Description

一种数据反馈资源的确定方法及装置
本申请要求于2017年3月20日提交中国专利局、申请号为201710166177.2、申请名称为“一种数据反馈资源的确定方法及装置”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
本申请涉及无线通信技术领域,尤其涉及一种数据反馈资源的确定方法及装置。
背景技术
车联网系统旨在通过车辆与其他设备(Vehicle to Everything,V2X)之间的通信来达到提高道路安全,提高交通效率和为用户提供丰富的流媒体服务的目的,其中所述其他设备包括车辆,手持终端,路边单元(RSU,Road Side Unit),以及网络等,所述车辆与其他设备之间的通信包括车辆与车辆(Vehicle to Vehicle,V2V),车辆与行人(Vehicle to Pedestrian,V2P),车辆与网络(Vehicle to Network,V2N)等,V2V、V2P、V2I统称为V2X。
目前蜂窝通信采用2G/3G/4G等技术,在4G系统中采用的长期演进(Long Term Evolution,LTE)技术具有高速率,低延迟,大覆盖范围,以及支持高速移动终端等优点,因此,在蜂窝网络中进行辆与外界信息之间的通信,可以充分利用中央调度器,如基站(eNB)来进行传输资源的动态调度,从而降低通信冲突的概率,并且解决不可控的时延问题。LTE-V2X技术是基于LTE蜂窝网络的车辆与其他设备进行信息交互的技术,是现有蜂窝网络技术的延伸。
在LTE-V2X系统中,车辆与其他设备之间的通信,通常有两种方式。第一种方式中,车辆采用广播的方式向周围的其他车辆或节点发送自身的状态信息,不需要基站进行数据的转发,如图1A所示;第二种方式中,车辆首先将自身的状态信息发送给基站,基站再通过单播或者广播的方式将接收到的数据发送给其他车辆或节点,如图1B所示。
然而,现有车联网技术领域中,作为发送端的车辆只能确定需要发送的数据是否完成发送,由于没有定义数据的反馈资源,因此,作为发送端的车辆无法确定发送的数据是否被成功接收,数据传输的可靠性低。

具体实施方式
本申请实施例可以应用于但不限于端到端(Device to Device,D2D)和V2X通信中,本申请实施例中的终端也可称之为用户设备(User Equipment,UE)、移动台(Mobile Station,MS)、移动终端(Mobile Terminal)等,可选的,该终端可以为车辆、手机、平板电脑、个人数字助理(Personal Digital Assistant,PDA)、销售终端(Point of Sales,POS)、车载电脑、机顶盒等。
本申请实施例中,V2X通信可以包括但不限于:车辆与车辆(Vehicle to Vehicle,V2V)通信、车辆与基础设施(Vehicle-to-Infrastructure,V2I)通信,以及车辆与行人(Vehicle-to-Pedestrian,V2P)通信,车辆与网络(Vehicle-to-Network,V2N)之间的通信等等;其中,V2I通信中可以包括但不限于车辆与基站通信、车辆与路边单元通信以及车辆与交通灯上的通信模块通信等。
在V2X系统中,车辆与其他节点之间的通信,通常有两种方式。第一种,车辆采用广播的方式向周围的其他车辆发送自身的状态信息,此时,不需要基站进行数据的转发,这种通信方式和D2D系统类似,如图1A所示;第二种,车辆的数据通过基站转发,此时,车辆首先将数据发送给基站,基站再通过单播或者广播的方式将接收到的数据发送给其他车辆或者节点。如图1B所示。
在图1A中,终端采用D2D广播的方式发送数据,可以采用模式1或者模式2的方式进行数据的发送,在模式1中,基站为终端分配确定的传输资源;在模式2中,终端在基 站配置的资源池,或者预配置的资源池中自主选取资源进行数据的传输。
D2D通信是两个终端之间数据的直接传输,采用调度分配(Scheduling Assignment,SA)部分+数据(Data)部分的机制;SA,通常又称为侧行链路控制信息(Sidelink control information,SCI),是用来指示从发端发出的数据的控制信息,例如数据的时频资源信息,调制编码方案(Modulation and Coding Scheme,MCS)信息,跳频指示,定时提前信息,接收组ID信息,数据的优先级信息,资源预留信息,重传指示信息等。数据,指的是发端在SA指示的时频资源位置,使用SA指示的格式发出的业务数据,这样,接收端能够根据SA的指示进行数据的接收。
