本申请要求在2019年11月08日提交中国专利局、申请号为201911089349.6、申请名称为“SPS PDSCH的HARQ反馈方法、装置及存储介质”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
本发明涉及通信技术领域，尤其涉及一种SPS PDSCH的HARQ反馈方法、装置及存储介质。
背景技术
目前，在第五代移动通信技术(5th generation mobile networks或5th generation wireless systems或5th-Generation，5G)系统中，终端可以将上行混合自动重传请求确认(Hybrid Automatic Repeat Request，HARQ-ACK)信息通过物理上行链路控制信道(Physical Uplink Control CHannel，PUCCH)传输至基站。在5G新空口(New Radio，NR)Rel-15版本中，一个PUCCH中仅允许传输一个半持续调度(Semi-Persistent Scheduling，SPS)物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)的HARQ-ACK反馈信息。
相较于NR Rel-15而言，NR Rel-16中可以支持更短的SPS PDSCH传输周期，新的周期可能会小于或者等于1个时隙。将支持一个PUCCH中传输多个SPS PDSCH的HARQ-ACK反馈信息。对于时分双工(Time Division Duplexing，TDD)场景，由于在一个SPS PDSCH配置下，SPS PDSCH传输的位置和对应的HARQ-ACK反馈位置之间的时隙偏移是通过激活下行控制信息(Downlink Control Information，DCI)指示的，而激活DCI中仅能指示一个时隙偏移值，因此可能存在有些SPS PDSCH对应的HARQ-ACK反馈使用的PUCCH资源和基站指示的下行符号冲突的情况，这时终端无法传输对应 的HARQ-ACK反馈信息，从而可能导致短周期SPS PDSCH传输的HARQ反馈被过多的丢弃。

在本申请实施例中，终端可以接收网络侧设备通过高层信令配置的PDSCH传输的位置和对应的HARQ-ACK反馈位置之间的时隙偏移K值集合，该K值集合中包括至少一个K值，进而可以接收到网络侧设备发送的用于激活所述SPS PDSCH传输的下行控制信息DCI，该DCI用于指示K值集合中的第一K值，进而当该第一K值指示的时隙中与SPS PDSCH传输对应的PUCCH资源被确定为无效PUCCH资源时，可以将SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至K值集合中的第二K值指示的时隙进行反馈。也就是说，在将SPS PDSCH传输对应的HARQ-ACK反馈信息延迟到第一K值指示的时隙中进行反馈后，若第一K值指示的时隙中没有有效的PUCCH资源，则可以继续将该HARQ-ACK反馈信息延迟到K集合中的其他K值能够指示的时隙中进行反馈，这样可以使得SPS PDSCH传输对应的HARQ-ACK反馈信息更好的被上传到网络侧设备，从而减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题，从而提升SPS PDSCH传输的传输性能。
并且，当延迟后的时隙中还存在动态PDSCH的HARQ-ACK反馈信息时，可以在不改变反馈码本的基础上进行SPS PDSCH传输对应的HARQ-ACK反 馈信息的反馈，因此可以进一步地减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题。

(1)网络侧设备，是一种为终端提供无线通信功能的设备，包括但不限于：5G中的基站(gNB)、无线网络控制器(radio network controller，RNC)、节点B(node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved nodeB，或home node B，HNB)、基带单元(Base Band Unit，BBU)、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、移动交换中心等。本申请中的基站还可以是未来可能出现的其他通信系统中为所述终端提供无线通信功能的设备。
