Title (EN) METHODS AND APPARATUSES FOR USER EQUIPMENT ASSISTED TIME AND FREQUENCY SYNCHRONIZATION OF SMALL CELLS
(FR) PROCÉDÉS ET APPAREILS UTILISÉS POUR ASSURER LA SYNCHRONISATION TEMPS/FRÉQUENCE ASSISTÉE PAR UN ÉQUIPEMENT UTILISATEUR, À DE PETITES CELLULES
Abstract:
(EN) Aspects of the present disclosure provide a user equipment (UE) assisted synchronization method in which a small cell can request and obtain time and frequency offset information from one or more UEs currently associated with the small cell, and the small cell can discipline its clock drift accordingly.
(FR) Des aspects de la présente invention concernent un procédé de synchronisation assistée par un équipement utilisateur (UE) dans lequel une petite cellule peut demander et obtenir des informations de décalage de temps et de fréquence à partir d'un ou plusieurs équipements utilisateurs (UE) actuellement associés à la petite cellule, laquelle petite cellule peut régler sa dérive d'horloge en conséquence.
