当UE组织在某个反馈时刻需要上报的HARQ-ACK比特序列时，UE基于预定义的规则，以及需要在此反馈时刻上报HARQ-ACK的单个/多个载波上物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输的调度情况，确定各PDSCH传输与组织的HARQ-ACK比特序列中某个/某些比特的对应关系，这种操作称之为构造HARQ-ACK码本(Codebook)。HARQ-ACK Codebook包括：半静态码本和动态码本。
HARQ-ACK Codebook一般在PUCCH上传输，但当PUCCH传输与某个PUSCH传输在时域交叠时，PUCCH上承载的部分或全部UCI将复用到PUSCH上传输。在调度PUSCH的DCI format 0_1中可以指示复用传输的HARQ-ACK Codebook对应的DAI，可以称之为UL DAI。
目前，可以配置终端通过一个动态码本进行最多两个PDSCH组的HARQ-ACK反馈，而当上行DCI format 0_1中只存在单个或单组UL DAI时，此UL DAI如何用于生成该动态码本，目前还没有相应的解决方案。

为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、新空口(New Radio，NR)的混合自动重传请求应答(Hybrid Automatic Repeat reQuest Acknowledgement，HARQ-ACK)动态码本。
当UE组织在某个反馈时刻需要上报的HARQ-ACK比特序列时，UE基 于预定义的规则，以及需要在此反馈时刻上报HARQ-ACK的单个/多个载波上物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输的调度情况，确定各PDSCH传输与组织的HARQ-ACK比特序列中某个/某些比特的对应关系，这种操作称之为构造HARQ-ACK码本(Codebook)。
当通过下行控制信息(Downlink Control Information，DCI)指示半持续调度(Semi-Persistent Scheduling，SPS)PDSCH释放时，也需要UE使用HARQ-ACK比特确认其接收，以保证两侧对于SPS PDSCH是否处于激活状态的理解保持一致。
HARQ-ACK Codebook包括：半静态码本(Type-1)和动态码本(Type-2)。其中，前者针对所有可能的DCI指示和PDSCH传输都进行反馈，主要用于保证传输可靠性，反馈开销较大；后者只针对实际的DCI指示和PDSCH传输进行反馈，反馈开销较小，在DCI漏检情况较为常见时传输可靠性会受到一定的影响。
动态码本通过对实际调度的PDSCH传输或SPS PDSCH释放指示进行下行分配索引(Downlink Assignment Index，DAI)计数的方式，为每个实际使用的DAI值都预留了HARQ-ACK反馈比特。
如果UE通过检测到的其它DAI推测出有些DAI对应的PDSCH分配指示或SPS PDSCH释放指示并未收到，则将对应的反馈比特设置为NACK；否则，按照各PDSCH分配指示对应的PDSCH传输的解码结果，设置其对应的HARQ-ACK反馈比特，对于检测到的SPS PDSCH释放指示，将其对应的反馈比特设置为ACK。
DAI采用有限的比特数(单个DAI一般占用2比特)来指示，为了扩展其指示范围，引入了取模操作，即先从1开始顺序计数，然后再取模得到某个计数值对应的DAI值。下行调度中DAI的处理可参考下表。
DCI格式1_0中计数器DAI的值，以及DAI DCI格式1_1中计数器DAI或总数DAI的值

Figure PCTCN2020125771-appb-000002
在上表中，最高有效位(Most Significant Bit，MSB)；最低有效位(Least Significant Bit，LSB)；计数器DAI(Counter DAI，C-DAI)；总数DAI(Total DAI，T-DAI)。
Y为存在与PDCCH对应的PDSCH传输，或者存在指示SPS PDSCH释放的PDCCH的{服务小区、PDCCH监测机会}对的数量(Number of{serving cell，PDCCH monitoring occasion}-pair(s)in which PDSCH transmission(s)associated with PDCCH or PDCCH indicating SPS PDSCH release is present，denoted asY)，Y≥1。
当UE只配置了单个服务小区时，前述DAI只针对单个载波，按DCI指示的时间先后顺序逐一计数，可以称之为C-DAI。
当UE配置了多个服务小区时，为了进一步增加可靠性，新引入了T-DAI，用于指示截至当前时域检测位置接收到的所有DCI指示的数目，包括当前时域检测位置在各个服务小区上收到的所有DCI指示，因此仅当时域检测位置变化时，才会更新T-DAI的取值。
T-DAI与C-DAI结合使用，可以有效避免某个时域检测位置某个或某些服务小区上DCI指示丢失(只要不是所有服务小区上的DCI指示都丢失)时，UE和gNB对于DCI指示的传输理解不一致的情况。
在本申请实施例中，以下对每个DAI对应的HARQ-ACK比特序列的确定方式进行说明：
第一情况、当网络侧设备为UE的某个服务小区配置了参数PDSCH-Code BlockGroupTransmission，以开启基于码块组(Code Block Group，CBG)的HARQ传输时：
