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(Long Term Evolution，长期演进)系统中的动态调度来说，一个调度信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，用于传输控制信令，这里的控制信令包括调度信令，以指示终端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，即调度信令的箭头所指示的时频资源，用于供终端进行数据传输。
非授权频段是竞争使用的频段。多个不同制式的通信系统可以竞争使用非授权频段上的频域资源。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段上的频域资源。若LTE系统中为终端分配的时频资源是非授权频段上的时频资源，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，即使通过调度信令为终端分配了一个时频资源，终端可能并不能成功占用该时频资源，导致终端无法在该时频资源上进行数据传输。请参考图2，其示出了非授权频段的资源分配的示意图，其中，阴影区域是调度信令，白色填充区域是时频资源，调度信令的箭头指向的是分配给终端的一个时频资源，终端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，终端无法占用该时频资源。当监听到该信道未被占用，即LBT成功时，终端可以占用该时频资源。
相关技术中，接入网设备与终端可以在固定的空闲时域单元传输数据包。 其中，当时间窗口和空闲时域单元的位置固定时，该传输单元所包括的空闲时域单元的数量也固定。假设时间窗口是一个包括14个符号的时隙，时域单元是符号，且该固定的空闲时域单元的位置是第8个符号的位置，则一个传输单元固定包括7个符号。当接入网设备在第6个符号占用了信道资源时，可以在第7个符号上向终端发送调度指示，通过调度指示来指示终端与接入网设备在第8-14个符号上传输数据包。若接入网设备在第1-5个符号占用了信道资源，则仍然需要指示终端与接入网设备在第8-14个符号上传输数据包，其余符号未被用于承载数据包，导致信道资源的浪费。若接入网设备在第7-14个符号占用了信道资源，则需要指示终端与接入网设备在下个时隙的第8-14个符号上传输数据包，导致数据的传输效率较低。
本实施例中，可以预定义不同时域长度的传输单元，这里所说的传输单元的时域长度是指传输单元所包括的时域单元的数量，再根据时间窗口内空闲时域单元的数量对各个传输单元进行组合，使得空闲时域单元的数量大于等于所有传输单元包括的时域单元的数量之和。这样，无论时间窗口内存在多少空闲时域单元，都可以按照预定义的传输单元的时域长度对空闲时域单元进行组合得到至少一个传输单元。由于传输单元用于承载数据包传输，所以，既解决了只能在固定的空闲时域单元上传输数据包时，若成功占用的空闲时域单元早于该固定的空闲时域单元，则仍然需要等到在该固定的空闲时域单元上传输数据包，浪费了信道资源的问题，达到了节省信道资源的效果。也解决了只能在固定的空闲时域单元上传输数据包时，若未成功占用该空闲时域单元，则接入网设备与终端需要等到下个时间窗口内再传输数据包，导致数据的传输效率较低的问题，达到了提高数据传输效率的效果。
需要说明的是，在配置好传输单元后，接入网设备与终端之间可以传输数据包，该传输过程可以包括：接入网设备向终端发送下行数据包，以及，终端向接入网设备发送上行数据包，下文不再赘述。
图3示出了本公开一个实施例提供的移动通信系统的结构示意图。该移动通信系统可以是5G系统，又称NR(New Radio，新空口)系统。该移动通信系统包括：接入网设备301和终端302。
