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NR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)，而这个前导码如何选择，以及这个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。
随机接入过程
随机接入过程是指从终端设备发送前导码开始尝试接入网络到与网络间建立起基本的信令连接之前的过程，随机接入过程是对于任意一个蜂窝通信系统的最基本要求之一，用于使终端设备与网络侧建立数据通信。
随机接入过程分为：四步(4-step)随机接入和两步(2-step)随机接入。
四步随机接入
图3示出了在基于竞争的随机接入过程中，随机接入过程的4个步骤包括：
(1)终端设备设备向网络设备发送消息1：前导码(preamble)。
终端设备向网络设备发送前导码(preamble)，网络设备据此估计终端设备 设备的传输时延以实现上行同步。
(2)网络设备向终端设备发送消息2：随机接入响应(Random Access Response,RAR)。
网络设备基于上述步骤(1)中估计得到的传输时延，发送时间提前(timing advance)命令，以调整终端设备的发送时间。消息2由网络设备的媒体接入控制层(Media Access Control，MAC)组织，并由下行共享信道(Down Link Share Channel，DL_SCH)承载。
网络设备采用物理下行控制信道(Physical Downlink Control Channel，PDCCH)调度消息2，并通过C-RNTI或RA-RNTI进行寻址(也称加扰)，RA-RNTI由承载消息1的物理随机接入信道(Physical Random Access Channel，PRACH)时频资源位置确定。消息2包含上行传输定时提前量，为消息3分配上行资源和临时C-RNTI。
(3)终端设备向网络设备发送消息3：第一次调度传输。
终端设备在收到消息2后，在分配的上行资源上传输消息3，通过物理上行共享信道(Physical Uplink Share Channel，PUSCH)向网络设备发送用户设备身份(User Equipment Identify，UE ID)。
(4)网络设备向终端设备发送消息4：竞争解决消息。
网络设备在物理下行共享信道(Physical Downlink Share Channel，PDSCH)上发送给终端设备的竞争解决消息。
两步随机接入
在基于竞争的随机接入的过程中，可以将4步的随机接入过程合并成2步的随机接入过程，结合图4，合并后包括消息A和消息B，相关步骤包括：
(1)终端设备向网络设备发送消息A。
(2)网络设备接收到终端设备发送的消息A后，向终端设备发送消息B。
可选地，消息A包括消息1和消息3的内容，也即消息A包括：前导码和UE ID，UE ID可以是：小区无线网络临时标识符(Cell Radio Network Temporary Identifier，C-RNTI)、临时C-RNTI、随机接入无线网络临时标识符(Random Access Radio Network Temporary Identifier，RA-RNTI)、非接入层(Non-Access Stratum)UE ID中的一种。
可选地，消息B包括消息2和消息4的内容，也即消息B包括：随机接入响应和竞争解决消息。
图5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5所示的终端设备和网络设备中。该方法包括：
步骤610，网络设备向终端设备发送n个同步信号块。
其中，n为大于或等于2的整数。
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。各个网络设备以波束扫描的方式发送同步信号块，即以时分复用的形式在不同波束上发送不同的同步信号块。网络设备可以周期性的发送同步信号块，周期可以是5ms、10ms、20ms……。不同网络设备可以同时在不同的波束上发送相同或不同的同步信号块。
可选地，n的数值是网络设备或者定位管理功能(location Management Function，LMF)或接入移动管理功能(Access and Mobility Management Function，AMF)确定的，或是在协议中预配置且存储在终端设备芯片中的。可选地，为了实现更高精度的定位，n为大于或等于3的整数。即：网络设备向终端设备发送3个或3个以上的同步信号块。
步骤620，终端设备接收n个同步信号块。
