Abstract
RESUMEN Aspectos de la presente divulgación proporcionan técnicas para el diseño de señales de sincronización para una operación de banda estrecha y otros sistemas de nuevo comienzo con base en OFDM, tales como sistemas mejorados de portadora de componentes (eCC). Se proporciona un método de ejemplo para las operaciones que puede realizar una BS para generar y transmitir una PSS de doble capa, y, correspondientemente, técnicas para detección por parte de un UE de la PSS de doble capa. La PSS se puede generar utilizando una cubierta de código binario y al menos una secuencia aplicada a un número de símbolos dentro de una o más subtramas de una trama.
