为便于更好的理解本申请实施例，对本申请相关的NR定位技术进行说明。
定位技术是现代通信系统和导航系统的核心技术之一，例如卫星导航系统，蓝牙，WiFi等都提供了定位功能。同样，现代蜂窝通信系统也都支持定位功能，从3G和4G(LTE)系统开始，各种先进的定位技术逐渐都加入到蜂窝通信系统中。在5G(NR)系统中，定位技术同样也会支持，具体标准在版本16(Release 16，R16)被引入。在3GPP R16版本的NR中，引入了下列一些定位技术：
下行链路到达时间差定位法(Downlink Time Difference of Arrival，DL-TDOA)；
上行链路到达时间差定位法(Uplink Time Difference of Arrival，UL-TDOA)；
多个往返时间定位法(Multi Round Trip Time，Multi-RTT)；
下行链路离开角定位法(Downlink Angle of Departure，DL-AoD)；
上行链路到达角定位法(Uplink Angle of Arrival，UL-AoA)；
增强小区标识(ID)定位法。
为了支持各种定位方法，R16NR在下行链路引入了定位参考信号(PRS)，在上行链路引入了用于定位的SRS信号(SRS for positioning)。
基于NR的定位功能，主要涉及三大部分：终端(UE)、多个网络发送接收点(Transmission/Reception Point，TRP)和定位服务器(Location Server)。
其中，多个网络发送接收点可以具有如下特征：
终端周围多个TRP参与蜂窝定位；
一个基站可能是一个TRP；
一个基站下面可能有多个TRP。
定位服务器可以具有如下特征：
定位服务器负责整个定位流程；
定位服务器往往包括定位管理功能(Location Management Function，LMF)实体。
基于下行链路的定位方法，又可以细分为两大类，分别为终端协助的定位方法(UE-assisted)和基于UE的定位方法(UE-based)。
其中，在终端协助的定位方法中，UE负责定位相关测量；网络根据UE上报的测量结果来计算位置信息。
其中，在基于UE的定位方法中，UE进行定位相关测量，并基于测量结果来计算位置信息。
下面以基于下行链路的一种定位(终端协助的定位方法，UE-assisted)方法为例来说明基本流程，如图2所示：
①.定位服务器通知TRP相关配置，其中，可能包括PRS的配置信息，和/或终端需要上报测量结果的类型等；
②.TRP发送定位信号PRS；
③.终端接收定位信号PRS，进行测量；需要说明的是，根据不同的定位方法，终端需要的测量结果也不一样；
④.终端将测量结果反馈给定位服务器，例如，终端将测量结果通过基站反馈给定位服务器；
⑤.定位服务器计算出位置相关信息。
上面是UE-assisted定位方法的一个流程示意，对于基于终端的定位方法(UE-based)，在上述第四步中，终端根据测量结果直接计算出位置相关的信息，不需要把测量结果上报给定位服务器，然后有这个网元来进行计算。在UE-based定位方法下，终端需要知道TRP对应的位置信息，因此网络需要把TRP对应的位置信息提前通知UE。
下面以基于上行链路的一种定位方法为例来说明基本流程，如图3所示：
①.定位服务器通知TRP相关配置；
②.基站发送相关信令给终端；
③.终端根据发送上行信号(SRS for positioning)；
④.TRP进行对SRS for positioning进行测量，并把测量结果发送给定位服务器；
⑤.定位服务器计算出位置相关信息。
根据定位的基本原理可以知道，用于定位的信号的带宽如果增大，理论上可以提高定位精度。一方面，一个NR载波的最大带宽是有限的，例如在频率范围1(Frequency Range 1)，一个NR载波的最大带宽时100MHz。另一方面，运营商的频谱受限，单个载波的频谱可能达不到协议支持的最大带宽。对于不同载波上的定位信号，可以各自独立测 量。另一方面，为了进一步提高定位精度，一种方法把不同载波上用于定位的信号联合使用。
对于不同载波上定位信号可以联合使用，或者说聚合处理：不同载波上的定位信号联合起来看成是一个更大带宽的信号，即把信号聚合起来(aggregation of reference signals),作为一个“聚合的信号”来进行测量。也可以称为NR定位频率层的聚合(Aggregation of NR positioning frequency layers)，或者下行定位信号的聚合(Aggregation of DL PRS)，或者下行定位信号资源的聚合(Aggregation of DL PRS resources)，或者下行定位信号的聚合(Aggregation of DL PRS)，或者1个或多个定位频率层上下行定位信号的聚合(Aggregation of DL PRS in one or more positioning frequency layers)。
