S210,接收反馈指示信息。
其中,所述反馈指示信息用于指示所述终端是否传输目标反馈信息。
一种可能的实现方式中,所述反馈指示信息可以由网络设备下发,并通过目标下行控制信息(Downlink Control Information,DCI)传输给所述终端,以指示所述终端是否传输目标反馈信息。在此情况下,所述目标DCI可以是调度数据的DCI,也可以是非调度数据的DCI。例如,所述调度数据的DCI可以包括调度上/下行数据的DCI、激活配置授权(Configured Grant,CG)PUSCH的DCI、激活SPS PDSCH的DCI中的至少一个。所述非调度数据的DCI可以包括组公共(group common,GC)DCI、触发非周期性-信道状态信息(Aperiodic-Channel State Information,A-CSI)的DCI、激活半持续 (Semi-Persistent,SP)-CSI的DCI、触发探测参考信号(Sounding Reference Signal,SRS)的DCI等中的至少一个。
另一种可能的实现方式中,在SPS PDSCH场景下,所述反馈指示信息还可通过高层信令配置和/或激活SPS PDSCH的DCI指示等,其中,所述高层信令可以包括如无线资源控制(Radio Resource Control,RRC)信令等,一种实现方式中,可通过RRC信令等高层信令为每个SPS PDSCH配置相应的反馈指示信息。
所述目标反馈信息可以是由于信道条件差、时域资源冲突等原因导致的网络设备并未接收到的反馈信息。例如,在本实施例中,所述目标反馈信息可以是所述终端在目标时间窗内反馈的反馈信息,如配置或调度在所述目标时间窗内反馈的HARQ-ACK(包括由于某种原因终端最终没有传输的HARQ-ACK);又例如,所述目标反馈信息还可以是所述终端在目标时间窗内接收到的第一下行传输对应的反馈信息,如配置或调度在所述目标时间窗中传输的下行传输对应的反馈信息等。
一种实现方式中,前述的目标时间窗可以为上行时间窗或下行时间窗,在所述目标时间窗为上行时间窗的情况下,所述目标反馈信息可以为所述终端在目标时间窗内反馈的反馈信息;在所述目标时间窗为下行时间窗的情况下,所述目标反馈信息可以为所述终端在目标时间窗内接收到的目标下行传输对应的反馈信息,对此,本实施例不做限制。
S220,在所述反馈指示信息指示所述终端传输所述目标反馈信息的情况下,传输所述目标反馈信息。
其中,所述终端传输所述目标反馈信息的时间可以由预定义方式确定,也可以由网络设备配置或指示(如通过RRC、DCI指示)等,本实施例对此不做限制。
此外,一种实现方式中,在所述反馈指示信息指示所述终端不传输所述目标反馈信息的情况下,所述终端不传输目标反馈信息等。
本实施例给出的反馈信息传输方法200中,终端通过接收反馈指示信息,并在所述反馈指示信息指示所述终端传输所述目标反馈信息的情况下,传输所述目标反馈信息。由此,一方面,本实施例能够通过反馈指示信息触发终端传输目标反馈信息,从而有效提高终端反馈目标反馈信息的反馈机会,确保目标反馈信息的有效反馈;另一方面,本实施例还有效解决了由于反馈信息与DL符号冲突而被丢弃,或者与高优先级的信道/信号冲突而被取消传输,导致的反馈信息无法传输至网络设备的问题,确保通信性能。
如图3所示,为本申请一示例性实施例提供的反馈信息传输方法300的流程示意图,该方法300可应用但不限于终端,具体可由安装于所述终端中的软件和/或硬件执行,所述方法300至少可以包括如下步骤。
S310,接收反馈指示信息。
所述反馈指示信息用于指示所述终端是否传输目标反馈信息,所述目标反馈信息是所述终端在目标时间窗内反馈的反馈信息,或者,所述目标反馈信息是所述终端在目标时间窗内接收到的第一下行传输对应的反馈信息。
