Description

一种通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
目前的新无线(new radio，NR)系统中，对于数据信道的时域资源可以是通过协议预定和/或通过高层信令动态指示。其中，高层信令动态指示可以是终端设备和基站建立RRC连接后，基站通过RRC信令为终端设备配置时域资源集合(例如时域资源表)。目前，基站可以通过RRC信令为终端设备配置特有格式对应的时域资源集合，例如基站可以配置DCI format 0_1格式的第一时域资源表和DCI format 0_2格式的第二时域资源表。但是时域资源表中有些行对应的时域资源可能存在对某些下行控制信息(downlink control information，DCI)格式的DCI来说并不适用的情况。比如DCI format 0_1或者DCI format 1_1被配置为slot(时隙)级别时域重复方式时，那这个时域资源表中的一些跨边界的时域资源可能不适合使用。为此，需要提供一种机制，可以保证终端设备和基站选择合适的时域资源来传输数据。
发明内容

本发明实施例中，网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的正常进行；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源有不同的特征，选择重复方式一致的时域资源集合能够保证时域重复方式能够保证时域资源集合中的所有时域资源都能够满足该时域重复方式的特征，保证正常通信。
在一种可能的设计中，该至少一个时域资源集合为一个时域资源集合，且为第一DCI格式对应的第一时域资源集合。终端设备还可以接收来自网络设备第一指示信息，该第一指示信息用于指示免授权调度的时域重复方式。终端设备根据免授权调度的时域重复方式和至少一个时域资源集合，确定免授权调度的第三时域资源集合。例如基站向终端发送第一指示信息，第一指示信息就用于告知终端设备时域重复方式为时隙级别时域重复方式，那么终端根据该第一指示信息就可以确定与该时隙级别时域重复方式对应的时域资源，这种方式较为简单直接。
在一种可能的设计中，网络设备除了向终端设备发送第一指示信息，网络设备还可以 向终端设备发送第二指示信息，该第二指示信息用于指示第一DCI格式的时域重复方式，以及用于指示所述第二DCI格式的时域重复方式。然后终端设备判断免授权调度的时域重复方式和所述第一DCI的时域重复方式和所述第二DCI的重复方式满足规则一时，则确定至少一个时域资源集合为所述免授权调度的第三时域资源集合。规则一：所述免授权调度的时域重复方式和所述第一DCI的时域重复方式和所述第二DCI的重复方式均相同，或者均不相同，且第二DCI格式特有的时域资源集合不存在。

在一种可能的设计中，该至少一个时域资源集合包括两个时域资源集合时，这两个时域资源集合包括第一DCI格式对应的第一时域资源集合和第二DCI格式对应的第二时域资源集合。终端设备还可以从网络设备接收第三指示信息，第三指示信息用于指示两个时域资源集合中的一个时域资源集合为第三时域资源集合。本申请实施例，通过第三指示信息来指示时域资源，无需基站和终端之间过多的交互，节省信令开销。

在一种可能的设计中，终端设备可以根据DCI格式的时域重复方式，确定第三时域资源集合的方式一为：终端设备确定时域重复方式为迷你时隙级别重复方式所对应的时域资源集合为所述第三时域资源集合。进一步地，终端设备可以从迷你时隙级别重复方式所对应的时域资源集合中确定时域资源。

在一种可能的设计中，终端设备可以根据DCI格式的时域重复方式，确定第三时域资源集合的方式四为：终端设备确定时域重复方式为时隙级别重复方式所对应的时域资源集合为第三时域资源集合，如果不存在时隙级别重复方式所对应的时域资源集合，则终端设备确定协议预定的时域资源集合为第三时域资源集合。
需要说明的是，终端设备可以选择上述多种方式确定第三时域资源集合，也就是说上述各个方式可以被组合使用。
在一种可能的实施例中，终端设备接收第七指示信息，第七指示信息可以指示第三DCI格式的时域资源集合。例如可以指示具体的时域资源集合，也可以指示具体是两个时域资源集合中的哪一个集合。终端设备根据第七指示信息，确定出第三时域资源集合。本申请实施例，通过第七指示信息来指示时域资源，无需基站和终端之间过多的交互，节省信令开销。
在一种可能的实施例中，终端设备不从网络设备所配置的两个时域资源集合中选择，而是将协议预定的时域资源集合作为第三时域资源集合。基站无需专门向终端指示时域资源确定规则，终端根据协议预定的时域资源集合就能够确定出时域资源，这种方式下无需基站和终端过多的信令交互，能够节省信令开销。

本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面对本申请中所使用到的一些通信名词或术语进行解释说明，该通信名词或术语也作为本申请发明内容的一部分。
一，时隙(slot)：数据调度的一种时域单位，在正常循环前缀下，一个slot有14个符号，在扩展循环前缀下，一个slot有12个符号。
二，高层信令：可以是指高层协议层发出的信令，高层协议层为物理层以上的至少一个协议层。其中，高层协议层具体可以包括以下协议层中的至少一个：媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据会聚协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non access stratum，NAS)。
三，新的DCI格式：例如可以是compact DCI格式，即一个比特数比较少的下行控制信息(downlink control information，DCI)格式，是NR R16中引入的一个新的调度数据的DCI格式，由于比特数比较灵活配置，例如可以配置为比较少的比特数，可以用于调度高可靠性业务的DCI格式。调度上行数据的Compact DCI格式可称为DCI格式0_2(或DCI  format 0_2),调度下行数据的Compact DCI格式可称为DCI格式1_2(或DCI format 1_2)。
四，Fallback DCI格式：适用于在RRC建立之前，或者是RRC重配过程用的DCI格式，调度上行数据的Fallback DCI格式可称为DCI格式0_0(或DCI format 0_0)，调度下行数据的Fallback DCI格式可称为DCI格式1_0(或DCI format 1_0)。Fallback DCI格式中的每个域都和配置信息没有关系，以避免在重配置过程中的模糊。
五，Normal DCI格式：为NR R15中引入的一个进行数据调度的DCI格式，调度上行数据的Normal DCI格式可称为DCI格式0_1(或DCI format 0_1),调度下行数据的Normal DCI格式可称为DCI格式1_1(或DCI format 1_1)。
六，时域资源集合可以为协议预定的时域资源集合，也可以为高层配置的时域资源集合，时域资源集合可以为表格或者其它形式。例如，协议预定的时域资源表格(上行下行分别一个表格)的样式如表1所示。
