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公开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、本公开的一些方面相一致的装置和方法的例子。
诸如AR(Augmented Reality，增强现实)/VR(Virtual Reality，虚拟现实)、车车通信等新型互联网应用的不断涌现对无线通信技术提出了更高的要求，驱使无线通信技术不断进行演进以满足应用的需求。目前，蜂窝移动通信技术正在处于新一代技术的演进阶段。这里所说的新一代技术的一个重要特点就是支持多种业务类型的灵活配置。由于不同的业务类型对于无线通信技术有不同的要求，如eMBB(enhanced Mobile Broad Band，增强移动宽带)业务类型主要的要求侧重在大带宽，高速率等方面；URLLC(Ultra Reliable Low Latency  Communication，超高可靠超低时延通信)业务类型主要的要求侧重在较高的可靠性以及低的时延方面；mMTC(massive Machine Type Communication，大型机器类通信)业务类型主要的要求侧重在大的连接数方面。因此，新一代的无线通信系统需要灵活和可配置的设计来支持多种业务类型的传输。
对于LTE系统中的动态调度来说，一个调度指令只能指示一个时频资源，该时频资源用于指示时域单元中的频域资源。这里所说的时域单元是时间上的单位，可以是符号、子帧、时隙、无线帧等通信系统中常用的时域单元。请参考图1，其示出了LTE系统中的资源调度方法的示意图。图1中以时域单元为子帧，且一个阴影区域和一个白色填充区域组成一个子帧为例进行说明，其中，阴影区域是下行控制区域，用于传输控制指令，这里的控制指令包括调度指令，以指示UE在其箭头所指示的一个时频资源上进行数据传输；白色填充区域是下行数据区域，即调度指令的箭头所指示的时频资源，用于供UE进行数据传输。
由于一个调度指令只能指示一个时频资源，那么，在UE每次进行数据传输时都要传输调度指令，导致信令开销较大。本实施例中，由于一个数据传输配置信息可以指示至少两个时频资源，且该至少两个时频资源信息可以用于承载独立的数据块，即，该至少两个时频资源可以用来传输独立的数据包，所以，不必在UE每次进行数据传输时都要传输数据传输配置信息，从而减少了信令开销。
非授权频谱是竞争使用的频谱。多个不同制式的通信系统可以竞争使用非授权频谱上的频域资源。比如，WiFi(Wireless Fidelity，无线保真)系统和LTE系统可以竞争使用非授权频谱上的频域资源。若LTE系统中为UE分配的时频资源是非授权频谱上的时频资源，由于该信道可能被其他制式的通信系统占用，即信道占用具有不确定性，所以，即使通过调度指令为UE分配了一个时频资源，UE可能并不能成功占用该时频资源，导致UE无法在该时频资源上进行数据传输。请参考图2，其示出了非授权频谱的资源分配的示意图，其中，阴影区域是调度指令，白色填充区域是时频资源，调度指令的箭头指向的是分配给UE的一个时频资源，UE占用该时频资源之前需要进行LBT(Listen Before Talk，载波监听)，即黑色填充区域。当监听到该信道被占用，即LBT失败时，UE无法占用该时频资源。
本实施例中，由于一次传输的数据传输配置信息可以指示至少两个时频资源，对于该至少两个时频资源，若UE未成功占用到第一个时频资源，则可以继续占用下一个时频资源，依此类推，这样可以提高UE成功占用时频资源的概率，也就提高了数据传输的成功率。
下面将对本公开实施例提供的数据传输方法所涉及到的实施环境进行简要的说明。
图3为本公开实施例提供的数据传输方法所涉及到的实施环境的示意图，如图1所示，该实施环境可以包括UE 301和至少一个基站302(图3中仅示出了一个基站302)，其中，基站302可以为UE分配至少两个时频资源，并将该至少两个时频资源通知给UE301，UE301根据该至少两个时频资源进行数据传输。
