HARQ-ACK反馈码本的发送方法、装置及设备
本申请要求于2017年10月9日提交中国专利局、申请号为201710930785.6、申请名称为“HARQ-ACK反馈码本的发送方法、装置及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种HARQ-ACK反馈码本的发送方法、装置及设备。
背景技术
长期演进(Long Term Evolution，LTE)系统中下行物理层数据由物理下行共享信道(Physical Downlink Shared Channel，PDSCH)承载。为了确保物理层数据传输的可靠性和传输效率，LTE采用了混合自动重传请求(Hybrid Automatic Repeat ReQuest，HARQ)。即发送的数据在物理层可以对应为传输块(Transmit Block，TB)，网络设备为TB加上循环冗余校验(Cyclic Redundancy Check,CRC)用于终端校验该TB是否成功接收。进一步地，还可以将TB分为若干个码块(Code Block,CB)，网络设备可以针对每个CB分别加上对应的CRC用于校验每个CB各自是否成功接收。终端接收到数据后，尝试对接收到的数据进行译码，若所有CB的CRC都校验成功，且TB的CRC校验成功，则反馈1比特位的TB级的确认应答(acknowledgement,ACK)给网络设备，以指示数据接收成功；若存在某个CB的CRC校验失败或该TB的CRC校验失败，则反馈1比特位的TB级的否认应答(negative acknowledgement,NACK)给网络设备，以指示数据接收失败。此时，网络设备需要重传整个TB。其中，ACK或者NACK均被称为HARQ-ACK信息。
现有技术支持终端将网络设备传输的多个TB的译码结果在一个上行HARQ-ACK信息(Uplink Control Information，UCI)上传输，该多个TB可以来自不同的下行时间单元和/或多输入多输出(Multiple-Input Multiple-Output，MIMO)下的不同码字和/或载波聚合下的不同载波。这种方式称为HARQ-ACK复用(HARQ-ACK multiplexing)，该UCI中包含HARQ-ACK反馈码本，HARQ-ACK反馈码本的大小为该码本包括的HARQ-ACK信息的比特数；将HARQ-ACK反馈码本各比特对应哪个TB为码本的索引方式。
在只有个别CB接收失败的场景下，仍然需要重传整个TB，会导致通信效率较低的问题，因此，随着通信技术的发展，可以通过信令配置码块组(Code Block Group，CBG)级传输和CBG级反馈，具体的将TB划分后的CB分组成至少1个CBG，每个CBG至少包含1个CB，为每个CBG反馈1比特的HARQ-ACK，即当某个CBG包含的CB的CRC都校验通过或者译码正确，则为该CBG反馈1比特的ACK，否则为该CBG反馈1比特的 NACK，如此网络设备在收到各CBG的HARQ-ACK信息后，只需重传NACK的CBG，从而提高了重传效率，不过相比于1比特的TB级反馈，CBG级的反馈开销增大了。为了灵活控制反馈开销和保证上行覆盖性能，在网络设备利用无线资源控制(radio resource control，RRC)信令为终端设备配置了CBG传输和反馈后，仍可以通过下行控制信令(Downlink control information，DCI)来通知终端灵活回退到TB级传输和TB级反馈。
然而，目前基于TB级传输和TB级反馈的DCI均是针对一个TB，或者是针对MIMO中的两个码字进行的，在HARQ-ACK multiplexing下，在HARQ-ACK multiplexing场景下，如何进行HARQ-ACK反馈码本的传输是本申请亟待解决的技术问题。
发明内容
本申请提供一种HARQ-ACK反馈码本的发送方法、装置及设备。即本申请提供了在HARQ-ACK multiplexing场景下，如何进行HARQ-ACK反馈码本的传输的方案。
第一方面，本申请提供一种HARQ-ACK反馈码本的发送方法，包括：终端在至少一个载波的多个时间单元上检测下行控制信息DCI，DCI的类型为第一DCI类型或者第二DCI类型，第一DCI用于指示对第一DCI调度的数据反馈码块组CBG级的混合自动重传请求-确认回答HARQ-ACK信息，第二DCI用于指示对第二DCI调度的数据反馈传输块TB级的HARQ-ACK信息；终端向网络设备发送HARQ-ACK反馈码本，HARQ-ACK反馈码本包括DCI调度的至少一个数据的HARQ-ACK信息；其中，HARQ-ACK反馈码本由DCI类型和HARQ-ACK反馈码本的类型确定；HARQ-ACK反馈码本的类型为半静态类型或者动态类型。
本申请的有益效果为：通过该方法可以解决在HARQ-ACK multiplexing场景下，如何进行HARQ-ACK反馈码本的传输的技术问题。
可选地，若第一数据基于第一DCI调度，则HARQ-ACK反馈码本中第一数据对应的N1比特中前M1比特为第一数据包括的码块组CBG级的HARQ-ACK信息；N1比特中后N1-M1比特为否定回答NACK；N1为网络设备为第一数据配置的最大CBG个数，M1为第一数据实际包括的CBG个数；若第二数据基于第二DCI调度，HARQ-ACK反馈码本中第二数据对应的N2比特中前1比特为第二数据的TB级的HARQ-ACK信息；N2比特中后N2-1比特中每一比特为NACK或者每一比特为TB级的HARQ-ACK信息；N2为网络设备为第二数据配置的最大CBG个数；其中，第一数据为至少一个数据中基于第一DCI调度的任一个数据，第二数据为至少一个数据中基于第二DCI调度的任一个数据。
本申请的有益效果为：由于当第二数据基于第二DCI调度时，HARQ-ACK反馈码本中第二数据对应的N2比特中前1比特为第二数据的TB级的HARQ-ACK信息，即总的码本大小不变，从而有助于网络设备解码UCI，进而提高上行UCI的覆盖/解码性能。此外，由于总的码本大小不变，各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。
可选地，HARQ-ACK反馈码本中包括的所有HARQ-ACK信息均为CBG级的HARQ-ACK信息。
本申请的有益效果为：由于总的码本大小不变，从而有助于网络设备解码UCI，进而 提高上行UCI的覆盖/解码性能。此外，由于总的码本大小不变，各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。
