具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在对本申请实施例提供的HARQ-ACK码本的反馈方法进行详细介绍之前，先对本申请实施例涉及的相关知识、应用场景和实施环境进行简单介绍。
首先，对本申请提供的专业术语进行简单介绍。
HARQ：该机制可以使用停等协议(Stop-and-Wait Protocol，也称SQW协议)来发送数据。在停等协议中，发送端在使用一个HARQ进程来发送传输块(Transmission Block，TB)之后，就停下来等待反馈信息，该过程也可称为HARQ过程。如此使得发送端在发送TB之后，均会停下来等待确认。然而，上述方式容易导致用户吞吐量很低，因此，为了提高用户吞吐量，可以采用多个并行的HARQ进程进行TB发送，当一个HARQ进程在等待反馈信息时，发送端可以使用另一个HARQ进程来继续发送TB。这些HARQ进程共同组成了一个HARQ实体，每个HARQ实体负责维护一组并行的下行HARQ进程和一组并行的上行HARQ进程，该HARQ实体结合了停等协议，允许数据块进行连续发送。在HARQ过程中，反馈信息包括肯定应答ACK信息或否定应答NACK(Negative acknowledgement)信息，若确认接收成功则该反馈信息为ACK，如果确认接受失败则该反馈信息为NACK。其中，包括ACK信息或NACK信息的反馈序列可以称为HARQ-ACK码本。
one-shot HARQ-ACK码本反馈：对于下行传输，又称为type-3 HARQ-ACK码本反馈，可以由网络设备为终端设备配置。如果网络设备为终端设备配置了Type-3 HARQ-ACK码本反馈，网络设备可以通过DCI(Downlink Control Information，下行控制信息)信息触发终端设备进行one-shot HARQ-ACK码本反馈，例如为one-shot HARQ-ACK码本反馈指示有效的PUCCH资源。One-shot HARQ-ACK码本中包括一个PUCCH组中所有配置的载波上的所有HARQ进程对应的反馈信息，该反馈信息包括ACK信息或NACK信息。其中，包括下行传输的HARQ进程，其对应的反馈信息为下行传输的译码结果，没有包括下行传输的HARQ进程，其对应的反馈信息为预设值或初始值。
对于上行传输，如果被配置one-shot HARQ-ACK码本反馈，网络设备可以通过DCI将载波上的所有HARQ进程对应的反馈信息发送给终端设备。其中，包括上行传输的HARQ进程，其对应的反馈信息为上行传输的译码结果，没有包括上行传输的HARQ进程，其对应的反馈信息为预设值或初始值。其中，上行传输包括DCI调度的上行传输和CG(Configured Grant，预配置授权)调度的上行传输。
目前，one-shot HARQ-ACK码本反馈可以包括两种类型，一种是携带NDI(New Data Indication，新数据指示)信息的one-shot HARQ-ACK码本反馈，一种是不携带NDI信息的one-shot HARQ-ACK码本反馈。其中，该NDI信息可以用于确定对应的数据是重传数据还是新数据，通常情况下，当数据为新数据时，当前的NDI信息相对于上一次传输的NDI信息会发生翻转，如此，基于该NDI信息是否发生翻转可以确定数据是新数据还是重传数据。譬如，若上一次传输的NDI信息为“1”，如果当前的NDI信息为“0”，此时可以确定该NDI信息发生了翻转，从而可以确定当前的数据包为新数据包。作为一种示例，网络设备可以通过RRC(Radio Resource Control，无线资源控制)信令来配置终端设备在进行HARQ-ACK码本反馈时是否需要携带NDI信息。
HARQ码本：终端设备在一个HARQ反馈资源上反馈的反馈信息的整体称为HARQ码本(或称HARQ-ACK码本)。在one-shot HARQ-ACK码本反馈中，该HARQ码本包括了一个PUCCH组(或一个小区组)中所有载波的所有HARQ进程对应的反馈信息。
SPS PDSCH(Semi-Persistent Scheduling Physical Downlink Shared Channel，半持续调度物理下行共享信道)：为了支持周期性且业务量基本固定的业务，同时减少频繁的PDCCH(Physical Downlink Control Channel，物理下行控制信道)调度开销，NR系统可以支持半静态的资源配置。其中，半静态的资源配置指的是，网络设备通过高层信令为终端设备半静态配置资源，例如，该高层信令为RRC信令，并在有业务需求时，网络设备通过PDCCH承载的DCI为终端设备激活该半静态的资源配置，从而终端设备可以在每个固定的周期根据该配置资源接收业务数据。
或者说，终端设备可以被配置SPS配置资源，网络设备可以通过激活或去激活的方式来指示终端设备是否在SPS配置资源上进行SPS PDSCH传输。该SPS配置资源可以配置在SpCell上，也可以配置在SCells上。在R15中，网络设备需要保证一个小区组中最多有一个小区配置下行SPS配置资源，随着版本的演进，在一个小区组中可以配置多个下行SPS配置资源。
对于下行SPS配置资源，主要是通过CS-RNTI(Configured Scheduling-Radio Network Tempory  Identity，配置调度-小区无线网络临时标识)扰码的DCI来进行激活和去激活。作为示例，如果终端设备收到CS-RNTI扰码的DCI，并且使能TB对应的NDI域设置为“0”，那么，终端设备根据表1(下行SPS调度激活的PDCCH的特殊域设置)和表2(下行SPS调度释放的PDCCH的特殊域设置)，可以判断是否收到下行SPS调度激活命令或去激活命令(或称，释放命令)。如果终端设备收到一个SPS PDSCH去激活的DCI，则终端设备被期望在N个符号后进行相应的HARQ-ACK反馈，该N个符号是从该SPS PDSCH去激活DCI对应的PDCCH的最后一个符号开始计算。N的取值可以为预设值，该预设值可以根据是基于需求进行设置。

如果终端设备被配置并且激活了下行SPS传输，那么该终端设备在下行SPS配置资源上接收网络设备发送的SPS PDSCH，其中，SPS PDSCH是在下行SPS配置资源上周期性传输的，SPS PDSCH没有对应的PDCCH调度。
