技术领域
本申请涉及无线通信技术领域，尤其涉及一种通信方法及装置。
背景技术
在定位场景中，网络设备可以下发定位参考信号(positioning reference signal，PRS)配置信息，终端设备可以根据PRS配置信息，确定每个PRS来自于哪个传输点。然后测量多个PRS的到达时间(差)或到达角度，确定终端设备与各传输点之间的距离(差)或到达角度，并根据每个传输点的坐标，确定该终端设备的位置。因此PRS配置信息中携带信息可以计算出终端设备的位置，PRS配置信息中不包括额外的指示信息。
但是在其他信号与PRS碰撞处理，上行定位信号开环功控处理及空间关系配置处理等不同的情况中，还需要确定PRS来自服务小区或非服务小区。而现有技术中无法判断PRS来自服务小区或非服务小区，导致无法准确处理其他信号和PRS的碰撞，以及无法准确配置上行定位参考信号的功率和波束，导致定位精度低，定位性能差。

本申请中的“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本申请中所涉及的多个，是指两个或两个以上。
另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
本申请实施例的技术方案可以应用于各种通信系统(也称移动通信系统或无线通信系统)。通信系统通常包括但不限于4G网络、LTE系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统、5G通信系统或NR以及未来的其他通信系统如6G等。
如图1所示为一种可能的通信系统架构，包括终端设备(UE)，接入网设备(如图1中的下一代(next generation，ng)-eNB和gNB)，核心网设备(如图1中的AMF和LMF)。可选的，通信系统架构中还包括增强移动服务定位中心(enhanced serving mobile location centre，E-SMLC)和存储有服务定位协议(service location protocol，SLP)的实体。可选的，ng-eNB可以包括一个或多个传输点TP，gNB可以包括一个或多个传输点TP。
其中ng-eNB与UE之间的LTE-Uu接口，gNB与UE之间的NR-Uu接口，ng-eNB与AMF之间的NG-C接口，gNB与AMF之间的NG-C接口，LMF与AMF之间的NLs接口，ng-eNB与gNB之间的Xn接口的含义可参见3GPP标准协议中定义的含义，本申请对于上述接口的含义不做限制。需要说明的是，图1中的各个网络功能之间的接口名称仅仅是一个示例，在具体实现中，该系统架构的接口名称还可能为其他名称，本申请对此不作限定。
参见图2对定位过程进行说明。LMF通过高层信令向传输点(一般为多个传输点)请 求PRS配置信息，传输点通过高层信令向LMF提供PRS配置信息。该LMF通过LTE定位协议(LTE positioning protocol，LPP)信令向UE发送各传输点的PRS配置信息。各传输点向UE发送PRS。UE基于各传输点的PRS配置信息，对接收到的每个PRS进行测量。UE将测量结果上报给LMF，LMF根据UE上报的测量结果估算UE的位置。
以DL-TDOA为例，结合图3，对LMF估算UE的位置的过程进行说明。图3中包括3个传输点，分别为传输点1、传输点2和传输点3。已知传输点1的坐标为(x 1，y 1)，传输点2的坐标为(x 2，y 2)，传输点3的坐标为(x 3，y 3)。假设待定位的UE的坐标为(x UE，y UE)，其中x UE和y UE为未知数。以传输点1作为参考传输点，UE测量传输点2的PRS与传输点1的PRS之间的到达时间差Δt 21，以及传输点3的PRS与传输点1的PRS之间的到达时间差Δt 31。根据双曲线的定义(即与两个固定的点的距离差为常数)，UE位于以传输点1和传输点2为焦点的双曲线上，得到方程(1)，且UE位于以传输点1和传输点3为焦点的双曲线上，得到方程(2)。