图4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，该数据传输方法应用于图3所示的实施环境中，如图4所示，该数据传输方法包括以下步骤。
在步骤401中，基站为UE分配至少两个时频资源，该时频资源用于指示时域单元中的频域资源。
在步骤402中，基站将至少两个时频资源通知给UE。
在步骤403中，UE获取数据传输配置信息。
在步骤404中，UE根据数据传输配置信息确定至少两个时频资源。
在步骤405中，对于被UE占用的各个时频资源，UE在时频资源所指示的时域单元中的频域资源位置进行数据传输。
其中，步骤401-402可以单独实现成为基站侧的实施例，步骤403-405可以单独实现成为UE侧的实施例。
综上所述，本公开提供的数据传输方法，UE可以根据数据传输配置信息确定至少两个时频资源，在其占用某个时频资源时，即可在该时频资源所指示的时域单元中的频域资源位置进行数据传输。由于在非授权频谱上，信道占用具有不确定性，所以，通过数据传输配置信息指示至少两个时频资源时，可以提高UE占用到时频资源的概率，解决了一个调度指令只能指示一个时频资源时，若UE占用不到该时频资源，则无法进行数据传输的问题，从而达到了提 高数据传输的成功率的效果。另外，由于一个数据传输配置信息可以指示至少两个时频资源，解决了一个调度指令只能指示一个时频资源时，在UE每次进行数据传输时都要传输调度指令，导致信令开销较大的问题，从而节省了信令开销。
本公开中，UE获取数据传输配置信息的实现方式有三种，下面分别以三个实施例对这三种实现方式进行详细说明。
图5是根据另一示例性实施例示出的一种数据传输方法的流程图，该数据传输方法应用于图3所示的实施环境中，如图5所示，该数据传输方法包括如下步骤。
在步骤501中，基站为UE分配至少两个时频资源，该时频资源用于指示时域单元中的频域资源。
一个时频资源包括一个时域单元和一个频域资源，其中，时域单元是时间上的单位，可以是符号、子帧、时隙、无线帧等通信系统中常用的时域单元。
本实施例中，可以预先对时域进行划分，为得到的每个时域单元设置一个时域单元标识，本实施例不限定时域的划分方式。同理，可以预先对频域进行划分，为得到的每个频域资源设置一个频域资源标识，本实施例不限定频域的划分方式。此时，一个时域单元标识和一个频域资源标识可以唯一地标识一个时频资源。
其中，基站可以通过任何方式为UE分配至少两个时频资源，本实施例不作限定。
在步骤502中，基站在数据传输配置信息集合中获取与至少两个时频资源对应的第一指示信息，该数据传输配置信息集合是通信协议中指定的。
基站中预先配置有通信协议中指定的数据传输配置信息集合，该数据传输配置信息集合中包括至少一条数据传输配置信息，且每条数据传输配置信息至少包括索引参数、时域单元标识参数和频域资源标识参数。
索引参数是用于标识数据传输配置信息的参数，索引参数的位数可以由数据传输配置信息集合中所包括的数据传输配置信息的条数确定，且需保证索引参数所表示的数值大于等于数据传输配置信息的条数。比如，数据传输配置信息集合中包括3条数据传输配置信息，则索引参数的位数可以是2比特，如分别用00、01和10表示这三条数据传输配置信息。又比如，数据传输配置信息 集合中包括8条数据传输配置信息，则索引参数的位数可以是3比特。
时域单元标识参数包括至少一个时域单元标识。比如，时域单元标识参数中时域单元标识分别是0、2、4，或，时域单元标识参数中时域单元标识分别是1、3、4等等，本实施例不作限定。
频域资源标识参数包括至少一个频域资源标识。比如，频域资源标识参数中频域资源标识分别是1、2、3，或，频域资源标识参数中频域资源标识是1。
需要说明的是，若时域单元标识参数中时域单元标识的数量和频域资源标识参数中频域资源标识的数量同时为1，则该数据传输配置信息中只指示了一个时频资源，为了避免这种情况，可以规定时域单元标识参数中时域单元标识的数量和频域资源标识参数中频域资源标识的数量不能同时为1。
可选的，数据传输配置信息除了包括索引参数、时域单元标识参数和频域资源标识参数之外，还可以包括其他参数。比如，数据传输配置信息还包括MCS(Modulation and Coding Scheme，调制与编码策略)标识参数，该MCS标识参数用于指示在该时频资源进行数据传输时的调制与编码策略，其包括至少一个MCS标识，比如，MCS标识参数中MCS标识分别是等级1、2、3。
