相关技术中，B5G网络中支持感知能力，可以通过增加感知控制网元(Sensing Function，SF)在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)网络中实现感知功能。当应用将针对目标终端的感知请求发送到3GPP网络的核心网设备时，核心网设备通过SF或者接入和移动性管理功能(Access and Mobility Management Function，AMF)选择正确的接入网设备，或者由辅助终端设备执行感知相关操作，并配置感知参考信号的时频位置。

下面对于侧行链路(Sidelink，SL)进行说明。
设备到设备(Device to Device，D2D)通信是一种侧行链路传输技术，与传统的蜂窝系统中通信数据通过网络设备接收或者发送的方式不同，车联网系统采用终端设备到终端设备直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)定义了两种传输模式，分别为模式A和模式B。
图1为本申请实施例提供的一种侧行链路传输中模式A的示意图，如图1所示，在模式A中，终端设备的传输资源是由网络设备分配的，终端设备根据网络设备分配的资源在侧行链路上进行数据的发送。网络设备可以为终端设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源。
图2为本申请实施例提供的一种侧行链路传输中模式B的示意图，如图2所示，在模式B中，车载终端在资源池中选取一个资源进行数据的传输。
应理解，在3GPP中，D2D分成了不同的阶段进行研究。
其中，邻近服务(Proximity based Service，ProSe)主要针对公共安全类的业务。
车用无线通信(vehicle to X，V2X)主要针对相对高速移动的车车、车人通信的业务。
可穿戴设备(FeD2D)主要面向是低移动速度以及低功率接入的场景。
新空口(New Radio，NR)在长期演进技术(Long Term Evolution，LTE)V2X的基础上，不局限于广播场景，进一步拓展到了单播和组播的场景。
类似于LTE V2X，NR V2X也会定义上述mode-1和mode-2两种资源授权模式。进一步地，用户可能处在一个混合的模式下，即既可以使用mode-1进行资源的获取，又同时可以使用mode-2进行资源的获取。该资源获取通过侧行链路授权的方式指示，即侧行链路授权指示相应的物理侧边链路控制信道(PSCCH)与物理侧边链路共享信道(PSSCH)资源的时频位置。
此外，不同于LTE V2X，除了无反馈的终端设备自主发起的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)，NR V2X引入了基于反馈的HARQ重传，不限于单播通信，也包括组播通信。
下面对于Uu系统消息广播进行说明。
主系统模块(master information block，MIB)是通过映射到广播传输信道(Broadcast Channel，BCH)信道的广播逻辑信道(BCCH)进行广播的。系统信息块(System Information Block，SIB)1和OSI是通过映射到下行共享信道(DL-SCH)的BCCH进行广播的，在用户面上对层2协议，包括分组数据汇聚协议(PDCP)、无线链路控制协议(RLC)和媒体接入控制(MAC)层来说是透明的。即，说无线资源控制(Radio Resource Control，RRC)层在 进行了抽象语法符号1(ASN.1)编码以后直接发送给物理层来进行处理。
下面对于发现(Discovery)过程进行说明。
Model A discovery(“我在这里”)模型为参与Discovery的终端设备定义了通告终端和监测终端。
其中，通告终端通告某些信息，通告的信息可以被邻近的具有发现权限的终端设备使用。监测终端为监测在通告终端附近感兴趣的某些信息的终端。
在Model A discovery模型中，通告终端以预定义的发现间隔广播发现消息，对这些消息感兴趣的监控终端读取并处理该发现消息。该模型等效于“我在这里”，因为通告终端将广播有关其自身的信息。
Model B discovery(“谁在那里？”/“你在那里吗？”模型为参与Discovery的UE定义了发现终端和被发现终端。
其中，发现终端发送一个请求，其中包含有关它有兴趣发现什么的某些信息。被发现终端接收到请求消息后可以响应与发现者请求相关的一些信息。
在Model B discovery模型中，其等同于“谁在那里/你在那里吗”，因为发现终端发送有关其他希望从例如接收响应的终端的信息。该信息可以是一个群组对应的ProSe应用标识，该群组的成员可以响应。