接入网设备301可以是基站。例如，基站可以是5G系统中采用集中分布式架构的基站(gNB)。当接入网设备301采用集中分布式架构时，通常包括 集中单元(Central Unit，CU)和至少两个分布单元(Distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本申请实施例对接入网设备301的具体实现方式不加以限定。可选地，接入网设备301还可以包括家庭基站(Home eNB，HeNB)、中继(Relay)、微微基站Pico等。
接入网设备301和终端302通过无线空口建立无线连接。可选地，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口(New Radio，NR)；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
终端302可以是指向用户提供语音和/或数据连通性的设备。终端302可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端302可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置。例如，订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户装置(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户终端(User Equipment)。
需要说明的是，在图3所示的移动通信系统中，可以包括多个接入网设备301和/或多个终端302，图3中以示出一个接入网设备301和一个终端302来举例说明，但本实施例对此不作限定。
图4是根据一示例性实施例示出的一种传输配置方法的流程图，该传输配置方法应用于图3所示的移动通信系统中，如图4所示，该传输配置方法包括以下步骤。
在步骤401中，接入网设备确定非授权频段的时间窗口内的空闲时域单元。
在步骤402中，接入网设备按照预定义的传输单元的时域长度对空闲时域单元进行组合得到至少一个传输单元。
其中，该传输单元用于承载数据包传输，该传输单元的时域长度用于指示 传输单元包含的时域单元的数量。
在步骤403中，接入网设备向终端发送调度指示，该调度指示用于指示至少一个传输单元。
在步骤404中，终端接收接入网设备发送的调度指示。
在步骤405中，终端根据该调度指示确定该至少一个传输单元。
其中，步骤401-403可以单独实现成为接入网设备侧的实施例，步骤404-405可以单独实现成为终端侧的实施例。
综上所述，本公开提供的传输配置方法，通过预定义不同时域长度的传输单元，这里所说的传输单元的时域长度是指传输单元所包括的时域单元的数量。这样，无论时间窗口内存在多少空闲时域单元，都可以按照预定义的传输单元的时域长度对空闲时域单元进行组合得到至少一个传输单元。由于传输单元用于承载数据包传输，所以，既解决了只能在固定的空闲时域单元上传输数据包时，若成功占用的空闲时域单元早于该固定的空闲时域单元，则仍然需要等到在该固定的空闲时域单元上传输数据包，浪费了信道资源的问题，达到了节省信道资源的效果。也解决了只能在固定的空闲时域单元上传输数据包时，若未成功占用该空闲时域单元，则接入网设备与终端需要等到下个时间窗口内再传输数据包，导致数据的传输效率较低的问题，达到了提高数据传输效率的效果。
图5是根据另一示例性实施例示出的一种传输配置方法的流程图，该传输配置方法应用于图3所示的移动通信系统中，如图5所示，该传输配置方法包括如下步骤。
在步骤501中，接入网设备确定非授权频段的时间窗口内的空闲时域单元。
时间窗口是时域上的概念，且一个时间窗口内包含至少两个时域单元。在一种可能的实现方式中，时间窗口是一个时隙，则时域单元可以是一个符号，此时一个时间窗口内可以包含14个时域单元。
时间窗口内的空闲时域单元是指在接入网设备成功占用信道资源后，该时间窗口内剩余的可以用于承载数据传输的时域单元。比如，接入网设备在第6个符号占用了信道资源时，可以在第7个符号上向终端发送调度信令，则剩余的用于承载数据传输的时域单元为第8-14个符号，则可以将第8-14个符号称为时间窗口内的空闲时域单元。