这种方法对于两个载波上的时间同步误差、相位连续要求较高；对于信号发送方，以及信号测量方的时延要求很高；终端也需要采用更大的采样率(sampling rate)来实现聚合处理方法。
由于聚合处理方法对于产品实现要求较高，因此为了便于产品实现，需要对相关信号的配置进行相应的优化，一方面可以利用到“聚合”带来的好处，另一方面可以适当降低终端的实现复杂度。
目前还没有看到针对用于定位的信号聚合相关的配置方案。如果对于配置不做任何限制，则可能会存在下列四个方面的问题：
1.终端实现复杂度高；
2.网络优化配置复杂度高；
3.配置信令开销大；
4.性能不佳。
本方案中的各种方法主要是引入下面一个或多个条件，来解决上述一个问题，或同时解决上述多个问题，同时已给出具体的配置信令设计。
以下通过具体实施例详述本申请的技术方案。
图4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4所示，该方法200可以包括如下内容中的至少部分内容：
S210，网络设备向终端设备发送第一信令；其中，该第一信令用于指示一个或多个第一下行定位信号集合，该第一下行定位信号集合包括占用不同的频域资源的多个下行定位信号，该多个下行定位信号用于实现联合使用的定位功能；
S220，该终端设备接收该网络设备发送的该第一信令。
需要说明的是，在本申请实施例中，“联合”也可以称之为“聚合(aggregation)”或“绑定(bundling)”。此外，在本申请实施例中，为了方便描述，将用于实现基于多个下行定位信号联合使用的定位功能的多个下行定位信号称之为第一下行定位信号集合，也即，这儿提到的第一下行定位信号集合中的“集合”概念仅为了方便描述而引入，我们把可以用于实现联合使用的定位功能的多个下行定位信号统称为一个“集合”；同时“集合”也不一定会出现在标准协议或者信令中。
在一些实施例中，该第一信令还可以用于指示一个或多个第二下行定位信号集合，该第二下行定位信号集合仅包括一个下行定位信号，此种情况下，对于该第二下行定位信号集合中的下行定位信号，无需像第一下行定位信号集合中的下行定位信号一样联合使用。
在本申请实施例中，终端设备可以实现基于多个下行定位信号实现联合使用的定位功能，例如位置信息的确定，或者定位相关测量，或者定位相关测量以及测量结果的上报，从而，提高定位精度。
在一些实施例中，该下行定位信号包括定位参考信号(PRS)和/或同步信号块(Synchronization Signal Block，SSB)。也即，该第一下行定位信号集合包括多个PRS，或者，该第一下行定位信号集合包括多个SSB，或者，该第一下行定位信号集合包括一个或多个PRS和一个或多个SSB。
需要说明的是，SSB也可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)。
在一些实施例中，该第一信令通过LTE定位协议(LTE Positioning Protocol)传输。此种情况下，重用现有协议流程，标准化工作量小。
在一些实施例中，该网络设备为定位服务器(Location Server)。例如，在该第一信令通过LTE定位协议传输的情况下，该网络设备为定位服务器。
在一些实施例中，在该第一信令通过LTE定位协议传输的情况下，该第一信令可以通过以下信令中的至少一种传输：
NR多RTT提供协助数据(NR-Multi-RTT-ProvideAssistanceData)；
NR下行AoD提供协助数据(NR-DL-AoD-ProvideAssistanceData)；
NR下行TDOA提供协助数据信令(NR-DL-TDOA-ProvideAssistanceData)；
NR下行PRS协助数据信令(NR-DL-PRS-AssistanceData)；
NR选择的下行PRS索引列表(NR-SelectedDL-PRS-IndexList)。
在一些实施例中，该第一信令为无线资源控制(Radio Resource Control，RRC)信令。也即，通过基站直接给终端配置，可以降低配置信息传输/处理带来的时延。
在一些实施例中，该网络设备为该终端设备的服务基站。例如，在该第一信令为RRC信令的情况下，该网络设备为该终端设备的服务基站。
在一些实施例中，该第一信令用于指示至少一个TRP，该至少一个TRP中的TRP对应的部分或全部下行定位信号属于该第一下行定位信号集合。例如，该至少一个TRP中的每个TRP对应的部分或全部下行定位信号属于该第一下行定位信号集合。具体可以参见如下实施例1-0所述。
