  • Timing advance (TA)
  • the base station In order to ensure the orthogonality of uplink transmission and avoid intra-cell interference, the base station (e.g. eNodeB) requires signals from different terminal devices in the same subframe but with different frequency domain resources to arrive at the base station at the same time. That is, the base station requires uplink time synchronization. As long as the base station receives the uplink data sent by the terminal device within the cyclic prefix (CP) range, it can decode the uplink data correctly. Therefore, uplink time synchronization requires signals from different terminal devices in the same subframe to arrive at the base station within the CP. In order to ensure the uplink time synchronization on the base station side, LTE proposes an uplink timing advance (TA) mechanism.

Description

获取时间提前量的方法与装置
本申请要求于2019年04月30日提交中国专利局、申请号为201910361638.0、申请名称为“获取时间提前量的方法与装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，具体地涉及一种获取时间提前量(timing advance，TA)的方法与装置。
背景技术
当前，一种新型的为终端设备定位的方法被提出，即根据终端设备到多个基站的距离以及该多个基站的地理位置，对该终端设备进行定位。在这种定位方法中，需要知道终端设备到各个基站的距离。
根据电磁波的传输特点，终端设备到基站的距离等于电磁波在终端设备与基站之间传输的时间乘以光速。现有技术中存在时间提前量(timing advance，TA)的机制。TA表示一段时长，这个时长大约等于电磁波在终端设备与基站之间往返一次的时间。因此，可以利用终端设备到基站的TA，计算该终端设备到该基站的距离，等于1/2*TA*光速。
在上述定位方法中，参与终端设备定位的基站可能是终端设备所在的服务小区(Serving cell)中的基站，即服务基站，也可能终端设备的邻小区(neighbor cell)中的基站，即邻区基站，也可能既包括服务基站也包括邻区基站。因此，为了实现上述终端设备的定位，既需要知道终端设备到服务基站的TA，也需要知道终端设备到邻区基站的TA。
目前现有技术，中只有获取终端设备到服务基站的TA的方案，尚无获取终端设备到邻区基站的TA的方案。
因此，为了实现上述终端设备的定位，有必要提出一种可以获取终端设备到邻区基站的TA的方案。
发明内容
本申请提供一种获取时间提前量(TA)的方法与装置，可以获取终端设备到邻小区的TA。
第一方面，提供一种获取时间提前量TA的方法，该方法包括：终端设备接收第一小区广播的第一授时信息，接收邻小区广播的第二授时信息；根据下列信息获取终端设备到邻小区的TA：第一授时信息所指示的时间、终端设备到第一小区的TA、接收第一授时信息与第二授时信息之间的时间差、以及第二授时信息所指示的时间。
