具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也是旨在包括多数形式，除非上下文清楚地表示其它含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地， 第二信息也可以被称为第一信息。取决于语境，例如，在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
下面，对本公开的应用场景进行说明：
图1示出了本公开一个示例性实施例提供的通信系统的框图，该通信系统可以包括：终端10、接入网设备20和位置服务器30。
终端10的数量通常为多个，每一个网络设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
接入网设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为接入网设备。接入网设备20与终端10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备20的数量可以有多个，两个邻近的接入网设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的接入网设备20之间进行切换，也即与不同的接入网设备20建立连接。
位置服务器30是一种位置管理功能网元。可选地，位置管理功能网元包括位置服务器(location server)，位置服务器可以实现为以下任意一项：LMF(Location Management Function，位置管理网元)、E-SMLC(Enhanced Serving Mobile Location Centre，增强服务的流动定位中心)、SUPL(Secure User Plane Location，安全用户平面定位)、SUPL SLP(SUPL Location Platform，安全用户平面定位定位平台)。在无线接入技术的系统中，该位置服务器与终端10和接入网设备20之间分别连接，进而可以分别与终端10和接入网设备20进行通信。该位置服务器可以对终端10进行定位，进而获取终端10的定位位置。其中，位置服务器30通过发送PRS(Positioning Reference Signal，定位参考信号)或SRS(Sounding Reference Signal，探测参考信号)的配置信息，来对终端10进行定位。其中，PRS由至少一个TRP(Transmission Reception Point，发送接收 点)发送，终端对PRS进行测量。SRS由终端发送，至少一个TRP对SRS进行测量。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
图2示出了本公开一个示例性实施例提供的信息配置方法的流程图，应用于如图1所示的终端、接入网设备和位置服务器中，该方法包括以下内容中的至少部分内容：
步骤201：终端接收第一配置信息，第一配置信息指示定位参考信号的优先级为目标优先级，目标优先级的定位参考信号为终端无需基于测量间隔进行测量的定位参考信号。
在本申请实施例中，终端接收到第一配置信息，即可确定优先级为目标优先级的定位参考信号，并且基于该目标优先级，确定无需基于测量间隔即可对这些定位参考信号进行测量。
在一些实施例中，定位参考信号对应的优先级为目标优先级。
例如，定位参考信号的优先级由0或1表示，若定位参考信号的优先级为0，则说明不是目标优先级，若定位参考信号的优先级为1，则说明是目标优先级。
在另一些实施例中，定位参考信号对应有优先级，若定位参考信号的优先级小于预设门限，确定定位参考信号对应的优先级为目标优先级。
其中，该预设门限由终端设置，或者由接入网设备或位置服务器设置，或者由协议约定，或者采用其他方式设置，本申请实施例不作限定。该预设门限为1、2、3或者其他数值。
例如，若预设门限为5，定位参考信号对应的优先级为3时，确定定位参考信号对应的优先级为目标优先级，而定位参考信号对应的优先级为6时，确定定位参考信号对应的优先级为非目标优先级。
步骤202：终端根据第一配置信息，对定位参考信号进行测量。
在本申请实施例中，终端确定第一配置信息指示的目标优先级的定位参考信号，则可以对该定位参考信号进行测量，以测量得到定位参考信号的测量结果。
本申请实施例提供的方法，终端接收第一配置信息，且该第一配置信息指示 无需基于测量间隔进行测量的定位参考信号，因此终端测量定位参考信号无需受测量间隔周期性出现的影响，并且也无需由网络设备配置测量间隔，缩减了定位参考信号的测量时延，并且还提高了终端的通信效率。
在图2所示的实施例的基础上，第一配置信息包括至少一种参数。
在一些实施例中，第一配置信息包括以下至少一项：
(1)定位参考信号集合的集合标识，定位参考信号集合包括至少一个定位参考信号资源。
其中，定位参考信号资源用于传输定位参考信号，集合标识指示对应的定位参考信号集合。
在本申请实施例中，每个定位参考信号均属于某一个定位参考信号集合。若在第一配置信息中包括定位参考信号集合的集合标识，即可根据该集合标识确定对应的定位参考信号集合，进而确定该定位参考信号集合包括的至少一个定位参考信号资源。
(2)定位参考信号资源的资源标识。
其中，该资源标识指示定位参考信号所在的资源。任一个定位参考信号需要通过资源进行传输，若第一配置信息中包括资源标识，即可根据该资源标识确定对应的定位参考信号资源，定位参考信号基于该确定的定位参考信号资源进行传输。
(3)定位参考信号占用的时域位置。
(4)定位参考信号占用的频域位置。
(5)定位参考信号的序列标识。
其中，该序列标识指示定位参考信号的序列。任一定位参考信号均为一个序列，若第一配置信息中包括序列标识，即可根据该序列标识确定定位参考信号的序列。
本申请实施例通过第一配置信息中包括的至少一项参数来指示定位参考信号所在的资源，进而终端基于该第一配置信息确定优先级为目标优先级的定位参考信号，定位参考信号的测量无需受测量间隔周期性出现的影响，并且也无需由网络设备配置测量间隔，缩减了定位参考信号的测量时延，并且还提高了终端的通信效率。
