Description

重传响应反馈方法及装置、终端设备
本申请要求2021年4月6日提交中国专利局、申请号为202110369457.X、发明名称为“重传响应反馈方法及装置、终端设备”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
本申请涉及通信技术领域，具体涉及一种重传响应反馈方法及装置，还涉及一种终端设备。
背景技术
在5G NR(New Radio，新空口)中，下行数据调度时间指示如图1所示，其中，K0，K1单位都是时隙(slot)，K0表示PDSCH(Physical Downlink Shared Channel，物理下行共享信道)与PDCCH(Physical Downlink Control Channel，物理下行控制信道)的时间间隔，PDSCH用于传输下行数据，PDCCH用于传输DCI(Downlink Control Information，下行控制信息)；K1表示HARQ-ACK反馈与PDSCH的时间间隔。PDCCH的资源单元是CCE，一个PDCCH是n个连续的CCE。
动态调度PDSCH HARQ(Hybrid Automatic Repeat reQuest，混合式自动重传请求)-ACK反馈所用的PUCCH资源，gNB(generation NodeB，下一代基站)最多给UE(User Equipment，用户设备)配置4个HARQ-ACK比特范围，且配置每个范围内可用于反馈动态PDSCH HARQ-ACK的PUCCH资源集合(Resource Set)，即每个HARQ-ACK比特范围内均有唯一的PUCCH资源集合，每个PUCCH资源集合中可以包含多个PUCCH资源。动态调度DCI会指示一个PUCCH资源指示，UE根据此指示(及承载DCI的PDCCH起始CCE索引)确定PUCCH资源集合内用哪个PUCCH资源反馈动态调度PDSCH HARQ-ACK。
NR上下行均采用异步HARQ，HARQ-ACK信息既可以在PUCCH上承载，也可以在PDCCH上承载。NR R15仅支持UE在一个时隙仅有一个承载HARQ-ACK信息的PUCCH。如果UE检测到在时隙n接收PDSCH，或UE在时隙n检测到SPS(Semi-Persistent Scheduling，半持续调度)释放的DCI，UE在时隙(n+k)发送相应的HARQ-ACK信息。其中，k通过DCI中的PDSCH到HARQ的定时指示器来指示，如果DCI中没有该定时指示器，则通过高层参数DI-DataToUL-ACK来表示。
对于NR中的SPS，由于受到SPS周期的限制，会出现无法进行HARQ-ACK反馈的情况。比如图2所示，时隙n+2内SPS PDSCH的HARQ-ACK反馈在时隙n+5，但是由于时隙n+5全部为下行符号，无法进行HARQ-ACK反馈。

具体实施方式
为使本申请的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本申请的具体实施例做详细的说明。
HARQ是一种结合FEC(Forward Error Correction，前向纠错)与ARQ(Automatic Repeat reQuest，自动重传请求)方法的技术。FEC通过添加冗余信息，使得接收端能够纠正一部分错误，从而减少重传的次数。对于FEC无法纠正的错误，接收端会通过ARQ机制请求发送端重发数据。接收端使用检错码，通常为CRC(Cyclic Redundancy Check,循环冗余校验)校验，来检测接收到的数据包是否出错。如果无错，则接收端会发送一个肯定的确认(ACK)给发送端，发送端收到ACK后，会接着发送下一个数据包。如果出错，则接收端会丢弃该数据包，并发送一个否定的确认(NACK)给发送端，发送端收到NACK后，会重发相同的数据包。UE在一个HARQ反馈资源，即PUSCH或PDSCH上反馈的HARQ-ACK信息的整体称为HARQ-ACK码本。