第一授时信息为第一小区广播的用于授时的时间信息。第二授时信息为邻小区广播的用于授时的时间信息。
第一小区为终端设备的服务小区，或者为终端设备预先已获知TA的某个邻小区。总之，第一小区表示终端设备能够获知TA，或者，已经预先知道TA的小区。
作为示例，获取终端设备到邻小区的TA的过程包括：1)根据终端设备到第一小区的TA，以及第一授时信息所指示的时间，获取接收到第一授时信息的绝对时间；2)由接收到第一授时信息的绝对时间，以及接收第一授时信息与第二授时信息之间的时间差，推算出接收到第二授时信息的绝对时间；3)由接收到第二授时信息的绝对时间，以及第二授时信息所指示的时间，推算出终端设备到邻小区的TA。
在本申请提供的方案中，通过接收第一小区与邻小区的授时信息，可以根据终端设备到第一小区的TA，以及所接收的授时信息，推算得到终端设备到邻小区的TA。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
除非另有定义，本申请使用的所有技术和科学术语与属于本申请技术领域的技术人员通常理解的含义相同说明书中使用的术语只是为了描述具体的实施例，不旨在于限制本申请。
图1为本申请实施例的应用场景的示意图。如图1所示，描述了一种定位原理，即通过终端设备到多个基站(图1示意性地示出3个基站)的距离以及各个基站的地理位置，对终端设备进行定位。
在图1所示的定位方案中，参与终端设备定位的多个基站(至少是3个基站)可以均为服务基站，也可以均为邻区基站，还可以既包括服务基站也包括邻区基站。例如，参与终端设备定位的基站包括一个服务基站和两个邻区基站。
前文已述，可以利用终端设备到基站的TA来获取终端设备到基站之间的距离，即等于1/2*TA*光速。按照这个思路，实现图1所示的定位方案，可能需要获取终端设备到服务基站的TA，也可能需要获取终端设备到邻区基站的TA。
但是，当前技术中只提供了获取终端设备到服务基站的TA的方案，尚无获取终端设备到邻区基站的TA的方案。
针对上述问题，本申请提出一种可以获取终端设备到邻区基站的TA的方案，从而可以实现图1所示的终端设备定位方案，或者可以满足其它需要获取终端设备到邻区基站的TA的应用场景的需求。
本申请实施例提供的技术方案可以应用于各种通信系统，例如，长期演进(long term evolution，LTE)系统、第五代移动通信(the 5th Generation，5G)系统、新空口(new radio，NR)系统、机器与机器通信(machine to machine，M2M)系统、或者未来演进的其它通信系统等。
图2和图3是本申请涉及的通信系统的示意性架构图。
如图2所示，本申请涉及的通信系统可以包括终端设备(图2中表示为UE)、无线 接入网(NG-RAN)和核心网。
核心网包括接入和移动性管理功能(access and mobility management function，AMF)与定位管理功能(location management function，LMF)等。AMF实现网关等功能，LMF实现定位中心等功能，AMF与LMF之间通过NLs接口连接。
无线接入网(NG-RAN)包括一个或多个ng-eNB和gNB。ng-eNB表示接入5G核心网的LTE基站，gNB表示接入5G核心网的5G基站。
ng-eNB与gNB之间、或两个ng-eNB之间，或两个gNB之间通过Xn接口通信。Xn接口还可称为XnAP接口。
无线接入网通过NG-C接口经由AMF连接到核心网。
终端设备通过LTE-Uu接口经由ng-eNB连接到无线接入网。终端设备还可通过NR-Uu接口经由gNB连接到无线接入网。
核心网可以通过LPP/NPP协议与终端设备通信。
应理解，该通信系统中可以包括一个或多个基站(ng-eNB和/或gNB)。
还应理解，该通信系统中可以包括一个或多个终端设备，例如包括一个或多个终端设备组(如图2中所示的UE set)。
