具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
本申请实施例的技术方案可以应用于近距离无线通信，在发送端设备与接收端设备的天线靠近时，即可以实现发送端设备与接收端设备之间的非接触式点对点数据传输和通信，同时，可以基于高载波频率(例如，60GHz)实现高速的数据无线传输。
下面结合图1，对近距离无线通信方式进行介绍。
如图1所示，近距离无线通信***100包括发送端设备110和接收端设备120。发送端设备110与接收端设备120可以现实非接触式的高速数据传输，可选地，在发送端设备110的集成电路(Integrated Circuit，IC)芯片内封装极高频(Extremely high frequency，EHF)天线，从而，发送端设备110可以基于高载波频率(例如，60GHz)实现高速的数据无线传输(例如，最高可达6GB/s的传输速度)。可选地，接收端设备120的IC芯片内也可以封装EHF天线，从而，可以实现发送端设备110与接收端设备120之间的双向通信。可选地，发送端设备110与接收端设备120之间通过电磁信号实现数据的无线传输。
应理解，基于高载波频率的近距离无线通信具有低功耗、体积小、传输速率快、非接触传输等优点，还可以实现即插即用模块的功能，可以大幅提高的信号完整性，支持更灵活的***实现，降低待机功耗，增加带宽幅度与数据传输的安全性，兼容对高速视频信号的支持等特点。
现阶段，在基于高载波频率的近距离无线通信中，发送端设备与接收端设备之间的通信连接可能由于意外或者人为原因随时断开，从而中断正在传输的文件数据，且断开后再连接，又需重新传输这些中断了的文件数据，不 仅浪费资源，而且影响用户体验。
为了解决上述技术问题，本申请实施例提供了一种数据传输的方法，在基于高载波频率的近距离无线通信中，可以实现发送端设备与接收端设备之间的断点续传。
下面将结合附图，对本申请中的技术方案进行描述。
图2是根据本申请实施例的数据传输的方法200的示意性流程图。该方法200应用于如图1所示的近距离无线通信***100，在发送端设备向接收端设备发送待传输数据的过程。该方法200包括以下内容中的至少部分内容。
S210，在该发送端设备与该接收端设备之间被中断的近距离无线通信重新恢复之后，该发送端设备查询记录的传输信息，该传输信息用于指示该待传输数据中未完成传输的数据块。
应理解，高载波频率可以是能够实现高速的数据无线传输的载波频率。高载波频率可以是某个明确的载波频率，也可以是一个载波频段，例如30GHz-300GHz，本申请实施例对此不做具体限定。
优选地，该高载波频率为60GHz。
可选地，所述发送端设备包括内部封装有EHF天线的IC芯片。
例如，发送端设备包括独立的传输芯片，例如，该独立的传输芯片为内部封装有EHF天线的IC芯片，该独立的传输芯片的发射功率可以为60GHz的高频，从而，可以实现发送端设备与接收端设备之间的数据的快速传输(如，6GB/s的传输速度)。
具体地，该发送端设备根据记录表查询记录的传输信息，该记录表包括该待传输数据中未完成传输的数据块和/或该待传输数据中已经完成传输的数据块。
例如，该发送端设备可以查询针对该接收端设备的记录表，或者，该发送端设备可以查询与该接收端设备的标识对应的记录表，即，此时记录表仅记录该发送端设备向该接收端设备发送该待传输数据的传输信息，进而，查询所记录的传输信息。
又例如，该发送端设备可以查询当前保存的所有记录表，从而，确定针对该接收端设备的记录表，进而，查询所记录的传输信息。
应理解，该发送端设备在传输该待传输数据的过程中，建立与该接收端设备的标识对应的记录表，该发送端设备每向接收端设备发送完一个数据 块，即在记录表中记录相应的数据块发送完毕。因此，传输信息可以及时反映待传输数据中数据块的传输情况。
可选地，在该待传输数据包括至少一个数据块未完成传输时，发送端设备保存该记录表。在该待传输数据中的所有数据块都完成传输时，发送端设备放弃保存该记录表。因此，可以减少因保存记录表而产生的开销。
