摘　　要：通信与感知的融合作为6G重要的研究课题,实现了通信和感知的互相赋能和二者产业的融合。首先对通信感知一体化在标准化和产业界发展进行介绍。其次,在组网环境下研究感知能力,通过宏微基站的配合实现通感融合的多点协同感知。协同方式根据具体场景可以采用不同形式,既可以通过基站间通信接口实现感知数据的共享,也可以通过多基站感知数据的合并和互补提高感知的精度和全面性。为了提高频谱效率,通信和感知可以共享空口资源,设计了二者间的资源协同机制,避免了通信和感知间的干扰。除此之外,面向未来感知类业务提出了感知Qo S概念,从网络角度研究感知Qo S保障机制。最后,展望了通感一体化网络的演进趋势,并分析了未来面临的挑战。As an important research topic of 6G,integrated sensing and communication achieve the mutual empowerment and industrial integration of sensing and communication.Firstly,the standardization process and industrial development of integrated sensing and communication are briefly introduced.Secondly,the sensing capacity in the networking environment is investigated,and the integrated sensing and communication multi-point collaborative sensing is achieved through the collaboration of macro and micro base stations.There are many different forms of collaboration,depending on the specific scenario.It can not only share sensing data through the communication interface between base stations,but also improve the accuracy and comprehensiveness of sensing by combining and complementing the perception data of multiple base stations.In order to improve spectrum efficiency,sensing and communication can share air interface resources,and a resource allocation mechanism is designed to avoid interference between sensing and communication.Moreover,the concept of sensing QoS is proposed for future perceptual services,and the guarantee mechanism of sensing QoS is studied from the perspective of the network.Finally,we look forward to the evolution trend of the integrated sensing and communication network and point out the challenges faced in the future.