可选地，还包括：终端确定HARQ-ACK反馈码本的大小；若确定的HARQ-ACK反馈码本的大小小于预设阈值，则HARQ-ACK反馈码本中第二数据对应的N2比特中前1比特为第二数据的TB级的HARQ-ACK信息；N2比特中后N2-1比特中每一比特为NACK或者每一比特为TB级的HARQ-ACK信息；若确定的HARQ-ACK反馈码本的大小大于或者等于预设阈值，HARQ-ACK反馈码本中第二数据对应的N2比特中前M2比特为第二数据的CBG级的HARQ-ACK信息；N2比特中后N2-M2比特为否定回答NACK；N2为网络设备为第二数据配置的最大CBG个数；M2为第二数据实际包括的CBG个数；其中，第二数据为至少一个数据中基于第二DCI调度的任一个数据。
本申请的有益效果为：由于总的码本大小不变，从而有助于网络设备解码UCI，进而提高上行UCI的覆盖/解码性能。此外，由于总的码本大小不变，各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。
可选地，若HARQ-ACK反馈码本的类型为动态类型，则HARQ-ACK反馈码本包括第一子码本和/或第二子码本；其中，第一子码本包括基于第一DCI调度的数据的CBG级的HARQ-ACK信息，第二子码本包括基于第二DCI调度的数据的TB级的HARQ-ACK信息。

本申请的有益效果为：通过上述第一子码本和第二子码本的排布，一方面由于第二子码本中每个第二数据对应的HARQ-ACK信息均占用1比特，而无需占用N比特，从而可以降低HARQ-ACK反馈码本的开销。另一方面将第一DCI的DAI和第二DCI的DAI分开计数，各自产生第一子码本和第二子码本，第一子码本和第二子码本分开排布，从而可以防止当存在DCI丢失的情况时，由于第一子码本占用比特数不变，各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。进一步的，在第二子码本中各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。
可选，第一子码本大小至少基于第一DCI中的下行分配索引DAI值和N1确定；第二子码本大小至少基于第二DCI中的DAI值确定。

具体实施方式
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(也被称为HARQ-ACK反馈码本)：终端可以将网络设备传输的多个数据的译码结果在一个UCI中反馈给网络设备，所述多个数据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。该UCI中包含的译码结果即为HARQ反馈码本。例如：多个数据可以来自不同的下行时间单元和/或MIMO下的不同码字表示多个数据可以是不同下行时间单元的数据，或者是MIMO下的不同码字，又或者是部分数据是不同下行时间单元的数据，其他部分数据是MIMO下的不同码字。
本申请中的数据可以理解为TB，或者是码块组(code block group，CBG)，或者是其他的数据，本申请对此不做限制。
在本申请中，时间单元可以为子帧、传输时间间隔(其中一个传输时间间隔等于若干个子帧长度和，或者若干个传输时间间隔之和等于一个子帧长)，也可以是1个时域符号、多个时域符号、1个时隙(slot)、多个时隙、1个迷你时隙(mini-slot)、多个迷你时隙，或者迷你时隙和时隙的组合，或者符号和时隙的组合、mini时隙和时隙的组合等，各时间单元的符号数/长度也不限制必须相同。若1个时间单元承载PDSCH或PDCCH或UCI等，PDSCH或PDCCH或UCI可以不需要完全占满该时间单元的所有时域符号，和/或，频域资源。
本申请中物理下行控制信道(Physical Downlink Control Channel，PDCCH)(用于传输DCI)和PDSCH承载在下行时间单元上(或者混合上下行时间单元中的下行传输机会上)，而UCI承载在上行时间单元上(或者混合上下行时间单元中的上行传输机会上)。1个UCI或者上行时间单元或者混合上下行时间单元中的上行传输机会上可能需要反馈1个或多个下行时间单元传输的数据的HARQ-ACK信息，将反馈的下行时间单元集合称为上述的HARQ复用窗口。HARQ复用窗口还可以称为时间窗，或者是绑定窗，或者是关联集合(Associated Sets)等。具体地，图1为本申请一实施例提供的HARQ复用窗口示意图，如图1所示，针对目标上行时间单元(承载UCI的上行时间单元)，其对应的HARQ复用窗口包括5个时间单元，即该5个时间单元上传输的数据的HARQ-ACK信息可以在目标上行时间单元上传输或者UCI上承载。综上可知，每个上行时间单元可能需要反馈1个或多个下行时间单元传输的HARQ-ACK信息。本申请中时间窗可以有下面2种定义：
1、时间窗为承载PDSCH的下行时间单元集合，所述PDSCH的译码结果HARQ-ACK可以在同1个UCI上承载。该情况下，时间窗的确定可以与K1相关，例如对于时间单元n上的目标UCI，其对应的时间窗内可能的最早或者最前时间单元为n-“K1的最大值”，其对应的时间窗内可能最晚或者最后的时间单元为n-“K1的最小值”。例如对于上行时间单元n，假设K1最小值为2，K1最大值为6，则其对应的时间窗最早开始的时间单元为n-6，时间窗最后的一个时间单元可以为n-2。其中，K1为传输PDSCH的时间单元与PUCCH或者物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的时间单元之间的时间关系，所述PUCCH或者PUSCH用于传输所述数据的HARQ-ACK信息/UCI。具体的，若在第n个时间单元上通过PDSCH发送下行数据，对应的通过物理上行共享信道PUSCH或者PUCCH传输确认信息使用的时间单元为第n+K1个时间单元。
2、时间窗为承载PDCCH的下行时间单元集合，所述PDCCH调度的PDSCH的译码结果HARQ-ACK可以在同1个目标上行UCI上承载。该情况下，时间窗的确定可以与K1和K0相关，例如对于时间单元n上的目标UCI，其对应的时间窗内可能的最早或者最前时间单元为n-“K1的最大值”-“K0的最大值”，其对应的时间窗内可能最晚或者最后的时间单元为n-“K1的最小值”-“K0的最小值”。例如对于上行时间单元n，假设K1最小值为2，K1最大值为6，K0最小值为0，K0最大值为4，则其对应的时间窗最早开始的时间单元为n-6-4，时间窗最后的一个时间单元可以为n-2。其中，K0可以为传输PDCCH的时间单元与传输物理下行共享信道PDSCH的时间单元之间的时间关系。具体的，若在第n个时间单元上通过PDCCH发送调度信息，对应的PDSCH使用的时间单元为第n+K0个时间单元。
