Description

反馈信息的传输方法及通信装置
本申请要求于2019年08月16日提交国家知识产权局、申请号为201910759305.3、申请名称为“反馈信息的传输方法及通信装置”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
本申请涉及通信领域，尤其涉及一种反馈信息的传输方法及通信装置。
背景技术
目前，半静态(semi-persistent)混合自动重传请求(hybrid automatic repeat request，HARQ)机制中，通常为同一个数据块，如一个传输块(transmission block，TB)的多次重传设置1个反馈比特，以指示该数据块是否传输成功，其中，多次重传可以由一个下行控制信令(downlink control information，DCI)调度。示例性地，网络设备可以为终端设备配置多个候选资源，如用于指示PDSCH时域位置的R集合中多个r各自对应的物理下行共享信道(physical downlink shared channel，PDSCH)，以及多个候选资源中的每个候选资源均会占用不同的时间单元，比如时隙(slot)，通过K1集合中多种取值配置，上述多个候选资源会对应同一个物理上行控制信道(physical uplink control channel，PUCCH)用于承载相应的HARQ-ACK比特。网络设备根据待发送的数据块大小和数量，选择一个或多个候选资源向终端设备发送数据块。若终端设备在选择的候选资源上成功接收到数据块，则在该候选资源对应反馈资源上向网络设备发送肯定确认(acknowledgment，ACK)，否则发送否定确认(negative acknowledgment，NACK)。当然，对于空闲的候选资源，即不存在数据传输的候选资源，终端设备也需要向网络设备发送NACK。
容易理解，在多个候选资源中任意两个候选资源之间存在冲突因而不会同时调用的情况下，如多个候选资源在时域上存在交叠，可以为该多个候选资源只预留1个反馈比特，即存在冲突的多个候选资源可以对应同一个反馈比特，以减少反馈信息的数据量，降低反馈资源开销，提高通信效率。然而，判断多个候选资源中任意两个候选资源之间是否冲突是基于网络设备下发的候选资源的配置信息完成的，而该配置信息指示的候选资源只是针对单次传输的。也就是说，判断多个候选资源中任意两个候选资源之间是否冲突并没有考虑单次传输不冲突，但多次重传冲突的情况，从而导致在多次重传场景下，仍然可能存在多个候选资源对应的反馈信息冗余和资源浪费问题。
发明内容
本申请实施例提供一种反馈信息的传输方法及通信装置，能够解决当重传次数大于1时，即使多个候选资源相互冲突不可能同时调用，也需要为所有候选资源分别预留反馈信息，从而导致反馈信息冗余和资源浪费的问题，能够提高通信效率。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种反馈信息的传输方法。该方法包括：终端设备接收来自网络 设备的至少两个候选资源各自对应的重复因子的指示信息和配置信息。其中，至少两个候选资源各自对应的重复因子中存在取值大于1的重复因子。然后，终端设备根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息。
本申请提供的反馈信息的传输方法，能够根据至少两个候选资源各自对应的重复因子的指示信息和配置信息，确定至少两个候选资源对应的反馈信息，其中，至少两个候选资源各自对应的重复因子中存在取值大于1的重复因子。也就是说，终端设备可以判断在多次重传场景下，至少两个候选资源之间是否冲突，并根据冲突判断结果为至少两个候选资源预留反馈信息，以降低实际需要的反馈信息的数据量，从而降低反馈资源开销，提高通信效率。
在一种可能的设计方法中，上述终端设备根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息，可以包括:终端设备根据重复因子和配置信息，确定至少两个候选资源各自对应的第一结束符号的位置。然后，终端设备根据至少两个候选资源各自对应的第一结束符号的位置，确定第二结束符号的位置；其中，第二结束符号为至少两个候选资源各自对应的第一结束符号中符号编号最小的符号。之后，终端设备根据第二结束符号的位置，以及至少两个候选资源中，除第二结束符号对应的候选资源之外的其他候选资源占用的第一个符号的位置，确定第一传输时机；其中，第一传输时机对应一个或多个候选资源。最后，终端设备确定第一传输时机对应的反馈信息。其中，当候选资源为PDSCH时，传输时机可以为PDSCH时机(PDSCH occasion)。
示例性的，每个PDSCH时机可能对应一个或者多个反馈信息比特，对应多个反馈信息比特的情况可能为，一个TB被划分为多个码块(code block，CB)，每个码块对应一个反馈信息比特，从而可以支持仅重传该TB中的部分码块节省资源开销；或者为，一个TB被划分为多个码字(codeword，CW)，每个码字对应一个反馈信息比特，从而可以支持仅重传该TB中的部分码字节省资源开销。
可选地，上述至少两个候选资源中任一候选资源对应的第一结束符号可通过如下任一方式确定：若任一候选资源跨多个时间单元，则任一候选资源对应的第一结束符号为：任一候选资源在多个时间单元中的每个时间单元占用的最后一个符号中符号编号最小的符号，或者，任一候选资源在多个时间单元中占用的最后一个符号。或者，可选地，若任一候选资源只包括第一时间单元，则任一候选资源对应的第一结束符号为：任一候选资源在第一时间单元中占用的最后一个符号。
示例性地，上述至少两个候选资源包括第一候选资源和第二候选资源；第二结束符号为第一候选资源对应的第一结束符号。相应地，上述终端设备根据第二结束符号的位置，以及至少两个候选资源中，除第二结束符号对应的候选资源之外的其他候选资源占用的第一个符号的位置，确定第一传输时机，可以包括：若第一候选资源和第二候选资源满足第一条件，则终端设备将第一候选资源和第二候选资源确定为第一传输时机。其中，第一条件可以包括：第二候选资源在第二时间单元上占用的第一个符号的符号编号小于或等于第二结束符号的符号编号的符号。其中，第二时间单元为根据第二候选资源对应的重复因子的指示信息和配置信息确定的最后一个时间单元。

示例性地，至少两个候选资源可以包括第一候选资源和第二候选资源；第二起始符号为第一候选资源对应的第一起始符号。相应地，上述终端设备根据第二起始符号的位置，以及至少两个候选资源中，除第二起始符号对应的候选资源之外的其他候选资源占用的最后一个符号的位置，确定第一传输时机，可以包括：若第一候选资源和第二候选资源满足第二条件，则终端设备将第一候选资源和第二候选资源确定为第一传输时机。其中，第二条件可以包括：第二候选资源在第二时间单元上占用的最后一个符号的符号编号大于或等于第二起始符号的符号编号的符号。其中，第二时间单元为根据第二候选资源对应的重复因子的指示信息和配置信息确定的最后一个时间单元。
容易理解，上述第一传输时机对应的多个候选资源中任意两个候选资源之间在时域上存在交叠。示例性地，多个候选资源中的每个候选资源均可以对应一个或者多个传输时机，且一个候选资源对应的多个传输时机中的每个传输时机可以对应不同的时间间隔，也就是K1集合中的一个值。其中，时间间隔为承载反馈信息的时间单元与多个候选资源占用的最后一个时间单元之间间隔的时间单元数量。在同一个时间间隔的情况下，第一传输时机对应的多个候选资源中任意两个候选资源之间存在交叠。
