具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。

图1是根据本公开的实施例示出的一种信号收发方法的示意流程图。本实施例所示的信号收发方法可以适用于第一终端，所述第一终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述第一终端可以作为用户设备与网络侧设备，所述网络侧设备包括但不限于基站、核心网，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。
如图1所示，所述信号收发方法可以包括以下步骤：
在步骤S101中，在第一频率上收发用于设备发现的发现信号；
在步骤S102中，在第二频率上收发用于对设备发现进行控制的发现控制信号；
其中，所述第一频率和所述第二频率不同。
需要说明的是，上述步骤S101和步骤S102的执行顺序是不分先后的，可以根 据需要设置执行顺序，还可以同时执行。
在一个实施例中，在发现过程中，第一终端可以作为被发现终端发送发现信号，例如以广播的方式发送发现信号，以使第一终端附近的第二终端(第一终端以外的终端)可以发现第一终端。第一终端也可以作为发现终端接收发现信号，例如接收第一终端附近的第二终端广播的发现信号，从而发现第二终端。进而第一终端和第二终端可以进行通信，例如可以通过通信确定第一终端和第二终端之间的相对测距。
以下主要在第一终端作为被发现终端，第二终端作为发现终端的情况下，对本公开的实施例进行示例性说明。第一终端和第二终端并非特指某些终端，而是指任意两个不同的终端。
在一个实施例中，在发现信号中可以携带有能够表征第一终端身份的信息，以及第一终端进行设备发现所要进行业务的信息，例如在发现信号中携带有第一终端的标识，以及第一终端触发设备发现的应用的标识。
第二终端在接收到发现信号后，根据第一终端的标识可以确定第一终端需要进行通信，根据应用的标识可以确定第一终端需要进行何种业务，进而第二终端可以根据自身需要确定是否与第一终端通信。若确定与第一终端通信，通信时可以采用直接通信方式或间接通信方式，其中，直接通信方式包括但不限于基于直连链路sidelink通信，间接通信方式包括但不限于通过网络侧设备(例如基站、核心网)通信。
在一个实施例中，为了使得发现过程顺利进行，第一终端还可以发送发现控制信号，例如向网络侧设备发送发现控制信号，以与网络侧设备协商在发现过程中第一终端所使用的标识。
在相关技术中，发现信号和发现控制信号在相同频率上收发，但是对于发现信号和发现控制信号而言，两者的内容和功能存在很大区别，两者所需满足的传输要求也有所不同，在同一频率上收发发现信号和发现控制信号，不便于对两者的传输进行控制，并且可能导致一个信号的收发受到另一个信号的干扰。例如多个终端中有的终端发送发现信号，有的终端发送发现控制信号，若第一终端在同一频率上接收发现信号和发现控制信号，可能出现发现信号和发现控制信道同时到达的情况，而第一终端同一时刻只能接收一个信号，从而导致第一终端舍弃掉同时到达的多个信号中的一个信号。
根据本公开的实施例，可以在第一频率上收发发现信号，在第二频率上收发发 现控制信号，从而实现了在不同频率上分别收发发现信号和发现控制信号。据此，便于对发现信号和发现控制信号的传输进行分别控制，并且可以在一定程度上避免其中一个信号的收发受到另一个信号的干扰。
在一个实施例中，所述发现信号基于直接通信技术收发。例如可以基于sidelink(直连链路)、V2X(vehicle to everything，车与外界通信)、WiFi direct(直连)、UWB(Ultra Wide Band，超带宽)、蓝牙等方式收发发现信号。基于直接通信技术收发发现信号，可以确保被发现终端发出发现信号后，发现终端能够尽快接收到发现信号。
在一个实施例中，所述发现信号为物理层的第一信号序列。其中，第一信号序列包括但不限于Zadoff-Chu序列。
在一个实施例中，所述第一信号序列用于携带被发现终端在L1标识的部分或全部。第一信号序列自身可以携带一些信息，例如可以携带被发现终端在L1标识的部分或全部，具体可以携带的信息量可以取决于信号序列的数量。
