Description

小区确定方法、装置、通信装置和存储介质 技术领域
本公开涉及通信技术领域，具体而言，涉及小区确定方法、小区确定装置、小区确定系统、通信装置和计算机可读存储介质。
背景技术
在相关技术中，调度小区内的一个下行控制信息(Downlink Control Information，DCI)只允许调度一个小区的数据，例如调度物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)、物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)。而随着频率资源的逐步碎片化，同时调度多个小区数据的需求将逐步提升。
发明内容
有鉴于此，本公开的实施例提出了小区确定方法、小区确定装置、小区确定系统、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。
根据本公开实施例的第一方面，提出一种小区确定方法，由终端执行，所述方法包括：确定用于调度多个小区的下行控制信息对应的至少一个小区集合；针对所述至少一个小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区，其中，在所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源。
根据本公开实施例的第二方面，提出一种小区确定方法，由网络设备执行，所述方法包括：确定用于调度多个小区的下行控制信息对应的至少一个小区集合；针对所述至少一个小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区，其中，在所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源。

根据本公开实施例的第四方面，提出一种小区确定装置，所述装置包括：处理模块，被配置确定用于调度多个小区的下行控制信息对应的至少一个小区集合；针对所述至少一个小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区，其中，在所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源。
根据本公开实施例的第五方面，提出一种小区确定系统，包括终端、网络设备，其中所述终端被配置为实现上述由终端执行的小区确定方法，所述网络设备被配置为实现上述由网络设备执行的小区确定方法。
根据本公开实施例的第六方面，提出一种通信装置，包括：处理器；用于存储计算机程序的存储器；其中，当所述计算机程序被处理器执行时，实现上述由终端执行的小区确定方法。
根据本公开实施例的第七方面，提出一种通信装置，包括：处理器；用于存储计算机程序的存储器；其中，当所述计算机程序被处理器执行时，实现上述由网络设备执行的小区确定方法。
根据本公开实施例的第八方面，提出一种计算机可读存储介质，用于存储计算机程序，当所述计算机程序被处理器执行时，实现上述由终端执行的小区确定方法。

根据本公开的实施例，终端可以确定用于调度多个小区的下行控制信息对应的至少一个小区集合，然后针对其中每个第一小区集合，确定第一小区集合中的参考小区，进而后续在用于调度多个小区的下行控制信息调度第一小区集合中的小区时，可以在第一小区集合中的参考小区上确定用于调度多个小区的下行控制信息所占的盲检资源。
由于第一小区集合包含的小区可以有调度小区和被调度小区，在此基础上，第一小区集合中的参考小区，就不限于调度小区了，而是可以包括被调度小区，从而可以在被调度小区上确定用于调度多个小区的下行控制信息所占的盲检资源。据此，有 利于提升终端对于下行控制信息的盲检效率和盲检性能。

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1是根据本公开的实施例示出的一种小区确定方法的示意流程图。本实施例所示的小区确定方法可以由终端执行，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1所示，所述小区确定方法可以包括以下步骤：
在步骤S101中，确定用于调度多个小区的下行控制信息对应的至少一个小区集合；
在步骤S102中，针对所述至少一个小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区，其中，在所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源。
在一个实施例中，在所述至少一个小区集合包含多个小区集合的情况下，多个小区集合之间可以包含相同的小区，或者，多个小区之间不包含相同的小区。
在一个实施例中，用于调度多个小区的下行控制信息例如可以简称为MC-DCI，MC-DCI用于调度多个小区，具体是指可以用于调度多个小区的数据，例如调度多个小区中一个或多个小区的PUSCH、PDSCH等，实现了通过一个DCI对多个小区进行调度。其中，MC表示多小区(Multi-cell)。
在一个实施例中，用于调度多个小区的下行控制信息的格式(format)可以与传统(legacy)DCI的格式(例如DCI format 0_0、DCI format 0_1等)相同，也可以采用新定义的格式，例如DCI format 0_3、DCI format 1_3等。
在一个实施例中，用于调度多个小区的下行控制信息可以通过无线网络临时标识(Radio Network Temporary Identity，RNTI)加扰，例如可以通过小区无线网络临时标识C-RNTI进行加扰，也可以通过新定义的RNTI加扰。
由于用于调度多个小区的下行控制信息可以用于调度多个小区，那么相对于legacy DCI中用于调度单个小区的DCI而言，用于调度多个小区的下行控制信息中信息会相对较多，那么占用的盲检资源也会相对较多。虽然终端可以在调度小区上接收用于调度多个小区(被调度小区)的用于调度多个小区的下行控制信息，但是如果将占用的盲检资源都基于调度小区确定，对于调度小区而言负担过重，不利于保证良好的盲检效率和盲检性能。
根据本公开的实施例，终端可以确定用于调度多个小区的下行控制信息对应的至少一个小区集合，然后针对其中每个第一小区集合，确定第一小区集合中的参考小区，进而后续在用于调度多个小区的下行控制信息调度第一小区集合中的小区时，可以在第一小区集合中的参考小区上确定用于调度多个小区的下行控制信息所占的盲检资源。
例如至少一个小区集合包含第一小区集合set#1、第一小区集合set#2等小区集合，可以确定set#1中的参考小区Cell#1，确定set#2中的参考小区Cell#2。进而后续在接收到用于调度多个小区的下行控制信息时，若确定用于调度多个小区的下行控制信息用于调度set#1中的多个小区，那么可以在Cell#1上确定用于调度多个小区的下行控制信息所占的盲检资源；若确定用于调度多个小区的下行控制信息用于调度set#2中的多个小区，那么可以在Cell#2上确定用于调度多个小区的下行控制信息所占的盲检资源。
由于用于调度多个小区的下行控制信息可以调度多个小区，例如调度第一小区集合中的多个小区。本实施例在这种情况下，可以确定第一小区集合中的参考小区，从而在参考小区上确定用于调度多个小区的下行控制信息调度第一小区集合中的小区时所占的盲检资源，或引入比例系数确定盲检资源，有利于确保终端对于下行控制信息的盲检效率和盲检性能，保证盲检资源分配的公平性。
其中，在确定参考小区后，终端可以确定配置给参考小区的用于调度多个小区的下行控制信息对应的搜索空间(Search Space，SS)的配置和/或控制资源集(CORESET)的配置，进而可以根据SS的配置和/或CORESET的配置确定用于调度多个小区的下行控制信息所占的盲检资源，例如确定盲检用于调度多个小区的下行控制信息的时域资源和频域资源，然后在盲检用于调度多个小区的下行控制信息的时隙(slot)或时间跨度(span)上，计算包括用于调度多个小区的下行控制信息在内的所有DCI(例如用于调度多个小区的下行控制信息和legacy DCI)占用的盲检资源。
需要说明的是，第一小区集合中的参考小区，可以是一个小区，也可以是多个小区，后续通过示例对这两种情况进行说明。
在一个实施例中，所述盲检资源包括以下至少之一：
候选物理下行控制信道PDCCH(Physical Downlink Control Channel)candidates；
控制信道单元CCE(Control Channel Element)。
其中，确定盲检资源，是指确定盲检资源的数目，例如对于上述两种盲检资源而言，是指确定一定时域范围内，例如，一个slot范围或一个PDCCH span范围内所占的PDCCH candidates、CCE中至少一种盲检资源的数目。需要说明的是，本公开中确定的盲检资源并不限于上述PDCCH candidates、CCE，还可以根据需要确定其他盲检资源，例如确定的盲检资源还可以包括盲检(Blind Decoding，BD)，其中，BD是指在一段时长内所占的PDCCH candidates的数目。
以下通过几个实施例对确定所述第一小区集合中的参考小区的方式进行示例性描述。其中，确定所述第一小区集合中的参考小区的方式，可以根据预定义规则(例如协议约定)确定，也可以根据网络设备指示确定，对此，本公开并不限制。
图2是根据本公开的实施例示出的另一种小区确定方法的示意流程图。如图2所示，所述确定所述第一小区集合中的参考小区包括：
在步骤S201中，根据小区标识确定所述第一小区集合中的参考小区。
在一个实施例中，在确定第一小区集合中的参考小区时，可以先确定第一小区集合中每个小区的小区标识(Cell ID)，然后根据每个小区的小区标识，在第一小区集合包含的小区中选择参考小区。
在一个实施例中，所述根据小区标识确定所述第一小区集合中的参考小区包括：