在步骤502中，接入网设备按照预定义的传输单元的时域长度对空闲时域单元进行组合得到至少一个传输单元，该传输单元用于承载数据包传输，该传输单元的时域长度用于指示传输单元包含的时域单元的数量。
预定义的传输单元的时域长度可以不同。比如，预定义的一个传输单元的时域长度是1个符号、一个传输单元的时域长度是2个符号，一个传输单元的时域长度是3个符号等等。
本实施例中，可以通过时域长度指示来指示传输单元的时域长度。在一种实现方式中，可以在接入网设备中预定义该时域长度指示，接入网设备可以直接从接入网设备中读取该时域长度指示，再根据该时域长度指示确定预定义的传输单元的时域长度。
为了便于理解，这里所说的传输单元可以理解成用于承载数据包传输的容器。比如，包含1个符号的传输单元可以承载时域上1个符号的数据包，包含2个符号的传输单元可以承载时域上2个符号的数据包，包含3个符号的传输单元可以承载时域上3个符号的数据包。
本实施例中，接入网设备在获取到空闲时域单元的数量以及至少一个传输单元的时域长度后，可以根据该数量以及传输单元的时域长度，对空闲时域单元进行组合，得到至少一个传输单元。此时，每个传输单元包含至少一个空闲时域单元，且时间窗口内的空闲时域单元的数量大于等于所有传输单元包含的空闲时域单元的数量之和。假设时域单元为符号，且空闲的符号的数量为7，则接入网设备可以组合得到两个包含2个符号的传输单元和一个包含3个符号的传输单元；假设空闲符号的数量为5，则接入网设备可以组合得到一个包括2个符号的传输单元和一个包括3个符号的传输单元，请参考图6。
在步骤503中，接入网设备向终端发送调度指示，该调度指示用于指示至少一个传输单元。
在确定了传输单元后，接入网设备需要生成用于指示传输单元的调度指示，并向终端发送该调度指示。在一种可能的实现方式中，接入网设备可以向终端发送携带有该调度指示的调度信令。
在接入网设备与终端之间传输数据包时，若该接入网设备在一个调度信令中调度了一个数据包，该数据包可以在连续的空闲时域单元上传输，也可以在不连续的空闲时域单元上传输。或者，若该接入网设备在一个调度信令中调度了多个数据包，则每个数据包在连续的空闲时域单元上传输，不同的数据包可 以在连续或是不连续的空闲时域单元上传输。下面分别对不同的数据包在连续或是不连续的空闲时域单元上传输的这两种应用场景进行介绍。
1)在第一种实现方式中，一个数据包在连续的空闲时域单元上传输，不同的数据包在连续的空闲时域单元上传输，也即，所有相邻的传输单元包含的空闲时域单元之间连续，此时若传输单元以传输数据包的时域起始位置表示，则调度指示用于指示该时域起始位置。
由于每个数据包都在连续的空闲时域单元上传输，所以，接入网设备可以根据组合得到的各个传输单元以及每个数据包的长度确定每个数据包的时域起始位置，并生成用于指示时域起始位置的调度指示。其中，一个数据包可以承载在一个传输单元中的传输，也可以承载在至少两个传输单元中传输，本实施例不作限定。
假设空闲时域单元为第8-14个符号，根据终端的业务需求组合得到的传输单元是两个包含2个符号的传输单元和一个包含3个符号的传输单元；若第一个数据包占用2个符号、第二个数据包占用2个符号，第三个数据包占用3个符号，则调度指示所指示的这三个数据包的时域起始位置分别为第8个符号、第10个符号和第12个符号。若第一个数据包占用4个符号，第二个数据包占用3个符号，则调度指示所指示的这两个数据包的时域起始位置分别为第8个符号和第12个符号。
2)在第二种实现方式中，一个数据包在连续的空闲时域单元上传输，不同的数据包在连续的空闲时域单元上传输，也即，所有相邻的传输单元包含的空闲时域单元之间连续。或者，一个数据包在连续的空闲时域单元上传输，不同的数据包在不连续的空闲时域单元上传输，也即，存在至少一组相邻的传输单元包含的空闲时域单元之间不连续，此时若传输单元以传输数据包的时域起始位置以及数据包所占用的时域资源长度表示，则调度指示用于指示时域起始位置和时域资源长度。
