具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、非授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、未来的5G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，还将支持例如设备到设备(Device to Device，D2D)通信、机器到机器(Machine to Machine，M2M)通信、机器类型通信(Machine Type Communication，MTC)、以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统也可以应用于载波聚合(Carrier Aggregation，CA)场景、双连接(Dual Connectivity，DC)场景、独立(Standalone，SA)布网场景等。
图1是本申请实施例应用的一种可能的无线通信系统的示意图。该无线通信系统100可以包括网络设备110。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。
可选地，该网络设备100可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、未来网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该无线通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。
终端设备120可以是移动的或固定的。
可选地，终端设备120可以指用户设备、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。其中，可选地，终端设备120之间也可以进行终端直连(Device to Device，D2D)通信。
网络设备110可以为小区提供服务，终端设备120通过该小区使用的传输资源，例如频域资源，或者说频谱资源，与网络设备110进行通信。该小区可以是网络设备110对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
图1示例性地示出了一个网络设备和两个终端设备，但本申请并不限于此。该无线通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备。此外，该无线通信系统100还可以包括网络控制器、移动性管理实体等其他网络实体。
应理解，图1所示的系统可以应用于授权频谱或非授权频谱。
还应理解，非授权频谱是国家和地区划分的可用于无线电设备通信的频谱，该频谱通常被认为是共享频谱，即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求，就可以使用该频谱，不需要向政府申请专有的频谱授权。
为了让使用非授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存，一些国家或地区规定了使用非授权频谱必须满足的法规要求。例如，通信设备遵循“先听后说(Listen Before Talk，LBT)”原则，即通信设备在非授权频谱的信道上进行信号发送前，需要先进行信道侦听，只有当信道侦听结果为信道空闲时，该通信设备才能进行信号发送；如果通信设备在非授权频谱的信道上的信道侦听结果为信道忙，该通信设备不能进行信号发送。为了保证公平性，在一次传输中，通信设备使用非授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)。
下面对HARQ反馈过程进行说明。
NR系统中支持动态确定HARQ反馈时序。基站通过下行控制信息(Downlink Control Information，DCI)调度终端设备进行PDSCH接收，其中，该DCI中包括用于传输该PDSCH对应的HARQ码本的物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源的指示信息。具体地，该指示信息包括：