因为不同的TRP上支持的发送带宽能力不同，因此基于每个TRP来指示下行定位信号联合使用的配置，可以适用更多的实际网络部署场景，提高下行定位信号联合使用的使用概率。
实施例1-0
第一信令指示一个或多个TRP，例如可以是通过指示一个或多个下行PRS标识(dl-PRS-ID)来指示该一个或多个TRP，其中每个不同dl-PRS-ID对应一个相应的TRP。可选的，第一信令可以包含一个序列(SEQUENCE)数据结构来指示一个或多个TRP。可选地，SEQUENCE数据结构最大尺寸(size)可以为256，或者最大size为64，或者最大size为32，或者最大size为16。我们把SEQUENCE数据结构最大size记为maxSize。SEQUENCE数据结构中每个元素类型记为trpInfo。可选地，每个元素指示一个TRP信息，可以为0到255取值，或者为0到63取值，或者1到64取值。在对应的新增域可以表示如下(具体使用的名字只用于示意，可以是其他名字)：
aggregationOfTRP SEQUENCE(SIZE(1..maxSize))OF trpInfo,OPTIONAL
上述实施例1-0中的新增域可以在一些NR定位信息元素中传输。其中，该NR定位信息元素例如可以是NR-Multi-RTT-ProvideAssistanceData，或，NR-DL-AoD-ProvideAssistanceData，或，NR-DL-TDOA-ProvideAssistanceData，或，NR-DL-PRS-AssistanceData，或NR-SelectedDL-PRS-IndexList。
此种情况下，新增域中的“aggregationOfTRP”指示的每个TRP对应的每个定位频率层(Positioning Frequency Layers，PFL)上的下行定位信号都可以聚合或联合使用。例如“aggregationOfTRP”指示一个TRP(记为TRP a)，并且TRP a上配置了定位频率层0(PFL 0)和定位频率层1(PFL 1)，则PFL 0和PFL 1上的信号可以聚合或联合使用。再例如，第一信令指示了一个TRP(记为TRP a)，并且TRP a上配置了定位频率层0(PFL 0)和定位频率层1(PFL 1)，PFL0上有下行定位信号x1,x2,PL1上有下行定位信号x3，x4，则x1和x2可以属于一个第一定位下行信号集合，x3和x4可以属于另一个第一定位下行信号集合，也可能x1、x2、x3和x4都属于一个第一定位下行信号集合。
在一些实施例中，该第一信令用于指示该至少一个TRP中的TRP对应的且属于该第一下行定位信号集合的下行定位信号所属的定位频率层。例如，该第一信令用于指示该至少一个TRP中的每个TRP对应的且属于该第一下行定位信号集合的下行定位信号所属的定位频率层。具体可以参见如下实施例1-0A和实施例1-0D所述。
需要说明的是，如果两个定位频率层的频域间隔远，信号聚合或联合使用没有什么增益。因此通过第一信令的指示，可以灵活地把适合下行定位信号聚合或联合使用的定位频率层合在一起，从而给网络配置优化提供更大的空间，从而改善整体性能。
实施例1-0A
在上述实施例1-0的基础上，第一信令还可以指示额外信息，例如针对指示的TRP，同时也指示哪些定位频率层的信号可以聚合。假设一个TRP(记为TRP a)配置了3个定位频率层(记为PFL 0，PFL 1，PFL 2)。可选的，第一信令指示TRP a，以及其对应的能聚合的定位频率层为FP0和PFL1，则表明TRP a上配置的PFL 0和PFL 1上的信号可以聚合，可选地，PFL 0和PFL 2上的信号不聚合，PFL 1和PFL 2上的信号不聚合。也即，新增域中的“trpInfo”需要即包含TRP指示信息，还要包含定位频率层指示信息。实施例1-0A中的新增域可以如下所示。
aggregationOfTRP SEQUENCE(SIZE(1..maxSize))OF trpInfo,OPTIONAL
在实施例1-0A中，定位频率层指示信息可以包括如下特征：
定位频率层指示信息的取值可以为0,1,2,3，或者取值为1,2,3,4；
定位频率层指示信息的取值为一个整数(记为A1)，表示定位频率层0到定位频率层A1可以聚合，或者表示定位频率层1到定位频率层A1可以聚合，或者表示定位频率层0到定位频率层A1-1可以聚合；
定位频率层指示信息的取值为一个或多个整数(每个都小于4，或者小于等于4)，每个整数对应一个定位频率层。
定位频率层指示信息可以是一个位图(bitmat)，其中取值为1的比特对应的定位频率层可以聚合，或者取值为1的比特对应的定位频率层可以聚合。