在所述第一小区集合中的参考小区包括一个小区时，确定所述第一小区集合中小区标识最大的小区或小区标识最小的小区为所述第一小区集合中的参考小区；或者，
在所述第一小区集合中的参考小区包括多个小区时，在所述第一小区集合中按照小区标识从大到小的顺序确定多个小区或按照小区标识从小到大的顺序确定多个小区为所述第一小区集合中的参考小区。
在一个实施例中，在所述第一小区集合中的参考小区包括一个小区时，那么根据小区标识确定第一小区集合中的参考小区，可以是将小区标识最大的小区确定为第一小区集合中的参考小区，或者将小区标识最小的小区确定为第一小区集合中的参考小区。
例如第一小区集合包含小区Cell#1(Cell ID为1)、Cell#2(Cell ID为2)、Cell#3(Cell ID为3)、Cell#4(Cell ID为4)。在将小区标识最大的小区确定为第一小区集合中的参考小区时，可以将Cell#4确定为第一小区集合中的参考小区；在将小区标识最小的小区确定为第一小区集合中的参考小区时，可以将Cell#1确定为第一小区集合中的参考小区。
在一个实施例中，在所述第一小区集合中的参考小区包括多个小区时，那么根据小区标识确定第一小区集合中的参考小区，可以在所述第一小区集合中按照小区标识从大到小的顺序确定多个小区为第一小区集合中的参考小区，或者在所述第一小区集合中按照小区标识从小到大的顺序确定多个小区为第一小区集合中的参考小区。
例如第一小区集合包含小区Cell#1(Cell ID为1)、Cell#2(Cell ID为2)、Cell#3(Cell ID为3)、Cell#4(Cell ID为4)，参考小区的数量为2。在将小区标识最大的小区确定为第一小区集合中的参考小区时，可以将Cell#4和Cell#3确定为第一小区集合中的参考小区；在将小区标识最小的小区确定为第一小区集合中的参考小区时，可以将Cell#1和Cell#2确定为第一小区集合中的参考小区。
在一个实施例中，可以在对第一小区集合中的小区按照第一顺序(例如根据预定义规则确定或根据网络指示确定)进行排序，然后根据小区的排序序号确定第一小区集合中的参考小区。例如第一顺序包括但不限于小区标识从大到小、小区标识从小到大的顺序，或者，各个小区配置DCI对应的盲检资源从小到大，或从大到小的顺序， 其中，各个小区配置DCI对应的盲检资源确定方式在后续介绍。
仍以第一小区集合包含Cell#1、Cell#2、Cell#3、Cell#4这4个小区为例，例如第一顺序为按照Cell ID由大到小排序，排序结果为Cell#4、Cell#3、Cell#2、Cell#1。例如将排序序号3的小区确定为第一小区集合的参考小区，可知Cell#2为排序序号3的小区，那么可以将Cell#2确定为第一小区集合的参考小区。
图3是根据本公开的实施例示出的一种小区确定方法的示意流程图。如图3所示，所述确定所述第一小区集合中的参考小区包括：
在步骤S301中，根据所述第一小区集合中每个小区中配置的DCI所占的盲检资源，确定所述第一小区集合中的参考小区。
在一个实施例中，在确定第一小区集合中的参考小区时，可以先确定DCI在所述第一小区集合中每个小区中所占的盲检资源，然后根据DCI在第一小区集合中每个小区中所占的盲检资源确定第一小区集合中的参考小区。
在一个实施例中，所述根据所述第一小区集合中每个小区中配置的DCI所占的盲检资源，确定所述第一小区集合中的参考小区包括：
在所述第一小区集合中的参考小区包括一个小区时，确定所述第一小区集合中DCI所占的盲检资源最少的小区为所述第一小区集合中的参考小区；或者，
在所述第一小区集合中的参考小区包括多个小区时，在所述第一小区集合中按照DCI(为第一小区集合中每个小区分别配置的DCI)所占的盲检资源从小到大的顺序确定多个小区为所述第一小区集合中的参考小区。
其中，每个小区中配置的DCI所占的盲检资源可以是每个小区中配置的legacy DCI所占的盲检资源，也可以是每个小区中配置的全部DCI(例如包括legacy DCI和用于调度多个小区的下行控制信息)所占的盲检资源。
在一个实施例中，以每个小区中配置的legacy DCI所占的盲检资源为例，由于为小区配置的legacy DCI所占的盲检资源越多，在小区配置的DCI对应的盲检资源一定的条件下，用于调度多个小区的下行控制信息所占的盲检资源就越少。因此，在所述第一小区集合中的参考小区包括一个小区时，可以先确定第一小区集合中每个小区上所配置的legacy DCI所占的盲检资源，然后确定legacy DCI所占的盲检资源最少的小区为所述第一小区集合中的参考小区。据此，有利于确保终端在参考小区上对于用于调度多个小区的下行控制信息的盲检能力。
在一个实施例中，以每个小区中配置的全部DCI所占的盲检资源为例，由于为小区配置的全部DCI所占的盲检资源越少，终端的盲检复杂度就会相对较低。因此，在所述第一小区集合中的参考小区包括一个小区时，可以先确定第一小区集合中每个小区上所配置的全部DCI所占的盲检资源，然后确定全部DCI所占的盲检资源最少的小区为所述第一小区集合中的参考小区。据此，有利于降低终端在参考小区上的盲检复杂度。
例如第一小区集合包含小区Cell#1、Cell#2、Cell#3、Cell#4，对于这4个小区，可以确定为每个小区配置的DCI所占的盲检资源，例如为Cell#1配置的DCI所占的盲检资源为R1、为Cell#2配置的DCI所占的盲检资源为R2、为Cell#3配置的DCI所占的盲检资源为R3、为Cell#4配置的DCI所占的盲检资源为R4，这4个盲检资源从小到大的顺序为R2、R3、R4、R1，也即Cell#2上配置的DCI所占盲检资源R2最少，那么可以选择Cell#2作为参考小区，用于确定用于调度多个小区的下行控制信息所占盲检资源。
需要说明的是，在本公开的实施例中，针对某个小区，确定为小区配置的DCI所占的盲检资源，包括但不限于以下两种方式：
方式一：确定为小区配置的搜索空间，对搜索空间中配置的DCI的所有盲检资源(例如PDCCH candidates)求和；
方式二：确定为小区配置的搜索空间，对搜索空间中特定时间单元内对应的DCI的盲检资源求和。其中，特定时间单元可以由预定义规则规定或者由网络设备指示，可以是一个或多个帧、和/或一个或多个子帧、和/或一个或多个时隙、和/或符一个或多个符号，和/或一个或多个PDCCH span。
在一个实施例中，以每个小区中配置的legacy DCI所占的盲检资源为例，由于为小区配置的legacy DCI所占的盲检资源越多，用于调度多个小区的下行控制信息所占的盲检资源就越少。因此，在所述第一小区集合中的参考小区包括多个小区时，可以先确定第一小区集合中每个小区上所配置的legacy DCI所占的盲检资源，然后在第一小区集合中按照legacy DCI所占的盲检资源从小到大的顺序确定多个小区为第一小区集合中的参考小区。据此，有利于确保终端在参考小区上对于用于调度多个小区的下行控制信息的盲检能力。
在一个实施例中，以每个小区中配置的全部DCI所占的盲检资源为例，由于为 小区配置的全部DCI所占的盲检资源越少，终端的盲检复杂度就会相对较低。因此，在所述第一小区集合中的参考小区包括多个小区时，可以先确定第一小区集合中每个小区上所配置的全部DCI所占的盲检资源，然后在第一小区集合中按照全部DCI所占的盲检资源从小到大的顺序确定多个小区为第一小区集合中的参考小区。据此，有利于确保终端在参考小区上对于用于调度多个小区的下行控制信息的盲检能力。
例如参考小区的数量为2，第一小区集合包含小区Cell#1、Cell#2、Cell#3、Cell#4，对于这4个小区，可以确定为每个小区上配置的DCI所占的盲检资源，例如为Cell#1配置的DCI所占的盲检资源为R1、为Cell#2配置的DCI所占的盲检资源为R2、为Cell#3配置的DCI所占的盲检资源为R3、为Cell#4配置的DCI所占的盲检资源为R4，这4个盲检资源从小到大的顺序为R2、R3、R4、R1，也即Cell#2上配置的DCI所占盲检资源R2最少，其次是在Cell#3上配置的DCI所占盲检资源R3最少，那么可以选择Cell#2和Cell#3作为参考小区，用于确定用于调度多个小区的下行控制信息所占盲检资源。所述确定小区配置的DCI所占的盲检资源，上述已介绍，在此不再赘述。
在一个实施例中，所述DCI包括以下至少之一：
传统DCI，也即legacy DCI，例如DCI 0_0、DCI 0_1、DCI 1_0、DCI 1_1、DCI 2_0、DCI 2_1等；
所述小区中配置的所有DCI，例如包括legacy DCI和用于调度多个小区的下行控制信息。
图4是根据本公开的实施例示出的又一种小区确定方法的示意流程图。如图4所示，所述确定所述第一小区集合中的参考小区包括：
在步骤S401中，确定所述第一小区集合中用于确定所述用于调度多个小区的下行控制信息尺寸预算的小区为所述第一小区集合中的参考小区。
在一个实施例中，在用于调度多个小区的下行控制信息调度第一小区集合中的多个小区时，可以通过多个小区中的至少一个小区来确定用于调度多个小区的下行控制信息尺寸(size，也即所占比特的数目)预算(budget)，至少一个小区具体是对DCI(包括用于调度多个小区的下行控制信息在内的DCI)的尺寸进行对齐(对于终端侧而言是推演对齐过程)。
那么在选择参考小区时，可以选择用于确定所述用于调度多个小区的下行控制 信息尺寸预算的至少一个小区为参考小区，那么可以在用于调度多个小区的下行控制信息调度多个小区过程中，需要被调度小区执行的确定操作集中在一个小区上，有利于简化对于小区的配置逻辑。
图5是根据本公开的实施例示出的又一种小区确定方法的示意流程图。如图5所示，所述确定所述第一小区集合中的参考小区包括：
在步骤S501中，在所述第一小区集合中确定配置了所述用于调度多个小区的下行控制信息对应搜索空间的小区为所述第一小区集合中的参考小区。
