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。
在对本公开实施例进行详细的解释说明之前，先对本公开实施例涉及的名词、应用场景和***架构进行简单介绍。
首先，对本公开实施例涉及的名词进行简单解释。
参数指示信息：本公开实施例定义的一种指示信息，由基站发送给终端的调度信令中携带，可以为配置参数或者用于指示配置参数的加扰序列，均为了确定带宽部分上的配置参数。其中，该配置参数即为numerology。
带宽部分：一个载波上的一段频域资源，一个载波包含多段不同的频域资源，即多个不同的带宽部分。
其次，对本公开实施例涉及的应用场景进行简单介绍。
目前，随着诸如AR(Augmented Reality，增强现实)/VR(Virtual Reality，虚拟现实)之类的新型互联网应用的不断涌现，驱使无线通信技术得到快速的发展和演进以满足应用需求。在实际应用场景中，不同业务类型对无线通信技术有不同的需求，新一代通信技术的一个重要特点是要支持多种业务类型的灵活配置。在相关技术中，当终端配置了多个载波或一个载波上配置多个带宽部 分时，不同的载波或带宽部分使用相同的配置参数，但是当业务量增加且业务要求提高时，往往需要在不同的载波或带宽部分上使用不同的配置参数进行数据传输，因此，在不同的载波或带宽部分上使用不同的配置参数时，终端如何灵活地支持跨载波或跨带宽部分的调度进而实现数据传输成为研究的热点。为此，本公开实施例提供了一种数据传输方法，该数据传输方法解决了终端如何灵活地支持跨带宽部分调度的问题，其具体实现请参见如下图1B和图2A所示的实施例。
最后，对本公开实施例涉及的***架构进行简单介绍。
如图1A所示，该图1A是根据一示例性实施例提供的一种***架构的示意图。该***架构中主要包括终端110和基站120，该终端110可以通过无线通信网络接入该基站120中。
其中，该基站120主要用于向终端110发送配置信息、触发信令和调度信令，配置信息包括多个带宽部分的频域位置、支持的配置参数集合，以及包括的PRB的编号，触发信令用于指示跨带宽部分的调度已被触发，调度信令用于通知该终端110进行跨带宽部分调度。
其中，该终端110主要用于实现本公开实施例提供的数据传输方法，也即是，该终端110用于接收并存储基站120发送的配置信息，这里仅是以该配置信息是由该基站120发送给该终端110为例进行说明，在另一实施例中，该配置信息还可以是预先定义的，本公开实施例对此不做限定。另外，该终端110还用于接收基站120发送的触发信令，以触发跨带宽部分的调度。
进一步地，当终端110接收到基站120发送的调度信令时，根据该调度信令中携带的频域资源指示信息和预先存储的配置信息，在确定目标带宽部分不是被调度的带宽部分后再从多个带宽部分中确定该基站120所指示的被调度的带宽部分。进一步地，该终端110基于该调度信令中携带的参数指示信息对应的配置参数，通过被调度的带宽部分实现数据传输。其具体实现过程请参见如下图1B和图2A所示的实施例。
需要说明的是，在实际实现中，该终端110可以为一切能够用于进行无线通信的设备，例如，该终端110可以为手机等，本公开实施例对此不做限定。
在介绍完本公开实施例涉及的名词、应用场景和***架构后，下面将对本 公开实施例进行详细的解释说明。
图1B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，如图1B所示，该方法应用于终端中，该方法包括以下步骤。
在步骤101中，接收基站在目标带宽部分上发送的调度信令，该调度信令中携带频域资源指示信息和参数指示信息，目标带宽部分为已配置的多个带宽部分中能够传输该调度信令的任一带宽部分。
在步骤102中，当基于该频域资源指示信息和预先存储的配置信息确定目标带宽部分不是被调度的带宽部分时，基于该频域资源指示信息和该配置信息，从该多个带宽部分中确定被调度的带宽部分。
在步骤103中，按照该参数指示信息对应的配置参数，通过该被调度的带宽部分进行数据传输。
在本公开实施例中，为了实现多种类型业务的复用，终端需要灵活地支持跨带宽部分的调度进行数据传输。在实际实现中，由于该多个带宽部分中有的带宽部分上能够传输控制信息，而有的不能传输控制信息，因此，终端接收基站在目标带宽部分上发送的携带频域资源指示信息和参数指示信息的调度信令，并基于该频域资源指示信息，以及预先存储的配置信息，确定目标带宽部分是否为被调度的带宽部分。当目标带宽部分不是被调度的带宽部分时，终端需要基于该频域资源指示信息和该配置信息，从该多个带宽部分中确定被调度的带宽部分，之后，即可基于参数指示信息对应的配置参数并通过被调度的带宽部分进行数据传输，进而实现通过目标带宽部分上传输的调度信令来调度其他的带宽部分，从而实现跨带宽部分的调度。