PUCCH资源指示(PUCCH resource indicator)：用于确定PUCCH资源；
HARQ时序指示：用于动态确定PUCCH资源的时域位置。其中，该HARQ时序指示信息用于确定预配置的HARQ时序集合中的取值。例如，该HARQ时序指示信息为000时，指示HARQ时序集合中的k0，该HARQ时序指示信息为001时，指示HARQ时序集合中的k1，等等。
如果是动态码本反馈，该DCI中还包括以下信息：
下行分配指示(Downlink assignment index，DAI)，该DAI包括DAI计数信息和/或DAI总数信息，其中，DAI计数信息用于指示当前被调度的PDSCH是当前HARQ反馈窗中的第几个PDSCH，DAI总数信息用于指示当前HARQ反馈窗中一共调度了多少个PDSCH。
终端设备根据上述信息可以确定用于反馈该HARQ码本的PUCCH资源和该HARQ码本在该PUCCH资源上传输的码本中的位置。
可选地，终端设备采用动态码本进行HARQ码本反馈时，可以在单载波和多载波场景下进行动态码本反馈。
即，动态码本具体可以分为以下两种情况：
情况1：单载波场景。
网络设备在向终端设备发送PDSCH时，会同时向终端设备发送DAI计数(counter DAI，C-DAI)信息，该DAI计数信息通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)发送给终端设备，用于终端设备确定HARQ反馈码本，即该DAI计数用于指示当前PDCCH调度的PDSCH是该HARQ反馈窗口内的第几个PDSCH，其中，PDSCH的排序方式是根据PDCCH的检测机会顺序排序的。为了减少DAI计数信息的比特数，可以使用取模的方式计数，例如，如果DAI计数的比特数为2比特，那么DAI计数的取值就模4；如果DAI计数的比特数为3比特，DAI计数的取值就模8。如图2所示，在HARQ码本反馈窗口内一共包括8个时隙，每个时隙上都配置有PDCCH检测机会，网络设备在该8个PDCCH检测机会中的第1、3、4、5、7个PDCCH检测机会上调度终端设备接收PDSCH，假设DAI计数的比特数为2比特，相应地，该5个时隙上的PDSCH对应的DAI计数分别为00,01,10,11,00。
对于每个PDSCH，其对应的HARQ码本反馈比特数K可以是高层配置的，例如，如果终端设备被调度的PDSCH中至少一个PDSCH支持2个码字，那么所有的PDSCH对应的HARQ码本比特数都为2比特(K＝2)。又例如，在支持基于码块组(Code block group，CBG)的反馈的情况下，假设一个PDSCH对应的最大HARQ码本比特数为8比特，所有PDSCH中每个PDSCH对应的HARQ码本比特数均为8比特(K＝8)。
在图2的示例中，假设K＝2，对应两个码字。当终端设备收到该5个PDSCH后，该终端设备可以确定该HARQ码本反馈窗口内的码本大小为10比特，如下表1所示：
表1
Figure PCTCN2019085386-appb-000001
当终端设备只收到5个PDSCH中的部分PDSCH，例如终端设备没有收到DAI计数为01的PDSCH，在这种情况下，在收到DAI计数为00的PDSCH后面收到了DAI计数为10的PDSCH，此 时，终端设备可以判断自己丢掉了DAI计数为01的PDSCH，因此会在对应位置填充否定应答(Negative Acknowledgement，NACK)，如下表2所示：
表2
Figure PCTCN2019085386-appb-000002
应理解，如果PDSCH中只有一个码字，那么码字1对应的HARQ码本为NACK。
情况2：多载波场景。