表1
Figure PCTCN2019116862-appb-000001
其中，S是表示数据信道的开始符号，L是表示数据信道所占的符号个数(从S开始连续的符号的个数)，K2参数(对于上行表格包含K2)或者K0参数(下行表格包含K0)，K2是指示从PDCCH接收到PUSCH发送间隔的slot(时隙)个数。K0是指从PDCCH接收到PDSCH发送间隔的slot(时隙)个数。PDSCH/PUSCH mapping type有两个候选值，分别是Type A和TypeB。其中，Type A表示第一个解调参考信号(demodulation reference signal，DMRS)的位置在slot(时隙)的第3或者第4个符号。TypeB表示第一个DMRS的位置在数据信道开始的第一个符号。
其中，基站通过高层信令(例如RRC信令)给用户配置的时域资源表格(上行下行分别一个表格)的样式如表2所示：
表2
Figure PCTCN2019116862-appb-000002
其中，表2中配置的时域资源表格最多有16行，表2中的SLIV值是将S和L联合编码得到的结果。一个SLIV的值可以唯一的确定一组S和L。K2参数或者K0参数以及PUSCH mapping type的相关解释可以参见上文。
七，基于调度(grant based，GB)的调度方式：是一种数据调度的方法，基站会向终端设备发送控制信息(例如PDCCH),该PDCCH会调度一个下行数据传输(例如PDSCH)，或者是调度一个上行数据(例如PUSCH)传输。换句话说，该PDCCH会指示PDSCH或者PUSCH的时域资源。下面以PUSCH的时域资源指示为例，来说明目前时域资源指示的 过程。
步骤一：基站确定时域资源集合，该时域资源集合可以为协议预定的时域资源集合或者是高层配置的时域资源集合中的一个。(具体协议预定的表格和高层配置的表格的形式可以参照表1和表2)
终端设备针对某个接收到的PDCCH，确定该PDCCH中承载的DCI对应的时域资源集合的方式具体采用下述任一规则：
规则一：如果该PDCCH中承载的DCI是通过小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)或者MCS-C-RNTI，或者临时小区标识符(Temporary Cell Radio Network Temporary Identity，TC-RNTI)，配置调度RNTI(configured scheduling RNTI，CS-RNTI)加扰，并且该物理下行控制信道(physical downlink control channel，PDCCH)是在一个公共搜索空间(CSS)中接收到，该搜索空间关联的控制资源集(cntrol resource set，CORESET)不是CORESET0，(这种情况下，这个DCI一定是fallback DCI,因为只有fallback DCI可以CSS中接收)，那么按下面表3所述的规则确定所述DCI对应的时域资源集合：
表3
Figure PCTCN2019116862-appb-000003
表3的含义是：终端设备确定是否有网络设备没有发送指示信息X，该指示信息可以承载在高层信令中，可以记为：pusch-TimeDomainAllocationList，该指示信息X指示一个终端设备特有的时域资源集合，该时域资源内集合为该终端设备特有的时域资源集合，该终端设备的所有DCI都可以用该特有的时域资源集合：
如果该终端设备特有的时域资源集合为"有"时，也就是网络设备发送指示信息指示该终端设备存在特有的时域资源集合，则该终端设备特有的时域资源集合为DCI对应的时域资源集合；或者
如果该终端设备特有的时域资源集合为"无"时，也就是网络设备未发送指示信息指示该终端设备特有的时域资源集合，则该终端设备确定是否有系统信息指示的时域资源集合：
进一步，如果存在系统信息指示的时域资源集合，即网络设备发送系统信息所指示的时域资源集合，则为DCI对应的时域资源集合；
进一步，如果系统信息未指示时域资源集合，则采用协议默认的时域资源集合为DCI对应的时域资源集合。
规则二：如果该PDCCH中承载的DCI是通过C-RNTI、MCS-C-RNTI、TC-RNTI或CS-RNTI加扰，并且该PDCCH是在一个用户特定搜索空间(终端设备-specific search space,USS)中接收到的(例如该DCI可以是fallback DCI或者是normal DCI)，则按照表3所述的方式确定所述DCI对应的时域资源集合。
步骤二：终端设备接收PDCCH，该PDCCH中携带DCI,DCI中包含X个比特位，指示确定的时域资源集合中的某一行，从而指示出数据信道的开始符号S和长度L。
如果DCI的格式为fallabck DCI，即DCI format 1_0(用于调度下行数据)或者DCI format 0_0(用于调度上行数据)，则X等于4bit，也就是说用4bit来指示时域资源对应的是时域 资源表格中的哪一行。
如果DCI的格式为normal DCI，即DCI format 1_1(用于调度下行数据)或者DCI format 0_1，X的比特数取决于表格的大小，表格是16行就是4bit，表格是8行就是3bit。
八，免调度(grant free，GF)方式：是一种数据调度的方法。也可以称为配置调度方式类型一type 1 configured grant或者是说type1 CG，在该方式下，基站不会给用户发送控制信息PDCCH(这种又称为免授权调度方式，或者配置调度方式)，数据传输所占据的时域资源的位置是通过高层信令配置的。下面具体说明目前GF过程中时域资源指示的过程。
步骤一：基站确定时域资源集合，该时域资源表格可以为协议预定的表格或者是高层配置的表格中的一个(表格内容详见上文，不再赘述)。
具体采用哪个时域资源集合的规则是可以参照在前述"基于调度的调度方式"中的"规则二"的描述，不再赘述。
步骤二：基站向终端设备发送高层信令，该高层信令指示确定的时域资源集合中的某一行，从而指示出数据信道的开始符号S和长度L。
根据上面的方法步骤，用户便可以确定出数据信道的时域资源的开始符号和符号个数。例如，用户可以确定出S＝2，L＝4。则就是说数据信道的开始符号是在符号2，长度是4，如图2A所示。
此外，R15还支持slot(时隙)级的重复。具体方式为：基站还会给用户配置一个聚合因子(aggregationFactorDL)，这个因子我们记为K，K是代表有几个连续的slot中进行数据传输，如果没有配置，则认为是不重复。例如，用户确定数据信道的开始符号是在符号2，长度是4，并且聚合因子是2，含义是说，在连续的2个slot中传输数据，每个slot中的数据的开始符号都是2，长度都是4，如图2B所示。
在NR的R16中，也就是在第16个版本中。时域资源指示的增强点包括：
增强点一：时域重复方式有两种：mini-slot(迷你时隙)的时域重复方式和slot(时隙)的时域重复方式。