由于没有PDCCH调度，下行SPS配置资源上传输的SPS PDSCH只包括初传。如果某个HARQ进程初传失败需要重传，网络设备会通过CS-RNTI扰码的DCI来调度相同的HARQ进程，并将NDI域设置为“1”，或者说，如果终端设备收到CS-RNTI扰码的DCI且NDI域设置为“1”，终端设备会认为该DCI调度的HARQ进程为重传。
CG-PUSCH(Configured Grant Physical Uplink Shared Channel，预配置授权物理上行共享信道)：
为了支持周期性且业务量基本固定的业务，同时减少频繁的PDCCH(Physical Downlink Control Channel，物理下行控制信道)调度开销，NR系统可以支持半静态的上行资源配置。其中，半静态的资源配置指的是，网络设备通过高层信令为终端设备半静态配置资源，例如，该高层信令为RRC信令。在NR系统中，没有动态授权调度的预配置授权上行传输可以通过高层信令半静态配置的CG资源来进行。具体有两种实现方案，即其实际的上行授权可以通过RRC配置(type 1)或通过CS-RNTI扰码的PDCCH(type 2)获得。终端设备在有业务需求时，可以通过该被激活(或被授权)的半静态的资源配置发送业务数据。其中，Type 2的CG-PUSCH资源的激活和去激活方式与SPS PDSCH资源的激活与去激活方式类似。
接下来，对本申请涉及的应用场景进行简单介绍。
在NR系统中，网络设备可以为终端设备配置SPS配置资源(也可称为半静态资源)，并通过激活信令或去激活信令确定是否在SPS配置资源上进行SPS PDSCH传输。如此，如果支持SPS PDSCH传输，同时终端设备被触发进行one-shot HARQ-ACK码本反馈时，如何进行HARQ-ACK信息反馈成为研究的热点，为此，本申请实施例提供了一种HARQ码本反馈方法，其具体实现可以参见下文各个实施例。
另外，对本申请实施例涉及的实施环境进行简单介绍。
本申请实施例的技术方案可以应用于各种通信系统，例如：GSM(Global System of Mobile communication，全球移动通讯)系统、CDMA(Code Division Multiple Access，码分多址)系统、WCDMA(Wideband Code Division Multiple Access，宽带码分多址)系统、GPRS(General Packet Radio Service，通用分组无线业务)、LTE(Long Term Evolution，长期演进)系统、LTE FDD(Frequency Division Duplex，频分双工)系统、LTE TDD(Time Division Duplex，时分双工)系统、LTE-A(Advanced Long Term Evolution，先进的长期演进)系统、NR(New Radio，新无线)系统、NR系统的演进系统、LTE-U(LTE-Based Access To Unlicensed Spectrum，非授权频段上的LTE)系统、NR-U系统、UMTS(Universal Mobile Telecommunication System，通用移动通信系统)、WiMAX(Worldwide Interoperability for Microwave Access，全球互联微波接入)通信系统、WLAN(Wireless Local Area Networks，无线局域网)、WiFi(Wireless Fidelity，无线保真)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，D2D(Device to Device，设备到设备)通信，M2M(Machine to Machine，机器到机器)通信，MTC(Machine Type Communication，机器类型通信)，V2V(Vehicle to Vehicle，车辆间)通信以及V2X(Vehicle To Everything，车联网)系统等。本申请实施例也可以应用于这些通信系统。

也即是，该第一反馈序列中的反馈信息均可以确定对应的HARQ进程号，换句话说，如果可以获 知载波上的HARQ进程的HARQ进程号，则可以通过第一反馈序列来反馈该载波上的HARQ进程对应的反馈信息，譬如，该第一反馈序列可以包括携带有HARQ进程号的DCI调度的PDSCH传输对应的反馈信息。
作为一种示例，该第一反馈序列包括该N个载波上所有HARQ进程基于HARQ进程号排列的反馈信息，该第一反馈序列的排列顺序为先HARQ进程号后载波。示例性的，该第一反馈序列中的反馈信息可以是根据HARQ进程号升序排列的。
譬如，假设该第一反馈序列中包括两个载波上基于HARQ进程号排列的反馈信息，第一个载波上包括16个HARQ进程，第二个载波上包括8个HARQ进程，则在该第一反馈序列对应的码本中，这些反馈信息的排序为，先排第一个载波上的16个HARQ进程对应的反馈信息，然后再排另一个载波上的8个HARQ进程对应的反馈信息。
可选地，一个载波上包括的HARQ进程数可以是网络设备配置的，或者，如果网络设备没有配置，一个载波上包括的HARQ进程数可以为默认值，例如，默认值为8。另外，在本申请中，一个载波可以对应一个小区。
可选地，该N个载波为一个PUCCH组或一个小区组包括的所有载波；或者，该N个载波为一个PUCCH组或一个小区组包括的所有载波中被激活的载波。
也即是，该N可以为网络设备配置的载波个数，或者，也可以为网络设备激活的载波个数，本申请实施例对此不做限定。
可选地，该方法可以由终端设备来执行，确定目标反馈序列可以为终端设备为下行传输确定目标反馈序列。
可选地，该方法可以由终端设备来执行，确定目标反馈序列可以为终端设备为侧行传输确定目标反馈序列。其中，侧行传输可以包括终端设备和终端设备之间的传输，例如V2X等。
可选地，该方法可以由网络设备来执行，确定目标反馈序列可以为网络设备为上行传输确定目标反馈序列。
