Description

调度信息确定、下行控制信息发送方法和装置 技术领域
本公开涉及通信技术领域，具体而言，涉及调度信息确定方法、下行控制信息发送方法、调度信息确定装置、下行控制信息发送装置、通信装置和计算机可读存储介质。
背景技术
基于现有机制，当前小区的DCI(Downlink Control Information，下行控制信息)只允许调度一个小区的数据，例如调度PUSCH(Physical Uplink Shared Channel，物理上行共享信道)、PDSCH(Physical Downlink Shared Channel，物理下行共享信道)。
而随着通信技术的发展，频率资源的逐步碎片化，通过跨载波调度(Cross-Carrier Scheduling CCS)的方式利用这些分散的频谱资源，从而实现更高的网络吞吐量和良好的覆盖范围。而通过单个DCI调度分散的频谱资源对应的多小区数据，可以有效降低DCI的payload开销，提升系统容量。但是实现多个小区调度的单DCI的设计，目前并没有提出适当的解决方案。

图1A是根据本公开的实施例示出的一种调度信息确定方法的示意流程图。本实施例所示的调度信息确定方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述终端可以与网络设备通信，所述网络设备包括但不限于4G、5G、6G等通信系统中的网络设备，例如基站、核心网等。
如图1A所示，所述调度信息确定方法可以包括以下步骤：
在步骤S101中，接收网络设备发送的用于调度多个小区的下行控制信息DCI(Downlink Control Information)；
在步骤S102中，确定所述DCI中的相同类型的多个信息域与多个被调度小区之间的关联关系；
在步骤S103中，根据每个所述信息域的值和所述关联关系，确定每个所述被调度小区的调度信息。
在一个实施例中，DCI中可以包括多种类型的信息域，例如FDRA(Frequency Domain Resource Assignment，频域资源分配)域、ZP CSI-RS trigger(Zero Power Channel Information Reference Signal trigger，零功率信道状态信息参考信号触发)域、部分带宽指示(BandWidth Part indicator)域等。
对于现有机制的DCI，同一个类型的信息域，一般只包含一个，根据这个类型的信息域可以对一个小区进行调度，例如FDRA信息域可以调度目标小区的频域资源。
本实施例可以应用在一个DCI调度多个小区的场景中。在本实施例中，网络设备可以向终端发送DCI，用于调度多个小区(也即被调度小区)，其中一种可能的设计方式如下：对于DCI内的一种或多种类型的信息域，对于多个被调度小区，可以在DCI中设置相同类型的多个信息域，每个信息域可以针对其中一个小区进行调度。相同类型的信息域对应指示的信息类型相同，例如，指示不同小区的频域资源FDRA，例如，指示不同小区配置的BWP索引，具体可见下述描述。
这种指示方式可以称作分别separate方式，例如一个DCI中特定类型信息域可以包括多个信息域。可以在调度单个小区的一个DCI中信息域的基础上，根据被调度小区的数目对特定类型信息域做对应比特bits的扩展，从而得到多个相同类型的信息域，其中不同的信息域指示不同小区的消息。一个DCI中多个相同类型信息域所占的bits数等于每个被调度小区对应的上述信息域所占bits数的和。每个被调度小区对应的上述信息域所占bits数与现有机制中，调度一个小区的DCI的相同类型信息域所占bits数相同。
图1B是根据本公开的实施例示出的一种调度信息确定方法的应用场景示意图。如图1B所示，以BWP指示域为例，在用于调度3个小区(小区id号分别为0、1和2)的一个DCI中，包括3个BWP指示域(BWP指示域#1、BWP指示域#2、BWP指示域#3)，3个BWP指示域占用5bits，例如值为01100。
其中，第1个和第2个比特(01)可以作为BWP指示域#1对应小区0，那么可以根据第1个和第2个比特(01)确定小区0的BWP id＝2；第3个和第4个比特(10)可以作为BWP指示域#2对应小区1，那么可以根据第3个和第4个比特(10)确定小区1的BWP id＝3；第5个比特(0)可以作为BWP指示域#3对应小区0，那么可以根据第5个比特(0)确定小区2的BWP id＝1。
所述3个BWP指示域占用的bits数等于所述3个被调度小区BWP域所占bits数的和。对于特定被调度小区对应的BWP域所占bits数基于现有机制确定，即，基于特定被调度小区的高层配置BWP数量n BWP,RRC确定特定被调度小区对应的BWP域所占bits数。
对于调度多个小区的DCI中特定类型的信息域，若特定类型的信息域采用separate方式，特定类型的信息域可以包括多个信息域，多个信息域占用比特bits对应索引为：
Figure PCTCN2022090771-appb-000001
其中，索引1对应DCI特定类型信息域中的第一个bit，索引
Figure PCTCN2022090771-appb-000002
为第1个信息域对应bits，用于指示小区k 0的调度信息，索引
Figure PCTCN2022090771-appb-000003
为第j个信息域对应bits，用于指示小区k j的调度信息，索引
Figure PCTCN2022090771-appb-000004
为第n个信息域对应bits，用于指示小区k n的调度信息，n等于被调度小区数，其中k j为小区id号。例如预定义规则可以规定n个信息域中第j个信息域与n个被调度小区中的第j个被调度小区相关联，其中，第j个被调度小区的小区id可以为k j。
终端可以确定相同类型的多个信息域与多个被调度小区之间的关联关系，进而 根据关联关系确定每个信息域对应的被调度小区，从而可以根据被调度小区对应的信息域的值，确定被调度小区的调度信息。从而在通过一个DCI对多个小区进行调度的基础上，准确地确定每个小区的调度信息。
由于DCI中可以设置有多种类型的信息域，对于其中任意一种或几种类型，都可以采用separate的方式设置多个信息域来实现对多个小区的调度，具体针对哪种或哪几种类型设置多个信息域，可以根据预定义规则确定或根据信令指示确定。例如对于FDRA域和BWP指示域，信令指示FDRA域基于separate的方式指示，那么在DCI中可以针对多个被调度小区，设置多个FDRA域；例如预定义规则规定针对FDAR域和BWP域都基于separate的方式指示，那么在DCI中可以针对多个被调度小区，设置多个FDRA域以及多个BWP指示域。
需要说明的是，关于DCI所调度的多个小区的数量和/或多个小区对应的小区号，也即多个被调度小区，终端可以根据DCI中的CIF(Cell Indicator Field，小区指示域)来确定，也可以是与网络设备预先约定的，还可以是根据预定义规则(例如协议约定)确定的，本公开并不限制。
在一个实施例中，所述确定所述DCI中的相同类型的多个信息域与多个被调度小区之间的关联关系包括：根据预定义规则确定所述关联关系。
在一个实施例中，所述确定所述DCI中的相同类型的多个信息域与多个被调度小区之间的关联关系包括：根据网络设备的指示确定所述关联关系。
