Abstract Disclosed are a method and a device for retransmission in sidelink communication. An operation method of a transmission terminal comprises the steps of: transmitting first data to a reception terminal on the basis of a first retransmission scheme; transmitting, to the reception terminal, SCI including a first indicator indicating switching of a retransmission scheme and a second indicator indicating whether to reuse a resource reserved for the first retransmission scheme; and transmitting second data to the reception terminal on the basis of a second retransmission scheme started by the SCI. L'invention concerne un procédé et un dispositif de retransmission dans une communication de liaison latérale. Un procédé de fonctionnement d'un terminal de transmission comprend les étapes consistant à : transmettre des premières données à un terminal de réception d'après un premier schéma de retransmission ; transmettre, au terminal de réception, des SCI comprenant un premier indicateur indiquant la commutation d'un schéma de retransmission, ainsi qu'un second indicateur indiquant s'il faut réutiliser une ressource réservée pour le premier schéma de retransmission ; et transmettre des secondes données au terminal de réception d'après un second schéma de retransmission lancé par les SCI. 사이드링크 통신에서 재전송을 위한 방법 및 장치가 개시된다. 송신 단말의 동작 방법은, 제1 재전송 방식에 기초하여 제1 데이터를 수신 단말에 전송하는 단계, 재전송 방식의 전환을 지시하는 제1 지시자 및 상기 제1 재전송 방식을 위해 예약된 자원의 재사용 여부를 지시하는 제2 지시자를 포함하는 SCI를 상기 수신 단말에 전송하는 단계, 및 상기 SCI에 의해 개시되는 제2 재전송 방식에 기초하여 제2 데이터를 상기 수신 단말에 전송하는 단계를 포함한다.
