具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
首先，对本申请中涉及的名词做出解释：
同步信号块(Synchronization Signal Block，SSB)：是通信标准中定义的一种信号结构，其包含主同步信号(Primary Synchronization Signal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)以及物理广播信道(Physical Broadcast Channel，PBCH)。
同步信号块是在基本的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)网格上传输的一组资源(资源单位)。在一些实施例中，所述一组资源为以下的至少一种：时域资源、频域资源、码域资源、时域资源和频域资源。图1示出了一个同步信号块的时域和频域结构。如图1所示，同步信号块在时域上持续4个OFDM符号。
同步信号块的子载波间隔可以为15KHz，30KHz，120KHz和240KHz。所有同步信号块在5ms时间内发送。为了支持波束(beam)发送，有beam时每个beam都需要发送SSB，所以5ms内可发送的同步信号块的数目最大为4(载频3GHz以下时)或8(载频3GHz～6GHz时)或64(载频6GHz以上时)。
在终端设备与网络设备进行初始同步时，终端设备检测到网络设备发送的其中一个同步信号块，获得了该同步信号块的同步信号块索引(SSB index)，从而得知该同步信号块所在的符号位置，因此终端设备与网络设备实现了下行的符号同步。而为了实现上行同步，终端设备需要发送随机接入前导码(preamble)，而这个随机接入前导码如何选择，以及这个随机接入前导码在哪个随机接入机会(Random access channel Occasion，RO)上发送，是根据终端设备接收到的这个同步信号块以及网络设备实际发送了哪些同步信号块以及RO的位置集合来决定的。具体过程如下：
第一步：终端设备检测到自己接收到的这个同步信号块的SSB index为SSB#1。
第二步：终端设备接收网络设备发送的系统信息块1(System Information Block 1，SIB1)的消息，指示网络设备实际发送了哪些同步信号块。
其中，网络设备使用两个8bit来指示实际发送了哪些同步信号块。因为同步信号块最大可发送位置为64，将64个同步信号块分为8组，每组内的8个同步信号块位置连续。即SSB#0～#7为第一组，SSB#8～15为第二组……SSB#56～#63为第八组。那么两个8bit中，第一个8bit指示哪些组有同步信号块发送，比如第一个8bit为00000001(左边为高位，右边为低位)，即表示只有第一组有同步信号块发送。那第二个8bit指示有同步信号块发送的这些组内是发送了哪些位置的同步信号块，比如第二个8bit为10011011，则表示第一组内发送了SSB#0，#1，#3，#4，#7。
第三步，通过第一步和第二步，终端设备知道了自己接收到的这个SSB#1是网络设备发送的5个同步信号块中的第二个。
第四步，终端设备接收网络设备发送的SIB1，获得SSB-perRACH-Occasion信息，该信息标识一个RO内的前导码需要分配给多少个实际发送的同步信号块。
SSB-perRACH-Occasion取值为{1/8,1/4,1/2,1,2，4，8，16}，当该参数为1/8时，表示该SSB占用8个连续的RO。而当该参数为8时，表示8个实际发送的连续的SSB共享该RO，但使用不同的前导码，比如将64个前导码分成连续的8组，每个同步信号块对应其中一组前导码。
同时,终端设备接收网络设备发送的SIB1，获得频分多路复用 (Frequency-Division Multiplexing，FDM)的RO的个数取值，其取值可能为{1,2,4,8}中的一个。示例性的，若取值为2，表示同一时间，有两个处在不同频域的RO。而RO的编号是先频域后时域。比如SSB-perRACH-Occasion为2，FDM的RO的个数取值为2时，同步信号块对应的RO如图2所示。
