请参见图1，图1是本发明实施例可应用的一种网络系统的结构图，如图1所示，包括终端11和网络设备12，其中，终端11可以是用户终端或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本发明实施例中并不限定终端11的具体类型。上述网络设备12可以是5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者发送接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备12可以是主节点(Master Node，MN)，或者辅节点(Secondary Node，SN)。需要说明的是，在本发明实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
为了方便理解，以下结合对本发明实施例涉及的一些内容进行说明：
一、NR的回退下行控制信息(Fallback Downlink Control Information，Fallback DCI)格式或非回退下行控制信息(non-Fallback DCI)格式
NR中上行和下行调度DCI都区分Fallback DCI格式和non-Fallback DCI格式，其中Fallback DCI格式的引入主要是通过精简调度指示信息以保证网络覆盖性能，Fallback DCI格式中的指示域较少，一些扩展或优化功能的启用或信息指示较为受限，一般认为其中不包含与可区分终端配置的扩展、优化或可选功能对应的指示域；non-Fallback DCI格式则偏重于保障调度指示信息较为详尽地指示，并且可根据需要开启一些扩展或优化的功能，因此在Fallback DCI格式中指示域的基础上，还增加了一些其它指示域，例如针对一些扩展、优化或可选功能的指示信息新增了对应的指示域，单个DCI包含的指示域列表及对应的比特数与某个终端的具体配置有关，比特开销较大。
二、NR或增强的高可靠低延迟通信(enhanced Ultra Reliable Low Latency Communication，eURLLC)的SPS PDSCH对应的HARQ-ACK反馈
通信系统中引入了SPS PDSCH(在激活下行SPS传输之后，周期性发起的PDSCH传输，这些PDSCH传输没有对应的DCI指示，基于预定义的方式进行传输)传输。对于下行SPS传输，网络设备保证在为终端配置的某个服务小区组中，最多只有单个服务小区配置了半静态调度配置(SPS-Config)配置项，对应的SPS PDSCH传输间隔最小为10毫秒，在SPS-Config配置项中包含参数n1PUCCH-AN，用于指示当UE仅传输针对SPS PDSCH对应的HARQ-ACK时使用的物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源，此PUCCH资源可承载1比特HARQ-ACK。对于在时隙n内结束的SPS PDSCH传输，终端在时隙n+k内反馈此SPS PDSCH传输对应的HARQ-ACK，其中k由激活此SPS PDSCH传输的DCI中的PDSCH-to-HARQ-timing-indicator指示域来确定。
为了尽可能缩短业务数据的传输时延，提出网络设备可以为单个UE配置多套同时生效的SPS-Config配置项(单个服务小区的某个带宽部分(Bandwidth Part，BWP)最多可以同时配置8套)，并且对应的SPS PDSCH传输间隔可以缩短到最小为单个时隙。此时当终端仅传输针对SPS PDSCH对应的HARQ-ACK时，HARQ-ACK比特数也相应地扩展为多个比特。为此在eURLLC中可以将参数n1PUCCH-AN扩展为参数SPS-PUCCH-AN-List，用于指示一个PUCCH资源列表，其中最多可以包含4个PUCCH资源，不同的PUCCH资源对应于不同的比特数范围，这些PUCCH资源对应的比特数范围相互邻接形成单个完整的比特数范围，邻接点对应的门限，即单个PUCCH资源对应的比特数范围的上界(其加一构成下一PUCCH资源对应的比特数范围的下界)，可以在高层配置中给出，或者为默认值1706。终端根据某次实际需要传输的仅针对SPS PDSCH对应的HARQ-ACK比特数选择上述PUCCH资源列表中的某个PUCCH资源(当不包含循环冗余校验码(Cyclic redundancy check，CRC)校验比特的SPS PDSCH对应的HARQ-ACK比特数落在此PUCCH资源的比特数范围内时)承载这些针对SPS PDSCH对应的HARQ-ACK。
三、NR的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，也需要终端使用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。如果终端通过检测到的其它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。

