Provided are a method and apparatus for performing beamforming training in a wireless local area network. A responder receives a plurality of beacon frames in a plurality of TX sectors from an initiator during a transmission (TX) beamforming (BF) interval. The responder transmits a first sector sweep feedback for a first array antenna to the initiator during a reception (RX) beamforming (BF) interval. The first sector sweep feedback comprises a first antenna ID indicating a first array antenna and a first TX ID indicating a TX sector selected for the first array antenna from the plurality of TX sectors.

A method for performing a multi-beamforming training and a device using the same are provided. An initiator transmits a first beacon frame for beamforming training on a first channel during a sector sweep and transmits a second beacon frame for beamforming training on a second channel during the sector sweep. The first beacon frame comprises a multi-channel indicator that indicates that beamforming training is performed on the first and second channels.

Proposed is a control field including allocation information regarding a resource unit (RU) in a wireless local area network (WLAN) system supporting a plurality of RUs. A data field may be transmitted in unit of the RU. For a case where two 106-RUs are arranged and a plurality of user stations (STAs) are multiplexed to the respective 106-RUs, a SIG-B field may be used to perform signaling. More specifically, the number of STAs to be multiplexed may be indicated by using first and second identification bits in a user-common field of the SIG-B field.
