技术领域
本公开涉及通信技术领域，特别是涉及一种数据传输方法、终端设备及网络设备。
背景技术
随着移动通信业务需求的发展变化，国际电信联盟(International Telecommunication Union，ITU)和第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)等组织都开始研究新的无线通信系统，例如第五代新无线通信系统(5 Generation New Radio，5G NR)。
目前5G NR系统中支持灵活的定时关系。对于物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，承载其调度信息的物理下行控制信道(Physical Downlink Control Channel，PDCCH)可指示PDSCH与PDCCH之间的调度定时关系(Scheduling timing)以及PDSCH到其对应的混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)确认HARQ-ACK之间的反馈定时关系(HARQ-ACK timing)。具体地，PDCCH所使用的下行控制信息(Downlink Control Information，DCI)格式中的时域资源分配指示域指示PDSCH所在时隙与DCI所在时隙的时隙偏移K0；DCI格式中的PDSCH到HARQ-ACK反馈定时指示域指示PDSCH到HARQ-ACK之间的时隙个数K1。调度PDSCH的DCI有两种格式，一种是DCI格式1_0，另一种是DCI格式1_1。其中，DCI格式1_0为回退(fallback)DCI，其对应的K1集合固定为{1,2,3,4,5,6,7,8}，DCI格式1_1为非回退(non-fallback)的DCI格式，其对应的K1集合为上述最大K1集合中选择出的最多8个值，需要至少包含{0,1,2,3,4,5,6,7}中的值。K1可以通过DCI中的3比特HARQ-ACK定 时指示域指示一个值至终端设备，因此该值可以是动态改变的。
5G NR系统中支持半静态(semi-static)和动态(dynamic)两种HARQ-ACK码本(codebook)产生方式。所谓HARQ-ACK码本指针对在同一个时域位置或上行信道上进行HARQ-ACK反馈的下行传输(包括PDSCH和指示下行SPS资源释放的PDCCH，指示下行SPS资源释放的PDCCH也可称为SPS PDSCH释放指示)产生的HARQ-ACK反馈序列。
半静态HARQ-ACK码本可以根据K1集合中的HARQ-ACK定时值确定每个载波c上对应在同一个时隙n进行HARQ-ACK反馈的下行传输的位置集合Mc，然后根据Mc即可以确定时隙n中传输的HARQ-ACK码本。具体的，根据每个K1值可确定对应的时隙slot n进行HARQ-ACK反馈的时隙，在这些时隙的每个时隙中，进一步可根据预先配置的下行时域资源分配信息中的各种时域位置，确定一个时隙中时分复用(Time Division Multiplexing，TDM)存在的最大的下行传输的个数。例如，如果配置了半静态的上下行时隙结构，根据一个下行时域资源分配信息确定的在一个时隙中的传输位置中存在上行符号，则该传输位置不计数，因此存在上下行资源冲突，该下行传输实际不会发生，或根据调度定时K0确定的传输该时隙中的下行传输的调度信息的时隙中不存在PDCCH监听时机(PDCCH monitoring occasion)，则说明该时隙不能被调度，该时隙中的下行传输都不能被计数，只有满足一个时隙中根据下行时域资源分配信息确定的符号都为下行或unknown符号且该时隙对应的发送调度信息的时隙中存在PDCCH监听时机时，才说明该下行传输可以在该时隙中存在，从而在一个时隙中可能存在的下行传输中确定最大的TDM传输的下行传输个数，以此类推，确定根据K1得到的对应在slot n中进行HARQ-ACK反馈的多个slot中的总的下行传输个数作为Mc，根据Mc确定在slot n中传输的半静态HARQ-ACK码本，包括码本大小以及HARQ-ACK具体内容和顺序。
目前在5G NR系统中，半静态HARQ-ACK码本的大小通常由在一个时隙中进行HARQ-ACK反馈的下行传输的个数确定，由于在一个时隙中进行HARQ-ACK反馈的下行传输可能是复用在时域位置上的下行传输，即在一个时隙中进行HARQ-ACK反馈的下行传输的个数可能较大，因此根据在一个 时隙中进行HARQ-ACK反馈的下行传输的个数确定的半静态HARQ-ACK码本中，可能存在较多的冗余信息，造成HARQ-ACK反馈信息的传输性能差。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1所示，本公开实施例提供了一种数据传输方法，应用于终端设备，包括如下步骤：
步骤101：接收PDSCH；
步骤102：根据PDSCH的重复传输次数，确定半静态HARQ-ACK码本的大小；