Figure PCTCN2022083790-appb-000001
Figure PCTCN2022083790-appb-000002
其中c为光速，因此只存在待求解的两个未知数x UE和y UE，联合方程(1)和(2)即可计算出UE的位置坐标。
可见，UE或LMF知道每个PRS来自哪个传输点，并且知道每个传输点的坐标，就可以算出UE的位置，因此PRS配置信息中不必须包括额外的指示信息。但是在下述情况下还需要考虑PRS来自服务小区或非服务小区。
第一种可能的情况，同步信号和广播物理信道(physical broadcast channel，PBCH)块(synchronization signal and PBCH block，SSB)与PRS的碰撞处理。
如果基站确定一个时频资源上存在待发送的SSB和PRS，基站在该时频资源上发送SSB，而不发送PRS。
UE在接收PRS之前，判断PRS资源所在的正交频分复用(orthogonal frequency division multiplexing，OFDM)符号上是否存在SSB(或SSB的时频资源)。如果这些OFDM上存在与PRS同一服务小区的SSB，UE不去接收该服务小区的PRS。或者如果这些OFDM上存在与PRS同一非服务小区的SSB，UE不去接收该非服务小区的PRS。这样可以避免UE产生不必要的功耗，使得UE更加省电。
例如，若传输点确定同一服务小区的SSB和PRS发生碰撞，该传输点不发送PRS。但是对于UE来说，如果UE不能正确判断SSB和PRS发生碰撞，UE仍然会检测PRS，但传输点实际上并没有发送PRS，UE就会错误检测到PRS(如到达时间(time of arrival，TOA)测量错误)，影响下行定位技术的定位精度和定位性能。
又如，实际上SSB和PRS没有发生碰撞，传输点会下发PRS。但是对于UE来说，如果UE错误认为SSB和PRS发生碰撞，UE就不会检测PRS，造成PRS的漏检，同样会影响下行定位技术的定位精度和定位性能。
第二种可能的情况，探测参考信号(sounding reference signal，SRS)的开环功控处理及空间关系配置处理。
目前支持将PRS配置为上行定位SRS的路损参考信号，实现功率配置。具体的，可以给SRS配置服务小区的PRS，也可以配置非服务小区的PRS。
并且目标支持将PRS作为SRS的空间关系参考信号，实现波束配置。具体的，可以给SRS配置服务小区的PRS，也可以配置非服务小区的PRS。
例如，UE想要基于服务小区的PRS发送SRS，但是由于UE配置出错，UE可能会基于非服务小区的PRS发送SRS，导致功率配置出错，或者波束配置出错，影响上行定位技术的定位精度和定位性能。
综上，相关技术中无法判断PRS来自服务小区或非服务小区，导致无法准确处理SSB和PRS的碰撞，以及无法准确配置上行定位SRS的功率和波束，存在定位精度低，定位性能差的问题，因此亟需一种技术方案区分PRS来自服务小区或非服务小区。
基于此，本申请实施例提供一种通信方法。在该方法中，终端设备可以根据定位参考信号配置信息包括的物理小区标识和/或小区全球标识，在第一条件得到满足时，确定该定位参考信号配置信息对应的定位参考信号来自服务小区，在第二条件得到满足时，确定该定位参考信号配置信息对应的定位参考信号来自非服务小区。因此终端设备可以确定定位参考信号来自服务小区或非服务小区，进而可以准确处理定位参考信号与其他信号的碰撞，以及准确配置上行定位信号的功率和波束，提高定位精度和性能。
本申请实施例提高的通信方法可以应用于图1或图3所示的通信系统中。图4为本申请实施例提供的一种可能的通信过程，该过程包括：
S401：终端设备接收定位参考信号配置信息。

S402：在定位参考信号配置信息包含物理小区标识和/或小区全球标识的情况下，若第一条件得到满足，终端设备确定定位参考信号配置信息对应的定位参考信号来自服务小区。
