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：根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区；确定所述用于调度多个小区的下行控制信息所调度的至少一个第一小区；根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。
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：根据预定义规则确定或通过指示信令向终端指示，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区；确定所述用于调度多个小区的下行控制信息所调度的至少一个第一小区；根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。
根据本公开实施例的第三方面，提出一种小区确定装置，所述装置包括：处理 模块，被配置为根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区；确定所述用于调度多个小区的下行控制信息所调度的至少一个第一小区；根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。
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，被配置为根据预定义规则确定或通过指示信令向终端指示，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区；确定所述用于调度多个小区的下行控制信息所调度的至少一个第一小区；根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。
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指定的小区确定方法。
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指定的小区确定方法。
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。
根据本公开实施例的第九方面，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，实现上述由网络设备指定的小区确定方法。
根据本公开的实施例，终端可以根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区。终端还可以确定用于调度多个小区的下行控制信息所调度的至少一个第一小区，也即用于调度多个小区的下行控制信息实际调度的小区。进而可以根据MD-DCI实际调度的第一小区与 用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。据此，即使在用于调度多个小区的下行控制信息实际上所调度的小区与用于调度多个小区的下行控制信息中信息域能够应用小区不同的情况下，终端也能合理地确定用于调度多个小区的下行控制信息中信息域具体应用的小区，避免基于MD-DCI执行动作出现问题。

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，根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区；
在步骤S102中，确定所述用于调度多个小区的下行控制信息所调度的至少一个第一小区；
在步骤S103中，根据所述至少一个第一小区与所述用于调度多个小区的下行 控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。
需要说明的是，在本公开的实施例中，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区，可以是在接收到用于调度多个小区的下行控制信息之前，根据预定义规则或网络设备的指示信令确定的。而用于调度多个小区的下行控制信息所调度的至少一个第一小区，可以是在接收到用于调度多个小区的下行控制信息时确定的本次对收到的用于调度多个小区的下行控制信息实际调度的至少一个第一小区。确定的所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区，则是用于调度多个小区的下行控制信息中至少一个信息域实际应用的小区。
由于用于调度多个小区的下行控制信息至少一个信息域能够应用的小区与用于调度多个小区的下行控制信息所调度的至少一个第一小区之间可以存在多种情况，例如全部相同、全部不同、部分相同等，那么针对每种情况，需要合理地确定用于调度多个小区的下行控制信息中至少一个信息域实际应用的小区。
其中，对于用于调度多个小区的下行控制信息至少一个信息域能够应用的小区与用于调度多个小区的下行控制信息所调度的至少一个第一小区全部相同的情况，可以确定用于调度多个小区的下行控制信息所调度的至少一个第一小区就是用于调度多个小区的下行控制信息中至少一个信息域实际应用的小区。
而对于用于调度多个小区的下行控制信息至少一个信息域能够应用的小区与用于调度多个小区的下行控制信息所调度的至少一个第一小区全部不同或部分相同的情况，确定用于调度多个小区的下行控制信息中至少一个信息域实际应用的小区的过程则相对复杂，具体在后续实施例中进行说明。
其中，关于每次接收到的用于调度多个小区的下行控制信息实际所调度的至少一个第一小区，确定方式可以根据需要进行设置，例如可以由网络设备指示，也可以基于预定义规则确定，本公开不作限制。
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。
在一个实施例中，用于调度多个小区的下行控制信息可以包括多个信息域(field)，在通过用于调度多个小区的下行控制信息调度小区时，用于调度多个小区的下行控制信息中的信息域可以应用于被调度的小区，终端可以根据信息域所指示的信息确定信息域所应用的被调度小区的信息或信息域所应用的被调度小区上执行操作。例如以用于调度多个小区的下行控制信息中的带宽部分(BandWidth Part，BWP)信息域为例，例如确定BWP信息域应用于小区Cell#1，那么终端可以根据BWP信息域所指示的信息在Cell#1上执行BWP切换操作。
由于网络环境的需要，对用于调度多个小区的下行控制信息中的信息域能够应用的小区可以进行限制。根据本公开的实施例，终端可以根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中的至少一个信息域能够应用的小区。
而用于调度多个小区的下行控制信息中可以包含多个信息域，多个信息域中只有一部分信息域是应用于所有被调度小区的，另一部分信息域(例如Type1类型的信息域)考虑到调度灵活性和MC DCI信令开销，可能只需要应用于部分被调度小区，因此，如何确定这另一部分信息域实际应用的小区，是亟待解决的问题。
