Description

HARQ反馈方法、装置、用户设备和基站 技术领域
本公开涉及通信技术领域,尤其涉及一种混合自动重传请求(HARQ)反馈方法及装置、发送指示信息的方法及装置、用户设备、基站和计算机可读存储介质。
背景技术
随着通信技术的发展,出现了第五代移动通信技术(5th Generation,简称5G)。5G目前的业务类型至少包括增强移动宽带(enhanced Mobile Broad Band,简称eMBB)、海量机器类通信(massive Machine Type Communication,简称mMTC)、超高可靠与低延迟的通信(Ultra Reliable Low Latency Communication,简称URLLC)等多种类型。这些业务同属数据业务,但对时延和可靠性的要求各不相同,例如URLLC业务用于车联网等需要低时延的领域,对及时性要求很高,建立业务时需要及时,甚至对之前的业务具有抢占性。而mMTC业务则通常对时延并不敏感,可以间隔较长时间送达数据。实现对时延敏感业务有效传输的一种方式是改进混合自动重传请求(Hybrid Automatic Repeat reQuest,简称HARQ)的传输,例如,使得重传反馈更快更准确。
长期演进(Long Term Evolution,简称LTE)中是以传输块(Transmission Block,简称TB)为单位进行HARQ反馈,每个TB反馈1比特(bit)的应答(ACK)或者非应答(NACK)消息。为了提高重传准确率,第三代合作伙伴计划(3GPP)提出基于代码块组(Code Block Group,简称CBG)进行重传,CBG是TB中更小的数据单元单位,一个CBG对应1bit的ACK或者NACK反馈,由于重传的颗粒度将更小,因此可以更精确地反映错误传输的位置,进而使得重传更准确,而由于需要重传的数据量更小,因此,重传效率更高。
但是,如果出现业务抢占(preemption)的情况,例如,当eMBB业务已经开始传输或即将开始传输时,URLLC业务来临,则URLLC会抢占eMBB的传输时频资源,导致原有eMBB业务在HARQ反馈时错误地认为eMBB数据传输错误,从而丢弃有用的URLLC数据。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
图1是本申请一示例性实施例示出的一种HARQ反馈方法的流程图,该实施例从UE侧进行描述,如图1所示,该HARQ反馈方法包括以下步骤:
在步骤S101中,接收基站发送的第一业务数据传输,该第一业务数据传输的调度控制数据中携带指示信息,该指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。
在该实施例中,第二业务相对于第一业务对及时性要求更高,因此,第二业务数据可以抢占第一业务数据。其中,第一业务可以包括但不局限于eMBB,第二业务可以包括但不局限于URLLC。
当UE接收到基站发送的一次第一业务数据传输时,该指示信息可以携带在该次第一业务数据传输的调度控制数据中,该指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。当UE接收到基站发送的两次第一业务数据传输时,该指示信息可以携带在后一次第一业务数据传输的调度控制数据中,该指示信息用于显性指示或隐性指示前一次第一业务数据传输中第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。其中,调 度控制数据可以包括但不局限于物理下行控制信道(PDCCH)。需要说明的是,后一种情况下,两次第一业务数据传输的时间间隔小于非自容HARQ反馈方式的传输时延,否则,在后一次第一业务数据传输的调度控制数据来之前就要向基站发送HARQ反馈信息,即UE未接收到指示信息就需要向基站发送HARQ反馈信息。
在步骤S102中,根据该指示信息,将抢占传输资源的第二业务数据保留在缓存中,并生成第一业务数据的HARQ反馈信息。
在该实施例中,可以根据该指示信息将抢占传输资源的第二业务数据保留在缓存中,以用于第二业务数据的传输。