方式一、由DCI格式(format)1_1调度的PDSCH传输支持基于CBG的HARQ传输，单个DAI对应

个HARQ-ACK反馈比特。
其中，
Figure PCTCN2020125771-appb-000004
为针对

个配置了参数PDSCH-CodeBlockGroupTransmission的服务小区的

值的最大值；

为 服务小区c的参数maxNrofCodeWordsScheduledByDCI的取值，指示单个DCI可同时调度的传输块最大数目；
Figure PCTCN2020125771-appb-000008
为服务小区c的参数maxCodeBlockGroupsPerTransportBlock的取值，指示单个传输块可拆分的CBG最大数目。
如果针对某个服务小区c，
Figure PCTCN2020125771-appb-000009
则UE将
Figure PCTCN2020125771-appb-000010
比特中的最后
Figure PCTCN2020125771-appb-000011
个比特设置为NACK。
前
Figure PCTCN2020125771-appb-000012
个比特基于实际接收的传输块对应的各个CBG的解码情况进行设置。
方式二、由DCI format 1_0调度的PDSCH传输只支持基于传输块(Transport Block，TB)的HARQ传输，其与SPS PDSCH释放指示，SPS PDSCH接收一样，针对单个传输块都仅反馈单个HARQ-ACK比特；这些情况都属于单个DCI指示或PDSCH传输只对应单个传输块的情况。
第二情况、当网络没有为UE的某个服务小区配置参数PDSCH-CodeBlockGroupTransmission，即未开启基于CBG的HARQ传输时：
方式一、如果harq-ACK-SpatialBundlingPUCCH或harq-ACK-Spatial BundlingPUSCH参数没有为UE配置(即没有开启针对HARQ-ACK的Spatial Bundling，Spatial Bundling可以理解为同一个PDSCH传输对应的两个码字之间的HARQ-ACK反馈压缩合并；其中harq-ACK-SpatialBundlingPUCCH参数应用于在PUCCH上承载的HARQ-ACK传输，harq-ACK-SpatialBundlingPUSCH参数应用于在PUSCH上承载的HARQ-ACK传输)，并且为UE的至少某个服务小区的至少某个下行(DownLink，DL)带宽部分(Bandwidth Part，BWP)通过maxNrofCodeWordsScheduledByDCI参数配置了单次PDSCH接收最多对应两个传输块，则单个DAI对应2个HARQ-ACK比特，其中第一比特指示第一个传输块的HARQ-ACK，第二比特指示第二个传输块的HARQ-ACK。
方式二、如果harq-ACK-SpatialBundlingPUCCH或harq-ACK-SpatialBundlingPUSCH参数已为UE配置，并且为UE的至少某个服务小区的至少某个DL BWP通过maxNrofCodeWordsScheduledByDCI参数配置了单次PDSCH接收最多对应两个传输块，则单个DAI对应单个HARQ-ACK比 特，取值设置为第一个传输块的HARQ-ACK与第二个传输块的HARQ-ACK的逻辑与。
方式三、否则，单个DAI对应单个HARQ-ACK比特，取值设置为唯一传输块的HARQ-ACK。其中，否则即表示除方式一和方式二中所列情况之外的其它剩余情况，即既没有配置最多对应两个传输块，也没有配置Spatial Bundling相关参数，此时单个下行DCI只会调度单个传输块，因此单个DAI对应单个HARQ-ACK比特。
当网络侧设备为UE的某个或某些服务小区配置了参数PDSCH-Code BlockGroupTransmission以开启基于CBG的HARQ传输时，HARQ-ACK Codebook包含两个HARQ-ACK子码本(sub-codebook)。其中，第一个sub-codebook包含所有TB粒度的HARQ-ACK比特，涉及SPS PDSCH释放指示、SPS PDSCH接收，开启了基于CBG的HARQ传输的服务小区上由DCI format 1_0调度的PDSCH传输(这些PDSCH传输仅支持TB粒度的HARQ-ACK反馈)，以及没有开启基于CBG的HARQ传输的服务小区上由DCI format 1_0/1_1调度的PDSCH传输(这些PDSCH传输必然只支持TB粒度的HARQ-ACK反馈)对应的HARQ-ACK；第二个sub-codebook包含所有CBG粒度的HARQ-ACK比特，涉及开启了基于CBG的HARQ传输的服务小区上由DCI format 1_1调度的PDSCH传输对应的HARQ-ACK。HARQ-ACK Codebook由第一个sub-codebook和第二个sub-codebook顺序级联而成。
HARQ-ACK Codebook一般在PUCCH上传输，PUCCH的时域和频域信息在DCI中指示(有一个例外：SPS PDSCH的HARQ-ACK反馈PUCCH的频域信息可以由高层配置)。当PUCCH传输与某个PUSCH传输在时域交叠时，PUCCH上承载的部分或全部UCI将复用到PUSCH上传输。