一般的，终端设备接入服务小区后，终端设备可以获取到该服务小区的信息。例如服务小区的信息包括以下一种或多种：服务小区的物理小区标识、服务小区的全球小区标识、服务小区对应的频带等。其中服务小区对应的频带指：服务小区在频谱中的位置以及占用的带宽。可选的，若终端设备接入服务小区后，未获取到该服务小区的信息，该服务小区或LMF可以向终端设备发送该服务小区的信息。

示例性的，当定位参考信号配置信息还包括定位参考信号所在的频段，且该定位参考信号所在的频段通过绝对射频信道号(absolute ratio frequency channel number，ARFCN)指示时，若定位参考信号配置信息包括的ARFCN和服务小区的ARFCN相同，终端设备可以确定定位参考信号所在的频带与服务小区对应的频带相同。
以上述定位参考信号配置信息包括nr-PhysCellID-r16、nr-CellGlobalID-r16、nr-ARFCN-r16中的一个或多个为例，如果nr-PhysCellID-r16和nr-CellGlobalID-r16两个参数中至少一个参数被提供，并且与dl-PRS-ID-r16关联的nr-PhysCellID-r16、nr-CellGlobalID-r16、nr-ARFCN-r16中的一个或多个参数，分别与服务小区的物理小区标识、全球小区标识、ARFCN中对应的一个或多个参数相同，终端设备可以确定定位参考信号来自于服务小区，此时第一条件得到满足。
示例的，当定位参考信号配置信息中提供包括nr-PhysCellID-r16时，若该 nr-PhysCellID-r16与服务小区的物理小区标识(PCI)相同，且定位参考信号所在的频带与该服务小区对应的频带相同，终端设备可以确定定位参考信号来自服务小区。此时若定位参考信号配置信息不包括nr-ARFCN-r16，终端设备可以根据定位参考信号配置信息中的其他字段(例如pointA字段)，确定定位参考信号所在的频段。
当定位参考信号配置信息包括nr-CellGlobalID-r16时，若该nr-CellGlobalID-r16与服务小区的小区全球标识(CGI)相同，终端设备可以确定定位参考信号来自服务小区。
当定位参考信号配置信息包括nr-PhysCellID-r16和nr-CellGlobalID-r16时，若该nr-PhysCellID-r16和服务小区的物理小区标识相同，且该nr-CellGlobalID-r16和该服务小区的小区全球标识相同，终端设备可以确定定位参考信号来自服务小区。

当定位参考信号配置信息包括nr-CellGlobalID-r16和nr-ARFCN-r16时，若该nr-CellGlobalID-r16和服务小区的小区全球标识相同，且该nr-ARFCN-r16和该服务小区的ARFCN相同，终端设备可以确定定位参考信号来自服务小区。
当定位参考信号配置信息包括nr-PhysCellID-r16、nr-CellGlobalID-r16和nr-ARFCN-r16时，若该nr-PhysCellID-r16和服务小区的物理小区标识相同，该nr-CellGlobalID-r16和该服务小区的小区全球标识相同，且该nr-ARFCN-r16和该服务小区的ARFCN相同，终端设备可以确定定位参考信号来自服务小区。
一种可能的情况下，定位参考信号配置对应的定位参考信号不关联任何小区，即定位参考信号既不属于服务小区也不属于非服务小区。例如，在第三条件得到满足时，终端设备还可以确定该定位参考信号配置信息对应的定位参考信号不关联任何小区。该第三条件包括：定位参考信号配置信息不包括物理小区标识和小区全球标识。
可选的，在定位参考信号配置信息包含物理小区标识和/或小区全球标识的情况下，若第二条件得到满足时，终端设备可以确定该定位参考信号配置信息对应的定位参考信号来自非服务小区。
第二条件为：不满足上述第一条件，且不满足上述第三条件。无论终端设备是否可以获取到非服务小区的信息，若不满足上述第一条件，且不满足上述第三条件，终端设备可以确定上述定位参考信号配置信息包括的物理小区标识和/或小区全球标识，满足第二条件。也就是说，在定位参考信号配置信息包含所述物理小区标识和/或小区全球标识的情况下，若第一条件不满足，终端设备确定定位参考信号配置信息对应的定位参考信号来自非服务小区。