DCI中的相同类型的多个信息域与多个被调度小区之间的关联关系可以是预定义规则规定的，例如协议约定的；也可以是由网络设备指示的，其中，网络设备指示所述关联关系的方式包括但不限于通过RRC(Radio Resource Control，无线资源控制)信令进行指示、通过DCI进行指示、通过MAC CE(Media Access Control Control Element，媒体接入控制控制元素)进行指示。
以下实施例主要针对预定义规则规定所述关联关系的情况进行示例性说明。
在一个实施例中，所述多个信息域包括n个信息域，所述多个被调度小区包括n个被调度小区；所述预定义规则规定所述n个信息域中第j个信息域与所述n个被调度小区中的第j个被调度小区相关联，其中，1≤j≤n。
被调度小区可以包括终端接收所述DCI时所在小区以及其他小区(被调度小区中终端接收所述DCI时所在小区以外的小区)，也可以不包括终端接收所述DCI时所 在小区，仅包括其他小区。本实施中预定义规则在规定被调度小区与信息域之间的关联关系时，可以不区分终端接收所述DCI时所在小区以及其他小区，按照相同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系。
以n个被调度小区为例，针对某个类型的信息域，可以设置n个信息域来对这n个被调度小区进行调度，关联关系可以是n个信息域中第j个信息域与n个被调度小区中第j个被调度小区相关联。
据此，终端可以确定第j个信息域的值所指示的调度信息为第j个被调度小区的调度信息，从而在通过一个DCI对多个小区进行调度的基础上，准确地确定每个小区的调度信息。所述第j个信息域所占bits数以及具体指示方式与单个DCI调度单小区方式相同。
例如针对第1个小区至第n个被调度小区这n个被调度小区，以FDRA域采用separate指示方式为例，在DCI中可以设置n个FDRA域，预定义规则可以规定n个信息域中第j个信息域与n个被调度小区中的第j个被调度小区相关联，其中，第j个被调度小区的小区id可以为k j。在本实施例中，终端可以确定第1个FDRA域指示第1个被调度小区(小区k 1)的频域调度信息、第2个FDRA域指示第2个被调度小区(小区k 2)的频域调度信息、…、第j个FDRA域指示第j个被调度小区(小区k j)的频域调度信息、…、第n个FDRA域指示第n个被调度小区(小区k n)的频域调度信息，从而在通过一个DCI对多个小区进行调度的基础上，使得终端可以准确地解读DCI指示的每个小区的频域调度信息。
所述第j个FDRA域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第j个被调度小区的高层配置信令指示的资源分配类型(‘type 0’,‘type 1’,‘dynamic’)确定所述第j个FDRA域所占bits以及FDRA域指示的value与频域资源的对应关系。
例如针对第1个小区至第n个被调度小区这n个被调度小区，以ZP CSI-RS trigger域采用separate指示方式为例，在DCI中可以设置n个ZP CSI-RS trigger域，预定义规则可以规定n个信息域中第j个信息域与n个被调度小区中的第j个被调度小区相关联，其中，第j个被调度小区的小区id可以为k j。在本实施例中，终端可以确定第1个ZP CSI-RS trigger域指示第1个被调度小区(小区k 1)的ZP CSI-RS trigger信息、第2个ZP CSI-RS trigger域指示第2个被调度小区(小区k 2)的ZP CSI-RS trigger 信息、…、第j个ZP CSI-RS trigger域指示第j个被调度小区(小区k j)的ZP CSI-RS trigger信息、…、第n个ZP CSI-RS trigger域指示第n个被调度小区(小区k n)的ZP CSI-RS trigger信息，从而在通过一个DCI对多个小区进行调度的基础上，使得终端可以准确地解读DCI指示的每个小区的ZP CSI-RS trigger信息。
所述第j个ZP CSI-RS trigger域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第j个被调度小区的高层配置ZP CSI-RS资源集数量n ZP确定第j个ZP CSI-RS trigger域所占bits数。
例如针对第1个小区至第n个被调度小区这n个被调度小区，以BWP指示域采用separate指示方式为例，在DCI中可以设置n个BWP指示域，预定义规则可以规定n个信息域中第j个信息域与n个被调度小区中的第j个被调度小区相关联，其中，第j个被调度小区的小区id可以为k j。在本实施例中，终端可以确定第1个BWP指示域指示第1个被调度小区(小区k 1)的BWP信息、第2个BWP指示域指示第2个被调度小区(小区k 2)的BWP信息、…、第j个BWP指示域指示第j个被调度小区(小区k j)的BWP信息、…、第n个BWP指示域指示第n个被调度小区(小区k n)的BWP信息，从而在通过一个DCI对多个小区进行调度的基础上，使得终端可以准确地解读DCI指示的每个小区的BWP信息。
所述第j个BWP域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第j个被调度小区的高层配置BWP数量n BWP,RRC确定第j个BWP域所占bits数。
其中，关于多个信息域的顺序，可以按照多个信息域占用比特bit的顺序从前到后以此确定，也即第j个信息域占用的比特在第j+1个信息域占用的比特之前。而关于多个被调度小区的顺序，在后续实施例中说明如何确定。
需要说明的是，对于相同类型的多个信息域，每个信息域对应比特的数量可以相同，也可以不同，还可以为0，具体可以根据通信协议38.212[2]中的机制确定，本公开在此不作赘述。
以相同类型的4个信息域占用8个比特为例，若信息域对应比特的数量存在不同，那么可以是第1个信息域对应第1和第2个比特(即比特索引
Figure PCTCN2022090771-appb-000005
对应2个比特)，第2个信息域对应第3至第5个比特(即比特索引
Figure PCTCN2022090771-appb-000006
对应3个比特)，第3个信息域对应第6和第7个比特(即比特索引

对应2个比特)，第4 个信息域对应第8个比特(即比特索引
Figure PCTCN2022090771-appb-000008
对应1个比特)；若信息域对应比特的数量相同，那么可以是第1个信息域对应第1和第2个比特，第2个信息域对应第3和第4个比特，第3个信息域对应第5和第6个比特，第4个信息域对应第7和第8个比特，也即每个信息域对应2个比特(即比特索引
Figure PCTCN2022090771-appb-000009
对应2个比特)。
以下通过几个实施例示例性说明，预定义规则按照相同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系，以及如何确定多个被调度小区的顺序。
在一个实施例中，所述预定义规则规定第j个被调度小区的标识小于第j+1个被调度小区的标识，也即k j小于k j+1；或者，所述预定义规则规定第j个被调度小区的标识大于第j+1个被调度小区的标识，也即k j大于k j+1。
关于被调度小区的标识(例如Cell ID)，终端可以根据网络设备发送的RRC信令确定，例如根据RRC信令中的ServcellIndex和/或SCellIndex等信息元素(Information Element，IE)确定；而若小区的标识对应PCI(Physical Cell Identity，物理小区标识)，那么可以根据RRC信令中的信息元素PhysCellId确定；当然，也可以根据其他信令确定。或者，根据其他方式确定，例如可以为预定义规则规定的。