对于HARQ-ACK动态码本，因为DCI漏检会影响HARQ-ACK Codebook的构建(包括Codebook中包含的HARQ-ACK比特数)，而HARQ-ACK比特数会影响其在PUSCH上复用传输时占用的时频资源，从而影响PUSCH上其它数据传输(例如，UL-SCH)的时频解映射和解码。为了避免上述HARQ-ACK比特数在UE和网络侧理解不一致导致的影响，在调度PUSCH的DCI format 0_1中可以指示复用传输的HARQ-ACK Codebook对应的DAI，可以 称之为UL DAI。UL DAI主要用于UE确定HARQ-ACK Codebook的HARQ-ACK比特数，并可以用来确定HARQ-ACK Codebook尾部HARQ-ACK比特对应的DCI的漏检情况。当HARQ-ACK Codebook只涉及TB粒度的HARQ-ACK反馈(即不涉及两个sub-codebook)时，DCI format 0_1中只指示单个UL DAI(由DCI域“1st downlink assignment index”指示)，对应于单一的HARQ-ACK Codebook，当HARQ-ACK Codebook同时涉及TB粒度的HARQ-ACK反馈和CBG粒度的HARQ-ACK反馈(即由两个sub-codebook顺序级联而成)时，DCI format 0_1中同时指示两个UL DAI，其中第一个UL DAI(由DCI域“1st downlink assignment index”指示)应用于第一个sub-codebook，第二个UL DAI(由DCI域“2nd downlink assignment index”指示)应用于第二个sub-codebook。
二、NR-U的HARQ-ACK动态码本增强。
对于动态码本引入的增强主要包括以下几点：
对动态调度的PDSCH进行显式分组，在调度DCI中指示调度的PDSCH对应的分组；同一个PDSCH分组对应的HARQ-ACK反馈都在同一个PUCCH上承载；
在单个PDSCH分组内进行C-DAI或T-DAI计数；
每个PDSCH分组维护一个新反馈指示(New Feedback Indicator，NFI)，通过翻转的方式指示是只传输新反馈，还是也需要重传之前的反馈；如果NFI翻转，则指示NFI翻转的DCI之前针对此PDSCH分组的所有反馈将被丢弃，仅传输此DCI及之后针对此PDSCH分组调度的PDSCH的HARQ-ACK反馈，如果NFI未翻转，则自从上一次NFI翻转之后针对此PDSCH分组的所有HARQ-ACK反馈都需要传输，即NFI取值相同的HARQ-ACK反馈都有效；由此，针对同一PDSCH分组的两次反馈请求，实际需要传输的HARQ-ACK比特数可能发生变化；
单个DCI可以请求一到多个PDSCH分组的HARQ-ACK反馈在同一个PUCCH上传输，典型地，单个下行调度DCI默认请求自身调度的PDSCH对应的PDSCH分组的HARQ-ACK反馈，此DCI还可以额外触发其它PDSCH分组的HARQ-ACK反馈在其指示的PUCCH上一并传输；
目前支持的PDSCH分组最大数目为2；
UE可以通过能力信息指示是否支持增强的动态码本。
当为UE配置了增强动态码本时，在上行non-fallback DCI，即DCI format 0_1中，是否存在针对额外的单个PDSCH分组的UL DAI可以由无线资源控制(Radio Resource Control，RRC)信令配置。然而，当DCI format 0_1中只存在单个PDSCH分组的UL DAI时，此UL DAI应用于哪个PDSCH分组，目前还没有相应的解决方案。
以下对本申请实施例的HARQ-ACK码本生成方法进行说明。
参见图2，图2是本申请实施例提供的HARQ-ACK码本生成方法的流程图。本申请实施例的HARQ-ACK码本生成方法可以应用于终端。
如图2所示，HARQ-ACK码本生成方法可以包括以下步骤：
步骤201、接收用于调度第一物理上行共享信道PUSCH的第一下行控制信息DCI，所述第一DCI包括第一DAI。
步骤202、根据所述第一DAI，确定N个物理下行共享信道PDSCH组中每个PDSCH组对应的第二DAI，N为正整数。
每个PDSCH组对应的第二DAI用于确定该PDSCH组的HARQ-ACK比特序列。
步骤203、根据确定的N个第二DAI，生成在所述第一PUSCH上传输的动态码本；其中，所述动态码本包含所述N个PDSCH组的HARQ-ACK比特序列。
具体实现时，所述根据确定的N个第二DAI，生成在所述第一PUSCH上传输的动态码本，具体可以包括：
根据确定的N个第二DAI，确定所述N个PDSCH组中每个PDSCH组的HARQ-ACK序列；
根据所述N个PDSCH组中每个PDSCH组的HARQ-ACK序列，生成所述动态码本。
具体实现时，可选地，可以按照所述N个PDSCH组的组号的大小排列顺序，依次级联所述N个PDSCH组中每个PDSCH组的HARQ-ACK序列，生成所述动态码本，但不仅限于此。
本实施例的HARQ-ACK码本生成方法，终端在接收用于调度第一物理上行共享信道PUSCH的第一下行控制信息DCI，所述第一DCI包括第一DAI之后，可以根据所述第一DAI，确定N个物理下行共享信道PDSCH组中每个PDSCH组对应的第二DAI，进而根据确定的N个第二DAI，生成在所述第一PUSCH上传输的动态码本；其中，所述动态码本包含所述N个PDSCH组的HARQ-ACK比特序列，N为正整数。可见，本申请实施例提供了一种基于第一DAI生成包含所述N个PDSCH组的HARQ-ACK比特序列的动态码本的解决方案，进而可以保证动态码本的传输的可靠性。
