Description

一种D2D数据包传输方法、传输资源分配方法及装置 技术领域
本发明涉及通信技术领域,具体涉及一种D2D数据包传输方法、传输资源分配方法及装置。
背景技术
第五代移动通信技术(5G)作为民用移动通信技术的下一个重要阶段,全球各个国家和技术组织已经展开了大量的研究;作为面向5G的关键候选技术,D2D(Device-to-Device,设备到设备通信)具有潜在的提高系统性能、提升用户体验、扩展蜂窝通信应用的前景,因此受到了广泛关注。
车联网是D2D的一个主要应用场景,在D2D的车联网应用场景中,车辆(V-UE)与路边单元(RSU)之间和V-UE间利用PC5接口进行通信,PC5接口是3GPP定义的近距离通信方法中D2D的标准接口;此外V-UE和RSU与LTE接入网(E-UTRAN)使用Uu口进行连接;利用D2D实现V2V(车辆之间通信)、V2I(车辆与路边单元等基础设施之间通信)传输数据时,D2D数据包传输的性能尤为重要;在传输D2D数据包时一个关键的问题为时延控制和数据传输的可靠性,时延控制和数据传输的可靠性在某种程度上会相互影响。
图1示出了目前D2D数据包重传方式的示意图,如图1所示,由于公共安全场景下的D2D技术,并未要求很高的可靠性和低时延,因此,目前协议定义多重传机制只要求发送端周期性的将D2D数据重复发送多次(如4次),通过接收端的重复接收技术,逐步提高数据包的成功解码概率;然而在车联网场景下,尤其是V2V场景下,时延控制的要求较高,目前在时域上重复发送数据,以实现D2D数据包传输的方式,必然带来较大的时延,无法满足车联网场景下的时延控制要求。
发明内容
有鉴于此,本发明实施例提供一种D2D数据包传输方法、传输资源分配 方法及装置,以达到通过较小的时延实现D2D数据包传输的目的。
为实现上述目的,本发明实施例提供如下技术方案:
一种D2D数据包传输方法,包括:
设置D2D数据包的多个数据包副本;
确定各数据包副本的传输频率,各数据包副本的传输频率不同;
将各数据包副本通过相应的传输频率进行传输。
本发明实施例还提供一种传输资源分配方法,包括:
判断D2D数据包是否对应有传输优先级;
若否,为所述D2D数据包分配普通频谱资源;
若是,为所述D2D数据包分配对应传输优先级的专用频谱资源。
本发明实施例还提供一种传输资源分配方法,包括:
判断D2D数据包的业务紧急等级;
若所述D2D数据包的业务紧急等级为紧急业务,确定基站RRC当前所指示的可用传输频率范围,从所述可用传输频率范围中选择D2D数据包的传输频率;
若所述D2D数据包的业务紧急等级为非紧急业务,从广播通信所指示的资源池中选择D2D数据包的传输频率。
本发明实施例还提供一种D2D数据包传输装置,包括:
副本设置模块,用于设置D2D数据包的多个数据包副本;
传输频率确定模块,用于确定各数据包副本的传输频率,各数据包副本的传输频率不同;
频域传输模块,用于将各数据包副本通过相应的传输频率进行传输。
本发明实施例还提供一种传输资源分配装置,包括:
业务判断模块,用于判断D2D数据包是否对应有传输优先级;
第一分配模块,用于若否,为所述D2D数据包分配普通频谱资源;
第二分配模块,用于若是,为所述D2D数据包分配对应传输优先级的专用频谱资源。
本发明实施例还提供一种传输资源分配装置,包括:
紧急等级判断模块,用于判断D2D数据包的业务紧急等级;
第一频率选择模块,用于若所述D2D数据包的业务紧急等级为紧急业务,确定基站RRC当前所指示的可用传输频率范围,从所述可用传输频率中选择D2D数据包的传输频率;
第二频率选择模块,用于若所述D2D数据包的业务紧急等级为非紧急业务,从广播通信所指示的资源池中选择D2D数据包的传输频率。
基于上述技术方案,本发明实施例提供的D2D数据包传输方法,包括:设置D2D数据包的多个数据包副本;确定各数据包副本的传输频率,各数据包副本的传输频率不同;将各数据包副本通过相应的传输频率进行传输。可以看出,本发明实施例可通过不同的传输频率传输D2D数据包的多个数据包副本,以实现D2D数据包的传输,由于避免了在时域上多周期的重传数据,而是通过不同的传输频率,调频的传输D2D数据包的多个数据包副本,因此本发明实施例提供的D2D数据包传输方法可实现较小的数据传输时延,达到较好的时延控制目的,同时,由于在频域上进行了调频处理,使得各数据包副本的传输频率不同,因此在传输D2D数据包时,也可获得一定的频率选择性增益。

