1. A method performed in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a station (STA), a Null Data Packet Announcement (NDPA) frame,
wherein the NDPA frame includes a Sounding Dialog Token field related to a sensing measurement exchange,
wherein the NDPA frame includes a STA info field,
wherein the STA info field includes an Association Identifier (AID) field and a one-bit control field which is located in a thirty-second bit of the STA info field,
wherein the one-bit control field is denoted by ‘B31’ in the STA info field,
wherein the NDPA frame includes a plurality of variants including a Sensing NDPA frame and a Ranging NDPA frame,
wherein the plurality of variants are distinguished based on two contiguous bits of the Sounding Dialog Token field, the AID field, and the one-bit control field,
wherein the two contiguous bits of the Sounding Dialog Token field have a same value for the Sensing NDPA frame and the Ranging NDPA frame,
wherein the STA info field further includes a measurement session identifier (ID) of the sensing measurement exchange; and
transmitting, by the STA, the null data packet (NDP) frame based on the NDPA frame.
