应理解，在本申请的一些实施例中，上述5GNR系统还可以称为5G系统或者NR。本申请的一些实施例中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，还可以适用于6G以及后续的演进系统。
由于蜂窝网络所使用的无线电磁波信号不但可以用于无线数据传输和通信，同时还具有环境感知能力，例如，用户的动作或者手势识别、呼吸监测、终端移动速度测量、环境成像、天气监测等。因此在未来的蜂窝网络可以考虑不只是用于通信和数据传输，还可以用于感知信息的获取。
当前，正在讨论在B5G网络中支持感知能力，通过增加感知控制网元(Sensing Function，SF)及相应流程在3GPP网络中支持感知功能。在感知功能的实现中，可以根据感知目标的不同，将感知测量划分为有源感知和无源感知。其中，有源感知的感知目标是UE，即，是UE级别的感知；无源感知的感知目标是目标区域或者目标对象，即，区域级别的感知没有特定的UE，不属于3GPP。
在一个示例中，如图2所示，其示出了本申请一个示例性实施例提供的UE级别感知的流程图，该流程包括：S21，AF向感知控制网元发送感知请求，感知请求中包括UE信息、感知类型；S22，感知控制网元向移动性管理网元发送第一感知指令，第一感知指令中包括UE信息和感知类型；S23，移动性管理网元确定UE感知方式或基站感知方式；S241，移动性管理网元向接入网设备发送第二感知指令，第二感知指令包括感知类型；S242，接入网设备和目标UE之间通过接入层信号进行感知测量；S243，接入网设备产生感知数据；S251，移动性管理网元向目标UE发送第二感知指令，第二感知指令中包括感知类型；S252，目标UE和接入网设备之间通过接入层信号进行感知测量；S253，目标UE产生感知数据。其中，S241～S243是基站感知方式对应的步骤，S251～S253是UE感知方式对应的步骤。
在另一个示例中，如图3所示，其示出了本申请一个示例性实施例提供的区域级别感知的流程图，该流程包括：S31，AF向感知控制网元发送感知请求，感知请求中包括第一目标区域和感知类型；S32，感知控制网元向移动性管理网元发送第一感知指令，第一感知指令中包括第二目标区域和感知类型；S33，移动性管理网元确定感知基站；S34，移动性管理网元向接入网设备发送第二感知指令，第二感知指令中包括第三目标区域和感知类型；S35，接入网设备确定辅助UE或辅助基站；S36，接入网设备和辅助UE或基站通过接入层信号进行感知测量；S37，接入网设备产生感知数据。
其中，上述两个示例中，是通过终端和基站之间的协作感知所实现的感知测量过程，除此之外，还包括其他通感一体化的无线感知场景。示意性的，通感一体化主要的无线感知场景包括：
1)基站回波感知链路(单gNB感知)：基站发送感知信号并接收回波信号；
2)基站间感知链路(gNB-gNB感知)：基站B接收基站A发送的感知信号；
3)空口上行感知链路(UE-gNB上行感知)：基站接收终端发送的感知信号；
4)空口下行感知链路(UE-gNB下行感知)：终端接收基站发送的感知信号；
5)终端回波感知链路(单UE感知)：终端发送感知信号并接收回波信号；
6)终端间感知链路(UE-UE感知)：终端B接收终端A发送的感知信号。
值得注意的是，在B5G通信感知一体化的初期阶段，考虑尽量复用现有的空口信号执行感知行为，不引入过多的空口增强；且考虑到全双工实现的复杂度，终端和/或基站之间协作感知是优先考虑的方向。
感知节点的选择：
如果感知目标为per-UE(有源感知)，则说明已经有明确的目标UE，因此感知节点选择过程可以得到简化，只需要寻找目标UE周围存在的其他UE或gNB作为感知辅助节点，共同完成感知任务，即，目标UE作为感知节点，其他UE或gNB作为感知辅助节点，其中，感知节点和感知辅助节点均为感知测量中的感知参与节点。对于UE-UE感知，即，寻找目标UE周围存在的其他UE作为感知辅助节点，可以通过侧行发现(Sidelink Discovery)或者R18侧行定位(Sidelink Positioning)确定UE附近存在的可用的候选感知节点(UE)；对于UE-gNB感知，即，寻找目标UE周围存在的gNB作为感知辅助节点，SF或AMF能够知道目标UE的服务gNB以及邻区gNB的确切位置，可以利用现有的邻区测量上报机制等，例如， 基于参考信号接收功率(Reference Signal Receiving Power，RSRP)或参考信号接收质量(Reference Signal Receiving Quality，RSRQ)的测量结果，从目标UE的服务gNB及邻区gNB中选择合适的感知节点(gNB)。
