传输调度方法、装置、通信设备及存储介质 技术领域
本申请涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及一种传输调度方法、装置、通信设备及存储介质。
背景技术
新一代的增强现实(AR，Augmented Reality)、虚拟现实(VR，Virtual Reality)、车车通信等新型互联网应用技术的不断涌现，对无线通信技术提出了更高的要求，驱使无线通信技术的不断演进以满足应用的需求。蜂窝移动通信技术正处于新一代技术的演进阶段。新一代技术的一个重要特点就是要支持多种业务类型的灵活配置。不同的业务类型对于无线通信技术有不同的要求。例如，增强移动宽带(eMBB，Enhanced Mobile Broadband)业务类型要求主要侧重大带宽、高速率等要求；低时延高可靠通信(URLLC，Ultra Reliable Low Latency Communication)业务类型主要侧重较高的可靠性以、低时延等要求；海量机器类通信(mMTC，massive Machine Type Communication)业务类型主要侧重大量的连接数等要求。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。
随着新的无线通信技术的应用，分配给已存在的通信技术的频率资源可能会逐渐被分配给新的通信技术使用。因此，会存在多种蜂窝通信技术共存的场景。例如，5G新空口(NR，New Radio)系统以及LTE系统工作在同一段频域资源上。在LTE系统和5G新空口系统共存的频段上，为了保证LTE系统的正常工作，LTE系统的信道需要占用的资源会被预留出来。在这种情况下，能够提供给5G新空口系统使用的资源就会比较少，5G新空口系统需要的资源就会受到限制。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统， 该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11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11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、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、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，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12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，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，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；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。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户网络侧设备(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
为了更好地理解本公开任一个实施例所描述的技术方案，首先，通过一个实施例对多种通信系统共存的场景进行说明。
如图2所示，本公开一个实施例提供了一种LTE系统和5G新空口系统共存的场景。在LTE系统和5G新空口系统共存的频段上，为了确保LTE系统的正常运行，LTE系统信道需要占用的资源会预留出来。例如，图2中的LTE下行公共导频区域、图2中的LTE控制区域。在这种情况下，能够供5G新空口系统使用的资源就会比较少。
在一个实施例中，基于载波聚合技术可以实现一个小区内的调度指令调度别的小区内的数据传输。然而，在该实施例中，一个调度指令只能调度一个小区内的数据传输。针对LTE系统与5G新空口系统共存的场景，并不能解决5G新空口系统控制资源受限的问题。
