背景技术
车联网系统是基于设备到设备(D2D,Device to Device)的侧行链路(SL,Sidelink)传输技术,与传统的长期演进(LTE,Long Term Evolution)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。
在第三代合作伙伴计划(3GPP,Third Generation Partner Project)版本14(Rel-14)中对车联网技术(V2X,Vehicle-to-Everything)进行了标准化,定义了两种传输模式:模式3和模式4。在模式3中,终端的传输资源由基站分配。在模式4中,终端采用侦听(sensing)和预留(reservation)的方式确定传输资源。
在新无线车联网(NR-V2X,New Radio Vehicle-to-Everything)中,需要支持自动驾驶,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、更高的定位精度等。在NR-V2X中,对车辆的定位精度的要求是定位误差小于1米。为了提高车辆的定位精度,车辆可以发送定位参考信号以辅助其他车辆进行定位。车辆如何发送定位参考信号是需要解决的问题。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。

该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端120。作为在此使用的“终端”包括但不限于经由有线线路连接,如经由公共交换电话网络(Public  Switched Telephone Networks,PSTN)、数字用户线路(Digital Subscriber Line,DSL)、数字电缆、直接电缆连接;和/或另一数据连接/网络;和/或经由无线接口,如,针对蜂窝网络、无线局域网(Wireless Local Area Network,WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器;和/或另一终端的被设置成接收/发送通信信号的装置;和/或物联网(Internet of Things,IoT)设备。被设置成通过无线接口通信的终端可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话;可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System,PCS)终端;可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System,GPS)接收器的PDA;以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端或者未来演进的PLMN中的终端等。
可选地,终端120之间可以进行终端直连(Device to Device,D2D)通信。
可选地,5G系统或5G网络还可以称为新无线(New Radio,NR)系统或NR网络。

应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
为便于理解本申请实施例的技术方案,以下分别对车联网中的模式3和模式4进行解释说明。
模式3:如图2所示,车载终端的侧行链路传输资源是由基站(如LTE中的演进基站(eNB,evolved NodeB))分配的,具体地,基站通过下行链路(DL,Down Link)向车载终端下发用于指示授权(Grant)资源的控制消息;而后,车载终端根据基站分配的资源在SL上进行数据的发送。在模式3中,基站可以为车载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4:如图3所示,车载终端采用侦听和预留的传输方式获取侧行链路的传输资源。车载终端在资源池中通过侦听的方式获取可用的传输资源集合,车载终端从该传输资源集合中随机选取一个资源进行侧行链路数据的传输。由于车联网系统中的业务具有周期性特征,因此车载终端通常采用半静态传输的方式,即车载终端选取一个传输资源 后,就会在多个传输周期中持续的使用该资源,从而降低资源重选以及资源冲突的概率。车载终端会在本次传输的控制信息中携带预留下次传输资源的信息,从而使得其他终端可以通过检测该车载终端的控制信息判断这块资源是否被该车载终端预留和使用,达到降低资源冲突的目的。
需要说明的是,在LTE-V2X中分别使用模式3表示车载终端的传输资源是由基站分配的,用模式4表示车载终端的传输资源是终端自主选取的,在NR-V2X中,可以定义新的传输模式,本申请对此不做限定。
