技术领域
本申请属于通信技术领域,具体涉及一种时间误差组指示方法、装置、终端及网络侧设备。
背景技术
从信号传输的角度来看,从在基带生成数字信号的时间到从Tx天线发送射频(Radio Frequency,RF)信号的时间会有时间延迟。为了支持定位,终端(User Equipment,UE)或发送和接收点(transmission and receiving points,TRP)可以对下行定位参考信号(Downlink Positioning Reference Signal,DL PRS)或上行探测参考信号(Uplink Sounding Reference Signal,UL SRS)的传输实施Tx时间延迟(Tx time delay)的内部校准/补偿。校准后剩余的Tx时间延迟或未校准的Tx时间延迟定义为Tx时间误差(Tx timing error)。从信号接收的角度来看,从Rx天线接收RF信号到基带处理会有时间延迟。为了支持定位,UE或TRP可以在进行测量上报前,对DL PRS或UL SRS的测量结果执行Rx时间延迟(Rx time delay)的内部校准/补偿。校准后剩余的Rx时间延迟或未校准的Rx时间延迟定义为Rx时间误差(Rx timing error)。

可选的,所述TRP的多个下行定位参考信号资源集与TRP的多个天线端口具有关联关系,包括以下之一:
不同的下行定位参考信号资源集关联不同组的TRP天线端口;例如,2个PRS资源集,8个TRP端口。每个资源集对应2个TRP端口组,一个TRP端口组包含4个天线端口。
至少一个下行定位参考信号资源集关联1组的TRP天线端口;例如2个PRS资源集,8个TRP端口。1个PRS资源集关联全部TRP端口,另一个PRS资源集也关联全部TRP端口。

不同的重复的下行定位参考信号资源关联不同的TRP的天线端口;比如1个PRS资源关联2个端口。同一个PRS资源标识对应2个重复的PRS资源,各对应一个端口。

终端接收网络侧设备发送的第一请求消息,所述第一请求消息用于请求终端指示所述第一信息。
可选的,对于定位精度要求不高的场景,网络侧设备可以要求终端不提供第一信息。因此,可以不使能‘第一请求消息’。
可选的,本申请中终端指示第一信息时,描述的“网络侧设备指示”, 都可以包含在该第一请求消息中。

