Title:
SYNCHRONIZATION METHOD AND DEVICE BASED ON UNLICENSED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2019/169538
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the field of communications. Disclosed are a synchronization method and device based on an unlicensed spectrum, capable of effectively reducing the delay of a terminal device accessing a network and improving the system coverage capability. The specific solution is that: on the basis of an unlicensed spectrum resource, sending a synchronization signal and broadcast information in a frequency domain using a fixed channel, wherein the fixed channel occupies N channels, the N channels are adjacent, the bandwidth of each of the N channels is a first bandwidth, N is a positive integer greater than or equal to 2, and in a time unit in a time domain, and the duration occupied by the synchronization signal and broadcast information is T1, T1 being less than a preset duration. The embodiments of the present application are used in a synchronization process. The method provided by the embodiments of the present application can be applied to a communication system, such as V2X, LTE-V, V2V, Internet of vehicles, MTC, IoT, LTE-M, M2M, and Internet of things.