NR中的SPS(Semi-Persistent Scheduling，半持续调度)是指半静态配置无线资源，并将该无线资源周期性地分配给某个特定UE。 使用SPS C-RNTI(Cell-Radio Network Temporary Identifier，小区无线网络临时标识)加扰的PDCCH指定UE所使用的无线资源(为了便于描述，后面将其称为SPS资源)，每过一个周期，UE就使用该SPS资源来收或发数据。gNB无需在该时隙重新下发PDCCH来指定分配的资源，降低了对应的PDCCH开销。
当只有SPS PDSCH HARQ-ACK反馈，没有调度PDCCH、或者SPS PDSCH激活PDCCH、或者SPS PDSCH去激活PDCCH的HARQ-ACK反馈时，采用SPS PDSCH HARQ-ACK码本，在配置了多个SPS PDSCH的情况下，HARQ-ACK比特顺序为：根据这个时隙或子时隙(slot/subslot)内PUCCH需要承载哪些时隙或子时隙内SPS PDSCH，确定所有的时隙或子时隙索引集合，遍历此集合内每个时隙或子时隙，按照每{SPS配置索引，服务小区索引}的下行时隙内HARQ-ACK升序排列，接着每个服务小区索引内按SPS配置索引内HARQ-ACK升序排列，最后按服务小区索引内HARQ-ACK的升序排列。
当有SPS PDSCH HARQ-ACK与动态调度PDSCH的HARQ-ACK一起进行反馈时，会按照高层信令的配置决定使用type 1 HARQ-ACK码本或type 2 HARQ-ACK码本。
type 1 HARQ-ACK码本为半静态码本，首先需要确定PDSCH可能位置的集合M，影响M的因素包括：K1的取值范围、时域资源分配配置、上下行的SCS(Sub-Carrier Space，子载波间隔)配置、半静态上下行帧结构配置。若采用DCI格式1_1调度PDSCH，K1的集合由高层信令配置；若采用DCI格式1_0调度PDSCH，K1的集合固定为{1,2,3,4,5,6,7,8}。K1为PUCCH的参数，其对应的SCS为PUCCH的SCS。type 1 HARQ-ACK码本中，需要根据上下行的SCS配置，确定下行对应的K1的集合K1DL；对于每一个K1DL集合对应的下行时隙，首先找出没有上下行帧结构冲突的PDSCH的可能的位置，然后找出没有重叠的PDSCH的可能的位置。NR R15的半静态码本 需要在这些可能的位置反馈HARQ-ACK。
type 2 HARQ-ACK码本为动态码本，码本的确定基于计数DAI(Downlink Assignment Index，下行链路分配索引)和总DAI。对于某一个PUCCH，总DAI为PDCCH监听时刻集合内从第一个DAI时刻至当前DAI时刻，在所有小区基站发送的DCI的总数量。计数DAI为PDCCH监听时刻集合内，基站在当前DAI时刻发送的从第一个小区至当前小区DCI次数的累加计数，与前一DAI时刻对应的总DAI之和。
本申请针对上面三种不同方式的码本，分别提出相应的解决方案，以保证SPS PDSCH HARQ-ACK的有效反馈。
本申请实施例的技术方案可以应用于各种移动通信系统，例如：GSM(GlobalSystem of Mobile Communication，全球移动通讯)系统、CDMA(Code Division MultipleAccess，码分多址)系统、WCDMA(Wideband Code Division Multiple Access，宽带码分多址)系统、GPRS(General Packet Radio Service，通用分组无线业务)、LTE(Long TermEvolution，长期演进)系统、LTE FDD(Frequency Division Duplex，频分双工)系统、LTE TDD(Time Division Duplex，时分双工)、UMTS(Universal MobileTelecommunication System，通用移动通信系统)、WiMAX(Worldwide Interoperabilityfor Microwave Access，全球互联微波接入)通信系统、5G(5th Generation)系统、NR(New Radio，新无线)等。