一个gNB可以向一个或多个终端设备发送数据或控制信令。多个gNB也可以同时为一个终端设备发送数据或控制信令。
图2中的ng-eNB也可以替换为传输节点(transmission point，TP)(如图2中所示的TP)。
如图3所示，本申请涉及的通信系统可以包括终端设备(图3中表示为UE)、无线接入网(NG-RAN)和核心网。
核心网包括AMF与LMF等功能。AMF实现网关等功能，LMF实现定位中心等功能，AMF与LMF之间通过NLs接口连接。
无线接入网(NG-RAN)包括一个或多个ng-eNB和gNB。ng-eNB表示接入5G核心网的LTE基站，gNB表示接入5G核心网的5G基站。
其中，gNB包含定位管理组件(location management component，LMC)，LMC可以承担一部分LMF的功能。这样，如果要实现LMC可以承担的这部分LMF功能，不需要无线接入网经由AMF引入5G核心网，从而可以降低信令时延。
应理解，该通信架构中可以包括一个或多个基站(包括ng-eNB与gNB)。
还应理解，该通信架构中可以包括一个或多个终端设备，例如包括一个或多个终端设备组(如图3中所示的UE set)
一个gNB可以向一个或多个终端设备发送数据或控制信令。多个gNB也可以同时为一个终端设备发送数据或控制信令。
本申请实施例中涉及的终端设备可以指用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的 终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等。
本申请实施例中涉及的网络设备可以用于与一个或多个终端设备进行通信，也可以用于与一个或多个具有部分终端功能的基站进行通信(比如宏基站与微基站，如接入点，之间的通信)。基站可以是LTE系统中的演进型基站(evolved Node B，eNB)，或者5G系统、NR系统中的基站(gNB)。另外，基站也可以为接入点(access point，AP)、传输节点(transport point，TRP)、中心单元(central unit，CU)或其它网络实体，并且可以包括以上网络实体功能中的部分或所有功能。例如，本申请实施例中涉及的网络设备可以对应于图2和图3所示通信架构中的接入网设备。
本申请实施例中涉及的定位管理设备表示具有定位管理功能的核心网设备，例如，图2中所示的LMF，或者，定位管理设备表示具有定位管理功能的可置于接入网设备中的装置，例如，图3中所示的LMC。
还需要说明的是，在本申请中，“小区”与“小区中的基站”这两种描述是等效的。即，本申请中提及的小区表示该小区中的基站，本申请中提及的基站也表示该基站所在的小区。例如，本申请中提及的服务小区(serving cell)也可表示服务小区中的基站，即服务基站。本申请中提及的邻小区(neighbor cell)也可表示邻小区中的基站，即邻区基站。
为了更好地理解本申请提供的方案，首先介绍本申请实施例涉及到的术语。
1、时间提前量(timing advance，TA)
为了保证上行传输的正交性，避免小区内(intra-cell)干扰，基站(例如eNodeB)要求来自同一子帧但不同频域资源的不同终端设备的信号到达基站的时间基本上是对齐的，即基站要求上行时间同步。基站只要在循环前缀(cyclic prefix，CP)范围内接收到终端设备发送的上行数据，就能够正确地解码上行数据。因此，上行时间同步要求来自同一子帧的不同终端设备的信号到达基站的时间都落在CP之内。为了保证基站侧的上行时间同步，LTE提出了上行时间提前量(timing advance，TA)的机制。TA表征的是一段时长，大约为电磁波在终端设备与基站之间传输的往返时间。多个终端设备按照各自到同一个基站的TA，向该基站发送上行数据，可以实现，来自这多个终端设备的信号到达该基站的时间基本上对齐。
现有技术中，TA机制是适用于终端设备与其服务基站的。