其中,可以通过多种方式生成第一业务数据的HARQ反馈信息,例如,可以根据除抢占传输资源的第二业务数据之外的数据传输成败状态生成第一业务数据的HARQ反馈信息,又例如,可以将抢占传输资源的第二业务数据的传输成败状态设置为传输成功,并根据第一业务数据传输中所有数据的传输成败状态生成HARQ反馈信息。
通过上述方式生成的HARQ反馈信息可以正确地反映第一业务数据的传输成败状态,从而可以避免UE错误的操作。
在步骤S103中,向基站发送HARQ反馈信息。
在该实施例中,当指示信息携带在后一次第一业务数据传输的调度控制数据中时,可以以非自容HARQ反馈方式向基站发送HARQ反馈信息。
上述实施例,通过根据接收的第一业务数据传输中携带的指示信息,将抢占传输资源的第二业务数据保留在缓存中,使得第一业务数据传输过程中不会丢弃有用的第二业务数据。
图2是本申请一示例性实施例示出的一种发送指示信息的方法的流程图,该实施例从基站侧进行描述,如图2所示,该发送指示信息的方法包括以下步骤:
在步骤S201中,判断是否存在第二业务数据抢占第一业务数据的传输资源。
其中,第一业务可以包括但不局限于eMBB,第二业务可以包括但不局限于URLLC。由于第二业务相对于第一业务对及时性要求更高,因此,第二业务数据可以抢占第一业务数据。在该实施例中,基站可以判断是否存在第二业务数据抢占第一业务数据的传输资源。
在步骤S202中,若存在第二业务数据抢占第一业务数据的传输资源,则向UE发送第一业务数据传输,第一业务数据传输的调度控制数据中携带指示信息,指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务 数据的传输资源位置,以用于UE根据第一指示信息向基站发送第一业务数据的HARQ反馈信息。
在该实施例中,若基站确定存在第二业务数据抢占第一业务数据的传输资源,则可以在向UE发送的第一业务数据传输的调度控制数据中携带指示信息,该指示信息可以显性地指示,例如可以直接增加若干比特(bit)的指示信息,也可以隐性地指示,例如,将指示信息以扰码的形式加扰到调度控制数据中的目标控制信息上,即对部分原有控制信息加扰携带相应的指示信息。该指示信息可以用于指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置,其中,可以采用位图(bitmap)的形式指示上述传输资源位置。UE在接收到该指示信息,可以根据指示信息将抢占传输资源的第二业务数据保留在缓存中,并向基站发送第一业务数据的HARQ反馈信息。
其中,基站向UE发送第一业务数据传输可以包括:基站向UE发送一次第一业务数据传输,这种情况下,指示信息可以携带在该次第一业务数据传输的调度控制数据中,该指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。
另外,基站向UE发送第一业务数据传输还可以包括:基站向UE发送两次第一业务数据传输,这种情况下,该指示信息可以携带在后一次第一业务数据传输的调度控制数据中,该指示信息用于显性指示或隐性指示前一次第一业务数据传输中第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。
其中,调度控制数据可以包括但不局限于物理下行控制信道(PDCCH)。
需要说明的是,后一种情况下,两次第一业务数据传输的时间间隔小于非自容HARQ反馈方式的传输时延,否则,在后一次第一业务数据传输的调度控制数据来之前就要向基站发送HARQ反馈信息,即UE未接收到指示信息就需要向基站发送HARQ反馈信息,即UE无法根据指示信息避免错误的操作。
上述实施例,通过在确定存在第二业务数据抢占第一业务数据的传输资源时,向UE发送携带指示信息的第一业务数据传输,以通知UE第二业务数据抢占第一业务数据的传输资源,从而使UE可以避免错误的操作。