上述实施例1-0D中的新增域可以在一些NR定位信息元素中传输。其中，该NR定位信息元素例如可以是NR-Multi-RTT-ProvideAssistanceData，或，NR-DL-AoD-ProvideAssistanceData，或，NR-DL-TDOA-ProvideAssistanceData，或，NR-DL-PRS-AssistanceData，或，NR-SelectedDL-PRS-IndexList。
在一些实施例中，该第一信令用于指示该至少一个TRP中的TRP对应的且属于该第一下行定位信号集合的下行定位信号所属的资源集合索引。例如，该第一信令用于指示该至少一个TRP中的每个TRP对应的且属于该第一下行定位信号集合的下行定位信号所属的资源集合索引。具体可以参见如下实施例1-0B和上述实施例1-0D所述。
本实施例可以做到更精细化的下行定位信号聚合或联合使用，例如两个资源集合，一个资源集合对应一组宽的模 拟波束，另一个资源集合对应窄的模拟波束，这组宽的模拟波束用来做精度相对粗的定位，因此其不需要配置下行定位信号聚合。这组窄的模拟波束用来做精度相对精细的定位，因此其需要配置下行定位信号聚合。这样给了网络更大的自由度来优化下行定位信号的优化，在提高系统性的情况下，降低定位信号占用资源的开销。

在上述实施例1-0和/或实施例1-0A的基础上，第一信令还可以指示额外信息，例如针对指示的TRP，同时也指示哪些资源集合(resource set)中的信号可以聚合。假设一个TRP(记为TRP a)配置了3个定位频率层(记为PFL 0，PFL 1，PFL 2)，每个定位频率层都配置了2个resource set(记为set 0，set 1)。下面有几个可选项：

实施例1-1
假设第一下行定位信号集合中含有2个下行定位信号。对于第一下行定位信号集合中含有更多的下行定位信号的情况，可以直接扩展得到。假设终端设备接收网络设备配置的第一信令，第一信令(例如通过LPP协议)配置了2个下行定位信号组(实施例中都以PRS信号为例来描述)，每组中含有4个PRS信号，例如第一组Set X含有PRS 0_0，PRS 0_1，PRS 0_2，PRS 0_3，第二组Set Y含有PRS 1_0，PRS 1_1，PRS 1_2，PRS 1_3。上述两组信号，分别对应四个第一下行定位信号集合，例如{PRS 0_0,PRS 1_0}属于1个第一下行定位信号集合，{PRS 0_1,PRS 1_1}属于1个第一下行定位信号集合，{PRS 0_2,PRS 1_2}属于1个第一下行定位信号集合，{PRS 0_3,PRS 1_3}属于1个第一下行定位信号集合。
需要注意的是，第一下行定位信号集合并不一定需要显式地配置，它只是为了方便描述两个对应下行定位信号而引入的逻辑概念，例如，如果两个下行定位信号具有对应关系(例如，两个下行定位信号可以联合使用，两个下行定位信号可以聚合在一起，或者两个下行定位信号可以被聚合接收，或者两个下行定位信号被绑定在一起(bundling)等)，则认为这两个下行定位信号属于第一下行定位信号集合。
可选地，在实施例1-1中，两个下行定位信号组的下行定位信号可以是不同的定位频率层上的下行定位信号，例如第0组Set 0中的下行定位信号是定位频率层0上的下行定位信号，第1组Set 1中的下行定位信号是定位频率层1上的下行定位信号。因此，可以利用现有协议配置架构，以及利用部分现有设计，降低信令设计工作量。
可选的，在实施例1-1中，两个下行定位信号组的下行定位信号可以是同一定位频率层上的下行定位信号，例如第0组Set 0和第1组Set 1中的下行定位信号都是定位频率层0上的下行定位信号。因此，可以避免引入定位频率层之间的对应关系，从而降低信令设计复杂度。同时在同一个定位频率层，可以减少很多配置信息，从而可以减少信令开销。
对于每一个第一下行定位信号集合中的两个下行定位信号(后续实施例以{PRS 0_0,PRS 1_0}为例，同样适用于其他第一下行定位信号集合中的信号)，他们在频域上占用不同的资源，例如PRS 0_0和PRS 1_0占用不同的RE，并且他们占用的RE在频域上没有交叉；PRS 0_0和PRS 1_0占用不同的RB，并且他们占用的RB在频域上没有交叉。
可选地，在实施例1-1中，PRS 0_0和PRS 1_0都在同一个测量间隔里，即在测量间隔长度(Measurement Gap Length，可以参见协议TS38.133)的时间内，终端设备可以同时对PRS 0_0和PRS 1_0进行至少一次测量。这个限制的好处有多方面：1.终端设备在一个测量间隔(即在一个测量间隔长度规定的时间内)中同时对PRS 0_0和PRS 1_0进行测量，避免对每个信号都需要一测量间隔，从而降低测量间隔的此处。由于终端在测量间隔中进行测量时，可以停止对其他信号的处理，因此这一限制可以提高系统整体资源利用率，提升系统效率。2.另一方面，避免两个信号测量时间间隔过长，可以降低对于数据存储的需求(一个信号的数据要一直存储，只到另一个信号的数据得到，才能进行聚合处理)，降低终端复杂度。
