为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
在第16版本(Release 16，R16)和第17版本(Release 17，R17)中引入的定位架构主要是由终端(UE)、多个基站(gNB)、接入和移动性管理功能(Access and Mobility Management Function，AMF)实体和位置管理功能(Location Management Function，LMF)实体所组成。第一步，UE和/或gNB根据已知的配置式样发送探测参考信号(Sounding Reference Signal，SRS)和/或定位参考信号(positioning reference signals，PRS)。之后，gNB和/或UE再根据已知的配置式样对SRS和/或PRS进行测量，获取到离开角、到达角、距离、距离差等与定位相关的测量量。最后，这些测量量汇总到终端或者LMF执行定位，获取最终定位结果。
在5G定位系统中，不同终端/gNB发送的参考信号都应保持正交性，这样的话，能够保证系统中各方测量的信号固定来自一个点这个点所在位置，这种保证对于定位估计是基础性的。此外，正交性可以是在时/频/码至少之一域确保即可。
具体例如，可以基于多往返传输时间(multi Round Trip Time，multi-RTT)的定位方法来说明SRS和PRS的配置和对于它们的测量，如图2所示。在图2中第3a步，gNB为终端(UE)配置上行SRS的资源，继而在第5a步网络激活终端(UE)进行SRS的发射工作。在第6步，LMF通过NR定位协议a(New Radio Positioning Protocol a，NRPPa)测量请求(measurement Request)告知临近各gNB该终端(UE)的SRS资源配置，并要求各gNB对终端(UE)发送的SRS进行测量，并最终在第11步，各gNB将它们采集到的测量结果上报给LMF实体。此外，对于下行测量方向，在第7步和第8 步，网络先是将各gNB的独有的下行PRS配置信息发送给终端(UE)，继而激活终端(UE)执行下行测量，最终在第10步，终端(UE)将测量结果通过长期演进定位协议(Evolution Positioning Protocol，LPP)提供位置信息的消息(ProvideLocationInformation msg)发送至LMF实体。
具体参考信号(Reference Signal，RS)配置以下行(downlink，DL)PRS为例。NR DL PRS的配置信息由LMF通过LPP协议信令提供给UE。DL PRS的参数配置是采用了四层信令结构，从顶层到底层表示为：
定位频率层(Positioning Frequency Layer，PFL)；
发送接收点(Transmission Reception Point，TRP)；
DL PRS资源集(PRS resource set)；
DL PRS资源(PRS resource)。
在每个定位频率层(positioning frequency layer)里面，UE所配置的是多个TRP发送在同样频率点的DL PRS信号。而每个TRP里面可以配置一个或者两个DL PRS资源集，它们配置了这个TRP在某个频率点上发送的所有的DL PRS资源。而每个DL PRS资源集里面可以配置多个DL PRS资源，每个DL PRS资源可以代表一个TRP的发送波束而不同的DL PRS资源可以代表这个TRP的不同发送波束。
根据R16的规范，最多可以为一个终端(UE)提供4个定位频率层(PFL)的DL PRS配置。每一个定位频率层(PFL)的参数结构中提供了以下PRS信号的配置参数：
PRS信号的子载波间隔；
PRS信号的循环前缀(cyclic prefix，CP)长度；
PRS的频域资源带宽：这个参数取值是分配给PRS信号的物理资源块(Physical Resource Block，PRB)个数，PRS资源带宽最小值是24个PRB，颗粒度是4个PRB，而最大值是272个PRB；
PRS资源的频域起始频率位置：这个参数定义来PRS信号在频域分配的起始PRB的索引号，PRB的索引号是相对于PRS的点A(PointA)所定义的；
PRS信号的频域参考点PointA；
PRS信号的梳齿(comb)尺寸Comb-N。
