(KO) 무선 통신 시스템에서 단말 간 직접 통신에 기반한 단말 간 거리 측정 방법 및 이를 위한 장치
Abstract: front page image
(EN)A method by which a terminal calculates a distance to a counterpart terminal by using device-to-device direct communication in a wireless communication system is disclosed. Specifically, the method comprises the steps of: receiving a synchronization reference signal from a cluster head and receiving a first discovery signal from the counterpart terminal; calculating a first difference value between a reception time of the first discovery signal and a reception time of the synchronization reference signal; receiving, from the counterpart terminal, information on a second difference value between a reception time in the counterpart terminal of a second discovery signal transmitted from the terminal and a reception time of the synchronization reference signal in the counterpart terminal; and calculating a distance between the terminal and the counterpart terminal on the basis of a sum of the first difference value and the second difference value.
(FR)L'invention concerne un procédé par lequel un terminal calcule une distance à un terminal homologue en utilisant une communication directe de dispositif à dispositif dans un système de communications sans fil. Le procédé comporte particulièrement les étapes consistant à: recevoir un signal de référence de synchronisation provenant d'une tête de grappe et recevoir un premier signal de découverte en provenance du terminal homologue; calculer une première valeur d'écart entre un instant de réception du premier signal de découverte et un instant de réception du signal de référence de synchronisation; recevoir, en provenance du terminal homologue, des informations sur une deuxième valeur d'écart entre un instant de réception sur le terminal homologue d'un deuxième signal de découverte émis à partir du terminal et un instant de réception du signal de référence de synchronisation sur le terminal homologue; et calculer une distance entre le terminal et le terminal homologue sur la base d'une somme de la première valeur d'écart et de la deuxième valeur d'écart.
(KO)본 출원에서는 무선 통신 시스템에서 단말이 단말 간 직접 통신을 이용하여 상대 단말과의 거리를 산출하는 방법이 개시된다. 구체적으로, 상기 방법은, 클러스터 헤드로부터 동기 기준 신호를 수신하고, 상대 단말로부터 제 1 디스커버리 신호를 수신하는 단계; 상기 제 1 디스커버리 신호의 수신 시간과 상기 동기 기준 신호의 수신 시간과의 제 1 차이 값을 산출하는 단계; 상기 상대 단말로부터, 상기 단말로부터 송신된 제 2 디스커버리 신호의 상기 상대 단말에서의 수신 시간과 상기 동기 기준 신호의 상기 상대 단말에서의 수신 시간과의 제 2 차이 값에 대한 정보를 수신하는 단계; 및 상기 제 1 차이 값 및 상기 제 2 차이 값의 합에 기반하여, 상기 단말과 상기 상대 단말과의 거리를 산출하는 단계를 포함하는 것을 특징으로 한다.