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。
当终端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，终端和网络设备对于DCI指示的传输理解不一致的情况。
四、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；
支持的PDSCH分组最大数目为2；
终端可以通过能力信息指示是否支持增强的动态码本。
NR-U针对HARQ-ACK动态码本以及动态码本增强并没有单独考虑SPS PDSCH，以下对本发明实施例的HARQ-ACK处理方法进行说明。
请参见图2，图2是本发明实施例提供的一种HARQ-ACK处理方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201，确定N1个SPS PDSCH归属的N2个第一PDSCH分组，N1和N2均为正整数，且N1大于或等于N2，所述N2个第一PDSCH分组用于确定N2个第一比特序列，所述N2个第一比特序列包括所述N1个SPS PDSCH对应的HARQ-ACK；
步骤202，生成包含所述N2个第一比特序列的目标动态码本，所述N2个第一比特序列位于所述目标动态码本的尾部，或者所述第一比特序列位于目标PDSCH分组对应的目标比特序列的尾部，所述目标PDSCH分组为所述第一比特序列对应的第一PDSCH分组。
本发明实施例中，上述N2个第一PDSCH分组为目标动态码本对应或涉及的PDSCH分组的部分或全部。上述目标动态码本可以理解为支持PDSCH分组相关增强的动态码本，即待反馈的HARQ-ACK比特序列。同一个第一PDSCH分组内的一个或者多个SPS PDSCH传输对应的HARQ-ACK可以组成一个第一比特序列。后面提及的SPS PDSCH都可以理解为SPS PDSCH传输。在N1个SPS PDSCH归属于多个PDSCH分组时，可以对应生成多个第一比特序列，每个PDSCH分组与单个第一比特序列对应。在构建动态码本(即上述目标动态码本)时，可以将多个第一比特序列置于指定的位置即可，从而实现SPS PDSCH对应的HARQ-ACK的反馈。
增强动态码本支持的PDSCH分组最大数目M可以由协议规定或根据实际需要进行设置，上述N2基于N1个SPS PDSCH归属的PDSCH分组情况确定，N2<＝M。本发明实施例中，以N2＝2为例进行详细说明。此时上述N2个第一PDSCH分组可以包括PDSCH分组0和PDSCH分组1，基于N1个SPS PDSCH归属的第一PDSCH分组可以确定N2个第一比特序列包括比特序列0和比特序列1，其中，比特序列0与PDSCH分组0对应，比特序列1与PDSCH分组1对应。
在一可选实施例中，若将所述N2个第一比特序列位于所述目标动态码本的尾部时，可以对比特序列0和比特序列1按照预设的方式进行级联，将级联后的整体比特序列置于目标动态码本的尾部。该目标动态码本可以仅包括该比特序列0和比特序列1，当然除了包括比特序列0和比特序列1之外，还可以包括DCI对应的HARQ-ACK。这里的DCI可以包括调度PDSCH传输的DCI，以及指示SPS PDSCH释放的DCI，每个DCI中都会指示C-DAI，在一些情况下还会指示T-DAI。此时，该比特序列0和比特序列1级联后的整体比特序列位于DCI对应的HARQ-ACK构成的比特序列的后面。换句话说，在本发明实施例中，在所述N2个第一比特序列位于所述目标动态码本的尾部的情况下，所述目标动态码本仅包括所述第一比特序列，或者，所述目标动态码本包括所述第一比特序列以及第二比特序列，所述第二比特序列与所述目标动态码本承载的HARQ-ACK对应的所有PDSCH分组中下行控制信息DCI对应。应理解，目标动态码本中与DCI对应的PDSCH的分组可不包括上述第一PDSCH分组，也可以包括部分或者全部的第一PDSCH分组，在此不做进一步的限定。
在另一可选实施例中，若将所述第一比特序列位于目标PDSCH分组对应的目标比特序列的尾部时，可以理解为将比特序列0置于PDSCH分组0对应的目标比特序列的尾部，将比特序列1置于PDSCH分组1对应的目标比特序列的尾部。需要说明的是，在所述第一比特序列位于目标PDSCH分组对应的目标比特序列的尾部的情况下，所述目标比特序列仅包括所述第一比特序列，或者所述目标比特序列包括所述第一比特序列以及第三比特序列，所述第三比特序列与所述第一比特序列对应的第一PDSCH分组中下行控制信 息DCI对应。例如，上述PDSCH分组0可以包括或者不包括DCI对应的HARQ-ACK，上述PDSCH分组1可以包括或者不包括DCI对应的HARQ-ACK。以PDSCH分组0不包括DCI对应的HARQ-ACK，PDSCH分组1包括DCI对应的HARQ-ACK的情况进行说明，此时PDSCH分组0对应的目标比特序列仅包括比特序列0，PDSCH分组1对应的目标比特序列包括比特序列1以及PDSCH分组1中DCI对应的HARQ-ACK构成的比特序列，且比特序列1位于PDSCH分组1中DCI对应的HARQ-ACK构成的比特序列之后。
