在第五代(5 th Generation，5G)新空口(New Radio，NR)系统中，支持半持续调度(Semi-Persistent Scheduling，SPS)物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)传输，并且支持一个载波上配置多个SPS配置，一个SPS配置的最小周期可以为1ms。当配置了SPS传输时，高层信令会相应的配置SPS对应的无线网络临时标识(Radio Network Tempory Identity，RNTI)；如配置调度-RNTI(Configured Scheduling-RNTI，CS-RNTI)，用于加扰激活和去激活SPS传输的PDSCH，高层信令还会相应的配置SPS PDSCH的传输周期。当存在业务需要进行SPS传输时，基站可以通过发送指示SPS激活的PDCCH来激活一个SPS配置，指示SPS激活的PDCCH中可以通知这个SPS的调度信息(包括时域、频域资源、调制和编码方案(Modulation and coding scheme，MCS)等信息)，终端按照指示SPS激活的PDCCH以及高层信令预先配置的SPS周期就可以确定周期性的SPS传输机会，在每个周期性的SPS传输机会中进行SPS传输(基站发送、终端接收)。当确定不再需要这个SPS配置或者需要更改SPS配置时，基站可以发送指示下行SPS资源释放的PDCCH(也称SPS PDSCH release)，从而指示对某一个SPS配置释放资源，其中，指示下行SPS资源释放的PDCCH可以一次仅指示一个SPS配置进行资源释放，也可以同时指示多个SPS配置进行资源释放。
5G NR中支持灵活的定时关系。对于具有对应的物理下行控制信道 (Physical Downlink Control CHannel，PDCCH)的PDSCH(即dynamic PDCSH)，承载其调度信息的物理下行控制信道指示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应答(Hybrid automatic repeat request acknowledgement，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(Time Domain Resource Assignment，TDRA)指示PDSCH所在时隙与DCI所在时隙的时隙偏移K0(即调度定时关系)；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(即反馈定时关系)，如图1所示。
调度PDSCH的DCI有两种格式，一种是回退(fall back)DCI格式(如DCI格式1_0)，另一种是非回退(non-fallback)DCI格式(如DCI格式1_1、1_2等)。其中，fallback DCI对应的K1集合固定为{1,2,3,4,5,6,7,8}，non-fallback DCI格式对应的K1集合为系统中定义的最大K1集合(0-16中的整数值)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时间指示域指示一个值给终端，因此该值可以是动态改变的。指示下行SPS资源释放的PDCCH也是需要进行HARQ-ACK反馈的，其反馈时序也是可以由PDCCH中的PDSCH到HARQ-ACK反馈定时指示域进行指示的。对于SPS PDSCH，其K1值也是可以通过指示SPS激活的PDCCH中的PDSCH到HARQ-ACK反馈定时指示域指示的，并且对后续周期性的每一次SPS传输都是用这个K1值确定HARQ-ACK反馈位置。
一个fallback DCI中总是包含3比特PDSCH到HARQ-ACK反馈定时指示域，用于指示取值为1-8的正整数中的一个K1值。一个non-fallback DCI中是否包含PDSCH到HARQ-ACK反馈定时指示域，取决于高层信令预先为终端配置了几个候选K1值。当仅配置了一个K1值时，DCI中不包含PDSCH到HARQ-ACK反馈定时指示域，终端固定使用这一个K1值对需要进行HARQ-ACK反馈的PDSCH、SPS PDSCH、指示下行SPS资源释放的PDCCH确定HARQ-ACK反馈时域位置；当配置了超过1个K1值时，DCI中包含
