值的注意的是,如果所述物理下行信道是PDCCH,那么,终端只需反馈 指定PDCCH对应的HARQ-ACK,其中,所述指定的PDCCH可以是指示SPS PDSCH释放的PDCCH、指示辅小区休眠(Scell dormancy)且没有调度PDSCH的PDCCH、指示传输配置指示(Transmission Configuration Indicator,TCI)状态(State)更新的PDCCH等。
本实施例中,终端通过根据物理下行信道对应的HARQ-ACK码本类型和/或场景类型,确定目标HARQ-ACK码本,由此,能够提供一种有效的多播HARQ-ACK和/或单播HARQ-ACK的HARQ-ACK码本确定方案,实现HARQ-ACK信息的上报,确保了通信系统的性能。
如图3所示,为本申请一示例性实施例提供的HARQ-ACK码本的确定方法300的流程示意图,该方法300可以但不限于由终端执行,具体可由安装于终端中的硬件和/或软件执行。本实施例中,所述方法300至少可以包括如下步骤。
S310,终端根据物理下行信道对应的HARQ-ACK码本类型和/或场景类型,确定目标HARQ-ACK码本。
其中,所述物理下行信道对应的HARQ-ACK码本类型包括类型type 1 HARQ-ACK码本和type 2 HARQ-ACK码本;所述物理下行信道对应的场景类型包括第一场景和第二场景,所述第一场景为所述终端在一个PUCCH上上报候选PDSCH接收时机中接收到的指定物理下行信道对应的HARQ-ACK,所述第二场景为除所述第一场景之外的场景。
可以理解,S310的实现过程除了可参照方法实施例200中的相关描述,在一种可能的实现方式中,所述指定物理下行信道可以包括以下(11)-(13)中的任一项。
(11)特定PDCCH,所述特定PDCCH承载第一格式的下行控制信息(Downlink Control Information,DCI)、且所述第一格式的DCI指示释放SPS PDSCH,其中,所述第一格式的DCI对应的下行分配索引(Downlink assignment index,DAI)=1。
可选的,在所述特定PDCCH为单播物理下行信道(如配置调度的无线网络临时标识(Configured Scheduling Radio Network Temporary Identifier,CS-RNTI)加扰的PDCCH)的情况下,所述第一格式为DCI 1_0;或者,在所述特定PDCCH为多播物理下行信道(如组配置调度的RNTI(Group-Configured Scheduling-RNTI,G-CS-RNTI)加扰的情况下,所述第二格式的DCI为DCI 4_1。
(12)特定PDSCH,所述特定PDSCH由第二格式的DCI进行调度,且所述第二格式的DCI对应的DAI=1。
可选的,在所述特定PDSCH为单播物理下行信道(如小区RNTI(Cell RNTI,C-RNTI)、小区无线网络临时标识(Cell-Radio Network Temporary Identifier,C-RNTI)加扰)的情况下,所述第二格式的DCI为DCI 1_0;或者,在所述特定PDSCH为多播物理下行信道(如group RNTI,G-RNTI加扰)的情况下,所述第二格式的DCI为DCI 4_1。所述DAI为计数器器型DAI(Counter DAI,C-DAI)
此外,在一种实现方式中,所述特定PDSCH可以位于主小区(Primary cell,PCell),例如,在所述特定PDSCH为单播PDSCH的情况下,所述单播PDSCH位于PCell。相应的,在所述特定PDSCH为多播PDSCH的情况下,所述多播PDSCH可以位于PCell,也可以位于除PCell之外的其他小区,如配置了多播接收的小区。
(13)至少一个SPS PDSCH。
当然,在另一种实现方式中,所述终端根据物理下行信道对应的HARQ-ACK码本类型和/或场景类型确定目标HARQ-ACK码本的过程有多种,下面结合两种不同的实现方式进行说明,内容如下。
实现方式1