需要说明的是，数据传输配置信息中任一参数的数值可以是一个绝对值，也可以是相对于某个参考值的偏移值。以时域单元标识参数为例，假设时域单元标识参数中的时域单元标识分别是1、3、4；若该数值是绝对值，则其指示的分别是时域单元1、时域单元3和时域单元4；若该数值是相对于时域单元1的偏移值，则其指示的分别是时域单元2、时域单元4和时域单元5。
请参考下表一，其以数据传输配置信息包括索引参数、时域单元标识参数、频域资源标识参数和MCS标识参数为例进行说明，在其他实现方式中，该表格可以包含更多或更少的配置信息。

基站在确定为UE分配的至少两个时频资源后，可以在数据传输配置信息集合中查找用于指示该时频资源的数据传输配置信息，并获取该数据传输配置 信息中的索引参数的数值，将该数值确定为第一指示信息。
可选的，基站可以通过步骤503或步骤504向UE通知该至少两个时频资源。
在步骤503中，基站将第一指示信息发送给UE，并将数据传输配置信息集合发送给UE，执行步骤505。
在本步骤中，基站除了向UE发送第一指示信息之外，还向UE发送数据传输配置信息集合。其中，基站可以先发送数据传输配置信息集合，再发送第一指示信息。
需要说明的是，在基站第一次执行本实施例提供的方法时，可以向UE发送数据传输配置信息集合，UE对该数据传输配置信息集合进行存储；后续，基站再次执行本实施例提供的方法时，可以不再发送数据传输配置信息集合，以节省传输资源。
基站可以将第一指示信息携带在已有的指令或新的指令中，将该指令发送给UE。其中，当该指令是第一调度指令时，将第一指示信息发送给UE，包括：将第一指示信息添加到第一调度指令中；将第一调度指令发送给UE。
下面对基站将第一指示信息添加到指令中的添加方式进行介绍。本实施例中以指令为第一调度指令为例，若将第一指示信息添加到其他指令中，其添加方式与下面所述的两种添加方式相同，此处不作赘述。
在第一种添加方式中，当第一指示信息在第一调度指令中的位置固定时，将第一指示信息添加到第一调度指令中固定的位置处。
第一指示信息在第一调度指令中的位置固定包括两种情况：第一种情况是第一指示信息的位数固定，此时，第一指示信息在第一调度指令中的起始位置和结束位置均固定；第二种情况是第一指示信息的位数不固定，此时，可以是第一指示信息在第一调度指令中的起始位置固定，结束位置不固定，也可以是第一指示信息在第一调度指令中的结束位置固定，起始位置不固定，本实施例不作限定。
若第一指示信息的位数固定，且其在第一调度指令中的位置固定，则可以在通信协议中指定位置信息；也可以在基站第一次向UE发送第一调度指令之前指示位置信息，UE对该位置信息进行存储，后续，基站不需要每次向UE发送第一调度指令之前指示该位置信息；也可以在基站每次向UE发送第一调度指令之前指示该位置信息。其中，位置信息可以包括起始位置和结束位置， 或，可以包括起始位置和位数，或，可以包括结束位置和位数。
若第一指示信息的位数不固定，且其在第一调度指令中的位置固定，则可以在通信协议中指定该起始位置或结束位置，基站还需要在每次发送的第一调度指令之前指示第一指示信息的位数；或者，也可以在基站第一次向UE发送第一调度指令之前指示该起始位置或结束位置，基站还需要在每次发送的第一调度指令中指示第一指示信息的位数；或者，基站可以在每次发送的第一调度指令之前指示第一指示信息的起始位置和结束位置。
以第一指示信息的位数固定，且其在第一调度指令中的位置固定为例，假设第一指示信息在第一调度指令中的起始位置是第5比特，位数是2，则基站可以将该第一指示信息的数值添加到第一调度指令中第5-6比特的位置处。
在第二种添加方式中，当第一指示信息在第一调度指令中的位置不固定时，生成位置信息，位置信息用于指示本次第一指示信息在第一调度指令中的位置，将第一指示信息添加到第一调度指令中位置信息所指示的位置处。