网络设备在向终端设备发送PDSCH时，会同时向终端设备发送DAI计数和DAI总数(total DAI，T-DAI)两个DAI信息，该两个DAI信息通过PDCCH发送给终端设备，用于终端设备确定HARQ反馈码本，其中，该DAI计数用于指示当前PDCCH调度的PDSCH是该HARQ反馈窗口内的第几个PDSCH，该DAI总数用于告诉终端设备该HARQ反馈窗口内截止到当前为止一共有多少个HARQ码本。PDSCH的排序方式是根据PDCCH的检测机会顺序排序的，具体地，可以按照先频域后时域的顺序。为了减少DAI计数(或DAI总数)信息的比特数，可以使用取模的方式计数，例如，如果DAI计数(或DAI总数)的比特数为2比特，那么DAI计数(或DAI总数)的取值就模4；如果DAI计数(或DAI总数)的比特数为3比特，DAI计数(或DAI总数)的取值就模8。
如图3所示，终端设备被配置了2个载波，在HARQ码本反馈窗口内一共包括8个时隙，每个载波的每个时隙上都配置有PDCCH检测机会，那么PDCCH的检测机会排序为载波#1的第1个时隙，载波#2的第1个时隙，载波#1的第2个时隙，载波#2的第2个时隙，…，载波#1的第8个时隙，载波#2的第8个时隙。网络设备在该16个PDCCH检测机会中的第1、2、6、7、8、9、13、14个时隙上调度终端设备接收PDSCH，假设DAI计数和DAI总数的比特数分别为2比特，相应地，该8个时隙上的PDSCH对应的DAI计数和DAI总数如图3所示。
在图3的示例中，假设K＝2，对应两个码字。假设终端设备没有收到第4个时隙上的PDSCH，该终端设备可以确定该HARQ码本反馈窗口内的码本如下表3所示：
表3
Figure PCTCN2019085386-appb-000003
应理解，PDCCH调度的PDSCH可以和PDCCH在同一个时隙上，也可以不和PDCCH在同一个时隙上，本申请实施例并不限定。
当NR系统应用到非授权频段上时，UE在非授权载波上接收到PDSCH后，需要在非授权载波上发送该PDSCH对应的HARQ反馈。
目前在非授权频段上，HARQ时序指示信息除了可以用于确定传输该PDSCH对应的HARQ的PUCCH时域资源，还可能用于指示该PDSCH对应的HARQ先不进行反馈的状态。例如，预配置的HARQ时序集合中包括表示无效资源指示的取值k L，该HARQ时序指示信息为111时，指示HARQ时序集合中的k L，表示对应的PUCCH资源暂时无法确定。
另外，为了灵活反馈非授权频段上的PDSCH对应的HARQ信息，基站可以对调度的PDSCH进行分组，并通过显示信令指示PDSCH的分组信息，以使UE在接收到PDSCH后根据不同的分组进行对应的HARQ反馈。如果UE的某组HARQ信息在某次传输时由于LBT失败未能进行传输，或基站在某个PUCCH资源上未能检测到期待UE传输的某组HARQ信息，基站可以通过DCI触发UE进行该组HARQ信息的重传。其中，UE在进行某组HARQ信息重传时可以保持和初传同样的码本大小，也可以在重传时增加新的HARQ信息。
图4和图5是UE需要根据基站的分组进行HARQ反馈时PDSCH组和反馈组的示意性框图。
UE需要根据基站的分组进行HARQ反馈时，其具体反馈方式可以包括以下两种：
方式1：
基站分组后，在初传或重传该组里包括的HARQ信息时，HARQ码本的大小不变。或者说，如果某组里的PDSCH对应的HARQ被指示一个有效上行资源用于传输后，该组内不再增加新的PDSCH。在方式1中，一个PUCCH资源上可以反馈多个组包括的HARQ信息。例如，请参见图4，PUCCH 0可以反馈组0包括的HARQ信息，PUCCH 1上可以反馈组0和组1包括的HARQ信息。
方式2：
基站分组后，在初传或重传该组里包括的HARQ信息时，HARQ码本的大小可以不同。或者说，如果某组里的PDSCH对应的HARQ被指示一个有效上行资源用于传输后，该组内还可以增加新的 PDSCH。例如，请参见图5，PUCCH 0和PUCCH 1上可以分别反馈组0包括的HARQ信息。
可选地，对于多个组中传输的PDSCH对应的DAI可以是统一计数的。
图6是本申请实施例的信道组、DAI和反馈组的位置关系的示意性框图。
应理解，本申请实施例中是一个载波为例进行描述的，多个载波的情况可以采用类似的方法。
