Title (EN) METHOD AND DEVICE FOR TRACKING SYNCHRONIZATION
(FR) PROCÉDÉ ET DISPOSITIF DE SUIVI DE SYNCHRONISATION
(KO) 동기를 트랙킹하는 방법 및 장치
Abstract:
(EN) Provided are a method and device for tracking synchronisation between apparatuses in a wireless communication system. A receiving apparatus receives, from a transmitting apparatus, a tracking signal in a subframe, and the received tracking signal is used in order to estimate the timing offset between the transmitting apparatus and the receiving apparatus. The tracking signal is received in the last OFDM symbol of the subframe, and the last OFDM symbol contains a sequence that is repeated N (N>1) times.
(FR) L'invention concerne un procédé et un dispositif de suivi de la synchronisation entre des appareils dans un système de communication sans fil. Un appareil récepteur reçoit d'un appareil émetteur un signal de suivi dans une sous-trame, et le signal de suivi reçu est utilisé pour estimer le décalage de synchronisation entre l'appareil émetteur et l'appareil récepteur. Le signal de suivi est reçu dans le dernier symbole OFDM de la sous-trame, et le dernier symbole OFDM de la sous-trame contient une séquence qui est répétée N fois (N>1).
(KO) 무선 통신 시스템에서 기기간 동기를 트랙킹하는 방법 및 장치가 제공된다. 수신기가 전송기로부터 서브프레임에서 트랙킹 신호를 수신하고, 상기 수신된 트랙킹 신호를 이용하여 상기 전송기와 상기 수신기간 타이밍 오프셋을 추정한다. 상기 트랙킹 신호는 상기 서브프레임의 마지막 OFDM 심벌에서 수신되고, 상기 마지막 OFDM 심벌 내에서 N (N>1) 회 반복되는 시퀀스를 포함한다.
