背景技术
LTE(Long Term Evolution,长期演进)系统中引入了定位参考信号(PRS,Positioning Reference Signalling),专用于OTDOA(Observed Time Difference of arrival,观察到达时差)定位方法中终端测量基站信号,终端通过测量定位参考信号,获取3个不同基站信号到达的时间差来确定终端的位置,获取定位信息。
相关技术中的Rel-15(phase 1,第一阶段)的5G(5-Generation,第五代移动通信技术)NR(new radio,新空口)的设计尚不支持基于终端辅助的定位技术,具体地,终端通过测量网络下发的定位参考信号获取定位信息。

具体实施方式
为了使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开作进一步地详细描述,显然,所描述的实施例仅仅是本公开一部份实施例,而不是全部的实施例。基于本公开中的实施例,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它实施例,都属于本公开保护的范围。
下面对文中出现的一些词语进行解释:
1、本公开实施例中术语“和/或”,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。字符“/”一般表示前后关联对象是一种“或”的关系。

5、本公开实施例中术语“测量间隔”指用于终端进行定位测量的资源。
6、本公开实施例中术语“同频”是指两个相邻小区中心频点一致。
本公开实施例描述的应用场景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,随着新应用场景的出现,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。其中,在本公开的描述中,除非另有说明,“多个”的含义是两个或两个以上。
基于位置的服务和应急呼叫定位驱动在无线网络中定位的发展。第三代合作伙伴长期演进中的定位支持在第9版中被引入。这使操作员能够检索用于基于位置的服务的位置信息,并且满足管制应急呼叫定位要求。全球定位系统使能的终端能够满足对定位的要求,但由于卫星信号在城区和室内环境中被阻塞,它们不能提供要求的可用性。因此,在此类环境中需要其它技术。
在LTE中可以通过观察到达时差的方法,OTDOA是终端辅助方法,终端估计来自不同基站的定位参考信号的到达时差,并且将这些参考信号时差测量被量化并且经由LPP(Lightweight Presentation Protocol,轻量级表示协议)与准确度评估一起报告给E-SMLC(Evolved Serving Mobile Location Centre,演进服务移动位置中心)。基于基站的已知位置和它们相互时间同步,E-SMLC使用多点定位从参考信号时差测量和协方差报告估计终端位置。准确度取决于接收到的信号的无线电条件、接收到的信号的数量、以及部署,这意味着它将在空间上不同。
然而,在OTDOA中,终端被要求检测多个相邻小区信号,但这些信号遭受差的可测性的影响。但是相关技术中的5G NR中还没有定位参考信号的设计,尚不支持终端辅助的定位技术,及相应的测量流程。
因此本公开实施例提供了用于定位测量的定位参考信号以及用于RRM测量的参考符号,借助终端进行定位测量。
针对上述场景,下面结合说明书附图对本公开实施例做进一步详细描述。
如图1所示,本公开实施例的一种定位测量的系统包括:终端100、网络侧设备101和定位节点102。
终端100,用于在接收到开启定位测量的消息后,向网络侧设备发送开启定位测量的指示信息;根据接收到的所述网络侧设备发送的RRC消息以及定位节点发送的定位辅助数据进行定位测量。
定位节点102,用于向网络侧设备101发送定位请求信息;根据接收到 的所述网络侧设备发送的包含SSB配置信息的定位响应信息,确定定位辅助数据;将所述定位辅助数据发送给终端,以使所述终端根据接收到的所述网络侧设备发送的RRC消息以及所述定位节点发送的定位辅助数据进行定位测量。
网络侧设备101,用于在接收到定位节点102发送的定位请求信息后,向所述定位节点发送包含RRM测量参考符号配置信息的定位响应信息;在接收到终端发送的开启定位测量的指示信息后向所述终端发送RRC消息,以使所述终端根据接收到的所述网络侧设备发送的RRC消息以及所述定位节点发送的定位辅助数据进行定位测量。
在本公开实施例中,定位节点与网络侧设备之间首先进行信息交互,由网络侧设备向定位节点发送包含SSB配置信息的定位响应信息;相应地,定位节点可以根据接收到的网络侧设备的定位响应信息为终端配置用于定位测量的测量间隔和/或BWP,并向终端发送定位辅助数据;在终端接收到高层发送的开始定位测量的指示信息后向网络侧设备发送开启定位测量的指示信息,指示网络侧设备为终端配置合适的测量间隔配置信息和/或BWP配置信息,由于本公开提供了一种定位参考信号以及终端辅助的测量流程,提供了一种由终端、网络侧设备及定位节点之间进行信息交互,可以应用于5G NR的基于终端来进行定位测量的方法。
