Abstract
(EN)
Disclosed are a synchronization signal transmission method and a base station. In the synchronization signal transmission method, a code book, comprising a plurality of second precoders defined by the weighted sums of a plurality of first precoders, is defined, a first synchronization signal, to which applied is any second precoder selected from the code book, is transmitted to a terminal in a first time interval, and a second synchronization signal, to which applied is another second precoder selected from the code book, is transmitted to the terminal in a second time interval. The first synchronization signal and second synchronization signal are used in the synchronization with the base station.

L'invention concerne un procédé de transmission de signal de synchronisation, et une station de base. Le procédé de transmission de signal de synchronisation selon l’invention comprend les étapes suivantes : un livre de code, contenant une pluralité de seconds précodeurs définis par les sommes pondérées d'une pluralité de premiers précodeurs, est défini ; un premier signal de synchronisation auquel est appliqué un second précodeur sélectionné dans le livre de codes, est transmis à un terminal durant un premier intervalle de temps ; et un second signal de synchronisation auquel est appliqué un second précodeur différent sélectionné dans le livre de codes, est transmis au terminal durant un second intervalle de temps. Le premier signal de synchronisation et le second signal de synchronisation sont utilisés dans la synchronisation avec la station de base.