可选的,信道当前通信质量可实时计算测得,误码率可根据历史数据统一得出;信道当前通信质量和误码率的测量方式有多种,本发明实施例不作限制。
值得注意的是,本发明实施例在频域上调频的传输D2D数据包的多个数据包副本,虽然减小了传输时延,但存在一个潜在问题,即由于数据发送需要占用多个频域资源,有可能导致系统频率资源的不足;
因此本发明实施例可预定义具有传输优先级的D2D数据包(如通过D2D数据包所属的业务类型,或者D2D数据包的具体发出方,接收方等定义D2D数据包的传输优先级),并设置传输优先级所对应的专用频谱资源,从而将具有传输优先级的D2D数据包,分配到为该传输优先级所分配的专用频谱资源中,确定传输频率;
具体的,本发明实施例在确定各数据包副本的传输频率时,可判断所述D2D数据包是否对应有传输优先级;若所述D2D数据包对应有传输优先级,则在为所述D2D数据包对应的传输优先级所分配的专用频谱资源中,确定各数据包副本的传输频率。
可选的,本发明实施例可根据实际需要设置哪个数据包具有传输优先级,且传输优先级对应的专用频谱资源。
可选的,本发明实施例可设置V2X数据包具有传输优先级,从而为V2X数据包分配专用频谱资源;
基于此,对于考虑到时延要求高的V2X(车量对外界的信息交换)业务发送的概率往往较低(如追尾、紧急制动在一个区域内属于小概率事件),因此时延要求高的V2X业务带来的频谱资源“浪费并不严重”;为了更好的解决此问题,本发明实施例考虑根据业务的不同QoS需求为V2X业务分配专用频谱资源;
如图10所示频谱资源分配示意图,普通D2D业务的数据包在传输时,在为普通D2D业务所分配的频谱资源上进行D2D数据包各数据包副本的传输频率选择,而不占用为V2X业务分配的专用频谱资源;V2X业务的数据包在传输 时,在为V2X业务所分配的专用频谱资源上进行D2D数据包各数据包副本的传输频率选择;
可选的,本发明实施例若确定所述D2D数据包为V2X数据包,则确定所述V2X数据包对应有传输优先级,进而在为V2X数据包所分配的专用频谱资源中,确定各数据包副本的传输频率;
具体的,发送端在确定需传输的D2D数据包后,可确定D2D数据包的业务类型,如果D2D数据包为V2X业务的数据包,则在确定各数据包副本的传输频率时,本发明实施例可在为V2X业务分配的专用频谱资源中,确定D2D数据包的各数据包副本的传输频率,且各数据包副本的传输频率不同。
可选的,对于普通D2D数据包中高优先级的D2D数据包,本发明实施例也可设置该高优先级的普通D2D数据包具有传输优先级,具有传输优先级的普通D2D数据包可根据实际需要设定;
具体的,在本发明实施例中,若所述D2D数据包为普通D2D数据包,且所述普通D2D数据包的传输优先级达到预定传输优先级,则确定所述普通D2D数据包对应有传输优先级;进而在为所述普通D2D数据包对应的传输优先级所分配的专用频谱资源中,确定各数据包副本的传输频率。
进一步,为D2D数据包对应的传输优先级分配专用频谱资源后,本发明实施例还可以实现不同业务的优先级处理从而更加合理的利用资源,避免多发紧急业务,和低发的非紧急业务之间的资源竞争;
具体的,为所述D2D数据包对应的传输优先级所分配的专用频谱资源可以进一步划分为:为紧急业务分配的频谱资源,和为非紧急业务分配的频谱资源;
本发明实施例可判断所述D2D数据包的业务紧急等级;若所述D2D数据包的业务紧急等级为紧急业务,则确定为所述D2D数据包对应的传输优先级所分配的专用频谱资源中的为紧急业务分配的频谱资源,在所确定的为紧急业务分配的频谱资源中,确定各数据包副本的传输频率;若所述D2D数据包的业务紧急等级为非紧急业务,则确定为所述D2D数据包对应的传输优先级所分配的专用频谱资源中的为非紧急业务分配的频谱资源,在所确定的为非紧急业务分配的频谱资源中,确定各数据包副本的传输频率;
具体的,在V2X场景下,图11示出了频谱资源分配的另一示意图,在为 V2X业务所分配的频谱资源中,还进一步划分了为V2X紧急业务所分配的频谱资源,和为V2X非紧急业务所分配的频谱资源,V2X紧急业务为追尾、紧急制动等需要快速处理的业务,紧急业务和非紧急业务可根据实际情况预先设定;
可以看出,在为V2X业务分配的专用频谱资源可以包括:为V2X紧急业务分配的频谱资源,和为V2X非紧急业务分配的频谱资源;具体的,在为V2X业务分配的专用频谱资源中,确定各数据包副本的传输频率时,本发明实施例可在确定所需传输的D2D数据包属于V2X业务后,判断D2D数据包的业务紧急等级,从而根据不同的业务紧急等级,在相应的频谱资源上确定各数据包副本的不同传输频率;