其中,S310的具体实现方式除可参照前述S210的详细描述之外,在本实施例中,所述第一下行传输可以包括以下(1)-(4)中至少一项。
(1)调度在所述目标时间窗内传输的PDSCH或PDCCH,其中,所述PDSCH的调度可通过DCI实现。
(2)在目标时间窗内传输的PDCCH。
(3)预配置在所述目标时间窗内传输的PDSCH。
其中,可由网络设备或高层信令进行PDSCH传输的预配置,例如通过高层信令配置并通过DCI激活的SPS PDSCH,也可以由所述终端实现PDSCH传输的预配置,并将配置结果同步至所述网络设备,本实施例在此不做限制。
(4)所述目标时间窗内的候选PDSCH接收机会对应的PDSCH。
其中,对于候选PDSCH接收机会,即潜在PDSCH接收机会,所述终端可以根据PDCCH检测机会、PDSCH的时域资源分配(Time Domain Resource  Allocation,TDRA)信息、K1(即PDSCH到HARQ-ACK反馈定时)集合、半静态上行配置、动态时隙格式指示(Slot Format Indication,SFI)中的至少一项确定。
对于前述的K1集合,可以理解的是,可以通过RRC配置为每个终端配置或定义HARQ-ACK反馈定时集合,该集合中包含一个或多个HARQ-ACK定时的值,称为K1值,该K1可以是以时隙为单位的,也可以是以子时隙为单位的。由此,基站在动态调度下行传输时,会在DCI中以索引的方式指示一个K1值,该K1是从HARQ-ACK反馈定时集合中选择的一个值,用于通知终端反馈HARQ-ACK的时刻。
所述目标时间窗可以通过以下方式(1)-(4)中的至少一项确定。
(1)高层配置。如RRC指示等,一种实现方式中,可通过RRC指示所述目标时间窗的绝对时间长度,或者所述目标时间窗包含的时间单元的数量、索引、起始时间、结束时间等。

(3)隐式获取。一种实现方式中,所述目标时间窗可以与业务相关联,例如,目标时间窗的长度与关联业务的时延要求等相关。
(4)目标DCI指示。其中,所述目标DCI指示与前述RRC指示类似,可以通过目标DCI指示所述目标时间窗的绝对时间长度,或者所述目标时间窗包含的时间单元的数量、索引、起始时间、结束时间等。
可以理解的是,在前述几种实现方式中,可以仅根据(1)-(4)中的任一个确定所述目标时间窗,也可以根据(1)-(4)中的两个或多个共同确定所述目标时间窗,例如可通过高层信令配置一个或多个目标时间窗,并通过DCI指示其中的一个为目标时间窗。本实施例对此不再赘述。
在前述情况下,所述目标时间窗可以为绝对时间(如4ms、10ms等),也可以包括至少一个时间单元。其中,所述时间单元可以是为时隙(slot)、子时隙、符号(symbol,如OFDM)集或符号等。
本实施例中,所述时间单元可以为上行时间单元或下行时间单元。可选地,在所述目标时间窗包括至少一个上行时间单元时,所述上行时间单元可以为以下(1)-(4)中的至少一项。
(1)通过高层信令配置为上行时间单元的时间单元。
其中,基站可以通过高层参数tdd-UL-DL-ConfigurationCommon和/或tdd-UL-DL-Configuration Dedicated半静态地配置slot格式。
(2)通过动态(dynamic)信令SFI指示为上行时间单元的时间单元。
其中,SFI可以通过GC-PDCCH发送,以用于指示一个或者多个slot的格式。例如,基站可通过GC-PDCCH中承载的SFI改写半静态配置的灵活(flexible)符号或者slot,以灵活地根据实际需求改变符号或者slot的格式,满足不同业务传输需求。
可以理解,前述的flexible符号或者slot是指该符号或者slot的传输方向是待定的。网络可以通过动态信令,如dynamic SFI来对flexible的符号或者slot的传输方向进行修改。
(3)通过高层信令配置包含上行符号和/或灵活(flexible)符号的时间单元。
