Abstract

Se describen sistemas y metodologías que faciliten las búsquedas de celda en un ambiente de comunicaciones inalámbricas. Un dispositivo móvil puede emplear un buscador que puede detectar información de sincronización asociada respectivamente con los PSCs y celdas a fin de determinar la celda con la correlación más alta. El buscador puede detectar los SSCs, los cuales pueden incluir la detección de información de fase asociada, determinar el SSC con la correlación más alta, largo de CP, y/u otra información para facilitar la identificación de una celda deseada que tenga la señal más resistente para establecer comunicación entre el dispositivo móvil y la celda deseada. Los PSCs asociados respectivamente con las celdas pueden tener diferentes posiciones en las secuencias de símbolo, y los SSCs pueden variar de fase respectivamente en ángulos diferentes a fin de facilitar la detección e identificación de una celda(s), donde puede utilizarse un PSC como referencia de fase por el SSC asociado.