可选地，在实施例1-1中，PRS 0_0和PRS 1_0时间上间隔可以进一步限定，不仅小于测量间隔长度，还可以限制在一个时隙(slot)内。主要的好处是：进一步缩短两个信号测量时间间隔，可以降低对于数据存储的需求(一个信号的数据要一直存储，只到另一个信号的数据得到，才能进行聚合处理)，降低终端复杂度。
可选地，在实施例1-1中，还可以进一步限定PRS 0_0和PRS 1_0占用同一个时隙内的相同符号。主要的好处：除了和前面提到的降低终端复杂度以外，因为终端可以在相同符号上使用更大带宽直接进行滤波处理，从而可以获得更好的信道估计，提高测量性能。
可选地，在实施例1-1中，PRS 0_0和PRS 1_0对应的符号数目可以相同。例如两个信号对应dl-PRS-NumSymbols的值相等。主要的好处是：因为时域上占用相同的符号，因此可以使用同一个时域滤波器来进行时域上的插值，从而提高信道估计性能，提高测量精度。
以图5为一个示例，两个图分别表示PRS 0_0和PRS 1_0在频域上连续和不连续的情况，后续其他实例中，为了描述简化，往往只描述一种情况，另一种情况可以直接类似得到，不重复赘述。其中在一个时隙内，PRS 0_0和PRS 1_0分别占用相同的4个符号(如图中阴影表示)。可选地，PRS 0_0和PRS 1_0分别占用相同的起始符号。可选地，PRS 0_0和PRS 1_0分别占用相同的符号数目。可选地，PRS 0_0和PRS 1_0分别占用相同的符号。可选地，PRS 0_0和PRS 1_0在同一个slot内。
以图6为一个示例，其中在一个时隙内，PRS 0_0和PRS 1_0分别占用2个符号和4个符号(如阴影表示)。可选地，PRS 0_0和PRS 1_0分别占用相同的起始符号。可选地，PRS 0_0和PRS 1_0在同一个slot内。可选地，符号最少的下行定位信号(PRS 0_0)，其占用符号必须与其他定位下行定位信号(PRS 0_1)重叠。
可选地，在实施例1-1中，PRS 0_0和PRS 1_0对应同一个TRP，例如两个信号对应dl-PRS-ID的值相等。因为 信号聚合需要不同信号之间保持良好的时域同步和频域上相位的连续性，不同TRP如果要满足这一要求，很难实现，因此这一要求一方面可以降低网络实现的复杂度，另一方面可以提高系统整体性能。
可选地，在实施例1-1中，PRS 0_0和PRS 1_0所对应的下行信号组(例如DL PRS resource set)的编号相同，即第一组Set X和第二组Set Y对应的组编号都是0。可选地，PRS 0_0和PRS 1_0在自己所在组内的编号相同，例如PRS 0_0和PRS 1_0在自己所在组内的下行定位信号资源编号都等于A。这两个限定的好处：都是可以通过规则限定信号的对应关系，避免显式的配置信令来指示PRS 0_0和PRS 1_0的对应关系，从而能够降低配置信号开销，提高系统整体性能。另一方面，也可以减少终端解析配置信息的处理，降低终端实现复杂度。
需要说明的是，对于第一下行定位信号集合中包括的多个下行定位信号满足的其他条件，都可以类似描述。不再一一罗列。
在一些实施例中，该第一下行定位信号集合中包括的该多个下行定位信号属于不同的定位频率层(Positioning Frequency Layers，PFL)。可以利用现有协议配置架构，以及利用部分现有设计，降低信令设计工作量。
需要说明的是，定位频率层也可以称为定位层(positioning layer)。
可选地，一个定位频率层上对应的一个或多个下行定位信号属于一个该第一下行定位信号集合。
假设终端设备接收网络设备配置的第一信令，第一信令(例如通过LPP协议)配置了2个定位频率层，假设每个定位频率层上1个下行定位信号组(为了示例简单，所以设为1个)，一共2个下行定位信号组(以PRS信号为例来描述)，每组中含有4个PRS信号，例如第一组Set X含有PRS 0_0，PRS 0_1，PRS 0_2，PRS 0_3，第二组Set Y含有PRS 1_0，PRS 1_1，PRS 1_2，PRS 1_3。上述两组信号，分别对应四个第一下行定位信号集合，例如{PRS 0_0,PRS 1_0}属于1个第一下行定位信号集合，{PRS 0_1,PRS 1_1}属于1个第一下行定位信号集合，{PRS 0_2,PRS 1_2}属于1个第一下行定位信号集合，{PRS 0_3,PRS 1_3}属于1个第一下行定位信号集合。