终端设备到服务小区的TA可以通过终端设备向服务小区发送前导码，服务小区根据接收到的前导码计算得到。服务小区将终端设备到服务小区的TA配置到终端设备上，使得终端设备根据该TA进行上行发送。
2、广播授时
广播授时是通过终端设备读取服务小区广播的系统信息中的时间信息，结合终端设备到服务小区的TA，来确定当前时间的一种授时方式，基本原理如图4所示。
服务小区在特定帧(如图4中的SFN0)周期性广播时间相关的系统信息，该系统信息中包括一个时间值(如图4中所示的时间：1:00:00:000)，该时间值可以关联到该特定帧的边界。终端设备接收到系统信息后，解析出这个时间值，在该时间值所表示的时间上增加1/2*TA，即得到该时间值关联的帧边界的绝对时间。其中，TA为终端设备到服务小区的时间提前量。
图5为本申请实施例的获取时间提前量TA的方法500的示意性流程图。该方法500可以由终端设备执行，或者，也可以由配置于终端设备中的芯片或电路等器件执行。该方法500包括如下步骤。
S510、接收第一小区广播的第一授时信息，接收邻小区广播的第二授时信息。
第一授时信息为第一小区广播的用于授时的时间信息。第二授时信息为邻小区广播的用于授时的时间信息。
例如，第一授时信息或第二授时信息表示一个时间值，如图4中所示的时间1:00:00:000。
作为示例，终端设备接收第一授时信息的方式可以包括：终端设备接收第一小区广播的系统信息，从中解析得到该第一授时信息。终端设备接收第二授时信息的方式可以包括：终端设备接收邻小区广播的系统信息，从中解析得到该第二授时信息。
本申请对接收第一授时信息与第二授时信息的先后顺序没有限制。
本申请实施例中涉及的第一小区，可以为终端设备的服务小区，或者，还可以为终端设备预先已获知TA的某个邻小区。总之，第一小区表示终端设备能够获知TA，或者，已经预先知道TA的小区。
本申请实施例中涉及的邻小区表示待确定其与终端设备之间的TA的邻小区。
S520、根据下列信息获取终端设备到邻小区的TA：第一授时信息所指示的时间、该终端设备到第一小区的TA、接收第一授时信息与第二授时信息之间的时间差、以及第二授时信息所指示的时间。
获取终端设备到邻小区的TA的过程可以包括：1)根据该终端设备到第一小区的TA，以及第一授时信息所指示的时间，获取接收到第一授时信息的绝对时间；2)由接收到第一授时信息的绝对时间，以及接收第一授时信息与第二授时信息之间的时间差，推算出接收到第二授时信息的绝对时间；3)由接收到第二授时信息的绝对时间，以及第二授时信息所指示的时间，推算出终端设备到邻小区的TA。
图6为上述获取终端设备到邻小区的TA的过程的一个示例。在图6中，假设第一小区为服务小区。终端设备接收服务小区广播的第一授时信息，并读取第一时间(如图6中所示的时间1：1:00:00:000)，接收邻小区广播的第二授时信息，并读取第二时间(如图6中所示的时间2：1:00:00:0023)。终端设备通过第一时间，以及终端设备到服务小区的时间提前量(如图6中所示的TA1)，获得绝对时间1(如图6中所示的绝对时间1＝时间1+TA1/2)。理论上，通过第二时间，以及终端设备到邻小区的时间提前量(如图6中所示的TA2)，也可以获得一个绝对时间(记为绝对时间2)(如图6中所示的绝对时间2＝时间2+TA2/2)。
因为，绝对时间是恒定的，所以，可以根据如下公式计算得到终端设备到邻小区的时间提前量TA2：
T1‘+△t＝T2’＝T2+1/2*TA2，
其中，T1‘表示绝对时间1，△t表示终端设备接收第一授时信息与第二授时信息之间的时间差，T2’表示绝对时间2，T2表示第二时间。
本申请通过接收第一小区与邻小区的授时信息，可以根据终端设备到第一小区的TA，以及所接收的授时信息，推算得到终端设备到邻小区的TA。
在图1所示的定位场景中，如果参与定位的基站包括邻区基站，应用本申请提供的方案，可以获知终端设备到邻区基站的TA，从而可以获知终端设备到邻区基站的距离，进而可以实现终端设备的定位。