图3示出了本公开一个示例性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端设备14。
接入网12中包括若干个网络设备120。网络设备120可以是基站，所述基站是一种部署在接入网中用以为终端设备提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一描述可能会变化。为方便本公开实施例中的描述，上述为终端设备14提供无线通信功能的装置统称为网络设备。
终端设备14可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或物联网(Internet of Things，IoT)设备或工业物联网(Industry Internet of Things，IIoT)设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端设备。网络设备120与终端设备14之间通过某种空口技术互相通信，例如Uu接口。
本公开实施例的技术方案可以应用于各种通信系统，例如：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、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。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，车辆间(Vehicle to Vehicle，V2V)通信以及车联网(Vehicle to Everything，V2X)系统等。本公开实施例也可以应用于这些通信系统。
图4示出了本公开一个示例性实施例提供的定位方法的流程图，可以应用于如图3所示的终端设备和网络设备中。该方法包括：
步骤400，终端设备确定多个同步信号块。
在本公开实施例中，终端设备确定多个同步信号块的方式可以为很多种，例如：
可以根据通信协议的规定和网络侧设备的配置，以及网络侧设备发送的同步信号块来确定多个同步信号块。
在本公开的以下实施例中，采用该方式作为例子进行说明，即以下的步骤410和步骤420是由网络侧的网络设备将多个同步信号块发送到终端设备。而每个同步信号块会携带自身的同步信号块标识，终端设备通过通信协议规定的同步信号块标识指示方法，接收每个同步信号块并解码，即可获得每个同步信号块标识，即确定每个同步信号块。当然，本领域内技术人员可以理解，步骤410和步骤420对应的实施方式，只是步骤400所限定的多种实施方式中的一种，本公开实施例中仅仅是采用步骤410和步骤420对应的实施方式进行举例说明，而并非是对本公开实施例的范围的限定。
步骤410，网络设备向终端设备发送多个同步信号块。
可选地，网络设备包含一个或多个网络设备，比如一个或多个小区所在网络设备，包括终端设备的服务小区所在网络设备和邻小区所在网络设备；又比如一个或多个发送接收点(Transmission Reception Point，TRP)所在网络设备，多个TRP可以属于终端设备的服务小区或邻小区。
可以理解的是，多个同步信号块来自不同小区的不同TRP；或，来自相同小区的不同TRP；或，来自相同小区的相同TRP。
结合参考图5，终端设备510处于服务小区(serving cell)之中，也处于邻小区(neighboring cell)之中。其中，每个小区可以由不止一个TRP来覆盖。如图5所示，服务小区由TRP 1和TRP 2联合覆盖，从而增大了服务小区的覆盖半径。邻小区由TRP 3覆盖。
假设网络设备向终端设备发送了两个同步信号块，这两个同步信号块可以均来自TRP 3(即相同小区的相同TRP)；可以来自于TRP 1和TRP 2(即相同小区的不同TRP)；可以来自于TRP 1和TRP 3(即不同小区的不同TRP)。
步骤420，终端设备接收多个同步信号块。
