Description

传输参考信号的方法及设备

技术领域
本申请涉及无线通信领域，并且更具体地，涉及一种传输信号的方法和装置。
背景技术
准同位(quasi-colocation，QCL)(QCL也可称作准共址)关系是在长期演进(long term evolution，LTE)协作多点(coordinated multi-point，CoMP)中引入的。两个参考信号关于某个大尺度参数QCL表示可以从一个参考信号的这个大尺度参数推测出另一个参考信号的这个大尺度参数，从而可以让终端基于一个参考信号的接收信息辅助另一个参考信号的接收。在LTE系统中，没有为定位参考信号(positioning reference signal，PRS)之间配置QCL关系。
而未来的第五代(5th generation，5G)系统或新空口(new radio，NR)中存在多个波束，PRS可以在多个波束上发送，如果不配置PRS之间的QCL关系，终端设备采用波束扫描的方式接收定位参考信号，复杂度较高。

作为示例而非限定，在本申请实施例中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是IoT系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。在本申请实施例中，IOT技术可以通过例如窄带(narrow band，NB)技术，做到海量连接，深度覆盖，终端省电。
此外，在本申请实施例中，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。

还应理解，上述图1或图2的定位系统中包括的设备或功能节点只是示例性地描述，并不对本申请实施例构成限定，事实上，图1或图2的定位系统中还可以包含其他与图中示意的设备或功能节点具有交互关系的网元或设备或功能节点，这里不作具体限定。
为了便于理解本申请实施例中提供的传输信号的方法，下面简单介绍本申请实施例中涉及到的几个基本概念：
1、准共站/准共址(quasi-collocation，QCL)假设信息。
QCL假设信息也可以简称为QCL信息，QCL信息用于辅助描述终端设备接收波束赋形信息以及接收流程。QCL信息用于指示两种参考信号之间的QCL关系，其中目标参考信号一般是可以是解调参考信号(demodulation reference signal，DMRS)，CSI-RS等，而被引用的参考信号或者源参考信号一般可以是CSI-RS、TRS、SSB等。
空间相关(spatial relation)信息：用于辅助描述终端设备发射侧波束赋形信息以及发射流程。spatial relation信息用于指示两种参考信号之间的空间发送参数关系，其中目标参考信号一般是可以是DMRS，SRS等，而被引用的参考信号或者源参考信号一般可以是CSI-RS、SRS、SSB等。
应理解，满足QCL关系的两个参考信号或信道的空间特性参数是相同的，从而基于该源参考信号资源索引可推断出目标参考信号的空间特性参数。
还应理解，满足空间相关性信息的两个参考信号或信道的空间特性参数是相同的，从而基于该源参考信号资源索引可推断出目标参考信号的空间特性参数。
其中，空间特性参数包括以下参数中的一种或多种：
入射角(angle of arrival，AoA)、主(dominant)入射角AoA、平均入射角、入射角的功率角度谱(power angular spectrum，PAS)、出射角(angle of departure，AoD)、主出射角、平均出射角、出射角的功率角度谱、终端设备发送波束成型、终端设备接收波束成型、空间信道相关性、网络设备发送波束成型、网络设备接收波束成型、平均信道增益、平均信道时延(average delay)、时延扩展(delay spread)、多普勒扩展(Doppler spread)、多普勒频移(doppler shift)、空间接收参数(spatial Rx parameters)等。
这些空间特性参数描述了源参考信号与目标参考信号的天线端口间的空间信道特性，有助于终端设备根据该QCL信息完成接收侧波束赋形或接收处理过程。应理解，终端设备可以根据QCL信息指示的源参考信号的接收波束信息，接收目标参考信号；这些空间特性参数还有助于终端设备根据该空间相关信息完成发射侧波束赋形或者发射处理过程，应理解，终端设备可以根据空间相关信息指示的源参考信号的发射波束信息，发射目标参考信号。
其中，为了节省网络设备对终端设备的QCL信息指示开销，作为一种可选的实施方式，网络设备可以指示PDCCH或物理下行共享信道(physical downlink shared channel，PDSCH)的解调参考信号与终端设备之前上报的多个参考信号中的一个或多个是满足QCL关系的，例如，该参考信号可以是CSI-RS。这里，每一个上报的CSI-RS资源索引对 应了一个之前基于该CSI-RS资源测量时建立的一个收发波束对。应理解，满足QCL关系的两个参考信号或信道的接收波束信息是相同的，该终端设备可以根据该参考信号资源索引推断出接收PDCCH或PDSCH的接收波束信息。
