技术领域
本发明涉及通信设备技术领域，尤其涉及一种射频电路、电子设备及SRS发送方法。
背景技术
随着第五代移动通信技术(5 th Generation，5G)时代的到来，在电子设备的射频电路中，为了实现独立组网(Standalone，SA)的两路发射四路接收2T4R兼容非独立组网(Non-Standalone，NSA)的一路发射四路接收1T4R，通常射频电路设计的较为复杂。具体的如图1，现有的射频电路中，通常设置两个3P3T开关控制独立组网收发模组10、非独立组网收发模组11发送探测参考信号(Sounding Reference Signal，SRS)的状态。如图所示，独立组网收发模组10通过一个3P3T(即包括3个P端口和3个T端口，P端口是指Port端口，T端口是指Throw端口)开关与第一天线和第二天线连接，非独立组网收发模组11通过两个3P3T开关分别与第一天线12、第二天线13、第三天线14和第四天线15连接。由于将非独立组网收发模组10通过两个3P3T开关分别与第一天线12、第二天线13、第三天线14和第四天线15连接，从而导致射频电路的走线复杂。
发明内容
本发明实施例提供一种射频电路、电子设备及SRS发送方法，以解决射频电路的走线复杂的问题。
第一方面，本发明实施例提供了一种射频电路，其特征在于，包括：独立组网收发模组、非独立组网收发模组、第一天线、第二天线、第三天线、 第四天线、第一选择开关和第二选择开关；其中，

附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对本发明实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
除非另作定义，本发明中使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本发明中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”或者“一”等类似词语也不表示数量限制，而是表示存在至少一个。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也相应地改变。
参见图2，本发明实施例提供了一种射频电路，包括：独立组网收发模组10、非独立组网收发模组11、第一天线12、第二天线13、第三天线14、第四天线15、第一选择开关16和第二选择开关17；其中，
所述独立组网收发模组10与所述第一选择开关16电连接，所述第一选择开关16用于控制所述独立组网收发模组10与所述第一天线12或所述第二天线13电连接；
所述非独立组网收发模组11与所述第二选择开关17电连接，所述第二选择开关17用于控制所述非独立组网收发模组11与所述第三天线14或所述第四天线15电连接。
本发明实施例中，上述独立组网收发模组包括第一射频接收电路、第一射频发送电路和第一切换开关等电路结构，其中第一射频发送电路包括第一射频功率放大器(即SA PA)。同样的，上述非独立组网收发模组包括第二射频接收电路、第二射频发送电路和第二切换开关等电路结构，其中第一射频发送电路包括第一射频功率放大器(即NSA PA)。
其中，在SA模式下，独立组网收发模组10、第一选择开关16、第一天线12和第二天线13构成第一路发射TX1；非独立组网收发模组11、第二选择开关17、第三天线14和第四天线15构成第二路发射TX2。其中，在TX1中通过第一选择开关16控制将独立组网收发模组10输出的SRS发射到第一天线12和第二天线13；，在TX2中通过第二选择开关17控制将非独立组网收发模组11输出的SRS发射到第三天线14和第四天线15。这样，本发明实施例，可以在SA模式下实现2T4R功能。
在NSA模式下，非独立组网收发模组11中的NSA PA作为NSA PA，将SRS发射到第三天线14和第四天线15；独立组网收发模组10中的SA PA同样也作为NSA PA，可以通过软件配置将SRS发射到第一天线12和第二天线13。这样，本发明实施例，可以在NSA模式下实现1T4R功能。
本发明实施例通过设置所述独立组网收发模组10与所述第一选择开关16电连接，所述第一选择开关16用于控制所述独立组网收发模组10与所述第一天线12或所述第二天线13电连接；设置所述非独立组网收发模组11与所述第二选择开关17电连接，所述第二选择开关17用于控制所述非独立组网收发模组11与所述第三天线14或所述第四天线15电连接，从而可以实现SA的2T4R兼容NSA的1T4R。由于，第一选择开关16仅与第一天线12和第二天线13连接，第二选择开关17仅与第三天线14和第四天线15连接，这样简化了射频电路的走线，降低了射频电路的走线难度。
