Description

信息域确定、指示方法和装置、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，涉及信息域确定方法、信息域指示方法、信息域确定装置、信息域指示装置、通信装置和计算机可读存储介质。
背景技术
在动态频谱共享(Dynamic Spectrum Sharing，DSS)场景下，主小区(Primary Cell，PCell)和主辅小区(Primary Secondary Cell，PSCell)可以作为被调度小区，主小区和主辅小区可以简化称作P(S)Cell，用于调度P(S)Cell的小区可以称作调度服务小区sScell(Scheduling Scell)。
在这种情况下，终端需要监听两种下行控制信息(Downlink control information，DCI)，一种DCI用于P(S)Cell内自调度，另一种DCI用于sSCell跨载波调度(Cross-Carrier Scheduling，CCS)P(S)Cell，这两种DCI中信息域的状态可以有所不同。因此，对于终端而言，如何准确区分这两种DCI中信息域的状态，是亟待解决的问题。
发明内容

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SS配置信息也可以被称为第二SS配置信息，类似地，第二SS配置信息也可以被称为第一SS配置信息。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。
在动态频谱共享(Dynamic Spectrum Sharing，DSS)场景下，调度服务小区sScell(Scheduling Scell)可以通过跨载波调度(Cross-Carrier Scheduling，CCS)，调度P(S)Cell(主小区(Primary Cell，PCell)和主辅小区(Primary Secondary Cell，PSCell)，主小区和主辅小区可以简化称作P(S)Cell)的物理下行共享信道(PDSCH，Physical Downlink Shared Channel)、物理上行共享信道(PUSCH，Physical Uplink Shared Channel)等数据。据此，部分起到调度作用的物理下行控制信道(PDCCH，Physical Downlink Control CHannel)通过sScell进行传输，有利于降低P(S)Cell上的信令开销。
当然，P(S)Cell也可以作为调度小区，进行小区内调度，调度本小区发送的数据(例如PDSCH、PUSCH)。
因此，在这种情况下，终端需要监听monitor两种下行控制信息(Downlink control information，DCI)，一种DCI用于P(S)Cell内自调度，另一种DCI用于sSCell跨载波调度(Cross-Carrier Scheduling，CCS)P(S)Cell。这两种DCI的格式是相同的，例如均为DCI format 1_1。
在相同DCI format条件下，上述两种功能的DCI长度可能不同，UE需要在现有机制的基础上，增加一种可能的盲检DCI长度，从而增加了用户盲检DCI的复杂度。为降低DCI盲检的复杂度，其中一种可能的策略，是实现上述两种功能的DCI的长度对齐。而为了实现上述两种DCI的长度对齐，一种可能的实现方式是在DCI用于跨载波调度时，其中的载波指示域(Carrier Indicator Field，CIF)对应的比特数，与DCI用于小区内自调度时DCI中CIF对应的比特数相同，例如均占用3bits，那么对于这两种DCI，终端需要盲检的DCI的长度(对应比特数)是相同的，有利于降低终端盲检DCI的开销。其中，在DCI用于跨载波调度时，DCI中的CIF对应比特用于指示跨载波调度的载波；在DCI用于小区内自调度时，DCI中的CIF对应比特位为预留状态，并不用于指示。
那么当终端接收到上述格式的DCI时，DCI中的CIF可能存在两种状态，一种 是用于载波指示，也即指示跨载波调度中，所述DCI是针对哪个分量载波，另一种是预留状态。因此，就需要终端准确区分这两种情况下CIF对应比特的状态。
图1是根据本公开的实施例示出的一种信息域确定方法的示意流程图。本实施例所示的信息域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1所示，所述信息域确定方法可以包括以下步骤：
在步骤S101中，根据网络设备发送的指示信息或者根据预定义规则，确定所述网络设备发送的下行控制信息DCI中载波指示域CIF对应比特(bits)的状态。
在本公开的所有实施例中，与终端通信的网络设备可以是P(S)Cell对应的基站，也可以是sSCell对应的基站。
在一个实施例中，在动态频谱共享场景中，网络设备可以向终端发送指示信息，终端可以接收网络设备发送的指示信息，并根据指示信息确定网络设备发送的DCI中CIF对应比特的状态。
其中，所述指示信息包括以下至少之一：
无线接入控制(RRC，Radio Resource Control)信令、DCI、媒体接入控制控制元素(MAC CE，Media Access Control Control Element)。
网络设备可以在指示信息中设置新的信息域，并通过新的信息域指示所发送的DCI中CIF对应比特的状态。
在一个实施例中，终端也可以根据预定义规则确定网络设备发送的DCI中CIF对应比特的状态，所以预定义规则可以是协议约定的。
需要说明的是，无论终端根据网络设备发送的指示信息确定CIF对应比特的状态，还是根据预定义规则确定CIF对应比特的状态，网络设备也能够采取相同的方式确定CIF对应比特的状态。
根据本公开的实施例，终端通过接收网络设备发送的指示可以确定网络设备发送的DCI中CIF对应比特的状态，也可以根据预定义规则确定网络设备发送DCI中CIF对应比特的状态。据此，后续网络设备在向终端发送DCI时，终端就可以准确地确定DCI中CIF对应比特的状态，进而实现对CIF对应比特指示信息的正确解读，有 利于后续数据解调的准确性。
在一个实施例中，所述CIF对应比特的状态包括以下至少之一：
所述CIF对应比特用于载波指示；
所述CIF对应比特为预留(reserved)状态；
所述CIF对应比特用于指示其他信息，这种情况是对CIF对应比特的重耕，也即将CIF对应比特用作“载波指示”以外的其他指示功能。