接入网设备可以根据组合得到的各个传输单元以及每个数据包的长度确定每个数据包的时域起始位置和每个数据包所占用的时域资源长度，并生成用于指示时域起始位置和时域资源长度的调度指示。其中，一个数据包可以承载在一个传输单元中的传输，也可以承载在至少两个传输单元中传输，本实施例不作限定。
假设空闲时域单元为第8-14个符号，根据终端的业务需求组合得到的传 输单元是三个包含2个符号的传输单元；若第一个数据包占用2个符号、第二个数据包占用2个符号，第三个数据包占用2个符号，则调度指示所指示的第一个数据包的时域起始位置为第8个符号，时域资源长度为2个符号；调度指示所指示的第二个数据包的时域起始位置为第11个符号，时域资源长度为2个符号；调度指示所指示的第三个数据包的时域起始位置为第13个符号，时域资源长度为2个符号。若第一个数据包占用4个符号、第二个数据包占用2个符号，则调度指示所指示的第一个数据包的时域起始位置为第8个符号，时域资源长度为4个符号；调度指示所指示的第二个数据包的时域起始位置为第13个符号，时域资源长度为2个符号。
3)在第三种实现方式中，一个数据包在连续的空闲时域单元上传输，不同的数据包在连续的空闲时域单元上传输，也即，所有相邻的传输单元包含的空闲时域单元之间连续。或者，一个数据包在连续的空闲时域单元上传输，不同的数据包在不连续的空闲时域单元上传输，也即，存在至少一组相邻的传输单元包含的空闲时域单元之间不连续，此时若传输单元以传输数据包的时域起始位置以及传输单元的时域长度表示，则调度指示用于指示时域起始位置，接入网设备向终端发送的时域长度指示用于指示传输单元的时域长度。
接入网设备可以根据组合得到的各个传输单元以及每个数据包的长度确定每个数据包的时域起始位置和承载每个数据包的传输单元的时域长度，并生成用于指示时域起始位置的调度指示。其中，一个数据包可以承载在一个传输单元中的传输，也可以承载在至少两个传输单元中传输，本实施例不作限定。
假设空闲时域单元为第8-14个符号，根据终端的业务需求组合得到的传输单元是三个包含2个符号的传输单元；若第一个数据包占用2个符号、第二个数据包占用2个符号，第三个数据包占用2个符号，则调度指示所指示的第一个数据包的时域起始位置为第8个符号，时域长度指示所指示的传输单元的时域长度为2个符号；调度指示所指示的第二个数据包的时域起始位置为第11个符号，时域长度指示所指示的传输单元的时域长度为2个符号；调度指示所指示的第三个数据包的时域起始位置为第13个符号，时域长度指示所指示的传输单元的时域长度为2个符号。若第一个数据包占用4个符号、第二个数据包占用2个符号，则调度指示所指示的第一个数据包的时域起始位置为第8个符号，时域长度指示所指示的传输单元的时域长度为4个符号；调度指示所指示的第二个数据包的时域起始位置为第13个符号，时域长度指示所指示的传 输单元的时域长度为2个符号。
需要说明的是，接入网设备可以先向终端发送时域长度指示，再向终端发送调度指示。
4)在第四种实现方式中，一个数据包在连续的空闲时域单元上传输，不同的数据包在连续的空闲时域单元上传输，也即，所有相邻的传输单元包含的空闲时域单元之间连续。或者，一个数据包在连续的空闲时域单元上传输，不同的数据包在不连续的空闲时域单元上传输，也即，存在至少一组相邻的传输单元包含的空闲时域单元之间不连续，此时若传输单元以传输数据包的时域起始位置以及传输单元的时域长度表示，则调度指示用于指示时域起始位置，且终端用于根据终端中预定义的时域长度指示确定传输单元的时域长度。
第四种实现方式与第三种实现方式类似，区别在于，第四种实现方式中，终端中预定义有传输单元的时域长度，则接入网设备可以不向终端发送时域长度指示。
