技术领域
本公开涉及通信技术领域，尤其涉及一种发射天线的切换方法及终端设备。
背景技术
第五代(5th generation，5G)通信系统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)。当终端设备在NSA网络下与基站进行通信时，若终端设备采用长期演进(Long Term Evolution，LTE)与5G新无线(New Radio，NR)的双连接的方式进行通信，则需要LTE频段与NR频段能够同时工作。
由于终端设备需要进行LTE频段的发射天线切换，用于优化LTE频段信令连接时的信号质量，同时，由于终端设备需要进行NR频段的探测参考信号(Sounding Reference Signal，SRS)天线轮发，以让基站获知终端设备天线的信道质量，终端设备在进行SRS天线轮发时也需要进行发射天线切换。因此，LTE频段和NR频段在发射天线切换过程中存在冲突，从而影响通信质量的问题，也就是说，当终端设备同时使用两种网络时，会存在发射天线切换时的冲突问题，影响通信质量。
发明内容
本公开实施例提供一种发射天线的切换方法及终端设备，以解决终端设备同时使用两种网络时发射天线切换过程中存在冲突，从而影响通信质量的问题。
为解决上述技术问题，本公开是这样实现的：
第一方面，本公开实施例提供了一种发射天线的切换方法，应用于终端设备，包括：
在终端设备处于双网络连接态时，确定用于传输控制面数据的第一网络、以及仅用于传输用户面数据的第二网络；

第二方面，本公开实施例还提供一种终端设备，包括：
第一确定模块，用于在终端设备处于双网络连接态时，确定用于传输控制面数据的第一网络、以及仅用于传输用户面数据的第二网络；
第二确定模块，用于在接收到探测参考信号SRS轮发请求的情况下，确定所述第二网络的工作模式；
第三确定模块，用于根据所述第二网络的工作模式，确定所述第一网络与所述第二网络进行发射天线切换的优先级顺序；

第三方面，本公开实施例还提供一种终端设备，包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现上述发射天线的切换方法的步骤。
第四方面，本公开实施例还提供一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现上述发射天线的切换方法的步骤。
在本公开实施例中，在终端设备处于双网络连接态时，确定用于传输控制面数据的第一网络、以及仅用于传输用户面数据的第二网络；在接收到探测参考信号SRS轮发请求的情况下，确定所述第二网络的工作模式；根据所述第二网络的工作模式，确定所述第一网络与所述第二网络进行发射天线切换的优先级顺序；根据所述优先级顺序，在所述第一网络上进行SRS天线轮 发。这样，通过确定第一网络与第二网络进行发射天线切换的优先级顺序，来进行SRS天线轮发，从而避免在发射天线切换过程中第一网络与第二网络对天线资源的争抢冲突，改善通信质量。

具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的发射天线的切换方法的流程图之一，如图1所示，本公开实施例提供一种发射天线的切换方法，应用于终端设备，包括以下步骤：
步骤101、在终端设备处于双网络连接态时，确定用于传输控制面数据的第一网络、以及仅用于传输用户面数据的第二网络。
终端设备同时连接第一网络和第二网络，第一网络用于传输控制面数据，控制面数据用于保证终端设备与基站的稳定连接，第一网络还用于传输用户面数据。第二网络不传输控制面数据，仅用于传输用户面数据。
本实施例可应用于NSA模式下的网络架构选项(Architecture Option)4/4a，在此网络架构选项中，第一网络为NR网络，第二网络为LTE网络。终端设备与NR网络(即第一网络)之间有控制面和数据面的数据传输，终端设备与LTE网络(即第二网络)之间仅有用户面的数据传输。
步骤102、在接收到探测参考信号SRS轮发请求的情况下，确定所述第二网络的工作模式。
终端设备在接收到SRS轮发请求时，终端设备需要进行SRS天线轮发，SRS天线轮发是为了便于基站获知终端设备天线(具体为支持第一网络的发射天线)的信道质量，在进行SRS天线轮发时，轮发的天线均向基站发送SRS。在进行SRS天线轮发时，是通过第一网络的发射天线轮发SRS信号，来获取第一网络的接收天线性能(接收和发射同频)。即，通过第一网络的发射天线获取其接收天线的信道质量。