步骤103：根据确定大小的半静态HARQ-ACK码本，对重复传输的PDSCH进行相应的HARQ-ACK反馈。
其中，该重复传输的PDSCH对应的HARQ-ACK反馈信息为重复传输的PDSCH的最后一次传输所对应的HARQ-ACK反馈信息，即经过多次重复传输的合并之后得到的PDSCH的HARQ-ACK反馈信息。
在本公开实施例中，通过根据PDSCH的重复传输次数，确定半静态HARQ-ACK码本的大小，相比于根据在一个时隙中进行HARQ-ACK反馈的下行传输的个数确定的半静态HARQ-ACK码本，能够在保证正常的PDSCH重复传输的HARQ-ACK反馈的基础上，减少半静态HARQ-ACK码本中的冗余信息，进一步根据此半静态HARQ-ACK码本，对重复传输的PDSCH进行相应的HARQ-ACK反馈时，能够提高HARQ-ACK反馈信息的传输性能。
本公开实施例中，终端设备在确定半静态HARQ-ACK码本的大小时，除可根据PDSCH的重复传输次数外，还可进一步根据在一个时隙或物理上行控制信道(Physical Uplink Control Channel，PUCCH)上进行HARQ-ACK反馈的下行传输的个数。具体的，步骤102可包括：
根据PDSCH的重复传输次数以及在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数，确定在一个时隙或PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH的个数；
根据在一个时隙或PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH的个数，确定半静态HARQ-ACK码本的大小。
其中，该在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数可为以下至少一项：
根据PDSCH到对应HARQ-ACK的反馈定时集合中的每个值，确定的下行传输的个数；
根据PDSCH到对应HARQ-ACK的反馈定时集合中的最大值和最小值确定的时隙范围，确定的下行传输的个数；
根据PDSCH到对应HARQ-ACK的反馈定时集合中的每个值以及下行传 输在每个时隙中的时域资源分配候选集合，确定的下行传输的个数；
根据PDSCH到对应HARQ-ACK的反馈定时集合中的最大值和最小值确定的时隙范围以及下行传输在每个时隙中的时域资源分配候选集合，确定的下行传输的个数。
需指出的是，该在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数可以是针对每个载波确定的，即针对每个载波按照上述确定下行传输的个数的方式，确定在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数。此外，该在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数也可以是针对多个载波确定的，即此确定过程中，首先针对每个载波按照上述确定下行传输的个数的方式确定每个载波上对应的下行传输集合，然后对多个载波中的每个载波上对应的下行传输集合取并集，以确定在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数。
进一步的，终端设备根据PDSCH的重复传输次数以及在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数，确定在一个时隙或PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH的个数的过程可为：
按照公式

计算在一个时隙或PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH的个数；
其中，M为在一个时隙或PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH的个数，B为在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数，A为PDSCH的重复传输次数，
Figure PCTCN2019079842-appb-000002
为向上取整的运算符号。
需说明的是，具体实现时，若该重复传输的PDSCH的最后一次传输的位置对应于B个下行传输位置中的第A*i+1到A*(i+1)个位置，则该重复传输的PDSCH为在一个时隙或PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH中的第i+1个重复传输的PDSCH，i为大于或等于0的正整数。
进一步的，步骤103可包括：
终端设备根据重复传输的PDSCH在在一个时隙或PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH中的位置，将该重复传输的PDSCH对应的HARQ-ACK反馈信息映射到半静态HARQ-ACK码本中进行传输。