在本公开的所有实施例中，所述CIF对应比特用于指示的其他信息，可以通过配置指示除载波指示以外的“其他信息”，或者可以根据预定义规则规定除载波指示以外的“其他信息”。例如所述CIF对应比特用于指示的其他信息为动态地激活/去激活sSCell对P(S)Cell的跨载波调度(dynamic activation/deactivation of CCS from sSCell to P(S)Cell)。
图2是根据本公开的实施例示出的应用场景示意图。
如图2所示，sSCell对应的DCI(例如sSCell对应的基站发送的DCI)可以调度P(S)Cell上的数据(例如PDSCH、PUSCH)，那么sSCell对应的DCI(例如sSCell对应的基站发送的DCI)中的CIF对应比特可以用于载波指示，调度P(S)Cell上的数据。P(S)Cell对应DCI(例P(S)Cell对应的基站发送DCI)用于小区内自调度，CIF对应比特可以是预留状态。
而无论CIF对应比特的状态是什么，CIF对应比特的数量是相同的。例如在图2中，当CIF对应比特用于载波指示时，以及在CIF对应比特为预留状态时，或者CIF对应比特用于指示其他信息时，CIF对应比特的数量都是相同的，例如可以为3个bits，以确保CIF对应比特是对齐的。
终端确定网络设备发送的DCI中CIF对应比特的状态，主要包括两种方式，例如根据网络设备发送的指示信息确定，或者根据预定义规则确定。
以下通过几个实施例示例性说明终端根据预定义规则确定网络设备发送的DCI中CIF对应比特的状态。
在一个实施例中，所述预定义规则包括以下至少之一：
接收第一搜索空间SS(Search Space)配置信息，在所述第一SS配置信息只包含SS标识信息和候选物理下行控制信道PDCCH candidates数目信息的情况下，所 述第一SS配置信息对应的DCI中CIF对应比特用于载波指示；和/或
接收第二SS配置信息，在所述第二SS配置信息包含SS标识信息和PDCCH candidates数目信息以及其他字段信息的情况下，根据所述第二SS配置信息盲检到的DCI中CIF对应比特为预留状态；和/或，
接收第二SS配置信息，所述第二SS配置信息包含SS标识信息和PDCCH candidates数目信息以及其他字段信息，根据所述第二SS配置信息盲检到的DCI中CIF对应比特用于指示其他信息。
需要说明的是，在本实施例中，第一SS配置信息和第二SS配置信息并非特指某个SS配置信息，只是为了区分包含不同信息的SS配置信息。
例如第一SS配置信息只包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)，简称为轻配置信息(light configuration)，第一SS配置信息可以应用于被调度小区。例如第一SS配置信息可以如下所示：
SeachSpace：＝
SEQUENCE{
seachSpaceID
nrofCandidates
}
而第二配置信息不仅包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)，还可以包含其他字段信息，简称为全配置信息(full configuration)，可以用于小区内自调度。
其中，其他字段信息包括但不限于控制资源集标识(controlResourceSetID)、监听时隙周期和补偿(monitoringSlotPeriodicityAndOffset)、持续时长(duration)、时隙内监听符号(monitoringSymbolWithinSlot)、搜索空间类型(searchSpaceType)等。
例如第二SS配置信息可以如下所示：
SeachSpace：＝
SEQUENCE{
seachSpaceID
controlResourceSetID
monitoringSlotPeriodicityAndOffset
duration
monitoringSymbolWithinSlot
nrofCandidates
searchSpaceType
……
}
终端根据预定义规则，在接收到第一SS配置信息时，可以确定第一SS配置信息对应的DCI中CIF对应比特用于载波指示，在接收到第二SS配置信息时，可以确定根据第二SS配置信息盲检到的DCI中CIF对应比特为预留状态，或者用于指示其他信息。据此，终端可以根据接收到的SS配置信息，就能够确定SS配置信息对应的DCI中CIF对应比特用于载波指示还是为预留状态，或者用于指示其他信息，从而可以准确且快速地确定DCI中CIF对应比特的状态，实现对CIF对应比特的正确解析。
需要说明的是，在本公开的所有实施例中，接收到的SS配置信息对应的DCI，是指终端根据接收到的SS配置信息中SS标识信息，确定的其他SS配置信息，并根据接收到的SS配置信息(例如其中的nrofCandidates)和其他SS配置信息盲检到的DCI。其他SS配置信息中的SS标识信息与接收到的SS配置信息中的SS标识信息相同。
例如第一SS配置信息对应的DCI，是指终端根据第一SS配置信息中SS标识信息，确定的其他SS配置信息，并根据第一SS配置信息(例如其中的nrofCandidates)和其他SS配置信息盲检到的DCI。其他SS配置信息中的SS标识信息与第一SS配置信息中的SS标识信息相同。
在一个实施例中，所述预定义规则包括以下至少之一：
接收第三SS配置信息，在所述第三SS配置信息的标识属于第一标识集合的情况下，所述第三SS配置信息对应的DCI或根据所述第三SS配置信息盲检到的DCI中CIF对应比特用于载波指示；和/或
接收第四SS配置信息，在所述第四SS配置信息的标识属于第二标识集合的情 况下，所述第四SS配置信息对应的DCI或根据所述第四SS配置信息盲检到的DCI中CIF对应比特为预留状态，或者用于指示其他信息。
从而终端可以根据SS配置信息中SS ID所属的标识集合，确定SS配置信息对应的DCI或者根据SS配置信息盲检到的DCI中CIF对应比特的状态。
在一个实施例中，所述方法还包括：根据预定义规则或根据网络设备的指示确定所述第一标识集合和/或所述第二标识集合。也即第一标识集合和/或所述第二标识集合，可以是预定义规则所规定的，也可以是网络设备根据需要指示的。
需要说明的是，在本实施例中，第三SS配置信息和第四SS配置信息并非特指某个SS配置信息，而是为了针对包含不同信息时的SS配置信息进行区别。
例如预定义规则可以规定终端在接收到第三SS配置信息后，若第三SS配置信息中的标识属于第一标识集合，那么可以判定第三SS配置信息对应的DCI或者根据所述第三SS配置信息盲检到的DCI中CIF对应比特用于载波指示；预定义规则还可以规定终端在接收第四SS配置信息，若第四SS配置信息的标识属于第二标识集合，那么终端根据第四SS配置信息盲检到的DCI中CIF对应比特为预留状态，或者用于指示其他信息。
