技术领域
本公开涉及通信技术领域，尤其涉及一种天线控制方法和折叠屏终端。
背景技术
多天线MIMO(Multiple-Input Multiple-Output，多输入多输出)技术指在发射端和接收端分别使用多个发射天线和接收天线，使信号通过发射端与接收端的多个天线传送和接收，从而改善通信质量。它能充分利用空间资源，通过多个天线实现多发多收，在不增加频谱资源和天线发射功率的情况下，可以成倍的提高系统信道容量，是第四代(Fourth Generation(4G))和未来第五代(Fifth generation(5G))移动通信技术中的重要技术。
相关折叠屏终端可以通过展开、折叠使得调整屏幕显示面积。配备有折叠屏的折叠屏终端，体积比于不配备折叠屏的移终端更大，所以折叠屏终端可以设置更多MIMO天线。
在折叠屏终端处于展开状态时，分布在终端上的多个天线由于空间距离较大，可以很好的实现多天线MIMO功能，使MIMO性能达到最优。但折叠屏终端处于折叠状态时，MIMO天线由于相互之间的空间距离减小，将导致MIMO性能的下降，且折叠状态下的MIMO天线的耗电与展开状态下的MIMO天线的耗电相当，因此折叠屏终端处于折叠状态时，MIMO性能和功耗的比值相比于展开状态时小，导致了较多不必要的电能损耗。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
本公开实施例提供一种天线控制方法，应用于折叠屏终端，如图1所示，折叠屏终端100可以包括可相对折叠设置的第一屏幕模组111和第二屏幕模组112，折叠屏终端100还可以包括至少一个天线组120，每一天线组120可以包括设置于第一屏幕模组111的第一天线121和设置于第二屏幕模组112的第二天线122。其中，如图1中所示例的，折叠屏终端100上可以包括四个天线组120，为简化标注示意，图1中仅对其中一个天线组120及其所包括的第一天线121和第二天线122进行标注；这里，天线1和天线2分别为第一天线121和第二天线122，组成一个天线组120；天线3和天线4分别为第一天线121和第二天线122，组成一个天线组120；天线5和天线6分别为第一天线121和第二天线122，组成一个天线组120；天线7和天线8分别为 第一天线121和第二天线122，组成一个天线组120。可选地，如图1所示，本公开实施例中，针对每一天线组120，设置于第一屏幕模组111上的第一天线121与设置于第二屏幕模组112上的第二天线122，关于第一屏幕模组111和第二屏幕模组112相对折叠的折叠轴线对称设置，可以理解地，在第一屏幕模组111与第二屏幕模组112贴合设置时，每一天线组120中的第一天线121与第二天线122处于相对位置。
请参见图3，其示出的是本公开实施例提供的天线控制方法的流程示意图，在本公开实施例中，该天线控制方法可以包括以下步骤：
步骤301，获取第一屏幕模组与第二屏幕模组之间的折叠状态信息。
本公开实施例中，在折叠屏终端启用多个MIMO天线工作，即折叠屏终端使用多个天线同时进行通信时，对第一屏幕模组与第二屏幕模组之间的折叠或展开状态进行检测，获取折叠状态信息，以便于后续至少一个天线组中的天线进行调节控制，确保MIMO天线性能并提高电能利用率。可选地，折叠状态信息可以包括第一屏幕模组与第二屏幕模组之间的相对角度以及第一屏幕模组与第二屏幕模组之间的相对距离等信息中的至少一个。
步骤302，针对于每一天线组，根据折叠状态信息，确定天线组的相关性系数。
本步骤中，可以基于步骤301获取的第一屏幕模组与第二屏幕模组之间的折叠状态信息，分别确定每一天线组的相关性系数，即可以确定各天线组的相关性系数，以便后续步骤基于各天线组的相关性系数对各天线组中的天线进行调节控制，确保MIMO天线性能并提高电能利用率。
