1. A communications circuit, comprising one or more communications processors configured to:
generate a null data packet (NDP) comprising an identification of a preamble puncturing option;
transmit, via a communications interface, at least a portion of the NDP to a device via a first subset of a plurality of sub-channels of a communication channel, wherein a second subset of the plurality of the sub-channels is unused by the transmission;
receive, via the communications interface, feedback from the device that is based on the device processing the at least the portion of the NDP that is received via the first subset of the plurality of sub-channels of the communication channel; and
process a portion of the feedback from the device while ignoring another portion of the feedback from the device that corresponds to at least one of the second subset of the plurality of sub-channels of the communication channel.