第一种：支持mini-slot(迷你时隙)级别的重复(又叫做Rel-16 PUSCH transmission scheme)。
(1)、具体地，基站指示一个时域资源，然后指示一个重复次数R，即从第一个时域资源连续的重复R次得到R个资源。如果其中某一个资源跨slot的边界，则划分为2个资源。
比如指示一个时域资源的开始符号是12，长度是4个符号，指示重复次数为2，也就是第一个资源是符号12到第二个slot的符号1，第二个资源是第二个slot的符号2到符号5。由于第一个资源跨slot边界，可以采用slot边界将其划分为2个资源，也就是最终是3次重复，3次重复占用的资源如图2C。采用这种方式，即使数据在slot的边界，仍然可以进行数据重复，不用等到下一个slot，保证时延和可靠性。
(2)、由于数据可以从任意符号位置开始，该时域重复方式只能支持mapping type B。
(3)、另外，仅支持normal DCI或者是compact DCI调度mini-slot时域重复方式，fallback DCI不支持调度mini-slot时域重复方式。
(4)、重复次数的指示：具体指示mini-slot重复的方式为通过在上述的高层配置的时域资源表格中增加一列，指示重复次数，如表4。
表4
Figure PCTCN2019116862-appb-000004
第二种：支持slot级别的重复(例如Rel-15PUSCH transmission scheme)
具体指示重复次数的方式为在高层配置的表格中增加一列，该列指示重复次数。或者，高层配置的表格还和R15类似，但是不增加一列。通过额外的一个高层信令指示重复的次数。
增强点二：对于GB调度：基站可以针对DCI格式，即normal DCI或者是compact DCI去配置是哪种时域重复方式。比如：normal DCI配置为slot时域重复方式，compact DCI配置为mini-slot时域重复方式。对于GF调度：高层配置时域重复方式。
基于上述分析，目前现有技术针对不同的DCI格式基站可以通过高层信令分别配置不同时域资源表格。假设基站配置了两个时域资源表格，例如normal DCI格式对应的时域资源表格和compact DCI格式的时域资源表格，那么针对GF调度场景，就存在终端设备和基站基于何种原则确定GF场景下对应的时域资源表格，以保证基站和用户理解一致的问题。
为此，如图3所示，本申请实施例提供第一种通信方法流程示意图。该方法可以适用于GF调度场景，可以由终端设备执行，参见图3，该方法包括如下步骤。
步骤301，终端设备确定至少一个时域资源集合，该至少一个时域资源集合中每个时域资源集合对应一个DCI格式。
其中，该至少一个时域资源集合可以是高层信令配置的时域资源集合，也可以是协议预定的时域资源集合。时域资源集合例如可以是前述表1、表2或表4所示的时域资源表，或者可以是其它形式，本申请对此不作限定。
在一种可能的实施例中。该至少一个时域资源集合可以包括一个时域资源集合，也可以包括两个时域资源集合，或者该至少一个时域资源集合包括三个或三个以上时域资源集合。当该至少一个时域资源集合包括两个时域资源集合时，这两个时域资源集合可以分别是第一DCI格式对应的第一时域资源集合和第二DCI格式对应的第二时域资源集合。需要说明的是，下文中第一DCI格式可以理解为normal DCI格式(或者理解为DCI格式0_1或DCI格式1_1)，第二DCI格式可以理解为Compact DCI格式(或者理解为DCI格式0_2或DCI格式1_2)，第三DCI格式可以理解为fallback DCI格式(或者理解为DCI格式0_0或DCI格式1_0)。
步骤302，终端设备根据至少一个时域资源集合，确定免授权调度的第三时域资源集合。
具体来说，终端设备可以根据至少一个时域资源集合的时域重复方式、DCI格式等信息，按照预先约定的规则确定出免授权调度的第三时域资源集合，具体规则可以参见下文。
步骤303，终端设备从第三时域资源集合确定第三时域资源。
步骤304，终端设备在第三时域资源上向网络设备发送上行数据，或者在第三时域资 源上接收下行数据。
下面对图3所示实施例中步骤302确定第三时域资源集合的各种情形进行说明。
情形1，该至少一个时域资源集合为一个时域资源集合，且为第一DCI格式对应的第一时域资源集合。
终端设备确定该第一DCI格式对应的时域资源的一种方式为：
方式一：终端设备接收来自网络设备的指示信息X，该指示信息X指示该第一DCI格式特有的时域资源集合，也就是该第一时域资源集合。该指示信息可以承载在高层信令中，例如该指示信息X可以记为：pusch-TimeDomainAllocationList-ForDCIformat0_1。因为该时域资源集合为该DCI特有的，所有该第一DCI格式调度的数据的时域资源一定是该第一时域资源集合中的一个时域资源。
在一种可能的实施例中，终端设备还可以接收来自网络设备第一指示信息，该第一指示信息用于指示免授权调度的时域重复方式。终端设备根据免授权调度的时域重复方式和至少一个时域资源集合，确定免授权调度的第三时域资源集合。
具体地，在一种可能的实施例中，网络设备除了向终端设备发送第一指示信息，网络设备还可以向终端设备发送第二指示信息，该第二指示信息用于指示第一DCI格式的时域重复方式，以及用于指示所述第二DCI格式的时域重复方式。然后终端设备根据免授权调度的时域重复方式和至少一个时域资源集合，确定免授权调度的第三时域资源集合。具体来说，确定免授权调度的第三时域资源集合的规则为：
规则一：免授权调度的时域重复方式和第一DCI的时域重复方式和第二DCI的重复方式均相同，但是第二DCI格式无特有的时域资源集合，则确定至少一个时域资源集合为所述免授权调度的第三时域资源集合。
其中第二DCI格式没有特有的时域资源集合，也就是说对于第二DCI格式，网络设备没有发送指示信息Y，用于指示该第二DCI格式特有的时域资源集合(即第二时域资源集合)，第二DCI格式特有的时域资源集合是指所有该第二DCI格式调度的数据的时域资源一定是该第二时域资源集合内的一个资源。
规则二：所述免授权调度的时域重复方式、所述第一DCI的时域重复方式和所述第二DCI的重复方式均不相同，且第二DCI格式特有的时域资源集合不存在。此时，确定至少一个时域资源集合为所述免授权调度的第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置了normal DCI格式的时域资源表格，网络设备还向终端设备指示免授权调度的时域重复方式为slot时域重复方式。因网络设备在第二指示信息中指示normal DCI格式为slot时域重复方式，以及Compact DCI格式为slot时域重复方式，所以终端设备可以确定出免授权调度的时域重复方式与normal DCI格式和Compact DCI格式的时域重复方式相同，但是因网络设备并没有为终端设备配置Compact DCI格式对应的时域资源表，所以终端设备确定normal DCI格式的时域资源表为所需要使用的时域资源表。