可选的,终端指示第一关联关系,即终端指示上行定位参考信号与第一时间误差组TEG的关联关系,包括以下方式中的至少一项:
通过上行定位参考信号的序列,指示第一关联关系。
可选的,上行定位参考信号与第一TEG的关联关系通过上行定位参考信号的序列表示。例如,对于同一个SRS resource,不同的周期(或者SRS instance)之间,Tx TEG发生变化,同一个SRS resource的不同周期上的序列会不同。可以理解为,用于定位的SRS目前只支持1个端口,关联不同的TEG的SRS可以被看作是把SRS扩展至多个端口,SRS关联每个端口等效为SRS关联每个Tx TEG。
可选的,所述上行定位参考信号的序列是根据所述上行定位参考信号关联的第一TEG所对应的循环移位cyclic shift生成的,其中,不同的第一TEG对应不同的cyclic shift。
其中,不同的cyclic shift区别不同的第一TEG与Tx TEG的数目有关。
一种实施方式中,以上行定位参考信号为SRS为例,网络指示或协议约定一组cyclic shift集合,关联不同TEG的SRS对应各自的cyclic shift值,生成SRS序列。TEG0关联SRS时,UE使用TEG0对应的cyclic shift生成序列并发送;TEG1关联SRS时,UE使用TEG1对应的cyclic shift生成序列并发送。
可选的,通过上行定位参考信号的映射方式,指示第一关联关系。
可选的,上行定位参考信号与第一TEG的关联关系通过上行定位参考信号的映射方式表示。例如,对于同一个SRS resource,不同的周期之间,Tx TEG发生变化,同一个SRS resource的不同周期上的映射图样会不同。
可选的,所述上行定位参考信号的映射方式是根据所述上行定位参考信号关联的第一TEG所对应的时频位置确定的,其中,通过频分复用(Frequency Division Multiplexing,FDM)的方式区分不同的第一TEG。
其中,FDM的方式区别不同的TEG与Tx TEG的数目有关。
一种可选的实施方式中,关联不同TEG的SRS可以映射到同一个symbol上不同的资源单元(Resource element,RE)上,通过FDM区分。TEG1关联SRS时,UE使用TEG1对应的时频位置发送SRS。
可选的,当UE支持的第一TEG数目很多时,可以结合上行定位参考信号的序列以及的映射方式联合区分多个第一TEG。
可选的,终端通过上行定位参考信号的序列或上行定位参考信号的映射方式,指示第一关联关系之前,还包括:
终端接收网络侧设备发送的第一指示信令,所述第一指示信令用于指示终端开启或使能通过上行定位参考信号的序列和/或映射方式指示第一关联关系的功能;
终端开启通过上行定位参考信号的序列和/或映射方式指示第一关联关系的功能。
可选的,网络侧设备可以指示是否开启“用序列和/或映射方式表示SRS 与TEG关联关系”功能,比如通过开关指示。
一种实施方式,当服务gNB收到位置服务器的请求,比如要求(实时)获得SRS与Tx TEG的关联关系。服务gNB即可指示UE开关开启。UE根据指示通过序列和/或映射方式指示SRS与Tx TEG的关联关系。比如,在UE只支持/关联1个Tx TEG的场景,或者对定位精度要求不高的场景,开关设置为“关”或者缺省指示。
可选的,所述上行定位参考信号序列和/或上行定位参考信号的映射方式由协议约定、网络指示和终端选择中的至少一种方式获得。即终端使用“序列方式”,还是“映射方式”,还是“序列+映射”方式表示上行定位参考信号与第一TEG的关系,可以由协议约定、网络指示和/或终端选择。
可选的,上行定位参考信号与第一TEG的关联关系也可以是显示指示的,包括至少以下方式之一:
通过事件触发方式,指示第一关联关系;

终端至少发送一次第二指示信令,所述第二指示信令用于指示所述第一关联关系。
可以理解的是,事件触发指示前,UE至少指示一次上行定位参考信号与第一TEG的关联关系。

下面通过一个具体的例子,说明通过事件触发方式,指示第一关联关系。图3为本申请实施例提供的事件触发指示方式的示意图。
方式一:
某个SRS instance X(如图3中的SRS instance 3),SRS与Tx TEG的关联关系相比于SRS instance A发生了变化(事件发生,事件信息可以由协议约定或网络指示),则触发UE指示SRS instance X中SRS与Tx TEG的关联关系或关联关系的变化。其中,SRS instanceA可以是以下之一:
第一个SRS instance;

这里,该信令指示生效的时间为:该信令之前最近的1个SRS instance至下次信令前2个SRS instance(如SRS instance 3与SRS instance 4)。生效时间内的多个SRS instance中,SRS与TEG的关系不变。
可选的,UE指示SRS instance X的信令不晚于SRS instance X后的时间T,其中T可以由协议约定或网络指示。
可选的,事件触发指示前,UE至少上报一次SRS与Tx TEG的关联关系,如上报SRS发送初始阶段(如第一个SRS instance)关联关系,或者某个/些SRS instance的关联关系(由网络指示/协议约定/UE选择)。
方式二:
UE预期某个SRS instance的SRS与Tx TEG的关联关系要发生变化,比如UE完成了panel切换,(预期之后的SRS与Tx TEG的关系要发生变化),触发UE指示关系变化。此方式下,该信令指示该信令之后到下一次信令之前这段时间的SRS与TEG的关联关系。如图3中第一个指示信令指示SRS instance 3与SRS instance 4中的SRS与TEG的关联关系。

其中,所述周期T和/或周期偏移由协议约定、网络指示和终端选择中的至少一种方式获得。
其中,周期性指示一般为终端根据网络配置周期和/或周期偏移发送指 示;也可以是终端先接收网络预配置周期和/或偏移,再接收网络的激活指示(如MAC CE激活信令),激活终端发送指示。
可选的,所述周期T与上行定位参考信号的发送周期有关。例如,周期T为SRS周期的Q倍,Q为正整数。
可选的,所述周期T与基站gNB上报上行定位测量结果的周期相关。例如,周期T为gNB上报SRS测量结果周期的Q倍,Q为正整数。

