为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
目前的蜂窝网络，包括5G网络，仅用于通信。但是其实蜂窝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可以考虑不只是用于通信和数据传输，还可以用于感知信息的获取。
可以考虑在B5G(Beyond 5th Generation，超5G)网络中支持感知能力，通过增加感知控制网元(Sensing Function)及相应流程在网络中支持感知功能。图3示出了一种可能的控制接入网设备或者UE进行UE级别感知操作的流程图。图4示出了一种可能的控制接入网设备或者UE进行区域级别感知操作的流程图。
如图3和图4所示，当应用将针对目标UE或目标区域的感知请求发送到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和/或辅助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。
通信和感知两个功能融合的融合，可以称为通感一体化，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。
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)、信道状态信息测量参考信号(Channel State Information Reference Signal，CSI-RS)、相位跟踪参考信号(Phase-tracking Reference Signal，PTRS)、定位参考信号(Positioning Reference Signal，PRS)等信号，执行感知行为，不引入过多的空口增强。
上述相关技术中，针对目标UE或目标区域的感知，核心网的感知控制网元(SF)或AMF负责选择合适的接入网设备(gNB)或者辅助UE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的时频位置时需要接入网设备或UE上报与感知信号的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。
本申请实施例提供的方案，主要用于解决上述问题中的至少一个。
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
图5是根据本申请一实施例的信号传输方法的示意性流程图，该方法包括以下内容 的至少部分内容。
S110，第一接入网设备向第二接入网设备发送感知请求消息；
其中，感知请求消息包括感知信号配置信息，感知信号配置信息用于第二接入网设备接收感知信号。
可选地，感知请求消息可以用于请求/指示第二接入网设备辅助完成感知过程。具体地，感知请求消息可以用于请求/指示第二接入网设备接收感知信号，以基于感知信号得到感知数据。
与上述方法相应地，本申请实施例还提供一种信息传输方法，如图6所示，该方法包括：
S210，第二接入网设备接收来自第一接入网设备的感知请求消息；其中，感知请求消息包括感知信号配置信息；
S220，第二接入网设备基于感知信号配置信息接收感知信号。
据本申请实施例的方法，第一接入网设备可以与第二接入网设备之间直接协调感知信号的配置，即第一接入网设备确定感知信号配置信息，向用于辅助感知的第二接入网设备发送感知信号配置信息。因此，不需要核心网网元配置感知信号并将感知信号配置信息发送给第二接入网设备，从而也不需要将感知信号配置的辅助信息上报核心网网元，可以达到节省信令开销并降低时延的技术效果。
可选地，在本申请的实施例中，感知信号可以包括用于感知的参考信号，也可以称为感知参考信号。示例性地，感知信号可以包括SRS、DMRS、PTRS和PRS中的至少一个。
可选地，感知信号配置信息包括以下信息中的至少一个：
感知信号的类型；
感知信号的时域资源位置；
感知信号的频域资源位置；
感知信号的开始时间；
感知信号的结束时间。
例如，感知信号配置信息包括感知信号的频域资源位置，则第二接入网设备可以在该频域资源位置上接收感知信号。又如，感知信号配置信息包括感知信号的开始时间和结束时间，则第二接入网设备可以在该开始时间和结束时间之间，接收感知信号。通过交互感知信号配置信息，使得第二接入网设备可以准确接收感知信号。
可选地，在第二接入网设备基于感知信号配置信息接收感知信号之前，上述信息传输方法还包括：
第二接入网设备向第一接入网设备发送感知请求响应消息。
示例性地，该感知请求响应消息用于指示可以进行感知信号的发送。
针对不同的应用场景，可以由不同的发送端发送感知信号。例如，在针对区域的基站间感知链路中，可以由第一接入网设备向目标区域发送感知信号，以使第二接入网设备能够接收目标区域反射的感知信号。又例如，在针对UE的空口上行感知链路中，可以由目标终端发送感知信号，以使第二接入网设备接收来自目标终端的感知信号。
示例性地，感知请求响应消息用于指示第一接入网设备向目标区域发送感知信号。相应地，上述信息传输方法还包括：第一接入网设备在接收到来自第二接入网设备的感知请求响应消息的情况下，向目标区域发送感知信号。
其中，目标区域可以理解为待感知的区域。通过对目标区域发送感知信号，第二接入网设备可以接收到目标区域发射的感知信号，从而可以得到对应的感知数据，例如通过对感知信号进行测量得到感知数据。
示例性地，感知请求响应消息用于指示第一接入网设备向终端发送激活信息，该激活信息用于指示终端激活感知信号配置信息，以基于感知信号配置信息发送感知信号。其中，该终端可以包括待感知的终端，即目标终端。
