Description

混合自动重传反馈码本的确定方法、装置及设备 技术领域
本申请实施例涉及移动通信技术领域，具体涉及一种混合自动重传反馈码本的确定方法、装置及设备。
背景技术
为了提高频谱效率，同时保证第4代移动通信网络(the 4th generation mobile communication technology，4G)到第5代移动通信网络(the 5th generation mobile communication technology，5G)的平滑过渡，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)提出了长期演进技术(Long Term Evolution，LTE)系统和新空口(New Radio，NR)系统之间的动态频谱共享(Dynamic Spectrum Sharing，DSS)技术。DSS是指在同一频段内为LTE系统和NR系统动态、灵活的分配频谱资源。
实际应用中，为了避免NR系统对LTE系统的干扰，在LTE和NR共享的频谱资源中，NR传输无法使用LTE小区参考信号(Cell Reference Signal，CRS)和LTE物理下行控制信道(Physical Downlink Control CHannel，PDCCH)的资源。因此，在DSS中，NR PDCCH的容量将会受到影响。
为了解决DSS中PDCCH的资源使用受限问题，在NR的版本17(Release 17，R17)中支持一个下行控制信息(Downlink Control Information，DCI)调度多个下行信息，这里，多个下行信息位于不同的服务小区(也可以称为载波)中。例如，在主小区(Primary Cell，PCell)，或者辅小区(Secondary Cell，SCell)中传输的一个DCI，可以同时调度PCell的物理下行共享信道(Physical Downlink Share CHannel，PDSCH)和SCell的PDSCH。然而，在同一个DCI调度的多个下行信息的场景中，如何确定多个下行信息对应的混合自动重传(Hybrid Automatic Repeat ReQuest，HARQ)反馈码本，目前并没有明确的方法。
发明内容

第二处理单元，配置为基于所述第一DAI，确定第一HARQ反馈码本。
第五方面，本申请实施例提供一种终端设备，包括：处理器和存储器，该存储器用于存储计算机程序，所述处理器用于调用并运行所述存储器中存储的计算机程序，执行上述第一方面所述的HARQ反馈码本的确定方法。
第六方面，本申请实施例提供一种网络设备，包括：处理器和存储器，该存储器用于存储计算机程序，所述处理器用于调用并运行所述存储器中存储的计算机程序，执行上述第二方面所述的HARQ反馈码本的确定方法。

为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
在介绍本申请之前，下面对本申请涉及的相关知识进行介绍。
HARQ反馈码本：终端设备可以将网络设备传输的多个下行信息的接收结果，即HARQ应答(HARQ-ACK)信息，在一个上行控制信息(Uplink Control Information，UCI)中反馈给网络设备。其中，所述下行信息可以包括以下信息中的一个或者多个：PDSCH、半静态调度(Semi-Persistent Scheduling，SPS)PDSCH释放指示信息、SCell休眠指示信息。本申请实施例对此不做限定。所述多个下行信息可以来自不同的下行时间单元和/或MIMO下的不同码字和/或载波聚合下的不同载波。
目前，通信系统可以支持两种不同的HARQ反馈码本，一种是半静态HARQ反馈码本(也被称为Type-1 HARQ-ACK反馈码本)，另一种是动态HARQ反馈码本(也被称为Type-2 HARQ-ACK反馈码本)。
其中，动态HARQ反馈码本主要降低反馈信息的信令开销，即在PDCCH监测机会集合内(The set of PDCCH monitoring occasions)，根据DCI实际调度的PDSCH、SPS PDSCH释放指示、以及SCell休眠指示的数量确定肯定/否定(ACK/NACK)信息的比特数。
特别地，为了应对DCI漏检的问题，网络设备可以为每个DCI配置一个DAI信息。
在网络设备只配置1个载波传输下行信息的场景中，各DCI中携带一个DAI信息，该DAI也可以称为计数DCI(Counter DCI，C-DAI)。
示例性的，参考图2A所示的一种相关技术中的数据传输示意图一，在该数据传输场景中，网络设备配置一个服务小区传输下行信息(即图2A中的服务小区1)、以及基于传输块(Transmission Block，TB)的传输方式，且每个DCI只调度1个码本。如图2A所示，网络设备向终端设备发送DCI 1～DCI 4。其中，DCI 1用于调度PDSCH 1，其对应的DAI的取值为1。DCI 2用于调度PDSCH 2，其对应的DAI的取值为2。DCI 3用于调度PDSCH 3，其对应的DAI的取值为3。DCI 4用于调度PDSCH 4，其对应的DAI的取值为4。若终端设备漏检调度PDSCH 3的DCI 3，导致终端设备未接收到PDSCH 3。终端设备接收到调度PDSCH 4的DCI 4，且对应的DAI的取值为4，则终端设备可以根据接收到的DCI 1、DCI 2和DCI 4中的DCI取值，判断出漏检PDSCH 3，则将反馈4比特HARQ-ACK信息给网络侧。
