Summary:A random access communication method according to the technical idea of the present invention includes a step of receiving a first retransmission packet retransmitted to a different frame from a first initial transmission packet, a step of determining whether the first retransmission packet is successfully received without collision with another packet, and a step of removing the interference of the first initial transmission packet that was transmitted in the previous frame of the first retransmission packet when the first retransmission packet is successfully received. It is possible to efficiently resolve a packet collision between wireless communication devices. 본 발명의 기술적 사상에 따른 랜덤 액세스 통신 방법은 제1 최초전송 패킷과 서로 다른 프레임에 재전송된 제1 재전송 패킷을 수신하는 단계, 상기 제1 재전송 패킷이 다른 패킷과의 충돌 없이 성공적으로 수신되었는지 여부를 판단하는 단계 및 상기 제1 재전송 패킷이 성공적으로 수신된 경우, 상기 제1 재전송 패킷의 이전 프레임에 전송되었던 상기 제1 최초전송 패킷의 간섭을 제거하는 단계를 포함한다.
