第一方面，近几十年来，无线通信和雷达传感(Communication&Sensing，C&S)一直在并行发展，但交集有限。它们在信号处理算法、设备以及一定程度上的系统架构方面都有很多共性。近年来，这两个系统在共存、合作和联合设计上受到了越来越多研究人员的关注。
早期人们对通信系统和雷达系统共存的问题进行了广泛的研究，研究侧重是开发有效的干扰管理技术，使两个单独部署的系统能够在相互不干扰的情况下平稳运行。虽然雷达和通信系统可能在同一位置，甚至物理上集成，但它们在时间/频率域传输的是不同的两种信号。它们通过合作共享相同的资源，以最大限度地减少同时工作时对彼此之间的干扰。相应的措施包括波束赋形、合作频谱共享、主次频谱共享、动态共存等。然而有效的干扰消除通常对节点的移动性和节点之间的信息交换有着严格的要求，因此频谱效率的提高实际比较有限。由于共存系统中的干扰是由发射两个独立的信号引起的，因此很自然地会问，我们是否可以同时使用一个发射信号同时进行通信和雷达传感。雷达系统通常使用特别设 计的波形，如短脉冲和啁啾，能够实现高功率辐射和简化接收机处理。然而这些波形对雷达探测来说不是必需的，无源雷达或无源传感以不同的无线电信号作为感知信号就是一个很好的例子。
机器学习，特别是深度学习技术进一步促进了非专用无线电信号用于雷达传感的潜力。有了这些技术，传统雷达正朝着更通用的无线感知方向发展。这里的无线感知可以广泛地指从接收到的无线电信号中检索信息，而不是在发射机上调制到信号的通信数据。对于感知目标位置相关的无线感知，可以通过常用的信号处理方法，对目标信号反射时延、到达角(Angle of Arrival，AOA)、离开角(Angle of Departure，AOD)、多普勒等动力学参数进行估计；对于感知目标物理特征，可以通过测量设备、对象、活物的固有模式信号来实现。两种感知方式可以分别称为感知参数估计以及模式识别。在这个意义上，无线感知是指使用无线电信号的更通用的传感技术和应用。
通信感知一体化(Integrated Sensing and Communication，ISAC)有潜力将无线感知集成到大规模移动网络中，在这里称为感知移动网络(Perceptive Mobile Networks，PMNs)。PMN可以从目前的5G移动网络演变而来，有望成为一个无处不在的无线传感网络，同时提供稳定高质量的移动通信服务。它可以建立在现有移动网络基础设施之上，而不需要对网络结构和设备进行重大改变。它将释放移动网络的最大能力，并避免花费高昂基础设施成本去额外单独建设新的广域无线传感网络。随着覆盖范围的扩大，综合通信和传感能力有望实现许多新的应用。感知移动网络能够同时提供通信和无线感知服务，并且由于其较大的宽带覆盖范围和强大的基础设施，有可能成为一种无处不在的无线传感解决方案。其联合协调的通信和传感能力将提高我们社会的生产力，并有助于催生出大量现有传感器网络无法有效实现的新应用。利用移动信号进行被动传感的一些早期工作已经证明了它的潜力。例如基于全球移动通信系统(Global System for Mobile Communications，GSM)的无线电信号的交通监控、天气预报和降雨遥感。感知移动网络可以广泛应用于交通、通信、能源、精准农业和安全领域的通信和传感，而现有的解决方案要么不可行，要么效率低下。它还可以为现有的传感器网络提供互补的传感能力，具有独特的昼夜操作功能，能够穿透雾、树叶甚至固体物体。一些常见的感知业务如下表1所示：

但是，相关技术中的ISAC系统中，需要布局大量的无线感知信号发送端和无线感知信号接收端，以使无线感知信号接收端根据接收到的无线感知信号发送端发送的感知信号来确定感知测量量以及感知结果，而无线感知信号发送端和无线感知信号接收端包括耗电的射频链路，其包含振荡器、混频器和数字-模拟转换器等，这导致了感知设备的尺寸较大，且电池使用寿命较短，限制了ISAC中的感知设备的布局，进而使得ISAC系统的感知性能较低。