可选地，调度信令是通过DCI的方式进行发送，该DCI中包括第一信息域，该第一信息域用于存放频域传输单元的指示信息；当参数指示信息为用于指示该配置参数的加扰序列时，该加扰序列是通过加扰在DCI上进行携带。
可选地，该频域资源指示信息还包括带宽编号指示信息。

可选地，该第二信息域位于该DCI中的第一预设位置上，该第三信息域位于该在DCI的第二预设位置上，且该第二信息域的长度为第一预设长度，该第三信息域的长度为第二预设长度。
可选地，该调度信令是通过下行控制信息DCI的方式进行发送，该DCI中包括第一信息域和第三信息域，该第一信息域用于存放频域传输单元的指示信息，第三信息域用于存放带宽编号指示信息；当参数指示信息为用于指示该配置参数的加扰序列时，该加扰序列是通过加扰在DCI上进行携带。
可选地，接收基站发送的调度信令之前，还包括：
接收并存储所述基站发送的配置信息，该配置信息中包括该多个带宽部分的频域位置、支持的配置参数集合，以及包括的PRB的编号。
可选地，该配置信息中还包括所述多个带宽部分的带宽编号。
可选地，接收基站发送的调度信令之前，还包括：
接收所述基站发送的触发信令，该触发信令用于指示跨带宽部分的调度已被触发。
上述所有可选技术方案，均可按照任意结合形成本公开的可选实施例，本公开实施例对此不再一一赘述。
图2A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，如图2A所示，该数据传输方法可以应用于图1A所示的***架构中，该数据传输方法可以包括以下几个实现步骤：
在步骤201中，接收并存储基站发送的配置信息，该配置信息中包括多个带宽部分的频域位置、支持的配置参数集合，以及包括的PRB的编号。
在实现本公开实施例之前，基站可以向终端发送该配置信息，相应地，终端接收该配置信息后，可以在本地存储该配置信息，以便于该终端后续可以基于该配置信息进行带宽部分的调度，具体请参见后续步骤。
需要说明的是，该配置信息可以由基站通过***信息、高层信令或者物理层信令发送给终端。其中，高层信令可以包括RRC(Radio Resource Control，无线资源控制)信令、MAC(Media Access Control Element，媒体接入控制)信令等。当然，实际应用中，也可以通过其他的方式来发送。
由于该配置信息中可以包含该多个带宽部分的频域位置、支持的配置参数集合，以及带宽部分包括的PRB的编号，且该配置信息用于在载波上配置该多个带宽部分，因此，在终端接收到该配置信息时，可以存储该配置信息，此时可以认为已配置该多个带宽部分。
值得注意的是，该多个带宽部分可以为同一载波上的带宽部分，当然，也可以为不同载波上的带宽部分，也即是，在后续调度时，可以通过同一载波上的带宽部分进行跨带宽部分的调度，也可以通过不同载波上的带宽部分进行跨带宽部分的调度。另外，该多个带宽部分在频域上可能是连续的，也可能是不连续的。
由于该多个带宽部分的PRB的编号可以按照顺序编号，即该多个带宽部分的PRB的编号不会存在重复的现象，例如，带宽部分1包括3个PRB，编号分别为1、2、3，带宽部分2包括2个PRB，编号分别为4、5，带宽部分3包括2个PRB，编号分别为6、7，带宽部分4包括3个PRB，编号分别为8、9、10。在这种情况下，终端可以通过PRB的编号明确地区分不同的带宽部分进而实现跨带宽调度。然而，实际应用中，该多个带宽部分的PRB的编号也可以不按照顺序编号，此时，该多个带宽部分的PRB的编号可能会出现重复的现象，例如，带宽部分1包括的3个PRB的编号分别为1、2、3，带宽部分2包括的2个PRB的编号分别为1、2，带宽部分3包括的2个PRB的编号分别为1、3，带宽部分4包括的3个PRB的编号分别为1、3、4。此时终端无法通过PRB的编号区分不同的带宽部分，因此，在这种情况下，基站向终端发送的配置信息中还可以包括该多个带宽部分的带宽编号，以便终端可以基于PRB的编号和带宽编号区分不同的带宽部分。
