1. A method of transmitting a frame by a first device in a wireless local area network, the method comprising:
- receiving a second frame including bandwidth information of a second channel from a second device before transmitting a first frame, the second channel being selected from among a plurality of channels into which an entire channel width is divided;
transmitting the first frame including bandwidth information of a first channel directly to the second device, the first channel being selected from among the plurality of channels into which the entire channel width is divided and discontinuous channels capable of being selected as the first channel from among the plurality of channels; and
performing a direct communication with the second device through the first channel,wherein a direct transmission is performed through a third channel between a third device and a fourth device when the direct communication with the second device through the first channel is performed, the third channel is determined by the third device using the bandwidth information included in the second frame and the bandwidth information included in the first frame, and the third channel is a part of the plurality of channels and the first and third channels have disjoint bandwidths, andwherein each channel of the plurality of channels is a wireless channel, andwherein the second channel has a bandwidth that includes the first channel and the third channel.

Abstract
A method of transmitting a frame is provided by a first device in a WLAN. The first device transmits a first frame including bandwidth information of a first channel to a second device and performs a communication with the second device through the first channel. The first channel is selected from among a plurality of channels into which an entire channel width is divided. Discontinuous channels are capable of being selected as the first channel from among the plurality of channels.

15. A method of receiving a frame by a first device in a wireless local area network, the method comprising:
-
transmitting a second frame including bandwidth information of a second channel to a second device before receiving a first frame; receiving the first frame including bandwidth information of a first channel directly from the second device, the first channel being selected from among a plurality of channels into which an entire channel width is divided and discontinuous channels capable of being selected as the first channel from among the plurality of channels; and performing a direct communication with the second device through the first channel, wherein a direct transmission is performed through a third channel between a third device and a fourth device when the direct communication with the second device through the first channel is performed, the third channel is a part of the plurality of channels and does not include the first channel, the third channel is determined by the third device using the bandwidth information included in the second frame and the bandwidth information included in the first frame, and the first and third channels have disjoint bandwidths, and wherein each channel of the plurality of channels is a wireless channel, and wherein the second channel has a bandwidth that includes the first channel and the third channel. - View Dependent Claims (16, 17, 18, 19, 20)
