具体实施方式
一、关于定位频率层(positioning frequency layer):
新空口(New Radio,NR)定位中,引入了PRS,用于终端进行定位测量。为了完成定位,终端需要测量多个小区的传输接收点(Transmission reception point,TRP)发送的PRS。通常为了保证高精度的定位,网络侧会配置较大的带宽的PRS(通常PRS带宽越大,定位精度越高)。
NR定位还定义了定位频率层概念,定位频率层是一组TRP下PRS的集合,这些PRS具有相同的子载波间隔、循环前缀(Cyclic Prefix,CP)类型、参考点A(pointA)、带宽、梳状大小(comb size)。一个定位频率层可以包含多个TRP,每个TRP中可以包含多个PRS资源集(resource set),每个PRS resource set中可以包含多个PRS resource。
二、测量间隔(Measurement Gap,MG):
NR定位中,终端在测量PRS时,需要使用measurement gap。在没有配置测量间隔时,终端不期望处理PRS。
目前,根据终端能力只支持同一时刻处理一个定位频率层的PRS。
当终端期望去测量激活(active)部分带宽(Band Width Part,BWP)外的PRS resource或者与active BWP基带参数(numerology)不同的PRS resource,终端可以向服务下一代基站(next generation NodeB,gNB)发送请求信令,请求配置测量间隔。服务gNB决定如何配置测量间隔,随后向UE下发measurement gap配置,UE可以使用配置的测量间隔测量PRS。而当服务gNB不配置测量间隔的话,终端只能在active下行链路(Down Link,DL)BWP内测量PRS。
另外,在现有协议中,PRS的配置由位置服务器通过长期演进定位协议(LTE Positioning Protocol,LPP)信令直接发送给终端,服务gNB并不知道具体配置信息,当终端需要使用测量间隔测量PRS时,需要向服务gNB请求 测量间隔。

下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的处理参考信号资源的方法、装置、设备及可读存储介质进行详细地说明。
参见图2,本申请实施例提供一种处理参考信号资源的方法,该方法的执行主体可以是终端,具体步骤包括:步骤201。
步骤201:根据协议约定或网络侧配置或终端选择,同时对一个或多个定位频率层的第一参考信号资源进行处理。
需要说明的是,第一参考信号用于下行定位,比如、PRS、同步信号块(Synchronization Signal and PBCH block,SSB)、信道状态信息参考信号(CSI Reference Signal,CSI-RS)或者跟踪参考信号(Tracking Refernece Signal,TRS)等。
对多个定位频率层(比如,两个定位频率层或者两个以上定位频率层)的第一参考信号资源进行处理,即:对每个TRP下,位于多个定位频率层的第一参考信号资源进行处理。这里,多个定位频率层可以包含相同的TRP列表。
可选的,终端还可以根据协议约定或网络侧配置或终端选择,对1个定 位频率层中位于的第一参考信号资源进行处理。
可以理解的是,同时是指同一时刻(或者同一个时间单元),比如,同一个时隙、同一个子帧、同一个符号等。
需要说明的是,处理包括:分别处理(或者称为非聚合处理)或聚合处理。
其中,分别处理:只是同时对频率不连续的第一参考信号进行测量,但不进行聚合处理,对各个不连续的第一参考信号分别计算,不增大有效带宽。
聚合处理:同时对频率不连续的第一参考信号进行测量,对不连续的第一参考信号进行聚合处理,增大有效带宽。
以基于时间的定位方法为例(DL-TDOA,Multi-RTT)。
分别处理:UE测量多个定位频率层,每个频率层得出1个时间测量值。可选的,对每个频率层的结果进行平均,最终得出平均后的结果,不增加有效带宽,不能有效提高测量精度。
聚合处理:UE聚合多个定位频率层的第一参考信号资源,增大了有效第一参考信号带宽,得出相应的1个精度更高的时间测量值。
聚合处理中,不连续的第一参考信号资源处理是强耦合。
在一些实施方式中,终端可以根据第一参考信号的配置信息,同时对一个或多个定位频率层的第一参考信号资源进行处理。
可选地,所述配置信息包括:定位频率层的信息,所述定位频率层包括:多个信道带宽部分;

