Description

用于传输反馈信息的方法、终端设备和网络设备 技术领域
本申请涉及通信领域，尤其涉及用于传输反馈信息的方法、终端设备和网络设备。
背景技术
对于新无线(New Radio，NR)系统中版本16(Rel-16)的NR基于免授权频谱的访问(NR-based Access to Unlicensed Spectrum，NR-U)，其支持在下行控制信令(Downlink control information，DCI)中引入一个混合自动重传请求(hybrid automatic repeat request，HARQ)反馈时序(HARQ-timing)取值为无穷大的情况，该取值表示该DCI调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)对应的确认/非确认(ACK/NACK)反馈信息传输时间和资源暂时无法确定。
基站发送触发信令，终端设备基于触发信令确定传输之前的PDSCH对应的ACK/NACK。为了保证终端设备与基站对触发的反馈信息的理解一致，很多公司提出了在触发信令中指示PDSCH组信息，终端根据该组信息确定反馈信息码本包括哪些PDSCH对应的反馈信息。
因此，终端设备首先要确定每个接收到的PDSCH对应的组信息。例如，当调度PDSCH的DCI中的HARQ反馈时序的信息域取值为特定取值时，该信息域可以用于指示下行传输组的信息。
该方法的最大优势在于不增加DCI开销即可指示下行传输组信息。但当调度PDSCH的DCI中的HARQ反馈时序的信息域取值不是特定取值时，该PDSCH则无对应的组信息。基于下行资源组的触发信令则无法触发终端发送该PDSCH对应的反馈信息，降低了下行传输效率。
发明内容
本申请实施例提供一种用于传输反馈信息的方法、终端设备和网络设备，能够保证下行传输效率。
第一方面，提供了一种用于传输反馈信息的方法，包括：终端设备接收触发信令，该触发信令用于触发该终端设备发送反馈信息；该终端设备根据该触发信令，确定采用第一反馈模式或者第二反馈模式发送反馈信息码本。其中，该第一反馈模式为：该反馈信息码本包括该触发信令指示的至少一个下行传输信道或下行传输资源对应的反馈信息；该第二反馈模式为：该反馈信息码本为全码本。
第二方面，提供了一种用于传输反馈信息的方法，包括：网络设备发送触发信令，该触发信令用于触发该终端设备发送反馈信息码本，该反馈信息码本是采用第一反馈模式或第二反馈模式发送的。其中，该第一反馈模式为：该反馈信息码本包括该触发信令指示的至少一个下行传输信道或下行传输资源的反馈信息；该第二反馈模式为：该反馈信息码本为全码本。

第六方面，提供了一种网络设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述第二方面或其 各实现方式中的方法。
第七方面，提供了一种芯片，用于实现上述第一方面至第二方面中的任一方面或其各实现方式中的方法。具体地，该芯片包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该芯片的设备执行如上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第八方面，提供了一种计算机可读存储介质，用于存储计算机程序，该计算机程序使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第九方面，提供了一种计算机程序产品，包括计算机程序指令，该计算机程序指令使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第十方面，提供了一种计算机程序，当其在计算机上运行时，使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
通过上述技术方案，终端设备通过触发信令确定采用哪一种反馈模式传输反馈信息码本，这样能够保证在下行控制信令中不额外增加下行传输信道组/资源组指示信息的情况下，实现基于下行传输信道组/资源组的触发反馈信息。当所有下行传输信道/资源都有对应的组信息时，终端设备可以根据触发信令中指示的组信息确定反馈信息码本，可避免反馈码本中冗余信息的存在。当某个下行传输信道/资源没有组信息时，可动态指示终端设备使用全码本的反馈方式传输反馈信息，保证所有下行传输信道/资源对应的反馈信息都能够被传输，从而保证下行传输效率。

