Description
本申请要求申请日为2020年2月25日、申请号为PCT/CN2020/076652、发明名称为“信息发送方法、信息接收方法、装置、设备及存储介质”的PCT申请的优先权
本申请涉及移动通信领域,特别涉及一种信息发送方法、信息接收方法、装置、设备及存储介质。
为了实现车联网(Vehicle to everything,V2X)***中的终端设备之间的直接通信,引入了侧行链路(SideLink,SL)传输方式。
在SL的一种传输模式中,网络设备向终端设备A分配侧行资源,终端设备A采用侧行资源向终端设备B发送侧行数据1。若终端设备B未能正确接收侧行数据1,则终端设备B向终端设备A发送否认应答(NACK)。终端设备A向网络设备转发NACK,网络设备向终端设备A分配重传资源。
由于终端设备A在侧行资源上传输哪一个侧行数据是自行决策的,因此当终端设备A在侧行资源上传输侧行数据2,且侧行数据2不需要侧行反馈时,上行资源将被浪费。

为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
首先,对本申请实施例中涉及的名词进行简单介绍:
车联网(Vehicle to everything,V2X):是未来智能交通运输***的关键技术,主要研究基于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,V2V)通信、车与路侧基础设施(Vehicle to Infrastructure,V2I)通信以及车与行人(Vehicle to People,V2P)通信。V2X应用将改善驾驶安全性、减少拥堵和车辆能耗、提高交通效率等。
侧行链路(SideLink,SL)传输:是一种终端设备到终端设备的通信方式,具有较高的频谱效率和较低的传输时延。在3GPP中定义了两种侧行链路的传输模式:模式A和模式B。如图1中的(1)所示,模式A中,终端设备的传输资源是由网络设备(比如基站)通过下行链路DL分配的,终端设备根据基站分配的资源在侧行链路上进行数据的发送;网络设备可以为终端设备分配单次传输的资源(动态分配),也可以为终端设备分配半静态传输的资源。如图1中的(2)所示,模式B中,终端设备在资源池中自行选取一个侧行资源进行数据的传输。具体的,终端设备可以通过侦听的方式在资源池中选取侧行资源,或者通过随机选取的方式在资源池中选取侧行资源。
在LTE-V2X中,支持广播传输方式,在NR-V2X中,引入了单播和组播的传输方式。对于单播传输,其接收端终端只有一个终端,如图2中,用户设备(UserEquipment,UE1)和UE2之间进行单播传输;对于组播传输,其接收端是一个组播组内的所有UE,或者是在一定传输距离内的所有终端,如图3,UE1、UE2、UE3和UE4构成一个组播组,其中UE1发送数据,该组内的其他UE都是接收端终端;对于广播传输方式,其接收端是任意一个终端,如图4,其中UE1是发送端终端,其周围的其他UE都是接收端终端。。
侧行配置授权(Configured Grant,CG)
在新无线(New Radio,NR)-V2X中,支持模式1和模式2的信息发送方式。在模式2中,终端在资源池自主选取侧行资源进行侧行传输,即图1所示的模式B;在模式1中,网络为终端设备分配侧行资源,即图1所示的模式A。具体的,网络设备可以通过动态调度(Dynamic Scheduling)的方式为终端设备分配侧行资源;或者网络设备可以为终端设备分配侧行配置授权(SL CG)侧行资源。对于CG的信息发送方式,主要包括两种配置授权方式:type-1configured grant(第一类配置授权)和type-2configured grant(第二类配置授权)
第一类配置授权:网络设备通过无线资源控制(RadioResourceControl,RRC)信令为终端设备配置侧行资源,该RRC信令配置包括时域资源、频域资源、解调参考信号(Demodulation Reference Signal,DMRS)、调制编码方案(Modulation and Coding Scheme,MCS)等在内的全部侧行资源和传输参数。当UE接收到该高层参数后,可立即使用所配置的传输参数在配置的时频资源上进行侧行传输。