根据本公开的实施例，终端可以根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区。终端还可以确定用于调度多个小区的下行控制信息所调度的至少一个第一小区，也即用于调度多个小区的下行控制信息实际调度的小区。进而可以根据MD-DCI实际调度的第一小区与用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。据此，即使在用于调度多个小区的下行控制信息实际上所调度的小区与用于调度多个小区的下行控制信息中至少一个信息域能够应用小区不同的情况下，终端也能合理地确定用于调度多个小区的下行控制信息中至少一个信息域具体应用的小区，避免基于MD-DCI执行动作出现问题。
其中，所述用于调度多个小区的下行控制信息中至少一个信息域，并不应用于所有被调度小区，而只应用于部分被调度小区，例如所述用于调度多个小区的下行控制信息中至少一个信息域可以是用于调度多个小区的下行控制信息中Type1类型的信息域，也可以是其他类型的信息域，具体可以根据需要选择，本公开并不限制。
在一个实施例中，所述指示信令包括以下至少之一：
无线资源控制(Radio Resource Control，RRC)层信令；
媒体接入控制层信令，例如媒体接入控制层控制元素(Media Access Control Control Element，MAC CE)；
物理层信令，例如下行控制信息(可以是传统DCI，也可以是用于调度多个小区的下行控制信息)。
在一个实施例中，所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区包括以下至少之一：
所述用于调度多个小区的下行控制信息中至少一个信息域能够应用于至少一个第二小区，例如能够应用于用于调度多个小区的下行控制信息能够调度的小区中的部分小区(部分小区属于第二小区)；
所述用于调度多个小区的下行控制信息中至少一个信息域不能应用于任何小区，例如不能应用于用于调度多个小区的下行控制信息能够调度的小区中的任何小区。
其中，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区，可以理解为小区的集合。在用于调度多个小区的下行控制信息中至少一个信息域不能应用于任何小区时，该集合为空集；在用于调度多个小区的下行控制信息中至少一个信息域能够应用于至少一个第二小区时，该集合包含的元素为至少一个第二小区。
在一个实施例中，在用于调度多个小区的下行控制信息实际调度的第一小区，与用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间没有交集时，那么这种情可以称作错误情况(error case)，终端可以放弃解析所述用于调度多个小区的下行控制信息，或者，终端可以继续解析所述用于调度多个小区的下行控制信息，但所述用于调度多个小区的下行控制信息至少一个信息域不应用于任何小区，有利于节约终端的资源。
在一个实施例中，在用于调度多个小区的下行控制信息中至少一个信息域能够 应用的小区为用于调度多个小区的下行控制信息中至少一个信息域能够应用于至少一个第二小区时，用于调度多个小区的下行控制信息实际调度的第一小区与第二小区之间可能存在交集，也可能不存在交集，具体情况在后续实施例中进行详细说明。
以下实施例主要在用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区为用于调度多个小区的下行控制信息中至少一个信息域能够应用于至少一个第二小区，对本公开的技术方案进行示例性说明。
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，所述根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区包括：
在步骤S201中，根据预定义规则或网络设备的指示信令，确定所述至少一个信息域中每个信息域分别能够应用的至少一个第二小区。
在一个实施例中，所述用于调度多个小区的下行控制信息中的至少一个信息域，可以是多个信息域，多个信息域中每个信息域能够应用的小区可以有所不同，例如部分不同，或者全部不同。根据本实施例，终端可以根据预定义规则或网络设备的指示信令，确定每个信息域分别能够应用的第二小区。
例如对于两个信息域field#1和field#2，可以确定信息域field#1能够应用于小区Cell#1和Cell#2，确定field#2能够应用于Cell#2和Cell#3。
图3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3所示，所述根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区包括：
在步骤S301中，根据预定义规则或网络设备的指示信令，确定所述至少一个信息域能够联合应用的至少一个第二小区。
在一个实施例中，所述用于调度多个小区的下行控制信息中的至少一个信息域，可以是多个信息域，多个信息域中每个信息域能够应用的小区可以相同。根据本实施例，终端可以根据预定义规则或网络设备的指示信令，确定多个信息域能够联合应用的第二小区。
例如对于两个信息域field#1和field#2，可以确定信息域field#1和field#2能联合应用于小区Cell#1和Cell#2，其中，field#1能够应用于小区Cell#1和Cell#2，field#2也能够应用于小区Cell#1和Cell#2。
在一个实施例中，所述预定义规则包括以下至少之一：
确定标识为预定义标识的小区为所述至少一个第二小区；
在按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区或所述至少一个第一小区进行排序后，预定义次序的小区为所述至少一个第二小区。
在一个实施例中，预定义规则可以规定标识(例如小区ID)为预定义标识的小区为第二小区，那么终端可以确定具有预定义标识的小区为第二小区。
例如预定义标识为1和3，那么可以确定Cell#1(小区ID为1)和Cell#3(小区ID为3)的两个小区为第二小区。进而可以根据第二小区与第一小区之间的关系确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区，具体在后续实施例中进行说明。
在一个实施例中，预定义规则可以规定按照预定义顺序对小区进行排序后，预定义次序的小区为第二小区，进行排序的小区包括但不限于用于调度多个小区的下行控制信息能够调度的小区、至少一个第一小区。那么终端可以在排序后的小区中，确定预定义次序的小区为第二小区。
例如预定义次序为1和3，那么可以确定在按照预定义排序后的小区中，序号为1和序号为3的小区为第二小区。进而可以根据第二小区与第一小区之间的关系确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区，具体在后续实施例中进行说明。