其中，所述标识例如可以为SS配置信息中的searchSpaceID，简称SS ID。
例如SS ID的范围可以从0开始，至搜索空间最大数量maxNrofSearchSpaces减1。第一标识集合为{0,1,2}，第二标识集合为{3,4,…,maxNrofSearchSpaces-1}。
当终端接收到SS配置信息后，若确定SS配置信息中的SS ID为1，属于第一标识集合，该SS配置信息可以称作第三SS配置信息。那么可以确定第三SS配置信息对应的DCI中CIF对应比特用于载波指示。
其中，第三SS配置信息对应的DCI，是指在第三SS配置信息只包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)的情况下，根据第三SS配置信息中SS标识信息确定的其他SS配置信息，并根据第三SS配置信息(例如第三SS配置信息中的SS ID)和其他SS配置信息盲检到的DCI。其他SS配置信息中的SS标识信息与第三SS配置信息中的SS标识信息相同。
根据第三SS配置信息盲检到的DCI，是指在第三SS配置信息不仅包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)，还包含其他字段信息，例如控制资源集标识(controlResourceSetID)、监听时隙周期和补偿 (monitoringSlotPeriodicityAndOffset)、持续时长(duration)、时隙内监听符号(monitoringSymbolWithinSlot)、搜索空间类型(searchSpaceType)等信息时，终端根据第三SS配置信息在当前小区盲检到的DCI。
当终端接收到SS配置信息后，若确定SS配置信息中的SS ID为4，属于第二标识集合，该SS配置信息可以称作第四SS配置信息。那么可以确定第四SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为预留状态。
或者，当终端接收到SS配置信息后，若确定SS配置信息中的SS ID为3，属于第二标识集合，该SS配置信息可以称作第四SS配置信息。那么可以确定第四SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特用于指示其他信息。
其中，第四SS配置信息对应的DCI，是指在第四SS配置信息只包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)的情况下，根据第四SS配置信息中SS标识信息，确定的其他SS配置信息，并根据第四SS配置信息(例如第四SS配置信息中的SS ID)和其他SS配置信息盲检到的DCI。其他SS配置信息中的SS标识信息与第四SS配置信息中的SS标识信息相同。
根据第三SS配置信息盲检到的DCI，是指在第四SS配置信息不仅包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)，还包含其他字段信息，例如控制资源集标识(controlResourceSetID)、监听时隙周期和补偿(monitoringSlotPeriodicityAndOffset)、持续时长(duration)、时隙内监听符号(monitoringSymbolWithinSlot)、搜索空间类型(searchSpaceType)等信息时，终端根据第四SS配置信息在当前小区盲检到的DCI。
需要说明的是，以上实施例是针对两个标识集合的情况进行示例性描述，相对应地，终端根据SS配置信息中的SS ID所属的标识集合，可以确定CIF对应比特的两种状态。而在实际应用中，可以根据需要设置更多的标识集合，例如设置3个或以上标识集合，那么根据SS配置信息中的SS ID所属的标识集合，可以确定CIF对应比特的3个或以上数量的状态。
以3个标识集合为例，例如第一标识集合为{0}，第二标识集合为{1,2}、第三标识集合为{3,4,…,maxNrofSearchSpaces-1}。当终端接收到SS配置信息后，若确定SS配置信息中的SS ID属于第一标识集合，可以确定该SS配置信息对应的DCI或者 根据该SS配置信息盲检到的DCI中CIF对应比特用于载波指示；若确定SS配置信息中的SS ID属于第二标识集合，可以确定该SS配置信息对应的DCI或者根据该SS配置信息盲检到的DCI中CIF对应比特位预留状态；若确定SS配置信息中的SS ID属于第一标识集合，可以确定该SS配置信息对应的DCI或者根据该SS配置信息盲检到的DCI中CIF对应比特用于指示其他信息。
据此，终端在接收到SS配置信息后，若接收到的SS配置信息中的标识属于第一标识集合，可以确定SS配置信息对应的DCI中CIF对应比特用于载波指示；若接收到的SS配置信息的标识属于第二标识集合，可以确定SS配置信息对应的DCI中CIF对应比特为预留状态，或者用于指示其他信息。从而终端根据接收到的SS配置信息的标识所属的标识集合，就能够确定SS配置信息对应的DCI中CIF对应比特用于载波指示还是为预留状态，或者用于指示其他信息，从而可以准确且快速地确定DCI中CIF对应比特的状态。
第一标识集合与第二标识集合可以是网络设备预先配置给终端的，也可以是根据预定义规则预先确定的。
终端确定网络设备发送的DCI中CIF对应比特的状态，主要包括两种方式，例如根据网络设备发送的指示信息确定，或者根据预定义规则确定。
以下通过几个实施例示例性说明终端根据网络设备发送的指示信息确定网络设备发送的DCI中CIF对应比特的状态。
在一个实施例中，终端根据指示信息或根据预定义规则确定的CIF对应比特的状态，可以是CIF对应比特用于载波指示，这种情况下CIF所在的DCI可以用于跨载波调度，跨载波调度是指在当前小区接收的DCI用于调度其他载波上的数据，例如PDSCH、PUSCH。DCI中CIF对应比特用于指示跨载波调度的载波，例如指示跨载波调度的载波的标识ID(Identity)。据此，终端可以确定CIF对应比特所在的DCI并不是用于调度当前小区，而是用于调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
在一个实施例中，终端根据指示信息或根据预定义规则确定的CIF对应比特的状态，可以是CIF对应比特为预留状态，这种情况下CIF所在的DCI可以用于小区内自调度，小区内自调度是指在当前小区接收的DCI用于调度当前小区上的数据，例如PDSCH、PUSCH。DCI中CIF对应比特并不用于指示，而是预留。据此，终端可以确 定CIF对应比特所在的DCI是用于调度当前小区的数据，例如PDSCH、PUSCH。
