Abstract
Los aspectos de la presente descripción proporcionan técnicas para el diseño de señales de sincronización para la operación de banda estrecha, las cuales pueden utilizarse para la implementación autónoma/en banda/banda de protección. Se proporciona un método ejemplar para operaciones que pueden realizarse por una estación base (BS). El método ejemplar generalmente incluye generar una señal de sincronización primaria (PSS) utilizando una primera secuencia de códigos y un código de cobertura aplicado a la primera secuencia de códigos sobre una primera cantidad de símbolos dentro de una o más subtramas, generar una señal de sincronización secundaria (SSS) basada en una segunda secuencia de códigos sobre una segunda cantidad de símbolos dentro de una o más subtramas y transmitir la PSS y la SSS en la primera y segunda subtramas a un primer tipo de un equipo de usuario (UE) que se comunica en una o más regiones de banda estrecha de ancho de banda más amplio de sistema.
