Description

同步信号块的传输方法、网络设备及用户设备
相关申请的交叉引用
本申请主张在2017年4月28日在中国提交的中国专利申请No.201710296851.9的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种同步信号块的传输方法、网络设备及用户设备。
背景技术
终端在与核心网进行通信之前，需要进行小区搜索，找到终端所处位置所属的小区，并与该小区进行同步，接收并解码与该小区进行通信和正常工作的必要信息。具体地，终端通过检测在特定位置的主同步信号(Primary Synchronized Signal，以下简称：PSS)和辅同步信号(Secondary Synchronized Signal，以下简称：SSS)，获得下行同步和小区的物理层小区身份信息(Cell ID)，然后通过接收物理广播信道(Physical Broadcast Channel，以下简称：PBCH)信号，获取必要的小区系统信息。
在长期演进(Long Term Evolution，以下简称：LTE)系统中，为了辅助小区搜索，每个下行分量载波上都有两个特殊的信号PSS和SSS，PSS由长度为63的Zadoff-Chu序列在两端以5个零进行扩展，最后映射到中间6个物理资源块(Physical Resource Block，以下简称：PRB)上得到。与PSS类似，SSS也是占据了中间的6个PRB。PBCH用于传输有限的必要小区系统信息，由于接收PBCH时，终端可能还不知道下行小区的带宽，因此，无论小区带宽为多少，PBCH传输均限定在中间的72个子载波上。也就是说，PSS/SSS和PBCH在频域上所占资源块数目一样，被映射到相同的频域位置。在时域方向，FDD模式下，PSS在第0子帧和第5子帧的第一个时隙(slot)的最后一个符号(symbol)，SSS则在同一时隙上紧邻最后那个符号的位置上传输，即SSS位于PSS之前的那个符号上；TDD模式下，PSS在第1子帧和第6子 帧的第三个符号上传输，即下行导频DwPTS域内，SSS则在第0子帧和第五子帧的最后一个符号上传输，即SSS位于PSS之前三个符号位置上传输。而对于PBCH，无论是FDD还是TDD，均在第0子帧第2个时隙的前4个符号上传输。因此，在FDD中，PBCH紧跟在第0子帧的PSS和SSS之后。
在新空口(New Radio，以下简称：NR)系统的设计中，使用NR-PSS和NR-SSS辅助小区搜索，使用NR-PBCH发送必要的系统信息。NR-PSS和NR-SSS的序列长度均为127，需要占用的频域资源为12个NR-PRB，NR-PBCH的带宽是288个子载波，即288/12＝24个PRB，因此，NR-PSS/NR-SSS在频域上所占的资源块数目与NR-PBCH不同，LTE系统中的频域资源映射关系无法适用于NR系统。