现有标准中定义了四种类型的QCL，网络设备可以同时给终端设备配置一个或多种类型的QCL，如QCL type C，QCL type D，QCL type A+D，QCL type C+D：
QCL type A：多普勒频移(Doppler shift)，多普勒扩展(Doppler spread)，平均延时(average delay)，延时扩展(delay spread)；
QCL type B：多普勒频移，多普勒扩展；
QCL type C：平均延时，延时扩展
QCL type D：空间接收参数(Spatial Rx parameter)。
本申请中所涉及的定位相关的QCL类型主要包括：QCL type A、QCL type D、QCL type A+D、QCL type C或QCL type C+D中的至少一种。
2、波束(beam)。
波束是一种通信资源，不同的波束可以认为是不同的通信资源。不同的波束可以发送相同的信息，也可以发送不同的信息。波束可以对应时域资源、空间资源和频域资源中的至少一项。
可选地，具有相同或者类型的通信特征的多个波束可以视为一个波束，一个波束内可以包括一个或多个天线端口，用于传输数据信道，控制信道和探测信号等。例如，发送波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布；接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。
具体地，波束可以是宽波束，也可以是窄波束，还可以是其他类型的波束。形成波束的技术可以是波束成型技术也可以是其他技术手段，本申请对此不进行限定。其中，波束成型技术(beam forming)可以是通过在空间上朝向特定的方向来实现更高的天线阵列增益。此外，波束可以分为网络设备的发送波束和接收波束，与终端设备的发送波束和接收波束。网络设备的发送波束用于描述网络设备接收侧波束赋形信息，网络设备的接收波束用于描述网络设备接收侧波束赋形信息。终端设备的发送波束用于描述终端设备发送侧波束赋形信息，终端设备的接收波束用于描述接收侧波束赋形信息。
更具体地，波束成型技术包括数字波束成型技术、模拟波束成型技术和混合数字模拟波束成型技术。其中，模拟波束成型技术可以通过射频实现，例如，一个射频链路(RF chain)通过移相器来调整相位，从而控制模拟波束方向的改变。因此，一个RF chain在同一时刻只能打出一个模拟波束。此外，基于模拟波束的通信，需要发送端和接收端的波束对齐，否则无法正常传输信号。
应理解，形成一个波束的一个或多个天线端口也可以看作是一个天线端口集。
还应理解，波束还可以通过空间滤波器(spatial filter)或空间传输滤波器(spatial domain transmission filter)体现，换句话说，波束也可以称为“空间滤波器”，其中发射波束称为“空间发射滤波器”，接收波束称为“空间接收滤波器”或“下行空间滤波器”。网络设备的接收波束或终端设备的发送波束还可以称为“上行空间滤波器”，网络设备的发送波束或终端设备的接收波束还可以称为“下行空间滤波器”。最优的N个波束对(beam pair link，BPL)(一个BPL包括一个网络设备的发射波束和一个终端设备的接收波束，或者，一个BPL包括 一个终端设备的发射波束和一个网络设备的接收波束)的选择。用于终端设备基于网络设备的波束扫描实现对网络设备的发射波束和/或终端设备的接收波束的选择，以及，网络设备基于终端设备的波束扫描实现对终端设备的发射波束和/或网络设备的接收波束的选择。
具体地，发射波束可以为网络设备发射波束，也可以为终端设备发射波束。当该发射波束为网络设备发射波束时，网络设备通过不同的发射波束向终端设备发送参考信号，终端设备通过同一个接收波束来接收网络设备通过不同的发射波束发送的参考信号，并基于接收信号确定网络设备的最优发射波束，然后将网络设备的最优发射波束反馈给网络设备，以便于网络设备对发射波束进行更新。当该发射波束为终端设备发射波束时，终端设备通过不同的发射波束向网络设备发送参考信号，网络设备通过同一个接收波束来接收终端设备通过不同的发射波束发送的参考信号，并基于接收信号确定终端设备的最优发射波束，然后将终端设备的最优发射波束反馈给终端设备，以便于终端设备对发射波束进行更新。其中，上述通过不同的发射波束发送参考信号的过程可以称为波束扫描，基于接收信号确定最优发射波束的过程可以称为波束匹配。