Figure PCTCN2021087745-appb-000001
比特PDSCH到HARQ-ACK反馈定时指示域，指示PDSCH(包括 被激活的SPS PDSCH)或指示下行SPS资源释放的PDCCH的HARQ-ACK时间。对于传输结束在时隙n的PDSCH或指示下行SPS资源释放的PDCCH，其HARQ-ACK反馈在时隙n+K1中传输，其中，这里的时隙都是参考物理上行控制信道(Physical Uplink Control CHannel，PUCCH)传输所在的载波的子载波间隔(SubCarrier Spacing，SCS)定义的时隙(即PUCCH传输时隙，当DL和UL具有不同的SCS时)，即K1＝0参考点是与PDSCH或指示下行SPS资源释放的PDCCH重叠的最后一个PUCCH传输时隙；上述是以时隙为K1单位的情况，当K1单位为子时隙时，同理。
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 codebook即针对在同一个时域位置(如时隙或子时隙)或同一PUCCH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)产生的HARQ-ACK反馈序列。
Semi-static codebook可以根据K1集合中的HARQ-ACK定时器的值确定每个载波c上对应在同一个时隙(slot)或子时隙(sub-slot)n进行HARQ-ACK反馈的下行传输的位置集合Mc(也可以称为候选PDSCH位置集合)，然后根据Mc即可以确定时隙或子时隙n中传输的HARQ-ACK codebook。具体的，根据每个K1值确定对应的在时隙或子时隙n进行HARQ-ACK反馈的时隙，在这些时隙中的每个时隙中，进一步根据预先配置的下行时域资源分配信息表(即TDRA表格)中的各种时域资源分配信息(即起始和长度指示值(Start and length indicator value，SLIV)，每个SLIV提供了一个下行传输的起始符号和传输长度)，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，当根据一个SLIV确定的在一个时隙中的这个SLIV所指示的符号集合中存在上行符号，则该SLIV不能用作下行传输，因为存在上下行资源冲突，该下行传输实际不会发生，只有满足一个时隙中根据SLIV确定的符号集合中不包含上行符号，例如都为下行和/或灵活(Flexible)符号时，才说明该SLIV对应的下行传输可以在该时隙中存在，其中如果存在SLIV之间的重叠，重叠的SLIV中只会选择一个SLIV调度一个下行传输，而其他SLIV则不可用， 因此根据SLIV重叠的规则，可以从TDRA表格中的所有SLIV中分成多个SLIV组，每个SLIV组认为存在一个下行传输，从而确定出在一个时隙中可能存在的最大的TDM传输的下行传输个数，以此类推，确定出根据K1得到的对应在时隙或子时隙n中进行HARQ-ACK反馈的多个slot中每个slot中的下行传输格式，将多个slot中的总的下行传输个数作为Mc，根据Mc确定在时隙或子时隙n中传输的semi-static HARQ-ACK码本，包括码本的大小和HARQ-ACK具体内容和顺序。
在支持配置多个SPS配置的情况下，不同SPS配置下的SPS PDSCH的HARQ-ACK可以在同一个PUCCH上进行复用传输。考虑到不同的SPS配置由于周期和具体资源分配不同，可能会导致在部分时隙中，存在多个SPS配置对应的SPS PDSCH之间的时域资源存在重叠，而SPS还可以被配置进行重复传输，当被配置进行重复传输的SPS与其他SPS重叠时，如何进行重复传输的SPS的HARQ-ACK反馈还没有明确的方法。