在一个实施例中，在确定第一小区集合中的参考小区时，可以先确定调度第一小区集合内的小区的用于调度多个小区的下行控制信息对应的搜索空间，然后在第一小区集合包含的小区中确定配置了所述用于调度多个小区的下行控制信息对应搜索空间的小区为参考小区。例如搜索空间为SS#1，也即标识为1的SS，那么可以在第一小区集合包含的小区中确定配置了标识为1的SS的小区(可以是一个或多个小区)为参考小区。
需要说明的是，上述几种确定第一小区集合中的参考小区的实施例，可以分别实现，也可以根据需要进行结合，例如可以在第一小区集合中确定配置了用于调度多个小区的下行控制信息对应搜索空间的小区，若确定了多个小区，那么可以进一步在多个小区中确定分别配置的DCI所占盲检资源最少的小区为参考小区。
图6是根据本公开的实施例示出的又一种小区确定方法的示意流程图。如图6所示，在所述第一小区集合中的参考小区包括多个小区时，所述在所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源包括：
在步骤S601中，在所述第一小区集合中的参考小区中的每个小区上分别确定配置的用于调度多个小区的下行控制信息所占的盲检资源。
在一个实施例中，在参考小区包括多个小区的情况下，在这多个小区中的每个小区上，可以分别确定用于调度多个小区的下行控制信息所占的盲检资源。
以第一小区集合包含Cell#1、Cell#2、Cell#3、Cell#4为例。
若确定的参考小区为Cell#1、Cell#2，那么可以在Cell#1确定用于调度多个小区的下行控制信息所占的盲检资源，以及在Cell#2确定用于调度多个小区的下行控制信息所占的盲检资源。
若第一小区集合中的小区都被确定为参考小区，那么可以在Cell#1确定用于调度多个小区的下行控制信息所占的盲检资源，在Cell#2确定用于调度多个小区的下行控制信息所占的盲检资源，在Cell#3确定用于调度多个小区的下行控制信息所占的盲检资源，在Cell#4确定用于调度多个小区的下行控制信息所占的盲检资源。
在一个实施例中，所述在所述第一小区集合中的参考小区中的每个小区上分别确定配置的用于调度多个小区的下行控制信息所占的盲检资源包括：根据在每个所述小区上的确定结果和量化系数确定所述盲检资源。
在所述第一小区集合中的参考小区中的每个小区上分别确定配置的用于调度多个小区的下行控制信息所占的盲检资源的情况下，可以对于每个小区的确定结果(也即确定得到的盲检资源)，可以经过量化系数进行处理(例如根据量化系数对确定结果相乘、相除、相加、相减、开平方、取对数等算法处理)后，作为最终的盲检资源。例如对于某个小区上的确定结果，可以乘以量化系数后作为在这个小区上最终确定的盲检资源。
在一个实施例中，所述量化系数根据所述参考小区包括的多个小区(例如第一小区集合中的全部小区或部分小区)的数量确定，例如量化系数可以为K分之一，其中，K为参考小区包含小区数量。据此，有利于降低在多个小区上确定用于调度多个小区的下行控制信息所占的盲检资源的整体负担。
以第一小区集合包含Cell#1、Cell#2、Cell#3、Cell#4为例。
若确定的参考小区为Cell#1、Cell#2，那么量化系数为1/2。在Cell#1确定用于调度多个小区的下行控制信息所占的盲检资源的确定结果A，可以乘以1/2得到A/2作为在Cell#1确定的用于调度多个小区的下行控制信息所占的盲检资源；在Cell#2确定用于调度多个小区的下行控制信息所占的盲检资源得的确定结果B，可以乘以1/2得到B/2作为在Cell#1确定的用于调度多个小区的下行控制信息所占的盲检资源。
若确定的参考小区为Cell#1、Cell#2、Cell#3、Cell#4，那么量化系数为1/4。在Cell#1确定用于调度多个小区的下行控制信息所占的盲检资源的确定结果A，可以乘以1/4得到A/4作为在Cell#1确定的用于调度多个小区的下行控制信息所占的盲检资源；在Cell#2确定用于调度多个小区的下行控制信息所占的盲检资源得的确定结果B，可以乘以1/4得到B/4作为在Cell#1确定的用于调度多个小区的下行控制信息所占的盲检资源；在Cell#3确定用于调度多个小区的下行控制信息所占的盲检资源的确定 结果C，可以乘以1/4得到C/4作为在Cell#3确定的用于调度多个小区的下行控制信息所占的盲检资源；在Cell#4确定用于调度多个小区的下行控制信息所占的盲检资源得的确定结果D，可以乘以1/4得到D/4作为在Cell#4确定的用于调度多个小区的下行控制信息所占的盲检资源。
在一个实施例中，在所述至少一个小区集合包括多个小区集合，且多个小区集合之间存在交集小区时，若多个所述第一小区集合包含相同的参考小区，在所述相同的参考小区上确定所述用于调度多个小区的下行控制信息调度多个所述第一小区集合中每个第一小区集合中的小区时所占的盲检资源。
在一个实施例中，至少一个小区集合为多个小区集合的情况下，多个小区集合之间可以存在交集小区(包含相同的小区)，也可以不存在交集小区(不包含相同的小区)。
例如以两个小区集合为例。
若小区集合set#1为{Cell#1、Cell#2、Cell#3}，小区集合set#2为{Cell#1、Cell#4、Cell#5}，那么set#1和set#2之间存在交集{Cell#1}，那么交集小区为Cell#1。
若小区集合set#1为{Cell#1、Cell#2、Cell#3}，小区集合set#3为{Cell#4、Cell#5、Cell#6}，那么set#1和set#3之间不存在交集。
在多个小区集合之间存在交集小区的情况下，那么针对多个小区集合中每个第一小区集合确定参考小区时，就可能确定到相同的参考小区。那么在这种情况下，可以在这个相同的参考小区上，确定用于调度多个小区的下行控制信息调度存在交集为该相同的参考小区的每个第一小区集合中小区时，所占的盲检资源。在这种情况下，在相同的参考小区上确定的用于调度多个小区的下行控制信息所占的盲检资源，就是针对每个第一小区集合确定的用于调度多个小区的下行控制信息所占盲检资源之和。
例如确定上述set#1中的参考小区为Cell#1，确定上述set#2中的参考小区也为Cell#1，Cell#1就是相同的参考小区，那么在Cell#1上确定用于调度多个小区的下行控制信息在调度set#1中多个小区时用于调度多个小区的下行控制信息所占的盲检资源，例如为A，以及在Cell#1确定用于调度多个小区的下行控制信息在调度set#2中多个小区时用于调度多个小区的下行控制信息所占的盲检资源，例如为B。那么在Cell#1上确定的用于调度多个小区的下行控制信息所占的盲检资源就是A与B之和。
需要说明的是，在本公开的实施例中，针对某个小区，确定为小区配置的用于 调度多个小区的下行控制信息所占的盲检资源，包括但不限于以下两种方式：
方式一：确定为小区配置的搜索空间，对搜索空间中用于调度多个小区的下行控制信息的所有盲检资源(例如PDCCH candidates)求和；
方式二：确定为小区配置的搜索空间，对搜索空间中特定时间单元内用于调度多个小区的下行控制信息的盲检资源求和。其中，特定时间单元可以由预定义规则规定或者由网络设备指示，可以是一个或多个帧、和/或一个或多个子帧、和/或一个或多个时隙、和/或符一个或多个号。
在一个实施例中，在所述至少一个小区集合包括多个小区集合，且多个小区集合之间存在交集小区时，所述针对所述至少一个小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区包括：
针对多个所述第一小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区，且每个第一小区集合中的参考小区不同。
在一个实施例中，根据上述实施例可知，在至少一个小区集合包括多个小区集合，且多个小区集合之间存在交集小区时，针对多个小区集合中每个第一小区集合确定参考小区时，就可能确定到相同的参考小区。那么就需要在这个相同的参考小区上确定用于调度多个小区的下行控制信息调度存在交集为该相同的参考小区的每个第一小区集合中小区时，所占的盲检资源。虽然有利于简化配置逻辑，但是对于相同的参考小区而言确定负担较大。
因此，在考虑小区确定负担角度，本实施例在至少一个小区集合包括多个小区集合，且多个小区集合之间存在交集小区时，可以在每个第一小区集合中确定不同的参考小区，从而避免导致某一个参考小区的确定负担过大。
例如，对于多个小区集合：
首先，可以定义小区集合的排序方式(可以称作优先级)，例如按照小区集合的标识(id)从小到大对小区集合进行排序，或者按照小区集合的标识从大到小对小区集合进行排序，或者按照为小区集合中一个或多个小区配置的DCI所占盲检资源从大到小进行排序，或者按照为小区集合中一个或多个小区配置的DCI所占盲检资源从小到大进行排序。以下主要以按照小区集合的标识从小到大对小区集合进行排序为例进行描述。
其次，对于排序后的集合n(标识为n)，确定集合n所包含的小区，以及确 定所有标识小于n的集合m(可以是一个或多个小区)所对应的参考小区，其中，可以在参考小区上确定所述MC DCI调度集合m中多个小区时，用于调度多个小区的下行控制信息所占的盲检资源。
然后，确定小区集合n对应的第二小区集合，其中，若所述集合m中的参考小区属于小区集合n，则重新确定第二小区集合，且第二小区集合不包括所述参考小区，也即，第二小区集合等于集合n所包含的所有小区排除掉所述属于集合n的参考小区(可以是被确定为集合m中的参考小区)之后的小区范围。
最后，在第二小区集合包含的小区中，确定参考小区(可以参考前述实施例)，确定的参考小区用于确定用于调度多个小区的下行控制信息在调度集合n中的多个小区时，用于调度多个小区的下行控制信息所占的盲检资源。
以基于小区id号确定参考小区为例，上述过程通过伪代码标识如下：
确定第一小区集合索引γ(j)，其中,所述γ(j)随着j(j＝0,1,2,…)的增加而逐渐增加；
Initialγ(0)，定义参考小区对应集合

else；
γ(j)＝γ(j)\n j；
Return 1
j＝j+1.