需要说明的是，在本公开所有实施例中，L1是指层1，主要包括物理层，L2是指层2，主要包括数据链路层。
在一个实施例中，所述第一信号序列具有第一负载(payload)，所述第一负载用于携带以下至少之一：进行设备发现对应应用(application)的标识、被发现终端的标识、被发现终端在L1的标识、被发现终端在L2的标识。
通过为第一信号序列添加第一负载，可以通过第一负载携带更多信息。例如基于应用的标识，第二终端可以确定第一终端进行设备发现所要进行的业务，也即该应用对应的业务，据此可以确定是否要与第一终端通信。
其中，被发现终端的标识可以是终端的唯一标识，例如IMSI(International Mobile Subscriber Identity，国际移动用户识别码)，TMSI(Temporary Mobile Subscriber Identity，临时移动用户识别码)，S-TMSI，C-RNTI(Radio Network Tempory Identity，无线网络临时标识)，I-RNTI，也可以是网络侧设备为被发现终端配置的，在指定时段内和/或指定区域内的唯一临时标识。
在一个实施例中，所述第一负载为物理层信息、或控制面数据包、或用户面数据包，例如可以是MAC PDU(介质访问控制层协议数据单元)。
在一个实施例中，所述发现信号为控制面数据包或用户面数据包。
其中，控制面数据包包括但不限于RRC(无线接入控制层)消息、NAS(非接入层)消息、ProSe(邻近业务)消息等专用控制协议消息，例如发现请求消息、发现响应消息。在发现信号为控制面数据包或用户面数据包的情况下，发现信号仍然作为普通数据(而非控制信息)在所述第一频率上发送。
在一个实施例中，所述在第二频率上收发用于对设备发现进行控制的发现控制信号包括：在所述第二频率上将所述发现控制信号发送至网络侧设备。
第一终端可以将发现控制信号发送给网络侧设备，基于发现控制信号的具体功能，发现控制信号中所携带的内容可以有所不同。例如发现控制信号仅用于与网络侧设备协商用于控制设备发现过程的信息，那么可以不必携带第二终端的标识，网络侧设备也不必将发现控制信息发送给第二终端；而若发现控制信号用于与第二终端协商用于控制设备发现过程的信息，那么需要携带第二终端的标识，网络侧设备需要进一步将发现控制信息发送给第二终端。
其中，用于控制设备发现过程的信息，例如可以是被发现终端在设备发现过程中所用的标识、设备发现过程所用的资源、设备发现过程后通信的资源等。
在一个实施例中，所述发现控制信号用于请求所述网络侧设备为被发现终端分配标识。网络侧设备接收到该发现控制信号后，一方面可以为第一终端分配标识，以供终端在设备发现过程中使用，另一方面还可以选择将分配给第一终端的标识告知第二终端，或者第二终端可以预先得知该标识。
在一个实施例中，所述发现控制信号中还携带有请求所述网络侧设备为被发现终端分配标识的原因。网络侧设备可以基于该原因为第一终端分配标识，例如基于不同的原因可以为第一终端分配不同的标识，所述原因包括但不限于进行设备发现、需要被分配用户设备标识等。
在一个实施例中，所述发现控制信号携带在无线接入控制消息中或携带在非接入层消息中。
在一个实施例中，所述发现控制信号中携带有在设备发现过程中被发现终端的标识，与被发现终端的应用层标识之间的映射关系。
其中，被发现终端的标识可以是用户设备标识，也可以是被发现终端的L1标识、L2标识等。被发现终端的应用层标识，可以对应于被发现终端中触发设备发现的应用的标识，网络侧设备或者发现终端在接收到携带该映射关系的发现控制信号后， 只需接收被发现终端的标识和被发现终端的应用层标识中的一个标识，就能够根据映射关系确定另一个标识。
在一个实施例中，所述第一频率为授权频段上的频率，或非授权频段上的频率。由于发现信号一般所需通信资源较少，所以可以使用非授权频段发送，对于非授权频段占用的时长也会相对较少，不易影响其他需要使用非授权频段设备的通信。其中，为了使用非授权频段，需要对非授权频段进行LBT(Listen Before Talk，先听后说)。
图2是根据本公开的实施例示出的另一种信号收发方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，在第三频率上收发用于确定终端之间距离的测距信号；
