Abstract

IEEE 802.11 무선랜 환경에서의 통신 방법이 개시된다. 본 발명에 따른 IEEE 802.11 무선랜 환경의 스테이션에서의 통신 방법은, 상기 스테이션에서 다른 스테 이션을 목적지로 하는 트래픽이 발생하는 경우, AP(access point)와 통신하기 위해 사용되는 BSS(basic service set) 채널 외의 무선 채널인 세컨더리 채널로 직접 링 크를 설정하기 위한 협상을 상기 다른 스테이션과 수행하는 단계; 상기 협상 수행 결과 상기 세컨더리 채널로 직접 링크를 설정하기로 협상이 성공하면 상기 스테이 션의 동작 채널을 상기 BSS 채널에서 상기 세컨더리 채널로 스위칭하는 단계; 및 상기 세컨더리 채널을 통하여 상기 다른 스테이션으로 상기 발생된 트래픽의 데이 터를 송신하는 단계를 포함하는 것을 특징으로 한다. 이러한 본 발명에 의하면, IEEE 802.11 무선랜 환경에서 다중 채널을 이용하여 스테이션과 AP 간에 통신하고 스테이션들 간에 직접 링크를 설정할 수 있다.
