背景技术
新空口(New Radio,NR)定位中,下行到达时间差(Download Timing Difference of Arrival,DL-TDOA)、上行到达时间差(Upload Timing Difference of Arrival,UL-TDOA)和多往返行程时间(multi Round Trip Time,multi-RTT)等基于时间的定位方法,通常都需要网络设备或终端设备测量参考信号的发送或接收时间来确定位置。
以DL-TDOA定位方法为例,终端设备需要测量多个网络设备所发送的下行定位参考信号(Positioning Reference Signal,PRS)的到达时间与参考网络设备发送PRS的参考信号到达时间差(Reference Signal Time difference,RSTD),从而构建出多个双曲线方程求解出终端设备的位置坐标。
在理想情况下,RSTD可以反应不同网络设备与目标终端设备的距离差。但在实际测量过程中,由于硬件的处理时延可能导致时间测量误差,即,群时延误差。为了提高定位精度,可以将参考信号的测量结果划分为定时误差组(Timing Error Group,TEG),从而消除同组的测量结果之间的群时延误差。相关技术中,并未涉及如何对定时误差组进行划分。

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。
新空口(New Radio,NR)定位中,下行到达时间差(Download Timing Difference of Arrival,DL-TDOA)、上行到达时间差(Upload Timing Difference of Arrival,UL-TDOA)和多往返行程时间(multi Round Trip Time,multi-RTT)等基于时间的定位方法,通常都需要网络设备或终端设备测量参考信号的发送或接收时间来确定位置。
以DL-TDOA定位方法为例,终端设备需要测量多个网络设备所发送的下行定位参考信号(Positioning Reference Signal,PRS)的到达时间与参考网络设备发送PRS的参考信号到达时间差(Reference Signal Time difference,RSTD),从而构建出多个双曲线方程求 解出终端设备的位置坐标。
在理想情况下,RSTD可以反应不同网络设备与目标终端设备的距离差(通过传播时间差*光速确定)。但在实际测量过程中,由于硬件的处理时延可能导致时间测量误差,即,群时延误差。
示例性的,图1为本申请实施例提供的硬件的处理时延对定位的影响示意图,如图1所示,在测量参考信号的到达时刻时,理论上以信号到达天线的时间为准,RSTD测量的参考时间点位于天线连接器(FR1)或天线(FR2)。然而,参考信号的实际到达时刻却需要等参考信号从射频处理并传输基带的时刻。因此,由于硬件的处理时延,参考信号的实际发送时刻早于理想发送时刻,参考信号的实际到达时刻晚于理想到达时刻。相应的,参考信号的理想传播时延小于实际传播时延。
下面对于硬件的处理时延进行说明。
在本申请中,存在多种导致硬件的处理时延的因素。在一些情况下,导致硬件的处理时延的因素与收发硬件相关(例如,电缆长度等),其导致的时延误差是静态的。在一些情况下,导致硬件的处理时延的因素与信号或波束的配置相关(例如,射频链、频带、基带采样率等),其导致的时延误差是半静态的。在另一些情况下,导致硬件的处理时延的因素是完全动态的(例如,干扰和噪声等)。
其中,电缆传输时延,与电缆连接线的长度有关,相同的硬件配置下电缆传输时延是相对固定的。射频链路的电路时延,可以包括数模转换器(Digital to analog converter,DAC)、滤波器、混频器、放大器PA等,其收发时延可能不对称。针对天线阵列,如当采用宽/窄模拟波束(beam)收发时,动态的天线阵列相位中心可能会影响TOA/TOD的误差,且随着模拟波束的配置而变化。针对基带采样率和偏移,其与信号带宽有关,且随着收发信号配置的不同而变化。
应理解,上述导致硬件的处理时延的因素可以分为以下三种类型。