可选地，该不同的定位频率层在同一个工作频带(例如，NR operating band)内。从而，可以保证聚合信号中多个下行定位信号之间频域上连续，或者间隔较小，提高测量性能；另一方面，可以降低终端的实现复杂度，避免需要使用不同射频通道去接收不同频带上的信号。
在一些实施例中，该第一下行定位信号集合中的该多个下行定位信号之间的对应关系可以通过以下信令之一指示或承载：
NR多RTT提供协助数据(NR-Multi-RTT-ProvideAssistanceData)，NR下行AoD提供协助数据(NR-DL-AoD-ProvideAssistanceData)，NR下行TDOA提供协助数据(NR-DL-TDOA-ProvideAssistanceData)，NR下行PRS协助数据(NR-DL-PRS-AssistanceData)，NR选择的下行PRS索引列表(NR-SelectedDL-PRS-IndexList)，每个频带上NR选择的下行PRS索引列表(NR-SelectedDL-PRS-IndexListPerFreq)。
在一些实施例中，该第一下行定位信号集合包括的下行定位信号与定位频率层之间的对应关系可以通过以下信令之一指示或承载：
NR多RTT提供协助数据(NR-Multi-RTT-ProvideAssistanceData)，NR下行AoD提供协助数据(NR-DL-AoD-ProvideAssistanceData)，NR下行TDOA提供协助数据(NR-DL-TDOA-ProvideAssistanceData)，NR下行PRS协助数据(NR-DL-PRS-AssistanceData)，NR选择的下行PRS索引列表(NR-SelectedDL-PRS-IndexList)，每个频带上NR选择的下行PRS索引列表(NR-SelectedDL-PRS-IndexListPerFreq)。
实施例1-2

可选地，实施例1-2中的新增部分是一个可选(optional)的选项。
可选地，上述“aggregatedFrequencyLayers”以及其对应的取值类型(Type)的表示方法可以有不同选项(可能是如下两种方式之一)。假设nr-DL-PRS-AssistanceDataList-r16中指示了4个不同定位频率层上的信号配置(对应的定位频率层分为记为PFL 0，PFL 1，PFL 2，PFL 3)。
方式1，“aggregatedFrequencyLayers”对应多个定位频率层，例如aggregatedFrequencyLayers取值可以对应2个数0，1，即指示对应上述nr-DL-PRS-AssistanceDataList(倾斜字体表示)中的PFL 0和PFL 1是对应的，即这两个定位频率层上的对应信号可以聚合，或者被聚合接收。此时，可选地，Type类型可以是如下表示形式：SEQUENCE(SIZE(nrMaxFreqLayers))OF INTEGER(0..nrMaxFreqLayers-1)，或者SEQUENCE(SIZE(Z))OF INTEGER(0..nrMaxFreqLayers-1)，Z小于nrMaxFreqLayers，其中nrMaxFreqLayers为现有协议TS37.355V16.2.0(2020-09)中规定的值。与后一个例子相比，好处是可以更灵活，例如可以指示PFL 2和PFL 3对应，或者指示PFL 0和PFL 3对应。又或者例如，“aggregatedFrequencyLayers”取值为2，则即指示对应上述nr-DL-PRS-AssistanceDataList-r16(倾斜字体表示)中前2个频率定位层是对应的，即PFL 0和PFL 1是对应的，这两个定位频率层上的对应信号可以聚合，或者被聚合接收。与前一个例子相比，好处是可以降低信令的比特开销。再例如aggregatedFrequencyLayers可以通过位图来指示对应的定位频率层。
方式2，“aggregatedFrequencyLayers”的取值为1组或多组取值，其中每组取值对应多个定位频率层，例如“aggregatedFrequencyLayers”取值对应{0,1},{2,3}，即指示对应上面nr-DL-PRS-AssistanceDataList-r16(倾斜字体表示)中的PFL 0和PFL 1是对应的，并且PFL 2和PFL 3也是对应的，对应的两个定位频率层上的对应信号可以聚合，或者被聚合接收。可选的，每组取值可以通过bitmap来指示。与上述方式1的方案相比，灵活性更好。在方式1中，只能指示一组可以聚合的定位频率层。而在方式2中，可以指示多组可聚合的定位频率层。例如PFL 0和PFL 1可以是在一个NR工作频带上，PFL 2和PFL 3在另一个NR工作频带上，同一个频带(band)上的定位频率层可以聚合，不同上的不能聚合，则方式2的方案可以灵活指示这种情况。
