Description

数据收发方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
物理下行共享信道(Physical Downlink Shared Channel,PDSCH)是无线通信系统中物理下行信道的一种，用于承载下行数据。物理上行共享信道(Physical Uplink Shared Channel,PUSCH)是无线通信系统中物理上行信道的一种，用于承载上行数据。PDSCH和PUSCH可以是通过下行控制信息(downlink control information，DCI)调度的。在目前的新无线(newradio，NR)系统中，定义了多种用于调度PDSCH或PUSCH的DCI格式(format)，不同DCI format的DCI包括的具体信息和/或大小是不一样的，以满足不同的调度需求。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
目前，无线资源控制配置载波(小区)进行自调度或跨载波调度。自调度，即一个载波上的PDSCH和/或PUSCH由该载波上发送的DCI调度；跨载波调度，即在一个载波(小区)上的PDSCH和/或PUSCH由调度另一个载波(小区)上发送的DCI调度。
目前，DCI仅支持(一次)调度一个服务小区，包括针对自调度和跨载波调度的情况。为了减轻终端设备的DCI监听负担，降低耗电量以及复杂度，NR系统将支持通过一个DCI调度多个服务小区的PDSCH和/或PUSCH，然而，目前还没有关于如何支持通过一个DCI调度多个服务小区的PDSCH和/或PUSCH的具体方案(例如如何指示/确定一个DCI调度的一个或多个服务小区等)。
针对上述问题的至少之一，本申请实施例提供一种数据收发方法以及装置。
根据本申请实施例的一个方面，提供一种数据收发装置，应用于终端设备，所述 装置包括：
第一接收单元，其在第一小区接收下行控制信息(DCI)，所述DCI用于调度所述第一小区和/或至少一个第二小区中的至少两个小区上的PDSCH和/或PUSCH；
第一收发单元，其在所述至少两个小区接收所述PDSCH和/或发送所述PUSCH。
根据本申请实施例的一个方面，提供一种数据收发装置，应用于网络设备，所述装置包括：
第一发送单元，其在第一小区发送下行控制信息(DCI)，所述DCI用于调度所述第一小区和/或至少一个第二小区中的至少两个小区上的PDSCH和/或PUSCH；
第二收发单元，其在所述至少两个小区发送所述PDSCH和/或接收所述PUSCH。
根据本申请实施例的一个方面，提供一种通信系统，所述系统包括：终端设备和/或网络设备，该终端设备包括前一方面的数据收发装置，该网络设备包括前一方面的数据收发装置。
本申请实施例的有益效果之一在于：可以支持通过一个DCI调度多个服务小区的PDSCH和/或PUSCH，进而减轻终端设备的DCI监听负担，降低耗电量以及复杂度。

目前，跨载波调度由RRC跨载波调度配置(CrossCarrierSchedulingConfig)信元配置，该信元由服务小区的服务小区配置(ServingCellConfg)承载，通过CrossCarrierSchedulingConfig配置该服务小区是由另一个服务小区跨载波调度的还是可以跨载波调度另一个服务小区。
如果该serving cell是可以跨载波调度另一个serving cell，该serving cell例如称为调度小区(scheduling cell)。如果该serving cell是由另一个serving cell跨载波调度的，该serving cell例如称为被调度小区(scheduled cell)。Scheduling cell可以承载用于调度scheduled cell的下行链路控制信息DCI。
目前，DCI仅支持调度一个服务小区，包括针对自调度和跨载波调度的情况。假设CrossCarrierSchedulingConfig配置小区C由小区A跨小区调度并且配置小区C对应的载波指示域(Carrier Indicator Field，CIF)值为1，在小区A上一个用于调度PDSCH/PUSCH的DCI中的CIF的值为1的情况下，此DCI在小区C上调度PDSCH/PUSCH。