接收波束可以为网络设备的接收波束，也可以为终端设备的接收波束。当该接收波束为网络设备的接收波束时，终端设备通过同一个发射波束向网络设备发送参考信号，网络设备采用不同的接收波束接收终端设备发送的参考信号，然后基于接收信号确定网络设备的最优接收波束，以对网络设备的接收波束进行更新。当该接收波束为终端设备的接收波束时，网络设备通过同一个发射波束向终端设备发送参考信号，终端设备采用不同的接收波束接收网络设备发送的参考信号，然后基于接收信号确定终端设备的最优接收波束，以对终端设备的接收波束进行更新。
需要说明的是，对于下行波束的训练，网络设备会配置参考信号资源集合的类型用于波束训练，当为参考信号资源集合配置的重复参数为“on”时，终端设备假设该参考信号资源集合中的参考信号资源使用相同的下行空间滤波器传输，也即使用相同的发送波束传输；此时，一般情况下，终端设备会使用不同的接收波束接收上述参考信号资源集合中的参考信号资源，训练出终端设备最好的接收波束，可选地，终端设备可以上报终端设备测量的最好的N个参考信号资源对应的参考信号的信道质量。当为参考信资源号集合配置的重复参数为“off”时，终端设备不会假设该参考信号资源集合中的参考信号资源使用相同的下行空间滤波器传输，也即不假设网络设备使用相同的发送波束传输参考信号资源，此时终端设备通过测量该集合中参考信号资源对应的参考信号的信道质量在该资源集合中选出最好的N个波束反馈给网络设备，一般情况下，此时，终端设备在此过程中使用相同的接收波束。
3、定位参考信号(positioning reference signal，PRS)。
LTE系统在Rel-9标准化了基于观测到达时间差(observed time difference of arrival，OTDOA)的定位技术。该定位技术主要是通过终端设备接收并测量若干小区发送PRS，计算出参考信号到达时间差(reference signal time difference，RSTD)等测量量，并向演进服务移动定位中心(evolved serving mobile location center，E-SMLC)发送这些测量量。E-SMLC基于接收到的这些测量量，确定终端设备的位置。LTE中的定位需求是为了满足法规要求，特别的，定位需要满足水平定位精度<50m，垂直定位精度能够识别楼层。
NR Rel-16有关PRS设计的最新结论为：基站(或发射端)发送的PRS可由多个资源集(resource set)组成，每个resource set由包含多个资源(resource)。一个resource set内的每个resource都分别对应一个波束，且每个resource都有自己的索引(identify，ID)号。不同resource set中的resource会在同一个波束上发送，终端设备在所有波束上以波束扫描的方式测量PRS将增加PRS测量的时间。
4、OTDOA。
OTDOA定位技术中，多个基站向终端设备发送PRS，而终端设备通过对多个基站发送的PRS进行测量得到信号到达时间信息。终端设备可以将测得的PRS信号达到时间信息上报给定位管理单元，由定位管理单元根据多个基站的地理位置计算出终端设备的地理位置。终端设备也可以根据测得的PRS信号到达时间信息，结合定位管理单元指示的多个基站的地理位置计算出终端设备的地理位置。
OTDOA是根据多个基站与移动终端设备信号传播的时间差值进行定位的技术。例如，三个基站。OTDOA通过测量终端设备到两个基站的无线信号传播时间差来计算移动终端设备到两个基站的距离差。移动终端设备的运动轨迹就是以两个基站为焦点、以其距离差为定差的双曲线。要实现精确定位还必须对另外两个基站进行相同的测量与计算，以获得另外一条双曲线。由于网络已知服务小区(也可以称为服务基站)到移动终端设备的传播延迟，因此可以从移动终端设备提供的OTDOA测量值，估算出基站到移动终端的距离。三个基站构成的不同圆的交点就是估算出来的终端位置。
在LTE Rel-14讨论的增强机器类通信(enhance machine class communication，eMTC)OTDOA增强中，因为eMTC的终端设备下行带宽是1.4MHz，设计了专门为eMTC UE使用的1.4MHz带宽的PRS。同时，应用于移动宽带(mobile broadband，MBB)的终端设备的PRS也在正常发送。因此，LTE Rel-14中定义了一个小区可配3个不同带宽的PRS，且这3个PRS可独立配置周期等其他参数，现有LTE中没有为PRS间配置QCL关联。而NR系统中存在多个波束，PRS会在多个波束上发送。如果不配置QCL关联，会因为需要训练接收波束而延长PRS的测量，进而影响定位效率。
5G系统或新空口NR中的定位需求包括法规需求和商业场景需求。法规需求与LTE的定位需求一样；而对于商业场景需求，定位需要满足室外水平定位精度<10m，垂直定位精度<3m(待定)，室内水平定位精度<3m，垂直定位精度<3m(待定)。相对于LTE的单一需求，5G不仅支持多级的需求，而且在商业场景需求上，也比LTE时要严格得多。