此外，本申请在无需引入新的物理量的前提下，可以较为简便地推算出终端设备到邻小区的TA，是一种适用范围较广的方案。
在步骤S510中，终端设备根据第一小区的授时配置信息接收第一小区广播的第一授时信息，根据邻小区的授时配置信息接收该邻小区广播的第二授时信息。
其中，一个小区的授时配置信息用于指示该小区广播授时信息的时频资源。即终端设备在授时配置信息指示的时频资源上，接收小区广播的授时信息。
对于服务小区的授时配置信息，终端设备应该是已知的。例如，在接入服务小区的过程中会接收到服务小区配置的授时配置信息。
对于邻小区的授时配置信息，由服务基站或定位管理设备向终端设备下发。
在服务基站中不包括可以承担定位管理功能的组件的情况下(例如，服务基站为图2中所示的gNB)，可以由核心网的定位管理设备(如图2中所示的LMF)搜集邻小区的授时配置信息，并向终端设备发送邻小区的授时配置信息。
在服务基站中包括可以承担定位管理功能的组件的情况下(例如，服务基站为图3中所示的gNB)，可以由服务基站搜集邻小区的授时配置信息，并向终端设备发送邻小区的授时配置信息。
应理解，在服务基站中包括可以承担定位管理功能的组件的情况下，也可以由核心网的定位管理设备搜集邻小区的授时配置信息，并向终端设备发送邻小区的授时配置信息。
需要说明的是，在网络侧(服务基站或定位管理设备)向终端设备发送多个邻小区的授时配置信息的情况下，在发送各个邻小区的授时配置信息的同时还应发送相应小区的小区标识(小区ID)。
可选地，在一些实施例中，上述方法500还包括：从服务小区或定位管理设备接收定位辅助信息，该定位辅助信息中包括邻小区的授时配置信息。
例如，该定位辅助信息中包括多个邻小区的授时配置信息以及相应邻小区的小区ID。
在上述涉及授时配置信息的实施例中，一个小区的授时配置信息用于指示该小区广播授时信息所使用的时频资源。
例如，一个小区的授时配置信息包括时域资源配置信息和频域资源配置信息。
作为示例，一个小区的授时配置信息中包括下列信息中的任一项或多项：广播周期、广播窗口位置、频域资源位置等。
应理解，终端设备从网络侧接收到邻小区的授时配置信息之后，可以将其缓存在本地，在后续接收该邻小区广播的授时信息的过程中，可以重复使用。即终端设备无需在每次接收邻小区广播的授时信息之前均要从网络侧接收该邻小区的授时配置信息。
可选地，在一些实施例中，终端设备在接收到邻小区的授时配置信息之后，如果当前服务小区为终端设备配置的测量间隔(测量GAP)不能覆盖该邻小区的授时配置信息指示的时域位置，该方法500还包括：终端设备向服务小区发送测量间隔请求消息，用于请求覆盖邻小区广播授时信息的时域位置的测量间隔；从服务小区接收测量间隔配置信息，测量间隔配置信息指示的测量间隔覆盖邻小区广播授时信息的时域位置。其中，步骤S510 包括：终端设备在测量间隔配置信息指示的测量间隔期间，接收邻小区广播的第二授时信息。
例如，测量间隔请求消息中携带指示邻小区的授时信息的时域位置的信息。
测量间隔请求消息中还可以携带邻小区的小区ID。
再例如，测量间隔请求消息中可以携带多个邻小区的授时信息的时域位置的信息以及各个邻小区的小区ID。
还应理解，终端设备在接收到邻小区的授时配置信息之后，如果当前服务小区为终端设备配置的测量间隔可以覆盖该邻小区的授时配置信息指示的时域位置，终端设备可以基于当前的测量间隔，直接接收邻小区广播的授时信息。
还应理解，如果邻小区与服务小区在同一频点，终端设备无需利用测量间隔来接收邻小区广播的授时信息，这种情况下，也无需请求服务基站配置测量间隔。
作为示例，图7示出本申请实施例的获取时间提前量TA的方法700的示意性交互图。该方法700包括如下步骤。
S710、定位管理设备收集一个或多个邻小区(图7中示出一个邻小区)的授时配置信息。
例如，定位管理设备可以从参与终端设备定位的邻小区(即邻区基站)，搜集授时配置信息。
S720、定位管理设备向终端设备发送定位辅助信息，该定位辅助信息中包括在步骤S710中获取的邻小区的授时配置信息以及对应的小区ID。
