Abstract

An operating method of a first device communicating with a second device in a wireless local area network (WLAN), includes: receiving, from the second device, a physical layer protocol data unit (PPDU) including a payload that includes a trigger frame; preparing an uplink beamforming matrix based on a value of an uplink beamforming-related first sub-field included in a preamble of the PPDU; beamforming, according to the uplink beamforming matrix, the PPDU; and transmitting the beamformed PPDU to the second device based on a value of an uplink beamforming-related second sub-field included in the trigger frame.