在步骤S202中，在第四频率上收发用于对确定所述距离进行控制的测距控制信号；
其中，所述第三频率和所述第四频率不同。
在一个实施例中，在第一终端被第二终端发现后，或者发现第二终端后，若第一终端和第二终端确定需要进行基于测距的服务，那么可以进一步进行测距。
在测距过程中，第一终端可以在第三频率上收发用于确定终端之间距离的测距信号，以及在第四频率上收发用于对确定所述距离进行控制的测距控制信号。
由于第三频率和第四频率不同，从而实现了在不同频率上分别收发测距信号和测距控制信号。据此，便于对测距信号和测距控制信号的传输进行分别控制，并且可以在一定程度上避免其中一个信号的收发受到另一个信号的干扰。
图3是根据本公开的实施例示出的一种信号接收方法的示意流程图。本实施例所示的信号接收方法可以适用于网络侧设备，所述网络侧设备可以与终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述网络侧设备包括但不限于基站、核心网，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。
如图3所示，所述信号接收方法可以包括以下步骤：
在步骤S301中，在第一频率接收第一终端发送的用于设备发现的发现信号；
在步骤S302中，在第二频率接收第一终端发送的用于对设备发现进行控制的发现控制信号；
其中，所述第一频率和所述第二频率不同。
在一个实施例中，第一终端可以在第一频率上发送发现信号，在第二频率上发送发现控制信号，相应地，网络侧设备可以在第一频率接收发现信号，在第二频率上接收发现控制信号。
需要说明的是，上述步骤S301和步骤S302，网络侧设备可以选择性执行，并非两步都要执行，例如可以只执行步骤S302接收发现控制信号，而不接收发现信号。
由于第一频率和第二频率不同，实现了在不同频率上分别接收发现信号和发现控制信号。据此，便于对发现信号和发现控制信号的传输进行分别控制，并且可以在一定程度上避免其中一个信号的接收受到另一个信号的干扰。
在一个实施例中，所述方法还包括：在所述第一频率上将所述发现信号发送至第二终端。网络侧设备在接收到发现信号后，可以在第一频率上将发现信号发送给第二终端，以供第二终端发现第一终端。
在一个实施例中，所述方法还包括：在所述第二频率上向所述第一终端反馈所述发现控制信号的响应信号。第一终端可以在第二频率上向网络侧设备发送发现控制信号，以与网络侧设备协商用于控制设备发现过程的信息，网络侧设备在接收到发现控制信号后，可以向第一终端反馈发现控制信号的响应信号，响应信号中可以携带有协商结果，例如为第一终端分配的在设备发现过程中所用的临时标识。
图4是根据本公开的实施例示出的一种信号收发方法的示意流程图。本实施例所示的信号收发方法可以适用于第一终端，所述第一终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述第一终端可以作为用户设备与网络侧设备，所述网络侧设备包括但不限于基站、核心网，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。
如图4所示，所述信号收发方法可以包括以下步骤：
在步骤S401中，在第三频率上收发用于确定终端之间距离的测距信号；
在步骤S402中，在第四频率上收发用于对确定所述距离进行控制的测距控制信号；
其中，所述第三频率和所述第四频率不同。
需要说明的是，上述步骤S401和步骤S402的执行顺序是不分先后的，可以根 据需要设置执行顺序，还可以同时执行。
在一个实施例中，在测距过程中，第一终端可以作为测距的起始终端，第二终端可以作为测距的目标终端，反之，第二终端可以作为测距的起始终端，第一终端可以作为测距的目标终端，其中，起始终端是指发起测距的终端，可以向目标终端发送测距信号。
以下主要在第一终端作为起始终端，第二终端作为目标终端的情况下，对本公开的实施例进行示例性说明。第一终端和第二终端并非特指某些终端，而是指任意两个不同的终端。
在一个实施例中，在测距信号中可以携带有能够表征第一终端身份的信息，例如第一终端在L1或L2的标识。
