Claim 0:
1. A method for wireless communication at a station (STA), comprising:
receiving, from an access point (AP), a sounding signal comprising one or more spatial streams transmitted over an operating bandwidth;
determining a first set of channel characteristics of the operating bandwidth for an average channel of the operating bandwidth based at least in part on receiving the sounding signal, the first set of channel characteristics comprising a first dimensionality and a second dimensionality to;
reducing a value of the first dimensionality of the first set of channel characteristics for the average channel of the operating bandwidth based at least in part on a feedback reduction parameter corresponding 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;
determining a second set of channel characteristics for the averaging bandwidth based at least in part on reducing the first set of channel characteristics; and
transmitting, to the AP, the second set of channel characteristics,
wherein:
determining the first set of channel characteristics comprises:
determining the average channel of the operating bandwidth based at least in part on the averaging bandwidth; and
determining the second set of channel characteristics comprises:
determining a set of differential characteristics between the reduced first set of channel characteristics corresponding to the averaging bandwidth for calculating the average channel and characteristics of a second channel of the operating bandwidth.