(2)终端，是一种可以向用户提供语音和/或数据连通性的设备。例如，终端设备包括具有无线连接功能的手持式设备、车载设备等。目前，终端设备可以是：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(selfdriving)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端，或智慧家庭(smart home)中的无线终端等。
在5G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)传输以及具有对应的物理下行控制信道(Physical Downlink Control CHannel，PDCCH)的PDSCH(即dynamic PDCSH)传输。当配置了SPS PDSCH业务时，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)，用于加扰针对SPS PDSCH的PDCCH，高层信令还可以相应的配置SPS PDSCH的传输间隔。
进而，高层信令预先为终端配置N个候选HARQ-ACK timing值(即SPS PDSCH传输的位置和对应的HARQ-ACK反馈位置之间的时隙偏移值K)，其 中N的取值范围为1至8。具有PDCCH的PDSCH的HARQ-ACK timing由PDCCH中的
Figure PCTCN2020119305-appb-000001
比特HARQ-ACK timing指示域指示高层信令预先配置的N个值中的任意一个。
对于SPS PDSCH传输，由于不存在对应的PDCCH，因此SPS PDSCH传输对应的HARQ-ACK timing，由激活SPS PDSCH传输的PDCCH中的HARQ-ACK timing指示域确定，在SPS PDSCH传输过程中使用相同的HARQ-ACK timing值。对于具有PDCCH的PDSCH传输，其HARQ-ACK反馈使用的PUCCH资源根据PDCCH中的PUCCH资源指示(PRI,PUCCH Resource Indication)信息域确定。高层信令预先为终端配置8～16个候选PUCCH资源，并通过PDCCH中3比特PRI指示(当配置的PUCCH资源个数大于8时，需要结合PDCCH的CCE index确定)终端使用其中一个。
对于SPS PDSCH传输，如果对应的HARQ-ACK和具有PDCCH的PDSCH传输对应的HARQ-ACK在同一个时隙中反馈，则复用在具有PDCCH的PDSCH对应的PUCCH资源上进行传输。如果一个时隙中只有SPS PDSCH传输对应的HARQ-ACK反馈，由于不存在对应的PDCCH，因此无法使用PDCCH中的PRI确定使用的PUCCH资源。NR Rel-15协议中规定通过高层信令对SPS PDSCH配置专属的PUCCH资源，可以使用PUCCH格式0或者PUCCH格式1，因此SPS PDSCH专属的PUCCH资源最大支持2比特的HARQ-ACK反馈。在Rel-16中，当多配置的SPS PDSCH的HARQ-ACK复用传输时，网络侧可以通过高层信令对SPS PDSCH配置多个专属的PUCCH资源，可以使用PUCCH格式0、PUCCH格式1、PUCCH格式2、PUCCH格式3或者PUCCH格式4，可以支持1～1706比特数的反馈。
当仅配置了一个SPS PDSCH传输时，如果终端仅收到一个SPS PDSCH传输，则在其对应的专属PUCCH资源上进行反馈。然而，由于在NR Rel-16会定义更短的SPS PDSCH传输周期，因此基站无法保证SPS PDSCH的HARQ-ACK反馈信息使用的PUCCH资源不和TDD的下行符号冲突，而终端也不能在TDD的下行符号中传输SPS PDSCH的HARQ-ACK反馈，因此 会导致短周期SPS PDSCH传输的HARQ反馈被过多的丢弃。
具体的，请参考图1，其中，假设SPS PDSCH的传输周期为1个时隙，时隙偏移K值集合(即图1中的K set)为{1，2}。若激活DCI中指示的K值为2，则时隙n中SPS PDSCH的HARQ-ACK反馈信息需要在时隙n+2传输，然而时隙n+2为下行时隙，UE需要丢弃时隙n+2中的HARQ-ACK反馈信息。其中，Semi DL symbols为半静态配置下行符号；Semi FL symbols为半静态配置灵活传输符号，该符号对应处既可以用于上行传输，又可以用于下行传输；Semi UL symbols半静态配置上行符号。