以三个第一小区集合为例，例如第一小区集合包括set#1为{Cell#1、Cell#2、 Cell#3}，set#2为{Cell#1、Cell#2、Cell#4}，set#3为{Cell#3、Cell#4、Cell#5}。按照小区集合的标识从小到大对小区集合进行排序为set#1、set#2、set#3。例如确定参考小区的方式为确定第一小区集合中小区标识最小的小区为参考小区。
首先在set#1(也即γ(1)对应小区集合)中确定参考小区，以第一小区集合内cell id最小对应的小区为例，例如确定set#1中的参考小区为Cell#1，则Cell#1属于集合θ；
然后在set#2(也即γ(2)对应小区集合)中确定参考小区，由于set#2内的Cell#1属于集合θ，那么将set#2重新定义为排除掉Cell#1后的其他所有剩余小区的集合，即，set#2重新定义为{Cell#2、Cell#4}。在set#2中选择小区标识最小的小区Cell#2，且Cell#2不属于集合θ，那么将Cell#2作为set#2中的参考小区，重新定义确集合θ，使得Cell#2属于集合θ；
接下来在set#3(也即γ(3)对应小区集合)中确定参考小区，考虑到set#3内不包含属于集合θ的小区，则确定set#3内cell id最小对应的小区为Cell#3，由于Cell#3不属于集合θ，那么Cell#3可以作为set#3中的参考小区，重新定义确集合θ，使得Cell#2属于集合θ。
据此，可以针对上述三个第一小区集合分别确定每个第一小区集合中的参考小区，并且能够保证每个第一小区集合中的参考小区不同。
下面通过几个实施例，对确定用于调度多个小区的下行控制信息对应的至少一个小区集合的方式进行示例性说明。
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对应的至少一个小区集合包括：
确定所述多个小区(例如用于调度多个小区的下行控制信息所能调度的小区)中每个小区的配置参数，其中，所述配置参数包括但不限于集合标识、小区标识、序号、载波指示域(Carrier Indicator Field，CIF)；
确定具有相同配置参数的小区属于用于调度多个小区的下行控制信息对应的一个小区集合。
例如以4个小区Cell#1、Cell#2、Cell#3、Cell#4，配置参数包括CIF为例，可以确定为这4个小区中每个小区配置的CIF(例如根据无线资源控制RRC信令确定)。例如为Cell#1配置的CIF为01，为Cell#2配置的CIF为01，为Cell#3配置的CIF为 02，为Cell#4配置的CIF为02，那么可以确定Cell#1和Cell#2具有相同的CIF，Cell#3和Cell#4具有相同的CIF，从而将Cell#1和Cell#2划分为一个用于调度多个小区的下行控制信息对应的小区集合{Cell#1、Cell#2}，将Cell#3和Cell#4划分为另一个用于调度多个小区的下行控制信息对应的小区集合{Cell#3、Cell#4}。
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对应的至少一个小区集合包括：
在第一小区接收网络设备发送的指示信息；根据在多个所述第一小区接收到的指示信息确定多个小区组；确定所述第一小区在所述多个小区组中所属的目标小区组，以及所述目标小区组所属的小区组集合；确定所述小区组集合对应的小区集合。
终端可以在多个第一小区接收网络设备发送的指示信息，其中，所述指示信息可以指示接收指示信息时所在的第一小区对应的载波指示域CIF的值与调度小区标识之间的关联关系，终端可以根据每个第一小区对应的关联关系，确定多个小区组。其中，所述关联关系具体可以是调度小区内载波指示域(cif-InScheduingCell)的值与调度小区标识之间的关联关系。
终端可以基于以下方式确定第一小区是否为在第二小区接收到的用于调度多个小区的下行控制信息所调度的小区：
确定RRC消息中信息元素(Information Element，IE)服务小区配置(ServingCellConfig)，然后确定服务小区配置中的跨载波调度配置(CrossCarrierSchedulingConfig)，再在跨载波调度配置中确定调度小区信息(schedulingCellInfo)，进而在schedulingCellInfo指示值为其他(other)时，进一步确定schedulingCellInfo中调度小区标识(schedulingCellId)和cif-InScheduingCell。
在RRC消息内配置的调度小区标识与第二小区的标识相同，且RRC消息内配置的cif-InScheduingCell的值与在第二小区接收到的用于调度多个小区的下行控制信息中CIF的值相同时，可以确定在第二小区接收到的用于调度多个小区的下行控制信息用于调度第一小区。
所述关联关系可以定义多个载波指示域的值与多个调度小区标识之间的对应关系，并不限于一个载波指示域的值关联一个调度小区标识，因此网络设备根据所述关联关系向终端发送用于调度多个小区的下行控制信息时，有利于提高用于调度多个小区的下行控制信息对第一小区的调度灵活度。例如，网络设备可以根据需要调度的 第一小区对应的关联关系，在发送的用于调度多个小区的下行控制信息中设置CIF值，从而动态调整被调度的多个小区(小区组)。
图7是根据本公开的实施例示出的另一种应用场景示意图。
如图7所示，以Cell#0(小区标识为0)、Cell#1(小区标识为1)和Cell#2(小区标识为2)这3个小区为例，网络设备通过RRC消息携带指示信息。
网络设备在Cell#0向终端发送的RRC消息中携带的关联关系为table1-0，在Cell#1向终端发送的RRC消息中携带的关联关系为table1-1，在Cell#2向终端发送的RRC消息中携带的关联关系为table1-2。
table1-0包含的关联关系为：载波指示域的值为0对应调度小区标识为2；
table1-1包含的关联关系为：载波指示域的值为1对应调度小区标识0，载波指示域的值为2对应调度小区标识为0；那么网络设备在小区标识为0的第二小区中向终端发送的用于调度多个小区的下行控制信息中CIF的值为1时，可以实现对第一小区进(例如Cell#1)行调度，在小区标识为0的第二小区中向终端发送的用于调度多个小区的下行控制信息中CIF的值为2时，也可以实现对第一小区(例如Cell#1)进行调度。其中，CIF的值的范围可以是0至7，当然，也可以根据需要调整。
table1-2包含的关联关系为：载波指示域的值为1对应调度小区标识0，载波指示域的值为3对应调度小区标识0。那么网络设备在小区标识为0的第二小区中向终端发送的用于调度多个小区的下行控制信息中CIF的值为1时，可以实现对第一小区(例如Cell#2)进行调度，在小区标识为2的第二小区中向终端发送的用于调度多个小区的下行控制信息中CIF的值为3时，也可以实现对第一小区(例如Cell#2)进行调度。
其中，由于table1-0是在调度小区Cell#0接收到的关联关系，而在调度小区接收到的用于调度多个小区的下行控制信息是可以用于自调度的，也即在Cell#0接收到的用于调度多个小区的下行控制信息可以用于调度Cell#0本身，所以Cell#0对应的关联关系除了table1-0中包含的对应关系，还可以额外包含：载波指示域的值为0对应调度小区标识为0、载波指示域的值为1对应调度小区标识为0、载波指示域的值为2对应调度小区标识为0、载波指示域的值为3对应调度小区标识为0。
需要说明的是，图6所示的表格(table)中空白的部分，也可以设置载波指示域的值和调度小区标识，只不过本实施例在示例过程中并未用到，因此没有示出。另 外，表格中的行数并不限于图中所示4行，可以根据需要减少或增加行数。
基于上述关联关系可以确定，载波指示域的值为0(00)时，用于调度多个小区的下行控制信息可以调度Cell#0；载波指示域的值为1(01)时，用于调度多个小区的下行控制信息可以调度Cell#0、Cell#1、Cell#2；载波指示域的值为2(10)时，用于调度多个小区的下行控制信息可以调度Cell#0和Cell#1；载波指示域的值为3(11)时，用于调度多个小区的下行控制信息可以调度Cell#0和Cell#2。据此，终端可以确定的载波指示域的值与所调度小区之间的关系如下表1所示：
CIF 小区组
00 {0}
01 {0,1,2}
10 {0,1}
11 {0,2}
表1
其中，小区组可以是在每个第一小区接收到的指示信息所指示关联关系中，每个载波指示域的值(也可以通过其他域的值进行指示)对应的小区分别构成的小区组，如表1所示，多个小区组为{0}、{0,1,2}、{0,1}、{0,2}。为方便示例，集合中仅记载小区标识。
可以理解的是，本公开所有实施例所示的表格中每一个元素都是独立存在的，这些元素被示例性的列在同一张表格中，但是并不代表表格中的所有元素必须根据表格中所示的同时存在。其中每一个元素的值，是不依赖于表格中任何其他元素值。因此本领域内技术人员可以理解，该表格中的每一个元素的取值都是一个独立的实施例。
