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。
发明内容
有鉴于此，本公开的实施例提出了调度信息确定方法、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，以解决相关技术中的技术问题。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以 被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
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；
在步骤S102中，确定所述DCI中的特定信息域的值value与多个调度信息之间的第一关联关系，以及所述多个调度信息与多个被调度小区之间的第二关联关系；
在步骤S103中，根据所述第一关联关系和所述第二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，一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)，具体可以将DCI中的特定信息域的值(某一个信息域的值，而非多个信息域的值)与多个调度信息建立关联关系(也即一个信息域的值关联多个调度信息)，例如称作第一关联关系，以及将多个调度信息与多个被调度小区之间建立关联关系，例如称作第二关联关系。一种类型的信息域的值对应的多个调度信息类型是相同的，例如，对应不同小区的频域资源FDRA，例如，对应不同小区配置的BWP索引，具体可见下述描述。
这种指示方式可以称作联合combined或共享shared指示，例如对于一个DCI中特定类型信息域指示的特定值，可以关联多个调度信息，多个调度信息则与多个被调度小区相关联。
所述第一关联关系可以通过预定义方式确定，也可以通过信令指示的方式确定。以信令指示的方式为例，网络侧可以基于信令指示(例如无线资源控制RRC信令)定义DCI特定类型信息域指示的特定值与多个调度信息的第一关联关系。所述信令可以为接收DCI所在小区配置的信令。以RRC信令为例，终端在接收DCI所在小区接收对应的RRC信令，所述RRC信令指示DCI特定类型信息域指示的特定值与多个调度信息的关联关系。其中，特定类型信息域所占的bits数与RRC信令配置的指示值的范围有关。
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，对应DCI在小区0接收。
例如所述第一关联关系通过信令指示的方式确定，终端在小区0接收对应RRC信令，以确定用于调度多个小区的DCI中BWP指示域的值与多个小区配置BWP id之间的第一关联关系。例如对于BWP指示域，第一关联关系可以如下表1所示：

如表1所示，BWP指示域所占bits数为log 2(4)＝2,在BWP指示域的值为01的场景下，根据第一关联关系可以确定BWP指示域的值01关联3个调度信息，第1个调度信息为BWP id＝2，第2个调度信息为BWP id＝3，第3个调度信息为BWP id＝1。 进而根据第二关联关系可以确定第1个调度信息与小区0相关联，第2个调度信息与小区1相关联，第3个调度信息与小区2相关联，那么可以确定小区0的BWP id＝2，小区1的BWP id＝3，小区2的BWP id＝1。

终端可以确定DCI中特定信息域的值与多个调度信息之间的第一关联关系，以及多个调度信息与多个被调度小区之间的第二关联关系，然后可以根据第一关联关系可以确定DCI中特定信息域的值对应的多个调度信息，以及根据第二关联关系确定每个调度信息对应的被调度小区，进而确定每个被调度小区的调度信息。从而在网络设备通过一个DCI对多个小区进行调度的基础上，终端可以准确地解读DCI指示的每个小区的调度信息。上文主要对第一关联关系的具体实现方式做了具体介绍，对应第二关联关系的确定关系将在下文展开。
需要说明的是，关于DCI所调度的多个小区，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中的特定信息域的值与多个调度信息之间的第一关联关系包括：根据网络设备的指示确定所述第一关联关系。例如网络设备可以确定DCI中信息域(某一个信息域，而非多个信息域)的值与多个调度信息之间的关联关系，然后通过RRC(Radio Resource Control，无线资源控制)信令指示给终端。当然，也可以根据预定义规则确定，例如基于协议约定确定。
在一个实施例中，所述确定所述多个调度信息与多个被调度小区之间的第二关联关系包括：根据预定义规则确定所述第二关联关系。
DCI中的特定信息域的值与多个调度信息之间的第一关联关系，以及多个调度信息与多个被调度小区之间的第二关联关系，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。所述DCI中的信息域所 占的bits数由基于信令指示或预定以方式确定的value的个数确定，示例性地，若第一关联关系定义了N个信息域的值，所述每个信息域的值与多个调度信息相关联，则DCI中的信息域所占的bits数等于log 2(N)。
以下实施例主要针对预定义规则规定所述第二关联关系的情况进行示例性说明。
在一个实施例中，所述多个调度信息包括n个调度信息，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个调度信息中第j个调度信息与所述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调度信息之间的关联关系时，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调度信息之间的关联关系。
以n个被调度小区为例，可以根据第一关联关系和DCI中信息域的值确定n个调度信息，并根据第二关联关系确定n个调度信息与n个被调度小区之间的对应关系，第二关联关系可以是n个调度信息中第j个调度信息与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个调度信息为第j个被调度小区的调度信息，从而在网络设备通过一个DCI对多个小区进行调度的基础上，终端可以准确地解读DCI指示的每个小区的调度信息。
