounding procedure, wherein the feedback reduction parameter is for reducing a value of a first dimensionality of a set of channel characteristics for an average channel;
transmitting, to a station (STA), a sounding signal comprising one or more spatial streams transmitted over an operating bandwidth, wherein the feedback reduction parameter corresponds to an averaging bandwidth for calculating the average channel, the averaging bandwidth being based at least in part on a signal strength threshold corresponding to a localized average channel of the average channel calculated for a sub-bandwidth of the operating bandwidth, wherein the sounding signal comprises the feedback reduction parameter, the feedback reduction parameter being determined in a bi-directional joint procedure between the STA and the AP; and
receiving the set of channel characteristics and the feedback reduction parameter from the STA based at least in part on transmitting the sounding signal, the set of channel characteristics having a reduced first dimensionality or a reduced second dimensionality, or both according to the feedback reduction parameter,
wherein the feedback reduction parameter is based at least in part on the averaging bandwidth for calculating the average channel.