针对现有技术中SPS PDSCH HARQ-ACK反馈存在的问题，本申请实施例提供的一种重传响应反馈方法及装置，通过遍历各服务小区，确定上行信道资源需要反馈的每个服务小区内原始下行时隙及延后下行时隙的HARQ-ACK；分别获取所述原始下行时隙的HARQ-ACK信息及所述延后下行时隙的HARQ-ACK信息；根据所述原始下行时隙的HARQ-ACK信息及所述延后下行时隙的HARQ-ACK信息生成HARQ-ACK码本，使用上行信道发送所述HARQ-ACK码本。
如图4所示，是本申请实施例重传响应反馈方法的一种流程图，包括以下步骤：
步骤401，遍历各服务小区，确定上行信道资源需要反馈的每个服务小区内原始下行时隙及延后下行时隙的HARQ-ACK。
在该实施例中，各服务小区配置的PDSCH可以包括：SPS PDSCH和/或动态调度PDSCH。
如图5所示的服务小区上配置的PDSCH有：SPS PDSCH1和SPS PDSCH2，K1＝3。D表示下行信道资源，U表示上行信道资源。
带箭头的虚线指示编号为3的SPS PDSCH1(记为SPS1-3)的HARQ-ACK的反馈时隙Slot5，由于时隙Slot5对应的是下行信道资源，因此需要将该HARQ-ACK反馈延迟到后面PUCCH资源的时隙上，具体延迟到哪个时隙，本申请实施例不做限定，可以根据现有技术等来确定，比如延迟到下一个可用的PUCCH资源时隙Slot8上。
在本发明实施例中，所述原始下行时隙是指根据用于指示PDSCH到对应ACK/NACK反馈的时隙偏移值K1确定的ACK/NACK反馈对应的下行时隙；所述延后下行时隙是指需要延后发送根据所述K1确定的ACK/NACK反馈对应的下行时隙。
通过遍历各服务小区配置的PDSCH，可以确定上行信道资源需要反馈的每个服务小区内原始下行时隙的HARQ-ACK及延后下行时 隙的HARQ-ACK。比如图5示例中，上行信道资源Slot8内，需要反馈的原始下行时隙的HARQ-ACK有Slot5的SPS1 PDSCH1 HARQ-ACK，需要反馈的延后下行时隙有Slot3的SPS1 PDSCH1 HARQ-ACK。
步骤402，分别获取所述原始下行时隙的HARQ-ACK信息及所述延后下行时隙的HARQ-ACK信息。
步骤403，根据所述原始下行时隙的HARQ-ACK信息及所述延后下行时隙的HARQ-ACK信息生成HARQ-ACK码本。
由于针对不同码本，在各时隙内需要反馈的HARQ-ACK有不同的编码顺序。为此，在本申请实施例中，还提供了针对不同码本方式的HARQ-ACK码本生成方法，具体如下：
如果当前只有SPS PDSCH HARQ-ACK反馈，则将所述原始下行时隙对应的HARQ-ACK信息及所述延后下行时隙对应的HARQ-ACK信息按照SPS码本的比特顺序生成HARQ-ACK码本，即按照每{SPS配置索引，服务小区索引}的下行时隙内HARQ-ACK升序排列，接着每个服务小区索引内按SPS配置索引内HARQ-ACK升序排列，最后按服务小区索引内HARQ-ACK的升序排列，生成SPS PDSCH HARQ-ACK码本。
如果当前有动态调度PDSCH的HARQ-ACK反馈和/或PS PDSCH释放的PDCCH的HARQ-ACK反馈、并且有动态调度PDSCH的HARQ-ACK反馈和SPS PDSCH HARQ-ACK反馈，则根据高层配置信息确定需要使用的HARQ-ACK码本。相应地，需要采用不同的方式生成HARQ-ACK码本。
在生成半静态HARQ-ACK码本时，可以采用下面两种方式生成HARQ-ACK码本：
(1)将所述延后下行时隙的HARQ-ACK信息置于所述原始下行时隙的HARQ-ACK信息后面，生成半静态HARQ-ACK码本。