进一步地，如果仅是将SPS PDSCH传输对应的HARQ-ACK反馈延迟到与半静态配置的下行符号不冲突的时隙进行反馈，可能出现的另一个问题：即当延迟后的时隙中还存在动态PDSCH的HARQ-ACK反馈信息时，如果基于现有的复用反馈方案确定反馈码本，码本中只能包含时隙偏移K对应的时隙，不能包含时隙偏移K对应的时隙之外的时隙，然而SPS PDSCH传输的位置和对应的延迟后的HARQ-ACK反馈所在时隙的间隔可能超过配置的时隙偏移值中最大的值，因此根据现有技术确定的反馈码本不能包括该SPS PDSCH传输的反馈信息，若不改变反馈码本，则无法上传SPS PDSCH传输对应的HARQ-ACK反馈信息。
有鉴于此，本发明实施例提供了一种SPS PDSCH的HARQ反馈方案。在该方案中，终端可以接收网络侧设备通过高层信令配置的PDSCH传输的位置和对应的HARQ-ACK反馈位置之间的时隙偏移K值集合，该K值集合中包括至少一个K值，进而在根据接收的DCI，将SPS PDSCH传输对应的HARQ-ACK反馈信息延迟到第一K值指示的时隙中进行反馈后，若第一K值指示的时隙中没有有效的PUCCH资源，则可以继续将该HARQ-ACK反馈信息延迟到K集合中的其他K值能够指示的时隙中进行反馈。这样可以使得SPS PDSCH传输对应的HARQ-ACK反馈信息更好的被上传到网络侧设备，从而减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题，或者还可能避免丢弃SPS PDSCH 传输对应的HARQ-ACK反馈信息，从而提升SPS PDSCH传输的传输性能。
并且，当延迟后的时隙中还存在动态PDSCH的HARQ-ACK反馈信息时，可以在不改变反馈码本的基础上进行SPS PDSCH传输对应的HARQ-ACK反馈信息的反馈，因此可以进一步地减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题。
为进一步说明本申请实施例提供的通话控制的方案，下面结合附图以及具体实施方式对此进行详细的说明。虽然本申请实施例提供了如下述实施例或附图所示的方法操作步骤，但基于常规或者无需创造性的劳动在所述方法中可以包括更多或者更少的操作步骤。在逻辑上不存在必要因果关系的步骤中，这些步骤的执行顺序不限于本申请实施例提供的执行顺序。
请参考图2，图2为本申请实施例提供的一种SPS PDSCH的HARQ反馈的流程图，具体描述如下：
步骤201：网络侧设备通过高层信令配置的PDSCH传输的位置和对应的HARQ-ACK反馈位置之间的时隙偏移K值集合，并将配置的K值集合发送给终端，则终端可以接收到该K值集合。
在本申请实施例中，由于TDD场景收发共用一个频点，上行链路和下行链路需要使用不同的时隙来进行通信，因此PDSCH传输和其对应的HARQ-ACK反馈之间存在一定时隙差。从而，网络侧设备可以根据PDSCH传输的时隙，为PDSCH传输对应的HARQ-ACK反馈信息配置至少一个用于进行HARQ-ACK反馈的时隙偏移K值，进而可以将配置至少一个K值组成的K值集合发送给终端。
进一步地，由于现有通信协议中，网络侧设备为SPS PDSCH传输和PDSCH传输对应的时隙偏移K值集合是相同的，因此，在进行SPS PDSCH传输对应的HARQ-ACK消息反馈时，也可以使用为PDSCH传输配置的时隙偏移K值集合中的K值。
步骤202：网络侧向终端发送用于激活SPS PDSCH传输的下行控制信息DCI，则终端可以接收到该下行控制信息DCI，其中，该DCI中指示有K值 集合中的第一K值。
在本申请实施例中，网络侧设备可以通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)向终端发送用于激活SPS PDSCH传输的DCI，并可以在DCI中指示用于反馈SPS PDSCH传输对应的HARQ-ACK反馈的第一K值，该第一K值为前述K值集合中的任意一个K值。例如，可以是K值集合中最小的K值，这样可以较快的进行SPS PDSCH传输对应的HARQ-ACK反馈，减小HARQ-ACK反馈的时延。