(4)通过动态信令SFI指示的包含有上行符号和/或灵活的时间单元。
相应的,在所述目标时间窗包括至少一个下行时间单元时,所述下行时间单元也可以为以下(1)-(4)中至少一项。
(1)通过高层信令配置为下行时间单元的时间单元。
(2)通过动态信令SFI指示为下行时间单元的时间单元。
(3)通过高层信令配置包含下行符号和/或灵活符号的时间单元。
(4)通过动态信令SFI指示的包含有下行符号和/或灵活符号的时间单元。
其中,与上行时间单元类似,前述(1)-(4)中所述的下行时间单元的实现可参照前述对上行时间单元的描述,为避免重复,本实施例对此不再赘 述。
进一步,考虑到所述目标时间窗的不同,下面结合示例1至示例3,对不同目标时间窗对应的所述目标反馈信息进行说明,内容如下。
示例1,在所述目标时间窗为绝对时间的情况下,所述目标反馈信息可以为以下(1)和(2)中的任一项。
(1)在指定时间之前的第一时长内反馈的反馈信息。
其中,所述第一时长可以根据所述绝对时间确定,例如,所述绝对时间为4ms,根据所述绝对时间确定的所述第一时长为4ms。另外,所述指定时间可以包括以下(a)-(j)中的任一项。
(a)目标DCI的起始时间或结束时间。一种实现方式中,所述目标DCI可以是指用于传输所述反馈指示信息的DCI,也可以是用于确定所述目标时间窗的DCI等,在此不做限制。
(b)所述目标DCI所在时间单元的起始时间或结束时间。
(c)所述目标DCI调度的第一上行传输的起始时间或结束时间。其中,所述第一上行传输可以包括PUCCH或PUSCH。
(d)所述目标DCI调度的第一上行传输所在时间单元的起始时间或结束时间。
(e)所述目标DCI调度的下行传输的起始时间或结束时间。
(f)所述目标DCI调度的下行传输所在时间单元的起始时间或结束时间。
(g)第二上行传输的起始时间或结束时间。其中,所述第二上行传输可以为SPS PDSCH场景下,用于反馈SPS PDSCH HARQ-ACK的PUCCH等。
(h)第二上行传输所在时间单元的起始时间或结束时间。
(i)第二下行传输的起始时间或结束时间,其中,所述第二下行传输可以包括SPS PDSCH场景下的SPS PDSCH。
(j)第二下行传输所在时间单元的起始时间或结束时间。
(2)在指定时间之前的所述第一时长内接收到的所述第一下行传输对应 的反馈信息。其中,关于(2)中所述的目标反馈信息可参照前述(1)中的详细描述,为避免重复,在此不再赘述。
示例2,在所述目标时间窗包括至少一个时间单元的情况下,所述目标反馈信息为以下(1)和(2)中任一项。
(1)指定时间单元之前的第一数量个时间单元内反馈的反馈信息。
其中,所述第一数量可以根据所述目标时间窗包括的时间单元的数量确定。例如,所述目标时间窗包括5个时间单元,那么所述第一数量为5。一种实现方式中,所述指定时间单元包括以下(a)-(d)中的任一项。
(a)目标DCI对应的目标符号所属的时间单元。其中,所述目标符号为起始符号或结束符号。
(b)所述目标DCI调度的第一上行传输对应的时间单元。其中,所述第一上行传输可以包括PUCCH或PUSCH。
(c)所述目标DCI调度的第一下行传输的起始时间或结束时间。
(d)所述目标DCI所属的时间单元。
(2)指定时间单元之前的第一数量个时间单元内接收到的所述第一下行传输对应的反馈信息。其中,关于(2)中所述的目标反馈信息可参照前述(1)中的详细描述,为避免重复,在此不再赘述。
示例3,在所述目标时间窗是通过配置或指示的时间单元的数量确定的情况下,所述目标时间窗可以是相对于当前DCI(也即,目标DCI)所对应的上行时间单元或者调度的PUCCH/PUSCH的时间单元向前偏移的时间单元数至当前DCI所对应的上行时间单元间包含的时间单元(可以不包含当前DCI所对应的上行时间单元),还可以是高层配置(如RRC配置)的时间单元偏移列表,该时间单元偏移列表中的每一项包含一个或多个时间单元数,再结合DCI指示高层配置的时间单元偏移列表中的一项或多项。
