下面对本申请涉及的技术内容进行简单说明。
1.通信感知一体化/通感一体化:
通信和感知一体化(Integrated Sensing And Communication,ISAC)通过硬件设备共用和软件定义功能的方式获得通信和感知双功能的一体化低成本实现,特点主要有:一是架构统一且简化,二是功能可重构可扩展,三是效率提升、成本降低。通信感知一体化的优势主要有三个方面:一是设备成本降低、尺寸减小,二是频谱利用率提升,三是系统性能提升。
目前,根据5G通信系统架构进行技术升级而有望实现的典型通信感知一体化的场景如表1所示。
表1通信感知一体化典型场景
根据感知信号发送节点和接收节点的不同,分为6种基本感知方式,如图2所示,具体包括:
(1)基站自发自收感知:在这种感知方式下,基站A发送感知信号,并通过接收该感知信号的回波来进行感知测量。
(2)基站间空口感知:基站B接收基站A发送的感知信号,进行感知测量。
(3)上行空口感知:基站A接收终端A发送的感知信号,进行感知测量。
(4)下行空口感知:终端B接收基站B发送的感知信号,进行感知测量。
(5)终端自发自收感知:终端A发送感知信号,并通过接收该感知信号的回波来进行感知测量。
(6)终端间旁链路(Sidelink)感知:终端B接收终端A发送的感知信号,进行感知测量。
值得注意的是,图2中每种感知方式都以一个感知信号发送节点和一个感知信号接收节点作为例子,实际系统中,根据不同的感知用例和感知需求可以选择一种或多种不同的感知方式,且每种感知方式的发送节点和接收节点可以有一个或多个。图2中的感知目标以人和车作为例子,且假设人和车均没有携带或安装信号收/发设备,实际场景的感知目标将更加丰富。
2.感知视距(Line of Sight,LOS)和非视距(Non Line of Sight,NLOS)
在通信中LOS和NLOS是根据发送端和接收端的视距径来定义的。在感知中LOS和NLOS是根据感知方(感知发送端和感知接收端)和感知目标之间是否存在遮挡来判断的,如果存在遮挡,即认为是NLOS,如果不存在遮挡,即认为是LOS。
下面对单站感知模式和双站感知模式中LOS和NLOS进行说明。
1)单站感知模式中,根据信道互异性,感知发送端到感知目标的路径和感知目标到感知接收端的路径可以认为具有相同的LOS概率。存在如图3所示的两种情况。
2)双站感知模式中,感知发送端到感知目标的路径和感知目标到感知接收端的路径其LOS概率是不同的,需要分别计算。存在如图4所示的四种情况。