可选地，如果网络设备配置了包括NDI信息的反馈方式，即网络设备指示终端设备需要反馈NDI信息，则该第一反馈序列还包括每个HARQ进程中的每个TB对应的NDI信息，可选地，该每个HARQ进程中的最大TB个数可以由网络设备进行配置，例如，网络设备可以通过高层信令进行配置，可选地，每个TB对应的NDI信息可以排列在该TB对应的HARQ-ACK反馈信息后面。
可选地，在本申请中，高层信令或高层参数可以包括RRC信息或MAC CE(媒体接入控制单元，Media Access Control Control Element)。
可选地，若网络设备配置包括NDI信息的反馈方式，且该第一反馈序列包括第一HARQ进程对应的第二反馈信息，其中，该第一HARQ进程用于传输SPS PDSCH，则该第二反馈信息包括第一NDI信息，该第一NDI信息为预设值。
也就是说，若配置包括NDI信息的反馈方式，说明需要终端设备反馈NDI信息，如果该第一反馈序列包括用于传输SPS PDSCH的HARQ进程对应的第二反馈信息，则该第二反馈信息中的第一NDI信息可以为预设值，即该预设值可以根据实际需求预先进行设置，也就意味着，如果是HARQ进程用于SPS PDSCH传输，就可以认为所传输的数据为新数据。
例如，第一HARQ进程用于在下行SPS配置资源上传输SPS PDSCH，则第二反馈信息中包括的第一NDI信息的值为“0”；或者，第一HARQ进程用于通过CS-RNTI扰码的DCI来调度SPS PDSCH的重传，则第二反馈信息中包括的第一NDI信息的值为“1”。
又例如，SPS PDSCH的初传HARQ进程对应的NDI信息的值为“0”，或，SPS PDSCH的重传HARQ进程对应的NDI信息的值为“1”。
可选地，若网络设备配置包括NDI信息的反馈方式，第一反馈序列中包括的NDI信息的个数是根据网络设备为该载波配置的最大TB个数来确定的。
可选地，上述至少一个载波可以包括配置半持续调度传输的载波，或者，至少一个载波包括激活半持续调度传输的载波。可选地，上述至少一个载波可以包括配置CG资源传输的载波，或者，至少一个载波包括激活CG资源传输的载波。
可选地，该第二反馈序列包括的反馈信息不是基于HARQ进程号排列的。可选地，该第二反馈序列包括的反馈信息不对应有效的HARQ进程号。可选地，该第二反馈序列包括的反馈信息不对应HARQ进程号。
例如，在一些传输中，网络设备可能不为终端设备指示对应的HARQ进程号，或者为终端设备指示的HARQ进程号不是有效的进程号，譬如，用于指示其他含义。在该种情况下，若该终端设备在反馈第一反馈序列的时间单元上也需要反馈该类传输对应的反馈信息，则无法将该类传输对应的反馈信息 排列到第一反馈序列中的合适位置，为此，终端设备可以通过第二反馈序列对该类传输对应的反馈信息进行反馈。
可选地，该第二反馈序列包括以下情况中的至少一种：
(1)第一DCI对应的反馈信息，该第一DCI为用于指示释放SPS PDSCH的DCI。
例如，该第一DCI是用于去激活SPS配置资源的。目前，该第一DCI中携带的HARQ进程号可以用于指示其他含义，即，实际上该第一DCI中的HARQ进程号是无效的，在该种情况下，通常无法确定该第一DCI对应的HARQ进程号，从而导致可能无法将该第一DCI对应的反馈信息排列到第一反馈序列中的合适位置上，所以，该终端设备可以将该第一DCI对应的反馈信息包括在第二反馈序列中，以通过该第二反馈序列来反馈该第一DCI对应的反馈信息。
可选地，该第一DCI为该N个载波中至少一个载波上用于指示释放SPS PDSCH的DCI；和/或，该第一DCI为用于指示该N个载波中至少一个载波上释放SPS PDSCH的DCI。
例如，该第一DCI可以是至少一个载波上的DCI；也可以是用于指示至少一个载波上释放SPS PDSCH的DCI，即该第一DCI不是至少一个载波上的，本申请实施例对此不做限定。
需要说明的是，上述仅是以该第一DCI中的HARQ进程号当前是无效的为例进行说明，在另一实施例中，若该第一DCI的第一指定域用于携带HARQ进程号，则可以将该第一DCI对应的反馈信息包括在第一反馈序列中，例如，若用于释放SPS PDSCH传输的第一DCI中存在空闲的第一指定域，且该空闲的第一指定域用于携带HARQ进程号，则该终端设备可以基于空闲的第一指定域中的HARQ进程号，将该第一DCI对应的反馈信息排至第一反馈序列中，本申请实施例对此不作限定。
还需要说明的是，这里仅是以半静态的配置资源包括SPS PDSCH为例进行说明，在另一实施例中，半静态的配置资源还可以包括CG-PUSCH，在又一实施例中，半静态的配置资源还可以包括SPS PDSCH和CG-PUSCH，下文也是同理，本申请实施例对此不作限定。
(2)第二DCI对应的反馈信息，或，该第二DCI调度的SPS PDSCH对应的反馈信息，该第二DCI为用于指示激活SPS PDSCH的DCI。
目前，用于指示激活SPS PDSCH的第二DCI中没有用到HARQ进程号，但是第二DCI激活的SPS PDSCH对应预设的HARQ进程号，例如SPS PDSCH对应的HARQ进程号是根据传输该SPS PDSCH的资源确定的。所以，一种可选的实现方式中，终端设备可以将第二DCI对应的反馈信息通过第二反馈序列进行反馈，即该第二反馈序列包括第二DCI对应的反馈信息。或者，终端设备可以将该第二DCI调度的SPS PDSCH对应的反馈信息通过第二反馈序列进行反馈，即该第二反馈序列包括该第二DCI调度的SPS PDSCH对应的反馈信息。另一种可选的实现方式中，终端设备可以根据预设的HARQ进程号将该第二DCI对应的反馈信息排至第一反馈序列中；或者，终端设备可以根据预设的HARQ进程号将该第二DCI调度的SPS PDSCH对应的反馈信息排至第一反馈序列中。
需要说明的是，若该第二DCI中的第二指定域携带HARQ进程号，则可以将该第二DCI对应的反馈信息排至第一反馈序列中；或者，若该第二DCI中的第二指定域携带HARQ进程号，则可以将该第二DCI调度的SPS PDSCH对应的反馈信息排至第一反馈序列中。
(3)第三DCI调度的物理信道对应的反馈信息，第三DCI中不包括HARQ进程号，或，第三DCI中不包括有效的HARQ进程号。