通过上述情形1所述的方法，可以根据GF的时域重复方式，确定和其时域重复方式相同的DCI格式对应的时域资源集合为GF对应的时域资源集合，首先网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的正常进行；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源有不同的特征，选择重复方式一致的时域资源集合能够保证时域重 复方式能够保证时域资源集合中的所有时域资源都能够满足该时域重复方式的特征，保证正常通信。
需要说明的是以该至少一个时域资源集合为一个时域资源集合、且为第一DCI格式对应的第一时域资源集合、且没有第二DCI格式特有的时域资源集合为例，进行说明，在该至少一个时域资源集合为一个时域资源集合、且为第二DCI格式对应的第二时域资源集合为例、且没有第一DCI格式特有的时域资源集合时，所述方法完全相同，不再赘述。
情形2，该至少一个时域资源集合包括两个时域资源集合时，这两个时域资源集合包括第一DCI格式对应的第一时域资源集合和第二DCI格式对应的第二时域资源集合。
终端设备确定第一DCI格式对应的第一时域资源集合和第二DCI格式对应的时域资源集合的过程可以采用前述情形1中的方式一所述的方法，或者可以用下面的任一方式：
方式二：首先按照方式一的方式确定某一个DCI格式度对应的时域资源集合，如果发现该DCI格式没有特有的时域资源集合，则可以通过表3的方式确定该DCI格式对应的时域资源集合。
方式三：可以通过表3的方式确定该DCI格式对应的时域资源集合，即将表3中的终端设备特有的时域资源集合修改为该DCI格式特有的时域资源集合。
该情形2进一步包括以下情形2.1至情形2.3。
情形2.1，终端设备从至少一个时域资源集合中，选择第二DCI格式对应的第二时域资源集合为第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置了normal DCI格式的时域资源集合和Compact DCI格式的时域资源集合，或者通过前述方式一、方式二或者方式三，确定了normal DCI格式的时域资源集合和Compact DCI格式的时域资源集合，所以终端设备确定Compact DCI格式的时域资源集合为所需要使用的时域资源集合。
或者，终端设备从至少一个时域资源集合中，选择第一DCI格式对应的第一时域资源集合为第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置了normal DCI格式的时域资源集合和Compact DCI格式的时域资源集合，所以终端设备确定normal DCI格式的时域资源集合为所需要使用的时域资源集合。
通过情形2.1所述的方法，规定GF的时域资源集合为某个DCI格式(第一DCI格式或者第二DCI格式)对应的时域资源集合，网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据时域资源，保证通信的可靠性。
情形2.2，在一种可能的实施例中，终端设备还可以从网络设备接收第三指示信息，第三指示信息用于指示两个时域资源集合中的一个时域资源集合为第三时域资源集合。
具体来说，一种情况下，第一指示信息可以指示第一时域资源集合作为第三时域资源集合，终端设备接收到第三指示信息后，根据第三指示信息可以将第一时域资源集合作为第三时域资源集合。另一种情况下，第一指示信息可以指示第二时域资源集合作为第三时域资源集合，终端设备接收到第三指示信息后，根据第三指示信息可以将第二时域资源集合作为第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置了normal DCI格式的时域资源集合和Compact DCI格式的时域资源集合，或者通过前述方式一、方式二或者方式三，确定 normal DCI格式的时域资源集合和Compact DCI格式的时域资源集合，网络设备还向终端设备指示Compact DCI格式的时域资源集合为终端所需要使用的时域资源集合。所以终端设备确定Compact DCI格式的时域资源集合为所需要使用的时域资源集合。
通过情形2.2所述的方法，高层信令为GF指示某个DCI格式(第一DCI格式或者第二DCI格式)对应的时域资源集合，网络设备和终端设备采用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据时域资源，保证通信的可靠性，并且由于GF对应的时域资源集合为网络设备配置的，能够保证配置的时域资源集合尽可能满足GF下的业务需求，保证资源调度的灵活性和可靠性。
可选的在情形2.2中，如果终端设备未收到第一指示信息，也就说网络设备没有发送第一指示信息，则可以采用表3的方式确定第三时域资源集合，也可以采用第一DCI格式对应的时域资源集合，也可以采用第二DCI格式对应的时域资源集合。通过这样的方法，在网络设备未指示第三时域资源集合时，网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据时域资源，保证通信的可靠性。
情形2.3，网络设备除了向终端设备发送第一指示信息，网络设备还可以向终端设备发送第二指示信息，该第二指示信息用于指示第一DCI格式的时域重复方式，以及用于指示所述第二DCI格式的时域重复方式。终端设备根据免授权调度的时域重复方式、第一DCI格式的时域重复方式和/或第二格式的时域重复方式，确定出第三时域资源集合。
方式三，终端设备从第一时域资源集合和第二时域资源集合中，确定时域重复方式与免授权调度的时域重复方式相同的DCI格式所对应的时域资源集合为第三时域资源集合。也就是说，当终端设备确定第一DCI格式的时域重复方式与免授权调度的时域重复方式相同时，则将第一时域资源集合作为第三时域资源集合；当终端设备确定第二DCI格式的时域重复方式与免授权调度的时域重复方式相同时，则将第二时域资源集合作为第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置免授权调度的时域重复方式为slot时域重复方式，网络设备通过RRC信令向终端设备配置了normal DCI格式对应的时域资源集合和Compact DCI格式对应的时域资源集合，或者通过方式一、方式二或者方式三的方式确定了normal DCI格式对应的时域资源集合和Compact DCI格式对应的时域资源集合，网络设备还向终端设备指示normal DCI格式为slot时域重复方式，以及Compact DCI格式为mini slot时域重复方式，所以终端设备可以确定出免授权调度的时域重复方式与normal DCI格式的时域重复方式相同，终端设备确定normal DCI格式对应的时域资源表为所需要使用的时域资源表。
通过方式三所述的方法，可以根据GF的时域重复方式，确定和其时域重复方式相同的DCI格式所对应的时域资源集合为GF对应的时域资源集合。首先，网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证通信的可靠性；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源具有不同的特征，选择重复方式一致的时域资源集合能够保证时域资源集合中的所有时域资源都能够满足该时域重复方式，从而保证正常通信。