第二网络的工作模式包括时分双工(Time Division Duplexing，TDD)和频分双工(Frequency Division Duplexing，FDD)。TDD工作模式下，第二网络的上下行链路使用不同的时隙来与终端设备进行通信。FDD工作模式下，第二网络的上下行链路分别使用不同的频率与终端设备进行通信。在接收到探测参考信号SRS轮发请求的情况下，确定所述第二网络是采用的TDD工作模式，还是FDD工作模式。
步骤103、根据所述第二网络的工作模式，确定所述第一网络与所述第二网络进行发射天线切换的优先级顺序。
第二网络在不同的工作模式下，第一网络与第二网络进行发射天线切换的优先级顺序不同。例如，在所述第二网络为TDD工作模式的情况下，可设置所述第一网络的优先级低于所述第二网络的优先级，或者在所述第二网络为时分双工FDD工作模式的情况下，可设置所述第一网络的优先级高于所述第二网络的优先级。
步骤104、根据所述优先级顺序，在所述第一网络上进行SRS天线轮发。
具体的，根据所述第二网络的工作模式，来确定所述第一网络与所述第二网络进行发射天线切换的优先级顺序，从而确定在所述第一网络上进行SRS天线轮发的时机，或者关闭第二网络的数据发射，然后终端设备在第一网络上进行SRS天线轮发，以避免第二网络在第一网络进行SRS天线轮发时，与第一网络争抢天线资源，从而影响通信质量的问题。
本公开实施例中，上述终端设备可以为手机、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。
本公开实施例的发射天线的切换方法，在终端设备处于双网络连接态时，确定用于传输控制面数据的第一网络、以及仅用于传输用户面数据的第二网络；在接收到探测参考信号SRS轮发请求的情况下，确定所述第二网络的工作模式；根据所述第二网络的工作模式，确定所述第一网络与所述第二网络进行发射天线切换的优先级顺序；根据所述优先级顺序，在所述第一网络上进行SRS天线轮发。这样，通过确定第一网络与第二网络进行发射天线切换的优先级顺序，来进行SRS天线轮发，从而避免在发射天线切换过程中第一网络与第二网络对天线资源的争抢冲突，改善通信质量。
进一步的，在本公开一个实施例中，如图2a所示，上述步骤103、据所述第二网络的工作模式，确定所述第一网络与所述第二网络进行发射天线切换的优先级顺序，包括：
步骤1031、在所述第二网络为TDD工作模式的情况下，确定所述第一网络的优先级低于所述第二网络的优先级；
步骤104、根据所述优先级顺序，在所述第一网络上进行SRS天线轮发，包括：
步骤1041、在所述第二网络的接收时隙内，在所述第一网络上进行SRS天线轮发。
具体的，当第二网络工作在TDD工作模式下时，由于在第二网络的接收时隙内接收数据，此时，在第二网络的接收时隙内进行SRS天线轮发并不会影响第二网络的数据发射，即在第二网络的接收时隙内进行SRS天线轮发不 会与第二网络的发射天线的使用相冲突。
如图2b所示，第一网络为NR网络，第二网络为LTE网络。NR频段上的SRS天线轮发在LTE频段的接收时隙内进行。
在本实施例中，第一网络进行SRS天线轮发时，可采用天线集合进行SRS天线轮发，天线集合包括第二网络在发送时隙时所使用的天线。
本实施例中，在所述第二网络为TDD工作模式的情况下，在所述第二网络的接收时隙内，在所述第一网络上进行SRS天线轮发，可优先保证第一网络的正常功能需求(即第一网络的SRS天线轮发需求)，有效避免了第一网络和第二网络争抢发射天线的问题，改善了通信质量。并且，终端设备是在第二网络的接收时隙内进行SRS天线轮发，不会对第二网络的数据发射产生影响，保证了第二网络在数据发射时的信号质量。
进一步的，在本公开另一个实施例中，如图3a所示，上述步骤103、根据所述第二网络的工作模式，确定所述第一网络与所述第二网络进行发射天线切换的优先级顺序，包括：
步骤1032、在所述第二网络为时分双工FDD工作模式的情况下，确定所述第一网络的优先级高于所述第二网络的优先级。
步骤104、根据所述优先级顺序，在所述第一网络上进行SRS天线轮发，包括：
步骤1042、停止通过所述第二网络进行数据发射。
具体的，停止通过第二网络进行数据发射可以理解为：通过软件控制停止发送第二网络的数据，但是第二网络数据发射的物理通路是连接的；或者通过软件控制停止发送第二网络的数据，并且，第二网络数据发射的物理通路是断开的。第二网络的数据发射在关闭的情况下，可认为第二网络停止使用发射天线。第二网络为FDD工作模式时，第二网络的数据发射和数据接收采用不同的频率，关闭第二网络的数据发射对第二网络的数据接收产生的影响较小，仍旧可以保证第二网络的下行通信能力。