在URLLC(Ultra Reliable Low Latency Communications，超可靠和低延迟通信)中引入了一种DCI调度方式，即该DCI中可以没有HARQ进程号的指示，在该种情况下，可以通过第二反馈序列来反馈第三DCI对应的反馈信息或反馈第三DCI调度的物理信道对应的反馈信息，示例性的，该第三DCI调度的物理信道可以包括PDSCH或PUSCH。
另外，在一些场景中，该第三DCI中携带有HARQ进程号，但该第三DCI中携带的HARQ进程号用于指示其他含义，即该第三DCI中的HARQ进程号不是有效的，在该种情况下，可以通过第二反馈序列来反馈第三DCI对应的反馈信息或反馈第三DCI调度的物理信道对应的反馈信息。
(4)该至少一个载波上传输的无DCI调度的SPS PDSCH对应的反馈信息。
由于无DCI调度，从而无DCI指示SPS PDSCH对应的HARQ进程号，所以SPS PDSCH对应预设的HARQ进程号，例如SPS PDSCH对应的HARQ进程号是根据传输该SPS PDSCH的资源确定的。所以，一种可选的实现方式中，终端设备可以将该至少一个载波上传输的无DCI调度的SPS PDSCH对应的反馈信息通过第二反馈序列进行反馈。另一种可选的实现方式中，终端设备可以根据预设的HARQ进程号将该无DCI调度的SPS PDSCH对应的反馈信息排至第一反馈序列中。
可选地，若网络设备配置包括NDI信息的反馈方式，则该第二反馈序列中还包括NDI信息，该NDI信息为预设值。例如，该NDI信息预设为值“0”，或该NDI信息预设为值“1”。可选地，该NDI信息的预设值是网络设备配置的。
若网络设备配置包括NDI信息的反馈方式，则终端设备在HARQ-ACK反馈过程中，需要反馈NDI信息，所以，该第二反馈序列中还包括NDI信息。该NDI信息可以为预设值，或可以根据实际需求进行设置。
可选地，若网络设备配置包括NDI信息的反馈方式，第二反馈序列中包括的NDI信息的个数是根据网络设备为该载波配置的最大TB个数来确定的。
可选地，若网络设备配置包括NDI信息的反馈方式，该第二反馈序列中不包括NDI信息。
例如，若该第二反馈序列包括用于指示释放SPS PDSCH的DCI对应的反馈信息，则该第二反馈序列中可以不包括NDI信息。
又例如，若该第二反馈序列包括配置半持续调度传输的载波上的反馈信息，譬如，包括SPS PDSCH资源上传输的SPS PDSCH对应的反馈信息，则该第二反馈序列中可以不包括NDI信息，即只要确定是SPS PDSCH资源上传输的SPS PDSCH，就可以默认所传输的数据为新数据。
可选地，若该N个载波中至少一个载波上被配置SPS PDSCH传输，该目标反馈序列包括该第一反馈序列和该第二反馈序列，该第二反馈序列包括被配置SPS PDSCH传输的至少一个载波上的反馈信息；或，若该N个载波中没有载波被配置SPS PDSCH传输，该目标反馈序列包括该第一反馈序列。
作为一种示例，若该N个载波中至少一个载波上被配置SPS PDSCH传输，则该目标反馈序列不仅包括第一反馈序列，还需要包括第二反馈序列，以通过该第二反馈序列来反馈配置SPS PDSCH传输的至少一个载波上的反馈信息。当然，若该N个载波中没有载波被配置SPS PDSCH传输，对于终端设备来说，可以确定该N个载波上的所有HARQ进程的HARQ进程号，在该种情况下，可以基于HARQ进程号对所有HARQ进程对应的反馈信息进行排序，即可以仅通过第一反馈序列就可以实现HARQ-ACK码本的反馈，所以，该目标反馈序列可以仅包括第一反馈序列。
可选地，该第二反馈序列的长度是根据该N个载波中配置SPS PDSCH传输的配置个数确定的。譬如，假设一个SPS PDSCH传输配置对应的反馈信息的信息比特数为1比特，若该N个载波中配置有一个SPS PDSCH传输，则可以确定第二反馈序列的长度为1比特；再如，若该N个载波中配置有3个SPS PDSCH传输，则该第二反馈序列的长度为3比特。
可选地，该第二反馈序列的长度是预设值。例如，该预设值为1，即不论根据该N个载波中配置的SPS PDSCH传输的个数为多少，第二反馈序列都包括1比特，该1比特用于对该1个或多个SPS PDSCH配置的释放进行反馈。
可选地，若该N个载波中至少一个载波上被配置SPS PDSCH传输，该目标反馈序列的长度是根据该第一反馈序列的长度和该第二反馈序列的长度确定的；或，若该N个载波中没有载波被配置SPS PDSCH传输，该目标反馈序列的长度是根据该第一反馈序列的长度确定的。
譬如，如果N个载波中的至少一个载波上被配置了J个SPS PDSCH传输，那么目标反馈序列的长度需要根据该第一反馈序列的长度和该第二反馈序列的长度来确定，例如，第一反馈序列长度为L比特，第二反馈序列长度为1比特，那么目标反馈序列长度为L+1比特。在某一次反馈的时候，有可能该J个SPS PDSCH传输都没有被激活，即该J个SPS PDSCH传输都不需要进行反馈，但是目标反馈序列的长度还是L+1比特，只是，此时该1比特对应的反馈全部为预设值或全部为NACK。
又譬如，如果N个载波中没有载波被配置SPS PDSCH传输，那么目标反馈序列的长度可以根据该第一反馈序列的长度来确定，例如，第一反馈序列长度为L比特，那么目标反馈序列长度也为L比特。
可选地，该目标反馈序列中还包括第一指示信息，其中，该第一指示信息用于确定该第一反馈序列中包括的信息比特总数；或，该第一指示信息用于确定该第二反馈序列中包括的信息比特总数；或，该第一指示信息用于确定该第一反馈序列和该第二反馈序列包括的信息比特总数。
作为一种示例，该目标反馈序列中可以包括第一指示信息，当该目标反馈序列中包括第一反馈序列时，该第一指示信息可以用于确定该第一反馈序列中共计包括多少个信息比特；或者，当该目标反馈序列中包括第二反馈序列时，该第一指示信息可以用于确定该第二反馈序列中共计包括个信息比特；或者，当目标反馈序列包括第一反馈序列和第二反馈序列，则该第一指示信息可以用于确定第二反馈序列共计包括多少个信息比特，或者，该第一指示信息用于确定第一反馈序列和第二反馈序列共计包括多少个信息比特。
可选地，该目标反馈序列的长度是根据该第一反馈序列的长度和/或该第二反馈序列的长度确定的。