图3是本申请一示例性实施例示出的一种HARQ反馈方法的信令流程图,该实施例从UE和基站交互的角度进行描述,为了更清楚地描述二者的交互过程,该实施例结合图4进行描述,图4示出了一次eMBB传输过程中携带指示信息的示意图,如图4所示,这次eMBB 数据传输的PDCCH中携带指示信息,如图3所示,该HARQ反馈方法包括以下步骤:
在步骤S301中,基站确定存在URLLC数据抢占eMBB数据的传输资源,则向UE发送一次eMBB数据传输,该次eMBB数据传输的PDCCH中携带指示信息。
其中,该指示信息可以用于显性指示URLLC数据抢占eMBB数据的传输资源或者URLLC数据抢占eMBB数据的传输资源位置。
在步骤S302中,UE接收基站发送的eMBB数据传输,并根据eMBB数据传输的PDCCH中携带的指示信息将抢占传输资源的URLLC数据保留在缓存中,并生成eMBB数据的HARQ反馈信息。
其中,当该指示信息显性地指示URLLC数据抢占eMBB数据的传输资源时,UE可以将所有传输失败的数据均保留在缓存中,从保留的数据中识别出传输失败的eMBB数据,并根据传输失败的eMBB数据生成HARQ反馈信息。
例如,UE可以将所有反馈为NACK的传输资源对应的数据均保留在缓存中,不做擦写(flush),待URLLC的所有数据传输完成后,保留的数据中有用的URLLC数据已经被使用,如果除了被使用的数据仍有余下的数据,则说明这些数据是真正的传输失败的数据,UE可以据此计算HARQ反馈信息。
其中,当该指示信息显性地指示URLLC数据抢占eMBB数据的传输资源位置时,UE可以将抢占传输资源的URLLC数据保留在缓存中,用于传输URLLC数据,其他反馈为NACK的数据均可以擦写掉。另外,UE可以根据除抢占传输资源的URLLC数据之外的数据传输成败状态生成HARQ反馈信息,例如,UE可以根据除代码块组(CBG)4之外的CBG的eMBB数据传输成败状态生成HARQ反馈信息。
在步骤S303中,UE向基站发送eMBB数据的HARQ反馈信息。
在步骤S304中,基站根据接收的HARQ反馈信息向UE重传传输失败的eMBB数据。
可选地,当该指示信息指示第二业务数据抢占第一业务数据的传输资源位置时,基站可以接收UE发送的第一业务数据的HARQ反馈信息,该HARQ反馈信息包括与传输资源位置对应的第二业务数据的HARQ反馈信息和与其他传输资源位置对应的第一业务数据的HARQ反馈信息,并根据与其他传输资源位置对应的第一业务数据的HARQ反馈信息向UE重传传输失败的第一业务数据。也即基站在确定待重传的第一业务数据时,忽略与传输资源位置对应的第二业务数据的HARQ反馈信息,只考虑其他资源位置的第一业务数据的HARQ反馈信息。
例如,基站可以根据图4中除代码块组(CBG)4之外的CBG对应的eMBB数据的HARQ反馈信息确定待重传的eMBB数据。
上述实施例,通过UE和基站之间的交互,使得UE可以获知URLLC数据抢占eMBB数据的传输资源,从而使得UE在eMBB数据传输过程中不会丢弃有用的URLLC数据,且可以向基站正确地反映eMBB数据的传输成败状态,进而使得基站可以重传真正传输失败的eMBB数据。
需要说明的是,对于具备判断第二业务数据抢占第一业务数据能力的基站而言,可以采用图3所示的流程进行HARQ反馈,但是,对于不具备这种判断能力的基站而言,可以利用在后一次第一业务数据传输的PDCCH中携带指示信息来实现,该指示信息可以用于显性指示或隐性指示前一次第一业务数据传输中第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。其中,两次第一业务数据传输可以连续,也可以不连续。
图5是本申请一示例性实施例示出的另一种HARQ反馈方法的信令流程图,该实施例从UE和基站交互的角度进行描述,为了更清楚地描述二者的交互过程,该实施例结合图6进行描述,如图6所示,在后一次eMBB数据传输的PDCCH中携带指示信息,该指示信息可以显性指示前一次eMBB数据传输中URLLC数据抢占eMBB数据的传输资源或者URLLC数据抢占eMBB数据的传输资源位置。如图5所示,该HARQ反馈方法包括以下步骤:
在步骤S501中,基站向UE发送两次eMBB数据传输,其中,两次第一业务数据传输的时间间隔小于非自容HARQ反馈方式的传输时延。