由于小区组也有所属的小区组集合，而小区组集合则可以对应小区集合，因此，终端在确定多个小区组之后，可以进一步确定第一小区在多个小区组中所属的目标小区组，进而确定目标小区组所属的小区组集合，以及小区组集合对应的小区集合，那么就可以确定第一小区属于所确定的小区集合，也即用于调度多个小区的下行控制信息对应的小区集合。
其中，不同小区组集合中的小区组所包含的小区是不同的，例如小区组集合#1包含小区组#1和小区组#2，小区组集合#2包含小区组#3和小区组#4，那么小区组#1 和小区组#2所包含的小区，与小区组#3和小区组#4所包含的小区是不同的。
在一个实施例中，所述确定所述小区组集合对应的小区集合包括：根据所述多个小区组确定至少一个小区组集合，其中，第一小区组集合中的第一小区组，至少与所述第一小区组集合中的第二小区组包含相同的小区；确定所述至少一个小区组集合中一个小区组集合中的小区组包含的小区构成一个小区集合。
终端在确定多个小区组之后，可以根据多个小区组确定小区组集合，其中，可以将包含相同小区的小区组，划分在同一个小区组集合中，例如第一小区组第二小区组包含相同的小区，那么可以将第一小区组和第二小区组划分在同一个小区组集合中，例如划分在第一小区组集合。
然后可以在其他小区组中确定与第一小区组集合中任一个小区组包含相同小区的小区组，然后将确定的小区组也划分在第一小区组集合中。以此类推，可以完成第一小区组集合的确定。进而根据确定第一小区组集合的方式，确定其他小区组集合。
需要说明的是，同一个小区组集合中的第一小区组和第二小区组不同，第一小区组和第二小区组并非特指某个小区，而是一个小区组集合中的任意一个小区组。
例如以以下几个小区组为例确定小区组集合：
{0,1,2,3},{3},{5,6,7},{3,4,5,6},{8,9},{8}；
首先可以考虑其中任一个小区组，例如首先考虑小区组{0,1,2,3}，可以确定小区组{3}和小区组{3,4,5,6}与小区组{0,1,2,3}包含相同的小区Cell#3，那么可以将{3}、{3,4,5,6}、{0,1,2,3}这3个小区组划分为同一个小区组集合中，例如称作第一小区组集合。
进而再判断其他小区组中，与第一小区组集合中任一个小区组包含相同小区的小区组，可以确定小区组{5,6,7}与第一小区组中的小区组{3,4,5,6}包含相同的小区Cell#5和Cell#6，那么可以将小区组{5,6,7}也划分到第一小区组集合中。
而小区组{8,9}和{8}与第一小区组集合中的任一个小区组均不包含相同的小区，所以第一小区组集合确定完毕，可以继续确定第二小区组集合。例如按照上述方式可以确定第二小区组集合包含小区组{8,9}和{8}。
针对小区组，例如在Cell#1、Cell#2、Cell#3、Cell#4接收到的指示信息包含小区集合的标识为1，在Cell#5、Cell#6、Cell#7、Cell#8接收到的指示信息包含小区集 合的标识为2，终端确定Cell#1、Cell#2、Cell#3、Cell#4属于标识为1的小区集合(cell set id＝1)，以及确定Cell#5、Cell#6、Cell#7、Cell#8属于标识为2的小区集合(cell set id＝2)。
后续终端在调度小区接收到的用于调度多个小区的下行控制信息用于调度多个小区Cell#1、Cell#2、Cell#3、Cell#4的用于调度多个小区的下行控制信息、也可以用于调度多个小区Cell#2、Cell#3，在调度小区接收到的另一个用于调度多个小区的下行控制信息可以用于调度多个小区Cell#5、Cell#6、Cell#7、Cell#8，也可以用于调度多个小区Cell#6、Cell#7。那么可以确定4个小区组{1,2,3,4}、{2,3}、{5,6,7,8}、{6,7}，以及两个小区组集合{{1,2,3,4}、{2,3}}、{{5,6,7,8}、{6,7}}。其中，不同的小区组集合，可以是不同小区发送的用于调度多个小区的下行控制信息所调度的小区确定。
在一个实施例中，确定小区组集合对应小区集合的方式，可以是确定小区组集合中的小区组包含的小区，进而将确定的小区构成的集合作为小区组集合对应的小区集合。
图8是根据本公开的实施例示出的又一种应用场景示意图。
如图8所示，以前述实施例所确定的第一小区组集合和第二小区组集合为例，其中，第一小区组集合为{{0,1,2,3},{3},{3,4,5,6},{5,6,7}}，第二小区组集合为{{8,9},{8}}。
可以确定第一小区组集合中的小区组包含的小区为Cell#0、Cell#1、Cell#2、Cell#3、Cell#4、Cell#5、Cell#6、Cell#7，那么可以确定这些小区构成的小区集合为{0,1,2,3,4,5,6,7}，也即第一小区组集合对应的小区集合为{0,1,2,3,4,5,6,7}，类似地，可以确定第二小区组集合对应的小区集合为{8,9}。那么用于调度多个小区的下行控制信息对应的至少一个小区集合包括小区集合{0,1,2,3,4,5,6,7}和小区集合{8,9}。
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对应的至少一个小区集合包括：在第一小区接收网络设备发送的指示信息；根据在多个所述第一小区接收到的指示信息确定多个小区组；确定小区组为小区集合。
其中，确定多个小区组的方式与前述实施例类似，此处不再赘述，本实施例与前述实施例不同之处在于，是直接将小区组确定为小区集合，而没有确定小区组所属的小区集合。例如在根据指示信息确定表1后，就可以将表1中的多个小区组{0}、{0,1,2}、{0,1}、{0,2}分别作为小区集合，也即用于调度多个小区的下行控制信息对应 的至少一个小区集合包括{0}、{0,1,2}、{0,1}、{0,2}这4个集合。
图9是根据本公开的实施例示出的一种小区确定方法的示意流程图。本实施例所示的小区确定方法可以由网络设备执行，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9所示，所述小区确定方法可以包括以下步骤：
在步骤S901中，确定用于调度多个小区的下行控制信息对应的至少一个小区集合；
在步骤S902中，针对所述至少一个小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区，其中，在所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源。
在一个实施例中，在所述至少一个小区集合包含多个小区集合的情况下，多个小区集合之间可以包含相同的小区，或者，多个小区之间不包含相同的小区。
在一个实施例中，用于调度多个小区的下行控制信息例如可以简称为MC-DCI，MC-DCI用于调度多个小区，具体是指可以用于调度多个小区的数据，例如调度多个小区中一个或多个小区的PUSCH、PDSCH等，实现了通过一个DCI对多个小区进行调度。其中，MC表示多小区(Multi-cell)。
在一个实施例中，用于调度多个小区的下行控制信息的格式(format)可以与传统(legacy)DCI的格式(例如DCI format 0_0、DCI format 0_1等)相同，也可以采用新定义的格式，例如DCI format 0_3、DCI format 1_3等。
在一个实施例中，用于调度多个小区的下行控制信息可以通过无线网络临时标识(Radio Network Temporary Identity，RNTI)加扰，例如可以通过小区无线网络临时标识C-RNTI进行加扰，也可以通过新定义的RNTI加扰。
由于用于调度多个小区的下行控制信息可以用于调度多个小区，那么相对于legacy DCI中用于调度单个小区的DCI而言，用于调度多个小区的下行控制信息中信息会相对较多，那么占用的盲检资源也会相对较多。虽然终端可以在调度小区上用于调度多个小区(被调度小区)的用于调度多个小区的下行控制信息，但是如果将占用的盲检资源都基于调度小区确定，对于调度小区而言负担过重，不利于保证良好的盲 检效率和盲检性能。
根据本公开的实施例，网络设备在确定用于调度多个小区的下行控制信息对应的至少一个小区集合后，可以针对其中每个第一小区集合，确定第一小区集合中的参考小区，进而后续在用于调度多个小区的下行控制信息调度第一小区集合中的小区时，可以在第一小区集合中的参考小区上确定用于调度多个小区的下行控制信息所占的盲检资源。
例如至少一个小区集合包含第一小区集合set#1、第一小区集合set#2等小区集合，可以确定set#1中的参考小区Cell#1，确定set#2中的参考小区Cell#2。进而后续在接收到用于调度多个小区的下行控制信息时，若确定用于调度多个小区的下行控制信息用于调度set#1中的多个小区，那么可以在Cell#1上确定用于调度多个小区的下行控制信息所占的盲检资源；若确定用于调度多个小区的下行控制信息用于调度set#2中的多个小区，那么可以在Cell#2上确定用于调度多个小区的下行控制信息所占的盲检资源。