第二终端在接收到测距信号后，可以确定需要与第一终端进行测距，进而可以基于相应的测距算法进行测距。其中，测距算法包括但不限于单边测距、双边测距。
基于单边测距，第一终端向第二终端发送测距信号，第二终端接收到该测距信号后向第一终端发送响应信号(也可以是一个测距信号)。第一终端可以根据从发送测距信号到接收到响应信号的时长，以及第二终端从接收到测距信号到向第一终端发送响应信号的时长，来计算测距信号在第一终端和第二终端之间的往返时间，进而基于往返时间和信号的传播速度(例如光速)来计算第一终端和第二终端的距离。其中，测距信号和响应信号的接收和发送，都可以在第三频率上进行。
需要说明的是，本公开所有实施例中的测距信号可以是一个或多个参考信号。
基于双边测距，第一终端可以在约定的时间窗内向第二终端发送第一测距信号，第二终端在约定的时间窗口内接收第一测距信号；
第二终端接收到第一测距信号后，向第一终端回复第二测距信号，其中，可以计算第二终端接收到第一测距信号，到向第一终端回复第二测距信号的时间间隔作为第一时间信息；
第一终端接收到第二测距信号后，向第二终端回复第三测距信号，其中，可以计算第一终端接收到第二测距信号，到向第二终端回复第三测距信号的时间间隔作为第二时间信息，以及计算第一终端从发送第一测距信号，到接收到第二测距信号的时间间隔作为第三时间信息；
第二终端接收到第三测距信号后，可以计算从发送第二测距信号，到接收到第三测距信号的时间间隔作为第四时间信息。
若需要第一终端计算测距结果，第二终端可以将第一时间信息和第四时间信息发送给第一终端；若需要第二终端计算测距结果，第一终端可以将第二时间信息和第三时间信息发送给第二终端。第一终端和/或第二终端可以根据第一时间信息、第二时间信息、第三时间信息和第四时间信息计算第一终端和第二终端之间的往返时间，进而基于往返时间和信号的传播速度(例如光速)来计算第一终端和第二终端的距离。
在一个实施例中，为了使得测距过程顺利进行，第一终端还可以发送测距控制信号，例如向网络侧设备发送测距控制信号，以与网络侧设备协商在测距过程中第一终端所使用的标识，也可以向第二终端发送测距控制信号，以发送测距结果，指示测距失败等。
在相关技术中，测距信号和测距控制信号在相同频率上收发，但是对于测距信号和测距控制信号而言，两者的内容和功能存在很大区别，两者所需满足的传输要求也有所不同，在同一频率上收发测距信号和测距控制信号，不便于对两者的传输进行控制，并且可能导致一个信号的收发受到另一个信号的干扰。例如多个终端中有的终端发送测距信号，有的终端发送测距控制信号，若第一终端在同一频率上接收测距信号和测距控制信号，可能出现测距信号和测距控制信道同时到达的情况，而第一终端同一时刻只能接收一个信号，从而导致第一终端舍弃掉同时到达的多个信号中的一个信号。
根据本公开的实施例，可以在第三频率上收发测距信号，在第四频率上收发测距控制信号，从而实现了在不同频率上分别收发测距信号和测距控制信号。据此，便于对测距信号和测距控制信号的传输进行分别控制，并且可以在一定程度上避免其中一个信号的收发受到另一个信号的干扰。
需要说明的是，第三频率和上述实施例中的第一频率可以相同，也可以不同；第四频率和上述实施例中的第二频率可以相同，也可以不同，具体可以根据需要设置。
在一个实施例中，所述测距信号基于直接通信技术收发。例如可以基于sidelink(直连链路)、V2X(vehicle to everything，车与外界通信)、WiFi direct(直连)、UWB(Ultra Wide Band，超带宽)、蓝牙等方式收发测距信号。基于直接通信技术收发测距信号，可以确保起始终端发出测距信号后，目标终端能够尽快接收到测距信号。
在一个实施例中，所述测距信号为物理层的第二信号序列。其中，第二信号序列包括但不限于Zadoff-Chu序列。
在一个实施例中，所述第二信号序列用于携带有发送所述测距信号的终端在L1标识的部分或全部。第一信号序列自身可以携带一些信息，例如可以携带发送所述测距信号的终端在L1标识的部分或全部，具体可以携带的信息量可以取决于信号序列的数量。
在一个实施例中，所述第二信号序列具有第二负载，所述第二负载用于携带以下至少之一：
