Abstract
The present specification discloses a method by which a station transmits/receives a signal in a wireless LAN (WLAN) system, and a device therefor. More particularly, disclosed are: a method for performing beamforming training for a plurality of channels and transmitting/receiving a signal on the basis of the beamforming training, when the station transmits/receives the signal through the plurality of channels; and a device therefor.
Claims14
A method for transmitting a signal by a first station (STA) to a second station (STA) through multiple channels in a wireless LAN (WLAN) system, comprising:
- performing beamforming training procedure on the multiple channels for the second STA by transmitting a Physical Protocol Data Unit (PPDU) through the multiple channels to the second STA, wherein the PPDU is differently configured based on whether the PPDU is transmitted based on a channel bonding or a channel aggregation;
- and
- transmitting the signal through the multiple channels to the second STA based on the beamforming training procedure,
- wherein in case the PPDU is transmitted based on the channel aggregation, the PPDU includes a Legacy Shot Training Field (L-STF) field, a Legacy Channel Estimation (L-CE) field, a Legacy Header (L-Header) field, an Enhanced Directional Multi Gigabit Header A (EDMG Header A) field, and a Beam Refinement Protocol (BRP) field, which are duplicated for aggregated channels included in the multiple channels, and the PPDU further includes a Training (TRN) field having a gap configured between the aggregated channels, and
- wherein in case the PPDU is transmitted based on the channel bonding, the PPDU includes a L-STF field, a L-CE field, a L-Header field, an EDMG Header A field, and a BRP field, which are duplicated for bonded channels included in the multiple channels, and the PPDU further includes a TRN field being transmitted through an entire bandwidth of the bonded channels.

A station device for transmitting a signal through multiple channels in a wireless LAN (WLAN) system, comprising:
- a transmitting/receiving unit having one or more radio frequency (RF) chains and being configured to transmit/receive a signal to/from another station device;
- and
- a processor being operatively connected to the transmitting/receiving unit and performing signal processing of the signal transmitted/received to/from the other station device,
- wherein the processor is configured:
- to perform beamforming training on the multiple channels for the other station device by transmitting a Physical Protocol Data Unit (PPDU) through the multiple channels to the other STA, wherein the PPDU is differently configured based on whether the PPDU is transmitted based on a channel bonding or a channel aggregation, and
- to transmit the signal through the multiple channels to the other station device based on the beamforming training procedure,
- wherein in case the PPDU is transmitted based on the channel aggregation, the PPDU includes a Legacy Shot Training Field (L-STF) field, a Legacy Channel Estimation (L-CE) field, a Legacy Header (L-Header) field, an Enhanced Directional Multi Gigabit Header A (EDMG Header A) field, and a Beam Refinement Protocol (BRP) field, which are duplicated for aggregated channels included in the multiple channels, and the PPDU further includes a Training (TRN) field having a gap configured between the aggregated channels, and
- wherein in case the PPDU is transmitted based on the channel bonding, the PPDU includes a L-STF field, a L-CE field, a L-Header field, an EDMG Header A field, and a BRP field, which are duplicated for bonded channels included in the multiple channels, and the PPDU further includes a TRN field being transmitted through an entire bandwidth of the bonded channels.
