Disclosed is a method by which a terminal performs grant-free-based data communication in a wireless communication system, comprising the steps of: receiving configuration information about grant-free transmission resources; selecting, on the basis of the configuration information, a transmission resource for transmitting a physical uplink shared channel (PUSCH); transmitting uplink control information including scheduling information about the selected transmission resource; and transmitting the PUSCH through the selected transmission resource. La présente invention concerne un procédé selon lequel un terminal réalise une communication de données sur une base sans autorisation dans un système de communication sans fil. Le procédé comprend les étapes consistant à : recevoir des informations de configuration au sujet de ressources de transmission sans autorisation ; sélectionner, sur la base des informations de configuration, une ressource de transmission pour transmettre un canal physique partagé de liaison montante (PUSCH) ; transmettre des informations de commande de liaison montante comprenant des informations de planification au sujet de la ressource de transmission sélectionnée ; et transmettre le PUSCH par le biais de la ressource de transmission sélectionnée. 본 개시는 비승인 전송 자원에 대한 설정 정보를 수신하는 단계; 상기 설정 정보에 기초하여 PUSCH(Physical Uplink Shared CHannel)를 송신하기 위한 전송 자원을 선택하는 단계;상기 선택한 전송 자원에 대한 스케줄링 정보를 포함하는 상향링크 제어 정보(Uplink Control Information)를 전송하는 단계; 및 상기 선택한 전송 자원을 통해 상기 PUSCH를 전송하는 단계를 포함하는 단말의 무선 통신 시스템에서의 비승인(Grant-free) 기반 데이터 통신 방법을 제공한다.