在第五代移动通信(5G)系统中，5G无线资源控制(Radio Resource Control，RRC)支持三种状态，分别是RRC_IDLE状态(即空闲态)、RRC_INACTIVE状态(即非激活态)及RRC_CONNECTED状态(即连接态)。随着后续技术的演进，可能会增加其他状态；且前述这些状态可能会被改变名称。但是这些改变都不影响本公开实施例的技术方案的可实施性和完整性；且这些名称的改变也应视为在本公开实施例的保护范围内。
在一种可能的实现方式中，在终端设备接收同步信号块时，终端设备处于空闲态。在另一种可能的实现方式中，在终端设备接收同步信号块时，终端设备处于非激活态。在另一种可能的实现方式中，终端设备处于连接态，但发生了波束失败(beam failure)或无线链路失败(Radio Link Failure，RLF)。
可以理解的是，对于来自不同小区的同步信号块，终端设备可以根据物理小区标识(Physical Cell ID，PCI)进行区分。
步骤430，终端设备将多个同步信号块分成M个同步信号块组。
其中，M为正整数。M是PCI相同的同步信号块被分组的分组数量。即，终端设备根据具有相同的PCI的多个同步信号块，将多个同步信号块分成M个同步信号块组。
终端设备在接收到多个同步信号块之后，在多个同步信号块来自同一小区的情况下，对多个同步信号块进行分组，将多个同步信号块分成1个同步信号块组(即M等于1)，或多个同步信号块组(即M大于1)。每个同步信号块组中同步信号块的数量相同或不同。在多个同步信号块来自不同小区的情况下，终端设备首先根据PCI将来自不同小区的同步信号块进行拆分，对属于同一个小区的同步信号块进行分组，分成M组。如：终端设备接收到的同步信号块来自两个小区(小区1和小区2)，则终端设备首先根据PCI将所有的同步信号块 分成两部分，分别对应于小区1和小区2，再将来自小区1的同步信号块分成M 1组，来自小区2的同步信号块分成M 2组，M 1和M 2相同或不同，也就是说，终端设备将多个同步信号块共分成M 1加M 2组。
在一种可能的实现方式中，属于同一同步信号块组的同步信号块来自同一TRP。在另一种可能的实现方式中，属于同一同步信号块组的同步信号块可能来自相同的TRP，也可能来自不同的TRP。在一种可能的实现方式中，来自相同的TRP的同步信号块被分成一个组。在另一种可能的实现方式中，来自相同的TRP的同步信号块被分成两个或两个以上的组。
步骤440，终端设备针对每个同步信号块组，在属于同一同步信号块组的N个同步信号块对应的随机接入资源上，发送N个同步信号块对应的随机接入前导码。
对于M个同步信号块组中的任意一个同步信号块组，终端设备在该同步信号块组中的N个同步信号块对应的随机接入资源上，发送N个同步信号块对应的随机接入前导码(preamble)，N为正整数。
可以理解的是，在本公开的所有实施例中，M个同步信号块组各自所对应的N值可以相同，也可以不同；或者对于服务小区的多个同步信号块进行分组并发送随机接入前导码的情况下的N值与对于邻小区的多个同步信号块进行分组并发送随机接入前导码的情况下的N值可以相同，也可以不同。即，所述M个同步信号块组中所包含的同步信号块的数量可以全部相同，也可以全部不相同，还可以是部分同步信号块组包含的同步信号块的数量相同且其他部分同步信号块组包含的同步信号块的数量不同；即，N＝(N 1,N 2,……N M)，其中M为对应的同步信号块组。本公开实施例对此不进行限制。
其中，随机接入资源是用于定位用途的资源，该资源可以为以下的至少一种：时域资源、频域资源、码域资源、时域资源和频域资源。可选地，N个同步信号块对应的时域资源、频域资源、码域资源中的至少一项不同。码域资源包含随机接入前导码。
在本公开实施例中，N个同步信号块可以一一对应于N个随机接入资源，也可以是其中的一个同步信号块对应于两个或两个以上随机接入资源，还可以是其中两个或两个以上同步信号块对应于一个随机接入资源。
其中，随机接入前导码用于进行定位。可选地，随机接入前导码用于供网络设备对终端设备进行定位测量，确定终端设备的地理位置。
