Abstract
(EN)
The present disclosure provides a method of transmitting/receiving a signal for a random access channel procedure (RACH procedure) by a terminal in a wireless communication system. Specifically, the method may comprise: receiving a synchronization signal/physical broadcast channel block (SS/PBCH block); acquiring system information from a PBCH included in the SS/PBCH block; transmitting message A including a physical uplink shared channel (PUSCH) and a physical random access channel (PRACH) preamble on the basis of the system information; and receiving message B including contention resolution information as a response to message A, wherein information associated with retransmission of message A is included in a medium access control protocol data block (MAC PDU) for a random access response (RAR) relating to message B.

La présente invention concerne un procédé d'émission/réception d'un signal pour une procédure de canal d'accès aléatoire (procédure RACH) par un terminal dans un système de communication sans fil. Spécifiquement, le procédé peut comporter les étapes consistant à: recevoir un bloc de signal de synchronisation/canal physique de diffusion (bloc de SS/PBCH); acquérir des informations de système à partir d'un PBCH compris dans le bloc de SS/PBCH; émettre un message A comprenant un canal physique partagé de liaison montante (PUSCH) et un préambule de canal physique d'accès aléatoire (PRACH) sur la base des informations de système; et recevoir un message B comprenant des informations de résolution de concurrence en tant que réponse au message A, des informations associées à la réémission 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) se rapportant au message B.

본 개시는 무선 통신 시스템에서 단말이 임의 접속 과정(Random Access Channel Procedure; RACH Procedure)을 수행하기 위한 신호를 송수신하는 방법을 개시한다. 특히, 상기 방법은 SS/PBCH 블록(Synchronization Signal/Physical Broadcast Channel Block)을 수신하고, 상기 SS/PBCH 블록에 포함된 PBCH로부터 시스템 정보를 획득하며, 상기 시스템 정보에 기반하여, 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.