在一种可能的设计方法中，若配置了多于两个候选资源，可能需要多次执行上述操作。示例性的，当终端设备经过上述一轮操作，将第一候选资源和第二候选资源确定为第一传输时机之后，候选资源集合中除去第一候选资源和第二候选资源后还包括第三候选资源和第四候选资源。进一步的，终端设备还可以根据第三候选资源和第四候选资源各自的第一结束符号位置，确定第三结束符号位置，第三结束符号位置为第三候选资源和第四候选资源各自的第一结束符号中符号编号最小的第一结束符号，然后根据第三结束符号确定第二传输时机。以此类推，直到上述至少两个候选资源中的所有候选资源均对应了一个传输时机为止。

本申请实施例中部分场景以图1所示的通信系统中的场景为例进行说明。应当指出的是，本申请实施例中的方案还可以应用于其他移动通信系统中，相应的名称也可以用其他移动通信系统中的对应功能的名称进行替代。
为便于理解本申请实施例，首先以图1中示出的通信系统为例详细说明适用于本申请实施例的通信系统。图1为本申请实施例提供的反馈信息的传输方法所适用的一种通信系统的架构示意图。如图1所示，该通信系统包括网络设备，以及一个或多个终端设备，如第一终端设备和第二终端设备。其中，网络设备，用于向终端设备发送至少两个候选资源各自对应的重复因子的指示信息和配置信息，以及根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息。相应地，终端设备，用于接收来自网络设备的至少两个候选资源各自对应的重复因子的指示信息和配置信息，以及根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息。其中，至少两个候选资源各自对应的重复因子中存在取值大于1的重复因子。基于该方案，终端设备和网络设备均能够根据至少两个候选资源各自对应的重复因子的指示信息和配置信息，确定至少两个候选资源对应的反馈信息。也就是说，终端设备和网络设备可以判断在多次重传场景下，至少两个候选资源之间是否冲突，并根据冲突判断结果为至少两个候选资源预留反馈信息，以降低实际需要的反馈信息的数据量，从而降低反馈资源开销，提高通信效率。
需要说明的是，图1中所示的网络设备和终端设备还可以执行其他功能。例如，网络设备可以根据待发送的数据包的大小、数量和重传次数，从上述多个候选资源中调度实际用于数据传输的候选资源上，在下行链路(downlink，DL)上向终端设备发送数据包。相应地，终端设备也可以根据待发送的数据包的大小、数量和重传次数，从上述多个候选资源中选择实际用于数据传输的候选资源上，在DL上接收网络设备发送的上述数据包。以及，在终端设备接收网络设备发送的上述数据包之后，终端设备还需要在与实际调度的候选资源对应的反馈资源上，在上行链路(uplink，UL)上向网络设备发送在实际调度的候选资源上接收的数据包对应的反馈信息。相应地，在网络设备向终端设备发送上述数据包之后，网络设备还需要在与实际调度的候选资源 对应的反馈资源上，在UL上接收终端设备发送的与在实际调度的候选资源上发送的数据包对应的反馈信息。
又例如，发送终端可以根据待发送的数据包的大小、数量和重传次数，从上述多个候选资源中调度实际用于数据传输的候选资源上，在侧行链路(sidelink，SL)上向接收终端发送数据包。相应地，接收终端也可以根据待发送的数据包的大小、数量和重传次数，从上述多个候选资源中选择实际用于数据传输的候选资源上，在SL上接收发送终端发送的上述数据包。以及，在接收终端接收发送终端发送的上述数据包之后，接收终端还需要在与实际调度的候选资源对应的反馈资源上，在该SL上向发送终端发送在实际调度的候选资源上接收的数据包对应的反馈信息。相应地，在发送终端向接收终端发送上述数据包之后，发送终端还需要在与实际调度的候选资源对应的反馈资源上，在该SL上接收接收终端发送的与在实际调度的候选资源上发送的数据包对应的反馈信息。其中，反馈信息用于指示在上述DL或SL上传输的数据包是否接收成功，具体可以包括如下一项或多项：ACK、NACK、信道质量信息(channel quality information，CQI)等。

下面结合图2对通信装置200的各个构成部件进行具体的介绍：
处理器201是通信装置200的控制中心，可以是一个处理器，也可以是多个处理元件的统称。例如，处理器201是一个或多个中央处理器(central processing unit，CPU)，也可以是特定集成电路(application specific integrated circuit，ASIC)，或者是被配置成实施本申请实施例的一个或多个集成电路，例如：一个或多个微处理器(digital signal processor，DSP)，或，一个或者多个现场可编程门阵列(field programmable gate array，FPGA)。
其中，处理器201可以通过运行或执行存储在存储器202内的软件程序，以及调用存储在存储器202内的数据，执行通信装置200的各种功能。
在具体的实现中，作为一种实施例，处理器201可以包括一个或多个中央处理单元(central processing unit，CPU)，例如图2中所示的CPU0和CPU1。
在具体实现中，作为一种实施例，通信装置200也可以包括多个处理器，例如图2中所示的处理器201和处理器204。这些处理器中的每一个可以是一个单核处理器(single-CPU)，也可以是一个多核处理器(multi-CPU)。这里的处理器可以指一个或多个通信设备、电路、和/或用于处理数据(例如计算机程序指令)的处理核。

下面将结合图3-图7对本申请实施例提供的反馈信息的传输方法进行具体阐述。
图3为本申请实施例提供的反馈信息的传输方法的流程示意图。该反馈信息的传输方法可以适用于上述通信系统中终端设备之间，或者终端设备与网络设备之间的通信。
如图3所示，该反馈信息的传输方法包括：
S301，网络设备向终端设备发送至少两个候选资源各自对应的重复因子的指示信息和配置信息。相应地，终端设备接收来自网络设备的至少两个候选资源各自对应的重复因子的指示信息和配置信息。其中，至少两个候选资源各自对应的重复因子中存在取值大于1的重复因子。
其中，上述重复因子可以是重复次数，也可以是与重传次数之间存在映射关系的其他信息，如重传次数索引、重传等级等，本申请实施例对此不作限定。应理解，重复因子指示了用于承载同一数据信息比特或者系统信息比特的物理时域资源的数量；每个物理时域资源均可以对应各自的解调参考信号(demodulation reference signal，DMRS)以用于数据解调；不同的物理时域资源可以占用不重叠的时域资源；不同的物理时域资源之间可以是连续的，也可以是不连续的；不同的物理时域资源也可以对应不同的准共址(quasi-co-location，QCL)接收假设；物理时域资源的位置基于重复因子和配置信息确定。此外，至少两个候选资源可以视为网络设备为终端设备配置的时域资源池。在一些通信系统中，如蜂窝网系统，网络设备可以根据待发送数据块的大小、数量，也可以根据业务需求或者调度需求从该资源池中选择候选资源，向终端设备发送待发送数据块。在另一些通信系统中，如车联网系统，发送终端可以根据待发送数据块的大小、数量，从该资源池中选择候选资源，向接收终端发送待发送数据块。下面以蜂窝网系统中的网络设备和终端设备为例，详细说明上述至少两个候选资源的配置方法。