如果在当前时隙中，没有SPS之间的重叠，SPS的个数也不超过终端的接收能力，则这个时隙中的SPS都可以作为对应SPS配置索引j的SPS PDSCH；如果在当前时隙中，存在SPS之间的重叠，但SPS的个数不超过终端的接收 能力，那么对应SPS配置索引j的SPS PDSCH为在重叠的SPS PDSCH中确定的需要接收的SPS PDSCH，即根据上述步骤111-113得到候选SPS PDSCH；如果在当前时隙中，不存在SPS之间的重叠，但SPS的个数超过终端的接收能力，那么对应SPS配置索引j的SPS PDSCH为根据终端的单播PDSCH接收能力确定的需要接收的SPS PDSCH，即根据上述步骤211和/或212得到的SPS PDSCH；如果在当前时隙中，既存在SPS之间的重叠，且SPS的个数也超过终端的接收能力，那么对应SPS配置索引j的SPS PDSCH为：在重叠的SPS PDSCH中确定的需要接收的SPS PDSCH中，进一步根据终端的单播PDSCH接收能力确定的需要接收的SPS PDSCH，即上述两种方式都执行之后得到的SPS PDSCH。
本公开的上述实施例中，重复传输的SPS PDSCH的HARQ-ACK为K次重复传输中，到所述目标SPS PDSCH为止的重复传输的SPS PDSCH合并之后得到的HARQ-ACK。即如果配置SPS PDSCH的重复传输次数为K次，如果所述目标SPS PDSCH为其中的K-1次，那么重复传输的SPS PDSCH的HARQ-ACK为K-1SPS PDSCH传输机会中接收到的SPS PDSCH合并之后得到的HARQ-ACK，即为重复传输实际的HARQ-ACK。
本公开的上述实施例中，重复传输的SPS PDSCH的HARQ-ACK映射到HARQ-ACK传输所在的时间单元中的对应于SPS PDSCH的HARQ-ACK码本中的对应于所述目标SPS PDSCH传输所在的时隙的HARQ-ACK位置。即如果根据K1集合＝{1,2,3,4}确定时隙n、n+1、n+2、n+3都需要在时隙n+4中的同一个HARQ-ACK码本中进行SPS PDSCH的HARQ-ACK反馈，如果对应SPS配置1的SPS PDSCH为在时隙n、n+1、n+2、n+3中进行4次重复传输的SPS，且确定4次重复传输中的目标SPS PDSCH为时隙n+2中的SPS PDSCH，时隙n、n+1和n+3中分别存在对应其他SPS配置的SPS PDSCH传输也需要在时隙n+4中的同一个HARQ-ACK码本重传输HARQ-ACK，则时隙n+4中的HARQ-ACK码本是需要对时隙n、n+1、n+2和n+3都预留HARQ-ACK反馈位置的，对于对应SPS配置1的进行4次重复传输的SPS PDSCH，虽然时隙n、n+1、n+3中也包含这个SPS PDSCH的传输机会，但由于目标SPS PDSCH是时隙n+2中的SPS PDSCH，则重复传输的SPS配置 1的SPS PDSCH的HARQ-ACK是映射到时隙n+4中的HARQ-ACK码本中对应于时隙n+2的HARQ-ACK位置，即如果时隙n到n+3中每个时隙对应1比特HARQ-ACK，HARQ-ACK码本包括4比特HARQ-ACK，从第一比特到最后一比特分别对应时隙n到时隙n+3中的每一个时隙(即第1比特对应时隙n，第2比特对应时隙n+1，第3比特对应时隙n+2，第4比特对应时隙n+3)，则重复传输的SPS配置1的SPS PDSCH的HARQ-ACK是映射到HARQ-ACK码本中的第3比特HARQ-ACK的位置的。
本公开的上述实施例中，如果所述目标SPS PDSCH传输所在的时隙中包含多个HARQ-ACK位置，重复传输的SPS PDSCH的HARQ-ACK映射到HARQ-ACK码本中与所述目标SPS PDSCH对应的HARQ-ACK位置；其中与所述目标SPS PDSCH对应的HARQ-ACK位置即：根据所述目标SPS PDSCH对应的SPS配置索引确定的HARQ-ACK位置，其中，所述时隙对应的多个HARQ-ACK位置是按照该时隙中的多个SPS PDSCH对应的SPS配置索引的从小到大或者从大到小顺序排列的。即如果根据K1集合＝{1,2,3,4}确定时隙n、n+1、n+2、n+3都需要在时隙n+4中的同一个HARQ-ACK码本中进行SPS PDSCH的HARQ-ACK反馈，如果对应SPS配置1的SPS PDSCH为在时隙n、n+1、n+2、n+3中进行4次重复传输的SPS，且确定4次重复传输中的目标SPS PDSCH为时隙n+2中的SPS PDSCH，时隙n、n+1和n+3中分别存在对应其他SPS配置的SPS PDSCH传输也需要在时隙n+4中的同一个HARQ-ACK码本重传输HARQ-ACK，则时隙n+4中的HARQ-ACK码本是需要对时隙n、n+1、n+2和n+3都预留HARQ-ACK反馈位置的，对于对应SPS配置1的进行4次重复传输的SPS