第一种类型可以为收发参考信号的硬件收发链路,例如天线、射频单元、放大器、锁相环等。若经过设备内部校准补偿后,不同的硬件接收链路误差足够小,则可以等效为同一个硬件收发链路。硬件接收链路是相对固定且易于区分的。硬件收发设备可以通过通信设备的能力体现。
第二种类型可以为参考信号的配置,例如带宽、频点、频带。参考信号配置比较灵活,但由于参考信号是网络设备配置给终端设备的,网络设备和终端设备对参考信号的配置都是已知的。
第三种类型可以为收发参考信号的方式,可能会涉及到实现行为。例如,波束的具体实现方式,是否做过采样等。只有一端设备已知收发参考信号的方式。示例性的,接收PRS的方式是否做过采样是终端设备实现决定的,网络设备未知。
为了提高定位精度,可以将参考信号的测量结果划分为定时误差组,从而消除同组的测量结果之间的群时延误差。定时误差组的作用是保证同一个组内的定时误差在一定范围内。虽然定时误差可能是随着时间动态变化的,但定时误差组是相对固定或者半静态的。相关技术中,并未涉及如何对定时误差组进行划分。
为解决上述问题,本申请实施例提供一种通信方法及装置,通过通信设备收发参考信号的能力,确定参考信号的测量结果的定时误差组,从而实现对定时误差组的划分,进而可以消除同组的测量结果之间的群时延误差,提高定位精度。
需要说明的是,本申请实施例的技术方案可以应用于全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division  Duplex,TDD)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。

应理解,本申请实施例对于参考信号的类型不做限制,在一些实施例中,参考信号包括定位参考信号(Positioning Reference Signal,PRS)和/或信道探测参考信号(Sounding Reference Signal,SRS),PRS用于下行定位测量,SRS用于上行定位测量。
需要说明的是,本申请实施例对于如何确定参考信号的测量结果的定时误差组不做限制,在一些实施例中,若第一信息与第二信息相同,则确定参考信号的测量结果属于定时 误差组,第二信息用于指示定时误差组对应的通信设备收发参考信号的能力。
下面对于第一信息中包含的反应通信设备收发参考信号的能力的信息进行说明。
在本申请实施例中,第一信息中包括以下至少一项:通信设备用于收发参考信号的硬件收发链路信息、参考信号的配置参数和收发参考信号的参数。

应理解,收发参考信号的参数包括以下至少一项:采样率、过采样倍数和模拟波束的实现方式。其中,模拟波束的实现方式可例如动态天线阵列的中心相位点。
在一些实施例中,通信设备需要指示收发参考信号所需的实现过程。示例性的,可以通过无线资源控制信令或媒体接入层控制单元发送采样率和过采样倍数,通过模拟波束的实现方式进行参考信号的收发操作。
应理解,上述硬件收发链路信息所属的通信设备可以为终端设备也可以为网络设备,本申请实施例对此不作限制。
在一些实施例中,硬件收发链路信息可以包括射频器件信息和/或基带器件信息。相应的,若参考信号和定时误差组对应的射频器件和基带器件相同,则该参考信号的测量结果属于该定时误差组。

在一些实施例中,通信设备的硬件收发链路信息与通信设备的能力有关,或者,可以通过通信设备的能力反应出来。相应的,硬件收发链路信息,包括以下至少一项:通信设备的波束管理类型、通信设备是否具备同时测量两个不同定位频率层的能力、通信设备是否支持参考信号传输的严格同步以及通信设备是否具备双功放。
示例性的,通信设备的波束管理类型包括IBM和CBM,若通信设备的波束管理类型为CBM,则表示通信设备会通过相同的波束来接收参考信号,则采用CBM的硬件收发链路信息相同。
示例性的,若通信设备不具备同时测量两个不同定位频率层的能力,则确定该通信设备只具备一个硬件收发链路信息。若通信设备具备同时测量两个不同定位频率层的能力,则确定该通信设备具备两个硬件收发链路信息。
示例性的,通信设备是否支持参考信号传输的严格同步可以通过通信设备是否支持ul-TimingAlignmentEUTRA-NR或singleUL-transmission能力来确定。
