Abstract

Se describen sistemas y métodos relacionados con una Señal de Sincronización Primaria de banda estrecha (NB-PSS) y una Señal de Sincronización Secundaria de banda estrecha (NB-SSS). En algunas modalidades, una estación base en una red inalámbrica comprende un procesador y almacenamiento que almacena instrucciones ejecutables por el procesador por lo que la estación base es operable para transmitir una NB-PSS y una NB-SSS en una porción de banda estrecha del ancho de banda del sistema de enlace descendente. La NB-PSS y la NB-SSS se transmiten de manera tal que más de dos apariciones de la NB-PSS y más de dos apariciones de la NB-SSS se transmiten a lo largo de un intervalo de tiempo definido, cada aparición de la NB-PSS se transmite a través de múltiples símbolos contiguos de multiplexación por división de frecuencia ortogonal (OFDM) y cada aparición de la NB-SSS se transmite sobre múltiples símbolos OFDM contiguos, y cada aparición de la NB-SSS proporciona una indicación de una ubicación de la aparición de al NB-SSS dentro del intervalo de tiempo definido.