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combine指示方式为例，根据FDRA域的值以及第一关联关系可以确定n个调度信息，例如

其中k j为小区id号。在本实施例中，终端可以根据第二关联关系确定第1个调度信息为第1个被调度小区(小区k 1)的频域调度信息、第2个调度信息为第2个被调度小区(小区k 2)的频域调度信息、…、第j个调度信息为第j个被调度小区(小区k j)的频域调度信息、…、第n个调度信息为第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。

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combine指示方式为例，根据BWP指示域的值以及第一关联关系可以确定n个调度信息，例如

Figure PCTCN2022090769-appb-000011
其中k j为小区id号。在本实施例中，终端可以根据第二关联关系确定第1个调度信息为第1个被调度小区(小区k 1)的BWP信息、第2个调度信息为第2个被调度小区(小区k 2)的BWP信息、…、第j个调度信息为第j个被调度小区(小区k j)的BWP信息、…、第n个BWP调度信息为第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。
其中，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，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，例如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，例如k j大于k j+1。
在一个实施中，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。
预定义规则可以规定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，进而可以确定第j个信息域具体为第j个被调度小区的调度信息。
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。
预定义规则可以规定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 域具体为第j个被调度小区的调度信息。
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，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。
预定义规则可以规定根据被调度小区的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个信息域具体为第j个被调度小区的调度信息。
在一个实施例中，所述多个调度信息包括n个调度信息，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其他个小区；所述预定义规则规定所述n个调度信息中的第1个调度信息与终端接收所述DCI时所在小区相关联，第2个调度信息至第n个调度信息中第i个调度信息所指示的信息与所述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调度信息之间的关联关系时，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调度信息之间的关联关系。
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。可以根据第一关联关系和DCI中调度信息的值确定n个调度信息，并根据第二关联关系确定n个调度信息与n个被调度小区之间的对应关系，第二关联关系可以是n个调度信息中的第1个调度信息与终端接收所述DCI时所在小区相关联，第2个调度信息至第n个调度信息中第i个调度信息与所述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调度信息之间的关联关系，而对于终端接收所述DCI时所在小区，则规定与第1个调度信息相关联。
据此，终端可以确定第1个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个调度信息开始到第n个调度信息为止，第i个调度信息为第i-1个其他小区的调度信息，从而在网络设备通过一个DCI对多个小区进行调度的基础上，终端可以准确地解读DCI指示的每个小区的调度信息。
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combine指示方式为例，根据FDRA域的值以及第一关联关系可以确定n个调度信息。预定义规则规定的第二关联关系可以为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，终端可以根据第二关联关系确定第1个调度信息为终端接收所述DCI时所在小区的频域调度信息，在第2个调度信息为到的第n个调度信息为的n-1个调度信息为中，第2个调度信息为第1个其他小区的频域调度信息、…、第i个调度信息为第i-1个其他小区的频域调度信息、…、第n个调度信息为第n-1个其他小区的频域调度信息，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。
