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。典型的感知功能与应用场景如表1所示。
表1典型的感知功能与应用场景对照表
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,具体包括:
(1)基站回波感知;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;此时,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;此时,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;此时,终端B接收基站B发送的感知信号,进行感知测量。
(5)终端回波感知;此时,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;此时,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,实际***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。
二、切换
切换是连接状态下UE的移动触发,切换的基本目标为:
指示UE可与比当前服务小区信道质量更好的小区通信;
为UE提供连续的无中断的通信服务,有效防止由于小区的信号质量变差造成的掉话。