在一种可能的设计方法中，上述S301，网络设备向终端设备发送至少两个候选资源各自对应的重复因子(repitition factor)和配置信息，可以包括：网络设备向终端设备发送下行控制信息DCI信令。相应地，上述S301，终端设备接收来自网络设备的至少两个候选资源各自对应的重复因子和配置信息，可以包括：终端设备接收来自网络设备的下行控制信息DCI信令。其中，DCI信令可以包括至少两个候选资源各自对应的重复因子。
或者，可选地，上述S301，网络设备向终端设备发送至少两个候选资源各自对应的重复因子和配置信息，可以包括：网络设备向终端设备发送无线资源控制RRC信令。相应地，上述S301，终端设备接收来自网络设备的至少两个候选资源各自对应的重复因子和配置信息，可以包括：终端设备接收来自网络设备的无线资源控制RRC信令。其中，RRC信令携带有至少两个候选资源各自对应的重复因子。
在本申请实施例中，可以通过在下行控制信息(downlink control information，DCI) 信令或无线资源控制(radio resource control，RRC)信令中，通过如下任一方式下发上述至少两个候选资源各自对应的重复因子和配置信息：增加重复因子字段(下文简称为指示方式1)、复用现有字段指示重复因子(下文简称为指示方式2)、增加信令(下文简称为指示方式3)。下面以蜂窝网中的物理下行共享信道(physical downlink shared channel，PDSCH)作为候选资源为例，说明上述三种指示方式。
对于指示方式1，可以在DCI信令中用于指示候选资源的时域位置的字段(field)，如起始和长度指示值(start and length indicator value，SLIV)字段中增加用于指示重复因子的字段。
示例性地，表1示出了指示方式1的示例一。如表1所示，每行包括PDSCH索引和PDSCH配置信息。其中，每个PDSCH索引对应表1中的一行PDSCH配置信息。该PDSCH配置信息可以包括：映射类型(类型A或类型B)字段和SLIV字段。该SLIV字段可以标记为{K0,S,L,N}。其中，K0为下发PDSCH配置信息的物理下行控制信道PDCCH与该PDSCH配置信息对应的PDSCH之间的时隙偏移量(slot offset)，S为PDSCH包含的首个符号在一个时隙中的符号偏移量(symbol offset)，也就是首个符号的符号编号，L为该PDSCH在一个时隙中的符号长度，也就是该PDSCH包含的符号数，N为重传次数。
例如，PDSCH索引＝0对应的{K0,S,L,N}的取值为{0,3,2,2}。也就是说，该PDSCH的第1次传输的时隙与下发PDSCH索引和PDSCH配置信息的DCI信令的时隙为同一时隙，且该第1次传输的起始符号为符号3(时隙中第一个符号编号为0)，结束符号为符号4，重传次数为2。在一些实施例中，假定该2次重传均在同一个时隙内，则第2次传输占用的符号为：符号5和符号6。在另一些实施例中，假定该2次传输分别位于不同时隙内，且第1次传输位于时隙i中，则第1次传输占用时隙i中的符号3和符号4，第2次传输占用时隙i+1中的符号3和符号4。上述各次传输均假定了各次传输之间的时域间隔l为0个符号，即连续传输，也可以假定各次传输之间的时域间隔l为n个符号，比如n＝1。在一些实施例中，假定该2次重传均在同一个时隙内，则第2次传输占用的符号为：符号6和符号7。
又例如，PDSCH索引＝1对应的{K0,S,L,N}的取值为{0,8,4,4}。也就是说，该PDSCH的第1次传输的时隙与下发PDSCH索引和PDSCH配置信息的DCI信令的时隙为同一时隙，且该第1次传输的起始符号为符号8，结束符号为符号11，重传次数为4。假定该4次传输分别位于不同时隙内，且第1次传输位于时隙i中，则第1次传输占用时隙i中的符号8至符号11，第2次传输占用时隙i+1中的符号8至符号11，第3次传输占用时隙i+2中的符号8至符号11，第4次传输占用时隙i+3中的符号8至符号11。在另一些实施例中，假定该4次传输中存在跨时隙传输，且第1次传输位于时隙i中，则第1次传输占用时隙i中的符号8至符号11，第2次传输占用时隙i中的符号12和符号13，以及时隙i+1中的符号0和符号1，第3次传输占用时隙i+1中的符号2至符号5，第4次传输占用时隙i+1中的符号6至符号9。其中，第2次传输为跨时隙传输，也可以将该跨时隙传输视为被时隙边界分割的2次传输。具体地，第1次传输占用时隙i中的符号8至符号11，第2次传输占用时隙i中的符号12和符号13，第3次传输占用时隙i+1中的符号0和符号1，第4次传输占用时隙i+1中的 符号2至符号5，第5次传输占用时隙i+1中的符号6至符号9。
需要说明的是，上述各次传输均假定了各次传输之间的时域间隔l为0个符号，即连续传输，也可以假定各次传输之间的时域间隔l为n个符号。例如，当n＝1时，在一些实施例中，假定该4次传输中存在可以跨时隙的传输，且第1次传输位于时隙i中，则第1次传输占用时隙i中的符号8至符号11，第2次传输占用时隙i中的符号13，以及时隙i+1中的符号0至符号2，第3次传输占用时隙i+1中的符号4至符号7，第4次传输占用时隙i+1中的符号9至符号12；或者，第2次传输占用时隙i+1中的符号0至符号3，第3次传输占用时隙i+1中的符号5至符号8，第4次传输占用时隙i+1中的符号10至符号13。

示例性地，表2示出了指示方式1的示例二。与表1不同，表2中的每一行中的SLIV字段为{K0,S,L,C}。其中，C为重传等级(category of transimmsion)或重传次数索引，该重传等级或重传次数索引与重传次数之间存在一一对应关系。表3为本申请实施例提供的重传等级与重传次数之间的映射关系表。如表3所示，重传次数可以为集合{1,2,4,8}中的一个取值。如表2所示，PDSCH索引＝0和PDSCH索引＝1对应的重传次数分别为2和4，各个PDSCH索引值对应的各次传输占用的时域位置与表1所示示例相同,此处不再赘述。

对于指示方式2，可以复用DCI信令中用于指示候选资源的空间相关性信息，如准共址(quasi co-location，QCL)信息的传输配置指示(transmission configuration indicator，TCI)字段的取值，间接指示重复因子。表6和表7各示出了一种利用TCI状态数与重复因子的映射关系的示例。如表6所示，TCI索引＝0的TCI配置共计有2个TCI状态，则其对应的重传次数＝2，TCI索引＝1的TCI配置共计有4个TCI状态，则其对应的重传次数＝4。如表7所示，TCI索引＝0的TCI配置共计有2个TCI状态，则其对应的重传等级＝1，TCI索引＝1的TCI配置共计有4个TCI状态，则其对应的重传等级＝2。重传等级与重传次数的对应关系可以参考上述表3，此处不再赘述。

对于指示方式3，可以新增一条用于指示重复因子的RRC信令、DCI信令或其他信令，本申请实施例不再赘述。
在本申请实施例中，网络设备可以通过上述DCI信令、RRC信令或其他信令，下发上述表1-表2、或表4-表5、或表6-表7中任一PDSCH对应的重复因子和配置信息，例如可以直接下发具体的配置参数，如表1中的{K0,S,L,N}、表2中的{K0,S,L,C}，也可以只下发索引值，如表1或表2中的PDSCH索引，以及表4或表5中的TCI索引，本申请对于候选资源的重复因子和配置参数的下发方式，不做具体限定。下面以DCI信令为例说明上述候选资源的配置场景。