第一指示信息在第一调度指令中的位置不固定包括两种情况：第一种情况是第一指示信息的位数固定，此时，可以根据第一指示信息在第一调度指令中的起始位置推断出结束位置，或者，可以根据第一指示信息在第一调度指令中的结束位置推断出起始位置。第二种情况是第一指示信息的位数不固定，此时，第一指示信息在第一调度指令中的起始位置和结束位置均不固定。
若第一指示信息的位数固定，且其在第一调度指令中的位置不固定，则可以在通信协议中指定该位数，也可以在基站第一次向UE发送第一调度指令之前指示该位数。此后，基站需要在每次发送的第一调度指令中指示该起始位置和/或结束位置。
若第一指示信息的位数不固定，且其在第一调度指令中的位置不固定，则基站需要在每次发送第一调度指令之前指示该起始位置和结束位置，或者，基站需要在每次发送第一调度指令之前指示该起始位置和位数，或者，基站需要在每次发送第一调度指令之前指示该结束位置和位数。
以第一指示信息的位数不固定，且其在第一调度指令中的位置不固定为例，假设第一指示信息为2比特，且基站将要将其添加到第一调度指令中的第5-6比特的位置处，则基站可以生成用于指示本次第一指示信息位于第一调度指令中第5-6比特的位置信息，再将第一指示信息添加到第一调度指令中的第5-6比特的位置处。
在步骤504中，基站将第一指示信息发送给UE，执行步骤505。
其中，基站将第一指示信息发送给UE的流程与步骤503中基站将第一指示信息发送给UE的流程相同，此处不作赘述。
在本步骤中，UE中预先配置有通信协议中指定的数据传输配置信息集合。
在步骤505中，UE获取基站发送的第一指示信息；在数据传输配置信息集合中获取与第一指示信息对应的数据传输配置信息获取数据传输配置信息。
当基站执行步骤503时，数据传输配置信息集合是基站发送的；当基站执行步骤504时，数据传输配置信息集合是通信协议中指定的，且UE中配置的数据传输配置信息集合与基站中配置的数据传输配置信息集合相同。
其中，UE获取第一指示信息的方式与基站发送第一指示信息的方式相同。即，当基站将第一指示信息携带在已有的指令中时，UE从该已有的指令中获取第一指示信息；当基站将该第一指示信息携带在新的指令中时，UE从该新的指令中获取第一指示信息。当指令是第一调度指令时，获取基站发送的第一指示信息，包括：接收基站发送的第一调度指令；从第一调度指令中获取第一指示信息。
对应于基站将第一指示信息添加到指令中的两种添加方式，UE从第一调度指令中获取第一指示信息也有两种获取方式，下面分别对这两种获取方式进行介绍。本实施例中以指令为第一调度指令为例，若将第一指示信息添加到其他指令中，其获取方式与下面所述的两种获取方式相同，此处不作赘述。
在第一种获取方式中，当第一指示信息在第一调度指令中的位置固定时，从第一调度指令中固定的位置处读取第一指示信息。
若第一指示信息的位数固定，且其在第一调度指令中的位置固定，则UE可以从通信协议中获取第一指示信息在第一调度指令中的位置信息；也可以在基站第一次发送第一调度指令之前获取该位置信息，UE对该位置信息进行存储，后续，基站不需要每次向UE发送第一调度指令之前指示该位置信息；还可以在基站每次发送第一调度指令之前获取该位置信息。其中，位置信息可以包括起始位置和结束位置，或，可以包括起始位置和位数，或，可以包括结束位置和位数。UE再根据上述位置信息确定第一指示信息在第一调度指令中的位置，从该位置处读取第一指示信息。
若第一指示信息的位数不固定，且其在第一调度指令中的位置固定，则UE可以从通信协议中获取第一指示信息在第一调度指令中的起始信息，或， 可以在基站第一次发送第一调度指令之前获取第一指示信息的起始位置，再从本次接收到的第一调度指令中获取第一指示信息的位数；或者，UE可以从通信协议中获取第一指示信息在第一调度指令中的结束信息，或，可以在基站第一次发送第一调度指令之前获取第一指示信息的结束位置，再从本次接收到的第一调度指令中获取第一指示信息的位数；或者，UE可以在基站每次发送第一调度指令之前获取第一指示信息的起始位置和结束位置。UE再根据上述信息确定第一指示信息在第一调度指令中的位置，从该位置处读取第一指示信息。