方式四，终端设备从第一时域资源集合和第二时域资源集合中，确定时域重复方式与免授权调度的时域重复方式相同的DCI格式所对应的时域资源集合为第三时域资源集合。 当第一DCI格式的时域重复方式和第二DCI格式的时域重复方式均与免授权调度的时域重复方式相同时，终端设备确定第二时域资源集合为第三时域资源集合，或者是终端设备确定第一时域资源集合为第三时域资源集合。或者是说，终端设备确定第二DCI格式对应的时域资源集合为第三时域资源集合，或者是终端设备确定第一DCI格式对应的时域资源集合为第三时域资源集合，或者终端设备根据表3的方式确定第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置免授权调度的时域重复方式为slot时域重复方式，网络设备通过RRC信令向终端设备配置了normal DCI格式的时域资源集合和Compact DCI格式的时域资源集合，或者通过方式一、方式二或者方式三的方式确定normal DCI格式对应的时域资源集合和Compact DCI格式对应的时域资源集合，网络设备还向终端设备指示normal DCI格式为slot时域重复方式，以及Compact DCI格式为slot时域重复方式，所以终端设备可以确定出免授权调度的时域重复方式与normal DCI格式的时域重复方式和Compact DCI格式的时域重复方式均相同，则终端设备确定normal DCI格式对应的时域资源集合为所需要使用的时域资源集合，或者终端设备确定Compact DCI格式对应的时域资源集合为所需要使用的时域资源集合。
通过方式四所述的方法，可以根据GF的时域重复方式，确定和其时域重复方式相同的DCI格式对应的时域资源集合为GF对应的时域资源集合，首先网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的可靠性；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源有不同的特征，选择重复方式一致的时域资源集合能够保证时域资源集合中的所有时域资源都能够满足该时域重复方式，从而保证正常通信；并且在多个时域资源集合能够满足该时域重复方式特性时，通过规定其中一个DCI格式或者其中一个时域资源集合为最终采用的时域资源集合，保证了网络设备和终端设备确定出同一个时域资源集合，保证通信的可靠性。
方式五，终端设备从第一时域资源集合和第二时域资源集合中，确定时域重复方式与免授权调度的时域重复方式相同的DCI格式所对应的时域资源集合为第三时域资源集合。当第一DCI格式的时域重复方式和第二DCI格式的时域重复方式均与免授权调度的时域重复方式不同时，确定第二时域资源集合为第三时域资源集合，或者是终端设备确定第一时域资源集合为第三时域资源集合。或者可以根据表3的方式确定第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置免授权调度的时域重复方式为slot时域重复方式，网络设备通过RRC信令向终端设备配置了normal DCI格式的时域资源表和Compact DCI格式的时域资源表，网络设备还向终端设备指示normal DCI格式为mini slot时域重复方式，以及Compact DCI格式为mini slot时域重复方式，所以终端设备可以确定出免授权调度的时域重复方式与normal DCI格式的时域重复方式和Compact DCI格式的时域重复方式均不同，终端设备确定normal DCI格式对应的时域资源集合为所需要使用的时域资源集合，或者终端设备确定Compact DCI格式对应的时域资源集合为所需要使用的时域资源集合。
通过方式五所述的方法，可以根据GF的时域重复方式，确定和其时域重复方式相同的DCI格式对应的时域资源集合为GF对应的时域资源集合，首先网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的可靠性；其次，由于不同的时域重复方式对应的时域资源集 合中的时域资源有不同的特征，选择重复方式一致的时域资源集合能够保证时域资源集合中的所有时域资源都能够满足该时域重复方式的特征，从而保证正常通信；并且在多个时域资源集合能够满足该时域重复方式特性时，通过规定其中一个DCI格式或者其中一个时域资源集合为最终采用的时域资源集合，保证了网络设备和终端设备确定出同一个时域资源集合，保证通信的可靠性。
方式六，终端设备从第一时域资源集合和第二时域资源集合中，确定时域重复方式与免授权调度的时域重复方式相同的DCI格式所对应的时域资源集合为第三时域资源集合。当第一DCI格式的时域重复方式和第二DCI格式的时域重复方式均与免授权调度的时域重复方式不同时，终端设备根据表3的方式确定第三时域资源集合。确定协议默认的时域资源集合即第四时域资源集合作为第三时域资源集合。或者，终端设备特有的时域资源集合即第四时域资源集合作为第三时域资源集合，或者系统信息指示的时域资源集合即第四时域资源集合作为第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置免授权调度的时域重复方式为slot时域重复方式，网络设备通过RRC信令向终端设备配置了normal DCI格式的时域资源表和Compact DCI格式的时域资源表，网络设备还向终端设备指示normal DCI格式为mini slot时域重复方式，以及Compact DCI格式为mini slot时域重复方式，所以终端设备可以确定出免授权调度的时域重复方式与normal DCI格式的时域重复方式和Compact DCI格式的时域重复方式均不同。因此终端设备确定协议默认的时域资源表格即第四时域资源集合作为第三时域资源集合。或者，终端设备特有的时域资源集合即第四时域资源集合作为第三时域资源集合，或者系统信息指示的时域资源集合即第四时域资源集合作为第三时域资源集合。
通过方式六所述的方法，可以根据GF的时域重复方式，确定和其时域重复方式相同的DCI格式对应的时域资源集合为GF对应的时域资源集合，首先网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的正常进行，保证通信的可靠性；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源有不同的特征，选择重复方式一致的时域资源集合能够保证时域重复方式能够保证时域资源集合中的所有时域资源都能够满足该时域重复方式的特征，保证正常通信；并且在多个时域资源集合都不能够满足该时域重复方式特性时，通过用现有技术中的方式确定一个时域资源集合为最终采用的时域资源集合，降低了实现的复杂度，保证了网络设备和终端设备确定出同一个时域资源集合，保证通信的可靠性。
一种可能的实施例中，图3中的步骤302和步骤503也可以被替换为：终端设备接收指示信息，该指示信息直接指示免授权调度的第三时域资源的开始符号和长度，即直接确定第三时域资源。
