Abstract

Se describen técnicas para determinar la sincronización de una célula en un sistema de comunicaciones inalámbricas. Un equipos del usuario (UE) puede obtener muestras recibidas que incluyen al menos una señal de sincronización generada con base en una identidad celular (ID) de una célula. El UE puede correlacionar las muestras recibidas con al menos una señal de sincronización en el dominio temporal a diferentes desplazamientos temporales para obtener energías para múltiples hipótesis de sincronización. El UE puede identificar al menos un pico detectado con base en las energías para las múltiples hipótesis de sincronización. El UE entonces puede actualizar un conjunto de picos candidato con base en el al menos un pico detectado y puede identificar un pico candidato con una intensidad de señal que exceda la intensidad de señal de un pico que será rastreado. El UE puede proporcionar la sincronización del pico candidato identificado como la sincronización celular.