本发明实施例中，通过对SPS PDSCH归属的PDSCH分组进行定义，该PDSCH分组用于确定SPS PDSCH对应的HARQ-ACK比特，并将SPS PDSCH对应的HARQ-ACK比特序列基于PDSCH分组设置在动态码本中。这样，本发明实施例实现了将SPS PDSCH对应的HARQ-ACK纳入了PDSCH分组设计框架，可以支持SPS PDSCH对应的HARQ-ACK的反馈，提高了HARQ-ACK的传输可靠性以及可扩展性。
需要说明的是，对于N1个SPS PDSCH归属的PDSCH分组的确定方式可以根据实际需要进行设置，例如，在本发明实施例中，所述确定N1个SPS PDSCH归属的N2个第一PDSCH分组包括以下任一项：
确定所述N1个SPS PDSCH归属的第一PDSCH分组为默认PDSCH分组；
根据激活所述SPS PDSCH的DCI，确定所述SPS PDSCH归属的第一PDSCH分组。
其中，上述默认分组可以为PDSCH分组0，此时，可以认为N1个SPS PDSCH统一归属于PDSCH分组0。激活所述SPS PDSCH的DCI通常包括两种类型的DCI，例如，通常包括回退DCI和非回退DCI，在非回退DCI中通常包括PDSCH分组指示，因此，在本发明实施例中，可以基于DCI的类型确定SPS PDSCH归属的PDSCH分组。具体地，在本发明实施例中，所述根据激活所述SPS PDSCH的DCI，确定所述SPS PDSCH归属的第一PDSCH分组包括：
在所述DCI为非回退DCI的情况下，确定所述SPS PDSCH归属的第一 PDSCH分组为所述非回退DCI指示的PDSCH分组；
在所述DCI为回退DCI的情况下，确定所述SPS PDSCH归属的第一PDSCH分组为默认PDSCH分组。
本发明实施例针对回退DCI激活的SPS PDSCH和非回退DCI激活的SPS PDSCH按照不同的方式确定其归属PDSCH分组，从而提高了PDSCH分组的灵活性。
在本发明实施例中，对于第一比特序列的位置定义包括以下两种方案。
方案1：第一比特序列位于所述目标动态码本的尾部；
方案2：第一比特序列位于目标分组对应的目标比特序列的尾部。
针对方案1，在第一比特序列的数量为1(即N2＝1)的情况下，直接将第一比特序列设置在目标动态码本的尾部。在N2大于1(即所述第一比特序列的数量大于1)的情况下，所述N2个第一比特序列可以按照PDSCH分组的组号增序方式进行级联。
针对上述方案2，可以理解为，每一第一比特序列都位于对应的目标比特序列的尾部，换句话说，每一PDSCH分组对应的SPS PDSCH所对应的HARQ-ACK位于该PDSCH分组所对应的HARQ-ACK比特序列的尾部。
对于上述方案1和方案2中第一比特序列的组成可以考虑同一PDSCH分组包括由一个或者多个服务小区发送的SPS PDSCH的情况，以及同一服务小区发送的SPS PDSCH归属于1项或者多项SPS配置的情况，以下针对各种情况对第一比特序列的组成进行详细说明。
可选地，在一实施例中，所述第一比特序列满足：
在所述第一比特序列对应的SPS PDSCH属于单个服务小区的情况下，所述第一比特序列为第四比特序列，所述第四比特序列由服务小区内的SPS PDSCH对应的HARQ-ACK确定；
在所述第一比特序列对应的SPS PDSCH属于L个服务小区的情况下，所述第一比特序列由L个第四比特序列进行级联得到，所述第四比特序列由同一服务小区内的SPS PDSCH对应的HARQ-ACK确定，L为大于1的整数。
其中，所述第一比特序列由所述L个第四比特序列按照服务小区的索引 排序依次级联得到。例如，可以采用基于服务小区索引升序进行级联。例如，L个第四比特序列包括比特序列0a和比特序列0b，其中，比特序列0a对应服务小区0，比特序列0b对应服务小区1。此时，比特序列0a和比特序列0b按照服务小区索引级联后，比特序列0a位于比特序列0b之前。应理解，在其他实施例中，所述第一比特序列可以由所述L个第四比特序列基于服务小区索引降序进行级联依次级联得到。
可选地，本发明实施例中，可以考虑需要反馈HARQ-ACK的N1个SPS PDSCH在某个服务小区s上发送的SPS PDSCH归属于一到多项下行SPS配置，每项下行SPS配置对应一个配置索引，此配置索引在此服务小区s的激活BWP范围内唯一标识此项下行SPS配置。此时针对单个服务小区的SPS PDSCH对应的第四比特序列可以考虑按照以下方式确定。
