本公开实施例涉及通信技术领域,尤其涉及一种射频结构及终端设备。
5G网络在发展建设过程中会采用两种组网方式:非独立组网(Non-standalone,NSA)和独立组网(Standalone,SA)。
两种组网方式对技术要求和实现方式有不同的需求。以NSA模式下为例,需满足如下技术需求,如:(1)、长期演进(Long Term Evolution,LTE)与5G新空口(New Radio,NR)基于双连接(E-UTRA-NR Dual Connectivity,EN-DC)的方式进行通信,即LTE频段与NR频段能够同时工作;(2)、NR频段需要支持1T4R(1发4收)的探测参考信号(Sounding Reference Signal,SRS)天线轮流发射技术。另外,当独立工作于LTE模式时,也希望支持双天线或多天线切换及下行4*4多输入多输出(Multiple-Input Multiple-Output,MIMO)。
相关技术中存在多种NSA模式下的射频结构。但是,在这些结构中均采用了较多根数的天线。例如,有些结构中,LTE和NR分别采用4天线设计。因此,这无形中增加了天线的设计难度。
