Description

实现载波聚合和WIFI双频MIMO的控制电路、终端
本申请要求于2015年12月31日提交中国专利局，申请号为201511029064.5、发明名称为“实现载波聚合和WIFI双频MIMO的控制电路、终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及天线技术领域，具体而言，涉及一种实现载波聚合和WIFI双频MIMO的控制电路和一种终端。
背景技术
目前，中国移动、中国联通、中国电信三大运营商都在积极升级网络，部署CA(Carrier Aggregation，载波聚合)，目前由于中国移动CA要求是B39(Band39)和B41(Band41)的载波聚合，所以采用双工滤波器的方案进行载波聚合，而中国联通和中国电信属于FDD-LTE(Frequency Division Duplexing-Long Term Evolution，频分双工-长期演进)，要求B1(Band1)+B3(Band3)的载波聚合，而FDD-LTE的方案目前是采用四工器的方案，实现下行同时接受B1和B3两种FDD-LTE信号。
另外，目前实现载波聚合的终端(比如手机)实现WIFI(Wireless Fidelity，无线宽带)双频的SISO(Single Input Single Out，单入单出)的方式居多，实现WIFI MIMO(Multiple Input Multiple Out，多入多出)的比较少，主要是由于终端空间有限，导致增加天线数使得终端设计难度增加。
上述现有的技术方案，采用四工器器件成本非常高，而且插损过大,使得PA(Power Amplifier，功率放大器)输出更多的功率弥补四工器带来的插损，而且PA的ACLR(Adjacent Channel Leakage Ratio，相邻频道泄漏比)发射功率越大，电流偏大，效率低下。且当终端处于在非CA状态下，PA的发射功率仍然按照更大的功率值发射，造成不必要电流消耗。
因此，如何在不增加系统整体天线个数的情况下，同时实现载波聚合 功能和WIFI双频MIMO功能，且不额外增加PA的输出功率，从而降低终端功耗成为亟待解决的技术问题。
发明内容
本发明正是基于上述技术问题，提出了一种新的技术方案，可以在不增加系统整体天线个数的情况下，同时实现了载波聚合功能和WIFI双频MIMO功能，且不额外增加PA的输出功率，从而降低终端功耗。
有鉴于此，本发明的第一方面，提出了一种实现载波聚合和WIFI双频MIMO的控制电路，包括：第一天线、第二天线、第三天线、第四天线、第一开关、第二开关、第三开关、第四开关、收发器、WIFI收发器、第一滤波器组件、第二滤波器组件、第一分频器和第二分频器；其中，所述第一开关的一端连接至所述第一天线、另一端通过所述第一滤波组件连接至所述收发器，所述第一天线用于实现第一频段信号和第二频段信号的发射和主集接收；所述第二开关的一端连接至所述第二天线、另一端通过所述第二滤波组件连接至所述收发器，所述第二天线用于实现第三频段信号和第四频段信号的发射和主集接收；所述第三天线通过所述第一分频器分别连接至所述第三开关和所述WIFI收发器，用于实现所述第一频段信号和所述第二频段信号的分集接收；所述第四天线通过所述第二分频器分别连接至所述第四开关和所述WIFI收发器，用于实现所述第三频段信号和所述第四频段信号的分集接收；以及所述第三天线和第四天线还用于实现WIFI双频MIMO功能。