由于该目标反馈序列可能包括第一反馈序列，也可能包括第二反馈序列，或者，还可能包括第一反馈序列和第二反馈序列，根据实际情况不同，该目标反馈序列的长度是根据该第一反馈序列的长度和/或该第二反馈序列的长度确定的。
步骤202：通过目标时间单元发送该目标反馈序列。
可选地，通过目标时间单元发送该目标反馈序列的实现可以包括：通过该目标时间单元发送第一反 馈序列，或者，通过该目标时间单元发送第二反馈序列，或者，通过该目标时间单元发送第一反馈序列和第二反馈序列。
相应地，接收设备在该目标时间单元上接收该目标反馈序列。
可选地，终端设备为下行传输确定目标反馈序列，并通过目标时间单元发送该目标反馈序列。相应地，网络设备在该目标时间单元上接收该目标反馈序列。
可选地，第一终端设备为侧行传输确定目标反馈序列，并通过目标时间单元发送该目标反馈序列。相应地，第二终端设备在该目标时间单元上接收该目标反馈序列。其中，侧行传输可以包括终端设备和终端设备之间的传输，例如V2X等。
可选地，网络设备为上行传输确定目标反馈序列，并通过目标时间单元发送该目标反馈序列。相应地，终端设备在该目标时间单元上接收该目标反馈序列。可选地，网络设备通过PDCCH或PDSCH发送该目标反馈序列，终端设备通过该PDCCH或该PDSCH接收该目标反馈序列。
可选地，该目标反馈序列包括该第一反馈序列和该第二反馈序列，该目标时间单元包括第一上行资源，在目标时间单元发送该目标反馈序列的具体实现可以包括：在该第一上行资源上发送该目标反馈序列，其中，该目标反馈序列中包括该第一反馈序列和该第二反馈序列，该目标反馈序列中的该第一反馈序列位于该第二反馈序列之前。可以理解的是，在这种方式中，第一反馈序列和第二反馈序列组成待反馈的HARQ-ACK码本。
譬如，该第一上行资源为PUCCH1。
也就是说，如果该目标反馈序列包括第一反馈序列和第二反馈序列，且在同一个上行资源上传输，则该第一反馈序列可以位于该第二反馈序列之前，譬如，目标反馈序列可以为{第一反馈序列，第二反馈序列}的形式。
作为另一种示例，该第一反馈序列也可以排在第二反馈序列的后面，譬如，该目标反馈序列可以为{第二反馈序列、第一反馈序列}。
相应地，该网络设备在第一上行资源上接收该目标反馈序列，譬如，该网络设备在PUCCH1上接收该目标反馈序列。
可选地，目标时间单元用于反馈第一反馈序列和第二反馈序列，该目标时间单元包括第一上行资源，在目标时间单元发送该目标反馈序列的具体实现可以包括：在该第一上行资源上发送该目标反馈序列，其中，该目标反馈序列中包括该第一反馈序列，或者说，在该第一上行资源上不发送该第二反馈序列。可以理解的是，在这种方式中，第一反馈序列组成待反馈的HARQ-ACK码本。也就是说，当期待在目标时间单元上反馈第一反馈序列和第二反馈序列时，可以认为第一反馈序列的优先级比第二反馈序列的优先级高，从而在目标时间单元上只反馈第一反馈序列，不反馈第二反馈序列。
可选地，若该目标反馈信息包括第一反馈序列、第二反馈序列和第一指示信息，且该第一指示信息用于确定该第二反馈序列中包括的信息比特总数，则该第一指示信息可以位于该第一反馈序列之前，或者，位于该第二反馈序列之前，譬如，可以为{第一指示信息、第一反馈序列、第二反馈序列}，或者为{第一反馈序列、第一指示信息、第二反馈序列}。
可选地，该目标反馈序列包括该第一反馈序列和该第二反馈序列，该目标时间单元包括第一上行资源和第二上行资源，在目标时间单元发送该目标反馈序列的具体实现可以包括：通过该第一上行资源发送该第一反馈序列，和/或，通过该第二上行资源发送该第二反馈序列。可以理解的是，在这种方式中，第一反馈序列组成第一上行资源上待反馈的HARQ-ACK码本，第二反馈序列组成第二上行资源上待反馈的HARQ-ACK码本。
譬如，该第一上行资源可以为PUCCH1，该第二上行资源可以为PUCCH2。
可选地，该第一上行资源和第二上行资源中至少一个为短上行资源，即PUCCH1和PUCCH2中至少一个PUCCH为短PUCCH。可选地，该第一上行资源和第二上行资源在时域上不重叠。
可选地，若该第一上行资源与该第二上行资源在时域上重叠，则可以按照一定的策略来传输该第一反馈序列和第二反馈序列，譬如可以优先发送第一上行资源上的第一反馈序列，然后发送第二上行资源上的第二反馈序列，或者从第一上行资源与第二上行资源中确定目标上行资源，并通过目标上行资源反馈包括第一反馈序列和第二反馈序列的HARQ-ACK码本等等，本申请实施例对此不做限定。
需要说明的是，在非授权场景中，在传输数据之前，通信设备需要做LBT(Listen Befor Talk，先听后说)监听，如果频谱当前被占用，则无法进行数据传输，所以，非授权场景中可能出现不能发送的情况，因此，在目标时间单元发送该目标反馈序列时，可能存在确定的目标反馈序列不能通过目标时间单元发送的情况，或者存在仅通过一个上行资源发送反馈序列的情况，即通过该第一上行资源发送该第一反馈序列，或者，通过该第二上行资源发送该第二反馈序列。
相应地，该网络设备在第一上行资源上接收该第一反馈序列，和/或，在第二上行资源上接收第二 反馈序列。
在本申请实施例中，确定目标反馈序列，该目标反馈序列包括第一反馈序列和第二反馈序列中的至少一个，该第一反馈序列包括N个载波上基于HARQ进程号排序的反馈信息，该第二反馈序列包括N个载波中的至少一个载波上的反馈信息，即目标反馈序列不仅可以包括基于HARQ进程号排序的反馈信息，还可以包括其他种情况对应的第二反馈序列，如此，可以提高HARQ-ACK码本反馈的灵活性。
可选地，在本申请实施例中，反馈信息可以包括以下情况中的至少一种：ACK或NACK，NDI，(Channel state information，信道状态信息)，SR(Scheduling request，调度请求)信息，RSRP(Reference signal received power，参考信号接收功率)信息，NFI(New feedback indicator，新反馈指示)等。
在一些实施例中，HARQ-ACK码本反馈可以是基于TB进行反馈的，也可以是基于CBG进行反馈，或者，还可以是基于TB和CBG进行反馈，针对这些情况，本申请实施例还提供了如下HARQ-ACK码本反馈方法：
