综上所述，本公开实施例提供的数据传输方法，终端能够接收基站发送的目标传输方向指示信息，之后，基于该目标传输方向指示信息确定在目标模式下进行上行数据传输和下行数据传输的传输方向，该目标模式为终端基于不同载波分别进行上行数据传输和下行数据传输的模式，通过该方法，终端能够在目标模式下获取动态的传输方向指示信息，进而完成目标模式下的数据传输。
图4是根据一示例性实施例示出的另一种数据传输方法的流程图，该数据传输方法可以用于图1所示实施环境，该数据传输方法可以包括如下几个步骤：
在步骤401中，基站获取目标传输方向指示信息。
该目标模式为终端基于不同载波分别进行上行数据传输和下行数据传输的模式。示例的，该目标模式可以为FDD模式。FDD模式是在不同载波上进行上行数据传输和下行数据传输，上下行用不同的频率区分。从基站到终端的下行链路信道采用载波c1，从终端到基站的上行链路信道采用与c1对称的另一载波c2，c1和c2之间预留足够的保护频段。
需要说明的是，本公开实施例中的载波可以是一个独立载波，也可以是一个载波上的频域带宽部分(Band Width Part，BWP)，本公开实施例以载波为一个独立载波为例进行说明。
在步骤402中，基站向终端发送目标传输方向指示信息。
在步骤403中，终端基于目标传输方向指示信息确定在目标模式下进行上行数据传输和下行数据传输的传输方向。
在本公开实施例中，基站获取目标传输方向指示信息可以有多种可实现方式，例如，基站可以预先配置指示单元配比信息，然后从该指示单元配比信息中获取目标传输方向指示信息；或者，基站可以预先配置供终端检测物理层信道的检测时刻，将检测时刻确定为目标传输方向指示信息。本公开实施例以以下两种可实现方式为例对该数据传输方法进行说明。
在第一种可实现方式中，当基站预先配置指示单元配比信息时，如图5所示，该数据传输方法可以包括如下几个步骤：
在步骤501中，基站从预先配置的指示单元配比信息中获取目标传输方向指示信息。
目标传输方向指示信息用于供终端确定在目标模式下进行上行数据传输和下行数据传输的传输方向。该目标模式为终端基于不同载波分别进行上行数据传输和下行数据传输的模式。示例的，目标模式可以为FDD模式。
指示单元配比信息包括多个传输方向指示信息，目标传输方向指示信息是多个传输方向指示信息中的任一个，每个传输方向指示信息包括下行载波的指示单元配比信息和上行载波的指示单元配比信息。
对于FDD系统来讲，为了保证系统的可扩展性，下行载波上和上行载波上都可能预留一部分的资源给未来可能引入的技术使用，在本公开实施例中，基站预先配置多个传输方向指示信息，每个传输方向指示信息的下行载波的指示单元配比信息用于下行载波预留一部分资源，上行载波的指示单元配比信息用于上行载波预留一部分资源。
示例的，指示单元可以为时隙、子帧、无线帧或正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。
假设指示单元为时隙，基站预先配置时隙配比信息，该时隙配比信息包括多个传输方向指示信息，每个传输方向指示信息包括下行载波的时隙配比信息和上行载波的时隙配比信息。基站从该指示单元配比信息中获取目标传输方向指示信息。对于同一个传输方向指示信息来说，下行载波的时隙配比信息与上行载波的时隙配比信息可能相同，也可能不同。当下行载波的时隙状态和上行载波的时隙状态均为unknown状态时，下行载波的时隙配比信息与上行载波的时隙配比信息相同。unknown状态用于指示该时隙既不是上行时隙，也不是下行时隙。
示例的，基站配置的时隙配比信息可以如表1所示。参见表1，该时隙配比信息包括4个传输方向指示信息，编号为1的传输方向指示信息包括下行载波的时隙配比信息f1和上行载波的时隙配比信息f2。f1和f2可能相同，也可能不同。