示例性的,若通信设备不具备双功放,参考信号在硬件收发链路信息中采用相同的功率器件。若通信设备具备双功放,参考信号在硬件收发链路信息中采用不同的功率器件
下面提供几种可能的定时误差组的确定方式。
在第一种方式中,定时误差组是根据硬件收发链路信息确定,相应的,若参考信号对应的硬件收发链路信息和定时误差组对应的硬件收发链路信息相同,则可以确定参考信号的测量结果属于该定时误差组。
在第二种方式中,定时误差组是根据硬件收发链路信息和参考信号的配置参数确定,若参考信号对应的硬件收发链路信息和定时误差组对应的硬件收发链路信息相同且参考信号的配置参数与定时误差组对应的配置参数相同,则可以确定参考信号的测量结果属于该定时误差组。
在第三种方式中,定时误差组是根据硬件收发链路信息、参考信号的配置参数和收发参考信号的参数确定,若参考信号对应的硬件收发链路信息和定时误差组对应的硬件收发链路信息相同、参考信号的配置参数与定时误差组对应的配置参数相同且收发参考信号的参数和定时误差组对应的定时误差组对应的相同,则可以确定参考信号的测量结果属于该定时误差组。
S202、消除定时误差组的同组的测量结果之间的群时延误差。
其中,参考信号的测量结果可以为参考信号到达时间差。
需要说明的是,若参考信号的测量结果属于同一组定时误差组,则可以认为测量结果的群时延误差相等,通过相减抵消测量结果的群时延误差相。
本申请实施例提供的通信方法,通过根据参考信号对应的第一信息,确定参考信号的测量结果的定时误差组。其中,定时误差组用于消除同组的测量结果之间的群时延误差,第一信息用于指示通信设备收发参考信号的能力。通过该方式,可以基于通信设备收发参考信号的能力对参考信号的测量结果进行分组,从而消除同组的测量结果之间的群时延误差,提高定位精度。
在上述实施例的基础上,下面对于定时误差组的误差参数(TEG margin)进行说明。定时误差组的误差参数与通信设备、频率范围、频带范围、频带组合范围或定时误差组对应。图4为本申请实施例提供的另一种通信方法的流程示意图。本申请实施例的执行主体为通信设备,涉及的是如何确定定时误差组的误差参数的过程。如图4所示,该方法包括:
S301、根据第一信息,确定参考信号的测量结果的定时误差组;其中,定时误差组用于消除同组的测量结果之间的群时延误差,第一信息用于指示通信设备收发参考信号的能力。
S302、确定定时误差组的误差参数。
应理解,定时误差组的误差参数与定时误差组的确定方式、误差参数的数量和误差参数的对应关系均存在关联。根据不同的通信设备收发参考信号的能力,可以设置不用的定时误差组的误差参数。
示例性的,采用CBM接收方式的定时误差组的误差参数比采用IBM的定时误差组的误差参数更小。
示例性的,不能同时接收两个定位频率层,则通信设备只有一个硬件收发链路信息,则定时误差组的误差参数更小。若能够同时接收两个定位频率层,则通信设备采用两套独立的硬件收发链路信息,则定时误差组的误差参数更大。
示例性的,若通信设备支持ul-TimingAlignmentEUTRA-NR或singleUL-transmission能力,则参考信号传输可以保持严格同步,定时误差组的误差参数较小。
示例性的,若通信设备不支持双功放能力,则参考信号传输都采用同样的功率放大器,定时误差组的误差参数较小。
下面对于定时误差组是根据硬件收发链路信息确定时,定时误差组的误差参数的确定方式进行说明。
在一些实施例中,若定时误差组是根据硬件收发链路信息确定且定时误差组的误差参数与通信设备、频率范围、频带范围、或频带组合范围对应,则定时误差组的误差参数为不同第一信息下的最大误差值。
在一些实施例中,若定时误差组是根据硬件收发链路信息确定且定时误差组的误差参数与定时误差组对应,则定时误差组的误差参数为定时误差组对应的硬件收发链路信息下的最大误差值。
在一些实施例中,若定时误差组是根据硬件收发链路信息确定且定时误差组的误差参数与通信设备对应,则定时误差组的每个误差参数分别为参考信号在不同配置参数下的最大误差值或不同的收发参考信号的参数下的最大误差值。
在一些实施例中,若定时误差组是根据硬件收发链路信息确定且定时误差组的误差参数与定时误差组对应,则定时误差组的每个误差参数分别为定时误差组对应的硬件收发链路信息在参考信号的不同配置参数下的最大误差值,或者,定时误差组的每个误差参数分别为定时误差组对应的硬件收发链路信息在不同的收发参考信号的参数下的最大误差值。
