在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本申请实施例所涉及到的电子设备可以包括5G NR系统中各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)，客户签约设备(Customer Premise Equipment，CPE)或者便携式宽带无线装置(Mobile Wifi，MIFI)等等。为方便描述，上面提到的设备统称为电子设备。
目前，手机的SRS切换switching4天线发射功能是中国移动通信集团CMCC在《中国移动5G规模试验技术白皮书_终端》中的必选项，在第三代合作伙伴计划3GPP中为可选，其主要目的是为了基站通过测量手机4天线上行信号，进而确认4路信道质量及参数，根据信道互易性再针对4路信道做下行最大化多输入多输出Massive MIMO天线阵列的波束赋形，最终使下行4x4 MIMO获得最佳数据传输性能。
为满足FDD NR系统和/或FDD LTE系统中4天线SRS切换switching发射和下行4X4MIMO功能的同时工作的要求，本申请实施例提出的以简化的4PnT天线开关为核心的射频架构，和3P3T/DPDT/多路小开关切换方案比较，可以减少各路径串联开关数量(将所有或部分开关集合到4PnT开关中)，从而减少链路损耗，优化终端整体的发射接收性能。下面对本申请实施例进行详细介绍。
请参阅图1，图1是本申请实施例提供了一种多路选择开关10的结构示意图，该多路选择开关应用于电子设备100，所述电子设备100包括天线系统20和射频电路30，所述天线系统20包括4支天线，所述多路选择开关10包括n个T端口和4个P端口，所述n个T端口包括m个第一T端口和n-m第二T端口，所述电子设备支持单发模式，每个第一T端口全连接所述4个P端口，每个第二T端口连接所述4个P端口中的2个P端口，支持相同频段的信号接收功能的多个第二T端口所连接的P端口覆盖所述4个P端口，且处于信号接收状态的所述4个T端口中每个T端口所连接的P端口互不相同，m等于1或2或4，n为大于或等于4的整数；
所述多路选择开关10用于连接所述射频电路30和所述天线系统20以实现所述电子设备100在频分复用FDD制式中的预设功能，所述预设功能包括第一功能和第二功能，所述第一功能为支持通过探测参考信号SRS在发射天线间轮发，发送4端口SRS的功能，所述第二功能为支持所述4支天线同时接收数据的功能。
其中，所述支持通过探测参考信号SRS在发射天线间轮发，发送4端口SRS的功能是指电子设备通过轮训机制与基站交互确定每个天线对应的信道质量的过程。所述电子设备还包括射频收发器，该射频收发器连接所述射频电路，并与射频电路、多路选择开关以及天线系统组成该电子设备的射频系统。所述电子设备处于下行4*4多输入多输出MIMO工作模式时，同一频段的4个下行通路中T端口与P端口之间是一一对应的。从设计原理上来说，相同频段的四个支持接收功能的T端口必须分别连接4个P端口，从而确保能够实现下行四路接收功能。
其中，本申请中的P端口英文全称是Port(极化)端口，本申请中用于多路选择开关中连接天线的端口的称谓，T端口英文全称是Throw(投、掷)，本申请中用于多路选择开关中连接射频电路的端口的称谓，如4P4T开关。
其中，由于n个T端口中的只有1个第一T端口全连接所述4个P端口，第二T端口中每个端口 只连接2支天线做接收使用，相对于4个T端口中每个T端口均全连接4个P端口的方式，可减少4PnT开关内置场效应管数量/体积/成本，相对于第二T端口中每个端口仅连接单个P端口的最简化状态，在功能上拓展支持FDD制式下的SRS功能和下行4X4MIMO的功能的同步工作，从而提升适用性。下面对该部分做详细说明。
举例来说，假设n＝4，所述多路选择开关由场效应管构成，若该4个T端口中每个T端口均全连接4个P端口，则如图2所示的多路选择开关的示例结构图，该多路选择开关的场效应管的数量为4+4*4*3+4＝56；若该4个T端口中仅有1个T端口全连接4个P端口，其余每个T端口连接2个P端口，则如图3所示的多路选择开关的示例结构图，该多路选择开关的场效应管的数量为4+(1*4+(4-1)*2)*3+4＝38。
又举例来说，假设n＝5，所述多路选择开关由场效应管构成，若该5个T端口中每个T端口均全连接4个P端口，则该多路选择开关的场效应管的数量为5+5*4*3+4＝69；若该5个T端口中仅有1个T端口全连接4个P端口，其余每个T端口连接2个P端口，则该多路选择开关的场效应管的数量为5+(1*4+(5-1)*2)*3+4＝45。