在步骤502中，基站向终端发送目标传输方向指示信息。
可选的，步骤502可以包括：基站通过物理层信道向终端发送目标传输方向指示信息，该物理层信道为用于承载公共控制信息的物理层信道。示例的，该物理层信道可以为组公用物理下行控制信道(Common Group Physical Downlink Control Channel，GC-PDCCH)。相应地，终端通过物理层信道接收基站发送的目标传输方向指示信息。
以表1所示的指示单元配比信息为例，基站从表1中获取编号为1的传输 方向指示信息，将该传输方向指示信息确定为目标传输方向指示信息，该目标传输方向指示信息包括下行载波的时隙配比信息f1和上行载波的时隙配比信息f2，之后，基站向终端发送该目标传输方向指示信息。
在步骤503中，终端基于目标传输方向指示信息中下行载波的指示单元配比信息确定在目标模式下进行下行数据传输的传输方向，并基于目标传输方向指示信息中上行载波的指示单元配比信息确定在目标模式下进行上行数据传输的传输方向。
示例的，基站将表1中编号为1的传输方向指示信息确定为目标传输方向指示信息，那么终端基于该目标传输方向指示信息中下行载波的时隙配比信息f1确定在目标模式下进行下行数据传输的传输方向，并基于该目标传输方向指示信息中上行载波的时隙配比信息f2确定在目标模式下进行上行数据传输的传输方向。
综上所述，本公开实施例提供的数据传输方法，基站能够从预先配置的指示单元配比信息中获取目标传输方向指示信息，然后向终端发送该目标传输方向指示信息，之后，终端基于该目标传输方向指示信息确定在目标模式下进行上行数据传输和下行数据传输的传输方向，其中，目标模式为终端基于不同载波分别进行上行数据传输和下行数据传输的模式，通过该方法，终端能够在目标模式下获取动态的传输方向指示信息，进而完成目标模式下的数据传输。
在第二种实现方式中，当基站预先配置供终端检测物理层信道的检测时刻时，第一方面，检测时刻可以用于指示终端检测承载有下行载波的指示单元配比信息的物理层信道，或者检测承载有上行载波的指示单元配比信息的物理层信道；第二方面，检测时刻可以仅指示终端检测承载有指示单元配比信息的物理层信道，然后由终端基于预设规则确定检测时刻是用于检测承载有下行载波的指示单元配比信息的物理层信道，还是用于检测承载有下行载波的指示单元配比信息的物理层信道。下面以这两个方面为例对该数据传输方法进行说明。
第一方面，如图6所示，该数据传输方法可以包括如下几个步骤：
在步骤601中，基站配置第一检测时刻和第二检测时刻。
第一检测时刻为终端用于检测第一物理层信道的时刻，第二检测时刻为终端用于检测第二物理层信道的时刻。其中，第一物理层信道承载有下行载波的指示单元配比信息，第二物理层信道承载有上行载波的指示单元配比信息。下 行载波的指示单元配比信息用于下行载波预留一部分资源，上行载波的指示单元配比信息用于上行载波预留一部分资源。第一物理层信道和第二物理层信道为用于承载公共控制信息的物理层信道。示例的，该物理层信道可以为GC-PDCCH。
需要说明的是，第一物理层信道和第二物理层信道所在的位置(也称作搜索空间(search space))可以相同，也可以不同。
在本公开实施例中，第一检测时刻的检测周期和第二检测时刻的检测周期可以相同，也可以不同。
示例的，指示单元可以为时隙、子帧、无线帧或OFDM符号。
其中，步骤601可以包括：基站基于高层信令、媒体访问控制单元(Media Access Control control element，MAC CE)或物理层信令在基站配置第一检测时刻和第二检测时刻。
关于高层信令和物理层信令的说明可以参考相关技术，在此不再赘述。
在步骤602中，基站获取预先配置的第一检测时刻和第二检测时刻。
