具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
本公开提供的技术方案适用于新一代网络，如5G网络中，为了更好地支持需要高可靠性和低时延的业务，NR系统中支持不基于上行调度(Uplink grant free，简称为UL GF)的数据传输方案，用户设备可以使用半静态分配的周期性的传输时频资源进行UL GF传输，UL GF传输中，NR系统支持在同一个资源周期内对于同一个物理层传输块(Transport Block，简称为TB)的多次重复传输。重复传输次数K通过用户专用的RRC信令进行配置，当重复传输次数为K时，基站会为用户设备配置用于K次重复传输的K个传输时频资源。并且，基站可通过RRC信令为用户设备配置K个传输时频资源中每一个传输时频资源传输数据时所使用的信道编码冗余版本号(Redundancy Version，简称为RV)，对应于不同的RV顺序，用户设备可以确定出能够进行第一次重复传输的传输时频资源。此外，为了更好地支持新空口(New Radio， 简称为NR)技术的前向兼容性，NR系统中可以为一个时域符号的传输方向定义为上行(Uplink，简称为UL)、下行(Downlink，简称为DL)或者未知(unknown/flexible)，NR中支持动态地通过group common PDCCH使用SFI来灵活地控制时域符号的传输方向。
图1A是根据一示例性实施例示出的一种数据传输方法的流程图，图1B是根据一示例性实施例示出的一种数据传输方法的场景图；该数据传输方法可以应用在用户设备上，如图1A所示，该数据传输方法包括以下步骤101-104：
在步骤101中，接收基站通过组通用物理下行控制信道使用时隙模式指示信息指示的时域符号的传输方向。
在一实施例中，通过组通用物理下行控制信承载的SFI信息，时域符号的传输方向可以被动态地指定为上行、或者下行，或者未知。
在步骤102中，基于时域符号的传输方向，确定发生传输方向冲突的传输时频资源，传输时频资源为基站分配的免上行调度的资源周期中的时频资源。
在一实施例中，基站在为用户设备分配用于UL GF传输的传输时频资源时，可通过小区专用RRC信令或者用户设备专用RRC信令半静态地配置传输时频资源中的每一个时域符号的传输方向为上行，由此，在接收到基站通过SFI信息指示的时域符号的传输方向时，可将通过SFI信息指示的时域符号的传输方向为下行或者未知的时域符号所在的传输时频资源确定为发生传输方向冲突的传输时频资源。
在步骤103中，在发生传输方向冲突的传输时频资源的数目小于预设值时，确定资源周期中能够用于传输上行数据的可用时频资源。
在一实施例中，预设值可以为一个小于资源周期中的传输时频资源数目的数值，例如，资源周期中共有8个传输时频资源，预设值可以为4或者6等。
在一实施例中，可以通过以下三种方式中的任一方式获得预设值。
方式一：接收基站通过信令发送的预设值。
在一实施例中，基站可通过下行信令，如RRC信令、或者物理层信令]、或者MAC控制元素(Control Element，简称为CE)向用户设备发送预设值。
在一实施例中，用户设备除了可以基于基站的下行信令获取预设值之外，还可以基于系统协议确定预设值，例如，系统协议预先设定预设值为2。
方式二：基于资源周期中传输时频资源的总数目和第一比例得到。
在一实施例中，可通过计算资源周期中传输时频资源的总数目与第一比例的乘积，得到预设值，例如，资源周期中传输时频资源的总数目为8，第一比例为0.5，则 可得到预设值为4。
方式三：基于资源周期中用户设备所用传输时频资源的数目和第二比例得到。
在一实施例中，可通过计算资源周期中用户设备所用传输时频资源的数目与第二比例的乘积，得到预设值，例如，资源周期中传输时频资源的总数目为8，但是用户设备准备在第三个传输时频资源的位置执行第一次重复传输，则可确定用户设备所用传输时频资源的数目为6个，如果第二比例为0.5，则可得到预设值为3。
在一实施例中，在发生传输方向冲突的传输时频资源的数目小于预设值时，可以理解为资源周期中发生冲突的传输时频资源数目比较小，对数据传输的可靠性影响不是特别大，因此为了降低时延，可继续在资源周期中传输上行数据，因此需要确定出可用时频资源。确定可用时频资源的方法可参见图2A和图3A所示实施例，这里先不详述。
在步骤104中，在可用时频资源上传输上行数据。
在一实施例中，可用时频资源可以理解为资源周期中用户设备能够传输上行数据的时频资源，用户设备可从可用时频资源中选择时频资源进行数据传输，在可用时频资源上传输上行数据的方法可参见图4所示实施例，这里不详述。
在一示例性场景中，如图1B所示，以移动网络为新一代网络，如5G网络并且基站为gNB为例进行示例性说明，在图1B所示的场景中，包括gNB10、UE20，其中，gNB10可通过组通用PDCCH使用SFI信息指示每一个时域符号的传输方向，如果所指示的时域符号的传输方向与UE20的免调度传输的资源周期中的时频资源产生冲突，则UE20可基于冲突的时频资源的数目和位置作出合理的数据传输决策。