示例性,假设所述目标反馈信息为HARQ-ACK,请结合参阅图4,基站(也即网络设备)通过RRC配置的时间单元偏移列表可以包含三项:{0}、 {1,2}、{3,4},目标DCI中包含2比特,如00、01、10、11,以分别用于指示没有触发指示时间窗内的HARQ-ACK反馈,触发终端反馈目标DCI向前偏移时隙{0},{1,2},{3,4}内的HARQ-ACK反馈。
一种实现方式中,如图4所示,假设如PUCCH1由于某些原因未能成功传输,对此,基站可在时隙n通过PDCCH4承载目标DCI以触发终端反馈。其中PDCCH4包含相关指示域,如触发域并指示为“11”(即图4中所示的T=11),基于前述内容可知,该“11”对应时间单元偏移列表中的{3,4},也就是,触发终端反馈某个参考时间之前偏移{3,4}个时间单元的HARQ-ACK,如以目标DCI所在时间单元为参考时间,则表示触发PDCCH4所在时隙向前偏移{3,4}时隙(即时隙n-4和时隙n-3)内的HARQ-ACK反馈,即PUCCH1反馈的HARQ-ACK。由此可知,终端可在时隙n+1反馈PUCCH1对应HARQ-ACK(即目标反馈信息)以及PDSCH4对应的HARQ-ACK。
此外,需要注意的是,RRC或DCI配置/指示的是目标时间窗的起始时间/时间单元和/或时间长度,或者是时间窗结束时间/时间单元。例如RRC配置时间窗为{1,4},则可以理解为:触发参考时间,如目标DCI起始/结束符号所对应的上行时间单元n之前的n-4时间单元至n-1时间单元反馈的HARQ-ACK,即图4中所示的时隙n-4至时隙n-1反馈的HARQ-ACK,也就是,PUCCH1和PUCCH2上反馈的HARQ-ACK。
又例如,如果RRC配置的时间窗为{S,L},触发参考时间,如目标DCI所在时间单元为n,则目标反馈信息为时间单元n-S-L+1至n-S之间反馈的HARQ-ACK。需要注意的是,本申请所述的目标时间窗的配置方式可以是但不限于上述配置方式。
进一步,作为本申请的一种可能的实现方式,前述的目标反馈信息可以为具有指示标识的反馈信息,其中,所述指示标识可以是通过目标DCI指示;或者,所述指示标识与所述目标DCI调度的PDSCH的HARQ-ACK或所述DCI对应的HARQ-ACK对应的标识相同。其中,所述指示标识包括码本索 引或/和优先级信息。例如,终端传输的目标反馈信息可以为特定码本索引/优先级对应的HARQ-ACK。
另外,在所述目标反馈信息为触发第一上行传输之前的第二时长(如T)内调度的第一下行传输对应的反馈信息的情况下,所述第一下行传输为满足预设的处理时间的下行传输。
例如,在所述第一下行传输为调度的PDSCH的情况下,通过反馈指示信息触发终端传输n-X时间单元至n-1时间单元内调度的且满足PDSCH处理时间的PDSCH对应的反馈信息。其中,该PDSCH处理时间可以根据预定义规则确定,在此不再赘述。
S320,在所述反馈指示信息指示所述终端传输所述目标反馈信息的情况下,传输所述目标反馈信息。
其中,S320的具体实现方式除可参照前述S220的描述之外,作为一种可能的实现方式,终端传输所述目标反馈信息的过程可以包括:在所述目标DCI调度了目标PDSCH的情况下,将所述目标反馈信息和所述目标PDSCH对应的反馈信息在同一时域资源上传输。或者,在所述目标DCI本身需要反馈HARQ-ACK的情况下(例如所述目标DCI为释放SPS PDSCH的DCI,或所述目标DCI为指示辅小区(Scell)进入睡眠状态的DCI等),将所述目标反馈信息和所述目标DCI对应的反馈信息在同一时域资源上传输。