以第一指示信息的位数固定，且其在第一调度指令中的位置固定为例，假设第一指示信息在第一调度指令中的起始位置是第5比特，位数是2，则UE可以从第一调度指令中第5-6比特的位置处读取第一指示信息。
在第二种获取方式中，当第一指示信息在第一调度指令中的位置不固定时，获取位置信息，位置信息用于指示本次第一指示信息在第一调度指令中的位置；从第一调度指令中位置信息所指示的位置处读取第一指示信息。
若第一指示信息的位数固定，且其在第一调度指令中的位置不固定，则UE可以从通信协议中获取第一指示信息的位数，或，在基站第一次发送第一调度指令之前获取第一指示信息的位数，再从本次接收到的第一调度指令中获取第一指示信息的起始位置和/或结束位置，根据上述信息确定第一指示信息在第一调度指令中的位置，从该位置处读取第一指示信息。
若第一指示信息的位数不固定，且其在第一调度指令中的位置不固定，则UE可以在基站每次发送第一调度指令之前获取第一指示信息的起始位置和结束位置；或者，UE可以在基站每次发送第一调度指令之前获取第一指示信息的起始位置和位数；或者，UE可以在基站每次发送第一调度指令之前获取第一指示信息的结束位置和位数。UE再根据上述信息确定第一指示信息在第一调度指令中的位置，从该位置处读取第一指示信息。
以第一指示信息的位数不固定，且其在第一调度指令中的位置不固定为例，假设第一指示信息为2比特，且位置信息指示第一指示信息添加到第一调度指令中的第5-6比特的位置处，则UE根据该位置信息从第一调度指令中第5-6比特处读取第一指示信息。
UE在得到第一指示信息后，从数据传输配置信息集合中查找索引参数为该第一指示信息的数据传输配置信息。
在步骤506中，UE根据数据传输配置信息确定至少两个时频资源。
UE从数据传输配置信息中获取时域单元标识和频域资源标识，再根据时域单元标识和时域资源标识确定至少两个时频资源。
在步骤507中，对于被UE占用的各个时频资源，UE在时频资源所指示的时域单元中的频域资源位置进行数据传输。
对于每个时频资源，UE可以在占用该时频资源之前进行LBT，即监听该信道是否被占用，若该信道被占用，则UE放弃在该时频资源上传输数据，等待下一个时频资源；若该信道未被占用，则UE占用该信道，在该时频资源上进行数据传输。
其中，步骤501-504可以单独实现成为基站侧的实施例，步骤505-507可以单独实现成为UE侧的实施例。
综上所述，本公开提供的数据传输方法，UE可以根据数据传输配置信息确定至少两个时频资源，在其占用某个时频资源时，即可在该时频资源所指示的时域单元中的频域资源位置进行数据传输。由于在非授权频谱上，信道占用具有不确定性，所以，通过数据传输配置信息指示至少两个时频资源时，可以提高UE占用到时频资源的概率，解决了一个调度指令只能指示一个时频资源时，若UE占用不到该时频资源，则无法进行数据传输的问题，从而达到了提高数据传输的成功率的效果。另外，由于一个数据传输配置信息可以指示至少两个时频资源，解决了一个调度指令只能指示一个时频资源时，在UE每次进行数据传输时都要传输调度指令，导致信令开销较大的问题，从而节省了信令开销。
通过传输第一指示信息，而不是传输时域单元标识和频域资源标识，可以通过减少所传输的数据来节省传输资源。
图6是根据另一示例性实施例示出的一种数据传输方法的流程图，该数据传输方法应用于图3所示的实施环境中，如图6所示，该数据传输方法包括如下步骤。
在步骤601中，基站为UE分配至少两个时频资源，该时频资源用于指示时域单元中的频域资源。
其中，步骤601的实现流程详见步骤501中的描述。
在步骤602中，基站根据至少两个时频资源生成数据传输配置信息；将数 据传输配置信息携带在第二调度指令中发送给UE。
与步骤502中的数据传输配置信息相比，本步骤中生成的数据传输配置信息不包含索引参数，其所包括的时域单元标识参数、频域资源标识参数以及其他参数的内容详见步骤502中的描述。
其中，基站可以将数据传输配置信息携带在已有的指令或新的指令中，将该指令发送给UE。本实施例中，以指令是第二调度指令为例进行说明。
在步骤603中，UE接收基站发送的第二调度指令；从第二调度指令中获取数据传输配置信息。