在一实施例中，上述第四比特序列满足以下至少之一：
在所述第四比特序列对应的第一SPS PDSCH属于J项SPS配置，且J为1的情况下，所述第四比特序列为第五比特序列，所述第五比特序列为所述第一SPS PDSCH对应的HARQ-ACK按照SPS PDSCH的开始传输时刻的先后顺序排列得到；
在所述第四比特序列对应的第一SPS PDSCH属于J项SPS配置，且J为大于1的整数的情况下，所述第四比特序列由J个第五比特序列级联得到，所述第五比特序列为同一SPS配置的所述第一SPS PDSCH对应的HARQ-ACK，按照SPS PDSCH的开始传输时刻的先后顺序排列得到。
上述J个第五比特序列级联的顺序可以为按照SPS配置的配置索引升序级联。换句话说，在本实施例中，可以先遍历单项下行SPS配置的SPS PDSCH的开始传输时刻(可选地，可以按SPS PDSCH传输时刻从前至后排列)，然后遍历各项下行SPS配置(可选地，可以按下行SPS配置索引从小到大排列)。例如，在本实施例中，上述第四比特序列对应的第一SPS PDSCH的数量为4个，对应的包括4个比特的HARQ-ACK(以A、B、C和D表示4个第一SPS PDSCH对应的4个HARQ-ACK比特)，其中，A和B对应的第一SPS PDSCH归属于SPS配置1；C和D对应的第一SPS PDSCH归属于SPS配置2；与A对应的第一SPS PDSCH的开始传输时刻为时刻1，与B对应的 第一SPS PDSCH的开始传输时刻为时刻2，与C对应的第一SPS PDSCH的开始传输时刻为时刻3，与D对应的第一SPS PDSCH的开始传输时刻为时刻4，各开始传输时刻从先到后的排列顺序为：时刻2、时刻3、时刻1、时刻4。此时，首先遍历单项下行SPS配置的SPS PDSCH的开始传输时刻得到单项下行SPS配置对应的第五比特序列包括BA和CD，然后遍历各项下行SPS配置，即将两个第五比特序列按照配置索引升序级联得到第四比特序列(即BACD)。应理解，在其他实施例中，上述J个第五比特序列级联的顺序也可以为按照SPS配置的配置索引降序级联。
在另一实施例中，所述第四比特序列满足以下至少之一：
在所述第四比特序列对应的第一SPS PDSCH的开始传输时刻位于1个时隙的情况下，所述第四比特序列为第六比特序列，所述第六比特序列为所述第一SPS PDSCH对应的HARQ-ACK按照SPS配置索引的顺序排列得到；
在所述第四比特序列对应的第一SPS PDSCH的开始传输时刻位于K个时隙的情况下，所述第四比特序列由K个第六比特序列级联得到，所述第六比特序列为同一时隙的所述第一SPS PDSCH对应的HARQ-ACK按照SPS配置索引的顺序排列得到。
上述第六比特序列级联的顺序可以为按照时隙的先后顺序级联。换句话说，本实施例中，可以理解为先遍历各传输时隙内各项下行SPS配置(典型地，可以按下行SPS配置索引从小到大排列)，然后遍历各个传输时隙(仅存在SPS PDSCH传输且其HARQ-ACK需要在动态码本中反馈的时隙才作为传输时隙纳入遍历；典型地，可以按传输时隙与动态码本传输时隙之间的时间间隔从大到小排序，换句话说，按传输时隙的开始时刻从前往后排列)。
例如，在本实施例中，上述第四比特序列对应的第一SPS PDSCH的数量为4个，对应的包括4个比特的HARQ-ACK(以A、B、C和D表示4个第一SPS PDSCH对应的4个HARQ-ACK比特)，其中，A和B对应的第一SPS PDSCH归属于SPS配置1；C和D对应的第一SPS PDSCH归属于SPS配置2；与A对应的第一SPS PDSCH的开始传输时刻为时刻1，与B对应的第一SPS PDSCH的开始传输时刻为时刻2，与C对应的第一SPS PDSCH的开始传输时刻为时刻3，与D对应的第一SPS PDSCH的开始传输时刻为时刻4， 各开始传输时刻从先到后的排列顺序为：时刻2、时刻3、时刻1、时刻4，且时刻2和时刻3位于时隙1，时刻1和时刻4位于时隙2，时隙2位于时隙1之后。此时，首先遍历传输时隙内的各项SPS配置得到每一时隙对应的第六比特序列(BC和AD)，然后再遍历各个时隙得到第四比特序列(即BCAD)。
在另一实施例中，所述第四比特序列由同一服务小区内的SPS PDSCH对应的HARQ-ACK按照SPS PDSCH的开始传输时刻的先后顺序排列得到。