在网络设备配置多个载波传输下行信息的场景中，DAI可以包括C-DAI和总数DCI(Total DAI，T-DCI)。其中，C-DAI表示到当前服务小区和当前PDCCH监测机会，DCI关联的PDSCH、SPS PDSCH释放指示信息或者SCell休眠指示信息的累计个数。T-DAI表示到当前PDCCH监测机会，所有服务小区上的DCI关联的PDSCH接收、SPS PDSCH释放信息或者SCell休眠指示信息的累计个数。
示例性的，DCI中包含的C-DAI为2比特。网络设备配置的C-DAI为1～4的循环计数值，也就是说C-DAI的取值是在1,2,3,4之间循环，第一次出现的“1”计数为1，第二次出现的“1”实际计 数为5。基于此，动态HARQ反馈码本的构建过程如下：
首先，初始化第一临时值为0；初始化j＝0，其中j表示C-DAI达到最大值的次数。
其次，按照服务小区的索引增加然后PDCCH监测机会的索引增加的顺序，遍历所有的PDCCH监测机会和服务小区。
具体地，在当前的PDCCH监测机会和当前服务小区，若终端设备接收到PDSCH或者SPS PDSCH释放信息或者SCell休眠指示信息，则：
判断DCI中携带的C-DAI和第一临时值的大小关系；
如果C-DAI的取值小于等于第一临时值，则将j+1，并更新第一临时值为C-DAI的取值；
否则，更新第一临时值，为C-DAI的取值。
如果一个DCI能够调度的最大码字数为1，则终端设备在HARQ反馈码本的第4*j+C-DAI-1的比特位上，填充DCI调度的数据的HARQ-ACK信息；
如果一个DCI能够调度的最大码字数为2，且终端设备被配置了HARQ-ACK空间捆绑，即harq-ACK-SpatialBundlingPUCCH，则终端设备在第4*j+C-DAI-1的比特位上，填充当前服务小区中DCI调度的两个TB的HARQ-ACK信息逻辑与后的取值；
如果一个DCI能够调度的最大码字数为2，且终端设备未被配置了HARQ-ACK空间捆绑，则终端设备在第2*4*j+2*(C-DAI-1)的比特位上，填充DCI调度的第一个TB的HARQ-ACK信息，在第2*4*j+2*(C-DAI-1)+1的比特位上填DCI调度的第二个TB的HARQ-ACK信息。
最后，终端设备可以根据PDCCH监听机会集合内接收到的最后一个DAI的取值，确定HARQ反馈码本的总比特数，记为O ACK，若在上述执行过程中，在HARQ反馈码本的某些比特位置上未填充相应的HARQ-ACK信息，则在这些比特位置上填充NACK。
R17中支持一个DCI调度多个服务小区中传输的下行信息。参考图2B所示的一种相关技术中的数据传输示意图一，网络设备向终端设备发送DCI 1～DCI 4。其中，DCI 1用于调度在服务小区1中传输的PDSCH 1。DCI 2用于调度在服务小区1传输的PDSCH 2，其对应的DAI的取值为2。DCI 3用于调度在服务小区1传输的PDSCH 3，以及在服务小区2传输的PDSCH4。DCI 4用于调度在服务小区1中传输的PDSCH 5。
相关技术中，当网络设备在PDCCH监测机会集合中既传输调度一个下行信息的DCI，又传输调度多个下行信息的DCI时，如果某个DCI漏检，终端设备将无法得知漏检的DCI调度的是一个下行信息的DCI还是多个下行信息的DCI。进而，终端设备无法确定对应位置应该包含1比特HARQ-ACK信息还是多个比特HARQ-ACK信息，也就是说，终端设备是无法区分下图2A和图2B中漏检的DCI 3是调度一个下行信息的DCI，还是调度多个下行信息的DCI。这将会导致网络设备和终端设备对HARQ反馈码本携带的信息理解不一致的问题。例如，在图2A中终端设备漏检的是调度一个PDSCH的DCI 3，因此终端设备构建的HARQ反馈码本需要包含4比特的信息；而在图2B中，终端设备漏检的是调度两个PDSCH的DCI 3，因此终端设备构建的HARQ反馈码本需要包含5比特的信息。
由此可见，当DCI调度两个或两个以上服务小区中的下行信息时，即一个DCI调度多个服务小区传输的下行信息时，如何确定HARQ反馈码本是本申请亟待解决的技术问题。
为了解决上述技术问题，本申请提供一种HARQ反馈码本的确定方法、装置及设备。为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图3为本申请一实施例提供的HARQ反馈码本的确定方法的流程示意图，如图3所示，该方法包括以下步骤：
步骤310、网络设备发送第一DCI；第一DCI中携带第一DAI，
步骤320、终端设备接收第一DCI；第一DCI中携带第一DAI；
其中，第一DAI的取值为第一累计数目，或者，第一累计数目和第一调整量之和；第一累计数目为到当前PDCCH监测机会和当前服务小区为止，DCI关联的下行信息的累计个数；第一调整量与至少一个目标DCI关联的下行信息相关；至少一个目标DCI包括当前PDCCH监测机会中，到当前服务小区为止，网络设备传输的用于调度多个下行信息的DCI。
步骤330、终端设备基于第一DAI，确定第一HARQ反馈码本。
步骤340、网络设备基于第一DAI，确定第一HARQ反馈码本。
本申请实施例中，第一DCI承载在PDCCH中传输。这里，终端设备可以在PDCCH监测机会 集合中检测网络设备发送的第一DCI。也就是说，第一DCI可以是终端设备在PDCCH监测机会集合中的任意一个PDCCH监听机会中接收。
