Description

基于侧行链路的定位参考信号PRS资源确定方法和装置 技术领域
本公开涉及通信技术领域,尤其涉及一种基于侧行链路的定位参考信号PRS资源确定方法和装置。
背景技术
基于终端设备(User Equipment,UE)和UE间侧行链路(Sidelink,SL)的定位,被称为侧行链路SL定位(Sidelink positioning),侧行链路SL定位通常包括:侧行链路SL绝对定位、侧行链路SL相对定位,以及测距。侧行链路SL定位方法包括:侧行链路的往返时间(Sidelink Round Trip Time,SL RTT),侧行链路的到达时间差(Sidelink Time Difference Of Arrival,SL TDOA),侧行链路的到达角度(Sidelink Angle Of Arrival,SL AOA),SL载波相位等。进一步地,还可以将侧行链路SL定位方法与Uu定位方法(Uu定位方法,是指基于Uu接口(Uu接口是UE和基站间的无线接口)的定位)相结合,提升定位精度。如果需要获取一个UE的绝对位置,可以采用Uu定位方法获取参考UE的绝对位置,而后,获取目标UE与参考UE的相对位置,通过参考UE的绝对位置以及二者的相对位置来计算目标UE的绝对位置。被定位的UE,可以被称为目标UE(target UE),对target UE进行定位的UE,被称为锚点UE(anchor UE)。如果两个UE之间没有侧行链路SL,可以借助定位辅助UE(assistant UE),通过分别测量两个UE与定位辅助UE间的SL定位结果,获取该两个UE间的SL定位结果。
相关技术中,在侧行链路SL定位中,发送侧行链路的定位参考信号(Sidelink positioning reference signal,SL PRS)的资源(该资源例如时频域资源),与服务质量(Quality of Service,QoS)的需求有较大关系,而仅发起侧行链路SL定位的UE明确服务质量QoS的需求。
这种方式下,参与侧行链路SL定位的UE,以及在侧行链路SL定位中负责资源分配的网络设备(例如基站和/或位置管理功能(Location Management Function,LMF)),不能够有效地确定用于发送侧行链路SL的定位参考信号SL PRS的资源,从而会影响侧行链路SL定位效果。

请参见图1,图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和两个终端设备,图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定,实际应用中可以包括两个或两个以上的网络设备,一个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备101、两个终端设备102和103进行示例。

本公开实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如,网络设备101可以为演进型基站(evolved NodeB,eNB)、传输接收点(transmission reception point,TRP)、NR系统中的下一代基站(next generation NodeB,gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity,WiFi)系统中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
本公开实施例提供的网络设备可以是由集中单元(central unit,CU)与分布式单元(distributed unit,DU)组成的,其中,CU也可以称为控制单元(control unit),采用CU-DU的结构可以将网络设备,例如基站的协议层拆分开,部分协议层的功能放在CU集中控制,剩下部分或全部协议层的功能分布在DU中,由CU集中控制DU。
本公开实施例中的终端设备102和103是用户侧的一种用于接收或发射信号的实体,如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端设备(mobile terminal,MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。
本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
可以理解的是,本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案,并不构成对于本公开实施例提供的技术方案的限定,本领域普通技术人员可知,随着系统架构的演变和新业务场景的出现,本公开实施例提供的技术方案对于类似的技术问题,同样适用。