由于用于调度多个小区的下行控制信息可以调度多个小区，例如调度第一小区集合中的多个小区。本实施例在这种情况下，可以确定第一小区集合中的参考小区，从而在参考小区上确定用于调度多个小区的下行控制信息调度第一小区集合中的小区时所占的盲检资源，有利于确保后续终端对于下行控制信息的盲检效率和盲检性能。
终端在确定第一小区集合中的参考小区后，可以在所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源，在所确定的盲检资源超出盲检能力时，可以丢弃(drop)一部分对应于配置DCI的盲检资源，在丢弃的这部分盲检资源上不做DCI的盲检。
而网络设备确定第一小区集合中的参考小区，并确定在所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源，可以进一步确定后续终端可能丢弃掉的盲检资源，有利于提升调度的灵活性和有效性。
其中，在确定参考小区后，网路设备可以确定配置给参考小区的用于调度多个小区的下行控制信息对应的搜索空间SS的配置和/或控制资源集CORESET的配置，进而可以根据SS的配置和/或CORESET的配置确定用于调度多个小区的下行控制信息所占的盲检资源，例如确定盲检用于调度多个小区的下行控制信息的时域资源和频 域资源，然后在盲检用于调度多个小区的下行控制信息的时隙(slot)或时间跨度(span)上，计算包括用于调度多个小区的下行控制信息在内的所有DCI(例如用于调度多个小区的下行控制信息和legacy DCI)占用的盲检资源。
需要说明的是，第一小区集合中的参考小区，可以是一个小区，也可以是多个小区，后续通过示例对这两种情况进行说明。
在一个实施例中，所述盲检资源包括以下至少之一：
候选物理下行控制信道PDCCH candidates；
控制信道单元CCE。
其中，确定盲检资源，是指确定盲检资源的数目，例如对于上述两种盲检资源而言，是指确定一定时域范围内，例如，一个slot范围或一个PDCCH span范围内所占的PDCCH candidates、CCE中至少一种盲检资源的数目。需要说明的是，本公开中确定的盲检资源并不限于上述PDCCH candidates、CCE，还可以根据需要确定其他盲检资源，例如确定的盲检资源还可以包括盲检BD，其中，BD是指在一段时长内所占的PDCCH candidates的数目。
以下通过几个实施例对确定所述第一小区集合中的参考小区的方式进行示例性描述。其中，确定所述第一小区集合中的参考小区的方式，可以根据预定义规则(例如协议约定)确定，也可以根据网络设备指示确定，对此，本公开并不限制。
在一个实施例中，所述确定所述第一小区集合中的参考小区包括：根据小区标识确定所述第一小区集合中的参考小区。
在一个实施例中，在确定第一小区集合中的参考小区时，可以先确定第一小区集合中每个小区的小区标识(Cell ID)，然后根据每个小区的小区标识，在第一小区集合包含的小区中选择参考小区。
在一个实施例中，所述根据小区标识确定所述第一小区集合中的参考小区包括：在所述第一小区集合中的参考小区包括一个小区时，确定所述第一小区集合中小区标识最大的小区或小区标识最小的小区为所述第一小区集合中的参考小区；或者，在所述第一小区集合中的参考小区包括多个小区时，在所述第一小区集合中按照小区标识从大到小的顺序确定多个小区或按照小区标识从小到大的顺序确定多个小区为所述第一小区集合中的参考小区。
在一个实施例中，在所述第一小区集合中的参考小区包括一个小区时，那么根据小区标识确定第一小区集合中的参考小区，可以是将小区标识最大的小区确定为第一小区集合中的参考小区，或者将小区标识最小的小区确定为第一小区集合中的参考小区。
例如第一小区集合包含小区Cell#1(Cell ID为1)、Cell#2(Cell ID为2)、Cell#3(Cell ID为3)、Cell#4(Cell ID为4)。在将小区标识最大的小区确定为第一小区集合中的参考小区时，可以将Cell#4确定为第一小区集合中的参考小区；在将小区标识最小的小区确定为第一小区集合中的参考小区时，可以将Cell#1确定为第一小区集合中的参考小区。
在一个实施例中，在所述第一小区集合中的参考小区包括多个小区时，那么根据小区标识确定第一小区集合中的参考小区，可以在所述第一小区集合中按照小区标识从大到小的顺序确定多个小区为第一小区集合中的参考小区，或者在所述第一小区集合中按照小区标识从小到大的顺序确定多个小区为第一小区集合中的参考小区。
例如第一小区集合包含小区Cell#1(Cell ID为1)、Cell#2(Cell ID为2)、Cell#3(Cell ID为3)、Cell#4(Cell ID为4)，参考小区的数量为2。在将小区标识最大的小区确定为第一小区集合中的参考小区时，可以将Cell#4和Cell#3确定为第一小区集合中的参考小区；在将小区标识最小的小区确定为第一小区集合中的参考小区时，可以将Cell#1和Cell#2确定为第一小区集合中的参考小区。
在一个实施例中，可以在对第一小区集合中的小区按照第一顺序(例如根据预定义规则确定或根据网络指示确定)进行排序，然后根据小区的排序序号确定第一小区集合中的参考小区。例如第一顺序包括但不限于小区标识从大到小、小区标识从小到大。
仍以第一小区集合包含Cell#1、Cell#2、Cell#3、Cell#4这4个小区为例，例如第一顺序为按照Cell ID由大到小排序，排序结果为Cell#4、Cell#3、Cell#2、Cell#1。例如将排序序号3的小区确定为第一小区集合的参考小区，可知Cell#2为排序序号3的小区，那么可以将Cell#2确定为第一小区集合的参考小区。
在一个实施例中，所述确定所述第一小区集合中的参考小区包括：根据所述第一小区集合中每个小区中配置的DCI所占的盲检资源，确定所述第一小区集合中的参考小区。
在一个实施例中，在确定第一小区集合中的参考小区时，可以先确定DCI在所述第一小区集合中每个小区中所占的盲检资源，然后根据DCI在第一小区集合中每个小区中所占的盲检资源确定第一小区集合中的参考小区。
在一个实施例中，所述根据所述第一小区集合中每个小区中配置的DCI所占的盲检资源，确定所述第一小区集合中的参考小区包括：在所述第一小区集合中的参考小区包括一个小区时，确定所述第一小区集合中DCI所占的盲检资源最少的小区为所述第一小区集合中的参考小区；或者，在所述第一小区集合中的参考小区包括多个小区时，在所述第一小区集合中按照DCI(为第一小区集合中每个小区分别配置的DCI)所占的盲检资源从小到大的顺序确定多个小区为所述第一小区集合中的参考小区。
其中，每个小区中配置的DCI所占的盲检资源可以是每个小区中配置的legacy DCI所占的盲检资源，也可以是每个小区中配置的全部DCI(例如包括legacy DCI和用于调度多个小区的下行控制信息)所占的盲检资源。
在一个实施例中，以每个小区中配置的legacy DCI所占的盲检资源为例，由于为小区配置的legacy DCI所占的盲检资源越多，在小区配置的DCI对应的盲检资源一定的条件下，用于调度多个小区的下行控制信息所占的盲检资源就越少，因此，在所述第一小区集合中的参考小区包括一个小区时，可以先确定第一小区集合中每个小区上所配置的legacy DCI所占的盲检资源，然后确legacy定DCI所占的盲检资源最少的小区为所述第一小区集合中的参考小区。据此，有利于确保终端在参考小区上对于用于调度多个小区的下行控制信息的盲检能力。
在一个实施例中，以每个小区中配置的全部DCI所占的盲检资源为例，由于为小区配置的全部DCI所占的盲检资源越少，终端的盲检复杂度就会相对较低。因此，在所述第一小区集合中的参考小区包括一个小区时，可以先确定第一小区集合中每个小区上所配置的全部DCI所占的盲检资源，然后确定全部DCI所占的盲检资源最少的小区为所述第一小区集合中的参考小区。据此，有利于降低终端在参考小区上的盲检复杂度。
例如第一小区集合包含小区Cell#1、Cell#2、Cell#3、Cell#4，对于这4个小区，可以确定为每个小区配置的DCI所占的盲检资源，例如为Cell#1配置的DCI所占的盲检资源为R1、为Cell#2配置的DCI所占的盲检资源为R2、为Cell#3配置的DCI所占的盲检资源为R3、为Cell#4配置的DCI所占的盲检资源为R4，这4个盲检资源从小到大的顺序为R2、R3、R4、R1，也即Cell#2上配置的DCI所占盲检资源R2最少， 那么可以选择Cell#2作为参考小区，用于确定用于调度多个小区的下行控制信息所占盲检资源。
需要说明的是，在本公开的实施例中，针对某个小区，确定为小区配置的DCI所占的盲检资源，包括但不限于以下两种方式：
方式一：确定为小区配置的搜索空间，对搜索空间中DCI的所有盲检资源(例如PDCCH candidates)求和；
方式二：确定为小区配置的搜索空间，对搜索空间中特定时间单元内对应的DCI的盲检资源求和。其中，特定时间单元可以由预定义规则规定或者由网络设备指示，可以是一个或多个帧、和/或一个或多个子帧、和/或一个或多个时隙、和/或符一个或多个符号，和/或一个或多个PDCCH span。