在本实施例中，可选地，所述根据所述第一DAI，确定N个物理下行共享信道PDSCH组中每个PDSCH组对应的第二DAI，包括：
确定所述第一DAI与N个PDSCH组的第一关系；
根据所述第一关系，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI。
具体实现时，对于所述第一DAI与N个PDSCH组的第一关系的确定，可以包括以下两种实施方式。
实施方式一、所述第一关系满足：所述第一DAI与所述N个PDSCH组中的至少一个PDSCH组对应。
也就是说，在实施方式一中，所述第一DAI必定与所述N个PDSCH组中的至少一个PDSCH组具有对应关系。
在N等于1，即所述N个PDSCH组仅包括一个PDSCH组的情况下，第一DAI与该PDSCH组对应。
在N大于1的情况下，可选地，所述第一关系满足以下任意一项：
所述第一DAI与所述N个PDSCH组对应；
所述第一DAI与所述N个PDSCH组中的第一PDSCH组对应。
需要说明的是，第一PDSCH组为所述N个PDSCH组中的一个PDSCH组。
具体实现时，所述第一PDSCH组可以为所述N个PDSCH组中的任一PDSCH组。进一步地，所述第一PDSCH组可以满足以下任意一项：
所述第一PDSCH组为目标DCI调度的PDSCH所在的PDSCH组，所述 目标DCI为所述终端最后检测到的用于调度所述N个PDSCH组中PDSCH的DCI；
所述第一PDSCH组由协议约定；
所述第一PDSCH组由网络侧设备配置。
为方便理解，以下对各情况分别进行说明：
情况一、所述第一PDSCH组满足：所述第一PDSCH组为目标DCI调度的PDSCH所在的PDSCH组，所述目标DCI为所述终端最后检测到的用于调度所述N个PDSCH组中PDSCH的DCI。
在情况一中，所述第一PDSCH组由终端自主基于每个PDSCH组的调度时间确定。具体说明如下。
每个PDSCH组包括至少一个PDSCH，每个PDSCH对应一个用于调度其传输的DCI，每个DCI调度PDSCH的PDSCH调度时间可能不同。
示例性地，假设所述N个PDSCH组包括PDSCH组1、PDSCH组2和PDSCH组3，终端最后检测到用于调度所述N个PDSCH组中PDSCH的DCI为调度PDSCH组3中PDSCH的DCI。因此，可以将的PDSCH组3确定为所述第一PDSCH组。
情况二、所述第一PDSCH组满足所述第一PDSCH组由协议约定的情况。
在情况二中，所述第一PDSCH组为协议约定的所述N个PDSCH组中的一个PDSCH组。
例如，可以由协议约定第一PDSCH组为N个PDSCH组中的第一个PDSCH组或最后一个PDSCH组，或者为组号最小或最大的PDSCH组，或者为在生成动态码本时对应的HARQ-ACK比特序列放在动态码本对应的比特序列的最开始或最尾部的PDSCH组，或者组号为指定取值的PDSCH组。
情况三、所述第一PDSCH组满足所述第一PDSCH组由网络侧设备配置。
在情况三中，所述第一PDSCH组为网络侧设备配置的所述N个PDSCH组中的一个PDSCH组。
例如，可以由网络侧设备配置第一PDSCH组为N个PDSCH组中的第 一个PDSCH组或最后一个PDSCH组，或者为组号最小或最大的PDSCH组，或者为在生成动态码本时对应的HARQ-ACK比特序列放在动态码本对应的比特序列的最开始或最尾部的PDSCH组，或者组号为指定取值的PDSCH组。
可见，相比于情况一，在情况二和情况三中，终端无需自主确定所述第一PDSCH组，从而可以降低终端负担。相比于情况二，在情况一和情况三中，所述第一PDSCH组的确定的灵活度更高。相比于情况三，在情况一和情况二中，终端无需与网络侧设备交互以确定所述第一PDSCH组，从而可以降低信令开销。
实施方式二、所述确定所述第一DAI与N个PDSCH组的第一关系，包括：
根据预设规则，确定所述第一DAI与N个PDSCH组的第一关系；
其中，所述预设规则包括以下至少一项：
根据目标DCI调度的所在的PDSCH组确定所述第一DAI对应的PDSCH组，所述目标DCI为所述终端最后检测到的用于调度所述N个PDSCH组中PDSCH的DCI；
根据协议约定确定所述第一DAI对应的PDSCH组；
根据网络侧设备的配置信息确定所述第一DAI对应的PDSCH组。
对于实施方式二，可选地，所述第一关系满足以下任意一项：
所述第一DAI与所述N个PDSCH组中的第五PDSCH组对应，所述第五PDSCH组为所述N个PDSCH组中的任一个PDSCH组；
所述第一DAI不与所述N个PDSCH组中的任意一个PDSCH组对应。
需要说明的是，所述第五PDSCH组与前述第一PDSCH组类似，具体可参照前述关于第一PDSCH组的描述，此处不再赘述。
可见，对于实施方式二，在所述第一DAI与N个PDSCH组的第一关系基于预设规则确定的情况下，所述第一DAI可以不与所述N个PDSCH组中的任意一个PDSCH组对应，也就是说，所述第一DAI与所述N个PDSCH组无关。因此，在实施方式二中，所述第一DAI不一定与所述N个PDSCH组具有对应关系。
由前述内容可知，在本实施例中，所述第一DAI与N个PDSCH组的第 一关系包括以下表现方式。
第一表现方式、所述第一DAI与所述N个PDSCH组中的第一PDSCH组对应；或，所述第一DAI与所述N个PDSCH组中的第五PDSCH组对应。
