Abstract

See full text

Optimal determination of a Wireless Local Area Network (WLAN) sounding method and system may be provided. An Access Point (AP) selects a subchannel for the partial sounding. The AP then sounds the selected subchannel. A client station responds with Channel State Information (CSI). The AP can receive the CSI, from the client station, in response to the sounding. Based on the CSI from the selected subchannel, the AP extrapolates the CSI to determine predicted CSI for a wider bandwidth channel.