具体地，可以采用以下两种方式：
方式1是依次将每个服务小区的延后下行时隙的HARQ-ACK信息置于该服务小区的原始下行时隙的HARQ-ACK信息后面，生成半静态HARQ-ACK码本。
方式2是将所有服务小区的延后下行时隙的HARQ-ACK信息附在所有服务小区的原始下行时隙的HARQ-ACK信息后面，生成半静态HARQ-ACK码本。
参照图6所示服务小区配置的PDSCH进一步详细说明上述两种方式。
在该示例中有两个载波，分别为CC0，CC1，其中只有CC0发送PUCCH，SPS1和SPS2的HARQ-ACK反馈的偏置K1＝3。高层参数配置的K1时隙集合为{1,2,3}。
CC0服务小区上配置有1个SPS PDSCH，为SPS PDSCH1(为便于描述，后续将其称为SPS1)，其周期为1个时隙。SPS1配置为允许延后；
CC0服务小区上还配置有1个动态调度PDSCH，所在时隙为Slot6。
CC1服务小区上配置有1个SPS PDSCH，为SPS PDSCH2(为便于描述，后续将其称为SPS2)，其周期为3个时隙，SPS2配置为不允许延后。
假设各时隙内SPS PDSCH所对应的HARQ-ACK信息及SPS PDSCH发送情况如下表1所示，其中，ACK用1表示，NACK用0表示。
表1
Slot索引 Slot 0 1 2 3 4 5 6 7
CC0 1 1 1 NA NA 0 1 1
CC1 NA NA 1 NA NA 1 NA NA
在生成Slot8 PUCCH内HARQ-ACK信息时，判断CC0的延后时隙K1_def＝{6},CC1的延后时隙K1_def＝{6}。
首先，遍历各服务小区内K1时隙集合。然后再遍历延后HARQ-ACK反馈时隙，获取对应所述延后HARQ-ACK反馈时隙的SPS PDSCH HARQ-ACK信息。
对于Slot 5，Slot 6，Slot 7内PDSCH的HARQ-ACK对应时隙的确定，与现有技术相同，在此不再赘述。
CC0上，判断对于Slot8内PUCCH需要承载K1＝{1，2，3}PDSCH HARQ-ACK，确定所有的需要反馈PDSCH时隙索引集合为{slot5，slot6，slot 7}，遍历此集合内每个时隙，按照每下行时隙内PDSCH可能位置的HARQ-ACK升序排列为{0，1，0}。其中，slot 7上因为没有需要在此PUCCH上反馈的PDSCH，所以填充为NACK(0)。
CC1上，判断对于Slot8内PUCCH需要承载K1＝{1，2，3}PDSCH HARQ-ACK，确定所有的需要反馈PDSCH时隙索引集合为{slot5，slot6，slot 7}，遍历此集合内每个slot，按照每下行时隙内PDSCH可能位置的HARQ-ACK升序排列为{1，0，0}。其中，slot 6和slot7上因为没有需要在此PUCCH上反馈的PDSCH，所以填充为NACK(0)。
CC0上，时隙2内SPS PDSCH的HARQ-ACK，需要延后到Slot8上；同样，CC1上，时隙2内SPS PDSCH的HARQ-ACK，需要延后到Slot8上，由于SPS2配置为不允许延后，因此将CC1上时隙2内PDSCH的HARQ-ACK丢弃。
因此，根据上述方式1生成的码本为100/1/110/0，其中，前三位是CC0上按现有方式生成的比特信息，第四位是CC0上延后下行时 隙SPS PDSCH1的HARQ-ACK。第5-7位是CC1上按现有方式生成的比特信息，第8位是CC1上延后下行时隙SPS PDSCH2的HARQ-ACK。需要说明的是，码本中的斜线只是为了方便理解，实际码本中并不存在。