进一步地，终端在接收该DCI后，可以DCI激活SPS PDSCH传输，并可以根据接收的DCI中指示的第一K值，确定用于反馈SPS PDSCH传输对应的HARQ-ACK反馈信息的时隙，进而，终端可以在该时隙中向网络侧设发送HARQ-ACK反馈信息。
步骤203：终端确定第一K值指示的时隙中与所述SPS PDSCH传输对应的物理上行控制链路PUCCH资源是否为无效PUCCH资源，若否，则执行步骤204，若是，则执行步骤205。
在本申请实施例中，网络侧设备一般可以给终端配置1～4个PUCCH资源集，在通过DCI指示终端上传HARQ-ACK反馈信息时，网络侧设备可以先基于待传HARQ-ACK反馈信息等上行控制信息的数据量(如，比特数)确定需要选择的PUCCH资源集，并通过DCI中的PUCCH资源指示(PUCCH resource indicator)字段指示PUCCH资源集的一个PUCCH资源。也就是说，终端在接收到网络侧设备发送的DCI后，可以根据DCI中指示的第一K值确定出该第一K值对应的时隙，以及用于在该时隙中传输SPS PDSCH传输对应的HARQ-ACK反馈信息的PUCCH资源。
进而，终端可以根据确定出的PUCCH资源所占用的OFMD符号，确定出该时隙中与SPS PDSCH传输对应的PUCCH资源是否为无效PUCCH资源，以便于终端及时确定出第一K值指示的时隙是否可以用于反馈SPS PDSCH传输对应的HARQ-ACK反馈信息。
具体的，本申请实施例中可以按照但不限于按照以下几种方式确定SPS  PDSCH传输对应的PUCCH资源为无效PUCCH资源。
第一种，确定SPS PDSCH传输对应的PUCCH资源中至少一个符号为半静态配置的下行符号。例如，所述SPS PDSCH传输对应的PUCCH资源包含8个符号，如果基站通过RRC信令配置指示其中的一个符号或多个符号为下行符号时，则认为所述SPS PDSCH传输对应的PUCCH资源为无效PUCCH资源。
第二种，SPS PDSCH传输对应的PUCCH资源中至少一个符号为需要用于保护间隔时段GP的符号。
第三种，SPS PDSCH传输对应的PUCCH资源中至少一个符号为动态指示的下行符号。
第四种，SPS PDSCH传输对应的PUCCH资源中至少一个符号为动态指示的灵活符号。
其中，该动态指示的灵活符号可以是时隙格式指示(Slot Format indication，SFI)指示的灵活符号，也可以是DCI调度的下行传输所占用的符号。
步骤204：终端通过PUCCH资源向网络侧设备反馈SPS PDSCH传输对应HARQ-ACK反馈信息。
在本申请实施例中，当第一K值指示的时隙中与SPS PDSCH传输对应的PUCCH资源为有效PUCCH资源，终端则可以通过该PUCCH资源向网络侧设备上传该SPS PDSCH传输对应的HARQ-ACK反馈信息，从而完成SPS PDSCH传输对应的HARQ-ACK反馈信息的反馈。
步骤205：将该SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至K值集合中的第二K值所指示的时隙进行反馈。
在本申请实施例中，当确定出第一K值指示的时隙中没有有效的PUCCH资源时，可以将SPS PDSCH传输对应的HARQ-ACK反馈信息延迟到K值集合中的第二K值所指示的时隙进行反馈，从而这样可以使得SPS PDSCH传输对应的HARQ-ACK反馈信息更好的被上传到网络侧设备，从而减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS  PDSCH传输性能下降的问题，从而提升SPS PDSCH传输的传输性能。
其中，第二K值可以是K值集合中除第一K值以外的其他K值，例如，终端可以将K值集合中的K值按照从小到大的顺序进行排序，若第一K值可以为K值集合中最小K值，则第二K值可以是排在第一K值的下一个K值(即排序第2的K值)，进而可以将SPS PDSCH对应的HARQ-ACK反馈信息延迟至第一K值的下一个K值所指示的时隙进行反馈，因此，相较于相关技术中，在第一K值指示的时隙中没有包含有效的PUCCH资源，直接将SPS PDSCH对应的HARQ-ACK反馈信息丢弃而言，可以降低HARQ-ACK反馈信息被丢弃的可能，或者避免丢弃HARQ-ACK反馈信息，从而减小HARQ-ACK反馈信息被丢弃造成的问题。并且，由于第二K值是第一K值的下一个K值，两者之间的时隙差较小，若第二K值中完成了SPS PDSCH对应的HARQ-ACK反馈信息的上传，还可以减小HARQ-ACK反馈的时延，从而提高SPS PDSCH传输的传输性能。