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：通用分组无线业务(General Packet Radio Service，GPRS)、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)、通信系统或5G系统等。
示例性的，本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。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，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移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的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。作为在此使用的“终端设备”包括但不限于经由有线线路连接，如经由公共交换电话网络(Public Switched Telephone Networks，PSTN)、数字用户线路(Digital Subscriber Line，DSL)、数字电缆、直接电缆连接；和/或另一数据连接/网络；和/或经由无线接口，如，针对蜂窝网络、无线局域网(Wireless Local Area Network，WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器；和/或另一终端设备的被设置成接收/发送通信信号的装置；和/或物联网(Internet of Things，IoT)设备。被设置成通过无线接口通信的终端设备可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、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。接入终端可以是蜂窝电话、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、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
可选地，终端设备120之间可以进行终端直连(Device to Device，D2D)通信。
可选地，5G系统或5G网络还可以称为新无线(New Radio，NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端设备，可选地，该通信系统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，本申请实施例对此不做限定。
可选地，该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体，本申请实施例对此不作限定。
应理解，本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例，通信设备可包括具有通信功能的网络设备110和终端设备120，网络设备110和终端设备120可以为上文所述的具体设备，此处不再赘述；通信设备还可包括通信系统100中的其他设备，例如网络控制器、移动管理实体等其他网络实体，本申请实施例中对此不做限定。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
免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。为了让使用免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免授权频谱必须满足的法规要求。例如，在一些地区，通信设备遵循“先听后说”原则，即通信设备在免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；如果通信设备在免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，通信设备使用免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 Occupation Time，MCOT)。