以下，不失一般性，以网络设备与终端设备之间的交互为例详细说明本申请实施例提供的传输信号的方法。
本申请实施例提供了一种传输信号的方法，通过向终端设备提供定位参考信号的QCL配置，辅助终端设备确定定位参考信号的接收波束，能够降低终端设备做接收波束扫描的开销。下面将结合图3详细描述本申请实施例。
图3是本申请实施例提供的一种传输信号的方法示意性流程图。执行主体包括终端设备和网络设备。
该传输信号的方法包括以下步骤。
S310、网络设备向终端设备发送第一PRS资源集合。
可选的，在一种可能的实现方式中，网络设备可以直接向终端设备发送第一PRS资源集合。在另一种可能的实现方式中，网络设备还可以向终端设备发送第一配置信息，该第一配置信息用于指示第一PRS资源集合，终端设备根据第一配置信息获取该第一PRS资源集合。
S320、网络设备向终端设备发送第二PRS资源集合。
可选的，在一种可能的实现方式中，网络设备可以直接向终端设备发送第二PRS资源集合。在另一种可能的实现方式中，网络设备还可以向终端设备发送第二配置信息，该第二配置信息用于指示第二PRS资源集合，终端设备根据第二配置信息获取该第二PRS资源集合。上述第一配置信息和第二配置信息可以为同一配置信息，也可以为不同的配置信息。
应理解，本申请实施例中对于网络设备向终端设备发送上述的第一PRS资源集合和第二PRS资源集合的先后不做任何限定，例如，可以是网络设备向终端设备发送上述的第一PRS资源集合之后，网络设备再向终端设备发送上述的第二PRS资源集合；或者，可以是网络设备向终端设备发送上述的第一PRS资源集合之前，网络设备再向终端设备发送上述的第二PRS资源集合；或者，网络设备同时向终端设备发送上述的第一PRS资源集合和第二PRS资源集合。
可选地，本申请实施例中涉及的网络设备包括包括图1中所示的LMF或图2中所示的LMC和LMF。
还应理解，本申请实施例中对于网络设备如何向终端设备发送上述的PRS资源集合并不限制，可以参考现有协议中的规定，或者，还可以是在通信技术发展以后网络设备向终端设备发送PRS资源集合的方式。
作为一种可能的实现方式，上述的第一PRS资源集合中包括M个第一PRS资源，该 M个第一PRS资源在M个发送波束上依次发送；第二PRS资源集合中包括M个第二PRS资源，该M个第二PRS资源在上述的M个发送波束上依次发送，M为正整数。
为了便于理解，结合图4简单说明不同的PRS资源集合中的PRS资源对应的发送波束。
图4是本申请实施例提供的一种PRS资源集合中的PRS资源和发送波束相对应的示意图。包括PRS资源集合#1、PRS资源集合#2以及发送波束集合。
从图4中可以看出，PRS资源集合#1包括3个PRS资源(第一PRS资源#1～第一PRS资源#3)、PRS资源集合#2包括3个PRS资源(第二PRS资源#1～第二PRS资源#3)、发送波束集合包括3个发送波束(发送波束#1～发送波束#3)，其中，第一PRS资源#1和第二PRS资源#1均在发送波束#1上发送、第一PRS资源#2和第二PRS资源#2均在发送波束#2上发送、第一PRS资源#3和第二PRS资源#3均在发送波束#3上发送。
具体地，PRS资源集合#1和PRS资源集合#2的周期和带宽不一样，PRS资源集合#1中的第一PRS资源#1～第一PRS资源#3的周期和带宽一样、PRS资源集合#2中的第二PRS资源#1～第二PRS资源#3的周期和带宽一样。目前协议中并未规定不同的参数(例如，周期和/或带宽)配置的PRS资源之间的QCL关系，所以即使上述的第一PRS资源#1和第二PRS资源#1均在发送波束#1上发送，终端设备侧无法获知可以经由同一个接收波束接收上述的第一PRS资源#1和第二PRS资源#1，而是以波束扫描的方式分别接收第一PRS资源#1和第二PRS资源#1分别对应的PRS，从而增加PRS测量的时间。
作为另一种可能的实现方式，第一PRS资源集合中包括P1个第一PRS资源，该P1个第一PRS资源在P1个发送波束上依次发送；第二PRS资源集合中包括P2个第二PRS资源，该P2个第二PRS资源在P2个发送波束上依次发送。其中，P1和P2不相等且均为正整数。
例如，网络设备包括6个用于发送PRS资源的发送波束(波束#1～波束#6)，其中，第一PRS资源集合中包括4个第一PRS资源，该4个第一PRS资源在4个发送波束(波束#1～波束#4)上依次发送，第二PRS资源集合中包括2个第二PRS资源，该2个第二PRS资源在2个发送波束(波束#1～波束#2)上依次发送。
作为另一种可能的实现方式，第一PRS资源集合中包括P3个第一PRS资源，该P3个第一PRS资源在P3#1个发送波束上依次发送；第二PRS资源集合中包括P3个第二PRS资源，该P3个第二PRS资源在P3#2个发送波束上依次发送。P3为正整数，P3#1和P3#2数值相等，但是P3#1个发送波束和P3#2个发送波束部分或全部不相同。
例如，网络设备包括6个用于发送PRS资源的发送波束(波束#1～波束#6)，其中，第一PRS资源集合中包括4个第一PRS资源，该4个第一PRS资源在4个发送波束(波束#1～波束#4)上依次发送，第二PRS资源集合中包括4个第二PRS资源，该4个第二PRS资源在4个发送波束(波束#6～波束#3)上依次发送。
应理解，上述对于第一PRS资源集合和第二PRS资源集合中分别包括的PRS资源可能的形式的描述只是举例，对本申请的保护范围不构成任何限定，本申请中第一PRS资源集合中的N个第一PRS资源分别与第二PRS资源集合中的N个第二PRS资源对应相同的N个发送波束，N为小于或者等M的正整数。
本申请实施例中第一PRS资源集合中的N个第一PRS资源分别与上述第二PRS资源 集合中的N个第二PRS资源满足准共址QCL关系，即图3所示的方法流程还包括：
S330、终端设备确定上述N个第一PRS资源分别与上述N个第二PRS资源满足QCL关系，其中，N为大于或等于1的整数。
图3所示的传输信号的方法，终端设备在接收到第一PRS资源集合和第二PRS资源集合，获知第一PRS资源集合中的N个第一PRS资源分别与第二PRS资源集合中的N个第二PRS资源满足QCL关系之后，用同一个接收波束接收满足QCL关系的两个PRS资源对应的两个PRS，有助于终端设备确定定位参考信号的接收波束，能够降低终端设备做接收波束扫描的开销。
应理解，本申请实施例中N个第一PRS资源分别与N个第二PRS资源一一对应，组成N对PRS资源，该N对PRS资源中每对PRS资源满足QCL关系。
例如，上述N＝1。1个第一PRS资源为第一PRS资源#1；1个第二PRS资源为第二PRS资源#1，第一PRS资源#1和第二PRS资源#1组成1对PRS资源，记为PRS资源组#1，具体地，PRS资源组#1中的第一PRS资源#1和第二PRS资源#1满足QCL关系。
例如，上述N＝3。N个第一PRS资源为第一PRS资源#1、第一PRS资源#2和第一PRS资源#3；N个第二PRS资源为第二PRS资源#1、第二PRS资源#2和第二PRS资源#3，第一PRS资源#1和第二PRS资源#1组成1对PRS资源，记为PRS资源组#1、第一PRS资源#2和第二PRS资源#2组成1对PRS资源，记为PRS资源组#2、第一PRS资源#3和第二PRS资源#3组成1对PRS资源，记为PRS资源组#3，具体地，PRS资源组#1中的第一PRS资源#1和第二PRS资源#1满足QCL关系、PRS资源组#2中的第一PRS资源#2和第二PRS资源#2满足QCL关系、PRS资源组#3中的第一PRS资源#3和第二PRS资源#3满足QCL关系。
进一步地，终端设备可以基于QCL相关参数确定上述N个第一PRS资源分别与上述N个第二PRS资源满足准共址QCL关系，其中，上述QCL相关参数包括以下一种或多种参数：