如图4所示，本申请实施例提供第二种通信方法流程示意图。该方法可以适用于GF调度场景，该方法可以由网络设备执行，参见图4，该方法包括如下步骤。
步骤401，网络设备确定至少一个时域资源集合，该至少一个时域资源集合中每个时域资源集合对应一个DCI格式。
其中，该至少一个时域资源集合可以是高层信令配置的时域资源集合，也可以是协议预定的时域资源集合。时域资源集合例如可以是前述表1、表2或表4所示的时域资源表， 或者可以是其它形式，本申请对此不作限定。
在一种可能的实施例中，该至少一个时域资源集合可以包括一个时域资源集合，也可以包括两个时域资源集合，或者该至少一个时域资源集合包括三个或三个以上时域资源集合。当该至少一个时域资源集合包括两个时域资源集合时，这两个时域资源集合可以分别是第一DCI格式对应的第一时域资源集合和第二DCI格式对应的第二时域资源集合。需要说明的是，下文中第一DCI格式可以理解为normal DCI格式(或者理解为DCI格式0_1或DCI格式1_1)，第二DCI格式可以理解为Compact DCI格式(或者理解为DCI格式0_2或DCI格式1_2)，第三DCI格式可以理解为fallback DCI格式(或者理解为DCI格式0_0或DCI格式1_0)。
步骤402，网络设备根据至少一个时域资源集合，确定免授权调度的第三时域资源集合。

图4所示实施例中步骤402确定第三时域资源集合的各种情形，可以参见上文图3对应实施例确定第三时域资源集合的各种情形的描述，此处不再赘述。
本申请实施例中，网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的正常进行；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源有不同的特征，选择重复方式一致的时域资源集合能够保证时域重复方式能够保证时域资源集合中的所有时域资源都能够满足该时域重复方式的特征，保证正常通信。
如图5所示，本申请实施例提供第三种通信方法流程示意图。该方法适用于GB调度场景，该方法可以由终端设备执行，参见图5，该方法包括如下步骤。
步骤501，网络设备通过RRC信令向终端设备配置了两个时域资源集合。
步骤502，终端设备接收来自网络设备的两个时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置了两个时域资源集合，分别是normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。或者可以根据前述方式一、方式二或者方式三确定normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。
步骤503，网络设备向终端设备发送第三DCI格式的DCI。
具体来说，网络设备通过物理下行控制信道(physical downlink control channel，PDCCH)承载的DCI调度上行和/或下行数据，则用于传输上行和/或下行数据的传输资源的时域位置根据该PDCCH的时域位置，和该DCI中指示的时域信息联合确定。

步骤506，终端设备从第三时域资源集合确定第三时域资源。
步骤507，终端设备在第三时域资源上发送上行数据，或者在第三时域资源上接收下行数据。
下面对图5所示实施例中步骤505确定第三时域资源集合的各种情形进行说明。
情形3，终端设备除了接收到DCI之外，终端设备还接收第六指示信息，第六指示信息用于指示第一DCI格式的时域重复方式和第二DCI格式的时域重复方式。终端设备可以根据DCI格式的时域重复方式，按照如下方式中的任意一种或多种方式确定第三时域资源集合。
方式七：终端设备确定时域重复方式为迷你时隙级别重复方式所对应的时域资源集合为所述第三时域资源集合。进一步地，终端设备可以从迷你时隙级别重复方式所对应的时域资源集合中确定时域资源。
可选地，如果迷你时隙级别重复方式所对应的时域资源集合中有跨边界的时域资源，则从中选择不跨边界的资源。
示例性地，网络设备通过RRC信令向终端设备配置了两个时域资源集合，分别是normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。或者，终端设备可以同过或者可以根据前述方式亦或者方式二或者方式三确定normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。网络设备向终端设备指示normal DCI格式为slot时域重复方式，以及Compact DCI格式为mini slot时域重复方式，终端设备可以确定出mini slot时域重复方式对应的第二时域资源集合为所需要使用的时域资源集合(即第三时域资源集合)。
通过方式七所述的方法，确定时域重复方式为迷你时隙级重复的DCI格式对应的时域资源集合为所述fallabck DCI对应的时域资源集合，并且只选择其中不跨边界的集合，网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的正常进行，保证通信的可靠性；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源有不同的特征，选择不跨边界的那些行对应的时域资源集合作为fallback DCI对应的时域资源集合，能够保证该时域重复方式对应的时域资源集合中所有时域资源都能够满足不跨边界的特征，保证正常通信。
方式八：终端设备确定时域重复方式为时隙级别重复方式所对应的时域资源集合为所述第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置了两个时域资源集合，分别是normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。或者，终端设备可以根据前述方式一、方式二或者方式三确定normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。网络设备向终端设备指示normal DCI格式为slot时域重复方式，以及Compact DCI格式为mini slot时域重复方式，所以终端设备可以确定出slot时域重复方式对应的第一时域资源表为所需要使用的时域资源表(即第三时域资源集合)。
通过方式八所述的方法，确定时域重复方式为slot级重复的DCI格式对应的时域资源集合为所述fallabck DCI对应的时域资源集合，网络设备和终端设备用相同的规则确定该 时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的正常进行，保证通信的可靠性；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源有不同的特征，选择slot级重复的DCI格式对应的时域资源集合作为fallback DCI对应的时域资源集合，能够保证时域重复方式对应的时域资源集合中的所有时域资源都能够满足不跨边界的特征，保证正常通信。