可选地，在本公开实施例中，该相关性系数可以包括包络相关系数和信号相关系数中的至少一个，包络相关系数用于表征从不同的天线接收到的复信号之间的相关性，包络相关系数用于表征接收到不同信号幅值之间的相关性。
步骤303，若相关性系数的数值高于预设阈值，则控制天线组中的目标天线调节至非工作状态，目标天线为第一天线和第二天线中的一个。
本步骤中，基于步骤302确定的每一天线组的相关性系数，针对于每一天线组，若检测到天线组的相关性系数的数值高于预设阈值，表示天线组中 的天线之间的空间距离较小，MIMO性能较低，则将天线组中第一天线和第二天线中的一个(即目标天线)调节至非工作状态，以此保证天线组的MIMO天线性能，并且，通过减少了天线组中的目标天线的电能损耗，提高了电能利用率。
可选地，在本公开实施例中，预设阈值可以为天线组达到最低MIMO性能时所对应的相关性系数的数值。
本公开实施例中，通过根据第一屏幕模组与第二屏幕模组之间的折叠状态信息，确定每一天线组的相关性系数，然后根据每一天线组的相关性系数的数值，对天线组中的天线进行调节控制，从而能够确保MIMO天线性能并能够避免不必要的电能消耗，提高电能利用率，达到省电效果。
可选地，在本公开一些实施例中，如图1所示，折叠屏终端100还可以包括折叠部件130，该第一屏幕模组111与第二屏幕模组112通过折叠部件130连接，并通过该折叠部件130实现第一屏幕模组111与第二屏幕模组112之间的折叠设置或展开设置。也就是说，可选地，步骤301，获取第一屏幕模组与第二屏幕模组之间的折叠状态信息，可以包括以下步骤：检测连接第一屏幕模组与第二屏幕模组的折叠部件的折叠角度；根据折叠角度，确定折叠状态信息。本公开实施例中，由于第一屏幕模组与第二屏幕模组之间的折叠或展开是通过折叠部件的折叠实现，即第一屏幕模组与第二屏幕模组之间的折叠状态信息与该折叠部件的折叠角度相关，因此，可以通过检测折叠部件的折叠角度，基于折叠角度与折叠状态信息之间的对应关系，确定第一屏幕模组与第二屏幕模组之间的折叠状态信息。可选地，如图2所示，折叠屏终端100上可以设置折叠状态传感器150，用于感知折叠部件的折叠角度，获取第一屏幕模组与第二屏幕模组之间的折叠状态，该折叠状态传感器150可以为角度传感器，本公开实施例中，可以通过该折叠状态传感器150检测折叠部件130的折叠角度。
在一示例中，该折叠状态信息可以为第一屏幕模组与第二屏幕模组之间的相对角度，则在检测到折叠部件的折叠角度后，可以将折叠角度确定为第一屏幕模组与第二屏幕模组之间的相对角度；在另一示例中，该折叠状态信息可以为第一屏幕模组与第二屏幕模组之间的相对距离，则在检测到折叠部 件的折叠角度后，可以基于折叠角度与相对距离之间的对应关系，确定第一屏幕模组与第二屏幕模组之间的相对距离，这里为实现检测确定，可以以第一屏幕模组和第二屏幕模组上相对应的预定位置作为相对距离的检测点，以检测点之间的距离作为相对距离。
可以理解的是，本公开实施例中，对于折叠状态信息的获取方式并不局限于此，例如，也可以通过折叠屏终端上设置一距离传感器，利用该距离传感器直接检测第一屏幕模组的第一端面与第二屏幕模组的第二端面之间的相对距离，从而获取第一屏幕模组与第二屏幕模组之间的折叠状态信息，其中，在第一屏幕模组与第二屏幕模组处于折叠状态时，第一屏幕模组的第一端面与第二屏幕模组的第二端面贴合。