应理解，记录表中记录的传输信息可以是数据块的索引对应的传输信息，也可以是数据块的标识对应的传输信息，还可以是数据块的编号对应的传输信息，本申请实施例对比不作限定。
例如，如表1所示的记录表，发送端设备将待传输数据分为7个数据块，索引1-7分别对应7个数据块，发送端设备传输了数据块1、数据块2和数据块3之后，由于位置偏移或者人为移动而断开了发送端设备与接收端设备之间的近距离无线通信连接，中断了待传输数据的传输，发送端设备保存该记录表，在发送端设备与接收端设备之间的近距离无线通信连接重新连接之后，发送端设备查询该记录表，从而，可以确定需要继续传输数据块4、数据块5、数据块6和数据块7。
表1
索引 是否完成传输
1 是

4 否
5 否
6 否
7 否
又例如，如表2所示的记录表，发送端设备将待传输数据分为7个数据块，索引1-7分别对应7个数据块，发送端设备传输了所有7个数据块之后，发送端设备放弃保存该记录表。
表2
索引 是否完成传输

需要说明的是，在发送端设备向接收端设备发送待传输数据时，发送端设备或者接收端设备由于位置偏移或者人为原因而断开了发送端设备与接收端设备之间的近距离无线通信连接，从而，发送端设备中断了待传输数据的传输。
优选地，该待传输数据为大数据，例如，该传输数据所占用的比特数大于20GB。
可选地，发送端设备与接收端设备之间的近距离无线通信连接建立之后，彼此将各自的设备唯一标识符发送给对方，各自保存对端的设备唯一标识符。
可选地，唯一标识符可以是媒体接入控制(Media Access Control，MAC)地址，或者MAC地址加设备名称等字段的组合，或者其它方式。
需要说明的是，在本申请实施例中，该发送端设备在确定该待传输数据之后，可以将该待传输数据分割成若干数据块。例如，该发送端设备可以根据该发送端设备自身的传输速率和接收端设备的传输速率，将该待传输数据分割成若干数据块，并且，每个数据块的传输时间小于或等于预设时间，例如，该预设时间可以是1s。比如，发送端设备和/或接收端设备的无线传输速率为6G比特每秒，则每个数据块应小于或等于6G比特。
例如，该发送端设备可以基于传输芯片特性，以及所采用的无线通信协议确定自身的传输速率。该发送端设备可以基于所采用的无线通信协议确定接收端设备的传输速率。
应理解，发送端设备可以均匀地将待传输数据分割成若干数据块，也可以随机将待传输数据分割成若干数据块，本申请实施例对比不作限定。
可选地，在该发送端设备查询记录的传输信息之前，该发送端设备确定与该接收端设备之间存在中断了传输的待传输数据。
可选地，发送端设备可以通过确定是否存在与接收端设备的标识对应的传输信息来确定与接收端设备之间是否存在中断了传输的待传输数据。
例如，若该发送端设备确定存在与该接收端设备的标识对应的传输信息，该发送端设备确定与该接收端设备之间存在中断了传输的待传输数据。若该发送端设备确定不存在与该接收端设备的标识对应的传输信息，该发送端设备确定与该接收端设备之间不存在中断了传输的待传输数据。
可选地，该发送端设备也可以直接确定与该接收端设备之间是否存在中断了传输的待传输数据。例如，发送端设备接收到接收端设备反馈的未成功接收待传输数据的反馈消息，发送端设备确定与接收端设备之间存在中断了传输的待传输数据。又例如，发送端设备在未成功发送待传输数据时，可以产生指示未成功发送待传输数据的指示信息，从而，发送端设备可以根据该指示信息确定与接收端设备之间存在中断了传输的待传输数据。
S220，该发送端设备向该接收端设备发送该待传输数据中未完成传输的数据块。
需要说明的是，该接收端设备可以将该近距离无线通信被中断之前收到的数据块a保存下来，在该近距离无线通信重新恢复之后，该接收端设备收到数据块b，此时，该接收端设备可以将数据块a与数据块b合并，即可以获取完整的待传输数据。
还需要说明的是，在该发送端设备与该接收端设备之间被中断的近距离无线通信重新恢复之后，还可能面临被中断的风险，因此，在该近距离无线通信重新恢复之后，该发送端设备还需要实时更新记录表，即该发送端设备每向该接收端设备发送完一个数据块，就在记录表中记录相应的数据块发送完毕。
可选地，该发送端设备为无线充电底座，在该发送端设备与该接收端设备进行近距离无线通信的过程中，该发送端设备为接收端设备无线充电。