如果感知目标为per-area(无源感知)，即需要针对目标区域寻找合适的gNB或UE作为感知节点或感知辅助节点。对于仅gNB参与的感知场景，例如，基站回波感知和基站间感知，感知节点选择过程需要寻找目标区域周围存在的gNB作为感知节点。由于SF或AMF知道所有gNB的位置，不需要额外的辅助信息，SF或AMF就可以直接选择目标区域或附近合适的gNB做为感知节点或感知辅助节点。但是对于有UE参与的感知场景，例如，空口上行感知、空口下行感知、终端回波感知、终端间感知，感知节点选择过程需要寻找目标区域周围存在的UE作为感知节点或感知辅助节点，而gNB、SF和AMF并不能确切知道目标区域或附近的UE分布情况，需要考虑UE上报辅助信息或其他机制。针对目标区域，核心网的SF或者AMF负责选择合适的gNB，而辅助UE的选择除了SF或AMF外，还可能由gNB负责。
针对有UE参与的、感知目标为区域级别的感知场景，核心网的SF/AMF/gNB负责选择目标区域周围的合适的辅助UE作为感知节点参与感知测量，由于SF、AMF和gNB不能确切知道目标区域或附近的UE分布情况。因此，在针对目标区域进行感知测量的过程中，存在无法为目标区域配置合适的辅助UE作为感知节点的问题。
针对上述问题，本申请实施例提供了一种感知节点的确定方法，提供了确定感知节点的解决方案。请参考图4，其示出了本申请一个示例性实施例提供的感知节点的确定方法的流程图，本实施例以该方法由第一设备执行为例进行说明，其中，第一设备可以是终端设备，也可以是接入网设备。该方法包括如下步骤：

在一些实施例中，第一设备对获取到的位置信息进行有效性检测，在第一设备的位置信息为有效信息的情况下，基于第一设备的位置信息和AOI的信息，向第二设备发送反馈消息。在一个示例中，当第一设备获取到的非即时测量的位置信息是有效信息时，可以将上述位置信息直接用于基于位置信息和AOI发送反馈消息的过程，即，不需要即时触发位置信息的测量。
可选地，第一设备向第二设备发送的反馈消息用于指示第一设备的位置信息和AOI之间的匹配结果，即，第一设备向第二设备反馈位置信息和AOI之间的匹配结果，第二设备根据反馈消息确定第一设备是否在兴趣区域，并在兴趣区域内的第一设备中选择作为感知节点的设备；或者，第一设备向第二设备发送的反馈消息用于指示第一设备是否能够参与感知测量，即，当第一设备位于兴趣区域时，向第二设备发送指示能够参与感知测量的反馈消息，当第一设备不在兴趣区域内时，向第二设备发送指示不能参与感知测量的反馈消息，第二设备根据第一设备是否能够参与感知测量，从第一设备中选择作为感知节点的设备。
示意性的，第一设备根据位置信息和AOI之间的匹配情况，向第二设备发送反馈消息。可选地，第一设备根据位置信息和AOI之间的不同匹配情况，向第二设备发送不同的反馈消息。在第一设备的位置信息属于AOI的情况下，向第二设备发送第一反馈消息，第一反馈消息用于指示第一设备参与感知测量；在第一设备的位置信息不属于AOI的情况下，向第二设备发送第二反馈消息，第二反馈消息用于指示第一设备不参与感知测量。即，当第二设备接收到第一设备发送的反馈消息时，若反馈消息是第一反馈消息，则确定第一设备参与感知测量，若反馈消息是第二反馈消息，则确定第一设备不参与感知测量。
可选地，第一设备仅在位置信息和AOI匹配的情况下，向第二设备发送第一反馈消息。在第一设备的位置信息属于AOI的情况下，向第二设备发送反馈消息；在第一设备的位置信息不属于AOI的情况下，结束流程。当第二设备接收到第一设备发送的反馈消息时，则说明第一设备期望参与感知测量，当第二设备未接收到第一设备的反馈消息，则说明第一设备不参与感知测量。
在一些实施例中，除了根据第一设备的位置信息和AOI之间的匹配情况进行反馈消息的发送之外，第一设备还可以根据设备自身是否愿意参与感知测量进行设置。
在一个示例中，在第一设备的位置信息属于AOI，但第一设备的设置信息指示第一设备不参与感知测量的情况下，向第二设备发送第二反馈消息。即，当第一设备的位置处于AOI中，但第一设备不希望成为感知节点时，向第二设备发送第二反馈消息。
在另一个示例中，第一设备在接收到感知请求消息时，先根据第一设备的设置信息确定第一设备是否希望参与感知测量，在确定第一设备的设置信息指示第一设备不参与感知测量的情况下，第一设备直接向第二设备反馈第二反馈消息，或者，第一设备不发送反馈消息，以指示第一设备不参与感知测量；当第一设备的设置信息指示第一设备希望参与感知测量时，根据第一设备的位置信息和感知请求消息中的AOI信息进行反馈消息的发送。

可选地，上述预配置的RACH资源可以由网络设备通过RRC信令预先配置给候选终端。
步骤1040，网络设备根据反馈消息将候选终端选择为感知节点。