请参见图6，组编号为#0的PDSCH组包括PDSCH 0、PDSCH 1、PDSCH 2、PDSCH 3和PDSCH4。组编号为#1的PDSCH组包括PDSCH 5、PDSCH 6、PDSCH 7和PDSCH 8。其中，PDSCH 0对应的DAI至PDSCH 8对应的DAI是连续计数的。

应当理解，HARQ码本也可以称为HARQ信息、HARQ-ACK码本或HARQ-ACK信息。
可选地，所述信道组可以是下行信道组。例如所述信道组是PDSCH对应的信道组，或者是PDCCH对应的信道组。
可选地，所述第一上行资源用于反馈多个信道组中至少一个信道组对应的第一HARQ码本，所述第一HARQ码本包括所述至少一个信道组中每个信道组内的信道对应的HARQ码本。例如，所述信道组是PDSCH信道组，则所述第一HARQ码本包括所述至少一个PDSCH信道组中每个PDSCH信道组内的PDSCH对应的HARQ码本。
可选地，所述至少一个信道组中的第一个信道组内的第一个PDSCH对应的第一DAI不是初始值时，所述第一HARQ码本在起始位置的信息为占位信息。

图8是本申请实施例的信道组、DAI和反馈组的位置关系的示意性框图。
下面结合图8对所述至少两个信道组为被触发反馈的DAI计数连续的信道组时，所述第一HARQ 码本进行详细说明。
请参见图8，如果UE需要在PUCCH 1资源上只反馈组1包括的HARQ信息，当UE没有接收到PDSCH 1(或PDSCH 2，这里以没有收到PDSCH 1为例)时，UE不能确定PDSCH 1属于组0还是组1，那么UE可能认为组1包括的PDSCH是2、3、4，也可能认为组1包括的PDSCH是1、2、3、4，即UE将无法确定组1包括的PDSCH的起点，从而无法确定组1对应的HARQ码本。(一个上行资源上只反馈一个组对应的HARQ信息时的主要问题)
在一种可能的实现方式中，UE在进行一个上行资源例如PUCCH资源上的HARQ信息的反馈时，对于该上行资源上反馈的HARQ信息总是从00开始准备码本。通过这种方式，基站和UE可以确定一个PUCCH资源上反馈的HARQ码本的大小。
结合图8来说，如果一个上行资源上只反馈一个组的HARQ码本，例如PUCCH 0上反馈组0，PUCCH 1上反馈组1，那么无论UE收到的该组内的第一个PDSCH对应的DAI是什么，UE都从DAI为0开始准备HARQ码本。在本申请实施例中，以一个PDSCH的反馈码本对应两个码字为例：
对于PUCCH 0上传输的HARQ码本中包括的组0里的PDSCH对应的HARQ码本如表4所示：
表4
Figure PCTCN2019085386-appb-000004
对于PUCCH 1上传输的HARQ码本中包括的组1里的PDSCH对应的HARQ码本如表5所示：
表5
Figure PCTCN2019085386-appb-000005
在PUCCH 1上的反馈中，通过从DAI计数为0开始准备HARQ码本，无论UE没有接收到PDSCH1还是没有接收到PDSCH 2，对于UE正确接收到的PDSCH对应的码本位置，基站和UE的理解都是一致的，进而实现HARQ码本的传输。
如果一个上行资源上反馈至少两个组的HARQ码本，一种情况中可以限定基站只能触发连续的多个组的HARQ码本反馈，以避免DAI的丢失导致的基站和UE对HARQ码本的理解不一致。例如PUCCH 2上反馈组1和组2(这里组1和组2是连续的，但限定的是发送组连续，不一定是组编号连续)，PUCCH 3上反馈组1、组2和组3，UE可以根据基站调度的顺序准备码本。UE在准备该PUCCH资源上传输的HARQ码本时，无论排序的第一个组内的第一个PDSCH对应的DAI是什么，UE都从DAI为0开始准备。由于是连续组的码本反馈触发，UE根据DAI的顺序准备HARQ码本，不需要再补充占位信息。
对于PUCCH 2上传输的HARQ码本中包括的组1和组2里的PDSCH对应的HARQ码本如表6所示：
表6
Figure PCTCN2019085386-appb-000006
对于PUCCH 3上传输的HARQ码本中包括的组1、组2和组3里的PDSCH对应的HARQ码本可以如表7所示：