在第一物理下行信道对应的HARQ-ACK码本类型为所述type 1 HARQ-ACK码本(也可以称作type 1类型,或者半静态码本类型)、第二物理下行信道对应的HARQ-ACK码本类型为所述type 2 HARQ-ACK码本(也可以称作type 2类型,或者动态码本类型)的情况下,所述终端生成如下HARQ-ACK子码本中的至少两项:第一HARQ-ACK子码本、第二HARQ-ACK子码本和第三HARQ-ACK子码本,以及将生成的HARQ-ACK子码本级联得到所述目标HARQ-ACK码本。
其中,所述第一HARQ-ACK子码本与所述第一物理下行信道对应。作为一种可能的实现方式,当所述第一物理下行信道对应的场景类型不同的情况下,所述终端生成第一HARQ-ACK子码本的方式也可以不同,例如,在所述第一物理下行信道对应的场景类型为所述第一场景的情况下,所述终端根据接收到的所述第一物理下行信道对应的HARQ-ACK生成所述第一HARQ-ACK子码本。
又例如,在所述第一物理下行信道对应的场景类型为所述第二场景的情 况下,所述终端根据第一物理下行信道对应的时域资源分配表(Time domain resource assignment,TDRA)确定候选PDSCH接收时机(candidate PDSCH reception occasion),以及根据所述候选PDSCH接收时机生成所述第一HARQ-ACK子码本。可以理解,所述终端在根据TDRA确定所述候选PDSCH接收时机时,还可以结合PDSCH到HARQ-ACK反馈的定时K1、半静态上下行配置等实现候选PDSCH接收时机的确定。其中,所述K1表示终端从PDSCH接收位置所在时间单元到HARQ反馈的时间单元数,即当终端在时间单元n接收到PDSCH,则在时间单元n+K1反馈其对应的HARQ信息。
另外,所述第一HARQ-ACK子码本中可以包括第一物理下行信道中的DG PDSCH对应的HARQ-ACK子码本和/或SPS PDSCH对应的HARQ-ACK子码本,即对于type 1 HARQ-ACK码本,DG PDSCH以及SPS PDSCH的HARQ-ACK均可以根据候选PDSCH接收时机确定。
所述第二HARQ-ACK子码本与所述第二物理下行信道中的DG PDSCH对应。一种实现方式中,所述终端可以根据type 2码本生成方法(如根据DAI)生成所述第二HARQ-ACK子码本。
所述第三HARQ-ACK子码本与所述第二物理下行信道中的SPS PDSCH对应。一种实现方式中,所述终端可以根据SPS PDSCH HARQ-ACK码本生成方法生成所述第三HARQ-ACK子码本。例如,所述终端可以根据服务小区索引、SPS PDSCH配置索引、SPS PDSCH所在时隙等生成所述第三HARQ-ACK子码本。值得注意的是,所述第三HARQ-ACK子码本只包含所述第二物理下行信道中的SPS PDSCH对应的HARQ-ACK。
当然,对于实现方式1中提及的所述第一物理下行信道为单播物理下行信道(如单播PDSCH、单播PDCCH),所述第二物理下行信道为多播物理下行信道(如多播PDSCH、多播PDCCH),或者,所述第一物理下行信道为多播物理下行信道,所述第二物理下行信道为单播物理下行信道。
此外,在一种实现方式中,所述终端在对生成的HARQ-ACK子码本进行级联时,各HARQ-ACK子码本之间的级联顺序可以由协议约定、高层配置、或终端自主确定实现,以确保终端和网络侧设备对各HARQ-ACK子码本的顺序理解一致,进而使得网络侧设备在接收到终端发送的目标HARQ-ACK码本时,清楚如SPS PDSCH对应的HARQ-ACK在目标HARQ-ACK码本中的位置,以实现确定的资源调度。
需要注意的是,如果所述各HARQ-ACK子码本之间的级联顺序由终端 自主确定,那么,所述终端可以上报级联顺序给网络侧设备。
基于前述实现方式1的描述,假设单播HARQ-ACK码本被配置type 1类型,即pdsch-HARQ-ACK-Codebook=semi-static,多播HARQ-ACK码本被配置为type 2类型,即pdsch-HARQ-ACK-Codebook-Multicast=dynamic,且终端被激活了单播SPS PDSCH和多播SPS PDSCH,那么,所述终端可以按照如下示例1或示例2生成目标HARQ-ACK码本,内容如下。