终端设备接收网络设备发送的n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)。当然，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。
可选地，在终端设备接收同步信号块时，终端设备处于空闲态。在空闲态下，寻呼由核心网(Core Network，CN)发起，寻呼区域由CN配置，网络设 备侧不存在UE接入层(Access Stratum，AS)上下文，不存在RRC连接。
可选地，在终端设备接收同步信号块时，终端设备处于非激活态；或者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)。
步骤630，终端设备确定与n个同步信号块对应的n个定位随机接入资源。
在本公开实施例中，n个同步信号块可以一一对应于n个定位随机接入资源，也可以是其中的一个同步信号块对应于两个或两个以上定位随机接入资源，还可以是其中两个或两个以上同步信号块对应于一个定位随机接入资源。
因此步骤630还可以为：终端设备确定与n个同步信号块对应的m个定位随机接入资源。其中n＝m，或n≠m。
其中，定位随机接入资源是用于定位用途的随机接入资源。可选地，定位随机接入资源包括但不限于：随机接入时域资源、随机接入频域资源和前导码中的至少一种。
每个同步信号块都有与其对应的定位随机接入资源，终端设备接收一个同步信号块之后，可以确定与该同步信号块对应的定位随机接入资源。
步骤640，终端设备根据n个定位随机接入资源进行定位用途参考信号的发送。
在另一些实施例中，该步骤640还可以为：终端设备根据n个定位随机接入资源确定定位用途参考信号。
其中，定位用途参考信号是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的参考信号。此时，定位用途参考信号是一种上行参考信号。可选地，定位用途参考信号包括：随机接入前导码。
在确定好n个同步信号块对应的定位随机接入资源后，终端设备在n个随机接入资源上分别发送n个定位用途参考信号，网络设备根据定位用途参考信号进行定位测量。
在一些实施例中，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，终端设备向同一小区发送n个定位用途参考信号，或，向不同小区发送n个定位用途参考信号；终端设备向同一小区的一个或多个TRP发送n个定位用途参考信号，或，向不同小区的一个或多个TRP发送n个定位用途参考信号。
综上所述，本实施例提供的方法，网络设备向终端设备发送n个同步信号块，使得终端设备能够使用与n个同步信号块对应的n个定位随机接入资源，针对多个同步信号块分别发送定位用途参考信号，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，相比于终端设备只针对一个同步信号块发送定位用途参考信号的定位方法，通过增加定位用途参考信号的数量使得多个网络设备能针对该终端进行定位测量，提高了定位的精度。
在基于图6的可选实施例中，图7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5所示的终端设备和网络设备中。在本实施例中，步骤640替换实现为步骤641，还包括步骤650：
步骤610，网络设备向终端设备发送n个同步信号块。
其中，n为大于或等于2的整数。
终端设备与网络设备可以基于多TRP进行通信。在一种实现方式中，n个同步信号块来自不同小区的不同TRP。在另一种实现方式中，n个同步信号块来自相同小区的不同TRP；在另一种实现方式中，n个同步信号块来自相同小区的相同TRP。
也就是说，网络设备可以通过不同小区的不同TRP发送n个同步信号块；或，通过不同小区的相同TRP发送n个同步信号块；或，通过相同小区的相同TRP发送n个同步信号块。
示例性的，结合参考图8，终端设备810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2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。
在n为3时，网络设备向终端设备发送3个同步信号块。这3个同步信号块可以都来自于服务小区的TRP 1(即相同小区的相同TRP)；可以来自于服务小区的TRP 1和TRP 2(即相同小区的不同TRP)；可以来自于服务小区的TRP 1、服务小区的TRP 2和邻小区的TRP 3(即不同小区的不同TRP)。
步骤620，终端设备接收n个同步信号块。
在一种实现方式中，n个同步信号块来自不同小区的不同TRP；在另一种实现方式中，n个同步信号块来自相同小区的不同TRP；在另一种实现方式中，n 个同步信号块来自相同小区的相同TRP。
