为了更好地对本申请各实施例进行介绍,首先介绍一下内容:
(1)网络通过无线资源控制(Radio Resource Control,RRC)配置;
RRC参数SRS resource set中包含资源类型resourceType域,若该域被配置成非周期,非周期域中包含aperiodicSRS-ResourceTrigger和aperiodicSRS-ResourceTriggerList,分别在触发候选状态(1,2,3)中选择一个或选择两个作为该set的任务状态trigger state。
(2)网络通过下行控制信息(Downlink Control Information,DCI)激活;
SRS request对于没有在该小区被配置成上行补充(upplimentary uplink),用2bits用于指示trigger state;
SRS request对于在该小区被配置成SUL,用1bit用于non-SUL/SUL指示,用2bits用于指示trigger state;
具体指示方式如下表1所示:
表1 SRS request

其中,00代表不激活;
01代表激活trigger state=1或trigger state list中包含1;
10代表激活trigger state=2或trigger state list中包含2;
11代表激活trigger state=3或trigger state list中包含3。
(3)SRS激活时间相关要求;
如下表2所示,对于usage=codebook/antennaSwitching,用于激活的PDCCH的最后一个符号到该被激活的SRS resource之间的最小时间间隔是N2;
对于usage=noncodebook/BM,用于激活的PDCCH的最后一个符号到该被激活的SRS resource之间的最小时间间隔是N2+14;
N2的单位是symbol,且是按照PDCCH以及激活的SRS resource中最小的SCS计算的。

slot上传输;
当在激活的cell中的SRS被配置了ca-SlotOffset,SRS资源在

slot上传输;
其他情况下:k是SRS set中配置的slotoffset,支持0-32slot;与PDCCH和触发的SRS的SCS有关。
(3)推迟发送;
对于非周期的SRS触发,如果指定的时隙位置上无法发送SRS,UE会在从指定时隙位置开始后找第一个可以用于发送SRS的时隙用于发送所述SRS,其中所述指定时隙位置是指根据用于触发的PDCCH以及所触发的SRS上配置的时隙偏移确定的。
可以通过触发非周期SRS的DCI发送的时隙以及所述DCI中配置有效时隙指示+非周期SRS中配置的时隙偏移来确定所述SRS的时域位置,也可以通过触发非周期SRS的DCI发送的时隙以及非周期SRS中配置的时隙偏移重新定义为有效时隙后来确定所述SRS的时域位置等方法。
(4)同发能力;
目前SRS有多种usage用法、惯例,包含beammanagement,antenna switching,codebook,non-codebook。
对于SRS for CB/NCB/BM+SRS for CB/NCB/BM在不同载波上同时发送,需要网络支持CA的能力,也就是支持CA的能力后,也就支持上述SRS同时发送的能力
对于SRS for AS+SRS for CB/NCB/BM/AS,需要UE上报是否支持相应的同发能力。
