Abstract
본 발명은 무선 패킷 통신, 특히 근거리 무선 통신 시스템에서, 하나의 단말이 여러 개의 단말과 동시에 통신하고자 할 때, 데이터를 송/수신 하기 위한 방법에 대한 것이다. 본 발명의 송신 단말이 복수 개의 수신 단말에 데이터를 송신하는 방법은, 복수 개의 수신 단말에 송신할 서로 다른 데이터들 중 최대 길이를 갖는 데이터를 결정하는 단계, 최대 길이를 갖는 데이터의 길이 정보를 획득하는 단계, 최대 길이를 갖는 데이터의 길이 정보를 포함하는 시그널 필드를 생성하는 단계 및 시그널 필드를 복수 개의 수신 단말에 송신하는 단계를 포함한다. 본 발명에 따르면 하나의 단말이 여러 개의 통신경로를 이용하여 여러 개의 단말에 동시에 데이터를 전송하고 그에 대한 Ack을 받을 때, 수신불가 구역이 발생하지 않도록 하여 원활한 통신이 가능하도록 할 수 있는 효과가 있다.
