Title
(KO) 무선랜 통신 시스템의 다중 링크(Multi-Link)에서 블록 에크를 수행하는 방법 및 장치
Abstract
(KO)
본 발명은 다중 링크(multi-link) 동작을 지원하는 WLAN(Wireless Local Area Network)에서 제1 통신 노드의 동작 방법으로, 제2 통신 노드로 복수의 프레임들을 전송하기 위한 제1 링크의 제1 전송 윈도우 크기(Transmit window size)를 설정하는 단계, 상기 제1 링크를 통하여 상기 복수의 프레임들을 전송하는 단계, 제2 링크에서의 채널 센싱을 통하여 검출된 채널의 상태가 아이들(Idle) 상태인 경우, 상기 채널에 전송 기회(Transmit Opportunity, TXOP)를 설정하는 단계 및 상기 전송 기회가 설정된 경우, 상기 제2 통신 노드와 상기 복수의 프레임들을 전송하기 위한 제2 전송 윈도우 크기를 합의(agreement)하는 단계를 포함한다. 따라서 통신 시스템의 성능을 향상시킬 수 있다.