第二类配置授权:采用两步的资源配置方式,即RRC+下行控制信息(DownlinkControlInformatica,DCI)的方式;首先,由RRC信令配置包括时频资源的周期、混合自动重传(Hybrid Automatic Repeat reQuest,HARQ)进程数等在内的侧行资源和传输参数,然后由DCI激活第二类配置授权的传输,并同时配置包括时域资源、频域资源、MCS等在内的其他侧行资源和传输参数。UE在接收到RRC信令时,不能立即使用该高层参数配置的资源和参数进行侧行传输,而必须等接收到相应的DCI激活并配置其他资源和传输参数后,才能进行侧行传输。此外,网络设备可以通过DCI去激活该配置传输,当终端设备接收到去激活的DCI后,不能再使用该侧行资源进行侧行传输。
如果网络设备为终端设备分配了第二类配置授权的侧行资源,当终端设备有侧行数据要传输时,可以直接使用该侧行资源进行传输,而不需要向网络设备发送调度请求(Scheduling Request,SR)/缓冲区状态报告(Scheduling Request,BSR)请求侧行资源,从而降低时延。
侧行反馈信道(Physical Sidelink Feedback Channel,PSFCH):
在NR-V2X中,为了提高可靠性,引入了侧行反馈信道。例如,对于单播传输,发送端终端向接收端终端发送侧行数据(包括PSCCH和PSSCH),接收端终端向发送端终端发送HARQ反馈信息,发送端终端根据接收端终端的反馈信息判断是否需要进行重传。其中,HARQ反馈信息承载在侧行反馈信道中,例如,HARQ反馈信息包括确认ACK或者否定确认NACK。
可以通过预配置信息或者网络设备配置信息激活或者去激活侧行反馈,如果侧行反馈被激活,则接收端终端接收发送端终端发送的侧行数据,并且根据检测结果向发送端反馈HARQ ACK或者NACK,发送端终端根据接收端的反馈信息决定发送重传数据或者新数据,如图5所示;如果侧行反馈被去激活,接收端终端不需要发送反馈信息,发送端终端通常采用盲重传的方式发送数据,例如,发送端终端对每个侧行数据重复发送K次,K为大于等于1的整数,而不是根据接收端终端的反馈信息决定是否需要发送重传数据。
在模式1中,网络设备为终端设备分配侧行资源,如果发送端终端使用该资源传输支持侧行反馈的侧行数据,接收端向发送端发送侧行反馈信息,发送端将该侧行反馈信息上报给网络设备,网络设备根据该发送端上报的侧行反馈信息决定是否需要分配重传资源。
具体的,网络设备可以为终端设备分配PUCCH资源,该PUCCH侧行资源用于发送端终端向网络设备上报侧行反馈信息。
如图6所示,UE1是发送端UE,UE2是接收端UE,gNB为UE1分配侧行资源,并且分配了PUCCH 的侧行资源,UE1在网络设备分配的侧行资源上向UE2发送侧行数据PSCCH/PSSCH,UE2根据侧行数据的检测结果向UE1发送侧行反馈信息(如在PSFCH上发送HARQ-ACK),用于指示该侧行数据是否被正确接收,UE1将该侧行反馈信息通过PUCCH上报给网络设备,网络设备根据UE1上报的侧行反馈信息决定是否为UE1分配重传资源。
但是在网络设备为终端设备分配了侧行资源后,是由终端设备决定使用该侧行资源传输哪种侧行数据,例如,可以传输第一类型的侧行数据,该第一类型的侧行数据需要接收端终端发送侧行反馈,例如在终端设备发送的SCI中携带指示信息,用于指示接收端终端发送侧行反馈。终端设备也可以传输第二类型的侧行数据,该第二类型的侧行数据不需要接收端终端发送侧行反馈,但是由于网络设备为该终端设备分配了上行资源,用于该终端设备向网络设备上报侧行反馈,此时终端设备在该上行资源上如何上报侧行反馈是需要解决的问题。
图7示出了本申请一个示例性实施例提供的信息发送方法的流程图。本实施例以该方法应用于图1所示的通信***来举例说明。该方法包括:
步骤102,终端设备在侧行资源上传输的侧行数据不需要侧行反馈的情况下,在上行资源上向网络设备发送NACK;