预定义规则可以根据被调度小区的标识对被调度小区进行排序，例如可以按照标识由小到大进行排序，那么第j个被调度小区的标识小于第j+1个被调度小区的标识，或者可以按照标识由大到小进行排序，那么第j个被调度小区的标识大于第j+1个被调度小区的标识。
例如以4个被调度小区为例，分别为标识为1的小区#1、标识为2的小区#2、标识为3的小区#3和标识为4的小区#4。若按照标识由小到大排序，那么k j小于k j+1，可以确定第1个小区为小区#1，第2个被调度小区为小区#2，第3个小区为小区#3，第4个小区为小区#4；若按照标识由大到小排序，那么k j大于k j+1，可以确定第1个小区为小区#4，第2个被调度小区为小区#3，第3个小区为小区#2，第4个小区为小区#1。
据此，可以根据小区的标识准确地确定小区的排序，进而可以第j个信息域调度的第j个被调度小区具体为哪个小区。
在一个实施例中，所述预定义规则规定第j个被调度小区的中心频率小于第j+1 个被调度小区的中心频率；或者，所述预定义规则规定第j个被调度小区的中心频率大于第j+1个被调度小区的中心频率。
关于被调度小区的中心频率，终端可以根据网络设备发送的信息确定，例如根据网络设备发送的同步信号块SSB(Synchronization Signal Block)确定；当然，也可以根据其他方式确定，例如可以为预定义规则规定的。
预定义规则可以根据被调度小区的中心频率对被调度小区进行排序，例如可以按照中心频率由小到大进行排序，那么第j个被调度小区的中心频率小于第j+1个被调度小区的中心频率，或者可以按照中心频率由大到小进行排序，那么第j个被调度小区的中心频率大于第j+1个被调度小区的中心频率。
例如以4个被调度小区为例，小区#1的中心频率为f1、小区#2的中心频率为f2、小区#3的中心频率为f3、小区#4的中心频率为f4，其中，f1＞f2＞f3＞f4。若按照中心频率由小到大排序，那么第1个小区为小区#4，第2个被调度小区为小区#3，第3个小区为小区#2，第4个小区为小区#1；若按照中心频率由大到小排序，那么第1个小区为小区#1，第2个被调度小区为小区#2，第3个小区为小区#3，第4个小区为小区#4。
据此，可以根据小区的中心频率准确地确定小区的排序，进而可以第j个信息域调度的第j个被调度小区具体为哪个小区。
在一个实施例中，所述预定义规则规定第j个被调度小区的中心频率对应的ARFCN(Absolute Radio Frequency Channel Number，绝对无线频率信道编号，具体可以是NR-ARFCN)小于第j+1个被调度小区的中心频率对应的ARFCN；或者，所述预定义规则规定第j个被调度小区的中心频率对应的ARFCN大于第j+1个被调度小区的中心频率对应的ARFCN。
关于被调度小区的ARFCN，终端可以根据被调度小区的中心频率确定，也可以通过其他方式确定。
预定义规则可以根据被调度小区的ARFCN对被调度小区进行排序，例如可以按照ARFCN由小到大进行排序，那么第j个被调度小区的ARFCN小于第j+1个被调度小区的ARFCN，或者可以按照ARFCN由大到小进行排序，那么第j个被调度小区的ARFCN大于第j+1个被调度小区的ARFCN。
例如以4个被调度小区为例，小区#1的ARFCN为ARFCN#1、小区#2的ARFCN 为ARFCN#2、小区#3的ARFCN为ARFCN#3、小区#4的ARFCN为ARFCN#4，其中，ARFCN#1＞ARFCN#2＞ARFCN#3＞ARFCN#4。若按照ARFCN由小到大排序，那么第1个小区为小区#4，第2个被调度小区为小区#3，第3个小区为小区#2，第4个小区为小区#1；若按照ARFCN由大到小排序，那么第1个小区为小区#1，第2个被调度小区为小区#2，第3个小区为小区#3，第4个小区为小区#4。
据此，可以根据小区的ARFCN准确地确定小区的排序，进而可以第j个信息域调度的第j个被调度小区具体为哪个小区。
在一个实施例中，所述多个信息域包括n个信息域，所述多个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区；所述预定义规则规定所述n个信息域中的第1个信息域与终端接收所述DCI时所在小区相关联，第2个信息域至第n个信息域中第i个信息域与所述n-1个其他小区中的第i-1个其他小区相关联，其中，2≤i≤n。
被调度小区可以包括终端接收所述DCI时所在小区以及其他小区(被调度小区中终端接收所述DCI时所在小区以外的小区)，也可以不包括终端接收所述DCI时所在小区，仅包括其他小区。本实施中预定义规则在规定被调度小区与信息域之间的关联关系时，可以区分终端接收所述DCI时所在小区以及其他小区，按照不同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系。
以n个被调度小区为例，若所述n个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区。针对某个类型的信息域，可以设置n个信息域来对这n个被调度小区进行调度，关联关系可以为n个信息域中的第1个信息域与终端接收所述DCI时所在小区相关联，第2个信息域至第n个信息域中第i个信息域与所述n-1个其他小区中的第i-1个其他小区相关联。也即对于n-1个其他小区，按照相同规则规定小区与信息域之间的关联关系，而对于终端接收所述DCI时所在小区，则规定与第1个信息域相关联。
据此，终端可以确定第1个信息域的值所指示的调度信息为终端接收所述DCI时所在小区的调度信息，从第2个信息域开始到第n个信息域为止，第i个信息域的值所指示的调度信息为第i-1个其他小区的调度信息，从而在通过一个DCI对多个小区进行调度的基础上，准确地确定每个小区的调度信息。所述第i个信息域所占bits数以及具体指示方式与单个DCI调度单小区方式相同。
例如针对第1个小区至第n个被调度小区这n个被调度小区，若所述n个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区，以FDRA域采用separate指示方式为例，在DCI中可以设置n个FDRA域，预定义规则可以规定n个FDRA域中第1个FDRA域与终端接收所述DCI时所在小区相关联，在第2个FDRA域到的第n个FDRA域的n-1个FDRA域中，第i个信息域与第i-1个其他小区相关联。若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，那么第i-1个被调度小区的小区id可以为k i-1。
在本实施例中，终端可以确定第1个FDRA域指示终端接收所述DCI时所在小区的频域调度信息，在第2个FDRA域到的第n个FDRA域的n-1个FDRA域中，第2个FDRA域指示第1个其他小区(小区k 1)的频域调度信息、…、第i个FDRA域指示第i-1个其他小区(小区k i-1)的频域调度信息、…、第n个FDRA域指示第n-1个其他小区(小区k n-1)的频域调度信息，从而在通过一个DCI对多个小区进行调度的基础上，使得终端可以准确地解读DCI指示的每个小区的频域调度信息。
所述第i个FDRA域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第i个被调度小区的高层配置信令指示的资源分配类型(‘type 0’,‘type 1’,‘dynamic’)确定所述第i个FDRA域所占bits以及FDRA域指示的value与频域资源的对应关系。