表7
Figure PCTCN2019085386-appb-000007
在PUCCH 1上的多个组的连续反馈中，通过从DAI计数为0开始且多个组对应的DAI计数连续，可以保证对于UE正确接收到的PDSCH对应的码本位置，基站和UE的理解都是一致的，进而实现HARQ码本的传输。
如果一个上行资源上反馈至少两个组的HARQ码本，另一种情况是不限定基站只能触发连续的多个组的HARQ码本反馈，好处是中间组中包括的HARQ进程对应的HARQ信息可以尽早被释放以用于基站下行调度。
图9是本申请实施例的信道组、DAI和反馈组的位置关系的另一示意性框图。
DAI计数连续的多个信道组，且所述多个信道组中的至少两个信道组为被触发反馈的DAI计数不连续的信道组的情况下，下面结合图9对所述第一HARQ码本进行详细说明。
请参见图9，PUCCH 2上反馈组0和组2，PUCCH 3上反馈组1和组3，UE可以根据基站调度的顺序准备码本。UE在准备该PUCCH资源上传输的HARQ码本时，无论排序的第一个组内的第一个PDSCH对应的DAI是什么，UE都从DAI为0开始准备。具体地，UE根据DAI的顺序准备HARQ码本，对于中间未被触发发送HARQ信息的组，需要补充占位信息。该占位方式可以保证对于UE正确接收到的PDSCH对应的码本位置，使得基站和UE的理解保持一致。
可选地，占位信息为预设信息。
可选地，占位信息是NACK信息。
可选地，占位信息不是NACK信息等具有具体含义的信息，占位信息所对应的位置也不能正常存放码本，例如可以理解为留空，即不用于存放码本信息。
对于PUCCH 2上传输的HARQ码本中包括的组0和组2里的PDSCH对应的HARQ码本可以如表8所示：

其中，组的个数可以是基站配置的或预定义的。例如，基站配置的组的个数为4。
可选地，所述第一DCI可以包括一个有效的HARQ时序指示信息，用于确定上述第一上行资源。
可选地，所述终端设备接收第一下行控制信息DCI，所述第一DCI用于调度第一PDSCH，所述第一PDSCH属于第一信道组，所述第一DCI中包括第一指示信息，所述第一指示信息用于指示所述多个信道组中的信道组是否触发反馈。可选地，所述第一指示信息中包括的所述多个信道组的触发反馈信息是按照组编号从小到大或组编号从大到小的顺序排列的。即如果一个上行资源上反馈至少两个组的HARQ码本，基站在触发UE进行该组的HARQ信息反馈时，可以按组编号从小到大(或组编号从大到小或基站指定)的顺序进行触发反馈。
在一种实现方式中，所述第一指示信息用于指示所述多个信道组中除所述第一信道组外的其他信道组是否触发反馈。例如，所述第一DCI中的HARQ时序指示信息用于确定所述第一上行资源，所述第一指示信息用于指示所述多个信道组中除所述第一信道组外的其他信道组是否在所述第一上行资源触发反馈。
举例来说，假设第一PDSCH属于信道组#0，基站配置有4个组，其包括信道组#0，则：
可选地，信道组#0对应的HARQ信息通过有效的HARQ时序指示信息指示的第一上行资源反馈。
可选地，除信道组#0外的其他被触发的信道组对应的HARQ信息也通过该第一上行资源反馈。
可选地，所述第一指示信息包括3比特的组触发信息，所述3比特的组触发信息分别用于指示除信道组#0外的其他信道组是否被触发进行HARQ信息反馈。可选地，所述3比特的组触发信息可以按照除该第一PDSCH所属的组(即信道组#0)外的其他组的编号从小到大排序。例如，100表示组1被触发，010表示组2被触发，001表示组3被触发。又例如，101表示组1和组3被触发。
可选地，被触发反馈的信道组对应的HARQ码本排列顺序可以按调度的顺序进行准备。例如，被触发反馈的信道组包括#0、#1、#2，基站调度的组的顺序(即DAI的顺序)为#1、#0、#2，那么UE根据#1、#0、#2的顺序来准备HARQ码本。
在另一种实现方式中，所述第一指示信息用于指示所述多个信道组中的每个信道组是否触发反馈。例如，所述第一DCI中的HARQ时序指示信息用于确定所述第一上行资源，所述第一指示信息用于指示所述多个信道组中的每个信道组在所述第一上行资源上是否触发反馈。