参见图2所示，本公开实施例提供了一种数据传输方法，应用于网络设备，包括如下步骤：
步骤201：传输PDSCH；
步骤202：根据PDSCH的重复传输次数，确定半静态HARQ-ACK码本的大小；
步骤203：根据确定大小的半静态HARQ-ACK码本，接收重复传输的PDSCH对应的HARQ-ACK反馈信息。
在本公开实施例中，通过根据PDSCH的重复传输次数，确定半静态HARQ-ACK码本的大小，相比于根据在一个时隙中进行HARQ-ACK反馈的下行传输的个数确定的半静态HARQ-ACK码本，能够在保证正常的PDSCH重复传输的HARQ-ACK反馈的基础上，减少半静态HARQ-ACK码本中的冗余信息，进一步根据此半静态HARQ-ACK码本，接收重复传输的PDSCH对应的HARQ-ACK反馈信息，能够提高HARQ-ACK反馈信息的接收性能。

可选的，所述在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数为以下至少一项：
根据PDSCH到对应HARQ-ACK的反馈定时集合中的每个值，确定的下行传输的个数；
根据PDSCH到对应HARQ-ACK的反馈定时集合中的最大值和最小值确定的时隙范围，确定的下行传输的个数；
根据PDSCH到对应HARQ-ACK的反馈定时集合中的每个值以及下行传输在每个时隙中的时域资源分配候选集合，确定的下行传输的个数；
根据PDSCH到对应HARQ-ACK的反馈定时集合中的最大值和最小值确定的时隙范围以及下行传输在每个时隙中的时域资源分配候选集合，确定的 下行传输的个数。
可选的，所述根据所述PDSCH的重复传输次数以及在一个时隙或PUCCH上进行HARQ-ACK反馈的下行传输的个数，确定在所述一个时隙或所述PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH的个数，包括：
按照公式

计算所述在所述一个时隙或所述PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH的个数；
其中，M为在所述一个时隙或所述PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH的个数，B为在所述一个时隙或所述PUCCH上进行HARQ-ACK反馈的下行传输的个数，A为所述PDSCH的重复传输次数，
Figure PCTCN2019079842-appb-000004
为向上取整的运算符号。
可选的，若所述重复传输的PDSCH的最后一次传输的位置对应于B个下行传输位置中的第A*i+1到A*(i+1)个位置，所述重复传输的PDSCH为在所述一个时隙或所述PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH中的第i+1个重复传输的PDSCH，i为大于或等于0的正整数。
可选的，步骤203可包括：
根据所述重复传输的PDSCH在所述一个时隙或所述PUCCH上进行HARQ-ACK反馈的重复传输的PDSCH中的位置，在所述半静态HARQ-ACK码本中的相应位置上接收所述重复传输的PDSCH对应的HARQ-ACK反馈信息。
可选的，所述重复传输的PDSCH对应的HARQ-ACK反馈信息为所述重复传输的PDSCH的最后一次传输所对应的HARQ-ACK反馈信息。
下面，结合图3至图5对本公开具体实施例进行详细说明。
本公开具体实施例中，假设包含8个HARQ-ACK定时的候选集合K1为{2,3,4,5,6,7,8,9}，高层信令预先配置PDSCH进行重复传输，重复传输次数为A＝4，即承载同一个TB的PDSCH需要经过4次重复传输。若以slot为单位进行重复传输，则每次传输在一个包含足够DL或unknown符号的slot中进行，第一个PDSCH传输所在的slot可根据PDCCH的调度确定，例如根据K0确定，PDSCH在一个slot中的时域资源根据PDCCH的调度确定，且重 复传输过程中，每个PDSCH在传输slot中的时域位置相同，在第一个slot开始的后续满足上述一个slot中的PDSCH的时域资源分配的slot中进行重复传输。当前不排除具体实现时还可以在slot内部进行重复传输，比如一个PDSCH被分配的符号个数比较少时，而本公开具体实施例仅以slot为单位进行重复传输。
情况一：若第一个重复传输的PDSCH的第一次传输在slot n，依次在后续slot n+1、n+2和n+3重复传输，第二重复传输的PDSCH的第一次传输在slot n+4,依次在后续slot n+5、n+6和n+7重复传输，则终端设备进行的相应HARQ-ACK反馈过程为：