作为另一种可能的实现方式,在所述目标反馈信息中存在重复反馈的多个第一反馈信息的情况下,传输至少一个所述第一反馈信息,以及所述目标反馈信息中除多个所述第一反馈信息之外的其他反馈信息。其中,所述至少一个所述第一反馈信息可以是通过预定义的方式确定的,例如多个所述第一反馈信息中的第一个所述第一反馈信息、最后一个第一反馈信息等。
示例性的,假设目标反馈信息为ABA,由于ABA中存在重复反馈的两个A,为避免资源浪费,同时提高传输效率,可仅反馈B和一个A,也就AB,或BA。
需要注意的是,在前述的反馈信息传输方法300中,终端在传输所述目标反馈信息之前,在所述目标反馈信息为多个的情况下,可以执行以下(1)-(4)中的至少一项。
(1)按照各所述目标反馈信息的反馈时间顺序(从早到晚、或从晚到早等)对所述各所述目标反馈信息进行排序。
(2)按照目标小区索引对所述各所述目标反馈信息进行排序,所述目标小区索引为所述目标反馈信息对应的下行传输所属的服务小区的索引。
(3)按照各所述目标反馈信息对应的下行传输的传输时间顺序对各所述目标反馈信息进行排序。
(4)对各所述目标反馈信息进行级联。其中,各目标反馈信息级联时的先后顺序不做限制。
基于本实施例给出的前述反馈信息传输方法300,下面结合图5a、5b、5c所述反馈信息传输方法300的实现过程进行说明。
如图5a所示,假设PDSCH1、PDSCH2为动态调度的下行传输PDSCH,根据其对应的调度DCI的指示,其分别对应的HARQ-ACK(反馈信息)在时隙n-2的PUCCH1上反馈。PDSCH3为SPS PDSCH,根据其激活DCI的指示,其对应的HARQ-ACK在时隙n-1的PUCCH2上反馈。但是,在时隙n-2上,由于有比PUCCH1的优先级高的PUSCH传输,导致PUCCH1的传输被取消。同时,在时隙n-1,由于半静态上下行TDD配置或SFI指示等,PUCCH2的部分符号或全部符号,与半静态上下行TDD配置的下行符号或与SFI指示的下行符号或灵活符号冲突,导致PUCCH2传输被取消或无法传输。因此PDSCH1、PDSCH2和PDSCH3分别对应的HARQ-ACK均无法发送给基站(也即网络设备)。
对此,在本实施例中,为了确保PUCCH1和PUCCH2的有效传输,基站可以通过高层信令等配置一个目标时间窗,如指示时间单元(如时隙)的数量或者绝对时间长度等(例如通过RRC配置目标时间窗为4个时隙)。其 中PDCCH4调度PDSCH4并指示其对应的HARQ-ACK在时隙n反馈,并触发终端传输目标时间窗内的HARQ-ACK,其触发可以是DCI中包含1比特显示触发,或其他方式隐式触发。那么,终端在接收到承载有触发信息的PDCCH4之后,传输目标时间窗内的HARQ-ACK,则表示终端在时隙n+1,除了要传输PDSCH 4的HARQ-ACK之外,还需要传输目标时间窗内的HARQ-ACK(也即目标反馈信息)。例如,假设第一数量为4,那么,目标反馈信息可以包括以下至少一项。
(1)目标DCI所在时间单元之前的第一数量(如4)的时间单元内反馈的HARQ-ACK。即图5a中,时隙n-4至时隙n-1(目标时间窗)内反馈的HARQ-ACK,如PUCCH1和PUCCH2上反馈的HARQ-ACK。
(2)目标DCI所在时间单元之前的第一数量的时间单元内调度的下行传输对应的HARQ-ACK,即图5a中,时隙n-4至时隙n-1(目标时间窗)内调度的PDSCH对应的HARQ-ACK,如PDSCH1、PDSCH2和PDSCH3对应的HARQ-ACK。
(3)目标DCI调度的第一上行传输对应的时间单元之前的第一数量个时间单元内反馈的HARQ-ACK,即图5a中,时隙n-3至时隙n反馈的HARQ-ACK,如PUCCH1和PUCCH2上反馈的HARQ-ACK。
(4)目标DCI调度的第一上行传输所在时间单元之前的第一数量的时间单元内调度的下行传输对应的HARQ-ACK,即图5a中,时隙n-3至时隙n内调度的PDSCH对应的HARQ-ACK,如PDSCH3对应的HARQQ-ACK。
