为了便于更加清晰地理解本公开各实施例,首先对一些相关的背景知识进行如下介绍。
为了支持定位的需求,5G新空口(New Radio,NR)Uu接口定义了下行定位参考信号(Down Link Positioning Reference Signal,DL PRS),其相应的定义如下:
(1)DL PRS资源集。
(1.1)一个基站可以有一个或多个参考信号发送和接收点(Transmission Reception Point,TRP),每一个TRP可以有一个或2个DL PRS资源集,每一个DL PRS资源集是包含一个或多个DL PRS资源的集合,每一个DL PRS资源具有一个对应的DL PRS资源身份标识号(IDentity,ID);
(1.2)一个DL PRS资源集中的任意一个DL PRS资源ID与从单个TRP发送的单个波束相关联,同时,TRP可以发送一个或多个波束。
(2)DL PRS资源。
(2.1)每一个DL PRS资源配置一个Comb-N梳齿尺寸,用于在频域上将DL PRS序列映射到资源单元;
(2.2)DL PRS资源至少由以下参数描述:DL PRS资源ID、序列ID、Comb Size-N梳齿尺寸、资源粒子(Resource Element,RE)频偏、DL PRS资源的初始时隙和符号、每一个DL PRS资源的符号数(DL PRS资源的持续时间)和与其他DL参考信号的准共址(Quasi Co-Location,QCL)信息;
(2.3)DL PRS资源的符号数可以从集合{2,4,6,12}中灵活配置;
(2.4)DL PRS资源的Comb-N梳齿尺寸可以从集合{2,4,6,12}中灵活配置;
(2.5)DL PRS资源在频域上的起始物理资源块(Physical Resource Block,PRB)位置是相对于每个频率层(frequency layer)的频率参照点(Point A)来定义的。
目前在直通链路sidelink系统中还未有定位参考信号的配置,也没有基于定位参考信号进行定位的方法。
为了克服上述缺陷,本公开各实施例提供一种解决方案,能够确定为终端分配的PRS的资源配置信息,并基于PRS的资源配置信息实现对待定位终端的定位。
图1是本公开实施例提供的定位方法的流程示意图之一,如图1所示,本公开实施例提供一种定位方法,其执行主体可以为目标终端,例如,手机或车载终端等。该方法包括:
步骤101、在直通链路sidelink场景中,确定定位参考信号PRS的目标资 源配置信息;
步骤102、基于所述目标资源配置信息,对待定位终端执行定位过程;
所述目标终端包括以下任意一项或多项:
源定位终端;或
所述待定位终端。
具体地,为了克服现有技术中在sidelink场景情况下终端之间发送的定位参考信号PRS会产生冲突的缺陷,在本公开实施例中,目标终端可以首先确定定位参考信号PRS的目标资源配置信息,然后目标终端基于确定的目标资源配置信息,对待定位终端执行定位过程,不仅可以填补sidelink场景中对PRS进行资源配置,以及基于配置的PRS进行定位的空白,而且可以避免终端之间发送的PRS产生冲突,实现较高精度的定位。
可选地,目标终端可以是源定位终端。
例如,在目标终端为源定位终端的情况下,源定位终端可以首先确定PRS的目标资源配置信息,然后源定位终端基于确定的目标资源配置信息,对待定位终端执行定位过程。
例如,在车辆定位的场景下,以源定位终端为源定位车辆和待定位终端为待定位车辆为例,源定位车辆可以首先确定PRS的目标资源配置信息,然后源定位车辆基于确定的目标资源配置信息,执行对待定位车辆的定位过程。
需要说明的是,以上例子仅作为对本公开实施例的举例说明,不作为对本公开实施例的限定。
可选地,目标终端可以是待定位终端。
例如,在目标终端为待定位终端的情况下,待定位终端可以首先确定PRS的目标资源配置信息,然后待定位终端基于确定的目标资源配置信息,对待定位终端执行定位过程。