PDSCH，虽然时隙n、n+1、n+3中也包含这个SPS PDSCH的传输机会，但由于目标SPS PDSCH是时隙n+2中的SPS PDSCH，则重复传输的SPS配置1的SPS PDSCH的HARQ-ACK是映射到时隙n+4中的HARQ-ACK码本中对应于时隙n+2的HARQ-ACK位置，即如果假设时隙n到n+3中每个时隙对应2比特HARQ-ACK(即每个时隙中都包含2个可能的下行传输位置，即有两组SLIV)，HARQ-ACK码本包括8比特HARQ-ACK，从第一比特到最后一比特每2比特分别对应时隙n到时隙n+3中的每一个时隙(即第1、2比特对应时隙n，第3、4比特对应时 隙n+1，第5、6比特对应时隙n+2，第7、8比特对应时隙n+3)，则如果假设目标SPS PDSCH对应的SLIV在时隙n+2中的两个SLIV组中对应的是第一个SLIV组(即两个可能的下行传输位置中对应第一个下行传输位置)，则重复传输的SPS配置1的SPS PDSCH的HARQ-ACK是映射到HARQ-ACK码本中的第5比特HARQ-ACK的位置的，如果假设目标SPS PDSCH对应的SLIV在时隙n+2中的两个SLIV组中对应的是第2个SLIV组(即两个可能的下行传输位置中对应第2个下行传输位置)，则重复传输的SPS配置1的SPS PDSCH的HARQ-ACK是映射到HARQ-ACK码本中的第6比特HARQ-ACK的位置的。
本公开的上述实施例中，对于所述重复传输的SPS PDSCH中不是所述目标SPS PDSCH的SPS PDSCH,不进行HARQ-ACK反馈。即如果根据K1集合＝{1,2,3,4}确定时隙n、n+1、n+2、n+3都需要在时隙n+4中的同一个HARQ-ACK码本中进行SPS PDSCH的HARQ-ACK反馈，如果对应SPS配置1的SPS PDSCH为在时隙n、n+1、n+2、n+3中进行4次重复传输的SPS，且确定4次重复传输中的目标SPS PDSCH为时隙n+2中的SPS PDSCH，时隙n、n+1和n+3中分别存在对应其他SPS配置的SPS PDSCH传输也需要在时隙n+4中的同一个HARQ-ACK码本重传输HARQ-ACK，则时隙n+4中的HARQ-ACK码本是需要对时隙n、n+1、n+2和n+3都预留HARQ-ACK反馈位置的，对于对应SPS配置1的进行4次重复传输的SPS PDSCH，虽然时隙n、n+1、n+3中也包含这个SPS PDSCH的传输机会，但在HARQ-ACK码本中，并不需要对这些SPS PDSCH传输机会预留HARQ-ACK反馈的位置，因为并不需要对这些SPS PDSCH反馈HARQ-ACK。
本公开的上述实施例中，当满足如下条件的至少一个时，可以执行上述步骤21和22来确定目标SPS PDSCH并基于目标SPS PDSCH确定HARQ-ACK传输的时间单元(即如果不满足下述条件，可以不采用本公开的方式确定重复传输的SPS PDSCH的HARQ-ACK传输的时间单元；当然，也不排除不需要进行下述条件的判断，对任何SPS传输情况，总是使用本公开的方式确定重复传输的SPS PDSCH的HARQ-ACK传输的时间单元)：
当配置了重复传输的SPS PDSCH在重复传输的时隙中的至少一个时隙 或最后一个时隙中与其他SPS PDSCH存在时域重叠；
当配置了重复传输且对应SPS配置索引i的SPS PDSCH，在重复传输的时隙中的至少一个时隙或最后一个时隙中与对应SPS配置索引j的SPS PDSCH存在时域重叠；
在传输HARQ-ACK的时间单元中，仅存在对应SPS PDSCH的HARQ-ACK传输，或，在配置使用动态HARQ-ACK码本时，对应SPS PDSCH的HARQ-ACK，与对应具有DCI调度的PDSCH或指示下行SPS资源释放的PDCCH的HARQ-ACK进行复用传输。
本公开的一可选的实施例中，对于配置了重复传输的对应半持续调度SPS配置索引i的半持续调度物理下行共享信道SPS PDSCH，确定所述SPS PDSCH重复传输中的一个目标SPS PDSCH，包括以下至少一项：
1)当配置了重复传输的SPS PDSCH在重复传输的时隙中的至少一个时隙或最后一个时隙中与其他SPS PDSCH存在时域重叠时，对于配置了重复传输的对应半持续调度SPS配置索引i的半持续调度物理下行共享信道SPS PDSCH，确定所述SPS PDSCH重复传输中的一个目标SPS PDSCH；
