Abstract:
(EN) Disclosed are a synchronization signal transmission method and a base station, in which beamforming of synchronization signals is performed in the following manner: a codebook is configured by defining a plurality of third precoders by connecting basic precoders which respectively correspond to a plurality of antenna subarrays, the synchronization signals are repeatedly transmitted to a terminal by applying the third precoders selected from the codebook to a synchronization sequence across a plurality of time intervals, and the plurality of antenna subarrays are independently controlled by first precoders respectively corresponding thereto.
(FR) La présente invention concerne un procédé d'émission de signal de synchronisation et une station de base, dans laquelle la formation de faisceaux de signaux de synchronisation est effectuée de la manière suivante : un livre de codes est configuré en définissant une pluralité de troisièmes précodeurs en connectant des précodeurs de base qui correspondent respectivement à une pluralité de sous-réseaux d'antenne, les signaux de synchronisation sont émis de façon répétée à un terminal par l'application des troisièmes précodeurs sélectionnés à partir du livre de codes à une séquence de synchronisation à travers une pluralité d'intervalles de temps, et la pluralité de sous-réseaux d'antenne sont commandés indépendamment par des premiers précodeurs qui leur correspondent respectivement.
