Abstract:
(EN) The present invention relates to a method for avoiding collision in a synchronous wireless communication system and, more specifically, to a method for efficiently avoiding collision when a resource is used by and allocated to a large number of mobile terminals, in a synchronous wireless distributed-communication system. A collision avoidance method according to the present invention may comprise the steps of: determining a slot where a terminal performs transmission at a main frequency channel; performing contention in a slot previous to the determined slot by using a contention agency channel having a different frequency from the main frequency channel; and using the selected slot of the main frequency channel when the terminal has won the contention.
(FR) La présente invention concerne un procédé pour éviter une collision dans un système de communication sans fil synchrone et, plus spécifiquement, un procédé pour éviter efficacement une collision lorsqu'une ressource est utilisée par et attribuée à un grand nombre de terminaux mobiles, dans un système de communication distribué sans fil synchrone. Selon la présente invention, un procédé d'évitement de collision peut comprendre les étapes consistant à : déterminer un intervalle dans lequel un terminal effectue une transmission au niveau d'un canal de fréquence principal ; effectuer une contention dans un intervalle précédent l'intervalle déterminé à l'aide d'un canal d'agence de contention comportant une fréquence différente du canal de fréquence principal ; et utiliser l'intervalle sélectionné du canal de fréquence principal lorsque le terminal a gagné la contention.
(KO) 본 발명은 동기된 무선 통신 시스템에서 충돌을 회피하는 방법에 대한 것으로 보다 상세하게는 동기된 무선 분산 통신 시스템에서 대규모 이동 단말이 자원을 사용하고 할당 때, 효율적으로 충돌을 회피하는 방법에 대한 것이다. 이에 따른, 충돌 회피 방법은, 단말이 주 주파수 채널에서 송신할 슬롯을 결정하는 단계, 상기 결정된 슬롯의 앞 슬롯에서 주 주파수 채널과 주파수가 다른 경쟁 대행 채널을 이용하여 경쟁을 수행하는 단계, 상기 경쟁에서 이길 경우에 상기 선택한 주 주파수 채널의 슬롯을 사용하는 단계를 포함할 수 있다.