在一些实施例中，第一DCI可以是用于调度一个下行信息的DCI，也可以是调度多个下行信息的DCI，本申请实施例对此不做限定。
本申请实施例中，第一DCI中可以携带第一DAI。第一DAI用于累计PDCCH监测机会集合中传输的下行信息的个数。
在一些实施例中，第一DAI可以是计数器型的DAI，即C-DAI。
在一些实施例中，第一DAI的取值可以是第一累计数目，或者，第一累计数目和第一调整量之和。
其中，第一累计数目为到当前PDCCH监测机会和当前服务小区为止，网络设备传输的DCI关联的下行信息的累计个数。
这里，当前PDCCH监测机会，是指接收第一DCI的PDCCH监测机会。当前服务小区，是指传输第一DCI的服务小区。
可以理解的是，第一累计数目，是在PDCCH监测机会集合中，按照先服务小区的索引值增加然后PDCCH监测机会的索引值增加的顺序进行统计，到当前传输第一DCI的PDCCH监测机会和当前传输第一DCI的服务小区为止，网络设备传输的所有DCI调度的下行信息累计个数。
在一些实施例中，第一调整量，可以与至少一个目标DCI关联的下行信息相关；至少一个目标DCI包括在当前传输第一DCI的PDCCH监测机会集合中，到当前服务小区为止，网络设备传输的用于调度多个下行信息的所有DCI。
也就是说，目标DCI是指用于调度多个下行信息的DCI。
需要说明的是，至少一个目标DCI可以包括第一DCI，也可以不包括第一DCI。若第一DCI可以调度多个下行信息，则至少一个目标DCI中包括所述第一DCI。若第一DCI仅调度一个下行信息，则至少一个目标DCI中不包括所述第一DCI。
可以理解的是，第一调整量可以根据至少一个目标DCI所关联的下行信息的个数确定。也就是说，第一调整量可以对目标DCI调度的多个下行信息进行计数，从而保证终端设备和网络设备对调度的下行信息的个数理解一致。
在一些实施例中，下行信息可以包括以下信息中的至少一个：
PDSCH、SPS PDSCH释放指示信息、SCell休眠指示信息。
进一步地，终端设备可以根据第一DAI，确定第一DCI调度的下行信息对应的HARQ-ACK信息在第一HARQ反馈码本中的比特位置，并在确定的比特位置上填充该第一DCI调度的下行信息对应的HARQ-ACK信息。
而网络设备可以根据第一DAI，确定第一DCI调度的下行信息对应的HARQ-ACK信息，位于第一HARQ反馈码中的哪些比特位中。
需要说明的是，第一HARQ反馈码本是动态HARQ反馈码本，即Type-2 HARQ-ACK反馈码本。
可选地，本申请实施例提供的方法还可以包括步骤350和360。
步骤350、终端设备向网络设备发送第一HARQ反馈码本。
步骤360、网络设备接收终端设备发送的第一HARQ反馈码本。
这样，网络设备可以根据第一HARQ反馈码本中包含的信息，确定在PDCCH监测机会集合中传输的下行信息的接收结果，并进行相应的处理。
由此可见，第一DCI中携带的第一DAI不仅可以累计截止到当前PDCCH监测机会和当前服务小区为止的DCI调度的下行信息个数，还可以累计用于调度多个下行信息的目标DCI关联的下行信息个数。这样，终端设备根据第一DAI的取值确定出的第一HARQ反馈码本中，可以包括至少一个目标DCI调度的多个下行信息分别对应的HARQ-ACK信息，如此，提升了信息传输的效率。。
在一些实施例中，若在当前PDCCH监测机会中，到当前服务小区为止，存在网络设备传输的至少一个目标DCI，且至少一个目标DCI调度的多个下行信息所在的服务小区中，存在索引值比当前服务小区的索引值大的服务小区，则第一DAI的取值为第一累计数目和第一调整量之和。
可以理解的是，在当前传输第一DCI的PDCCH监测机会中，按照服务小区的索引值增加的顺序遍历到当前服务小区，若存在网络设备传输的至少一个目标DCI(即调度多个下行信息的DCI)，且当前服务小区并不是至少一个目标DCI调度的下行信息所在的最大索引值的服务小区，则第一DAI的取值为第一累计数目和第一调整量之和。
在一些实施例中，第一调整量为至少一个目标DCI调度的多个下行信息所在的服务小区中，索 引值比当前服务小区的索引值大的服务小区的下行信息的个数。
可以理解的是，网络设备可以在一个PDCCH监测机会中传输多个DCI，若网络设备传输的多个DCI中包含至少一个目标DCI(即调度多个下行信息的DCI)时，第一调整量可以是至少一个目标DCI调度的多个下行信息所在的服务小区中，索引值比当前服务小区的索引值大的服务小区上传输的所有下行信息的个数。
在一些实施例中，若在当前PDCCH监测机会中，到当前服务小区为止，不存在索引值比当前服务小区的索引值大的服务小区的下行信息，则第一DAI的取值为第一累计数目。
其中，在当前PDCCH监测机会中，到当前服务小区为止，不存在索引值比当前服务小区的索引值大的服务小区的下行信息，可以包括以下任意一种情况：
在当前PDCCH监测机会中，到当前服务小区为止，网络设备未传输目标DCI；
在当前PDCCH监测机会中，到当前服务小区为止，网络设备传输至少一个目标DCI，但是至少一个目标DCI调度的多个下行信息所在的服务小区的索引值，均小于当前服务小区的索引值，即当前服务小区为至少一个目标DCI调度的下行信息所在的最大索引值的服务小区。
在一示例中，参考图4A示的一种数据传输示意图一，PDCCH监测机会集合仅包括一个PDCCH监测机会。网络设备可以在服务小区1至服务小区4传输下行信息。
