背景技术
在无线通信定位中，无线信号的反射和折射，导致除首径外，还会存在多条延迟到达的路径，称为多径(multipath)现象。
多径现象下，当测量所得的首径相对于其余径的功率很低时，此时的首径实际上可能是噪声或者干扰，针对首径，无论应用时延或角度测量算法，均很难取得好的定位效果。因此，测量端通常不仅需要上报首径的信息，还需要上报除了首径以外的多条路径的信息，从而为位置解算端提供更多的选择。

在无线通信定位中，无线信号的反射和折射，导致除首径外，还会存在多条延迟到达的路径，称为多径(multipath)现象。更严重时，由于信号收发端侧间的无线信道存在障碍物遮挡，会出现没有直射径的情况，称为非视距(Non Line of Sight，NLOS)现象。多径和非视距现象均会对定位精度造成影响。
目前的定位技术中，获取直射径的信息是必须的，对于NLOS现象，可以通过一些识别消除手段来减小其带来的影响。而对于多径现象，当测量所得的首径相对于其余径的功率很低时，此时的首径实际上可能是噪声或者干扰，针对首径，无论应用时延或角度测量算法，均很难取得好的定位效果。为了解决这一问题，相关技术提出除了上报首径的信息，还需要上报除了首径以外的多条路径的信息，如此上报存在两点优势，一是为位置解算端提供更多的选择，真实的LOS(Line of Sight，视距)径很可能包含在上报的多条路径中，位置解算端可以通过优化算法(例如残差法)提取出来；二是上报的多条路径的信息能够体现与待定位终端所处位置有关的无线信道特性，例 如多条路径的信息中可以包含几何信息，该信息与用户位置存在对应关系，可以通过人工智能(Artificial Intelligence，AI)等算法训练出合适的模型，通过模型得到不受多径干扰的位置结果。但是，多条路径的信息上报带来一个问题，即如何选择除首径之外的路径进行信息上报。显然，路径挑选原则对于后续定位会产生重大影响。
对此，本公开提供一种信息传输方法，应用于定位场景下的测量端，具体在上行定位场景下，测量端可以是基站，在下行定位场景下，测量端可以是终端，在上下行联合定位场景下，可以存在两个测量端，其中一个为基站，另一个为终端。下述实施例提供的方法，可应用于上行定位场景，也可应用于下行定位场景，还可以应用于上下行联合定位场景。
图1是本公开提供的信息传输方法的流程示意图之一，如图1所示，该方法包括：
步骤110，确定多个第一路径的功率参量，所述多个第一路径为所述测量端检测参考信号所得的除首径以外的其他路径。
具体地，在进行定位时，测量端可以通过检测参考信号得到多个路径，此处的所指的多个路径包括首径和第一路径，其中，首径即测量端检测参考信号得到的多个路径中的首径，首径具体是多个路径中最早被测量端检测到的路径，多个路径中，除首径之外的其他路径均可记为第一路径。
针对各个第一路径，均可检测得到该第一路径的功率参量，此处的功率参量用于反映第一路径的功率大小，具体可以反映第一路径的相对功率大小，此时功率参量可以是第一路径的功率和参考功率的比值，例如第一路径的功率与首径的功率的比值，又例如第一路径的功率和所有路径的功率之和的比值；功率参量也可以反映第一路径的绝对功率大小，此时功率参量可以是第一路径的绝对功率值。
需要说明的是，上行定位场景中，测量端为基站，参考信号即信道探测参考信号(Sounding Reference Signal，SRS)，终端向基站发送SRS，基站检测SRS即可得到多个路径。下行定位场景中，测量端为终端，参考信号即定位参考信号(Positioning Reference Signal，PRS)。基站向终端下发 PRS，终端检测PRS即可得到多个路径的相关信息。上下行联合定位场景中，基站和终端均为测量端，终端向基站发送SRS，基站检测SRS即可得到上行的多个路径的相关信息，基站向终端下发PRS，终端检测PRS即可得到下行的多个路径的相关信息。
步骤120，基于多径参量门限，以及所述多个第一路径的功率参量，从所述多个第一路径中选取至少一个第二路径。
具体地，多径参量门限是与功率参量属于相同参量类型的参量门限，例如功率参量反映相对功率大小时，多径参量门限可以是0-1之间的数值，又例如功率参量反映绝对功率大小时，多径参量门限可以是大于0的数值。多径参量门限的设置，用于从第一路径中筛选第二路径，具体可以是从第一路径中筛选功率参量大于或者等于多径参量门限的路径。基于多径参量门限进行筛选所得的第二路径，其功率本身较高，或者其功率相较于各路径的功率而言较高，第二路径为直射径的概率较高，提供给定位解算端进行定位参考的意义更大。
