Abstract
The present specification proposes a method for a station to transmit and receive a signal in a wireless LAN (WLAN) system and an apparatus therefor. More specifically, when the station transmits and receives a signal via a plurality of channels, the present invention proposes a method of performing beamforming training on the plurality of channels, a method of transmitting and receiving a signal based on the beamforming training and an apparatus therefor.
Claims16
A method performed by a first station (STA) in a wireless LAN (WLAN) system, the method comprising:
- transmitting a beam refinement protocol (BRP) packet to a second STA through a plurality of channels, wherein the BRP packet is generated based on a lowest modulation and coding scheme (MCS), and wherein the plurality of channels is generated based on a channel bonding scheme or a channel aggregation scheme;
- and
- performing a beamforming training procedure on the plurality of channels for the second STA based on the BRP packet,
- wherein the BRP packet includes an Enhanced Directional Multi Gigabit Header A (EDMG Header A) field, a Beam Refinement Protocol (BRP) data frame, and a Training (TRN) field,
- wherein the BRP data frame is duplicated for the plurality of channels, and
- wherein the TRN field is transmitted through bonded channels generated based on the channel bonding scheme according to information in the EDMG Header A field.