其中，网络设备可以通过服务小区1传输DCI a，DCI a可以调度服务小区1的PDSCH 1和服务小区3中的PDSCH 3。网络设备可以通过服务小区2传输DCI b，DCI b可以调度服务小区2的PDSCH 2和服务小区4中的PDSCH 4。
这里，确定DCI a对应的DAI时，可以按照服务小区的索引值增加的顺序统计。在当前PDCCH监测机会中，截止到服务小区1，存在一个用于调度多个下行信息的DCI，即DCI a。并且，DCI a调度的PDSCH所在的最大索引值的服务小区为服务小区3，其索引值大于当前服务小区1的索引值。因此，DCI a中携带的DAI的取值应为第一累计数目+第一调整量。其中，第一累计数目为1，第一调整量为服务小区3的下行信息个数，即第一调整量为1。因此，DCI a对应的DAI取值为2。
进一步地，确定DCI b对应的DAI时，可以确定在当前PDCCH监测机会中，截止到传输DCI b的当前服务小区2，存在两个调度多个下行信息的DCI，即DCI a和DCI b。并且，DCI a和DCI b调度的多个PDSCH所在的最大索引值的服务小区为服务小区4，其索引值大于当前服务小区2的索引值。因此，DCI b中携带的DAI的取值应为第一累计数目+第一调整量。其中，第一累计数目为服务小区1和服务小区2传输的PDSCH的个数，即第一累计数目为2。第一调整量为服务小区3和服务小区4的PDSCH个数，即第一调整量为2。因此，DCI b对应的DAI取值为4。
在另一示例中，参考图4B所示的一种数据传输示意图二，网络设备可以通过服务小区1传输DCI a，DCI a可以调度服务小区1的PDSCH 1和服务小区3中的PDSCH 3。网络设备可以通过服务小区2传输DCI b，DCI b可以调度服务小区2的PDSCH 2。网络设备还可以通过服务小区4传输DCI c，DCI c可以调度服务小区4的PDSCH 4。
这里，确定DCI a对应的DAI时，可以按照服务小区的索引值增加的顺序统计。在当前PDCCH监测机会中，截止到服务小区1，存在一个用于调度多个下行信息的DCI，即DCI a。并且，DCI a调度的PDSCH 3所在的最大索引值的服务小区为服务小区3，其索引值大于当前服务小区1的索引值。因此，DCI a中携带的DAI的取值应为第一累计数目+第一调整量。其中，第一累计数目为1，第一调整量为服务小区3的下行信息个数，即第一调整量为1。因此，DCI a对应的DAI取值为2。
在确定DCI b对应的DAI时，可以确定在当前PDCCH监测机会中，截止到传输DCI b的当前服务小区2，存在一个调度多个下行信息的DCI，即DCI a。并且，DCI a调度的PDSCH所在的最大索引值的服务小区为服务小区3，其索引值大于当前服务小区2的索引值。因此，DCI b中携带的DAI的取值应为第一累计数目+第一调整量。其中，第一累计数目为2，第一调整量为服务小区3的下行信息个数，即第一调整量为1。因此，DCI b对应的DAI取值为3。
在确定DCI c对应的DAI时，可以确定在当前PDCCH监测机会中，截止到传输DCI c的当前服务小区4，存在一个调度多个下行信息的DCI，即DCI a。其中，DCI a调度的PDSCH所在的最大索引值的服务小区为服务小区3，其索引值小于当前服务小区4的索引值。因此，DCI c中携带的DAI的取值应为第一累计数目。其中，第一累计数目为4，即服务小区1至服务小区4中传输的PDSCH累计个数。因此，DCI c对应的DAI取值为4。
综上所述，本申请实施例提供的反馈码本确定方法中，第一DAI的取值并未改变下行信息的计数本质，只在累计数量上做修正，可以避免DCI漏检导致网络设备和终端设备对HARQ-ACK比特数理解不一致的问题。
在一些实施例中，第一DCI的格式为第一DCI格式；第一DCI格式表示第一DCI用于调度N个下行信息；N为大于或等于2的整数；
或者，
第一DCI的格式为第二DCI格式；第二DCI格式表示所述第一DCI用于调度一个下行信息。
可以理解的是，终端设备接收到的第一DCI可以是用于调度一个下行信息的DCI，也可以是用于调度多个下行信息的DCI。
在一些实施中，可以通过DCI格式，来指示当前传输的DCI是调度一个下行信息的DCI，还是调度多个下行信息的DCI。
其中，当某个DCI的格式为第一DCI格式，则确定该DCI是调度多个下行信息的DCI。当某个DCI的格式为第二DCI格式，则确定该DCI是调度一个下行信息的DCI。这里，第二DCI格式可以是DCI格式1_0(即DCI format 1_0)，或者，DCI format 1_1，或者DCI format 1_2中的任意一种，本申请实施例对此不做限定。
在一些实施例中，在第一DCI为能够调度多个下行信息的第一DCI格式的情况下，第一DCI调度的多个下行信息对应的DAI值相同，或者，第一DCI调度的多个下行信息共享同一个DAI指示域。
示例性的，参考图4A所示，DCI a调度PDSCH 1和PDSCH 3。因此，PDSCH 1和PDSCH 3对应的DAI值均为2。
本申请实施例中，同一个DCI调度的多个下行信息，共享同一个DAI，能够降低DCI信令开销。
本申请实施例中，终端设备接收到的DCI的格式不同，则确定该DCI的HARQ反馈码本的方式也就不同。