需要说明的是，预定义顺序并不限于上述实施例中的顺序，例如还可以是小区标识从大到小的顺序，或者小区标识从小到大的顺序等。
在一个实施例中，根据网络设备的指示信令确定用于调度多个小区的下行控制信息中至少一个信息域能够应用的至少一个第二小区包括以下至少之一：
确定所述指示信令所指示的标识对应的小区为所述至少一个第二小区；
在按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区进行排序后，确定所述指示信令所指示的序号对应的小区为所述至少一个第二小区。
在一个实施例中，网络设备可以通过指示信令携带标识指示给终端，终端可以确定指示信令所指示的标识对应的小区为第二小区。其中，网络设备所指示的标识，可以是用于调度多个小区的下行控制信息能够调度的小区中小区的标识。
例如网络设备通过指示信令指示的标识为1和3，那么终端可以确定Cell#1(小区ID为1)和Cell#3(小区ID为3)的两个小区为第二小区。
在一个实施例中，网络设备可以通过指示信令携带序号指示给终端，终端可以在按照预定义顺序排序的小区中确定指示信令所指示的序号对应的小区为第二小区，进行排序的小区包括但不限于用于调度多个小区的下行控制信息能够调度的小区、至少一个第一小区。
以对4个小区Cell#1、Cell#2、Cell#3和Cell#4排序为例，排序结果为Cell#2、Cell#4、Cell#1和Cell#3，若网络设备指示的序号为1和3，可以确定排在第1的Cell#2和排在第3的Cell#1为第二小区；若网络设备指示的序号为3和5，由于排序中并不存在排在第5的小区，所以只将排在第3的Cell#1确定为第二小区；若网络设备指示的序号为5，由于排序中并不存在排在第5的小区，那么可以确定不存在第二小区，或者描述第二小区为空集，在这种情况下所述用于调度多个小区的下行控制信息中的至少一个信息域不能应用于任何小区，若是针对至少一个第一小区进行的排序，那么可以确定所述用于调度多个小区的下行控制信息中的至少一个信息域不能应用于任何小区。
需要说明的是，预定义顺序并不限于上述实施例中的顺序，例如还可以是小区标识从大到小的顺序，或者小区标识从小到大的顺序等。
例如，以小区标识从小到大的顺序进行排序为例，那么对于小区Cell#5、Cell#7、Cell#3、Cell#2，排序结果为Cell#2、Cell#3、Cell#5、Cell#7。序号与小区之间的对应关系可以如下表1所示：
序号 小区
1 Cell#2
2 Cell#3
3 Cell#5
4 Cell#7
表1
根据表1，在接收到的指示信令所指示的序号为2和4时，可以确定序号2对应的Cell#3和序号4对应的Cell#7为第二小区。
应当理解的是，表1中的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1中任何其他元素值。因此本领域内技术人员可以理解，该表1中的每一个元素的取值都是一个独立的实施例
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，所述根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区包括：
在步骤S401中，在所述至少一个第一小区为所述至少一个第二小区的子集时，确定所述信息域应用于所述至少一个第一小区，或者，确定所述信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
在一个实施例中，在至少一个第一小区为至少一个第二小区的子集时，也即用于调度多个小区的下行控制信息所调度的第一小区都属于用于调度多个小区的下行控制信息中的至少一个信息域能够应用的第二小区，那么可以确定用于调度多个小区的下行控制信息中的至少一个信息域应用于至少一个第一小区，或者，确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
以用于调度多个小区的下行控制信息中的BWP信息域为例。
例如确定预定义规则规定或网络设备指示的标识(例如小区标识)对应的小区为所述至少一个第二小区。BWP信息域能够应用的第二小区为小区Cell#1(小区标识为1)和小区Cell#2(小区标识为1)，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1。可以确定{Cell#1}为{Cell#1、Cell#2}的子集，那么可以确定BWP信息域应用于Cell#1，或者，确定BWP信息域不应用于任何小区，或者，放弃解析本次接收到的用于调度多个小区的下行控制信息。
例如按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区进行排序后，确定预定义次序或序号对应的小区为所述至少一个第二小区。BWP信息域能够应用的第二小区为序号1和序号2对应的小区，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1，按照预定义顺序排序后为Cell#1，其中仅存在排序第1的小区Cell#1，并不存在排在第2的小区，可以确定第一小区的 集合{序号1对应的小区}为第二小区的集合{序号1对应的小区、序号2对应的小区}的子集，进而确定BWP信息域应用于序号1对应的小区Cell#1，或者，确定BWP信息域不应用于任何小区，或者，放弃解析本次接收到的用于调度多个小区的下行控制信息。
在一个实施例中，在所述至少一个第二小区为所述至少一个第一小区的子集时，确定所述信息域应用于所述至少一个第二小区，或者，确定所述信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
在一个实施例中，在至少一个第二小区为至少一个第一小区的子集时，也即用于调度多个小区的下行控制信息中的至少一个信息域能够应用的第二小区都属于用于调度多个小区的下行控制信息所调度的第一小区，那么可以确定用于调度多个小区的下行控制信息中的至少一个信息域应用于至少一个第二小区，或者，确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
以用于调度多个小区的下行控制信息中的BWP信息域为例。
例如确定预定义规则规定或网络设备指示的标识(例如小区标识)对应的小区为所述至少一个第二小区。BWP信息域能够应用的第二小区为小区Cell#1，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1和Cell#2。可以确定{Cell#1}为{Cell#1、Cell#2}的子集，那么可以确定BWP信息域应用于Cell#1，或者，确定BWP信息域不应用于任何小区，或者，放弃解析本次接收到的用于调度多个小区的下行控制信息。