示例性的,若通信设备配置有两套不同的硬件收发链路信息(Rx chain1和Rx chain 2), 每条硬件收发链路信息在不同参考信号的带宽下的误差值如表1所示。
表1
  <=10MHz <=20MHz [N]MHz
Rx chain 1 X1*Tc X2*Tc
Rx chain 2 X3*Tc X4*Tc
若定时误差组分组只考虑硬件收发链路信息是否相同,则在确定定时误差组时,采用Rx chain 1接收参考信号的测量结果属于Rx TEG ID=1的定时误差组。采用Rx chain 2来接收参考信号的测量结果属于Rx TEG ID=2的定时误差组。参考表1,表1中的每一行就是一个定时误差组。在此基础上,定时误差组的误差参数是否还需要参考信号的配置参数等,可以细分为定时误差组的误差参数为唯一值和定时误差组的误差参数包括多个数值两种情况。
若定时误差组的误差参数为唯一值,则误差参数需要包含残留电缆传播时延、和处理参考信号等不同情况下的最大误差。
示例性的,若定时误差组的误差参数与通信设备、频率范围、频带范围、频带组合范围或定时误差组对应,则对应的通信设备、对应的频率范围、频带或频带组合范围内,定时误差组的误差参数的配置为max(X1,X2,X3,X4),所有的定时误差组均满足该误差参数。
示例性的,若定时误差组的误差参数与定时误差组对应,即,每个定时误差组存在一个误差参数。则Rx chain 1对应的定时误差组的误差参数是max(X1,X2),Rx chain 2对应的定时误差组的误差参数是max(X3,X4),通信设备需要分别上报每个定时误差组的误差参数。
在本申请中,定时误差组的误差参数为唯一值时,只需判断是否采用同样的硬件收发链路信息进行参考信号的收发即可完成分组,其实现较简单。
若每个定时误差组的误差参数包括多个数值,则误差参数的多个数值分别对应不同的参考信号配置。
示例性的,表2为一种误差参数的示意表。如表2所示,若定时误差组的误差参数与通信设备对应,当测量的参考信号带宽小于等于10MHz时,误差参数是max(X1,X3),而测量的参考信号带宽为10~20MHz时,误差参数是max(X2,X4)。所有的定时误差组均满足上述误差参数。可选的,通信设备可以将表2发送给网络设备或终端设备。
表2
参考信号带宽 <=10MHz <=20MHz
误差参数 Max(X1,X3)*Tc Max(X2,X4)*Tc
示例性的,表3为另一种误差参数的示意表。如表3所示,若定时误差组的误差参数与定时误差组对应,则参考信号带宽小于等于10MHz且采用Rx TEG 1测量时,误差参数是X1;参考信号带宽为10~20MHz且采用Rx TEG 2测量时,误差参数是X4。
表3
参考信号带宽 <=10MHz <=20MHz
TEG ID1误差参数 X1*Tc X2*Tc
TEG ID2误差参数 X3*Tc X4*Tc
在本申请中,定时误差组的误差参数包括多个数据值时,误差参数更加精确,有利于提高定位精度。
在一些实施例中,每个定时误差组的误差参数包括多个数值,且误差参数的多个数值分别对应不同的参考信号配置参数和收发参考信号的参数。则相应的,若定时误差组的误差参数与通信设备对应,当多个数值对应不同的采样率时,误差参数如表4所示,采样率1对应的误差参数为X5,采样率2对应的误差参数为X6。
表4
采样率 采样率1 采样率2
误差参数 X5*Tc X6*Tc
需要说明的是,收发参考信号的参数可以反应参考信号配置参数。
需要说明的是,若通信设备配置有多套不同的硬件收发链路信息,但通过校准后一部分硬件收发链路信息的时延误差较小,则可以将多套时延误差较小的硬件收发链路信息等效于一套硬件收发链路信息。
需要说明的是,上述参考信号的配置采用带宽,但并不限与此,还可以采用频点、频带、频带组合、子载波间隔等其他会影响定时精度的参考信号配置。
下面对于定时误差组是根据硬件收发链路信息和参考信号的配置参数确定时,定时误差组的误差参数的确定方式进行说明。
在一些实施例中,若定时误差组是根据硬件收发链路信息确定和参考信号的配置参数确定,则定时误差组的误差参数为硬件收发链路信息和参考信号的配置参数同时对应的误差值。