终端设备接收到定位辅助信息后，可以获知一个或多个邻小区广播授时信息的时域位置和频域位置。
S730、如果终端设备当前的测量间隔不能覆盖一个或多个邻小区的授时信息的时域位置，即当前的测量间隔无法满足对一个或多个邻小区的授时信息的读取，则终端设备向服务小区发送测量间隔请求消息，该测量间隔请求消息中包括一个或多个邻小区的授时配置信息以及相应的小区ID。
例如，该测量间隔请求消息中还可以包括各邻小区的小区频率信息等。
S740、服务基站基于测量间隔请求消息，向终端设备发送测量间隔配置信息，该测量间隔配置信息指示的测量间隔能够覆盖该测量间隔请求消息中携带的一个或多个邻小区的授时信息的时域位置。
S750、终端设备计算终端设备到各个邻小区的TA。
步骤S750可以通过前文描述的步骤S510和步骤S520来实现，其中，第一小区为服务小区。具体详见上文，这里不再赘述。
S760、终端设备向定位管理设备上报步骤S750得到的终端设备到邻小区的TA。
应理解，定位管理设备根据终端设备到邻小区的TA可以计算出终端设备到邻小区的距离，进而基于邻基站的地理位置，可以获得终端设备的定位。
可选地，在一些实施例中，步骤S730和步骤S740可以不执行。
可选地，在一些实施例中，服务基站(即服务小区)包括具备定位管理功能的部件，例如该部件为图3中所示的gNB，则步骤S710和步骤S720均由服务小区执行。
基于上述描述，本申请提供的方案，通过接收第一小区与邻小区的授时信息，可以根 据终端设备到第一小区的TA，以及所接收的授时信息，推算得到终端设备到邻小区的TA。
在图1所示的定位场景中，如果参与定位的基站包括邻区基站，应用本申请提供的方案，可以获知终端设备到邻区基站的TA，从而可以获知终端设备到邻区基站的距离，进而可以实现终端设备的定位。
此外，本申请在无需引入新的物理量的前提下，可以较为简便地推算出终端设备到邻小区的TA，是一种适用范围较广的方案。
上文描述了基于广播授时来获取终端设备到邻小区的TA的方案。除此之外，本申请还提供另一种方案来获取终端设备到邻小区的TA。
图8为本申请另一实施例的获取时间提前量TA的方法800的示意性交互图。如图8所示，该方法800包括如下步骤。
S810、服务小区为终端设备配置前导码(preamble)配置信息，该前导码配置信息指示终端设备发送前导码的时频资源。
例如，该前导码配置信息中可以包括用于发送前导码的时域资源配置信息和频域资源配置信息。
再例如，该前导码配置信息所指示的终端设备发送前导码的时频资源可以是随机接入资源。
可选地，该前导码配置信息中还可以包括前导码的序列信息。
应理解，如果网络侧与终端设备约定好了前导码的序列信息，则该前导码配置信息中可以不携带前导码的序列信息。
例如，服务小区可以通过无线资源控制(radio resource control，RRC)信令向终端设备发送前导码配置信息。
可选地，该前导码配置信息所指示的前导码可以是专用前导码。
可选地，在步骤S810之前，还可以包括：定位管理设备指示服务小区，需要进行终端设备到邻小区的TA的计算。
S820、服务小区向定位管理设备发送在步骤S810中为终端设备分配的前导码配置信息，定位管理设备将该前导码配置信息发送给邻小区。
定位管理设备可以向一个或多个邻小区发送该前导码配置信息。
例如，定位管理设备可以向参与终端设备定位的邻小区发送该前导码配置信息。
S830、终端设备根据该前导码配置信息发送前导码，邻小区根据该前导码配置信息接收终端设备发送的前导码。
需要说明的是，邻小区在该前导码配置信息指示的时频资源上，只接收该终端设备发送的前导码。换言之，在该前导码配置信息指示的时频资源上，邻小区不做针对其它终端设备的信号传输。
S840、邻小区测量接收到的前导码，并根据测量结果，以及该邻小区与服务小区之间的帧边界时间差，获取终端设备到该邻小区的TA。
其中，该邻小区与服务小区之间的帧边界时间差表示邻小区与服务小区的帧边界定时差，如图6中所示的t1。
邻小区可以自主获得该邻小区与服务小区之间的帧边界时间差。