在LTE中的时间窗是固定的，即根据TDD上下行时间单元配比确定，而NR系统中时间窗可以是动态且可配置的，具体的上述K1和K0是通过RRC信令半静态配置一个K1和/或K0的可能取值集合，然后DCI信令通知K1和/或K0的具体取值信息。本申请对时间窗的配置/确定方式不做限定。
HARQ-ACK multiplexing：终端将网络设备传输的多个TB的译码结果在一个UCI上传输，该多个TB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。这种方式称为HARQ-ACK multiplexing。HARQ-ACK multiplexing下的码本生成方式可以为半静态码本或者动态码本。
半静态HARQ-ACK反馈码本大小由3个维度确定：1、载波数，载波数可以是网络设备通过信息配置的(该信息比如是RRC，媒体接入控制控制元素(Media Access Control Control Element,MAC CE)，系统信息块(system information block,SIB)等中的一种或多种组合，本申请不做限定)；2、各载波上需要反馈的时域集合(即上述的HARQ复用窗口)中的时间单元个数LTE中所述时域集合取决于下行链路(Downlink，DL)/上行链路(Uplink，UL)配比(NR中可能会调整，比如根据RRC配置的HARQ反馈的时域集合大小确定，或者根据RRC配置的反馈时序可能的取值集合确定等，本申请不做限定)；3、码字数，若某个载波上的HARQ复用窗口内存在至少1个2码字传输且不采用混合自动重传请求-确认回答捆绑(HARQ-ACK bundling)方式，则半静态码本下该载波对应的反馈比特数为该载波的所述HARQ复用窗口大小乘以2。其中“/”表示或的意思。
具体地，网络设备为终端配置了L个载波可以用来数据传输，L个载波的编号从0到L-1。作为一种实现方式，半静态码本为将L个载波上数据的HARQ-ACK信息依次排列后的结果。以C＝5为例进行说明，载波0为主载波(Primary Cell，Pcell)，其它4个载波为辅载波(Secondary Cell，Scell)，确定在Pcell上需要发送的HARQ-ACK反馈码本：确定在Scell上需要发送的HARQ-ACK反馈码本：将在Pcell和Scell需要发送的HARQ-ACK反馈码本级联成最终的HARQ-ACK反馈码本。图2为本申请一实施例提供的TDD配比示意图，如图2所示，5个载波都是LTE中的TDD配比1的载波，在时间单元7上，需要对时间单元0和时间单元1进行HARQ反馈，终端只在Pcell的时间单元0上正确接收数据，在其它辅载波上未正确接收数据或者无数据传输，则HARQ-ACK反馈码本为1000000000(前两位10为Pcell上的HARQ-ACK信息，后8个比特对应4个Scell上的HARQ-ACK信息)。
此外，当网络设备通过RRC信令为终端设备在某个载波上配置了CBG级传输和CBG反馈，且配置最大CBG个数为N时，半静态码本中该载波的HARQ-ACK信息比特数需要在上面得到的大小基础上乘以N。各TB对应位置的N比特中前M比特对应该TB的各CBG的HARQ-ACK信息，后N-M可以为默认的NACK。
可选地，关于最大CBG个数N的配置有下面几种方式。方式1、该配置最大CBG个数N可以是网络设备为所有载波共同配置的一个值，即网络设备只需1条信令配置1个参数N；方式2、网络设备为每个载波配置一个值(比如为第c个载波配置最大CBG个数为Nc，即网络设备需要C条信令配置C个参数)，在2个码字情况下，第c个载波的2个码字对应的Nc相等；方式3、网络设备为每个码字配置一个值，且所有载波的相同码字共同配置一个值，即所有载波的第一个码字的采用N1，所有载波的第二个码字采用N2；方式4、网络设备为每个载波的每个码字配置一个值；方式5、网络设备为每个载波各配置一个值(比如为第c个载波配置Nc，即需要C条信令、配置C个参数),在2个码字情况下，第c个载波的2个码字的最大CBG之和为Nc；方式6、网络设备为所有载波配置一个值N,在2个码字情况下，2个码字的最大CBG之和为N。以上任意方式对本申请都适用，为了便于描述本申请采用方式2进行描述。
为了便于描述，本申请以1个载波1个码字传输为例，本申请提供的方案对于多载波多个码字的情况同样适用，可以类似得到，本申请对此不再赘述。
动态HARQ-ACK反馈码本：对于只配置1个载波的情况，各DCI中存在1个下行分 配索引DAI(Downlink Assignment Index，DAI)，该DAI也可以称为计数器型下行分配索引(Counter Downlink Assignment index，C-DAI)。
终端根据HARQ复用窗口内检测到的DCI确定码本大小(具体地，作为一种实现方式，终端根据最后一个检测到的DCI的DAI值确定码本大小)，将TB的HARQ-ACK信息编排到调度该TB的DCI中DAI值对应的位置。
图3为本申请一实施例提供的数据传输示意图，如图3所示，该HARQ复用窗口为5个时间单元，假设该载波RRC信令关闭了CBG级反馈(即统一采用LTE中的TB级反馈)，且码字数为1，其中终端未检测到第3个时间单元调度的DCI，基于此，确定HARQ-ACK反馈码本大小为4比特(因为最后一个检测到的DAI值为4)，第1比特为TB1的HARQ-ACK信息(DAI＝1)，第2比特为TB2的HARQ-ACK信息(DAI＝2)，第4比特为TB4的HARQ-ACK(DAI＝4)，然后将第3比特设置为NACK(由于该DCI丢失，终端没有检测成功)。其中，每个时间单元左上角的小框表示调度相应数据传输的DCI。需要说明的是：调度数据(PDSCH)传输的DCI(PDCCH)可以在一个时间单元上，也可以不在一个时间单元上。
对于配置大于1个载波的情况，各DCI中存在两个DAI(一个是C-DAI，另一个是总数型下行分配索引(Total Downlink Assignment Index，T-DAI)，其中，1个时间单元上的所有载波的T-DAI相等。终端根据HARQ复用窗口内检测到的DCI确定码本大小(一种可能的方式，根据最后一个检测到的DCI的DAI值)，将TB的HARQ-ACK信息编排到调度该TB的DCI中DAI值对应的位置。图4为本申请另一实施例提供的数据传输示意图，如图4所示，配置了5个载波，HARQ复用窗口为4个时间单元，空白格表示没有PDSCH传输，剩下的花纹格表示有PDSCH传输，在HARQ复用窗口的第1个时间单元只有载波1有数据调度，则total DAI＝1，counter DAI＝1。在，HARQ复用窗口的第2个时间单元，载波0和载波3都有数据传输，则加上第1个时间单元的数据传输，T-DAI＝3，载波0上C-DAI＝2，载波2上C-DAI＝3。依次可得第3个和第4个子帧的T-DAI和C-DAI。则最终的HARQ-ACK反馈码本大小为6比特，HARQ-ACK反馈码本为110111，对应的PDSCH或者TB为先频域后时域的顺序，即DAI值为D(1，1)的DCI对应的TB的HARQ-ACK信息为第1比特，DAI值为D(3，2)的DCI对应的TB的HARQ-ACK信息为第2比特，依次类推，注意：DAI计数是按先频域后时域计数的。