通过多径参量门限的应用，为选择出首径以外的路径进行信息上报提供了简便易实现的方式，由此选取所得的第二路径，即除首径之外需要进行信息上报的路径，第二路径可以是一条，也可以是多条。
进一步地，多径参量门限可以是测量端自行配置的，也可以是参考信号的发送端配置给测量端的，还可以是位置解算端配置给测量端的。在定位过程中，多径参量门限可以是固定不变的，也可以在终端所处环境、终端自身状态等因素发生变化时触发多径参量门限的重配置，本公开实施例对此不作具体限定。
步骤130，发送所述至少一个第二路径的测量信息。
具体地，测量端在选取得到第二路径之后，即可将第二路径的测量信息发送到位置解算端，使得位置解算端可以根据首径的测量信息，以及各个第二路径的测量信息，对终端进行定位。由于测量端向位置解算端发送的测量信息，均为基于多径参量门限筛选所得第二路径的测量信息，位置解算端在 基于此进行终端定位时，能够得到更多有效的信息，从而保证了终端定位的可靠性和准确性。
本公开实施例提供的方法，基于多径参量门限，以及多个第一路径的功率参量，从多个第一路径中选取第二路径，为位置解算端提供了更多用于定位的有效信息，能够减少定位时噪声和干扰的影响，提升定位性能。
基于上述实施例，步骤120包括：
基于所述多径参量门限、所述多个第一路径的功率参量、多径时间区间和所述多个第一路径的时延，从所述多个第一路径中选取至少一个第二路径；其中，所述多径时间区间是基于所述多径时间区间的长度，以及所述首径的时延确定的。
具体地，在进行第二路径的选取时，不仅需要从能量的角度，结合多径参量门限和各个第一路径的功率参量，对第一路径进行筛选，还需要从时延的角度，结合多径时间区间和各个第一路径的时延，对第一路径进行筛选。
此处，多径时间区间反映的是首径之后，有效多径可能出现的最大时间范围，此处的有效多径即希望通过对第一路径进行筛选后所得的第二路径中包含的路径，是能够为终端定位提供有效信息的路径。结合多径时间区间和各个第一路径的时延，对第一路径进行筛选，具体可以是选取时延处于多径时间区间内的第一路径，由此选取得到的第二路径，其时延处于多径时间区间内，即第二路径有可能是有效多径。
结合能量和时延两个角度对第一路径进行筛选所得的第二路径，即功率参量大于或者等于多径参量门限，且时延处于多径时间区间内的第一路径。
需要说明的是，多径时间区间是基于多径时间区间的长度，以及首径的时延确定的，假设首径的时延为T1，多径时间区间的长度为△T，则多径时间区间可以记为[T1,T1+△T]，其中首径的时延T1是测量端检测得到的，而多径时间区间的长度，即多径时间区间的长度，则可以是测量端自行配置的，也可以是参考信号的发送端配置给测量端的，还可以是位置解算端配置给测量端的。在定位过程中，多径时间区间的长度可以是固定不变的，也可 以在终端所处环境、终端自身状态等因素发生变化时触发多径时间区间的长度的重配置，本公开实施例对此不作具体限定。
本公开实施例提供的方法，基于多径参量门限和多径时间区间，从能量和时延两个角度对第一路径进行筛选，从而为位置解算端提供了更多用于定位的有效信息，减少定位时噪声和干扰的影响，提升定位性能。
基于上述任一实施例，步骤120包括：
从所述多个第一路径中选取至少一个第一候选路径，所述第一候选路径为所述功率参量大于或者等于所述多径参量门限，且所述时延处于所述多径时间区间内的第一路径；
基于所述至少一个第一候选路径的时延和/或功率参量，从所述至少一个第一候选路径中选取至少一个第二路径。
具体地，在全部的第一路径中，同时在能量和时延上满足多径参量门限和多径时间区间的路径数量，可能会超出预先设定好的由测量端发送到定位解算端的第二路径的数量，针对这种情况，需要对同时在能量和时延上满足多径参量门限和多径时间区间的第一路径做进一步的筛选，此处，将同时在能量和时延上满足多径参量门限和多径时间区间的第一路径记为候选第一路径。