(5)目标DCI对应的目标符号(如结束符号或开始符号)所属的时间单元之前的第一数量个时间单元内反馈的HARQ-ACK。参阅图5a,假设目标DCI对应的结束符号或开始符号所属的时间单元为n,基于此,终端传输时隙n-4至时隙n-1内的HARQ-ACK,如PUCCH1和PUCCH2上反馈的HARQ-ACK。
(6)目标DCI对应的目标符号所属的时间单元之前的第一数量个时间 单元内接收到的所述第一下行传输对应的HARQ-ACK。参阅图5a,假设目标DCI对应的结束符号或开始符号所属的时间单元为n,基于此,终端传输时隙n-4至时隙n-1内调度的PDSCH对应的HARQ-ACK,如PDSCH1、PDSCH2和PDSCH3对应的HARQ-ACK。
(7)所述目标DCI调度的第一上行传输对应的时间单元之前的第一数量个时间单元内接收到的所述第一下行传输对应的HARQ-ACK。即图5a中,时隙n-3至时隙n内调度的PDSCH对应的HARQ-ACK,如PDSCH3、PDSCH4对应的HARQ-ACK。
(8)所述目标DCI调度的第一下行传输的起始时间或结束时间之前的第一数量个时间单元内反馈的HARQ-ACK。参阅图5a,假设目标DCI调度的第一下行传输的起始时间或结束时间之前的第一数量个时间单元为时隙n-4至时隙n-1,那么,目标反馈信息即为PUCCH1和PUCCH2上反馈的HARQ-ACK
(9))所述目标DCI调度的第一下行传输的起始时间或结束时间之前的第一数量个时间单元内接收到的所述第一下行传输对应的HARQ-ACK。参阅图5a,假设目标DCI调度的第一下行传输的起始时间或结束时间之前的第一数量个时间单元为时隙n-4至时隙n-1,那么,目标反馈信息即为PDSCH1、PDSCH2和PDSCH3对应的HARQ-ACK。
应注意,终端在传输时,可能存在多个HARQ-ACK(即目标反馈信息),对此,可以将PDSCH1、PDSCH2和PDSCH3分别对应的HARQ-ACK按照时间顺序或服务小区索引或PDSCH接收时间等顺序排列,或者还可以将PUCCH1的HARQ-ACK码本与PUCCH2的HARQ-ACK码本进行级联,并将PDSCH4的HARQ-ACK信息放在级联后的码本的前面/后面,最后基于排序或级联后的多个HARQ-ACK进行反馈信息传输。
其中,当终端被配置生成两个HARQ-ACK codebook,则目标DCI可以指示触发目标时间窗内的哪个codebook对应的HARQ-ACK,例如DCI中有 1比特指示触发的HARQ-ACK的codebook。或者通过其他隐式方式指示,例如DCI格式等。如图5a中,假设,PDSCH1和PDSCH2对应的HARQ-ACK为codebook 1,PDSCH3对应的HARQ-ACK codebook为codebook 0(例如codebook 1对应高优先级,codebook 0对应低优先级,则PUCCH1为高优先级,PUCCH2为低优先级),PDCCH4调度的PDSCH4对应的HARQ-ACK为codebook 1,则当PDCCH4触发终端传输目标时间窗内的HARQ-ACK时,可以表示触发终端传输目标时间窗内的codebook 1对应的HARQ-ACK,或者PDCCH4指示触发哪个/些codebook的HARQ-ACK,或者预定义或高层配置触发的HARQ-ACK codebook。
另一种实现方式中,如果按照上述(1)-(4)中确定的HARQ-ACK信息有重复(多次包含某个PDSCH的HARQ-ACK),则终端可以仅传输一次该HARQ-ACK信息。例如,参阅图5b,基站在PDCCH4中触发终端传输目标时间窗内的HARQ-ACK,但是由于某些突发原因(如高优先级上行传输或者终端间取消指示或者信道接入失败等)导致PUCCH3并未能成功发送,因此,基站在时隙n+2可再次触发终端传输目标时间窗内的HARQ-ACK信息,即图5b中所示的时隙n-2至时隙n+1(目标时间窗)传输的HARQ-ACK,如PUCCH1和PUCCH2以及PUCCH3上反馈的HARQ-ACK,其中,可以将PUCCH1和PUCCH2以及PUCCH3承载的HARQ-ACK信息级联。