在一些实施例中，若第一DCI为调度一个下行信息的第二DCI格式，则终端设备和网络设备可以按照上述相关技术中的方式，确定第一DCI调度的下行信息在第一HARQ反馈码本中的位置，并在确定的位置中填充该下行信息对应的HARQ-ACK信息。
在一些实施例中，若第一DCI为调度N个下行信息的第一DCI格式，则终端设备和网络设备可以通过以下两种方式构建包含该N个下行信息对应的HARQ-ACK信息的第一HARQ反馈码本。
方式一、
在终端设备满足第一条件的情况下，终端设备基于第一DAI，确定第一HARQ反馈码本，可以通过以下方式实现：
终端设备在第一HARQ反馈码本中的第(T D*j+第一DAI-N)的比特位，至第(T D*j+第一DAI-1)的比特位，分别填充第一DCI调度的N个下行信息对应的HARQ-ACK信息；
其中，N个下行信息对应的HARQ-ACK信息在第一HARQ反馈码本的排列顺序，与N个下行信息所在的服务小区的索引值相关；T D根据第一DAI在所述第一DCI中占用的比特数确定，j为到当前PDCCH监测时机和当前服务小区为止，DAI为最大值的出现次数。
可以理解的是，终端设备可以根据第一DAI的值，在第一HARQ反馈码本中确定N个比特位，分别填充第一DCI调度的N个下行信息对应的HARQ-ACK信息。
其中，终端设备可以按照N个下行信息所在服务小区的索引值的大小顺序，在第一HARQ反馈码本中填充N个下行信息分别对应的HARQ-ACK信息。
本申请实施例中，为了降低DCI的信令开销，DCI中携带的DAI可以是循环计数值。即DAI的取值在1～T D之间循环。其中，T D为2 M，M为DAI在DCI中占用的比特数。
另外，j为按照先服务小区的索引值增加然后PDCCH监测机会的索引值增加的顺序进行统计时，截止到当前PDCCH监测时机和当前服务小区为止，DAI取值为最大值的出现次数。示例性的，假设DAI在DCI中占用的比特数为2比特，即每个DCI中携带的DAI的取值在1～4之间循环。在初始情况下，j的取值为0。终端可以进行第一轮循环计数，DAI的取值分别为1、2、3、4。当检测到DAI第一次出现最大值“4”时，设置j取值为1，并继续第二轮循环计数，DAI的取值分别为1、2、3、4。在第二轮循环计数时，“DAI＝1”(即第二次出现“DAI＝1”)，表征DAI的取值为5(即4*1+1)，“DAI＝2”表征DAI的取值为6(即4*1+2)，“DAI＝3”表征DAI的取值为7(4*1+3)，“DAI＝4”表征DAI的取值为8(4*1+4)。进一步，当判断DAI第二次出现最大值“4”时，设置j取值为2，并继续第三轮循环计数，直至统计到最后一个DCI中的DAI。也就是说，j为DAI最大值的出现次数。
在一些实施例中，第一条件可以包括以下至少之一：
终端设备被配置有第一参数，且终端设备在N个下行信息所在的服务小区中的至少一个服务小 区上被配置的第二参数的取值为2；
终端设备在N个下行信息所在的服务小区中每个服务小区上被配置的第二参数的取值为1；
其中，第一参数用于使能HARQ-ACK空间捆绑，第二参数用于指示一个DCI能够调度的最大的码字数。
在一种可能的实现方式中，若所有服务小区中传输的DCI均只调度1个码字，即终端设备在所有服务小区中接收一个TB，则终端设备可以在第一HARQ反馈码本中的第(T D*j+第一DAI-N)的比特位，至第(T D*j+第一DAI-1)的比特位，分别填充第一DCI调度的N个PDSCH对应的HARQ-ACK信息。
示例性的，若第一DCI调度两个服务小区中传输的下行信息，且每个服务小区中传输的DCI均只调度1个码字，则终端设备可以在第(T D*j+第一DAI-2)的比特位上填充上述两个服务小区中，索引值较大的服务小区对应的HARQ-ACK信息。另外，终端设备可以在第(T D*j+第一DAI-1)的比特位上填充上述两个服务小区中，索引值较大的服务小区对应的HARQ-ACK信息。
在另一种可能的实现方式中，若终端设备被配置了HARQ-ACK空间捆绑(即终端设备被配置了harq-ACK-SpatialBundlingPUCCH)，且终端设备在至少一个服务小区上的DCI可以调度2个码字(即终端设备在至少一个服务小区中上被配置接收2个TB)，则终端设备可以在第一HARQ反馈码本中的第(T D*j+第一DAI-N)的比特位，至第(T D*j+第一DAI-1)的比特位，分别填充第一DCI调度的N个PDSCH对应的HARQ-ACK信息。
其中，第一HARQ反馈码本中的每个比特位填充的HAQR-ACK信息是每个服务小区传输的两个TB的HARQ-ACK信息逻辑与处理后的取值。
示例性的，若第一DCI调度两个服务小区中传输的下行信息，且所有服务小区中传输的DCI最大调度2个码字，则终端设备可以在第(T D*j+第一DAI-2)的比特位上填充上述两个服务小区中，索引值较小的服务小区传输的2个TB的HARQ-ACK信息逻辑与后的取值。另外，终端设备可以在第(T D*j+第一DAI-1)的比特位上填充上述两个服务小区中，索引值较大的服务小区传输的2个TB的HARQ-ACK信息逻辑与后的取值。
在一些实施例中，第一条件可以包括除以下条件之外的任一条件：
终端设备未被配置第一参数，且N个下行信息所在的服务小区中的至少一个服务小区上被配置的第二参数的取值为2。
也就是说，在终端设备未被配置HARQ-ACK空间捆绑，且终端设备被配置在至少一个服务小区上的DCI最大调度2个码字以外的任何场景中，终端设备均可以在第一HARQ反馈码本中的第(T D*j+第一DAI-N)的比特位，至第(T D*j+第一DAI-1)的比特位，分别填充第一DCI调度的N个PDSCH对应的HARQ-ACK信息。