需要说明的是，虽然本申请中给出的例子中的T-DAI和C-DAI取值均为1,2,3,4,5,6，这是为了叙述方便。可选地，DCI中的T-DAI和C-DAI的取值取决于DCI中T-DAI和C-DAI域占用的比特数，例如LTE中假设T-DAI和C-DAI域均占用2比特，1用00代表、2用01代表、3用10代表、4用11代表，5又用00代表，6又用01代表，依次类推。因此在计算T-DAI具体值时需要依据循环次数，例如若T-DAI域循环了1次，且T-DAI域为01，则代表T-DAI取值为6；若T-DAI域循环了2次，且T-DAI域为10，则代表T-DAI取值为11。C-DAI类似，不再赘述，具体可如表1所示。

其中，mod()表示取余。此外，当网络设备通过RRC信令为终端设备配置了CBG级传输和CBG反馈，且配置最大CBG个数为N时，一种可能的方式，动态码本大小可以在上面得到的大小基础上乘以N(N可以为各载波配置的CBG最大值中的最大值，对于没开启CBG反馈的载波，可视为该载波的CBG最大值为1)。各TB对应位置的N比特中前M比特对应其各CBG的HARQ-ACK信息，后N-M可以为默认的NACK。
需要说明的是，以上T-DAI和C-DAI在具体应用时名称可以不限于T-DAI和C-DAI，只要它们能实现标引时间单元数量即可。此外在具体实现方案中，也可以不需要同时存在T-DAI和C-DAI，可以只需1个DAI，将其称作DAI即可，该方式特别适用于各载波各自确定HARQ-ACK信息或者只配置了1个载波的应用场景。
为了提高重传效率，网络设备可以通过RRC信令为终端设备配置CBG级传输和CBG反馈，且配置最大CBG个数为N。其中，本申请不限于通过RRC信令进行CBG级传输和CBG反馈。例如：本申请涉及的配置信令可以为RRC信令、主信息块(Master Information Block,MIB)消息、SIB消息、MAC CE信令以及其他物理层信令中的1种或者多种，下面不再赘述。
若1个TB包含C个CB，则该TB实际包括CBG的个数M＝min(C，N)，其中min()表示取最小值。M个CBG的CB数尽量均分，即前N+＝C％M个CBG各包含ceil(C/M)个CB，后N-＝M-C％M个CBG各包含floor(C/M)个CB，其中，“％”表示取余，“/”表示除以，ceil()表示向上取整，floor()表示向下取整。图5为本申请再一实施例提供的数据传输示意图，如图5所示，C＝14，M＝4，N+＝4，N-＝2。
为了支持CBG级传输，需要定义新的DCI format(本申请将其记做DCI format X)，该DCI format X包含N比特CBG传输指示(CBG Transmission Indication，CBG TI)用于指示调度了哪些CBG，例如用(也可以反过来用0表示调度CBG，1表示未调度CBG)，当1代表调度对应的CBG，0表示未调度对应的CBG，N＝4时，1010表示当前调度了第1和第3个CBG。
当网络设备通过RRC配置了开启CBG级传输和CBG反馈后，为了支持灵活的控制反馈开销、UCI译码性能和上行覆盖的问题，NR提出有可能支持动态回退到TB级反馈。具体的可以至少存在以下几种可能的动态指示方式：
1、终端检测到回退的DCI format(本申请将其记做DCI format Y)，该DCI format Y 不包含CBG TI，该回退的DCI format为系统定义的一种DCI格式，比如LTE的1A/0A，则终端判断此时是TB级传输/重传，并反馈1比特的TB级的HARQ-ACK信息。
2、终端检测到调度CBG级传输/重传的DCI format X,该DCI format X即为上述为了支持CBG级传输定义的新DCI format，该DCI format X包含N比特CBGTI，N比特CBGTI指示某个状态(比如全0)时，代表没有数据被调度，因此该状态是冗余无意义的，故而也可以利用N比特CBG TI全0指示当前为TB级传输，并反馈1比特的TB级的HARQ-ACK信息。
3、终端在公共搜索空间或者预定义/预配置的控制资源集合上监测到DCI，则终端判断此时是TB级传输/重传，并反馈1比特的TB级的HARQ-ACK信息。
为了方便起见，本申请中将上述中的1种或者多种(或者其它可能的)用于指示反馈1比特的TB级的HARQ-ACK信息的DCI形式称为第二DCI，而相应的用于指示反馈CBG级的HARQ-ACK信息的DCI称为第二DCI，即第一DCI用于指示对第一DCI调度的数据反馈CBG级的HARQ-ACK信息。第二DCI用于指示对第二DCI调度的数据反馈TB级的HARQ-ACK信息。本申请对此不再赘述。
目前基于TB级传输和TB级反馈的DCI均是针对一个TB，或者是针对MIMO中的两个码字进行的，并没有针对HARQ multiplexing的TB级反馈回退机制。而在HARQ-ACK multiplexing下，如何传输HARQ-ACK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-ACK反馈码本的发送方法、装置及设备。图6本申请一实施例提供的网络架构示意图，本申请提供的技术方案基于如图6示的网络架构，该网络架构中包括至少一个终端10，通过无线接口与网络设备20通信，为清楚起见，图2中只示出一个终端和一个网络设备。
本申请中的终端，是一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(Mobile Phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(Industrial Control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
