Description

一种信息确定及配置方法、装置、计算机存储介质 技术领域
本发明涉及无线通信技术领域,尤其涉及一种信息确定及配置方法、装置、计算机存储介质。
背景技术
在长期演进(LTE,Long Term Evolution)系统中,小区公共参考信号(CRS,Cell-specific Reference Signal)在系统带宽内都存在,因此其带宽较大,并且其时域密度较密,终端可以使用CRS(和/或同步信号)获得较好的时频同步性能(timing/frequency tracking,或者timing/frequency synchronization)。
在新空口(NR,New Radio)系统中,同步信号块(SSB,Synchronization Signal Block)(包括主同步信号(PSS,Primary Synchronization Signal)、辅同步信号(SSS,Secondary Synchronization Signal)、物理广播信道(PBCH,Physical Broadcast Channel))只占用部分带宽,并且时域密度也比LTE的CRS密度小,因此可以用于粗同步,在一些需要更高精度时频同步时,无法达到要求。而NR系统中也不存在CRS信号,因此提出了一个新的信号同步参考信号(TRS,tracking Reference Signal)。在最终的设计中,TRS信号通过以下方式来实现,TRS在协议中的官方名字是CSI-RS for tracking:1)一组周期性的CSI-RS资源(CSI-RS resource),并且配置参数TRS-Info;
2)此外,还有其他一些配置要求。
对于周期的CSI-RS resource,目前都会配置对应的准共址(QCL,Quasi Co-Located)信息,其具体指向一个TCI-State。在CSI-RS resource set中, 目前对于不同的CSI-RS resource的QCL信息可以任意配置。这会带来性能的损失,例如不同的CSI-RS resource需要使用不同的接收beam来接收,则会导致不同CSI-RS resource传输所对应的信道的统计特性不同,影响定时和频率同步/跟踪的精度。