为了减轻终端设备的DCI监听负担，降低耗电量以及复杂度，NR系统将支持通过一个DCI调度多个服务小区的PDSCH和/或PUSCH，然而，目前还没有关于如何支持通过一个DCI调度多个服务小区的PDSCH和/或PUSCH的具体方案(例如如何指示/确定一个DCI调度的一个或多个服务小区等)。
以下结合实施例进行说明。
第一方面的实施例
本申请实施例提供一种数据收发方法，从终端设备侧进行说明。
图2是本申请实施例的数据收发方法的一示意图，如图2所示，该方法包括：
201，终端设备在第一小区接收下行控制信息(DCI)，该DCI用于调度该第一小区和/或至少一个第二小区中的至少两个小区上的PDSCH和/或PUSCH；
202，终端设备在该至少两个小区接收该DCI调度的PDSCH和/或发送该DCI调度的PUSCH。
在一些实施例中，该终端设备在第一小区接收DCI，该第一小区可以调度第一小区和/或第二小区上的PDSCH和/或PUSCH。该第一小区也可以称为调度小区(schedulingcell)，该第二小区也可以称为被调度小区(scheduled cell)，但不限于此。或者该第一小区也可以调度其自身的PDSCH和/或PUSCH(self-scheduling)。该第一小区可以是主小区或辅小区，第二小区可以是主小区或辅小区，本申请实施例并不以此作为限制。
在一些实施例中，一个第二小区对应一个或多个第一小区，也就是说，多个第一小区均可以调度该一个第二小区上的PDSCH和/或PUSCH，该多个第一小区分别对应的至少一个第二小区均包括该一个第二小区。
在一些实施例中，一个小区既是第一小区，又是第二小区，也就是说，该一个小区既可以用于调度另外的至少一个第二小区上的PDSCH和/或PUSCH，又可以被另外的至少一个第一小区调度该一个小区上的PDSCH和/或PUSCH。
在一些实施例中，第一小区调度第一或第二小区也可以称为第一小区调度第一或第二小区上的PDSCH和/或PUSCH，或者DCI调度小区也可以称为DCI调度第一或第二小区上的PDSCH和/或PUSCH，或者第一小区上接收的DCI调度第一或第二小区上的PDSCH和/或PUSCH。用于调度PDSCH的DCI也可以称为下行分配(DL assignment)，用于调度PUSCH的DCI也可以称为上行授权(UL grant)。在一些实施例中，该DCI用于调度至少两个小区上的PDSCH和/或PUSCH，由此，减轻终端设备的DCI监听负担，降低耗电量以及复杂度，该至少两个小区(以下简称M个小区，M为大于或等于2的整数)是第一小区和/或至少一个(N个，N为大于或等于1的 整数)第二小区中的M个小区。也就是说，该M个小区可以都是N个第二小区中的M个小区，或者该M个小区可以是一个第一小区和N个第二小区中的M-1个小区。
以下说明第一小区和N个第二小区的范围。
在一些实施例中，该第一小区和N个第二小区可以包括主小区组或辅小区组或同一PUCCH组中的全部或部分小区(集合1)，或者，该第一小区和该至少一个第二小区包括能够(可以)被该第一小区调度的小区(集合2)，或能够(可以)被第一小区同时调度的小区(集合3)，或能够(可以)被该DCI调度的小区(集合4)，该第一小区和N个第二小区也可以称为捆绑小区(bundled cell)或者上述DCI调度的至少两个小区称为捆绑小区，不限于此。
在一些实施例中，该第一小区和/或至少一个第二小区可以包括至少一个(P个)子小区组，不同子小区组中的小区不能被(该第一小区上的)同一个DCI调度。也就是说同一个DCI在调度M个小区时，该M个小区属于同一子小区组中，或者说，该M个小区中不存在分布在不同子小区组内的至少两个小区。
在一些实施例中，子小区组是集合1或集合2或集合3或集合4的子集，但本申请实施例并不以此作为限制，例如在该第一小区和N个第二小区为集合1时，子小区组可以是集合2或3或4，或者是集合2或集合3或集合4的子集，此处不再一一举例。另外，不同场景下涉及到的子小区组的划分方式(小区范围)相同或不同，后述详细说明。