在本申请实施例中，在将SPS PDSCH对应的HARQ-ACK反馈信息延迟至第一K值的下一个K值所指示的时隙进行反馈后，是否能够在该下一个K值指示的时隙中完成SPS PDSCH对应的HARQ-ACK反馈信息的上传，还需要根据该下一个K值指示的时隙中SPS PDSCH对应的PUCCH资源是否为有效的PUCCH资源来确定。若该下一个K值指示的时隙中包含有效的PUCCH资源，则可以在下一个K值指示的时隙中传输SPS PDSCH传输对应的HARQ-ACK反馈信息。若下一个K值对应的时隙中未包含有效的PUCCH资源，则可以丢弃该SPS PDSCH传输对应的HARQ-ACK反馈信息；或者，还可以将该SPS PDSCH传输对应的HARQ-ACK反馈信息按照前述K值集合中K值的排列顺序依次延迟，直至延迟到K值集合中的最后一个K值指示的时隙中仍未包括有效的PUCCH资源时，则丢弃该SPS PDSCH传输对应的HARQ-ACK反馈信息。这样可以使得SPS PDSCH传输对应的HARQ-ACK反馈信息更好的被上传到网络侧设备，从而减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的 问题，以提高SPS PDSCH传输的传输性能。
下面以K值集合中的K值按照从小到大的顺序进行排序，且第二K为第一K值的下一个K值为例，对本申请实施例中将SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至下一个K值指示的时隙进行反馈的实施方式进行具体说明。
实施方式1
请参考图3，在本实施例中，假设网络侧设备为终端配置的SPS PDSCH传输的周期为1个时隙，配置的K值集合为{2，4}。
其中，网络侧设备下发给终端的用于激活时隙n中SPS PDSCH传输的DCI中指示的K值为2，则时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息可以在时隙n+2中反馈，由于时隙n+2为下行时隙，所以SPS PDSCH传输对应的PUCCH资源为无效的PUCCH资源。
进而，可以将时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至下一个K值指示的时隙进行反馈。从配置的K值集合中可以确定下一个K值为4，其指示的时隙为时隙n+4，即可以将时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至时隙n+4中进行反馈，若时隙n+4中包括有效的PUCCK资源，则可以将时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息通过该有效的PUCCH资源上传给网络侧设备，否则可能将时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息丢弃。
这样，当终端不能在时隙n+2中向网络侧设反馈时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息时，可以延迟至n+4(即下一个K值指示的时隙)中进行反馈，因此可以使得SPS PDSCH传输对应的HARQ-ACK反馈信息更好的被上传到网络侧设备，从而减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题，提高SPS PDSCH传输的传输性能。
进一步地，在本申请实施例中，由于时隙n+2中的SPS PDSCH传输对应的HARQ-ACK反馈信息可以在n+4中反馈，那么时隙n+4中SPS PDSCH传 输对应的PUCCH资源可以同时承载时隙n和时隙n+2中的SPS PDSCH传输对应的HARQ-ACK反馈信息。当一个时隙同时承载其他两个时隙中SPS PDSCH传输的HARQ-ACK反馈信息时，该一个时隙如何进行HARQ-ACK反馈请参见下文中实施方式2中相关的描述，此处不再赘述。