UE不期望1个measurement instance的PRS resource关联多个Tx TEG.
UE不期望PRS repetition时,关联多个Tx TEG.
1个measurement instance包含多个PRS resource set instance。一般来说,1个measurement instance确定一次测量结果(比如确定一次RSTD结果时)。确定结果时,UE会对多个PRS resource set instance(可以认为是多个PRS周期)的测量结果进行联合处理,比如做平滑/平均,得出一个较好的结果。但 是,如果确定一次测量结果时,若每个PRSresource set instance的测量结果关联不同的Rx TEG,那么最后联合计算的结果会出现误差。因此,我们这里提出了UE行为,即UE在确定测量结果时联合处理的多个PRS resource set instance要关联相同的Rx TEG。同理,也要关联相同的Tx TEG.。
可选的,终端发送上行定位参考信号时,终端不被允许在SRS repetition时,关联多个Tx TEG。

上述各实施例主要给出了上行定位参考信号与第一TEG的关联关系,下行定位测量结果与第二TEG的关联关系,下行定位参考信号与第三TEG的关联关系,上行定位测量结果与第四TEG的关联关系,但并没有解释网络侧设备通过上述关系如何消除TEG的误差。因此,本申请还给出了几个利用上述关系消除TEG误差的具体实施方式。
实施方式一
DL-TDOA定位中,UE上报PRS measurment与Rx TEG的关联关系至位置服务器(如LMF)。假设UE有2个Rx TEG(Rx TEG0,Rx TEG1)。步骤如下:
(1)DL-TDOA定位中,多个TRP发送PRS,UE来接收。要计算不同TRP之间的RSTD(参考信号时间差)值,就要以某个TRP为参考,其他TRP与参考TRP的PRS的测量结果做差。其中,某个TRP的测量结果可以理解为UE对某个TRP下的PRS resource测量后的结果。对于参考TRP来说,若UE测量参考TRP的PRS resource与Rx TEG0有关,而UE测量某个TRP A的PRS resource与Rx TEG1有关,那么在计算TRP A相对于参考TRP的RSTD时,则会引入Rx TEG0与Rx TEG1差的误差。
(2)UE上报TRP1中某个PRS resource下,Rx TEG0的测量结果及Rx TEG1的测量结果。那么,LMF对Rx TEG0与Rx TEG1的测量结果做差,即获得了Rx TEG0与Rx TEG1的差。
(3)获得的Rx TEG0与Rx TEG1的差,就可以补偿在(1)中的RSTD结果中,消除了这个误差。
实施方式二
UL-TDOA定位中,UE上报SRS与Tx TEG的关联关系至位置服务器(如LMF)。假设UE有2个Tx TEG(Tx TEG0,Tx TEG1)。步骤如下:
(1)UL-TDOA定位中,UE发送SRS,多个TRP来接收。原理类似与DL-TDOA,要计算不同TRP之间的RTOA(接收到达时间)的差,就 要以某个TRP为参考,其他TRP与参考TRP的SRS测量结果做差。其中,某个TRP的测量结果可以理解为对UE的某个SRS resource的测量之后的结果。对于参考TRP来说,若参考TRP的测量的SRS resource与UE Tx TEG0有关,而某个TRP A的测量的SRS resource的测量结果与UE Tx TEG1有关,那么在计算TRP A相对于参考TRP的RTOA差时,则会引入UE Tx TEG0与UE Tx TEG1差的误差。
(2)UE可以通过多种方式指示SRS与UE Tx TEG的关联关系。某个gNB可以测量获得2个SRS resource的RTOA值,且每个SRS resource关联2个Tx TEG,那么该gNB即可计算获得UE Tx TEG0与UETx TEG1的差,并上报至位置服务器。
(3)那么,获得UE Tx TEG0与UETx TEG1的差后,位置服务器就可以补偿在(1)中的RTOA差中引入的UE Tx TEG0与UE Tx TEG1差的误差。