本实施例中，通过上述步骤101-104，实现了在GF上行传输和时隙模式指示的时域符号的传输方向发生冲突时，用户设备能够针对GF资源周期中的冲突的时频资源的数目和位置作出合理的数据传输决策，以达到GF资源周期中数据传输的可靠性和时延的均衡。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2A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，图2B是根据一示例性实施例示出的一种数据传输的示意图一，图2C是根据一示例性实施例示出的一种数据传输的示意图一；本实施例利用本公开实施例提供的上述方法，以用户设备如何确定可用时频资源以及如何在可用时频资源上发送数据为例进行示例性说明，如图2A所示，包括如下步骤：
在步骤201中，接收基站通过组通用物理下行控制信道使用时隙模式指示信息 指示的时域符号的传输方向。
在步骤202中，基于时域符号的传输方向，确定发生传输方向冲突的传输时频资源，执行步骤203。
在一实施例中，传输时频资源为基站分配的免上行调度的资源周期中的时频资源。
在一实施例中，步骤201和步骤202的描述可参见图1A所示实施例的步骤101和步骤102的描述，这里不再详述。
在步骤203中，在发生传输方向冲突的传输时频资源的数目小于预设值时，从资源周期中未发生传输方向冲突的传输时频资源中，确定能够进行第一次重复传输的传输时频资源。
在一实施例中，参见图2B，示意了一个包含8个传输时频资源的资源周期，假设RV顺序为『0，3，0，3』，则可以进行第一次重复传输的时频资源的位置为第一个、第三个、第五个、第七个时频资源，若发生传输方向冲突的传输时频资源的资源位置不包括资源周期中的第一个、第三个、第五个、第七个时频资源，假设发生传输方向冲突的传输时频资源为第一个时频资源，则用户设备可从未发生冲突的传输时频资源中，也即在第二至第八个传输时频资源中，确定一个能够进行第一次重复传输的时频资源，例如，RV顺序为『0，3，0，3』时，则可确定第一个能够进行第一次重复传输的传输时频资源为第三个、第五个、第七个时频资源；假设发生传输方向冲突的传输时频资源为第三个时频资源，则用户设备可从未发生冲突的传输时频资源中，也即在第一至第二、第四至第八个传输时频资源中，可确定能够进行第一次重复传输的传输时频资源为第一个、第五个、第七个时频资源。
在一实施例中，参见图2C，假设RV顺序为『0，3，0，3』，可以进行第一次重复传输的时频资源的位置为第一个、第三个、第五个、第七个时频资源，若发生传输方向冲突的传输时频资源的资源位置不包括资源周期中的第一个、第三个、第五个、第七个时频资源，发生传输方向冲突的时频资源为第二个、第四个时频资源，则可将所有未发生传输方向冲突的传输时频资源，也即第一个、第三个、第五个、第六个、第七个、第八个时频资源确定为可用传输时频资源，用户设备可将第一个、第三个、第五个、第七个时频资源确定为进行第一次重复传输的时频资源。
在步骤204中，将能够进行第一次重复传输的传输时频资源以及之后的未发生传输方向冲突的传输时频资源确定为可用时频资源。
在一实施例中，如果发生传输方向冲突的传输时频资源的资源位置包括资源周 期中的第一个时频资源的位置，则第一个时频资源的位置和第一个能够进行第一次重复传输的传输时频资源之间的时频资源为不可用时频资源，例如，图2B中，发生传输方向冲突的传输视频资源为第一个时频资源，而用户可进行第一次重复传输的时频资源为第三个、第五个、第七个时频资源，则虽然第二个时频资源没有发生传输方向冲突，也不可以作为可用传输时频资源，可用传输时频资源只能为第三至第六个时频资源。
在步骤205中，基于在资源周期中对传输块进行重传的次数以及配置的信道编码冗余版本格式，从可用时频资源中确定进行数据重复传输的目标时频资源。
在一实施例中，信道编码冗余版本格式可由基站通过RRC信令配置给用户设备，在UL GF传输中，定义了三种可能的信道编码冗余版本格式：『0，2，3，1』，『0，3，0，3』或者『0，0，0，0』，这里以信道编码冗余版本格式(RV顺序)为『0，3，0，3』描述如何从可用时频资源中确定目标时频资源。参见图2B，假设用于设备确定在资源周期中进行4次重复传输，而RV顺序为『0，3，0，3』，则需要将第五至第八个时域单元确定为目标时频资源。
在步骤206中，在目标时频资源上发送传输块。
本实施例中，公开了一种确定在GF上行传输和时隙模式指示的时域符号的传输方向发生传输方向冲突时，用户设备能够针对GF资源周期中的冲突的时频资源的数目和位置作出合理的数据传输决策，而且基于发生传输方向冲突的时域资源的位置是否包含第一个时域资源，执行了不同的传输决策，最大程度地保证了GF资源周期中数据传输的可靠性和时延的均衡。