第二表现方式、所述第一DAI与所述N个PDSCH组对应。
第三表现方式、所述第一DAI不与所述N个PDSCH组中的任意一个PDSCH组对应。
在本实施例中，所述根据所述第一关系，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI的具体实施方式，与所述第一DAI与N个PDSCH组的第一关系的具体表现方式相关。因此，以下针对上述三种表现方式，对所述第一关系，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI的具体实施方式进行说明。
对于上述第一表现方式
在所述第一DAI与所述第一PDSCH组对应的情况下，可选地，所述根据所述第一关系，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI，包括：
将所述第一DAI确定为所述第一PDSCH组对应的第二DAI；
将第三DAI确定为第二PDSCH组对应的第二DAI；
其中，所述第三DAI为所述终端最后检测到的与第二PDSCH组对应的DCI中的DAI；所述第二PDSCH组为所述N个PDSCH组中除所述第一PDSCH组之外的任一PDSCH组。
为方便理解，示例说明如下：
假设所述N个PDSCH组包括PDSCH组0和PDSCH组1，PDSCH组0为所述第一PDSCH组，PDSCH组1为所述第二PDSCH组。
则对于PDSCH组0，其对应的第二DAI即为所述第一DAI；对于PDSCH组1，其对应的第二DAI即为：所述终端最后检测到的与PDSCH组对应的DCI中的DAI。这里与PDSCH组对应的DCI，是指此DCI调度的PDSCH归属于此PDSCH组。
在所述第一DAI与所述N个PDSCH组中的第五PDSCH组对应的情况下，可选地，所述根据所述第一关系，确定所述N个PDSCH组中每个PDSCH 组对应的第二DAI，包括：
将所述第一DAI确定为所述第五PDSCH组对应的第二DAI；
将第八DAI确定为第六PDSCH组对应的第二DAI；
其中，所述第八DAI为所述终端最后检测到的与第六PDSCH组对应的DCI中的DAI；所述第六PDSCH组为所述N个PDSCH组中除所述第五PDSCH组之外的任一PDSCH组。
该情况中，所述根据所述第一关系，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI的实施原理，与上述所述第一DAI与所述第一PDSCH组对应的情况中，所述根据所述第一关系，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI的实施原理相同，具体可参考前述描述，此处不再赘述。
对于上述第二表现方式
可选地，所述根据所述第一关系，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI，包括：
获取所述N个PDSCH组中每个PDSCH组对应的第二DCI中的第四DAI，每个PDSCH组对应的第二DCI为所述终端最后检测到的与该PDSCH组对应的DCI；
将第一值与所述第一DAI的取值进行比较，得到相应的比较结果；其中，所述第一值基于获取到的N个第四DAI的取值的和确定；
根据所述比较结果，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI。
具体实现时，第一实现方式中，所述第一值可以为获取到的N个第四DAI的取值的和。
第二实现方式中，所述第一值可以为通过对获取到的N个第四DAI的取值的和进行取模运算后得到的值。假设所述N个PDSCH中各个PDSCH分组对应的第四DAI分别为DAI1，DAI2，…DAIN，则所述第一值DAI_Sum可以通过以下公式计算：

其中，Round_Size为取模运算的模数，其与单个DAI占用的比特数L相 关。可选地，Round_Size＝2L。如：当DAI使用2比特指示时，Round_Size＝4。
在第二表现方式中，所述第一DAI与所述N个PDSCH组对应，因此，所述第一DAI与获取到的N个第四DAI的取值的和对应，终端可以将所述第一DAI与所述第一值进行比较，得到比较结果。之后，根据比较结果，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI。
所述比较结果可以用于确定终端是否存在用于调度所述N个PDSCH组的PDSCH的DCI的漏检。
具体地，若所述比较结果为所述第一值与所述第一DAI的取值相等，则终端可以确定终端不存在用于调度所述N个PDSCH组的PDSCH的DCI的漏检。对于不存在漏检的情况，终端可以将所述N个PDSCH组中每个PDSCH组对应的最后检测到的DCI中的DAI确定为该PDSCH组对应的第二DAI。
若所述比较结果为所述第一值与所述第一DAI的取值不相等，终端可以确定终端存在用于调度所述N个PDSCH组的PDSCH的DCI的漏检。对于存在漏检的情况，终端可以通过以下方式，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI。
可选地，所述根据比较结果，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI，包括：
确定第五DAI，所述第五DAI用于指示漏检的用于调度所述N个PDSCH组的PDSCH的DCI的个数；