实际应用中，基站发送的配置信息中还可以包括该多个带宽部分的调度指示信息，该调度指示信息用于指示该多个带宽部分中哪些可以用来传输控制信息，哪些不能传输控制信息，这样，对于能够传输控制信息的带宽部分，这些带宽部分上不仅可以传输控制信息，也可以被调度来传输数据，而对于不能传输控制信息的带宽部分，这些带宽部分上只能通过其他能够传输控制信息的带宽部分上接收的调度信令被调度，以传输数据。这种现象被称为跨带宽部分的调度。
比如，如图2B所示，在一个载波上配置有4个带宽部分，分别为带宽部分1、带宽部分2、带宽部分3和带宽部分4。其中，通过配置信息中的调度指示信息可以确定带宽部分1和带宽部分3上可以用来传输控制信息，带宽部分2和带宽部分4上不能传输控制信息，这样，带宽部分2和带宽部分4可以通过带宽部分1或带宽部分3上传输的控制信息被调度，进而实现数据传输。
需要说明的是，本公开实施例仅是以该基站向终端发送该配置信息为例进行说明，在实际实现中，该配置信息还可以是预先定义的，本公开实施例对此不做限定。
当通过上述步骤201配置该多个带宽部分之后，当进行带宽部分的调度时，可以先通过如下步骤202来触发跨带宽部分的调度。
在步骤202中，接收基站发送的触发信令，该触发信令用于指示跨带宽部分的调度已被触发。
实际应用中，需要终端进行跨带宽部分调度的情况有很多，例如，业务量增加，即不同情况下，终端进行跨带宽调度的时机不同。因此当需要跨带宽部分的调度时，基站可以向终端发送触发信令，以通知终端进行跨带宽部分的调度，即该触发信令用于指示跨带宽部分的调度已被触发。
需要说明的是，该触发信令可以通过RRC信令、***信息、MAC信令或者物理层信令发送。
另外，上述步骤202并不是为了实现本公开实施例所必须的步骤，也即是，在本公开实施例中，当配置了该多个带宽部分之后，可以直接触发跨带宽部分的调度，此时，可以不用通过上述步骤202进行跨带宽部分的调度。
在步骤203中，接收基站在目标带宽部分上发送的调度信令，该调度信令中携带频域资源指示信息和参数指示信息，该目标带宽部分为已配置的多个带宽部分中能够传输调度信令的任一带宽部分。
如前文所述，基于配置信息，终端和基站均可以准确地获知该多个带宽部分的频域位置、支持的配置参数集合和包括的PRB编号。当基站需要调度带宽部分时，可以从该多个带宽部分中确定能够传输控制信息的目标带宽部分，此时，可以在目标带宽部分上发送调度信令。
需要说明的是，频域资源指示信息包括频域传输单元的指示信息，该频域传输单元为频域上传输信息的基本单元，包括一个或多个PRB，该频域传输单元的指示信息可以用于指示该一个或多个PRB的编号。进一步地，在该多个带宽部分的PRB的编号存在重复的情况下，该频域资源指示信息还可以包括带宽编号指示信息，该带宽编号指示信息用于指示被调度的带宽部分的带宽编号。另外，该参数指示信息用于指示被调度的带宽部分传输数据时所使用的配置参数，可选地，该参数指示信息可以为配置参数，也可以为用于指示配置参数的加扰序列。
另外，该调度信令是通过下行控制信息DCI的方式发送。当频域资源指示信息包括频域传输单元的指示信息时，由于DCI中原本就存在一个信息域用来存放频域传输单元的指示信息，也即是，DCI中的第一信息域用于存放频域传输单元的指示信息。此时，为了在DCI中携带参数指示信息，当该参数指示信息为配置参数时，可以在DCI定义一个信息域，即第二信息域，且第二信息域用于存放该配置参数。或者，当该参数指示信息为用于指示该配置参数的加扰序列时，该加扰序列是通过加扰在DCI上进行携带，也即是，该加扰序列可以加扰在DCI上，从而指示该配置参数。
进一步地，当频域资源指示信息包括频域传输单元的指示信息和带宽编号指示信息时，DCI中不仅可以上述信息域之外，还可以在DCI定义一个信息域，即第三信息域，且第三信息域用于存放带宽编号指示信息。
其中，第二信息域位于DCI中的第一预设位置上，且第二信息域的长度为第一预设长度，该第三信息域位于DCI的第二预设位置上，且第三信息域的长度为第二预设长度。
需要说明的是，第二信息域和第三信息域的长度可以为设置的固定的比特长度，当然，实际应用中，也可以按照实际情况进行配置。第二信息域和第三信息域的具体长度与终端配置的带宽部分的带宽编号以及支持的配置参数的数目有关，例如，终端支持4种配置参数，那么DCI中用于存放参数指示信息的第二信息域的长度可以为2比特，分别为“00”、“01”、“10”、“11”。
在步骤204中，当基于该频域资源指示信息和预先存储的配置信息确定目标带宽部分不是被调度的带宽部分时，基于该频域资源指示信息和该配置信息，从该多个带宽部分中确定被调度的带宽部分。