或者，由服务小区或定位管理设备向邻小区发送该邻小区与服务小区之间的帧边界时 间差。
作为示例，计算两个小区之间的帧边界时间差的方式为，首先，两个小区各个小区中的基站上配备全球定位系统(global positioning system，GPS)，通过两个小区中的基站的GPS测量结果，可以计算出这两个小区的帧边界时间差。本申请对小区之间的帧边界时间差的确定方式不作限定。
可选地，该方法还可以包括：邻小区向定位管理设备发送步骤S840得到的终端设备到邻小区的TA。
应理解，定位管理设备根据终端设备到邻小区的TA可以计算出终端设备到邻小区的距离，进而基于邻基站的地理位置，可以获得终端设备的定位。
根据本申请图8所示的实施例的方案，通过服务小区向终端设备和邻小区发送前导码配置信息，邻小区可以通过接收并测量终端设备发送的前导码，获得终端设备到邻小区的TA。
应理解，步骤S810和步骤S820可以仅执行一次。
例如，终端设备与邻小区在首次接收到前导码配置信息之后，可以将其缓存在本地。在后续基于该前导码配置信息的信号传输过程中，可以直接使用该前导码配置信息进行前导码的发送(终端设备侧)和接收(邻小区侧)。即服务小区无需在每次前导码传输之前都向终端设备和邻小区发送前导码配置信息。
可选地，在一些实施例中，服务基站(即服务小区)包括具备定位管理功能的部件，例如为图3中所示的gNB，则步骤S820可以由服务小区执行。
可选地，在图8所示的实施例中，该方法还包括：服务小区根据该前导码配置信息接收终端设备发送的前导码，并根据对前导码的测量，确定终端设备到服务小区的TA。
在本实施例中，服务小区为终端设备分配前导码配置信息，并向终端设备和邻小区发送该前导码配置信息；终端设备基于该前导码配置信息发送前导码，服务小区和邻小区基于该前导码配置信息接收前导码。
在本实施例中，服务小区和邻小区均可以向定位管理设备发送各自的TA。定位管理设备可以根据服务小区的TA，获得终端设备到服务小区的距离，根据邻小区的TA，获得终端设备到邻小区的距离，从而结合服务小区和邻小区的地理位置，获得终端设备的定位。
作为示例，如图9所示，服务小区、邻小区1和邻小区2参与终端设备的定位。服务小区为终端设备分配前导码配置信息，并向终端设备、邻小区1和邻小区2发送该前导码配置信息；终端设备基于该前导码配置信息发送前导码，服务小区、邻小区1和邻小区2基于该前导码配置信息接收前导码。这三个小区可以通过测量前导码获得各自的TA。服务小区、邻小区1和邻小区2将各自的TA发送至定位管理设备。定位管理设备根据服务小区、邻小区1和邻小区2的TA，计算得到终端设备分别到服务小区、邻小区1和邻小区2的距离。根据终端设备分别到服务小区、邻小区1和邻小区2的距离，以及服务小区、邻小区1和邻小区2的地理位置，可以定位终端设备。
可选地，可以将结合图8描述的实施例中的前导码替换为上行参考信号。例如，该上行参考信号可以为下列中任一项：
探测参考信号(sounding reference signal，SRS)、解调参考信号(demodulation reference signal，DMRS)、信道质量指示(Channel Quality Indicator，CQI)、物理上行共享信道 (Physical Uplink Shared Channel，PUSCH)等。
还应理解，本申请提供的获取终端设备到邻小区的TA的方案，除了可以应用于如图1所示的终端设备定位方案，还可以应用于其它的需要获取终端设备到邻区基站的TA的场景。
还应理解，本申请中涉及的第一或第二等各种数字编号仅为描述方便进行的区分，并不用来限制本申请实施例的范围。
本申请中描述的各个实施例可以为独立的方案，也可以根据内在逻辑进行组合，这些方案都落入本申请的保护范围中。
可以理解的是，上述各个方法实施例中，由终端设备实现的方法和操作，也可以由可用于终端设备的部件(例如芯片或者电路)实现，由定位管理设备实现的方法和操作，也可以由可用于定位管理设备的部件(例如芯片或者电路)实现。