下面对于5G网络的系统架构进行说明。
在5G网络的系统架构中，用户设备(User Equipment，UE)通过Uu口与接入网(Access Network，AN)进行接入层连接，交互接入层消息及无线数据传输，UE通过N1口与AMF进行非接入层(NAS)连接，交互NAS消息。AMF用于核心网中的移动性管理功能，会话管理网元(Session Management Function，SMF)用于核心网中的会话管理功能。AMF在对UE进行移动性管理之外，还负责将从会话管理相关消息在UE和SMF之间的转发。策略控制网元(Policy Control function，PCF)用于核心网中的策略管理功能，负责制定对UE的移动性管理、会话管理、计费等相关的策略。用户面功功能网元(User plane function，UPF)用于核心网中的用户面功能，通过N6接口与外部数据网络进行数据传输，通过N3接口与AN进行数据传输。
下面对于感知信号进行说明。
蜂窝网络(包括5G网络)所使用的无线电磁波信号不但可以用于无线数据传输和通信的用途，同时还具有环境感知能力，例如用户的动作或者手势识别、呼吸监测、终端移动速度测量、环境成像、天气监测等。因此，在未来的蜂窝网络还可以用于感知信息的获取。
相关技术中，在B5G网络中支持感知能力，通过增加感知控制网元(Sensing Function)及相应流程在3GPP网络中支持感知功能。当应用将针对目标终端的感知请求发送到3GPP网络的核心网，核心网通过感知控制网元或者AMF选择正确的接入网设备或者辅助UE，并触发进行感知相关的无线测量的能力，启动感知信息的测量并产生感知结果。
其中，通感一体化主要的无线感知场景有如下：
1)基站回波感知链路：基站发送感知信号并接收回波信号。
2)基站间感知链路：基站B接收基站A发送的感知信号。
3)空口上行感知链路：基站接收终端发送的感知信号。
4)空口下行感知链路：终端接收基站发送的感知信号。
5)终端回波感知链路：终端发送感知信号并接收回波信号。
6)终端间感知链路：终端B接收终端A发送的感知信号。
需要说明的是，在B5G通信感知一体化的初期阶段，考虑尽量复用现有的参考信号如信道探测参考信号(Sounding Reference Signal，SRS)、解调参考信号(Demodulation Reference Signal，DMRS)、信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)、相位跟踪参考信号(Phase Tracking Reference Signal，PTRS)、网络定位参考信号(Positioning Reference Signal，PRS)等执行感知行为，不引入过多的空口增强。
然而，针对目标终端或者目标区域的感知，SF或者AMF负责选择合适的接入网设备或者辅助终端执行感知相关操作，并配置感知参考信号的时频位置。由于SF或者AMF不掌握空口资源的信息，因此在配置感知信号时频位置时需要接入网设备或终端设备上报感知信号时频位置相关的辅助信息给AMF或SF，这增加了信令开销和时延。
为解决上述技术问题，本申请实施例提供一种通信方法及装置，通过目标终端向辅助终端发送感知信号的配置信息，从而由目标终端和辅助终端之间协调感知信号的发送和接收，无需将感知信号的配置信息上报给网络设备，从而降低了信令开销，并降低了时延。
下面对于本申请的应用场景进行举例说明。
图3为本申请实施例提供的一种通信方法的场景示意图。如图3所示，网络设备101可以向目标终端102发送感知指令来指示目标终端102执行侧行链路感知。若侧行链路感知的类型为设备间感知，目标终端102可以向至少一个辅助终端103发送感知请求，来传输感知信号的配置信息。随后，辅助终端103向目标终端102发送感知请求响应，来反馈辅助终端103是否支持待执行的侧行链路感知。随后，目标终端102和辅助终端103之间进行侧行链路感知，得到感知数据，并将感知数据发送给网络设备101。
其中，目标终端102和辅助终端103包括但不限于卫星或蜂窝电话、可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的PDA；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备可以指接入终端、用户设备(User Equipment，UE)、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。接入终端可以是蜂窝电话、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、个人数字处理(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PLMN中的终端设备等。