假设空闲时域单元为第8-14个符号，根据终端的业务需求组合得到的传输单元是三个包含2个符号的传输单元；若第一个数据包占用2个符号、第二个数据包占用2个符号，第三个数据包占用2个符号，则调度指示所指示的第一个数据包的时域起始位置为第8个符号；调度指示所指示的第二个数据包的时域起始位置为第11个符号；调度指示所指示的第三个数据包的时域起始位置为第13个符号。若第一个数据包占用4个符号、第二个数据包占用2个符号，则调度指示所指示的第一个数据包的时域起始位置为第8个符号；调度指示所指示的第二个数据包的时域起始位置为第13个符号。
在步骤504中，终端接收接入网设备发送的调度指示。
在步骤505中，终端根据该调度指示确定该至少一个传输单元。
对应于上述四种调度指示，下面分别对终端确定传输单元的实现方式进行介绍。
1)对应于上述第一种实现方式，调度指示所指示的是时域起始位置，终端确定一个数据包在连续的时域单元上传输，且不同的数据包在连续的时域单元上传输，也即，所有相邻的传输单元包含的空闲时域单元之间连续。此时，终端可以根据时域起始位置确定传输单元。
假设调度指示所指示的三个数据包的时域起始位置分别为第8个符号、第10个符号和第12个符号，则终端可以确定承载第一个数据包传输的传输单元 的时域长度为2个符号，且该传输单元包含第8-9个符号；承载第二个数据包传输的传输单元的时域长度为2个符号，且该传输单元包含第10-11个符号；承载第三个数据包传输的传输单元的时域长度为3个符号，且该传输单元包含第12-14个符号。假设调度指示所指示的两个数据包的时域起始位置分别为第8个符号和第12个符号，则终端可以确定承载第一个数据包传输的传输单元的时域长度为4个符号，且该传输单元包含第8-11个符号；承载第二个数据包传输的传输单元的时域长度为3个符号，且该传输单元包含第12-14个符号。
2)对应于上述第二种实现方式，调度指示所指示的是时域起始位置和时域资源长度，终端确定一个数据包在连续的时域单元上传输，且不同的数据包在连续的时域单元上传输，也即，所有相邻的传输单元包含的空闲时域单元之间连续。或者，终端确定一个数据包在连续的时域单元上传输，且不同的数据包在不连续的时域单元上传输也即，存在至少一组相邻的传输单元包含的空闲时域单元之间不连续。此时，终端可以根据时域起始位置和时域资源长度确定传输单元。
假设调度指示所指示的第一个数据包的时域起始位置为第8个符号，时域资源长度为2个符号，则终端可以确定承载第一个数据包的传输单元包含第8-9个符号；调度指示所指示的第二个数据包的时域起始位置为第11个符号，时域资源长度为2个符号，则终端确定承载第二个数据包的传输单元包含第11-12个符号；调度指示所指示的第三个数据包的时域起始位置为第13个符号，时域资源长度为2个符号，则终端确定承载第三个数据包的传输单元包含第13-14个符号。假设调度指示所指示的第一个数据包的时域起始位置为第8个符号，时域资源长度为4个符号，则终端确定承载第一个数据包的传输单元包含第8-11个符号；调度指示所指示的第二个数据包的时域起始位置为第13个符号，时域资源长度为2个符号，则终端确定承载第二个数据包的传输单元包含第13-14个符号。
3)对应于上述第三种实现方式，调度指示所指示的是时域起始位置，时域长度指示所指示的是传输单元的时域长度，终端确定一个数据包在连续的时域单元上传输，且不同的数据包在连续的时域单元上传输，也即，所有相邻的传输单元包含的空闲时域单元之间连续。或者，终端确定一个数据包在连续的时域单元上传输，且不同的数据包在不连续的时域单元上传输也即，存在至少一组相邻的传输单元包含的空闲时域单元之间不连续。此时，终端可以根据时 域起始位置和传输单元的时域长度确定传输单元。