在一个实施例中，在指示信息中，可以拓展一个信息域用于指示CIF对应比特的状态，以DCI作为指示信息时进行示例。
例如发送指示信息的网络设备为P(S)Cell对应的基站，在DCI中可以拓展一个信息域指示CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示CIF对应比特为预留状态，那么可以确定在P(S)Cell上接收到的DCI，是用于小区内自调度的，也即调度P(S)Cell上的PDSCH、PUSCH；在拓展的信息域的值为1时，用于指示CIF对应比特为用于载波指示，那么可以确定在P(S)Cell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
例如发送指示信息的网络设备为sSCell对应的基站，在DCI中可以拓展一个信息域指示CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示CIF对应比特为预留状态，那么可以确定在sSCell上接收到的DCI，是用于小区内自调度的，也即调度sSCell上的PDSCH、PUSCH；在拓展的信息域的值为1时，用于指示CIF对应比特为用于载波指示，那么可以确定在sSCell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
在一个实施例中，指示信息所指示的CIF对应比特的状态，除了上述实施例所描述的CIF对应比特用于载波指示，或者CIF对应比特为预留状态，还可以根据需要设置为指示其他状态，例如指示CIF对应比特用于指示其他信息。
例如发送指示信息的网络设备为P(S)Cell对应的基站，在DCI中可以拓展一个信息域指示CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示CIF对应比特指示动态地激活/去激活sSCell对P(S)Cell的跨载波调度；在拓展的信息域的值为1时，用于指示CIF对应比特为用于载波指示，那么可以确定在P(S)Cell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
例如发送指示信息的网络设备为sSCell对应的基站，在DCI中可以拓展一个信息域指示CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示CIF对应比特指示动态地激活/去激活sSCell对P(S)Cell的跨载波调度；在拓展的信息域的值为1时，用于指示CIF对应比特为用于载波指示，那么可以确定在sSCell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、 PUSCH。
以上几个实施例主要在指示信息为DCI的情况下，对确定CIF对应比特位的状态进行了示例性说明。而实际应用中，也可以将RRC信令或者MAC CE作为指示信息，例如以RRC信令为例，可以将RRC信令中的SS配置信息作为指示信息，具体可以对SS配置信息拓展信息域，通过拓展的信息域指示CIF对应比特位的状态。
例如发送指示信息的网络设备为P(S)Cell对应的基站，在SS配置信息中可以拓展一个信息域指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为预留状态或指示其他信息；在拓展的信息域的值为1时，用于指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为用于载波指示，那么可以确定在P(S)Cell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
例如发送指示信息的网络设备为sSCell对应的基站，在SS配置信息中可以拓展一个信息域指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为预留状态或指示其他信息；在拓展的信息域的值为1时，用于指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为用于载波指示，那么可以确定在sSCell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
需要说明的是，以上实施例中主要拓展的信息域为0或1的情况下进行示例，由于0和1仅为两个值，用于指示两种CIF对应比特的状态，实际上可以根据需要设置所拓展的信息域所能指示的值。例如所拓展的信息域可以指示3个或3个以上的值时，那么根据所拓展的信息域确定的CIF对应比特的状态至少包括以下三种：CIF对应比特用于载波指示、CIF对应比特为预留状态、CIF对应比特用于指示其他信息。
例如在拓展的信息域的值为00时，用于指示CIF对应比特为预留状态；在拓展的信息域的值为01时，用于指示CIF对应比特为用于载波指示；在拓展的信息域的值为10时，用于指示CIF对应比特指示动态地激活/去激活sSCell对P(S)Cell的跨载波调度。
图3是根据本公开的实施例示出的另一种信息域确定方法的示意流程图。如图3所示，根据所述指示信息确定所述网络设备发送的DCI中CIF对应比特的状态包括：
在步骤S301中，若根据所述指示信息确定所述DCI用于跨载波调度CCS，则确定所述DCI中的CIF对应比特用于载波指示；或者，若根据所述指示信息确定所述DCI用于小区内自调度，则确定所述DCI中的CIF对应比特为预留状态或者用于指示其他信息。
在一个实施例中，网络设备向终端发送的指示信息，可以直接指示DCI中CIF对应比特的状态，也可以间接指示DCI中CIF对应比特的状态。以间接指示为例，例如在指示DCI用于CCS的情况下，终端可以确定DCI中的CIF对应比特用于载波指示；例如在指示DCI用于小区内自调度的情况下，终端可以确定DCI中的CIF对应比特为预留状态，后者可以确定CIF对应比特被重耕为指示其他信息。
据此，终端在接收到指示信息后，可以根据指示信息所指示的DCI的功能确定DCI中的CIF对应比特的状态，若DCI用于跨载波调度CCS，那么可以确定DCI中的CIF对应比特用于载波指示，若DCI用于小区内自调度，那么可以确定DCI中的CIF对应比特为预留状态或者指示其他信息。从而可以确保终端在接收到DCI后，快速确定DCI中CIF对应比特的状态。