继续参考表1,不同带宽的参考信号会关联到不同的定时误差组,即上表中的每一格就是一个定时误差组。当采用Rx chain 1接收小于或等于10M带宽的参考信号时,则对应TEG ID 1的定时误差组;当采用Rx chain 1接收10M~20M带宽的参考信号时,则对应TEG ID 2的定时误差组;当采用Rx chain 2接收小于或等于10M带宽的参考信号时,则对应TEG ID 3的定时误差组;当采用Rx chain 2接收10M~20M带宽的参考信号时,则对应TEG ID4的定时误差组,依次类推。
示例性的,若定时误差组的误差参数与定时误差组对应,即,每个定时误差组对应有一个误差参数。TEG ID 1的定时误差组的误差参数是X1,TEG ID 2的定时误差组的误差参数是X2,TEG ID 3的定时误差组的误差参数是X3,TEG ID 4的定时误差组的误差参数是X4,依次类推。
下面对于定时误差组是根据硬件收发链路信息、参考信号的配置参数和收发参考信号的参数确定时,定时误差组的误差参数的确定方式进行说明。
在一些实施例中,若定时误差组是根据硬件收发链路信息确定、参考信号的配置参数确定和收发参考信号的参数确定,则定时误差组的误差参数为硬件收发链路信息、收发参考信号的参数和参考信号的配置参数同时对应的误差值。
应理解,通信设备需要上报实际的采样率或过采样倍数和波束的接收方式。其中,实际采样率为快速傅里叶变换(Fast Fourier Transform,FFT)大小、SCS和过采样倍数的乘积,波束的接收方式为沿用IBM或CBM。
可选的,定时误差组还可以采用多层分组的结构。定时误差组包括至少一个定时误差子组,定时误差组与硬件收发链路信息对应,定时误差子组与参考信号的配置参数或收发参考信号的参数对应。
示例性的,先根据是否采样相同的硬件接收链路确定不同的大组,例如Rx chain 1接收的对应TEG大组1,Rx chain 2接收的对应TEG大组2。随后,再根据是否实际的参考信号的配置参数和/或收发参考信号的参数划分大组内的小组。
应理解,若定时误差组的误差参数与通信设备对应,则定时误差组的误差Xb,和各个小组的误差{X1,X2,…},适用于所有定时误差组。
应理解,若定时误差组的误差参数与定时误差组(大组)对应,则每个定时误差组(大组)均关联各自的大组误差和多个小组误差。大组内的误差范围较大,小组内的误差范围较小。
本申请中,通过多层分组的结构,使定时误差组包括至少一个定时误差子组,从而使得定时误差组(大组)内不同定时误差子组(小组)的更多测量结果至少可以抵消掉一部 分传播时延等公共部分(对应较大的误差范围),从而使得定时误差组内同一个误差子组(小组)内的小部分测量结果只包含热噪声等较小的随机误差。多层分组可以同时保留上述两个方法的优点。
S303、将定时误差组的误差参数发送给网络设备或终端设备。
在本申请中,当通信设备确定定时误差组的误差参数后,可以将定时误差组的误差参数发送给网络设备或终端设备。当定位算法是由终端设备执行且通信设备为网络设备时,则网络设备可以将定时误差组的误差参数发送给终端设备。当定位算法是由网络端来执行且通信设备为终端设备时,则终端设备可以将定时误差组的误差参数发送给网络设备。
在上述实施例的基础上,由于硬件的固有偏差、通信设备的位置、环境等的变化,定时误差组具有一定的时效性。下面对于如何确定定时误差组的有效时间进行说明。图5为本申请实施例提供的再一种通信方法的流程示意图。本申请实施例的执行主体为通信设备,参考图5,该方法包括:
S401、根据第一信息,确定参考信号的测量结果的定时误差组。
其中,定时误差组用于消除同组的测量结果之间的群时延误差,第一信息用于指示通信设备收发参考信号的能力。
S402、确定参考信号的定时误差组的有效时间。
在本申请,当参考信号的测量结果在定时误差组的有效时间内,则可以保证定时误差组的误差参数有效。否则,定时误差组的误差参数无效。
应理解,本申请实施例对于如何确定定时误差组的有效时间不做限制,可以通过有效时间的起始时刻、有效时间的结束时刻和有效时间的时长确定。示例性的,有效时间为[Tstart,Tend],长度T=Tend–Tstart,则在[Tstart,Tend]内定时误差组的误差参数有效。