在本公开实施例中,由定位节点向网络侧设备发送定位请求信息,其中,所述定位请求信息包括但不限于下列的部分或全部:
小区定位参考信号配置信息、SSB配置信息、用于辅助网络侧设备配置测量间隔的测量间隔配置信息、用于辅助网络侧设备配置BWP的BWP配置信息。
在本公开实施例中,网络侧设备在接收到定位节点的定位请求信息之后,根据所述定位请求信息向定位节点回复包含SSB配置信息的定位响应信息,其中,所述定位响应信息包括但不限于下列的部分或全部:
小区定位参考信号配置信息、SSB配置信息、用于辅助网络侧设备配置测量间隔的测量间隔配置信息、用于辅助网络侧设备配置BWP的BWP配置信息。
其中,所述小区定位参考信号配置信息包括但不限于下列的部分或全部:
PRS的中心频点、带宽。
其中,所述小区的SSB配置信息包括但不限于下列的部分或全部:
小区的SSB发送周期、SSB偏移、SSB持续时间、频域的发送位置、同步信号块测量时间配置SMTC周期、SMTC偏移、SMTC持续时间。
在本公开实施例中,定位节点与网络侧设备进行定位请求与定位响应的方式有很多种,下面列举几种:
方式一、定位节点向网络侧设备发送的定位请求信息中包含具体的配置数值。
具体地,定位节点向网络侧设备发送定位请求信息中包含具体的配置数值,网络侧设备回复定位响应信息时确认定位请求信息中的配置数值是否可用的,若可用,则可以直接回复之前接收到的定位请求信息中的具体的配置数值或是重新配置并通过定位响应信息回复给定位节点,若不可用,则网络侧设备重新配置并通过定位响应信息回复给定位节点。
例如,定位节点向网络侧设备发送的定位请求信息为:小区定位参考信号PRS带宽为10MHz、SSB发送周期为80ms、偏移值为20ms、持续时间为2ms,网络侧设备确定这些配置数值可用,将这些数值确认后通过定位响应信息回复给定位节点,或者是重新配置,例如网络侧设备重新配置后回复给定位节点的定位响应信息为:小区定位参考信号PRS带宽为10MHz、SMTC发送周期为60ms、偏移值为20ms、持续时间为2ms。
方式二、定位节点向网络侧设备发送的定位请求信息不包含具体的配置数值。
具体地,网络侧设备在接收到定位节点发送的定位请求信息只包含请求网络侧配置小区定位参考信号及SSB的配置请求信息但是不包含具体的小区定位参考信号以及SSB的配置数值,即仅包含小区ID及相应的配置请求消息,则根据接收到的定位请求信息配置之后回复给定位节点。
例如,定位节点向网络侧设备发送定位请求信息,其中定位请求信息包括小区定位参考信号PRS带宽、SSB发送周期、偏移值以及持续时间的配置请求信息,定位节点请求网络侧设备回复具体的配置信息,例如,定位节点 回复的定位响应信息为:小区定位参考信号PRS带宽为10MHz、SSB发送周期为60ms、偏移值为20ms、持续时间为2ms。
需要说明的是,本公开实施例中所列举的定位节点与网络侧设备进行定位请求与定位响应的方式只是举例说明,任何一种定位节点与网络侧设备进行定位请求与定位响应的方式都适用于本公开实施例。
在本公开实施例中,定位节点接收到网络侧设备发送的包含SSB配置信息的定位响应信息之后,根据接收到的定位响应信息确定定位辅助数据。
在本公开实施例中,所述定位辅助数据包括下列的部分或全部:
物理小区ID、定位参考信号配置信息、测量间隔配置信息、BWP配置信息。
其中,所述测量间隔配置信息包括但不限于下列的部分或全部:
用于定位测量的测量间隔周期、偏移值、用于定位测量的测量间隔长度、用于定位测量的测量间隔共享因子。
其中,所述BWP配置信息包括但不限于下列的部分或全部:
BWP的频域位置、带宽、BWP的标识符。
例如,定位节点接收到网络侧设备发送的包含SSB配置信息的定位响应信息为:小区定位参考信号PRS带宽为10MHz、SSB发送周期为60ms、偏移值为20ms、持续时间为2ms,定位节点根据接收到的定位响应信息确定定位辅助数据为:用于定位测量的测量间隔周期为10ms、用于定位测量的测量间隔长度为10ms。
在确定物理小区ID时的方式有很多种,下面列举几种:
方式一、定位节点可以选择同频小区中SSB和PRS时域发送位置不同,但是频域位置相同的小区让终端测量,这样可以保证终端在做RRM和定位测量的时候不冲突。
如图2所示,图中有3个同频小区,分别为小区1、小区2、小区3,这3个小区SSB和PRS时域发送位置不同,但是频域位置相同的,则可以选择这3个小区让终端进行测量,并将这3个小区ID通过定位辅助数据发送给终端。
方式二、定位节点可以选择SSB和PRS时域发送位置重叠、频域位置发 送不同的小区让终端测量。