图4是根据本公开的实施例示出的又一种信息域确定方法的示意流程图。如图4所示，根据指示信息确定所述网络设备发送的DCI中CIF对应比特的状态包括：
在步骤S401中，根据所述指示信息中目标信息域的值确定所述CIF对应比特的状态；和/或根据所述指示信息中目标信息域是否存在确定所述CIF对应比特的状态。
在一个实施例中，网络设备可以通过指示信息中的目标信息域指示DCI中CIF对应比特的状态，所述目标信息域可以在指示信息中拓展的信息域，也可以复用指示信息中已有的信息域。
例如可以通过设置目标信息域的值来指示DCI中CIF对应比特的状态，终端接收到指示信息后，根据指示信息中目标信息域的值即可确定DCI中CIF对应比特的状态。例如目标信息域的值为1时，可以确定DCI中CIF对应比特用于载波指示；例如目标信息域的值为1时，可以确定DCI中CIF对应比特为预留状态。
例如可以通过设置目标信息域是否存在来指示DCI中CIF对应比特的状态，终端在接收到指示信息后，通过检测目标信息域是否存在，可以确定DCI中CIF对应比 特的状态。例如在目标信息域存在的情况下，可以确定DCI中CIF对应比特用于载波指示；例如目标信息域不存在的情况下，可以确定DCI中CIF对应比特为预留状态。
另外，还可以结合目标信息域的值和目标信息域是否存在来指示CIF对应比特的状态，以便指示更多的状态。例如在目标信息域存在的情况下，若目标信息域的值为1时，可以确定DCI中CIF对应比特用于载波指示，若目标信息域的值为1时，可以确定DCI中CIF对应比特为预留状态；在目标信息域不存在的情况下，可以确定DCI中CIF用于指示其他信息，例如指示动态地激活/去激活sSCell对P(S)Cell的跨载波调度。
据此，终端在接收到指示信息后，可以根据指示信息中目标信息域的值确定DCI中的CIF对应比特的状态，或者根据指示信息中的目标信息域是否存在确定DCI中的CIF对应比特的状态。从而可以确保终端在接收到DCI后，快速确定DCI中CIF对应比特的状态。
图5是根据本公开的实施例示出的一种信息域指示方法的示意流程图。本实施例所示的信息域指示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5所示，所述信息域指示方法可以包括以下步骤：
在步骤S501中，根据预定义规则或者通过向终端发送指示信息，确定所述网络设备向所述终端发送的下行控制信息DCI中载波指示域CIF对应比特(bits)的状态。
在一个实施例中，在动态频谱共享场景中，网络设备可以向终端发送指示信息，终端可以接收网络设备发送的指示信息，并根据指示信息确定网络设备发送的DCI中CIF对应比特的状态。
其中，所述指示信息包括以下至少之一：
无线接入控制RRC信令、DCI、媒体接入控制控制元素MAC CE。
网络设备可以在指示信息中设置新的信息域，并通过新的信息域指示所发送的DCI中CIF对应比特的状态。
在一个实施例中，终端也可以根据预定义规则确定网络设备发送的DCI中CIF 对应比特的状态，所以预定义规则可以是协议约定的。
需要说明的是，无论终端根据网络设备发送的指示信息确定CIF对应比特的状态，还是根据预定义规则确定CIF对应比特的状态，网络设备也能够采取相同的方式确定CIF对应比特的状态。
根据本公开的实施例，网络设备可以自主确定DCI中CIF对应比特的状态，进而通过指示信息向终端指示DCI中CIF对应比特的状态，使得终端确定网络设备发送的DCI中CIF对应比特的状态，据此，后续网络设备在向终端发送DCI时，终端就可以准确地确定DCI中CIF对应比特的状态，进而采取相对应的操作。网络设备与终端也可以根据预定义规则确定DCI中CIF对应比特的状态，从而对DCI中CIF对应比特的状态达成一致的理解，以便后组网络设备在向终端发送DCI时，终端能够准确确定DCI中CIF对应比特的状态。
在一个实施例中，所述CIF对应比特的状态包括以下至少之一：
所述CIF对应比特用于载波指示；
所述CIF对应比特为预留(reserved)状态；
所述CIF对应比特被重耕为指示其他信息。
所述CIF对应比特用于指示其他信息，这种情况是对CIF对应比特的重耕，也即将CIF对应比特用作“载波指示”以外的其他指示功能。
在本公开的所有实施例中，所述CIF对应比特用于指示的其他信息，可以通过配置指示“其他信息”，或者可以根据预定义规则规定“其他信息”。例如所述CIF对应比特用于指示的其他信息为动态地激活/去激活sSCell对P(S)Cell的跨载波调度(dynamic activation/deactivation of CCS from sSCell to P(S)Cell)。
无论CIF对应比特的状态是什么，CIF对应比特的数量是相同的。例如在图2中，当CIF对应比特用于载波指示时，以及在CIF对应比特为预留状态时，CIF对应比特的数量都是相同的，例如可以为3个bits，以确保CIF对应比特是对齐的。
以下通过几个实施例示例性说明网络设备根据预定义规则确定发送的DCI中CIF对应比特的状态。
在一个实施例中，所述预定义规则包括以下至少之一：
发送第一SS配置信息，在所述第一SS配置信息只包含SS标识信息和PDCCH  candidates数目信息的情况下，所述第一SS配置信息对应的DCI中CIF对应比特用于载波指示；和/或

发送第二SS配置信息，在所述第二SS配置信息包含SS标识信息和PDCCH candidates数目信息以及其他字段信息的情况下，根据所述第二SS配置信息盲检到的DCI中CIF对应比特用于指示其他信息。
需要说明的是，在本实施例中，第一SS配置信息和第二SS配置信息并非特指某个SS配置信息，只是为了区分包含不同信息的SS配置信息。
例如第一SS配置信息只包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)，简称为轻配置信息(light configuration)，可以用于跨载波调度。例如第一SS配置信息可以如下所示：
SeachSpace：＝
SEQUENCE{
seachSpaceID
nrofCandidates
}
而第二配置信息不仅包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)，还可以包含其他字段信息，简称为全配置信息(full configuration)，可以用于小区内自调度。
其中，其他字段信息包括但不限于控制资源集标识(controlResourceSetID)、监听时隙周期和补偿(monitoringSlotPeriodicityAndOffset)、持续时长(duration)、时隙内监听符号(monitoringSymbolWithinSlot)、搜索空间类型(searchSpaceType)等。