例如,在车辆定位的场景下,以源定位终端为源定位车辆和待定位终端为待定位车辆为例,待定位车辆可以首先确定PRS的目标资源配置信息,然后待定位车辆基于确定的目标资源配置信息,执行对待定位车辆的定位过程。
需要说明的是,以上例子仅作为对本公开实施例的举例说明,不作为对 本公开实施例的限定。
可选地,目标终端可以是源定位终端和待定位终端。
例如,在目标终端为源定位终端和待定位终端的情况下,源定位终端和待定位终端可以分别确定PRS的目标资源配置信息,并将各自确定的目标资源配置信息相互指示给对方;
在源定位终端和待定位终端分别确定的目标资源配置信息一致的情况下,可以基于两者确定的一致的目标资源配置信息,对待定位终端执行定位过程;
在源定位终端和待定位终端分别确定的目标资源配置信息不一致的情况下,可以基于协议预定义或配置的指示,确定使用源定位终端和待定位终端中的任意一个确定的目标资源配置信息,对待定位终端执行定位过程;或者源定位终端和待定位终端都重新确定目标资源配置信息,直至两者确定的目标资源配置信息一致,然后再基于确定的一致的目标资源配置信息对待定位终端执行定位过程。

本公开实施例提供的定位方法,通过向目标终端发送第三信息,使得目标终端可以基于第三信息确定PRS的目标资源配置信息,并基于目标资源配置信息实现对待定位终端的定位,不仅可以填补sidelink场景中对PRS进行资源配置,以及基于配置的PRS进行定位的空白,而且可以避免终端之间发送的PRS产生冲突,实现较高精度的定位。
在一个实施例中,以车辆定位的场景为例,对本公开实施例提供的定位方法进行以下说明。
假设系统预定义N个PRS资源构成一个第一资源池,其中每一个PRS资源分别表示为PRS0,PRS1,…,PRSN-1,并且此N个PRS资源的时频资源位置被所有车辆所共知。所述的被所有车辆所共知,可以根据协议将时频资源位置直接固化在车辆的芯片中,也可以通过基站或头节点(头车)进行广播告知各个车辆。而且每辆车均配置了源节点ID和/或目标节点ID,其可以是在车辆出厂时就进行配置的。
可选地,系统预定义每辆车使用的PRS资源可以由此车辆对应的源节点ID和目标节点ID经过某一运算规则确定。
例如,系统预定义每辆车使用的PRS资源的索引由车辆源节点ID与车辆目标节点ID取和之后对N取模运算获得。
假设车辆i的源节点ID表示为ID_S(i),若车辆i向目标车辆j发送PRS信号,则目标车辆j即为目标节点,且假设目标车辆j的源节点ID表示为ID_S(j),则对于车辆i,其目标节点ID即为ID_S(j)。根据系统预定义的运算规则,传输的PRS资源通过(ID_S(i)+ID_S(j))对N的取模运算确定,运算规则的表达式为mod(ID_S(i)+ID_S(j),N)。
图3是本公开实施例提供的车辆定位的示意图,如图3所示,待定位车辆1基于源定位车辆2、源定位车辆3和源定位车辆4发送的定位参考信号进行定位。假设N=10,车辆1~4的ID分别是1,2,3和4。车辆1通过物理侧边链路控制信道(Physical Sidelink Control Channel,PSCCH)发送定位参考信号触发信令或者定位请求信令,此时,车辆2~4接收到车辆1的触发信令或定位请求信令后,确定目标节点ID为ID_S(1)=1。然后,车辆2~4分别基于系统预定义的运算规则进行取模运算。
例如车辆2计算为mod(2+1,10)=3,其根据第一资源池中的PRS2的配置进行PRS传输。类似地,车辆3根据第一资源池中的PRS3的配置进行PRS传输,车辆4根据PRS4的配置进行PRS传输。待定位车辆1可以在信令指示的时刻遍历接收PRS0,PRS1,…,PRSN-1,并确定接收到PRS2,PRS3和PRS4,进而确定车辆2~4发送了定位参考信号。然后车辆1进行到达时间(Time of Arrival,TOA)的测量,并根据TOA的测量结果获得车辆1的相对位置信息。
在一个实施例中,依然以车辆定位的场景为例,对本公开实施例提供的定位方法进行以下说明。
网络侧(基站或定位服务器)确定PRS资源与车辆源节点ID的映射关系,并将此映射关系发送给其覆盖范围内的所有车辆。
