1. A device for using null data packets (NDPs), the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
generate a high-efficiency short training field (HE-STF) of an NDP;
generate a symbol for a high-efficiency long training field (HE-LTF) of the NDP;
generate the HE-LTF, wherein the HE-LTF comprises a first zero-power guard interval between the HE-STF of the NDP and the symbol of the HE-LTF;
generate the NDP, the NDP comprising the HE-STF and the HE-LTF, wherein the symbol of the HE-LTF precedes a second zero-power guard interval in the NDP, the second zero-power guard interval preceding a packet extension field in the NDP; and
transmit the NDP to a second device.