多个定位频率层的对应关系也可以通过其他定位信息元素传输的示例，例如通过NR-Multi-RTT-ProvideAssistanceData，或NR-DL-AoD-ProvideAssistanceData，或NR-DL-TDOA-ProvideAssistanceData，或NR-SelectedDL-PRS-IndexList，或nr-SelectedDL-PRS-IndexListPerFreq可以直接类似扩展得到，不再一一举例。
在一些实施例中，该第一下行定位信号集合中包括的该多个下行定位信号属于同一个定位频率层。可以避免引入定位频率层之间的对应关系，从而降低信令设计复杂度以及减少信令开销。
在一些实施例中，该第一信令通过以下信令中的至少一种传输：
NR下行PRS的每个频带上的协助数据(NR-DL-PRS-AssistanceDataPerFreq)；
NR下行PRS的每个TRP上的协助数据(NR-DL-PRS-AssistanceDataPerTRP)；
NR下行PRS的信息(nr-DL-PRS-Info)；
NR下行PRS的资源集合(NR-DL-PRS-ResourceSet)；
NR下行PRS的资源(NR-DL-PRS-Resource)。
在一些实施例中，该第一信令包括频域指示信息，该频域指示信息用于指示该第一下行定位信号集合中包括的该多个下行定位信号的频域信息。
可选地，该频域指示信息用于指示以下中的一种或多种：
该多个下行定位信号的频域起始位置，该多个下行定位信号的频域偏移信息，该多个下行定位信号的频域带宽。
在一些实施例中，在NR-DL-PRS-AssistanceDataPerFreq中引入一个或多个频域指示信息，指示每个第一下行定位信号集合中的多个下行定位信号，同一个第一下行定位信号集合中的下行定位信号其他参数相同，只有频域位置分配上不同。可选地，该频域指示信息用于指示该多个下行定位信号的频域偏移信息。例如参见实施例1-3。
在一些实施例中，在NR-DL-PRS-AssistanceDataPerFreq中引入一个或多个下行定位信号带宽信息。例如，参见实施例1-4，实施例1-4A，实施例1-4B。
在一些实施例中，在NR-DL-PRS-AssistanceDataPerTRP中引入一个或多个频域偏移信息，得到每个第一下行定位信号集合中的多个下行定位信号，同一个第一下行定位信号集合中的下行定位信号其他参数相同，只有频域位置分配上不同。例如可以参见实施例1-6。因为不同的TRP上支持的发送带宽能力不同，因此基于每个TRP来描述信号聚合的配置，可以适用更多的实际网络部署场景，提高下行定位信号聚合的使用概率。
在一些实施例中，在NR-DL-PRS-AssistanceDataPerTRP中引入一个或多个下行定位信号带宽信息。例如，参见实施例1-7。
在一些实施例中，在nr-DL-PRS-Info中引入一个或多个频域偏移信息，得到每个第一下行定位信号集合中的多个下行定位信号，同一个第一下行定位信号集合中的下行定位信号其他参数相同，只有频域位置分配上不同。例如可以参见实施例1-9。
在一些实施例中，在nr-DL-PRS-Info中引入一个或多个下行定位信号带宽信息。例如，参见实施例1-10。
在一些实施例中，该第一下行定位信号集合中的多个下行定位信号通过NR-DL-PRS-ResourceSet指示。可以做到更精细化的下行定位信号聚合，例如两个set，一个对应一组宽的模拟波束，一组对应窄的模拟波束，这组宽的模拟波束用来做精度相对粗的定位，因此其不需要配置下行定位信号聚合。这组窄的模拟波束用来做精度相对精细的定位，因此其需要配置下行定位信号聚合。这样给了网络更大的自由度来优化下行定位信号的优化，在提高系统性的情况下，降低定位信号占用资源的开销。
在一些实施例中，在NR-DL-PRS-ResourceSet中引入一个或多个频域偏移信息，得到每个第一下行定位信号集合中的多个下行定位信号，同一个第一下行定位信号集合中的下行定位信号其他参数相同，只有频域位置分配上不同。例如可以参见实施例1-12。
在一些实施例中，在NR-DL-PRS-ResourceSet中引入一个或多个下行定位信号带宽信息。例如，参见实施例1-13。
在一些实施例中，该第一下行定位信号集合中的多个下行定位信号通过NR-DL-PRS-Resource指示。可以做到更精细化的下行定位信号聚合，例如可以基于不同的波束来进行聚合，即一个Resource可以对应一个模拟波束，在有的模拟波束上可以配置下行定位信号聚合，有的模拟波束上可以不配置下行定位信号聚合。从而给了网络更大的自由度来优化下行定位信号的优化，在保证系统性的情况下，降低定位信号占用资源的开销。
