在NR系统中,探测参考信号(Sounding Reference Signal,SRS)可用于波束管理(beam management)、基于码本(codebook)的传输、基于非码本(non-codebook)的传输、天线切换(antenna switching)发送。终端可以通过高层信令获取多个SRS资源集合,每个SRS资源集合配置中包含其用途、周期特性等配置。
在Release-15/16中,在1个时隙内,SRS资源可占用最后6个符号,高层信令可配置SRS占用1/2/4个符号传输,并支持频域上的梳状结构comb-2,comb-4结构。在Release-17中,在Release-15/16的基础上进行了增强,在1个时隙内,SRS资源的符号起始位置可以在一个时隙内的任意符号上。并且还支持了comb-8的结构。
在现有的NR协议中,只支持SRS的端口数为1、2、4。为了进一步提升上行传输的性能,需要引入支持更多端口数的SRS,例如SRS端口数为6、8。由于不同的SRS端口之间需要尽可能地保证正交性,现有的SRS端口映射方式不能完全适用于SRS端口数为6和8的情况。