由此可见，通过限定T端口中全连接4个P端口的T端口的数量，可以有效减少电子设备射频系统的开关数量。也就是说，该全连接型T端口的数量对射频系统的性能有着较大影响。
可见，本申请示例中，电子设备包括天线系统、射频电路和多路选择开关，该天线系统具体包括4支天线，多路选择开关包括n个T端口和4个P端口，且该多路选择开关连接所述射频电路和所述天线系统，由于该多路选择开关的第二T端口仅需要连接2个P端口即可实现在FDD制式中的预设功能，相对于所有T端口全连接的开关来说，可以有效较低开关数量，从而降低射频链路开关插损，提高电子设备的射频的指标性能，且相对于第二T端口仅连接单个P端口来说，能够支持FDD制式下的预设功能，即拓展了电子设备的功能性。
在一个可能的示例中，n小于等于10；所述4个P端口中的每个P端口连接对应的天线；所述4个P端口中的每个P端口连接对应的天线；所述第一T端口支持信号收发功能，所述第二T端口仅支持信号接收功能。
其中，由于所述电子设备支持单发模式，因此在第五代移动通信新空口5G NR系统中该电子设备最多支持双频单上行链路UL2*2MIMO下行链路DL4*4MIMO，即逻辑上包括8路信号接收通路和2路信号发射通路，因此最多对应10个T端口，故而n的取值小于等于10。
其中，所述支持收发功能是指支持信号接收功能和信号发射功能。
可见，本示例中，由于多路选择开关具体由m个第一T端口和n-m个第二T端口组成，故而该多路选择开关相对于全部T端口全连接P端口的形态减少了开关数量，能够减少电子设备射频系统的开关数量，可以减少路径损耗，从而提升发射功率和接收灵敏度，改善5G NR中数据传输速率，改善手机上下行覆盖范围，减少功耗和成本。
在一个可能的示例中，所述单发模式包括单频单发模式和双频单发模式。
其中，所述单频单发模式是指电子设备最大能力可以支持单频段、UL单发射通路或者DL4接收通路的工作模式，双频单发模式是指电子设备最大能力可以支持双频段、UL单发射通路或者DL4接收通路的工作模式。
在一个可能的示例中，所述多路切换开关包括n个第一开关管、(m*4+(n-m)*2)*3个第二开关管、4个第三开关管，所述第一开关管对应所述T端口，所述第三开关管对应所述P端口，每3个所述第二开关管串联构成所述T端口和所述P端口之间的开关子单元，所述开关子单元的两端的2个第二开关管分别连接1个T端口和1个P端口，所述开关子单元的中间的第二开关管接地，每个第一开关管、每个所述第二开关管、所述每个第三开关管的门极均连接开关控制芯片。
具体实现中，由于开关子单元断开时，若没有接地，寄生参数对多路选择开关中其他导通的端口性能影响太大，所以这里将开关子单元设置为3个开关管，其中，3个开关管可以共源极连接，断开时， 两侧的2个开关管都断开，中间的开关管接地导通。
其中，本申请实施例所描述的多路选择开关中T端口与P端口之间的连接、全连接等概念，均是指多路选择开关中的T端口通过所述开关子单元连接P端口的状态。所述第一、第二、第三开关管可以是金属氧化物半导体MOS管等，电子设备可以通过开关控制芯片的端口连接第一第二第三开关管中每个MOS管的门极，开关控制芯片可以采用移动产业处理器接口MIPI接口，电子设备控制该开关控制芯片的驱动端口的信号即可控制任意T端口与P端口之间的连接状态。
可见，本示例中，由于多路选择开关的开关子单元包括三个第二开关管，中间的第二开关管接地，从而可以在断路状态下避免当前开关管的寄生参数对其他导通端口性能的影响，提高开关控制稳定性。

请参阅图9，图9是本申请实施例提供了一种功能控制方法的流程示意图，应用于电子设备，所述电子设备包括天线系统、射频电路以及多路选择开关，所述多路选择开关包括n个T端口和4个P端口，所述n个T端口包括m个第一T端口和n-m第二T端口，所述电子设备支持单发模式，每个第一T端口全连接所述4个P端口，每个第二T端口连接所述4个P端口中的2个P端口，支持相同频段的信号接收功能的多个第二T端口所连接的P端口覆盖所述4个P端口，且处于信号接收状态的所述4个T端口中每个T端口所连接的P端口互不相同，m等于1或2或4，n为大于或等于4的整数；所述方法包括：
S901，所述电子设备确定执行预设功能，所述预设功能包括第一功能和第二功能，所述第一功能为支持通过探测参考信号SRS在发射天线间轮发，发送4端口SRS的功能，所述第二功能为支持所述4支天线同时接收数据的功能；
S902，所述电子设备在启用所述第一功能的过程中，根据所述第一功能当前占用的P端口调整所述第二功能当前占用的4个T端口中3个T端口与所述4个P端口中3个P端口之间的匹配状态，所述3个T端口为所述4个T端口中除所述第一功能当前使用的单个第一T端口之外的3个T端口，所述3个P端口为所述所述4个P端口除被所述第一功能当前使用的单个第一T端口占用的P端口之外的3个P端口。