作为一种可能的实现方式，上述QCL相关参数包括的全部参数为预设的；
作为另一种可能的实现方式，上述QCL相关参数包括的全部参数由网络设备配置；
作为又一种可能的实现方式，上述QCL相关参数包括的部分参数为预设的，剩余的部分参数由网络设备配置。

示例性地，终端设备和网络设备可以将上述的预设的参数保存在终端设备和网络设备本地存储系统中。
应理解，上述方式一和方式二可以结合，例如，上述QCL类型、上述第一PRS资源 集合的索引为网络设备通过配置参数配置的、上述第二PRS资源集合的索引、N个第一PRS资源的索引、N个第二PRS资源的索引为预设的参数。或者，上述第一PRS资源集合的索引、上述第二PRS资源集合的索引、N个第一PRS资源的索引、N个第二PRS资源的索引为网络设备通过配置参数配置的，上述QCL类型为预设的参数。
一种可能的实现方式，当上述的QCL相关参数包括QCL类型、上述第一PRS资源集合的索引、上述第二PRS资源集合的索引的情况下，终端设备基于该QCL相关参数确定上述N个第一PRS资源分别与上述N个第二PRS资源满足准共址QCL关系，包括：
第一PRS资源集合中包括N个第一PRS资源，该N个第一PRS资源在N个发送波束上依次发送；第二PRS资源集合中包括N个第二PRS资源，该N个第二PRS资源在上述的N个发送波束上依次发送；
第一PRS资源集合中的N个第一PRS资源和第二PRS资源集合中的N个第二PRS资源分别满足QCL关系，即终端设备在获知上述的QCL类型、上述第一PRS资源集合的索引、上述第二PRS资源集合的索引的情况下能够确定N个第一PRS资源分别与上述N个第二PRS资源满足QCL关系。
可选地，N个第一PRS资源分别与上述N个第二PRS资源满足QCL关系可以是上述N个第一PRS资源的索引分别与上述N个第二PRS资源的索引相同；或者，
上述N个第一PRS资源在上述第一PRS资源集合中的顺序分别与上述N个第二PRS资源在上述第二PRS资源集合中的顺序相同；或者，
上述N个第一PRS资源分别与上述N个第二PRS资源具有指定的QCL关系，该指定的QCL关系可以由协议预设或者网络设备配置。
例如，第一PRS资源集合的索引为PRS资源集合#1、第二PRS资源集合的索引为PRS资源集合#2，第一PRS资源集合中包括3个第一PRS资源，与第二PRS资源集合中包括的3个第二PRS资源满足QCL关系，该3个第一PRS资源与3个第二PRS资源一一对应，一一对应可以是索引相同，或者在PRS资源集合中的资源顺序相同，或者其他一一对应方式，本申请对此并不限定。
又例如，第一PRS资源集合的索引为PRS资源集合#1、第二PRS资源集合的索引为PRS资源集合#2，第一PRS资源集合中包括1个第一PRS资源，与第二PRS资源集合中包括的1个第二PRS资源满足QCL关系，该1个第一PRS资源与1个第二PRS资源对应，该对应可以是索引相同，或者在PRS资源集合中的资源次序相同，或者具有指定的对应关系，本申请对此并不限定。则上述的QCL相关参数包括：