例如针对第1个小区至第n个被调度小区这n个被调度小区，若所述n个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区，以ZP CSI-RS trigger域采用separate指示方式为例，在DCI中可以设置n个ZP CSI-RS trigger域，预定义规则可以规定n个ZP CSI-RS trigger域中第1个ZP CSI-RS trigger域与终端接收所述DCI时所在小区相关联，在第2个ZP CSI-RS trigger域到的第n个ZP CSI-RS trigger域的n-1个FDRA域中，第i个信息域与第i-1个其他小区相关联。若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，那么第i-1个被调度小区的小区id可以为k i-1。
在本实施例中，终端可以确定第1个ZP CSI-RS trigger域指示终端接收所述DCI时所在小区的ZP CSI-RS trigger信息，在第2个ZP CSI-RS trigger域到的第n个BWP指示域的n-1个ZP CSI-RS trigger域中，第2个ZP CSI-RS trigger域指示第1个其他小区(小区k 1)的ZP CSI-RS trigger信息、…、第i个ZP CSI-RS trigger域指示 第i-1个其他小区(小区k i-1)的ZP CSI-RS trigger信息、…、第n个ZP CSI-RS trigger域指示第n-1个其他小区(小区k n-1)的ZP CSI-RS trigger信息，从而在通过一个DCI对多个小区进行调度的基础上，使得终端可以准确地解读DCI指示的每个小区的ZP CSI-RS trigger信息。
所述第i个ZP CSI-RS trigger域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第i个被调度小区的高层配置ZP CSI-RS资源集数量n ZP确定第i个ZP CSI-RS trigger域所占bits数。
例如针对第1个小区至第n个被调度小区这n个被调度小区，若所述n个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区，以BWP指示域采用separate指示方式为例，在DCI中可以设置n个BWP指示域，预定义规则可以规定n个BWP指示域中第1个BWP指示域与终端接收所述DCI时所在小区相关联，在第2个BWP指示域到的第n个BWP指示域的n-1个FDRA域中，第i个信息域与第i-1个其他小区相关联。若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，那么第i-1个被调度小区的小区id可以为k i-1。
在本实施例中，终端可以确定第1个BWP指示域指示终端接收所述DCI时所在小区的BWP信息，在第2个BWP指示域到的第n个BWP指示域的n-1个BWP指示域中，第2个BWP指示域指示第1个其他小区(小区k 1)的BWP信息、…、第i个BWP指示域指示第i-1个其他小区(小区k i-1)的BWP信息、…、第n个BWP指示域指示第n-1个其他小区(小区k n-1)的BWP信息，从而在通过一个DCI对多个小区进行调度的基础上，使得终端可以准确地解读DCI指示的每个小区的BWP信息。
所述第i个BWP域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第i个被调度小区的高层配置BWP数量n BWP,RRC确定第i个BWP域所占bits数。
其中，关于多个信息域的顺序，可以按照多个信息域占用比特bit的顺序从前到后以此确定，也即第i-1个信息域占用的比特在第i个信息域占用的比特之前。而关于多个被调度小区的顺序，在后续实施例中说明如何确定。
以下通过几个实施例示例性说明，预定义规则按照不同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系，如何确定多个被调度小区的顺序。
在一个实施例中，所述预定义规则规定第i-1个其他小区的标识小于第i个其他小区的标识；或者，所述预定义规则规定第i-1个其他小区的标识大于第i个其他小区的标识。
关于被调度小区的标识(例如Cell ID)，终端可以根据网络设备发送的RRC信令确定，例如根据RRC信令中的ServcellIndex和/或SCellIndex等IE确定；而在小区的标识对应PCI，那么可以根据RRC信令中的信息元素PhysCellId确定；当然，也可以根据其他方式确定，例如可以为预定义规则规定的。
预定义规则可以根据被调度小区的标识对被调度小区进行排序，例如可以按照标识由小到大进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的标识小于第i个其他小区的标识，若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，k i-1小于k i；或者可以按照标识由大到小进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的标识大于第i个其他小区的标识，若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，k i-1大于k i。
例如以4个被调度小区为例，分别为标识为1的小区#1、标识为2的小区#2、标识为3的小区#3和标识为4的小区#4，其中小区#3为终端接收所述DCI时所在小区。若按照标识由小到大排序，那么第1个小区为小区#3，对于除了小区#3以外的其他小区，k i-1小于k i，第2个被调度小区为小区#1，第3个小区为小区#2，第4个小区为小区#4；若按照标识由大到小排序，那么第1个小区为小区#3，对于除了小区#3以外的其他小区，k i-1大于k i，第2个被调度小区为小区#4，第3个小区为小区#2，第4个小区为小区#1。
据此，可以根据小区的标识准确地确定小区的排序，进而可以第i个信息域调度的第i个被调度小区具体为哪个小区。
在一个实施例中，所述预定义规则规定第i-1个其他小区的中心频率小于第i个其他小区的中心频率；或者，所述预定义规则规定第i-1个其他小区的中心频率大于第i个其他小区的中心频率。
关于被调度小区的中心频率，终端可以根据网络设备发送的信息确定，例如根据网络设备发送的同步信号块SSB确定；当然，也可以根据其他方式确定，例如可以为预定义规则规定的。
预定义规则可以根据被调度小区的中心频率对被调度小区进行排序，例如可以 按照中心频率由小到大进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的中心频率小于第i个其他小区的中心频率；或者可以按照中心频率由大到小进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的中心频率大于第i个其他小区的中心频率。
例如以4个被调度小区为例，小区#1的中心频率为f1、小区#2的中心频率为f2、小区#3的中心频率为f3、小区#4的中心频率为f4，其中，f1＞f2＞f3＞f4，小区#3为终端接收所述DCI时所在小区。若按照中心频率由小到大排序，那么第1个小区为小区#3，第2个被调度小区为小区#4，第3个小区为小区#2，第4个小区为小区#1；若按照中心频率由大到小排序，那么第1个小区为小区#3，第2个被调度小区为小区#1，第3个小区为小区#2，第4个小区为小区#4。
