Abstract

Se proporcionan un método de transmisión de señal de sincronización, un dispositivo extremo de transmisión y un dispositivo extremo de recepción. Se diseña una posición candidata de dominio de frecuencia (también denominada cuadricula SS) de señal de sincronización en una banda de frecuencia sin licencia, se reduce la complejidad de búsqueda de célula inicial y también se reduce el impacto, en los otros canales en una subbanda, de la posición de acceso inicial de una célula en la banda de frecuencia sin licencia a un bloque de señal de sincronización en la subbanda. El método comprende: un dispositivo de extremo de transmisión que envía un bloque de señal de sincronización en una primera posición de dominio de frecuencia, en donde la primera posición de dominio de frecuencia se ubica en una posición candidata de dominio de frecuencia de una señal de sincronización, y cada subbanda de MHz comprende al menos una de las posiciones candidatas de dominio de frecuencia de señal de sincronización.
