具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在高频场景中，符号间CP变短，在不进行多个测量节点的时间提前量(Time Advance，TA)估计的情况下，会出现目标节点的上行定位参考信号和相邻测量节点中其它目标节点的信号达到该目标节点所在的测量节点的符号偏移超过CP长度的情况下，从而对定位性能造成影响，对相邻测量节点中目标节点的通信造成干扰。图1是一种通信场景示意图。如图1所示，在一个通信***中有两个测量节点，分别为测量节点A和测量节点B，目标节点1所属的服务基站为测量节点A，若不对测量节点A和测量节点B的TA进行估计，并且在高频场景下，目标节点1的上行定位参考信号到达相邻的测量节点B的符号偏移会超过CP长度，从而对目标节点1的定位造成影响，对相邻的测量节点B中目标节点2的通信造成干扰。
在本申请实施例中，提供一种上行定位的实现方法，避免对目标节点的定 位造成影响，从而实现对目标节点的准确定位，以及降低对相邻测量节点中终端的通信干扰。在实施例中，测量节点为基站，目标节点为用户终端，定位服务器为核心网。
在一实施例中，图2是实施例提供的一种上行定位的实现方法的流程图。该方法由定位服务器执行，以用于实现对多个测量节点的TA进行估计。如图2所示，本实施例提供的方法包括步骤101-步骤103：
步骤101、向第一测量节点集合发送第一定位指令。
第一测量节点集合包括至少三个测量节点，目标节点位于测量节点的覆盖范围内。
步骤102、接收每个测量节点反馈的与第一定位指令对应的第一定位属性信息。
第一定位属性信息包括：测量节点标识和测量节点所在小区的随机接入信息。
步骤103、将携带第一定位属性信息的随机接入指令发送至目标节点。
随机接入指令用于触发目标节点向测量节点发送随机接入信号，以确定目标节点与每个测量节点之间的通信距离。
在实施例中，在目标节点需要定位的情况下，比如，在目标节点向定位服务器发送上行定位请求，或者在需要通过定位服务器对目标节点进行定位的情况下，定位服务器向第一测量节点集合发送第一定位指令。其中，第一测量节点集合中包括至少三个测量节点，并且，目标节点位于多个测量节点的覆盖范围内，即第一测量节点集合中的所有测量节点的通信范围可以覆盖到目标节点。第一定位指令为上报每个测量节点标识和每个测量节点所在服务小区的随机接入信息的指令。在第一测量节点集合中的每个测量节点接收到第一定位指令，每个测量节点将自身的测量节点标识和所在服务小区的随机接入信息上报至定位服务器。在定位服务器接收到每个测量节点反馈的自身测量节点标识和所在小区的随机接入信息之后，定位服务器给目标节点下发随机接入指令，以使目标节点接收到随机接入指令之后，识别每个测量节点的标识和所在小区的随机接入信息，以向对应的测量节点发射随机接入信号。其中，随机接入信息包括物理随机接入信道(Physical Random Access Channel，PRACH)的信道资源分配信息和所支持的前导(Preamble)信息。其中，Preamble信息为Preamble码，共有64位，是用户设备在PRACH中发送的实际内容，由长度为Tcp的循环前缀CP和长度为Tseq的序列(Sequence)组成。
在目标节点向第一测量节点集合中的每个测量节点发射随机接入信号之 后，通过每个测量节点接收到随机接入信号的时间，可计算得到目标节点到每个测量节点之间的通信距离，进而可实现对目标节点的定位。在确定目标节点到每个测量节点的通信距离之后，可根据每个通信距离调整目标节点向对应测量节点发射信号的发射时间，以保证目标节点发送信号至每个测量节点的到达时间是相同的，以避免对相邻测量节点中其它目标节点的通信干扰。
在一实施例中，在第一测量节点集合中的一个测量节点为服务节点的情况下，步骤103包括步骤1031-步骤1032：
步骤1031、将第一定位属性信息发送至服务节点。
服务节点为目标节点当前已建立通信的基站小区。
步骤1032、通过服务节点将携带第一定位属性信息的下行控制信息DCI发送至目标节点。
