1. A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
generate a high efficiency (HE) long training field (HE-LTF) sequence comprising subcarriers phase-shifted by an integer multiple of π/4;
generate a secure null data packet (NDP) comprising the HE-LTF sequence; and
transmit the secure NDP using a first spatial stream.
