Title (EN) WIRELESS COMMUNICATION DEVICE AND METHOD THEREIN FOR TIME SYNCHRONIZATION IN A WIRELESS COMMUNICATION NETWORK
(FR) DISPOSITIF DE COMMUNICATION SANS FIL ET PROCÉDÉ ASSOCIÉ POUR LA SYNCHRONISATION TEMPORELLE DANS UN RÉSEAU DE COMMUNICATIONS SANS FIL
Abstract:
(EN) A wireless communication device and method therein for time synchronization in a wireless communication network are disclosed. The wireless communication device determines a first timing (tc) by performing a coarse time synchronization based on a synchronization signal received by the wireless communication device, wherein the received synchronization signal is sampled either in an original sampling rate or a reduced sampling rate. The wireless communication device determines a second timing (tf) by performing a fine time synchronization based on the determined first timing (tc) and the received synchronization signal.
(FR) L'invention concerne un dispositif de communication sans fil et un procédé associé pour la synchronisation temporelle dans un réseau de communication sans fil. Le dispositif de communication sans fil détermine une première base de temps (tc) en réalisant une synchronisation temporelle approximative sur la base d'un signal de synchronisation reçu par le dispositif de communication sans fil. Le signal de synchronisation reçu est échantillonné soit à une fréquence d'échantillonnage originale, soit à une fréquence d'échantillonnage réduite. Le dispositif de communication sans fil détermine une deuxième base de temps (tf) en réalisant une synchronisation temporelle précise sur la base de la première base de temps (tc) déterminée et du signal de synchronisation reçu.
