Abstract: A method of a first device communicating with at least one second device in a wireless local area network (WLAN) system includes the first device generating a null data packet announcement (NDPA) frame and transmitting the NDPA frame to the at least one second device. The generating of the NDPA frame includes identifying a protocol version of the at least one second device and the NDPA frame includes an NDPA version subfield generated based on the protocol version.

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.

Abstract: A system and a method are disclosed for controlling sounding or beamforming. In some embodiments, the method includes transmitting, by a first station, an instruction to a second station, the second station being a beamforming station, wherein the instruction instructs the second station: to disable or enable beamforming, or to disable or enable sounding.

Abstract: A wireless communication method performed by a first device includes entering a transmission preparation period of a first Request To Send (RTS) frame via a first link; obtaining transmission-related information of a second RTS frame via a second link; determining at least one of a first transmission timing and content of the first RTS frame, based on the transmission-related information of the second RTS frame; generating the first RTS frame based on a result of the determining; and transmitting, to a second device via the first link, the generated first RTS frame.
