Description

业务传输与业务配置的发送方法及装置、存储介质、终端、基站
本申请要求于2019年3月22日提交中国专利局、申请号为201910223926.X、发明名称为“业务传输与业务配置的发送方法及装置、存储介质、终端、基站”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
本发明涉及无线通信技术领域,具体地涉及一种业务传输与业务配置的发送方法及装置、存储介质、终端、基站。
背景技术
车与外界的信息交换(Vehicle to X,简称V2X,也可称为vehicle to everything)是未来智能交通运输系统的关键技术,主要研究基于第三代合作伙伴项目(the 3rd Generation Partnership Project,简称3GPP)通信协议的车辆数据传输方案。V2X通信包括车与车(Vehicle to Vehicle,简称V2V)通信、车与路侧基础设施(Vehicle to Infrastructure,简称V2I)通信以及车与行人(Vehicle to Pedestrian,简称V2P)通信。V2X应用将改善驾驶安全性、减少拥堵和车辆能耗、提高交通效率和车载娱乐信息等。
在长期演进(Long Term Evolution,简称LTE)通信系统中,V2X通信是以广播通信为基础的,采用的是“一对所有”的通信模式。在这种通信模式下,接收终端不需要向发送终端反馈数据是否接收成功。如果一次传输不足以满足业务的可靠性需求,所述发送终端可以在没有反馈信息的情况下,按照预设次数重传数据包。
第五代移动通信技术(5th-Generation,简称5G)新无线(New  Radio,简称NR,也称为新空口)通信系统中,引入了单播的V2X通信,采用“一对一”的通信模式。这种情况下,利用混合自动重传请求(HybridAutomatic Repeat reQuest,简称HARQ)确认/否定确认(ACKnowledgement/Non-ACKnowledgement,简称ACK/NACK)机制,所述接收终端可以向所述发送终端反馈数据是否接收成功。其中,确认(ACK)表示接收成功,否定确认(NACK)表示没有接收成功,如果没有接收成功,则所述发送终端可以进行重传。和没有反馈信息的重传相比,有反馈信息的重传提高了资源利用率。
虽然重传可以提高数据传输的成功概率,提高V2X业务的可靠性,但是,并非所有V2X业务都需要重传。不同V2X业务有不同的可靠性需求。也就是说,V2X中存在高可靠性需求的业务和低可靠性需求的业务。对某些V2X业务来说,是不需要重传的,一次传输即可满足业务的可靠性需求;对其他业务来说,可能需要一次重传、两次重传,甚至三次重传、四次重传。
当所述发送终端发送的仅仅是低可靠性需求的业务时,重传是冗余的,会导致资源利用率的下降,因而需要避免冗余重传。

具体实施方式
如背景技术所言,当传输的V2X业务是低可靠性需求的业务时,重传可能是冗余的,将导致资源利用率的下降。
具体而言,数据要传输,无论初传还是重传,首要获取传输资源。NRV2X中,存在两种传输资源的获取方式:模式1和模式2。在模式1中,发送终端从基站获得传输资源,之后利用获得的传输资源向接收终端发送数据。在模式2中,所述发送终端通过感知或探测(sensing)的方式,从一组资源中选择出满足需求的资源用于数据传输。所述资源可以是没有被其他的用户终端(User Equipment,简称UE)占用的资源,或者,所述资源是被其他的UE占用,但干扰强度不大的资源。
所述发送终端可以只获取本次传输的资源,也可以一次性获取初传以及后续所有重传需要的资源。
当所述发送终端基于获取的资源向所述接收终端发送数据时,除了发送数据本身,还需要发送直连链路控制信息(Sidelink control information,简称SCI)。SCI可以携带与调度相关的控制信息,用于 指示所述接收终端正确接收数据。
之后,如果所述接收终端需要进行反馈,那么反馈信息同样需要无线资源承载。对于模式1,用于反馈的资源通常也是基站提供的,而对于模式2,用于反馈的资源通常也是由所述发送终端从一组资源中选择而来。
当采用模式1时,所述发送终端发送的数据可能是可靠性要求比较低的数据,如果所述接收终端没有成功接收数据,那么所述接收终端可以向所述发送终端或者向基站反馈。此时,由于基站不知道数据的可靠性需求,因而基站可能会要求所述发送终端进行数据重传,这将导致资源的浪费,降低资源利用率。
为解决上述技术问题,本发明实施例提供一种业务传输方法,包括:接收业务配置信息,所述业务配置信息包括业务与数据传输次数的对应关系,或者所述业务与数据重传次数的对应关系;根据所述业务配置信息,传输待传输业务数据包。本发明实施例中,在获得基站配置的业务配置信息之后,发送终端可以得知各个业务与数据传输/数据重传次数的对应关系,并根据该对应关系和所述待传输业务数据包的可靠性需求进行数据传输,从而有效避免冗余重传,提高资源利用率。
本发明实施例还提供一种信令发送方法,包括:根据待传输业务数据包包含的各个业务的可靠性需求,确定所述待传输业务数据包的可靠性需求;发送所述待传输业务数据包的可靠性需求。本发明实施例利用终端已知每个待传输业务数据包的可靠性需求,从而可以由所述终端将所述可靠性需求,发送出去,从而可以通知基站所述待传输业务数据包的可靠性需求,进而由基站根据所述可靠性需求确定是否调度重传资源,为避免冗余重传提供可行方案,有利于提高资源利用率。
为使本发明的上述目的、特征和有益效果能够更为明显易懂,下面结合附图对本发明的具体实施例做详细的说明。