在本公开实施例中，N个同步信号块可以一一对应于N个随机接入前导码，也可以是其中的一个同步信号块对应于两个或两个以上随机接入前导码，还可以是其中两个或两个以上同步信号块对应于一个随机接入前导码。
可选地，终端设备期望属于同一同步信号块组的N个同步信号块来自同一个TRP。通过N的数值，终端设备可以控制针对一个TRP发送的随机接入前导码所对应的同步信号块的数量，避免参与定位测量的多个随机接入前导码都发送到一个TRP。
步骤450，网络设备针对每个同步信号块组，在属于同一同步信号块组的N个同步信号块对应的随机接入时频资源上，接收N个同步信号块对应的随机接入前导码。
对于M个同步信号块组中的任意一个同步信号块组，网络设备在该同步信号块组中的N个同步信号块对应的随机接入资源上，接收N个同步信号块对应的随机接入前导码，N为正整数。
可选地，网络设备在接收随机接入前导码后，将对随机接入前导码进行测量，得到测量结果，根据测量结果对终端设备进行定位。其中，测量结果包括但不限于：角度测量值、时间测量值和信号强度测量值中的至少一种。
时间测量值包括但不限于：参考信号时间差(Reference Signal Time Difference，RSTD)，接收发射时间差(Rx–Tx time difference)中的至少一种；信号强度测量值包括但不限于：参考信号接收功率(Reference Signal Receiving Power，RSRP)，参考信号接收质量(Reference Signal Received Quality，RSRQ)，接收信号强度指示(Received signal strength indicator，RSSI)中的至少一种；角度测量值包括但不限于：出发角(Angle of Departure，AoD)和到达角(Angle of Arrival，AoA)中的至少一种。
综上所述，本实施例提供的方法，网络设备向终端设备发送多个同步信号块，使得终端设备能够在对多个同步信号块进行分组后，在每个同步信号块组中的N个同步信号块对应的随机接入资源上，发送N个同步信号块对应的随机接入前导码，进而网络设备能够根据随机接入前导码进行定位测量，通过利用随机接入资源，提供了一种终端设备在进行随机接入时也能进行定位的方法。
同时，本实施例提供的方法，通过对多个同步信号块进行分组，只针对每个同步信号块组中的N个同步信号块发送随机接入前导码，避免了针对同一个TRP发送了过多的随机接入前导码，导致终端设备的功耗过大的问题。
本公开实施例中提出了一种对多个同步信号块进行分组的方法。在本公开的所有实施例中，对多个同步信号块进行分组的方法可以结合本公开的任意一个实施例一起使用，也可以单独使用，本公开实施例并不对此做出限定。但是为了使得技术方案更容易被理解，本公开的以下实施例结合前述的实施例进行举例说明，即通过得到M个同步信号块组的方法进行示例性的说明。
在基于图4的可选实施例中，图6示出了本公开一个示例性实施例提供的定位方法的流程图，可以应用于如图3所示的终端设备和网络设备中。在本实施例中，步骤430替换实现为步骤431或步骤432。当然，本领域内技术人员可以理解，在本公开实施例的以下的两个技术方案独立实施时，其构成了至少三个完全独立的实施例：一个实施例包括步骤400、步骤431；另一个实施例包括步骤400、步骤432；又一个实施例包括步骤400、步骤431、步骤432。
步骤400，终端设备确定多个同步信号块。
步骤431，终端设备确定分组数量M。
终端设备在进行分组之前，需要确定分组数量M。可选地，终端设备通过如下两种实现方式中的一种确定分组数量M。本领域内技术人员可以理解，在本公开的所有实施例中，以下的两种实现方式(即：实现方式一、实现方式二)可以结合本公开的任意一个实施例一起使用，也可以单独使用，本公开实施例并不对此做出限定。但是为了使得技术方案更容易被理解，本公开的以下实施例结合前述的实施例进行举例说明，以说明本公开实施例中如何确定分组数量M。当然，这只是一种举例说明；本领域内技术人员可以理解，以下的两种实现方式(即：实现方式一、实现方式二)完全可以脱离步骤400或步骤410或步骤420或步骤432独立执行，以形成两个完全独立的技术方案；本公开实施例并不对此作出限定。即，以下的两种实现方式可以独立被实施，也可以结合之前的任何一个步骤一起被实施。