方式九，终端设备确定时域重复方式为迷你时隙级别重复方式所对应的时域资源集合为所述第三时域资源集合，如果不存在迷你时隙级别重复方式所对应的时域资源集合，则终端设备确定协议预定的时域资源集合为第三时域资源集合。例如，如果没有时隙级重复的DCI格式，即所有DCI格式都没有被配置为迷你时隙级重复，可以按照表3所述的方法确定时域资源集合。
方式十，终端设备确定时域重复方式为时隙级别重复方式所对应的时域资源集合为第三时域资源集合，如果不存在时隙级别重复方式所对应的时域资源集合，则终端设备确定协议预定的时域资源集合为第三时域资源集合。例如，如果没有时隙级重复的DCI格式,即所有DCI格式都没有被配置为迷你时隙级重复，可以按照表3所述的方法确定时域资源集合。
需要说明的是，终端设备可以选择上述多种方式确定第三时域资源集合，例如终端设备首先根据方式七确定时域资源集合，如果未确定出，则根据方式八确定时域资源集合。
情形4，在一种可能的实施例中，终端设备接收第七指示信息，第七指示信息可以指示第三DCI格式的时域资源集合。例如可以指示具体的时域资源集合，也可以指示具体是两个时域资源集合中的哪一个集合。终端设备根据第七指示信息，确定出第三时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置了两个时域资源集合，分别是normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。或者，终端设备可以根据前述方式一、方式二或者方式三确定normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。网络设备通过RRC信令向终端设备发送第七指示信息，第七指示信息用于指示normal DCI格式的第一时域资源集合为终端设备所需要使用的时域资源集合，因此终端设备在收到第七指示信息之后，使用normal DCI格式的第一时域资源集合确定为终端设备所需要使用的时域资源集合，然后在该时域资源集合中的时域资源上收发数据。
通过情形4所述的方法，通过高层信令为fallabck DCI指示为某个DCI格式(第一DCI格式或者第二DCI格式)对应的时域资源集合，网络设备和终端设备采用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据时域资源，保证通信的可靠性，并且由于fallabck DCI对应的时域资源集合为网络设备配置的，能够保证配置的时域资源集合尽可能满足fallabck DCI的需求，保证调度的灵活性和可靠性。
情形5，终端设备不从网络设备所配置的两个时域资源集合中选择，而是将协议预定的时域资源集合作为第三时域资源集合，或者按照表格3所述的方法确定第三时域资源集合。
在一种可能的实施例中，图5中的步骤503和步骤504也可以被替换为：终端设备确定与第三DCI格式的DCI对应的第三时域资源集合中一个资源的开始符号和长度，即直接 确定第三时域资源。
如图6所示，本申请实施例提供第四种通信方法流程示意图。该方法可以适用于GB调度场景，该方法可以由网络设备执行，参见图6，该方法包括如下步骤。
步骤601，网络设备确定两个时域资源集合。
其中，两个时域资源集合包括第一DCI格式的第一时域资源集合和第二DCI格式的第二时域资源集合。
示例性地，网络设备通过RRC信令向终端设备配置了两个时域资源集合，分别是normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。或者可以根据前述方式一、方式二或者方式三确定normal DCI格式的第一时域资源集合和Compact DCI格式的第二时域资源集合。
步骤602，网络设备向终端设备发送第三DCI格式的DCI。
示例性地，网络设备向终端设备发送fallback DCI格式的时域资源表。
步骤603，网络设备确定与第三DCI格式的DCI对应的第三时域资源集合，第三时域资源集合为两个时域集合中的一个。
具体来说，网络设备可以根据两个时域资源集合的时域重复方式、DCI格式等信息，按照预先约定的规则确定出第三时域资源集合，具体规则可以参见下文。
步骤604，网络设备从第三时域资源集合确定第三时域资源。
步骤605，网络设备在第三时域资源上发送下行数据，或者在第三时域资源上接收上行数据。
图6所示实施例中步骤603确定第三时域资源集合的各种情形，可以参见上文图5对应实施例确定第三时域资源集合的各种情形的描述，此处不再赘述。
本申请实施例中，网络设备和终端设备用相同的规则确定该时域资源集合，能够保证双方确定的时域资源集合一致，从而保证确定相同的数据资源，保证通信的正常进行；其次，由于不同的时域重复方式对应的时域资源集合中的时域资源有不同的特征，选择重复方式一致的时域资源集合能够保证时域重复方式能够保证时域资源集合中的所有时域资源都能够满足该时域重复方式的特征，保证正常通信。
从目前R16的相关技术中可以看出normal DCI或者是compact DCI格式可以被配置为时隙级别时域重复方式，也可以被配置为迷你时隙级别时域重复方式，其中不同的时域重复机制的特点不同，比如：(1)对于mini-slot重复，指示的时域资源是可以跨slot边界的，而对于slot重复，不可以跨slot边界；(2)对于mini-slot重复，只能支持mapping type B，而slot重复可以支持type A和B；(3)对于mini-slot重复，只能支持重复次数加在时域资源表中加一列，但是对于slot重复，可以在时域资源表中加一列，或者不加一列而高层配置直接支持重复次数。
假设高层信令为某一个终端设备针对上行只配置一个时域资源表格，那么无论终端设备接收到normal DCI还是compact DCI，终端设备都可以从该时域资源表格随机确定时域资源。但是这个时域资源表中有些行对应的时域资源，对于某些DCI格式存在不适用的情况。比如网络设备向终端设备发送的normal DCI被配置为slot级别重复，那这个时域资源表中的哪些跨边界的行对应的时域资源就不能用。再比如compact DCI被配置为mini slot 级别重复，那么这个时域资源表中的mapping type A的行就不能用。因此就需要有一个机制可以保证网络设备所下发的DCI的DCI格式对应的时域资源表能和该DCI格式配置的时域重复方式相对应。为此，如图7所示，本申请实施例提供第五种通信方法流程示意图。该方法适用于GB调度场景，该方法可以由终端设备执行，参见图7，该方法包括如下步骤。
步骤701，网络设备向终端设备发送第一DCI格式的DCI。
示例性地，网络设备向终端设备发送normal DCI格式的DCI，或者是compact DCI格式的DCI。
步骤702，终端设备接收来自网络设备的DCI。
步骤703，终端设备根据DCI的第一DCI格式，从第一时域资源集合中确定第二时域资源集合。
具体来说，终端设备可以根据第一时域资源集合的时域重复方式、第一DCI格式的DCI的时域重复方式等信息，按照预先约定的规则确定出第二时域资源集合，具体规则可以参见下文。
