技术领域
本公开实施例涉及通信技术领域，特别是指一种应用于5G系统的同步方法及装置。
背景技术
目前长期演进LTE中，同步参考符号占用固定的时频资源发送，频域资源是中心频点72个子载波。时域资源TDD与频域资源FDD略有不同，对于FDD，辅同步信号SSS位于#SF0和#SF5的倒数第二个符号，主同步信号PSS位于#SF0和#SF5的最后一个符号。对于TDD，辅同步信号SSS位于#SF0和#SF5的最后一个符号，主同步信号PSS位于特殊子帧的第三个符号。终端UE只需在相应时频位置检测同步符号从而获得小区同步。
LTE中，资源栅格是100KHz，终端每隔100KHz扫描同步符号，进行小区检测。同步符号的位置与中心频点是重合的。
在5G中，系统带宽很大，最大系统带宽不能少于80MHz，从复杂度和成本角度考虑，很有可能终端支持的带宽小于网络带宽。目前，标准化上同步符号如何发送还未确定，但是资源栅格(频点间隔)与同步符号发送的频域位置是相对关系，会对小区接入、同步的保持产生不利影响。
相关技术中针对5G系统存在如下技术问题：
1.如果同步符号发送间隔与中心频点间隔相同，而且同步符号的频域发送位置与小区的中心频点相同，通过同步符号资源位置即可获知中心频点。这种情况说明某个小区的同步符号只在系统带宽的固定一个频域资源上发送，如果该频域资源未被包括在终端被调度的资源内，终端如何继续保持同步成为问题。
2.如果同步符号发送间隔与中心频点间隔不同，在系统带宽内可能有多个同步符号发送位置，终端如何获知系统中心频点成为问题。
