技术领域

背景技术

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)。

在本公开实施例中,利用包括四根天线的天线模组即可满足NSA模式的技术要求。因此,与相关技术相比,利用本公开实施例减少了天线的数量,从而降低了天线设计的复杂度。
当仅工作于LTE时,可分为以下至少4种配置,用以实现LTE的双天线切换,同时可实现LTE DL 4*4 MIMO。以下,结合不同的附图详细描述各种配置。
如图13所示,为独立工作于LTE模式时的配置,可实现DL的4*4MIMO。在图13中,通过调节第一开关模组和第二开关模组,使得:
所述LTE TRx/NR接收模组311与所述第一天线331连接,用于发送LTE的信号或接收LTE第一端口Rx0的信号;
所述第二LTE/NR接收模组314与所述第二天线332连接,用于接收LTE第三端口Rx2的信号;

如图14所示,为独立工作于LTE模式时的配置,可实现DL的4*4MIMO。在图14中,通过调节第一开关模组和第二开关模组,使得:
所述LTE TRx/NR接收模组311与所述第二天线332连接,用于发送LTE的信号或接收LTE第一端口Rx0的信号;

当LTE与NR进行双连接时,由于基站的需求,终端设备的NR频段需 要在4根天线上进行SRS轮流发射,且NR频段需要支持DL 4*4 MIMO;同时本公开实施例有能力在双连接情况下支持LTE频段的DL 2*2 MIMO。在这种情况下,有以下四种配置。
如图15所示,为LTE与NR双连接状态下的LTE/NR默认配置。通过调节所述第一开关模组和所述第二开关模组使得:
所述LTE TRx/NR接收模组311与所述第一天线331连接,用于发送LTE的信号或接收LTE第一端口Rx0的信号,和/或,用于接收NR第三端口Rx2信号;
所述NR TRx模组312与所述第三天线连接333,用于发送NR的信号或接收NR第一端口Rx0的信号;
所述第二LTE/NR接收模组314与所述第二天线332连接,用于接收NR第二端口Rx1的信号;
所述第三LTE/NR接收模组315与所述第四天线334连接,用于接收LTE第二端口Rx1信号,和/或,用于接收NR第四端口Rx3的信号。
通过此配置,可实现LTE/NR双连接情况下的LTE DL 2*2 MIMO和NR DL 4*4 MIMO。
如图16所示,为LTE与NR双连接状态下的LTE/NR配置。通过调节所述第一开关模组和所述第二开关模组使得:

所述第三LTE/NR接收模组315与所述第四天线334连接,用于接收LTE第二端口Rx1信号,和/或,用于接收NR第四端口Rx3的信号。
与图15相比,此配置实现了NR频段的第三天线(ANT2)与第一天线(ANT0)配置进行交换,同时在此情况下,LTE频段可以实现双天线切换, 即LTE Tx可以在第三天线(ANT2)与第四天线(ANT3)之间进行切换。
如图17所示,为LTE与NR双连接状态下的LTE/NR配置。通过调节所述第一开关模组和所述第二开关模组使得:
所述LTE TRx/NR接收模组311与所述第一天线331连接,用于发送LTE的信号或接收LTE第一端口Rx0的信号,和/或,用于接收NR第三端口Rx2信号;
所述NR TRx模组312与所述第二天线332连接,用于发送NR的信号或接收NR第一端口Rx0的信号;
所述第二LTE/NR接收模组314与所述第三天线333连接,用于接收NR第二端口Rx1的信号;
所述第三LTE/NR接收模组315与所述第四天线334连接,用于接收LTE第二端口Rx1信号,和/或,用于接收NR第四端口Rx3的信号。
与图15相比,此配置实现了NR频段的第三天线(ANT2)与第二天线(ANT1)配置进行交换。
如图18所示,为LTE与NR双连接状态下的LTE/NR配置。通过调节所述第一开关模组和所述第二开关模组使得:
所述LTE TRx/NR接收模组311与所述第一天线331连接,用于发送LTE的信号或接收LTE第一端口Rx0的信号,和/或,用于接收NR第三端口Rx2信号;
所述NR TRx模组312与所述第四天线334连接,用于发送NR的信号或接收NR第一端口Rx0的信号;
所述第二LTE/NR接收模组314与所述第二天线332连接,用于接收NR第二端口Rx1的信号;
所述第三LTE/NR接收模组315与所述第三天线333连接,用于接收LTE第二端口Rx1信号,和/或,用于接收NR第四端口Rx3的信号。
与图15相比,此配置实现了NR频段的第三天线(ANT2)与第四天线(ANT3)配置进行交换。
通过以上描述可以看出,在本公开实施例中,能够实现LTE独立工作时的双天线切换及DL 4*4 MIMO;NSA模式下LTE与NR实现EN-DC的硬件 设计方案;支持EN-DC情况下NR频段的1T4R SRS天线轮发技术。同时本实施例仅需4根天线,有效降低了天线设计难度。
此外,在本公开实施例中,还可通过简化射频前端模组、开关模组及天线数量的配置来实现LTE及NR的2*2 MIMO。
本公开实施例中,上述射频结构可以应用于终端设备,例如:手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等。
