Abstract

Se describen métodos, sistemas y dispositivos para comunicación inalámbrica. Una estación base puede difundir una señal de sincronización utilizando una porción de banda estrecha de un ancho de banda de una celda. La señal de sincronización puede incluir una secuencia repetida durante varios períodos de símbolos utilizando un código de cobertura para soportar la adquisición de celdas de eficiencia energética. Un equipo de usuario (UE) que recibe la señal de sincronización puede determinar información de frecuencia y tiempo para una celda al realizar una combinación ponderada y acumulación de procedimientos de autocorrelación de baja complejidad y de correlación cruzada en la señal de sincronización. Los procedimientos de correlación de complejidad reducida pueden habilitarse basándose en el uso del código de cobertura y una secuencia de base. En algunos casos, la correlación cruzada puede realizarse a múltiples tasas de muestreo. El uso del código de cobertura dentro de la señal de sincronización también puede soportar procedimientos de correlación que utilizan actualizaciones repetitivas o recursivas, que pueden permitir una complejidad computacional adicional reducida con respecto a otros procedimientos de búsqueda de celdas.