本申请实施例提出的无线感知方法中，可以通过能耗少、尺寸小的第一设备来反向散射无线感知信号发送端发送的至少部分信号，以提供新的感知路径甚至提供新的感知辅助信息，以提升ISAC系统的感知性能。
第二方面，在相关技术中，低功耗、低复杂度的反向散射通信(Backscatter Communications，BSC)技术是一种简单地依靠被动反射和调制入射射频(Radio Frequency，RF)波的技术，近年来在消费电子、5G通信技术和云计算支持的大数据分析技术的进步推动下，物联网的快速增长引起了业界和学术界的极大关注。物联网面临的主要开放挑战之一是，由于大量物联网设备由容量有限的电池供电，网络生命周期有限。而BSC技术在应对这一挑战方面已成为一种有前途的技术。
具体的，传统无线电体系结构存在耗电的射频链路，其包含振荡器、混频器和数字-模拟转换器，这导致了设备尺寸较大，同时大大限制了物联网设备的电池寿命。相比之下，对于一个反向散射节点来说，其没有有源射频组件，因此硬件以具有极低的功耗(例如10μW)，便于在各种灵活的场合进行大规模部署，甚至在体内植入。
在过去的20年里，点对点BSC技术已经被广泛应用于射频识别(Radio Frequency Identification，RFID)的应用中，无源RFID标签可以向近场(通常是几厘米～一米)询问的阅读器报告ID。在早期阶段，物联网主要由用于物流和库存管理的RFID设备组成。然而，未来6G物联网预计将连接数百亿设备，完成更复杂、更多功能的任务，并产生全球范围的影响。这要求物联网节点之间的通信能力和范围(数十米)远超出原始RFID，即仅支持在数米范围内突发和低速率传输(仅传输预先写入的若干字节的ID序列)。传统的RFID通信距离在m量级，而下一代BSC通信距离一般有望达到km量级；传统的RFID采用二进制调制，通信速率一般不大于640Kbps；下一代BSC可采用高阶调制，通信速率至少能达到10Mbps，甚至是2Gbps。基于现有的BSC理论，利用先进的通信技术如小蜂窝网络、全双工、多天线通信、大规模访问和无线功率传输，以及微型无线电(如按钮大小的无线 电)和低功耗电子设备制造，使得上述目标得以实现。总结来说，物联网的不断发展为BSC技术提供了许多极具前景的应用场景，使得BSC成为近年来比较火热的研究方向。
通感一体化能够催生出一系列6G新应用，除了表1所列的几种典型感知用例，基于低功耗通信设备的通感一体化也将成为6G的一个重要应用场景。本申请实施例中，基于射频识别(Radio Frequency Identification，RFID)以及反向散射通信(Backscatter Communications)技术的无线感知，相比于相关技术中的设备解耦(Device-free)的无线感知，在实现基本的感知功能同时，还能够获取额外的感知目标信息，从而有望进一步增强感知/通感一体化性能。由于RFID和backscatter具有低成本、低功耗、利于大规模部署的优势，基于RFID/backscatter的感知以及通感一体化有望在6G中获得广泛应用。例如，在车联网中具有感知功能的路边单元(Roadside Unit，RSU)可通过自发自收通感一体化信号，与道路行驶车辆通信，同时完成车辆定位、测速、轨迹追踪。当车辆上安装了RFID或者backscatter标签(tag)，tag能够额外提供车辆ID、车辆当前状态等辅助信息。RSU通过接收tag的反射信号，在实现高精度的车辆定位、测速、轨迹追踪同时，还能够精确识别、区分道路上的不同车辆，拓展了感知能力。但是，基于RFID的无线感知中的关键技术，如基于tag的通感一体化波形设计、帧结构设计、感知方案与算法设计都是需要研究和解决的问题。
本申请实施例提供一种基于第一设备反向散射功能的无线感知方案，以使第一设备能够应用于无线感知。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的无线感知方法、装置、网络侧设备和终端进行详细地说明。
