Abstract

본 발명은 밀리미터웨이브(mmWave)를 지원하는 무선 접속 시스템에 관한 것으로, 링크 단절을 피하기 위해 빠른 폴백을 수행하는 방법들 및 이를 지원하는 장치들을 제공한다. 본 발명의 일 실시예로서 밀리미터웨이브(mmWave)를 지원하는 무선접속 시스템에서 레가시 기지국이 mmWave 단말의 빠른 폴백을 지원하는 방법은: mmWave 단말로부터 빠른 폴백을 요청하는 제1 폴백 요청 메시지를 수신하는 단계와 제1 폴백 요청 메시지 수신 후 폴백 여부를 결정하기 위한 폴백 타이머를 동작하는 단계와 폴백 타이머 내에 mmWave 기지국으로부터 빠른 폴백을 요청하는 제2 폴백 요청 메시지가 수신되었는지 여부를 판단하는 단계를 포함할 수 있다.