例如按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区进行排序后，确定预定义次序或序号对应的小区为所述至少一个第二小区。BWP信息域能够应用的第二小区为序号2对应的小区，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1和Cell#2，按照预定义顺序(例如标识从小到大)排序后为Cell#1、Cell#2，其中不仅包含序号为2的小区，还包含序号为1的小区，可以确定第二小区的集合{序号2对应的小区}为第一小区的集合{序号1对应的小区、序号2对应的小区}的子集，进而确定BWP信息域应用于序号2对应的小区Cell#2，或者，确定BWP信息域不应用于任何小区，或者，放弃解析本次接收到的用于调度多个小区的下行控制信息。
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，所述根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区包括：
在步骤S501中，在所述至少一个第一小区与所述至少一个第二小区之间存在交集，且所述至少一个第一小区不是所述至少一个第二小区的子集时，确定所述信息域应用于所述交集中的小区，或者，确定所述信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
在一个实施例中，在所述至少一个第一小区与所述至少一个第二小区之间存在交集，且所述至少一个第一小区不是所述至少一个第二小区的子集时，也即用于调度多个小区的下行控制信息所调度的第一小区中部分小区属于用于调度多个小区的下行控制信息中的至少一个信息域能够应用的第二小区，那么至少一个第一小区和至少一个第二小区之间一部分小区相同，另一部分小区则不同。
对此情况，可以采取三种方式，第一种是主要考虑到冲突的存在，那么这种情况可以被视作错误情况(error case)，终端执行的动作为放弃解析用于调度多个小区的下行控制信息；第二种是主要考虑没有冲突的部分，也即至少一个第一小区与至少一个第二小区之间的交集，那么可以确定所述用于调度多个小区的下行控制信息中至少一个信息域应用于交集中的小区；第三种是确定所述信息域不应用于任何小区，这种方式仍需要解析用于调度多个小区的下行控制信息，只不过用于调度多个小区的下行控制信息中的所述信息域(也即所述用于调度多个小区的下行控制信息中至少一个信息域)不应用于任何小区，用于调度多个小区的下行控制信息中其他信息域仍然正常应用于所应应用的小区。
以用于调度多个小区的下行控制信息中的BWP信息域为例。
例如确定预定义规则规定或网络设备指示的标识(例如小区标识)对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为小区Cell#1和小区Cell#2，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1和Cell#3。可以确定{Cell#1、Cell#3}与{Cell#1、Cell#2}之间存在交集{Cell#1}，对此情况，如果预定义规则规定或者网络设备指示用于调度多个小区的下行控制信息中至少一个信息域应用于交集中的小区，那么可以确定BWP信息域应用于交集{Cell#1}中的小区Cell#1；如果预定义规则规定或者网络设备指示这种情况为error case，那么终 端可以将此情况视作error case，放弃解析用于调度多个小区的下行控制信息；或者，可以确定BWP信息域不应用于任何小区，但是BWP信息域以外的信息域，仍然正常应用于所应应用的小区，例如频域资源分配(Frequency Domain Resource Allocation，FDRA)域仍然正常应用于FDRA域所应应用的小区。
例如按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区进行排序后，确定预定义次序或序号对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为序号1和序号3对应的小区，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1和Cell#3，按照预定义顺序排序后为Cell#1、Cell#3，其中仅存在排序第1和排在第2的小区，不存在排在第3的小区，可以确定第二小区为Cell#1，第二小区的集合{Cell#1}与第一小区的集合{Cell#1、Cell#2}之间存在交集{Cell#1}，且{Cell#1、Cell#2}不是{Cell#1}的子集。对此情况，如果预定义规则规定或者网络设备指示用于调度多个小区的下行控制信息中至少一个信息域应用于交集中的小区，那么可以确定BWP信息域应用于交集{Cell#1}中的小区Cell#1；如果预定义规则规定或者网络设备指示这种情况为error case，那么终端可以将此情况视作error case，放弃解析用于调度多个小区的下行控制信息；或者，可以确定BWP信息域不应用于任何小区，但是BWP信息域以外的信息域，仍然正常应用于所应应用的小区，例如频域资源分配FDRA域仍然正常应用于FDRA域所应应用的小区。
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，所述根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区包括：
在步骤S601中，在所述至少一个第一小区与所述至少一个第二小区之间不存在交集时，确定所述信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
在一个实施例中，在所述至少一个第一小区与所述至少一个第二小区之间不存在交集时，用于调度多个小区的下行控制信息所调度的第一小区与属于用于调度多个小区的下行控制信息中的至少一个信息域能够应用的第二小区之间没有相同的小区，那么用于调度多个小区的下行控制信息中的至少一个信息域，不应用于任何小区。
因此，对于这种情况，可以确定用于调度多个小区的下行控制信息中的至少一 个信息域不应用于任何小区，或者，将这种情况视作error case，终端放弃解析用于调度多个小区的下行控制信息。
需要说明的是，终端确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于第一小区，与放弃解析用于调度多个小区的下行控制信息是不同的。终端确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，是指对于用于调度多个小区的下行控制信息中的至少一个信息域，终端不将其应用于任何小区，但是对于用于调度多个小区的下行控制信息中的至少一个信息域以外的信息域，仍然可以正常应用于用于调度多个小区的下行控制信息所调度的小区，而并不会放弃解析整个用于调度多个小区的下行控制信息。
以用于调度多个小区的下行控制信息中的BWP信息域为例。