本申请中的网络设备，是一种将终端接入到无线网络的设备，包括但不限于：演进型节点B(Evolved Node B，eNB)、家庭基站(例如，Home Evolved NodeB，或Home Node B，HNB)、基带单元(Baseband Unit，BBU)、基站(g NodeB，gNB)、传输点(Transmitting and Receiving Point，TRP)、发射点(Transmitting Point，TP)等，此外，还可以包括wifi接入点(Access Point，AP)等。
需要说明的是，本申请描述的网络架构是为了更加清楚的说明本申请的技术方案，并不构成对于本申请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，本申请提供的技术方案对于类似的技术问题，同样适用。
本申请的技术方案可以应用于但不局限于如第四代移动通信系统(4 Generation，4G)演进系统或者第五代移动通信系统(5 Generation，5G)，例如可以应用于LTE系统或者 NR系统等。
基于上述内容下面对本申请提供的HARQ反馈码本的发送方法、终端及网络设备进行详细介绍。
具体地，图7为本申请一实施例提供的HARQ-ACK反馈码本的发送方法的流程图，本申请的应用场景是上面的HARQ multiplexing。其中该方法涉及的网元为终端，如图7所示，该方法包括如下流程：
步骤S701：终端在至少一个载波的多个时间单元上检测DCI，DCI的类型为第一DCI类型或者第二DCI类型，第一DCI用于指示对第一DCI调度的数据反馈CBG级的HARQ-ACK信息，第二DCI用于指示对第二DCI调度的数据反馈TB级的HARQ-ACK信息；
步骤S702：终端向网络设备发送HARQ-ACK反馈码本，HARQ-ACK反馈码本包括DCI调度的至少一个数据的HARQ-ACK信息；
其中，HARQ-ACK反馈码本由DCI类型和HARQ-ACK反馈码本的类型确定；HARQ-ACK反馈码本的类型为半静态类型或者动态类型。
可选地，HARQ-ACK反馈码本包括第一DCI调度的至少一个数据的HARQ-ACK信息和第二DCI调度的至少一个数据的HARQ-ACK信息。
针对步骤S701进行详细说明：HARQ-ACK反馈码本的大小或者比特数由HARQ-ACK反馈码本的类型确定，或者由DCI类型和HARQ-ACK反馈码本的类型确定；HARQ-ACK反馈码本中每个HARQ-ACK信息比特具体由DCI类型确定，或者由DCI类型和HARQ-ACK反馈码本的类型确定。例如：若某TB由第一DCI调度，则该TB的HARQ-ACK信息为CBG级的HARQ-ACK信息。若某TB由第二DCI调度，则该TB的HARQ-ACK信息为TB级的HARQ-ACK信息。
其中，所谓CBG级的HARQ-ACK信息是指该HARQ-ACK信息包含DCI调度的TB包括的CBG的HARQ-ACK信息，因此通常CBG级的HARQ-ACK信息占用多比特，每个CBG对应1比特的HARQ-ACK信息，例如假设网络设备为配置了最大CBG个数为N，组成TB的CBG个数为M，则反馈N比特的HARQ-ACK信息，N比特中前M比特中每一比特对应一个CBG的HARQ-ACK信息(当该CBG包含的所有CB都译码成功则该比特为ACK，否则为NACK)，后N-M比特可选地为NACK(或者其它可能的值，比如为ACK，本申请对此不做限制)。
所谓TB级的HARQ-ACK信息是指该HARQ-ACK信息是针对TB的HARQ-ACK信息，该TB级的HARQ-ACK信息占用1比特(当该TB包含的所有CB都译码成功且TB的CRC校验通过则该比特为ACK，否则为NACK)。例如尽管假设网络设备为配置了最大CBG个数为N，该TB实际只需占用1比特来发送TB级的HARQ-ACK信息。
本申请中，终端在上述至少一个载波的多个时间单元上检测DCI，包括如下几种可能：在一个载波上的多个时间单元上检测DCI，或者在多个载波上的多个时间单元上检测DCI等。
针对步骤S702进行详细说明：终端根据检测到的DCI向网络设备发送HARQ-ACK反馈码本。本申请中，DCI具有现有技术的功能，即DCI可以实现数据调度。
其中，当终端在至少一个载波的多个时间单元上检到的DCI都是第一DCI时，该 HARQ-ACK反馈码本为现有技术中CBG级的HARQ-ACK反馈码本。当终端在至少一个载波的多个时间单元上检测到的DCI至少一个是第二DCI时，该HARQ-ACK反馈码本中由第二DCI指示的第二数据对应位置的HARQ-ACK信息是TB级的HARQ-ACK信息。
本申请提供一种HARQ-ACK反馈码本的发送方法，本申请考虑到在至少一个载波的多个时间单元上检测到的DCI的类型，当该DCI类型为第二DCI类型时，该HARQ-ACK反馈码本包括由第二DCI调度的第二数据的HARQ-ACK信息。即本申请提供了基于HARQ multiplexing场景下的TB级反馈回退机制。
下面以一个载波和一个码字情况为例(对于多个载波，2个码字的情况与一个载波，一个码子的情况类似，本申请对此不再赘述)，当HARQ-ACK反馈码本包括基于第一DCI调度的第一数据对应的HARQ-ACK信息和基于第二DCI调度的第二数据对应的HARQ-ACK信息时，该第二数据对应的HARQ-ACK信息在HARQ-ACK反馈码本的排布情况以及基于每种排布确定HARQ-ACK反馈码本的方法：
第一种情况：若第一数据基于第一DCI调度，则HARQ-ACK反馈码本中第一数据对应的N比特中前M比特为第一数据包括的码块组CBG级的HARQ-ACK信息；N比特中后N-M比特可选地为否定回答NACK；N为网络设备为该数据配置的最大CBG个数(其中，网络设备为同一载波上的所有数据配置的最大CBG个数相同，因此本申请中涉及的为数据配置的最大CBG个数即为为该数据所在的载波配置的最大CBG个数)，M为该DCI调度的TB实际包括的CBG个数；若第二数据由第二DCI调度，HARQ-ACK反馈码本中第二数据对应的N比特中前1比特为第二数据的TB级的HARQ-ACK信息；N比特中后N-1比特中每一比特为NACK或者每一比特为TB级的HARQ-ACK信息。
通过该方式，网络设备可以灵活利用第二DCI指示终端设备回退到TB级反馈。进一步的，终端设备将N-1比特填为默认的NACK，总的码本大小和不回退时一样，由于引入了预知的NACK，从而有助于网络设备解码UCI，进而提高上行UCI的覆盖/解码性能。此外，由于总的码本大小不变，各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。
其中，第一数据为至少一个数据中基于第一DCI调度的任一个数据，第二数据为至少一个数据中基于第二DCI调度的任一个数据。
