Abstract

Se provee técnicas para el diseño de señales de sincronización para la operación en banda estrecha, que se puede usar para el despliegue de ser único / en banda / banda de guarda. Se provee un método de ejemplo para operaciones que se pueden realizar mediante una estación base (BS). En general el método de ejemplo incluye generar una señal de sincronización primaria (PSS) utilizando una primera secuencia de código y un código encubierto aplicado a la primera secuencia de códigos sobre un primer número de símbolos dentro de una o más subtramas, generar una señal de sincronización secundaria (SSS) en base a una segunda secuencia de código sobre un segundo número de símbolos dentro de una o más subtramas, y transmitir la PSS y la SSS en la primera y segunda subtrama a un primer tipo de un equipo de usuario (UE) que comunica en una o más regiones de banda estrecha de mayor ancho de banda de sistema.
