Title (EN) BASE STATION SYNCHRONIZATION IN A WCDMA SYSTEM
(FR) SYNCHRONISATION DE STATION DE BASE DANS UN SYSTEME WCDMA
Abstract: front page image
(EN) A wideband code division multiple access system supports asynchronous operation, with each base station having its own time reference. Substantial benefits may be realized by operating the WCDMA system in a quasi-synchronous mode, in which the base stations broadcast the relative time difference between their time references and the time references of their neighbor bases stations. The WCDMA system supports techniques for measuring the relative time difference.
(FR) L'invention concerne un système à accès multiples par répartition de code et à large bande prenant en charge des opérations asynchrones, chaque station de base étant pourvue d'une référence de temps propre. Il est possible de réaliser des bénéfices substantiels peuvent être réalisés, en faisant fonctionner le système WCDMA dans un mode quasi-synchrone, dans lequel les stations de base diffusent la différence de temps relative entre leurs références de temps et les références de temps de leurs stations de base voisines. Le système WCDMA prend en charge des techniques de mesure des différences de temps relatives.
