본 개시는 보다 높은 데이터 전송률을 지원하기 위한 5G 또는 6G 통신 시스템에 관련된 것이다. 본 개시는 단말 간 직접 통신을 위한 초기 빔 설정 방법 및 장치에 관한 것으로, 보다 구체적으로는 beam forming을 활용하여 단말 간 직접 통신을 수행하는 기법, 예를 들어 sidelink에서 초기 빔 설정 및 단말 탐지를 수행하는 방법 및 장치에 대한 것이다. The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a first terminal in a communication system, according to an embodiment of the present disclosure, comprises the steps of: identifying a sidelink resource; transmitting a beam acquisition request on the sidelink resource; receiving, from a second terminal, a response to the beam acquisition request; and transmitting ID information of the first terminal to the second terminal, wherein the beam acquisition request may be transmitted on the basis of a reference signal without the ID information of the first terminal, and the beam acquisition request may be transmitted on the basis of a portion of one slot.