示例1
如果在某个上行时间单元(如时隙或子时隙)上,终端被调度反馈单播DG PDSCH对应的HARQ-ACK、单播SPS PDSCH对应的HARQ-ACK、多播DG PDSCH对应的HARQ-ACK、多播SPS PDSCH的HARQ-ACK,那么,所述终端可以按照如下方式确定HARQ-ACK码本。
(a)由于单播PDSCH(即第一物理下行信道)对应的场景类型为第二场景,那么,终端可以根据单播PDSCH对应TDRA表格(也可以称为单播DCI对应的TDRA表格)、K1(也可以称为单播DCI对应的K1)以及上下行配置确定单播对应的候选PDSCH接收时机,再根据候选PDSCH接收时机生成单播PDSCH对应的第一HARQ-ACK子码本,该第一HARQ-ACK子码本中包括单播DG PDSCH以及单播SPS PDSCH对应的HARQ-ACK。
(b)终端可以根据DAI,生成多播DG PDSCH对应的第二HARQ-ACK子码本。
(c)终端可以根据SPS PDSCH配置索引、SPS PDSCH所在时隙等生成多播SPS PDSCH对应的第三HARQ-ACK子码本。
(d)终端按照第一顺序将第一HARQ-ACK子码本、第二HARQ-ACK子码本、第三HARQ-ACK子码本进行级联,得到目标HARQ-ACK码本。其中,所述第一顺序可以为(第一HARQ-ACK子码本、第二HARQ-ACK子码本、第三HARQ-ACK子码本)、(第一HARQ-ACK子码本、第三HARQ-ACK子码本、第二HARQ-ACK子码本)、(第三HARQ-ACK子码本、第二HARQ-ACK子码本、第一HARQ-ACK子码本)等,在此不做限制。
值的注意的是,在示例1中,单播DG PDSCH以及单播SPS PDSCH属于前述的第一物理下行信道;多播SPS PDSCH以及多播DG PDSCH属于前述的第二物理下行信道。
示例2
如果在某个上行时间单元(如时隙或子时隙),终端被调度反馈单播DG  PDSCH(或单播DG PDCCH)的HARQ-ACK、多播DG PDSCH对应的HARQ-ACK以及多播SPS PDSCH对应的HARQ-ACK。其中,单播DG PDSCH为Pcell上由DCI 1_0调度的PDSCH,且DCI 1_0对应DAI=1(或者是指示SPS PDSCH释放的单播DCI或者指示Scell dormancy的单播DCI),即所述单播DG PDSCH(或单播PDCCH)对应的场景类型为第一场景。那么,所述终端可以按照如下方式确定目标HARQ-ACK码本。
(a)所述终端生成单播DG PDSCH(或单播DG PDCCH)对应的第一HARQ-ACK子码本。
(b)所述终端可根据DAI生成多播DG PDSCH对应的第二HARQ-ACK子码本。
(c)所述终端可根据SPS PDSCH配置索引、SPS PDSCH所在时隙等生成多播SPS PDSCH对应的第三HARQ-ACK子码本。
(d)终端按照第二顺序将第一HARQ-ACK子码本、第二HARQ-ACK子码本、第三HARQ-ACK子码本进行级联,得到目标HARQ-ACK码本。
其中,所述第二顺序可以为(第一HARQ-ACK子码本、第二HARQ-ACK子码本、第三HARQ-ACK子码本)、(第一HARQ-ACK子码本、第三HARQ-ACK子码本、第二HARQ-ACK子码本)、(第三HARQ-ACK子码本、第二HARQ-ACK子码本、第一HARQ-ACK子码本)等,在此不做限制。
此外,如果单播HARQ-ACK码本被配置type 2类型,即pdsch-HARQ-ACK-Codebook-Multicast=dynamic,多播HARQ-ACK码本被配置为type 1类型,即pdsch-HARQ-ACK-Codebook=semi-static,且终端被激活了单播SPS PDSCH和多播SPS PDSCH,那么,所述终端确定所述目标HARQ-ACK码本的方式与前述示例1和示例2类似,为避免重复,在此不再赘述。
实现方式2
在第一物理下行信道对应的HARQ-ACK码本类型为所述type 1 HARQ-ACK码本、第二物理下行信道对应的HARQ-ACK码本类型为所述type 2 HARQ-ACK码本的情况下,所述终端执行以下(21)或(22)。