传输资源是网络设备向终端设备分配的资源,即终端设备工作在模式1,侧行资源都是由网络设备分配的。传输资源包括侧行资源和上行资源中的至少一种。其中,侧行资源用于发送侧行数据的初传和/或重传,上行资源用于发送侧行数据的反馈(ACK或NACK)。侧行数据是终端设备自行决定在侧行资源上传输的数据。本实施例,以传输资源包括侧行资源和上行资源为例来说明。
由于在侧行传输资源上传输哪种侧行数据是终端设备自行决定的,在一种可能的情况下,侧行数据是第一类型的侧行数据,第一类型的侧行数据是需要接收端终端进行侧行反馈的数据;在另一种可能的情况下,侧行数据是第二类型的侧行数据,第二类型的侧行数据是不需要接收端终端进行侧行反馈的数据。
若网络设备为终端设备分配了侧行传输资源,并且分配了上行资源,终端设备在侧行资源上发送第二类型的侧行数据,终端设备可以进行多次重复传输以提高数据传输的可靠性,,但是在网络终端为终端设备分配侧行资源的情况下,所有的侧行资源都是网络设备分配的,因此终端设备在上行资源上向网络设备发送NACK。
步骤104,网络设备接收终端设备在上行资源上发送的NACK,NACK是终端设备在侧行资源上传输的侧行数据不需要侧行反馈的情况下发送的;
上行资源可以是物理上行控制信道(PhysicalUplinkControlChannel,PUCCH)上的资源。该上行资源是与侧行资源对应的资源,例如PUCCH传输资源与侧行传输资源之间的时间间隔是根据网络配置信息确定的。
步骤106,网络设备根据NACK向终端设备分配侧行数据的重传资源。
网络设备接收到NACK,该信息表示侧行数据没有被正确接收,或者表示终端设备需要重传该侧行数据,或者表示终端设备需要被分配侧行资源。
网络设备在接收到NACK的情况下,继续向终端设备分配侧行资源;可选地,该侧行资源用于重传该侧行数据。
需要说明的是,步骤102至步骤106可以执行多次。
示例性的参考图8,在时刻n,终端设备A存在侧行数据到达,需要传输该侧行数据。假设该侧行数据是不需要侧行反馈的数据,终端设备A向网络设备发送SR/BSR来申请侧行资源,网络设备向终端设备A分配2个侧行资源和1个PUCCH资源,该2个侧行资源的时域位置分别对应(n+6)ms和(n+9)ms,PUCCH资源的时域位置为(n+12)ms,终端设备A使用第一个侧行资源(n+6)ms发送侧行数据的初传,使用第二个侧行资源(n+9)ms发送侧行数据的重传。并且,终端设备A在PUCCH资源上向网络设备上报NACK,以触发网络设备继续为该终端设备A调度该侧行资源的重传资源。
综上所述,本实施例提供的方法,通过终端设备在侧行资源上传输的侧行数据不需要侧行反馈的情况下,在上行资源上向网络设备发送NACK,该NACK用于触发网络设备向终端设备分配侧行数据的重传资源。因此,在侧行数据不需要侧行反馈的情况下,本申请也能够有效利用上行资源,使得网络设备能够根据NACK向终端设备分配侧行数据的重传资源,提高了侧行数据的传输成功率和上行资源的资源利用率。
图9示出了本申请另一个示例性实施例提供的信息发送方法的流程图。本实施例以该方法应用于图1所示的通信***来举例说明。该方法包括:
步骤202,网络设备向终端设备发送第一配置信息,第一配置信息用于分配侧行资源和上行资源;
在一个示例中,终端设备中存在侧行数据需要发送的情况下,终端设备向网络设备发送SR或BSR。网络设备接收终端设备发送的SR或BSR,根据SR或BSR向终端设备分配传输资源。
示例性的,传输资源包括侧行资源和上行资源中的至少一种。在本实施例中,以传输资源包括侧行资源和上行资源为例来举例说明。其中,侧行资源用于发送侧行数据的初传和/或重传,上行资源用于发送侧 行数据的反馈(ACK或NACK)。侧行数据是终端设备自行决定在侧行资源上传输的数据,比如不需要侧行反馈的侧行数据。
在一个示例中,第一配置信息是下行控制信息(DownlinkControlInformation,DCI),网络设备向终端设备发送DCI,该DCI用于分配侧行资源和上行资源。
在一个示例中,第一配置信息是侧行配置授权,网络设备向终端设备发送侧行配置授权,该侧行配置授权用于分配侧行资源和上行资源。
可选地,上行资源是指PUCCH资源。
