Abstract
本公开涉及定位测量信息确定方法,包括:获取多个发送接收点之间的同步误差,根据所述同步误差确定定位测量信息。根据本公开,可以获取发送接收点之间的同步误差,进而根据同步误差确定定位测量信息,以消除定位测量信息中由于同步误差导致的偏差,例如在得到初始定位测量信息后,可以根据同步误差对初始定位测量信息进行调整,进而根据调整后的定位测量信息确定位置,有利于确保定位的准确性。
Description
本公开涉及通信技术领域,具体而言,涉及定位测量信息确定方法、同步误差发送方法、定位测量信息确定装置、同步误差发送装置、电子设备和计算机可读存储介质。
在5G通信中引入了多种定位技术,用于对终端进行定位,例如上行定位技术、下行定位技术、下行定位和上行定位相结合的定位技术。
针对下行定位而言,终端可以接收不同发送接收点(Transmission and Reception Point,简称TRP)发出的参考信号,并确定接收到每个参考信号的时间,进而根据该时间确定参考信号的到达时间差(Reference Signal Time Difference,简称RSTD),然后根据该到达时间差进行定位。
针对上行定位而言,不同的发送接收点可以接收终端发出的参考信号,并确定每个发送接收点接收到参考信号的时间,进而根据该时间确定参考信号的相对到达时间(Relative Time Of Arrival,简称RTOA),然后根据该相对到达时间进行定位。
可见,无论下行定位还是上行定位,都需要多个发送接收点之间协作,那么就需要多个发送接收点之间保持同步,否则会影响定位准确性。但是出于各种原因,不同发送接收点之间或多或少会存在一些同步误差,导致发送接收点之间不同步,进而影响定位准确性。

例如定位过程需要3个发送接收点TRP参与,分别为TRP1、TRP2和TRP3,那么确定的同步误差包括:TRP1和TPR2之间的同步误差error1,TRP1和TPR3之间的同步误差error2,TRP2和TPR3之间的同步误差error3。
在一个实施例中,同步误差产生的原因可以有多种,例如不同发送接收点之间的时钟不同步导致的同步误差,不同发送接收点之间硬件处理时间不同导致的同步误差。
在一个实施例中,第一设备和第二设备可以是相同的设备,也即第一设备可以自主确定同步误差。第一设备和第二设备也可以是不同的设备,例如第一设备为核心网,第二设备为终端,那么同步误差可以由终端确定,然后终端将确定的同步误差发送至核心网;例如第一设备为核心网,第二设备为基站,例如多个发送接收点所在的基站,那么同步误差可以由基站确定,然后基站将确定的同步误差发送至核心网。
在一个实施例中,通过确定发送接收点之间的同步误差,并将确定的同步误差发送至第一设备,使得第一设备可以根据同步误差确定定位测量信息,以消除定位测量信息中由于同步误差导致的偏差,例如在得到初始定位测量信息后,可以根据同步误差对初始定位测量信息进行调整,进而根据调整后的定位测量信息确定位置,有利于确保定位的准确性。
在一个实施例中,所述第二设备为核心网,所述第一设备为终端,所述将所述同步误差发送至第一设备包括:
向所述终端发送定位辅助信息和/或请求位置信息,其中,所述定位辅助信息和/或请求位置信息携带有所述同步误差。
在一个实施例中,在核心网向终端发送同步误差的情况下,核心网可以在定位过程中向终端发送信息时,将同步误差发送至终端。
例如核心网可以向终端发送定位辅助信息LPP Provide Assistance Data,那么核心网可以将同步误差携带在定位辅助信息中发送至终端。
例如核心网可以向终端发送请求位置信息LPP Request Location Information,那么核心网可以将同步误差携带在请求位置信息中发送至终端。
在一个实施例中,所述第二设备为基站,所述第一设备为终端,所述将所述同步误差发送至第一设备包括:
向所述终端发送定位系统信息和/或无线资源控制信息,其中,所述定位系统信息和/或无线资源控制信息中携带有所述同步误差。
在一个实施例中,在基站向终端发送同步误差的情况下,基站可以将同步误差 携带着在定位系统信息中发送至终端。其中,所述定位系统信息可以由基站广播,定位系统信息中除了携带同步误差,还可以携带定位辅助信息。
在一个实施例中,在基站向终端发送同步误差的情况下,基站可以将同步误差携带着在无线资源控制RRC信息中发送至终端。
在一个实施例中,第二设备为基站,第一设备为核心网,同步误差可以由基站发送至核心网,例如基站将同步误差携带在NRPPa(NR定位协议A)消息中发送至核心网。其中,同步误差可以由基站确定,由基站发送至核心网。
在一个实施例中,第二设备为终端,第一设备为核心网,同步误差可以由终端发送至核心网,例如终端将同步误差携带在定位信息LPP Provide Location Information发送至核心网。其中,同步误差可以由基站确定,基站先将同步误差发送至终端,再由终端发送至核心网。
以下主要针对多个发送接收点中的第一发送接收点TRP1和第二发送接收点TRP2,示例性描述确定同步误差的几种方式。