例如第二SS配置信息可以如下所示：
SeachSpace：＝
SEQUENCE{
seachSpaceID
controlResourceSetID
monitoringSlotPeriodicityAndOffset
duration
monitoringSymbolWithinSlot
nrofCandidates
searchSpaceType
……
}
网络设备根据预定义规则，可以通过发送第一SS配置信息，使得终端确定第一SS配置信息对应的DCI中CIF对应比特用于载波指示，也可以通过发送第二SS配置信息，使得终端确定根据所述第二SS配置信息盲检到的DCI中CIF对应比特为预留状态；
相对应地，终端根据预定义规则，在接收到第一SS配置信息时，可以确定第一SS配置信息对应的DCI中CIF对应比特用于载波指示，在接收到第二SS配置信息时，可以确定根据第二SS配置信息盲检到的DCI中CIF对应比特为预留状态，或者用于指示其他信息。据此，终端可以根据接收到的SS配置信息，就能够确定SS配置信息对应的DCI中CIF对应比特用于载波指示还是为预留状态，或者用于指示其他信息，从而可以准确且快速地确定DCI中CIF对应比特的状态，实现CIF对应比特的正确解析。
需要说明的是，第一SS配置信息对应的DCI，是指终端根据第一SS配置信息中SS标识信息，确定的其他SS配置信息，并根据第一SS配置信息(例如其中的nrofCandidates)和其他SS配置信息盲检到的DCI。其他SS配置信息中的SS标识信息与第一SS配置信息中的SS标识信息相同。
在一个实施例中，所述预定义规则包括以下至少之一：
发送第三SS配置信息，在所述第三SS配置信息的标识属于第一标识集合的情况下，所述第三SS配置信息对应的DCI或(终端)根据所述第三SS配置信息盲检到的DCI中CIF对应比特用于载波指示；和/或
发送第四SS配置信息，在所述第四SS配置信息的标识属于第二标识集合的情况下，所述第四SS配置信息对应的DCI或(终端)根据所述第四SS配置信息盲检到的DCI中CIF对应比特为预留状态或用于指示其他信息。
网络设备可以通过向终端发送包含属于不同标识集合的SS ID的SS配置信息，使得终端确定SS配置信息对应的DCI或者根据SS配置信息盲检到的DCI中CIF对应比特的状态。
在一个实施例中，所述方法还包括：根据预定义规则确定或向所述终端指示所述第一标识集合和/或所述第二标识集合。也即第一标识集合和/或所述第二标识集合，可以是预定义规则所规定的，也可以是网络设备根据需要指示的。
需要说明的是，在本实施例中，第三SS配置信息和第四SS配置信息并非特指某个SS配置信息，而是为了针对包含不同信息时的SS配置信息进行区别。
例如预定义规则可以规定在网络设备发送的第三SS配置信息中的标识属于第一标识集合时，第三SS配置信息对应的DCI或者根据所述第三SS配置信息盲检到的DCI中CIF对应比特用于载波指示；以及规定网络设备发送的第四SS配置信息中的标识属于第二标识集合时，第四SS配置信息对应的DCI或者根据所述第四SS配置信息盲检到的DCI中CIF对应比特为预留状态或用于指示其他信息。
相对应地，终端根据预定义规则，在接收到第三SS配置信息后，若第三SS配置信息中的标识属于第一标识集合，那么可以判定第三SS配置信息对应的DCI或者根据所述第三SS配置信息盲检到的DCI中CIF对应比特用于载波指示；预定义规则还可以规定终端在接收第四SS配置信息，若第四SS配置信息的标识属于第二标识集合，那么终端根据第四SS配置信息盲检到的DCI中CIF对应比特为预留状态，或者用于指示其他信息。
其中，所述标识例如可以为SS配置信息中的searchSpaceID，简称SS ID。
第一标识集合与第二标识集合可以是网络设备预先配置给终端的，也可以是根据预定义规则预先确定的。
例如SS ID的范围可以从0开始，至搜索空间最大数量maxNrofSearchSpaces减1。第一标识集合为{0,1,2}，第二标识集合为{3,4,…,maxNrofSearchSpaces-1}。
当网络设备需要指示SS配置信息对应的DCI或者根据SS配置信息盲检到的DCI中CIF对应比特用于载波指示时，可以选择向终端发送第三SS配置信息，例如 第三SS配置信息中SS ID为1，属于第一标识集合。
当终端接收到SS配置信息后，若确定SS配置信息中的SS ID为1，属于第一标识集合，该SS配置信息可以称作第三SS配置信息。那么可以确定第三SS配置信息对应的DCI或者根据第三SS配置信息盲检到的DCI中CIF对应比特用于载波指示。
其中，第三SS配置信息对应的DCI，是指在第三SS配置信息只包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)的情况下，根据第三SS配置信息中SS标识信息确定的其他SS配置信息，并根据第三SS配置信息(例如第三SS配置信息中的SS ID)和其他SS配置信息盲检到的DCI。其他SS配置信息中的SS标识信息与第三SS配置信息中的SS标识信息相同。
根据第三SS配置信息盲检到的DCI，是指在第三SS配置信息不仅包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)，还包含其他字段信息，例如控制资源集标识(controlResourceSetID)、监听时隙周期和补偿(monitoringSlotPeriodicityAndOffset)、持续时长(duration)、时隙内监听符号(monitoringSymbolWithinSlot)、搜索空间类型(searchSpaceType)等信息时，终端根据第三SS配置信息在当前小区盲检到的DCI。
当网络设备需要指示SS配置信息对应的DCI或者根据SS配置信息盲检到的DCI中CIF对应比特为预留状态时，可以选择向终端发送第四SS配置信息，例如第四SS配置信息中SS ID为4，属于第二标识集合。
当终端接收到SS配置信息后，若确定SS配置信息中的SS ID为4，属于第二标识集合，该SS配置信息可以称作第四SS配置信息。那么可以确定第四SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为预留状态。
或者，当网络设备需要指示SS配置信息对应的DCI或者根据SS配置信息盲检到的DCI中CIF对应比特用于指示其他信息时，可以选择向终端发送第四SS配置信息，例如第四SS配置信息中SS ID为3，属于第二标识集合。