1、该HARQ-ACK反馈码本可以是半静态HARQ-ACK反馈码本，若在某个载波上的HARQ复用窗内的某个时间单元上检测到第二DCI，则由第二DCI调度的第二数据对应位置的N比特中前1比特为该第二数据对应的TB级的HARQ-ACK信息，后N-1中每一比特可以为默认的NACK或者每一比特为TB级的HARQ-ACK信息。例如：图8为本申请一实施例提供的数据传输示意图，图9A为本申请一实施例提供的HARQ-ACK反馈码本示意图，图9B为本申请另一实施例提供的HARQ-ACK反馈码本示意图，结合图8、图9A和图9B进行说明：假设配置的载波数为1，网络设备为该载波开启CBG传输和反馈模式且通过RRC配置的N＝2，该载波的HARQ复用窗大小为4，且采用1码字传输，HARQ复用窗内监测到的数据传输情况如图8所示，则终端设备生成如图9A或者图9B所示的半静态HARQ-ACK反馈码本：该码本大小为8比特，第1，2比特对应第1个TB的HARQ-ACK信息均为NACK(因为用于调度该TB的DCI丢失)，第3，4比特对应第2个TB(由第 一DCI调度，假设该TB的CBG个数为2)的CBG级的HARQ-ACK信息，第5比特对应第3个TB(由第二类DCI调度)的TB级的HARQ-ACK信息；第6比特可以为默认的NACK，或者重复为第3个TB的TB级的HARQ-ACK信息；第7，8比特对应第4个TB(由第一DCI调度，假设该TB的CBG个数为2)的CBG级的HARQ-ACK信息。
其中，所谓“第二数据对应位置”、“第一数据对应位置”取决于半静态反馈码本的编排方式。例如LTE下该位置取决于承载“第一数据”、“第二数据”的载波号和时间单元在反馈窗内的位置，例如对于图8，承载TB1的时间单元为该载波上反馈窗内的第一个位置，因此第1个N比特对应该TB的CBG级HARQ-ACK信息。承载TB4的时间单元为该载波上反馈窗内的第四个位置，因此第4个N比特对应该TB的CBG级HARQ-ACK信息。当然别的编排方式对于本申请也适用，本申请对此不做任何限制。
需要说明的是，上述是以单载波为例进行说明的，可选地，对于多载波的情况，每个载波都适用于上述单载波示例，本申请对多载波情况不再赘述。
对于多载波多码字，或者单载波多码字的情况，每个码字可以视为上述的一个TB，针对HARQ复用窗中的所有码字(或者称为所有的TB)也可以采用上述方法。本申请对此不再赘述。
特别强调的是，上述第一数据和第二数据是同一载波上的数据。对于配置了多载波的情况，第一数据和第二数据也可以是不同载波上的数据。
进一步地，当HARQ-ACK反馈码本是半静态HARQ-ACK反馈码本时，HARQ-ACK反馈码本的大小至少基于至少一个载波的载波数、多个时间单元的时间单元数以及网络设备为每个载波配置的最大CBG个数确定。
例如：假设所有载波都是采用单码字传输，对于载波i，对应Ti个时间单元，并且载波i对应的最大CBG个数为Ni，假设共存在L个载波，则最终确定的半静态HARQ-ACK反馈码本大小为T1*N1+T2*N2+……TL*NL。其中，N1，N2……NL可以是通过同一条信令配置的，也可以是通过不同信令配置的。各载波的时间单元集合大小Ti也可以相同或者不同。本申请不做限定。
例如：考虑到MIMO场景(即多码字传输的情况)，对于载波i，对应Ti个时间单元，并且载波i对应的最大CBG个数为Ni(假设同一载波的2个码字的配置的最大CBG个数相同)，假设共存在L个载波，并且载波i对应的码字个数为Ki(第i个载波时间单元内至少存在1个2码字传输，且不采用HARQ-ACK bundling方式，则Ki＝2，否则Ki＝1)，最终确定的半静态HARQ-ACK反馈码本大小为T1*N1*K1+T2*N2*K2+……TL*NL*KL。
2、该HARQ-ACK反馈码本可以是动态HARQ-ACK反馈码本，针对单载波情况进行说明：第一DCI和第二DCI都存在DAI域，该DAI域统一计数。图10为本申请一实施例提供的数据传输示意图，图11为本申请一实施例提供的HARQ-ACK反馈码本示意图，结合图10和图11进行说明：若在某个载波上的，HARQ复用窗内的某个时间单元上检测到第二DCI，则由第二DCI调度的第二数据对应位置的N比特中前1比特对应其TB级的HARQ-ACK信息，后N-1比特中每一比特可以为默认的NACK或者为TB级的HARQ-ACK信息。
所谓“第二数据对应位置”、“第一数据对应位置”取决于动态反馈码本的编排方式。例如LTE下该位置取决于调度“第一数据”、“第二数据”的DCI中的DAI取值，例如对于图 10，调度TB3的DCI中的DAI值等于3，因此第3个N比特对应该TB的CBG级HARQ-ACK信息。调度TB4的DCI中的DAI值等于4，因此第4个N比特中的第1比特对应该TB的TB级HARQ-ACK信息。当然别的编排方式对于本申请也适用，本申请对此不做任何限制。一种可能的方式，对于单载波DCI可能只存在1个DAI域。对于多载波DCI可能存在C-DAI域和T-DAI域，对应位置由C-DAI确定。
需要说明的是，上述是以单载波为例进行说明的，实际上，对于多载波的情况，每个载波都适用于上述单载波示例，本申请对多载波情况不再赘述。
对于多载波多码字，或者单载波单码字的情况，每个码字可以视为上述的一个TB，针对HARQ复用窗中的所有码字(或者称为所有的TB)也可以采用上述方法，本申请对此不再赘述。
特别强调的是，上述第一数据和第二数据是同一载波上的数据。对于配置了多载波的情况第一数据和第二数据也可以是不同载波上的数据。
进一步地，当HARQ-ACK反馈码本是动态HARQ-ACK反馈码本时，HARQ-ACK反馈码本的大小至少基于在DCI中的DAI值以及网络设备为每个载波配置的最大CBG个数确定。
其中，对于单载波单码字的情况，HARQ-ACK反馈码本的大小为最后一个DAI值与网络设备为该载波配置的最大CBG个数N乘积。
例如：对于载波i，对应的最大DAI值为4，且为该载波配置的最大CBG个数为5，则最终确定的HARQ-ACK反馈码本的大小为20。
对于多载波单码字的情况，HARQ-ACK反馈码本的大小为最后一个T-DAI值与网络设备为载波配置的最大CBG个数乘积。
考虑到MIMO场景(即多码字传输的情况)，HARQ-ACK反馈码本的大小由在DCI中的DAI值、网络设备为每个载波配置的最大CBG个数以及码字个数确定。
例如：对于载波i，载波i对应的最大CBG个数为5，最大DAI为4，且码字个数为2(至少1个载波上的时间窗内的1个时间单元承载2码字，且不采用HARQ-ACK bundling方式，则码字个数为2，否则为1)，则最终确定动态HARQ-ACK反馈码本大小为5*4*2＝40。