相应的，时隙n+1中SPS PDSCH传输对应的HARQ-ACK反馈信息，以及时隙n+2中SPS PDSCH传输对应的HARQ-ACK反馈信息也可以按照前述的方式进行上传或者丢弃，此处不再一一介绍。
实施方式2
请参考图4，在本实施例中，假设网络侧设备为终端配置的SPS PDSCH传输的周期为1个时隙，配置的K值集合为{2，3，4}。
其中，网络侧设备下发给终端的用于激活时隙n中SPS PDSCH传输的DCI中指示的K值为2，则时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息可以在时隙n+2中反馈，由于时隙n+2为下行时隙，所以SPS PDSCH传输对应的PUCCH资源为无效的PUCCH资源。进而可以将时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至下一个K值指示的时隙进行反馈，即在时隙n+3中反馈时隙n中的SPS PDSCH传输对应的HARQ-ACK反馈信息。
进一步地，由于时隙n+1中的HARQ-ACK反馈信息也可以在n+3中反馈，则时隙n+3中的SPS PDSCH传输对应的PUCCH资源可以同时承载时隙n和时隙n+1中SPS PDSCH传输对应的HARQ-ACK反馈信息。当同一时隙中同时承载多个时隙中的SPS PDSCH传输对应的HARQ-ACK反馈信息时，该时隙承载的HARQ-ACK反馈信息的比特数会增多，进而该时隙对应的PUCCH资源也可能随着承载的比特数的变化而变化，从而可能存在以下三种的情况：
情况一，当时隙n+3同时承载的时隙n和时隙n+1中SPS PDSCH传输的HARQ-ACK反馈信息对应的PUCCH资源为有效PUCCH资源时，可以在时隙n+3中同时反馈时隙n和时隙n+1中SPS PDSCH传输的HARQ-ACK反馈信息，从而避免丢弃SPS PDSCH传输的HARQ-ACK反馈信息。也就是说， 根据n+3时隙同时承载的HARQ-ACK反馈信息的比特数，确定出的PUCCH资源为有效PUCCH资源。
情况二，请参考图5，时隙n+3中同时承载的时隙n和时隙n+1中SPS PDSCH的HARQ-ACK反馈信息所对应的PUCCH资源为无效PUCCH资源，且仅传输时隙n中SPS PDSCH传输对应的HARQ-ACK反馈信息对应的PUCCH资源为有效PUCCH资源或者仅传输时隙n+1中SPS PDSCH的HARQ-ACK反馈信息对应的PUCCH资源为有效PUCCH资源。即根据n+3时隙同时承载的HARQ-ACK反馈信息的比特数，确定出的PUCCH资源为无效PUCCH资源，但针对时隙n中SPS PDSCH传输对应的HARQ-ACK反馈信息对应的PUCCH资源为有效PUCCH资源，或者针对时隙n+1中SPS PDSCH的HARQ-ACK反馈信息对应的PUCCH资源为有效PUCCH资源，此种情况下有三种传输方式：
第一种，可以丢弃时隙n+1中SPS PDSCH传输对应的HARQ-ACK反馈信息，而在时隙n+3中仅传输时隙n中SPS PDSCH传输对应的HARQ-ACK反馈信息。
第二种，可以直接丢弃时隙n中SPS PDSCH传输对应的HARQ-ACK反馈信息，而在时隙n+3中仅传输时隙n+1中SPS PDSCH传输对应的HARQ-ACK反馈信息。
上述两种方式中，第二种方式和第一种方式相比，虽然都需要丢弃一个SPS PDSCH传输对应的HARQ-ACK反馈信息，但由于时隙n+1与时隙n+3之间的时隙差更小，因此还可以在一定程度上减小SPS PDSCH传输的HARQ-ACK反馈时延。
第三种，则可以继续将时隙n中SPS PDSCH对应的HARQ-ACK反馈信息进行延迟，也就是说，可以在将n中SPS PDSCH对应的HARQ-ACK反馈信息延迟至n+3后，在时隙n+3的基础上继续将n中SPS PDSCH对应的HARQ-ACK反馈信息向后延迟。例如，可以将n中SPS PDSCH对应的HARQ-ACK反馈信息延迟至时隙n+4中进行反馈。
进一步地，在将HARQ-ACK反馈信息延迟至时隙n+4中进行反馈后，若时隙n+4中仍没有有效的PUCCH资源，还可以按照配置的K值集合中从小到大K值的排序继续向后延迟，直至延迟到K值集合中的最后一个K值是指的时隙，若该时隙中仍为包括有效的PUCCH资源则可以将n中SPS PDSCH对应的HARQ-ACK反馈信息丢弃，因此可以使得SPS PDSCH传输对应的HARQ-ACK反馈信息更好的被上传到网络侧设备，减小SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃的可能性，从而减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题，提高传输性能。
