图1是本申请实施例的一个应用场景的示意图。
如图1所示，通信系统100可以包括终端110和网络设备120，或者不包含终端110只包括网络设备120。网络设备120可以通过空口与终端110通信。终端110和网络设备120之间支持多业务传输。
应理解，本申请实施例仅以通信系统100进行示例性说明，但本申请实施例不限定于此。也就是说，本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile  Telecommunication System，UMTS)、物联网(Internet of Things，IoT)系统、窄带物联网(Narrow Band Internet of Things，NB-IoT)系统、增强的机器类型通信(enhanced Machine-Type Communications，eMTC)系统、5G通信系统(也称为新无线(New Radio，NR)通信系统)，或未来的通信系统等。
在图1所示的通信系统100中，网络设备120可以是与终端110通信的接入网设备。接入网设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端110(例如UE)进行通信。

为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
移动通信技术的发展催生了智慧交通、智慧城市、智慧医疗、智慧气 象监控、智慧工厂、无人机等，除通信需求外，这些新兴业务同样具有感知的需求。现有传统感知技术需安装部署专门设备或器件，如传感器、摄像头和雷达等，应用场景和性能受限，无法满足未来业务的需求。在此背景下，通信与感知的融合技术被提出。
当前第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)正在开展通信感知技术的立项讨论，该技术利用5G-A基站(NG-RAN)或终端收发无线电波同时实现通信和感知功能，若基站执行感知，可通过部署通信感知一体化基站或升级已部署基站实现感知信息的获取和处理。当基站和/或终端接收到传输信号和/或回波信号后，先在本地提取感知信息并进行处理，之后将处理过的感知数据传递到核心网网元进行计算，得到目标的位置、速度和大小等信息作为感知结果输出，最终，感知结果可提供给终端和/或核心网网元和/或第三方应用平台或控制平台辅助第三方进行决策。
当前通信感知技术处于立项讨论阶段，网络架构和流程等均未定义。
通信感知技术典型的应用场景有自动驾驶、无人机监管、火车道异物检测、健康监测等，大部分场景只需要部分基站和/或终端执行感知即可。比如，对于火车道异物的感知只需铁道沿线的基站参与，对于无人机的感知只需无人机飞行区域内的基站参与。若所有基站均参与感知，将向核心网传输大量数据，对核心网网元和传输网络造成压力，影响传输和处理效率。此外，同一区域可能同时存在支持通信和感知的基站和只支持通信的基站，若核心网网元向所有基站发送感知请求，不支持感知的基站可能因不能识别该请求造成错误，造成额外的性能和信令开销。同时，若基站本身通信负载较重，可能无足够资源执行感知，一方面会影响感知性能，另一方面会影响通信性能。
为此，提出了本申请实施例的以下技术方案。本申请实施例的技术方 案，通过基于基站能力、区域以及感知业务中的至少之一选择用于感知的基站(简称为感知基站)，以解决区域感知场景中的基站选择问题，该方案也可用于终端执行感知的场景。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