在实施例中，在第一测量节点集合中的一个测量节点为服务节点的情况下，定义服务器可将第一测量节点集合中每个测量节点标识和测量节点所在小区的随机接入信息发送至服务节点，通过服务节点将每个测量节点标识和每个测量节点所在小区的随机接入信息发送至目标节点。一个实施例中，在服务节点接收到每个测量节点标识和每个测量节点所在小区的随机接入信息之后，服务节点会配置至少两个下行控制信息(Downlink Control Information，DCI)，并将DCI下发至目标节点，通过DCI信息触发目标节点向每个测量节点发射随机接入信号，以确定目标节点到每个测量节点的通信距离。其中，下行控制信息的个数与测量节点的个数是相同的，即每个下行控制信息对应一个测量节点的第一定位属性信息。
在一实施例中，图3是实施例提供的另一种上行定位的实现方法的流程图。该方法由测量节点执行，以用于实现对多个测量节点的TA进行估计。如图3所示，本实施例提供的方法包括步骤201-步骤203：

步骤203、将第一定位属性信息反馈至定位服务器。
第一定位属性信息为目标节点所要建立通信的多个测量节点的属性信息，第一定位属性信息包括：测量节点标识和测量节点所在小区的随机接入信息。
在实施例中，在第一测量节点集合中的每个测量节点接收到定位服务器发 送的第一定位指令后，每个测量节点从预设数据库中识别提取自身的测量节点标识和所在小区的随机接入信息，并发送至定位服务器，以通过定位服务器将测量节点标识和所在小区的随机接入信息转发至目标节点，从而使目标节点向每个测量节点发射随机接入信号。
在一实施例中，图4是实施例提供的一种上行定位的实现方法的交互示意图。本实施例提供的方法适用于直接通过定位服务器将随机接入指令发送至目标节点的场景下，对多个测量节点的TA进行估计。如图4所示，该方法包括步骤301-步骤304：
步骤301、发送第一定位指令。
步骤302、接收第一定位属性信息。
步骤303、将随机接入指令发送至目标节点。
步骤304、发射随机接入信号。
在实施例中，定位服务器给第一测量节点集合中的每个测量节点发送第一定位指令，每个测量节点在接收到第一定位指令之后，上报自身的测量节点标识和所在小区的随机接入信息至定位服务器；在定位服务器接收到每个测量节点标识和每个测量节点所在小区的随机接入信息之后，定位服务器给目标节点下发随机接入指令，在目标节点接收到随机接入指令之后，通过每个测量节点标识和每个测量节点所在小区的随机接入信息，向每个测量节点发射随机接入信号。其中，随机接入指令为定位测量激活指令，即触发每个测量节点开始接收目标节点发送的随机接入信号。
在一实施例中，图5是实施例提供的另一种上行定位的实现方法的交互示意图。本实施例提供的方法适用于通过服务节点将随机接入指令发送至目标节点的场景下，对多个测量节点的TA进行估计。
在实施例中，第一测量节点集合中的一个测量节点为服务节点。如图5所示，该方法包括步骤401-步骤405：
步骤401、发送第一定位指令。
步骤402、上报第一定位属性信息。
步骤403、发送第一定位属性信息。
步骤404、发送DCI。
步骤405、发射随机接入信号。
在实施例中，在通过服务节点将携带第一定位属性信息的DCI发送至目标节点的情况下，服务节点可将自身的节点标识和所在小区的随机接入信息发送 至定位服务器，以将服务节点的节点标识和所在小区的随机接入信息存储至定位服务器，以便于后续调取使用或查询。在服务节点将第一测量节点集合中的每个测量节点标识和每个测量节点所在小区的随机接入信息发送至目标节点时，也需将服务节点的自身节点标识和所在小区的随机接入信息发送至目标节点，从而目标节点可向服务节点和每个测量节点发射随机接入信号。
一个实施例中，图6是实施例提供的又一种上行定位的实现方法的流程图。该方法由服务节点执行，以用于实现对多个测量节点的TA进行估计。如图6所示，本实施例提供的方法包括步骤501-步骤504：
步骤501、接收定位服务器发送的第二定位指令。
步骤502、将根据第二定位指令确定的第二测量节点集合反馈至定位服务器。