在一些实施例中，子小区组合是指集合1或集合2或集合3或集合4的子集，例如集合1或2或3或4中可以由同一DCI调度的小区作为一个子小区组合，子小区组或子小区组合中可以包括一个或多个小区，不同的子小区组有交集或没有交集，不同的子小区组合有交集或没有交集，子小区组和子小区组合相同或不同。
图3A和图3B是该第一小区和N个第二小区的分布示意图，如图3A和3B所示，不同小区(载波)可以在相同的频率范围(频带)内，也可以在不同的频率范围(频带)内。
在一些实施例中，该DCI仅用于同时(即一次)调度两个或两个以上小区，或者该DCI既可以用于同时(即一次)调度两个或两个小区，也可以用于(一次)调度仅一个小区。
在一些实施例中，DCI的格式可以是第一DCI格式，该第一DCI格式例如可以 是用于支持多小区调度(multi-cell scheduling)的DCI format。具体地，例如，该第一DCI格式是DCI format 1_1和/或0_1，或者，DCI format 1_2和/或0_2，或者，为了支持multi-cell scheduling新引入的DCI format(例如，DCI format 1_3和/或0_3)等。但本申请实施例并不以此作为限制。例如不区分用于仅支持多小区调度(multi-cell scheduling)的DCI format和其他DCI格式，该DCI的格式是用于调度PDSCH和/或PUSCH的任意DCI格式，此处不再一一举例。
换句话说，该DCI调度M个小区上的PDSCH和/或PUSCH，但该DCI可以仅支持多小区调度(multi-cell scheduling)，或者该DCI可以支持单小区调度和多小区调度。
在一些实施例中，该DCI调度的M个小区可以是预定义的或者配置的，或者可以由该DCI动态(显式或隐式)指示，例如，由DCI中的第一信息域，第二信息域，第三信息域，第四信息域中的至少一个信息域动态(显式或隐式)指示，该方法还可以包括：(未图示)
该终端设备接收第一配置信息和/或第一激活/去激活信息，该第一配置信息和/或第一激活/去激活信息包括用于指示该第一小区和/或至少一个第二小区的信息，和/或，该至少一个子小区组的信息，和/或，该第一小区和/或至少一个第二小区中可以由同一个DCI调度的子小区组合的信息。
在一些实施例中该第一配置信息由RRC信令承载，可以包括该第一小区的小区配置信息或者该第一小区的小区配置信息中的跨载波调度配置信息CrossCarrierSchedulingConfig)，和/或，该第二小区的小区配置信息或者该第二小区的小区配置信息中的跨载波调度配置信息CrossCarrierSchedulingConfig)，和/或，主小区组或辅小区组的配置信息，具体后述会举例说明。
在一些实施例中，该第一激活/去激活信息可以由MAC CE承载。第一激活/去激活信息用于激活和/或去激活预定义的和/或第一配置信息配置的子小区组和/或可以由同一个DCI调度的子小区组合。
在一些实施例中，针对该DCI，可以根据第一配置信息和/或第一激活/去激活信息确定调度的M个小区，无需结合DCI中信息域，或者，可以根据第一配置信息和/或第一激活/去激活信息，结合该DCI中的信息域指示/确定调度的M个小区，例如根据所述第一配置信息和/或第一激活/去激活信息确定所述DCI中的信息域的值或者信 息域的部分字段的值对应的小区或子小区组合。
以下分别说明。
在一些实施例中，该M个小区为该第一小区和N个第二小区，也就是说该DCI调度的M个小区相当于该DCI调度该第一小区和N个第二小区，该第一小区和N个第二小区是预定义或配置的(例如RRC信令和/或MAC信令)，在DCI为第一DCI格式时，该DCI调度的M个小区是预定义或配置(例如第一配置信息)的第一小区和N个第二小区。
例如，该第一配置信息指示该第一小区和N个第二小区的信息(第二指示信息)，该第一配置信息针对第一DCI格式，在第一DCI格式为多个时，第一配置信息分别针对不同的第一DCI格式(例如针对上行和下行不同)配置第一小区和N个第二小区的信息，例如，该第一配置信息包含对应该第一小区和N个第二小区的CIF的值，可选的，还可以包含与配置第一小区和N个第二小区的信息对应的第一DCI格式指示信息。