请参阅图2，本申请实施例提供的第一种无线感知方法，其执行主体可以是第一设备，该第一设备具有反向散射功能，例如：第一设备可以包括射频识别(Radio Frequency Identification，RFID)tag和反向散射Backscatter tag等具有反向散射功能(或称之为后向散射功能)的设备，在此不作穷举，且为了便于说明，以下实施例中以第一设备为tag为例进行举例说明，且所述第一设备可以包括一个tag或者包括多个tag组成的tag阵列，当然，除了tag之外，第一设备还可以包括其它具有反向散射功能的设备，甚至还可以包括其它传感器件等，在此不作具体限定。
如图2所示，该第一种无线感知方法可以包括以下步骤：
步骤201、第一设备向无线感知信号接收端反向散射目标感知信号，其中，所述目标感知信号来自无线感知信号发送端，所述无线感知信号发送端包括第一终端或第一网络侧设备，所述无线感知信号接收端包括第二网络侧设备。
在实施中，第一设备可以具有天线，且该天线的信号采集范围大于等于第一设备与无线感知信号接收端之间的第一距离，且大于等于第一设备与无线感知信号发送端之间的第二距离，从而能够实现利用第一设备的天线来采集来自无线感知信号发送端的目标感知信号，且反向散射的目标感知信号能够被无线感知信号接收端接收，且无线感知信号接收端 接收该目标感知信号的信号质量或信号强度等满足感知需求对应的感知条件，即所述第一设备位于所述无线感知信号发送端和所述无线感知信号接收端的覆盖范围内，所述第一设备通过调节天线的匹配阻抗等过程，以实现反向散射天线采集到的无线感知信号。
在具体实施中，上述第一设备具有反向散射功能，即第一设备是一种低功耗且低复杂程度，且支持反向散射通信的设备，该支持反向散射通信的设备可以通过调制和反向散射(以下实施例中可以简称为“反射”)从环境中接收到的无线信号来发送信息，而不需要耗电的收发器、放大器等传统通信模块，可以实现极低功耗和低成本通信。可选地，支持反向散射通信的设备可选择采集周围无线信号的能量或其他能量用于其通信，从而实现甚至零功耗通信。
另外，上述无线感知信号发送端可以是第一网络侧设备(例如：基站或发送接收点(Transmit Receive Point，TRP))或者第一终端，上述无线感知信号接收端可以是第二网络侧设备(例如：基站或TRP)。
例如：如图3a所示，无线感知信号接收端可以是基站，且无线感知信号发送端可以是基站或终端，即基站A发感知信号，部分或全部信号经过tag反向散射，基站B接收感知信号；或者用户设备(User Equipment，UE)发送感知信号，部分或全部信号经过tag反向散射，基站接收感知信号。
当然，在实际应用中，无线感知信号接收端也可能是终端，或者与无线感知信号发送端是同一网络侧设备或同一终端，例如：如图3b和图3c所示，其中，图3b所示实施例中，无线感知信号接收端与无线感知信号发送端为同一设备(基站或终端)，即基站发送感知信号，部分或全部信号经过tag反向散射，所述基站接收感知信号；或者，UE发送感知信号，部分或全部信号经过tag反向散射，所述UE接收感知信号。图3c所示实施例中，无线感知信号接收端可以是UE，且无线感知信号发送端可以是基站或终端，即UE A发感知信号，部分或全部信号经过tag反向散射，UE B接收感知信号；或者，基站发送感知信号，部分或全部信号经过tag反向散射，UE接收感知信号。
本申请实施例主要针对如图3a所示应用场景进行说明，即基站接收终端或另一基站发送，且至少部分经第一设备反向散射的感知信号，以获取感知测量量。
可选地，在所述第一设备向无线感知信号接收端反向散射目标感知信号之前，所述方法还包括：
所述第一设备接收来自所述无线感知信号发送端的第一指示信息，其中，所述第一指示信息用于指示所述第一设备需要向所述无线感知信号接收端反馈的第一信息；
所述第一设备向无线感知信号接收端反向散射目标感知信号，包括：