示例性地，图4为一种半静态反馈机制的场景示意图。如图4所示，假定网络设备在时隙i+1下发承载有PDSCH1的配置信息的下行控制信息(downlink control information，DCI)1，在时隙i下发承载有PDSCH2的配置信息的DCI2。其中，DCI1对应的K0＝1，K1＝1，重传次数＝2，DCI2对应的K0＝1，K1＝3，重传次数＝1，则在PDSCH1(包括时隙i+2和时隙i+3)上发送的数据块1，以及在PDSCH2上发送的数据块2对应的反馈信息可以在时隙i+4上的PUCCH上反馈。其中，对于一个PDSCH，K0表示调度该PDSCH的DCI所在时隙与该PDSCH所在时隙之间的时隙偏移量，且K0、S、L，且所有候选资源各自对应的{K0,S,L}组成R集合，以及K1表示该PDSCH占用的 最后一个时隙与用于承载反馈信息的时隙之间的时隙偏移量，所有候选资源的K1取值组成一个K1集合。关于R集合中的K0、S、L，以及K1集合可以参考现有实现方式，本申请实施例不再赘述。
此外，上述候选资源可以适用于蜂窝网中的PDSCH，也可以适用于其他无线通信系统。例如，在V2X系统中，网络设备也可以向终端设备(包括发送终端和接收终端)下发多个候选物理侧行链路共享信道(physical sidelink shared channel，PSSCH)各自对应的重复因子和配置信息。
S302，终端设备根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息。
在一种可能的设计方法中，上述S302，终端设备根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息，可以包括:
步骤一，终端设备根据重复因子和配置信息，确定至少两个候选资源各自对应的第一结束符号的位置。
步骤二，终端设备根据至少两个候选资源各自对应的第一结束符号的位置，确定第二结束符号的位置；其中，第二结束符号为至少两个候选资源各自对应的第一结束符号中符号编号最小的符号。
步骤三，终端设备根据第二结束符号的位置，以及至少两个候选资源中，除第二结束符号对应的候选资源之外的其他候选资源占用的第一个符号的位置，确定第一传输时机；其中，第一传输时机对应一个或多个候选资源。
步骤四，终端设备确定第一传输时机对应的反馈信息。
其中，可选地，上述步骤一中至少两个候选资源中任一候选资源对应的第一结束符号可通过如下任一方式确定：
若任一候选资源跨多个时间单元，则任一候选资源对应的第一结束符号可以为：任一候选资源在多个时间单元中占用的最后一个符号中符号编号最小的符号，或者，任一候选资源在多个时间单元中占用的最后一个符号。或者，可选地，若任一候选资源只包括第一时间单元，则任一候选资源对应的第一结束符号为：任一候选资源在第一时间单元中占用的最后一个符号。
示例性地，上述至少两个候选资源包括第一候选资源和第二候选资源；第二结束符号为第一候选资源对应的第一结束符号。相应地，上述步骤三，终端设备根据第二结束符号的位置，以及至少两个候选资源中，除第二结束符号对应的候选资源之外的其他候选资源占用的第一个符号的位置，确定第一传输时机，可以包括：
若第一候选资源和第二候选资源满足第一条件，则终端设备将第一候选资源和第二候选资源确定为第一传输时机。其中，第一条件可以包括：第二候选资源在第二时间单元上占用的第一个符号的符号编号小于或等于第二结束符号的符号编号的符号。其中，第二时间单元为根据第二候选资源对应的重复因子的指示信息和配置信息确定的最后一个时间单元。
在一种可能的设计方法中，若配置了多于两个候选资源，可能需要多次执行上述操作。示例性的，当终端设备经过上述一轮操作，将第一候选资源和第二候选资源确定为第一传输时机之后，候选资源集合中还包括第三候选资源和第四候选资源。进一 步的，终端设备还可以根据第三候选资源和第四候选资源各自的第一结束符号位置，确定第三结束符号位置，第三结束符号位置为第三候选资源和第四候选资源各自的第一结束符号中符号编号最小的第一结束符号，然后根据第三结束符号确定第二传输时机。以此类推，直到上述至少两个候选资源中的所有候选资源均对应了一个传输时机为止。
示例性的，上述多次操作中，给定一个承载HARQ-ACK反馈信息的时隙，根据某一个K1取值可以确定该K1取值对应的时隙内所有的PDSCH时机，进而确定HARQ-ACK反馈比特。若K1配置了多个取值，则对于每个K1取值，均需要执行上述操作确定每个取值对应的时隙内所有的PDSCH时机，进而确定每个K1取值对应的HARQ-ACK反馈比特。上述操作假设了PDSCH不会跨时隙调度。
其中，时间单元可以为完整时隙(full slot)，也可以为短时隙(short slot，又称为mini slot)，本申请实施例对此不作限定。下文示例均以完整时隙(下文简称为时隙)进行说明。
下面结合具体示例，详细说明第一结束符号的确定方法，以及如何根据第一结束符号确定第二结束符号和传输时机，进而确定反馈信息。
示例性地，表8示出了指示方式1的示例四。如表8所示，PDSCH索引＝0的PDSCH0占用符号2-符号13，PDSCH索引＝1的PDSCH1占用符号2-符号5，PDSCH索引＝2的PDSCH2占用符号6-符号9，PDSCH索引＝3的PDSCH3占用符号10-符号13。

3 类型B 0 10 4 2
在一种可能的实现方式中，假定表8中的L表示N次重传的总长度，且4个候选PDSCH上的N次重传均限定在同一个时隙内完成，则如图5所示，以一个特定slot为例，对于PDSCH0，第1次至第4次传输(分别对应图5中的n＝1至n＝4)分别占用该时隙的符号2-符号4、符号5-符号7、符号8-符号10、符号11-符号13，即PDSCH0对应的第一结束符号为符号13，其占用的第一个符号为符号2。同理，对于PDSCH1，只有1次传输，占用该时隙的符号2-符号5，即PDSCH1对应的第一结束符号为符号5，其占用的第一个符号为符号2。对于PDSCH2，第1次和第2次传输分别占用该时隙的符号6-符号7、符号8-符号9，即PDSCH2对应的第一结束符号为符号9，其占用的第一个符号为符号6。对于PDSCH3，第1次和第2次传输分别占用该时隙的符号10-符号11、符号12-符号13，即PDSCH3对应的第一结束符号为符号13，其占用的第一个符号为符号10。也就是说，PDSCH0-PDSCH3各自对应的第一结束符号依次为：符号13、符号5、符号9和符号13，则第二结束符号为上述4个第一结束符号中符号编号最小的符号，也就是第二结束符号为PDSCH1的第一结束符号，即符号5。
然后，以PDSCH1为第一候选资源，分别以PDSCH0、PDSCH2、PDSCH3为第二候选资源，分别判断PDSCH1与PDSCH0、PDSCH1与PDSCH2，以及PDSCH1与 PDSCH3是否满足第一条件。示例性地，参考图5，PDSCH0占用的第一个符号，即符号2小于或等于第二结束符号，即符号5，也就是说PDSCH1与PDSCH0满足第一条件，因此PDSCH1与PDSCH0对应同一个传输时机，可以对应同一组反馈信息。示例性地，参考图5，PDSCH2占用的第一个符号，即符号6，大于第二结束符号，即符号5，也就是说PDSCH1与PDSCH2不满足第一条件，因此PDSCH1与PDSCH2对应不同的传输时机，不能对应同一组反馈信息。同理可知，PDSCH1与PDSCH3也对应不同的传输时机，不能对应同一组反馈信息。