首先，根据集合中的每个K1值可以确定8个对应在slot n+9中进行HARQ-ACK传输的slot，即slot n到slot n+7，对这些slot中的每一个slot都按照现有相关方式确定PDSCH在该slot中可能存在的最大个数，比如此时假设终端能力仅支持每个slot中仅存在一个PDSCH，且每个slot都在根据K0确定的发送调度信令的slot中存在PDCCH监听时机，则确定每个slot都可以包含一个PDSCH传输，即在一个载波上对应在slot n+9中进行HARQ-ACK反馈的下行传输个数为B＝8，或者，直接根据每一个K1值确定的包含可以被调度的下行资源的slot个数作为下行传输个数，或者，根据K1集合中的最大值和最小值确定一个slot集合范围，在这个集合中确定包含可以被调度的下行资源的slot个数作为下行传输个数，都可以得到B＝8，其中，包含可以被调度的下行资源的slot即判断该slot中是否包含预先配置的每个时隙中的下行传输的时域资源分配候选集合中的至少一个下行时域资源，如果包含，则说明该slot中包含足够的下行符号可以被调度进行PDSCH传输；如图3所示；
其次，按照
Figure PCTCN2019079842-appb-000005
即可判断对应在slot n+9中进行HARQ-ACK反馈的8个下行传输位置中实际上只能包含最多2个重复传输次数为4次的PDSCH；此判断的原因为终端设备对重复传输的PDSCH只针对最后一个PDSCH以及K1值确定HARQ-ACK反馈的时域位置，前几个PDSCH重复传输由于属于一个重复传输的PDSCH的中间过程，可不需要进行HARQ-ACK反馈；因此，此种情况下，可确定M＝2，即对应在slot n+9中进行HARQ-ACK 反馈的重复传输的PDSCH的个数为2个，对应在slot n+9中进行HARQ-ACK反馈的进行重复传输的下行传输位置仅有2个，只针对此2个下行传输位置进行HARQ-ACK反馈即可，如图3所示；
然后，按照HARQ-ACK映射原则，由于终端设备接收到的在slot n+3结束重复传输的PDSCH的结束位置在B＝8个位置中的第4个位置，属于i＝0确定的第1至4个位置的集合中，即属于B个下行传输中可能存在第一个PDSCH重复传输的范围，因此，可确定重复传输的第一个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第1个重复传输的PDSCH；同理，由于终端设备接收到的在slot n+7结束重复传输的PDSCH的结束位置在B＝8个位置中的第8个位置，属于i＝1确定的第5至8个位置的集合中，即属于B个下行传输中可能存在第二个PDSCH重复传输的范围，因此，可确定重复传输的第二个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第2个重复传输的PDSCH；本公开具体实施例中，假设每个重复传输的PDSCH对应的HARQ-ACK为1比特，则每个重复传输的PDSCH对应的HARQ-ACK对应一个HARQ-ACK反馈位置，则在8个下行传输中，实际存在的HARQ-ACK反馈位置为2个，重复传输的第一个PDSCH对应于2个HARQ-ACK反馈位置中的第1个位置，重复传输的第二个PDSCH对应于2个HARQ-ACK反馈位置中的第2个位置，参见图3所示；
最后，按照上述2个HARQ-ACK位置、重复传输的第一个PDSCH对应的HARQ-ACK反馈位置和重复传输的第二个PDSCH对应的HARQ-ACK反馈位置，生成最终的HARQ-ACK反馈序列。
需指出的是，具体实现时，每个重复传输的PDSCH对应的HARQ-ACK除可为1比特外，还可为多比特，取决于下行传输的具体配置，例如是单TB还是多TB、是否进行空间合并、是否支持CBG传输等。在每个重复传输的PDSCH对应的HARQ-ACK为多比特比如2比特的情况下，当重复传输的第一个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第1个PDSCH，重复传输的第二个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第2个PDSCH时，在 8个下行传输中，实际仅存在2个重复传输次数为4的PDSCH，因此只需要对这两个重复传输的PDSCH进行HARQ-ACK反馈，而每个重复传输的PDSCH的HARQ-ACK反馈比特数为2比特，则总的HARQ-ACK反馈比特数为2x2＝4比特，可以等效为4个HARQ-ACK位置，则重复传输的第一个PDSCH对应于4个HARQ-ACK反馈位置中的第1至2个位置，重复传输的第二个PDSCH对应于4个HARQ-ACK反馈位置中的第3至4个位置，并以此生成最终的HARQ-ACK反馈序列；或者也可以理解为，此时还是2个HARQ-ACK反馈位置，每个HARQ-ACK反馈位置对应2比特HARQ-ACK反馈信息，即重复传输的第一个PDSCH的2比特HARQ-ACK映射为第一个HARQ-ACK反馈位置对应的2比特HARQ-ACK反馈信息，重复传输的第二个PDSCH的2比特HARQ-ACK映射为第二个HARQ-ACK反馈位置对应的2比特HARQ-ACK反馈信息，并以此生成最终的HARQ-ACK反馈序列。