下面结合附图对本公开所提供的基于侧行链路的定位参考信号PRS资源确定方法及其装置进行详细地介绍。图2a是本公开实施例提供的一种基于侧行链路的定位参考信号PRS资源确定方法的流程示意图,该方法由第一终端设备执行。
如图2a所示,该方法可以包括但不限于如下步骤:
S102a:发起侧行链路SL定位。
其中,发起侧行链路SL定位的终端设备,可以被称为第一终端设备,第一终端设备可以是target UE、anchor UE、assistant UE中的一种,对此不做限制。
本公开实施例中,第二终端设备为进行侧行链路SL定位的终端设备,即参与侧行链路SL定位的UE可以被称为第二终端设备,第二终端设备可以是target UE、anchor UE、assistant UE中的一种,第一终端设备和第二终端设备的类型可以相同,也可以不相同,对此不做限制。
举例而言,参与侧行链路SL定位的第二终端设备,其数量可以是一个或多个,该第二终端设备为待发送侧行链路SL的定位参考信号SL PRS的终端设备。待发送侧行链路SL的定位参考信号SL PRS的第二终端设备,可以由第一终端设备基于具体的侧行链路SL定位方法确定,对此不做限制。
举例而言,测距方法,通常参与测距的两侧终端设备均具有发送SL PRS的需求;侧行链路的到达时间差SLTDOA方法,通常anchor UE具有发送SL PRS的需求;侧行链路的到达角度SL-AOA,通常target UE具有发送SL PRS的需求。另外,如果有assistant UE参与侧行链路SL定位,则assistant UE也具有发送SL PRS的需求。
S202a:向第二终端设备发送指示信息,其中,指示信息用于指示第二终端设备确定发送侧行链路SL的定位参考信号SL PRS的资源。
其中,发送侧行链路SL的定位参考信号SL PRS的资源,可以是时频域资源,用于指示发送侧行链路SL的定位参考信号SL PRS的资源的信息,可以被称为指示信息。
由于在侧行链路SL定位中,侧行链路的定位参考信号(Sidelink positioning reference signal,SL PRS)的资源(该资源例如时频域资源,用于发送SL PRS),与服务质量(Quality of Service,QoS)的需求有较大关系,而仅发起侧行链路SL定位的UE明确服务质量QoS的需求,则本公开实施例中,如果第一终端设备发起侧行链路SL定位,则可以由第一终端设备向第二终端设备发送指示信息,其中,指示信息,用于指示第二终端设备确定发送侧行链路SL的定位参考信号SL PRS的资源。
本实施例中,通过由第一终端设备发起侧行链路SL定位,并向第二终端设备发送指示信息,其中,指示信息,用于指示第二终端设备确定发送侧行链路SL的定位参考信号SL PRS的资源,使得参与侧行链路SL定位的UE,能够有效地基于指示信息来确定用于发送SL PRS的资源,有效地提升侧行链路SL定位效果。
图2b是本公开实施例提供的一种基于侧行链路的定位参考信号PRS资源确定方法的流程示意图,该方法由第一终端设备执行。
如图2b所示,该方法可以包括但不限于如下步骤:
S102b:发起侧行链路SL定位。
S202b:向网络设备发送指示信息,其中,指示信息用于指示网络设备确定发送侧行链路SL的定位参考信号SL PRS的资源。
其中,在侧行链路SL定位过程中,网络设备可以负责资源分配,或者还可以发送侧行链路SL的定位参考信号SL PRS,以支持侧行链路SL定位。
由于在侧行链路SL定位中,侧行链路的定位参考信号(Sidelink positioning reference signal,SL PRS)的资源(该资源例如时频域资源,用于发送SL PRS),与服务质量(Quality of Service,QoS)的需求有较大关系,而仅发起侧行链路SL定位的UE明确服务质量QoS的需求,则本公开实施例中,如果第一终端设备发起侧行链路SL定位,则可以由第一终端设备向网络设备发送指示信息,其中,指示信息,用于指示网络设备确定发送侧行链路SL的定位参考信号SL PRS的资源。
在一些定位场景中,可以由网络设备向第一终端设备发送定位请求,则第一终端设备可以基于该定位请求确定网络设备所指示的侧行链路的定位方法,而后第一终端设备基于侧行链路的定位方法发起侧行链路SL定位,第一终端设备可以向网络设备发送指示信息,以指示网络设备负责侧行链路SL定位过程中资源分配(比如对侧行链路SL定位过程涉及的其他任意可能的UE进行资源分配),或者指示网络设备确定出本设备发送SL PRS(用以支持侧行链路SL定位)所需的资源,对此不做限制。