步骤704，终端设备从第二时域资源集合中确定第二时域资源；
步骤705，终端设备在第二时域资源上接收下行数据，或在第二时域资源上发送上行数据。
下面对图7所示实施例中步骤704确定第二时域资源集合的各种情形进行说明。
示例1，在一种可能的实施例中，终端设备还可以从网络设备接收第四指示信息，第四指示信息用于指示DCI的时域重复方式。终端设备可以根据DCI的第一DCI格式和DCI的时域重复方式，从第一时域资源集合中确定第二时域资源集合。换句话说，终端设备可以根据DCI格式是normal DCI格式还是compact DCI格式，以及是mini slot级别时域重复方式还是slot级别时域重复方式，终端设备可以按照以下几种方式中的任意一种方式或多种方式，从第一时域资源集合中确定出满足条件的第二时域资源集合。
方式十一：在网络设备下发的DCI的第一DCI格式为normal DCI格式或compact DCI格式(即为DCI格式0_1、DCI格式0_2、DCI格式1_1或DCI格式1_2)时，且第四指示信息指示DCI的时域重复方式为时隙级别重复方式时，终端设备从第一时域资源集合中确定不跨时隙边界的时域资源为第二时域资源。
示例性地，如图2C中，如果第一时域资源集合中某一行的开始符号是12，长度是4个符号，指示重复次数为2时，那么可见该时域资源是跨边界的，则终端设备不选择这个时域资源，相反地，如果该时域资源没有跨边界，则终端设备选择其作为第二时域资源。
方式十二，在网络设备下发的DCI的第一DCI格式为normal DCI格式或compact DCI格式(即为DCI格式0_1、DCI格式0_2、DCI格式1_1或DCI格式1_2)时，且第四指示信息指示DCI的时域重复方式为时隙级别重复方式时，终端设备从第一时域资源集合中确定不包括重复次数信息的时域资源为第二时域资源。
例如，第一时域资源集合为表5所示的时域资源表。终端设备确定表5中重复次数R不为0的时域资源为第二时域资源，即终端设备不选择表1中行号1对应的时域资源，而选择行号2、行号3或者行号16对应的时域资源为第二时域资源。
表5
Figure PCTCN2019116862-appb-000005
方式十三，在网络设备下发的DCI的第一DCI格式为DCI格式0_1、DCI格式0_2、DCI格式1_1、DCI格式1_2中的任意一种，且DCI的时域重复方式为迷你时隙级别重复方式时，终端设备从第一时域资源集合中确定映射类型为mapping type B的时域资源为第二时域资源，或者终端设备从第一时域资源集合中确定包括重复次数信息的时域资源为第二时域资源。
例如，第一时域资源集合为表5所示的时域资源表。终端设备确定表5中mapping type B为Type B的时域资源为第二时域资源，即终端设备不选择表1中行号1对应的时域资源，而选择行号2、行号3或者行号16对应的时域资源为第二时域资源。
再比如，终端设备确定表5中重复次数R不为0的时域资源为第二时域资源，或者终端设备确定表5中重复次数R存在的时域资源为第二时域资源，即终端设备不选择表1中行号1对应的时域资源，而选择行号2、行号3或者行号16对应的时域资源为第二时域资源。
方式十四，在网络设备下发的DCI的第一DCI格式为fallback DCI(即为DCI格式0_0或DCI格式1_0)时，终端设备从第一时域资源集合中确定不跨时隙边界的时域资源为第二时域资源。
示例性地，网络设备向终端设备下发fallback DCI格式的DCI，终端设备不选择图2C所示跨边界的时域资源，相反地，终端设备选择其它不跨边界的时域资源作为第二时域资源。
方式十五，在网络设备下发的DCI的第一DCI格式为fallback DCI(即为DCI格式0_0或DCI格式1_0)时，终端设备从第一时域资源集合中确定不包括重复次数信息的时域资源为第二时域资源。
示例性地，网络设备向终端设备下发fallback DCI格式的DCI，终端设备确定表5中重复次数R不为0的时域资源为第二时域资源，即终端设备不选择表1中行号1对应的时域资源，而选择行号2、行号3或者行号16对应的时域资源为第二时域资源。
方式十六，在网络设备下发的DCI的第一DCI格式为fallback DCI(即为DCI格式0_0或DCI格式1_0)时，终端设备根据表3的方式确定第二时域资源，第二时域资源为根据表3确定的时域资源集合中包含的所有时域资源。
需要说明的是，针对上述方式十三至方式十六，在一种可能的实施例中，在确定DCI的第一DCI格式为fallback DCI格式的DCI时，终端设备还需要判断确定该DCI是否满足第一条件，若满足第一条件，则按照方式十三至方式十六中对应的方法确定第二时域资源。
其中，第一条件为：DCI的加扰方式为C-RNTI、MCS-C-RNTI、TC-RNTI、CS-RNTI 中的任意一个，且DCI对应的PDCCH是在第一搜索空间接收到的；其中，第一搜索空间为公共搜索空间(CSS)，所述CSS关联的控制资源集合CORESET不是CORESET0；或者，所述第一搜索空间为终端设备特定的搜索空间(USS)。
如图8所示，本申请实施例提供第六种通信方法流程示意图。该方法可以适用于GB调度场景，该方法可以由网络设备执行，参见图8，该方法包括如下步骤。
步骤801，网络设备向终端设备发送DCI，所述DCI的格式为第一DCI格式。
示例性地，网络设备向终端设备发送normal DCI格式的DCI，或者是compact DCI格式的DCI。
步骤802，网络设备根据DCI的第一DCI格式，从第一时域资源集合中确定第二时域资源集合。
具体来说，网络设备可以根据第一时域资源集合的时域重复方式、第一DCI格式的DCI的时域重复方式等信息，按照预先约定的规则确定出第二时域资源集合，具体规则可以参见下文。
步骤803，网络设备从第二时域资源集合中确定第二时域资源；
步骤804，网络设备在第二时域资源上接收上行数据，或在第二时域资源上发送上行数据。
图8所示实施例中步骤803确定第三时域资源集合的各种情形可以参见上文图7的描述，此处不再赘述。
本申请实施例中，在高层配置了一个时域资源表格时，对于normal DCI格式和compact DCI格式，分别从该时域资源表格中选择满足该DCI格式对应的时域重复方式的行进行指示，能够减小该DCI格式中的比特数，降低DCI的比特数也就保证了DCI的可靠性。比如，时域资源表格中有64行，其中有32行是跨边界的，32行是不跨边界的，那么某一个DCI格式如果只支持slot重复，那么它可以从64行中选择32行不跨边界的那些行，即该DCI中的比特数为5bit，而不用占用6bit去指示64个值。对于fallback DCI来说，由于就只有一个表格，此时可以直接用该表格避免了模糊。由于fallback DCI也不支持mini-slot重复，还需要从该表格中选择出满足slot重复的那些SLIV；或者及时配置了时域资源表格，对于fallback DCI，为了降低复杂度，直接选择协议预定的时域资源表格。所以可以保证基站和终端设备理解一致的问题，保证通信的可靠性。