随着无线通信技术的发展，LTE系统和NR系统都会考虑在免授权频谱上布网，以利用免授权频谱来进行数据业务的传输。
在NR版本15(Rel-15)中，支持动态确定HARQ反馈时序(HARQ-timing)。终端设备首先确定预配置HARQ timing集合，基站通过下行控制信息(Downlink control information，DCI)指示HARQ timing集合中的一个数值为k，若该DCI调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)在时隙(slot)n中传输，则其对应的确认/非确认(ACK/NACK)信息在slot n+k中传输。其中，预配置HARQ timing集合最多可以包括8个值，对于不同DCI的个数(format)，该8个值可以不同，例如，对于DCI format 1_0，该集合由协议约定，对于DCI format 1_1，该集合可以由基站配置。
另外，NR Rel-15系统中还支持ACK/NACK复用传输，即多个PDSCH对应的ACK/NACK信息通过一个信道传输。对于ACK/NACK复用传输，进一步地支持两种ACK/NACK信息生成方式：半静态ACK/NACK码本(semi-static HARQ-ACK codebook)和动态ACK/NACK码本(dynamic HARQ-ACK codebook)。
其中，半静态ACK/NACK码本是基于预配置的反馈时序集合中的元素确定的，由于反馈时序集合是协议约定或高层半静态配置的，因此ACK/NACK码本中包含的ACK/NACK比特数量是不会根据实际的调度情况改变的。此方案的优势在于基站与UE对反馈信息的数量及映射关系不会有理解歧义。但缺点在于反馈开销较大，即便只调度了少量PDSCH仍然要传输一个完整的ACK/NACK码本，其中可能包含大量的冗余信息。例如，如图2所示，对于单载波单码字传输情况下，假设DCI中HARQ timing集合指示的数值为8，则预配置反馈时序集合中元素个数为8，该预配置反馈时序集合为{1,2,3,4,5,6,7,8}，则ACK/NACK比特数目也为8比特。但实际中，如图2所示，仅传输了两个PDSCH，也就是存在6比特的冗余信息。
而动态ACK/NACK码本主要解决反馈开销问题，即在反馈时间集合对应的下行slot内，根据实际调度的PDSCH数量确定ACK/NACK信息数量。具体的调度PDSCH传输的DCI中引入下行分配索引(Downlink assignment index，DAI)信息域，用以指示截止到当前调度的PDSCH为止已经调度的PDSCH总数量。以图2为例，对于单载波单码字传输情况下，终端设备接收PDSCH 1和PDSCH2共两个PDSCH，此时终端设备只需要反馈2比特信息。该方法的缺点便是当终端设备未收到基站发送的部分PDSCH(例如图2最后的PDSCH 2)时，存在基站与UE对实际调度的PDSCH数量理解不一致的问题，从而造成对反馈信息的数量理解不一致。
针对Rel-16的NR-U，其支持在下行控制信令中引入一个HARQ timing取值为无穷大的情况，该取值表示该DCI调度的PDSCH对应的ACK/NACK反馈信息传输时间和资源暂时无法确定。后续基站发送触发信令，终端设备基于触发信令确定传输之前的PDSCH对应的ACK/NACK。为了保证终端设备与基站对触发的反馈信息的理解一致，很多公司提出了在触发信令中指示PDSCH组信息，终端设备根据该组信息确定反馈信息码本包括哪些PDSCH对应的反馈信息。
因此，终端首先要确定每个接收到的PDSCH对应的组信息。例如，当调度PDSCH的DCI中的HARQ反馈时序的信息域取值为特定取值时，该信息域可以用于指示下行传输组的信息。该方法的最大优势在于不增加DCI开销即可指示下行传输组信息。但当调度PDSCH的DCI中的HARQ反馈时序的信息域取值不是特定取值时，该PDSCH则无对应的组信息。基于下行资源组的触发信令则无法触发终端设备发送该PDSCH对应的反馈信息，降低了下行传输效率。