据此，可以根据小区的中心频率准确地确定小区的排序，进而可以第i个信息域调度的第i个被调度小区具体为哪个小区。
在一个实施例中，所述预定义规则规定第i-1个其他小区的中心频率对应的绝对无线频率信道编号ARFCN小于第i个其他小区的中心频率对应的ARFCN；或者，所述预定义规则规定第i-1个其他小区的中心频率对应的ARFCN大于第i个其他小区的中心频率对应的ARFCN。
关于被调度小区的ARFCN，终端可以根据被调度小区的中心频率确定，也可以通过其他方式确定。
预定义规则可以根据被调度小区的ARFCN对被调度小区进行排序，例如可以按照ARFCN由小到大进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的ARFCN小于第i个其他小区的ARFCN；或者可以按照ARFCN由大到小进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的ARFCN大于第i个其他小区的ARFCN。
例如以4个被调度小区为例，小区#1的ARFCN为ARFCN#1、小区#2的ARFCN为ARFCN#2、小区#3的ARFCN为ARFCN#3、小区#4的ARFCN为ARFCN#4，其中，ARFCN#1＞ARFCN#2＞ARFCN#3＞ARFCN#4，小区#3为终端接收所述DCI时所在小区。若按照ARFCN由小到大排序，那么第1个小区为小区#3，第2个被调度小区为小区#4，第3个小区为小区#2，第4个小区为小区#1；若按照ARFCN由大到小排序，那么第1个小区为小区#3，第2个被调度小区为小区#1，第3个小区为小区 #2，第4个小区为小区#4。
据此，可以根据小区的ARFCN准确地确定小区的排序，进而可以第i个信息域调度的第i个被调度小区具体为哪个小区。
图2是根据本公开的实施例示出的一种下行控制信息发送方法的示意流程图。本实施例所示的下行控制信息发送方法可以适用于网络设备，所述网络设备可以与终端通信，所述网络设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图2所示，所述下行控制信息发送方法可以包括以下步骤：
在步骤S201中，确定用于调度多个小区的下行控制信息DCI中相同类型的多个信息域与多个被调度小区之间的关联关系；
在步骤S202中，根据所述关联关系生成DCI；
在步骤S203中，向终端发送生成的DCI。
在一个实施例中，DCI中可以包括多种类型的信息域，例如FDRA域、ZP CSI-RS trigger域、部分带宽指示域等。
在现有的DCI中，同一个类型的信息域，一般只包含一个，根据这个类型的信息域可以对一个小区进行调度，例如FDRA信息域可以调度小区的频域资源。
本实施例可以应用在一个DCI调度多个小区的场景中。在本实施例中，网络设备可以确定相同类型的多个信息域与多个被调度小区之间的关联关系，进而根据所述关联关系设置每个小区的信息域，从而生成DCI，并将DCI发送至终端，实现对多个小区的调度。相同类型的信息域对应指示的信息类型相同，例如，指示不同小区的频域资源FDRA，例如，指示不同小区配置的BWP索引，具体可见下述描述。
这种指示方式可以称作分别separate指示，例如一个DCI中特定类型信息域可以包括多个信息域。可以在调度单个小区的一个DCI中信息域的基础上，根据被调度小区的数目对特定类型信息域做对应比特bits的扩展，从而得到多个相同类型的信息域，其中不同的信息域指示不同小区的消息。一个DCI中多个相同类型信息域所占的bits数等于每个被调度小区对应的上述信息域所占bits数的和。每个被调度小区对应的上述信息域所占bits数与现有机制中，调度一个小区的DCI的相同类型信息域所占 bits数相同。
如图1B所示，以BWP指示域为例，在用于调度3个小区(小区id号分别为0、1和2)的一个DCI中，包括3个BWP指示域，3个BWP指示域占用5bits，例如值为01100。
其中，第1个和第2个比特(01)对应小区0，因此可以根据第1个和第2个比特(01)确定小区0的BWP id＝2；第3个和第4个比特(10)对应小区1，因此可以根据第3个和第4个比特(10)确定小区1的BWP id＝3；第5个比特(0)对应小区0，因此可以根据第5个比特(0)确定小区2的BWP id＝1。
所述3个BWP指示域占用的bits数等于所述3个被调度小区BWP域所占bits数的和。对于特定被调度小区对应的BWP域所占bits数基于现有机制确定，即，基于特定被调度小区的高层配置BWP数量n BWP,RRC确定特定被调度小区对应的BWP域所占bits数。
对于调度多个小区的DCI中特定类型的信息域，若特定类型的信息域采用separate方式，特定类型的信息域可以包括多个信息域，多个信息域占用比特bits对应索引为：
Figure PCTCN2022090771-appb-000010
其中，索引1对应DCI特定类型信息域中的第一个bit，索引
Figure PCTCN2022090771-appb-000011
为第1个信息域对应对应bits，用于指示小区k 0的调度信息，索引
Figure PCTCN2022090771-appb-000012
为第i个信息域对应bits，用于指示小区k i的调度信息，索引
Figure PCTCN2022090771-appb-000013
为第n个信息域对应bits，用于指示小区k n的调度信息，n等于被调度小区数，其中k j为小区id号。例如预定义规则可以规定n个信息域中第j个信息域与n个被调度小区中的第j个被调度小区相关联，其中，第j个被调度小区的小区id可以为k j。
相对应地，终端可以确定相同类型的多个信息域与多个被调度小区之间的关联关系，进而根据关联关系确定每个信息域对应的被调度小区，从而可以根据被调度小区对应的信息域的值，确定被调度小区的调度信息，最后可以通过调度信息对对应的被调度小区进行调度。从而在通过一个DCI对多个小区进行调度的基础上，准确地确定每个小区的调度信息。
由于DCI中可以设置有多种类型的信息域，对于其中任意一种或几种类型，都可以采用separate的方式设置多个信息域来实现对多个小区的调度，具体针对哪种或哪几种类型设置多个信息域，可以根据预定义规则确定或根据信令指示确定。例如对于FDRA域和BWP指示域，信令指示FDRA域基于separate的方式指示，那么在DCI 中可以针对多个被调度小区，设置多个FDRA域；例如预定义规则规定针对FDAR域和BWP域都基于separate的方式指示，那么在DCI中可以针对多个被调度小区，设置多个FDRA域以及多个BWP指示域。
需要说明的是，关于DCI所调度的多个小区的数量和/或多个小区对应的小区号，也即多个被调度小区，终端可以根据DCI中的CIF来确定，也可以是与网络设备预先约定的，还可以是根据预定义规则(例如协议约定)确定的，本公开并不限制。
在一个实施例中，所述确定用于调度多个小区的下行控制信息DCI中相同类型的多个信息域与多个被调度小区之间的关联关系包括：根据预定义规则确定所述关联关系。
在一个实施例中，所述确定用于调度多个小区的下行控制信息DCI中相同类型的多个信息域与多个被调度小区之间的关联关系包括：根据所述网络设备的实现确定所述关联关系；其中，所述方法还包括：向所述终端指示所述关联关系。
