Abstract:
(EN) A user equipment: transmits, on a cell, a first random access channel (RACH) preamble as a first message in a random access procedure; receives a first random access response (RAR) to the first RACH preamble, as a second message in the random access procedure; transmits a third message in the random access procedure on the basis of the second message; and receives a fourth message in the random access procedure. The third message may include information on subcarrier spacing candidates supported by the user equipment. The fourth message may include information on a particular subcarrier spacing to be used by the user equipment.
(FR) Un équipement utilisateur : transmet, sur une cellule, un premier préambule de canal d'accès aléatoire (RACH, "random access channel") en tant que premier message dans une procédure d'accès aléatoire; reçoit une première réponse d'accès aléatoire (RAR, "random access response") au premier préambule de RACH, en tant que second message dans la procédure d'accès aléatoire; transmet un troisième message dans la procédure d'accès aléatoire sur la base du deuxième message; et reçoit un quatrième message dans la procédure d'accès aléatoire. Le troisième message peut comprendre des informations sur des candidats d'espacement de sous-porteuse pris en charge par l'équipement utilisateur. Le quatrième message peut comprendre des informations sur un espacement de sous-porteuse particulier devant être utilisé par l'équipement utilisateur.
(KO) 사용자기기가 임의 접속 과정의 제1 메시지로서 제1 임의 접속 채널(random access channel, RACH) 프리앰블을 셀 상에서 전송; 상기 임의 접속 과정의 제2 메시지로서 상기 제1 RACH 프리앰블에 대한 제1 임의 접속 응답(random access response, RAR)을 수신; 상기 제2 메시지를 기반으로 상기 임의 접속 과정의 제3 메시지를 전송; 및 상기 임의 접속 과정의 제4 메시지를 수신한다. 상기 제3 메시지는 상기 사용자기기가 지원하는 부반송파 간격 후보에 관한 정보를 포함할 수 있다. 상기 제4 메시지는 상기 사용자기기가 사용할 특정 부반송파 간격에 관한 정보를 포함할 수 있다.