当终端接收到SS配置信息后，若确定SS配置信息中的SS ID为3，属于第二标识集合，该SS配置信息可以称作第四SS配置信息。那么可以确定第四SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特用于指示其他信息。
其中，第四SS配置信息对应的DCI，是指在第四SS配置信息只包含SS标识 信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)的情况下，根据第四SS配置信息中SS标识信息，确定的其他SS配置信息，并根据第四SS配置信息(例如第四SS配置信息中的SS ID)和其他SS配置信息盲检到的DCI。其他SS配置信息中的SS标识信息与第四SS配置信息中的SS标识信息相同。
根据第三SS配置信息盲检到的DCI，是指在第四SS配置信息不仅包含SS标识信息(searchSpaceID)和PDCCH candidates数目信息(nrofCandidates)，还包含其他字段信息，例如控制资源集标识(controlResourceSetID)、监听时隙周期和补偿(monitoringSlotPeriodicityAndOffset)、持续时长(duration)、时隙内监听符号(monitoringSymbolWithinSlot)、搜索空间类型(searchSpaceType)等信息时，终端根据第四SS配置信息在当前小区盲检到的DCI。
需要说明的是，以上实施例是针对两个标识集合的情况进行示例性描述，相对应地，终端根据SS配置信息中的SS ID所属的标识集合，可以确定CIF对应比特的两种状态。而在实际应用中，可以根据需要设置更多的标识集合，例如设置3个或以上标识集合，那么根据SS配置信息中的SS ID所属的标识集合，可以确定CIF对应比特的3个或以上数量的状态。
以3个标识集合为例，例如第一标识集合为{0}，第二标识集合为{1,2}、第三标识集合为{3,4,…,maxNrofSearchSpaces-1}。
当网络设备需要指示SS配置信息对应的DCI或者根据SS配置信息盲检到的DCI中CIF对应比特用于载波指示时，可以选择向终端发送包含属于第一标识集合的SS ID的SS配置信息。当网络设备需要指示SS配置信息对应的DCI或者根据SS配置信息盲检到的DCI中CIF对应比特为预留状态时，可以选择向终端发送包含属于第二标识集合的SS ID的SS配置信息。当网络设备需要指示SS配置信息对应的DCI或者根据SS配置信息盲检到的DCI中CIF对应比特用于指示其他信息时，可以选择向终端发送包含属于第三标识集合的SS ID的SS配置信息。
据此，终端在接收到SS配置信息后，若接收到的SS配置信息中的标识属于第一标识集合，可以确定SS配置信息对应的DCI中CIF对应比特用于载波指示；若接收到的SS配置信息的标识属于第二标识集合，可以确定SS配置信息对应的DCI中CIF对应比特为预留状态，或者用于指示其他信息。从而终端根据接收到的SS配置信息的标识所属的标识集合，就能够确定SS配置信息对应的DCI中CIF对应比特用于载波指示还是为预留状态，或者用于指示其他信息，从而可以准确且快速地确定DCI 中CIF对应比特的状态。
终端确定网络设备发送的DCI中CIF对应比特的状态，主要包括两种方式，例如根据自主确定后通过指示信息指示给终端，或者根据预定义规则确定。
以下通过几个实施例示例性说明网络设备自主确定发送的DCI中CIF对应比特的状态后通过指示信息指示给终端。
在一个实施例中，网络设备向终端发送的指示信息可以指示发送的DCI中CIF对应比特用于载波指示，这种情况下CIF所在的DCI可以用于跨载波调度，跨载波调度是指在当前小区接收的DCI用于调度其他载波上的数据，例如PDSCH、PUSCH。DCI中CIF对应比特用于指示跨载波调度的载波，例如指示跨载波调度的载波的标识ID(Identity)。据此，终端可以确定CIF对应比特所在的DCI并不是用于调度当前小区，而是用于调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
在一个实施例中，网络设备向终端发送的指示信息可以指示发送的DCI中CIF对应比特的状态，可以是CIF对应比特为预留状态，这种情况下CIF所在的DCI可以用于小区内自调度，小区内自调度是指在当前小区发送的DCI用于调度当前小区上的数据，例如PDSCH、PUSCH。DCI中CIF对应比特并不用于指示，而是预留。据此，终端可以确定CIF对应比特所在的DCI是用于调度当前小区上的数据，例如PDSCH、PUSCH。
在一个实施例中，网络设备在指示信息中，可以拓展一个信息域用于指示CIF对应比特的状态，以DCI作为指示信息时进行示例。
例如发送指示信息的网络设备为P(S)Cell对应的基站，在DCI中可以拓展一个信息域指示CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示CIF对应比特为预留状态，那么可以确定在P(S)Cell上接收到的DCI，是用于小区内自调度的，也即调度P(S)Cell上的PDSCH、PUSCH；在拓展的信息域的值为1时，用于指示CIF对应比特为用于载波指示，那么可以确定在P(S)Cell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
例如发送指示信息的网络设备为sSCell对应的基站，在DCI中可以拓展一个信息域指示CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示CIF对应比特为预留状态，那么可以确定在sSCell上接收到的DCI，是用于小区内自调度的，也即调度sSCell上的PDSCH、PUSCH；在拓展的信息域的值为1时，用于指示CIF 对应比特为用于载波指示，那么可以确定在sSCell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
在一个实施例中，指示信息所指示的CIF对应比特的状态，除了上述实施例所描述的CIF对应比特用于载波指示，或者CIF对应比特为预留状态，还可以根据需要设置为指示其他状态，例如指示CIF对应比特用于指示其他信息。