第二种情况：HARQ-ACK反馈码本中包括的所有HARQ-ACK信息均为CBG级的HARQ-ACK信息。
1、当网络设备配置半静态码本模式时，尽管终端设备在HARQ复用窗口中检测到第二DCI，终端设备仍然采用CBG级的反馈。即在HARQ-ACK mutliplexing情况下，RRC配置的CBG反馈和CBG传输比第二DCI具有更高的优先级，而只有在非HARQ-ACK mutliplexing时第二DCI指示的TB级回退才生效。
这种情况下，确定HARQ-ACK反馈码本的大小与现有技术中确定HARQ-ACK反馈码本的大小方法相同，因为该HARQ-ACK反馈码本实际上是CBG级的HARQ-ACK反馈码本。通过该方式，由于总的码本大小不变，各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。
该情况还适用于多载波的情况，或者多载波多码字的情况等，本申请对此不再赘述。
2、当网络设备配置动态码本模式时，尽管终端设备在HARQ复用窗口中检测到第二 DCI，终端设备仍然采用CBG级的反馈。即RRC配置的CBG反馈和CBG传输比第二DCI具有更高的优先级，而只有在非HARQ-ACK mutliplexing时第二DCI指示的TB级回退才生效。
同样，这种情况下，确定HARQ-ACK反馈码本的大小与现有技术中确定HARQ-ACK反馈码本的大小方法相同，因为该HARQ-ACK反馈码本实际上仍然是CBG级的HARQ-ACK反馈码本。
该情况还适用于多载波的情况，或者多载波多码字的情况等，本申请对此不再赘述。
第三种情况：终端确定HARQ-ACK反馈码本的大小；若确定的HARQ-ACK反馈码本的大小小于预设阈值，则HARQ-ACK反馈码本中第二数据对应的N比特中前1比特为第二数据的TB级的HARQ-ACK信息；N比特中后N-1比特中每一比特为NACK或者每一比特为TB级的HARQ-ACK信息；若确定的HARQ-ACK反馈码本的大小大于或者等于预设阈值，HARQ-ACK反馈码本中第二数据对应的N比特中前M比特为第二数据的CBG级的HARQ-ACK信息；N比特中后N-M比特可选地为否定回答NACK；N为网络设备为第二数据配置的最大CBG个数；M为第二数据对应TB实际包括的CBG个数；其中，第二数据为至少一个数据中由第二DCI调度的任一个数据。
可选地，终端确定半静态HARQ-ACK反馈码本的大小，该预设阈值可以是12比特，如果半静态HARQ-ACK反馈码本的大小小于12比特时，则采用TB级反馈，即HARQ-ACK反馈码本中第二数据对应的N比特中前1比特为第二数据的TB级的HARQ-ACK信息；N比特中后N-1比特中每一比特为NACK或者每一比特为TB级的HARQ-ACK信息；若确定的HARQ-ACK反馈码本的大小大于或者等于12比特，则采用CBG反馈，即HARQ-ACK反馈码本中第二数据对应的N比特中前M比特为第二数据的CBG级的HARQ-ACK信息；N比特中后N-M比特为否定回答NACK。采用本实施例的原因是：当UCI小于12比特时，UCI采用RM编码，基于第二DCI指示采用回退的TB级反馈可以引入N-1比特的预知NACK，有助于UCI的解码，进而提高上行UCI的覆盖/解码性能；而当UCI大于等于12比特时，UCI采用Polar编码，基于第二DCI指示采用回退的TB级反馈，引入N-1比特的预知NACK，无助于UCI的解码，因此第二DCI指示的TB级反馈回退可以不生效。
需要说明的是，第三种情况实际是在第一种情况和第二种情况中选择一种执行方案，并且第三种情况既适用于半静态HARQ-ACK反馈码本的情况，也适用于动态HARQ-ACK反馈码本的情况。如果确定的HARQ-ACK反馈码本的大小小于预设阈值，则第三种情况为上述第一种情况，基于此，确定HARQ-ACK反馈码本的大小方法可以采用第一种情况中提供的方法。如果确定的HARQ-ACK反馈码本的大小大于或者等于预设阈值，则第三种情况为上述第二种情况，基于此，确定HARQ-ACK反馈码本的大小方法可以采用第二种情况中提供的方法。本申请对此不再赘述。
该方案还还适用于多载波的情况，或者多载波多码字的情况等，本申请对此不再赘述。
第四种情况，若HARQ-ACK反馈码本的类型为动态类型，则HARQ-ACK反馈码本包括第一子码本和/或第二子码本；其中，第一子码本包括基于第一DCI调度的数据的CBG级的HARQ-ACK信息，第二子码本包括基于第二DCI调度的数据的TB级的HARQ-ACK信息。
可选地，第一子码本中第一数据对应位置的N比特中前M比特为第一数据包括的CBG级的HARQ-ACK信息；N比特中后N-M比特为NACK；N为网络设备配置的最大CBG个数；M为第一数据对应TB包括的CBG个数；第二子码本中第二数据对应位置的1比特为第二数据的TB级的HARQ-ACK信息；其中，第一数据为至少一个数据中由第一DCI调度的任一个数据，第二数据为至少一个数据中由第二DCI调度的任一个数据。
一种可能的实现方式，第一DCI和第二DCI都存在DAI域，该DAI域单独分开计数。对第一DCI调度的数据生成第一子码本，对于第二DCI调度的数据生成第二子码本，其中，第一子码本和第二子码本可以承载在2个UCI上分别反馈，也可以合并成1个UCI，比如串联成1个UCI反馈(可选地，第一子码本在第二子码本之前，或者第二子码本在第一子码本之前)。图12为本申请一实施例提供的数据传输示意图，如图12所示，通过第一DCI调度的TB包括：TB2和TB4，它们的DAI统一计数，通过第二DCI调度的TB包括：TB3和TB5，它们的DAI统一计数。其中用于调度TB1的DCI丢失，图13为本申请一实施例提供的HARQ-ACK反馈码本示意图，如图13所示，该第一子码本中TB2以及TB4(第一数据)对应位置的N比特分别为TB2以及TB4的CBG级HARQ-ACK信息；第二子码本中TB3(第二数据)对应位置的1比特为第二数据的TB级的HARQ-ACK信息；其中，第一数据为至少一个数据中由第一DCI调度的任一个数据，第二数据为至少一个数据中由第二DCI调度的任一个数据。
通过上述第一子码本和第二子码本的排布，一方面由于第二子码本中每个第二数据对应的HARQ-ACK信息均占用1比特，而无需占用N比特，从而可以降低HARQ-ACK反馈码本的开销。另一方面将第一DCI的DAI和第二DCI的DAI分开计数，各自产生第一子码本和第二子码本，第一子码本和第二子码本分开排布，从而可以防止当存在DCI丢失的情况时，由于第一子码本占用比特数不变，各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况(如图中的第一个DCI丢失了)，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。进一步的，在第二子码本中各TB对应的HARQ-ACK信息位置也是确定的，因此即使存在DCI丢失的情况，其他数据的HARQ-ACK信息位置和编排也不受影响，从而保证能够正确接收其他数据的HARQ-ACK信息，进而提高系统的鲁棒性。
