相关申请的交叉引用
本申请基于申请号为201710193005.4、申请日为2017年03月28日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及通信领域,尤其涉及一种数据传输方法、装置、终端及存储介质。
背景技术
在相关技术中,随着经济社会高速发展,中国汽车保有量迅速增长,道路交通事故频繁发生,已成为近年来影响我国公众安全感的重要因素之一。提升车辆安全的技术主要分为被动安全技术和主动安全技术。被动安全技术配置为在事故发生后,对车内、车外人员及物品的保护;主动安全技术配置为防止和减少车辆发生事故,避免人员受到伤害。主动安全技术是现代车辆安全技术发展的重点和趋势。
车联网系统是指通过装载在车辆上的传感器、车载终端及电子标签等设备提供车辆信息,采用各种通信技术实现车与车V2V(Vehicle to Vehicle V2V)、车与人V2P(Vehicle to Person,V2P)、车与基础设施(Vehicle to Infrastructure,V2I)之间的互连互通,并在信息网络平台上对信息进行提取、共享等有效利用,对车辆进行有效的管控和提供综合服务的系统。车联网可以实现基于通信的车辆信息通知及碰撞危险预警,通过利用先进的无线通信技术和新一代信息处理技术,实现车与车、车与路侧基础设施间的实时信息交互,告知彼此目前的状态(包括车辆的位置、速度、加速度、 行驶路径)及获知的道路环境信息,协作感知道路危险状况,及时提供多种碰撞预警信息,防止道路交通安全事故的发生,成为当前解决道路交通安全问题的一种新的思路。
近年来随着新的移动通信技术的发展,基于长期演进系统(Long Term Evolution,LTE)技术来解决车联网通信是热点研究之一。其中,在LTE系统的设备到设备(Device to Device,D2D)通信方式中,用户设备(User Equipment,UE)之间有业务需要传输时,UE之间的业务数据不经过基站的转发,而是直接由数据源UE通过空中接口传输给目标UE,图1是根据相关技术中的D2D通信结构的示意图,如图1所示,包括基站1,终端UE1,终端UE2,这种通信模式具有明显区别于传统蜂窝系统通信模式的特征,对于车联网的V2V通信来说,车与车之间的近距离通信可以应用D2D通信方式,达到节省了无线频谱资源,降低了核心网的数据传输压力,能够减少系统资源占用,增加蜂窝通信系统频谱效率,降低终端发射功耗,并在很大程度上节省网络运营成本等效果。

下面结合本公开实施例进行详细说明。
相关技术中定义的R14V2V通信采用了广播方式,发送端最多可以在两个载波上发送相应的业务信息,这些设置通常用来实现车辆之间或者车辆与其他设备之间的基本安全业务的传输,但是上述相关技术中的技术方案,对于新的V2X业务例如车辆间道路环境感知数据传输,无人驾驶数据传输等,从数据速率或者是时延上将不能很好的满足上述V2X的通信需求,因此从UE能力上进行增强,sidelink多载波数据传输技术可以较好的解决上述问题,图4是根据相关技术中的UE在sidelink上多载波数据传输的示意图,如图4所示,TX UE表示发送端UE,RX UE表示接收端UE。
在相关技术已经解决了在基站的配置下或者UE的预配置下,UE可以在sidelink链路上选择物理sidelink控制信道(Physical Sidelink Control Channel,PSCCH)和PSSCH资源进行数据发送,但是对于更大的数据业务,往往需要更大的带宽支持,在sidelink链路上可能无法找到合适的连续的大带宽进行数据发送,因此发送端可能需要聚合多个载波同时进行数据的发送,以满足新业务的大数据量以及低时延的要求。当发送端需要在多个载波上进行数据发送时,就需要发送与各个载波相应的调度信息和数据信息。目前的协议确定了发送UE只支持sidelink链路上单载波数据的调度发送,对于跨载波调度却不支持。
本公开实施例中的技术方案的目的是解决上述相关技术中存在的问题。为使本公开实施例的目的、技术方案和优点更加清楚明白,下文中将结合附图对本公开的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。

表示子载波数目为12个或24个。
基于LTE的D2D通信系统中,使用系统上行子帧作为物理边链路共享 信道(Physical Sidelink Shared Channel,PSSCH)子帧,配置为传输D2D数据。D2D发送端在边链路(即D2D链路)控制信息(Sidelink Control Information,SCI)中指示所使用的PSSCH资源。V2V系统作为一种D2D通信方式的特殊应用,可以使用D2D通信方案,即采用SCI信息指示相应的数据信道资源配置,并在相应的数据信道资源上传输V2V数据信息。
目前协议已经确定了V2V在sidelink链路上通过车载感知设备sensing,选择合适的时频资源发送数据信息。发送端最多可以使用2个载波,这些设置基本可以满足传统的基本安全业务的传输,但是对于某些场景下的新的V2X业务,可能需要更大的数据速率,更低的时延才能够保证数据信息有效的传输。从UE能力上来说会有一定的增强。其中载波聚合技术就是一个解决问题的技术。
当发送UE在多个载波上进行数据发送时,接收端不得不盲检控制信息,然后根据控制信息再去解调接收控制信息指示的数据信息。为了减小接收UE的盲检复杂度,在本公开实施例可以将所有载波上发送的数据信息对应的控制信息在同一个sidelink链路的载波上发送。
相关技术中的当前协议规定的V2X在sidelink上的控制信息SCI的内容为:
Priority-3 bits as defined in section 4.4.5.1 of[7]
-Resource reservation–4 bits as defined in section 14.2.1 of[3]
-Frequency resource location–
Figure PCTCN2018078419-appb-000004
bits as defined in section 14.1.1.4C of[3].