此情况下，网络侧比如基站可以按照同样方式确定半静态HARQ-ACK码本的大小以及不同PDSCH重复传输的HARQ-ACK反馈位置，从而从接收到的HARQ-ACK反馈序列中得到每个重复传输的PDSCH对应的HARQ-ACK反馈信息。
情况二：在B个下行传输位置中仅调度了一个PDSCH重复传输，第一次传输在slot n+1，依次在后续slot n+2、n+3和n+4重复传输，则终端设备进行的相应HARQ-ACK反馈过程为：
首先，按照上述情况1的同样方法确定B＝8以及M＝2；在进行HARQ-ACK映射时，由于终端设备接收到的在slot n+4结束重复传输的PDSCH的结束位置在B＝8个位置中的第5个位置，属于i＝1确定的第5至8个位置的集合中，因此，可确定重复传输的第一个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第2个PDSCH；本公开具体实施例中，假设每个重复传输的PDSCH对应的HARQ-ACK为1比特，则每个重复传输的PDSCH对应的HARQ-ACK对应一个HARQ-ACK反馈位置，则在8个下行传输中，实际存在的HARQ-ACK反馈位置为2个，该重复传输的第一个PDSCH对应于2个HARQ-ACK反馈位置中的第2个位置，参见图4所示；
然后，根据该重复传输的第一个PDSCH对应的HARQ-ACK反馈位置，在第2个HARQ-ACK反馈位置映射反馈信息，此对第1个HARQ-ACK反馈位置映射NACK信息，参见图4所示。
此情况下，若在重复传输的第一个PDSCH之前存在一个PDSCH重复传输，其开始位置不在B＝8个下行传输位置范围中，但最后一次传输在slot n，则该PDSCH的HARQ-ACK由于根据最后一个PDSCH的位置和K1来确定，也是需要在slot n+9中反馈的，因此，在第5至8个位置的集合中结束传输的PDSCH只能映射到第2个HARQ-ACK反馈位置，第1个HARQ-ACK反馈位置是预留给前面可能存在的PDSCH重复传输的。若终端设备在slot n中接收到一个PDSCH重复传输的最后一次传输，则将该PDSCH对应的HARQ-ACK反馈信息映射到第1个HARQ-ACK反馈位置，否则对第1个HARQ-ACK反馈位置映射NACK信息。
此情况下，网络侧比如基站可以按照同样方式确定半静态HARQ-ACK码本的大小以及不同PDSCH重复传输的HARQ-ACK反馈位置，从而从接收到的HARQ-ACK反馈序列中得到每个重复传输的PDSCH对应的HARQ-ACK反馈信息。
本公开另一具体实施例中，假设包含3个HARQ-ACK定时的候选集合K1为{1,3,5}，当然，K1的集合可以有8个值，但其中只包含3个不相同的值，其余值都是重复的，例如K1的集合为{1,3,5,1,3,5,1,3}，这是为了与固定的3比特K1指示域相匹配，但即使此时有8个值，实际有效的仅有3个值即{1,3,5}，可以根据这3个有效值进行后续操作；高层信令预先配置PDSCH进行重复传输，重复传输次数为A＝2，即承载同一个TB的PDSCH需要经过2次重复传输。若以slot为单位进行重复传输，则每次传输在一个包含足够DL或unknown符号的slot中进行，第一个PDSCH传输所在的slot可根据PDCCH的调度确定，例如根据K0确定，PDSCH在一个slot中的时域资源根据PDCCH的调度确定，且重复传输过程中，每个PDSCH在传输slot中的时域位置相同，在第一个slot开始的后续满足上述一个slot中的PDSCH的时域资源分配的slot中进行重复传输。当前不排除具体实现时还可以在slot内部进行重复传输，比如一个PDSCH被分配的符号个数比较少时，而本公开 具体实施例仅以slot为单位进行重复传输。
其中，若第一个重复传输的PDSCH的第一次传输在slot n+3，依次在后续slot n+4重复传输，第二重复传输的PDSCH的第一次传输在slot n+5,依次在后续n+6重复传输，则终端设备进行的相应HARQ-ACK反馈过程为：
首先，根据集合中的最大K1值和最小K1值可以确定slot n+8到slot n+4共计5个slot对应在slot n+9中进行HARQ-ACK传输，其中slot n+8和slot n+7为上行slot，则不能传输下行，被排除在半静态HARQ-ACK码本反馈之外，仅剩slot n+4到slot n+6，对这些slot中的每一个slot都按照现有相关方式确定PDSCH在该slot中可能存在的最大个数，比如此时假设终端能力仅支持每个slot中仅存在一个PDSCH，且每个slot都在根据K0确定的发送调度信令的slot中存在PDCCH监听时机，则确定每个slot都可以包含一个PDSCH传输，即在一个载波上对应在slot n+9中进行HARQ-ACK反馈的下行传输个数为B＝3，或者，直接根据每一个K1值确定的包含可以被调度的下行资源的slot个数作为下行传输个数，或者，根据K1集合中的最大值和最小值确定一个slot集合范围，在这个集合中确定包含可以被调度的下行资源的slot个数作为下行传输个数，都可以得到B＝3，其中，包含可以被调度的下行资源的slot即判断该slot中是否包含预先配置的每个时隙中的下行传输的时域资源分配候选集合中的至少一个下行时域资源，如果包含，则说明该slot中包含足够的下行符号可以被调度进行PDSCH传输；如图5所示；
