Abstract:
A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. The WDEV receives a null data packet (NDP) announcement frame that specifies a sub-carrier (SC) or tone grouping factor, a communication channel bandwidth, and other WDEV(s) to respond with beamforming feedback. The WDEV process the NDP announcement frame to determine it is to respond, and if so, then receives a NDP sounding frame that includes long training fields (LTFs) and pilots at predetermined locations and generates beamforming feedback of communication channel estimates at SCs as determined based on a sub-carrier roster look up table (LUT).

Claim (Index 1):
A wireless communication device comprising:\n a communication interface; and processing circuitry that is coupled to the communication interface, wherein at least one of the communication interface or the processing circuitry configured to:\n receive, via a communication channel and from another wireless communication device, a null data packet (NDP) sounding frame that includes a plurality of long training fields (LTFs) and a plurality of pilots at predetermined locations; \n identify a set of feedback sub-carrier locations based on a sub-carrier or tone grouping factor and a communication channel bandwidth of a plurality of communication channel bandwidths specified within a NDP announcement frame that is received before the NDP sounding frame; \n process the NDP sounding frame to generate beamforming feedback by estimating the communication channel for each sub-carrier location within the set of feedback sub-carrier locations; and \n transmit, via the communication channel, a beamforming feedback frame to the another wireless communication device that includes estimates of the communication channel for each sub-carrier location within the set of feedback sub-carrier locations.