例如发送指示信息的网络设备为P(S)Cell对应的基站，在DCI中可以拓展一个信息域指示CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示CIF对应比特指示动态地激活/去激活sSCell对P(S)Cell的跨载波调度；在拓展的信息域的值为1时，用于指示CIF对应比特为用于载波指示，那么可以确定在P(S)Cell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
例如发送指示信息的网络设备为sSCell对应的基站，在DCI中可以拓展一个信息域指示CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示CIF对应比特指示动态地激活/去激活sSCell对P(S)Cell的跨载波调度；在拓展的信息域的值为1时，用于指示CIF对应比特为用于载波指示，那么可以确定在sSCell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
以上几个实施例主要在指示信息为DCI的情况下，对确定CIF对应比特位的状态进行了示例性说明。而实际应用中，也可以将RRC信令或者MAC CE作为指示信息，例如以RRC信令为例，可以将RRC信令中的SS配置信息作为指示信息，具体可以对SS配置信息拓展信息域，通过拓展的信息域指示CIF对应比特位的状态。
例如发送指示信息的网络设备为P(S)Cell对应的基站，在SS配置信息中可以拓展一个信息域指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为预留状态或指示其他信息；在拓展的信息域的值为1时，用于指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为用于载波指示，那么可以确定在P(S)Cell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
例如发送指示信息的网络设备为sSCell对应的基站，在SS配置信息中可以拓展一个信息域指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特的状态。例如在拓展的信息域的值为0时，用于指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为预留状态或指示其他信息；在拓展的信息域的值为1时，用于指示SS配置信息对应的DCI或者根据第四SS配置信息盲检到的DCI中CIF对应比特为用于载波指示，那么可以确定在sSCell上接收到的DCI，是用于跨载波调度的，也即调度CIF所指示的载波上的数据，例如PDSCH、PUSCH。
需要说明的是，以上实施例中主要拓展的信息域为0或1的情况下进行示例，由于0和1仅为两个值，用于指示两种CIF对应比特的状态，实际上可以根据需要设置所拓展的信息域所能指示的值。例如所拓展的信息域可以指示3个或3个以上的值时，那么根据所拓展的信息域确定的CIF对应比特的状态至少包括以下三种：CIF对应比特用于载波指示、CIF对应比特为预留状态、CIF对应比特用于指示其他信息。
例如在拓展的信息域的值为00时，用于指示CIF对应比特为预留状态；在拓展的信息域的值为01时，用于指示CIF对应比特为用于载波指示；在拓展的信息域的值为10时，用于指示CIF对应比特指示动态地激活/去激活sSCell对P(S)Cell的跨载波调度。
图6是根据本公开的实施例示出的另一种信息域指示方法的示意流程图。如图6所示，通过向终端发送指示信息指示所述CIF对应比特的状态包括：
在步骤S601中，在所述指示信息指示所述DCI用于跨载波调度的情况下，所述DCI中的CIF对应比特用于载波指示；或者，在所述指示信息指示所述DCI用于小区内自调度的情况下，所述DCI中的CIF对应比特为预留状态。
在一个实施例中，网络设备向终端发送的指示信息，可以直接指示DCI中CIF对应比特的状态，也可以间接指示DCI中CIF对应比特的状态。以间接指示为例，例如在指示DCI用于CCS的情况下，终端可以确定DCI中的CIF对应比特用于载波指示；例如在指示DCI用于小区内自调度的情况下，终端可以确定DCI中的CIF对应比特为预留状态，后者可以确定CIF对应比特被重耕为指示其他信息。
据此，终端在接收到指示信息后，可以根据指示信息所指示的DCI的功能确定DCI中的CIF对应比特的状态，若DCI用于跨载波调度CCS，那么可以确定DCI中 的CIF对应比特用于载波指示，若DCI用于小区内自调度，那么可以确定DCI中的CIF对应比特为预留状态或者指示其他信息。从而可以确保终端在接收到DCI后，快速确定DCI中CIF对应比特的状态。
图7是根据本公开的实施例示出的又一种信息域指示方法的示意流程图。如图7所示，通过向终端发送指示信息指示所述CIF对应比特的状态包括：
在步骤S701中，通过设置所述指示信息中目标信息域的值指示所述CIF对应比特的状态；和/或通过设置所述指示信息中目标信息域是否存在指示所述CIF对应比特的状态。
在一个实施例中，网络设备可以通过指示信息中的目标信息域指示DCI中CIF对应比特的状态，所述目标信息域可以在指示信息中拓展的信息域，也可以复用指示信息中已有的信息域。
例如可以通过设置目标信息域的值来指示DCI中CIF对应比特的状态，终端接收到指示信息后，根据指示信息中目标信息域的值即可确定DCI中CIF对应比特的状态。例如目标信息域的值为1时，可以确定DCI中CIF对应比特用于载波指示；例如目标信息域的值为1时，可以确定DCI中CIF对应比特为预留状态。
例如可以通过设置目标信息域是否存在来指示DCI中CIF对应比特的状态，终端在接收到指示信息后，通过检测目标信息域是否存在，可以确定DCI中CIF对应比特的状态。例如在目标信息域存在的情况下，可以确定DCI中CIF对应比特用于载波指示；例如目标信息域不存在的情况下，可以确定DCI中CIF对应比特为预留状态。
另外，还可以结合目标信息域的值和目标信息域是否存在来指示CIF对应比特的状态，以便指示更多的状态。例如在目标信息域存在的情况下，若目标信息域的值为1时，可以确定DCI中CIF对应比特用于载波指示，若目标信息域的值为1时，可以确定DCI中CIF对应比特为预留状态；在目标信息域不存在的情况下，可以确定DCI中CIF用于指示其他信息，例如指示动态地激活/去激活sSCell对P(S)Cell的跨载波调度。
据此，终端在接收到指示信息后，可以根据指示信息中目标信息域的值确定DCI中的CIF对应比特的状态，或者根据指示信息中的目标信息域是否存在确定DCI中的CIF对应比特的状态。从而可以确保终端在接收到DCI后，快速确定DCI中CIF对应比特的状态。