例如确定预定义规则规定或网络设备指示的标识(例如小区标识)对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为小区Cell#1和小区Cell#3，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#2和Cell#4。可以确定{Cell#1、Cell#3}与{Cell#2、Cell#4}之间不存在交集，对此情况，如果预定义规则规定或者网络设备指示所述信息域不应用于所述第一小区，那么可以确定BWP信息域应不用于任何小区；如果预定义规则规定或者网络设备指示这种情况为error case，那么终端可以将此情况视作error case，放弃解析用于调度多个小区的下行控制信息。
例如按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区进行排序后，确定预定义次序或序号对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为序号3和序号4对应的小区，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#2和Cell#4，按照预定义顺序排序后为Cell#2、Cell#4，其中仅存在排序第1和排在第2的小区，不存在排在第3和第4的小区，可以确定第二小区的集合为空集与第一小区的集合{Cell#2、Cell#4}之间不存在交集。对此情况，如果预定义规则规定或者网络设备指示所述信息域不应用于所述第一小区，那么可以确定BWP信息域应不用于任何小区如果预定义规则规定或者网络设备指示这种情况为error case，那么终端可以将此情况视作error case，放弃解析用于调度多个小区的下行控制信息。
在一个实施例中，所述终端不期待用于调度多个小区的下行控制信息所调度的至少一个第一小区与所述至少一个第二小区之间不存在交集。
由于第一小区与第二小区之间不存在交集时，终端会确定所述用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，或者放弃解析所述用于调度多个小区的下行控制信息，这在一定程度上存在通信资源的浪费。因此，终端可以不期待用于调度多个小区的下行控制信息所调度的至少一个第一小区与所述至少一个第二小区之间不存在交集，相对应地，网络设备在向终端发送用于调度多个小区的下行控制信息时，可以设置通过用于调度多个小区的下行控制信息所调度的至少一个第一小区与至少一个第二小区之间存在交集，据此，有利于避免通信资源的浪费。
图7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7所示，所述小区确定方法可以包括以下步骤：
在步骤S701中，根据预定义规则确定或通过指示信令向终端指示，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区；
在步骤S702中，确定所述用于调度多个小区的下行控制信息所调度的至少一个第一小区；
在步骤S703中，根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。
需要说明的是，在本公开的实施例中，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区，可以是在接收到用于调度多个小区的下行控制信息之前，根据预定义规则或网络设备的指示信令确定的。而用于调度多个小区的下行控制信息所调度的至少一个第一小区，可以是在接收到用于调度多个小区的下行控制信息时确定的本次对收到的用于调度多个小区的下行控制信息实际调度的至少一个第一小区。确定的所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区，则是用于调度多个小区的下行控制信息中至少一个信息域实际应用的小区。
由于用于调度多个小区的下行控制信息至少一个信息域能够应用的小区与用于调度多个小区的下行控制信息所调度的至少一个第一小区之间可以存在多种情况，例如全部相同、全部不同、部分相同等，那么针对每种情况，需要合理地确定用于调 度多个小区的下行控制信息中至少一个信息域实际应用的小区。
其中，对于用于调度多个小区的下行控制信息至少一个信息域能够应用的小区与用于调度多个小区的下行控制信息所调度的至少一个第一小区全部相同的情况，可以确定用于调度多个小区的下行控制信息所调度的至少一个第一小区就是用于调度多个小区的下行控制信息中至少一个信息域实际应用的小区。
而对于用于调度多个小区的下行控制信息至少一个信息域能够应用的小区与用于调度多个小区的下行控制信息所调度的至少一个第一小区全部不同或部分相同的情况，确定用于调度多个小区的下行控制信息中至少一个信息域实际应用的小区的过程则相对复杂，具体在后续实施例中进行说明。
其中，关于每次接收到的用于调度多个小区的下行控制信息实际所调度的至少一个第一小区，确定方式可以根据需要进行设置，例如可以由网络设备指示，也可以基于预定义规则确定，本公开不作限制。
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。
在一个实施例中，用于调度多个小区的下行控制信息可以包括多个信息域(field)，在通过用于调度多个小区的下行控制信息调度小区时，用于调度多个小区的下行控制信息中的信息域可以应用于被调度的小区，终端可以根据信息域所指示的信息确定信息域所应用的被调度小区的信息或信息域所应用的被调度小区上执行操作。例如以用于调度多个小区的下行控制信息中的带宽部分BWP信息域为例，例如确定BWP信息域应用于小区Cell#1，那么终端可以根据BWP信息域所指示的信息在Cell#1上执行BWP切换操作。
由于网络环境的需要，对用于调度多个小区的下行控制信息中的信息域能够应用的小区可以进行限制。根据本公开的实施例，终端可以根据预定义规则或网络设备的指示信令，确定用于调度多个小区的下行控制信息中的至少一个信息域能够应用的小区。
而用于调度多个小区的下行控制信息中可以包含多个信息域，多个信息域中只有一部分信息域是应用于所有被调度小区的，另一部分信息域(例如Type1类型的信息域)考虑到调度灵活性和MC DCI信令开销，可能只需要应用于部分被调度小区，因此，如何确定这另一部分信息域实际应用的小区，是亟待解决的问题。
根据本公开的实施例，网络可以根据预定义规则确定或通过指示信令向终端指示，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区。并在向终端能发送用于调度多个小区的下行控制信息时，还可以确定用于调度多个小区的下行控制信息所调度的至少一个第一小区，也即用于调度多个小区的下行控制信息实际调度的小区。进而可以根据MD-DCI实际调度的第一小区与用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定用于调度多个小区的下行控制信息中至少一个信息域所应用的小区。据此，即使在用于调度多个小区的下行控制信息实际上所调度的小区与用于调度多个小区的下行控制信息中至少一个信息域能够应用小区不同的情况下，也能合理地确定用于调度多个小区的下行控制信息中至少一个信息域具体应用的小区。