假设调度指示所指示的第一个数据包的时域起始位置为第8个符号，且时域长度指示所指示的传输单元的时域长度为2个符号，则终端可以确定承载第一个数据包的传输单元包含第8-9个符号；调度指示所指示的第二个数据包的时域起始位置为第11个符号，且时域长度指示所指示的传输单元的时域长度为2个符号，则终端可以确定承载第二个数据包的传输单元包含第11-12个符号；调度指示所指示的第三个数据包的时域起始位置为第13个符号，且时域长度指示所指示的传输单元的时域长度为2个符号，则终端可以确定承载第三个数据包的传输单元包含第13-14个符号。假设调度指示所指示的第一个数据包的时域起始位置为第8个符号，且时域长度指示所指示的传输单元的时域长度为4个符号，则终端可以确定承载第一个数据包的传输单元包含第8-11个符号；调度指示所指示的第二个数据包的时域起始位置为第11个符号，且时域长度指示所指示的传输单元的时域长度为2个符号，则终端可以确定承载第二个数据包的传输单元包含第13-14个符号。
4)对应于上述第四种实现方式，调度指示所指示的是时域起始位置，终端确定一个数据包在连续的时域单元上传输，且不同的数据包在连续的时域单元上传输，也即，所有相邻的传输单元包含的空闲时域单元之间连续。或者，终端确定一个数据包在连续的时域单元上传输，且不同的数据包在不连续的时域单元上传输也即，存在至少一组相邻的传输单元包含的空闲时域单元之间不连续。此时，终端还需要获取传输单元的时域长度，根据时域起始位置和传输单元的时域长度确定传输单元。
在确定传输单元之前，终端还需要获取时域长度指示，再根据时域长度指示确定传输单元的时域长度。其中，当终端中预定义该时域长度指示时，终端可以直接从终端中读取该时域长度指示，再根据该时域长度指示确定预定义的传输单元的时域长度。当终端中未预定义该时域长度指示时，终端可以接收接入网设备发送的时域长度指示，再根据该时域长度指示确定预定义的传输单元的时域长度。
假设时域长度指示所指示的传输单元的时域长度为2个符号，调度指示所指示的三个数据包的时域起始位置分别为第8个符号、第11个符号和第13个符号，则终端可以确定承载第一个数据包的传输单元包含第8-9个符号，承载第二个数据包的传输单元包含第11-12个符号，承载第三个数据包的传输单元 包含第13-14个符号。假设时域长度指示所指示的传输单元的时域长度分别为4个符号和2个符号，调度指示所指示的两个数据包的时域起始位置分别为第8个符号和第13个符号，则终端确定承载第一个数据包的传输单元包含第8-11个符号，承载第二个数据包的传输单元包含第13-14个符号。
其中，步骤501-503可以单独实现成为接入网设备侧的实施例，步骤504-505可以单独实现成为终端侧的实施例。
综上所述，本公开提供的传输配置方法，通过预定义不同时域长度的传输单元，这里所说的传输单元的时域长度是指传输单元所包括的时域单元的数量。这样，无论时间窗口内存在多少空闲时域单元，都可以按照预定义的传输单元的时域长度对空闲时域单元进行组合得到至少一个传输单元。由于传输单元用于承载数据包传输，所以，既解决了只能在固定的空闲时域单元上传输数据包时，若成功占用的空闲时域单元早于该固定的空闲时域单元，则仍然需要等到在该固定的空闲时域单元上传输数据包，浪费了信道资源的问题，达到了节省信道资源的效果。也解决了只能在固定的空闲时域单元上传输数据包时，若未成功占用该空闲时域单元，则接入网设备与终端需要等到下个时间窗口内再传输数据包，导致数据的传输效率较低的问题，达到了提高数据传输效率的效果。
图7是根据另一示例性实施例示出的一种传输配置方法的流程图，该传输配置方法应用于图3所示的移动通信系统中，如图7所示，该传输配置方法包括如下步骤。
在步骤701中，接入网设备确定非授权频段的时间窗口内的空闲时域单元。
在步骤702中，接入网设备按照预定义的传输单元的时域长度对空闲时域单元进行组合得到至少一个传输单元，该传输单元用于承载数据包传输，该传输单元的时域长度用于指示传输单元包含的时域单元的数量。
其中，步骤701-702的实现流程详见步骤501-502中的描述，此处不作赘述。
在步骤703中，接入网设备获取时域资源指示与调度指示之间的对应关系。