在每个定位频率层(PFL)里面所配置的上述PRS参数会应用在这个定位频率层(PFL)所包含的所有PRS资源上。也就是说，在一个定位频率层(PFL)里面，来自多个不同TRP的所有PRS信号会使用同样的子载波间隔和CP长度，同样的梳齿尺寸，发送在同样的频率子带上，并且占用完全一样的带宽。这样的设计可以支持UE能够同时接收并测量发送同样频点上的来自多个不同的TRP的PRS信号。
TRP层的参数包括一个用于唯一识别这个定位TRP的ID参数，这个TRP的物理小区ID，这个TRP的NR小区全局标识(NR Cell Global Identity，NCGI)以及这个TRP的绝对无线频道编号(Absolute Radio Frequency Channel Number，ARFCN)。每个TRP层里面可以最多配置2个DL PRS资源集。DL PRS资源集这个层参数配置了以下这些参数，而这些参数会应用到这个资源集里面所包含的所有的DL PRS资源：
DL PRS资源集合识别ID(nr-DL-PRS-ResourceSetID)；
DL PRS的传输周期和时隙偏移(dl-PRS-Periodicity-and-ResourceSetSlotOffset)：这个参数定义了包含在这个DL PRS资源集里面的所有DL PRS资源的时域发送行为；可以配置的DL PRS的传输周期最小值是4毫秒，而最大值是10240毫秒；DL PRS的配置支持灵活的子载波间隔，包括15KHz，30KHz，60KHz和120KHz；在不同的子载波间隔情况下，可以配置的DL PRS传输周期值范围是一样的；
DL PRS资源的重复因子(dl-PRS-ResourceRepetitionFactor)：这个参数定义了一个PRS资源在每个PRS周期内的重复传输次数，同一个DL PRS资源的重复传输可以被UE用来聚合多次传输的DL PRS信号能量从而可以增加DL PRS的覆盖距离和增加定位精度，在FR2系统中，DL PRS资源的重复传输被UE用来做接收波束扫描操作；UE可以用不同的接收波束来接收同一个DL PRS资源的重复传输从而找到最佳的TRP发送波束和UE接收波束匹配；另外一方面，DL PRS资源的重复发送会增加PRS的开销，在R16的规范中，DL PRS资源的重复因子取值为1，2，4，6，8，16和32。
DL PRS资源重复发送的时间间隔(dl-PRS-ResourceTimeGap)：这个参数定义了同一个PRS资源的连续两次重复传输之间的时隙数；
DL PRS的静默(muting)配置：这个参数用来定义DL PRS信号在某些分配时频资源上不发送(称为muting)，Muting是指DL PRS信号并不会在所有的分配的时频资源上发送，而是有意在某些指定的时频资源上不发送，这么做的目的一方面可以规避和其他信号比如SSB的冲突，另一方面可 以规避不同TRP发送的信号之间的干扰，例如有意在某些时刻上关掉某个TRP的DL PRS发送从而使得UE能够收到来自较远的TRP的DL PRS信号，PRS的muting操作将在后续的描述中做详细解释，这里就不做赘述了。
DL PRS资源所占的OFDM符号数(dl-PRS-NumSymbols)：定义了一个DL PRS资源在一个时隙内部所分配的正交频分复用(Orthogonal frequency-division multiplexing，OFDM)符号数量。
如前所述，在一个DL PRS资源集这层配置里面所配置的所有参数会应用到这个资源集里面所包含的所有DL PRS资源。因此，在同一个DL PRS资源集里面的所有的DL PRS资源会以同样的周期发送，同样的重复传输次数，以及占用同样数量的OFDM符号。
每个DL PRS资源会配置如下的参数：
一个DL PRS资源识别ID(nr-DL-PRS-ResourceID)；
DL PRS的序列ID(dl-PRS-SequenceID)；
DL PRS的起始频域资源单元偏移(dl-PRS-CombSizeN-AndReOffset)：这个参数定义了DL PRS资源在一个时隙内的第一个分配的OFDM符号上资源映射所用的频域资源单元偏移值，根据这个参数以及相对偏移值，UE就可以确定每个OFDM符号上资源映射所使用的频域资源单元偏移值；
DL PRS的资源时隙偏移(dl-PRS-ResourceSlotOffset)：这个参数定义相对于DL PRS资源集的时隙偏移，这个参数可以确定每个DL PRS资源所处的时隙位置；