采用上述方式2时，HARQ-ACK码本的生成过程与方式1类似，区别在于，在方式2中需要最后再遍历延后HARQ-ACK反馈时隙并按小区索引排序，生成对应所有小区的SPS PDSCH HARQ-ACK信息。根据上述方式2生成的码本为100/110/10，其中，前三位是CC0上按现有方式生成的所有小区的原始下行时隙的HARQ-ACK信息，第4-6位是CC1上按现有方式生成的所有小区的原始下行时隙的HARQ-ACK信息，第7位是CC0上延后下行时隙的SPS PDSCH1的HARQ-ACK，第8位是CC1上延后下行时隙的SPS PDSCH2的HARQ-ACK。
(2)根据所述延后下行时隙扩展K1时隙集合，根据扩展后的K1时隙集合生成半静态HARQ-ACK码本。
具体地，根据所述延后下行时隙在所述K1时隙集合中添加延后时隙，得到扩展后的K1时隙集合。
下面参照图6所示服务小区配置的PDSCH对此方式进一步详细说明。
在生成Slot8 PUCCH内HARQ-ACK信息时，判断CC0的延后时隙K1_def＝{6},CC1的延后时隙K1_def＝{6}。所以根据延后下行时隙对K1时隙集合进行扩展，扩展后的K1时隙集合为K1＝{1,2,3,6}。
遍历上述K1时隙集合，对于时隙2内HARQ-ACK，CC0上，时隙2内SPS PDSCH的HARQ-ACK需要延后到Slot8上；同样，CC1上，时隙2内SPS PDSCH的HARQ-ACK需要延后到Slot8上，由于SPS2配置为不允许延后，因此将CC1上时隙2内PDSCH的HARQ-ACK丢弃。
CC0上，遍历此K1时隙集合内每个时隙，由于时隙2内只有一个SPS PDSCH，其对应的HARQ-ACK为1，因此，按照每下行时隙内SPS配置索引的HARQ-ACK升序排列为{1}；
CC1上，遍历此时隙集合K1内每个时隙，按照每下行时隙内SPS配置索引的HARQ-ACK升序排列为{1}；
对于Slot5，Slot6，Slot7内PDSCH的HARQ-ACK对应时隙的确定，与现有技术相同，在此不再赘述。
CC0上，判断对于Slot8内PUCCH需要承载K1＝{1，2，3}PDSCH HARQ-ACK，确定所有的需要反馈PDSCH时隙索引集合为{Slot5，Slot6，Slot7}，遍历此集合内每个时隙，按照每下行时隙内PDSCH可能位置的HARQ-ACK升序排列为{0，1，0}。其中，Slot 7上因为没有需要在此PUCCH上反馈的PDSCH，所以填充为NACK(0)。
CC1上，判断对于Slot8内PUCCH需要承载K1＝{1，2，3}PDSCH HARQ-ACK，确定所有的需要反馈PDSCH时隙索引集合为{slot5，Slot6，Slot7}，遍历此集合内每个时隙，按照每下行时隙内PDSCH可能位置的HARQ-ACK升序排列为{1，0，0}。其中，Slot6，Slot7上因为没有需要在此PUCCH上反馈的PDSCH，所以填充为NACK(0)。
基于上述过程，确定Slot8内的HARQ-ACK反馈信息为{11010100}。
在生成动态HARQ-ACK码本时，可以按照以下方式：
根据DCI内DAI指示生成第一码本，将所述延后下行时隙对应的HARQ-ACK信息生成第二码本，将所述第二码本置于所述第一码本后面，得到动态HARQ-ACK码本。
步骤404，使用上行信道发送所述HARQ-ACK码本。
本申请实施例提供的重传响应反馈方法，通过遍历各服务小区， 确定上行信道资源需要反馈的每个服务小区内原始下行时隙及延后下行时隙的HARQ-ACK；分别获取所述原始下行时隙的HARQ-ACK信息及所述延后下行时隙的HARQ-ACK信息；根据所述原始下行时隙的HARQ-ACK信息及所述延后下行时隙的HARQ-ACK信息生成HARQ-ACK码本，使用上行信道发送所述HARQ-ACK码本，从而可以保证SPS PDSCH HARQ-ACK的有效反馈，进而提高终端设备性能，提升通信质量。
前面提到，针对SPS PDSCH HARQ-ACK需要延后反馈时，具体可以延后到PUCCH资源的哪个时隙上，可以采用现有技术来确定。在图4所示本申请实施例中并不做限定。