在一些实施例中，该M个小区由该DCI动态(显式或隐式)指示。以下先结合附图4A至4C对DCI中的各种信息域进行说明。
图4A是DCI格式一示意图，如图4A所示，该DCI中的一个信息域(例如后述第一信息域或者第二信息域)用于显式指示DCI调度的小区，该DCI还包括第三信息域/或第四信息域，该第三信息域和/或第四信息域可以是公共的或小区特定的或小区组特定的信息域，该第三信息域和/或第四信息域可以是频率资源分配域或时域资源分配域等，此处不再一一举例，该第三信息域和/或第四信息域可以隐式指示DCI调度的小区，或者不用于指示DCI调度的小区。
图4B是DCI格式一示意图，如图4B所示，该DCI中的两个或两个以上信息域(例如后述第一信息域和第二信息域)用于显式指示DCI调度的小区，该DCI还包括第三信息域/或第四信息域，该第三信息域和/或第四信息域可以是公共的或小区特定的或小区组特定的信息域，该第三信息域和/或第四信息域可以是频率资源分配域或时域资源分配域等，此处不再一一举例，该第三信息域和/或第四信息域可以隐式指示DCI调度的小区，或者不用于指示DCI调度的小区。
图4C是DCI格式一示意图，如图4C所示，该DCI中不包括显式指示DCI调度的小区的信息域，该DCI还包括第三信息域/或第四信息域，该第三信息域和/或第四 信息域可以是公共的或小区特定的或小区组特定的信息域，该第三信息域和/或第四信息域可以是频率资源分配域或时域资源分配域等，此处不再一一举例，该第三信息域和/或第四信息域可以隐式指示DCI调度的小区。
在一些实施例中，该第一信息域可以是利用DCI现有的载波指示域(CIF)(可以修改指示方式)，该第二信息域可以是新增的信息域，但此处仅为示例说明，本申请实施例并不以此作为限制。
以下结合附图4A至4C分别说明DCI调度的小区的指示/确定方式。
在一些实施例中，如图4C所示，DCI不包括显式的指示调度的小区的信息域，DCI可以包括或不包括第三信息域，在所述第三信息域针对的一个或多个小区没有被调度时，所述第三信息域的值为第一值或者所述DCI不包括第三信息域或者所述终端设备忽略所述第三信息域。该第三信息域的数量为至少两个，该至少两个信息域分别在该DCI中的比特位置是连续的或者离散的，每个第三信息域包括一个或连续多个比特，终端设备可以根据第三信息域的值确定所述DCI调度的M个小区。
例如，该第三信息域是小区特定的或者小区组特定的信息域，即不同的第三信息域对应不同的子小区组或者小区，第三信息域通过第一值指示相应的子小区组或小区没有被调度。或者说，如果一个子小区组或小区没有被调度，则相应的第三信息域设为该第一值或者不包括第三信息域。在第三信息域的值不为第一值时，隐式地指示相应的子小区组或小区被调度，例如，第三信息域是频率资源分配域，用于显式地指示对应小区或对应子小区组上的调度的PDSCH和/或PUSCH频率资源，该第三信息域共有3个，分别对应子小区组1，子小区组2，子小区组3，第一个第三信息域的值为第一值或者不包括第一个第三信息域，子小区组1没有被调度，第二个第三信息域的值为不为第一值(为第四值)时，子小区组2被调度，该第四值用于指示子小区组2上调度的PDSCH和/或PUSCH频率资源，第三个信息域的值为不为第一值(为第五值)时，子小区组3被调度，该第五值用于指示子小区组3上调度的PDSCH和/或PUSCH频率资源。
在一些实施例中，DCI包括第四信息域，第四信息域包括第一字段和/或第二字段，在该第一字段或第二字段针对的一个或多个小区没有被调度时，该第一字段或第二字段的值为第二值或者该第四信息域不包括该第一字段或第二字段，或者该终端设备忽略该第一字段或第二字段，终端设备可以根据第四信息域的值确定该DCI调度 的M个小区。
