In one example, the circuitry is configured to generate a null data packet (NDP), transmit at least a portion of the NDP to another wireless communication device via fewer than all of a plurality of sub-channels of a communication channel, and receive feedback from the another wireless communication device that is based on the another wireless communication device processing the at least the portion of the NDP that is received via the fewer than all of the plurality of sub-channels of the communication channel. In one example, the generated NDP includes at least one signal field (SIG) therein that includes information to specify a preamble puncturing option or the information is transmitted in a previous packet.