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combine指示方式为例，根据ZP CSI-RS trigger域的值以及第一关联关系可以确定n个调度信息。预定义规则规定的第二关联关系可以为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，终端可以根据第二关联关系确定第1个调度信息为终端接收所述DCI时所在小区的ZP CSI-RS trigger信息，在第2个调度信息到第n个调度信息的n-1个调度信息中，第2个调度信息为第1个其他小区(小区k 1)的ZP CSI-RS trigger信息、…、第i个调度信息为第i-1个其他小区(小区k i-1)的ZP CSI-RS trigger信息、…、第n个调度信息为第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。
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combine指示方式为例，根据BWP指示域的值以及第一关联关系可以确定n个调度信息。预定义规则规定的第二关联关系可以为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，终端可以根据第二关联关系确定第1个调度信息为第1个小区的BWP信息，在第2个调度信息为到的第n个调度信息为的n-1个调度信息为中，第2个调度信息为第1个其他小区(小区k 1)的BWP信息、…、第i个调度信息为第i-1个其他小区(小区k i-1)的BWP信息、…、第n个调度信息为第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。
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个被调度小区的标识小于第i个被调度小区的标识；或者，所述预定义规则规定第i-1个被调度小区的标识大于第i个被调度小区的标识。
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。
预定义规则可以规定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个被调度小区为小区#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个被调度小区为小区#2，第4个被调度小区为小区#4；若按照标识由大到小排序，那么第1个被调度小区为小区#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个被调度小区为小区#2，第4个被调度小区为小区#1。
据此，可以根据小区的标识准确地确定小区的排序，进而可以确定第1个调度信息为终端接收所述DCI时所在小区的调度信息，第i个调度信息具体为第i个其他小区的调度信息。
在一个实施例中，所述预定义规则规定第i-1个被调度小区的中心频率小于第i个被调度小区的中心频率；或者，所述预定义规则规定第i-1个被调度小区的中心频率小于第i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。
预定义规则可以规定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个被调度小区为小区#3，第2个被调度小区为小区#4，第3个被调度小区为小区#2，第4个被调度小区为小区#1；若按照中心频率由大到小排序，那么第1个被调度小区为小区#3，第2个被调度小区为小区#1，第3个被调度小区为小区#2，第4个被调度小区为小区#4。
据此，可以根据小区的中心频率准确地确定小区的排序，进而可以确定第1个调度信息为终端接收所述DCI时所在小区的调度信息，第i个调度信息具体为第i个其他小区的调度信息。
在一个实施例中，所述预定义规则规定第i-1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i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i-1个被调度小区的中心频率对应的ARFCN大于第i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。
预定义规则可以规定根据被调度小区的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个被调度小区为小区#3，第2个被调度小区为小区#4，第3个被调度小区为小区#2，第4个被调度小区为小区#1；若按照ARFCN由大到小排序，那么第1个被调度小区为小区#3，第2个被调度小区为 小区#1，第3个被调度小区为小区#2，第4个被调度小区为小区#4。
据此，可以根据小区的ARFCN准确地确定小区的排序，进而可以确定第1个调度信息为终端接收所述DCI时所在小区的调度信息，第i个调度信息具体为第i个其他小区的调度信息。
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，确定所述DCI中的特定信息域的值与相同类型的多个调度信息之间的第一关联关系，以及所述多个调度信息与多个被调度小区之间的第二关联关系；
在步骤S202中，根据所述第一关联关系和第二关联关系生成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。
对于现有机制的DCI，一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)，具体可以将DCI中的特定信息域的值(某一个信息域的值，而非多个信息域的值)与多个调度信息建立关联关系(也即一个信息域的值关联多个调度信息)，例如称作第一关联关系，以及将多个调度信息与多个被调度小区之间建立关联关系，例如称作第二关联关系。一种类型的信息域的值对应的多个调度信息类型是相同的，例如，对应不同小区的频域资源FDRA，例如，对应不同小区配置的BWP索引，具体可见下述描述。
这种指示方式可以称作联合combined或共享shared指示，例如对于一个DCI中特定类型信息域指示的特定值，可以关联多个调度信息，多个调度信息则与多个被 调度小区相关联。