在一示例中，参考图5所示的一种数据传输示意图三，网络设备可以在服务小区1和服务小区2中向终端设备传输下行信息，且服务小区1和服务小区2均未被配置基于码块组(Code Block Group，CBG)的传输。其中，PDCCH监测机会集合包括PDCCH监测机会1和PDCCH监测机会2。网络设备可以在PDCCH监测机会1中，通过服务小区1传输DCI a，且DCI a为第二DCI格式，DCI a用于调度PDSCH 1。在PDCCH监测机会1中，通过服务小区2传输DCI b，且DCI b为第二DCI格式，DCI b用于调度PDSCH 2。在PDCCH监测机会2中，通过服务小区1传输DCI c，且DCI c为第二DCI格式，DCI b用于调度PDSCH 3。在PDCCH监测机会2中，通过服务小区2传输DCI d，且DCI d为第一DCI格式，DCI d可以调度服务小区1的PDSCH 4和服务小区2传输的PDSCH 5。
DCI a的DAI＝1，DCI b的DAI＝2，DCI c的DAI＝3，DCI d由于调度两个下行信息，则DCI d的DAI＝1。
这样，终端设备可以根据DCI d中DAI的取值，确定第一HARQ反馈码本包括5个比特。终端设备在该第一HARQ反馈码本的第0的比特位填充DCI a调度的PDSCH 1对应的HARQ-ACK信息，在第1的比特位填充DCI b调度的PDSCH 2对应的HARQ-ACK信息，在第2的比特位填充DCI c调度的PDSCH 3对应的HARQ-ACK信息，在第3的比特位填充DCI d调度的服务小区1传输的PDSCH 4对应的HARQ-ACK信息，在第4的比特位填充DCI d调度的服务小区2传输的PDSCH 5对应的HARQ-ACK信息。综上，最终的第一HARQ反馈码本为：{ACK/NACK PDSCH 1，ACK/NACK PDSCH 2，ACK/NACK PDSCH 3，ACK/NACK PDSCH 4，ACK/NACK PDSCH 5}。
在另一示例中，参考图6所示的一种数据传输示意图四，网络设备可以在服务小区1和服务小区2中向终端设备传输下行信息，且服务小区1和服务小区2均未被配置基于CBG的传输。
其中，PDCCH监测机会集合包括PDCCH监测机会1至PDCCH监测机会4。网络设备可以在 PDCCH监测机会1中，通过服务小区1传输DCI a，且DCI a为第二DCI格式，DCI a用于调度PDSCH 1。在PDCCH监测机会1中，通过服务小区2传输DCI b，且DCI b为第二DCI格式，DCI b用于调度PDSCH 2。在PDCCH监测机会2中，通过服务小区1传输DCI c，且DCI c为第二DCI格式，DCI b用于调度PDSCH 3。在PDCCH监测机会2中，通过服务小区2传输DCI d，且DCI d为第一DCI格式，DCI d可以调度服务小区1的PDSCH 4和服务小区2传输的PDSCH 5。在PDCCH监测机会3中，通过服务小区1传输DCI e，且DCI e为第一DCI格式，DCI e可以调度服务小区1的PDSCH 6和服务小区2传输的PDSCH 7。在PDCCH监测机会4中，通过服务小区2传输DCI f，且DCI f为第二DCI格式，DCI f可以调度PDSCH 8。
网络设备可以根据上述方法，确定DCI a的DAI＝1，DCI b的DAI＝2，DCI c的DAI＝3，DCI d的DAI＝1，DCI e的DAI＝3，DCI f的DAI＝4。
在图6所示的场景中，当终端设备漏检DCI e时，终端设备可以根据PDCCH监测时机4中传输的DCI f携带的DAI，可以确定第一HARQ反馈码本的长度为8个比特。第一HARQ反馈码本可以为：{ACK/NACK PDSCH 1，ACK/NACK PDSCH 2，ACK/NACK PDSCH 3，ACK/NACK PDSCH 4，ACK/NACK PDSCH 5，NACK，NACK，ACK/NACK PDSCH 8}
需要说明的是，终端设备可以根据接收到的DCI携带的DAI信息，确定漏检了两个下行信息。然而，这两个下行信息是一个DCI调度的，还是两个DCI分别调度的，对于终端设备来说是透明的。
方式二、
在终端设备满足第二条件的情况下，终端设备基于第一DAI，确定第一HARQ反馈码本，可以通过以下方式实现：
终端设备在第一HARQ反馈码本中的第2*T D*j+2*(第一DAI-N)的比特位，至第2*T D*j+2*(第一DAI-N)+2*N-1的比特位，分别填充第一DCI调度的N个下行信息对应的HARQ-ACK信息；
其中，N个下行信息对应的HARQ-ACK信息在第一HARQ反馈码本的排列顺序，与N个下行信息所在的服务小区的索引值相关；
第二条件包括：终端设备未被配置第一参数，且在N个PDSCH所在的服务小区中的至少一个服务小区上被配置的第二参数的取值为2。
也就是说，当终端设备没有被配置HARQ-ACK空间捆绑(即终端设备没有被配置harq-ACK-SpatialBundlingPUCCH)，且终端设备在至少一个服务小区上的DCI可以调度2个码字(即终端设备在至少一个服务小区中上被配置接收2个TB)，则终端设备可以根据第一DAI的值，在第一HARQ反馈码本中确定2*N个比特位，分别填充第一DCI调度的N个下行信息对应的HARQ-ACK信息，每个下行信息对应2个TB。