发送所述测距信号的终端的标识、发送所述测距信号的终端在L1的标识、发送所述测距信号的终端在L2的标识、基于双边测距的第一时间信息、基于双边测距的第二时间信息、基于双边测距的第三时间信息；
其中，所述第一时间信息表征目标终端接收到起始终端的第一测距信号，到向起始终端回复第二测距信号的时间间隔；所述第二时间信息表征起始终端接收到所述第二测距信号，到所述目标终端回复第三测距信号的时间间隔；所述第三时间信息表征所述起始终端从发送所述第一测距信号，到接收到所述第二测距信号的时间间隔。
通过为第一信号序列添加第一负载，可以通过第一负载携带更多信息。其中，发送所述测距信号的终端的标识可以是终端的唯一标识，例如IMSI(International Mobile Subscriber Identity，国际移动用户识别码)，TMSI(Temporary Mobile Subscriber Identity，临时移动用户识别码)，S-TMSI，C-RNTI(Radio Network Tempory Identity，无线网络临时标识)，I-RNTI，也可以是网络侧设备为发送所述测距信号的终端配置的，在指定时段内和/或指定区域内的唯一临时标识。
在双边测距中，当第二终端接收到第三测距信号后，可以计算从发送第二测距信号，到接收到第三测距信号的时间间隔作为第四时间信息。在第二终端接收到第三测距信号之前，第一终端和第二终端之间仍会交互测距信号，在第二终端接收到第三测距信号之前，第一终端和第二终端之间就不会交互测距信号了。
而第一时间信息、第二时间信息、第三时间信息都是在第二终端接收到第三测距信号之前就能计算得到的，因此可以携带在测距信号的负载中发送，而第四时间信息则是在第二终端接收到第三测距信号之后计算得到的，因此可以不通过测距信号的负载中发送，而通过测距控制信息发送。
在一个实施例中，所述第二负载为物理层信息、或控制面数据包、或用户面数据包，例如可以是MAC PDU(介质访问控制层协议数据单元)。
在一个实施例中，所述在第四频率上收发用于对确定所述距离进行控制的测距控制信号包括：在所述第四频率上将所述测距控制信号发送至网络侧设备或第二终端，其中，所述距离为所述第一终端与所述第二终端之间的距离。
第一终端可以将测距控制信号发送给网络侧设备或第二终端，基于测距控制信号的具体功能，测距控制信号可以被发送至网络侧设备获第二终端。例如测距控制信号用于与网络侧设备协商，那么可以将测距控制信号发送至网络侧设备；例如测距控制信号用于携带测距结果，那么可以将测距控制信号发送至第二终端。
在一个实施例中，所述测距控制信号包括以下至少之一：测距请求信息、测距响应信息、测距失败信息、测距结果信息。这些测距控制信息可以使用Uu接口发送，也可以根据需要选择其他接口发送。
在一个实施例中，所述测距请求信息中携带有以下至少之一：
接收所述测距请求信息的终端的标识(也即发送所述测距信号的终端的标识，以供网络侧设备基于该标识将请求信息发送给对应终端)、发送所述测距请求信息的终端的测距能力信息(例如所支持的带宽、天线数量等)、测距会话标识、测距信号在L1的标识、测距信号在L2的标识、测距带宽、接收所述测距信号的时间信息(可以是起始终端接收测距信号的时间窗、也可以是目标终端接收测距信号的时间窗)。
在一个实施例中，所述测距响应信息中携带有以下至少之一：
接收所述测距响应信息的终端的标识、发送所述测距响应信息的终端的测距能力信息(例如所支持的带宽、天线数量等)、测距信号在L1的标识、测距信号在L2的标识、测距带宽、接收所述测距信号的时间信息(可以是起始终端接收测距信号的时间窗、也可以是目标终端接收测距信号的时间窗)。
在一个实施例中，所述测距失败信息中携带有以下至少之一：
接收所述测距失败信息的终端的标识、测距会话标识、测距信号质量、测距失败原因(例如测距信号收发时间早于测距响应信息的接收时间、未收到测距信号、未收到测距响应信息等)。
其中，测距失败可以由以下一种或多种情况导致：测距信号收发时间早于测距 响应信息接收时间，在约定接收测距信号的时段内未收到测距信号，在约定接收测距响应信息的时段内未收到测距响应信息，测距信号质量小于门限值。
在一个实施例中，所述测距结果信息中携带有以下至少之一：