在另一些实施例中，第一配置信息还包括以下任一项：
第一种：定位参考信号为周期性发送。
第二种：定位参考信号为非周期性发送。
第三种：定位参考信号为半永久性(semi-persistent)发送。
在本申请实施例中，第一配置信息中包括定位参考信号的传输方式，通过该第一配置信号即可确定定位参考信号的传输方式。
在一些实施例中，第一配置信息中包括传输方式的传输方式标识。例如，若传输方式标识为1，说明定位参考信号为周期性发送。若传输方式标识为2，说明定位参考信号为非周期性发送。若传输方式标识为3，说明定位参考信号为半永久性发送。
在图2所示的实施例的基础上，第一配置信息可以由不同的设备发送。其中，第一配置信息可以由位置服务器发送，或者由接入网设备发送。
在一些实施例中，第一配置信息由位置服务器发送，具体步骤参见图3：
步骤210：位置服务器发送第一配置信息。
在本申请实施例中，由位置服务器直接确定优先级为目标优先级的定位参考信号，基于该定位参考信号以及该定位参考信号所在的资源确定第一配置信息，进而发送第一配置信息。
其中，位置服务器不仅向终端发送该第一配置信息，还会向接入网设备(如终端的服务小区所在的gNB)发送第一配置信息。
位置服务器发送第一配置信息后，终端和接入网设备均可以根据该第一配置信息确定优先级为目标优先级的定位参考信号，进而终端和接入网设备均可以根据第一配置信息确定目标优先级的定位参考信号无需基于测量间隔进行测量。
本申请实施例提供的方法，直接由位置服务器请求确定传输定位参考信号的定位参考信号资源，基于确定的定位参考信号资源确定第一配置信息，以指示终端无需受测量间隔周期性出现的影响，并且也无需由网络设备配置测量间隔，缩减了定位参考信号的测量时延，并且还提高了终端的通信效率。
需要说明的是，本申请实施例仅是以位置服务器直接向终端发送第一配置信息为例进行说明。在另一实施例中，需要由终端发送资源请求信息以使位置服务器确定并发送第一配置信息。具体步骤参见图4：
步骤401：终端向位置服务器发送资源请求信息，资源请求信息包括定位参考信号的建议配置信息，建议配置信息指示定位参考信号的优先级为目标优先级。
其中，该建议配置信息指示终端自行确定的优先级为目标优先级的定位参考信号。
在一些实施例中，该建议配置信息包括以下至少一项：
(1)定位参考信号集合的集合标识，定位参考信号集合包括至少一个定位参考信号资源。
(2)定位参考信号资源的资源标识。
(3)定位参考信号占用的时域位置。

步骤402：位置服务器接收终端发送的资源请求信息。
步骤403：位置服务器确定第一配置信息。
在本申请实施例中，终端向位置服务器发送包括建议配置信息的资源请求信息，则位置服务器可以接收该资源请求信息，位置服务器接收到终端发送的建议配置信息后，即可根据该建议配置信息确定第一配置信息，该第一配置信息即可指示无需基于测量间隔进行测量的定位参考信号。
在一些实施例中，位置服务器直接将建议配置信息确定为第一配置信息。
在另一些实施例中，位置服务器先根据该建议配置信息确定该建议配置信息指示的定位参考信号，再从这些定位参考信号中确定优先级为目标优先级的定位参考信号，进而基于目标优先级的定位参考信号确定第一配置信息。
例如，若建议配置信息指示的定位参考信号中包括优先级低于其他信号的优先级的定位参考信号，则将这些定位参考信号排除，基于剩余的定位参考信号确定第一配置信息。
步骤404：位置服务器发送第一配置信息。
在本申请实施例中，位置服务器确定第一配置信息后，即可发送该第一配置信息。
其中，位置服务器不仅向终端发送该第一配置信息，还会向接入网设备发送第一配置信息，终端和接入网设备均接收到第一配置信息后，即可确定优先级为目标优先级的定位参考信号。
本申请实施例提供的方法，位置服务器根据终端发送的建议配置信息确定第一配置信息，提高了确定的第一配置信息的准确性。
上述图4所示的实施例对终端发送包括建议配置信息的资源请求信息进行说明。而另一实施例中，终端还可以发送包括第一配置信息的资源请求信息，具体参见图5所示的实施例：
步骤501：终端向位置服务器发送资源请求信息，资源请求信息包括第一配置信息。
步骤502：位置服务器接收终端发送的资源请求信息。
步骤503：位置服务器发送第一配置信息。
在本申请实施例中，终端向位置服务器发送包括第一配置信息的资源请求信息，位置服务器直接获取资源请求信息中的第一配置信息，无需对第一配置信息进行处理，即可发送该第一配置信息。
其中，位置服务器不仅向终端发送该第一配置信息，还需要向网路设备发送该第一配置信息。
本申请实施例提供的方法，终端发送包括第一配置信息的资源请求信息后，位置服务器接收该资源请求信息后，直接发送该资源请求信息中包括的第一配置信息，无需位置服务器对第一配置信息进行处理，减少信令开销，提高传输效率。
在一些实施例中，第一配置信息由接入网设备发送，具体步骤参见图6：
步骤601：接入网设备接收资源请求信息，资源请求信息包括定位参考信号的建议配置信息，建议配置信息指示定位参考信号的优先级为目标优先级。
其中，该资源请求信息中包括的建议配置信息供接入网设备参考，以便于接入网设备根据该建议配置信息确定目标优先级的定位参考信号。
步骤602：接入网设备确定第一配置信息。
在一些实施例中，接入网设备直接将建议配置信息确定为第一配置信息。
在另一些实施例中，接入网设备先根据该建议配置信息确定该建议配置信息指示的定位参考信号，再从这些定位参考信号中确定优先级为目标优先级的定位参考信号，进而基于目标优先级的定位参考信号确定第一配置信息。
例如，若建议配置信息指示的定位参考信号中包括优先级低于其他信号的优先级的定位参考信号，则将这些定位参考信号排除，基于剩余的定位参考信号确定第一配置信息。
需要说明的是，本申请实施例仅是以步骤602为例进行说明。在另一实施例中，还可以不执行步骤602，接入网设备采用其他方式确定第一配置信息，再执行步骤603。
步骤603：接入网设备发送第一配置信息。