在得到全部的候选第一路径之后，即可基于各个候选第一路径的时延和/或功率参量，从候选第一路径中筛选第二路径。例如，可以从全部的候选第一路径中，选取时延最小的预设数量个路径作为第二路径，或者选取功率参量最高的预设数量个路径作为第二路径，再或者在选取功率参量最高的预设数量个路径时，如果存在两个相同功率的候选第一路径时，可以从中选取时延更小的作为第二路径。如果存在两个相同时延的候选第一路径时，可以从中选取功率参量更高的作为第二路径。如果存在两个时延和功率参量均相同的候选第一路径时，可以从中随机选择一个作为第二路径。
本公开实施例提供的方法，应用路径的时延和/或功率，对第一路径进行二次筛选，在为位置解算端提供有效信息的同时，有效限制了信息传输量，避免了传输资源的浪费。
基于上述任一实施例，步骤120中，所述基于所述至少一个第一候选路径的时延和/或功率参量，从所述至少一个第一候选路径中选取至少一个第二路径，包括：
确定按照所述时延从小到大排序时的前第一数量个第一候选路径，作为所述第二路径；
或者，确定按照所述功率参量从大到小排序时的前第二数量个第一候选路径，作为所述第二路径。
具体地，在对第一路径进行二次筛选时，可以按照时延从小到大的顺序，对全部的第一候选路径进行排序，并从排序所得的序列中选取前第一数量个第一候选路径，作为第二路径。由此选择的第二路径，是第一候选路径中时延较小的路径，即选取了时延最小的第一数量个第一候选路径。
此外，也可以按照功率参量从大到小的顺序，对全部的第一候选路径进行排序，并从排序所得的序列中选取前第二数量个第一候选路径，作为第二路径。由此选择的第二路径，是第一候选路径中功率参量较高的路径，即选取了功率参量最高的第二数量个第一候选路径。
需要说明的是，上述第一数量和第二数量均为预先设定好的路径数量，具体反映的是可上报信息的多径数量，第一数量和第二数量可以相等，也可以不等，本公开实施例对此不作具体限定。
基于上述任一实施例，下行定位场景或上下行联合定位场景下，测量端为终端，相应地，上述信息传输方法还包括：
接收定位管理功能单元LMF和/或基站发送的所述功率参量的参量类型、所述多径参量门限或所述多径时间区间的长度中的至少一种；
或者，基于历史信息，或基于所述历史信息和信道变化信息确定所述功率参量的参量类型、所述多径参量门限或所述多径时间区间的长度中的至少一种。
具体地，用于选取第二路径的信息，包括功率参量的参量类型、多径参量门限和多径时间区间的长度，其中功率参量的参量类型决定了具体应用何种功率参量进行第二路径的选取，功率参量的参量类型可以是绝对功率或者 相对功率，也可以是更加细化的第一路径的功率与所有路径的功率最大值之比，或者第一路径的功率与所有路径的功率总和之比等。多径参量门限决定了从能量的角度选取第二路径的门限，多径时间区间的长度决定了从时延的角度选取第二路径的范围，功率参量的参量类型、多径参量门限和多径时间区间的长度可以统一配置，也可以分别配置，还可以选择其中的任意一种或者两种进行配置。
针对测量端为终端的情况，功率参量的参量类型、多径参量门限和多径时间区间的长度可以是由位置解算端和/或基站配置的，此处位置解算端具体为定位管理功能单元(Location Management Function，LMF)。具体可以接收LMF和/或基站发送的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，LMF和/或基站发送上述信息的时机，可以是在定位之前进行预配置，也可以是在定位过程中进行重配置，本公开实施例对此不作具体限定。
例如，LMF可以为终端配置用于定位测量量的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，并基于LTE定位协议(LTE Positioning Protocol，LPP)信令，将功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种发送到终端，从而实现功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的预配置或者重配置。此处的定位测量量可以是下行链路参考信号时间差(DL-RSTD)或者终端RX-TX时间差(UE Rx-Tx time difference)等。