步骤204,终端设备接收网络设备发送的第一配置信息,第一配置信息用于分配侧行资源和上行资源;
在一个示例中,终端设备接收网络设备发送的DCI,该DCI用于分配侧行资源和上行资源。
在一个示例中,终端设备接收网络设备发送的侧行配置授权,该侧行配置授权用于分配侧行资源和上行资源。
步骤206,终端设备在侧行资源上传输的侧行数据不需要侧行反馈且传输资源满足时延要求的情况下,在上行资源上向网络设备发送NACK;
传输资源满足时延要求是指:侧行资源和上行资源的时域位置均不超过侧行数据的时延要求对应的时域位置。时延要求对应的时域位置是指“侧行数据的业务到达时刻+时延要求”所指示的时刻。
该NACK用于触发网络设备向终端设备分配侧行数据的重传资源。
步骤208,网络设备接收终端设备在上行资源上发送的NACK,NACK是终端设备在侧行资源上传输的侧行数据不需要侧行反馈且传输资源满足时延要求的情况下发送的;
步骤210,网络设备根据NACK向终端设备分配侧行数据的重传资源;
在一个示例中,网络设备在接收到NACK的情况下,向终端设备分配侧行资源;可选地,该侧行资源用于重传该侧行数据。
在一个示例中,网络设备在接收到NACK且该侧行数据的传输次数未达到最大传输次数的情况下,向终端设备分配侧行数据的重传资源;在接收到NACK且该侧行数据的传输次数达到最大传输次数的情况下,不向终端设备分配侧行数据的重传资源。也即,网络设备结合该侧行数据的最大传输次数,来综合决策是否继续分配重传资源。
需要说明的一点是,步骤206至步骤210可以执行多次。
步骤212,终端设备在传输资源的时域位置超过侧行数据的时延要求对应的时域位置的情况下,在上行资源上向网络设备发送ACK;
终端设备在侧行资源的时域位置超过侧行数据的时延要求对应的时域位置的情况下,在上行资源上向网络设备发送ACK;和/或,终端设备在上行资源的时域位置超过侧行数据的时延要求对应的时域位置的情况下,在上行资源上向网络设备发送ACK。
步骤214,网络设备接收终端设备在上行资源上发送的ACK;
步骤216,网络设备根据ACK终止向终端设备分配侧行数据的重传资源。
综上所述,本实施例提供的方法,通过终端设备在侧行资源上传输的侧行数据不需要侧行反馈的情况下,在上行资源上向网络设备发送NACK,该NACK用于触发网络设备向终端设备分配侧行数据的重传资源。因此,在侧行数据不需要侧行反馈的情况下,本申请也能够有效利用上行资源,使得网络设备能够根据NACK向终端设备分配侧行数据的重传资源,提高了侧行数据的传输成功率和上行资源的资源利用率。
本实施例提供的方法,还通过终端设备在传输资源的时域位置超过侧行数据的时延要求对应的时域位置的情况下,向网络设备发送上行信息,该上行信息用于终止网络设备向终端设备分配侧行数据的重传资源,使得在网络设备分配的侧行资源不满足业务的时延要求时,无需再向终端设备继续分配重传资源,避免了无效的重传资源的分配,减少了通信资源的浪费。

结合图10,由于在初次的传输资源的分配过程中,以及后续的多次重传资源的分配过程中,网络设备分配的侧行资源和/或上行资源可能会不满足侧行数据的时延要求。上述步骤310可替代实现成为如下子步骤,如图11所示。该方法包括:

综上所述,本实施例提供的方法,通过终端设备根据侧行数据的第一参数和对应关系,在上行资源上向网络设备发送ACK或NACK,能够在侧行数据的传输次数未达到最大传输次数的情况下,不断请求网络设备分配侧行数据的重传资源,从而实现不同重要程度的侧行数据,实现不同次数的重复传输,提高了不需要侧行反馈的侧行数据的传输成功率。
结合图12,由于在初次的传输资源的分配过程中,以及后续的多次重传资源的分配过程中,网络设备分配的侧行资源和/或上行资源可能会不满足侧行数据的时延要求。上述步骤410可替代实现成为如下子步骤,如图13所示。该方法包括:
步骤410-1,在侧行数据的传输次数未达到最大传输次数的情况下,终端设备根据接收到的侧行反馈信息,在上行资源上向网络设备发送第一信息,第一信息包括ACK或NACK;