其中，终端设备可以按照N个下行信息所在服务小区的索引值的大小顺序，在第一HARQ反馈码本中填充N个下行信息分别对应的HARQ-ACK信息。并且，每个服务小区传输的多个TB所对应的HARQ-ACK信息在第一HARQ反馈码本中的位置相邻。
示例性的，若第一DCI调度两个服务小区中传输的下行信息，且某个服务小区中传输的DCI可以调度2个码字，则终端设备可以在2*T D*j+2*(第一DAI-2)的比特位上填充索引值较小的服务小区传输的第一个TB对应的HARQ-ACK比特信息，在第2*T D*j+2*(第一DAI-1)的比特上填充索引值较小的服务小区传输的第二个TB的HARQ-ACK信息。另外，在2*T D*j+2*(第一DAI)的比特上填充索引值较大的服务小区传输的第一个TB的HARQ-ACK信息，在2*T D*j+2*(第一DAI)+1的比特上填充索引值较大的服务小区传输的第二个TB的HARQ-ACK信息。
示例性的，在图5所示的场景中，当终端设备在任意一个服务小区被配置DCI可以调度2个码字时，终端设备可以确定第一HARQ反馈码本的长度为10比特，并且第一HARQ反馈码本为：{ACK/NACK PDSCH 1，TB1，ACK/NACK PDSCH 1，TB2，ACK/NACK PDSCH 2，TB1，ACK/NACK PDSCH 2，TB2，ACK/NACK PDSCH 3，TB1，ACK/NACK PDSCH 3，TB2，ACK/NACK PDSCH 4，TB1，ACK/NACK PDSCH 4，TB2，ACK/NACK PDSCH 5，TB1，ACK/NACK PDSCH 5，TB2}。
实际应用中，在DCI为循环计数值的场景中，若终端设备连续漏检多个DCI，会导致终端设备生成的第一HARQ反馈码本的比特数，和网络设备期待终端设备生成的第一HARQ反馈码本的比特数，理解不一致的问题。
示例性的，参考图7所示，网络设备可以在服务小区1和服务小区2中向终端设备传输下行信息，且服务小区1和服务小区2均未被配置基于CBG的传输，终端设备支持最大1个码字。DAI为循环计数值，DAI包含2比特，即DAI的最大值均为4。
其中，PDCCH监测机会集合包括PDCCH监测机会1至PDCCH监测机会4。网络设备可以在 PDCCH监测机会1中，通过服务小区1传输DCI a，且DCI a为第二DCI格式，用于调度PDSCH 1。网络设备在PDCCH监测机会1中，通过服务小区2传输DCI b，且DCI b为第二DCI格式，用于调度PDSCH 2。
网络设备在PDCCH监测机会2中，通过服务小区1传输DCI c，且DCI c为第二DCI格式，用于调度PDSCH 3。在PDCCH监测机会2中，通过服务小区2传输DCI d，且DCI d为第一DCI格式，DCI d可以调度服务小区1的PDSCH 4和服务小区2的PDSCH 5。网络设备还可以在PDCCH监测机会3中，通过服务小区1传输DCI e，且DCI e为第二DCI格式，用于调度PDSCH 6。在PDCCH监测机会3中，通过服务小区2传输DCI f，且DCI f为第一DCI格式，用于调度服务小区1的PDSCH 7和服务小区2的PDSCH 8。在PDCCH监测机会4中，通过服务小区2传输DCI g，且DCI g为第一DCI格式，用于调度服务小区1的PDSCH 9和第二服务小区的PDSCH 10。
网络设备可以根据上述方法，确定DCI a的DAI＝1，DCI b的DAI＝2，DCI c的DAI＝3，DCI d的DAI＝1，DCI e的DAI＝2，DCI f的DAI＝4，DCI g的DAI＝2。
在图7所示的场景中，若终端设备漏检了PDCCH监测机会3中传输的DCI e和DCI f时，终端设备会根据最后一个DCI g确定最终的HARQ反馈码本的长度为6比特。而网络设备期望终端设备生成的HARQ反馈信息为10比特。
针对上述问题，本申请实施例提供的HARQ反馈码本确定方法中，还可以包括以下步骤：
若第一DAI减去第二DAI的差值小于N，且第一DCI为第一DCI格式，则终端设备设置j的值为j+1；
其中，第二DAI通过第二DCI携带；第二DCI调度的下行信息所在的服务小区中包括索引值为第一索引值的服务小区，第一索引值小于第二索引值，且终端设备在索引值大于第一索引值且小于第二索引值的服务小区上未接收到下行信息；
第二索引值为N个下行信息所在的服务小区对应的索引值中的最小值。
这里，终端设备还可以在PDCCH监测机会集合中接收第二DCI。第二DCI中包括第二DAI。
在一些实施例中，第二DCI可以是第一DCI格式，也可以是第二DCI格式；即，第二DCI可以调度一个下行信息，也可以调度多个下行信息，本申请实施例对此不做限定。
在一些实施例中，终端设备可以在同一个PDCCH监测机会中接收第一DCI和第二DCI。终端设备在同一个PDCCH监测机会中，可以按照服务小区的索引值由大到小的顺序检测DCI。
若终端设备检测到第二DCI调度的下行信息中包括索引值为第一索引值的服务小区，第一索引值小于第二索引值，并且终端设备在索引值大于第一索引值且小于第二索引值之间的服务小区上未收到下行信息，则可以认为第二DCI是第一DCI之前接收。