进一步地，所述射频电路具有射频收发器18，所述射频收发器18与所述独立组网收发模组10、非独立组网收发模组11、第一选择开关12和第二 选择开关13电连接，用于在非独立组网模式下控制所述独立组网收发模组通过所述第一天线12和第二天线13发送探测参考信号SRS，控制所述非独立组网收发模组通过所述第三天线和第四天线发送SRS。
本发明实施例中，射频收发器18可以输出控制信号至第一选择开关16，通过第一选择开关12在不同时隙切换独立组网收发模组10分别与第一天线12和第二天线13连接，从而通过第一天线12和第二天线13发送SRS。此外，射频收发器18可以输出控制信号至第二选择开关17，通过第二选择开关17在不同时隙切换非独立组网收发模组11分别与第三天线14和第四天线15连接，从而通过第三天线14和第四天线15发送SRS。本实施例中，上述独立组网收发模组10中SA PA和非独立组网模组11中的NSA PA均可以看作为NSA PA，以实现NSA模式下的1T4R功能。
可选地，在一实施例中，在独立组网模式下，上述射频收发器18还用于控制所述独立组网收发模组10通过所述第一天线12和第二天线13发送SRS，控制所述非独立组网收发模组11通过所述第三天线14和第四天线15发送SRS。
本发明实施例中，独立组网收发模组10中的SA PA作为一路发射，射频收发器18可以输出控制信号至第一选择开关16，通过第一选择开关12在不同时隙切换独立组网收发模组10分别与第一天线12和第二天线13连接，从而通过第一天线12和第二天线13发送SRS。此外，非独立组网收发模组11中的NSA PA作为另一路发射，射频收发器18可以输出控制信号至第二选择开关17，通过第二选择开关17在不同时隙切换非独立组网收发模组11分别与第三天线14和第四天线15连接，从而通过第三天线14和第四天线15发送SRS。这样，本实施例可以实现SA的2T4R功能。
可选地，上述第一选择开关16和第二选择开关17的结构可以根据实际需要进行设置，例如，在一实施例中，上述第一选择开关16为单刀双掷开关或者双刀双掷开关，同样的，上述第二选择开关17为单刀双掷开关或者双刀双掷开关。由于采用单刀双掷开关或者双刀双掷开关作为选择开关，相对于现有技术采用3P3T开关，本发明实施例可以降低射频电路的成本。
具体的，在一实施例中，当所述第一选择开关16为单刀双掷开关时，所 述独立组网收发模组10与所述第一选择开关16的P端口电连接，所述第一天线12与所述第一选择开关16的一个T端口电连接，所述第二天线13与所述第一选择开关16的另一个T端口电连接。
当所述第二选择开关17为单刀双掷开关时，所述非独立组网收发模组11与所述第二选择开关17的P端口电连接，所述第三天线14与所述第二选择开关17的一个T端口电连接，所述第四天线15与所述第二选择开关17的另一个T端口电连接。
其中，P端口是指Port(极化)端口，T端口是指Throw(投、掷)端口，单刀双掷开关可以理解为SPDT开关。
进一步地，本发明实施例还提供一种电子设备，该电子设备包括上述实施例中的射频电路，该射频电路的结构以及工作原理可以参照上述实施例，在此不再赘述。由于本发明实施例提供的电子设备采用了上述实施例中的射频电路，因此，本发明实施例提供的电子设备具有上述实施例中射频电路的全部有益效果。
可选地，在一实施例中，所述第一天线和所述第二天线设置于所述电子设备的壳体的一侧边沿，所述第三天线和所述第四天线设置于所述电子设备的壳体的另一侧边沿，所述独立组网收发模组和所述非独立组网收发模组间隔设置。本发明实施例中，上述第一天线和第二天线可以设置在所述电子设备的壳体的两相背侧，这样，可以减小第一天线和第二天线之间的干扰。
进一步地，参照图3，本发明实施例还提供一种探测参考信号SRS发送方法，应用于上述电子设备，包括以下步骤：
步骤301，在非独立组网模式下，控制独立组网收发模组通过第一天线和第二天线发送SRS，控制非独立组网收发模组通过第三天线和第四天线发送SRS。
可选地，所述方法还包括：
在独立组网模式下，控制独立组网收发模组通过第一天线和第二天线发送SRS，控制非独立组网收发模组通过第三天线和第四天线发送SRS。
本发明实施例通过设置所述独立组网收发模组与所述第一选择开关电连接，设置所述非独立组网收发模组与所述第二选择开关电连接，在非独立组 网模式下，控制独立组网收发模组通过第一天线和第二天线发送SRS，控制非独立组网收发模组通过第三天线和第四天线发送SRS；在独立组网模式下，控制独立组网收发模组通过第一天线和第二天线发送SRS，控制非独立组网收发模组通过第三天线和第四天线发送SRS，从而可以实现SA的2T4R兼容NSA的1T4R。