对应的,图12示出了本发明实施例提供的确定各数据包副本的传输频率的方法流程图,参照图12,该方法可以包括:
步骤S700、判断所述D2D数据包的业务紧急等级;
D2D数据包可以为V2X数据包。
步骤S710、若所述D2D数据包的业务紧急等级为紧急业务,则从所述专用频谱资源中为紧急业务分配的频谱资源中,确定各数据包副本的传输频率;
步骤S720、若所述D2D数据包的业务紧急等级为非紧急业务,则从所述专用频谱资源中为非紧急业务分配的频谱资源中,确定各数据包副本的传输频率。
本发明实施例中V2X业务由于使用了专用的频谱资源,因此,对于可靠性和时延要求很高的业务可以避免由于抢占不了资源带来的时延,也可以避免资源复用产生的干扰;而且由于采用了跳频的方式实现的多份数据发送,也一定程度上,降低了使用“唯一”资源时,资源复用带来的干扰对信号可靠性的影响;
可选的,在本发明实施例中,跳频的map(范围)可以是在基站RRC所指示的可用传输频率范围内,或广播通信所指示的资源池中随机选择,或也可以根据通信质量进行配置;如基站通过信道测量信息,可以获得V2X信道的通信质量,基站将该通信质量通知发送端,则发送端可根据此通信质量,选择通信较优的频率跳频map;
具体的,发送端可确定当前信道的通信质量;根据所述通信质量确定通信质量符合设定条件的频率范围,在所述频率范围中以跳频方式确定各数据 包副本的传输频率。
可选的,由于D2D数据包重传机制的变化,也会改变到调度信令的结构;因此,本发明实施例可以利用目前3GPP协议中的SA定义的bit map保留字节,实现根据当前信道的通信质量所进行的资源调度。
本发明实施例提供的D2D数据包传输方法可实现较小的数据传输时延,达到较好的时延控制目的,同时,由于是在频域上进行了调频处理,使得各数据包副本的传输频率不同,因此在传输D2D数据包时,也可获得一定的频率选择性增益。

步骤S810、为所述D2D数据包分配普通频谱资源;
D2D数据包不属于V2X业务,则认定D2D数据包为普通业务,如图10所示频谱资源分配示意图,普通D2D业务的数据包在传输时,在为普通D2D业务所分配的频谱资源上进行D2D数据包的频率分配,而不占用为V2X业务分配的专用频谱资源;V2X业务的数据包在传输时,在为V2X业务所分配的专用频谱资源上进行D2D数据包的频率分配;
可选的,在为所述D2D数据包分配普通频谱资源后,本发明实施例可在所述普通频谱资源中确定D2D数据包的多个不同传输频率,以使得D2D数据包 通过所述普通频谱资源中所确定多个不同传输频率进行传输;相应内容可参照上文描述。

可选的,对于普通D2D数据包中高优先级的D2D数据包,本发明实施例也可设置该高优先级的普通D2D数据包具有传输优先级,具有传输优先级的普通D2D数据包可根据实际需要设定;从而为高优先级的普通D2D数据包分配专用频谱资源;
具体的,若所述D2D数据包为普通D2D数据包,且所述普通D2D数据包的传输优先级达到预定传输优先级,则可确定所述普通D2D数据包对应有传输优先级,进而为所述普通D2D数据包分配对应传输优先级的专用频谱资源。
进一步,为D2D数据包划分的专用频谱资源中,还可以实现不同业务的优先级处理,从而更加合理的利用资源,避免多发业务的紧急业务,和低发的非紧急业务之间的资源竞争;
具体的,所述为所述D2D数据包分配的对应传输优先级的专用频谱资源可以包括:为紧急业务分配的频谱资源,和为非紧急业务分配的频谱资源;
进一步,本发明实施例可判断所述D2D数据包的业务紧急等级;若所述D2D数据包的业务紧急等级为紧急业务,则为所述D2D数据包分配对应传输优先级的专用频谱资源中的为紧急业务分配的频谱资源;若所述D2D数据包的业务紧急等级为非紧急业务,则为所述D2D数据包分配对应传输优先级的专用频谱资源中的为非紧急业务分配的频谱资源。
在V2X场景下,所述D2D数据包分配的专用频谱资源可以包括:为V2X紧急业务分配的频谱资源,和为V2X非紧急业务分配的频谱资源;如图11所示频谱资源分配的另一示意图,在为V2X业务所分配的频谱资源中,还进一 步划分了为V2X紧急业务所分配的频谱资源,和为V2X非紧急业务所分配的频谱资源,V2X紧急业务为追尾、紧急制动等需要快速处理的业务,紧急业务和非紧急业务可根据实际情况预先设定;