但是,由于PDCCH4触发了终端传输目标时间窗内的HARQ-ACK,即PUCCH3已经包含了PUCCH1和PUCCH2上的HARQ-ACK,因此终端在时隙n+2,如果直接将PUCCH1、PUCCH2和PUCCH3对应的HARQ-ACK直接级联,则PDSCH1、PDSCH 2和PDSCH3对应的HARQ-ACK信息包含了两次,对此,终端不需要传输PUCCH1和PUCCH2承载的HARQ-ACK,终端只需要将PUCCH3反馈的HARQ-ACK在时隙n+2再次反馈即可。
另外,如果目标反馈窗内包含PUCCH的多次重复,则该PUCCH承载的HARQ-ACK只需要在触发DCI指示的时间单元内反馈一次。如图5c所示, PDSCH 1~3分别指示在时隙n-2反馈HARQ-ACK,同时对应的PUCCH 1-1配置了重复传输,即PUCCH 1-1和PUCCH 1_2为同一个PUCCH的不同重复,基站可通过PDCCH4触发时间窗n-2和n-1内反馈的HARQ-ACK,则终端只需要传输PUCCH 1_1或PUCCH 1_2对应的HARQ-ACK,即PDSCH1~3对应的3比特HARQ-ACK以及PDSCH4对应的1比特HARQ-ACK在时隙n+2传输即可,而不需要将PUCCH1_1和PUCCH 1_2对应的HARQ-ACK比特级联。
如图6所示,为本申请一示例性实施例提供的反馈信息传输方法600的流程示意图,该方法600可应用但不限于终端,具体可由安装于所述终端中的软件和/或硬件执行,所述方法600至少可以包括如下步骤。
S610,接收反馈指示信息。
所述反馈指示信息用于指示所述终端是否传输目标反馈信息,所述目标反馈信息是所述终端在目标时间窗内反馈的反馈信息,或者,所述目标反馈信息是所述终端在目标时间窗内接收到的第一下行传输对应的反馈信息;
S620,在所述反馈指示信息指示所述终端传输所述目标反馈信息的情况下,传输所述目标反馈信息。
其中,关于S610和S620的实现过程除可参照前述反馈信息传输方法200、300的详细描述之外,本实施例中,所述目标反馈信息包括SPS PDSCH对应的HARQ-ACK信息。可以理解的是,对于SPS PDSCH,网络设备(如基站)可以为每个SPS PDSCH配置一个目标时间窗,如HARQ-ACK反馈窗,在该SPS PDSCH对应的HARQ-ACK反馈窗内,使得终端可以在HARQ-ACK反馈窗内反馈:所述SPS PDSCH对应的HARQ-ACK,和/或指示或配置在HARQ-ACK反馈窗内传输的HARQ-ACK。
一种实现方式中,与前述目标时间窗类似,所述HARQ-ACK反馈窗也可以为时间单元数或绝对时间。另外,所述HARQ-ACK反馈窗为目标PUCCH 所在时间单元之前的第二数量个时间单元;或者,所述HARQ-ACK反馈窗为目标时间之前的第三时长;其中,所述目标PUCCH是用于反馈该SPS PDSCH对应的HARQ-ACK的PUCCH,所述目标时间包括所述目标PUCCH的起始时间、所述目标PUCCH的结束时间、所述目标PUCCH所在的时间单元的起始时间、所述目标PUCCH所在的时间单元的结束时间中的任一个。
示例性的,对于SPS PDSCH,网络配置或指示SPS HARQ-ACK反馈(只反馈SPS PDSCH的HARQ-ACK的PUCCH)对应的HARQ-ACK反馈窗,或HARQ-ACK传输候选窗。
对于一个给定时域位置用于承载SPS HARQ-ACK的PUCCH,该PUCCH包含的HARQ-ACK由HARQ-ACK传输候选窗中对应的HARQ-ACK传输来确定。