DCI中的相同类型的多个信息域与多个被调度小区之间的关联关系可以是预定义规则规定的，例如协议约定的；也可以由网络设备根据需要确定，然后指示给终端，其中，网络设备指示所述关联关系的方式包括但不限于通过RRC信令进行指示、通过DCI进行指示、通过MAC CE进行指示。
以下实施例主要针对预定义规则规定所述关联关系的情况进行示例性说明。
在一个实施例中，所述多个信息域包括n个信息域，所述多个被调度小区包括n个被调度小区；所述预定义规则规定所述n个信息域中第j个信息域与所述n个被调度小区中的第j个被调度小区相关联，其中，1≤j≤n。
被调度小区可以包括终端接收所述DCI时所在小区以及其他小区(被调度小区中终端接收所述DCI时所在小区以外的小区)，也可以不包括终端接收所述DCI时所在小区，仅包括其他小区。本实施中预定义规则在规定被调度小区与信息域之间的关联关系时，可以不区分终端接收所述DCI时所在小区以及其他小区，按照相同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系。
以n个被调度小区为例，针对某个类型的信息域，可以设置n个信息域来对这n个被调度小区进行调度，关联关系可以是n个信息域中第j个信息域与n个被调度小区中第j个被调度小区相关联。
据此，终端可以确定第j个信息域的值所指示的调度信息为第j个被调度小区 的调度信息，从而在通过一个DCI对多个小区进行调度的基础上，准确地确定每个小区的调度信息。所述第j个信息域所占bits数以及具体指示方式与单个DCI调度单小区方式相同。
例如针对第1个小区至第n个被调度小区这n个被调度小区，以FDRA域采用separate指示方式为例，在DCI中可以设置n个FDRA域，预定义规则可以规定n个信息域中第j个信息域与n个被调度小区中的第j个被调度小区相关联，其中，第j个被调度小区的小区id可以为k j。在本实施例中，终端可以确定第1个FDRA域指示第1个被调度小区(小区k 1)的频域调度信息、第2个FDRA域指示第2个被调度小区(小区k 2)的频域调度信息、…、第j个FDRA域指示第j个被调度小区(小区k j)的频域调度信息、…、第n个FDRA域指示第n个被调度小区(小区k n)的频域调度信息，从而在通过一个DCI对多个小区进行调度的基础上，使得网络设备可以准确地确定每个小区的频域调度信息，进而生成DCI实现对每个小区的调度。
所述第j个FDRA域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第j个被调度小区的高层配置信令指示的资源分配类型(‘type 0’,‘type 1’,‘dynamic’)确定所述第j个FDRA域所占bits以及FDRA域指示的value与频域资源的对应关系。
例如针对第1个小区至第n个被调度小区这n个被调度小区，以ZP CSI-RS trigger域采用separate指示方式为例，在DCI中可以设置n个ZP CSI-RS trigger域，预定义规则可以规定n个信息域中第j个信息域与n个被调度小区中的第j个被调度小区相关联，其中，第j个被调度小区的小区id可以为k j。在本实施例中，终端可以确定第1个ZP CSI-RS trigger域指示第1个被调度小区(小区k 1)的ZP CSI-RS trigger信息、第2个ZP CSI-RS trigger域指示第2个被调度小区(小区k 2)的ZP CSI-RS trigger信息、…、第j个ZP CSI-RS trigger域指示第j个被调度小区(小区k j)的ZP CSI-RS trigger信息、…、第n个ZP CSI-RS trigger域指示第n个被调度小区(小区k n)的ZP CSI-RS trigger信息，从而在通过一个DCI对多个小区进行调度的基础上，使得网络设备可以准确地确定每个小区的ZP CSI-RS trigger信息，进而生成DCI实现对每个小区的调度。
所述第j个ZP CSI-RS trigger域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第j个被调度小区的高层配置ZP CSI-RS资源集数量n ZP确定第j个ZP  CSI-RS trigger域所占bits数。
例如针对第1个小区至第n个被调度小区这n个被调度小区，以BWP指示域采用separate指示方式为例，在DCI中可以设置n个BWP指示域，预定义规则可以规定n个信息域中第j个信息域与n个被调度小区中的第j个被调度小区相关联，其中，第j个被调度小区的小区id可以为k j。在本实施例中，终端可以确定第1个BWP指示域指示第1个被调度小区(小区k 1)的BWP信息、第2个BWP指示域指示第2个被调度小区(小区k 2)的BWP信息、…、第j个BWP指示域指示第j个被调度小区(小区k j)的BWP信息、…、第n个BWP指示域指示第n个被调度小区(小区k n)的BWP信息，从而在通过一个DCI对多个小区进行调度的基础上，使得网络设备可以准确地确定每个小区的BWP信息，进而生成DCI实现对每个小区的调度。
所述第j个BWP域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第j个被调度小区的高层配置BWP数量n BWP,RRC确定第j个BWP域所占bits数。
其中，关于多个信息域的顺序，可以按照多个信息域占用比特bit的顺序从前到后以此确定，也即第j个信息域占用的比特在第j+1个信息域占用的比特之前。而关于多个被调度小区的顺序，在后续实施例中说明如何确定。
需要说明的是，对于相同类型的多个信息域，每个信息域对应比特的数量可以相同，也可以不同，还可以为0，具体可以根据通信协议38.212[2]中的机制确定，本公开在此不作赘述。
以相同类型的4个信息域占用8个比特，若信息域对应比特的数量存在不同，那么可以是第1个信息域对应第1和第2个比特(即比特索引
Figure PCTCN2022090771-appb-000014
对应2个比特)，第2个信息域对应第3至第5个比特(即比特索引
Figure PCTCN2022090771-appb-000015
对应3个比特)，第3个信息域对应第6和第7个比特(即比特索引

对应2个比特)，第4个信息域对应第8个比特(即比特索引
Figure PCTCN2022090771-appb-000017
对应1个比特)；若信息域对应比特的数量相同，那么可以是第1个信息域对应第1和第2个比特，第2个信息域对应第3和第4个比特，第3个信息域对应第5和第6个比特，第4个信息域对应第7和第8个比特，也即每个信息域对应2个比特(即比特索引
Figure PCTCN2022090771-appb-000018
对应2个比特)。
以下通过几个实施例示例性说明，预定义规则按照相同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系，以及如何确定多个被调度小 区的顺序。
在一个实施例中，所述预定义规则规定第j个被调度小区的标识小于第j+1个被调度小区的标识，也即k j小于k j+1；或者，所述预定义规则规定第j个被调度小区的标识大于第j+1个被调度小区的标识，也即k j大于k j+1。
关于被调度小区的标识(例如Cell ID)，网络设备可以通过RRC信令进行指示，例如通过RRC信令中的ServcellIndex和/或SCellIndex等IE指示；而若小区的标识对应PCI，那么可以通过RRC信令中的信息元素PhysCellId指示；当然，终端也可以根据其他信令确定。或者，根据其他方式确定，例如可以为预定义规则规定的。
