Abstract
(EN)
The present invention may provide a method for selecting a carrier by a terminal by using a V2X sidelink in a wireless communication system. The method for selecting a carrier by a terminal may comprise the steps of: triggering transmission carrier reselection; calculating respective CBRs of available carriers; and performing sidelink communication through an exceptional pool when calculated values for the respective CBRs of the available carriers each exceed a threshold.
(FR)
La présente invention concerne un procédé de sélection d'une porteuse par un terminal à l'aide d'une liaison latérale V2X dans un système de communication sans fil. Le procédé de sélection d'une porteuse par un terminal peut comprendre les étapes consistant à : déclencher une resélection de porteuse de transmission; calculer des CBR respectifs de porteuses disponibles; et réaliser une communication de liaison latérale par l'intermédiaire d'un groupe exceptionnel lorsque des valeurs calculées pour les CBR respectifs des porteuses disponibles dépassent chacune un seuil.

본 발명은 무선 통신 시스템에서 V2X 사이드링크를 이용하여 단말이 캐리어를 선택하는 방법을 제공할 수 있다. 이때, 단말이 캐리어를 선택하는 방법은 전송 캐리어 재선택을 트리거링하는 단계, 이용 가능한 각각의 캐리어에 대한 CBR을 측정하는 단계, 이용 가능한 캐리어에 대한 각각의 CBR 측정 값이 모두 임계값을 초과하는 경우, 예외 풀(Exceptional Pool)을 통해 사이드링크 통신을 수행하는 단계를 포함할 수 있다.
