技术领域
本公开涉及通信或终端领域,尤其涉及一种HARQ-ACK反馈时间的确定方法和指示方法、终端设备和网络设备。
背景技术
在新无线(New Radio,NR)***中,基站在调度下行传输时,可以采用动态调度的方式,也可以采用半持续的调度方式,其中,在采用动态调度的方式时,每次调度都需要调度信令的交互,因此,会导致调度信令有很大的开销;而在采用半持续调度时,可以只在初次调度时进行调度信令的交互,后续可以根据该初次调度时交互的调度信令来进行周期性的调度,由于不需要在每次调度时都进行调度信令的交互,因此,半持续的调度方式可以减小调度信令的开销,故相关技术中,基站在调度周期性发送且格式较固定的数据时,通常采用半持续的调度方式来进行调度。
但是,当基站采用动态调度的方式来调度下行传输时,由于可以在每次调度时均进行下行控制信息(Downlink Control Information,DCI)信令的交互(DCI信令可以用于指示用户端(User Equipment,UE)接收到数据后的混合自动重传请求确认(Hybrid Automatic Repeat request Acknowledgement,HARQ-ACK)反馈时间,故可以在每次下行调度时,配置UE接收到下行数据后的HARQ-ACK反馈时间;而当基站采用半持续调度的方式进行下行调度时,由于在非初次调度的情况下,一般不进行DCI信令的交互,因此,在非初次的每次调度时,相关技术无法对UE接收到下行数据后的HARQ-ACK反馈时间进行配置。

以下结合附图,详细说明本公开各实施例提供的技术方案。
图1是本公开的一个实施例中一种HARQ-ACK反馈时间的确定方法的流程图。该实施例中,HARQ-ACK反馈时间的确定方法应用于终端设备。图1所示的方法可包括:步骤101至103。
步骤101:接收目标信令,目标信令携带有HARQ-ACK反馈时间参数。
在本公开实施例中,终端设备可以配置下行半持续调度,具体地,终端设备可以基于高层信令,例如RRC(Radio Resource Control,无线资源控制) 信令,来进行下行半持续调度配置,在配置了下行半持续调度后,终端设备当前可以处于半持续调度配置未激活的状态,此时,终端设备可以基于接收到的下行控制信令,例如,DCI信令,来对该未激活的半持续调度配置进行激活。
在本公开实施例中,终端设备可以接收网络设备,例如,基站,发送的目标信令,其中,该目标信令中携带有HARQ-ACK反馈时间参数。
在一个实施例中,上述高层信令或上述下行控制信令携带有HARQ-ACK反馈时间参数,即上述高层信令或上述下行控制信令可以为目标信令。
在一个示例中,若上述下行控制信令中携带有HARQ-ACK反馈时间参数,则可以确定上述下行控制信令为目标信令;若上述下行控制信令中未携带有HARQ-ACK反馈时间参数,上述高层信令中携带有HARQ-ACK反馈时间参数,则可以确定上述高层信令为目标信令。
在一个实施例中,目标信令携带的HARQ-ACK反馈时间参数可以为一个反馈时间间隔,也可以为一个反馈时间间隔区间。例如,目标信令携带的HARQ-ACK反馈时间参数可以为时隙K,也可以为时隙[M,N](N大于M)。
在一个实施例中,目标信令携带的HARQ-ACK反馈时间参数可以用于指示一个反馈时间间隔,或用于指示一个反馈时间间隔区间。
例如,目标信令携带的HARQ-ACK反馈时间参数可以为从一个集合中选择的,该集合可以是高层信令配置的,或者是预定义的。
需要说明的是,当目标信令为上述高层信令时,其携带的HARQ-ACK反馈时间参数可以用于指示一个反馈时间间隔,或用于指示一个反馈时间间隔区间。
在本公开实施例中,当目标信令为上述下行控制信令时,该下行控制信令存储上述HARQ-ACK反馈时间参数的字段与动态调度时下行控制信令中存储HARQ-ACK反馈时间参数的字段相同,或者,当目标信令为上述下行控制信令时,该下行控制信令中存储上述HARQ-ACK反馈时间参数的字段为新增的字段。
在本公开实施例中,当目标信令为上述下行控制信令时,该目标信令可以为该终端设备接收到的最新的下行控制信令,例如,该目标信令可以具体 为该终端设备接收到为离SPS(Semi-Persistent Scheduling,半静态调度)PDSCH(Physical Downlink Shared Channel,物理下行共享信道)之前最近的DCI信令,其中,