可选地,可以根据SSB和PRS频域发送位置配置一个包含SSB和PRS频域发送位置的BWP,这样可以保证一个测量间隔可以同时执行RRM测量和定位测量。
如图3所示为小区1的SSB和PRS在频域的发送位置,图中黑色部分为当前激活BWP,其中当前激活BWP中有一部分带宽与SSB带宽重叠,部分带宽与PRS带宽重叠,当前激活BWP的带宽大于PRS的带宽,且小区1的SSB和PRS在时域发送位置相同,则在同一测量间隔可以同时执行RRM测量和定位测量,定位节点将小区1的ID通过定位辅助数据发送给终端。
方式三、定位节点可以选择异频小区中SSB和PRS时域发送位置不重叠的小区让终端测量,这样终端可能需要不同的测量间隔来执行RRM测量和定位测量,此时定位节点可以再给终端配置一个测量间隔用于执行定位测量。
如图4所示,图中的3个异频小区分别为小区1、小区2、小区3,这3个小区SSB和PRS时域发送位置都不重叠,则可以选择这3个小区让终端进行测量,并将这3个小区ID通过定位辅助数据发送给终端。可选地,终端需要不同的测量间隔来执行RRM测量和定位测量,其中MG1(Measurement Gap 1,第一测量间隔)表示用于RRM测量的第一测量间隔、MG2(Measurement Gap 2,第二测量间隔)表示用于定位测量的第二测量间隔。
需要说明的是,本公开实施例中所列举的确定物理小区ID的方式只是举例说明,任何一种可以确定物理小区ID的方式都适用于本公开实施例。
在本公开实施例中,终端在接收到高层发送的开启定位测量的消息后,向网络侧设备发送开启定位测量的指示信息。
例如,终端收到定位协议层发送的开启定位测量的消息后,向网络侧设备发送开启定位测量的指示信息,其中,开启定位测量的指示信息有很多种,下面列举几种。
指示信息一、开启需要测量间隔的定位测量。
若定位测量需要使用测量间隔,且网络侧设备此时没有为终端配置测量间隔,或者所配置的测量间隔是无效的,例如所配置的测量间隔无法执行定位测量或是不包含有效的定位测量参考信号,则终端指示网络侧设备“开启需 要测量间隔的定位测量”。
可选地,终端将用于辅助网络侧设备配置测量间隔的测量间隔配置信息置于所述开启定位测量的指示信息中。
其中,终端配置用于辅助网络侧设备配置测量间隔的测量间隔配置信息的方式有很多种,下面列举几种:
配置方式1、定位节点发送给终端的定位辅助数据中包括测量间隔配置信息,终端将接收到的定位辅助数据中的测量间隔配置信息发送给网络侧设备。
例如,终端接收到的定位辅助数据为:小区1定位参考信号带宽为10MHz、用于定位测量的测量间隔周期为10ms、用于定位测量的测量间隔长度为10ms,其中包含用于定位测量的测量间隔配置信息,则所述终端将定位辅助数据中的测量间隔配置信息发送给网络侧设备。
配置方式2、定位节点发送给终端的定位辅助数据中不包括测量间隔配置信息,终端根据接收到的定位辅助数据判断需要的测量间隔配置并发送给网络侧设备。
例如,终端接收到的定位辅助数据为:小区1定位参考信号PRS带宽为10MHz、PRS发送周期为10ms、BWP带宽为15MHz,其中不包含用于定位测量的测量间隔配置信息,则所述终端根据接收到的定位辅助数据确定需要的测量间隔配置,例如,终端根据接收到的小区1的PRS发送周期确定用于辅助网络侧设备配置测量间隔的配置信息为:用于定位测量的测量间隔周期为10ms、用于定位测量的测量间隔长度为10ms。
需要说明的是,本公开实施例中所列举的终端配置用于辅助网络侧设备配置测量间隔的测量间隔配置信息的方式只是举例说明,任何一种终端配置用于辅助网络侧设备配置测量间隔的测量间隔配置信息的方式都适用于本公开实施例。
指示信息二、开启需要切换BWP的定位测量。
若定位测量需要切换BWP,即当前的激活BWP中无法执行定位测量,例如当前激活BWP的带宽小于PRS的带宽,或者BWP所在的位置不包括PRS,则终端指示网络侧设备“开启需要切换BWP的定位测量”。
如图5A所示,图中黑色部分表示当前激活带宽所在位置,当前激活BWP下方的阴影部分表示PRS频域所在位置,由图可知当前激活带宽中无法执行定位测量,因为BWP所在的位置不包括PRS,所以需要终端指示网络侧设备“开启需要切换BWP的定位测量”。
如图5B所示,图中黑色部分表示当前激活带宽所在位置,阴影部分表示PRS频域所在位置,当前激活带宽所在位置包括PRS,并且当前激活BWP的带宽大于PRS的带宽,此时终端不需要指示网络侧设备“开启需要切换BWP的定位测量”,若终端需要网络侧设备重新配置BWP,而不使用当前激活带宽,则终端仍可以指示网络侧设备“开启需要切换BWP的定位测量”。
可选地,终端将用于辅助网络侧设备配置BWP的BWP配置信息置于所述开启定位测量的指示信息中。
例如,终端需要的BWP带宽为10KHz,BWP的中心频点为5KHz位置处,则终端将包含BWP带宽及中心频点的额配置信息置于所述开启定位测量的指示信息中,此外还可以将和当前激活BWP之间的差值作为偏移值offset置于所述开启定位测量的指示信息中。
