Abstract

Las modalidades de esta solicitud proporcionan un método y aparato de transmisión de señal de sincronización. De acuerdo con el método y el aparato, un primer dispositivo genera una primera secuencia de sincronización y/o a segunda secuencia de sincronización, en donde la primera secuencia de sincronización es diferente de cualquier secuencia de un tercer conjunto de secuencias de sincronización, y/o la segunda secuencia de sincronización es diferente de cualquier secuencia de un cuarto conjunto de secuencias de sincronización. El método y aparato puede reducir de manera eficaz la interferencia entre una señal de sincronización transmitida de acuerdo con el método y el aparato y una señal de sincronización en un enlace celular de un nuevo sistema de radio, mejoran el desempeño de sincronización entre dispositivos, y se pueden aplicar a V2X, LTE-V, V2V, un internet de vehículos, MTC, el IoT, LTE-M, M2M, el internet de cosas, y similar.