步骤A1：确定目标反馈序列，该目标反馈序列包括第一反馈序列和第二反馈序列中的至少一种，该第一反馈序列包括N个载波上基于HARQ进程号排列的反馈信息，该第二反馈序列包括该N个载波中的至少一个载波上的反馈信息，该N为正整数。
通常情况下，如果一个TB包括多个CBG，由于在基于TB传输的过程中，如果一个TB中的至少一个CBG传输出错，则在使用HARQ对数据进行重新传输的过程中，需要对整个TB都进行重传，如此导致资源浪费。为此，目前提出了基于CBG的传输方式，例如，如果一个TB中的至少一个CBG传输出错，则在通过HARQ进程重传数据时，可以仅重新传输出错的至少一个CBG即可，不需要将整个TB都重新进行传输。由此不难理解，在基于CBG的数据重传中，可以对应有基于CBG的反馈方式。
在实施中，如果终端设备在某个载波上配置了基于CBG的传输方式，则终端设备在进行该载波的one-shot HARQ反馈时，如果该终端设备被配置了基于CBG的反馈方式，则需要进行基于CBG的反馈。在这种情况下，终端设备可以对该载波不进行基于TB的反馈，或者，终端设备也可以对该载波进行基于TB的反馈，本申请对此并不限定。或者，如果该终端设备没有被配置基于CBG的反馈方式，则需要进行基于TB的反馈。
可选地，在one-shot HARQ反馈中，网络设备可以通过RRC信令来配置终端设备在进行HARQ-ACK码本的反馈时是否要进行基于CBG的反馈。
作为示例，在one-shot HARQ反馈中，网络设备配置基于CBG的反馈方式包括：网络设备为一个PUCCH组或一个小区组配置基于CBG的反馈方式，或者，网络设备为每个载波独立配置基于CBG的反馈方式。
可选地，若网络设备配置基于CBG的反馈方式，且该N个载波中的M个载波被配置为基于CBG的传输方式，则该第一反馈序列包括的该M个载波上的至少一个HARQ进程中每个HARQ进程对应的反馈信息的长度是根据CBG的反馈长度确定的，且该第一反馈序列包括的K个载波上的至少一个HARQ进程中每个HARQ进程对应的反馈信息的长度是根据TB的反馈长度确定的，该K个载波包括该N个载波中除该M个载波之外的其他载波，该M、该K均为小于或等于N的整数。
作为一种示例，若网络设备配置基于CBG的反馈方式，如果存在M个载波被配置为基于CBG的传输方式，那么，这M个载波上的至少一个HARQ进程中每个HARQ进程对应的反馈信息可以是基于CBG进行反馈的，即该M个载波上的至少一个HARQ进程中每个HARQ进程对应的反馈信息的长度是根据CBG的反馈长度确定的。具体地，该M个载波中的每个载波对应的CBG的反馈长度是根据网络设备为该载波配置的每个TB包括的最大CBG个数确定的，例如，可以通过maxCodeBlockGroupsPerTransportBlock这个参数指示该最大CBG个数。该M个载波中的不同载波上对应的CBG的反馈长度可以不同，也可以相同，本申请对此并不限定。而该N个载波中除了该M个之外的其他K个载波上的至少一个HARQ进程中每个HARQ进程对应的反馈信息可以是基于TB进行反馈，即K个载波上的至少一个HARQ进程中每个HARQ进程对应的反馈信息的长度是根据TB的反馈长度确定的。具体地，该K个载波中的每个载波对应的TB的反馈长度是根据网络设备为该载波配置的最大TB个数确定的，例如，可以通过maxNrofCodeWordsScheduledByDCI这个参数来指示该最大TB个数。该K个载波中的不同载波上对应的TB的反馈长度可以不同，也可以相同，本申请对此并不限定。
可选地，在本申请中，一个载波对应的CBG的反馈长度是根据网络设备为该载波配置的每个TB包括的最大CBG个数来确定的。例如，可以通过该载波上的maxCodeBlockGroupsPerTransportBlock这个参数指示该最大CBG个数。
可选地，在本申请中，一个载波对应的TB的反馈长度是根据网络设备为该载波配置的最大TB个数来确定的。例如，可以通过该载波上的maxNrofCodeWordsScheduledByDCI这个参数指示该最大TB 个数。例如，如果该载波配置的最大TB个数为1，则该载波对应的TB的反馈长度为1；或者，如果该载波配置的最大TB个数为2，则该载波对应的TB的反馈长度为2；或者，如果该载波配置的最大TB个数为2，且该载波被配置空分复用绑定反馈，则该载波对应的TB的反馈长度为1。
可选地，在本申请中，如果网络设备配置了包括NDI信息的反馈，那么一个HARQ进程对应的NDI信息的比特个数是根据网络设备为该载波配置的最大TB个数来确定的。或者说，无论是否被配置空分复用绑定反馈，每个TB的NDI信息都是独立反馈的。
可选地，第一反馈序列还可以包括该M个载波上的至少一个HARQ进程对应的基于TB的反馈信息。
可选地，如果该N个载波中没有载波被配置基于CBG的传输方式，和/或，没有被配置基于CBG的反馈方式，则第一反馈序列包括N个载波上的所有HARQ进程对应基于TB的反馈信息，即第一反馈序列包括的N个载波上的至少一个HARQ进程中每个HARQ进程对应的反馈信息的长度是根据TB的反馈长度确定的。例如，该N个载波中的每个载波对应的TB的反馈长度是根据网络设备为该载波配置的最大TB个数参数确定的。
可选地，若网络设备配置基于CBG的反馈方式，且该N个载波中的目标载波被配置为基于CBG的传输方式，如果在该目标载波上接收到调度，则该第一反馈序列包括的该目标载波上的至少一个HARQ进程中的每个HARQ进程对应的反馈信息的长度是根据CBG的反馈长度确定的；和/或，如果在该目标载波上没有接收到调度，则该第一反馈序列包括的该目标载波上的至少一个HARQ进程中的每个HARQ进程对应的反馈信息的长度是根据TB的反馈长度确定的。
也就是说，如果该N个载波中存在被配置基于CBG的传输方式的目标载波，则可以确定在该目标载波载波上是否接收到调度，如果接收到调度，则该目标载波上的至少一个HARQ进程中的每个HARQ进程对应的反馈信息是基于CBG进行反馈的。如果没有被调度，则即便是被配置了基于CBG的传输方式，该目标载波上的至少一个HARQ进程对应的反馈信息还是基于TB进行反馈的。即，在被配置了基于CBG的传输方式的情况下，只有被调度了，才会基于CBG进行反馈，如果没有被调度，就基于TB进行反馈。
需要说明的是，上述所说的基于TB进行反馈是指针对每个TB对应有一个反馈信息；基于CBG进行反馈是指针对每个CBG都有一个反馈信息。