如图3所示，本公开一个实施例提供了一种传输调度方法，该方法包括：
步骤S310：在第一小区内下发一个调度在至少两个第二小区内进行数据传输的下行控制信息DCI。
在一个实施例中，基站在向UE下发下行控制信息(DCI，Downlink Control Information)时，首先，UE接收基站发送的下行控制信息DCI。下行控制信息DCI用于指示UE如下至少之一：如何接收基站发送的下行数据、如何向基站发送上行数据、如何调整发射功率；其次，UE在接收了下行控制信息DCI之后，再根据下行控制信息DCI的指示进行数据传输。这里，数据传输可以是向基站发送上行数据，也可以是接收基站发送的下行数据。
在一个实施例中，每个小区都可以配置有一个载波。不同的小区采用不同的载波实现小区内无线信号的覆盖，完成小区内的数据传输。例如，A小区采用载波1实现小区内无线信号的覆盖；B小区采用载波2实现小区内无线信号的覆盖。
在一个实施例中，第二小区可以是与第一小区不同的小区。例如，第 一小区为A小区，两个第二小区分别为B小区和C小区。在另一个实施例中，第二小区可以包括第一小区。例如，第一小区为A小区，两个第二小区分别为A小区和B小区。
本公开实施例中，通过在第一小区内下发一个所述DCI就可以实现调度在至少两个所述第二小区内进行数据传输，相比一个DCI只能调度在一个小区内进行数据传输的情况，可以有效地降低无线通信过程中控制信令的开销，提高无线资源的利用率。
如图4所示，本公开另一个实施例提供了一种传输调度方法，在步骤S310中，在第一小区内下发一个调度在至少两个第二小区内进行数据传输的下行控制信息DCI，包括：
步骤S410，当调度在至少两个第二小区内进行数据传输时，在第一小区内下发携带有调度信息域的DCI，其中，调度信息域，携带有调度在至少两个第二小区内进行数据传输的指示信息。
在一个实施例中，指示信息可以包括第二小区的标识信息。
在一个实施例中，调度信息域位于DCI的固定位置；
和/或，
调度信息域的信息域长度为固定长度。
在一个实施例中，DCI占用N个比特位，各比特位的编号依次为第1至第N，则调度信息域可以在该N个比特位中占用编号为第Q至第P的比特位。其中，N>P>Q>0，N、P、Q为正整数。这里，N、P、Q可以设定为固定值。此时，调度信息域位于DCI的固定位置，且调度信息域的信息域长度为固定长度。例如，N＝12；P＝6；Q＝3；则调度信息域位于DCI所占比特位的编号为第3至第6的比特位的固定位置，且调度信息域的信息域长度为4。
这里，由于调度信息域位于DCI的固定位置和/或调度信息域的信息域 长度为固定长度，当UE接收到DCI后，能够快速准确地定位调度信息域在DCI中的位置和并确定调度信息域的长度，从调度信息域中获取调度信息域携带的调度在至少两个第二小区内进行数据传输的指示信息。如此，调度信息域位于DCI的固定位置和/或调度信息域的信息域长度为固定长度，能够简化DCI解码，提升解码效率。
在一个实施例中，基站可以预先将调度信息域位于DCI的固定位置的信息和/或调度信息域的信息域长度的信息发送给UE。
在另一个实施例中，UE通过预先定义的方法获知调度信息域的位置和/或长度信息。例如，可以在通信协议中预先设定DCI中调度信息域的位置和/或长度，终端根据通信时采用的通信协议类型就可以确定DCI中调度信息域的位置和/或长度。
如图5所示，本公开另一个实施例提供了一种传输调度方法，方法还包括：
步骤S510，根据调度信息域的配置信息，确定调度信息域在DCI中的位置和/或信息域长度。
在一个实施例中，配置信息可以指示调度信息域的起始位置和终止位置。例如，DCI占用12个比特位，配置信息指示调度信息域的起始位置为编号为第6的比特位，指示调度信息域的终止位置为编号为第9的比特位。这里，信息域占用4个比特位的长度。
在一个实施例中，配置信息可以指示调度信息域的起始位置和调度信息域的长度。例如，DCI占用12个比特位，配置信息指示调度信息域的起始位置的编号为第6的比特位，配置信息指示调度信息域的长度为占用4个比特位的长度。