可选地，终端设备对同步信号块的参考信号接收功率(Reference Signal Receiving Power，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。对于n个同步信号块中的每个同步信号块，终端设备测得的同步信号块的RSRP大于RSRP阈值。
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。
可选地，在n个定位随机接入资源对应的随机接入信道的资源上，终端设备使用不同的发送波束发送n个定位随机接入资源对应的前导码。
示例性的，终端设备对应有多个天线面板，终端设备使用不同的天线面板(对应不同的发送波束)或相同天线面板的不同发送波束，向不同小区或相同小区的多个不同TRP或同一TRP分别发送n个定位随机接入资源对应的前导码。
可选地，在n个定位随机接入资源对应的随机接入信道的资源上，终端设备使用不同或相同的发送功率发送n个定位随机接入资源对应的前导码。也就是说，n个同步信号块对应的前导码的发送功率相同或不同。
步骤630，终端设备确定与n个同步信号块对应的n个定位随机接入资源。
其中，定位随机接入资源是用于定位用途的随机接入资源。
可选地，定位随机接入资源包括：随机接入时域资源、随机接入频域资源和前导码中的至少一种。其中，n个同步信号块对应的随机接入时域资源、随机接入频域资源和前导码中的至少一项不同。
步骤641，终端设备在n个定位随机接入资源对应的随机接入信道的资源上，分别发送n个定位随机接入资源对应的前导码。
定位用途参考信号包括前导码。
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前导码。
因此步骤641还可以为：终端设备确定与n个同步信号块对应的L个前导码。其中n＝L，或n≠L。
可选地，在终端设备需要发送随机接入资源对应的前导码时，如何选择这个前导码，以及这个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。
在一种实现方式中，n个前导码分别发送至不同小区的不同TRP。在另一种实现方式中，n个前导码分别发送至相同小区的不同TRP。在另一种实现方式中，n个前导码分别发送至相同小区的相同TRP。
示例性的，结合参考图8。在n为3时，终端设备向网络设备发送3个前导码。这3个前导码可以都发送至邻小区的TRP 3(即相同小区的相同TRP)；可以发送至服务小区的TRP 1和TRP 2(即相同小区的不同TRP)；可以发送至服务小区的TRP 1、服务小区的TRP 2和邻小区的TRP 3(即不同小区的不同TRP)。
步骤650，网络设备在n个定位随机接入资源对应的随机接入信道的资源上，分别接收n个定位随机接入资源对应的前导码。
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前导码。
因此步骤650还可以为：网络设备在n个定位随机接入资源对应的随机接入信道的资源上，分别接收L个定位随机接入资源对应的前导码；其中n＝L，或n≠L。
由于终端设备在n个定位随机接入资源对应的随机接入信道的资源上，分别发送n个定位随机接入资源对应的前导码，相应地，网络设备在n个定位随机接入资源对应的随机接入信道的资源上，分别接收n个定位随机接入资源对应的前导码。
在一种实现方式中，网络设备在n个定位随机接入资源对应的随机接入信道的资源上，通过不同小区的不同TRP分别接收n个定位随机接入资源对应的前导码。在另一种实现方式中，网络设备在n个定位随机接入资源对应的随机接入信道的资源上，通过相同小区的不同TRP分别接收n个定位随机接入资源对应的前导码。在另一种实现方式中，网络设备在n个定位随机接入资源对应的随机接入信道的资源上，通过相同小区的相同TRP分别接收n个定位随机接入资源对应的前导码。
可选地，在网络设备接收到n个定位随机接入资源对应的前导码后，网络 设备测量n个定位随机接入资源对应的前导码，获得测量值；测量值包含定位随机接入资源对应的前导码的时间测量值，前导码的信号强度测量值和前导码的角度测量值中的至少一项。
其中，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：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。网络设备可以使用上述测量值进行定位计算，或者网络设备可以将上述测量值上报给LMF，LMF进行定位计算。
可选地，在终端设备发送n个定位随机接入资源对应的前导码之后，终端设备执行如下步骤：
一、确定与n个定位随机接入资源对应的n个随机接入反馈窗口时间。