也就是说，终端设备获知上述的QCL相关参数之后，基于PRS资源集合的索引PRS资源集合#1、PRS资源集合#2能够获知PRS资源集合#1、PRS资源集合#2分别对应的第一PRS资源集合中所有的PRS资源分别和第二PRS资源集合中所有PRS资源满足QCL关系。应理解，在该实现方式下，第一PRS资源集合中包括的第一PRS资源的个数和第二PRS资源集合中包括的第二PRS资源的个数相同、发送第一PRS资源集合中的第一PRS资源的发送波束和发送第二RS资源集合中的第二PRS资源的发送波束相同，且发送第一PRS资源集合中的第一PRS资源的发送波束的次序和发送第二RS资源集合中的第二PRS 资源的发送波束的次序相同。
另一种可能的实现方式，当上述的QCL相关参数包括QCL类型、上述第一PRS资源集合的索引、上述第二PRS资源集合的索引、N个第一PRS资源的索引和上述N个第二PRS资源的索引的情况下，终端设备基于该QCL相关参数确定上述N个第一PRS资源分别与上述N个第二PRS资源满足准共址QCL关系，包括：
第一PRS资源集合中包括P1个第一PRS资源，该P1个第一PRS资源在P1个发送波束上依次发送；第二PRS资源集合中包括P2个第二PRS资源，该P2个第二PRS资源在上述的P2个发送波束上依次发送；其中，P1、P2为大于或等于N的整数。
第一PRS资源集合中的N个第一PRS资源和第二PRS资源集合中的N个第二PRS资源分别满足QCL关系，N为小于或等于P1、P2的正整数，即终端设备在获知上述的QCL类型、上述第一PRS资源集合的索引、上述第二PRS资源集合的索引、N个第一PRS资源的索引和上述N个第二PRS资源的索引的情况下能够确定N个第一PRS资源分别与上述N个第二PRS资源满足QCL关系。