其中,指示信息携带在后一次第一业务数据传输的调度控制数据中。
在步骤S502中,UE接收完所有前一次eMBB数据传输后,读取后一次eMBB数据传输的PDCCH,以获取指示信息。
在步骤S503中,根据获取的指示信息将抢占传输资源的URLLC数据保留在缓存中,并生成eMBB数据的HARQ反馈信息。
上述步骤503生成HARQ反馈信息的过程与步骤S302中生成HARQ反馈信息的过程相同,此处不赘述。
在步骤S504中,UE以非自容HARQ反馈方式向基站发送eMBB数据的HARQ反馈信息。
在步骤S505中,基站根据接收的HARQ反馈信息向UE重传传输失败的eMBB数据。
上述实施例,通过UE和基站之间的交互,使得UE可以从后一次第一业务数据传输的调度控制数据中获取指示信息,并根据该指示信息获知URLLC数据抢占eMBB数据的传输资源,从而使得UE在eMBB数据传输过程中不会丢弃有用的URLLC数据,且可以向基站正确地反映eMBB数据的传输成败状态,进而使得基站可以重传真正传输失败的eMBB数据。
图7是根据一示例性实施例示出的一种HARQ反馈装置的框图,该HARQ反馈装置位于UE中,该HARQ反馈装置包括:接收模块71、保留生成模块72和发送模块73。
接收模块71被配置为接收基站发送的第一业务数据传输,第一业务数据传输的调度控制数据中携带指示信息,指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。
在该实施例中,第二业务相对于第一业务对及时性要求更高,因此,第二业务数据可以抢占第一业务数据。其中,第一业务可以包括但不局限于eMBB,第二业务可以包括但不局限于URLLC。
当UE接收到基站发送的一次第一业务数据传输时,该指示信息可以携带在该次第一业务数据传输的调度控制数据中,该指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。当UE接收到基站发送的两次第一业务数据传输时,该指示信息可以携带在后一次第一业务数据传输的调度控制数据中,该指示信息用于显性指示或隐性指示前一次第一业务数据传输中第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。其中,调度控制数据可以包括但不局限于物理下行控制信道(PDCCH)。需要说明的是,后一种情况下,两次第一业务数据传输的时间间隔小于非自容HARQ反馈方式的传输时延,否则,在后一次第一业务数据传输的调度控制数据来之前就要向基站发送HARQ反馈信息,即UE未接收到指示信息就需要向基站发送HARQ反馈信息。
保留生成模块72被配置为根据接收模块71接收的第一业务数据传输的调度控制数据中携带的指示信息,将抢占传输资源的第二业务数据保留在缓存中,并生成第一业务数据的HARQ反馈信息。
在一实施例中,当指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源时,保留生成模块72可以被配置为:将所有传输失败的数据均保留在缓存中,从 保留的数据中识别出传输失败的第一业务数据,并根据传输失败的第一业务数据生成HARQ反馈信息。
发送模块73被配置为向基站发送保留生成模块72生成的HARQ反馈信息。
当指示信息携带在后一次第一业务数据传输的调度控制数据中时,发送模块73可以被配置为以非自容HARQ反馈方式向基站发送HARQ反馈信息。
上述实施例,通过根据接收的第一业务数据传输中携带的指示信息,将抢占传输资源的第二业务数据保留在缓存中,使得第一业务数据传输过程中不会丢弃有用的第二业务数据。
图8是根据一示例性实施例示出的另一种HARQ反馈装置的框图,如图8所示,在上述图7所示实施例的基础上,保留生成模块72可以包括:第一生成子模块721或者第二生成子模块722。
第一生成子模块721被配置为根据除抢占传输资源的第二业务数据之外的数据传输成败状态生成HARQ反馈信息。
第二生成子模块722被配置为将抢占传输资源的第二业务数据的传输成败状态设置为传输成功,并根据第一业务数据传输中所有数据的传输成败状态生成HARQ反馈信息。