又例如，基站可以基于无线资源控制(Radio Resource Control，RRC)信令，或者基于物理层信令，将功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种发送到终端，从而实现功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的预配置或者重配置。
此外，针对测量端为终端的情况，功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种可以是由终端自行确定的。
进一步地，在由终端预配置功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种时，终端可以基于历史信息实现，此处的历史 信息，可以包括在此之前检测所得首径的信息，即历史首径的信息，例如历史首径的信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)，历史首径的参考信号接收功率(Reference Signal Receiving Power，RSRP)，此处历史首径的SINR和RSRP均可以通过功率时延谱(Power Delay Spectrum，PDP)取窗得到；此外历史信息还可以包括在此之前检测所得终端的移动信息，例如终端的移动速度。例如，终端可以基于历史首径的信息，进行多径参量门限的配置，又例如，终端可以基于历史上的移动信息，进行多径时间区间的长度的配置。
而终端重配置功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，通常发生在信道变化的情况下，此时终端可以结合历史信息和信道变化信息，实现功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的重配置，例如针对由于终端场景变化引起的信道变化，例如终端从室内转移到户外，可以缩短多径时间区间的长度，又例如针对由终端速度变化引起的信道变化，例如终端换乘交通工具突然加速，可以延长多径时间区间的长度。
基于上述任一实施例，在测量端为终端，功率参量的参量类型、多径参量门限和多径时间区间的长度由位置解算端和/或基站配置的情况，该方法还包括：
生成信道变化信息；
将所述信道变化信息发送至所述LMF和/或基站，以触发所述LMF和/或基站重配置所述功率参量的参量类型、所述多径参量门限或所述多径时间区间的长度中的至少一种。
具体地，终端自身所处环境、终端自身状态等因素的变化，均会引发信道变化。终端可以实时监测自身所处环境、终端自身状态等因素是否发生变化，或者信道是否发生变化，如果发生变化，则生成指示变化情况的信道变化信息，并将信道变化信息发送至LMF和/或基站，从而告知LMF和/或基站终端的信道变化情况。LMF和/或基站在接收到信道变化信息后，会触发功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的重 配置，LMF和/或基站可以结合历史信息和信道变化信息，生成新的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，并将新生成的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种发送至终端，从而实现基于信道变化的重配置。
本公开实施例提供的方法，基于信道变化信息对功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种进行重配置，使得用于第二路径选取的参数能够动态满足测量端的实际情况，有助于保证第二路径选取的可靠性。
基于上述任一实施例，上行定位场景或上下行联合定位场景下，测量端为基站，相应地，上述信息传输方法还包括：
接收定位管理功能单元LMF和/或终端发送的所述功率参量的参量类型、所述多径参量门限或所述多径时间区间的长度中的至少一种；
或者，基于历史信息，或基于所述历史信息和信道变化信息确定所述功率参量的参量类型、所述多径参量门限或所述多径时间区间的长度中的至少一种。