所述第一设备将所述第一信息调制在所述目标感知信号上，以供无线感知信号接收端接收调制后的所述目标感知信号。
在具体实施中，上述第一指示信息用于指示第一设备在目标感知信号中调制指定的第一信息，所述目标感知信号可以理解为：用于感知测量的感知信号。
在一种可选的实施方式中，所述第一指示信息和所述目标感知信号可以是无线感知信号发送端在不同时间发送的信号，例如：第一设备先获取到第一指示信息后，并根据第一指示信息确定第一信息。经过一段时间(time gap)后，第一设备将先前确定的第一信息调制到感知信号上并反向散射该感知信号，无线感知信号接收端接收调制后的感知信号。其中，第一设备将第一信息调制到感知信号上，可以理解为：第一设备通过调节匹配阻抗等过程，对所述第一设备所处环境中的感知信号的幅度，或者相位，或者频率等产生影响，以实现调制该感知信号，并使该感知信号承载所述第一信息。
在另一种可选的实施方式中，所述第一指示信息和所述目标感知信号可以位于同一段信号的不同信息域，例如：某一信号的头部区域可以携带第一指示信息，该信号的其他区域可以看做是用于感知测量的感知信号。
在实施中，所述第一设备可以解调接收到的信号，以从中获取第一指示信息，并按照该第一指示信息的指示来准备需要调制到反向散射的感知信号中的第一信息，此时，第一设备可以提供额外的第一信息，例如：第一设备的位置信息、第一设备附属的目标感知对象的信息等，这样，可以利用第一信息为无线感知过程提供辅助，甚至可以直接将第一设备的第一信息作为感知结果，提升了无线感知过程的感知性能。
可选地，所述无线感知信号发送端发送的所述目标感知信号可以是未经调制的连续波(Continuous Wave，CW)信号，所述第一设备将所述第一信息调制在所述目标感知信号上，包括：
所述第一设备将所述第一信息调制到所述CW信号上。
其中，所述第一指示信息可以指示所述第一设备需要在反向散射的目标感知信号中调制哪些第一信息，例如：所述第一信息包括上述第一设备收集到的第二测量量，或者还可以把控其他预先存储在tag的相关信息，例如：tag将第一信息调制到所述CW信号中。
本实施方式中，第一设备可以在反向散射的目标感知信号中调制第一信息，以为感知过程提供除了感知测量量以外的其他信息，从而有利于提升感知系统的感知性能。
需要说明的是，在实际应用中，所述第一设备接收的目标感知信号还可以是其他信号类型，且所述第一设备反向散射所述目标感知信号的方式，以及在反向散射的所述目标感知信号内携带第一信息的方式可以适应性调整，在此不作具体限定。
当然，在其他实施例中，第一设备也可以不获取第一指示信息，而直接反向散射感知信号，此时，第一设备反向散射的感知信号中可以不携带第一设备添加的第一信息。
例如：无线感知信号发送端发送的感知信号是波形、比特序列以及频率范围等信号配置信息已知的或预先确定的预设感知信号序列。该预设感知信号序列被第一设备反向散射至无线感知信号接收端，无线感知信号接收端可以基于所述目标感知信号序列和预设感知信号序列进行目标信号处理，以得到目标测量量。目标信号处理包括但不局限于匹配滤波、互相关、滑动相关等操作，目标信号处理的结果是得到目标测量量。
需要说明的是，在实际应用中，无线感知信号发送端发送的感知信号还可以是至少两个间隔发送的感知信号，在此不作具体限定。
需要说明的是，在感知信号接收端接收至少部分经第一设备反向散射的目标感知信号时，可以对目标感知信号进行测量、解调等处理中的至少一项，以获取目标测量量。所述目标感知需求信息所需求的目标感知结果基于所述目标测量量确定，当然，基于所述目标测量量确定目标感知结果的节点可以是基站、UE、核心网或应用服务器，在此不作具体限定。例如：无线感知信号接收端可以根据获取的目标测量量计算出目标感知结果，再直接或间接地将目标感知结果发送给感知业务的发起方，或者，感知信号接收端可以将目标测量量发送给其他基站、UE、核心网或应用服务器中的至少一项，以通过其他基站、UE、核心网或应用服务器中的至少一项计算出目标感知结果后，发送给感知业务的发起方。