具体实现时，所述第五DAI可以根据所述第一值与所述第一DAI的取值确定。记所述第一值为DAI_Sum，所述第一DAI的取值为UL_DAI，所述第五DAI为DAI_Diff，可选地，DAI_Diff可以通过以下公式计算得到：
DAI_Diff＝(UL_DAI–DAI_Sum-1)mod Round_Size+1
其中，X mod Y表示将X对Y进行取模，Round_Size为取模运算的模数，其与单个DAI占用的比特数L相关。可选地，Round_Size＝2L。如：当DAI使用2比特指示时，Round_Size＝4。例如，当UL_DAI＝3，DAI_Sum ＝4时，DAI_Diff＝(3–4–1)mod 4+1＝3。
在本实施例中，所述根据所述第五DAI，确定所述N个PDSCH组中每个PDSCH组对应的第二DAI的具体实现方式，与所述终端是否开启基于CBG的HARQ传输相关。在本实施例中，若所述终端的某些服务小区配置了参数PDSCH-CodeBlockGroupTransmission，即可视为所述终端开启了基于CBG的HARQ传输。

在场景二中，终端开启基于CBG的HARQ传输，因此，用于调度所述N个PDSCH组的PDSCH的DCI可以包括第一类型DCI和第二类型DCI。其中，对于所述第一类型DCI调度的PDSCH，其基于TB粒度反馈HARQ-ACK；对于所述第二类型DCI调度的PDSCH，其基于TB粒度反馈HARQ-ACK。

可选地，所述根据所述第五DAI和确定的N个第二DAI，生成在所述第一PUSCH上传输的动态码本，包括：
根据所述第五DAI，生成目标比特序列。
具体实现时，终端在根据所述第五DAI生成目标比特序列后，可以将所述目标比特序列添加至所述动态码本中。也就是说，在该情况下，所述动态码本包括所述N个PDSCH组的HARQ-ACK比特序列，以及所述目标比特序列。
这样，可以使得在终端和网络侧设备理解的动态码本的大小，进而可以使得网络侧设备成功获取所述动态码本，提高数据传输的可靠性。

参见图3，图3是本申请实施例提供的HARQ-ACK码本生成方法的流程图。本申请实施例的信息发送方法应用于网络侧设备。
如图3所示，信息发送方法可以包括以下步骤：
步骤301、发送用于调度第一物理上行共享信道PUSCH的第一下行控制信息DCI，所述第一DCI包括第一DAI，所述第一DAI用于在所述第一PUSCH上传输的动态码本的生成；其中，所述动态码本包含所述N个物理下行共享信道PDSCH组的HARQ-ACK比特序列，N为正整数。
可选地，所述第一DAI与N个PDSCH组中的至少一个PDSCH组对应。
可选地，在N大于1的情况下，所述第一DAI与所述N个PDSCH组对应；或，所述第一DAI与所述N个PDSCH组中的第一PDSCH组对应。

具体实现时，一种实现方式中，所述第一DAI的取值可以为N个第九DAI的取值的和；另一种实现方式中，所述第一DAI的取值可以通过对N个第九DAI的取值的和进行取模运算得到。
可选地，所述第一DAI不与所述N个PDSCH组中的任意一个PDSCH组对应。
在该情况下，第一DAI可以设置为任意值，或者设置为默认值，如4。
本实施例的信息发送方法，网络侧设备发送用于调度第一物理上行共享信道PUSCH的第一下行控制信息DCI，所述第一DCI包括第一DAI，所述第一DAI用于在所述第一PUSCH上传输的动态码本的生成；其中，所述动态码本包含所述N个物理下行共享信道PDSCH组的HARQ-ACK比特序列，N为正整数。这样，终端在接收到第一DAI后，可以基于第一DAI生成动态码本，从而可以提高动态码本传输的可靠性。
需要说明的是，本实施例作为与上述方法实施例对应的网络侧设备的实施方式，因此，可以参见上述方法实施例中的相关说明，且可以达到相同的有益效果。为了避免重复说明，在此不再赘述。
另外，本申请实施例中介绍的多种可选的实施方式，彼此可以相互结合实现，也可以单独实现，对此本申请实施例不作限定。
为方便理解，示例说明如下：
在本申请实施例中，当为UE配置了下行增强动态码本，并且上行DCI format 0_1中只存在单个或单组UL DAI时，UL DAI的含义及应用可以采用如下某种方案：
方案一：基于与由DCI format 0_1调度的PUSCH在时域交叠并需要在其上承载的增强动态码本对应的触发PDSCH分组数目来确定此DCI format 0_1中的UL DAI值(即DCI format 0_1中“1st downlink assignment index”域和/或“2nd downlink assignment index”域的取值)的含义，可以采用如下操作：
当增强动态码本只对应单个触发PDSCH分组时，UL DAI值对应于此触发的单个PDSCH分组，对应的HARQ-ACK比特的确定可以采用操作2，参 见下文中的描述。
当增强动态码本对应多于一个触发PDSCH分组时，采用如下某种方式：
UL DAI值对应于所有触发的PDSCH分组的DAI之和(并考虑取模运算)，或者在PUSCH上承载的增强动态码本对应的动态调度PDSCH接收/SPS PDSCH释放指示数目(并考虑取模运算)。
其中，各个PDSCH分组应用的DAI值或对应的HARQ-ACK比特的确定可以采用操作1。
UL DAI值对应于在增强动态码本传输之前最近调度的PDSCH分组，对应的HARQ-ACK比特的确定可以采用操作2，参见下文中的描述。
