Abstract:
(EN) The present specification provides a beam failure recovery method in a wireless communication system. The beam failure recovery method performed by a terminal, according to the present specification, comprises the steps of: receiving, from a base station, control information associated with a candidate beam configuration for beam failure recovery; selecting, from RSs associated with identifying the candidate beam, an RS having a quality level that is at least a threshold value; and transmitting a beam failure recovery request to the base station on the basis of an uplink (UL) resource associated with the selected RS.
(FR) La présente invention concerne un procédé de reprise sur défaillance de faisceau dans un système de communication sans fil. Le procédé de reprise sur défaillance de faisceau mis en œuvre par un terminal, selon la présente invention, comprend les étapes consistant à : recevoir, en provenance d'une station de base, des informations de commande associées à une configuration de faisceau candidat pour une reprise sur défaillance de faisceau ; sélectionner, parmi des signaux de référence (RS) associés à l'identification du faisceau candidat, un RS ayant un niveau de qualité qui est supérieur ou égal à une valeur seuil ; et transmettre une demande de reprise sur défaillance de faisceau à la station de base sur la base d'une ressource de liaison montante (UL) associée au RS sélectionné.
(KO) 본 명세서는 무선 통신 시스템에서 빔 실패 복구(beam failure recovery) 방법을 제공한다. 본 명세서에서 단말에 의해 수행되는 빔 실패 복구 방법은, 상기 빔 실패 복구를 위한 후보 빔(candidate beam) 설정과 관련된 제어 정보를 기지국으로부터 수신하는 단계; 상기 후보 빔 식별과 관련된 RS들 중에서 상기 임계값 이상의 품질을 가지는 RS를 선택하는 단계; 및 상기 선택된 RS와 관련된 UL(uplink) 자원에 기초하여 빔 실패 복구 요청(beam failure recovery request)를 기지국으로 전송하는 단계를 포함하는 것을 특징으로 한다.