在该实现方式下，网络设备可以配置两个PRS资源集合中分别包括的一个PRS资源 满足QCL关系，例如，上述的配置参数包括：
QCL类型；

或者，
在该实现方式下，协议可以预定义两个PRS资源集合中分别包括的一个PRS资源满足QCL关系，例如，上述的预设的参数包括：

PRS资源集合#1、PRS资源集合#2。
也就是说，终端设备获知上述的QCL相关参数之后，基于PRS资源集合的索引PRS资源集合#1、PRS资源集合#2能够获知PRS资源集合#1、PRS资源集合#2分别对应的第一PRS资源集合中所有的PRS资源分别和第二PRS资源集合中所有PRS资源满足QCL关系。或者，基于PRS资源集合的索引PRS资源集合#1、PRS资源集合#2能够获知PRS资源集合#1、PRS资源集合#2中一个或多个第一PRS资源分别和第二PRS资源集合中一个或多个第二PRS资源满足QCL关系。应理解，在该实现方式下，第一PRS资源集合中包括的第一PRS资源的个数和第二PRS资源集合中包括的第二PRS资源的个数相同、发送第一PRS资源集合中的第一PRS资源的发送波束和发送第二RS资源集合中的第二PRS资源的发送波束相同，且发送第一PRS资源集合中的第一PRS资源的发送波束的次序和发送第二RS资源集合中的第二PRS资源的发送波束的次序相同。
另一种可能的实现方式，当上述的QCL相关参数包括上述第一PRS资源集合的索引、上述第二PRS资源集合的索引、N个第一PRS资源的索引和上述N个第二PRS资源的索引的情况下，终端设备基于该QCL相关参数确定上述N个第一PRS资源分别与上述N个第二PRS资源满足准共址QCL关系，包括：