具体地，用于选取第二路径的信息，包括功率参量的参量类型、多径参量门限和多径时间区间的长度，其中功率参量的参量类型决定了具体应用何种功率参量进行第二路径的选取，功率参量的参量类型可以是绝对功率或者相对功率，也可以是更加细化的第一路径的功率与所有路径的功率最大值之比，或者第一路径的功率与所有路径的功率总和之比等。多径参量门限决定了从能量的角度选取第二路径的门限，多径时间区间的长度决定了从时延的角度选取第二路径的范围，功率参量的参量类型、多径参量门限和多径时间区间的长度可以统一配置，也可以分别配置，还可以选择其中的任意一种或者两种进行配置。
针对测量端为基站的情况，功率参量的参量类型、多径参量门限和多径时间区间的长度可以是由位置解算端和/或终端配置的，此处位置解算端具体为定位管理功能单元LMF。具体可以接收LMF和/或终端发送的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，LMF和/ 或终端发送上述信息的时机，可以是在定位之前进行预配置，也可以是在定位过程中进行重配置，本公开实施例对此不作具体限定。
例如，LMF可以为基站配置用于定位测量量的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，并基于NR定位协议A(NR Positioning Protocol A，NRPPa)信令，将功率参量的参量类型、多径参量门限和多径时间区间的长度中的至少一种发送到基站，从而实现功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的预配置或者重配置。此处的定位测量量可以是上行链路相对到达时间(UL relative time of arrival，UL-RTOA)或者gNB RX-TX时间差(gNB Rx-Tx time difference)等。
又例如，终端可以基于RRC信令，或者基于物理层信令，将功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种发送到基站，从而实现功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的预配置或者重配置。
此外，针对测量端为基站的情况，功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种可以是由基站自行确定的。
进一步地，在由基站预配置功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种时，基站可以基于历史信息实现，此处的历史信息，可以包括在此之前检测所得首径的信息，即历史首径的信息，例如历史首径的SINR，历史首径的RSRP，此外历史信息还可以包括在此之前检测所得终端的移动信息，例如终端的移动速度。例如，基站可以基于历史首径的信息，进行多径参量门限的配置，又例如，基站可以基于历史上的移动信息，进行多径时间区间的长度的配置。
而基站重配置功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，通常发生在信道变化的情况下，此时基站可以结合历史信息和信道变化信息，实现功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的重配置，例如针对由于终端场景变化引起的信道变化，例如终端从室内转移到户外，可以缩短多径时间区间的长度，又例如针 对由终端速度变化引起的信道变化，例如终端换乘交通工具突然加速，可以延长多径时间区间的长度。
基于上述任一实施例，在测量端为基站，功率参量的参量类型、多径参量门限和多径时间区间的长度由位置解算端配置的情况，该方法还包括：
接收所述终端生成的信道变化信息，或生成信道变化信息；
将所述信道变化信息发送至所述LMF，以触发所述LMF重配置所述功率参量的参量类型、所述多径参量门限或所述多径时间区间的长度中的至少一种。
具体地，对于基站而言，终端的信道变化信息，可以是基站自行检测并生成的，也可以是终端检测生成后发送到基站的。例如，基站可以自行生成信道变化信息，并将信道变化信息发送至LMF，又例如，终端可以生成信道变化信息并发送至基站，基站在接收到信道变化信息之后，可以将信道变化信息转发到LMF，从而告知LMF终端的信道变化情况。LMF在接收到信道变化信息后，会触发功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的重配置，LMF可以结合历史信息和信道变化信息，生成新的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，并将新生成的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种发送至基站，从而实现基于信道变化的重配置。