其中，所述用于调度多个小区的下行控制信息中至少一个信息域，并不应用于所有被调度小区，而只应用于部分被调度小区，例如所述用于调度多个小区的下行控制信息中至少一个信息域可以是用于调度多个小区的下行控制信息中Type1-C类型的信息域，也可以是其他类型的信息域，具体可以根据需要选择，本公开并不限制。
在一个实施例中，所述指示信令包括以下至少之一：
无线资源控制层信令，也即RRC信令；
媒体接入控制层信令，例如MAC CE；
物理层信令，例如DCI。
在一个实施例中，所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区包括以下至少之一：
所述用于调度多个小区的下行控制信息中至少一个信息域能够应用于至少一 个第二小区，例如能够应用于用于调度多个小区的下行控制信息能够调度的小区中的部分小区(部分小区属于第二小区)；
所述用于调度多个小区的下行控制信息中至少一个信息域不能应用于任何小区，例如不能应用于用于调度多个小区的下行控制信息能够调度的小区中的任何小区。
其中，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区，可以理解为小区的集合。在用于调度多个小区的下行控制信息中至少一个信息域不能应用于任何小区时，该集合为空集；在用于调度多个小区的下行控制信息中至少一个信息域能够应用于至少一个第二小区时，该集合包含的元素为至少一个第二小区。
在一个实施例中，在用于调度多个小区的下行控制信息实际调度的第一小区，与用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间没有交集时，那么这种情可以称作错误情况(error case)，终端可以放弃解析所述用于调度多个小区的下行控制信息，或者，终端可以继续解析所述用于调度多个小区的下行控制信息，但所述用于调度多个小区的下行控制信息至少一个信息域不应用于任何小区，有利于节约终端的资源。
在一个实施例中，在用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区为用于调度多个小区的下行控制信息中至少一个信息域能够应用于至少一个第二小区时，用于调度多个小区的下行控制信息实际调度的第一小区与第二小区之间可能存在交集，也可能不存在交集，具体情况在后续实施例中进行详细说明。
以下实施例主要在用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区为用于调度多个小区的下行控制信息中至少一个信息域能够应用于至少一个第二小区，对本公开的技术方案进行示例性说明。
图8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8所示，所述根据预定义规则确定或通过指示信令向终端指示，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区包括：
在步骤S801中，根据预定义规则确定或通过指示信令向终端指示，所述至少一个信息域中每个信息域分别能够应用的至少一个第二小区。
在一个实施例中，所述用于调度多个小区的下行控制信息中的至少一个信息域，可以是多个信息域，多个信息域中每个信息域能够应用的小区可以有所不同，例如部分不同，或者全部不同。根据本实施例，网络设备可以根据预定义规则确定或者 通过指示信令向终端指示，每个信息域分别能够应用的第二小区。
例如对于两个信息域field#1和field#2，可以确定信息域field#1能够应用于小区Cell#1和Cell#2，确定field#2能够应用于Cell#2和Cell#3。
图9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9所示，所述根据预定义规则确定或通过指示信令向终端指示，用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区包括：
在步骤S901中，根据预定义规则确定或通过指示信令向终端指示，所述至少一个信息域能够联合应用的至少一个第二小区。
在一个实施例中，所述用于调度多个小区的下行控制信息中的至少一个信息域，可以是多个信息域，多个信息域中每个信息域能够应用的小区可以相同。根据本实施例，网络设备可以根据预定义规则确定或通过指示信令向终端指示，多个信息域能够联合应用的第二小区。
例如对于两个信息域field#1和field#2，可以确定信息域field#1和field#2能联合应用于小区Cell#1和Cell#2，其中，field#1能够应用于小区Cell#1和Cell#2，field#2也能够应用于小区Cell#1和Cell#2。
在一个实施例中，所述预定义规则包括以下至少之一：
确定标识为预定义标识的小区为所述至少一个第二小区；
在按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区或所述至少一个第一小区进行排序后，预定义次序的小区为所述至少一个第二小区。
在一个实施例中，预定义规则可以规定标识(例如小区ID)为预定义标识的小区为第二小区，那么终端可以确定具有预定义标识的小区为第二小区。
例如预定义标识为1和3，那么可以确定Cell#1(小区ID为1)和Cell#3(小区ID为3)的两个小区为第二小区。进而可以根据第二小区与第一小区之间的关系确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区，具体在后续实施例中进行说明。
在一个实施例中，预定义规则可以规定按照预定义顺序对小区进行排序后，预定义次序的小区为第二小区，进行排序的小区包括但不限于用于调度多个小区的下行控制信息能够调度的小区、至少一个第一小区。那么网络设备可以在排序后的小区中， 确定预定义次序的小区为第二小区。
例如预定义次序为1和3，那么可以确定在按照预定义排序后的小区中，序号为1和序号为3的小区为第二小区。进而可以根据第二小区与第一小区之间的关系确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区，具体在后续实施例中进行说明。
需要说明的是，预定义顺序并不限于上述实施例中的顺序，例如还可以是小区标识从大到小的顺序，或者小区标识从小到大的顺序等。
在一个实施例中，通过指示信令向终端指示用于调度多个小区的下行控制信息中至少一个信息域能够应用的至少一个第二小区包括以下至少之一：
通过指示信令向终端指示标识对应的小区为所述至少一个第二小区；
通过指示信令向终端指示在按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区或所述至少一个第一小区进行排序后，所述指示信令所指示的序号对应的小区为所述至少一个第二小区。
在一个实施例中，网络设备可以通过指示信令携带标识指示给终端，终端可以确定指示信令所指示的标识对应的小区为第二小区。其中，网络设备所指示的标识，可以是用于调度多个小区的下行控制信息能够调度的小区中小区的标识。