第二测量节点集合包括除服务节点之外的至少两个测量节点，目标节点位于测量节点的覆盖范围内，服务节点提供的一个服务小区已与目标节点建立通信连接。
步骤503、接收每个测量节点反馈的第二定位属性信息。
第二定位属性信息包括：测量节点标识和测量节点所在小区的随机接入信息。
步骤504、将携带第二定位属性信息的DCI发送至目标节点。
DCI用于触发目标节点向测量节点发送随机接入信号，以确定目标节点与每个测量节点之间的通信距离。
在实施例中，在所采用的用于目标节点定位的至少两个测量节点，是通过服务节点进行选择的。在需对目标节点进行上行定位的情况下，定位服务器向服务节点发送第二定位指令，服务节点根据第二定位指令选择所使用的至少两个测量节点，并将每个测量节点上报给定位服务器，以使定位服务器给每个测量节点下发第一定位激活指令，以触发每个测量节点将自身的第二定位属性信息发送至服务节点。其中，第一定位激活指令用于触发每个测量节点将第二定位属性信息反馈至服务节点。在服务节点接收到每个测量节点的第二定位属性信息之后，对第二定位属性信息进行配置，以得到至少两个DCI。将每个DCI下发至目标节点，以触发目标节点向服务节点和每个测量节点发射随机接入信号，以确定目标节点与每个测量节点之间的通信距离。其中，为了便于目标节点根据DCI识别得到对应的每个测量节点标识和每个测量节点所在小区的随机接入信号，可在DCI和测量节点标识之间设置一一对应关系，即每个测量节点标识对应一个DCI。
一个实施例中，图7是实施例提供的再一种上行定位的实现方法的流程图。该方法由定位服务器执行，以用于实现对多个测量节点的TA进行估计。如图7所示，本实施例提供的方法包括步骤601-步骤603：
步骤601、向服务节点发送第二定位指令。
服务节点提供的一个服务小区已与目标节点建立通信连接。
步骤602、接收服务节点反馈的第二测量节点集合。
第二测量节点集合是根据第二定位指令而确定的，第二测量节点集合包括除服务节点之外的至少两个测量节点，目标节点位于测量节点的覆盖范围内。
步骤603、向每个测量节点发送携带服务节点标识的第一定位激活指令。
第一定位激活指令用于触发每个测量节点将第二定位属性信息发送至服务节点，第二定位属性信息为目标节点所要建立通信的多个测量节点的属性信息，第二定位属性信息包括：测量节点标识和测量节点所在小区的随机接入信息。
在实施例中，为了便于每个测量节点能够将自身的第二定位属性信息发送至服务节点，在定位服务器给每个测量节点下发第一定位激活指令时，也会将服务节点标识下发至每个测量节点。

一个实施例中，图9是实施例提供的又一种上行定位的实现方法的交互示意图。该实施例以在目标节点、服务节点、定位服务器、测量节点之间的交互通信，对上行定位的实现方法进行说明。如图9所示，该实施例中的方法包括步骤801-步骤80:

一个实施例中，在目标节点向服务节点或每个测量节点发送随机接入信号之后，为了保证目标节点向服务节点或每个测量节点发送的上行定位参考信号的发射功率，能够匹配服务节点或对应测量节点的发射波束的功率，需调整目标节点所发送的对应上行定位参考信号的目标发射功率。在所述将携带所述第二定位属性信息的下行控制信息DCI发送至目标节点之后，还包括：接收目标节点发送的根据第一配置信息确定的上行定位参考信号，以及每个上行定位参考信号与对应测量节点的关系，第一配置信息包括：多个空间相关性、多个预设下行定位参考信号和多个第三定位属性信息，空间相关性用于表征每个预设下行定位参考信号与对应上行定位参考信号的相关性，第三定位属性信息包括：路损测量信号类型、路损测量信号标识、路损测量信号时频资源、路损测量信 号发射功率和路损测量信号序列；根据上行定位参考信号的接收强度确定功率调整参数；将功率调整参数返回至目标节点，功率调整参数用于将目标节点发送至对应测量节点的上行定位参考信号的当前发射功率调整至目标发射功率。