预定义规则可以根据被调度小区的标识对被调度小区进行排序，例如可以按照标识由小到大进行排序，那么第j个被调度小区的标识小于第j+1个被调度小区的标识，或者可以按照标识由大到小进行排序，那么第j个被调度小区的标识大于第j+1个被调度小区的标识。
例如以4个被调度小区为例，分别为标识为1的小区#1、标识为2的小区#2、标识为3的小区#3和标识为4的小区#4。若按照标识由小到大排序，那么k j小于k j+1，可以确定第1个小区为小区#1，第2个被调度小区为小区#2，第3个小区为小区#3，第4个小区为小区#4；若按照标识由大到小排序，那么k j大于k j+1，可以确定第1个小区为小区#4，第2个被调度小区为小区#3，第3个小区为小区#2，第4个小区为小区#1。
据此，可以根据小区的标识准确地确定小区的排序，进而可以第j个信息域调度的第j个被调度小区具体为哪个小区。
在一个实施例中，所述预定义规则规定第j个被调度小区的中心频率小于第j+1个被调度小区的中心频率；或者，所述预定义规则规定第j个被调度小区的中心频率大于第j+1个被调度小区的中心频率。
关于被调度小区的中心频率，网络设备通过向终端发送SSB进行指示；当然，终端也可以根据其他方式确定，例如可以为预定义规则规定的。
预定义规则可以根据被调度小区的中心频率对被调度小区进行排序，例如可以按照中心频率由小到大进行排序，那么第j个被调度小区的中心频率小于第j+1个被调度小区的中心频率，或者可以按照中心频率由大到小进行排序，那么第j个被调度 小区的中心频率大于第j+1个被调度小区的中心频率。
例如以4个被调度小区为例，小区#1的中心频率为f1、小区#2的中心频率为f2、小区#3的中心频率为f3、小区#4的中心频率为f4，其中，f1＞f2＞f3＞f4。若按照中心频率由小到大排序，那么第1个小区为小区#4，第2个被调度小区为小区#3，第3个小区为小区#2，第4个小区为小区#1；若按照中心频率由大到小排序，那么第1个小区为小区#1，第2个被调度小区为小区#2，第3个小区为小区#3，第4个小区为小区#4。
据此，可以根据小区的中心频率准确地确定小区的排序，进而可以第j个信息域调度的第j个被调度小区具体为哪个小区。
在一个实施例中，所述预定义规则规定第j个被调度小区的中心频率对应的绝对无线频率信道编号ARFCN小于第j+1个被调度小区的中心频率对应的ARFCN；或者，所述预定义规则规定第j个被调度小区的中心频率对应的ARFCN大于第j+1个被调度小区的中心频率对应的ARFCN。
关于被调度小区的ARFCN，网络设备可以根据被调度小区的中心频率确定，也可以通过其他方式确定。
预定义规则可以根据被调度小区的ARFCN对被调度小区进行排序，例如可以按照ARFCN由小到大进行排序，那么第j个被调度小区的ARFCN小于第j+1个被调度小区的ARFCN，或者可以按照ARFCN由大到小进行排序，那么第j个被调度小区的ARFCN大于第j+1个被调度小区的ARFCN。
例如以4个被调度小区为例，小区#1的ARFCN为ARFCN#1、小区#2的ARFCN为ARFCN#2、小区#3的ARFCN为ARFCN#3、小区#4的ARFCN为ARFCN#4，其中，ARFCN#1＞ARFCN#2＞ARFCN#3＞ARFCN#4。若按照ARFCN由小到大排序，那么第1个小区为小区#4，第2个被调度小区为小区#3，第3个小区为小区#2，第4个小区为小区#1；若按照ARFCN由大到小排序，那么第1个小区为小区#1，第2个被调度小区为小区#2，第3个小区为小区#3，第4个小区为小区#4。
据此，可以根据小区的ARFCN准确地确定小区的排序，进而可以第j个信息域调度的第j个被调度小区具体为哪个小区。
在一个实施例中，所述多个信息域包括n个信息域，所述多个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区；所述预定义规则规定所述n个信 息域中的第1个信息域与终端接收所述DCI时所在小区相关联，第2个信息域至第n个信息域中第i个信息域与所述n-1个其他小区中的第i-1个其他小区相关联，其中，2≤i≤n。
被调度小区可以包括终端接收所述DCI时所在小区以及其他小区(被调度小区中终端接收所述DCI时所在小区以外的小区)，也可以不包括终端接收所述DCI时所在小区，仅包括其他小区。本实施中预定义规则在规定被调度小区与信息域之间的关联关系时，可以区分终端接收所述DCI时所在小区以及其他小区，按照不同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系。
以n个被调度小区为例，若所述n个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区。针对某个类型的信息域，可以设置n个信息域来对这n个被调度小区进行调度，关联关系可以为n个信息域中的第1个信息域与终端接收所述DCI时所在小区相关联，第2个信息域至第n个信息域中第i个信息域与所述n-1个其他小区中的第i-1个其他小区相关联。也即对于n-1个其他小区，按照相同规则规定小区与信息域之间的关联关系，而对于终端接收所述DCI时所在小区，则规定与第1个信息域相关联。
据此，网络设备可以确定第1个信息域的值所指示的调度信息为终端接收所述DCI时所在小区的调度信息，从第2个信息域开始到第n个信息域为止，第i个信息域的值所指示的调度信息为第i-1个其他小区的调度信息，从而在通过一个DCI对多个小区进行调度的基础上，准确地确定每个小区的调度信息。所述第i个信息域所占bits数以及具体指示方式与单个DCI调度单小区方式相同。
例如针对第1个小区至第n个被调度小区这n个被调度小区，若所述n个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区，以FDRA域采用separate指示方式为例，在DCI中可以设置n个FDRA域，预定义规则可以规定n个FDRA域中第1个FDRA域与终端接收所述DCI时所在小区，在第2个FDRA域到的第n个FDRA域的n-1个FDRA域中，第i个信息域与第i-1个其他小区相关联，若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，那么第i-1个被调度小区的小区id可以为k i-1。
在本实施例中，终端可以确定第1个FDRA域指示终端接收所述DCI时所在小区的频域调度信息，在第2个FDRA域到的第n个FDRA域的n-1个FDRA域中， 第2个FDRA域指示第1个其他小区(小区k 1)的频域调度信息、…、第i个FDRA域指示第i-1个其他小区(小区k i-1)的频域调度信息、…、第n个FDRA域指示第n-1个其他小区(小区k n-1)的频域调度信息，从而在通过一个DCI对多个小区进行调度的基础上，使得网络设备可以准解读DCI指示的每个FDRA域对应的小区。
所述第i个FDRA域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第i个被调度小区的高层配置信令指示的资源分配类型(‘type 0’,‘type 1’,‘dynamic’)确定所述第i个FDRA域所占bits以及FDRA域指示的value与频域资源的对应关系。