在一个实施例中，可以是基于应用场景根据配置信息动态配置调度信息域在DCI中的位置和/或信息域长度。这样，使得调度信息域的配置更加 灵活，提升了DCI中各个比特位的利用率。例如，当调度在2个第二小区进行数据传输时，调度信息域只需要配置2个比特位；当调度在3个第二小区进行数据传输时，调度信息域则配置3个比特位。
在一个实施例中，UE支持调度在4个小区内进行数据传输，在一种应用场景中，如果设置一个DCI调度UE在2个小区内进行数据传输，则配置信息可以配置调度信息域在DCI中的信息域长度为2个比特位的长度。在另一种应用场景中，如果设置一个DCI调度UE在3个小区内进行数据传输，则配置信息可以配置调度信息域在DCI中的信息域长度为3个比特位的长度。
在一个实施例中，调度信息域包括：
比特位图，其中，比特位图中一个比特，用于指示是否调度一个第二小区进行数据传输。
在一个实施例中，比特位图包括4个比特位，第一个比特位用于指示小区1是否被调度；第二个比特位用于指示小区2是否被调度；第三个比特位用于指示小区3是否被调度；第四个比特位用于指示小区4是否被调度。当比特位取值为“0”时，对应小区没有被调度；当比特位取值为“1”时，对应小区被调度。请参见表一，示出了4个比特位的取值与小区是否被调度的关系。
比特位 比特位取值 小区调度情况
第1个比特位 0 小区1没有被调度
第1个比特位 1 小区1被调度
第2个比特位 0 小区2没有被调度
第2个比特位 1 小区2被调度
第3个比特位 0 小区3没有被调度
第3个比特位 1 小区3被调度
第4个比特位 0 小区4没有被调度
第4个比特位 1 小区4被调度
表一
在一个实施例中，请参见图6，比特位图的4个比特位的取值分别为“1”、“0”、“1”、“1”，则用于指示调度在小区1、小区3、小区4共3个小区内进行数据传输。其中，小区2没有被调度。
如图7所示，本公开另一个实施例提供了一种传输调度方法，方法还包括：
步骤S710，通过高层信令，下发比特位图与第二小区之间的映射关系的通知消息。
在一个实施例中，高层信令可以携带有比特位图与第二小区之间的映射关系的编码信息。例如，编码信息占用4个比特位。编码信息为“0001”时，用于指示：第1个比特位指示小区1；第2个比特位指示小区2；第3个比特位指示小区3；第4个比特位指示小区4；其中，小区1、小区2、小区3和小区4属于第二小区。这样，UE在接收到高层信令后就能够确定比特位图的各个比特位与第二小区之间的映射关系，并基于映射关系确定是否调度一个第二小区进行数据传输。
在一个实施例中，高层信息令可以是无线资源控制层(RRC，Radio Resource Control)的信令或媒体访问控制层(MAC,Media Access Control)的信令。例如，RRC信令、MAC控制元素(CE，Control Element)信令等。
在一个实施例中，调度信息域包括：
每个第二小区的指示信息。
在一个实施例中，指示信息可以是调度信息域携带的被调度的第二小区的标识信息。在一个实施例中，小区1的标识信息为“00”，小区2的标识信息为“01”，小区3的标识信息为“10”，小区4的标识信息为“11”，在小区 被调度时，调度信息域可以直接携带小区对应的标识信息。请参见图8，小区1的标识信息为“00”，小区3的标识信息为“10”，当小区1和小区3被调度时，调度信息域可以直接携带小区1的标识信息“00”和小区3的标识信息“10”。这里，指示信息可以指示终端在小区1和小区3内进行数据传输。
如图9所示，本公开另一个实施例提供了一种传输调度方法，方法还包括：
步骤S910，通过高层信令，下发指示信息与第二小区的映射关系的通知信息。
在一个实施例中，终端支持在4个第二小区上传输数据，并且一个下行控制信息DCI最多调度UE在2个第二小区内进行数据传输。UE可以基于指示信息与第二小区之间的映射关系获知调度哪些第二小区进行数据传输。这里，基站通过高层信令通知的方法，UE在收到高层信令后，就可以获知指示信息与第二小区的映射关系。
这里，UE在接收到高层信令后就能够确定指示信息与第二小区之间的映射关系，并基于映射关系确定调度对应的第二小区进行数据传输。