在一些实施例中，在NR-DL-PRS-Resource中引入一个或多个频域偏移信息，得到每个第一下行定位信号集合中的多个下行定位信号，同一个第一下行定位信号集合中的下行定位信号其他参数相同，只有频域位置分配上不同。例如可以参见实施例1-15。
在一些实施例中，在NR-DL-PRS-Resource中引入一个或多个下行定位信号带宽信息。例如，参见实施例1-16。
在一些实施例中，该频域偏移信息用于指示不同的下行定位信号之间的频域间隔。例如可以参见实施例1-20。
在一些实施例中，该频域偏移信息用于指示该多个下行定位信号中除第一下行定位信号之外的下行定位信号与该第一下行定位信号之间的频域间隔。例如可以参见实施例1-21。
在一些实施例中，该频域偏移信息用于指示该多个下行定位信号中相邻起始位置之间的频域间隔。例如可以参见实施例1-22。
在一些实施例中，该第一信令中指示一个或多个TRP对应的下行定位信号。
例如，在NR-DL-PRS-AssistanceDataPerFreq中指示一个或多个当前TRP对应的下行定位信号。参见实施例1-5。
例如，在NR-DL-PRS-AssistanceDataPerTRP中指示一个或多个当前TRP对应的下行定位信号。参见实施例1-8。

在一些实施例中，该多个下行定位信号的等效总带宽为该多个下行定位信号中的最低频率位置和最高频率位置之间的带宽。例如，将该多个下行定位信号的等效总带宽为该多个下行定位信号中的最低频率位置和最高频率位置之间的带宽，定义为等效总带宽第二方式。例如，可以参见实施例1-19。考虑聚合信号横跨的所有带宽，能够更贴近实际硬件实现，降低对终端的处理要求，为终端实现提供更大的灵活性，从而可以让更多的终端支持这一特性。
实施例1-18
以两个下行定位信号聚合为例(假设记为PRS 0，PRS 1)，可以扩展到更多个定位信号聚合的情况。假设PRS 0信号带宽为X(单位可以为RB，或者赫兹，或者兆赫兹Mhz，不做限定)，PRS 1信号带宽为Y，PRS 0和PRS1之间间隔带宽为Z。则按照等效总带宽第一方式(多个下行定位信号的等效总带宽为该多个下行定位信号带宽的和)，PRS 0和PRS 1聚合后等效总带宽为X+Y，如图7所示。
实施例1-19
以两个下行定位信号聚合为例(假设记为PRS 0，PRS 1)，可以扩展到更多个定位信号聚合的情况。假设PRS 0信号带宽为X(单位可以为RB，或者赫兹，或者兆赫兹Mhz，不做限定)，PRS 1信号带宽为Y，PRS 0和PRS1之间间隔带宽为Z。则按照等效总带宽第二方式(多个下行定位信号的等效总带宽为该多个下行定位信号中的最低频率位置和最高频率位置之间的带宽)，PRS 0和PRS 1聚合后等效总带宽为X+Y+Z，如图8所示。
实施例1-20
以第一下行定位信号集合中含有3个下行定位信号为例，三个下行定位信号分别记为S0,S1,S2。偏移信息指示是不同下行定位信号之间的间隔，例如图9中两个偏移信息分别指示的是S1与S0之间的间隔，S2与S1之间的间隔，即S0信号频域上结束位置与S1信号频域上起始位置之间的间隔，S1信号频域上结束位置与S2信号频域上起始位置之间的间隔。其中指示信息指的间隔的单位可以是RB，或者赫兹(Hz)，或者兆赫兹(MHz)，或者其他频域资源的单位，不做限定。与实施例1-21，实施例1-22相比，每个偏移信号指示域对应数值的取值范围更小，可以节约比特数目，降低信令配置开销。
实施例1-21
以第一下行定位信号集合中含有3个下行定位信号为例，三个下行定位信号分别记为S0,S1,S2。偏移信息指示都是以同一个下行定位信号(以S0为例)为参考点，来指示其他下行定位信号与参考点之间的偏移，例如图10中两个偏移信息分别指示的是S1频域上起始位置与S0频域上起始位置之间的偏移，S2频域上起始位置与S0频域上起始位置之间的偏移。与实施例1-20，实施例1-22相比，使用同一个参考点，避免每个信号起始位置的确定依赖于其他信号，从而可以降低终端确定对应信号起始位置的计算复杂度。
实施例1-22
以第一下行定位信号集合中含有3个下行定位信号为例，三个下行定位信号分别记为S0,S1,S2。偏移信息指示是以频域上最近的下行定位信号为参考点，来指示某一下行定位信号与参考点之间的偏移，例如图11中两个偏移信息分别指示的是S1频域上起始位置与S0频域上起始位置之间的偏移，S2频域上起始位置与S1频域上起始位置之间的偏 移。与实施例1-20和实施例1-21相比，可以获得他们各自的部分好处，同时也会失去他们各自的部分优点，是一个在不同好处和优点之间的折中。