图7是根据本公开的实施例示出的另一种同步误差发送方法的示意流程图。如图7所示,在一些实施例中,所述多个发送接收点至少包括第一发送接收点和第二发送接收点,所述确定多个发送接收点之间的同步误差包括:
在步骤S701中,确定第一发送接收点与终端之间的第一往返时延和第二发送接收点与第二终端之间的第二往返时延(Round-Trip Time,简称RTT);
在步骤S702中,获取所述终端接收到所述第一发送接收点的定位参考信号和接收到所述第二发送接收点的定位参考信号的时间差;
在步骤S703中,根据所述时间差、所述第一往返时延和所述第二往返时延,确定所述第一发送接收点和所述第二发送接收点之间的同步误差。
在一个实施例中,可以先确定第一发送接收点与终端之间的第一往返时延RTT1和第二发送接收点与第二终端之间的第二往返时延RTT2。
其中,针对不同发送接收点而言,确定其与终端之间往返时延的方式可以是相同的。以第一发送接收点TPR1为例,TRP1向终端发送下行参考信号,终端在接收到下行参考信号后,向TRP1发送上行参考信号,TRP1发送下行参考信号的时刻为t1,终端接收到下行参考信号的时刻为t2,发送上行参考信号的时刻为t3,TRP1接收到 下行参考信号的时刻为t4。
t2到t3的时长t3-t2可以理解为终端内部处理时长,t1到t4的时长t4-t1包含了下行信号从TRP1到终端的传输时长,终端内部处理时长,以及上行参考信号从终端到TRP1的传输时长,那么在t4-t1的基础上减去t3-t2,剩余的就是下行信号从TRP1到终端的传输时长,以及上行参考信号从终端到TRP1的传输时长,也就是第一往返时长RTT1。可以采用类似的方式计算RTT2。
需要说明的是,上述根据参考信号的收发时间计算往返时延的方式,只是一种示例,还可以选择其他方式计算往返时延。
另一方面,还可以确定终端接收到第一发送接收点的定位参考信号和接收到第二发送接收点的定位参考信号的时间差RSTD。进而可以根据RSTD、RTT1和RTT2计算同步误差=RSTD-1/2*(RTT1-RTT2)。
在一些实施例中,所述多个发送接收点至少包括第一发送接收点和第二发送接收点,所述确定多个发送接收点之间的同步误差包括:
根据所述第一发送接收点的固有参数信息和所述第二发送接收点的固有参数信息,确定所述第一发送接收点和所述第二发送接收点之间的同步误差。
在一个实施例中,在发送接收点中可以预先存储有关自身特定的固有参数信息,例如时钟、硬件处理时间等,发送接收点所在的基站可以根据发送接收点之间固有参数信息的差异来确定发送接收点之间的同步误差,发送接收点也可以将固有参数信息发送至核心网,由核心网根据发送接收点之间固有参数信息的差异来确定发送接收点之间的同步误差。
例如针对任意两个不同的发送接收点,第一发送接收点和第二发送接收点,两个发送接收点的时钟相同,但是硬件处理时间不同,第一发送接收点的硬件处理时间为T1,第二发送接收点的硬件处理时间为T2,T1大于T2,那么第一发送接收点和第二发送接收点之间的同步误差可以等于T1-T2。
需要说明的是,以上实施例中的第一发送接收点和第二发送接收点,并非特指某个发送接收点,而是指在定位过程中使用的多个发送接收点中任意不同的两个发送接收点。

步骤S806,基站向终端发送定位测量间隙配置;
步骤S807,终端在该配置中基站测量定位参考信号,以得到初始定位测量信息例如RSTD或者位置信息,然后通过同步误差对初始定位测量信息进行调整;
步骤S808,终端将调整后的定位测量信息发送至核心网。
图9是根据本公开的实施例示出的另一种确定位置信息的示意流程图。如图9所示,以上行定位为例,确定位置信息的过程可以包括以下步骤:
步骤S901,核心网向终端发送能力请求信息LPP Request Capabilities;
步骤S902,终端向核心网发送能力信息LPP Provide Capabilities;
步骤S903,核心网向基站发送定位信息请求NRPPa Positioning Information Request;
步骤S904,基站确定探测参考信号(Sounding Reference Signal,简称SRS)的配置发送给终端;
步骤S905,基站向核心网发送定位信息响应NRPPa Positioning Information Response;
步骤S906,核心网向基站发送终端探测参考信号激活请求NRPPa Request UE SRS activation;
步骤S907,基站在激活终端发送探测参考信号后,向核心网发送终端探测参考信号激活响应NRPPa UE SRS activation Response;
步骤S908,核心网向基站发送测量请求NRPPa Measurement Request;
步骤S909,基站(具体可以是基站中的发送接收点)对终端发送的探测参考信号进行测量,以得到初始定位测量信息,例如RTOA或者位置信息,然后通过同步误差对初始定位测量信息进行调整;
步骤S910,基站将调整后的定位测量信息发送至核心网或者基站将测量信息和同步误差发送至核心网。