在一个实施例中，映射关系，包括：
第一类映射关系，其中，一个指示信息映射一个第二小区；
第二类映射关系，其中，一个指示信息映射一个或多个第二小区。
在一个实施例中，请参见表二，调度信息域的取值包含“00”时，指示信息指示小区1被调度；调度信息域的取值包含“01”时，指示信息指示小区2被调度；调度信息域的取值包含“10”时，指示信息指示小区3被调度；调度信息域的取值包含“11”时，指示信息指示小区4被调度；其中，小区1、小区2、小区3和小区4都为第二小区。
调度信息域包含的信息域值 指示信息
00 小区1被调度
01 小区2被调度
10 小区3被调度
11 小区4被调度
表二
在一个实施例中，请参见表三，当调度信息域的取值包含“000”时，指示信息指示小区1被调度；当调度信息域的取值包含“001”时，指示信息指示小区2被调度；当调度信息域的取值包含“010”时，指示信息指示小区3被调度；当调度信息域的取值包含“011”时，指示信息指示小区4被调度；当调度信息域的取值包含“100”时，指示信息指示小区1和小区2被调度；当调度信息域的取值包含“101”时，指示信息指示小区1和小区3被调度；当调度信息域的取值包含“110”时，指示信息指示小区1和小区4被调度；当调度信息域的取值包含“111”时，指示信息指示小区2和小区3被调度；其中，小区1、小区2、小区3和小区4为第二小区。
调度信息域包含的信息域值 指示信息
000 小区1被调度
001 小区2被调度
010 小区3被调度
011 小区4被调度
100 小区1和小区2被调度
101 小区1和小区3被调度
110 小区1和小区4被调度
111 小区2和小区3被调度
表三
在一个实施例中，每个第二小区在调度信息域中所占比特位的个数可以根据UE支持在多少个第二小区内进行传输数据或一个DCI最多调度UE 在多少个第二小区内进行数据传输的情况确定。
请参见图10，在一个实施例中，DCI中的调度信息域的取值包含“110”，则指示信息指示小区1和小区4被调度。
这里，采用多个小区联合编码的方式对调度信息域包含的信息进行编码，相比对每个小区进行单独编码的方式，可以大幅减少占用比特位的个数。例如，表三中示出的编码方式中，只需要占用3个比特位就可以表征8种不同的小区信息，如果采用对每个小区进行单独编码的方式，表征上述8种不同的小区信息至少需要占用4个比特位。
在一个实施例中，调度信息域包括：
分组信息，用于指示一个或多个小区组；其中，一个小区组包括一个或多个第二小区。
在一个实施例中，请参见表四，当调度信息域包含的信息域值为“00”时，分组信息指示调度在组号为1的小区组包含的小区1、小区2内进行数据传输；当调度信息域包含的信息域值为“01”时，分组信息指示调度在组号为2的小区组包含的小区3、小区4内进行数据传输；当调度信息域包含的信息域值为“10”时，分组信息指示调度在组号为3的小区组包含的小区1、小区4内进行数据传输；当调度信息域包含的信息域值为“11”时，分组信息指示调度在组号为4的小区组包含的小区2、小区3内进行数据传输；其中，小区1、小区2、小区3和小区4为第二小区。
调度信息域包含的信息域值 组号 分组信息
00 1 小区1，小区2
01 2 小区3，小区4
10 3 小区1，小区4
11 4 小区2，小区3
表四
这里，利用分组信息指示一个或多个小区组，可以大幅减少所述调度信息域占用比特位的位数。例如，可以是对小区组进行编号，然后针对小区组进行编码，获得分组信息。相比单独针对每个小区进行编码的方式，对小区组进行编码占用更少的比特位。在一个实施例中，单独编码的情况下，调度3个小区需要占用3个比特位，而采用本实施例的实现方式，只需要占用1个比特位，减少了比特开销。
在一个实施例中，基站可以预先将各小区组的分组信息发送给UE。在UE接收到某个小区组中的分组信息后，就可以确定所述分组信息对应的小区组中所包含的小区信息。
如图11所示，本公开另一个实施例提供了一种传输调度方法，方法还包括：
步骤S111，通过高层信令，下发分组信息与对应小区组所包含第二小区之间的映射关系的通知信息。