基站获取步骤601配置的第一检测时刻和第二检测时刻。
在步骤603中，基站将第一检测时刻和第二检测时刻确定为目标传输方向指示信息。
基站将步骤602获取的第一检测时刻和第二检测时刻确定为目标传输方向指示信息。目标传输方向指示信息用于供终端确定在目标模式下进行上行数据传输和下行数据传输的传输方向。该目标模式为终端基于不同载波分别进行上行数据传输和下行数据传输的模式。示例的，目标模式可以为FDD模式。
在步骤604中，基站向终端发送目标传输方向指示信息。
在本步骤中，基站可以通过同一信令向终端发送第一检测时刻和第二检测时刻。或者，基站可以通过不同信令向终端分别发送第一检测时刻和第二检测时刻，本公开实施例对此不做限定。
在步骤605中，终端在第一检测时刻检测第一物理层信道，并基于检测的下行载波的指示单元配比信息确定在目标模式下进行下行数据传输的传输方向。
终端在第一检测时刻检测第一物理层信道，由于第一物理层信道承载有下行载波的指示单元配比信息，所以，终端能够得到下行载波的指示单元配比信息，进而能够根据下行载波的指示单元配比信息确定在目标模式下进行下行数 据传输的传输方向。
在步骤606中，终端在第二检测时刻检测第二物理层信道，并基于检测的上行载波的指示单元配比信息确定在目标模式下进行上行数据传输的传输方向。
终端在第二检测时刻检测第二物理层信道，由于第二物理层信道承载有上行载波的指示单元配比信息，所以，终端能够得到上行载波的指示单元配比信息，进而能够根据上行载波的指示单元配比信息确定在目标模式下进行上行数据传输的传输方向。
假设指示单元为时隙，图7示例性示出了第一检测时刻t1和第二检测时刻t2的示意图，图7中，横轴为时域，纵轴为频域，终端在t1检测第一物理层信道得到下行载波的时隙配比信息，在t2检测第二物理层信道得到上行载波的时隙配比信息，终端基于下行载波的时隙配比信息确定在目标模式下进行下行数据传输的传输方向，并基于上行载波的时隙配比信息确定在目标模式下进行上行数据传输的传输方向。
综上所述，本公开实施例提供的数据传输方法，基站预先配置供终端检测物理层信号的检测时刻，基站通过检测时刻指示终端检测承载有下行载波的指示单元配比信息的物理层信道，或者检测承载有上行载波的指示单元配比信息的物理层信道，使得终端确定在目标模式下进行上行数据传输和下行数据传输的传输方向，其中，目标模式为终端基于不同载波分别进行上行数据传输和下行数据传输的模式，通过该方法，终端能够在目标模式下获取动态的传输方向指示信息，进而完成目标模式下的数据传输。
第二方面，如图8所示，该数据传输方法可以包括如下几个步骤：
在步骤701中，基站获取预先配置的多个第三检测时刻，每个第三检测时刻为终端用于检测一个物理层信道的时刻。
物理层信道承载有指示单元配比信息，物理层信道为用于承载公共控制信息的物理层信道。示例的，该物理层信道可以为GC-PDCCH。
在本公开实施例中，第三检测时刻仅指示终端检测承载有指示单元配比信息的物理层信道。示例的，指示单元可以为时隙、子帧、无线帧或OFDM符号。
在步骤702中，基站将多个第三检测时刻确定为目标传输方向指示信息。
基站将步骤701获取的多个第三检测时刻确定为目标传输方向指示信息。
在步骤703中，基站向终端发送目标传输方向指示信息。
在步骤704中，基站通过RRC信令、MAC CE或物理层信令向终端发送预设规则。相应地，终端接收基站通过RRC信令、MAC CE或物理层信令发送的预设规则。
该预设规则用于指示多个第三检测时刻中用于检测第一物理层信道的第一检测时刻和用于检测第二物理层信道的第二检测时刻。其中，第一物理层信道承载有下行载波的指示单元配比信息，第二物理层信道承载有上行载波的指示单元配比信息。