UL DAI值对应于协议规定，或高层参数配置的某个PDSCH分组，例如第一组或第二组，对应的HARQ-ACK比特的确定可以采用操作2。
方案二：DCI format 0_1中的UL DAI固定应用于单个PDSCH分组，无论其调度的PUSCH上承载的PDSCH分组数目是否大于1，可以采用如下某种方式：
UL DAI值对应于协议规定，或高层参数配置的某个PDSCH分组，例如第一组或第二组，对应的HARQ-ACK比特的确定可以采用操作2。
UL DAI值对应于在增强动态码本传输之前最近调度的PDSCH分组，对应的HARQ-ACK比特的确定可以采用操作2。
上述方案一和方案二在一些情况下的实际操作完全一致，仅前提假设不同，一个是区分增强动态码本对应的PDSCH分组数目分别处理，一个是不作PDSCH分组数目的区分。
以下对上述操作1和操作2进行说明。
操作1：当DCI format 0_1中的UL DAI指示多于一个触发PDSCH分组的DAI之和，或者指示增强动态码本对应的动态调度PDSCH接收/SPS PDSCH释放指示数目时，可以采用如下方式确定各个PDSCH分组应用的DAI值或对应的HARQ-ACK比特：
第一步：取各个触发PDSCH分组最近的下行调度I为DCI format 1_0，则为此DCI format 1_0中的C-DAI；如果最近的下行调度DCI为DCI format 1_1，则为此DCI format 1_1中的T-DAI)，并计算各个PDSCH分组的C- DAI/T-DAI之和(并考虑取模运算)与UL DAI之间的关系，如果相等，则认为不存在DCI漏检，此时执行第二步，否则，认为某个PDSCH分组存在DCI漏检，此时执行第三步。当增强动态码本对应于N个PDSCH分组时，假设各个PDSCH分组的DAI分别为DAI1，DAI2，…DAIN，则上述计算各个PDSCH分组的C-DAI/T-DAI之和(并考虑取模运算)DAI_Sum可以表示为：
Figure PCTCN2020125771-appb-000016
这里Round_Size为取模运算的模数，当DAI使用2比特指示时，Round_Size＝4。
第二步：基于各个触发PDSCH分组最近的下行调度DCI format 1_0/1_1中的C-DAI/T-DAI确定此PDSCH分组对应的HARQ-ACK比特序列数目及取值，可沿用在PUCCH上承载时构造HARQ-ACK Codebook的操作流程(不涉及UL DAI的使用)，但参数harq-ACK-SpatialBundlingPUCCH由harq-ACK-SpatialBundlingPUSCH替换。
第三步：计算DAI差异，假设各个PDSCH分组的C-DAI/T-DAI之和(并考虑取模运算)为DAI_Sum，DCI format 0_1中的UL DAI值为UL_DAI，则DAI差异DAI_Diff＝(UL_DAI–DAI_Sum-1)mod Round_Size+1。DAI_Diff可以理解为漏检的DCI数目，针对其应用的目标的不同可以采用如下某种方式：
方式1：DAI_Diff应用于协议规定，或高层参数配置的某个PDSCH分组，例如第一组或第二组。
方式2：DAI_Diff应用于HARQ-ACK比特序列放在增强动态码本中最尾部的PDSCH分组，这样至少HARQ-ACK比特序列放在增强动态码本中最开始处的PDSCH分组的除了尾部之外的其它HARQ-ACK比特不会受到DCI漏检的影响。
方式3：DAI_Diff应用于在增强动态码本传输之前最近调度的PDSCH分组。
方式4：DAI_Diff不应用于任何PDSCH分组，仅用于在UE和eNB两侧对齐HARQ-ACK Codebook的大小，避免对于UL-SCH的RE解映射和解码造成影响。
对于上述方式1、方式2和方式3，在确定DAI_Diff应用的PDSCH分组 之后，在基于NR Rel-15流程确定了此PDSCH分组的HARQ-ACK比特序列(此时各个PDSCH分组在确定HARQ-ACK比特序列时，只使用DCI中指示的DAI值，不使用UL DAI值)之后，再在确定的HARQ-ACK比特序列的尾部应用DAI_Diff，在应用DAI_Diff时可以采用如下操作：
如果harq-ACK-SpatialBundlingPUSCH参数没有为UE配置，并且为UE的至少某个服务小区的至少某个DL BWP通过maxNrofCodeWordsScheduledByCI参数配置了单次PDSCH接收最多对应两个传输块，则每个缺失的DAI对应2个HARQ-ACK比特，此时在上述确定的HARQ-ACK比特序列的尾部添加DAI_Diff×2个取值为’0’的比特，对应DAI_Diff×2个NACK。
否则，每个缺失的DAI对应单个HARQ-ACK比特，此时在上述确定的HARQ-ACK比特序列的尾部添加DAI_Diff个取值为’0’的比特，对应DAI_Diff个NACK。
上述DAI_Diff应用操作适用于当UE的任何服务小区都没有开启基于CBG的HARQ传输时。
当UE的某些服务小区配置了参数PDSCH-CodeBlockGroupTransmission，即开启了基于CBG的HARQ传输时，单个PDSCH分组的HARQ-ACK Codebook由两个HARQ-ACK sub-codebook级联而成，其中第一个sub-codebook针对TB进行HARQ-ACK反馈，第二个sub-codebook针对CBG进行HARQ-ACK反馈。此时对于TB级的sub-codebook，按照上述操作应用DAI_Diff，对于CBG级的sub-codebook，在应用DAI_Diff时可以采用如下操作：