进一步地，本申请还提供一种确定需要在上行信道资源内反馈SPS PDSCH HARQ-ACK的延后下行时隙的方法。遍历各服务小区，根据高层配置的第一配置参数确定上行信道资源内需要反馈SPS PDSCH HARQ-ACK的延后下行时隙。所述第一配置参数用于指示SPS PDSCH HARQ-ACK的最大允许的延后反馈时隙偏置，其单位为时隙或子时隙。
需要说明的是，所述第一配置参数可以同时指示所有SPS PDSCH配置都可以延后反馈HARQ-ACK；也可以指示一个或多个SPS PDSCH配置可以延后反馈，其它不可以延后反馈。另外，所有SPS PDSCH可以共享所述第一配置参数；或者每个SPS PDSCH对应各自的第一配置参数，对此本申请实施例不做限定。
进一步地，可以配置所有SPS PDSCH共享所述第一配置参数，也就是说，不同的SPS PDSCH具有同样的第一配置参数。或者，可以配置每个SPS PDSCH对应各自的第一配置参数，也就是说，对应不同的SPS PDSCH，其C对应的配置参数可以相同，也可以不同，对此本实施例不做限定。
比如，当SPS PDSCH不能延后反馈HARQ-ACK时，其对应的N＝0；当SPS PDSCH可以延后反馈HARQ-ACK时，其对应的N为 一个大于1的值，单位与此SPS PDSCH HARQ-ACK反馈的单位相同，可以为时隙或子时隙。
基于上述第一配置参数，确定上行信道资源需要反馈SPS PDSCH HARQ-ACK的延后下行时隙的一种实现方式如图7所示，包括以下步骤：
步骤701，统计上行信道资源对应的各时隙内需要反馈SPS PDSCH HARQ-ACK的原始下行时隙、以及可能需要在所述时隙内反馈SPS PDSCH HARQ-ACK的候选延后下行时隙。
具体地，需要遍历各服务小区、每个服务小区上配置的SPS PDSCH，根据各SPS PDSCH的配置参数，确定每个SPS PDSCH对应的HARQ-ACK的时隙。假设SPS PDSCH1所在的时隙记为时隙a1，其对应的HARQ-ACK所在的时隙记为时隙b1，SPS PDSCH1所在的时隙记为时隙a2，其对应的HARQ-ACK所在的时隙记为时隙b2。
遍历SPS PDSCH1，如果时隙b1内为上行链路UL符号，可以使用配置的SPS PDSCH HARQ-ACK PUCCH资源，则时隙b1内需要反馈SPS PDSCH HARQ-ACK的原始下行时隙包括时隙a1；
遍历SPS PDSCH2，如果时隙b2内为下行链路DL符号，无法使用配置的SPS PDSCH HARQ-A CK PUCCH资源，则可将时隙b2上对应SPS PDSCH2 HARQ-ACK的信息使用下一个可用的PUCCH资源比如时隙bn发送，则可能需要在时隙bn内反馈SPS PDSCH HARQ-ACK的原始下行时隙包括时隙a2。
步骤702，将统计得到的所述原始下行时隙和所述候选延后下行时隙取合集，得到各时隙对应的合集。
步骤703，依次将上行信道资源对应的各时隙作为当前时隙，将所述当前时隙对应的合集中的各候选延后下行时隙作为待检测时隙，检测所述待检测时隙对应的原始下行时隙与所述当前时隙的差值是否小于等于所述SPS PDSCH对应的第一配置参数。如果是，则执行 步骤704；否则，执行步骤705。
步骤704，确定所述候选延后下行时隙为在所述当前时隙内需要反馈SPS PDSCH HARQ-ACKR的延后下行时隙。
步骤705，确定所述候选延后下行时隙不是在所述当前时隙内需要反馈SPS PDSCH HARQ-ACKR的延后下行时隙。
下面结合图8举例说明利用图7所示实施例实现SPS PDSCH HARQ-ACK的过程。
如图8所示，有两个载波，分别为CC0，CC1，其中只有CC0发送PUCCH，SPS1和SPS2的HARQ-ACK反馈的偏置K1＝3。
CC0服务小区上配置的SPS PDSCH个数为1，为SPS PDSCH1(为便于描述，后续将其称为SPS1)，其周期为1个时隙。SPS1配置为允许延后，且其对应的第一配置参数N 1＝3；
