1. A method performed in a wireless local area network (WLAN) system, the method comprising:
transmitting 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 further includes a station (STA) info field,
wherein the STA info field includes an Association Identifier (AID) field and one-bit information which is denoted by ‘B31’ in the STA info field,
wherein the NDPA frame includes a plurality of variants including a Very High Throughput (VHT) NDPA frame, a High-Efficiency (HE) NDPA frame, a Ranging NDPA frame, a Sensing NDPA frame, and an Extremely High Throughput (EHT) NDPA frame,
wherein the plurality of variants are distinguished based on two-bit information of the Sounding Dialog Token field, the AID field, and the one-bit information,
wherein the two-bit information has a first value for the VHT NDPA frame, the two-bit information has a second value for the Sensing NDPA frame and the Ranging NDPA frame, the two-bit information has a third value for the HE NDPA frame, and the two-bit information has a fourth value for the EHT NDPA frame,
wherein the STA info field further includes a measurement session identifier (ID) of the sensing measurement exchange; and
transmitting the null data packet (NDP) frame, wherein the NDP frame is preceded by the NDPA frame.