在一个实施例中，基站预先将第二小区进行分组，并通过高层信令，下发分组信息与对应小区组所包含第二小区之间的映射关系的通知信息。UE在接收到通知信息后，基于通知信息确定DCI中携带的分组信息，并调度在一个小区组包含的所有的第二小区内进行数据传输。
如图12所示，本公开另一个实施例提供了一种传输调度方法，该方法包括：
步骤S121，接收在第一小区内下发的一个调度在至少两个第二小区内进行数据传输的下行控制信息DCI；
在一个实施例中，基站在向UE下发下行控制信息(DCI，Downlink Control Information)时，首先，UE接收基站发送的下行控制信息DCI。下行控制信息DCI用于指示UE如下至少之一：如何接收基站发送的下行数据、如何向基站发送上行数据、如何调整发射功率；其次，UE在接收了下 行控制信息DCI之后，再根据DCI的指示进行数据传输。这里，数据传输可以是向基站发送上行数据，也可以是接收基站发送的下行数据。
在一个实施例中，每个小区都可以配置有一个载波。不同的小区采用不同的载波实现小区内无线信号的覆盖，完成小区内的数据传输。例如，A小区采用载波1实现小区内无线信号的覆盖；B小区采用载波2实现小区内无线信号的覆盖。
在一个实施例中，第二小区可以是与第一小区不同的小区。例如，第一小区为A小区，两个第二小区分别为B小区和C小区。在另一个实施例中，第二小区可以包括第一小区。例如，第一小区为A小区，两个第二小区分别为A小区和B小区。
本公开实施例中，通过在第一小区内下发一个所述DCI就可以实现调度在至少两个所述第二小区内进行数据传输，相比一个DCI只能调度在一个小区内进行数据传输的情况，可以有效地降低无线通信过程中控制信令的开销，提高无线资源的利用率。
步骤S122，根据DCI信息，在至少两个第二小区内进行数据传输。
这里，数据传输可以是接收基站发送的下行数据，也可以是向基站发送上行数据。
如图13所示，本公开另一个实施例提供了一种传输调度方法，步骤S122中，根据DCI信息，在至少两个第二小区内进行数据传输，包括：
步骤S131，根据DCI信息的调度信息域中包含的比特位图和比特位图与第二小区之间的映射关系，在比特位图中的比特指示的至少两个第二小区内进行数据传输；其中，比特位图中一个比特，用于指示是否调度一个第二小区进行数据传输。
在一个实施例中，比特位图包括4个比特位，第一个比特位用于指示小区1是否被调度；第二个比特位用于指示小区2是否被调度；第三个比 特位用于指示小区3是否被调度；第四个比特位用于指示小区4是否被调度。
在一个实施例中，请再次参见图6，比特位图的4个比特位的取值分别为1、0、1、1，则用于指示调度在小区1、小区3、小区4共3个小区内进行数据传输。
如图14所示，本公开另一个实施例提供了一种传输调度方法，步骤S131中，在在根据DCI信息的调度信息域中包含的比特位图和比特位图与第二小区之间的映射关系，在比特位图中的比特指示的至少两个第二小区内进行数据传输之前，还包括：
步骤S141，接收携带有比特位图与第二小区之间的映射关系的高层信令。
在一个实施例中，高层信令可以携带有比特位图与第二小区之间的映射关系的编码信息。例如，编码信息占用4个比特位。编码信息为“0001”时，用于指示：第1个比特位指示小区1；第2个比特位指示小区2；第3个比特位指示小区3；第4个比特位指示小区4；其中，小区1、小区2、小区3和小区4属于第二小区。这样，UE在接收到高层信令后就能够确定比特位图的各个比特位与第二小区之间的映射关系，并基于映射关系确定是否调度一个第二小区进行数据传输。
如图15所示，本公开另一个实施例提供了一种传输调度方法，步骤S122中，根据DCI信息，在至少两个第二小区内进行数据传输，包括：
步骤S151，根据DCI信息的信息域中包含的每个第二小区的指示信息和指示信息与第二小区的映射关系，在指示信息指示的至少两个第二小区内进行数据传输。
在一个实施例中，指示信息可以是调度信息域携带的被调度的第二小区的标识信息。在一个实施例中，小区1的标识信息为“00”，小区2的标识 信息为“01”，小区3的标识信息为“10”，小区4的标识信息为“11”，在小区被调度时，调度信息域可以直接携带小区对应的标识信息。请再次参见图8，小区1的标识信息为“00”，小区3的标识信息为“10”，当小区1和小区3被调度时，调度信息域可以直接携带小区1的标识信息“00”和小区3的标识信息“10”。这里，标识信息可以指示终端在小区1和小区3内进行数据传输。