实现方式一：终端设备将网络设备包含的TRP的数量，确定为分组数量M。
终端设备需要获取网络设备包含的TRP的数量，并将网络设备包含的TRP的数量确定为分组数量M。可以理解的是，在本公开的所有实施例中，M个分组中的每个分组分别对应一个不同的TRP。在一些可替代的实施例中，M个分组中至少存在其中一个分组对应两个或两个以上的TRP，或是M个分组中至少存在其中一个分组对应一个TRP集合。本公开实施例对此不进行限制。
可选地，终端设备接收来自定位管理功能(location Management Function，LMF)网元的第一指示信息，根据第一指示信息确定网络设备包含的TRP的数量。
也就是说，网络设备包含的TRP的数量可以由LMF网元配置给终端设备。
可选地，终端设备接收来自服务小区的第二指示信息，根据第二指示信息确定网络设备包含的TRP的数量。
也就是说，网络设备包含的TRP的数量可以由网络设备配置给终端设备。具体地，第二指示信息可以是如下信息中的任意一种：
一、广播信息。
示例性的，网络设备包含的TRP的数量包括在物理广播信道(Physical Broadcast Channel，PBCH)发送的主信息块(Master Information Block，MIB)中，由网络设备广播给终端设备。
二、系统信息。
系统信息包括剩余最少系统信息(Remaining Minimum System Information，RMSI)(即SIB1)和其它系统信息(Other System Information)。其他系统信息包括系统信息中除了SIB1之外的任意一种，比如SIB2，SIB3，SIB4……。
三、定位参考信号配置信息。
示例性的，终端设备接收过服务小区发送的定位参考信号(Positioning Reference Signal，PRS)，PRS配置信息中配置有发送该PRS的TRP ID，或者PRS携带发送该PRS的TRP ID。该PRS可以是终端设备在连接态或非连接态(包括RRC_IDLE状态和RRC_INACTIVE状态)接收的。所以终端设备能够根据不同的TRP ID，确定网络设备包含的TRP的数量。
四、服务小区在终端设备连接态时已传输的信令。
示例性的，在该终端处于连接态时，网络设备使用RRC信令告知终端设备网络设备包含的TRP的数量。
需要说明的是，这里网络设备包含的TRP的数量，主要是针对属于同一个小区的网络设备包含的TRP数量。因为如果是不同小区，可以根据物理小区标识(Physical Cell ID，PCI)来区分属于不同小区的TRP。而终端针对接收到的多个同步信号块，首先根据PCI进行分组，再将PCI相同的多个同步信号块分成M个同步信号块组。但是属于同一小区即PCI相同的TRP如何区分或确定属于同一小区的TRP的数目，就可以依照上述四种方法。
实现方式二：终端设备根据第一对应关系，确定分组数量M；其中，第一对应关系中包括分组数量M与网络设备支持发送的同步信号块的第一最大数目之间的对应关系。可以理解的是，在本公开的所有实施例中，M个分组中的每个分组分别对应一个不同的TRP。在一些可替代的实施例中，M个分组中至少存在其中一个分组对应两个或两个以上的TRP，或是M个分组中至少存在其中一个分组对应一个TRP集合。本公开实施例对此不进行限制。
终端设备能够根据默认规则，如：第一对应关系，确定分组数量M。可选地，第一对应关系是在协议中预配置且存储在终端设备芯片中的。
第一最大数目是网络设备支持发送的同步信号块的可能的最大数目。在不同的载频下，网络设备支持发送的同步信号块的最大数目不同。如：网络设备5ms内可发送的同步信号块的数目最大为4(载频3GHz以下时)或8(载频3GHz～6GHz时)或64(载频6GHz以上时)。可选地，第一最大数目包括但不限于：4、8、64。
