Abstract: A method for transmitting data in a wireless LAN may comprise the steps of: receiving a non-target clear to send (CTS) frame from a second station (STA) by a first STA; transmitting a request to send (RTS) frame to a first access point (AP) coupled with the first STA within a network allocation vector (NAV) interval configured on the basis of the non-target CTS frame by the first STA; receiving a CTS frame in response to the RTS frame from the first AP by the first STA; and transmitting a first data frame to the first AP by the first STA.

Abstract: The present invention relates to a Method for a device-to-device (D2D) communication in a wireless communication system. Specifically, when a terminal, which is performing a device-to-device communication while performing channel hopping, additionally performs the device-to-device communication with a new terminal, a channel hopping period of the existing device to device communication is configured by same time intervals for channels and one time interval among the same time intervals is configured to be identical to a channel hopping period for discovering a new terminal.