在实施例中，目标节点根据每个测量节点的第三定位属性信息进行波束匹配，并结合上行定位参考信号和预设下行定位参考信号的空间相关性，确定对应上行定位参考信号的发射波束和当前发射功率，然后目标节点按照发射波束和当前发射功率，向服务节点发送上行定位参考信号。其中，上行定位参考信号为多个测量节点对应的信号，即为了使得服务节点能够将接收到的功率调整参数与上行定位参考信号以及测量节点进行对应，在目标节点向服务节点发送上行定位参考信号的同时，也需发送每个上行定位参考信号与对应测量节点的关系。在每个测量节点接收到目标节点发送的对应上行定位参考信号之后，每个测量节点根据所接收到的上行定位参考信号的接收强度确定功率调整参数，以使目标节点将发送至对应测量节点的上行定位参考信号的当前发射功率调整至目标发射功率，从而保证目标节点发射上行定位参考信号的发射功率的准确性，既避免了发射功率过大，造成资源浪费，又避免了发射功率过小，造成无法准确地接收到上行定位参考信号。

在一实施例中，图11是实施例提供的再一种上行定位的实现方法的交互示意图。如图11所示，该方法包括：
步骤901、上报RRM测量信息。

步骤931、上报测量结果。
步骤933、计算定位结果。
在实施例中，需要定位的目标节点将RRM测量信息上报给定位服务器，RRM测量信息包括所在服务节点的下行定位参考信号类型、所在小区标识、所在时频域资源的位置。在本实施例中，假设目标节点可以测得基站A、B、C、D四个节点的下行CSI-RS。定位服务器选定基站A、B、C、D为本次定位所使用的测量节点。其中，测量节点A为服务基站，即服务节点。
定位服务器给作为服务基站的测量节点A和所有本次用作定位的测量节点发送第三定位指令，要求每个测量节点上报对应的第三定位属性信息，第三定位属性信息为多个测量节点用于路损测量的信号参数信息，所述第三定位属性信息包括：路损测量信号类型、路损测量信号标识、路损测量信号时频资源、路损测量信号发射功率和路损测量信号序列，还包括测量节点的位置信息。
服务节点和每个测量节点根据第三定位指令上报对应的第三定位属性信息，定位服务器结合目标节点的RRM测量结果和每个测量节点可用的路损测量信号，识别可能被目标节点较好识别的每个测量节点对应的预设下行参考信号。本实施例中，通过RRM测量结果对比得到测量节点A、B、C、D的CSI-RS A，CIS-RS B，CSI-RS C，CSI-RS D，这四个信号既可以用作自身对应测量节点的路损信号测量，同时可以被目标节点检测到用作RRM测量。其中，CSI-RS A对应测量节点A的CIS-RS，CSI-RS B对应测量节点B的CIS-RS，CSI-RS C对应测量节点C的CIS-RS，CSI-RS D对应测量节点D的CIS-RS。
定位服务器给服务节点(测量节点A)发送定位配置指令，即上行定位参考信号配置指令。该指令通知服务节点开始给目标节点配置上行定位参考信号。同时在该指令中指示CSI-RS A，CIS-RS B，CSI-RS C，CSI-RS D是分别来自测量节点A、B、C、D的预设下行参考信号，即理想下行信号。同时给测量节点A、B、C、D发送第二定位激活指令，用于指示测量节点A、B、C、D开始测量目标节点的上行定位参考信号。测量节点A、B、C、D测量来自目标节点的上行定位参考信号并将测量结果上报给定位服务器，由定位服务器进行位置计算。
服务节点(测量节点A)给目标节点配置测量节点A、B、C、D的下行定位参考信号资源分别为资源1，资源2，资源3，资源4。资源1的下行路损测量信号为CSI-RS A，资源2的下行路损测量信号为CIS-RS B，资源3的下行路损测量信号为CSI-RS C，资源4的下行路损测量信号为CSI-RS D，且资源1与信号CSI-RS A有空间相关性，资源2与信号CIS-RS B有空间相关性，资源3与信号CSI-RS C有空间相关性，资源4与信号CSI-RS D有空间相关性。将包含多个空间相关性、多个预设下行定位参考信号和多个第三定位属性信息的第一配置信息发送给目标节点。