在本公开一些可选的实施例中，步骤302，针对于每一天线组，根据折叠状态信息，确定天线组的相关性系数，可以包括：针对于每一天线组，根据预设的折叠状态信息与天线组的相关性系数之间的对应关系，确定与折叠状态信息匹配的相关性系数。本公开实施例中，可以预先检测记录各天线组在不同折叠状态信息下的相关性系数，然后设置折叠状态信息与天线组的相关性系数之间的对应关系，这样，在步骤301获取到折叠状态信息之后，即可以基于折叠状态信息与天线组的相关性系数之间的对应关系，获得各天线组的相关性系数，以便后续步骤基于各天线组的相关性系数对各天线组中的天线进行调节控制，确保MIMO天线性能并提高电能利用率。
可选地，本公开实施例中，可以采用映射表形式记录折叠状态信息与天线组的相关性系数之间的对应关系，即可以预先检测记录各天线组在不同折叠状态信息下的相关性系数，然后设置映射表“折叠状态信息—相关性系数表”，也就是说，针对于每一天线组，根据预设的折叠状态信息与天线组的相关性系数之间的对应关系，确定与折叠状态信息匹配的相关性系数，可以包括：针对每一天线组，在映射表中，查找与折叠状态信息对应的相关性系数。
可选地，在本公开一些实施例中，如图2所示，折叠屏终端100还可以包括：至少一个MIMO射频通路140，其中每一MIMO射频通路140与一个天线连接，通过天线及其对应连接的MIMO射频通路140，能够实现MIMO下行信号的接收。如图2所示例的，至少一个MIMO射频通路140可以包括 MIMO射频通路1、MIMO射频通路2、MIMO射频通路3、MIMO射频通路4……MIMO射频通路N，其中，MIMO射频通路1与天线1连接，MIMO射频通路2与天线2连接，MIMO射频通路3与天线3连接，MIMO射频通路4与天线4连接，……，MIMO射频通路N与天线N连接。这里，通过控制天线及其连接的MIMO射频通路，可以实现控制天线处于工作状态或非工作状态，也就是说，在本公开实施例中，步骤303，若相关性系数的数值高于预设阈值，则控制天线组中的目标天线调节至非工作状态，可以包括：若相关性系数的数值高于预设阈值，则控制天线组中的目标天线关闭，并控制与目标天线连接的MIMO射频通路断开。本公开实施例中，针对于每一天线组，若检测到天线组的相关性系数的数值高于预设阈值，则控制天线组中第一天线和第二天线中的一个(即目标天线)关闭，并控制与其连接MIMO射频通路断开，以此保证天线组的MIMO天线性能，并且，通过减少了天线组中的目标天线的电能损耗，提高了电能利用率。
可选地，如图2所示，为便于实现折叠屏终端100还可以包括处理单元160，该处理单元160与每一MIMO射频通路140连接，控制每一天线的开启和关闭，以及每一MIMO射频通路的导通和断开；此外，处理单元160可以与折叠状态传感器150连接，用于控制折叠状态传感器工作，并获取折叠状态传感器中检测到的折叠状态信息；处理单元160还可以用于存储天线组在不同折叠状态信息时的相关性系数，即存储折叠状态信息与天线组的相关性系数之间的对应关系，并储存相关性系数阈值信息(即预设阈值)。也就是说，本公开实施例中，可以通过该处理单元160针对每一天线组，将天线组的相关性系数的数值与预设阈值进行比较，并在天线组的相关性系数的数值高于预设阈值，控制天线组中的目标天线关闭，并控制与目标天线连接的MIMO射频通路断开。较优地，该处理单元160可以为CPU(Central Processing Unit，中央处理器)或储存器。
另外，在本公开一些可选的实施例中，每一MIMO射频通路140可以包括滤波器，LNA(Low Noise Amplifier，低噪声放大器)，以及解调器。
本公开实施例提供的天线控制方法，通过根据第一屏幕模组与第二屏幕模组之间的折叠状态信息，确定每一天线组的相关性系数，然后根据每一天 线组的相关性系数的数值，对天线组中的天线进行调节控制，从而能够确保MIMO天线性能并能够避免不必要的电能消耗，提高电能利用率，达到省电效果。
