1. A method of operating a wireless device comprising:
transmitting a physical layer protocol data unit on one or more channels, wherein the physical layer protocol data unit comprises:
a first portion comprising a signal length field indicating a duration of a transmission of the physical layer protocol data unit; and
a second portion comprising a plurality of Wi-Fi sensing fields,
wherein the second portion of the physical layer protocol data unit further comprises:
a sequence type field to indicate that individual Wi-Fi Sensing fields of the plurality of Wi-Fi Sensing fields comprise either time domain sequences or frequency domain sequences;
a number of transmit antennas used to transmit the physical layer protocol data unit; and
a stream type field to indicate that the plurality of Wi-Fi Sensing fields comprise either a single stream or multiple-input multiple-output (MIMO) streams.
