为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图1是本申请实施例适用的一种通信系统的示意图。车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的,车载终端根据基站110分配的资源在侧行链路上进行数据的发送。具体地,基站110可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。
图2是本申请实施例适用的另一种通信系统的示意图。车载终端(车载终端131和车载终端132)在侧行链路的资源上自主选取传输资源进行数据传输。可选地,车载终端可以随机选取传输资源,或者通过侦听的方式选取传输资源。
需要说明的是,设备到设备通信是基于终端到终端(Device to Device,D2D)的一种侧行链路(Sidelink,SL)传输技术,与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同,车联网系统采用终端到终端直接通信的方式,因此具有更高的频谱效率以及更低的传输时延。在3GPP定义了两种传输模式,分别记为:模式(sidelink resource allocation mode A)和第二模式(sidelink resource allocation mode B)。
模式A:终端的传输资源是由基站分配的,终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。
模式B:终端在资源池中选取一个资源进行数据的传输。
临近业务(Proximity-based Services,ProSe)涉及设备到设备的通信,主要是针对公共安全类的业务。在ProSe中,通过配置资源池在时域上的位置,例如资源池在时域上非连续,达到UE在侧行链路上非连续发送/接收数据,从而达到省电的效果。
车联网系统主要针对车车通信的场景进行了研究,其主要面向相对高速移动的车车、车人通信的业务。在V2X中,由于车载系统具有持续的供电,因此功率效率不是主要问题,而数据传输的时延是主要问题,因此在系统设计上要求终端设备进行连续的发送和接收。
可穿戴设备(FeD2D)场景,对于可穿戴设备通过手机接入网络的场景进行了研究,其主要面向是低移动速度以及低功率接入的场景。
在FeD2D中,基站可以通过一个中继(relay)终端去配置远端(remote)终端的非连续接收(Discontinuous Reception,DRX)参数。
在新空口-车辆到其他设备(New Radio-Vehicle to Everything,NR-V2X)中,支持自动驾驶,因此对车辆之间数据交互提出了更高的要求,如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在LTE-V2X系统中,支持广播传输方式,在NR-V2X系统中,引入了单播和组播的传输方式。
类似于LTE V2X系统,NR V2X系统也可以定义上述mode A/mode B两种资源授权模式。资源获取通过侧行链路授权的方式指示,即侧行链路授权指示相应的物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)与物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)资源的时频位置。
除了无反馈的、UE自主发起的混合自动请求重传(Hybrid Automatic Repeat reQuest,HARQ)重传,在NR V2X中引入了基于反馈的HARQ重传,不限于单播通信,也包括组播通信。
为便于理解本申请实施例,对本申请相关的侧行链路同步技术进行说明。
在NR-V2X系统中,同步源类型包括:eNB,gNB,全球导航卫星系统(Global Navigation Satellite System,GNSS)GNSS,UE,终端内部时钟。
在一些场景中,NR-V2X系统定义的各同步源等级如下表1所示:
表1 NR-V2X系统的同步优先级
Figure PCTCN2021143161-appb-000001
侧行传输的终端设备可能位于小区覆盖范围内或小区覆盖范围外,终端设备在小区覆盖范围内时,网络设备可以配置gNB/eNB或GNSS为更高优先级。终端设备可以根据不同的场景以及不同的配置情况确定同步源。
在一些场景中,侧行链路通信所用的资源池会被配置支持何种同步源,终端设备可以在向网络设备申请资源时,也会上报该终端设备的同步源,以便于网络设备对资源池进行合适的配置。
但是基于上述机制,存在网络设备给终端设备配置的侧行链路同步配置不合理的情况。例如,如下场景:
1、终端设备与周围的其他终端设备的同步源不同导致无法通信。
侧行链路通信系统中存在多种同步源eNB,gNB,GNSS,UE,终端内部时钟。终端设备根据网络设备配置的同步优先级及相关参数配置(例如可发送同步信号的门限,作为同步源的UE的可靠性门限)来选择同步源。如果终端设备周围存在同步于多个同步源的其他终端设备,且同步时间差别较大,则导致该终端设备无法与使用不同同步源的终端设备进行通信。
2、同步源切换频繁。
终端设备根据网络配置(例如,作为同步源的UE的可靠性门限)来判断当前使用的同步源是否可靠,若不可靠,则寻找其他可靠的同步源并切换到该可靠的同步源。若网络配置的可靠性门限不合理,会导致同步源切换频繁,进而造成侧行链路通信中断,此情况下,终端设备需重选资源,频繁与网络设备交互并向网络设备请求资源重配等。
因此,如何进行合适的侧行链路同步配置是一项亟需解决的问题。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。

在一些实施例中,测量相关信息可以包括所述终端设备执行测量的信息。
在一些实施例中,该终端设备执行测量可以指终端设备执行用于选择同步源的测量。
例如,终端设备可以对终端设备和候选同步源之间的链路的信号质量进行测量。该候选同步源可以包括但不限于网络设备,例如eNB或gNB,GNSS,其他终端设备等。
在一些实施例中,所述测量相关信息包括但不限于以下中的至少一项:
所述终端设备执行测量的时间信息;

在一些实施例中,所述测量可以指终端设备已执行的测量。终端设备在执行测量后,可以对执行测量的时间信息和/或位置信息等进行记录,进一步上报给网络设备,用于辅助网络设备给终端设备配置合适的侧行链路同步配置。
在一些实施例中,所述测量相关信息还可以包括所述终端设备执行测量选择同步源所使用的配置信息,例如,选择同步源所使用的可靠性门限。
在一些实施例中,所述侧行传输失败可以指由于侧行链路不同步导致的侧行传输失败,或者,由于侧行通信的终端设备之间的同步源不同导致的侧行传输失败。由于同步源之间可能存在不同步的问题,基于不同的同步源进行侧行传输可能导致侧行链路的不同步进而导致侧行传输失败。
在本申请一些实施例中,所述侧行传输失败相关信息包括但不限于以下中的至少一项:
所述终端设备执行侧行传输失败的时间信息;

应理解,在本申请实施例中,终端设备执行侧行传输失败的参数信息可以指用于表征终端设备之间的侧行传输失败情况的任意参数,本申请对此不作限定。