例如，该第四信息域包括第一字段和/或第二字段，第二字段和第一字段包括的比特有交集或者没有交集，不同的字段对应不同的子小区组或者小区，第一字段和/或第二字段通过第二值或者不包括第一字段和/或第二字段指示相应的子小区组或小区没有被调度。或者说，如果一个子小区组或小区没有被调度，则相应的第一字段和/或第二字段设为该第二值或者不包括第一字段和/或第二字段。例如，第四信息域包括第一字段和第二字段，分别对应子小区组1，子小区组2，第一字段的值为第二值或者不包括第一字段，子小区组1没有被调度，第二字段的值为不为第二值或者包括第二字段，子小区组2被调度，此处不再一一举例。
以上，可以通过第一配置信息确定第三信息域或第四信息域的值或第四信息域的部分字段的值对应的小区或子小区组，具体实施方式如前所述，此处不再一一赘述。
在一些实施例中，DCI包括第一信息域，该第一信息域用于显式指示DCI调度的小区。例如一个CIF的值可以对应多个小区，在DCI的第一信息域为该CIF值时，指示调度该CIF值对应的多个小区，该DCI的下行分配或上行授权针对该多个小区，例如该第一信息域可以是现有的CIF。
例如，可以针对每个小区预定义和/或配置对应的一个或多个CIF值，也可以针对每个CIF至预定义或配置一个或多个小区。以下以针对每个小区配置(通过第一配置信息配置)对应的一个或多个CIF值为例说明，预定义对应的一个或多个CIF值的方式类似，此处不再一一举例。
例如，第一配置信息包括该第一小区和/或该第二小区的小区配置信息(中的跨载波调度配置信息)，该第一小区和/或该第二小区的小区配置信息包括第一指示信息，该第一指示信息用于指示该第一小区或该第二小区对应的一个或多个第一信息域值。该第一配置信息由RRC信令承载，终端设备根据该第一配置信息可以确定第一小区和/或第二小区和第一信息域值的对应关系(第一信息域的值对应的小区或子小区组合)，换句话说，可以知道每个第一信息域值对应第一小区和/或第二小区中的哪些小区，进而，在DCI指示一个第一信息域值时结合该对应关系确定调度的M个小区。
该第一指示信息可以以序列或者比特位图的方式指示一个或多个第一信息域值，该第一小区的跨载波调度配置信息使用抽象语法标记ASN.1数据格式(序列值)可以表示为：
CrossCarrierSchedulingConfig information element
Figure PCTCN2022090098-appb-000001
因此，第一指示信息cif-InSchedulingCellList-r18用于指示该第一小区或该第二小区对应的一个或多个第一信息域值，类似的，各个第二小区的跨载波调度配置信息也包括第一指示信息cif-InSchedulingCellList-r18用于指示该第一小区或该第二小区对应的一个或多个第一信息域值，例如，第一小区为小区1，第二小区包括小区2，小区3，小区4，小区1的跨载波调度配置信息的第一指示信息指示CIF值为0,4,5,6，10,11,12,14，小区2的跨载波调度配置信息的第一指示信息指示CIF值为 1,4,7,8,10,12,13,14，小区3的跨载波调度配置信息的第一指示信息指示CIF值为2,5,7,9,10,11,13,14，小区4的跨载波调度配置信息的第一指示信息指示CIF值为3,6,8,9,11,12,13,14，每个CIF值和小区的映射关系如下，具体如下表1所示：

因此，在DCI的第一信息域值为9(例如1001)时，指示调度小区3和4，在第一信息域的值为14时，指示调度小区1,2,3,4。

该第一小区的跨载波调度配置信息使用抽象语法标记ASN.1数据格式(比特位图)可以表示为：

Figure PCTCN2022090098-appb-000003
第一指示信息cif-InSchedulingCellList-r18用于指示该第一小区或该第二小区对应的一个或多个第一信息域值，类似的，各个第二小区的跨载波调度配置信息也包括第一指示信息cif-InSchedulingCellList-r18用于指示该第一小区或该第二小区对应的一个或多个第一信息域值，例如，第一指示信息为比特位图，每一个比特对应一个CIF值，例如，小区1的跨载波调度配置信息的第一指示信息为10001110，则指示CIF值为0,4,5,6，小区2的跨载波调度配置信息的第一指示信息为01001001，指示CIF值为1,4,7，小区3的跨载波调度配置信息的第一指示信息为00100101，指示CIF值为2,5,7，小区4的跨载波调度配置信息的第一指示信息为00010010，指示CIF值为3,6。因此，在DCI的第一信息域值为0110(CIF值为6)时，指示调度小区1和4，在第一信息域的值为0111时，指示调度小区2和3。