步骤102:在第一时域资源接收下行传输的半持续调度数据。
在本公开实施例中,第一时域资源可以采用帧、子帧、时隙或符号表示。

步骤103:基于HARQ-ACK反馈时间参数,以及第一时域资源,确定下行传输的半持续调度数据的HARQ-ACK反馈时间。
在本公开实施例中,该终端设备在接收到目标信令以及在第一时域资源接收到下行传输的半持续调度数据后,可以基于目标信令中的HARQ-ACK反馈时间参数,以及上述第一时域资源来确定上述下行传输的半持续调度数据的HARQ-ACK反馈时间。
在一个示例中,目标信令携带的HARQ-ACK反馈时间参数可以为反馈时间间隔,或反馈时间间隔区间,则目标信令可以基于第一时域资源以及该反馈时间间隔,或反馈时间间隔区间来确定下行传输的半持续调度数据的HARQ-ACK反馈时间。
例如,目标信令携带的HARQ-ACK反馈时间参数可以为时隙数K,若该终端设备在时隙H接收到下行传输的半持续调度数据,则该终端设备基于目标信令中的HARQ-ACK反馈时间参数,以及上述第一时域资源确定的上述下行传输的半持续调度数据的HARQ-ACK反馈时间为时隙K+H。
再例如,目标信令携带的HARQ-ACK反馈时间参数可以为时隙数的范围[M,N],若该终端设备在时隙H接收到下行传输的半持续调度数据,则该终端设备基于目标信令中的HARQ-ACK反馈时间参数,以及上述第一时域资源确定的上述下行传输的半持续调度数据的HARQ-ACK反馈时间为时隙[H+M,H+N]中之一。
在一个示例中,目标信令携带的HARQ-ACK反馈时间参数可以用于指示反馈时间间隔,或反馈时间间隔区间的位置数据信息,例如,可以为反馈 时间间隔或反馈时间间隔区间在上述时间集合中的位置数据信息。此时,该终端设备可以先基于该HARQ-ACK反馈时间参数从上述时间集合中确定反馈时间间隔,或反馈时间间隔区间,然后,终端设备可以基于第一时域资源以及该确定的反馈时间间隔,或反馈时间间隔区间来确定下行传输的半持续调度数据的HARQ-ACK反馈时间。
在一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔,则该终端设备可以基于该反馈时间间隔以及上述第一时域资源,确定第一HARQ-ACK反馈时间,如果该第一HARQ-ACK反馈时间的时域资源格式与半静态或动态的上下行配置指示的时域资源格式不存在冲突,则将第一HARQ-ACK反馈时间确定为HARQ-ACK反馈时间。
应理解,时域资源格式,包括上行、下行和传输未定三种,其它实施例中的时域资源格式与此相同。
在另一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔,则该终端设备可以基于该反馈时间间隔以及上述第一时域资源,确定第二HARQ-ACK反馈时间,如果该第二HARQ-ACK反馈时间的时域资源格式与半静态或动态的上下行配置指示的时域资源格式存在冲突,则将该第二HARQ-ACK反馈时间之后的最近可用的上行时刻确定为HARQ-ACK反馈时间,其中,上行时刻可以为上行时隙,或上行符号。
在再一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔,则该终端设备可以基于该反馈时间间隔以及上述第一时域资源,确定第三HARQ-ACK反馈时间,如果第三HARQ-ACK反馈时间的时域资源格式与半静态或动态的上下行配置指示的时域资源格式存在冲突,将所述第二时域资源确定为HARQ-ACK反馈时间,其中,第二时域资源为第三HARQ-ACK反馈时间之后传输方向未定的最近的可用的时域资源。该传输方向未定的最近的可用的时域资源已经配置了物理上行链路控制信道PUCCH资源,且调度或配置了物理上行共享信道PUSCH传输。
在再一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔区间,则该终端设备可以基于该反馈时间间隔区间以及上述第一时域资源,确定第四HARQ-ACK反馈时间,如果该第四HARQ-ACK反馈 时间的时域资源格式与半静态或动态的上下行配置指示的时域资源格式不存在冲突,则将第四HARQ-ACK反馈时间确定为所述HARQ-ACK反馈时间。