在一个实施例中，以每个小区中配置的legacy DCI所占的盲检资源为例，由于为小区配置的legacy DCI所占的盲检资源越多，用于调度多个小区的下行控制信息所占的盲检资源就越少。因此，在所述第一小区集合中的参考小区包括多个小区时，可以先确定第一小区集合中每个小区上所配置的legacy DCI所占的盲检资源，然后在第一小区集合中按照legacy DCI所占的盲检资源从小到大的顺序确定多个小区为第一小区集合中的参考小区。据此，有利于确保终端在参考小区上对于用于调度多个小区的下行控制信息的盲检能力。
在一个实施例中，以每个小区中配置的全部DCI所占的盲检资源为例，由于为小区配置的全部DCI所占的盲检资源越少，终端的盲检复杂度就会相对较低。因此，在所述第一小区集合中的参考小区包括多个小区时，可以先确定第一小区集合中每个小区上所配置的全部DCI所占的盲检资源，然后在第一小区集合中按照全部DCI所占的盲检资源从小到大的顺序确定多个小区为第一小区集合中的参考小区。据此，有利于确保终端在参考小区上对于用于调度多个小区的下行控制信息的盲检能力。
例如参考小区的数量为2，第一小区集合包含小区Cell#1、Cell#2、Cell#3、Cell#4，对于这4个小区，可以确定为每个小区上配置的DCI所占的盲检资源，例如为Cell#1配置的DCI所占的盲检资源为R1、为Cell#2配置的DCI所占的盲检资源为R2、为Cell#3配置的DCI所占的盲检资源为R3、为Cell#4配置的DCI所占的盲检资源为R4，这4个盲检资源从小到大的顺序为R2、R3、R4、R1，也即Cell#2上配置的DCI所占盲检资源R2最少，其次是在Cell#3上配置的DCI所占盲检资源R3最少， 那么可以选择Cell#2和Cell#3作为参考小区，用于确定用于调度多个小区的下行控制信息所占盲检资源。所述确定小区配置的DCI所占的盲检资源，上述已介绍，在此不再赘述。
在一个实施例中，所述DCI包括以下至少之一：传统DCI；所述小区中配置的所有DCI。
在一个实施例中，所述确定所述第一小区集合中的参考小区包括：确定所述第一小区集合中用于确定所述用于调度多个小区的下行控制信息尺寸预算的小区为所述第一小区集合中的参考小区。
在一个实施例中，在用于调度多个小区的下行控制信息调度第一小区集合中的多个小区时，可以通过多个小区中的至少一个小区来确定用于调度多个小区的下行控制信息尺寸(size，也即所占比特的数目)预算(budget)，至少一个小区具体是对DCI(包括用于调度多个小区的下行控制信息在内的DCI)的尺寸进行对齐。
那么在选择参考小区时，可以选择用于确定所述用于调度多个小区的下行控制信息尺寸预算的至少一个小区为参考小区，那么可以在用于调度多个小区的下行控制信息调度多个小区过程中，需要被调度小区执行的确定操作集中在一个小区上，有利于简化对于小区的配置逻辑。
在一个实施例中，在所述第一小区集合中确定配置了所述用于调度多个小区的下行控制信息对应搜索空间的小区为所述第一小区集合中的参考小区。
在一个实施例中，在确定第一小区集合中的参考小区时，可以先确定调度第一小区集合内的小区的用于调度多个小区的下行控制信息对应的搜索空间，然后在第一小区集合包含的小区中确定配置了所述用于调度多个小区的下行控制信息对应搜索空间的小区为参考小区。例如搜索空间为SS#1，也即标识为1的SS，那么可以在第一小区集合包含的小区中确定配置了标识为1的SS的小区(可以是一个或多个小区)为参考小区。
需要说明的是，上述几种确定第一小区集合中的参考小区的实施例，可以分别实现，也可以根据需要进行结合，例如可以在第一小区集合中确定配置了用于调度多个小区的下行控制信息对应搜索空间的小区，若确定了多个小区，那么可以进一步在多个小区中确定分别配置的DCI所占盲检资源最少的小区为参考小区。
在一个实施例中，在所述第一小区集合中的参考小区包括多个小区时，所述在 所述第一小区集合中的参考小区上确定所述用于调度多个小区的下行控制信息调度所述第一小区集合中的小区时所占的盲检资源包括：在所述第一小区集合中的参考小区中的每个小区上分别确定配置的用于调度多个小区的下行控制信息所占的盲检资源。
在一个实施例中，在参考小区包括多个小区的情况下，在这多个小区中的每个小区上，可以分别确定用于调度多个小区的下行控制信息所占的盲检资源。
以第一小区集合包含Cell#1、Cell#2、Cell#3、Cell#4为例。
若确定的参考小区为Cell#1、Cell#2，那么可以在Cell#1确定用于调度多个小区的下行控制信息所占的盲检资源，以及在Cell#2确定用于调度多个小区的下行控制信息所占的盲检资源。
若第一小区集合中的小区都被确定为参考小区，那么可以在Cell#1确定用于调度多个小区的下行控制信息所占的盲检资源，在Cell#2确定用于调度多个小区的下行控制信息所占的盲检资源，在Cell#3确定用于调度多个小区的下行控制信息所占的盲检资源，在Cell#4确定用于调度多个小区的下行控制信息所占的盲检资源。
在一个实施例中，所述在所述第一小区集合中的参考小区中的每个小区上分别确定配置的用于调度多个小区的下行控制信息所占的盲检资源包括：根据在每个所述小区上的确定结果和量化系数确定所述盲检资源。
在所述第一小区集合中的参考小区中的每个小区上分别确定配置的用于调度多个小区的下行控制信息所占的盲检资源的情况下，可以对于每个小区的确定结果(也即确定得到的盲检资源)，可以经过量化系数进行处理(例如根据量化系数对确定结果相乘、相除、相加、相减、开平方、取对数等算法处理)后，作为最终的得出盲检资源。例如对于某个小区上的确定结果，可以乘以量化系数后作为在这个小区上最终确定的盲检资源。
在一个实施例中，所述量化系数根据所述参考小区包括的多个小区(例如第一小区集合中的全部小区或部分小区)的数量确定，例如量化系数可以为参考小区中包含小区数量K分之一，其中，K为参考小区包含小区数量。据此，有利于降低在多个小区上确定用于调度多个小区的下行控制信息所占的盲检资源的整体负担。
以第一小区集合包含Cell#1、Cell#2、Cell#3、Cell#4为例。
若确定的参考小区为Cell#1、Cell#2，那么量化系数为1/2。在Cell#1确定用于调度多个小区的下行控制信息所占的盲检资源的确定结果A，可以乘以1/2得到A/2 作为在Cell#1确定的用于调度多个小区的下行控制信息所占的盲检资源；在Cell#2确定用于调度多个小区的下行控制信息所占的盲检资源得的确定结果B，可以乘以1/2得到B/2作为在Cell#1确定的用于调度多个小区的下行控制信息所占的盲检资源。
若确定的参考小区为Cell#1、Cell#2、Cell#3、Cell#4，那么量化系数为1/4。在Cell#1确定用于调度多个小区的下行控制信息所占的盲检资源的确定结果A，可以乘以1/4得到A/4作为在Cell#1确定的用于调度多个小区的下行控制信息所占的盲检资源；在Cell#2确定用于调度多个小区的下行控制信息所占的盲检资源得的确定结果B，可以乘以1/4得到B/4作为在Cell#1确定的用于调度多个小区的下行控制信息所占的盲检资源；在Cell#3确定用于调度多个小区的下行控制信息所占的盲检资源的确定结果C，可以乘以1/4得到C/4作为在Cell#3确定的用于调度多个小区的下行控制信息所占的盲检资源；在Cell#4确定用于调度多个小区的下行控制信息所占的盲检资源得的确定结果D，可以乘以1/4得到D/4作为在Cell#4确定的用于调度多个小区的下行控制信息所占的盲检资源。
在一个实施例中，在所述至少一个小区集合包括多个小区集合，且多个小区集合之间存在交集小区时，若多个所述第一小区集合包含相同的参考小区，在所述相同的参考小区上确定所述用于调度多个小区的下行控制信息调度多个所述第一小区集合中每个第一小区集合中的小区时所占的盲检资源。
在一个实施例中，至少一个小区集合为多个小区集合的情况下，多个小区集合之间可以存在交集小区(包含相同的小区)，也可以不存在交集小区(不包含相同的小区)。
例如以两个小区集合为例。
若小区集合set#1为{Cell#1、Cell#2、Cell#3}，小区集合set#2为{Cell#1、Cell#4、Cell#5}，那么set#1和set#2之间存在交集{Cell#1}，那么交集小区为Cell#1。
若小区集合set#1为{Cell#1、Cell#2、Cell#3}，小区集合set#3为{Cell#4、Cell#5、Cell#6}，那么set#1和set#3之间不存在交集。
在多个小区集合之间存在交集小区的情况下，那么针对多个小区集合中每个第一小区集合确定参考小区时，就可能确定到相同的参考小区。那么在这种情况下，可以在这个相同的参考小区上，确定用于调度多个小区的下行控制信息调度存在交集为该相同的参考小区的每个第一小区集合中小区时，所占的盲检资源。在这种情况下， 在相同的参考小区上确定的用于调度多个小区的下行控制信息所占的盲检资源，就是针对每个第一小区集合确定的用于调度多个小区的下行控制信息所占盲检资源之和。