在一些实施例中，针对第一信息域的值等于0，仅对应第一小区，第一小区对应的第一信息域的值的范围包括0。也就是说，第二小区对应的第一信息域的值的范围不包括0，第一信息域的值为0仅用于单独调度第一小区，当需要同时调度第一小区和第二小区时，第一信息域的值不为0。此处仅为示例说明，例如，第二小区对应的第一信息域的值的范围也可以包括0。
在现有方法中，第一信息域为0不能在跨载波调度配置信息中配置，而是预定义为对应第一小区，为了支持多小区调度，该第一指示信息能够指示的第一信息域值的范围包括0或者不包括0。
在一些实施例中，针对第一小区和第二小区的第一指示信息能够指示的第一信息域的值的范围相同或不同，和/或,能够配置的第一信息域的值的数量相同或不同。在不同时，例如，针对第一小区的第一指示信息能够指示的第一信息域的值的范围不包括0(可选地，缺省的，其对应的第一信息域的值包括0)，针对第二小区的第一指示信息能够指示的第一信息域的值的范围包括0。在相同时，例如，针对第一小区和第二小区的第一指示信息能够指示的第一信息域的值的范围都包括0或者都不包括0。
例如，针对表1，针对第二小区的第一指示信息能够指示的第一信息域的值的范围不包括0，针对表3，针对第二小区的第一指示信息能够指示的第一信息域的值的范围包括0。
在一些实施例中，在针对第一小区的第一指示信息能够指示的第一信息域的值的范围都包括0时，如果不包括该第一指示信息，则缺省的，配置的第一信息域的值为0。
在以上示例中，该第一信息域作为一个整体指示DCI调度的M个小区，在一些实施例中，使用第一信息域包括第三字段和/或第四字段，在该第三字段或第四字段针对的一个或多个小区没有被调度时，该第三字段或第四字段的值为第三值，终端设备可以根据第一信息域中各个字段的值确定该DCI调度的M个小区。
例如，该第一信息域包括第三字段和/或第四字段，第四字段和第三字段包括的比特有交集或者没有交集，不同的字段对应不同的子小区组或者小区，第三字段和/或第四字段通过第三值指示相应的子小区组或小区没有被调度。或者说，如果一个子小区组或小区没有被调度，则相应的第三字段和/或第四字段设为该第三值。例如，第一信息域包括第三字段和第四字段，分别对应子小区组1，子小区组2，第三字段的值为第三值，子小区组1没有被调度，第四字段的值为不为第三值，子小区组2被调度，此处不再一一举例。
在以上示例中，该DCI中包括一个第一信息域，指示调度的M个小区，在一些实施例中，该DCI可以包括至少两个第一信息域，不同的第一信息域对应不同的子小区组或者小区。例如，在一个第一信息域针对的一个小区或子小区组没有被调度时，所述第一信息域的值为第三值。
例如，第一信息域通过第三值指示相应的子小区组或小区没有被调度。或者说，如果一个子小区组或小区没有被调度，则相应的第一信息域设为该第三值。在第一信息域的值不为第三值时，指示相应的子小区组或小区被调度。
以上，不同第一信息域，或者不同字段对应的小区或子小区组有交集或没有交集。该第一信息域或字段与小区或子小区组的对应关系的配置方式与前述第一配置信息类似，此处不再一一举例，终端设备可以根据该第一配置信息确定第一信息域的值或第一信息域的部分字段的值对应的小区或子小区组。
在一些实施例中，前述第一信息域通过指示CIF的值的方式指示调度的小区，但 本申请实施例并不以此作为限制，例如，可以不基于指示CIF的值指示调度的小区，以下举例说明。
在一些实施例中，DCI包括第一信息域或第二信息域，所述第一信息域或第二信息域以比特位图，或者RIV的形式指示调度的小区，或者第一信息域或第二信息域用于指示子小区组索引，终端设备根据第一信息域或第二信息域的值确定DCI调度的小区，以下以比特位图为例说明，不同比特对应不同的小区或子小区组。
例如，该比特位图可以指示的小区范围为第一小区和/或N个第二小区，即该比特位图可以指示的小区为能够被第一小区调度的小区或者能够被DCI调度的小区。