第一对应关系可以是一一对应关系，即：一种第一最大数目对应于一个分组数量M。第一对应关系也可以不是一一对应关系，即：一种第一最大数目对应于一个或多个分组数量M。示例性的，结合参考如下表一：
表一
第一最大数目 分组数量M
4 2
8 2或4
64 2或4或8
在表一中，一种第一最大数目有可能对应于一个分组数量M，如：在第一最大数目是4时，分组数量M是2。一种第一最大数目也有可能对应于多个分组数量M，如：在第一最大数目是8时，分组数量M是2或4。
在第一对应关系是一一对应关系的情况下，终端设备确定网络设备支持发送的同步信号块的第一最大数目后，即可根据第一对应关系，直接确定分组数量M。
在第一对应关系不是一一对应关系的情况下，即：第一最大数目对应有至少两个分组数量M的情况下，终端设备可以根据如下方式中的任意一种，在至少两个分组数量M中确定出目标分组数量：
一、终端设备根据同步信号块所处的载频，在至少两个分组数量M中确定 出目标分组数量。
可选地，同步信号块所处的载频与分组数量M正相关。即：同步信号块所处的载频越高，分组数量M越大。
二、终端设备根据来自服务小区的第三指示信息，在至少两个分组数量M中确定出目标分组数量。
示例性的，第三指示信息是RMSI即SIB1或其它系统信息或RRC信令。如：在第一最大数目是8时，分组数量M是2或4的情况下，终端设备可以根据RMSI即SIB1或其它系统信息或RRC信令中的1bit指示位的指示，在2和4中确定出目标分组数量。
示例性的，第三指示信息是定位参考信号配置信息。定位参考信号配置信息中配置有发送该定位参考信号的TRP ID。终端设备能够根据不同的TRP ID，确定网络设备包含的TRP的数量。终端设备根据网络设备包含的TRP的数量，在至少两个分组数量M中，可以将略大于网络设备包含的TRP的数量的分组数量M确定为目标分组数量。如：在第一最大数目是8时，分组数量M是2或4的情况下，终端设备确定网络设备包含的TRP的数量为3，则终端设备将4确定为目标分组数量。
三、终端设备根据来自LMF网元的第四指示信息，在至少两个分组数量M中确定出目标分组数量。
示例性的，第四指示信息是定位协议，包括但不限于长期演进定位协议(LTE Positioning Protocol，LPP)信息和新无线定位协议(NR Positioning Protocol)；还可以是今后的任意一代通信技术中的定位协议。如：在第一最大数目是8时，分组数量M是2或4的情况下，终端设备可以根据定位协议信息中的1bit指示位的指示，在2和4中确定出目标分组数量。
步骤432，终端设备根据分组数量M，将多个同步信号块分成M个同步信号块组。
在终端设备确定了分组数量M之后，即可将多个同步信号块分入M个同步信号块组中。
可选地，终端设备通过如下方式，将多个同步信号块分成M个同步信号块组：
确定网络设备支持发送的同步信号块的第二最大数目；确定第二最大数目个同步信号块的编号与M个同步信号块组之间的第二对应关系；确定接收到的 多个同步信号块的编号；根据第二对应关系，将多个同步信号块分成M个同步信号块组。
其中，在第二对应关系中，同步信号块的编号与同步信号块组一一对应。可选地，第二对应关系是在协议中预配置且存储在终端设备芯片中的，或，第二对应关系是网络设备配置的，或，第二对应关系是LMF网元配置的。
示例性的，第二最大数目是4，M为2。网络设备支持发送的同步信号块包括：SSB#0，SSB#1，SSB#2，SSB#3。终端设备可以获取上述4个同步信号块与2个同步信号块组之间的第二对应关系。
在一种可能的第二对应关系中，属于同一同步信号块组的同步信号块的编号连续。结合参考如下表二：
表二
同步信号块组 同步信号块
第一同步信号块组 SSB#0，SSB#1
第二同步信号块组 SSB#2，SSB#3
每个同步信号块组包含编号连续的多个同步信号块，如第一同步信号块组包含SSB#0，SSB#1；第二同步信号块组包含SSB#2，SSB#3。
在另一种可能的第二对应关系中，属于同一同步信号块组的同步信号块的编号不连续。结合参考如下表三：
表三