在上述确定的HARQ-ACK比特序列的尾部添加
Figure PCTCN2020125771-appb-000017
个取值为’0’的比特，对应
Figure PCTCN2020125771-appb-000018
个NACK，其中
Figure PCTCN2020125771-appb-000019
为针对
Figure PCTCN2020125771-appb-000020
个配置了参数PDSCH-CodeBlockGroupTransmission的服务小区的
Figure PCTCN2020125771-appb-000021
值的最大值，
Figure PCTCN2020125771-appb-000022
为服务小区c的参数maxNrofCodeWordsScheduledByDCI的取值，指示单个DCI可同时调度的传输块最大数目，
Figure PCTCN2020125771-appb-000023
为服务小区c的参数maxCodeBlockGroupsPerTransportBlock的取值，指示单个传输块可拆分的 CBG最大数目。
对于上述方式4，先确定各个触发PDSCH分组的HARQ-ACK比特序列(此时各个PDSCH分组在确定HARQ-ACK比特序列时，只使用DCI中指示的DAI值，不使用UL DAI值)，然后基于各个触发PDSCH分组的HARQ-ACK比特序列确定完整的HARQ-ACK Codebook(例如，将各个触发PDSCH分组的HARQ-ACK比特序列按组号从小到大依次级联，得到完整的HARQ-ACK Codebook)，最后，采用如下操作之一，在HARQ-ACK Codebook尾部添加对齐比特：
当单个触发PDSCH分组只涉及TB级的反馈(即UE的所有服务小区都没有配置参数PDSCH-CodeBlockGroupTransmission以开启基于CBG的HARQ传输)时，在HARQ-ACK Codebook尾部添加DAI_DiffTB×Bit_Num_Per_DAITB个取值为’0’的比特，每个比特对应单个NACK，其中DAI_DiffTB为基于DCI format 0_1中的UL DAI计算出来的DAI_Diff，Bit_Num_Per_DAITB为每个DAI对应的HARQ-ACK比特数，此时Bit_Num_Per_DAITB为TB粒度。
当单个触发PDSCH分组涉及CBG级的反馈(即UE的至少一个服务小区配置了参数PDSCH-CodeBlockGroupTransmission以开启基于CBG的HARQ传输)时，首先在HARQ-ACK Codebook尾部添加DAI_DiffTB×Bit_Num_Per_DAITB个取值为’0’的比特，每个比特对应单个NACK，其中DAI_DiffTB为基于DCI format 0_1中的第一个UL DAI(由“1st downlink assignment index”域指示)计算出来的DAI_Diff，Bit_Num_Per_DAITB为每个DAI对应的HARQ-ACK比特数，为TB粒度；其次在HARQ-ACK Codebook尾部进一步添加DAI_DiffCBG×Bit_Num_Per_DAICBG个取值为’0’的比特，每个比特对应单个NACK，其中DAI_DiffCBG为基于DCI format 0_1中的第二个UL DAI(由“2nd downlink assignment index”域指示)计算出来的DAI_Diff，Bit_Num_Per_DAICBG为每个DAI对应的HARQ-ACK比特数，为CBG粒度。
上述Bit_Num_Per_DAITB可基于如下方式确定：
如果harq-ACK-SpatialBundlingPUSCH参数没有为UE配置，并且为UE 的至少某个服务小区的至少某个DL BWP通过max Nr of Code Words Scheduled ByDCI参数配置了单次PDSCH接收最多对应两个传输块，则Bit_Num_Per_DAITB取值为2，否则Bit_Num_Per_DAITB取值为1。
上述Bit_Num_Per_DAICBG可基于如下方式确定：
Bit_Num_Per_DAICBG取值为
Figure PCTCN2020125771-appb-000024
的含义参见前面的描述。
操作2：当UL DAI值对应单个PDSCH分组时，可沿用在PUCCH上承载时构造HARQ-ACK Codebook的操作流程，确定此PDSCH分组对应的HARQ-ACK比特序列。
当每个触发PDSCH分组的码本对应两个sub-codebook时，基于NR Rel-15在DCI format 0_1中包含两个UL DAI值，分别对应第一个sub-codebook和第二个sub-codebook。对于每个sub-codebook可以分别应用上述方案及涉及的方式。
如图4所示，N个PDSCH组包括PDSCH组0和PDSCH组1。PDSCH组0包括两个PDSCH，分别为D1和D2，且UE仅检测到D1，未检测到D2。PDSCH组1包括四个PDSCH，分别为D3、D4、D5和D6，且UE仅检测到D3、D4和D5，未检测到D6。
在图4中，UCI1传输失败；传输UCI2的PUCCH与PUSCH在时域交叠，UCI2复用在PUSCH上传输。位于D6之后的DCI用于调度PUSCH，该DCI可以指示UL DAI。