在所使用的路损测量信号与目标节点进行RRM测量的信号之间有一一对应关系，则该目标节点已知多个下行定位参考信号的最佳接收波束。由于每个上行定位参考信号对应的上行信号资源和自身对应的CSI-RS存在空间相关性，目标节点可以知道每个上行信号资源的最佳发射波束以指向对应的测量节点。目标节点发射上行定位参考信号至对应的测量节点，同时上报对应测量节点和CSI-RS的对应关系。
每个测量节点测量对目标节点发射的上行定位参考信号进行测量，根据接收强度的大小配置功率调整参数，其中，服务节点(测量节点A)的相邻测量节点(测量节点B、C、D)将该功率调整参数发送给服务节点。
服务节点根据自身测量对资源1进行功率控制参数配置，同时将接收到测量节点B的功率控制参数配置给资源2，将来自测量节点C的功率控制参数配 置给资源3，将来自测量节点D的功率控制参数配置给资源4，并将资源调整参数发送给目标节点。
目标节点根据接收到的功率调整参数调整资源1、2、3、4分别对应的发射功率，以调整至目标发射功率。
在一实施例中，图12是实施例提供的还一种上行定位的实现方法的交互示意图。如图12所示，该方法包括：

步骤1011、发送第二定位激活指令。
步骤1013、配置上行定位参考信号，并根据预设下行定位参考信号确定对应上行信号资源的空间相关性。
步骤1015、发送第一配置信息。
步骤1017、确定上行定位参考信号的发射波束和当前发射功率。
步骤1019、发送上行定位参考信号，以及每个上行定位参考信号与测量节点的对应关系。
步骤1021、对上行定位参考信号进行测量，确定功率调整参数。
步骤1023、将功率调整参数发送至服务节点。
步骤1025、将功率调整参数发送至目标节点。
步骤1027、按照功率调整参数将上行定位参考信号的发射功率调整至目标发射功率。
步骤1029、按照目标发射功率发射上行定位参考信号。
步骤1031、上报测量结果。
步骤1033、计算定位结果。
对上述步骤1001-步骤1033进行解释，如下：步骤1001-步骤1033分别与步骤901-步骤933一一对应。区别是：目标节点在上报RRM测量信息时，可直接将RRM测量信息上报至服务节点，并且，在每个测量节点上报第三定位属性信息时，可直接上报至服务节点，避免了第三定位属性信息在定位服务器的中 转，降低了传输时延。在直接将第三定位属性信息发送至服务节点的情况下，每个测量节点的预设下行定位参考信号可通过服务节点进行确定。对步骤1001-步骤1033的解释说明见上述实施例的步骤901-步骤933的描述，在此不再赘述。
在一实施例中，图13是实施例提供的还一种上行定位的实现方法的交互示意图。如图13所示，该方法包括：

步骤1129、按照目标发射功率发射上行定位参考信号。
步骤1131、上报测量结果。
步骤1133、计算定位结果。
对上述步骤1101-步骤1133进行解释，如下：步骤1101-步骤1133分别与步骤901-步骤933一一对应。区别是：在目标节点上报RRM测量信息之后，增加步骤1102，以实现对多个测量节点的TA估计。其中，对多个测量节点的TA估计的实现方式见上述实施例中确定目标节点到每个测量节点的通信距离的方 案，在此不再赘述。在确定每个测量节点的TA值之后，通过服务节点将每个测量节点的TA值发送给目标节点，从而在目标节点发射上行定位参考信号的过程中，对每个上行信号资源使用对应的TA值进行发送，即步骤1119发射上行定位参考信号的步骤，采用每个测量节点的上行信号资源对应的TA值对上行定位参考信号进行发送。
在一实施例中，只对服务节点进行发射功率控制。在服务节点接收到定位服务器的定位激活指令之后，服务节点选择所使用的测量节点，发送给定位服务器。服务节点配置目标节点使用的上行定位参考信号对应的上行信号资源，指定与自身对应的上行定位参考信号的上行信号资源，确定上行信号资源的初始发射功率和路损测量信号信息。目标节点对服务节点的路损测量信号进行测量，并进行波束匹配，确定发送给服务节点的上行定位参考信号对应的上行信号资源的发射功率和发射方向，而发射给其它测量节点的上行定位参考信号对应的上行信号资源的发射功率是满功率发送。在服务节点接收到目标节点的上行定位参考信号之后，对该上行定位参考信号对应的上行信号资源进行发射功率控制。