相应地,在步骤201中,终端可以根据所述定位频率层组的信息,对所述定位频率层组中的多个定位频率层的第一参考信号资源进行聚合处理或非聚合处理。
可以理解的是,定位频率层组可以等效为定位频率层聚合组或聚合指示。可以理解为:当收到定位频率层组的配置,即对定位频率层组内的所有定位 频率层进行聚合处理。
在一些实施方式中,所述定位频率层组的信息包括聚合指示,所述聚合指示用于指示对所述定位频率层组中的多个定位频率层的第一参考信号资源进行聚合处理。也就是说,如果定位频率层组的信息没有包含聚合指示,则UE对该定位频率层组中的多个定位频率层不进行聚合处理。
在一些实施方式中,所述定位频率层组的信息包括:多个定位频率层的信息,至少部分定位频率层的信息包括:聚合指示,所述聚合指示用于指示对所述至少部分定位频率层的第一参考信号资源进行聚合处理。
在一些实施方式中,所述定位频率层组的信息包括:传输接收点TRP的信息,所述TRP的信息包括:聚合指示,所述聚合指示用于指示对所述TRP的至少部分定位频率层的第一参考信号资源进行聚合处理。
也就是说,可选地,聚合指示还可以在定位频率层组中的某些定位频率层中配置,用于指示UE对组中特定的定位频率层进行聚合处理。
可选地,UE可以选择定位频率层组中的2个或多个定位频率层聚合处理。或者,聚合指示还可以在定位频率层组中特定的TRP下配置,用于指示UE对该TRP下的全部、某些定位频率层的第一参考信号进行聚合处理。
在一些实施方式中,所述多个定位频率层的特性包括以下一项或多项:

也就是说,每个TRP同时发送处于不同的定位频率层的多个第一参考信号资源,UE进行聚合处理。频率层1中包含64个TRP,频率层2中包含与频率层1完全相同的TRP,即频率层2上的第一参考信号资源与频率层1的第一参考信号资源来自相同的TRP,但是频域位置不同。
进一步的,每个定位频率层中相同的TRP的TRP ID相同。其中,TRP ID包括以下一项或多项:DL第一参考信号ID、物理小区标识(Physical Cell ID,PCI)、NR小区全球标识符(NR Cell Global Identifier NCGI)。
进一步的,多个定位频率层相同的TRP,可以理解为同一个TRP发送处于不同的定位频率层的多个第一参考信号资源。进一步的,多个第一参考信号资源可以同时发送。
进一步的,同一TRP同时在不同的定位频率层发送的多个第一参考信号资源各自属于不同的第一参考信号资源集。即,同1个TRP在不同的定位频率层同时发送不同的第一参考信号资源集。

示例1:
本实施例给出了不同定位频率层,即使包含同1个TRP,但是TRP ID不同的方案。
网络指示多个定位频率层,多个定位频率层中包含相同的TRP,但是TRP ID不同。
某个定位频率层的某个TRP配置下,网络指示该TRP的TRP ID,并指示该TRP关联的另一个TRP ID(associated TRP ID),用于表示2个TRP ID对应同一个TRP。
UE在收到某个TRP有关联的‘associated TRP ID’,则认为2个定位频率层对应的是相同的TRP,或者这2个TRP ID实际对应同一个TRP的不同的定位频率层。
另外,其他定位频率层下TRP对应的一些参数,也可以复用‘associated TRP ID’对应的TRP下的参数,以节省开销。
进一步的,协议约定或网络指示:同一时刻,UE对不同定位频率层下,associated TRP ID相同的TRP发送的第一参考信号进行聚合处理。
示例2:
每个频率层中包含相同的TRP,但在每个频率层中,TRP ID不同。这种情况,网络侧配置同1个TRP中某个TRP ID为‘参考TRP ID(reference TRP ID)’(或关联TRP ID,associated TRP ID)。并把参考TRP ID配置在其他频率层中同一个TRP(但TRP ID不同)下的参数中,用于指示多个TRP ID对应的TRP相同。
另外,其他定位频率层下TRP对应的一些参数,也可以复用参考TRP ID对应的TRP下的参数,以节省开销。
UE得到指示后,对同一个TRP不同的定位频率层下的第一参考信号资源(或第一参考信号资源集)进行聚合。