在所述第二网络为FDD工作模式的情况下，停止通过所述第二网络进行数据发射，由于第二网络并未使用发射天线，这样，可以避免第一网络在进行SRS轮发时，与第二网络使用的发射天线之间产生冲突。
在本公开一个实施例中，步骤1032、所述停止通过所述第二网络进行数据发射，包括：
确定所述SRS天线轮发的时隙或符号周期；
在所述时隙或所述符号周期内停止通过所述第二网络进行数据发射。
图3b所示为NR频段1T4R SRS天线轮发的时频结构，该时频结构中，NR频段1T4R SRS天线轮发占用两个时隙；SRS信号仅在特定时隙的特定符号内发送，SRS最多在时隙的最后6个符号内发送；大部分时隙及其符号用于传输上下行的控制信号和数据信号等。
在关闭第二网络的数据发射时，可在SRS天线轮发的时隙内关闭第二网络的数据发射，例如，若SRS天线轮发时的SRS信号在第一时隙内发送，那么在第一时隙内关闭第二网络的数据发射；若SRS天线轮发时的SRS信号在时隙的最后6个符号内发送，那么在时隙的最后6个符号内关闭第二网络的数据发射。
在本实施例中，确定SRS天线轮发的时隙或符号周期，在所述时隙或所述符号周期内停止通过所述第二网络进行数据发射。这样，可以避免第一网络在进行SRS轮发时，与第二网络使用的发射天线之间产生冲突，可优先保证第一网络的正常功能需求(即第一网络的SRS天线轮发需求)，有效避免了第一网络和第二网络争抢发射天线的问题，改善了通信质量。
以目前3GPP定义，NR频段以30KHz的子载波间隔为例，一个时隙包含14个符号，其时间为0.5ms，即1个符号的时间约为35.7us，SRS最多在时隙的最后6个符号内发送；在时域上，LTE频段的资源调度周期为1ms，若在SRS天线轮发的符号周期内关闭LTE的数据发射，由于SRS信号发送占用的时间占LTE资源调度周期的比例很小，因此，在SRS天线轮发的符号周期内关闭LTE的数据发射，对LTE发射通信的影响很小，可忽略不计。
步骤1043、在所述第一网络上利用第一天线集合进行SRS天线轮发，其中，所述第一天线集合包括所述第二网络所使用的发射天线。
具体的，由于关闭了第二网络的数据发射，第一网络进行SRS天线轮发时，可使用第二网络所使用的发射天线，这样，可以避免第一网络在进行SRS轮发时，与第二网络使用的发射天线之间产生冲突。可优先保证第一网络的 正常功能需求(即第一网络的SRS天线轮发需求)，有效避免了第一网络和第二网络争抢发射天线的问题，改善了通信质量。
进一步的，为了使得终端设备在第一网络上进行SRS天线轮发时可使用更多的天线，所述在所述时隙或所述符号周期内停止通过所述第二网络进行数据发射，包括：
在所述时隙或所述符号周期内停止通过所述第二网络进行数据发射和数据接收；
在所述第一网络上利用第一天线集合进行SRS天线轮发，包括：
在所述第一网络上利用第二天线集合进行SRS天线轮发，其中，所述第二天线集合包括所述第二网络所使用的接收天线和所述第一天线集合中的天线。
在本实施例中，在所述时隙或所述符号周期内，不仅关闭所述第二网络的数据发射，还关闭第二网络的数据接收，这样，不仅第二网络用于数据发射的天线可以被第一网络在进行SRS天线轮发时使用，而且第二网络用于数据接收的天线也可以被第一网络在进行SRS天线轮发时使用，使得第一网络在进行SRS天线轮发时可切换的天线更多。
由于关闭了第二网络的数据发射和数据接收，第一网络进行SRS天线轮发时，可使用第二网络所使用的发射天线和接收天线，这样，在避免第一网络在进行SRS轮发时，与第二网络使用的发射天线之间产生冲突的同时，还能使得第一网络在进行SRS天线轮发时可切换的天线更多。
如图4所示，终端设备的天线切换流程如下：
步骤11、建立与基站的通信连接；
步骤12、检测终端设备的工作模式，是否工作在LTE网络和NR网络的双网络模式下；
步骤13、终端设备工作在NSA模式下；
步骤14、检测当前NSA模式的网络架构选项，网络架构为Option4/4A；
步骤15、检测LTE频段是否为TDD系统；若LTE频段为TDD系统，转步骤151执行；若LTE频段不为TDD系统，转步骤16执行；
步骤151、NR频段仅在LTE的Rx(即接收)时隙内进行SRS天线轮发；
步骤16、检测是否需要进行NR频段的SRS天线轮发；若是，转步骤17执行，若否，结束NSA工作模式；
步骤17、在SRS天线轮发的时隙或符号周期内关闭LTE发射或关闭整个LTE的通信，同时进行NR频段SRS轮发。