本实施例中，可以直接遍历SPS PDSCH的传输开始时刻，不区分各SPS PDSCH具体对应于哪项下行SPS配置，这里假设对于单个服务小区的激活BWP(任意时刻单个服务小区只存在单个处于激活状态的BWP)，任意两次SPS PDSCH传输的持续时间不存在任何时域交叠。例如，在本实施例中，上述第四比特序列对应的第一SPS PDSCH的数量为4个，对应的包括4个比特的HARQ-ACK(以A、B、C和D表示4个第一SPS PDSCH对应的4个HARQ-ACK比特)，其中，与A和B对应的第一SPS PDSCH归属于SPS配置1；与C和D对应的第一SPS PDSCH归属于SPS配置2；与A对应的第一SPS PDSCH的开始传输时刻为时刻1，与B对应的第一SPS PDSCH的开始传输时刻为时刻2，与C对应的第一SPS PDSCH的开始传输时刻为时刻3，与D对应的第一SPS PDSCH的开始传输时刻为时刻4，各开始传输时刻从先到后的排列顺序为：时刻2、时刻3、时刻1、时刻4。经过遍历可以直接得到第四比特序列为BCAD。
进一步需要说明的是，一个PDSCH分组内需要反馈HARQ-ACK的SPS PDSCH的确定可以采用以下方式中的一种进行确定：
方式1：所述N1个SPS PDSCH对应的HARQ-ACK反馈时隙与所述目标动态码本的传输时隙相同。
方式2：目标SPS PDSCH的开始传输时刻位于目标时间段内。
其中，所述目标SPS PDSCH为所述N1个SPS PDSCH中的任一个SPS PDSCH，所述目标时间段的开始时刻为所述目标SPS PDSCH归属的第一PDSCH分组中，距离所述目标动态码本的开始传输时刻最近的NFI翻转时刻，所述NFI翻转时刻位于所述目标动态码本的开始传输时刻之前。
可选地，所述目标时间段的结束时刻包括以下任一项：
所述目标动态码本的开始传输时刻；
在所述目标动态码本的开始传输时刻之前，且与所述目标动态码本的开始传输时刻间隔预设时长。
针对上述方式1，本发明实施例可以理解为：仅考虑HARQ-ACK的反馈时隙与目标动态码本传输时隙重合的SPS PDSCH对应的HARQ-ACK。可选地，可以基于激活该SPS PDSCH的DCI确定SPS PDSCH对应的HARQ-ACK的反馈时隙。
针对上述方式2，本发明实施例可以理解为考虑从SPS PDSCH所属PDSCH分组的最近一次NFI翻转开始(例如，将SPS PDSCH所属PDSCH分组中距离目标动态码本传输最近一次NFI翻转时的系统时刻作为参考时刻，将传输起始时间在参考时刻之后且归属于此PDSCH分组的SPS PDSCH都纳入反馈范围)，直至指定结束时刻(即上述目标时间段的结束时刻)之内所有SPS PDSCH对应的HARQ-ACK。对于这些SPS PDSCH，其对应的NFI可以认为就是最近一次NFI翻转之后的NFI值，此NFI值与SPS PDSCH所属PDSCH分组对应。
其中，上述指定结束时刻可以采用如下某种方式确定：
最晚SPS PDSCH对应的HARQ-ACK反馈时隙(即基于SPS PDSCH传输所在时隙n与HARQ-ACK反馈时隙偏移k确定的HARQ-ACK反馈时隙n+k)不晚于动态码本传输时隙。
最晚SPS PDSCH的结束时刻与动态码本传输所在的PUCCH或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的开始时刻之间的时间间隔不小于预设值。该预设值可以由终端的能力确定，例如对应N1个符号的时长(可选地进一步考虑定时提前TA的影响)，也可以是协议约定，还可以是网络设备配置，在此不做进一步的限定。
上述NFI翻转时刻的确定方式包括以下至少一项：
根据DCI显式指示的NFI确定；本实施例可以理解为：根据所述目标SPS PDSCH归属的第一PDSCH分组中，距离所述目标动态码本的开始传输时刻最近一次显式指示的NFI来确定；当此显式指示的NFI和所述目标SPS PDSCH归属的第一PDSCH分组在显式指示之前对应的NFI的取值不同时， 可以认为NFI发生翻转，此显式指示所在传输的传输时刻，或者所在传输的开始传输时刻，可以作为NFI翻转时刻。例如，通过在调度此PDSCH分组的PDSCH传输的non-fallback DCI中的指示确定，当基于某一non-fallback DCI中指示的NFI判断NFI发生翻转时，此non-fallback DCI的发送时刻，或者开始发送时刻，可以作为NFI翻转时刻。
根据协议约定的NFI翻转规则确定。例如，某次动态码本传输对于某个PDSCH分组只对应fallback DCI调度的PDSCH传输或指示的SPS PDSCH释放时，假设从这些fallback DCI的第一个开始，此PDSCH分组的NFI发生了翻转。此时这里的第一个fallback DCI的发送时刻，或者开始发送时刻，可以作为NFI翻转时刻。
需要说明的是，不同的PDSCH分组对应的NFI翻转时刻可以不同。
进一步地，在执行步骤201之前还需要考虑目标动态码本包括的HARQ-ACK，即需要首先确定需要传输的SPS PDSCH对应的HARQ-ACK以及DCI调度的PDSCH或指示的SPS PDSCH释放对应的HARQ-ACK。
例如，在一实施例中，所述步骤201之前，该方法还包括：