网络设备101可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备进行通信。可选地，该网络设备102可以是GSM系统或CDMA系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
下面以目标终端、辅助终端和网络设备等通信设备为例，以具体地实施例对本申请实施例的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图4为本申请实施例提供的一种通信方法的信令交互图。本申请实施例涉及的是如何进行侧行链路感知的过程。如图4所示，该方法包括：
S201、网络设备向目标终端发送感知指令，感知指令中包含有待执行的感知的类型。
在本申请中，当需要执行感知时，网络设备可以向目标终端发送感知指令，来指示待执行的感知的类型。
应理解，本申请实施例对于网络设备不做限制，在一些实施例中，网络设备可以包括AMF和/或SF。
应理解，本申请实施例对于感知的类型不做限制，在一些实施例中，感知的类型可以包括终端设备间感知(UE-UEs感知)、终端设备和接入网设备下行感知(UE-gNB下行感知)、终端设备和接入网设备上行感知(UE-gNB上行感知)和终端设备回波感知(UE回波感知)等。
应理解，终端设备间感知可以理解为侧行链路感知。
S202、若待执行的感知的类型为设备间感知，则目标终端向至少一个辅助终端发送感知请求。
在本步骤中，当目标终端接收到网络设备发送的感知指令后，可以对感知指令中指示待执行的感知的类型进行识别，若待执行的感知的类型为设备间感知，目标终端可以向至少一个辅助终端发送感知请求，而无需与网络设备通信。
其中，感知请求中包含有感知信号的配置信息。相应的，待执行的感知的类型为设备间感知，则感知信号具体可以包括侧行链路感知信号。
应理解，本申请实施例对于感知信号的配置信息的内容不做限制，在一 些实施例中，感知信号的配置信息包括以下至少一项：感知信号的类型、感知信号的起止时间、感知信号的频域资源位置。
其中，感知信号的类型可以为现有的参考信号，例如SSB、DMRS、CSI、PRS等，也可以为针对感知引入的新参考信号，本申请对此不做限制。
在一些可选的实施方式中，感知请求可以承载于侧行链路发现(SL discovery)消息中。该感知请求可以发送给一个或多个辅助终端，因此可以采用采用广播的方式进行发送。
需要说明的是，本申请实施例对于辅助终端的数量不做限制，可以为一个，也可以多个。相应的，可以有多个辅助终端接收到目标终端广播的感知请求，也可以只有一个辅助终端接收到目标终端广播的感知请求。
S203、辅助终端向目标终端发送感知请求响应，感知请求响应用于反馈至少一个辅助终端是否支持待执行的侧行链路感知。
在本步骤中，当辅助终端接收到感知请求后，辅助终端可以向目标终端发送感知请求响应，来反馈辅助终端是否支持待执行的感知。
其中，该感知请求响应中包含有至少一个辅助终端分别支持的感知信号的配置信息。
在一些实施例中，感知请求响应中的感知信号的配置信息可以包括辅助UE能够执行SL感知所建议的感知信号类型、时频位置等信息。通过感知信号的配置信息，可以在发送或接收感知信号时，选择合适的时频资源。
在一些可选的实施方式中，感知请求响应同样可以承载于SL discovery消息中。与感知请求不同的时，由于感知请求响应只发送给目标终端，因此可以采用单播的方式进行发送。
S204、目标终端根据感知请求响应确定感知数据。
在本步骤中，当目标终端接收到感知请求响应后，可以根据感知请求响应确定感知数据。
应理解，本申请实施例对于如何根据感知请求响应确定感知数据不做限制，可以由目标终端发送感知信号由辅助终端测量感知信号，也可以由辅助终端发送感知信号由目标终端测量感知信号。
示例性的，目标终端可以在感知请求响应指示的时频资源上向辅助终端发送感知信号。辅助终端接收到感知信号后，可以测量感知信号，生成感知数据。随后，辅助终端向目标终端发送感知数据。
示例性的，辅助终端可以在感知请求响应指示的时频资源上向目标终端发送感知信号。目标终端接收到感知信号后，可以测量感知信号，生成感知数据。
S205、目标终端向网络设备发送感知数据。
本申请中，引入目标终端向辅助终端发送感知信号请求消息，目标终端和辅助终端之间直接协调感知信号的发送和接收，以完成感知流程。基于此，本申请提供的通信方法不需要将感知信号的辅助信息上报给网络设备，可以 节省信令开销并降低时延。并且，辅助终端和目标终端无需在同一接入网设备下，甚至辅助终端可以处于接入网设备的信号覆盖范围外。