图4为本申请实施例提供的信号传输方法的流程示意图,如图4所示,所述信号传输方法包括以下步骤:
步骤401:第一终端确定第一时刻,所述第一终端在所述第一时刻发送第一信号,其中,所述第一信号是定位参考信号。
本申请实施例中,所述第一终端可以是手机、平板电脑、车载终端、可穿戴式设备、笔记本等任意能够与网络进行通信的设备。
在一实施方式中,所述第一终端在第二时刻获得同步信息;所述第一终端在所述第二时刻之后的第一时间范围内确定所述第一时刻。其中,所述同步信息的获取方式可以是:
1)所述同步信息来自于全球导航卫星系统(GNSS,Global Navigation Satellite System)的同步信号;或者,
2)所述同步信息来自于网络设备的同步信号;或者,
3)所述同步信息来自于第三终端发送的侧行同步信号。
对于上述2),网络设备可以是基站,例如:第一终端接收基站发送的主同步信号(PSS,Primary Synchronization Signal)和/或辅同步信号(SSS,Secondary Synchronization Signal)。
对于上述3),第三终端可以与第一终端的类型相同,也可以与第一终端的类型不同,例如第一终端为手机、第二终端为车载终端,再例如,第一终端和第二终端都是车载终端。第一终端与第二终端可以直接进行通信,具体地,第一终端接收第三终端通过侧行链路发送的侧行同步信号(SLSS,Sidelink Synchronization Signal)。
本申请实施例中,第一终端在第二时刻获得同步信息,例如:第一终端在时刻n获得同步信息,这里,第二时刻的单位可以是绝对时间,也可以是时域时间,例如子帧、时隙、时域符号、短时传输间间隔(sTTI,short Transmission Time Interval)等。
本申请实施例中,第一终端在第二时刻获得同步信息后,在第一时刻发送第一信号,其中,所述第一时刻是位于所述第二时刻之后的第一时间范围内的一个时刻,第一时刻的单位可以是绝对时间,也可以是时域时间,例如子帧、时隙、时域符号、sTTI等。这里,第一终端发送第一信号的对象可以是终端,也可以是网络设备,举个例子:第一终端通过侧行链路向其他终端发送定位参考信号。再举个例子:第一终端通过上行链路向网络设备(如基站)发送定位参考信号。
举例来说,第一终端在子帧0接收到网络发送的同步信号,在子帧范围[1,9]内选取子帧4作为第一时刻,并且在子帧4通过侧行链路发送定位参考信号,其中,子帧0即为第二时刻,子帧范围[1,9]即为第一时间范围,子帧4即为第一时刻。
本申请实施例中,第一终端可以通过如下方式确定第一时刻:
1)所述第一终端获得第一指示信息,根据所述第一指示信息确定所述第一时刻。
这里,所述第一终端根据预配置信息获得所述第一指示信息;或者,

在一实施例中,所述第一指示信息用于指示时间索引信息,第一终端可以根据预配置信息,或者网络配置信息,或者从第二终端获得该时间索引信息,并且根据将该时间索引信息对应的时刻确定为所述第一时刻。可选地,第一终端可以不需要获得同步信息。可选地,第一终端不需要确定第一时间范围。
举个例子,所述第一指示信息包括时间索引信息m,第一终端在时间索引与时刻对应关系中可以确定时间索引信息m对应的时刻,将该时刻作为发送所述第一信号的第一时刻。
1.2)所述第一指示信息用于指示时间偏移信息,所述时间偏移信息是所述第一时刻相对于所述第二时刻的时间偏移量;所述第一终端基于所述时间偏移信息和所述第二时刻,确定所述第一时刻。或者,所述时间偏移信息是所述第一时刻相对于一个时间单元的时间偏移量;所述第一终端基于所述时间偏移信息和所述时间单元,确定所述第一时刻。
举个例子:所述第一指示信息包括时间偏移信息k=5,那么,第一终端在第二时刻获得同步信息后,在第二时刻后的第5个时间单元发送所述第一信号,假设第一终端在时隙n获得同步信息,那么,在时隙n+5发送所述第一信号。
再举个例子:所述第一指示信息包括时间偏移信息k=5,该时间偏移是相对于无线帧中子帧0的时间偏移量,因此,第一终端确定每个无线帧中的子帧5为第一时刻,并且在该子帧发送所述第一信号。
2)所述第一终端在所述第一时间范围内选取一个时刻作为所述第一时刻。其中,
2.1)所述第一终端在所述第一时间范围内随机选取一个时刻作为所述第一时刻;或者,

进一步,所述第一标识信息包括以下至少之一:所述第一终端的小区无线网络临时标识(C-RNTI,Cell-Radio Network Tempory Identity)、所述第一终端所在组的组内标识、用于区分所述第一终端的其他标识信息。