例如确定上述set#1中的参考小区为Cell#1，确定上述set#2中的参考小区也为Cell#1，Cell#1就是相同的参考小区，那么在Cell#1上确定用于调度多个小区的下行控制信息在调度set#1中多个小区时用于调度多个小区的下行控制信息所占的盲检资源，例如为A，以及在Cell#1确定用于调度多个小区的下行控制信息在调度set#2中多个小区时用于调度多个小区的下行控制信息所占的盲检资源，例如为B。那么在Cell#1上确定的用于调度多个小区的下行控制信息所占的盲检资源就是A与B之和。
需要说明的是，在本公开的实施例中，针对某个小区，确定为小区配置的用于调度多个小区的下行控制信息所占的盲检资源，包括但不限于以下两种方式：
方式一：确定为小区配置的搜索空间，对搜索空间中用于调度多个小区的下行控制信息的所有盲检资源(例如PDCCH candidates)求和；
方式二：确定为小区配置的搜索空间，对搜索空间中特定时间单元内用于调度多个小区的下行控制信息的盲检资源求和。其中，特定时间单元可以由预定义规则规定或者由网络设备指示，可以是一个或多个帧、和/或一个或多个子帧、和/或一个或多个时隙、和/或符一个或多个号。
在一个实施例中，在所述至少一个小区集合包括多个小区集合，且多个小区集合之间存在交集小区时，所述针对所述至少一个小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区包括：针对多个所述第一小区集合中的每个第一小区集合，确定所述第一小区集合中的参考小区，且每个第一小区集合中的参考小区不同。
在一个实施例中，根据上述实施例可知，在至少一个小区集合包括多个小区集合，且多个小区集合之间存在交集小区时，针对多个小区集合中每个第一小区集合确定参考小区时，就可能确定到相同的参考小区。那么就需要在这个相同的参考小区上确定用于调度多个小区的下行控制信息调度存在交集为该相同的参考小区的每个第一小区集合中小区时，所占的盲检资源。虽然有利于简化配置逻辑，但是对于相同的参考小区而言确定负担较大。
因此，在考虑小区确定负担角度，本实施例在至少一个小区集合包括多个小区集合，且多个小区集合之间存在交集小区时，可以在每个第一小区集合中确定不同的 参考小区，从而避免导致某一个参考小区的确定负担过大。
例如，对于多个小区集合：
首先，可以定义小区集合的排序方式(可以称作优先级)，例如按照小区集合的标识(id)从小到大对小区集合进行排序，或者按照小区集合的标识从大到小对小区集合进行排序，或者按照为小区集合中一个或多个小区配置的DCI所占盲检资源从大到小进行排序，或者按照为小区集合中一个或多个小区配置的DCI所占盲检资源从小到大进行排序。以下主要以按照小区集合的标识从小到大对小区集合进行排序为例进行描述。
其次，对于排序后的集合n(标识为n)，确定集合n所包含的小区，以及确定所有标识小于n的集合m(可以是一个或多个小区)所对应的参考小区，其中，可以在参考小区上确定所述MC DCI调度集合m中多个小区时，用于调度多个小区的下行控制信息所占的盲检资源。
然后，确定小区集合n对应的第二小区集合，其中，若所述集合m中的参考小区属于小区集合n，则重新确定第二小区集合，且第二小区集合不包括所述参考小区，也即，第二小区集合等于集合n所包含的所有小区排除掉所述属于集合n的参考小区(可以是被确定为集合m中的参考小区)之后的小区范围。
最后，在第二小区集合包含的小区中，确定参考小区(可以参考前述实施例)，确定的参考小区用于确定用于调度多个小区的下行控制信息在调度集合n中的多个小区时，用于调度多个小区的下行控制信息所占的盲检资源。
以基于小区id号确定参考小区为例，上述过程通过伪代码标识如下：
确定第一小区集合索引γ(j)，其中,所述γ(j)随着j(j＝0,1,2,…)的增加而逐渐增加；
Initialγ(0)，定义参考小区对应集合
Figure PCTCN2022130445-appb-000003
While j≤N(N为MC DCI对应的至少一个小区集合中集合的数量)
1确定集合γ(j)对应的所有小区中的最小小区标识n j；
If
Figure PCTCN2022130445-appb-000004
确定小区n j为确定MC DCI在调度集合γ(j)中多个小区是所占盲检资源的参考小区；
Break
θ＝θ∪n j
else；
γ(j)＝γ(j)\n j；
Return 1
j＝j+1.
以三个第一小区集合为例，例如第一小区集合包括set#1为{Cell#1、Cell#2、Cell#3}，set#2为{Cell#1、Cell#2、Cell#4}，set#3为{Cell#3、Cell#4、Cell#5}。按照小区集合的标识从小到大对小区集合进行排序为set#1、set#2、set#3。例如确定参考小区的方式为确定第一小区集合中小区标识最小的小区为参考小区。
首先在set#1(也即γ(1)对应小区集合)中确定参考小区，以第一小区集合内cell id最小对应的小区为例，例如确定set#1中的参考小区为Cell#1，则Cell#1属于集合θ；
然后在set#2(也即γ(2)对应小区集合)中确定参考小区，由于set#2内的Cell#1属于集合θ，那么将set#2重新定义为排除掉Cell#1后的其他所有剩余小区的集合，即，set#2重新定义为{Cell#2、Cell#4}。在set#2中选择小区标识最小的小区Cell#2，且Cell#2不属于集合θ，那么将Cell#2作为set#2中的参考小区，重新定义确集合θ，使得Cell#2属于集合θ；
接下来在set#3(也即γ(3)对应小区集合)中确定参考小区，考虑到set#3内不包含属于集合θ的小区，则确定set#3内cell id最小对应的小区为Cell#3，由于Cell#3不属于集合θ，那么Cell#3可以作为set#3中的参考小区，重新定义确集合θ，使得Cell#2属于集合θ。
据此，可以针对上述三个第一小区集合分别确定每个第一小区集合中的参考小区，并且能够保证每个第一小区集合中的参考小区不同。
下面通过几个实施例，对确定用于调度多个小区的下行控制信息对应的至少一个小区集合的方式进行示例性说明。
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对应的至少一个小区集合包括：
确定多个小区(例如用于调度多个小区的下行控制信息所能调度的小区)中每个小区的配置参数；
确定具有相同配置参数的小区属于用于调度多个小区的下行控制信息对应的一个小区集合。
例如以4个小区Cell#1、Cell#2、Cell#3、Cell#4，配置参数包括载波指示域(Carrier Indicator Field，CIF)为例，可以确定为这4个小区中每个小区配置的CIF(例如根据无线资源控制RRC信令确定)。例如为Cell#1配置的CIF为01，为Cell#2配置的CIF为01，为Cell#3配置的CIF为02，为Cell#4配置的CIF为02，那么可以确定Cell#1和Cell#2具有相同的CIF，Cell#3和Cell#4具有相同的CIF，从而将Cell#1和Cell#2划分为一个用于调度多个小区的下行控制信息对应的小区集合{Cell#1、Cell#2}，将Cell#3和Cell#4划分为另一个用于调度多个小区的下行控制信息对应的小区集合{Cell#3、Cell#4}。
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对应的至少一个小区集合包括：在第一小区接收网络设备发送的指示信息，其中，在多个所述第一小区发送的指示信息用于指示多个小区组；确定所述第一小区在所述多个小区组中所属的目标小区组，以及所述目标小区组所属的小区组集合；确定所述小区组集合对应的小区集合。
在一个实施例中，网络设备可以在多个第一小区向终端发送指示信息，其中，所述指示信息可以指示发送指示信息所在的第一小区对应的载波指示域CIF的值与调度小区标识之间的关联关系，网络设备可以根据每个第一小区对应的关联关系，确定多个小区组。其中，所述关联关系具体可以是调度小区内载波指示域(cif-InScheduingCell)的值与调度小区标识之间的关联关系。
其中，关联关系的作用在前文终端侧对应实施例中已有描述，此处不再赘述。而网络设备确定多个小区组的方式，与终端确定多个小区的方式是相对的，网络设备在发送指示信息之前就可以确定多个小区组，并通过指示信息指示给终端，而终端在接收到指示信息之后才能确定多个小区，并且网络设备确定用于调度多个小区的下行控制信息对应的至少一个小区集合的方式也与终端侧实施例是相对应的，此处也不赘述了。
与前述的小区确定方法的实施例相对应，本公开还提供了小区确定装置的实施 例。
图10是根据本公开的实施例示出的一种小区确定装置的示意框图。本实施例所示的小区确定装置可以为终端，或者为终端中的模块构成的装置，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。