例如，该比特位图可以指示的小区范围为一个子小区组中的小区，可选的除第一小区或被配置了CIF值的第二小区外，也就是说，该比特位图指示与DCI中CIF的值对应的小区相关联的小区，但本申请实施例并不以此作为限制。
例如，该比特位图可以指示的小区范围为与配置或预定义CIF的值对应的小区相关联的小区，可选的除第一小区或被配置了CIF值的第二小区外，也就是说，该比特位图指示与DCI中CIF的值对应的小区相关联的小区，与前述不同之处在于，该相关联的小区不限于在在同一个小区内，该相关联的小区可以是跨子小区组的。
例如，该比特位图可以指示的小区范围为一个子小区组中的小区，该子小区组也包括第一小区，或者，比特位图可以指示的小区范围为能够被第一个DCI格式调度的小区。与前述不同之处在于，该调度的小区不限于在在同一个小区内，该相关联的小区可以是跨子小区组的。
以上，该第一信息域或第二信息域与小区或子小区组的对应关系的配置方式与前述第一配置信息类似，终端设备可以根据该第一配置信息确定第一信息域或第二信息域的值对应的小区或子小区组，此处不再一一举例。
在一些实施例中，该DCI包括第一信息域，该第一信息域用于指示该DCI调度的小区中的一个小区，也就是与现有类似，在配置或预定义第一信息域的值时，第一信息域的值与小区一一对应，通过前述第一配置信息指示至少一个子小区组的信息，例如，在一个小区的小区配置信息中指示该至少一个子小区组是与该一个小区关联的至少一个子小区组，由此，当DCI指示一个第一信息域的值时，根据该第一配置信息可以确定与该第一信息域的值对应的小区关联的至少一个子小区组，该一个第一信息域的值对应的小区以及和该小区关联的至少一个子小区组里的小区为该DCI调度 的M个小区。
可选的，在配置关联的子小区组为多组时，还可以通过激活/去激活信息，或第二信息域从该一个小区所在的一个或多个子小区组合中指示调度的子小区组合，或者，用于从与该一个小区关联的一个或多个子小区组合中指示调度的子小区组合，或者，用于指示该DCI调度的小区中该一个小区以外的一个或多个小区(或者说从多组中指示/激活一个子小区组)，例如该激活/去激活信息为激活的一个子小区组的组索引，该第二信息域的值为一个子小区组的组索引，在该情况下第一小区和N个第二小区等同于激活的一个子小区组中的小区。具体如下表4所示：(灰色格子为CIF值对应的小区，条纹格子为关联小区)
表4
Figure PCTCN2022090098-appb-000004
在一些实施例中，该DCI包括第一信息域和第二信息域，该第一信息域和第二信息域联合指示DCI调度的小区，终端设备根据该第一信息域和第二信息域的值确定DCI调度的M个小区。
例如，该第二信息域用于指示子小区组索引，该第一信息域用于指示该第二信息域指示的子小区组中被该DCI调度小区。与前述方法不同之处在于，第一信息域指示的调度小区的范围是第一小区和第二小区中的子小区组中的小区，具体指示方式可以参考前述实施例，此处不再一一赘述。
在一些实施例中，该DCI包括第二信息域，该第二信息域用于指示调度的小区 的数量M，终端设备根据该第二信息域的值确定DCI调度的M个小区。例如，可以通过第一配置信息配置多种调度小区图样(pattern)，每个图样对应的调度小区的数量不同，每个图样指示调度哪些小区，由此，终端设备根据该第二信息域指示的调度小区的数量，即可以确定与该数量对应的图样，根据该图样确定调度的M个小区。需要说明的是，在前述根据第一信息域和/或第二信息域的值确定DCI调度的小区时，在确定一个小区或子小区组没有被调度时，与该小区或子小区组对应的第三信息域取值为第二值，或者不包括对应的第三信息域或者终端设备忽略对应的第三信息域，或者与该小区或子小区组对应的第四信息域的第一字段或第二字段取值为第二值，或者不包括对应的第三信息域或者终端设备忽略对应的第三信息域，具体实施方式可以参考前述实施例，此处不再赘述。
由上述实施例可知，可以支持通过一个DCI调度多个服务小区的PDSCH和/或PUSCH，进而减轻终端设备的DCI监听负担，降低耗电量以及复杂度。