例如,表3为PRS资源与车辆源节点ID之间的映射关系,如表3所示。
表3 PRS资源与车辆源节点ID之间的映射关系
可选地,网络侧将上述PRS资源与车辆源节点ID之间的映射关系发送给每一辆车。
如图3所示,待定位车辆1基于车辆2、车辆3和车辆4发送的定位参考信号进行定位。车辆1~4的ID分别是1,2,3和4。车辆1通过PSCCH信道发送定位参考信号触发信令,此时,车辆2~4接收到车辆1的触发信令后,根据上述映射关系,确定相应的PRS资源配置,并传输PRS。
例如,车辆2根据第一资源池中的PRS1的配置进行PRS传输。类似地,车辆3根据第一资源池中的PRS2的配置进行PRS传输,车辆4根据第一资源池中的PRS3的配置进行PRS传输。待定位车辆1可以在信令指示的时刻遍历接收PRS0,PRS1,…,PRSN-1,并确定接收到PRS1,PRS2和PRS3。进而确定车辆2~4发送了定位参考信号。车辆1进行到达时间TOA的测量,并根据TOA的测量结果获得车辆1的相对位置信息。
在一个实施例中,依然以车辆定位的场景为例,对本公开实施例提供的定位方法进行以下说明。
系统预定义N个PRS资源构成的第二资源池,其中每一个PRS资源分别表示为PRS0,PRS1,…,PRSN-1。对于第二资源池中的每一个资源,仅定义了部分PRS资源参数,例如第二资源池中的每一个PRS资源配置了PRS资源的带宽、PRS资源的重复因子、PRS资源占用的符号数和PRS资源的起始时间。第二资源池配置为所有车辆所共知,且每一辆车均配置了源节点ID。
网络侧设备(基站或定位服务器)确定第二资源池中每一个PRS资源的其他参数,例如确定每一个PRS资源的梳状因子、每一个PRS资源的波束方向参数,并将此参数信息发送给其覆盖范围内的所有车辆。
例如,表4为PRS资源与LMF确定的PRS资源参数之间的映射关系,如表4所示。
表4 PRS资源与LMF确定的PRS资源参数之间的映射关系

可选地,网络侧将上述PRS资源与LMF确定的PRS资源参数之间的映射关系发送给每一辆车。
系统预定义每一辆车使用的PRS资源由此车的源节点ID和目标节点ID经过某一运算规则确定。例如,系统预定义每一辆车使用的PRS资源索引由车辆源节点ID与车辆目标节点ID取和之后对N取模运算获得。假设车辆i的源节点ID表示为ID_S(i),若其向目标车辆j发送PRS信号,则目标车辆j即为目标节点。且假设目标车辆j的源节点ID表示为ID_S(j),则对于车辆i,其目标节点ID即为ID_S(j)。根据系统预定义的运算规则,传输的PRS资源通过(ID_S(i)+ID_S(j))对N的取模运算确定,运算规则的表达式为mod(ID_S(i)+ID_S(j),N)。
如图3所示,待定位车辆1基于车辆2、车辆3和车辆4发送的定位参考信号进行定位。假设N=10,车辆1~4的ID分别是1,2,3和4。车辆1通过PSCCH信道发送定位参考信号触发信令或定位请求信令,此时,车辆2~4接收到车辆1的触发信令后或定位请求信令,确定目标节点ID为ID_S(1)=1。然后,车辆2~4分别基于系统预定义的运算规则进行取模运算。
例如车辆2计算为mod(2+1,10)=3,其根据第二资源池中的PRS2的配置(PRS资源的带宽、PRS资源的重复因子、PRS资源占用的符号数、PRS资源的起始时间)同时结合基站发送的上述映射关系中的参数(梳状因子、QCL信息)进行PRS传输。类似地,车辆3根据第二资源池中的PRS3的配置同时结合基站发送的上述映射关系中的参数进行PRS传输,车辆4根据第二资源池中的PRS4的配置同时结合基站发送的PRS4的梳状因子和QCL信息进行PRS传输。待定位车辆1可以在信令指示的时刻遍历接收PRS0,PRS1,…,PRSN-1,并确定接收到PRS2,PRS3和PRS4,进而确定车辆2~4发送了定位参考信号。然后车辆1进行到达时间TOA的测量,并根据TOA的测量结果获得车辆1的相对位置信息。