定位随机接入资源对应有随机接入反馈窗口时间。可选地，随机接入反馈窗口时间由高层参数配置。
在本公开实施例中，n个同步信号块可以一一对应于n个随机接入反馈窗口时间，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反馈窗口时间，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反馈窗口时间。
因此上述步骤还可以为：确定与n个定位随机接入资源对应的p个随机接入反馈窗口时间。其中n＝p，或n≠p。
二、在n个随机接入反馈窗口时间内检测随机接入反馈，确定反馈时间。
其中，随机接入反馈是对前导码的反馈，反馈时间是检测到随机接入反馈的时间。
可选地，在网络设备成功接收到前导码的情况下，网络设备将会向终端设备发送相应的随机接入反馈。终端设备在随机接入反馈窗口时间内检测随机接入反馈，在检测到随机接入反馈时，将检测到随机接入反馈的时间确定为反馈时间。
与前述的一步骤相似的，上述二步骤还可以为：在p个随机接入反馈窗口时间内检测随机接入反馈，确定反馈时间。
三、确定时间差值。
其中，时间差值是反馈时间与随机接入反馈对应的前导码的发送时间的差值，时间差值用于进行定位计算。
在一种实现方式中，终端设备向网络设备发送时间差值。在另一种实现方式中，终端设备向定位管理功能(Location Management Function，LMF)网元发送时间差值。
示例性的，网络设备接收终端设备侧确定的时间差值，确定网络设备与终端设备之间的距离。
综上所述，本实施例提供的方法，终端设备针对n个同步信号块，分别向多个TRP或多个小区所在网络设备发送前导码，便于多个TRP或多个小区所属网络设备参与到定位测量，最终提高定位的精确性，减少定位时延。
本实施例提供的方法，终端设备进一步在多个随机接入反馈窗口接收来自各个TRP或多个小区的随机接入反馈，从而获得不同TRP或不同小区的时间差值，进而进行定位计算。

情况1：两步随机接入过程。
在同步信号块的随机接入过程包括：两步随机接入过程的情况下，在终端设备发送前导码的同时，终端设备通过MsgA(即消息A)的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)发送通知消息。PRACH和PUSCH称为MsgA。

其中，通知消息包括：前导码的发送功率值、定位参考信号测量结果值和终端设备的标识信息中的至少一种。
定位参考信号测量结果值是终端设备接收下行定位参考信号(Positioning Reference Signal，PRS)后，对定位参考信号进行测量得到的结果值。定位参考信号测量结果值包括但不限于：信号强度测量值、时间测量值和角度测量值中的至少一种。时间测量值包括但不限于：RSTD和Rx–Tx time difference中的至少一种；信号强度测量值包括但不限于：RSRP，RSRQ和RSSI中的至少一种；角度测量值包括但不限于：AoD和AoA中的至少一种。
终端设备的标识信息用于告知网络设备是哪个终端设备发送的定位用途参考信号，终端设备的标识信息可以记为UE ID，UE ID可以是：C-RNTI、临时C-RNTI、RA-RNTI、NAS UE ID中的一种。
情况2：四步随机接入过程。
在同步信号块的随机接入过程包括：四步随机接入过程的情况下，终端设备通过Msg3的PUSCH发送通知消息。
相应地，网络设备通过Msg3(即消息3)的PUSCH接收通知消息。
其中，通知消息包括：前导码的发送功率值、定位参考信号测量结果值和终端设备的标识信息中的至少一种。
定位参考信号测量结果值是终端设备接收下行定位参考信号后，对定位参考信号进行测量得到的结果值。定位参考信号测量结果值包括但不限于：信号强度测量值、时间测量值和角度测量值中的至少一种。时间测量值包括但不限于：RSTD和Rx–Tx time difference中的至少一种；信号强度测量值包括但不限于：RSRP，RSRQ和RSSI中的至少一种；角度测量值包括但不限于：AoD和AoA中的至少一种。
终端设备的标识信息用于告知网络设备是哪个终端设备发送的定位用途参考信号，终端设备的标识信息可以记为UE ID，UE ID可以是：C-RNTI、临时C-RNTI、RA-RNTI、NAS UE ID中的一种。
综上所述，本实施例提供的方法，终端设备通过两步随机接入过程和四步随机接入过程中的任意一种，在PUSCH信道上发送通知消息，通知消息可以进一步通知网络设备定位相关信息，提高了定位的准确性。
在基于图6的可选实施例中，终端设备在根据n个定位随机接入资源进行定位用途参考信号的发送之后，终端设备的状态为下面情况中的任意一种：