UE获取数据传输配置信息的方式与基站发送数据传输配置信息的方式相同。即，当基站将数据传输配置信息携带在已有的指令中时，UE从该已有的指令中获取数据传输配置信息；当基站将该数据传输配置信息携带在新的指令中时，UE从该新的指令中获取数据传输配置信息。本实施例中，以指令是第二调度指令为例进行说明。
在步骤604中，UE根据数据传输配置信息确定至少两个时频资源。
在步骤605中，对于被UE占用的各个时频资源，UE在时频资源所指示的时域单元中的频域资源位置进行数据传输。
其中，步骤604-605的实现流程详见步骤506-507中的描述，此处不作赘述。
其中，步骤601-602可以单独实现成为基站侧的实施例，步骤603-605可以单独实现成为UE侧的实施例。
综上所述，本公开提供的数据传输方法，UE可以根据数据传输配置信息确定至少两个时频资源，在其占用某个时频资源时，即可在该时频资源所指示的时域单元中的频域资源位置进行数据传输。由于在非授权频谱上，信道占用具有不确定性，所以，通过数据传输配置信息指示至少两个时频资源时，可以提高UE占用到时频资源的概率，解决了一个调度指令只能指示一个时频资源时，若UE占用不到该时频资源，则无法进行数据传输的问题，从而达到了提高数据传输的成功率的效果。另外，由于一个数据传输配置信息可以指示至少两个时频资源，解决了一个调度指令只能指示一个时频资源时，在UE每次进行数据传输时都要传输调度指令，导致信令开销较大的问题，从而节省了信令开销。
图7是根据另一示例性实施例示出的一种数据传输方法的流程图，该数据传输方法应用于图3所示的实施环境中，如图7所示，该数据传输方法包括如下步骤。
在步骤701中，基站为UE分配至少两个时频资源，该时频资源用于指示时域单元中的频域资源。
其中，步骤701的实现流程详见步骤501中的描述，此处不作赘述。
本实施例中，基站可以通过步骤702或步骤703向UE通知该至少两个时频资源。
在步骤702中，基站获取在分配至少两个时频资源之前生成的时间窗口信息，该时间窗口信息用于指示一个时间窗口内的至少一个时域单元；根据该至少两个时频资源确定频域资源信息，根据频域资源信息生成第三调度指令，该频域资源信息用于指示时域单元中的频域资源；将时间窗口信息和第三调度指令发送给UE，执行步骤704。
一个时间窗口内可以包括至少一个时域单元。基站先指定一个时间窗口；再在该时间窗口中确定至少一个时域单元，该至少一个时域单元即为将要为UE分配的至少两个时频资源中的时域单元；再生成用于指示该至少一个时域单元的时间窗口信息，以通过该时间窗口信息来指示该至少两个时频资源中的时域单元。
频域资源信息可以包括至少一个频域资源标识，详见步骤502中的描述。
需要说明的是，当时间窗口信息指示该时间窗口内的一个时域单元时，频域资源信息包括至少两个频域资源标识；当时间窗口信息指示该时间窗口内的至少两个时域单元时，频域资源信息包括至少一个频域资源标识，以保证时间窗口信息和频域资源信息指示至少两个时频资源。
本实施例提供了生成第三调度指令的两种实现方式，下面分别对这两种实现方式进行介绍。
在第一种实现方式中，根据频域资源信息生成第三调度指令，包括：在频域资源信息集合中获取与频域资源信息对应的第二指示信息，该频域资源信息集合是通信协议中指定的；生成携带有第二指示信息的第三调度指令。
基站中预先配置有通信协议中指定的频域资源信息集合，该频域资源信息集合中包括至少一条频域资源信息，且每条频域资源信息至少包括索引参数和频域资源标识参数。其中，索引参数和频域资源标识参数详见步骤502中的描 述。
可选的，频域资源信息除了包括索引参数和频域资源标识参数之外，还可以包括其他参数。比如，频域资源信息还包括MCS标识参数，详见步骤502中的描述。
基站在确定为UE分配的至少两个时频资源后，可以在频域资源信息集合中查找用于指示该时频资源中的频域资源的频域资源信息，并获取该频域资源信息中的索引参数的数值，将该数值确定为第二指示信息。
基站在得到第二指示信息后，可以将第二指示信息携带在已有的指令或新的指令中，将该指令发送给UE。本实施例中以指令是第三调度指令为例进行说明，此时，将第二指示信息添加到第三调度指令中的流程与将第一指示信息添加到第一调度指令中的流程相同，此处不作赘述。