一种可能的方式中，终端设备可以根据定位参考信号配置信息包括的物理小区标识和/或小区全球标识，若确定该定位参考信号配置信息包括的物理小区标识与服务小区的物理小区标识不同，和/或定位参考信号配置信息包括的小区全球标识与服务小区的小区全球标识不同，确定定位参考信号来自非服务小区。
若所述终端设备获取到非服务小区的信息，所述第二条件具体可以包括：定位参考信号配置信息包括的物理小区标识与非服务小区的物理小区标识相同，且定位参考信号所在 的频带与非服务小区对应的频带相同；和/或定位参考信号配置信息包括的小区全球标识与非服务小区的小区全球标识相同。
可以理解的是，终端设备在接收一个定位参考信号之前，接收该定位参考信号的定位参考信号配置信息。也就是说，在S401和S402中，终端设备还未接收到定位参考信号配置信息对应的定位参考信号。这里所涉及的“定位参考信号”可以理解为定位参考信号资源或定位参考信号序列等。
通过本申请实施例提供的通信方法，终端设备可以根据定位参考信号配置信息包括的物理小区标识和/或小区全球标识，确定该定位参考信号配置信息对应的定位参考信号来自服务小区或非服务小区，进而可以准确处理定位参考信号与其他信号的碰撞，以及准确配置上行定位信号的功率和波束，提高定位精度和定位性能。
本申请实施例还可以提供另一种技术方案来确定定位参考信号来自服务小区或非服务小区。例如，终端设备接收来自网络设备的定位参考信号配置信息，所述定位参考信号配置信息用于指示所述定位参考信号配置信息对应的定位参考信号来自服务小区，或者用于指示所述定位参考信号配置对应的定位参考信号来自非服务小区。
该网络设备可以为传输点，基站或LMF。若该网络设备为LMF，网络设备可以确定该终端的服务小区，从而在定位参考信号配置信息中进行相应的指示。例如网络设备可以与该终端设备交互，确定该终端设备的服务小区的相关信息，在定位参考信号配置信息对应的定位参考信号来自该终端设备的服务小区时，在该定位参考信号配置信息中进行相应的指示。又如，网络设备可以与小区交互，确定将该小区作为服务小区的终端设备的信息(包括该终端设备的信息)，在该小区对应的定位参考信号配置信息(即该小区将要发送的定位参考信号对应的定位参考信号配置信息)发送给该终端设备时，在该定位参考信号配置信息中进行相应的指示。
可选的，所述定位参考信号配置信息中包括第一指示信息，所述第一指示信息用于所述定位参考信号配置信息对应的定位参考信号来自服务小区，或者用于指示所述定位参考信号配置对应的定位参考信号来自非服务小区。
在该方法中，终端设备可以根据定位参考信号配置信息的指示，直接确定该定位参考信号配置信息对应的定位参考信号来自服务小区或非服务小区，进而可以准确处理定位参考信号与其他信号的碰撞，以及准确配置上行定位信号的功率和波束，提高定位精度和定位性能。
根据对相关技术的描述，本申请实施例还可以提供一种技术方案来区分PRS与其他信号是否来自同一个服务小区或同一个非服务小区，来进一步提高定位精度和定位性能。

当定位参考信号配置信息包括nr-CellGlobalID-r16，第一信号配置信息包括小区全球标识时，若该nr-CellGlobalID-r16与该第一信号的小区全球标识(CGI)相同，终端设备可以确定该定位参考信号和该第一信号来自同一个小区。若同时该定位参考信号来自服务小区，则第四条件得到满足，该定位参考信号与该第一信号来自同一个服务小区。若同时该定位参考信号来自非服务小区，则第五条件得到满足，该定位参考信号与该第一信号来自同一个非服务小区。