如图16所示，本公开另一个实施例提供了一种传输调度方法，步骤S151中，在根据DCI信息的信息域中包含的每个第二小区的指示信息和指示信息与第二小区的映射关系，在指示信息指示的至少两个第二小区内进行数据传输之前，还包括：
步骤S161，接收携带有包含指示信息与第二小区的映射关系的高层信令。
在一个实施例中，终端支持在4个第二小区上传输数据，并且一个DCI最多调度UE在2个第二小区内进行数据传输。UE可以基于指示信息与第二小区之间的映射关系获知调度哪些第二小区进行数据传输。这里，基站通过高层信令通知的方法，UE在收到高层信令后，就可以获知指示信息与第二小区的映射关系。
在一个实施例中，高层信息令可以是无线资源控制层(RRC，Radio Resource Control)的信令或媒体访问控制层(MAC,Media Access Control)的信令。例如，RRC信令、MAC控制元素(CE，Control Element)信令等。
这里，UE在接收到高层信令后就能够确定指示信息与第二小区之间的映射关系，并基于映射关系确定调度对应的第二小区进行数据传输。
在一个实施例中，映射关系，包括：
第一类映射关系，其中，一个指示信息映射一个第二小区；
第二类映射关系，其中，一个指示信息映射一个或多个第二小区。
在一个实施例中，请再次参见表二，调度信息域的取值包含“00”时，指 示信息指示小区1被调度；调度信息域的取值包含“01”时，指示信息指示小区2被调度；调度信息域的取值包含“10”时，指示信息指示小区3被调度；调度信息域的取值包含“11”时，指示信息指示小区4被调度；其中，小区1、小区2、小区3和小区4都为第二小区。
在一个实施例中，请再次参见表三，当调度信息域的取值包含“000”时，指示信息指示小区1被调度；当调度信息域的取值包含“001”时，指示信息指示小区2被调度；当调度信息域的取值包含“010”时，指示信息指示小区3被调度；当调度信息域的取值包含“011”时，指示信息指示小区4被调度；当调度信息域的取值包含“100”时，指示信息指示小区1和小区2被调度；当调度信息域的取值包含“101”时，指示信息指示小区1和小区3被调度；当调度信息域的取值包含“110”时，指示信息指示小区1和小区4被调度；当调度信息域的取值包含“111”时，指示信息指示小区2和小区3被调度；其中，小区1、小区2、小区3和小区4为第二小区。
在一个实施例中，每个第二小区在调度信息域中所占比特位的个数可以根据UE支持在多少个第二小区内进行传输数据或一个DCI最多调度UE在多少个第二小区内进行数据传输的情况确定。
请再次参见图10，在一个实施例中，DCI中的调度信息域的取值包含“110”，则指示信息指示小区1和小区4被调度。
如图17所示，本公开另一个实施例提供了一种传输调度方法，步骤S122中，根据DCI信息，在至少两个第二小区内进行数据传输，包括：
步骤S171，根据DCI信息的信息域中包含的分组信息和分组信息与对应小区组所包含第二小区之间的映射关系，在小区组内包含的至少两个小区内进行数据传输。
在一个实施例中，请再次参见表四，当调度信息域包含的信息域值为“00”时，分组信息指示调度在组号为1的小区组包含的小区1、小区2内进 行数据传输；当调度信息域包含的信息域值为“01”时，分组信息指示调度在组号为2的小区组包含的小区3、小区4内进行数据传输；当调度信息域包含的信息域值为“10”时，分组信息指示调度在组号为3的小区组包含的小区1、小区4内进行数据传输；当调度信息域包含的信息域值为“11”时，分组信息指示调度在组号为4的小区组包含的小区2、小区3内进行数据传输；其中，小区1、小区2、小区3和小区4为第二小区。
如图18所示，本公开另一个实施例提供了一种传输调度方法，步骤S171中，在根据DCI信息的信息域中包含的分组信息和分组信息与对应小区组所包含第二小区之间的映射关系，在小区组内包含的至少两个小区内进行数据传输之前，还包括：