例如网络设备通过指示信令指示的标识为1和3，那么终端可以确定Cell#1(小区ID为1)和Cell#3(小区ID为3)的两个小区为第二小区。
在一个实施例中，网络设备可以通过指示信令携带序号指示给终端，终端可以在按照预定义顺序排序的小区中确定指示信令所指示的序号对应的小区为第二小区，进行排序的小区包括但不限于用于调度多个小区的下行控制信息能够调度的小区、至少一个第一小区。
以对4个小区Cell#1、Cell#2、Cell#3和Cell#4排序为例，排序结果为Cell#2、Cell#4、Cell#1和Cell#3，若网络设备指示的序号为1和3，可以确定排在第1的Cell#2和排在第3的Cell#1为第二小区；若网络设备指示的序号为3和5，由于排序中并不存在排在第5的小区，所以只将排在第3的Cell#1确定为第二小区；若网络设备指示的序号为5，由于排序中并不存在排在第5的小区，那么可以确定不存在第二小区，或者描述第二小区为空集，在这种情况下所述用于调度多个小区的下行控制信息中的至少一个信息域不能应用于任何小区，若是针对至少一个第一小区进行的排序，那么 可以确定所述用于调度多个小区的下行控制信息中的至少一个信息域不能用于任何小区。
需要说明的是，预定义顺序并不限于上述实施例中的顺序，例如还可以是小区标识从大到小的顺序，或者小区标识从小到大的顺序等。
图10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10所示，所述根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区包括：
在步骤S1001中，在所述至少一个第一小区为所述至少一个第二小区的子集时，确定所述信息域应用于所述至少一个第一小区，或者，确定所述信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
在一个实施例中，在至少一个第一小区为至少一个第二小区的子集时，也即用于调度多个小区的下行控制信息所调度的第一小区都属于用于调度多个小区的下行控制信息中的至少一个信息域能够应用的第二小区，那么可以确定用于调度多个小区的下行控制信息中的至少一个信息域应用于至少一个第一小区，或者，确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
以用于调度多个小区的下行控制信息中的BWP信息域为例。
例如通过指示信令向终端指示标识对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为小区Cell#1和小区Cell#2，本次向终端发送的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1。可以确定{Cell#1}为{Cell#1、Cell#2}的子集，那么可以确定BWP信息域应用于Cell#1。
例如通过指示信令向终端指示在按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区或所述至少一个第一小区进行排序后，所述指示信令所指示的序号对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为序号1和序号2对应的小区，本次向终端发送的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1，按照预定义顺序排序后为Cell#1，其中仅存在排序第1的小区Cell#1，并不存在排在第2的小区，集合{序号1对应的小区}为第二小区的集合{序号1对应的小区、序号2对应的小区}的子集，进而确定BWP信息域应用于 序号1对应的小区Cell#1，或者，确定BWP信息域不应用于任何小区，或者，放弃解析本次接收到的用于调度多个小区的下行控制信息。
在一个实施例中，在所述至少一个第二小区为所述至少一个第一小区的子集时，确定所述信息域应用于所述至少一个第二小区，或者，确定所述信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
在一个实施例中，在至少一个第二小区为至少一个第一小区的子集时，也即用于调度多个小区的下行控制信息中的至少一个信息域能够应用的第二小区都属于用于调度多个小区的下行控制信息所调度的第一小区，那么可以确定用于调度多个小区的下行控制信息中的至少一个信息域应用于至少一个第二小区，或者，确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
以用于调度多个小区的下行控制信息中的BWP信息域为例。
例如通过指示信令向终端指示标识对应的小区为所述至少一个第二小区。BWP信息域能够应用的第二小区为小区Cell#1，本次接收到的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1和Cell#2。可以确定{Cell#1}为{Cell#1、Cell#2}的子集，那么可以确定BWP信息域应用于Cell#1，或者，确定BWP信息域不应用于任何小区，或者，放弃解析本次接收到的用于调度多个小区的下行控制信息。
例如通过指示信令向终端指示在按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区或所述至少一个第一小区进行排序后，所述指示信令所指示的序号对应的小区为所述至少一个第二小区。例如按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区进行排序后，确定预定义次序或序号对应的小区为所述至少一个第二小区。BWP信息域能够应用的第二小区为序号2对应的小区，本次向终端发送的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1和Cell#2，按照预定义顺序(例如标识从小到大)排序后为Cell#1、Cell#2，其中不仅包含序号为2的小区，还包含序号为1的小区，可以确定第二小区的集合{序号2对应的小区}为第一小区的集合{序号1对应的小区、序号2对应的小区}的子集，进而确定BWP信息域应用于序号2对应的小区Cell#2，或者，确定BWP信息域不应用于任何小区，或者，放弃解析本次接收到的用于调度多个小区的下行控制信息。
图11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 11所示，所述根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区包括：
在步骤S1101中，在所述至少一个第一小区与所述至少一个第二小区之间存在交集，且所述至少一个第一小区不是所述至少一个第二小区的子集时，确定所述信息域应用于所述交集中的小区，或者，确定所述信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