若终端设备检测到第二DCI调度的下行信息所在的服务小区中包括索引值为第一索引值的服务小区，第一索引值小于第一DCI调度的多个下行信息所在的服务小区中服务小区的索引值的最小值，并且，终端设备在索引值在第一索引值和上述服务小区的索引值最小值之间的服务小区上未收到下行信息，则可以认为第二DCI是第一DCI之前接收。在该场景下，终端设备确定其可能会出现连续漏检的情况。
需要说明的是，当第二DCI为第一DCI格式时，第一索引值可以是第二DCI调度的多个下行信息所在的服务小区中任意一个服务小区的索引值。例如第一索引值可以是多个服务小区中的最大索引值，第一索引值也可以是多个服务服务小区中的最小索引值，本申请实施例对此不做限定。另外，当第二DCI为第二DCI格式时，第一索引值，即第二DCI调度的下行信息所在的服务小区的索引值。
也就是说，若终端设备检测到第二DCI调度的某个下行信息所在的服务小区的索引值，小于第一DCI关联的N个服务小区中的最小索引值，并且终端设备这两个服务小区的索引值之间的服务小区上未收到下行信息，则可以认为终端设备可能会出现连续漏检的情况。
这样，终端设备在向第一HARQ反馈码本中填充第一DCI调度的N个下行信息对应的HARQ-ACK信息之前，可以计算第一DCI减去第二DCI的差值。若该差值小于N，且第一DCI为第一DCI格式，则终端设备确定已经出现了连续漏检的情况，此时终端设备可以设置j＝j+1。并根据调整后的j值，填充第一DCI调度的多个下行信息对应的HARQ-ACK信息。
在一示例中，若终端设备在第二DCI之后接收到第一DCI，且第一DCI调度两个服务小区中传输的下行信息，则第一HARQ反馈码本的构建过程如下：
首先，初始化第一临时值为0；初始化j＝0，其中j表示DAI达到最大值的次数。
其次，按照服务小区的索引值增加然后PDCCH监测机会的索引值增加的顺序，遍历所有的PDCCH监测机会和服务小区。
具体地，在当前的PDCCH监测机会和当前服务小区，若终端设备接收到第一DCI调度的多个下行信息，则：
判断第一DAI和第一临时值的大小关系；
如果第一DAI的取值小于等于第一临时值，则将j+1，并更新第一临时值为第一DAI的取值；
如果第一DAI的取值减去第一临时值的差值为1，则将j+1，并更新第一临时值为第一DAI的取值；
否则，更新第一临时值，为第一DAI的取值。
在一种可能的实现方式中，在确定了j的取值后，终端设备可以在满足第一条件时，在第一HARQ反馈码本的第(T D*j+第一DAI-2)的比特位填充上述两个服务小区中，索引值较小的服务小区传输的下行信息对应的HARQ-ACK信息。并且，在第(T D*j+第一DAI-1)的比特位，填充上述两个服务小区中，索引值较小的服务小区传输的下行信息对应的HARQ-ACK信息。
在另一种可能的实现方式中，在确定了j的取值后，终端设备可以在满足第二条件时，在第一HARQ反馈码本中的第2*T D*j+2*(第一DAI-2)个比特位，至第2*T D*j+2*(第一DAI)+1的比特位，分别填充第一DCI调度的N个下行信息对应的HARQ-ACK信息。
在另一示例中，在图7所示的场景，第一HARQ反馈码本的构建过程如下：
终端设备首先将第一临时值初始化为0，且j＝0；
终端设备可以在PDCCH监测时机1和服务小区1接收DCI a，DCI a的DAI＝1。终端设备确定当前第一临时值小于1，则更新第一临时值为1。基于此，终端设备在第一HARQ反馈码本中的第0的比特位填充DCI a调度的下行信息对应的HARQ-ACK信息。
接着，终端设备在PDCCH监测时机1和服务小区2接收到DCI b，DCI b的DAI＝2。终端设备确定当前第一临时值小于2，则更新第一临时值为2。并且，终端设备在第一HARQ反馈码本中的第1的比特位填充DCI b调度的下行信息对应的HARQ-ACK信息。
接下来，终端设备可以在PDCCH监测时机2和服务小区1接收到DCI c，DCI c的DAI＝3。终端设备确定当前第一临时值小于3，则更新第一临时值为3。并且，终端设备在第一HARQ反馈码本中的第2的比特位填充DCI c调度的下行信息对应的HARQ-ACK信息。
进一步地，终端设备可以在PDCCH监测时机2和服务小区2接收到DCI d，DCI d的DAI＝1。当前第一临时值为3，大于DCI d中DAI的取值，则调整j的取值为1，同时终端设备更新第一临时值为1。
基于此，终端设备在第一HARQ反馈码本中的第(4*1+1-2)的比特位，即第3的比特位填充DCI d调度的服务小区1中下行信息对应的HARQ-ACK信息，并在第(4*1+1-1)的比特位，即第4的比特位填充DCI d调度的服务小区2中下行信息对应的HARQ-ACK信息。
接着，终端设备在PDCCH监测时机4和服务小区2接收到DCI g，DCI g的DAI＝2。当前第一临时值为1，小于DCI g中DAI的取值。但是，终端设备检测到DCI g的DAI与前一个DCI d的DAI之间的差值为1，且当前DCI g为第一DCI格式，则终端设备调整j的取值为2，并更新第一临时值为2。这样，终端设备可以在第一HARQ反馈码本中的第(4*2+2-2)的比特位，即第8的比特位填充DCI g调度的服务小区1中下行信息对应的HARQ-ACK信息，并在第(4*2+2-1)的比特位，即第9的比特位填充DCI g调度的服务小区2中下行信息对应的HARQ-ACK信息。
由此可见，本申请实施例提供的HARQ反馈码本的确定方法，可以避免由于连续DCI漏检而导致终端设备生成的HARQ反馈码本包含的比特数，与网络设备期待终端设备生成的HARQ反馈码本包含的比特数，理解不一致的问题。