本公开实施例提供的方法，基于信道变化信息对功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种进行重配置，使得用于第二路径选取的参数能够动态满足测量端的实际情况，有助于保证第二路径选取的可靠性。
基于上述任一实施例，所述功率参量的参量类型为绝对功率或相对功率中的任意一种。
图2是本公开提供的路径选择示意图，图2中的坐标系下，横坐标表示时延Delay，纵坐标表示功率Power，Path_1为首径，Path_1在横坐标上的位置即首径的时延T1，Path_1在纵坐标方向上的取值P_first_path即首径的功率。 假设任意第一路径为Path_i，Path_i在纵坐标方向上的取值P_i_path即该条第一路径的功率，此外图中示出的P_max_path表示所有路径的功率最大值。
由此，功率参量的参量类型可以表示为如下四种形式中的任意一种：
第一路径的功率与所有路径的功率最大值之比，可以表示为：
P_i_path/P_max_path；
第一路径的功率与所有路径的功率总和之比，可以表示为：
P_i_path/P_total_path，其中P_total_path即所有路径的功率总和；
第一路径的功率与首径的功率之比，可以表示为：
P_i_path/P_first_path；
第一路径的功率，即第一路径的绝对功率值，可以表示为：
P_i_path。
其中，前三种参量类型均反映相对功率大小，最后一种参量类型则反映绝对功率大小。前三种参量类型对应的多径参量门限的取值在0-1之间，最后一种参量类型对应的多径参量门限的取值大于0。
此外，图2中还标记有多径时间区间的长度为△T，配合首径的时延T1，可以在横坐标上定位多径时间区间[T1,T1+△T]，由此得到时延处于多径时间区间内的第一路径。在此基础上，图2中还标记了多径参量门限Threshold_T，图2中功率超过基于Threshold_T确定的点划线，且时延处于多径时间区间[T1,T1+△T]内的第一路径，均可能被选中作为第二路径。
基于上述任一实施例，所述测量端为终端时，所述第二路径的测量信息包括所述第二路径的功率参量、到达时间、收发时间差或相位中的至少一种；或者，
所述测量端为基站时，所述第二路径的测量信息包括所述第二路径的功率参量、到达时间、收发时间差、到达角度或相位中的至少一种。
具体地，测量端可以通过PDP取窗滤出各径，重新生成信道冲激响应(Channel Impulse Response，CIR)或信道频率响应(Channel Frequency Response，CFR)，从而得到各径在特定子载波上的相位。
进一步地，多径的角度和相位可以通过如下步骤获得：
1、对PDP谱取窗，窗口长度只包含目标径(包括其能量弥散)，图3是本公开提供的角度、相位获取方法示意图，如图3所示；需要说明的是，此处的目标径即任一第二路径，图3中的PDP window for path_i即path_i的PDP窗；
2、根据时延重新生成CIR/CFR；
3、计算特定子载波上的相位信息，或进行到达角度测距(Angle-of-Arrival，AOA)估计得到角度。
此外，本公开还提供一种信息传输方法，应用于定位场景下的位置解算端，例如可以是LMF。图4是本公开提供的信息传输方法的流程示意图之二，如图4所示，该方法包括：
步骤410，接收测量端发送的至少一个第二路径的测量信息，所述至少一个第二路径是所述测量端基于多径参量门限，以及多个第一路径的功率参量，从所述多个第一路径中选取的，所述多个第一路径为所述测量端检测参考信号所得的除首径以外的其他路径。
具体地，在进行定位时，测量端可以通过检测参考信号得到多个路径，此处的所指的多个路径包括首径和第一路径，其中，首径即测量端检测参考信号得到的多个路径中的首径，首径具体是多个路径中最早被测量端检测到的路径，多个路径中，除首径之外的其他路径均可记为第一路径。