其次，按照
Figure PCTCN2019079842-appb-000006
即可判断对应在slot n+9中进行HARQ-ACK反馈的3个下行传输位置中实际上只能包含最多2个重复传输次数为2次的PDSCH；此判断的原因为终端设备对重复传输的PDSCH只针对最后一个PDSCH以及K1值确定HARQ-ACK反馈的时域位置，前几个PDSCH重复传输由于属于一个重复传输的PDSCH的中间过程，可不需要进行HARQ-ACK反馈；因此，此种情况下，可确定M＝2，即对应在slot n+9中进行HARQ-ACK反馈的重复传输的PDSCH的个数为2个，对应在slot n+9中进行HARQ-ACK反馈的进行重复传输的下行传输位置仅有2个，只针对此2个下行传输位置进行HARQ-ACK反馈即可，如图5所示；
然后，按照HARQ-ACK映射原则，由于终端设备接收到的在slot n+4结束重复传输的PDSCH的结束位置在B＝3个位置中的第2个位置，属于i＝0确定的第1至2个位置的集合中，即属于B个下行传输中可能存在第一个PDSCH重复传输的范围，因此，可确定重复传输的第一个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第1个重复传输的PDSCH；同理，由于终端设备接收到的在slot n+6结束重复传输的PDSCH的结束位置在B＝3个位置中的第4个位置，属于i＝1确定的第3至4个位置的集合中，即属于B个下行传输中可能存在第二个PDSCH重复传输的范围，因此，可确定重复传输的第二个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第2个重复传输的PDSCH；本公开具体实施例中，假设每个重复传输的PDSCH对应的HARQ-ACK为1比特，则每个重复传输的PDSCH对应的HARQ-ACK对应一个HARQ-ACK反馈位置，则在3个下行传输中，实际存在的HARQ-ACK反馈位置为2个，重复传输的第一个PDSCH对应于2个HARQ-ACK反馈位置中的第1个位置，重复传输的第二个PDSCH对应于2个HARQ-ACK反馈位置中的第2个位置，参见图5所示；
最后，按照上述2个HARQ-ACK位置、重复传输的第一个PDSCH对应的HARQ-ACK反馈位置和重复传输的第二个PDSCH对应的HARQ-ACK反馈位置，生成最终的HARQ-ACK反馈序列。
需指出的是，具体实现时，每个重复传输的PDSCH对应的HARQ-ACK除可为1比特外，还可为多比特，取决于下行传输的具体配置，例如是单TB还是多TB、是否进行空间合并、是否支持CBG传输等。在每个重复传输的PDSCH对应的HARQ-ACK为多比特比如2比特的情况下，当重复传输的第一个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第1个PDSCH，重复传输的第二个PDSCH为对应在slot n+9中进行HARQ-ACK反馈的2个重复传输的PDSCH中的第2个PDSCH时，在8个下行传输中，实际仅存在2个重复传输次数为2的PDSCH，因此只需要对这两个重复传输的PDSCH进行HARQ-ACK反馈，而每个重复传输的PDSCH的HARQ-ACK反馈比特数为2比特，则总的HARQ-ACK反馈比特 数为2x2＝4比特，可以等效为4个HARQ-ACK位置，则重复传输的第一个PDSCH对应于4个HARQ-ACK反馈位置中的第1至2个位置，重复传输的第二个PDSCH对应于4个HARQ-ACK反馈位置中的第3至4个位置，并以此生成最终的HARQ-ACK反馈序列；或者也可以理解为，此时还是2个HARQ-ACK反馈位置，每个HARQ-ACK反馈位置对应2比特HARQ-ACK反馈信息，即重复传输的第一个PDSCH的2比特HARQ-ACK映射为第一个HARQ-ACK反馈位置对应的2比特HARQ-ACK反馈信息，重复传输的第二个PDSCH的2比特HARQ-ACK映射为第二个HARQ-ACK反馈位置对应的2比特HARQ-ACK反馈信息，并以此生成最终的HARQ-ACK反馈序列。
此情况下，网络侧比如基站可以按照同样方式确定半静态HARQ-ACK码本的大小以及不同PDSCH重复传输的HARQ-ACK反馈位置，从而从接收到的HARQ-ACK反馈序列中得到每个重复传输的PDSCH对应的HARQ-ACK反馈信息。