值得注意的是，相比于只有基站和用户移动终端参与的感知方式(即基站自发自收感知信号、基站A发基站B收感知信号、基站和终端之间发送和接收感知信号、终端自发自收感知信号、终端A发终端B收感知信号)，tag的加入有以下几个方面好处：
(1)tag具有低功耗、低成本、小体积的特点，十分适合大规模部署在环境中，因此相对于上述几种感知方式，能够大幅度增大感知范围(增大感知物理距离、物理角度范围、增大感知网络密度)、提高感知性能(提高感知分辨率，降低感知误差，提高感知信噪比等)；
(2)tag既可以部署在环境中，也可以部署在感知目标上。无论部署在哪里，都能够为感知方提供额外的感知信息(环境信息、感知目标物体信息)，辅助device-free(设备解耦)类感知提升感知性能，同时又相对于device-based(基于设备)感知具有更低的功耗以及更少的信令开销；
(3)tag经过人为设计，其本身的反向散射特性相对于device-free类感知物体的反射特性要更稳定，相对更不容易受到感知距离、感知(观测)方向的干扰，更容易被感知方探测到，提高了感知鲁棒性；
(4)tag部署方式灵活，通过在一些感知信号难以传播的路径上巧妙部署若干个tag或者tag阵列，还有望能起到一定的感知补盲作用；
(5)tag上的存储信息(例如tag ID、tag位置坐标、tag数量、tag通信能力、tag所属目标的物理信息等)可作为一种先验信息在部署之初就存储在核心网的感知网络功能单元(Sensing Network Function，SNF)或者类似网络功能单元中，或者tag存储的先验信息可供tag接入的基站或终端读取，因此，能够为网络提供更丰富、更灵活的感知方案，实现更多感知功能；
(6)tag本身的成本相对于基站和终端要低很多，未来新一代的反向散射tag其本身就具备较强的通信功能，因此基于tag的感知天然成为通感一体化的一种经济、高效、低复杂度的实现方式。
需要说明的是，在应用中，上述目标感知信号可以是某一具体的感知业务中的感知信 号，例如：天气监测，重构三维地图，交通/人群感知，空气质量检测例如PM2.5监测、工厂污染物检测，农场家畜监测，或人的动作/姿势识别等感知业务。
该感知业务的发起方可以是第三方应用、核心网(或者网管系统，或者基站)或者UE。

在无线感知信号接收端获取到目标测量量后，完成目标测量量到目标感知结果的节点，可以将目标感知结果直接或间接的发送给感知业务的发起方。
例如：若目标测量量到目标感知结果的转换在核心网完成，则感知业务的发起方可以通过以下方式获取目标感知结果：
基站B把目标测量量发送给核心网(AMF或感知网元)，或者，基站B把目标测量量发送给感知信号发送端(基站A或UE)，基站A或UE把目标测量量发送给核心网(AMF或感知网元)；
核心网(AMF或感知网元)把目标测量量转换为目标感知结果；
核心网(AMF或感知网元)(通过NAS信令)把目标感知结果发送给感知业务发起UE；或者，核心网(AMF或感知网元)将目标感知结果发送给感知业务发起UE关联的基站，关联基站再把目标感知结果发送给感知业务发起UE。
再例如：若目标测量量到目标感知结果的转换在基站完成，则感知业务的发起方可以通过以下方式获取目标感知结果：
基站B把目标测量量转换为目标感知结果，并把目标感知结果发送给核心网(AMF或感知网元)；
核心网(AMF或感知网元)(通过NAS信令)把感知结果发送给感知业务发起UE；或者，核心网(AMF或感知网元)将感知结果发送给感知业务发起UE关联的基站，关联基站再把感知结果发送给感知业务发起UE。
再例如：若目标测量量到目标感知结果的转换在UE(可以是上述感知业务发起UE)完成，则感知业务的发起方可以通过以下方式获取目标感知结果：

UE根据目标测量量确定目标感知结果。

作为一种可选的实施方式，所述方法还包括：