假设第三检测时刻有4个，示例的，预设规则可以为：第1个第三检测时刻为用于检测第一物理层信道的第一检测时刻，第2个第三检测时刻为用于检测第二物理层信道的第二检测时刻，第3个检测时刻为用于检测第一物理层信道的第一检测时刻，第4个检测时刻为用于检测第二物理层信道的第二检测时刻，第一检测时刻和第二检测时刻相交错。或者，预设规则可以为：前2个第三检测时刻为用于检测第一物理层信道的第一检测时刻，后2个第三检测时刻为用于检测第二物理层信道的第二检测时刻，连续的2个第三检测时刻为一组。在本公开实施例中，预设规则的内容可以有多种，本公开实施例对预设规则的内容不做限定。
需要说明的是，步骤704和步骤703无先后顺序，即可以先执行步骤703后执行步骤704，也可以先执行步骤704后执行步骤703，也可以同时执行步骤703和步骤704。
还需要补充说明的是，在本公开实施例中，步骤704为可选步骤，即基站可以不向终端发送预设规则，在这种情况下，预设规则可以是协议中预先设定的。
在步骤705中，终端基于预设规则确定多个第三检测时刻中用于检测第一物理层信道的第一检测时刻和用于检测第二物理层信道的第二检测时刻。
第一物理层信道承载有下行载波的指示单元配比信息，第二物理层信道承载有上行载波的指示单元配比信息。下行载波的指示单元配比信息用于下行载波预留一部分资源，上行载波的指示单元配比信息用于上行载波预留一部分资源。
一方面，终端可以基于步骤704中基站发送的预设规则确定第一检测时刻 和第二检测时刻，另一方面，终端可以基于协议中预先设定的预设规则确定第一检测时刻和第二检测时刻。
在步骤706中，终端在第一检测时刻检测第一物理层信道，并基于检测的下行载波的指示单元配比信息确定在目标模式下进行下行数据传输的传输方向。
终端在第一检测时刻检测第一物理层信道，由于第一物理层信道承载有下行载波的指示单元配比信息，所以，终端能够得到下行载波的指示单元配比信息，进而能够根据下行载波的指示单元配比信息确定在目标模式下进行下行数据传输的传输方向。
在步骤707中，终端在第二检测时刻检测第二物理层信道，并基于检测的上行载波的指示单元配比信息确定在目标模式下进行上行数据传输的传输方向。
终端在第二检测时刻检测第二物理层信道，由于第二物理层信道承载有上行载波的指示单元配比信息，所以，终端能够得到上行载波的指示单元配比信息，进而能够根据上行载波的指示单元配比信息确定在目标模式下进行上行数据传输的传输方向。
假设指示单元为时隙，图9示例性示出了终端基于预设规则确定第二检测时刻的示意图，参见图9，基站通过下行载波向终端发送4个第三检测时刻，终端基于预设规则确定第1个第三检测时刻和第3个第三检测时刻为第二检测时刻，用于检测承载有上行载波的指示单元配比信息的第二物理层信道。
综上所述，本公开实施例提供的数据传输方法，基站预先配置供终端检测物理层信号的检测时刻，基站通过检测时刻指示终端检测承载有指示单元配比信息的物理层信道，然后由终端基于预设规则确定检测时刻是用于指示终端检测承载有下行载波的指示单元配比信息的物理层信道，还是用于指示终端检测承载有下行载波的指示单元配比信息的物理层信道，进而使得终端确定在目标模式下进行上行数据传输和下行数据传输的传输方向，其中，目标模式为终端基于不同载波分别进行上行数据传输和下行数据传输的模式，通过该方法，终端能够在目标模式下获取动态的传输方向指示信息，进而完成目标模式下的数据传输。
需要说明的是，本公开实施例提供的数据传输方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行相应增减，任何熟悉本技术领域的 技术人员在本公开揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本公开的保护范围之内，因此不再赘述。