举个例子:所述第一终端属于一个通信组,该通讯组包括10个终端,所述10个终端在该组内的标识分别对应索引[0,9],所述第一终端对应的索引为4,第一时间范围包括10个子帧,所述第一终端可以根据下面的方式在第一时间范围内确定所述第一时刻:t=mod(ID,N)
其中,ID表示第一终端在该组内的组内标识,即索引4,N表示第一时间范围内的子帧总数,即N=10,t表示用于所述第一终端发送第一信号的第一时刻,mod()表示取余数运算。
3)所述第一终端获取资源池的配置信息,根据所述资源池的配置信息确定所述第一时刻,其中,所述第一时刻是所述资源池内的传输时刻。
举个例子,资源池的配置信息包括4个传输资源,分别为资源1、资源2、资源3、资源4,其中,资源1对应的时间为t1,资源2对应的时间为t2,资源3对应的时间为t3,资源4对应的时间为t4,第一终端在时刻n获得同步信息后,从资源池中选取一个位于时刻n之后的第一个可用时刻作为发送所述第一信号的所述第一时刻, 资源2对应的时刻t2是位于时刻n之后的第一个可用时刻,第一终端在时刻t2上发送所述第一信号。可选地,第一终端根据所述资源池的配置信息确定时刻t2对应的频域资源范围,所述第一信号占据该时刻t2的全部频域资源。
特别地,所述第一终端获取资源池的配置信息,如果所述第一终端根据所述第一指示信息所确定的所述第一时刻或者所述第一终端在所述第一时间范围内选取的所述第一时刻(即通过上述方式1)和方式2)所确定的第一时刻),不在所述资源池内,则所述第一终端将所述第一时刻之后的并且位于所述资源池之内的第一个可用时刻作为发送所述第一信号的所述第一时刻。
举个例子:资源池的配置信息包括4个传输资源,分别为资源1、资源2、资源3、资源4,其中,资源1对应的时间为t1,资源2对应的时间为t2,资源3对应的时间为t3,资源4对应的时间为t4,通过上述方式1)中的第一指示信息,第一终端确定在时刻m(对应第一时刻)发送所述第一信号,但是如果时刻m不在所述资源池内,则第一终端从资源池中选取一个位于时刻m之后的第一个可用时刻作为发送所述第一信号的所述第一时刻,如果资源1对应的时刻t1是位于时刻m之后的第一个可用时刻,第一终端在时刻t1上发送所述第一信号。可选地,第一终端根据所述资源池的配置信息确定时刻t1对应的频域资源范围,所述第一信号占据该时刻t1的全部频域资源。
4)所述第一终端获取第二指示信息,所述第二指示信息用于确定第一预留时刻的时域位置,所述第一终端将所述第一预留时刻作为发送所述第一信号的所述第一时刻;其中,所述预留时刻是指不用于传输侧行链路数据的时刻。
这里,第一预留时刻的单位可以是绝对时间,也可以是时域时间,例如子帧、时隙、时域符号、sTTI等。
所述第一终端根据预配置信息获得所述第二指示信息;或者,所述第一终端根据网络配置信息获得所述第二指示信息;或者,所述第一终端接收第三终端发送的所述第二指示信息。
举个例子:第一终端获取第二指示信息,所述第二指示信息指示每个无线帧中的最后一个子帧,即子帧9,是预留子帧,因此,第一终端将每个无线帧中的子帧9确定为第一时刻,并且在该子帧发送所述第一信号。
可选地,所述第一预留时刻是所述第一时间范围内的一个预留时刻。
举个例子:所述第一终端在时刻n接收到同步信息,第一时间范围为时刻[n+1,n+k],需要注意的是,k的单位与n的单位需要保持一致,例如都是时隙或子帧,第一预留时刻为时刻n+3,n+3≤n+k,时刻n+3不用于传输侧行链路数据,如物理侧行控制信道(PSCCH,Physical Sidelink Control Channel)或物理侧行共享信道(PSSCH,Physical Sidelink Shared Channel)或物理侧行广播信道(PSBCH,Physical Sidelink Broadcast Channel),第一终端在时刻n+3上发送所述第一信号。
本申请实施例中,所述第一终端获取第一信息,根据所述第一信息确定所述第一时间范围。可选地,所述第一信息用于确定定位精度信息,具体的,所述第一信息包括以下至少之一:定位精度信息、定时误差信息、频率偏差信息、服务质量(Qos,Quality of Service)信息、服务质量等级标识(QCI,QoS Class Identifie)信息。
这里,所述QoS信息或QCI信息用于确定定位精度信息,基于此,第一终端可以依据所述QoS信息或QCI信息来确定定位精度信息。
举个例子,第一终端在时刻n获得同步信息,在第一时间范围[n+1,n+k]内确定用于传输所述第一信息的第一时刻,这里,k的取值根据定位精度信息确定,k的取值越大,表明定位精度越低,反之,k的取值越小,表明定位精度越高。