在一个实施例中,依然以车辆定位的场景为例,对本公开实施例提供的 定位方法进行以下说明。
假设系统预定义N个PRS资源构成的第一资源池,其中每一个PRS资源分别表示为PRS0,PRS1,…,PRSN-1,并且此N个PRS资源的时频资源位置为所有车辆所共知。
如图3所示,待定位车辆1基于车辆2、车辆3和车辆4发送的定位参考信号进行定位。车辆1通过PSCCH信道发送定位参考信号触发信令或者定位请求信令,此时,车辆2~4接收到车辆1的触发信令或定位请求信令后,随机确定其对应的PRS资源。
例如,车辆2随机选择第一资源池中的PRS2的配置进行PRS传输,并将此选择结果通过PSCCH信道发送给车辆1。类似地,车辆3和车辆4均随机选择一个PRS资源,例如车辆3选择第一资源池中的PRS3的配置进行PRS传输,车辆4选择第一资源池中的PRS4的配置进行PRS传输。车辆3和车辆4分别通过控制信道将资源选择通知给待定位车辆1。待定位车辆1根据接收到的车辆2,3和4的PRS资源配置,接收PRS信号,基于PRS信号,进行到达时间TOA的测量,并根据TOA的测量结果获得车辆1的相对位置信息。
在一个实施例中,依然以车辆定位的场景为例,对本公开实施例提供的定位方法进行以下说明。
假设系统预定义N个PRS资源构成的第一资源池,其中每一个PRS资源分别表示为PRS0,PRS1,…,PRSN-1,并且此N个PRS资源的时频资源位置为所有车辆所共知。每一辆车均配置了源节点ID和/或目标节点ID。
可选地,系统预定义每一辆车使用的PRS资源由此车的源节点ID和目标节点ID经过某一运算规则确定。
例如,系统预定义每一辆车使用的PRS资源索引由车辆源节点ID与车辆目标节点ID取和之后对N取模运算获得。
假设车辆i的源节点ID表示为ID_S(i),若车辆i向目标车辆j发送PRS信号,则目标车辆j即为目标节点。且假设目标车辆j的源节点ID表示为ID_S(j),则对于车辆i,其目标节点ID即为ID_S(j)。根据系统预定 义的运算规则,传输的PRS资源通过(ID_S(i)+ID_S(j))对N的取模运算确定,运算规则的表达式为为mod(ID_S(i)+ID_S(j),N)。
如图3所示,待定位车辆1基于源定位车辆2、源定位车辆3和源定位车辆4发送的定位参考信号进行定位。假设N=10,车辆1~4的ID分别是1,2,3和4。车辆1通过PSCCH信道发送定位参考信号触发信令,此时,车辆2~4接收到车辆1的触发信令后,确定目标节点ID为ID_S(1)=1。然后,车辆2~4分别基于系统预定义的运算规则进行取模运算。
例如车辆2计算为mod(2+1,10)=3,其根据第一资源池中的PRS2的配置进行PRS传输。同时,源定位车辆2还将其确定的PRS2信息指示给待定位车辆1。类似地,车辆3根据第一资源池中的PRS3的配置进行PRS传输,并将PRS3信息指示给待定位车辆1,车辆4根据第一资源池中的PRS4的配置进行PRS传输,并将PRS4信息指示给待定位车辆1。待定位车辆1仅需要接收PRS2,PRS3和PRS4,进行到达时间TOA的测量,并根据TOA的测量结果获得车辆1的相对位置信息。
可选地,待定位车辆1在接收到源定位车辆发送的PRS信息指示后,可以向源定位车辆发送确认信息,表示同意源定位车辆使用相应的PRS进行传输。
可选地,待定位车辆1在接收到源定位车辆发送的PRS信息指示后,在确定不同意源定位车辆确定的PRS信息后,待定位车辆1可以自行确定期望使用的PRS信息,并指示给源定位车辆。
例如,源定位车辆2将其确定的PRS2信息指示给待定位车辆1,但待定位车辆1不同意使用PRS2,而期望源定位车辆2使用PRS8进行传输,此时待定位车辆1将PRS8信息指示给源定位车辆2,则源定位车辆2将使用PRS8进行PRS传输。
本公开实施例提供的定位方法,通过终端的ID信息和资源池的关联关系或者通过随机资源选择的方式,确定为终端分配的定位参考信号PRS资源,避免了终端间发送PRS的冲突,提供了较高精度的定位性能。