其中，电子设备执行第一第二功能，能够满足5G NR FDD制式系统中功能要求。
可见，本申请实施例中，电子设备能够通过基于多路选择开关构建的射频系统实现5G NR FDD制式系统中的预设功能，且由于多路选择开关结构简化，控制高效，有利于提高电子设备完成预设功能的实时性和效率。
下面以如图4B所示的多路切换开关为例，详细说明本申请实施例中的T端口和P端口之间的切换过程。假设该多路切换开关初始状态下4个T端口平行连接4个P端口，即T1连接P1，T2连接P2，T3连接P3，T4连接P4，4个P端口分别连接4支天线，当电子设备确定启用预设功能时，则电子设备在启用SRS的过程中，电子设备在第一探测周期可以通过T1与P1通路(该通路预先导通作为接收通路使用)收发信号以进行信号接收和第一天线的信道质量探测，第一探测周期由于T2、T3以及T4对应的P端口均未被占用，故而本周期内不发生切换。
其次，电子设备在第二探测周期可以控制T1与P2导通发射信号以进行信号接收第二天线的信道探测，此周期原T2对应的P2被占用，则为了维持T2的信号接收功能，T2需要切换连接至P1。
再次，电子设备在第三探测周期可以控制T1与P3导通收发信号以进行信号接收和第三天线信道探测，此周期原T3对应的P3被占用，则为了维持T3的信号接收功能，T3需要切换连接至P2。
最后，电子设备在第四探测周期可以控制T1与P4导通收发信号以进行信号接收和第四天线信道探测，此周期原T4对应的P4被占用，则为了维持T4的信号接收功能，T4需要切换连接至P3。
至此，电子设备完成SRS探测过程，且T1连接P4进行信号接收，T2连接P1进行信号接收，T3连接P2进行信号接收，T4连接P3进行信号接收。
请参阅图10，图10是本申请实施例提供了一种射频系统的结构示意图，该射频系统包括天线系统、射频电路以及上述任一实施例所述的多路选择开关；
所述多路选择开关用于连接所述射频电路和所述天线系统以实现所述电子设备在频分复用FDD制式中的预设功能，所述预设功能包括第一功能和第二功能，所述第一功能为支持通过探测参考信号SRS在发射天线间轮发，发送4端口SRS的功能，所述第二功能为支持所述4支天线同时接收数据的功能。
请参阅图11，图11是本申请实施例提供了一种无线通信设备的结构示意图，该无线通信设备包括天线系统、射频电路以及上述任一实施例所述的多路选择开关；

所述无线通信设备至少包括以下任意一种：电子设备、基站。
此外，如图12所示，本申请实施例所描述的天线系统中的4支天线还可以被该电子设备的无线充电接收器所复用，具体的，该无线充电接收器包括接收天线、接收控制电路，该接收天线与无线充电发射器的发射天线匹配(频率相同或相近情况下谐振，以辐射性谐振磁耦合的方式，将能量通过无线传送的方式传输)，接收控制电路通过环形阵列天线将能量转变为直流电DC输出给电池充电，接收控制电路能够动态调整该环形阵列天线的频率，并使之与无线充电发射器的发射天线的频率匹配，以实现配对充电，或者，实时与无线充电发射器进行频率变化范围交互，以实现“专属加密”无线充电模式。
其中，所述接收天线可以是由4支天线中的至少1支天线所组成的天线(多支情况下天线与天线之间通过开关选通)。
例如：如图13所示，该接收天线为由上述4支天线构成的环形阵列天线，4支天线具体包括天线1、天线2、天线3、天线4，其中天线1和天线4支持LTE和5G NR频段，天线2和天线3仅支持5G NR频段，天线1的端口和天线4的端口作为该环形阵列天线的端口，其中相邻天线之间通过具有隔离功能的选通电路170连接，该选通电路170包括隔离片171和开关172，隔离片171为导体，开关172还连 接控制器，电子设备在无线充电模式下可以连通每个选通电路170的开关172，以形成环形阵列天线接收能量。通过在天线间加入隔离片171，该选通电路170一方面降低了电子设备在正常通信模式下的多天线间的互耦性，提升了多天线间的隔离度，优化了天线性能，另一方面通过开关171能够将多天线串联形成环形阵列天线，以便于更好的匹配发射天线以传输能量，此外，由于天线1和天线4能力强于天线2和天线3，如此设置的环形阵列天线可以尽可能减少能量传输损耗。
以上是本申请实施例的实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请实施例原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