(21)在所述第一物理下行信道对应场景类型为所述第二场景的情况下,生成如下HARQ-ACK子码本中的至少两项:第一HARQ-ACK子码本、第二HARQ-ACK子码本和第三HARQ-ACK子码本,以及将生成的HARQ-ACK子码本级联得到所述目标HARQ-ACK码本,其中,所述第一HARQ-ACK子 码本与所述第一物理下行信道对应,所述第二HARQ-ACK子码本与所述第二物理下行信道中的DG PDSCH对应,所述第三HARQ-ACK子码本与所述第二物理下行信道中的SPS PDSCH对应。其中,所述第一物理下行信道为单播物理下行信道,所述第二物理下行信道为多播物理下行信道,或者,所述第一物理下行信道为多播物理下行信道,所述第二物理下行信道为单播物理下行信道。
可以理解,(21)中所提及的实现方式具有与前述实现方式1相同或相应的技术特征,因此,关于(21)的实现过程可参照方法实现方式1中的相关描述,为避免重复,在此不再赘述。
(22)在所述第一物理下行信道对应场景类型为所述第一场景的情况下,或者,在需要反馈的目标HARQ-ACK中仅包括第一物理下行信道中SPS PDSCH对应的HARQ-ACK的情况下,生成第四HARQ-ACK子码本和/或第五HARQ-ACK子码本,以及将所述第四HARQ-ACK子码本和所述第五HARQ-ACK子码本级联,得到所述HARQ-ACK码本。
其中,所述第四HARQ-ACK子码本与所述第二物理下行信道中的DG PDSCH对应。一种实现方式中,所述终端可以根据type 2码本生成方法(如根据DAI)生成所述第四HARQ-ACK子码本。
所述第五HARQ-ACK子码本与第一物理下行信道中的SPS PDSCH、第二物理下行信道中的SPS PDSCH、所述第一物理下行信道中的所述指定物理下行信道中的至少一项对应。一种实现方式中,所述终端可以根据SPS PDSCH HARQ-ACK码本生成方法生成所述第五HARQ-ACK子码本。例如,所述终端可以根据服务小区索引、SPS PDSCH配置索引、SPS PDSCH所在时隙等生成所述第五HARQ-ACK子码本。
当然,对于实现方式2中提及的所述第一物理下行信道为单播物理下行信道,所述第二物理下行信道为多播物理下行信道,或者,所述第一物理下行信道为多播物理下行信道,所述第二物理下行信道为单播物理下行信道。
可选的,所述终端在对生成的第四HARQ-ACK子码本和第五HARQ-ACK子码本进行级联时,所涉及的级联顺序可以由协议约定、高层配置、网络侧配置或终端自主确定实现,以确保终端和网络侧设备对第四HARQ-ACK子码本和第五HARQ-ACK子码本的顺序的理解一致,进而使得网络侧设备在接收到终端发送的目标HARQ-ACK码本时,清楚如SPS PDSCH对应的HARQ-ACK在目标HARQ-ACK码本中的位置。
需要注意的是,如果所述第四HARQ-ACK子码本和第五HARQ-ACK子码本之间的级联顺序由终端自主确定,那么,所述终端可以上报级联顺序给网络侧设备。
基于前述实现方式2的描述,假设单播HARQ-ACK码本被配置type 1类型,即pdsch-HARQ-ACK-Codebook=semi-static,多播HARQ-ACK码本被配置为type 2类型,即pdsch-HARQ-ACK-Codebook-Multicast=dynamic,且所述终端被激活了单播SPS PDSCH和多播SPS PDSCH,那么,所述终端可以按照如下示例3或示例4生成目标HARQ-ACK码本,内容如下。
示例3
在某个上行时间单元(如时隙或子时隙)上,终端被调度反馈单播SPS PDSCH对应的HARQ-ACK、多播DG PDSCH对应的HARQ-ACK以及多播SPS PDSCH对应的HARQ-ACK,那么,所述终端可以按照如下方式确定目标HARQ-ACK码本。

此外,相对于相关技术中HARQ-ACK反馈,本申请仅进行一次SPS PDSCH的HARQ-ACK码本生成、反馈,从而能够有效避免相关技术中存在的SPS PDSCH的HARQ-ACK重复生成问题,减少码本大小,提高通信系统的有效性。