可选地，第一子码本大小至少基于第一DCI中的DAI值和N确定；第二子码本大小至少基于第二DCI中的DAI值确定。
具体地，当采用单载波单码字进行数据传输时，第一子码本大小为第一DCI中最后一个DAI值和N的乘积；当采用单载波进行数据传输，且为2个码字传输情况(该载波上的时间窗内的至少1个时间单元承载2码字，且不采用HARQ-ACK bundling方式则码字个数为2，否则为1)时，第一子码本大小为第一DCI中最后一个DAI值与N和2的乘积。当采用多载波进行数据传输时，第一子码本大小为第一DCI中所有DAI中的最后一个T-DAI值和N的乘积。同样当采用多载波进行数据传输，且为2个码字传输情况(至少1个载波上的时间窗内的1个时间单元承载2码字，且不采用HARQ-ACK bundling方式则码字个数为2，否则为1)时，第一子码本大小为第一DCI中所有DAI中的最后一个DAI值与N以及2的乘积。当采用单载波单码字进行数据传输时，第二子码本大小为第二DCI 中最后一个DAI值；当采用单载波进行数据传输，且为2个码字传输情况(该载波上的时间窗内的至少1个时间单元承载2码字，且不采用HARQ-ACK bundling方式则码字个数为2，否则为1)时，第二子码本大小为第二DCI中最后一个DAI值与2的乘积。当采用多载波进行数据传输时，第二子码本大小为第二DCI中所有DAI中的最后一个T-DAI值。同样当采用多载波进行数据传输，且为2个码字传输情况(至少1个载波上的时间窗内的1个时间单元承载2码字，且不采用HARQ-ACK bundling方式则码字个数为2，否则为1)时，第二子码本大小为第二DCI中所有DAI中的最后一个DAI值与2的乘积。
第五种情况，若HARQ-ACK反馈码本的类型为半静态类型，且检测到第二DCI，终端设备反馈至少2个UCI，其中所述至少2个UCI至少包括1个UCI为半静态码本，该半静态码本生成方式可以参考第一种情况中的第1点；另一种可能的方式，该半静态码本中第二DCI调度的第二数据对应的N比特可以都设置为NACK，图14A为本申请一实施例提供的HARQ-ACK反馈码本示意图，如图14A所示，该UCI中包括基于第一DCI调度的第一数据的CBG级反馈，其中，由于用于调度该TB1的DCI丢失，因此前两个NACK是TB1对应的CBG级反馈，图14B为本申请一实施例提供的HARQ-ACK反馈码本示意图，如图14B所示，此外，所述至少2个UCI中还包括基于第二DCI调度的第二数据的TB级反馈。其中，TB3-ACK表示对TB3的TB级反馈。
若HARQ-ACK反馈码本的类型为动态类型，且检测到第二DCI，终端设备反馈至少2个UCI，其中所述至少2个UCI至少包括1个UCI为动态码本，该动态码本生成方式可以参考第一种情况中的第二点；另一种可能的方式，该动态码本中第二DCI调度的第二数据对应的N比特可以都设置为NACK。此外，所述至少2个UCI中还包括基于第二DCI调度的第二数据的TB级反馈。
第六种情况，若HARQ-ACK反馈码本的类型为动态类型，第一DCI和第二DCI统一计数。与第一种情况不同的是，DAI计数为实际调度的CBG个数或者反馈的比特数(而不是调度的PDSCH/TB个数)。对于第二DCI，由于其需要反馈TB级的HARQ-ACK，因此DAI加1即可(等效于在1码字时只需反馈1比特，对于2码字时可选地加2即只需反馈2比特)。终端若检测到第二DCI，则该DCI的DAI值对应位置反馈1比特(1码字情况)或者2比特(2码字情况)为该第二DCI调度数据的TB级HARQ-ACK。
需要说明的是，上述是以单载波为例进行说明的，实际上，对于多载波的情况，每个载波都适用于上述单载波示例，本申请对多载波情况不再赘述。
对于多载波多码字，或者单载波单码字的情况，每个码字可以视为上述的一个TB，针对HARQ复用窗中的所有码字(或者成为所有的TB)也可以采用上述方法，本申请对此不再赘述。
综上，本申请提供一种HARQ-ACK反馈码本的发送方法，本申请考虑到在至少一个载波的多个时间单元上检测到的DCI的类型，当该DCI类型为第二DCI类型时，该HARQ-ACK反馈码本包括由第二DCI调度的第二数据的HARQ-ACK信息。即本申请提供了HARQ-ACK multiplexing场景下的TB级反馈回退机制。进一步地，针对HARQ-ACK反馈码本，本申请可以有效的确定由第二DCI调度的第二数据的HARQ-ACK信息的具体排布以及有效的确定HARQ-ACK反馈码本的大小。
需要说明的是，本申请给的例子为了便于阐述，都是假设单载波单码字配置的情况。 而且没有考虑半静态调度(Semi-Persistent Scheduling，SPS)传输。若SPS PDSCH传输被激活，且在时间窗内终端需要接收SPS PDSCH，则HARQ-ACK码本信息还可以包括SPS PDSCH反馈译码结果信息，即实际的码本大小需要在上文描述计算结果后加上SPS PDSCH反馈译码结果的比特数，码本信息也需要在上文描述的码本信息后加上SPS PDSCH反馈译码结果。
需要说明的是本申请涉及的码本类型包括动态码本和半静态码本，本申请对码本类型的名称不做限制，比如码本类型包括：第一码本类型或者第二码本类型。具体地，第一码本(或者半静态码本)的大小和实际调度的PDSCH/TB/CBG个数无关，而第二码本(或者动态码本)的大小和实际调度的PDSCH/TB/CBG个数相关。在LTE中，通过参数cbgcodebooksizeDetermination＝cc(表示码本类型为半静态码本类型)或者cbgcodebooksizeDetermination＝DAI(表示码本类型为动态码本类型)来配置码本类型。NR中可以类似，或者别的名称/参数配置。此外，上述实施例都是以配置1个载波为例，对于配置多载波情况，可选地，为每个载波或者载波组分别独立配置为第一码本类型或者第二码本类型，每个载波或者载波组的码本信息确定方式也可选地分别采用上述情况1～6的任意情况，每个载波或者载波组的的码本也可选地可以独自传输或者级联/串联成一个码本一起传输。对于某些系统，也可以只支持一种码本类型(即只存在第一码本类型或者第二码本类型，无需信令配置)。