由前述论述可知，基站在目标带宽部分上发送的调度信令，有可能是为了调度目标带宽部分进行数据传输，当然，也有可能是为了在目标带宽部分上调度其他带宽部分进行数据传输。因此，在接收到基站在目标带宽部分上发送的调度信令时，可以基于该调度信令中的频域资源指示信息和预先存储的配置信息确定目标带宽是否为被调度的带宽部分，在目标带宽部分不是被调度的带宽部分时，再基于该频域资源指示信息和该配置信息，从该多个带宽部分中确定被调度的带宽部分。例如，如图2B所示，一个载波上配置了4个带宽部分，终端可以基于频域资源指示信息和预先存储的配置信息从这四个带宽部分中确定被调度的带宽部分。
由于在该多个带宽部分的PRB的编号不重复的情况下，配置信息中包括该多个带宽部分的频域位置、支持的配置参数集合，以及包括的PRB的编号，因此，可以将频域资源指示信息所指示的PRB的编号与目标带宽部分的PRB的编号进行比较，如果两者相同，则确定目标带宽部分为被调度的带宽部分，如果两者不同，则确定目标带宽部分不是被调度的带宽部分。在目标带宽不是被调度的带宽部分的情况下，可以基于该配置信息，从该多个带宽部分中选择PRB的编号与频域资源指示信息所指示的PRB的编号相同的带宽部分，并将选择的带宽部分确定为被调度的带宽部分。
同理，在该多个带宽部分的PRB的编号存在重复的情况时，配置信息中包括该多个带宽部分的频域位置、支持的配置参数集合，以及包括的PRB的编号和带宽编号，因此，可以将频域资源指示信息所指示的PRB的编号和带宽编号指示信息所指示的带宽编号分别与目标带宽部分的PRB的编号和带宽编号进行比较，如果均相同，则确定目标带宽部分为被调度的带宽部分，如果存在不同，则确定目标带宽部分不是被调度的带宽部分。在目标带宽不是被调度的带宽部分的情况下，可以基于该配置信息，从该多个带宽部分中选择PRB的编号和带宽编号均与频域资源指示信息所指示的PRB的编号和带宽编号指示信息所指示的带宽编号相同的带宽部分，并将选择的带宽部分确定为被调度的带宽部分。
在步骤205中，按照该参数指示信息对应的配置参数，通过被调度的带宽 部分进行数据传输。
基于前文的描述，配置信息中包括该多个带宽部分所支持的配置参数集合，也即是，每个带宽部分可能会支持多种配置参数，而该参数指示信息对应的配置参数可能是该多种配置参数中的一种，因此，在确定被调度的带宽部分之后，可以按照该参数指示信息对应的配置参数，在被调度的带宽部分的频域位置上传输数据。
另外，上述提到参数指示信息可以为配置参数，也可以为用于指示配置参数的加扰序列，因此，在参数指示信息为用于指示配置参数的加扰序列时，需要基于该加扰序列，从预先存储的加扰序列与配置参数之间的对应关系中获取对应的配置参数，然后再按照获取的配置参数，在被调度的带宽部分的频域位置上传输数据。
需要说明的是，加扰序列与配置参数之间的对应关系可以是基站通过***信令、RRC信令、MAC信令或者物理层信令发送给终端，当然，也可以预先定义得到，本公开实施例对此不做限定。
在本公开实施例中，为了实现多种类型业务的复用，终端需要灵活地支持跨带宽部分的调度进行数据传输。在实际实现中，由于该多个带宽部分中，有的带宽部分上能够传输控制信息，而有的不能传输控制信息，因此，终端接收基站在目标带宽部分上发送的携带频域资源指示信息和参数指示信息的调度信令，并基于该频域资源指示信息，以及预先存储的配置信息，确定目标带宽部分是否为被调度的带宽部分。当目标带宽部分不是被调度的带宽部分时，终端需要基于该频域资源指示信息和该配置信息，从该多个带宽部分中确定被调度的带宽部分，之后，即可基于参数指示信息对应的配置参数并通过被调度的带宽部分进行数据传输，进而实现通过目标带宽部分上传输的调度信令来调度其他的带宽部分，从而实现跨带宽部分的调度。

在本公开实施例中，为了实现多种类型业务的复用，终端需要灵活地支持跨带宽部分的调度进行数据传输。在实际实现中，由于该多个带宽部分中有的带宽部分上能够传输控制信息，而有的不能传输控制信息，因此，终端接收基站在目标带宽部分上发送的携带频域资源指示信息和参数指示信息的调度信令，并基于该频域资源指示信息，以及预先存储的配置信息，确定目标带宽部分是否为被调度的带宽部分。当目标带宽部分不是被调度的带宽部分时，终端需要基于该频域资源指示信息和该配置信息，从该多个带宽部分中确定被调度的带宽部分，之后，即可基于参数指示信息对应的配置参数并通过被调度的带宽部分进行数据传输，进而实现通过目标带宽部分上传输的调度信令来调度其他的带宽部分，从而实现跨带宽部分的调度。