当定位参考信号配置信息包括nr-PhysCellID-r16和nr-ARFCN-r16，第一信号配置信息包括物理小区标识和ARFCN时，若该nr-PhysCellID-r16和该第一信号的物理小区标识相同，且该nr-ARFCN-r16和该第一信号的ARFCN相同，终端设备可以确定该定位参考信号和该第一信号来自同一个小区。若同时该定位参考信号来自服务小区，则第四条件得到满足，该定位参考信号与该第一信号来自同一个服务小区。若同时该定位参考信号来自非服务小区，则第五条件得到满足，该定位参考信号与该第一信号来自同一个非服务小区。
当定位参考信号配置信息包括nr-CellGlobalID-r16和nr-ARFCN-r16，第一信号配置信息包括小区全球标识和ARFCN时，若该nr-CellGlobalID-r16和该第一信号的小区全球标识相同，且该nr-ARFCN-r16和该第一信号的ARFCN相同，终端设备可以确定该定位参考信号和该第一信号来自同一个小区。若同时该定位参考信号来自服务小区，则第四条件得到满足，该定位参考信号与该第一信号来自同一个服务小区。若同时该定位参考信号来自非服务小区，则第五条件得到满足，该定位参考信号与该第一信号来自同一个非服务小区。
当定位参考信号配置信息包括nr-PhysCellID-r16、nr-CellGlobalID-r16和nr-ARFCN-r16，第一信号配置信息包括物理小区标识、小区全球标识和ARFCN时，若该nr-PhysCellID-r16和该第一信号的物理小区标识相同，该nr-CellGlobalID-r16和该第一信号的小区全球标识相同，且该nr-ARFCN-r16和该第一信号的ARFCN相同，终端设备可以确定该定位参考信号和该第一信号来自同一个小区。若同时该定位参考信号来自服务小区，则第四条件得到满足，该定位参考信号与该第一信号来自同一个服务小区。若同时该定位参考信号来自非服务小区，则第五条件得到满足，该定位参考信号与该第一信号来自同一个非服务小区。
除上述情况外，定位参考信号与第一信号来自不同的小区，即来自不同的服务小区或不同的非服务小区。
可选的，若定位参考信号与第一信号来自相同的服务小区或相同的非服务小区，终端 设备可以不接收定位参考信号，不接收的该定位参考信号不参与定位测量。
通过本申请实施例提供的通信方法，终端设备可以确定定位参考信号与第一信号来自同一服务小区或者同一个非服务小区，进一步准确处理定位参考信号与其他信号的碰撞，从而进一步提高定位精度和定位性能。
在上述图4和图5所示的通信过程的基础上，结合图6对定位技术进行说明，包括如下步骤：
S601：LMF与终端设备交互定位能力。
上述定位能力包括PRS的处理能力。所述PRS的处理能力表示终端设备在一段时间内处理PRS的数量。
S602：LMF或传输点将每个传输点的PRS配置信息发送给终端设备。
其中，每个传输点为参与定位的传输点。
S603：参与定位的传输点向终端设备发送PRS。
S604：终端设备在接收到PRS配置信息后，确定PRS配置信息对应的PRS来自服务小区或非服务小区，以及确定是否存在SSB与PRS来自同一个服务小区或同一个非服务小区。
S604的实现过程可以参见上述图4和图5。
若存在SSB与PRS来自同一服务小区或同一个非服务小区，终端设备不接收该PRS，也即终端设备不在该PRS的资源上接收PRS，或者说终端设备跳过该PRS资源。
S605：终端设备对接收到的PRS进行测量。
S606：终端设备向LMF上报测量结果。
S607：LMF根据终端设备上报的测量接收估算终端设备的位置。
可选的，终端设备对接收到的PRS进行测量，可以估计自身所在的位置。
通过上述各实施例可以看出，终端设备可以准确判断出定位参考信号来自服务小区或非服务小区，以及定位参考信号与第一信号来自同一个服务小区或同一个非服务小区。
这样对于和第一信号来自同一个服务小区或同一个非服务小区的定位参考信号不进行检测，避免来自同一个服务小区或同一个非服务小区的定位参考信号和第一信号之间发生碰撞，并且可以准确接收与第一信号来自不同服务小区和/或不同非服务小区的其他定位参考信号既能够避免错误检测定位参考信号，可以避免漏检定位参考信号，从而保证下行定位技术的定位精度和定位性能。