在一些实施例中,有效时间的起始时刻为第一预设时刻,或者,由第一个关联到定时误差组的测量结果触发的时刻,或者,由指示信令指示的时刻。
其中,第一预设时刻和第二预设时刻根据有效时间的时长和重启参考时间确定。指示信令承载于定位辅助信息或定位请求信息或者测量上报信息中。
示例性的,可以从第一预设时刻开始周期性重启Tstart=Tref+N*T。其中,Tref为上述第一时刻,可以为1900-01-01的协调世界时(Universal Time Coordinated,UTC)时间00:00:00,每T秒周期重启一次,重启的时间即为有效时间的起始时刻。
示例性的,可以由第一个关联到定时误差组的测量结果触发有效时间的起始时刻。在第一种情况中,测量结果触发的起始时刻可以为上报测量结果的时刻或者测量参考信号的时刻。在第二种情况中,上述测量结果可以为收到定位请求和辅助数据后的上报的第一个测量结果。
示例性的,可以由额外的指示信令指示有效时间的起始时刻,例如,通过1比特来指示有效时间的起始时刻,0代表开始,1代表结束,从而触发定时误差组的生效或重启。
示例性的,在上报测量结果和对应的TEG ID时,可以同时触发该TEG ID开始计时。若之前使用过该TEG ID,则以触发信令为界限,之前和之后的TEG组无法合并。
在一些实施例中,有效时间的结束时刻为第二预设时刻,或者,由指示信令指示的时刻,或者,根据有效时间的起始时刻和有效时间的时长确定。
示例性的,有效时间的结束时刻可以从第二预设时刻开始周期性重启,例如Tend=Tref+(N+1)*T。示例性的,可以通过额外的指示信令指示某个TEG ID开始失效,从而结束该TEG ID对应的定时误差组的有效时间。示例性的,还可以通过有效时间的时长和有效时间的开始时刻确定。
在一些实施例中,有效时间的时长为预设值,或者,由通信设备上报,或者,根据有效时间的起始时刻和有效时间的结束时刻确定。
在一些实施例中,有效时间的时长与目标定位精度关联,或者,与通信设备收发参考 信号的能力关联。示例性的,对于cm-level定位精度,有效时间长度T更短以避免硬件固有偏差对定位精度的影响(如晶振,目前规定终端设备的晶振偏差指标为0.1ppm,则1秒时间内最大定时偏移为0.1us)。
应理解,当有限时间长度T是终端设备上报时,T的取值可能与通终端设备的能力有关,终端设备可以根据其能力上报一个合适的时间T。
可选的,定时误差组的有效时间与通信设备对应,或者,定时误差组的有效时间与定时误差组对应。
图6为本申请实施例提供的一种定时误差组的有效时间示意图,如图6所示,有效时间[Tstart,Tend]根据Tend=Tref+(N+1)*T周期性重启。有效时间T1,将周期的开始时刻作为有效时间T1的起始时刻,将周期的结束时刻作为有效时间T1的结束时刻。将周期的开始时刻作为有效时间T2的起始时刻,当指示信令指示时效后,结束有效时间T2。当指示信令指示重启或者第一个关联到定时误差组的测量结果触发时,开启有效时间T3,将周期的结束时刻作为有效时间T3的结束时刻。
图7为本申请实施例提供的另一种定时误差组的有效时间示意图,如图7所示,当指示信令指示重启或者第一个关联到定时误差组的测量结果触发时,开启有效时间T4,当达到预设的有效时间的时长后,结束有效时间T4。
图8为本申请实施例提供的再一种定时误差组的有效时间示意图,如图8所示,当指示信令指示重启或者第一个关联到定时误差组的测量结果触发时,开启有效时间T5,当再次接收到指示信令后,结束有效时间T5,或者重启新的有效时间。
图9为本申请实施例提供的又一种定时误差组的有效时间示意图,如图9所示,若PRS1的测量结果的上报时间在PRS1的测量结果的定时误差组的有效时间内,则PRS1对应的定时误差组的误差参数有效。相应的,若PRS2的测量结果的上报时间在PRS2的测量结果的定时误差组的有效时间内,则PRS2对应的定时误差组的误差参数有效。
在本申请中,由于定时偏差可能是半静态甚至动态变换的,通过设置定时误差组的有效时间,可以防止定数误差随时间变化后定时误差组的误差参数无效的情况,进而提高了定位精度。