CC1服务小区上配置的SPS PDSCH个数为1，为SPS PDSCH2(为便于描述，后续将其称为SPS2)，其周期为3个时隙，SPS2配置为不允许延后，即其对应的第一配置参数N 2＝0。
SPS1所在的时隙为Slot0、Slot1、Slot2、Slot5、Slot6、Slot7，对应Slot0、Slot1、Slot2、Slot5的HARQ-ACK信息所在时隙应为：Slot3、Slot4、Slot5、Slot8，在Slot5内由于是下行链路DL符号，无法使用配置的SPS PDSCH HARQ-ACK PUCCH资源。一种方式是将Slot5上对应SPS1的HARQ-ACK信息使用下一个可用的PUCCH资源即Slot8发送。
SPS2所在的时隙为Slot2、Slot5，对应Slot2、Slot5的HARQ-ACK信息所在时隙应为Slot5、Slot8。同样，在Slot5内由于是下行链路DL符号，无法使用配置的SPS PDSCH HARQ-ACK PUCCH资源。一种方式是将Slot5上对应SPS2的HARQ-ACK信息使用下一个可用的PUCCH资源即Slot8发送。
因此，根据上述步骤401，统计上行信道资源PUCCH对应的各时隙内需要反馈SPS PDSCH HARQ-ACK的原始下行时隙，分别为：
Slot3：SPS1-Slot0；
Slot4：SPS1-Slot1；
Slot8：SPS1-Slot5、SPS2-Slot5；
统计上行信道资源PUCCH对应的各时隙内可能需要在所述时隙内反馈SPS PDSCH HARQ-ACK的延后下行时隙，分别为：
Slot8：SPS1-Slot2、SPS2-Slot2；
根据上述步骤702，将统计得到的所述原始下行时隙和所述延后下行时隙取合集，得到各时隙对应的合集，对应Slot8的合集为{原始下行时隙：SPS1-Slot5、SPS2-Slot5；延后下行时隙：SPS1-Slot5、SPS2-Slot5}。
根据上述步骤703及步骤704，依次将上行信道资源对应的各时隙Slot3、Slot4、Slot8作为当前时隙，将所述当前时隙对应的合集中的各延后下行时隙作为待检测时隙，检测所述待检测时隙对应的原始下行时隙与所述当前时隙的差值是否小于等于所述SPS PDSCH对应的第一配置参数。
对于Slot8内的延后下行时隙SPS1-Slot2，其对应的SPS PDSCH HARQ-ACK的原始下行时隙为Slot5，与Slot8的差值为3。SPS1配置为允许延后，且N 1＝3；所述差值＝3，等于SPS1对应的延后阈值3。因此，确定在Slot8反馈延后下行时隙Slot2-SPS1对应的SPS PDSCH HARQ-ACK。
对于Slot8内的延后下行时隙Slot2-SPS2，其对应的SPS PDSCH HARQ-ACK的原始下行时隙为Slot5，与Slot8的差值为3。因为SPS2配置为不允许延后，其对应的第一配置参数N 2＝0，所述差值＝3，大于SPS2对应的延后阈值0，因此不能在Slot8反馈延后下行时隙 Slot5-SPS2对应的SPS PDSCH HARQ-ACK。
假设各时隙内SPS PDSCH所对应的HARQ-ACK信息及SPS PDSCH发送情况如下表2所示，其中，ACK用1表示，NACK用0表示。
表2
Slot索引 Slot 0 1 2 3 4 5 6 7
CC0 1 1 1 NA NA 0 1 1
CC1 NA NA 1 NA NA 1 NA NA
根据上述分析，最终的Slot8上的HARQ-ACK反馈信息为{101}。
所述第三参数g用于指示在所述反馈对应SPS PDSCH的HARQ-ACK的时隙没有可用的PUCCH资源情况下，可延后反馈对应SPS PDSCH的HARQ-ACK的时隙，g∈{1…N}，N表示可延后反馈对应SPS PDSCH的HARQ-ACK的时隙的最大值，即前面所述的延后阈值。
相应地，基于上述第一配置信息，确定需要在上行信道资源各时隙内反馈SPS PDSCH HARQ-ACK的延后下行时隙的一种实现流程如图9所示，包括以下步骤：