例如，第一PRS资源集合的索引为PRS资源集合#1、第二PRS资源集合的索引为PRS资源集合#2，第一PRS资源集合中的3个第一PRS资源分别与第二PRS资源集合中的3个第二PRS资源满足QCL关系。该3个第一PRS资源的索引分别为PRS资源#1、PRS资源#2、PRS资源#3；该3个第二PRS资源的索引也分别为PRS资源#1、PRS资源#2、PRS资源#3，相同资源索引的PRS资源满足QCL关系。则上述的QCL相关参数包括：
PRS资源集合#1、PRS资源集合#2；
PRS资源#1、PRS资源#2、PRS资源#3。
终端设备获知上述的QCL相关参数之后，基于PRS资源集合的索引PRS资源集合#1、PRS资源集合#2能够获知PRS资源集合#1、PRS资源集合#2分别对应的第一PRS资源集合和第二PRS资源集合中有PRS资源满足QCL关系，进一步地，终端设备基于PRS资源的索引PRS资源#1、PRS资源#2、PRS资源#3能够获知第一PRS资源集合中索引分别 为PRS资源#1、PRS资源#2、PRS资源#3的3个PRS资源，分别与第二PRS资源集合中索引分别为PRS资源#1、PRS资源#2、PRS资源#3的3个PRS资源满足QCL关系。应理解，在该实现方式下，第一PRS资源集合中包括的第一PRS资源的个数和第二PRS资源集合中包括的第二PRS资源的个数可以不同、发送第一PRS资源集合中的第一PRS资源的发送波束和发送第二RS资源集合中的第二PRS资源的发送波束部分相同，且发送第一PRS资源集合中的第一PRS资源的发送波束的次序和发送第二RS资源集合中的第二PRS资源的发送波束的次序可以不同。

又例如，第一PRS资源集合的索引为PRS资源集合#1、第二PRS资源集合的索引为PRS资源集合#2，第一PRS资源集合中的1个第一PRS资源分别与第二PRS资源集合中的1个第二PRS资源满足QCL关系。该1个第一PRS资源的索引为PRS资源#1；该1个第二PRS资源的索引为PRS资源#3，第一PRS资源#1与第二PRS资源#3具有指定的QCL关系，则上述的QCL相关参数包括：
PRS资源集合#1、PRS资源#1；

终端设备获知上述的QCL相关参数之后，基于PRS资源集合的索引PRS资源集合#1、PRS资源集合#2能够获知PRS资源集合#1、PRS资源集合#2分别对应的第一PRS资源集合和第二PRS资源集合中有PRS资源满足QCL关系，进一步地，终端设备基于PRS资源的索引PRS资源#1、PRS资源#3能够获知第一PRS资源集合中索引为PRS资源#1的PRS资源，与第二PRS资源集合中索引为PRS资源#3的PRS资源满足QCL关系。应理解，本实现方式仅以第一PRS资源集合中包含1个第一PRS资源，第二PRS资源集合中包含1个第二PRS资源为例进行介绍，本实现方式可以扩展到PRS资源集合#1中存在N个第一PRS资源分别与PRS资源集合#2中的N个第二PRS资源具有指定的QCL关系，其中N为大于或等于1的整数，该指定的QCL关系可以由协议预设或者网络设备配置。
应理解，网络设备侧也可以基于预设的参数获知上述的QCL相关参数，则图3所示方法流程，还包括：
S334、网络设备基于预设的参数获知QCL相关参数。
图3所示的传输信号的方法，网络设备在发送第一PRS资源集合和第二PRS资源集合之前，能够获知第一PRS资源集合中的N个第一PRS资源分别与第二PRS资源集合中 的N个第二PRS资源满足QCL关系，进而可以用同一个发送波束发送满足QCL关系的两个PRS资源对应的两个PRS，有助于网络设备确定定位参考信号的发送波束。
网络设备基于预设的参数获知QCL相关参数的具体方式与终端设备基于预设的参数获知QCL相关参数类似，这里不再赘述。或者，在网络设备发送上述的配置参数之前，网络设备基于发送第一PRS资源集合中的第一PRS资源和第二PRS资源集合中的第二PRS资源的发送波束，获知上述的QCL相关参数。则图3所示方法流程，还包括S333、网络设备确定配置参数。

情况一：
由于第一PRS资源和第二PRS资源占用的RE全部重叠或者部分重叠，导致第一PRS资源和第二PRS资源自然是满足QCL关系的，在该情况下，无需基于上述的QCL相关参数确定第一PRS资源和第二PRS资源满足QCL关系。
情况二：
