Abstract

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 B를 수신하기 위한 RNTI(Radio Network Temporary Identifier)는, 상기 RACH preamble과 관련된 RACH occasion 및 상기 RACH occasion에 관련된 오프셋에 기초하여 생성될 수 있다.
