Abstract
A method for a first device to communicate with at least one second device in a wireless local area network (WLAN) system includes providing a first trigger frame to at least one second device, the first trigger frame requesting at least one sounding null data packet (NDP), providing a feedback frame to the at least one second device, the feedback frame including feedback information generated based on the at least one sounding NDP, and providing a second trigger frame to the at least one second device, the second trigger frame requesting at least one beamformed physical layer protocol data unit (PPDU), each of the first trigger frame and the feedback frame including a sounding dialog token number field having a sounding sequence number.