需要说明的是，图5所示的确定反馈信息的方法可以迭代执行，直到所有候选资源所对应的传输时机确定完毕为止。示例性地，如图5所示，经过上一轮操作之后，上述多个候选资源中还有PDSCH2与PDSCH3共计2个候选资源没有确定对应的传输时机。因此，还可以PDSCH2与PDSCH3作为新的至少两个候选资源，再次进行上述步骤一至步骤四。容易理解，PDSCH2与PDSCH3不满足第一条件，分别对应不同的传输时机，不能对应同一组反馈信息。
进一步的，若K1集合中配置了多个K1取值，则图5所示的确定反馈信息的方法可以在每个K1取值对应的时隙内迭代执行。
综上可知，PDSCH0与PDSCH1可以对应同一组反馈信息，PDSCH2和PDSCH3需要分别预留一组反馈信息，即PDSCH0-PDSCH3共计需要预留3组反馈信息。
在另一种可能的实现方式中，假定表8中的L表示N次重传中每次重传的长度，且对于每个候选PDSCH，不同传输可占用不同时隙中的相同符号，则如图6所示，对于PDSCH0，第1次至第4次传输(分别对应图6中的n＝1至n＝4)分别占用时隙i的符号2-符号13、时隙i+1的符号2-符号13、时隙i+2的符号2-符号13、时隙i+3的符号2-符号13，即PDSCH0对应的第一结束符号为符号13，其占用的第一个符号包括符号2。同理，对于PDSCH1，只有1次传输，占用时隙i+3的符号2-符号5，即PDSCH1对应的第一结束符号为符号5，其占用的第一个符号包括符号2。对于PDSCH2，第1次和第2次传输分别占用时隙i+2的符号6-符号9、时隙i+3的符号6-符号9，即PDSCH2对应的第一结束符号为符号9，其占用的第一个符号包括符号6。对于PDSCH3，第1次和第2次传输分别占用时隙i+2的符号10-符号13、时隙i+3的符号10-符号13，即PDSCH3对应的第一结束符号为符号13，其占用的第一个符号包括符号10。也就是说，PDSCH0-PDSCH3各自对应的第一结束符号依次为：符号13、符号5、符号9和符号13，则第二结束符号为上述4个第一结束符号中符号编号最小的符号，也就是第二结束符号为PDSCH1的第一结束符号，即符号5。
然后，以PDSCH1为第一候选资源，分别以PDSCH0、PDSCH2、PDSCH3为第二候选资源，分别判断PDSCH1与PDSCH0、PDSCH1与PDSCH2，以及PDSCH1与PDSCH3是否满足第一条件。示例性地，参考图6，PDSCH0占用的第一个符号，即符号2小于或等于第二结束符号，即符号5，也就是说PDSCH1与PDSCH0满足第一条件，因此PDSCH1与PDSCH0对应同一个传输时机，可以对应同一组反馈信息。示例性地，参考图6，PDSCH2占用的第一个符号，即符号6大于第二结束符号，即符号5，也就是说PDSCH1与PDSCH2不满足第一条件，因此PDSCH1与PDSCH2对应不同的传输时机，不能对应同一组反馈信息。
需要说明的是，图6所示的确定反馈信息的方法可以迭代执行，直到所有候选资源所对应的传输时机确定完毕为止。示例性地，如图6所示，经过上一轮操作之后，上述多个候选资源中还有PDSCH2与PDSCH3共计2个候选资源没有确定对应的传输时机。因此，还可以PDSCH2与PDSCH3作为新的至少两个候选资源，再次执行上述步骤一至步骤四。容易理解，PDSCH2与PDSCH3不满足第一条件，分别对应不同的传输时机，不能对应同一组反馈信息。
综上可知，PDSCH0与PDSCH1对应同一个传输时机，可以对应同一组反馈信息，而PDSCH2和PDSCH3需要分别预留一组反馈信息，即PDSCH0-PDSCH3共计需要预留3组反馈信息。
在又一种可能的实现方式中，假定表8中的各PDSCH的占用的第二时间单元为时隙i+3，L表示N次重传中每次重传的长度，且对于每个候选PDSCH，N次重传可以跨时间单元，且相邻两次传输需要占用连续符号，则如图7所示，对于PDSCH0，第1次至第4次传输(分别对应图7中的n＝1至n＝4)分别占用时隙i的符号2-符号13、时隙i+1的符号0-符号11、时隙i+1的符号12-时隙i+2的符号9、时隙i+2的符号10-时隙i+3的符号7，即PDSCH0对应的第一结束符号为符号7，其占用的第一个符号为符号0。同理，对于PDSCH1，只有1次传输，占用时隙i+3的符号2-符号5，即PDSCH1对应的第一结束符号为符号5，其占用的第一个符号为符号2。对于PDSCH2，第1次和第2次传输分别占用时隙i+3的符号6-符号9、时隙i+3的符号10-符号13，即PDSCH2对应的第一结束符号为符号13，其占用的第一个符号为符号6。对于PDSCH3，第1次和第2次传输分别占用时隙i+2的符号10-符号13、时隙i+3的符号0-符号3，即PDSCH3对应的第一结束符号为符号3，其占用的第一个符号为符号0。也就是说，PDSCH0-PDSCH3各自对应的第一结束符号依次为：符号7、符号5、符号13和符号3，则第二结束符号为上述4个第一结束符号中符号编号最小的符号，也就是第二结束符号为PDSCH3的第一结束符号，即符号3。
然后，以PDSCH3为第一候选资源，以PDSCH0、PDSCH1、PDSCH2为第二候选资源，分别判断PDSCH3与PDSCH0、PDSCH3与PDSCH1，以及PDSCH3与PDSCH2是否满足第一条件。示例性地，参考图7，PDSCH0占用的第一个符号，即符号0小于或等于第二结束符号，即符号3，也就是说PDSCH3与PDSCH0满足第一条件，因此PDSCH3与PDSCH0对应同一个传输时机，可以对应同一组反馈信息。同理可知，PDSCH1占用的第一个符号，即符号2小于或等于第二结束符号，即符号3，也就是说PDSCH3与PDSCH1满足第一条件，因此PDSCH3与PDSCH1对应同一个传输时机，可以对应同一组反馈信息。示例性地，参考图7，PDSCH2占用的第一个符号，即符号6大于第二结束符号，即符号3，也就是说PDSCH3与PDSCH2不满足第一条件，因此PDSCH3与PDSCH2对应不同的传输时机，不能对应同一组反馈信息。
综上可知，PDSCH0、PDSCH1、PDSCH3对应同一个传输时机，可以对应同一组反馈信息，而PDSCH2需要预留另一组反馈信息，即PDSCH0-PDSCH3共计需要预留2组反馈信息。
需要说明的是，上述至少两个候选资源各自对应的第一结束符号也可以通过如下方式确定：上述至少两个候选资源中任一候选资源对应的第一结束符号可以为：与该 任一候选资源占用的第一个时间单元中的第一个符号之间的符号偏移量为L*N+s*(N-1)-1的符号。其中，L为该任一候选资源上的一次传输占用的符号长度，N为重复因子对应的重传次数，s为相邻两次传输之间间隔的符号数，即前一次传输占用的最后一个符号与后一次传输占用的第一个符号之间间隔的符号数。容易理解，若相邻两次传输占用的符号连续，即前一次传输占用的最后一个符号与后一次传输占用的第一个符号连续，则s＝0。也就是说，任一候选资源对应的第一结束符号的符号编号为：[S1+L*N+s*(N-1)-1]％S。其中，S1为该任一候选资源占用的第一个时间单元中的第一个符号的符号编号，S为一个时间单元包含的符号总数，如对于一个正常循环前缀(normal prefix，NCP)的完整时隙，S＝14。