-Time gap between initial transmission and retransmission-4 bits as defined in section 14.1.1.4C of[3]
-Modulation and coding scheme–5 bits as defined in section 14.2.1 of[3]
-Retransmission index–1 bit as defined in section 14.2.1 of[3].
-Reserved information bits are added until the size of SCI format 1 is equal to 32 bits.The reserved bits are set to zero.
从上述V2X的SCI内容中没有与载波相关的信息,该SCI只能够指示当前载波的数据资源信息,即发送端只支持单载波数据发送,并不具备跨载波调度的能力。
为了实现sidelink链路的载波聚合发送,当选择跨载波调度时,就需要在控制信息增加载波指示信息。在本实施例中将发送控制信息的载波可以认为是发送端的第一载波,将只有数据发送的载波认为是发送端的第二载波,此外,由于接收端在第二载波上接收数据时没有了该载波上的资源池信息,因此,第一载波上的控制信息不仅要能指示出发送数据的第二载波的信息,还要能够指示第二载波上发送资源池信息。
为了达到上述载波指示的目的,本实施例可以对UE的所有可以使用的载波进行编号索引,同样也可以对各个载波上的发送资源池进行编号索引。在控制指示信息中对使用在载波以及载波上的发送资源池指示,该指示信息可以是显示的指示,也可以是隐式的一种对应关系映射指示,这样接收端通过指示信息能够进行有效的数据接收。
另外,由于发送端在多个载波上进行数据发送,接收端需要识别出来哪些数据是由哪些发送端发送的,这样接收端才能够在物理层或者高层进行数据的选择,合并等处理,因此,需要标记出哪些数据是哪个发送端发送的。同样的,发送端可以在控制信息中继续增加指示信息配置为接收端的数据识别。
以下是本公开实施例的实施方法,每个实施方法包括多个实例。
实施方法一:在控制信息中增加指示位,显式(直接)指示载波和资源池信息
实施方法一的实例1:
发送端在某第二载波上发送数据,则UE在第一载波上选择PSCCH资源发送对应第二载波上数据的控制信息SCI,假设UE可用的所有载波编号为载波1,载波2,……,载波k,则对这k个载波进行编号,对log2(k)向上取整为k’,那么就可以使用k’bit信息来对应指示这k个载波;
同样的,假设在某载波上的发送资源池为资源池1,资源池2,……,资源池n,对这n个资源池也进行编号,对log2(n)向上取整为n’,那么就可以使用n’bit信息来对应指示这n个资源池;
然后,与R14定义的V2V sidelink控制信息相比,控制信息中需要增加(k’+n’)bit的信息来进行载波指示和资源池指示。
实施方法一的实例2:
类似于实例1,发送端在某第二载波上发送数据,则UE在第一载波上选择PSCCH资源发送对应第二载波上数据的控制信息SCI,假设UE可用的所有载波编号为载波1,载波2,……,载波k,则对这k(k>=m)个进行编号,对log2(k)向上取整为k’,那么就可以使用k’bit信息来对应指示这k个载波;
但是对于同一个发送UE,假定其在第二载波上使用的资源池与第一载波上使用的是相同的资源池,那么与实例1相比可以节省n’bit的开销,
与R14定义的V2V sidelink控制信息相比,控制信息中需要增加k’bit的信息来进行载波指示和资源池指示。
实施方法一的实例3:
发送端在某个第二载波上发送数据,则UE在第一载波上选择PSCCH资源发送对应第二载波上数据的控制信息SCI,假设UE可用的所有载波数目为k个。
第一个载波上的发送资源池数据为n1,第二个载波上的资源池数目 n2,……,第k个载波上的发送资源池数目为nk,那么所有的载波上的发送资源池一共有N=(n1+n2+……+nk)个,对这N个发送资源池进行编号索引,对log2(N)向上取整为N’,那么就可以使用这N’bit的信息来位置得指示出使用哪个载波上的哪个发送资源池。
然后,与R14定义的V2V sidelink控制信息相比,各个控制信息中需要增加N’bit的信息来进行载波指示和资源池指示。
实施方法一的实例4:
发送端根据基站信令或者预配置信息选择第一载波和第二载波,则发送UE在第一载波上选择PSCCH资源发送控制指示信息,其中该控制指示信息包含了所有的载波上的数据资源指示信息。
类似于实例1,首先对UE可用的所有k个载波进行编号,并对编号后的载波进行排序分类,例如0号代表第一载波,1号代表第二载波中的载波1,2号代表第二载波中的载波2等等。
