Abstract
(EN)
The present disclosure provides a method for performing a random access channel (RACH) procedure by a terminal in a wireless communication system. Specifically, the method may comprise: transmitting message A including a physical random access channel (PRACH) preamble and a physical uplink shared channel (PUSCH); and receiving message B including contention resolution information, in response to the message A, wherein information on retransmission of the message A is included in a medium access control protocol data block (MAC PDU) for a random access response (RAR) related to the message B.
(FR)
L'invention concerne un procédé permettant d'effectuer une procédure de canal d'accès aléatoire (RACH) au moyen d'un terminal dans un système de communication sans fil. Plus précisément, le procédé peut comprendre : la transmission d'un message A comprenant un préambule de canal d'accès aléatoire physique (PRACH) et un canal partagé de liaison montante physique (PUSCH) ; et la réception d'un message B comprenant des informations de résolution de contention, en réponse au message A ; des informations sur la retransmission du message A étant comprises dans un bloc de données de protocole de commande d'accès au support (MAC PDU) pour une réponse d'accès aléatoire (RAR) associée au message B.
(KO)
본 개시는 무선 통신 시스템에서 단말이 임의 접속 과정(Random Access Channel Procedure; RACH Procedure)을 수행하는 방법을 개시한다. 특히, 상기 방법은 PRACH(Physical Random Access Channel) preamble 및 PUSCH(Physical Uplink Shared Channel)를 포함하는 메시지 A를 전송하고, 상기 메시지 A에 대한 응답으로, 경쟁 해결(contention resolution) 정보를 포함하는 메시지 B를 수신하는 것을 포함하고, 상기 메시지 B와 관련된 랜덤 액세스 응답(Random Access Response; RAR)을 위한 MAC PDU(Medium Access Control Protocol Data Block)에 상기 메시지 A의 재전송에 대한 정보가 포함될 수 있다.