基于单边测距的结果信息、基于双边测距的结果信息、到达角信息、离开角信息、所述距离。
在一个实施例中，所述基于双边测距的结果信息包括以下至少之一：
基于双边测距的第一时间信息、基于双边测距的第二时间信息、基于双边测距的第三时间信息、基于双边测距的第四时间信息；
其中，所述第一时间信息表征目标终端接收到起始终端的第一测距信号，到向起始终端回复第二测距信号的时间间隔；所述第二时间信息表征起始终端接收到所述第二测距信号，到所述目标终端回复第三测距信号的时间间隔；所述第三时间信息表征所述起始终端从发送所述第一测距信号，到接收到所述第二测距信号的时间间隔；所述第四时间信息表征所述目标终端从发送所述第二测距信号，到接收到所述第三测距信号的时间间隔。
在双边测距中，当第二终端接收到第三测距信号后，可以计算从发送第二测距信号，到接收到第三测距信号的时间间隔作为第四时间信息。在第二终端接收到第三测距信号之前，第一终端和第二终端之间仍会交互测距信号，在第二终端接收到第三测距信号之前，第一终端和第二终端之间就不会交互测距信号了。
而第一时间信息、第二时间信息、第三时间信息都是在第二终端接收到第三测距信号之前就能计算得到的，因此可以选择携带在测距信号的负载中发送，也可以选择携带在测距控制信息的结果信息中发送；而第四时间信息则是在第二终端接收到第三测距信号之后计算得到的，因此可以不通过测距信号的负载中发送，而通过测距控制信息发送。
在一个实施例中，所述第三频率为授权频段上的频率，或非授权频段上的频率。由于测距信号(一般是一个参考信号)所需通信资源较少，所以可以使用非授权频段发送，对于非授权频段占用的时长也会相对较少，不易影响其他需要使用非授权频段设备的通信。其中，为了使用非授权频段，需要对非授权频段进行LBT(Listen Before Talk，先听后说)。
图5是根据本公开的实施例示出的另一种信号收发方法的示意流程图。如图5 所示，所述方法还包括：
在步骤S501中，在第一频率上收发用于设备发现的发现信号；
在步骤S502中，在第二频率上收发用于对设备发现进行控制的发现控制信号；
其中，所述第一频率和所述第二频率不同。
在一个实施例中，在进行测距之前或之后，若需要进行发现操作，第一终端可以在第一频率上收发用于设备发现的发现信号，在第二频率上收发用于对设备发现进行控制的发现控制信号。
由于第一频率和第二频率不同，从而实现了在不同频率上分别收发发现信号和发现控制信号。据此，便于对发现信号和发现控制信号的传输进行分别控制，并且可以在一定程度上避免其中一个信号的收发受到另一个信号的干扰。
图6是根据本公开的实施例示出的一种信号接收方法的示意流程图。本实施例所示的信号接收方法可以适用于网络侧设备，所述网络侧设备可以与终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述网络侧设备包括但不限于基站、核心网，所述基站包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。
如图6所示，所述信号接收方法可以包括以下步骤：
在步骤S601中，在第三频率接收第一终端发送的用于确定终端之间距离的测距信号；
在步骤S602中，在第四频率接收第一终端发送的用于对确定所述距离进行控制的测距控制信号；
其中，所述第三频率和所述第四频率不同。
在一个实施例中，第一终端可以在第三频率上发送测距信号，在第四频率上发送测距控制信号，相应地，网络侧设备可以在第三频率接收测距信号，在第四频率上接收测距控制信号。
需要说明的是，上述步骤S601和步骤S602，网络侧设备可以选择性执行，并非两步都要执行，例如可以只执行步骤S602接收测距控制信号，而不接收测距信号。
由于第三频率和第四频率不同，实现了在不同频率上分别接收测距信号和测距控制信号。据此，便于对测距信号和测距控制信号的传输进行分别控制，并且可以在 一定程度上避免其中一个信号的接收受到另一个信号的干扰。
在一个实施例中，所述方法还包括：在所述第三频率上将所述测距信号发送至第二终端。网络侧设备在接收到测距信号后，可以在第三频率上将测距信号发送给第二终端，以供第二终端与第一终端进行测距。