步骤203，在所述目标动态码本对应的目标传输时隙与所述N1个SPS PDSCH中的部分或全部SPS PDSCH对应的HARQ-ACK的反馈时隙相同的情况下，确定所述N1个SPS PDSCH包括HARQ-ACK的反馈时隙位于所述目标传输时隙内的SPS PDSCH。SPS PDSCH对应的HARQ-ACK的反馈时隙由激活此SPS PDSCH的DCI确定。
可选地，所述N1个SPS PDSCH还包括开始传输时刻位于所述目标时间段内的SPS PDSCH。
进一步地，所述确定所述N1个SPS PDSCH包含HARQ-ACK的反馈时隙位于所述目标传输时隙内的SPS PDSCH之后所述方法还包括：
步骤204，将DCI对应的第一HARQ-ACK确定为所述目标动态码本中除所述第一比特序列之外的HARQ-ACK；
其中，所述第一HARQ-ACK满足以下任一项：
所述第一HARQ-ACK的反馈时隙与所述目标传输时隙相同；
在所述终端配置了预设参数的情况下，所述第一HARQ-ACK为基于所 述N1个SPS PDSCH触发重传的HARQ-ACK。
其中，上述预设参数可以为SPS-PUCCH-AN-List。
所述基于所述N1个SPS PDSCH触发重传的HARQ-ACK，可以理解为，对应的HARQ-ACK的反馈时隙与目标传输时隙相同的SPS PDSCH的HARQ-ACK传输，可以触发此SPS PDSCH所归属的PDSCH分组与DCI对应的HARQ-ACK的重传，这些HARQ-ACK都包含在目标动态码本中。
可选地，在本实施例中，在所述终端配置了预设参数的情况下，所述目标动态码本的传输资源为所述预设参数对应的资源列表中的资源。
进一步地，在另一实施例中，上述步骤201之前，所述方法还包括：
步骤205，在所述目标动态码本对应的目标传输时隙与所述N1个SPS PDSCH对应的HARQ-ACK的反馈时隙均不同的情况下，所述N1个SPS PDSCH包括第二HARQ-ACK对应的第一PDSCH分组内的SPS PDSCH，所述第二HARQ-ACK为DCI对应的HARQ-ACK中，反馈时隙与所述目标传输时隙相同的HARQ-ACK。这里的反馈时隙与所述目标传输时隙相同，可以理解为，当需要在所述目标动态码本中包含一个或多个第一PDSCH分组的DCI对应的HARQ-ACK时，这些HARQ-ACK的反馈时隙与所述目标传输时隙相同。
为了更好的理解本发明的具体实现，以下针对本发明的具体实现过程进行详细说明。
本发明实施中，SPS PDSCH无对应的DAI，其中SPS PDSCH统一归属于PDSCH分组0，或者，当由Non-fallback DCI激活SPS PDSCH传输时，归属于此Non-fallback DCI中指示的PDSCH分组，当由Fallback DCI激活SPS PDSCH传输时，归属于默认分组，即PDSCH分组0。
具体的传输方案可以包括以下方案一和方案二。
方案一：SPS PDSCH对应的HARQ-ACK比特总是附在整个动态码本增强的尾部进行传输。
如图3所示，动态码本增强划分为第一部分(即靠前的部分)和第二部分(即靠后的部分)，第一部分为与DCI对应的HARQ-ACK比特序列(即涉及n0(＝0～M)个PDSCH分组的与DCI对应的HARQ-ACK比特序列)，第二 部分为与SPS PDSCH对应的HARQ-ACK比特序列(即涉及n1(＝0～M)个PDSCH分组的与SPS PDSCH对应的HARQ-ACK比特序列)。其中，M为假设允许或可配置的PDSCH分组最大数目。应理解，在图3中，虚线框表示当存在对应的比特序列时，该比特序列与其他比特序列的相对位置关系，在实际传输中，针对某一PDSCH分组，与DCI对应的或与SPS PDSCH对应的HARQ-ACK比特序列并不一定总是传输。换句话说，针对某一PDSCH分组，可能包括与DCI对应的HARQ-ACK比特序列和/或与SPS PDSCH对应的HARQ-ACK比特序列，还有可能不存在与之对应的HARQ-ACK比特序列。以下针对第一部分和第二部分不一定同时存在的情况进行详细说明：
情况1：当SPS PDSCH HARQ-ACK单独传输时，即在图3中仅传输第二部分(n0＝0，n1>0)时，可以作如下处理：
情况1-1：当只涉及单个PDSCH分组的SPS PDSCH HARQ-ACK(即n1＝1)时，只传输此PDSCH分组的SPS PDSCH HARQ-ACK比特序列。
情况1-2：当涉及大于一个PDSCH分组的SPS PDSCH HARQ-ACK(即n1>1)时，将各个PDSCH分组的SPS PDSCH HARQ-ACK比特序列按预定义的顺序进行级联，得到待传输的SPS PDSCH HARQ-ACK比特序列。预定义的顺序可以为基于PDSCH分组的组号进行增序排列。
情况2：当SPS PDSCH HARQ-ACK和其它基于DCI的HARQ-ACK一起传输时，即在图3中同时传输第一部分和第二部分(n0>0，n1>0；动态码本增强涉及的某个PDSCH分组不一定同时包含与DCI对应的HARQ-ACK比特序列和与SPS PDSCH对应的HARQ-ACK比特序列)时，可以作如下处理：