DL PRS的OFDM符号偏移(dl-PRS-ResourceSymbolOffset)：这个参数定义了一个DL PRS资源在一个时隙内的时频资源分配位置，它指示的在一个时隙内的起始OFDM符号索引号；
DL PRS的QCL信息(dl-PRS-QCL-Info)：这个参数提供了DL PRS信号的准共址信息(Quasi Co-Location，QCL)。
为便于更好的理解本申请实施例，对本申请相关的侧行(sidelink)定位进行说明。
在侧行(sidelink)定位的out-of-coverage场景，起着与gNB或TRP作用类似的锚点设备和定位目标终端都处于与5G系统无连接的状态下。该种情况下，它们的参考信号(如侧行定位参考信号(sidelink positioning reference signals，S-PRS))不受LMF实体所管控。在out-of-coverage场景下，系统通过锚点设备对定位目标终端发送的S-PRS执行测量，或者目标终端对锚点设备发送的S-PRS执行测量，结合锚点设备的位置信息，系统完成定位。
为便于更好的理解本申请实施例，对本申请所解决的问题进行说明。
out-of-coverage场景下，终端无法知晓选择到的锚点设备是否已经在传输S-PRS，或者各锚点(anchor)设备自行选择或者已在进行发送的PRS是否具有冲突(collision)的情况，如果出现冲突(collision)，需要一定的机制予以规避。
基于上述问题，本申请提出了一种终端定位方案，终端设备可以确定不同锚点设备的用于定位的参考信号的配置是否冲突，在配置冲突的情况下设计了规避冲突的方法，从而可以确保终端设备的精准定位。
以下通过具体实施例详述本申请的技术方案。
图3是根据本申请实施例的无线通信的方法200的示意性流程图，如图3所示，该无线通信的方法200可以包括如下内容中的至少部分内容：
S210，终端设备确定M个锚点设备的第一参考信号的配置是否冲突，M为正整数；
S220，该终端设备为该M个锚点设备中部分或全部的锚点设备重新分配该第一参考信号的配置信息；或者，该终端设备指示该M个锚点设备继续使用已有的该第一参考信号的配置信息。
在本申请实施例中，锚点设备可以是用于辅助终端定位的、在侧行链路上可以发送参考信号或者对接收的参考信号进行测量的设备。
在本申请实施例中，“锚点设备”也可以称之为“锚点终端”或“其他终端”，本申请对此并不限定。
在一些实施例中，M个锚点设备可以是终端设备选取或确定的。在另一些实施例中，M个锚点设备可以是网络设备选取或确定并指示给终端设备的。
在一些实施例中，该第一参考信号为用于定位的参考信号。当然，该第一参考信号也可以是其他参考信号，本申请对此并不限定。
在一些实施例中，该第一参考信号为侧行定位参考信号(S-PRS)。
在一些实施例中，上述S220中，在配置冲突的情况下，该终端设备为该M个锚点设备中部分或全部的锚点设备重新分配该第一参考信号的配置信息。具体例如，该M个锚点设备中部分或全部的锚点设备的第一参考信号的配置冲突，此种情况下，该终端设备为该M个锚点设备中部分或全部的锚点设备重新分配该第一参考信号的配置信息。
在一些实施例中，上述S220中，在配置不冲突的情况下，该终端设备指示该M个锚点设备继续 使用已有的该第一参考信号的配置信息。具体例如，该M个锚点设备中的全部锚点设备的第一参考信号的配置均不冲突，此种情况下，该终端设备指示该M个锚点设备继续使用已有的该第一参考信号的配置信息。可选地，该终端设备通过专用信令指示或告知该M个锚点设备继续使用已有的该第一参考信号的配置信息。
在一些实施例中，该终端设备可以通过广播或专用信令获取该第一参考信号的配置信息。具体例如，锚点设备可以向具有定位需求的终端设备发送S-PRS的配置信息，如通过侧行专用信令或者广播中搭载S-PRS的配置信息。这么操作可以有利于终端设备第一时间获取各锚点设备的S-PRS配置参数，判断各锚点设备的S-PRS参数设置是否冲突或是否具有碰撞。
在一些实施例中，对于未配置有第一参考信号的配置信息的锚点设备，终端设备可以为此类锚点设备配置第一参考信号的配置信息。具体例如，在该M个锚点设备中包括第二锚点设备，且该第二锚点设备未配置该第一参考信号的配置信息的情况下，该终端设备为该第二锚点设备配置该第一参考信号的配置信息。