下面以PDSCH0为例，并结合表8，以及图5-图7分别予以说明。其中，时间单元为时隙，N＝4，S＝14，S1＝2。
示例性地，针对图5所示场景，一次传输占用的符号长度L＝3，s＝0，则第一结束符号与S1之间的符号偏移量为：3*4+0*(4-1)-1＝11个符号，第一结束符号的符号编号为：[2+3*4+0*(4-1)-1]％14＝13。
示例性地，针对图6所示场景，一次传输占用的符号长度L＝12，s＝2，则第一结束符号与S1之间的符号偏移量为：12*4+2*(4-1)-1＝53个符号，第一结束符号的符号编号为：[2+12*4+2*(4-1)-1]％14＝13。
示例性地，针对图7所示场景，一次传输占用的符号长度L＝12，s＝0，则第一结束符号与S1之间的符号偏移量为：12*4+0*(4-1)-1＝47个符号，第一结束符号的符号编号为：[2+12*4+0*(4-1)-1]％14＝7。
在另一种可能的设计方法中，上述S302，终端设备根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息，可以包括:
步骤五，终端设备根据重复因子和配置信息，确定至少两个候选资源各自对应的第一起始符号的位置。
步骤六，终端设备根据至少两个候选资源各自对应的第一起始符号的位置，确定第二起始符号的位置；其中，第二起始符号为至少两个候选资源各自对应的第一起始符号中符号编号最大的符号。
步骤七，终端设备根据第二起始符号的位置，以及至少两个候选资源中，除第二起始符号对应的候选资源之外的其他候选资源占用的最后一个符号的位置，确定第一传输时机；其中，第一传输时机对应一个或多个候选资源。
步骤八，终端设备确定第一传输时机对应的反馈信息。
其中，可选地，上述步骤五中至少两个候选资源中任一候选资源对应的第一起始符号可通过如下任一方式确定：
若任一候选资源跨多个时间单元，则任一候选资源对应的第一起始符号为：任一候选资源在多个时间单元中占用的第一个符号中符号编号最小的符号。或者，可选地，若任一候选资源只包括第一时间单元，则任一候选资源对应的第一起始符号为：任一候选资源在第一时间单元中占用的第一个符号。
示例性地，上述至少两个候选资源可以包括第一候选资源和第二候选资源；第二起始符号为第一候选资源对应的第一起始符号。相应地，上述步骤七，终端设备根据 第二起始符号的位置，以及至少两个候选资源中，除第二起始符号对应的候选资源之外的其他候选资源占用的最后一个符号的位置，确定第一传输时机，可以包括：
若第一候选资源和第二候选资源满足第二条件，则终端设备将第一候选资源和第二候选资源确定为第一传输时机。其中，第二条件可以包括：第二候选资源在第二时间单元上占用的最后一个符号的符号编号大于或等于第二起始符号的符号编号的符号。其中，第二时间单元为根据第二候选资源对应的重复因子的指示信息和配置信息确定的最后一个时间单元。
下面结合表8、图5-图7，详细说明第一起始符号的确定方法，以及如何根据第一起始符号确定第二起始符号和传输时机，进而确定反馈信息。
在一种可能的实现方式中，假定表8中的L表示N次重传的总长度，且4个候选PDSCH上的N次重传均限定在同一个时隙内完成，则如图5所示，对于PDSCH0，第1次至第4次传输(分别对应图5中的n＝1至n＝4)分别占用该时隙的符号2-符号4、符号5-符号7、符号8-符号10、符号11-符号13，即PDSCH0对应的第一起始符号为符号2，其占用的最后一个符号包括符号13。同理，对于PDSCH1，只有1次传输，占用该时隙的符号2-符号5，即PDSCH1对应的第一起始符号为符号2，其占用的最后一个符号包括符号5。对于PDSCH2，第1次和第2次传输分别占用该时隙的符号6-符号7、符号8-符号9，即PDSCH2对应的第一起始符号为符号6，其占用的最后一个符号包括符号9。对于PDSCH3，第1次和第2次传输分别占用该时隙的符号10-符号11、符号12-符号13，即PDSCH3对应的第一起始符号为符号10，其占用的最后一个符号包括符号13。也就是说，PDSCH0-PDSCH3各自对应的第一起始符号依次为：符号2、符号2、符号6和符号10，则第二起始符号为上述4个第一起始符号中符号编号最大的符号，也就是第二起始符号为PDSCH3的第一起始符号，即符号10。
然后，以PDSCH3为第一候选资源，分别以PDSCH0、PDSCH1、PDSCH2为第二候选资源，分别判断PDSCH3与PDSCH0、PDSCH3与PDSCH1，以及PDSCH3与PDSCH2是否满足第二条件。示例性地，参考图5，PDSCH0占用的最后一个符号，即符号13大于或等于第二起始符号，即符号10，也就是说PDSCH3与PDSCH0满足第二条件，因此PDSCH3与PDSCH0对应同一个传输时机，可以对应同一组反馈信息。示例性地，参考图5，PDSCH1占用的最后一个符号，即符号5小于第二起始符号，即符号10，也就是说PDSCH3与PDSCH1不满足第二条件，因此PDSCH3与PDSCH1对应不同的传输时机，不能对应同一组反馈信息。同理可知，PDSCH3与PDSCH2对应不同的传输时机，不能对应同一组反馈信息。
需要说明的是，图5所示的确定反馈信息的方法可以迭代执行，直到所有候选资源所对应的传输时机确定完毕为止。示例性地，如图5所示，经过上一轮操作之后，上述多个候选资源中还有PDSCH1与PDSCH2共计2个候选资源，则可以PDSCH1与PDSCH2作为新的至少两个候选资源，再次执行上述步骤五至步骤八。参考上述操作可知，PDSCH1与PDSCH2不满足第二条件，分别对应两个传输时机，不能对应同一组反馈信息。
综上可知，PDSCH0与PDSCH3可以对应同一组反馈信息，PDSCH1和PDSCH2需要分别预留一组反馈信息，即PDSCH0-PDSCH3共计需要预留3组反馈信息。
在另一种可能的实现方式中，假定表8中的L表示N次重传中每次重传的长度，且对于每个候选PDSCH，每次重传均需要占用不同时隙中的相同符号，则如图6所示，对于PDSCH0，第1次至第4次传输(对应图6中的n＝1至n＝4)分别占用时隙i的符号2-符号13、时隙i+1的符号2-符号13、时隙i+2的符号2-符号13、时隙i+3的符号2-符号13，即PDSCH0对应的第一起始符号为符号2，其占用的最后一个符号包括符号13。同理，对于PDSCH1，只有1次传输，占用时隙i+3的符号2-符号5，即PDSCH1对应的第一起始符号为符号2，其占用的最后一个符号包括符号5。对于PDSCH2，第1次和第2次传输分别占用时隙i+2的符号6-符号9、时隙i+3的符号6-符号9，即PDSCH2对应的第一起始符号为符号6，其占用的最后一个符号包括符号9。对于PDSCH3，第1次和第2次传输分别占用时隙i+2的符号10-符号13、时隙i+3的符号10-符号13，即PDSCH3对应的第一起始符号为符号10，其占用的最后一个符号包括符号13。也就是说，PDSCH0-PDSCH3各自对应的第一起始符号依次为：符号2、符号2、符号6和符号10，则第二起始符号为上述4个第一起始符号中符号编号最大的符号，也就是第二起始符号为PDSCH3的第一起始符号，即符号10。