按情况1-1或情况1-2中的处理，得到待传输的SPS PDSCH HARQ-ACK比特序列，并附在基于DCI确定的动态码本增强之后进行传输。
可选地，某个PDSCH分组的SPS PDSCH HARQ-ACK比特序列的确定，或者，当配置了多个服务小区时，某个PDSCH分组针对某个服务小区的SPS PDSCH HARQ-ACK比特序列的确定，可以采用如下某种方式：
方式1：仅考虑HARQ-ACK反馈时隙与码本传输时隙重合的SPS PDSCH对应的HARQ-ACK。
方式2：考虑从SPS PDSCH所属PDSCH分组的最近一次NFI翻转开始(例如，将SPS PDSCH所属PDSCH分组最近一次NFI翻转时的系统时刻作为参考时刻，将起始时间在参考时刻之后且归属于此PDSCH分组的SPS PDSCH都纳入反馈范围)，直至指定结束时刻之内所有SPS PDSCH对应的HARQ-ACK。对于这些SPS PDSCH，其对应的NFI可以认为就是最近一次NFI翻转之后的NFI值。
其中，指定结束时刻可以采用如下某种方式：
最晚SPS PDSCH对应的HARQ-ACK反馈时隙(即基于SPS PDSCH传输所在时隙n与HARQ-ACK反馈时隙偏移k确定的HARQ-ACK反馈时隙n+k)不晚于动态码本传输时隙；
最晚SPS PDSCH的结束时刻与动态码本传输的PUCCH或PUSCH开始时刻之间的时间间隔不小于预设值。该预设值可以由终端的能力确定，也可以是协议约定，还可以是网络设备配置，在此不做进一步的限定。
上述SPS PDSCH所属PDSCH分组的最近一次NFI翻转，可以由如下方式a或方式a+方式b确定：
方式a：基于此PDSCH分组中DCI显式指示的NFI确定。具体地，可以基于此PDSCH分组最近显式指示的NFI(例如，在调度此PDSCH分组的PDSCH传输的non-fallback DCI中指示)来确定。这里的最近，可以理解为在时间上距离动态码本传输时隙最近。
方式b：基于其它预定义的规则确定(例如，某次动态码本传输对于某个PDSCH分组只对应fallback DCI调度的PDSCH传输或指示的SPS PDSCH释放时，假设从这些fallback DCI的第一个开始，此PDSCH分组的NFI发生了翻转)。
可选地，对于上述任一种方式(即方式1或方式2)，假设需要反馈HARQ-ACK的SPS PDSCH归属于一到多项下行SPS配置，每项下行SPS配置对应一个配置索引，此配置索引可在单个服务小区的激活BWP范围内唯一标识此项下行SPS配置。此时针对单个服务小区的SPS PDSCH HARQ-ACK比特序列的确定，可以采用如下操作：
方式I：先遍历单项下行SPS配置纳入反馈范围的SPS PDSCH的传输时 刻(典型地，可以按SPS PDSCH传输时刻从前至后排列)，然后遍历各项下行SPS配置(典型地，可以按下行SPS配置索引从小到大排列)。
方式II：先遍历某个传输时隙内(可能存在的)各项下行SPS配置(典型地，可以按下行SPS配置索引从小到大排列)，然后遍历各个传输时隙(仅存在SPS PDSCH传输且其HARQ-ACK需要在动态码本中反馈的时隙才作为传输时隙纳入遍历；典型地，可以按传输时隙与动态码本传输时隙之间的时间间隔从大到小排序)。
方式III：直接遍历SPS PDSCH的传输开始时刻，不区分各SPS PDSCH具体对应于哪项下行SPS配置，这里假设对于单个服务小区的激活BWP(任意时刻单个服务小区只存在单个处于激活状态的BWP)，任意两次SPS PDSCH传输的持续时间不存在任何时域交叠。
需要说明的是，当某个PDSCH分组涉及多个服务小区上的SPS PDSCH对应的HARQ-ACK需要反馈时，先按上述操作确定各服务小区对应的SPS PDSCH HARQ-ACK比特序列，然后将各服务小区对应的SPS PDSCH HARQ-ACK比特序列按照服务小区索引依次级联，并将级联后的HARQ-ACK比特序列按情况1或情况2进行传输。这里按照服务小区索引依次级联，典型情况下，可以基于服务小区索引升序级联。
方案二：SPS PDSCH对应的HARQ-ACK比特总是附在其归属的PDSCH分组对应的动态码本(该动态码本可以理解为PDSCH分组对应的比特序列，并非实际传输定义的码本)的尾部进行传输。
