Patent ID: 11943646
Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 5:
6. A station (STA) in a wireless local area network (WLAN) system, comprising:
a transceiver adapted to transmit and/or receive a wireless signal; and
a processor adapted to control the transceiver,
wherein the processor is further adapted to:
transmit 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
transmit the null data packet (NDP) frame based on the NDPA frame.