由于本申请实施例中的第一终端接收到到第二终端发送的第一数据后,能够在确定的第一数据的反馈资源上向所述第二终端发送所述第一数据的反馈信息,因此,作为发送端的第二终端通过检测反馈信息能够确定发送的第一数据是否被成功接收,从而提高数据传输的可靠性。
下面结合附图对本申请提供的数据反馈资源的确定方案进行具体说明。
如图2所示,本申请实施例提供的数据反馈资源的确定方法,具体流程如下所示:
步骤21:第一终端接收第二终端发送的第一数据。
步骤22:所述第一终端确定所述第一数据的反馈资源。
其中,所述第一数据的反馈资源是反馈资源池中的一个反馈资源;所述反馈资源池是时频资源的集合,所述反馈资源池包括至少一个用于传输反馈信息的资源,反馈资源池的频域资源数由所述第一数据所在的数据资源池的子带数确定。
其中,所述第一终端确定所述第一数据的反馈资源包括:所述第一终端确定所述第一数据的反馈资源的时频信息和/或码域信息,所述时频信息包括频域资源起始位置信息,频域资源的长度和时域资源指示信息,所述码域信息包括发送所述反馈信息所使用的码字。
具体的,所述第一终端确定所述第一数据的反馈资源时,可以通过并不局限于以下两种实现方式,进一步的,所述第一终端可以结合以下两种实现方式确定所述第一数据的反馈资源:
第一种实现方式中:所述第一终端获取所述反馈资源池的配置信息;根据所述反馈资源池的配置信息确定所述第一数据的反馈资源。
需要说明的是,所述第一终端获取所述反馈资源池的配置信息时,可以包括以下两种情形:
第一种情形:所述第一终端从网络侧获取所述反馈资源池的配置信息,例如,可从网络侧的基站或或者中央控制器等网络侧设备获取。
第二种情形:所述第一终端通过预配置信息获取所述反馈资源池的配置信息,此时,终端从自身的预配置信息中获取。
其中,所述第一终端获取反馈资源池的配置信息,具体包括,所述第一终端获取反馈资源池的频域资源起始位置信息,频域资源长度信息,时域的子帧偏移量信息,子帧位图信息中的至少一种信息。
第二种实现方式中:所述第一终端获取所述第一数据的时频资源信息;根据所述第一数据的时频资源信息确定所述第一数据的反馈资源的时频信息。
在第二种实现方式中,反馈资源的时频位置由其相应的接收到的第一数据的时频位置确定,具体的,其中接收到的第一数据包括SA以及业务数据两部分,反馈资源的时频位 置由其相应的承载所述第一数据的SCI的时频资源确定,或者反馈资源的时频位置由其相应的接收到的第一数据中的业务数据的时频资源确定,具体的,图3A和图3B所示为反馈资源与第一数据的时频资源的对应关系示意图。
需要说明的是,所述第一终端获取的所述第一数据的时频资源信息,包括:包括承载所述第一数据的SCI的时频资源信息和/或承载所述第一数据的业务数据的时频资源信息。
在这种实现方式中,反馈资源与其相应的第一数据的时频资源存在对应关系,即由第一数据的时频位置可以确定反馈资源的时频位置,一种可能的实施方式的举例如下:
假设一个子帧内的子带(sub-channel)的索引为m(m=0,1,2,…,M-1),M为一个子帧中总的子带个数,反馈资源的索引为n(n=0,1,2,…,N-1),N为一个子帧中总的反馈资源的个数。
具体的,在频域资源的确定过程中:
如果M=N,则每个子带对应一个反馈资源,即n=m;
如果M=2N,即每两个子带对应一个反馈资源,即
Figure PCTCN2018079505-appb-000001
其中
Figure PCTCN2018079505-appb-000002
表示m/2向下取整;
以此类推,如果M=k*N,其中k表示大于等于1的整数,则每k个子带对应一个反馈资源,即
Figure PCTCN2018079505-appb-000003
具体的,在时域资源的确定过程中:
用户在子帧t接收到第一数据,则在子帧t+a发送反馈信息;其中a是大于0的预设整数,可选的,a>=4。
值得一提的是,本申请中在一个反馈资源上可以码分的方式复用多个反馈信道,因此,所述第一终端确定所述第一数据的反馈资源时,还需要确定所述第一数据的反馈资源的码域信息,具体过程为:
所述第一终端获取所述第一数据的时频资源信息,所述第一终端的ID信息,所述第二终端的ID信息中的至少一种信息,所述第一终端根据所述获取的至少一种信息确定所述第一数据的反馈资源的码域信息。
其中,在一个反馈资源上可以码分的方式复用多个反馈信道时,一种可能的实施方式的举例如下:
设在一个反馈资源上的码分资源的总数为P,P为大于0的正整数,某个用户的反馈资源p(p=0,1,…P-1)可以采用如下表达式确定:
p=f(Res data,UE ID tx,UE ID rx)
其中,p=f(x,y,z)表示p是输入变量x,y,z的函数,Res data表示数据资源的时频位置,UE ID tx表示数据发送端的ID,UE ID rx表示数据接收端的ID。
进一步的,也可以采用如下表达式确定:
p=mod(UE ID rx,P)
其中,mod()表示取余数操作。
或者,也可以采用如下表达式确定:
p=mod(UE ID tx,P)
或者,可以采用如下表达式确定:
p=mod(m,P)
其中m(m=0,1,2…M-1)表示接收到的第一数据占用的频域最低子带索引。
步骤23:所述第一终端在所述反馈资源上向所述第二终端发送所述第一数据的反馈信息,所述反馈信息用于指示所述第一数据的接收状态。
具体的,若所述第一终端成功接收到所述第一数据则向所述第二终端发送确认(ACK)消息;若没有接收到任何数据,则不向所述第二终端发送反馈信息。
或者,所述第一终端在所述反馈资源上向所述第二终端发送所述第一数据的反馈信息,所述反馈信息用于描述所述第一数据所在的传输信道的信道质量。
进一步的,所述第一终端在所述反馈资源上向所述第二终端发送所述第一数据的反馈信息时,获取第三终端发送第二数据的时域信息,如果所述第一终端确定所述第一数据的反馈资源的时域信息和所述第三终端发送所述第二数据的时域信息相同,所述第一终端延迟k个子帧发送所述第一数据的反馈信息,其中k是大于0的整数。
具体的,所述第三终端发送的第二数据可以是业务数据,也可以是反馈信息。
例如,终端A在向终端B发送反馈信息时,获得终端C,如终端C是车辆编队中的队首车辆,发送数据的时域信息;如果终端A发送反馈资源的子帧和终端C发送数据的子帧相同,则终端A延迟k(k是大于0的整数)个子帧发送反馈信息。
利用上述车联网数据反馈资源的确定方法,作为接收端的第一终端在接收到第一数据后,确定第一数据的反馈资源,在确定的反馈资源上向作为发送端的第二终端发送第一数据的反馈信息,这样作为发送端的第二终端能够确定发送的第一数据是否被成功接收,从而提高数据传输的可靠性。
上述车联网数据反馈资源的确定方法可以应用到图4所示的车辆编队行驶场景中队首车辆资源的选取过程。
在车辆编队行驶场景中,队首车辆一方面周期性的广播自己的位置、方向、速度等信息,该信息不需要接收端进行反馈。另一方面,队首车辆负责整个车队的管理,如控制车队的速度、车间距、其他车辆加入车队、车辆离开车队等,因此队首车辆需要与车队成员之间进行单播或者广播通信,并且需要车队成员进行反馈。
队首车辆有两种方式发送需要反馈的信息:
第一种方式:周期性发送,如队首车辆周期性的发送车间距信息、车速信息、加减速信息等;对于周期性发送的信息,可以沿用现有的V2X中的侦听、选取过程,在此不再赘述。
第二种方式:事件触发类的发送:如队首车辆接收到车队外的其他车辆的加入请求,队首车辆需要对该请求进行响应;或者队首车辆接收到车队内车辆的离开请求,队首车辆需要对该请求进行响应;
对于事件触发类发送的消息,可以采用如下的方式:
一种可能的实施方式中,终端有需要反馈的数据信息进行发送时,触发资源重选,终端选取可用的资源进行数据的发送;
另一种可能的实施方式中:预留资源用于传输需要反馈的数据信息,具体的,网络侧预先配置资源用于传输需要反馈的数据信息,并向终端发送预先配置资源的配置信息,终端接收配置信息,根据配置信息获取预先配置的资源,从预先配置的资源中选取资源进行数据信息的传输。
上述车联网数据反馈资源的确定方法还可以应用到车辆编队行驶场景中除队首车辆外其他车辆的资源选取过程。
在车辆编队行驶场景中,当车队中除队首车辆外的其他车辆进行资源重选时,需要考虑到队首车辆使用的资源,其他车辆的资源选取应该避免队首车辆使用的子帧,从而避免因为半双工的问题接收不到队首车辆的信息。
当终端进行资源选取时,在资源选择窗内需要排除掉的资源包括:
1.在选择窗内已经被队首车辆预留的资源。
2.在选择窗内通过预配置或者基站配置的可能用于队首车辆进行数据传输的资源。
终端在资源选取的过程中排除了可能用于队首车辆使用的子帧,从而避免了终端和队首车辆使用相同的子帧进行数据传输所导致的终端不能接收队首车辆数据的情况。
本申请实施例可以根据上述方法示例对终端进行功能单元的划分,例如,可以对应各个功能划分各个功能单元,也可以将两个或两个以上的功能集成在一个处理单元中。上述集成的单元既可以采用硬件的形式实现,也可以采用软件功能单元的形式实现。需要说明的是,本申请实施例中对单元的划分是示意性的,仅仅为一种逻辑功能划分,实际实现时可以有另外的划分方式。