所述第一关联关系可以通过预定义方式确定，也可以通过信令指示的方式确定。以信令指示的方式为例，网络侧可以基于信令指示(例如无线资源控制RRC信令)定义DCI特定类型信息域指示的特定值与多个调度信息的第一关联关系。所述信令可以为接收DCI所在小区配置的信令。以RRC信令为例，终端在接收DCI所在小区接收对应的RRC信令，所述RRC信令指示DCI特定类型信息域指示的特定值与多个调度信息的关联关系。其中，特定类型信息域所占的bits数与RRC信令配置的指示值的范围有关。
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，对应DCI在小区0接收。
例如所述第一关联关系通过信令指示的方式确定，终端在小区0接收对应RRC信令，以确定用于调度多个小区的DCI中BWP指示域的值与多个小区配置BWP id之间的第一关联关系。例如对于BWP指示域，第一关联关系可以如前文表1所示。
如表1所示，BWP指示域所占bits数为log 2(4)＝2,在BWP指示域的值为01的场景下，根据第一关联关系可以确定BWP指示域的值为01。例如BWP指示域的值001可以关联3个调度信息，第1个调度信息为BWP id＝2，第2个调度信息为BWP id＝3，第3个调度信息为BWP id＝1，并且第1个调度信息与小区0相关联，第2个调度信息与小区1相关联，第3个调度信息与小区2相关联，那么可以确定小区0的BWP id＝2，小区1的BWP id＝3，小区2的BWP id＝1。
对于调度多个小区的DCI中特性类型的信息域，信息域的值可以关联调度信息

网络设备可以确定DCI中特定信息域的值与多个调度信息之间的第一关联关系，以及多个调度信息与多个被调度小区之间的第二关联关系，然后根据所述第一关联关系和第二关联关系生成DCI，并将生成的DCI发送至向终端。终端接收到网络设备发送的DCI后，可以根据第一关联关系可以确定DCI中特定信息域的值对应的多个调度信息，以及根据第二关联关系确定每个调度信息对应的被调度小区，进而确定每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，使得 终端可以准确地解读DCI指示的每个小区的调度信息。上文主要对第一关联关系的具体实现方式做了具体介绍，对应第二关联关系的确定关系将在下文展开。
需要说明的是，关于DCI所调度的多个小区，也即多个被调度小区，网络设备可以根据DCI中的CIF对终端进行指示确定，也可以是与终端预先约定的，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中的特定信息域的值与相同类型的多个调度信息之间的第一关联关系包括：根据所述网络设备的实现确定所述第一关联关系和/或所述第二关联关系；其中，所述方法还包括：向所述终端指示所述第一关联关系。例如网络设备可以确定DCI中特定信息域的值与多个调度信息之间的关联关系，然后通过RRC信令指示给终端。当然，也可以根据预定义规则确定，例如基于协议约定确定。
在一个实施例中，所述确定所述多个调度信息与多个被调度小区之间的第二关联关系包括：根据预定义规则确定所述第二关联关系。
DCI中的特定信息域的值与多个调度信息之间的第一关联关系，以及多个调度信息与多个被调度小区之间的第二关联关系，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信令进行指示、通过DCI进行指示、通过MAC CE进行指示。所述DCI中的信息域所占的bits数由基于信令指示或预定以方式确定的value的个数确定，示例性地，若第一关联关系定义了N个信息域的值，所述每个信息域的值与多个调度信息相关联，则DCI中的信息域所占的bits数等于log 2(N)。
以下实施例主要针对预定义规则规定所述第二关联关系的情况进行示例性说明。
在一个实施例中，所述多个调度信息包括n个调度信息，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个调度信息中第j个调度信息与所述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调度信息之间的关联关系时，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调度信息之间的关联关系。
以n个被调度小区为例，网络设备可以确定DCI中信息域的值与n个调度信息之间的第一关联关系，并将第一关联关系指示给终端。还可以根据第二关联关系确定n个调度信息与n个被调度小区之间的对应关系，第二关联关系可以是n个调度信息中第j个调度信息与n个被调度小区中第j个被调度小区相关联，进而根据第一关联关系和第二关联关系可以生成DCI，实现通过一个DCI对多个小区进行调度。
据此，网络设备可以通过DCI中信息域的值指示与n个被调度信息相关联的n个调度信息。终端可以确定第j个调度信息为第j个被调度小区的调度信息，从而在网络设备通过一个DCI对多个小区进行调度的基础上，终端可以准确地解读DCI指示的每个小区的调度信息。
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combine指示方式为例，网络设备可以确定根据FDRA域的值与n个调度信息(例如

其中k j为小区id号)之间的第一关联关系。在本实施例中，网络设备可以根据第二关联关系确定第1个调度信息为第1个被调度小区(小区k 1)的频域调度信息、第2个调度信息为第2个被调度小区(小区k 2)的频域调度信息、…、第j个调度信息为第j个被调度小区(小区k j)的频域调度信息、…、第n个调度信息为第n个被调度小区(小区k n)的频域调度信息，进而可以根据第一关联关系和第二关联关系生成DCI，实现通过一个DCI对多个小区进行调度，并且可以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。
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combine指示方式为例，网络设备可以确定根据ZP CSI-RS trigger域的值与n个调度信息(例如