应理解，无线充电方式主要分为磁耦合(或电磁感应)、磁共振以及无线电波三种方式。目前，主流的无线充电标准包括QI标准、电源实物联盟(power matters alliance，PMA)标准、无线电源联盟(alliance for wireless power，A4WP)。QI标准和PMA标准均采用磁耦合方式进行无线充电。A4WP标准采用磁共振方式进行无线充电。
在一些实施例中，如图3所示，无线充电底座210建立与接收端设备220之间的近距离无线通信，与此同时，无线充电底座210对接收端设备220进行无线充电，在无线充电底座210与接收端设备220之间被中断的近距离无 线通信重新恢复之后，无线充电底座210与接收端设备220之间可以实现断点续传，电子设备230可以为无线充电底座210提供数据。接收端设备220可以是诸如手机、平板等具有无线充电以及无线传输功能的设备，电子设备230可以是具有数据处理和传输功能的设备，例如可以是计算机。
可选地，如图3所示，电子设备230可以同时作为无线充电底座210的电源提供设备，通过外部接口a同时为无线充电底座210提供电能和数据。
可选地，如图3所示，适配器240可以作为无线充电底座210的电源提供设备，通过外部接口b为无线充电底座210提供电能。
应理解，外部接口a与外部接口b可以是相同的接口，也可以是不同的接口。
具体地，如图3所示，电源提供设备通过外部接口连接无线充电底座210，无线充电底座210通过内部的无线发射电路211将电源提供设备的输出电流转换成电磁信号(或电磁波)进行发射。例如，该无线发射电路211可以将电源提供设备的输出电流转换成交流电，并通过发射线圈或发射天线(图中未示出)将该交流电转换成电磁信号。接收端设备220可以通过无线接收电路221接收无线发射电路211发射的电磁信号，并将该电磁信号转换成无线接收电路221的输出电流。例如，该无线接收电路221可以通过接收线圈或接收天线(图中未示出)将无线发射电路211发射的电磁信号转换成交流电，并对该交流电进行整流和/或滤波等操作，将该交流电转换成无线接收电路221的输出电压和输出电流。无线接收电路221的输出电压和输出电流即可实现对接收端设备220(接收端设备220的电池)充电。
与此同时，电子设备230可以通过外部接口a将待传输数据发送给无线充电底座210，无线充电底座210中的第一通信控制单元213控制第一无线传输芯片212将待传输数据传输至接收端设备220，接收端设备220可以通过第二通信控制单元223控制第二无线传输芯片222接收待传输数据。第一通信控制单元213例如可以包含微控制单元(Micro Control Unit，MCU)，该MCU可以总体控制无线充电底座210的无线充电过程，无线数据传输过程，以及通信过程。第二通信控制单元223例如可以是中央处理器(Central Processing Unit，CPU)，该CPU可以总体控制接收端设备220的无线充电过程，无线数据传输过程，以及通信过程。该第一传输芯片212和该第二传输芯片222例如可以是内部封装有EHF天线的IC芯片，其发射功率可以为 60GHz的高频。
需要说明的是，如图3所示，在无线充电底座210与接收端设备220之间被中断的近距离无线通信重新恢复之后，无线充电底座210可以通过第一通信控制单元213查询记录的传输信息，以及向接收端设备220发送该待传输数据中未完成传输的数据块。
应理解，无线充电底座210可以包括具体存储功能的只读存储器和/或随机存取存储器，从而，可以记录传输信息。
可选地，在如图3所示的实施例中，接收端设备220也可以通过第二通信控制单元223控制第二无线传输芯片222向无线充电底座210发送数据。也就是说，无线充电底座210与接收端设备220之间的近距离无线通信可以实现双向通信。
因此，在本申请实施例的数据传输的方法中，发送端设备与接收端设备之间被中断的近距离无线通信重新恢复之后，发送端设备查询记录的传输信息，以及继续传输待传输数据中未完成传输的数据块，进而，实现了发送端设备与接收端设备之间的断点续传。