再次,如果默认的载波聚合的时候有一定的顺序,例如载波0和载波2一起使用的时候,认为指示的载波顺序按照载波的编号由小到大,那么UE使用的所有载波的可能种类为
Figure PCTCN2018078419-appb-000005
个;
如果认为载波聚合的时候载波的指示没有一个顺序,那么UE使用的所有载波的可能种类为
Figure PCTCN2018078419-appb-000006
个;
然后可以对这J个情况进行编号索引,使用log2(J)向上取整为J’,那么可以使用J’bit的信息对载波的使用情况进行一一对应;
然后,对排序后的所有的载波上的所有发送资源池进行编号索引,假设所有载波上的所有资源池一共有n个,那么同样使用log2(n)向上取整为n’,使用这n’bit的信息可以指示出发送UE在各个载波上使用的资源池。
然后,与R14定义的V2V sidelink控制信息相比,需要增加(J’+K*n’)bit的信息来进行载波指示和资源池指示。
实施方法一的实例5
发送端根据基站信令或者预配置信息选择第一载波和第二载波,图6是根据本公开实例5的跨载波调度通信在第一载波上只发送一个集中调度控制信息的示意图,如图6所示,data0、data1等表示各个数据,发送UE在第一载波上选择PSCCH资源发送一个集中的控制指示信息SCI,其中该控制指示信息包含了所有使用的载波上的独立调度数据资源控制指示信息SCI。其中,独立调度指示信息SCI中包含了载波指示信息和资源池指示信息。然后集中控制指示SCI中的独立控制指示SCI对应的载波位置上发送相应的数据。图7是根据本公开实例5的集中调度边链路控制指示信息SCI的结构示意图。
图8是根据本公开实例5的跨载波调度通信时在第一载波上发送多个独立控制信息的示意图,如图8所示,发送端在第一载波发送多个控制指示信息SCI,每个SCI中包含了一个载波的载波指示信息或者资源池指示信息。
实施方法一的实例6:
发送端根据基站信令或者预配置信息选择第一载波和第二载波,则发送UE在第一载波上选择1个资源位置发送控制指示信息,其中该控制指示信息包含了所有的载波上的数据资源指示信息。类似与实例4,如果假设各个载波上的发送资源池配置默认是一样的,那么与实例4相比我们减少配置为指示各个载波上资源池信息的n’bit信息。
与R14定义的V2V sidelink控制信息相比,各个控制信息中需要增加J’bit的信息来进行载波指示和资源池指示。
实施方法一的实例7
发送端在多个载波上发送消息时,由于目前的控制信息SCI中并未有关于source的相关信息指示,因此为了接收端能够有效的识别出多个载波上来自于用一个发送端的消息,可以在第一载波上的SCI中增加与发送源有关的指示信息,这样接收UE就可以通过SCI中的source信息判断是否接收这些包等操作。
实施方法二:第一载波上PSCCH资源与对应指示的载波和/或资源池隐式对应
实施方法二的实例8
发送端在某个载波上发送数据,则UE在第一载波上选择PSCCH资源发送对应第二载波上数据的控制信息SCI,假设UE可用的所有载波编号为载波1,载波2,……,载波k共k个载波,将第一载波上的PSCCH按照一定的对应关系对应到各载波位置上,例如有m个PSCCH资源(m大于或者等于k),那么PSCCH资源与载波位置的对应关系可以设置为mod(k,m)值为对应的子载波位置。当在第一载波上发送第i个载波上的SCI时,寻找满足mod(k,m)=i对应的PSCCH位置并进行发送。
其次,假设在某载波上的发送资源池为资源池1,资源池2,……,资源池n,对这n个资源池也进行编号,对log2(n)向上取整为n’,那么就可以使用n’bit信息来对应指示这n个资源池;
然后,与R14定义的V2V sidelink控制信息相比,控制信息中需要增加n’bit的资源池指示信息来进行载波间接指示和资源池直接指示。
实施方法二的实例9
发送端在某个载波上发送数据,则UE在第一载波上选择PSCCH资源发送对应第二载波上数据的控制信息SCI,假设UE可用的所有载波假设UE可用的所有载波为载波1,载波2,……,载波k,则对这k个载波进行编号,对log2(k)向上取整为k’,那么就可以使用k’bit信息来对应指示这k个载波;
其次,UE在第一载波上选择PSCCH资源发送对应第二载波上数据的控制信息SCI,假设在某载波上的发送资源池编号为资源池1,资源池2,……,资源池n,共n个资源池,那么可以将第一载波上PSCCH的资源位置与n个资源池对应起来,例如有m个PSCCH资源(m>=n),那么PSCCH资源与载波位置的对应关系可以设置为mod(n,m)值为对应的资源池。当发送某第二载波控制信息SCI且该第二载波使用资源池i时,寻找满足mod(n,m)=i对应的PSCCH位置并进行发送;
然后,与R14定义的V2V sidelink控制信息相比,控制信息中需要增加k’bit的资源池指示信息来进行载波直接指示和资源池间接指示。