例如针对第1个小区至第n个被调度小区这n个被调度小区，若所述n个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区，以ZP CSI-RS trigger域采用separate指示方式为例，在DCI中可以设置n个ZP CSI-RS trigger域，预定义规则可以规定n个ZP CSI-RS trigger域中第1个ZP CSI-RS trigger域与终端接收所述DCI时所在小区，在第2个ZP CSI-RS trigger域到的第n个ZP CSI-RS trigger域的n-1个FDRA域中，第i个信息域与第i-1个其他小区相关联，若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，那么第i-1个被调度小区的小区id可以为k i-1。
在本实施例中，终端可以确定第1个ZP CSI-RS trigger域指示终端接收所述DCI时所在小区的ZP CSI-RS trigger信息，在第2个ZP CSI-RS trigger域到的第n个BWP指示域的n-1个ZP CSI-RS trigger域中，第2个ZP CSI-RS trigger域指示第1个其他小区(小区k 1)的ZP CSI-RS trigger信息、…、第i个ZP CSI-RS trigger域指示第i-1个其他小区(小区k i-1)的ZP CSI-RS trigger信息、…、第n个ZP CSI-RS trigger域指示第n-1个其他小区(小区k n-1)的ZP CSI-RS trigger信息，从而在通过一个DCI对多个小区进行调度的基础上，使得网络设备可以准确地解读DCI指示的每个ZP CSI-RS trigger域对应的小区。
所述第i个ZP CSI-RS trigger域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第i个被调度小区的高层配置ZP CSI-RS资源集数量n ZP确定第i个ZP CSI-RS trigger域所占bits数。
例如针对第1个小区至第n个被调度小区这n个被调度小区，若所述n个被调度小区包括终端接收所述DCI时所在小区以及n-1个其他小区，以BWP指示域采用separate指示方式为例，在DCI中可以设置n个BWP指示域，预定义规则可以规定n 个BWP指示域中第1个BWP指示域与终端接收所述DCI时所在小区，在第2个BWP指示域到的第n个BWP指示域的n-1个FDRA域中，第i个信息域与第i-1个其他小区相关联，若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，那么第i-1个被调度小区的小区id可以为k i-1。
在本实施例中，终端可以确定第1个BWP指示域指示终端接收所述DCI时所在小区的BWP信息，在第2个BWP指示域到的第n个BWP指示域的n-1个BWP指示域中，第2个BWP指示域指示第1个其他小区(小区k 1)的BWP信息、…、第i个BWP指示域指示第i-1个其他小区(小区k i-1)的BWP信息、…、第n个BWP指示域指示第n-1个其他小区(小区k n-1)的BWP信息，从而在通过一个DCI对多个小区进行调度的基础上，使得网络设备可以准确地每个BWP指示域对应的小区。
所述第i个BWP域所占bits数根据通信协议38.212[2]中的机制确定，即：基于第i个被调度小区的高层配置BWP数量n BWP,RRC确定第i个BWP域所占bits数。
其中，关于多个信息域的顺序，可以按照多个信息域占用比特bit的顺序从前到后以此确定，也即第i-1个信息域占用的比特在第i个信息域占用的比特之前。而关于多个被调度小区的顺序，在后续实施例中说明如何确定。
以下通过几个实施例示例性说明，预定义规则按照不同规则规定终端接收所述DCI时所在小区以及其他小区与信息域之间的关联关系，如何确定多个被调度小区的顺序。
在一个实施例中，所述预定义规则规定第i-1个其他小区的标识小于第i个其他小区的标识；或者，所述预定义规则规定第i-1个其他小区的标识大于第i个其他小区的标识。
关于被调度小区的标识(例如Cell ID)，网络设备可通过RRC信令进行指示，例如通过RRC信令中的ServcellIndex和/或SCellIndex等IE指示；而在小区的标识对应PCI，那么可以通过RRC信令中的信息元素PhysCellId指示；当然，终端也可以根据其他方式确定，例如可以为预定义规则规定的。
预定义规则可以根据被调度小区的标识对被调度小区进行排序，例如可以按照标识由小到大进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的标识小于第i个其他小区的标识，若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，k i-1小于k i；或者可以按照标识由大到小进行排序，那么终端接 收所述DCI时所在小区为第1个小区，第i-1个其他小区的标识大于第i个其他小区的标识，若终端接收所述DCI时所在小区的小区id不在k 1至k n-1之间，k i-1大于。
例如以4个被调度小区为例，分别为标识为1的小区#1、标识为2的小区#2、标识为3的小区#3和标识为4的小区#4，其中小区#3为终端接收所述DCI时所在小区。若按照标识由小到大排序，那么第1个小区为小区#3，对于除了小区#3以外的其他小区，k i-1小于k i，第2个被调度小区为小区#1，第3个小区为小区#2，第4个小区为小区#4；若按照标识由大到小排序，那么第1个小区为小区#3，对于除了小区#3以外的其他小区，k i-1大于k i，第2个被调度小区为小区#4，第3个小区为小区#2，第4个小区为小区#1。
据此，可以根据小区的标识准确地确定小区的排序，进而可以第i个信息域调度的第i个被调度小区具体为哪个小区。
在一个实施例中，所述预定义规则规定第i-1个其他小区的中心频率小于第i个其他小区的中心频率；或者，所述预定义规则规定第i-1个其他小区的中心频率大于第i个其他小区的中心频率。
关于被调度小区的中心频率，网络设备通过向终端发送SSB进行指示；当然，终端也可以根据其他方式确定，例如可以为预定义规则规定的。
预定义规则可以根据被调度小区的中心频率对被调度小区进行排序，例如可以按照中心频率由小到大进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的中心频率小于第i个其他小区的中心频率；或者可以按照中心频率由大到小进行排序，那么终端接收所述DCI时所在小区为第1个小区，第i-1个其他小区的中心频率大于第i个其他小区的中心频率。
例如以4个被调度小区为例，小区#1的中心频率为f1、小区#2的中心频率为f2、小区#3的中心频率为f3、小区#4的中心频率为f4，其中，f1＞f2＞f3＞f4，小区#3为终端接收所述DCI时所在小区。若按照中心频率由小到大排序，那么第1个小区为小区#3，第2个被调度小区为小区#4，第3个小区为小区#2，第4个小区为小区#1；若按照中心频率由大到小排序，那么第1个小区为小区#3，第2个被调度小区为小区#1，第3个小区为小区#2，第4个小区为小区#4。
据此，可以根据小区的中心频率准确地确定小区的排序，进而可以第i个信息域调度的第i个被调度小区具体为哪个小区。
在一个实施例中，所述预定义规则规定第i-1个其他小区的中心频率对应的绝对无线频率信道编号ARFCN小于第i个其他小区的中心频率对应的ARFCN；或者，所述预定义规则规定第i-1个其他小区的中心频率对应的ARFCN大于第i个其他小区的中心频率对应的ARFCN。