示意性的,在终端设备接收到的侧行反馈信息是ACK时,在上行资源上向网络设备发送ACK;在终端设备接收到的侧行反馈信息是NACK时,在上行资源上向网络设备发送NACK;在终端设备的判断结果是DTX,DTX是指发送端没有接收到接收端发送的侧行反馈信息或没有检测到接收端发送的侧行反馈信道时,在上行资源上向网络设备发送NACK。

图14示出了本申请一个示例性实施例提供的信息发送方法的流程图。本实施例以该方法应用于图7所示的通信***来举例说明。该方法包括:
步骤502,终端设备在传输资源的时域位置超过侧行数据的时延要求对应的时域位置的情况下,向网络设备发送ACK;
终端设备确定传输资源的时域位置超过侧行数据的时延要求对应的时域位置,且向网络设备发送上行信息。其中,上行信息用于终止网络设备向终端设备分配侧行数据的重传资源。
传输资源是网络设备向终端设备分配的资源。传输资源包括侧行资源和上行资源中的至少一种。其中,侧行资源用于发送侧行数据的初传和/或重传,上行资源用于发送侧行数据的反馈(ACK或NACK)。侧行数据是终端设备自行决定在侧行资源上传输的数据。

步骤504,网络设备接收来自终端设备的ACK;
步骤506,网络设备根据上行信息终止向终端设备分配侧行数据的重传资源。
在接收到与侧行资源对应的上行信息后,网络设备终止向终端设备分配侧行数据的重传资源。
示例性的参考图15,在时刻n,终端设备A存在侧行数据到达,需要传输该侧行数据。假设该侧行数据对应的时延需求是10毫秒(ms),即该侧行数据的包延迟预算(Packet Delay Budget,PDB)是10ms,因此终端设备A向网络设备发送SR/BSR来申请侧行资源,网络设备向终端设备A分配3个侧行资源和1个PUCCH资源,该3个侧行资源的时域位置分别对应(n+6)ms、(n+9)ms和(n+12)ms,终端设备A使用第一个侧行资源(n+6)ms发送侧行数据的初传,使用第二个侧行资源(n+9)ms发送侧行数据的重传。如果终端设备A收到终端设备B发送的NACK,终端设备A应该发送侧行数据的重传,但是由于第三个侧行资源的时域位置(n+12)ms已经超过了该侧行数据的时延需求,因此终端设备A不会使用该侧行资源(n+12)ms发送重传,并且在PUCCH资源上向网络设备上报上行信息,以终止网络设备为该终端设备A调度重传资源。
示例性的参考图16,在时刻n,终端设备A存在侧行数据到达,需要传输该侧行数据。假设该侧行数据对应的时延需求是15毫秒(ms),即该侧行数据的包延迟预算(Packet Delay Budget,PDB)是15ms,因此终端设备A向网络设备发送SR/BSR来申请侧行资源,网络设备向终端设备A分配3个侧行资源和1个PUCCH资源,该3个侧行资源的时域位置分别对应(n+6)ms、(n+9)ms和(n+12)ms,PUCCH资源的时域位置对应(n+16)ms,终端设备A使用第一个侧行资源(n+6)ms发送侧行数据的初传,使用第二个侧行资源(n+9)ms和第三个侧行资源(n+12)ms发送侧行数据的重传。如果终端设备A收到终端设备B发送的NACK,终端设备A应该发送侧行数据的重传,但是由于PUCCH资源的时域位置已经超过了该侧行数据的时延需求,即便再次分配重传资源,也是无效的重传资源。因此终端设备A不会使用该PUCCH资源向网络设备上报NACK,而是使用该PUCCH资源向网络设备上报上行信息,以终止网络设备为该终端设备A调度重传资源。
综上所述,本实施例提供的信息发送方法,通过终端设备在传输资源的时域位置超过侧行数据的时延要求对应的时域位置的情况下,向网络设备发送上行信息,该上行信息用于终止网络设备向终端设备分配侧行数据的重传资源,使得在网络设备分配的侧行资源不满足业务的时延要求时,无需再向终端设备继续 分配重传资源,避免了无效的重传资源的分配,减少了通信资源的浪费。
需要说明的是,上述各个实施例中由终端设备执行的步骤,可单独实现成为终端设备侧的信息发送方法;由网络设备执行的步骤,可单独实现成为网络设备侧的信息接收方法。
需要说明的是,上述各个实施例还可以根据本领域技术人员的理解,自由组合出新的实施例。
需要说明的是,上述侧行数据可以为多个,每个侧行数据对应不同的传输资源,每个传输资源对应不同的ACK或NACK,不同的ACK或NACK可以用“第一、第二”等区分。