因此，本申请实施例提供了一种用于传输反馈信息的方法，终端设备基于触发信令的指示，在多种反馈模式中选择一种反馈模式来确定反馈信息码本，能够有效提高传输 效率。
图3为本申请实施例提供的一种用于传输反馈信息的方法200的示意性流程图。该方法200可以由终端设备执行例如，该终端设备可以为如图1所示的终端设备120。如图3所示，该方法200包括：S210，终端设备接收触发信令，该触发信令用于触发该终端设备发送反馈信息；S220，该终端设备根据该触发信令，确定采用第一反馈模式或者第二反馈模式发送反馈信息码本，其中，该第一反馈模式确定反馈信息码本的方式与该第二反馈模式确定反馈信息码本的方式不同。
具体地，该第一反馈模式为：该反馈信息码本包括该触发信令指示的至少一个下行传输信道或下行传输资源对应的反馈信息。也就是，该终端设备可以根据该触发信令，确定至少一个下行传输信道或下行传输资源，进而确定该反馈信息码本。
可选的，在该第一反馈模式中，该触发信令可以用于指示至少一个下行传输信道组或下行传输资源组，该至少一个下行传输信道组或下行传输资源组包括该至少一个下行传输信道或下行传输资源，每个下行传输信道组或下行传输资源组中可以包括一个或者多个下行传输信道或下行传输资源。
可选的，在该第一反馈模式中，若触发信令用于指示至少一个下行传输信道组或下行传输资源组，则在反馈信息码本中，该至少一个下行传输信道或下行传输资源对应的反馈信息可以按照该至少一个下行传输信道组或下行传输资源组的编号顺序排列，而不必按照接收顺序排列。
在本申请实施例中，该第二反馈模式为：该反馈信息码本为全码本。可选的，该终端设备可以确定能够支持的HARQ进程的最大数量，再根据支持的HARQ进程的最大数量，确定该反馈信息码本，例如，该反馈信息码本中可以包括全部能够支持的HARQ进程对应的反馈信息。
可选的，该终端设备还可以根据网络设备的配置，确定HARQ进程的最大数量，例如，终端设备接收网络设备发送的配置信息，根据该配置信息确定HARQ进程的最大数量。该终端设备再根据网络设备配置的HARQ进程的最大数量，确定该反馈信息码本，例如，该反馈信息码本可以包括全部网络设备配置的HARQ进程对应的反馈信息。
应理解，在该第二反馈模式中，若终端设备按照能够支持的HARQ进程确定反馈信息码本，或者按照网络设备配置的HARQ进程确定反馈信息码本，则在确定的反馈信息码本中的反馈信息都可以按照HARQ的进程的编号的顺序进行排列，而不必按照接收顺序或其他顺序排列，但本申请实施例并不限于此。
可选的，在第二反馈模式中，该终端设备还可以根据支持的下行传输信道组或下行传输资源组的最大数量，确定该反馈信息码本。具体地，该终端设备可以确定能够支持的下行传输信道组或下行传输资源组的数量，以及每个下行传输信道组或下行传输资源组中包括的下行传输信道或下行传输资源的个数，进而确定该终端设备能够支持的下行传输信道或下行传输资源的个数，则终端设备可以确定该反馈信息码本中包括全部能够支持的下行传输信道组或下行传输资源组对应的反馈信息，例如，包括能够支持的全部下行传输信道或下行传输资源对应的反馈信息。
应理解，在该第二反馈模式中，若终端设备按照支持的下行传输信道组或下行传输资源组的最大数量，确定该反馈信息码本，则该确定的反馈信息码本中的反馈信息的顺序可以按照下行传输信道组或下行传输资源组的编号进行排列，而不必按照接收顺序或其他顺序排列，但本申请实施例并不限于此。
应理解，本申请实施例可以应用于免授权频谱，或者，也可以用于授权频谱，本申请实施例并不限于此。
在本申请实施例中，在S210之前，该方法200还可以包括：终端设备接收网络设备发送的下行传输信道或下行传输资源，其中，该下行传输信道可以包括下行物理共享信道和/或下行物理控制信道。具体地，网络设备向终端设备发送至少一个下行传输信道或 者至少一个下行传输资源，终端设备可能接收到该至少一个下行传输信道中的部分或者全部下行传输信道的信息，或者全部未接收到；或者，终端设备可能接收到至少一个下行传输资源中部分或者全部下行传输资源中的信息，或者全部下行传输资源中的信息均未接收到。