其中k j为小区id号)之间的第一关联关系。在本实施例中，网络设备可以根据第二关联关系确定第1个调度信息为第1个被调度小区(小区k 1)的ZP CSI-RS trigger信息、第2个调度信息为第2个被调度小区(小区k 2)的ZP CSI-RS trigger信息、…、第j个调度信息为第j个被调度小区(小区k j)的ZP CSI-RS trigger信息、…、第n个调度信息为第n个被调度小区(小区k n)的ZP CSI-RS trigger信息，进而可以根据第一关联关系和第二关联关系生成DCI，实现通过一个DCI对多个小区进行调度，并且可以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。
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combine指示方式为例，网络设备可以确定根据BWP指示域的值与n个调度信息(例如

Figure PCTCN2022090769-appb-000021
其中k j为小区id号)之间的第一关联关系。在本实施例中，网络设备可以根据第二关联关系确定第1个调度信息为第1个被调度小区(小区k 1)的BWP信息、第2个调度信息为第2个被调度小区(小区k 2)的BWP信息、…、第j个调度信息为第j个被调度小区(小区k j)的BWP信息、…、第n个BWP调度信息(小区k n)为第n个被调度小区的BWP信息，进而可以根据第一关联关系和第二关联关系生成DCI，实现通过一个DCI对多个小区进行调度，并且可以使得终端可以准确地解读DCI指示的每个小区的BWP信息。
其中，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，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，例如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，例如k j大于k j+1。
在一个实施中，关于被调度小区的标识(例如Cell ID)，网络设备可以对终端进行指示，例如通过RRC信令指示，例如通过RRC信令中的ServcellIndex和/或SCellIndex等信息元素指示；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。
预定义规则可以规定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，进而可以确定第j个信息域具体为第j个被调度小区的调度信息。
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，网络设备可以发送信息对终端进行指示，例如发送同步信号块SSB(Synchronization Signal Block)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。
预定义规则可以规定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个信息域具体为第j个被调度小区的调度信息。
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，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。
预定义规则可以规定根据被调度小区的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个信息域具体为第j个被调度小区的调度信息。
在一个实施例中，所述多个调度信息包括n个调度信息，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其他个小区；所述预定义规则规定所述n个调度信息中的第1个调度信息与终端接收所述DCI时所在小区相关联，第2个调度信息至第n个调度信息中第i个调度信息所指示的信息与所述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调度信息之间的关联关系时，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调度信息之间的关联关系。
以n个被调度小区为例，网络设备可以确定DCI中信息域的值与n个调度信息之间的第一关联关系，并将第一关联关系指示给终端。还可以根据第二关联关系确定n个调度信息与n个被调度小区之间的对应关系，第二关联关系可以是n个调度信息中的第1个调度信息与终端接收所述DCI时所在小区相关联，第2个调度信息至第n个调度信息中第i个调度信息与所述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调度信息之间的关联关系，而对于终端接收所述DCI时所在小区，则规定与第1个调度信息相关联。
据此，网络设备可以通过DCI中信息域的值指示与n个被调度信息相关联的n个调度信息。终端可以确定第1个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个调度信息开始到第n个调度信息为止，第i个调度信息为第i-1个其他小区的调度信息，从而在网络设备通过一个DCI对多个小区进行调度的基础上，终端可以准确地解读DCI指示的每个小区的调度信息。
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combine指示方式为例，根据FDRA域的值以及第一关联关系可以确定n个调度信息。预定义规则规定的第二关联关系可以为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，网络设备可以根据第二关联关系确定第1个调度信息为终端接收所述DCI时所在小区的频域调度信息，在第2个调度信息为到的第n个调度信息为的n-1个调度信息为中，第2个调度信息为第1个其他小区的频域调度信息、…、第i个调度信息为第i-1个其他小区的频域调度信息、…、第n个调度信息为第n-1个其他小区的频域调度信息，进而可以根据第一关联关系和第二关联关系生成DCI，实现通过一个DCI对多个小区进行调度，并且可以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。
