Abstract

Un método (400, 500) y aparato para la sincronización de un dispositivo de comunicaciones inalámbricas (300) mediante múltiples canales de sincronización. El dispositivo de comunicaciones inalámbricas (300) puede realizar una búsqueda de celda inicial (420). Durante la búsqueda de celda inicial, puede adquirirse un símbolo de sincronización primaria (430) sólo de un canal central de sincronización de los múltiples canales de sincronización. Los múltiples canales de sincronización pueden incluir el canal central de sincronización y múltiples canales de sincronización secundaria. El símbolo de sincronización primaria puede asociarse con los múltiples canales de sincronización secundaria. Puede ejecutarse una traducción de frecuencia (460) para cambiar un canal receptor a fin de adquirir uno de los canales de sincronización secundaria.