在一个实施例中，在所述至少一个第一小区与所述至少一个第二小区之间存在交集，且所述至少一个第一小区不是所述至少一个第二小区的子集时，也即用于调度多个小区的下行控制信息所调度的第一小区中部分小区属于用于调度多个小区的下行控制信息中的至少一个信息域能够应用的第二小区，那么至少一个第一小区和至少一个第二小区之间一部分小区相同，另一部分小区则不同。
对此情况，可以采取三种方式，第一种是主要考虑到冲突的存在，那么这种情况可以被视作错误情况(error case)，确定终端会放弃解析用于调度多个小区的下行控制信息；第二种是主要考虑没有冲突的部分，也即至少一个第一小区与至少一个第二小区之间的交集，那么可以确定所述用于调度多个小区的下行控制信息中至少一个信息域应用于交集中的小区；第三种是确定所述信息域不应用于任何小区，这种方式中终端仍需要解析用于调度多个小区的下行控制信息，只不过用于调度多个小区的下行控制信息中的所述信息域(也即所述用于调度多个小区的下行控制信息中至少一个信息域)不应用于任何小区，用于调度多个小区的下行控制信息中其他信息域仍然正常应用于所应应用的小区。
以用于调度多个小区的下行控制信息中的BWP信息域为例。
例如通过指示信令向终端指示标识对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为小区Cell#1和小区Cell#2，本次向终端发送的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1和Cell#3。可以确定{Cell#1、Cell#3}与{Cell#1、Cell#2}之间存在交集{Cell#1}，对此情况，可以确定BWP信息域应用于交集{Cell#1}中的小区Cell#1，也可以将此情况视作error case，确定终端放弃解析用于调度多个小区的下行控制信息；或者，可以确定BWP信息域不应用于任何小区，但是BWP信息域以外的信息域，仍然正常应用于所应应用的小区，例如频域资源分配FDRA域仍然正常应用于FDRA域所应应用的小区。
例如通过指示信令向终端指示在按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区或所述至少一个第一小区进行排序后，所述指示信令所指示的序号对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为序号1和序号3对应的小区，本次向终端发送的用于调度多个小区的下行控制信息所调度的第一小区为Cell#1和Cell#3，按照预定义顺序排序后为Cell#1、Cell#3，其中仅存在排序第1和排在第2的小区，不存在排在第3的小区，可以确定第二小区为Cell#1，第二小区的集合{Cell#1}与第一小区的集合{Cell#1、Cell#2}之间存在交集{Cell#1}，且{Cell#1、Cell#2}不是{Cell#1}的子集。对此情况，可以确定BWP信息域应用于交集{Cell#1}中的小区Cell#1，或者可以将此情况视作error case，确定终端放弃解析用于调度多个小区的下行控制信息；或者，可以确定BWP信息域不应用于任何小区，但是BWP信息域以外的信息域，仍然正常应用于所应应用的小区，例如频域资源分配FDRA域仍然正常应用于FDRA域所应应用的小区。
图12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12所示，所述根据所述至少一个第一小区与所述用于调度多个小区的下行控制信息中至少一个信息域能够应用的小区之间的关系，确定所述用于调度多个小区的下行控制信息中至少一个信息域所应用的小区包括：
在步骤S1201中，在所述至少一个第一小区与所述至少一个第二小区之间不存在交集时，确定所述信息域不应用于任何小区，或者，放弃解析所述用于调度多个小区的下行控制信息。
在一个实施例中，在所述至少一个第一小区与所述至少一个第二小区之间不存在交集时，用于调度多个小区的下行控制信息所调度的第一小区与属于用于调度多个小区的下行控制信息中的至少一个信息域能够应用的第二小区之间没有相同的小区，那么用于调度多个小区的下行控制信息中的至少一个信息域，不应用于任何小区。
因此，对于这种情况，可以确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，或者，将这种情况视作error case，确定终端放弃解析用于调度多个小区的下行控制信息。
需要说明的是，确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于第一小区，与确定终端放弃解析用于调度多个小区的下行控制信息是不同的。确定用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，是指对于用于调度多个小区的下行控制信息中的至少一个信息域，不将其应用于任何小区， 但是对于用于调度多个小区的下行控制信息中的至少一个信息域以外的信息域，仍然可以正常应用于用于调度多个小区的下行控制信息所调度的小区I。
以用于调度多个小区的下行控制信息中的BWP信息域为例。
例如通过指示信令向终端指示标识对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为小区Cell#1和小区Cell#3，本次向终端发送的用于调度多个小区的下行控制信息所调度的第一小区为Cell#2和Cell#4。可以确定{Cell#1、Cell#3}与{Cell#2、Cell#4}之间不存在交集，对此情况，可以确定BWP信息域应不用于任何小区，或者将此情况视作error case，确定终端放弃解析用于调度多个小区的下行控制信息。
例如通过指示信令向终端指示在按照预定义顺序对所述用于调度多个小区的下行控制信息能够调度的小区或所述至少一个第一小区进行排序后，所述指示信令所指示的序号对应的小区为所述至少一个第二小区。例如BWP信息域能够应用的第二小区为序号3和序号4对应的小区，本次向终端发送的用于调度多个小区的下行控制信息所调度的第一小区为Cell#2和Cell#4，按照预定义顺序排序后为Cell#2、Cell#4，其中仅存在排序第1和排在第2的小区，不存在排在第3和第4的小区，可以确定第二小区的集合为空集与第一小区的集合{Cell#2、Cell#4}之间不存在交集。对此情况，可以确定BWP信息域应不用于任何小区，或者将此情况视作error case，确定终端放弃解析用于调度多个小区的下行控制信息。
在一个实施例中，所述终端不期待用于调度多个小区的下行控制信息所调度的至少一个第一小区与所述至少一个第二小区之间不存在交集。
由于第一小区与第二小区之间不存在交集时，终端会确定所述用于调度多个小区的下行控制信息中的至少一个信息域不应用于任何小区，或者放弃解析所述用于调度多个小区的下行控制信息，这在一定程度上存在通信资源的浪费。因此，终端可以不期待用于调度多个小区的下行控制信息所调度的至少一个第一小区与所述至少一个第二小区之间不存在交集，相对应地，网络设备在向终端发送用于调度多个小区的下行控制信息时，可以设置通过用于调度多个小区的下行控制信息所调度的至少一个第一小区与至少一个第二小区之间存在交集，据此，有利于避免通信资源的浪费。