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combine指示方式为例，根据ZP CSI-RS trigger域的值以及第一关联关系可以确定n个调度信息。预定义规则规定的第二关联关系可以为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，网络设备可以根据第二关联关系确定第1个调度信息为终端接收所述DCI时所在小区的ZP CSI-RS trigger信息，在第2个调度信息到第n个调度信息的n-1个调度信息中，第2个调度信息为第1个其他小区(小区k 1)的ZP CSI-RS trigger信息、…、第i个调度信息为第i-1个其他小区(小区k i-1)的ZP CSI-RS trigger 信息、…、第n个调度信息为第n-1个其他小区(小区k n-1)的ZP CSI-RS trigger信息，进而可以根据第一关联关系和第二关联关系生成DCI，实现通过一个DCI对多个小区进行调度，并且可以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。
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combine指示方式为例，根据BWP指示域的值以及第一关联关系可以确定n个调度信息。预定义规则规定的第二关联关系可以为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，网络设备可以根据第二关联关系确定第1个调度信息为第1个小区的BWP信息，在第2个调度信息为到的第n个调度信息为的n-1个调度信息为中，第2个调度信息为第1个其他小区(小区k 1)的BWP信息、…、第i个调度信息为第i-1个其他小区(小区k i-1)的BWP信息、…、第n个调度信息为第n-1个其他小区(小区k n-1)的BWP信息，进而可以根据第一关联关系和第二关联关系生成DCI，实现通过一个DCI对多个小区进行调度，并且可以使得终端可以准确地解读DCI指示的每个小区的BWP信息。
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个被调度小区的标识小于第i个被调度小区的标识；或者，所述预定义规则规定第i-1个被调度小区的标识大于第i个被调度小区的标识。
在一个实施例中，关于被调度小区的标识(例如Cell ID)，网络设备可以对终端进行指示，例如通过RRC信令指示，例如通过RRC信令中的ServcellIndex和/或SCellIndex等信息元素(Information Element，IE)指示；而若小区的标识对应PCI(Physical Cell Identity，物理小区标识)，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。
预定义规则可以规定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个被调度小区为小区#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个被调度小区为小区#2，第4个被调度小区为小区#4；若按照标识由大到小排序，那么第1个被调度小区为小区#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个被调度小区为小区#2，第4个被调度小区为小区#1。
据此，可以根据小区的标识准确地确定小区的排序，进而可以确定第1个调度信息为终端接收所述DCI时所在小区的调度信息，第i个调度信息具体为第i个其他小区的调度信息。
在一个实施例中，所述预定义规则规定第i-1个被调度小区的中心频率小于第i个被调度小区的中心频率；或者，所述预定义规则规定第i-1个被调度小区的中心频率小于第i个被调度小区的中心频率。
关于被调度小区的中心频率，网络设备可以发送信息对终端进行指示，例如发送同步信号块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。
预定义规则可以规定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个被调度小区为小区#3，第2个被调度小区为小区#4，第3个被调度小区为小区#2，第4个被调度小区为小区#1；若按照中心频率由大到小排序，那么第1个被调度小区为小区#3，第2个被调度小区为小区#1，第3个被调度小区为小区#2，第4个被调度小区为小区#4。
据此，可以根据小区的中心频率准确地确定小区的排序，进而可以确定第1个调度信息为终端接收所述DCI时所在小区的调度信息，第i个调度信息具体为第i个其他小区的调度信息。
在一个实施例中，所述预定义规则规定第i-1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i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i-1个被调度小区的中心频率对应的ARFCN大于第i个被调度小区的中心频率对应的ARFCN。
关于被调度小区的ARFCN，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。
预定义规则可以规定根据被调度小区的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个被调度小区为小区#3，第2个被调度小区为小区#4，第3个被调度小区为小区#2，第4个被调度小区为小区#1；若按照ARFCN由大到小排序，那么第1个被调度小区为小区#3，第2个被调度小区为小区#1，第3个被调度小区为小区#2，第4个被调度小区为小区#4。
据此，可以根据小区的ARFCN准确地确定小区的排序，进而可以确定第1个 调度信息为终端接收所述DCI时所在小区的调度信息，第i个调度信息具体为第i个其他小区的调度信息。