然后，以PDSCH3为第一候选资源，分别以PDSCH0、PDSCH1、PDSCH2为第二候选资源，分别判断PDSCH3与PDSCH0、PDSCH3与PDSCH1，以及PDSCH3与PDSCH2是否满足第二条件。示例性地，参考图6，PDSCH0占用的最后一个符号，即符号13大于或等于第二起始符号，即符号10，也就是说PDSCH3与PDSCH0满足第二条件，因此PDSCH3与PDSCH0对应同一个传输时机，可以对应同一组反馈信息。示例性地，参考图6，PDSCH1占用的最后一个符号，即符号5小于第二起始符号，即符号10，也就是说PDSCH3与PDSCH1不满足第二条件，因此PDSCH3与PDSCH1对应不同的传输时机，不能对应同一组反馈信息。同理可知，PDSCH2占用的最后一个符号，即符号9小于第二起始符号，即符号10，也就是说PDSCH3与PDSCH2不满足第二条件，因此PDSCH3与PDSCH2对应不同的传输时机，不能对应同一组反馈信息。
需要说明的是，图6所示的确定反馈信息的方法可以迭代执行，直到所有候选资源所对应的传输时机确定完毕为止。示例性地，如图6所示，经过上一轮操作之后，上述多个候选资源中还有PDSCH1与PDSCH2共计2个候选资源，则可以PDSCH1与PDSCH2作为新的至少两个候选资源，再次执行上述步骤五至步骤八。参考上述操作可知，PDSCH1与PDSCH2不满足第二条件，分别对应两个传输时机，不能对应同一组反馈信息。
综上可知，PDSCH0与PDSCH3对应同一个传输时机，可以对应同一组反馈信息，而PDSCH1和PDSCH2需要分别预留一组反馈信息，即PDSCH0-PDSCH3共计需要预留3组反馈信息。
在又一种可能的实现方式中，假定表8中的各PDSCH的占用的第二时间单元为时隙i+3，L表示N次重传中每次重传的长度，且对于每个候选PDSCH，N次重传可以跨时间单元，且相邻两次传输需要占用连续符号，则如图7所示，对于PDSCH0，第1次至第4次传输(对应图7中的n＝1至n＝4)分别占用时隙i的符号2-符号13、时隙i+1的符号0-符号11、时隙i+1的符号12-时隙i+2的符号9、时隙i+2的符号10- 时隙i+3的符号7，即PDSCH0对应的第一起始符号为符号0，其占用的最后一个符号为符号7。同理，对于PDSCH1，只有1次传输，占用时隙i+3的符号2-符号5，即PDSCH1对应的第一起始符号为符号2，其占用的最后一个符号包括符号5。对于PDSCH2，第1次和第2次传输分别占用时隙i+3的符号6-符号9、时隙i+3的符号10-符号13，即PDSCH2对应的第一起始符号为符号6，其占用的最后一个符号包括符号13。对于PDSCH3，第1次和第2次传输分别占用时隙i+2的符号10-符号13、时隙i+3的符号0-符号3，即PDSCH3对应的第一起始符号为符号0，其占用的最后一个符号为符号3。也就是说，PDSCH0-PDSCH3各自对应的第一起始符号依次为：符号0、符号2、符号6和符号0，则第二起始符号为上述4个第一起始符号中符号编号最大的符号，也就是第二起始符号为PDSCH2的第一起始符号，即符号6。
然后，以PDSCH2为第一候选资源，分别以PDSCH0、PDSCH2、PDSCH3为第二候选资源，分别判断PDSCH2与PDSCH0、PDSCH2与PDSCH1，以及PDSCH2与PDSCH3是否满足第二条件。示例性地，参考图7，PDSCH0占用的最后一个符号，即符号7大于或等于第二起始符号，即符号6，也就是说PDSCH2与PDSCH0满足第二条件，因此PDSCH2与PDSCH0对应同一个传输时机，可以对应同一组反馈信息。PDSCH1占用的最后一个符号，即符号5小于第二起始符号，即符号6的符号，也就是说PDSCH2与PDSCH1不满足第二条件，因此PDSCH2与PDSCH1对应不同的传输时机，不能对应同一组反馈信息。同理可知，PDSCH3占用的最后一个符号，即符号3小于第二起始符号，即符号6，也就是说PDSCH3与PDSCH2不满足第二条件，因此PDSCH3与PDSCH2对应不同的传输时机，不能对应同一组反馈信息。
需要说明的是，图7所示的确定反馈信息的方法可以迭代执行，直到所有候选资源所对应的传输时机确定完毕为止。示例性地，如图7所示，经过上一轮操作之后，上述多个候选资源中还有PDSCH1与PDSCH3共计2个候选资源，则可以PDSCH1与PDSCH3作为新的至少两个候选资源，再次执行上述步骤五至步骤八。参考上述操作可知，PDSCH1与PDSCH3不满足第二条件，分别对应两个传输时机，不能对应同一组反馈信息。
综上可知，PDSCH0、PDSCH2、PDSCH3对应同一个传输时机，可以对应同一组反馈信息，而PDSCH1需要预留另一组反馈信息，即PDSCH0-PDSCH3共计需要预留2组反馈信息。
应理解，同一个传输时机，如上述第一传输时机，对应的多个候选资源中，任意两个候选资源之间存在交叠。其中，“交叠”是指该同一个传输时机对应的多个候选资源中任意两个候选资源之间在时域位置上存在交集，如包含相同符号。例如，如图5所示，第一传输时机可以对应PDSCH0和PDSCH1，其中，PDSCH0和PDSCH1均包括符号2-符号5。或者，第一传输时机可以对应PDSCH0和PDSCH3，其中，PDSCH0和PDSCH3均包括符号10-符号13。
需要说明的是,上述多个候选资源中的每个候选资源均可以对应一个或者多个传输时机，每个传输时机对应不同的时间间隔，该时间间隔为承载反馈信息的时间单元与多个候选资源所占的最后一个时间单元之间间隔的时间单元数量，在同一个所述时间间隔的情况下，所述第一传输时机对应的多个候选资源中任意两个候选资源之间存 在交叠。例如，如图8所示，R集合的配置对应下表9，可见存在4个候选资源，每个候选资源分别对应一个重传次数N，则可能的PDSCH所占用的资源如图8所示。假设K1的取值为{1,2}，且N次传输跨时隙,以及承载反馈信息的时隙为i+3，则需要分别针对K1的两个取值确定各候选PDSCH时机。具体为，对于K1＝2，即PDSCH0的结束符号位于时隙i+1的情况，PDSCH0的结束符号根据PDSCH索引0对应的配置参数以及相应的重传次数N＝4，可以确定其结束符号为7，PDSCH1的结束符号根据PDSCH索引1对应的配置参数以及相应的重传次数N＝1，可以确定其结束符号为5，PDSCH2的结束符号根据PDSCH索引2对应的配置参数以及相应的重传次数N＝2，可以确定其结束符号为13，PDSCH3的结束符号根据PDSCH索引3对应的配置参数以及相应的重传次数N＝2，可以确定其最后一个时隙内的结束符号为3，则PDSCH3对应的结束符号的符号编号在K1＝2对应的时隙内是最小的，以其为基准判断第一传输时机所对应的候选资源。具体地，PDSCH0的最后一个slot内的起始符号的符号编号小于PDSCH3的结束符号的符号编号，所以PDSCH0对应第一传输时机，PDSCH1仅占用一个时隙，则其起始符号的符号编号小于PDSCH3的结束符号的符号编号，所以PDSCH1也对应第一传输时机，而PDSCH索引2的起始符号的符号编号大于PDSCH3的结束符号的符号编号，则第一传输时机对应PDSCH0、PDSCH1和PDSCH3。R集合中排除PDSCH0、PDSCH1和PDSCH3之后仅剩余PDSCH2，则第二传输时机对应PDSCH2。依据上述分析可知,该承载HARQ-ACK反馈的时隙i+3上会反馈两组HARQ-ACK比特，各自对应第一传输时机和第二传输时机，比如第一传输时机对应第一组HARQ-ACK比特，第二传输时机对应第二组HARQ-ACK比特。