步骤901，遍历各服务小区，确定需要反馈SPS PDSCH HARQ-ACK的候选时隙。
步骤902，检查所述候选时隙是否有可用的PUCCH资源；如果有，则执行步骤903；否则，步骤904。
步骤903，确定所述候选时隙为反馈所述SPS PDSCH HARQ-ACK的原始下行时隙。
步骤904，根据所述第一配置参数确定反馈所述SPS PDSCH HARQ-ACK的延后下行时隙。
步骤905，统计上行信道资源每个时隙内需要反馈SPS PDSCH HARQ-ACK的延后下行时隙。
仍以图8所示为例，CC0服务小区上配置的SPS PDSCH个数为1，其周期为1个时隙。SPS1配置为允许延后，且其对应的第一配置参数N 1＝3；CC1服务小区上配置的上SPS PDSCH个数为1，其周期为3个时隙，SPS2配置为不允许延后，即其对应的第一配置参数N 2＝0。
利用图9所示的方法，遍历各服务小区上配置的SPS PDSCH，可以确定Slot8内需要反馈的下行时隙包括：CC0上Slot5的SPS PDSCH HARQ-ACK和Slot2的SPS PDSCH HARQ-ACK、CC1上Slot5的SPS PDSCH HARQ-ACK。根据表1中的HARQ-ACK信息，可以确定Slot8上的HARQ-ACK反馈信息为{101}。
利用上述图7或图9所示实施例的方法，可以更方便、准确地确定上行信道资源需要反馈SPS PDSCH HARQ-ACK的延后下行时隙。
相应地，本申请实施例还提供一种重传响应反馈装置，如图10所示，在该装置的一种实施例中，所述装置包括以下各模块：

如图11所示，所述半静态码本生成模块142包括：第一半静态码本生成单元1421、或者第二半静态码本生成单元1422。
所述第一半静态码本生成单元1421，用于将所述延后下行时隙的HARQ-ACK信息置于所述原始下行时隙的HARQ-ACK信息后面，生成半静态HARQ-ACK码本；
所述第二半静态码本生成单元1422，用于根据所述延后下行时隙扩展K1时隙集合，根据扩展后的K1时隙集合生成半静态HARQ-ACK码本。
在实际应用中，所述第一半静态码本生成单元1421具体可以依次将每个服务小区的延后下行时隙的HARQ-ACK信息置于该服务小区的原始下行时隙的HARQ-ACK信息后面，生成半静态HARQ-ACK码本；或者将所有服务小区的延后下行时隙的HARQ-ACK信息置于所有服务小区的原始下行时隙的HARQ-ACK信息后面、并按小区索引排序，生成半静态HARQ-ACK码本。
其中，所述第二半静态码本生成单元1422具体可以根据所述延后下行时隙在所述K1时隙集合中添加延后时隙，得到扩展后的K1时隙集合，根据扩展后的K1时隙集合生成半静态HARQ-ACK码本。

在本申请实施例中，针对SPS PDSCH HARQ-ACK需要延后反馈时，具体可以延后到PUCCH资源的哪个时隙上，可以采用现有技术来确定，对此本申请实施例中并不做限定。
进一步地，在本申请重传响应反馈装置另一实施例中，还可以利 用高层配置的第一配置参数确定上行信道资源内需要反馈SPS PDSCH HARQ-ACK的延后下行时隙。所述第一配置参数用于指示SPS PDSCH HARQ-ACK的最大允许的延后反馈时隙偏置，其单位为时隙或子时隙。
需要说明的是，所述第一配置参数可以同时指示所有SPS PDSCH配置都可以延后反馈HARQ-ACK；也可以指示一个或多个SPS PDSCH配置可以延后反馈，其它不可以延后反馈。另外，所有SPS PDSCH可以共享所述第一配置参数；或者每个SPS PDSCH对应各自的第一配置参数，对此本申请实施例不做限定。

相应地，在该实施例中，所述延后下行时隙确定模块12可以通过遍历各服务小区配置的SPS PDSCH，根据所述第一配置参数确定上行信道资源每个时隙内需要反馈SPS PDSCH HARQ-ACK的延后下行时隙。