图1是本发明实施例的一种业务传输方法的流程示意图。所述业务传输方法可以由终端执行,例如由NR V2X UE执行。具体而言,所述业务传输方法可以包括以下步骤:
步骤S101,接收业务配置信息,所述业务配置信息包括业务与数据传输次数的对应关系,或者所述业务与数据重传次数的对应关系;
步骤S102,根据所述业务配置信息,传输待传输业务数据包。
更具体而言,基站(例如,NR gNB)可以配置业务配置信息,所述业务配置信息可以包括业务与数据传输次数的对应关系。或者,业务配置信息可以包括所述业务与数据重传次数的对应关系。
之后,所述基站可以将所述业务配置信息发送至第一终端,例如,所述第一终端为发送终端。
需要说明的是,所述业务可以用逻辑信道(LogicalChannel,简称LCH)、逻辑信道组(LogicalChannel Group,简称LCG)、目标(Destination)、目标索引(Destination index)、服务质量(Quality of Service,简称QoS)参数中至少之一来表征,本发明对此不作限定。
具体而言,当业务由逻辑信道表征时,所述业务配置信息包括逻辑信道与数据传输次数的对应关系,或者,所述业务配置信息包括逻辑信道与数据重传次数的对应关系;当业务由具体的QoS参数表征时,所述业务配置信息包括QoS参数与数据传输次数的对应关系,或者,所述业务配置信息包括QoS参数与数据重传次数的对应关系;当业务由逻辑信道和目标表征时,所述业务配置信息包括逻辑信道和目标与数据传输次数的对应关系,或者,所述业务配置信息包括逻辑信道和目标与数据重传次数的对应关系。
具体而言,所述服务质量参数包括以下参数至少之一:优先级(priority),时延(delaybudget),可靠性(reliability),误包率(error rate),数据速率(datarate)。
在步骤S101中,所述第一终端可以从所述基站接收到所述业务配置信息,从而得知所述业务与数据传输次数的对应关系,或者所述业务与数据重传次数的对应关系。
在步骤S102中,所述第一终端可以根据所述业务配置信息,向第二终端(例如,所述第二终端为接收终端)传输待传输业务数据包。
作为一个非限制性的例子,所述基站通过所述业务配置信息配置了业务和传输次数的对应关系。例如,所述基站通过所述业务配置信息配置第一业务的传输次数为1时,表示所述第一业务的数据只需要传输一次。
作为又一个非限制性的例子,所述基站通过所述业务配置信息配 置了业务和重传次数的对应关系。例如,所述第一业务的重传次数为1,表示所述第一业务的数据可以重传一次(即,所述第一业务一共可以传输两次)。
进一步,所述第一终端可以维护计数器,利用所述计数器记录所述待传输业务数据包的传输次数。
所述待传输业务数据包,可以包含一个或多个业务,所述一个或多个业务可以对应相同或不同的数据传输次数或数据重传次数。
在具体实施中,当第一次传输所述待传输业务数据包时,可以初始化计数器的计数值为0,如果所述待传输业务数据包进行一次重传,则将所述计数器的计数值加1。所述计数器的最大计数值可以等于(N-1)。N表示所述待传输业务数据包的传输次数,N由所述待传输业务数据包所包含的业务对应的数据传输次数确定,且N为正整数。在这种计数方式下,计数值等于N为预设条件。
作为一个变化例,N=N1,N1表示所述待传输业务数据包所包含的业务中,数据传输次数最大的业务的数据传输次数。
作为一个变化例,当第一次传输所述待传输业务数据包时,可以初始化计数器的计数值为0,如果所述待传输业务数据包进行一次重传,则将所述计数器的计数值加1。所述计数器的最大计数值等于M。其中,M表示所述待传输业务数据包的重传次数,M由所述待传输业务数据包所包含的业务对应的数据重传次数确定,且M为正整数。在这种计数方式下,计数值等于M为预设条件。