针对各个第一路径，测量端均可检测得到该第一路径的功率参量，此处的功率参量用于反映第一路径的功率大小，具体可以反映第一路径的相对功率大小，此时功率参量可以是第一路径的功率和参考功率的比值，例如第一路径的功率与首径的功率的比值，又例如第一路径的功率和所有路径的功率之和的比值；功率参量也可以反映第一路径的绝对功率大小，此时功率参量可以是第一路径的绝对功率值。
需要说明的是，上行定位场景中，测量端为基站，参考信号即SRS，终端向基站发送SRS，基站检测SRS即可得到多个路径的相关信息。下行定位场景中，测量端为终端，参考信号即PRS。基站向终端下发PRS，终端检测PRS即可得到多个路径的相关信息。上下行联合定位场景中，基站和终端均 为测量端，终端向基站发送SRS，基站检测SRS即可得到上行的多个路径的相关信息，基站向终端下发PRS，终端检测PRS即可得到下行的多个路径的相关信息。
测量端在检测得到多个第一路径的功率参量之后，即可应用各个第一路径的功率参量，以及配置好的多径参量门限，从第一路径中筛选第二路径，进而将第二路径的测量信息发送到位置解算端。
此处，多径参量门限是与功率参量属于相同参量类型的参量门限，例如功率参量反映相对功率大小时，多径参量门限可以是0-1之间的数值，又例如功率参量反映绝对功率大小时，多径参量门限可以是大于0的数值。多径参量门限的设置，使得测量端能够从第一路径中筛选第二路径，具体可以是从第一路径中筛选功率参量大于或者等于多径参量门限的路径。基于多径参量门限进行筛选所得的第二路径，其功率本身较高，或者其功率相较于各路径的功率而言较高，第二路径为直射径的概率较高，提供给定位解算端进行定位参考的意义更大。
通过多径参量门限的应用，为测量端选择出首径以外的路径进行信息上报提供了简便易实现的方式，由此选取所得的第二路径，即除首径之外需要进行信息上报的路径，第二路径可以是一条，也可以是多条。
进一步地，多径参量门限可以是测量端自行配置的，也可以是参考信号的发送端配置给测量端的，还可以是位置解算端配置给测量端的。在定位过程中，多径参量门限可以是固定不变的，也可以在终端所处环境、终端自身状态等因素发生变化时触发多径参量门限的重配置，本公开实施例对此不作具体限定。
相应地，位置解算端可以接收到测量端发送的至少一个第二路径的测量信息。
步骤420，基于所述至少一个第二路径的测量信息，对终端进行定位。
具体地，在接收到至少一个第二路径的测量信息之后，位置解算端即可基于此进行终端定位。而由于测量端向位置解算端发送的测量信息，均为基于多径参量门限筛选所得第二路径的测量信息，位置解算端在基于此进行终 端定位时，能够得到更多有效的信息，从而保证了终端定位的可靠性和准确性。
进一步地，位置解算端在进行终端定位时，可以将接收到的首径的测量信息以及至少一个第二路径的测量信息，输入到预先训练好的位置解算模型中，从而获取位置解算模型输出的定位结果，此处的位置解算模型可以是基于卷积神经网络(Convolutional Neural Networks，CNN)或者深度神经网络(Deep Neural Networks，DNN)等神经网络架构构建的，也可以基于接收到的首径的测量信息以及至少一个第二路径的测量信息进行NLOS判断，并基于判断结果进行位置解算，还可以应用接收到的首径的测量信息以及至少一个第二路径的测量信息，在指纹数据库中进行指纹匹配，从而实现位置解算，本公开实施例不对此作具体限定。
本公开实施例提供的方法，测量端基于多径参量门限，以及多个第一路径的功率参量，从多个第一路径中选取第二路径，使得位置解算端能够得到更多用于定位的有效信息，减少了定位时噪声和干扰的影响，提升了定位性能。
基于上述实施例，该方法还包括：
基于历史信息，确定所述功率参量的参量类型、所述多径参量门限或多径时间区间的长度中的至少一种；
向所述测量端发送所述功率参量的参量类型、所述多径参量门限或所述多径时间区间的长度中的至少一种。
