Abstract:
(EN) The present invention relates to a method and apparatus for synchronization between electronic devices, and more particularly, to a synchronization method and apparatus for wireless communication between electronic devices. A method, which is a synchronization method in an electronic device for wireless communication with other electronic devices according to an embodiment of the present invention, comprises the steps of: when two or more reference sync signals are received within a predetermined period, checking whether the received sync signals have been synchronized; when the reference sync signals have not been synchronized, selecting a terminal for transmitting a reference sync signal which has the lowest rating or below among the received reference sync signals; when a terminal is selected as the reference sync signal transmission terminal, generating and transmitting a reference sync signal at a predetermined time point so as to have temporal orthogonality among ratings within a sync frame; and synchronizing the reference sync signal with the other electronic devices which transmit the reference sync signal.
(FR) La présente invention porte sur un procédé et un appareil pour la synchronisation entre des dispositifs électroniques, et plus particulièrement un procédé de synchronisation et un appareil pour la communication sans fil entre des dispositifs électroniques. Les étapes d'un procédé, lequel est un procédé de synchronisation dans un dispositif électronique pour la communication sans fil avec d'autres dispositifs électroniques selon un mode de réalisation de la présente invention, consistent : quand deux signaux de synchronisation de référence ou plus sont reçus dans une période préétablie, à vérifier si les signaux de synchronisation reçus ont été synchronisés ; quand les signaux de synchronisation de référence n'ont pas été synchronisés, à sélectionner un terminal permettant d'émettre un signal de synchronisation de référence qui a le niveau le plus bas ou inférieur parmi les signaux de synchronisation de référence reçus ; quand un terminal est sélectionné comme terminal d'émission de signal de synchronisation de référence, à générer et à émettre un signal de synchronisation de référence à un instant préétabli afin d'établir l'orthogonalité temporelle parmi les niveaux dans une trame de synchronisation ; et à synchroniser le signal de synchronisation de référence avec les autres dispositifs électroniques qui émettent le signal de synchronisation de référence.
(KO) 본 발명은 전자장치들간 동기화를 위한 방법 및 장치에 관한 것으로, 특히 전자장치들간 무선 통신을 위한 동기화 방법 및 장치에 관한 것이다. 본 발명의 일 실시예에 따른 방법은, 다른 전자장치와 무선 통신을 위한 전자장치에서 동기화 방법으로, 미리 설정된 주기 내에 둘 이상의 기준 동기 신호가 수신되는 경우 수신된 동기 신호들이 동기화 되어 있는지를 검사하는 단계; 상기 기준 동기신호들간 동기화되어 있지 않는 경우 상기 수신된 기준 동기 신호들 중 가장 낮은 등급 이하 등급의 기준 동기신호 송출 단말을 선출하는 단계; 상기 기준 동기신호 송출 단말로 선출될 시 동기 프레임 내에 각 등급간 시간적인 직교성을 갖도록 미리 설정된 시점에 기준 동기신호를 생성하여 송신하는 단계; 및 상기 기준 동기신호를 송출하는 다른 전자장치들과 기준 동기 신호를 동기화하는 단계를 포함할 수 있다.