作为又一个变化例,当第一次传输所述待传输业务数据包时,可以初始化计数器的计数值为N,N表示所述待传输业务数据包的传输次数,N由所述待传输业务数据包所包含的业务对应的数据传输次数确定,且N为正整数。如果所述待传输业务数据包进行一次重传, 则将所述计数器的计数值减1,直至所述计数器的计数值减小至1。在这种计数方式下,N减小至1为预设条件。
作为再一个变化例,当第一次传输所述待传输业务数据包时,可以初始化计数器的计数值为M,如果所述待传输业务数据包进行一次重传,则将所述计数器的计数值减1,直至所述计数器的计数值减小至0。其中,M表示所述待传输业务数据包的重传次数,M由所述待传输业务数据包所包含的业务对应的数据重传次数确定,且M为正整数。在这种计数方式下,M减小至0为预设条件。
进一步,当HARQ消息由第二终端发送至所述基站且所述计数器的计数值满足预设条件时,所述第一终端可以指示所述第二终端向所述基站发送ACK。需要说明的是,无论所述第二终端是否成功接收所述待传输业务数据包,在所述计数器的计数值达到预设条件时,所述第二终端都向所述基站反馈ACK。
作为一个变化实施例,当HARQ消息由所述第一终端转发至所述基站且所述计数器的计数值达到预设条件时,无论所述第二终端反馈给所述第一终端的HARQ消息是ACK还是NACK,所述第一终端都产生ACK,并发送ACK至所述基站。
作为一个变化实施例,当所述计数器的计数值满足预设条件时,所述第一终端清空所述待传输业务数据包对应的HARQ进程占用的HARQ缓存。
作为一个变化实施例,当所述计数器的计数值满足预设条件时,当所述第一终端确认传输资源为所述待传输业务数据包对应的HARQ进程的重传资源时,则所述第一终端释放所述传输资源。
作为一个变化实施例,当所述计数器的计数值满足预设条件时,在向所述第二终端发送直连链路控制信息(Sidelink Control Information,简称SCI)之前,可以将所述直连链路控制信息中的初传和重传的时间间隔域(Time gap between initial transmission and  retransmission)设置为0,或者设置为距离下一次新传资源的时间间隔。
需要说明的是,所述初传和重传的时间间隔域也可以是其他用于表征本次传输资源和下一次传输资源的时间间隔的域,优选的,所述本次传输资源和下一次传输资源可以是属于同一HARQ进程的传输资源,本发明实施例对此不做限定。

由上,通过本发明实施例提供的技术方案,进行V2X通信时,可以有效避免多余重传,提高资源利用率。
图5是本发明实施例的一种信令发送方法的流程示意图。所述信令发送方法可以由终端执行,例如由NRV2X UE执行。具体而言,所述信令发送方法可以包括以下步骤:
步骤S501,根据待传输业务数据包包含的各个业务的可靠性需求,确定所述待传输业务数据包的可靠性需求;
步骤S502,发送所述待传输业务数据包的可靠性需求。
更具体而言,在步骤S501中,由于发送终端是知道待传输业务 数据包内包含哪些业务以及各个业务对应的可靠性需求的,因而所述发送终端可以根据待传输业务数据包内包含的各个业务的可靠性需求,确定待发送传输数据包的可靠性需求。
作为一个实施例,所述待传输业务数据包的可靠性需求为所述待传输业务数据包内所包含的所有业务的最高可靠性需求,也即,所述待传输业务数据包的可靠性需求为所述待传输业务数据包内所包含的所有业务的可靠性需求最高的业务的可靠性需求。
在步骤S502中,所述发送终端可以发出所述待传输业务数据包的可靠性需求。
在具体实施中,如果接收终端直接向所述基站上报HARQ消息,则所述发送终端可以基于SCI发送所述待传输业务数据包的可靠性需求至所述接收终端。

在具体实施中,如果所述接收终端无法直接向所述基站上报HARQ消息,则所述发送终端可以将所述待传输业务数据包的可靠性需求发送至所述基站。具体而言,在确定所述待传输业务数据包的可靠性需求并接收到所述接收终端发送的HARQ反馈消息之后,所述发送终端可以向所述基站转发所述HARQ反馈消息时,一并将所述待传输业务数据包的可靠性需求发送至所述基站,以使得所述基站根据所述待传输业务数据包的可靠性需求确定是否为所述待传输业务数据包调度重传资源。
作为一个变化例,在具体实施中,如果所述接收终端无法直接向所述基站上报HARQ消息,则所述发送终端可以首先确定所述待传 输业务数据包关联的业务标识,之后将所述待传输业务数据包的业务标识发送至所述基站。
具体而言,在确定所述待传输业务数据包关联的业务标识并接收到所述接收终端发送的HARQ反馈消息之后,所述发送终端可以向所述基站转发所述HARQ反馈消息,且一并将所述待传输业务数据包的业务标识发送至所述基站,以使得所述基站根据所述待传输业务数据包的业务标识确定是否为所述待传输业务数据包调度重传资源。

在步骤S602中,所述接收终端可以向所述基站发送HARQ反馈消息,且一并携带所述待传输业务数据包的可靠性需求。
或者,所述接收终端可以向所述基站发送HARQ反馈消息时,可以一并发送所述待传输业务数据包的业务标识,以使所述基站确定所述待传输业务数据包的可靠性需求,进而使所述基站确定是否为所述待传输业务数据包调度重传资源。
在具体实施中,所述接收终端可以根据预配置的HARQ反馈资源与可靠性需求之间的映射关系,确定所述HARQ反馈消息采用的HARQ反馈资源。之后,所述接收终端可以采用确定的HARQ反馈资源,向所述基站发送所述HARQ反馈消息。之后,所述基站可以根据预配置的HARQ反馈资源与可靠性需求之间的映射关系,确定是否为所述待传输业务数据包调度重传资源。