情况三，时隙n+3同时承载的时隙n和时隙n+1中SPS PDSCH传输的HARQ-ACK反馈信息对应的PUCCH资源为无效PUCCH资源时，则可以将同时将时隙n和时隙n+1中SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至时隙n+4中进行反馈，即在时隙n+4中可以传输时隙n、时隙n+1以及时隙n+2中SPS PDSCH对应的HARQ-ACK反馈信息。因此，可以使得SPS PDSCH传输对应的HARQ-ACK反馈信息更好的被上传到网络侧设备，从而减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题，从而提升SPS PDSCH传输的传输性能。
进一步地，时隙n+4中具体是将时隙n、时隙n+1以及时隙n+2中SPS PDSCH对应的HARQ-ACK反馈信息反馈给网络侧设备还是丢弃，可以按照前述方式进行判断，在此不再赘述。
实施方式3
请参考图6，在本实施例中，假设网络侧设备为终端配置SPS PDSCH传输的周期为1个时隙，配置的K集合为{2，3}。
其中，若激活SPS PDSCH传输的DCI中指示的K值为3，则时隙n+2中的SPS PDSCH传输对应的HARQ-ACK反馈信息可以在时隙n+5进行反馈。然而，时隙n+5为下行时隙，所以该SPS PDSCH传输对应的PUCCH资源为 无效PUCCH资源，则可以将n+2中SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至下一个K值指示的时隙进行反馈。但是从配置的K值集合可知，3为该集合中的最后一个K值，不存在可以继续向后延迟的时序，因此，可以直接丢弃时隙n+2中SPS PDSCH对应的HARQ-ACK反馈信息。从而避免影响其他时隙中开始SPS PDSCH对应的HARQ-ACK反馈信息的反馈，节约延迟HARQ-ACK反馈信息所占用资源。
作为一种可选的实施方式，在本申请实施例中，当延迟后的时隙中还存在动态PDSCH传输对应的HARQ-ACK反馈信息时，即，延迟后的时隙中SPS PDSCH传输对应的PUCCH资源可以同时承载SPS PDSCH传输对应的HARQ-ACK反馈信息和动态PDSCH传输对应的HARQ-ACK反馈信息。
当确定出该PUCCH资源为有效PUCCH资源时，则可以通过该PUCCH资源同时上传SPS PDSCH传输对应的HARQ-ACK反馈信息和动态PDSCH传输对应的HARQ-ACK反馈信息。当确定出该PUCCH资源为无效PUCCH资源时，则可能将SPS PDSCH传输对应的HARQ-ACK反馈信息和动态PDSCH传输对应的HARQ-ACK反馈信息同时丢弃；或者可以仅丢弃其中的一个；或者还可以通过PUCCH资源上传动态PDSCH传输对应的HARQ-ACK反馈信息，而将SPS PDSCH传输对应的HARQ-ACK反馈信息继续向后延迟至其他时隙，具体延迟方式如前述实施方式1-3中所述的内容相同，此处不再赘述。
所以，通过上述方法，当该第一K值指示的时隙中与SPS PDSCH传输对应的PUCCH资源被确定为无效PUCCH资源时，可以将SPS PDSCH传输对应的HARQ-ACK反馈信息延迟至网络侧设备为终端配置的K值集合中的第二K值所指示的时隙进行反馈。因此可以使得SPS PDSCH传输对应的HARQ-ACK反馈信息更好的被上传到网络侧设备，从而减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题，从而提升SPS PDSCH传输的传输性能。
并且，通过上述方法，当延迟后的时隙中还存在动态PDSCH的 HARQ-ACK反馈信息时，可以在不改变反馈码本的基础上进行SPS PDSCH传输对应的HARQ-ACK反馈信息的反馈，因此可以进一步地减小或者避免因SPS PDSCH传输对应的HARQ-ACK反馈信息被丢弃，所导致的SPS PDSCH传输性能下降的问题。
