Abstract: A first communication device transmits a null data packet (NDP) to multiple second communication devices. The NDP spans a channel frequency bandwidth. The first communication device receives a plurality of sounding feedback packets from the second communication devices. Each sounding feedback packet includes one or more signal-to-noise ratio (SNR) indicators corresponding to one or more respective groups of orthogonal frequency division multiplexing (OFDM) subcarriers, and the SNR indicators correspond to reception of the NDP at the plurality of second communication devices. Each sounding feedback packet in the plurality of sounding feedback packets includes a respective indication of OFDM subcarriers for which the sounding feedback packet includes SNR information, and at least one sounding feedback packet from among the plurality of sounding feedback packets does not include SNR information for all OFDM subcarriers via which the NDP was transmitted.