在再一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔区间,则该终端设备可以基于该反馈时间间隔区间以及上述第一时域资源,确定第五HARQ-ACK反馈时间和第一HARQ-ACK反馈时间区间,如果第五HARQ-ACK反馈时间的时域资源格式与半静态或动态的上下行配置指示的时域资源格式存在冲突,且所述第一HARQ-ACK反馈时间区间中的至少一个时域资源的时域资源格式与半静态和动态的上下行配置不存在冲突,则将所述至少一个时域资源之一确定为所述HARQ-ACK反馈时间。
在再一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔区间,则该终端设备可以基于该反馈时间间隔区间以及上述第一时域资源,确定第六HARQ-ACK反馈时间和第二HARQ-ACK反馈时间区间,如果第二HARQ-ACK反馈时间区间中的时域资源的时域资源格式与半静态或动态中的上下行配置指示的时域资源格式都存在冲突,则将第二HARQ-ACK反馈时间区间之后的最近可用的上行时刻确定为HARQ-ACK反馈时间,其中,上行时刻可以为上行时隙,或上行符号。
在再一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔区间,则该终端设备可以基于该反馈时间间隔区间以及上述第一时域资源,确定第七HARQ-ACK反馈时间和第三HARQ-ACK反馈时间区间,如果第三HARQ-ACK反馈时间区间中的时域资源的时域资源格式与半静态或动态中的上下行配置指示的时域资源格式都存在冲突,将第二时域资源确定为HARQ-ACK反馈时间,其中,第二时域资源为该第三HARQ-ACK反馈时间区间之后传输方向未定的最近的可用的时域资源,该传输方向未定的最近的可用的时域资源已经配置了物理上行链路控制信道PUCCH资源,且调度或配置了PUSCH传输。
在再一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔,则该终端设备可以基于该反馈时间间隔以及上述第一时域资源,确定第八HARQ-ACK反馈时间,如果第八HARQ-ACK反馈时间的时域资源格式与半静态或动态中的上下行配置指示的时域资源格式存在冲突,则 放弃反馈HARQ-ACK。
在再一个实施例中,若目标信令中携带的HARQ-ACK反馈时间参数为反馈时间间隔区间,则该终端设备可以基于该反馈时间间隔区间以及上述第一时域资源,确定第九HARQ-ACK反馈时间以及第四HARQ-ACK反馈时间区间,如果第九ARQ-ACK反馈时间的时域资源格式与半静态或动态中的上下行配置指示的时域资源格式存在冲突,则放弃反馈HARQ-ACK。
在本公开的实施例中,终端设备也可以根据上述第一时域资源以及协议中携带的固定值来确定HARQ-ACK反馈时间,本公开实施例对该携带固定值的协议不做限定。
在本公开实施中,若该终端设备接收到聚合的PDSCH,则终端设备在确定HARQ-ACK反馈时间时,可以基于接收聚合的PDSCH的接收时间区间以及自身的业务处理能力来确定。
例如,该终端设备可以在时隙集[N,N+K]接收聚合的PDSCH,且该终端设备确定的自身业务处理能力为至少H个时隙,则HARQ-ACK反馈时间为时隙集[N+H,N+K+H]中之一。
例如,该终端设备可以在时隙集[N,N+K]接收聚合的PDSCH,且该终端设备确定的自身业务处理能力为至少H个时隙,但S+K大于H个时隙,T大于H个时隙,则HARQ-ACK反馈时间可以为[N+H+S,N+K+T]中之一,其中,S、T可以由上述目标信令中携带的HARQ-ACK反馈时间参数基于上述实施例来确定。
在本公开实施例中,上述确定的下行传输的半持续调度数据的HARQ-ACK反馈时间可以采用帧、子帧、时隙或符号表示。
在本公开实施例中,终端设备可以接收目标信令,其中,该目标信令携带有HARQ-ACK反馈时间参数;然后,终端设备可以在第一时域资源接收下行传输的半持续调度数据,并基于该HARQ-ACK反馈时间参数以及该第一时域资源,来确定下行传输的半持续调度数据的HARQ-ACK反馈时间。
由此可知,本实施例中,终端设备可以通过目标信令携带的HARQ-ACK反馈时间参数,以及第一时域资源来实现在半持续调度且非初次调度的情况下,对终端设备接收到下行传输的半持续调度数据的HARQ-ACK反馈时间 的配置,从而有效解决了相关技术的问题。