同步信号块组 同步信号块
第一同步信号块组 SSB#0，SSB#2
第二同步信号块组 SSB#1，SSB#3
每个同步信号块组包含编号不连续的多个同步信号块，如第一同步信号块组包含SSB#0，SSB#2；第二同步信号块组包含SSB#1，SSB#3。
而实际上，终端设备只接收到3个同步信号块：SSB#1，SSB#2，SSB#3。则终端设备可以根据确定好的第二对应关系，对自身接收到的同步信号块进行分组。如：在表二示出的第二对应关系中，终端设备将SSB#1分入第一同步信号块组，将SSB#2和SSB#3分入第二同步信号块组；在表三示出的第二对应关系中，终端设备将SSB#2分入第一同步信号块组，将SSB#1和SSB#3分入第二同步信号块组。
步骤440，终端设备针对每个同步信号块组，在属于同一同步信号块组的N 个同步信号块对应的随机接入资源上，发送N个同步信号块对应的随机接入前导码。
可选地，在终端设备需要发送随机接入前导码时，如何选择这个随机接入前导码，以及这个随机接入前导码在什么随机接入时域资源和随机接入频域资源(即RO)上发送，是根据终端设备接收到的这个同步信号块以及网络设备实际发送的同步信号块以及RO的位置集合来决定的。具体地，参见上述过程说明。
可选地，N个同步信号块的RSRP均大于RSRP阈值。
终端设备对同步信号块的RSRP进行测量。RSRP是在某个符号内承载参考信号的所有资源单元(Resource Element，RE)上接收到的信号功率的平均值。
其中，RSRP阈值是针对定位用途的阈值。上述RSRP阈值与用于随机接入或用于备选波束(candidate beam)确定的阈值独立，即上述RSRP阈值与另外两种阈值的取值可以一样，也可以不一样。
步骤450，网络设备针对每个同步信号块组，在属于同一同步信号块组的N个同步信号块对应的随机接入时频资源上，接收N个同步信号块对应的随机接入前导码。
综上所述，本实施例提供的方法，终端设备可以根据网络设备包含的TRP的数量确定出分组数量，也可以根据分组数量M与网络设备支持发送的同步信号块的第一最大数目之间的第一对应关系确定出分组数量，并将接收到的多个同步信号块分成M个同步信号块组，使得每个同步信号块组内的N个同步信号块都来自于同一个TRP，避免针对同一TRP发送过多的随机接入前导码。
下面，对终端设备实际用于定位的同步信号块的数量N进行示例性的说明。
在基于图4的可选实施例中，N的取值是预配置的；或，N的取值是根据配置信息配置的，配置信息来自网络设备或LMF网元。
配置信息可以是来自网络设备的系统信息，包括剩余最少系统信息(Remaining Minimum System Information，RMSI)(即SIB1)和其它系统信息(Other System Information)。其他系统信息包括系统信息中除了SIB1之外的任意一种，比如SIB2，SIB3，SIB4……。
可以理解的是，N是配置的一个最大值。在某一同步信号块组中的同步信号块的数量小于N的情况下，终端设备实际上发送的随机接入前导码所对应的同步信号块的数目小于N。
可选地，针对不同的同步信号块组，N的取值独立；或，针对不同的同步信号块组，N的取值相同；或，针对至少两个同步信号块组，N的取值相同。
示例性的，针对M个同步信号块组，每个同步信号块组的N都为1。
当N为1时，表明针对一个TRP，最多只针对一个同步信号块发送随机接入前导码，那么各个TRP根据各自接收到的一个随机接入前导码进行定位测量，最后根据第一数量个TRP的定位测量结果和第一数量个TRP的位置计算出终端的位置。
示例性的，M个同步信号块组中，存在两个同步信号块组，N的取值相同，都为2。
当N为2时，这两个同步信号块的发送波束和/或接收波束不同。表明针对一个TRP，最多可针对两个同步信号块发送随机接入前导码，那么各个TRP根据各自接收到的两个随机接入前导码进行定位测量，最后根据第二数量个TRP的定位测量结果和第二数量个TRP的位置计算出终端的位置。
其中，当N为2时的TRP的第二数量小于或等于N为1时的TRP的第一数量。