如图4所示，虚线框表示当存在对应的比特序列时，该比特序列与其他比特序列的相对位置关系，在实际传输中，针对某一PDSCH分组中，与DCI对应的或与SPS PDSCH对应的HARQ-ACK比特序列并不一定总是传输。换句话说，针对某一PDSCH分组，可能包括与DCI对应的HARQ-ACK比特序列和/或与SPS PDSCH对应的HARQ-ACK比特序列，还有可能不存在与之对应的HARQ-ACK比特序列。动态码本增强对应的HARQ-ACK比特序列包含n(n>0)个PDSCH分组对应的HARQ-ACK比特序列。为了描述方便，假设M为允许或可配置的PDSCH分组最大数目，m为每个PDSCH分组的索引或组号，m>＝0且m<＝(M–1)。对于PDSCH分组m，使用g(m,0)和 g(m,1)分别指示此PDSCH分组与DCI对应的HARQ-ACK比特序列和与SPS PDSCH对应的HARQ-ACK比特序列是否包含在最终传输的动态码本增强中，g(m,0)和g(m,1)的取值都为0或1，g(m)为g(m,0)与g(m,1)的逻辑或，用于指示PDSCH分组m对应的HARQ-ACK比特序列是否包含在最终传输的动态码本增强中，g(m)＝0表示不包含，g(m)＝1表示包含。则图4中，

当SPS PDSCH HARQ-ACK单独传输(即n0＝0，n1>0)时，和方案一中情况1的操作及传输的SPS PDSCH HARQ-ACK比特序列完全一致。
当SPS PDSCH HARQ-ACK和其它基于DCI的HARQ-ACK一起传输(即n0>0，n1>0)时，顺序执行如下操作：
第一步：执行方案一中的对应操作，确定需要反馈HARQ-ACK的各个PDSCH分组对应的SPS PDSCH HARQ-ACK比特序列。
第二步：确定各个PDSCH分组对应的HARQ-ACK比特序列，可以区分如下情况：
当某个PDSCH分组只需反馈SPS PDSCH对应的HARQ-ACK时，此PDSCH分组对应的HARQ-ACK比特序列即为此PDSCH分组对应的SPS PDSCH HARQ-ACK比特序列。
当某个PDSCH分组需要同时反馈SPS PDSCH对应的HARQ-ACK，以及其它基于DCI的HARQ-ACK时，将此PDSCH分组对应的SPS PDSCH HARQ-ACK比特序列逐比特级联在基于DCI确定的HARQ-ACK比特序列之后。
进一步需要说明的是，上述SPS PDSCH对应的HARQ-ACK的传输方案，从最终需要在某个PUCCH或码本传输上承载的HARQ-ACK范围或情况来考虑如何组织动态码本(即最终传输的HARQ-ACK比特序列)。下面简单分析导致前述各种HARQ-ACK承载范围或情况的场景。
需要传输某个PDSCH分组对应的SPS PDSCH HARQ-ACK的场景包括：
情况a：SPS PDSCH的HARQ-ACK在其对应的反馈时隙内传输。这里可以进一步区分如下三种传输情况：
情况a-1：在反馈时隙内单独传输SPS PDSCH HARQ-ACK，并不涉及同 一PDSCH分组内其它与DCI对应的HARQ-ACK的传输(对应于下述规则1)。
情况a-2：在反馈时隙内单独传输SPS PDSCH HARQ-ACK，并基于某种规则(对应于下述规则2)触发了同一PDSCH分组内其它DCI对应的HARQ-ACK的重传。当同一PDSCH分组不存在任何DCI对应的HARQ-ACK反馈时隙与SPS PDSCH HARQ-ACK反馈时隙重合(重合时对应于HARQ-ACK初传)时，应用如下某种规则：
规则1：某个PDSCH分组的SPS PDSCH的HARQ-ACK反馈，总是不触发此PDSCH分组其它DCI对应的HARQ-ACK的重传。
规则2：当为UE配置了参数SPS-PUCCH-AN-List时，某个PDSCH分组的SPS PDSCH的HARQ-ACK反馈，可以触发此PDSCH分组其它DCI对应的HARQ-ACK的重传；此时根据待传输的HARQ-ACK比特数选择参数SPS-PUCCH-AN-List对应的PUCCH资源列表中的某个PUCCH资源。
情况a-3：在反馈时隙内传输SPS PDSCH HARQ-ACK，同时同一PDSCH分组内其它与DCI对应的HARQ-ACK也对应于此反馈时隙(通过DCI中的“PDSCH-to-HARQ_feedback timing indicator”指示域确定其对应的HARQ-ACK反馈时隙)。
情况b：在传输(包括初次传输和触发重传)SPS PDSCH所属的PDSCH分组的与DCI对应的HARQ-ACK时，捎带传输SPS PDSCH HARQ-ACK。
应理解，上述情况a-1可以理解为终端执行上述步骤203中的操作，上述情况a-2和a-3可以理解为终端执行上述步骤204中的操作，上述情况b可以理解为终端执行上述步骤205中的操作。
上述情况a-2、情况a-3和情况b最终使得针对某一PDSCH分组，SPS PDSCH HARQ-ACK和其它基于DCI的HARQ-ACK一起传输，情况a-1则针对某一PDSCH分组仅传输SPS PDSCH HARQ-ACK。
如果某一动态码本增强传输涉及的所有PDSCH分组(单个或多个PDSCH分组)都仅传输SPS PDSCH HARQ-ACK，则对应前述情况1；只要有至少一个PDSCH分组的SPS PDSCH HARQ-ACK和其它基于DCI的HARQ-ACK一起传输，则对应前述情况2。