举例来说，假设第一PDSCH属于信道组#0，基站配置有4个组，其包括信道组#0，则：
可选地，所述第一DCI中包括一个有效的HARQ时序指示信息，且所述第一DCI中还包括4比特的组触发信息，该4比特用于指示该4个组是否被触发进行HARQ信息反馈。
可选地，该HARQ时序指示信息的取值只在信道组#0被触发时才有意义。
可选地，该HARQ时序指示信息用于指示被触发的信道组对应的HARQ信息反馈使用的第一上行资源。
可选地，信道组#0可以被触发反馈，也可以不被触发反馈。
可选地，所述第一DCI中的HARQ时序指示信息具体用于指示所述第一PDSCH对应的HARQ信息暂不反馈，所述第一指示信息无效。例如，所述终端设备忽略所述第一指示信息。可选地，所述第一DCI中的HARQ时序指示信息具体用于指示所述第一PDSCH对应的HARQ信息暂不反馈时，所述第一指示信息可以用于其它用途，例如作为其它信息使用。
可选地，所述终端设备接收所述第二DCI，所述第二DCI用于调度第二PDSCH，所述第二DCI中的HARQ时序指示信息用于指示所述第二PDSCH对应的HARQ信息暂不反馈，所述第二DCI中不包括用于指示所述多个信道组中的信道组是否触发反馈的指示信息。
举例来说，假设第二PDSCH属于信道组#0，基站配置有4个组，其包括信道组#0，则：
可选地，所述第二DCI中可以不包括触发所述至少一个组的HARQ信息反馈的指示信息(即前述的3比特或4比特)，或者，该第二DCI中包括触发所述至少一个组的HARQ信息反馈的指示信息指示不触发反馈，或者，该第二DCI中包括触发所述至少一个组的HARQ信息反馈的指示信息取值无意义。或者，该第二DCI中包括触发所述至少一个组的HARQ信息反馈的指示信息取值可以用于其它用途，例如作为其它信息使用。
可选地，所述终端设备接收第三DCI，所述第三DCI不用于调度PDSCH，所述第三DCI中包括第二指示信息，所述第二指示信息用于指示所述多个信道组中的信道组是否触发反馈。可选地，所述第二指示信息中包括的所述多个信道组的触发反馈信息是按照组编号从小到大或组编号从大到小的顺序排列的。可选地，所述第三DCI中还包括用于确定所述第一上行资源的HARQ时序指示信息，所述第二指示信息用于指示所述多个信道组中的每个信道组是否在所述第一上行资源上反馈。
举例来说，假设基站配置有4个组，所述第三DCI不用于调度PDSCH(例如，所述第三DCI不用于调度该4个组内的PDSCH)，则：
所述第三DCI中可以包括4比特，所述4比特用于指示该4个组是否被触发进行HARQ信息反馈的指示信息。
可选地，所述第三DCI中包括一个有效的HARQ时序指示信息，该HARQ时序指示信息用于指示被触发的信道组对应的HARQ信息反馈使用的上行资源。即所述第二指示信息用于指示所述多个信道组中的每个信道组是否在所述第一上行资源上反馈。
UE在准备HARQ码本时，可以根据DAI的顺序或基站调度的顺序或调度的组的顺序来准备。由此可以保证对于UE正确接收到的PDSCH对应的码本位置，使得基站和UE的理解都是一致的。
图10是本申请实施例的信道组、DAI和反馈组的位置关系的另一示意性框图。
结合图10来说，假设基站配置4个组，在触发HARQ反馈时，如果触发信令不调度PDSCH，那么触发PUCCH2上反馈HARQ的组编号的信令为1010(即触发PUCCH2上反馈组0和组2)，触发PUCCH3上反馈HARQ的组编号的信令为1011(即触发PUCCH2上反馈组0、组2和组3)。
如果触发PUCCH2上反馈HARQ的信令是调度PDSCH 8的DCI指示的，那么触发信令为100(即默认触发PDSCH 8所属的组2)；如果触发PUCCH3上反馈HARQ的信令是调度PDSCH 10的DCI指示的，那么触发信令为101(即默认触发PDSCH 10所属的组3)。
其中，PUCCH 2上UE根据组#0、#2的顺序来准备HARQ码本；PUCCH 3上UE根据组#0、#2、#3的顺序来准备HARQ码本。