需要说明的是，上述反馈时隙，即时隙i+3可以是根据配置其他PDSCH，如PDSCH4的DCI所在时隙、DCI指示的K0和K1取值确定的反馈时隙。也就是说，根据网络调度信息，已经确定需要在时隙i+3上反馈PDSCH4对应的HARQ-ACK比特。时隙i+3可以是根据配置PDSCH0-3中任意一个或多个PDSCH的DCI所在时隙、DCI指示的K0和K1取值确定的反馈时隙。在此情况下，终端设备还需要在已确定的反馈时隙，即时隙i+3上发送表9所示的各PDSCH对应的HARQ-ACK比特。其原因在于：网络设备已经通过其他DCI配置了表9中的部分或全部PDSCH，但是由于信道质量较差、干扰严重等原因，导致终端设备没有收到用于配置表9中的部分或全部PDSCH的DCI，但是网络并不知道这一点，需要终端设备在反馈时隙中反馈表9中的所有PDSCH对应的HARQ-ACK比特，以告知网络设备是否配置了表9中的PDSCH，以及配置了哪些PDSCH，并据此对已经配置、且终端设备反馈NACK的PDSCH进行重传。
在本申请实施例中，上述重复因子对应的重传次数是指网络设备调度的重传次数。在实际的数据传输过程中，重传次数还可以进一步根据帧结构，如上下行子帧配比或 上下行符号配比进行调整。示例性地，当1个时隙内有一些符号可以被配置为用于上行传输的上行符号，当某一次重复传输的PDSCH占用了该上行子帧或符号时，可以丢弃掉包含该上行子帧或符号的重复传输，则实际的重传次数会发生变化。例如，参考表8和图5，PDSCH0共计包括4次传输，假定第3次传输(对应n＝3)占用的符号8和符号9被配置为上行符号，则丢弃第3次传输。此外，对于包含上行符号的传输之后的其他传输，如第4次传输(对应n＝4)，可以丢弃，也可以恢复，本申请实施例对此不作限定。当第4次传输丢弃时，实际重传次数为2，当第4次重传没有丢弃时，实际重传次数为3。
S303，网络设备根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息。

步骤十二，网络设备确定第一传输时机对应的反馈信息。
可选地，上述至少两个候选资源中任一候选资源对应的第一结束符号可通过如下任一方式确定：若任一候选资源跨多个时间单元，则任一候选资源对应的第一结束符号为：任一候选资源在多个时间单元中占用的最后一个符号中符号编号最小的符号，或者，任一候选资源在所述多个时间单元中占用的最后一个符号。或者，可选地，若任一候选资源只包括第一时间单元，则任一候选资源对应的第一结束符号为：任一候选资源在第一时间单元中占用的最后一个符号。
示例性地，上述至少两个候选资源包括第一候选资源和第二候选资源；第二结束符号为第一候选资源对应的第一结束符号。相应地，上述网络设备根据第二结束符号的位置，以及至少两个候选资源中，除第二结束符号对应的候选资源之外的其他候选资源占用的第一个符号的位置，确定第一传输时机，可以包括：若第一候选资源和第二候选资源满足第一条件，则网络设备将第一候选资源和第二候选资源确定为第一传输时机。其中，第一条件可以包括：第二候选资源在第二时间单元上占用的第一个符号的符号编号小于或等于第二结束符号的符号编号的符号。其中，第二时间单元为根据第二候选资源对应的重复因子的指示信息和配置信息确定的最后一个时间单元。
在另一种可能的设计方法中，上述S303，网络设备根据重复因子和配置信息，确定至少两个候选资源对应的反馈信息，可以包括:
步骤十三，网络设备根据重复因子和配置信息，确定至少两个候选资源各自对应的第一起始符号的位置。
步骤十四，网络设备根据至少两个候选资源各自对应的第一起始符号的位置，确定第二起始符号的位置；其中，第二起始符号为至少两个候选资源各自对应的第一起始符号中符号编号最大的符号。
步骤十五，网络设备根据第二起始符号的位置，以及至少两个候选资源中，除第二起始符号对应的候选资源之外的其他候选资源占用的最后一个符号的位置，确定第一传输时机；其中，第一传输时机对应一个或多个候选资源。
步骤十六，网络设备确定第一传输时机对应的反馈信息。
可选地，上述至少两个候选资源中任一候选资源对应的第一起始符号可通过如下任一方式确定：若任一候选资源跨多个时间单元，则任一候选资源对应的第一起始符号为：任一候选资源在多个时间单元中占用的第一个符号中符号编号最小的符号。或者，可选地，若任一候选资源只包括第一时间单元，则任一候选资源对应的第一起始符号为：任一候选资源在第一时间单元中占用的第一个符号。
示例性地，上述至少两个候选资源包括第一候选资源和第二候选资源；第二起始符号为第一候选资源对应的第一起始符号。相应地，上述网络设备根据第二起始符号的位置，以及至少两个候选资源中，除第二起始符号对应的候选资源之外的其他候选资源占用的最后一个符号的位置，确定第一传输时机，可以包括：若第一候选资源和第二候选资源满足第二条件，则网络设备将第一候选资源和第二候选资源确定为第一传输时机。其中，第二条件可以包括：第二候选资源在第二时间单元上占用的最后一个符号的符号编号大于或等于第二起始符号的符号编号的符号。其中，第二时间单元为根据第二候选资源对应的重复因子的指示信息和配置信息确定的最后一个时间单元。
需要说明的是，S303与S302的区别仅在于执行主体不同。因此，S303的具体实现方式，可以参考S302的相关描述，如步骤九至步骤十六可以分别参考步骤一至步骤八，S303中涉及的第一条件和第二条件也可以分别参考S302中的第一条件和第二条件，此处不再赘述。
此外，S303可以在S302之后执行，也可以在S302之前执行，还可以在执行S301之前执行，只要在执行S305，网络设备在调用的多个候选资源对应的反馈资源上，接收来自终端设备的反馈信息之前执行完毕即可。
在一些实施例中，S301-S303所述的反馈信息的传输方法可以理解为：在为可能发生的数据传输任务配置多个数据传输资源(如多个候选资源)场景下，预先为配置的多个数据传输资源确定反馈信息。例如，网络设备为终端设备配置一个包含有多个数据传输资源的资源池，网络设备和终端设备可以基于S301-S303所述的反馈信息的传输方法，预先为该资源池中的多个数据传输资源确定并保存多个数据传输资源对应的反馈信息的数量和反馈顺序，以便在数据传输发生时用于发送或接收反馈信息。
在另一些实施例中，S301-S303所述的反馈信息的传输方法也可以理解为：网络设备已经确定有多个数据块需要传输，且为该多个数据块调度了多个候选资源的场景下，实时确定分别用于承载该多个数据块的多个候选资源，以及该多个候选资源对应的反馈信息的数量和反馈顺序，并在之后的数据传输过程中发送或接收反馈信息。因此，当网络设备需要向终端设备发送数据块时，如需要向终端设备发送一个或多个传输块(transmission block，TB)，网络设备和终端设备还需要执行如下步骤：
S304，网络设备在调用的多个候选资源上向终端设备发送多个数据块。相应地，终端设备在调用的多个候选资源上接收来自终端设备的多个数据块。
S305，终端设备在调用的多个候选资源对应的反馈资源上，向网络设备发送反馈信息。相应地，网络设备在调用的多个候选资源对应的反馈资源上，接收来自终端设备的反馈信息。
S304-S305的具体实现方式，例如R集合中{K0,S,L}、K1集合、反馈信息的传输顺序等，可以参考现有实现方式，本申请实施例不再赘述。