其中,可以通过多种方式生成第一业务数据的HARQ反馈信息,例如,可以根据除抢占传输资源的第二业务数据之外的数据传输成败状态生成第一业务数据的HARQ反馈信息,又例如,可以将抢占传输资源的第二业务数据的传输成败状态设置为传输成功,并根据第一业务数据传输中所有数据的传输成败状态生成HARQ反馈信息。
上述实施例,通过第一生成子模块或第二生成子模块生成的HARQ反馈信息可以正确地反映第一业务数据的传输成败状态,从而可以避免UE错误的操作。
图9是根据一示例性实施例示出的一种发送指示信息的装置的框图,该发送指示信息的装置位于基站中,该发送指示信息的装置包括:判断模块91和确定发送模块92。
判断模块91被配置为判断是否存在第二业务数据抢占第一业务数据的传输资源。
其中,第一业务可以包括但不局限于eMBB,第二业务可以包括但不局限于URLLC。由于第二业务相对于第一业务对及时性要求更高,因此,第二业务数据可以抢占第一业务数据。在该实施例中,基站可以判断是否存在第二业务数据抢占第一业务数据的传输资源。
确定发送模块92被配置为若判断模块91的判断结果是存在第二业务数据抢占第一业务数据的传输资源,则向UE发送第一业务数据传输,第一业务数据传输的调度控制数据中 携带指示信息,指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置,以用于UE根据指示信息将抢占传输资源的第二业务数据保留在缓存中,并向基站发送第一业务数据的HARQ反馈信息。
在该实施例中,若基站确定存在第二业务数据抢占第一业务数据的传输资源,则可以在向UE发送的第一业务数据传输的调度控制数据中携带指示信息,该指示信息可以显性地指示,例如可以直接增加若干比特(bit)的指示信息,也可以隐性地指示,例如,将指示信息以扰码的形式加扰到调度控制数据中的目标控制信息上,即对部分原有控制信息加扰携带相应的指示信息。该指示信息可以用于指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置,其中,可以采用位图(bitmap)的形式指示上述传输资源位置。UE在接收到该指示信息,可以根据指示信息将抢占传输资源的第二业务数据保留在缓存中,并向基站发送第一业务数据的HARQ反馈信息。
其中,基站向UE发送第一业务数据传输可以包括:基站向UE发送一次第一业务数据传输,这种情况下,指示信息可以携带在该次第一业务数据传输的调度控制数据中,该指示信息用于显性指示或隐性指示第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。
在一实施例中,确定发送模块92可以被配置为:向UE发送两次第一业务数据传输,两次第一业务数据传输的时间间隔小于非自容HARQ反馈方式的传输时延。其中,指示信息携带在后一次第一业务数据传输的调度控制数据中,指示信息用于显性指示或隐性指示前一次第一业务数据传输中第二业务数据抢占第一业务数据的传输资源或者第二业务数据抢占第一业务数据的传输资源位置。
上述实施例,通过在确定存在第二业务数据抢占第一业务数据的传输资源时,向UE发送携带指示信息的第一业务数据传输,以通知UE第二业务数据抢占第一业务数据的传输资源,从而使UE可以避免错误的操作。

当该指示信息指示第二业务数据抢占第一业务数据的传输资源位置时,基站可以接收UE发送的第一业务数据的HARQ反馈信息,该HARQ反馈信息包括与传输资源位置对应的第二业务数据的HARQ反馈信息和与其他传输资源位置对应的第一业务数据的HARQ反馈信息,并根据与其他传输资源位置对应的第一业务数据的HARQ反馈信息向UE重传传输失败的第一业务数据。也即基站在确定待重传的第一业务数据时,忽略与传输资源位置对应的第二业务数据的HARQ反馈信息,只考虑其他资源位置的第一业务数据的HARQ反馈信息。
上述实施例,通过根据接收的与其他传输资源位置对应的第一业务数据的HARQ反馈信息向UE重传传输失败的第一业务数据,使得基站可以识别出真正待重传的第一业务数据。