2)当配置了重复传输且对应SPS配置索引i的SPS PDSCH，在重复传输的时隙中的至少一个时隙或最后一个时隙中与对应SPS配置索引j的SPS PDSCH存在时域重叠时，对于配置了重复传输的对应半持续调度SPS配置索引i的半持续调度物理下行共享信道SPS PDSCH，确定所述SPS PDSCH重复传输中的一个目标SPS PDSCH；
3)在传输HARQ-ACK的时间单元中，仅存在对应SPS PDSCH的HARQ-ACK传输，或，在配置使用动态HARQ-ACK码本时，对应SPS PDSCH的HARQ-ACK，与对应具有下行控制信息DCI调度的PDSCH或指示下行SPS资源释放的PDCCH的HARQ-ACK进行复用传输时，对于配置了重复传输的对应半持续调度SPS配置索引i的半持续调度物理下行共享信道SPS PDSCH，确定所述SPS PDSCH重复传输中的一个目标SPS PDSCH。
具体实现时，如以下实施例1：如图3所示，时隙n到n+3为对应SPS配置4的SPS PDSCH进行K＝4次重复传输的时隙，其中重复传输的最后一个时隙(即时隙n+3)中对应SPS配置4(即i＝4)的SPS PDSCH与对应SPS 配置3(即j＝3)的SPS PDSCH在时域上存在资源重叠，而在时隙n+2中，对应SPS配置4的SPS PDSCH在时域上不与任何其他SPS PDSCH存在重叠，则根据本公开方法，对于采用重复传输的对应SPS配置4的SPS PDSCH，在4次重复传输中是基于时隙n+2中的SPS PDSCH(即目标SPS PDSCH)以及SPS配置对应的K1值，确定重复传输的SPS配置4的SPS PDSCH的HARQ-ACK反馈传输所在的时隙的，即基于时隙n+2中的对应SPS配置4的SPS PDSCH的结束为止找到与之重叠的传输PUCCH的UL时隙(即根据UL的SCS划分的时隙)，本实施例中，由于UL和DL的SCS相同，因此UL和DL的时隙划分是对齐的，因此找到的是UL时隙n+2，以UL时隙n+2作为K1＝0时的参考点(即UL时隙n+2即为K1＝0是对应的UL时隙)，可以得到K1＝1时对应的UL时隙n+3，从而确定重复传输的对应SPS配置4的SPS PDSCH的HARQ-ACK反馈是在时隙n+3中传输，其中HARQ-ACK是时隙n、n+1和n+2中重复传输的3次SPS PDSCH的信息合并之后译码得到的HARQ-ACK(即这个HARQ-ACK是用来表示重复传输中，到用于确定HARQ-ACK反馈位置的SPS PDSCH位置的所有重复的SPS PDSCH合并之后的有效HARQ-ACK，从而体现出重复传输的增益)，从而避免了按照相关技术根据4次重复传输中的第4次重复传输以及K1确定HARQ-ACK的传输时隙中，由于第4次重复传输(即时隙n+3中的传输)与另一个对应SPS配置索引编号更低的SPS PDSCH存在时域资源重叠，而导致在反馈传输的时隙n+4中的HARQ-ACK码本中并包含对应SPS配置4的SPS PDSCH的HARQ-ACK传输，从而导致对应SPS配置4的SPS PDSCH的HARQ-ACK不能上报的问题。其中，时隙n+3中的SPS HARQ-ACK码本中，不需要包含时隙n和n+1中对应SPS配置4的SPS PDSCH的HARQ-ACK，即即使此时K1集合＝{1,2,3}，即根据K1集合的范围，基于时隙n+3，可以推断出时隙n、n+1和n+2中都可能存在SPS可以在时隙n+3中进行HARQ-ACK反馈，但如果时隙n和n+1中仅包含重复传输的SPS PDSCH中不是用来确定反馈时的目标SPS PDSCH，则由于重复传输的多个SPS PDSCH最终的HARQ-ACK已经在用来确定反馈时的目标SPS PDSCH对应的HARQ-ACK位置上传输了，则同一个HARQ-ACK码本中就不需要对其他不是目标SPS PDSCH的SPS  PDSCH预留HARQ-ACK反馈位置了，即在假设K1集合＝{1,2,3}时，时隙n+3中的SPS HARQ-ACK码本中对应于图3的情况，仅包含对应时隙n+2中的SPS配置4的SPS PDSCH的1比特HARQ-ACK反馈就够了。当然，也不排除时隙n+3中的SPS HARQ-ACK码本可以对根据K1set确定的可能在时隙n+3中进行HARQ-ACK反馈的所有时隙中的重复传输的SPS PDSCH都预留HARQ-ACK，则对应于图3情况，时隙n+3中的SPS HARQ-ACK码本可以包含3比特HARQ-ACK，分别对应于时隙n、n+1和n+2中的对应SPS配置4的SPS PDSCH，但这样就会存在一定的冗余(实际上时隙n和n+1中的SPS PDSCH的HARQ-ACK没必要反馈)。