在一些定位场景中,可以由第一终端设备触发发起侧行链路SL定位,而后第一终端设备可以向网络设备发送指示信息,以指示网络设备负责侧行链路SL定位过程中资源分配,或者指示网络设备确定出本设备发送SL PRS(用以支持侧行链路SL定位)所需的资源,对此不做限制。
本公开一些实施例中,网络设备可以为基站或者核心网,例如为位置管理功能。
本实施例中,通过由第一终端设备发起侧行链路SL定位,并向网络设备发送指示信息,其中,指示信息,用于指示网络设备确定发送侧行链路SL的定位参考信号SL PRS的资源,使得网络设备能够有效地基于指示信息来确定用于发送SL PRS的资源,有效地提升侧行链路SL定位效果。
应当理解,在一些可能的实施方式中,第一终端可以先发起侧行链路SL定位,再并向网络设备发送指示信息以指示网络设备确定发送侧行链路SL的定位参考信号SL PRS的资源,然而,发起侧行链路SL定位以及向网络设备发送指示信息以指示网络设备确定发送侧行链路SL的定位参考信号SL PRS的资源的顺序可以根据需要进行调整,例如同时执行,或先发送指示信息,再发起侧行链路定位。
图2c是本公开实施例提供的一种基于侧行链路的定位参考信号PRS资源确定方法的流程示意图,该方法由第一终端设备执行。
如图2c所示,该方法可以包括但不限于如下步骤:
S102c:发起侧行链路SL定位。
S202c:向第二终端设备发送指示信息,其中,指示信息用于指示第二终端设备确定发送侧行链路SL的定位参考信号SL PRS的资源,以及向网络设备发送指示信息,其中,指示信息用于指示网络设备确定发送侧行链路SL的定位参考信号SL PRS的资源。
也即是说,本公开实施例中,支持第一终端设备向第二终端设备以及网络设备发送指示信息,以指示第二终端设备以及网络设备确定发送侧行链路SL的定位参考信号SL PRS的资源。
其中,向第二终端设备发送的指示信息,用于指示第二终端设备确定出本设备发送SL PRS所需的资源,而向网络设备发送的指示信息,用于指示网络设备确定出本设备发送SL PRS所需的资源,或者指示网络设备在侧行链路SL的定位过程中负责资源分配,对此不做限制。
举例而言,可以由第一终端设备向第二终端设备和网络设备发送指示信息,具体的发送方式可以依据实际侧行链路SL定位的情况确定,对此不做限制。
本公开实施例中,第二终端设备和/或网络设备,可以基于第一终端设备发送的指示信息来确定用于发送SL PRS的资源,对此不做限制。
本实施例中,通过由第一终端设备发起侧行链路SL定位,并向第二终端设备和网络设备发送指示信息,其中,指示信息,用于指示第二终端设备和网络设备确定发送侧行链路SL的定位参考信号SL PRS的资源,使得参与侧行链路SL定位的UE,以及在侧行链路SL定位中负责资源分配的网络设备,能够有效地基于指示信息来确定用于发送SL PRS的资源,有效地提升侧行链路SL定位效果。
本公开实施例中提供的基于侧行链路的定位参考信号PRS资源确定方法,指示信息包括以下至少一项:侧行链路SL定位服务的服务质量(Sidelink Location Service Quality of Service,LCS QoS)信息;侧行链路的定位参考信号SL PRS配 置信息,能够有效地提升指示信息的指示全面性和指示效果。
其中,侧行链路SL定位服务的服务质量LCS QoS信息,能够用于描述侧行链路SL定位相关的服务质量QoS需求,而侧行链路的定位参考信号SL PRS配置信息,可以是用于对SL PRS进行信号配置。

举例而言,LCS QoS级别(LCS QoS Class),可以例如,最佳尽力级别(Best Effort Class),多服务质量级别(Multiple QoS Class),服务质量确认等级(Assured QoS Class),对此不做限制。
举例而言,LCS QoS的精度(Accuracy),可以例如,平面位置精度(Horizontal accuracy),高程精度(vertical accuracy),距离精度(distance accuracy),方位角精度(Azimuth角度精度),天顶角精度(zenith角度精度),对此不做限制。
举例而言,LCS QoS的响应时间(Response Time),Response Time,可以表示位置请求与位置响应间的最大响应时间,单位秒/毫秒等,还可以例如,无延迟(no delay),低延迟(low delay),可延迟(delay tolerant),对此不做限制。
举例而言,LCS QoS的距离范围参数(range参数)表示定位UE与被定位UE之间的距离要求,例如range参数,表示需要在该range指示的距离范围内满足精度要求。
本公开一些实施例中,网络设备可以为基站或者核心网,例如为位置管理功能。