因此，在S210中，终端设备接收触发信令，例如，该触发信令可以是图1中的网络设备110发送给终端120的，该触发信令用于触发终端设备发送反馈信息，该反馈信息为终端设备接收到的下行传输信道或者下行传输资源对应的反馈信息。
在S220中，该终端设备根据该触发信令，确定采用第一反馈模式或者第二反馈模式发送反馈信息码本。具体地，该触发信令中可以包括第一信息域，若该第一信息域为第一预设值，该终端设备选择采用该采用第一反馈模式确定该反馈信息码本；或者，若该第一信息域为第二预设值，该终端设备选择采用该采用第二反馈模式确定该反馈信息码本。其中，该第一预设值或者第二预设值均可以表示一个或者多个数值，本申请实施例并不限于此。
下面将结合具体地实施例，针对第一信息域的不同含义，详细描述终端设备根据触发信令确定反馈模式的方法。
可选的，作为第一个实施例，若该第一信息域为该第一预设值，终端设备可以根据第一信息域既确定采用第一反馈模式，又可以确定反馈信息码本中的反馈信息，例如，该第一预设值可以用于指示该至少一个下行传输信道组或下行传输资源组的信息。
例如，假设终端设备最大支持16个HARQ进程，同时终端设备最大支持4个下行传输信道组，其中，每个下行传输信道组可以包括一个或者多个下行传输信道。对应于终端设备最大支持的4个下行传输信道组，其中，每个下行传输信道组可以对应一个或者多个比特表示。这里假设每个下行传输信道组对应使用一比特表示，则该第一信息域可以由4比特信息组成，例如，该第一信息域可以表示为{b1，b2，b3，b4}，采用bitmap的方式指示4个下行传输信道组。
对应于该第一信息域为第一预设值的情况，这里假设当该{b1，b2，b3，b4}至少有一个比特位置1，但{b1，b2，b3，b4}不全为1时，即为第一预设值。此时，该终端设备确定采用第一反馈模式。具体地，终端设备还可以根据{b1，b2，b3，b4}的具体取值，确定需要反馈哪些下行传输信道组的反馈信息。例如，若{b1，b2，b3，b4}中的bi为1，可以用于表示需要反馈该bi对应的第i组下行传输信道组的反馈信息，例如，该反馈信息可以为ACK/NACK信息，i可以取1至4中任意值。
例如，图4示出了根据本申请实施例的下行传输信道和反馈信息的示意图，如图4所示，假设触发信令中的第一信息域为{1,1,0,0}，则终端设备确定采用第一反馈模式，对应的，终端设备还可以根据该第一信息域确定反馈信息码本包括第一组下行传输信道组和第二组下行传输信道组的反馈信息。
应理解，终端设备可以通过多种方式对下行传输信道进行分组，例如，下行传输信道的分组情况可能如图4所示；并且，对下行传输信道的分组原则可以与HARQ进程编号无关，每个下行传输信道组内的多个下行信道对应的HARQ进程号可以由网络设备动态分配的，结果可能是随机分布的，例如图5所示；或者，分组结果也可能与HARQ进程号相关。例如，第一组下行传输信道对应HARQ进程号为1至4，第二组下行传输信道对应HARQ进程号为2至8等，本申请实施例并不限于此。
另外，终端设备还可以通过多种方式确定该第一组下行传输信道组和第二组下行传输信道组的反馈信息。例如，假设终端设备接收的每个下行传输信道组中最多包括4个PDSCH，其中，第一组下行传输信道组、第二组下行传输信道组和第三组下行传输信道组实际包括的PDSCH的个数如图4所示，则终端设备确定的反馈信息码本可以为{b G1,1,b G1,2,b G1,3,b G1,4,b G2,1,b G2,2,b G2,3,0}，或者{b G1,1,b G1,2,b G1,3,b G1,4,b G2,1,b G2,2,b G2,3}，其中，b Gi,j表示下行传输信道组i中第j个PDSCH对应的ACK/NACK信息。或者，终端设备也 可以通过其他方式反馈第一组下行传输信道组和第二组下行传输信道组的反馈信息，本申请实施例并不限于此。
可选的，在该第一反馈模式中，反馈信息码本可以按照下行传输信道组的编号顺序排列对应的反馈信息，而不是按照下行传输信道的传输时间顺序排列反馈信息。如同4所示，虽然下行传输信道组1的传输时间在组2之后，但组1对应的ACK/NACK信息在反馈信息码本中排在组2对应的ACK/NACK信息之前，但本申请实施例并不限于此。