可选地，终端上的感知信号配置信息可以是预先由第一接入网设备配置的。也就是说，上述信息传输方法还可以包括：第一接入网设备向终端发送感知信号配置信息；其中，感知信号配置信息还用于终端发送感知信号。
相应地，本申请实施例还提供一种信息传输方法，该方法可选地可以用于上述终端，即应用于感知的目标终端，如图7所示，该方法包括：
S310，终端接收来自第一接入网设备的感知信号配置信息；
S320，终端基于感知信号配置信息发送感知信号。
可选地，上述感知信号配置信息可以由无线资源控制(Radio Resource Control，RRC)专用信令承载。
由于第一接入网设备向终端发送感知信号配置信息，因此，也不需要核心网网元配置感知信号并将感知信号配置信息发送给终端，且不需要将感知信号配置的辅助信息上报核心网网元，达到节省信令开销并降低时延的技术效果。
可选地，上述信息传输方法还包括：第一接入网设备在接收到来自第二接入网设备的感知请求响应消息的情况下，向终端发送激活信息，其中，激活信息用于指示终端激活感知信号配置信息，基于感知信号配置信息发送感知信号。
相应地，上述步骤S320，终端基于感知信号配置信息发送感知信号，可以包括：
终端在接收到来自第一接入网设备的激活信息的情况下，激活感知信号配置信息，并基于感知信号配置信息发送感知信号。
可选地，对于第二接入网设备，上述信息传输方法还可以包括：
第二接入网设备基于感知信号，获得感知数据，并向第一接入网设备发送感知数据。
示例性地，第二接入网设备可以接收感知的目标区域反射的感知信号，基于该感知信号得到针对目标区域的感知数据。或者，第二接入网设备可以接收感知的目标终端所发送的感知信号，得到针对目标终端的感知数据。可选地，第二接入网设备可以通过对感知信号进行测量，得到目标终端或目标区域的感知数据。
相应地，对于第一接入网设备，上述信息传输方法还可以包括：
第一接入网设备接收来自第二接入网设备的感知数据，并向核心网设备发送感知数据。
也就是说，第一接入网设备可以收集感知数据，并向核心网设备上报，以便于核心网设备向发起感知请求的应用功能反馈感知信息。
实际应用中，第二接入网设备的数量可以是一个或多个。也就是说，第一接入网设备可以向一个或多个第二接入网设备发送感知信号配置信息，从而使多个第二接入网设备辅助完成感知流程，提高感知的准确性。
可选地，感知流程可以由应用功能请求发起，应用功能向核心网设备发送感知请求，其中可以感知的目标区域或目标终端。核心网设备向第一接入网设备发送感知指令，以触发第一接入网设备确定感知信号配置信息，执行感知流程。其中，感知指令可以指示目标区域或目标终端的相关信息，还可以指示其他感知相关信息，例如感知类型、可用于辅助感知的第二接入网设备的标识等。
为了更清楚地理解本申请实施例的特点，下面结合具体的场景，提供两个具体的应用示例。
应用示例一：
本应用示例中，第一接入网设备为完成感知流程的主要基站(以下称主要gNB)。 第二接入网设备为辅助基站(以下称辅助gNB)。
如图8所示，在本应用示例中，具体实施过程如下：
步骤1：与目标区域相关的主要gNB接收核心网设备(AMF和/或SF)的感知指令，感知指令中可以包含感知类型，例如基站间(gNB-gNBs)感知、gNB回波感知等。可选地，感知指令中也可包含目标区域的信息，例如角度、高度等。
如果感知类型为gNB-gNBs感知，则感知指令中还包含辅助gNB标识(或标识列表)。
步骤2：在感知类型为gNB-gNBs感知的情况下，主要gNB通过Xn接口向所指示的辅助gNB发送感知请求消息，感知请求消息可以携带感知信号配置信息，如感知信号的类型(参考信号类型)、时频资源位置、开始/结束时间等。
步骤3：当主要gNB接收到辅助gNB的感知请求响应消息后，主要gNB向目标区域发射感知信号，辅助gNB测量目标区域反射的感知信号，产生感知数据。
步骤4：主要gNB接收一个或多个辅助gNB的感知数据，并反馈给核心网设备。
可见，通过引入基站间通过Xn接口发送感知请求消息，针对基站间感知场景，主要基站/辅助基站之间直接协调感知信号的发送和接收，以完成感知流程，不需要将感知信号配置的辅助信息上报给SF或AMF，节省信令开销并降低时延。
应用示例二：
本应用示例中，第一接入网设备为感知的目标UE的服务基站(以下称服务gNB)。第二接入网设备为辅助gNB。
如图9所示，在本应用示例中，具体实施过程如下：
步骤1：目标UE所在的服务gNB接收核心网设备(AMF和/或SF)的感知指令，感知指令消息中可以指示感知类型，例如空口上行感知(UE-gNB上行感知)。
如果感知类型为UE-gNB上行感知，则感知指令中还包含参与感知的UE标识、辅助gNB标识。
步骤2：在感知类型为UE-gNB上行感知的情况下，服务gNB决定目标UE的上行感知参考信号资源，并向目标UE发送感知信号配置信息。
可选地，该配置信息可承载于RRC专用信令
步骤3：在感知类型为UE-gNB上行感知的情况下，服务gNB根据辅助gNB标识通过Xn接口向所指示的辅助gNB发送感知请求消息。感知请求消息可以携带感知参考信号配置信息，如感知信号的类型、感知信号的时频资源位置、开始/结束时间等。
步骤4：当服务gNB接收到辅助gNB的感知请求响应消息后，指示目标UE激活感知信号配置信息，发送上行感知信号。辅助gNB测量感知信号，产生感知数据。
步骤5：服务gNB接收一个或多个辅助gNB的感知数据，并反馈给核心网设备。
可见，通过引入基站间通过Xn接口发送感知请求消息，针对空口上行感知场景，服务基站/辅助基站之间直接协调感知信号的发送和接收，以完成感知流程，不需要将感知信号配置的辅助信息上报给SF或AMF，节省信令开销并降低时延。