需要说明的是，频域资源信息集合可以由基站发送给UE，也可以由UE从通信协议中获取，本实施例不作限定。当频域资源信息集合由基站发送给UE时，基站可以每次发送第三调度指令时发送频域资源信息集合，也可以在第一次执行本实施例提供的方法时，向UE发送频域资源信息集合，UE对该频域资源信息集合进行存储；后续，基站再次执行本实施例提供的方法时，可以不再发送频域资源信息集合，以节省传输资源。
在第二种实现方式中，根据频域资源信息生成第三调度指令，包括：生成携带有频域资源信息的第三调度指令。
基站在确定为UE分配的至少两个时频资源后，可以生成用于指示该时频资源中的频域资源的频域资源信息，将该频域资源信息携带在已有的指令或新的指令中，将该指令发送给UE。本实施例中，以指令是第三调度指令为例进行说明。
其中，基站可以先发送时间窗口信息，再发送第三调度指令；也可以先发送第三调度指令，再发送时间窗口信息；还可以同时发送时间窗口信息和数据传输配置集合，本实施例不对时间窗口信息和第三调度指令的发送顺序作限定。
在步骤703中，基站根据该至少两个时频资源确定频域资源信息，根据频域资源信息生成第三调度指令，该频域资源信息用于指示时域单元中的频域资源；将第三调度指令发送给UE，执行步骤704。
与步骤702相比，本步骤中只发送第三调度指令，不发送时间窗口信息。
在步骤704中，UE获取时间窗口信息。
其中，当基站执行步骤702时，时间窗口信息是基站发送的；当基站执行步骤703时，时间窗口信息是通信协议中指定的。
在步骤705中，UE接收基站发送的第三调度指令，根据第三调度指令获取频域资源信息，该频域资源信息用于指示时域单元中的频域资源。
本实施例提供了获取频域资源信息的两种实现方式，下面分别对这两种实现方式进行介绍。
在第一种实现方式中，根据第三调度指令获取频域资源信息，包括：从第三调度指令中获取第二指示信息；在频域资源信息集合中获取与第二指示信息对应的频域资源信息，该频域资源信息集合是基站发送的，或，该频域资源信息集合是通信协议中指定的。
其中，UE获取第二指示信息以及从频域资源信息集合中获取与第二指示信息对应的频域资源信息的流程，与，UE获取第一指示信息以及从数据传输配置信息集合中获取与第一指示信息对应的数据传输配置信息的流程相同，此处不作赘述。
在第二种实现方式中，根据第三调度指令获取频域资源信息，包括：当第三调度指令中携带有频域资源信息时，从第三调度指令中读取频域资源信息。
UE获取频域资源信息的方式与基站发送频域资源信息的方式相同。即，当基站将频域资源信息携带在已有的指令中时，UE从该已有的指令中获取频域资源信息；当基站将该频域资源信息携带在新的指令中时，UE从该新的指令中获取频域资源信息。本实施例中，以指令是第三调度指令为例进行说明。
在步骤706中，UE根据数据传输配置信息确定至少两个时频资源。
在步骤707中，对于被UE占用的各个时频资源，UE在时频资源所指示的时域单元中的频域资源位置进行数据传输。
其中，步骤706-707的实现流程详见步骤506-507中的描述，此处不作赘述。
请参考图8，UE未能成功占用前两个时频资源，不能在前两个时频资源上传输数据。UE成功占用了第三个时频资源，则可以在第三个时频资源上传输数据。
其中，步骤701-703可以单独实现成为基站侧的实施例，步骤704-707可以单独实现成为UE侧的实施例。
综上所述，本公开提供的数据传输方法，UE可以根据数据传输配置信息确定至少两个时频资源，在其占用某个时频资源时，即可在该时频资源所指示的时域单元中的频域资源位置进行数据传输。由于在非授权频谱上，信道占用具有不确定性，所以，通过数据传输配置信息指示至少两个时频资源时，可以提高UE占用到时频资源的概率，解决了一个调度指令只能指示一个时频资源时，若UE占用不到该时频资源，则无法进行数据传输的问题，从而达到了提高数据传输的成功率的效果。另外，由于一个数据传输配置信息可以指示至少两个时频资源，解决了一个调度指令只能指示一个时频资源时，在UE每次进行数据传输时都要传输调度指令，导致信令开销较大的问题，从而节省了信令开销。
