1. A method of a second device communicating with a first device in a wireless local area network (WLAN) system, the method comprising:
receiving, by the second device, a null data packet announcement (NDPA) frame from the first device, the NDPA frame comprising a medium access control (MAC) header and a frame body;
extracting, by the second device, an NDPA version subfield from the frame body;
identifying, by the second device, a protocol version based on the NDPA version subfield; and
decoding, by the second device, the NDPA frame based on the protocol version,
wherein the MAC header comprises a frame control field.