相反的，假设当{b1，b2，b3，b4}全为1时，表示第一信息域为第二预设值，则该终端设备确定采用第二反馈模式发送反馈信息，其中，该反馈信息为ACK/NACK信息。
例如，图5示出了根据本申请实施例的下行传输信道和反馈信息的另一示意图，如图5所示，假设第一信息域为{1,1,1,1}，则终端设备确定采用第二反馈模式，例如，终端设备可以确定反馈信息码本包括终端设备能够支持的全部16的HARQ进程对应的ACK/NACK信息，该反馈信息码本可以为{b p1,b p2,b p3,……,b p16}，其中，bpi表示进程i对应的ACK/NACK信息。可选的，bpi可以是一比特信息，或多比特信息。例如，当终端设备被配置一个PDSCH中最多承载2个传输块时，bpi可以对应包括2比特信息；当终端设备被配置一个PDSCH中最多包括N个编码块时，bpi可以对应包括N比特信息。
应理解，上述以下行传输信道为例进行说明，而对于下行传输资源同样适用。为了简洁，在此不再赘述。
其中，下行传输资源的分组方式与下行传输信道可以相同或者不同，例如，下行传输资源或者下行传输信道都可以根据信道占用时间(Channel Occupation Time，COT)进行分组。
具体地，以对下行传输资源进行分组为例，终端设备可以根据下行传输资源所在的COT，对下行传输资源进行分组。例如，终端设备可以将位于同一个COT的下行传输资源确定为属于同一个下行传输资源组；再例如，终端设备还可以将多个COT内的下行传输资源都确定为属于同一个下行传输资源组，本申请实施例并不限于此。
可选的，作为第二个实施例，该触发信令还可以包括第二信息域，若该第一信息域为该第一预设值，终端设备根据第一信息域确定采用第一反馈模式确定反馈信息码本，同时还可以根据该第二信息域确定该反馈信息码本中包括的该至少一个下行传输信道组或下行传输资源组的信息。
例如，这里仍然假设终端设备最大支持16个HARQ进程，同时终端设备最大支持4个下行传输信道组，其中，每个下行传输信道组可以包括一个或者多个下行传输信道。假设该第一信息域由1比特信息组成，表示为{b0}，该第一信息域可以用于指示第一反馈模式或第二反馈模式。
例如，对应于该第一信息域为第一预设值的情况，这里假设{b0}取值为0时即为第一预设值，则终端设备确定采用第一反馈模式。具体地，终端设备可以根据触发信令中的第二信息域确定反馈信息码本。
对于第二信息域，对应于终端设备最大支持的4个下行传输信道组，每个下行传输信道组可以对应一个或者多个比特表示。这里假设每个下行传输信道组对应使用一比特表示，则该第二信息域可以由4比特信息组成，例如，该第二信息域可以表示为{b1，b2，b3，b4}，采用bitmap的方式指示4个下行传输信道组。该终端根据{b1，b2，b3，b4}的指示，采用第一反馈模式发送反馈信息，例如，该反馈信息可以为ACK/NACK信息。其中，若{b1，b2，b3，b4}中的bi为1，可以用于表示需要反馈该bi对应的第i组下行传输信道组的ACK/NACK信息，i可以取1至4中任意值。
例如，图4示出了根据本申请实施例的下行传输信道和反馈信息的示意图，如图4所示，假设触发信令中的第二信息域为{1,1,0,0}，则终端设备确定反馈信息码本包括第一组下行传输信道组和第二组下行传输信道组的反馈信息。
应理解，与第一个实施例类似，终端设备同样可以通过多种方式对下行传输信道进 行分组，例如，下行传输信道的分组情况如图4所示；终端设备还可以通过多种方式确定该第一组下行传输信道组和第二组下行传输信道组的反馈信息，为了简洁，在此不再赘述。
相反的，对于该第一信息域为第二预设值的情况，这里假设{b0}取值为1时即为第二预设值，则终端设备确定采用第二反馈模式。具体地，终端设备可以按照第一个实施例中的方式，确定第二反馈模式对应的反馈信息码本，为了简洁，在此不再赘述。
应理解，对于上述的两个实施例中任意一个下行传输信道或者任意一个下行传输资源，这里以第一下行传输信道为例，若该第一下行传输信道的结束时刻至发送该反馈信息码本的起始时刻之间的时间间隔小于或者等于第一预设时间，该第一下行传输信道对应的反馈信息为NACK信息或占位信息；或者，以第一下行传输资源为例，若该第一下行传输资源的结束时刻至发送该反馈信息码本的起始时刻之间的时间间隔小于或者等于第一预设时间，该第一下行传输资源对应的反馈信息为NACK信息或占位信息。