可选地,对于HARQ-ACK传输候选窗:如果一个HARQ-ACK或一个承载HARQ-ACK的PUCCH没有发送,则在该PUCCH中包含该HARQ-ACK/该PUCCH承载的HARQ-ACK。
此外,可选地,如果一个HARQ-ACK或一个承载HARQ-ACK的PUCCH已经发送,终端不生成且不在该PUCCH中包含该HARQ-ACK;或者,终端在该PUCCH中包含该HARQ-ACK,本实施对此不做限制。
可以理解是,前述的HARQ-ACK传输候选窗,可以由DCI指示或更新。其中,该DCI为该SPS PDSCH对应的激活DCI,该激活DCI的无线网络标识(Radio Network Temporary Identifier,RNTI)为CS-RNTI,该DCI可以调度PDSCH或不调度PDSCH,所述PUCCH的资源为所述激活DCI所指示的PUCCH资源。
示例性的,如图7a所示,假设SPS PDSCH的周期为1个时隙,时分复用(TDD)上/下行配置为DDDDDDDSUU,激活DCI(即前述的目标DCI)中指示k1=2,即如果终端在时隙n接收到SPS PDSCH,那么,在时隙n+2反馈其HARQ-ACK。但由于TDD上/下行配置,可能导致图7a中所示的SPS  PDSCH1~6分别对应的HARQ-ACK均无法发送给基站。
对此,本实施例中,基站可以给SPS PDSCH配置或者在激活DCI中指示一个HARQ-ACK反馈窗(即目标时间窗),终端每次反馈一个SPS PDSCH的HARQ-ACK时,不仅反馈该SPS PDSCH的HARQ-ACK,还可传输目标时间窗口内的HARQ-ACK。例如,图7b中该SPS PDSCH对应的PUCCH的HARQ-ACK反馈窗可配置为{3,4,5,6},即终端在时间单元n反馈HARQ-ACK时,还需要反馈n之前时间单元{n-6,n-5,n-4,n-3}反馈的HARQ-ACK,即图7b中PDSCH1~4分别对应的HARQ-ACK。
另外,图7b中,如果终端还接收到一个下行调度(DL grant),其调度了一个PUCCH,并指示了一个HARQ-ACK反馈窗为{1,2,3},即终端需要反馈DL调度的PUCCH所在时间单元之前3~1个时间单元内反馈的HARQ-ACK,即图7b中所示的PDSCH5~7,以及PDSCH 1~4分别对应的HARQ-ACK。其中,终端在PUCCH2上反馈HARQ-ACK时,其HARQ-ACK比特可以按照PDSCH的接收时间顺序,或者按照反馈时间窗内的PUCCH承载的HARQ-ACK的比特级联的方式构建HARQ-ACK码本。
如图8所示,为本申请一示例性实施例提供的反馈信息传输方法800的流程示意图,该方法800可应用但不限于网络设备,具体可由安装于所述网络设备中的软件和/或硬件执行,所述方法800至少可以包括如下步骤。

其中,所述反馈指示信息用于指示终端是否传输目标反馈信息,所述目标反馈信息是所述终端在目标时间窗内反馈的反馈信息,或者,所述目标反馈信息是所述终端在目标时间窗内接收到的第一下行传输对应的反馈信息。
关于S810的具体实现过程可参阅S210和S310中的详细描述,为避免重复,本实施例对此不再赘述。
本实施例提供的反馈信息传输方法800中,网络设备通过发送反馈指示 信息给终端,以指示终端是否传输目标反馈信息,其中,所述目标反馈信息是所述终端在目标时间窗内反馈的反馈信息,或者,所述目标反馈信息是所述终端在目标时间窗内接收到的第一下行传输对应的反馈信息,由此,能够使得终端根据接收到的反馈指示信息进行目标反馈信息的反馈,有效提高了目标反馈信息的反馈机会,解决了由于反馈信息与DL符号冲突而被丢弃,或者与高优先级的信道/信号冲突而被取消传输,导致的反馈信息无法传输至网络设备的问题,确保通信性能。
