    Abstract: A method for beamforming training and a device using the same are provided. A station (STA) receives a beacon frame from an access point (AP) during a beacon transmission interval (BTI). The beacon frame includes information on a sector sweep (SSW) frame type used in at least one of a plurality of SSW slots. During association beamforming training (A-BFT), the STA transmits the SSW frame according to the SSW frame type from an SSW slot, among a plurality of SSW slots, having succeeded in a random backoff.

    Abstract: Proposed are a method and apparatus for transmitting a feedback frame in a wireless local area network (WLAN) system. Specifically, a first STA generates the feedback frame based on multi user (MU)-multi input multi output (MIMO) beamforming. The first STA transmits the feedback frame to a second STA. The feedback frame includes information related to a feedback subcarrier for a predetermined frequency band and a beamforming report field for the MU-MIMO beamforming. The feedback subcarrier includes a first subcarrier transmitted first in the feedback subcarrier and a second subcarrier of which a subcarrier index is determined based on a grouping value related to a subcarrier spacing. The beamforming report field includes a first signal to noise ratio (SNR) for the first subcarrier and a first differential SNR for the second subcarrier. The first differential SNR is an SNR difference between adjacent subcarriers included in the feedback subcarrier.

    Abstract: Disclosed are a mobile terminal capable of starting data sharing through an infrared signal and a control method therefor. To this end, the mobile terminal may comprise: a wireless communication unit for performing wireless communications; and infrared transceiver for transmitting and receiving an infrared signal; a user input unit for receiving a user input; and a control unit for controlling a first infrared signal to be output through the infrared transceiver when a first user input is received through the user input unit, and controlling shared data to be transmitted to an external terminal through the wireless communication unit when a second infrared signal is received from the external terminal which has received the first infrared signal.