具体地，测量端用于选取第二路径的信息，包括功率参量的参量类型、多径参量门限和多径时间区间的长度，其中功率参量的参量类型决定了具体应用何种功率参量进行第二路径的选取，功率参量的参量类型可以是绝对功率或者相对功率，也可以是更加细化的第一路径的功率与所有路径的功率最大值之比，或者第一路径的功率与所有路径的功率总和之比等。多径参量门限决定了从能量的角度选取第二路径的门限，多径时间区间的长度决定了从时延的角度选取第二路径的范围，功率参量的参量类型、多径参量门限和多径时间区间的长度可以由位置解算端统一配置，也可以由位置解算端分别配 置，还可以由位置解算端选择其中的任意一种或者两种进行配置。此处所指的配置，可以是在定位之前进行预配置，也可以是在定位过程中进行重配置，本公开实施例对此不作具体限定。
位置解算端在向测量端发送功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种之前，需要先确定功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的取值。位置解算端在确定功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种时，可以基于历史信息实现。此处的历史信息，可以包括在此之前接收到的首径的信息，即历史首径的信息，例如历史首径SINR，历史首径的RSRP，此外历史信息还可以包括在此之前接收到的终端的移动信息，例如终端的移动速度。例如，位置解算端可以基于历史首径的信息，进行多径参量门限的配置，又例如，位置解算端可以基于历史上的移动信息，进行多径时间区间的长度的配置。
以位置解算端为LMF为例，针对测量端为终端的情况，LMF可以通过LPP信令，将功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种发送到终端，从而实现功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的预配置或者重配置。
针对测量端为基站的情况，LMF可以基于NRPPa信令，将功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种发送到基站，从而实现功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的预配置或者重配置。
基于上述任一实施例，所述确定所述功率参量的参量类型、所述多径参量门限或多径时间区间的长度中的至少一种，包括：
接收所述终端和/或基站发送的信道变化信息，基于所述历史信息和所述信道变化信息重配置所述功率参量的参量类型、所述多径参量门限或多径时间区间的长度中的至少一种。
具体地，终端自身所处环境、终端自身状态等因素的变化，均会引发信道变化。终端可以实时监测自身所处环境、终端自身状态等因素是否发生变 化，或者信道是否发生变化，如果发生变化，则生成指示变化情况的信道变化信息，并将信道变化信息发送至位置解算端，从而告知位置解算端终端的信道变化情况。此外，终端还可以生成指示变化情况的信道变化信息，并将信道变化信息发送至基站，基站在接收到信道变化信息之后，可以将信道变化信息再转发到位置解算端，从而告知位置解算端终端的信道变化情况。
位置解算端在接收到信道变化信息后，会触发功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种的重配置，生成新的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种，并将新生成的功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种发送至测量端，从而实现基于信道变化的重配置。
位置解算端在进行重配置时，可以结合历史信息和信道变化信息执行，例如针对由于终端场景变化引起的信道变化，例如终端从室内转移到户外，位置解算端可以缩短多径时间区间的长度，又例如针对由终端速度变化引起的信道变化，例如终端换乘交通工具突然加速，位置解算端可以延长多径时间区间的长度。
本公开实施例提供的方法，基于信道变化信息对功率参量的参量类型、多径参量门限或多径时间区间的长度中的至少一种进行重配置，使得用于第二路径选取的参数能够动态满足测量端的实际情况，有助于保证第二路径选取的可靠性。

第一路径的功率与首径的功率之比，可以表示为：

其中，前三种参量类型均反映相对功率大小，最后一种参量类型则反映绝对功率大小。前三种参量类型对应的多径参量门限的取值在0-1之间，最后一种参量类型对应的多径参量门限的取值大于0。
