为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术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。

图1b是现有技术中传统全双工技术传输数据的工作模式原理结构示意图；
图2是本发明所述无线通信数据传输的方法具体实施例的步骤流程图；

图5是本发明一种无线通信数据传输的系统原理结构图。
为使本发明的目的、技术方案及优点更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用于解释本发明，并不用于限定本发明。
在现有技术中，基于全双工技术的移动终端与基站之间传输的数据采用全双工的工作模式，即是使用上行频率信道传输从移动终端发射到基站的数据，使用下行频率信道传输从基站发送到移动终端的数据，具体的划分如图1a所示。根据3GPP标准，全双工移动终端的上行频率信道的频率低于下行频率信道的频率，即上行频率信道在频率轴的下端，而下行频率信道在频率轴的上端，下行频率信道和上行频率信道之间有一个频率保护带，以增加上行和下行同时发射和接收的隔离度，减小同时发射和接收的相互干扰。
全双工移动终端的上行发射数据和下行接收数据可同时进行，是全双工的工作模式，即在同一时刻下行频率信道接收数据，同时上行频率信道可发射数据，如图1b所示。由于全双工移动终端在同一时刻可以同时发射和接收的频率信道分配示意图，从图1b中可看出，上行频率信道和下行频率信道可以同时发射和接收数据，但若上行频率信道无数据发射时，则该频率信道是处于空闲状态，这样对上行频率信道造成很大的浪费，而下行频率信道一般需要接收的数据量往往比较大，因此利用全双工技术传输数据时造成频率信道利用率低。
本发明提供了一种无线通信数据传输的方法，如图2所示，所述方法包括：
S1、利用全双工技术，使用下行频率信道接收从基站发送到移动终端的数据。
在本步骤中，采用传统的全双工技术，使用下行频率信道对从基站发出的数据进行接收，并将其传输到移动终端，并且下行频率信道仅用于接收从基站发出的数据。
S2、利用时分复用技术，使用上行频率信道发射移动终端发射到基站的数据，及接收从基站发送到移动终端的数据。
但对于传统的全双工技术中的上行频率信道，则对其采用时分复用的技术进行数据的传输，具体的，则是按照上行频率信道中待发射数据量的大小分配上行频率信道中发射和接收的数据的时间占空比。根据分配出的时间占空比进行数据的发射和接收。
传统的移动台上行频率信道用于移动台发射数据到基站，上述方法为在移动台上行频率信道空闲时利用上行频率信道来接收基站发来的数据，而在移动台要发射数据时则把移动台上行频率信道由接收转为发射，即时分复用移动台的上行频率信道来实现移动台用上行频率信道分时发射和接收数据。
图3为所述方法的具体实施例中上行频率信道的时序图，通过时分复用来实现移动台用上行频率信道分时发射和接收数据。从图3中可看出，在移动台下行频率信道接收数据时，移动台的上行频率信道可分时接收数据和发射数据，上行频率信道被充分利用。
具体的，如图4a-图4c所示，在移动台的上行频率信道上分时复用接收来自基站的发送的数据和发射移动终端传输到基站的数据，其接收和发射数据的时间占空比可根据发射和接收的数据量来确定。在具体实施过程中，需要首先获取移动终端发射到基站的待发射数据量，然后根据所述待发射数据量的大小，分配上行频率信道中发射数据的时间占空比和接收数据的时间占空比，其中，所述上行频率信道中发射数据的时间占空比与待发射数据量成正比例关系，所述上行频率信道中接收数据的时间占空比为上行频率信道传输数据的时间占空比减去发射数据的时间占空比。
在具体的传输过程中，情况一，如图4a所述，当发射数据量大时，则发射的持续时间就会加长，而接收的持续时间则相应的缩短。情况二，如图4b所示，当发射数据量少时，则发射的持续时间就短，而接收的持续时间则相应的加长。情况三，如图4c所示，若在某段时间无发射数据，则这个时间段上行频率信道均可用于接收从基站发送到移动终端的数据。
在上述所述方法的基础上，本发明还提供了一种无线通信数据传输的系统，如图5所示，所述系统包括：第一控制传输模块110和第二控制传输模块120；
所述第一控制传输模块110，用于利用全双工技术，使用下行频率信道接收从基站发送到移动终端的数据。
所述第二控制传输模块120，用于利用时分复用技术，使用上行频率信道发射移动终端发射到基站的数据，及接收从基站发送到移动终端的数据。
