Zusammenfassung:	Disclosed are a method and apparatus for retransmission in a sidelink communication. A method of operating a transmission terminal comprises the steps of: transmitting first data to a reception terminal on the basis of a first retransmission scheme; when a preset condition is met, changing a retransmission scheme from the first retransmission scheme to a second retransmission scheme; and transmitting second data to the reception terminal on the basis of the second retransmission scheme. La présente invention concerne un procédé et un appareil de retransmission dans une communication de liaison latérale. Un procédé de fonctionnement d'un terminal d'émission comprend les étapes consistant à : transmettre des premières données à un terminal de réception sur la base d'un premier schéma de retransmission ; lorsqu'une condition prédéfinie est satisfaite, changer le schéma de retransmission, du premier schéma de retransmission à un second schéma de retransmission ; et la transmission de secondes données au terminal de réception sur la base du second schéma de retransmission. 사이드링크 통신에서 재전송을 위한 방법 및 장치가 개시된다. 송신 단말의 동작 방법은, 제1 재전송 방식에 기초하여 제1 데이터를 수신 단말에 전송하는 단계, 미리 설정된 조건이 만족하는 경우, 재전송 방식을 상기 제1 재전송 방식에서 제2 재전송 방식으로 전환하는 단계, 및 상기 제2 재전송 방식에 기초하여 제2 데이터를 상기 수신 단말에 전송하는 단계를 포함한다.