作为一种示例，在该目标载波上接收到的调度包括以下至少一种：
(1)调度的PDSCH传输。
(2)用于激活下行SPS PDSCH的PDCCH传输。
(3)用于释放下行SPS PDSCH的PDCCH传输。
(4)无对应PDCCH调度的下行SPS PDSCH传输。
可选地，该第一反馈序列包括N个载波上所有HARQ进程基于HARQ进程号排序的反馈信息，该第一反馈序列的排列顺序依次为CBG和/或TB、HARQ进程号、载波。
譬如，如果第一反馈序列包括两个载波上的所有HARQ进程对应的反馈信息，其中第一个载波上包括16个HARQ进程，第二个载波上包括8个HARQ进程，则在该第一反馈序列对应的码本中，先排列第一个载波中的16个HARQ进程中每个HARQ进程对应的基于CBG和/或TB的反馈信息，之后，再排列第二个载波中的8个HARQ进程中每个HARQ进程对应的基于CBG和/或TB的反馈信息。
假设第一反馈序列包括两个载波上的所有HARQ进程对应的反馈信息，其中载波0上包括16个HARQ进程，且载波0被配置为基于CBG的传输方式，载波1上包括8个HARQ进程，且载波1没有被配置为基于CBG的传输方式。
作为一种示例，若网络设备没有配置基于CBG的反馈方式，第一反馈序列包括载波0和载波1上的所有HARQ进程对应的基于TB的反馈信息，且第一反馈序列中的反馈信息的排序方式包括：先为载波0中的16个HARQ进程中每个HARQ进程对应的基于TB的反馈信息，再为载波1中的8个HARQ进程中每个HARQ进程对应的基于TB的反馈信息。
作为一种示例，若网络设备配置了基于CBG的反馈方式，第一反馈序列包括载波0和载波1上的所有HARQ进程对应的反馈信息，且第一反馈序列中的反馈信息的排序方式包括：先为载波0中的16个HARQ进程中每个HARQ进程对应的基于CBG的反馈信息，再为载波1中的8个HARQ进程中每个HARQ进程对应的基于TB的反馈信息。
作为一种示例，若网络设备配置了基于CBG的反馈方式，第一反馈序列包括载波0和载波1上的所有HARQ进程对应的反馈信息，且第一反馈序列中的反馈信息的排序方式包括：先为载波0中的16个HARQ进程中每个HARQ进程对应的基于CBG和TB的反馈信息，再为载波1中的8个HARQ进程中每个HARQ进程对应的基于TB的反馈信息。
作为一种示例，若网络设备配置了基于CBG的反馈方式，第一反馈序列包括载波0和载波1上的所有HARQ进程对应的基于CBG的反馈信息，且第一反馈序列中的反馈信息的排序方式包括：先为载波0中的16个HARQ进程中每个HARQ进程对应的基于CBG的反馈信息，再为载波1中的8个HARQ进程中每个HARQ进程对应的基于CBG的反馈信息。
可选地，若网络设备配置基于CBG的反馈方式，该第二反馈序列包括至少一个载波上的第一反馈信息，则该第一反馈信息的长度是根据CBG的反馈长度确定的；或，该第一反馈信息的长度是根据TB的反馈长度确定的；或，该第一反馈信息的长度是根据预设值确定的。
作为一种示例，CBG的反馈长度可以为高层参数配置的一个TB对应的CBG的反馈比特数。
作为一种示例，TB的反馈长度可以是高层参数配置的TB的反馈比特数。
作为一种示例，该预设值可以是标准预设的或高层参数配置的，譬如，该预设值可以为1比特。
示例性的，假设该第二反馈序列包括至少一个载波上的第一反馈信息，该载波上每个HARQ进程中对应的最大TB个数为2，每个TB包括的最大CBG个数为4。则在一种实现方式中，该第一反馈信息的长度可以根据4来确定。在另一种实现方式中，该第一反馈信息的长度可以根据2来确定。在另一种实现方式中，该第一反馈信息的长度基于预设值确定，其中，该预设值可以是标准预设的或网络设备通过高层参数配置的，例如，通过RRC参数配置。
譬如，假设该至少一个载波上配置有y个SPS PDSCH传输，该第一反馈信息包括该至少一个载波上配置的y个SPS PDSCH传输中的至少一个SPS PDSCH传输的去激活DCI(或者说去激活命令)对应的反馈信息，该第一反馈信息可以根据预设值来确定，例如，该预设值可以为1比特，或者说该y个配置的SPS PDSCH传输的去激活命令对应1比特；或者，假设每个SPS PDSCH的去激活DCI对应1比特反馈信息，该至少一个载波上包括y个配置，则该第一反馈信息的长度为1*y，即y比特。
可选地，若第二反馈序列中只包括该N个载波中的至少一个载波上配置的至少一个SPS PDSCH传输的去激活DCI(或者说去激活命令)对应的反馈信息，则第二反馈序列的长度为1比特。
可选地，该第二反馈序列的长度是根据该N个载波中配置SPS PDSCH传输的配置个数确定的。
比如，假设一个SPS PDSCH配置对应的反馈长度为1比特，该N个载波中有s个SPS PDSCH配置，那么，该第二反馈序列的长度根据s确定。
步骤A2：通过目标时间单元发送该目标反馈序列。
该步骤的具体实现可以参见上述图2所示实施例中的步骤202，这里不再重复赘述。
需要说明的是，图2所示实施例中的方案同样可以应用于该实施例中，即该实施例中除了上述记载内容外，还可以包括图2所示实施例中的部分或者全部内容。
在本申请实施例中，确定目标反馈序列，该目标反馈序列包括第一反馈序列和第二反馈序列中的至少一个，该第一反馈序列包括N个载波上基于HARQ进程号排序的反馈信息，该第二反馈序列包括N个载波中的至少一个载波上的反馈信息，即目标反馈序列不仅可以包括基于HARQ进程号排序的反馈信息，还可以包括其他种情况对应的第二反馈序列，如此，可以提高HARQ-ACK码本反馈的灵活性。
为了便于理解，接下来通过如下几个示例来对上述提供HARQ-ACK码本的反馈方法的具体实现来进行简单举例。
示例一：第二反馈序列包括用于释放下行SPS PDSCH的第一DCI对应的反馈信息。
在一种可能的实现方式中，当终端设备需要在slot n上反馈基于HARQ进程号排列的第一反馈序列时，如果终端设备在该slot n上也需要反馈第一DCI对应的反馈信息，则可以生成第二反馈序列，该第二反馈序列中包括第一DCI对应的反馈信息。
终端设备可以将第二反馈序列附在第一反馈序列之后，得到目标反馈序列。