时域资源指示用于指示至少一个传输单元的时域长度。比如，接入网设备可以定义一条时域资源指示用于指示两个传输单元的时域长度分别是：2个符号、3个符号；一条时域资源指示用于指示三个传输单元的时域长度分别是：2 个符号、3个符号、3个符号；一条时域资源指示用于指示三个传输单元的时域长度分别是：3个符号、3个符号、2个符号。
接入网设备还可以生成时域资源指示和调度指示之间的对应关系，这里所说的调度指示可以理解成时域资源指示的索引。以上述例举的3条时域资源指示为例，则请参考下表一所示的对应关系。
表一
调度指示 时域资源指示
1 2个符号、3个符号
2 2个符号、3个符号、3个符号
3 3个符号、3个符号、2个符号
上述表一中的对应关系是一种示例，在实际实现时，接入网设备可以根据实际需求定义其他对应关系，本实施例不作限定。
由于终端也需要获取该对应关系，所以，当终端中未预定义该对应关系时，接入网设备需要向终端发送该对应关系。当终端中预定义有该对应关系时，终端可以直接从终端中读取该对应关系，接入网设备无需向终端发送该对应关系。
在步骤704中，接入网设备确定用于指示至少一个传输单元的时域长度的第一时域资源指示。
接入网设备可以在步骤702中组合得到至少一个传输单元后，根据该至少一个传输单元的时域长度生成第一时域资源指示。假设空闲时域单元为第7-14个符号，根据终端的业务需求组合得到的传输单元是一个包含2个符号的传输单元和两个包含3个符号的传输单元，则第一时域资源指示为：2个符号、3个符号、3个符号。
为了便于区分，本实施例中将用于指示实际的传输单元的时域资源指示称为第一时域资源指示，该第一资源指示的内容可以与对应关系中任一条时域资源指示的内容相同。
在步骤705中，接入网设备在该对应关系中查找与第一时域资源指示对应的调度指示。
以步骤704中的第一时域资源指示为例，则接入网设备查找到的调度指示为2。
在步骤706中，接入网设备向终端发送调度指示，该调度指示用于指示传 输单元。
在步骤707中，终端接收接入网设备发送的调度指示。
在步骤708中，终端获取调度指示和时域资源指示之间的对应关系。
当终端中未预定义该对应关系时，接入网设备会向终端发送该对应关系，则终端接收接入网设备发送的该对应关系。当终端中预定义有该对应关系时，终端可以直接读取该对应关系。
在步骤709中，终端在该对应关系中查找与接收到的调度指示对应的第一时域资源指示，确定该第一时域资源指示所指示的至少一个传输单元的时域长度，根据该至少一个传输单元的时域长度确定该至少一个传输单元。
在获取到对应关系后，终端可以在该对应关系中查找与该调度指示对应的第一时域资源指示。比如，调度指示为2，则终端查找到的第一时域资源指示用于指示：2个符号、3个符号、3个符号。
在确定至少一个传输单元的时域长度后，终端可以将传输该调度指示的后一个符号作为时域起始位置，根据该时域起始位置和该至少一个传输单元的时域长度确定该至少一个传输单元。此时所有相邻的传输单元包含的空闲时域单元之间连续。
假设时域起始位置为第7个符号，则第一个传输单元包含第7-8个符号，第二个传输单元包含第9-11个符号，第三个传输单元包含第12-14个符号。
其中，步骤701-706可以单独实现成为接入网设备侧的实施例，步骤707-709可以单独实现成为终端侧的实施例。
综上所述，本公开提供的传输配置方法，通过预定义不同时域长度的传输单元，这里所说的传输单元的时域长度是指传输单元所包括的时域单元的数量。这样，无论时间窗口内存在多少空闲时域单元，都可以按照预定义的传输单元的时域长度对空闲时域单元进行组合得到至少一个传输单元。由于传输单元用于承载数据包传输，所以，既解决了只能在固定的空闲时域单元上传输数据包时，若成功占用的空闲时域单元早于该固定的空闲时域单元，则仍然需要等到在该固定的空闲时域单元上传输数据包，浪费了信道资源的问题，达到了节省信道资源的效果。也解决了只能在固定的空闲时域单元上传输数据包时，若未成功占用该空闲时域单元，则接入网设备与终端需要等到下个时间窗口内再传输数据包，导致数据的传输效率较低的问题，达到了提高数据传输效率的效果。