图3A是根据一示例性实施例示出的又一种数据传输方法的流程图,图3B是根据一示例性实施例示出的一种数据传输的示意图三；本实施例利用本公开实施例提供的上述方法，以用户设备如何确定可用时频资源以及如何在可用时频资源上发送数据为例进行示例性说明，如图3A所示，包括如下步骤：
在步骤301中，接收基站通过组通用物理下行控制信道使用时隙模式指示信息指示的时域符号的传输方向。
在步骤302中，基于时域符号的传输方向，确定发生传输方向冲突的传输时频资源，传输时频资源为基站分配的免上行调度的资源周期中的时频资源。
在一实施例中，步骤301和步骤302的描述可参见图1A所示实施例的步骤101和步骤102的描述，这里不再详述。
在步骤303中，在发生传输方向冲突的传输时频资源的数目小于预设值时，将 资源周期中所有未发生传输方向冲突的传输时频资源确定为可用时频资源。
在一实施例中，参见图3B，示意了一个包含8个传输时频资源的资源周期，其中发生传输方向冲突的传输时频资源为第一个时频资源，则用户设备可将未发生冲突的传输时频资源，也即第二至第八个时频资源确定为可用时频资源，例如，RV顺序为『0，3，0，3』时，用户设备可在第二个时频资源上传输RV3格式的上行数据；当然，如果发生传输方向冲突的传输时频资源为第三个时频资源，则用户设备可将未发生冲突的传输时频资源第一至第二，以及第四至第八个传输时频资源确定为可用时频资源。
在步骤304中，基于在资源周期中对传输块进行重传的次数以及配置的信道编码冗余版本格式，从可用时频资源中确定进行数据重复传输的目标时频资源。
在一实施例中，由于所有未发生传输方向冲突的时频资源均可作为可用时频资源，则可基于在资源周期中对传输块进行重传的次数以及配置的信道编码冗余版本格式，参见图3B，用户设备想在资源周期中对传输块进行重传的次数为8次，则需要从第一个时频资源开始传输数据，而第一个时频资源为发生传输方向冲突的时频资源，因此可将第二个至第八个时频资源作为目标时频资源，但是在RV顺序为『0，3，0，3』时，第二个时频资源所传输的数据编码格式为第二次重复传输，第一次重复传输发生在第一个时域资源上，由于传输方向发生冲突，因此被取消。
在步骤305中，在目标时频资源上发送传输块。
本实施例中，公开了一种确定在GF上行传输和时隙模式指示的时域符号的传输方向发生传输方向冲突并且冲突的时频资源数目小于预设值时，将所有未发生冲突的时频资源均作为可用时频资源的实现方式，可最大程度地保证GF资源周期中数据传输的可靠性和时延的均衡。
图4是根据一示例性实施例示出的又一种数据传输方法的流程图；本实施例利用本公开实施例提供的上述方法，以用户设备如何基于发生传输方向冲突的时频资源的数目确定是否在资源周期中执行数据传输为例进行示例性说明，如图4所示，包括如下步骤：
在步骤401中，接收基站通过组通用物理下行控制信道使用时隙模式指示信息指示的时域符号的传输方向。
在步骤402中，基于时域符号的传输方向，确定发生传输方向冲突的传输时频资源，传输时频资源为基站分配的免上行调度的资源周期中的时频资源。
在一实施例中，步骤401和步骤402的描述可参见图1A所示实施例的步骤101 和步骤102的描述，这里不再详述。
在步骤403中，确定发生传输方向冲突的传输时频资源的数目是否小于预设值，若小于预设值，则执行步骤404，若大于或者等于预设值，则执行步骤406。
在一实施例中，预设值可以为一个小于资源周期中的传输时频资源数目的数值，例如，资源周期中共有8个传输时频资源，预设值可以为4或者6等。预设值的确定方式可参见图1A所示实施例的步骤103的描述，这里不再详述。
在步骤404中，确定资源周期中能够用于传输上行数据的可用时频资源。
在一实施例中，步骤404的描述可参见图1A所示实施例的步骤104的描述，这里不再详述。
在步骤405中，在可用时频资源上传输上行数据。
在步骤406中，拒绝在资源周期中的任一传输时频资源上传输上行数据。
在一实施例中，在发生传输方向冲突的传输时频资源的数目大于或者等于预设值时，可以理解为资源周期中发生冲突的传输时频资源数目比较大，对数据传输的可靠性影响特别大，因此为了增加数据传输的可靠性，需要取消在资源周期中传输上行数据。
本实施例中，公开了一种基于发生传输方向冲突的时频资源的数目确定是否在资源周期中执行数据传输的实现方式，在发生传输方向冲突的传输时频资源的数目大于或者等于预设值时，可以理解为资源周期中发生冲突的传输时频资源数目比较大，对数据传输的可靠性影响特别大，因此为了增加数据传输的可靠性，需要取消在资源周期中传输上行数据；而在发生传输方向冲突的传输时频资源的数目小于预设值时，可以理解为资源周期中发生冲突的传输时频资源数目比较小，对数据传输的可靠性影响不是特别大，因此为了降低时延，可继续在资源周期中传输上行数据，达到了GF资源周期中数据传输的可靠性和时延的均衡