本公开的一可选的实施例中，混合自动重传应答消息的传输资源的确定方法还可以包括：对于所述重复传输的SPS PDSCH中不是所述目标SPS PDSCH的SPS PDSCH，不进行HARQ-ACK反馈。
具体实现实例如下实施例2：
类似上述实施例1，所不同的是假设时隙n+2中还存在一个对应SPS配置5的SPS PDSCH传输与对应SPS配置4的SPS PDSCH在时域上存在重叠，如图4所示，则类似实施例1中的情况，对于采用重复传输的对应SPS配置4的SPS PDSCH，在4次重复传输中是基于时隙n+2中的SPS PDSCH(即目标SPS PDSCH)以及SPS配置对应的K1值，确定重复传输的SPS配置4的SPS PDSCH的HARQ-ACK反馈传输所在的时隙的，即基于时隙n+2中的对应SPS配置4的SPS PDSCH的结束为止找到与之重叠的根据传输PUCCH的SCS确定的最后一个UL时隙；这是因为，虽然时隙n+2中存在一个与对应SPS配置4的SPS PDSCH重叠的SPS PDSCH，但由于这个SPS PDSCH对应的SPS配置的索引是5，比SPS配置4的索引大，因此对应SPS配置5的SPS PDSCH是会被对应SPS配置4的SPS PDSCH所停止的，即在这样的时域重叠下，是对应SPS配置5的SPS PDSCH不会传输也不会反馈HARQ-ACK，并不影响时隙n+2中的对应SPS配置4的SPS PDSCH，所以得到的配置4的SPS PDSCH的HARQ-ACK传输时隙的结果是同实施例1的，不再赘述。
实施例3：
类似上述实施例1，所不同的是假设时隙n+2中存在多个SPS之间的相 互重叠，如图5所示，则类似实施例1中的情况，对于采用重复传输的对应SPS配置4的SPS PDSCH，在4次重复传输中是基于时隙n+2中的SPS PDSCH(即目标SPS PDSCH)以及SPS配置对应的K1值，确定重复传输的SPS配置4的SPS PDSCH的HARQ-ACK反馈传输所在的时隙的，即基于时隙n+2中的对应SPS配置4的SPS PDSCH的结束为止找到与之重叠的根据传输PUCCH的SCS确定的最后一个UL时隙；这是因为，虽然时隙n+2中存在对应配置2的SPS PDSCH，但由于这个对应配置2的SPS PDSCH与对应配置1的SPS重叠，则这个对应配置2的SPS PDSCH实际上根据SPS之间的重叠规则，并不属于终端需要接收的SPS PDSCH，因此并不需要考虑这个SPS PDSCH与重复传输的对应配置4的SPS PDSCH之间的重叠，那么在时隙n+2中，就不存在一个对应比编号4小的SPS配置的SPS PDSCH与对应SPS配置2的SPS PDSCH重叠，从而可以确定时隙n+3中的对应SPS配置2的SPS PDSCH即为最后一个满足条件的SPS PDSCH(即目标SPS PDSCH)，从而得到的HARQ-ACK传输时隙的结果是同实施例1的，不再赘述。
上述实施例中仅以UL和DL的SCS相同、单载波的情况为例，SCS不同、多载波聚合等情况下同样适用；上述实施例中仅以时隙为单位的传输为了，当K1的单位为子时隙或者其他预定的时间单元长度时，同样适用；上述实施例中，在时隙n+3中，是否存在对应SPS配置1的SPS PDSCH传输并不影响本实施例的判断结果，因为这个SPS配置对应的SPS PDSCH的时域资源并不与对应SPS配置4的SPS PDSCH以及其他SPS PDSCH的时域资源重叠。
本公开的上述实施例中，当SPS PDSCH进行重复传输时，根据K次重复传输中的最后一次不与对应SPS配置索引j的SPS PDSCH存在时域重叠的SPS PDSCH，确定重复传输的SPS PDSCH的HARQ-ACK传输所在的时间单元。保证PDSCH重复传输时可以正常的进行HARQ-ACK反馈，避免按照重复传输中的最后一次传输确定反馈时序时，由于重复传输的SPS PDSCH与其他SPS PDSCH的冲突导致这个重复传输的SPS PDSCH无法进行HARQ-ACK反馈。