在一些实施例中，该终端设备接收第一信息，该第一信息用于指示对应的锚点设备的该第一参考信号的配置信息是否允许被修改或更新。例如，终端设备接收锚点设备1发送的第一信息，该第一信息用于指示该锚点设备1的该第一参考信号的配置信息是否允许被修改或更新。
可选地，该终端设备接收该M个锚点设备中部分或全部的锚点设备分别发送的该第一信息。具体例如，该第一信息通过广播或者专用信令承载。
具体的，锚点设备可以通过广播专有信令告知终端设备其配置的S-PRS参数是否可以被修改或更新(在一定情况下，配置是不可以被改变的，比如参数配置来源于其他正在定位的终端或者gNB)。
在一些实施例中，在该M个锚点设备中包括第一锚点设备，且该第一锚点设备发送的该第一信息指示该第一锚点设备的该第一参考信号的配置信息不允许被修改或更新的情况下，重新分配了该第一参考信号的配置信息的锚点设备中不包括该第一锚点设备。也即，对于第一参考信号的配置信息不允许被修改或更新的锚点设备，终端设备不为其重新分配第一参考信号的配置信息。或者，对于第一参考信号的配置信息不允许被修改或更新的锚点设备，可以拒绝或忽略终端设备为其重新分配第一参考信号的配置信息。
在一些实施例中，该终端设备将该第一锚点设备的优先级设置为低，或者，该终端设备降低该第一锚点设备的优先级。
在一些实施例中，终端设备选择锚点设备的标准：被选择的锚点设备不能既发送冲突的第一参考信号(如S-PRS)，又标明坚持使用已分配的第一参考信号(如S-PRS)，或者，终端设备将这样的锚点设备设为低优先级的锚点设备。
在一些实施例中，该终端设备接收第二信息；其中，该第二信息用于指示对应的锚点设备配置有该第一参考信号的配置信息。可选地，该终端设备接收该M个锚点设备中部分或全部的锚点设备分别发送的该第二信息。例如，该第二信息通过广播或专用信令承载。又例如，该第二信息通过回复问询的方式发送。
一种实现方式中，锚点设备可以通过回复终端设备问询的方式发送第二信息。另一种实现方式中，锚点设备可以通过回复网络设备问询的方式发送第二信息。
在一些实施例中，该第二信息还用于指示以下至少之一：
对应的锚点设备位于网络覆盖外通信(out-of-coverage)场景，对应的锚点设备已配置的该第一参考信号是自行选择的，对应的锚点设备测得最近的基站(如gNB)的下行路损参考(downlink pathloss reference)的信号强度低于第一阈值，对应的锚点设备测得最高的小区的下行路损参考的信号强度。
需要说明的是，锚点设备测得最近的基站(如gNB)的下行路损参考的信号强度低于第一阈值，则可以间接推导出该锚点设备处于out-of-coverage场景。
在一些实施例中，该信号强度为以下之一：参考信号接收功率(Reference Signal Received Power，RSRP)，参考信号接收质量(Reference Signal Received Quality，RSRQ)，信号干扰噪声比(Signal to Interference plus Noise Ratio，SINR)。
在一些实施例中，该第一阈值由网络设备配置，或者，该第一阈值由协议约定。
具体的，当锚点设备已经配置有第一参考信号(如S-PRS)时，锚点设备可以通过广播或者回复终端问询的方式告知终端其已配置了第一参考信号的配置信息。
因此，在本申请实施例中，终端设备确定M个锚点设备的第一参考信号的配置是否冲突，在配置冲突的情况下终端设备为M个锚点设备中部分或全部的锚点设备重新分配第一参考信号的配置信息，在配置不冲突的情况下终端设备指示M个锚点设备继续使用已有的第一参考信号的配置信息，从而可以确保终端设备的精准定位。
以下通过实施例1和实施例2详述本申请技术方案。
实施例1，如图4所示，终端设备首先收集锚点设备的S-PRS配置信息，之后终端设备判断锚点设备上报的S-PRS配置是否具有冲突情况，如是，终端设备需要为至少一个锚点设备重新分配S-PRS配置参数，以及将重新分配的S-PRS配置参数发送至该至少一个锚点设备。之后可选的，在确认锚点设备启用新的S-PRS配置参数之后，终端设备开启定位。
实施例2，如图5所示，终端设备首先收集锚点设备的S-PRS配置信息，之后终端设备判断锚点设备上报的S-PRS配置是否具有冲突情况，如是，终端设备为某一锚点设备重新分配S-PRS配置参数，然而，该锚点设备拒绝终端设备为其分配的S-PRS配置参数。以及终端设备转而为其他锚点设备重新分配S-PRS配置参数。之后可选的，在确认锚点设备启用新的S-PRS配置参数之后，终端设备开启定位。