作为一种示例，如果网络设备配置了包括NDI反馈信息的反馈方式，则该第二反馈序列中可以不包括NDI信息，或者，该第二反馈序列中包括NDI信息，该NDI信息可以为预设值，例如，该NDI信息预设为值“0”，或该NDI信息预设为值“1”。
可选地，若网络设备配置基于CBG的反馈方式，如果该第一DCI对应的载波被配置了CBG的传输方式，则该第二反馈序列的长度可以是基于CBG的反馈长度来确定的，或者，该第二反馈序列的长度是基于TB的反馈长度来确定的，或者，该第二反馈序列的长度是根据预设值确定的，其中，CBG的反馈长度可以是高层参数配置的一个TB对应的CGB的反馈比特数，TB的反馈长度可以是根据高层参数配置的最大TB个数确定的反馈比特数。
终端设备通过PUCCH1发送目标反馈序列，该目标反馈序列包括该第一反馈序列和该第二反馈序列。
在一种可能的实现方式中，当终端设备被指示在slot n上反馈基于HARQ进程号排列的第一反馈序 列时，如果终端设备在该slot n上也被指示反馈第一DCI对应的反馈信息，则终端设备可以不在该slot n上反馈第一DCI对应的反馈信息。也就是说，当终端设备被指示在slot n上反馈Type-3 HARQ-ACK码本和反馈SPS PDSCH释放对应的反馈信息时，终端设备可以认为Type-3 HARQ-ACK码本的优先级高于SPS PDSCH释放对应的反馈信息的优先级，从而，该终端设备在slot n上只反馈Type-3 HARQ-ACK码本。
终端设备通过PUCCH1发送目标反馈序列，该目标反馈序列包括该第一反馈序列。
示例二：第二反馈序列包括无DCI调度的SPS PDSCH对应的反馈信息。
当终端设备需要在slot n上反馈基于HARQ进程号排列的第一反馈序列时，如果终端设备在该slot n上也需要反馈无DCI调度的下行SPS PDSCH对应的反馈信息，则可以生成第二反馈序列，该第二反馈序列包括无DCI调度的下行SPS PDSCH对应的反馈信息。
终端设备可以将第二反馈序列附着在第一反馈序列之后，得到目标反馈序列。
进一步地，如果网络设备配置了包括NDI信息的反馈方式，则该第二反馈序列中还包括NDI信息，该NDI信息可以为预设值，该NDI信息预设为值“0”，或该NDI信息预设为值“1”。或者，该第二反馈序列中不包括NDI信息。
对于网络设备来说，如果检测到该目标反馈序列中包括该第二反馈序列，可以确定下行SPS PDSCH对应的PDSCH为新传，作为一种示例，网络设备可以不需要读取终端设备反馈的NDI信息。
如果无DCI调度的下行SPS PDSCH对应的载波被配置了CBG的反馈方式，则第二反馈序列中的反馈信息可以是基于CBG进行反馈的，即该第二反馈序列的反馈长度可以是根据CBG的反馈长度来确定的。或者，该第二反馈序列中的反馈信息是基于TB进行反馈的，即该第二反馈序列的反馈长度是根据TB的反馈长度来确定的。其中，CBG的反馈长度可以为高层参数配置的一个TB对应的CBG的反馈比特数，TB的反馈长度可以是根据高层参数配置的最大TB个数确定的反馈比特数。
终端设备通过PUCCH1发送目标反馈序列，该目标反馈序列包括该第一反馈序列和该第二反馈序列。
示例三：如果第一载波被配置了基于CBG的传输方式，且该网络设备配置基于CBG的反馈方式，则本申请提供的方式可以包括：
当终端设备需要在slot n上反馈基于HARQ进程号排序的第一反馈序列时，该第一反馈序列中包括第一载波上基于HARQ进程号排序的反馈信息，如果终端设备在该第一载波上被调度，则第一反馈序列包括的第一载波上的至少一个HARQ进程中的每个HARQ进程对应的反馈信息的长度是根据CBG的反馈长度确定的。如果终端设备在载波上没有收到调度，则第一反馈序列包括的第一载波上的至少一个HARQ进程中的每个HARQ进程对应的反馈信息的长度是根据TB的反馈长度确定的。
终端设备通过PUCCH1发送目标反馈序列，该目标反馈序列包括该第一反馈序列。
示例四：假设终端设备被配置了两个载波，分别为CC1和CC2，其中，载波1上被配置了基于CBG的传输方式。假设终端设备被配置了One shot HARQ-ACK码本反馈，且被配置了基于CBG的反馈方式。
请参考图3，在载波1上，终端设备在时隙n上收到调度的PDSCH1且对应HARQ进程号为4且PDSCH1包括4个CBG，在时隙n+1上收到调度的PDSCH3且对应HARQ进程号为8且PDSCH3包括2个CBG，在时隙n+2上收到用于释放SPS PDSCH调度的第一DCI。
在载波2上，终端设备在时隙n上收到没有PDCCH调度的SPS PDSCH即PDSCH2且对应HARQ进程号为1，在时隙n+2上收到DCI调度的PDSCH4且对应HARQ进程号为9，且时隙n+2上的DCI同时触发在时隙n+3上进行one-shot HARQ反馈。
如此，终端设备生成目标反馈序列，该目标反馈序列包括第一反馈序列和第二反馈序列，其中，第一反馈序列包括载波1和载波2上的基于HARQ进程号排序的反馈信息，第二反馈序列包括载波1上的第一DCI对应的反馈信息。
假设每个载波上的HARQ进程数为16，每个HARQ进程中包括的最大TB个数为1，载波1上每个TB对应的CBG反馈比特数为4。未被调度的HARQ进程对应的反馈信息为NACK，和/或，未被调度的HARQ进程对应的NDI信息为0。应理解，未被调度的CBG对应的反馈信息也应为NACK。
作为一种示例，目标反馈序列的码本可以如图4所示，其中，第一反馈序列包括两个载波上的所有HARQ进程对应的反馈信息，其中，载波1上调度的PDSCH对应的反馈信息均采用基于CBG的传输方式进行反馈，第二反馈序列包括载波1上的第一DCI对应的1比特的反馈信息。

作为一种示例，如果第一载波没有被配置基于CBG的传输方式，和/或，网络设备没有配置基于CBG的反馈方式，则第一反馈子序列中包括的第一载波上的至少一个HARQ进程中每个HARQ进程对应的反馈信息的长度是基于TB的反馈长度确定的。例如，该TB的反馈长度是根据网络设备为该载波配置的最大TB个数参数确定的。
作为一种示例，如果第一载波被配置了基于CBG的传输方式，且网络设备配置了基于CBG的反馈方式，则第一反馈子序列中包括该第一载波上至少一个HARQ进程中每个HARQ进程对应的反馈信息的长度是基于CBG的反馈长度来确定的。
