Abstract
The present specification relates to a method for transmitting or receiving data by a station in a wireless LAN (WLAN) system and, more particularly, presents a method and device for transmitting or receiving data on the basis of a beamforming training method for a plurality of channels, when a station transmits the data by using the plurality of channels.
Claims13
A method for transmitting data by a first station (STA) to a second STA through at least one channel in a wireless LAN (WLAN) system, the method comprising:
- performing first beamforming training on the at least one channel for the second STA, wherein the first STA transmits a first Beam Refinement Protocol (BRP) frame to the second STA and receives a second BRP frame from the second STA through the at least one channel while performing the first beamforming training;
- and
- transmitting the data to the second STA through the at least one channel based on the first beamforming training,
- wherein a training (TRN) field is appended to an end of the first BRP frame and an end of the second BRP frame.
A method for receiving data by a first station (STA) from a second STA through at least one channel in a wireless LAN (WLAN) system, the method comprising:
- performing first beamforming training on the at least one channel for the second STA, wherein the first STA transmits a first Beam Refinement Protocol (BRP) frame to the second STA and receives a second BRP frame from the second STA through the at least one channel while performing the first beamforming training;
- and
- receiving the data from the second STA through the at least one channel based on the first beamforming training, wherein a training (TRN) field is appended to an end of the first BRP frame and an end of the second BRP frame.
A station (STA) for transmitting data through at least one channel in a wireless LAN (WLAN) system, the station comprising:
- a transceiver having one or more Radio Frequency (RF) chains and configured to transmit and receive signals to and from another station;
- and
- a processor connected to the transceiver and configured to process the signals transmitted or received with the another station,
- wherein the processor is further configured to:
- perform first beamforming training on the at least one channel for the another STA, wherein the first STA transmits a first Beam Refinement Protocol (BRP) frame to the second STA and receives a second BRP frame from the second STA through the at least one channel while performing the first beamforming training;
- and
- transmit the data to the another STA through the at least one channel based on the first beamforming training,
- wherein a training (TRN) field is appended to an end of the first BRP frame and an end of the second BRP frame.
