Abstract: A method and a device for a sidelink in a wireless communication system are provided. A transmission terminal supporting a sidelink performs transmission/reception beam pairing by using control information for a sidelink. The transmission terminal and a reception terminal can find an optimum transmission/reception beam pair on the basis of a method of repeatedly transmitting/receiving control information by the sidelink. Therefore, an appropriate transmission/reception beam pair can be found without repeatedly transmitting a synchronization signal. The reception terminal can provide feedback information on the received control information to the transmission terminal. The transmission terminal can determine an optimum transmission/reception beam pair on the basis of the feedback information.

Abstract: A disclosed feature of the present specification is to provide a method for transmitting a hybrid automatic repeat request (HARQ) acknowledgement/negative-acknowledgement (ACK/NACK) signal using a sidelink. The method may comprise the steps of: receiving from a transmission terminal data in a first time section within a sidelink subframe n; and transmitting a HARQ ACK/NACK signal in a second time section within the sidelink subframe n. A gap may exist between the first time section and the second time section in the sidelink subframe n. The gap can be used for switching between reception and transmission.