例如，以图4中的第3组下行传输信道中的PDSCH1为例。无论采用第一反馈模式还是第二反馈模式，若需要反馈该第3组下行传输信道中的PDSCH 1，假设该第3组下行传输信道中的PDSCH 1的结束时刻至反馈信息码本对应的物理上行控制信道(Physical Uplink Control Channel，PUCCH)的起始时刻之间的时间间隔为T 31，且该T 31小于或者等于第一预设时间，例如如图4所示，T 31<第一预设时间，则该第3组下行传输信道中的PDSCH 1对应的反馈信息为NACK信息或占位信息。
另外，对于上述的两个实施例中任意一个下行传输信道或者任意一个下行传输资源，这里以第二下行传输信道为例，若该终端设备未接收到该第二下行传输信道，该第二下行传输信道对应的反馈信息为NACK信息或占位信息；或者，以第二下行传输资源为例，若该终端设备未在该第二下行传输资源内接收到下行传输，该第二下行传输资源对应的反馈信息为NACK信息或占位信息。
例如，以图4中的第2组下行传输信道中的PDSCH 3为例。无论采用第一反馈模式还是第二反馈模式，若需要反馈该第2组下行传输信道中的PDSCH 3，假设终端设备未接收到该第2组下行传输信道中的PDSCH 3，则该第3组下行传输信道中的PDSCH 1对应的反馈信息为NACK信息或占位信息。
由于上述的第一下行传输信道与第二下行传输信道都可能设置为NACK信息或占位信息，但第一下行传输信道与第二下行传输信道的情况不同，而对于网络设备侧无法判断该第一下行传输信道与第二下行传输信道分别属于哪一种情况，因此，终端设备不期望出现需要反馈第一下行传输信道的这种情况。同样的，终端设备也不期望反馈第一下行传输资源对应的情况。
应理解，对于本申请实施例中的任意一个HARQ进程而言，这里以第一HARQ进行为例，若该第一HARQ进程的结束时刻至发送该反馈信息码本的起始时刻之间的时间间隔小于或者等于第二预设时间，该第一HARQ进程对应的反馈信息为NACK信息或占位信息。
例如，以图5中的HARQ进程2为例，也就是以第3组下行传输信道中的PDSCH 1为例。若采用第二反馈模式，且需要反馈该HARQ进程2对应的下行传输信道的反馈信息。假设该HARQ进程2对应的下行传输信道的结束时刻至反馈信息码本对应的PUCCH的起始时刻之间的时间间隔为T 2，且该T 2小于或者等于第二预设时间，例如如图5所示，T 2<第二预设时间，则该HARQ进程2对应的下行传输信道对应的反馈信息为NACK信息或占位信息。
另外，对于本申请实施例中的任意一个HARQ进程而言，这里以第二HARQ进行为例，若该终端设备未接收到该第二HARQ进程，该第二HARQ进程对应的反馈信息为NACK信息或占位信息。例如，以图5中的HARQ进程12为例，也就是以图4中的第2组下行传输信道中的PDSCH 3为例。若采用第二反馈模式，且需要反馈该HARQ进程 12对应的下行传输信道的反馈信息。假设终端设备未接收到该HARQ进程12对应的下行传输信道，则该HARQ进程12对应的下行传输信道的反馈信息为NACK信息或占位信息。
由于上述的第一HARQ进程与第二HARQ进程都可能设置为NACK信息或占位信息，但第一HARQ进程与第二HARQ进程的情况不同，而对于网络设备侧无法判断该第一HARQ进程与第二HARQ进程分别属于哪一种情况，因此，终端设备不期望出现需要反馈第一HARQ进程的这种情况。
应理解，本申请实施例中的第一预设值和第二预设值可以根据实际应用进行设置，例如，可以根据下行传输信道或者下行传输资源的处理时延进行设置，本申请实施例并不限于此。
因此，本申请实施例用于传输反馈信息的方法，终端设备通过触发信令确定采用哪一种反馈模式传输反馈信息码本，这样能够保证在下行控制信令中不额外增加下行传输信道组/资源组指示信息的情况下，实现基于下行传输信道组/资源组的触发反馈信息。当所有下行传输信道/资源都有对应的组信息时，终端设备可以根据触发信令中指示的组信息确定反馈信息码本，可避免反馈码本中冗余信息的存在。当某个下行传输信道/资源没有组信息时，可动态指示终端设备使用全码本的反馈方式传输反馈信息，保证所有下行传输信道/资源对应的反馈信息都能够被传输，从而保证下行传输效率。
