本申请主张在2021年07月23日在中国提交的中国专利申请No.202110839586.0的优先权，其部内容通过引用包含于此。
技术领域
本申请属于通信领域，特别涉及一种感知方法、装置及网络设备。
背景技术
未来移动通信系统例如B5G系统或6G系统除了具备通信能力外，还将具备感知能力。感知能力，即具备感知能力的一个或多个设备，能够通过无线信号的发送和接收，来感知目标物体的方位、距离、速度等信息，或者对目标物体、事件或环境等进行检测、跟踪、识别、成像等。未来随着毫米波、太赫兹等具备高频段大带宽能力的小基站在6G网络的部署，感知的分辨率相比厘米波将明显提升，从而使得6G网络能够提供更精细的感知服务。
感知的目的主要分为两大类。第一类目的是感知用于辅助通信或者增强通信性能，例如，基站通过跟踪设备的移动轨迹以提供更精准的波束赋型对准设备；另一类目的是与通信没有直接关系的感知，例如基站通过无线信号对天气情况进行监测，手机通过毫米波无线感知识别用户的手势等等。
感知方式可以分为以下几种：
(1)主动感知：如图1所示，设备利用自身发射信号的反射信号例如回波进行感知，收发机位于同一位置，可采用不同天线，可以感知设备周围环境信息；
(2)被动感知：如图2所示，收发机位于不同位置，接收机利用发送机发射的无线信号进行感知，例如基站A通过接收来自基站B的无线信号感知基站A和基站B之间的环境信息。
(3)交互感知：感知者与目标对象之间通过信息交互，对电磁波发送的 主体、时间、频率、格式等进行约定，完成感知的过程。
相关技术中并没有无线感知的相关流程，造成通信流程不完整。