所述第一设备配合所述无线感知信号发送端以及所述无线感知信号接收端进行参考测量，其中，所述参考测量用于获取参考测量量或参考测量结果，所述目标感知结果基于所述目标测量量，以及所述参考测量量或参考测量结果确定。
对于某些基于tag的感知业务，需要进行参考测量。最终感知结果的确定，需要基于感知业务执行完后得到的直接感知结果以及参考测量的感知结果共同确定。例如，对于某个分布有tag的区域内的物体进行检测、定位、成像等，需要在物体不在区域时进行参考测量，相应测量量为tag的反射信号RSSI、相位；物体进入tag区域后，再进行一次测量，完成感知流程；再比如，对于分布有tag区域的天气(如湿度、降雨)进行感知，需要在某个湿度或无降雨时段内的进行参考测量。
需要说明的是，上述进行参考测量，以获取参考测量量或参考测量结果的过程，与上述获取目标测量量或目标测量结果的过程相似，不同之处在于参考测量的感知发起方不一定是第三方应用，也可以是核心网(或感知网元)，或者基站，或者UE，且测量环境可能不同。
在实施中，上述参考测量量或参考测量结果可存储在核心网(或感知网元)或者参与感知的tag上，也可存储在基站上，以使完成目标测量量到目标测量结果的节点，能够获取该参考测量量或参考测量结果，另外，参考测量和感知业务执行的时间先后没有严格要求，例如：可以先执行参考测量，然后执行感知业务，以根据参考测量量或参考测量结果来修正目标测量量或目标测量结果的误差，或者，也可以先执行感知业务，然后执行参考测量，最终，综合目标测量量，以及参考测量量或参考测量结果，来确定目标感知结果。
本实施方式中，可以通过参考测量来提升感知结果的精确度，以减少感知误差。
在一些实施例中，以上流程中的感知信号可以由多个基站或UE发送，和/或，感知信号接收端也可以是多个基站，和/或，参与感知的tag数目也可以是一个或者多个；此时，核心网需要决定发送感知信号的基站、UE集合，参与感知tag集合，以及接收感知信号的UE集合，并把多个基站、UE的感知信号相关配置信息、参与感知的tag相关信息分别发给对应的多个基站、UE，并把需要接收基站测量的感知信号相关的测量量、参与感知的tag相关信息分别发给对应的多个接收基站。
可选的，多个发送基站、UE之间需要交互感知信号相关配置信息(例如充当协调者的基站或者UE把感知信号相关配置信息、参与感知的tag相关信息发给其他发送基站、UE，把感知信号相关的测量量、参与感知的tag相关信息发给其他接收基站)。其中，上述流程中核心网网络功能或网元(如感知网络功能/感知网元)与UE之间的消息交互可以是通过基站，或者，该消息对基站是透明的，例如NAS信令。
需要说明的是，上述流程中的基站可以是TRP，例如：基站A为TRP A，基站B为TRP B，此时，TRP A和B可以属于相同的或者不同的基站。

在一些实施例中，所述第一设备获取第二感知请求消息，可以是所述第一设备接收来自基站/核心网的第二感知请求消息，上述第一设备输出第二感知响应消息，可以理解为：所述第一设备生成第二感知响应消息，以供基站或其他接入设备读取；或者，是将所述第二感知响应消息调制在接收的无线信号上，以供基站或其他接入设备接收。例如：基站/核心网根据感知需求信息，初步的选择参与感知的tag，并向选中的tag发送第二感知请求消息，以从该tag中读取参与感知的状态指示信息，若指示tag同意参与感知过程，则可以将其确定为参与感知过程的第一设备，若指示tag不同意参与感知过程，则可以重新选取其他tag。
所述第一设备可以接收来自基站/核心网的所述第二感知请求消息，并向该基站/核心网反馈第二感知响应消息，以告知基站/核心网该第一设备是否同意参与感知过程，或者是否同意提供第一信息。
本实施方式中，tag在反射感知信号过程中，可以选择同意或拒绝参与感知过程和/或提供存储在tag上的有关先验信息。
当然，在实施中，第一设备还可以通过其他方式实现选择同意或拒绝参与感知过程和/或提供存储在tag上的有关先验信息。
例如：基站/核心网确定参与感知服务的tag时(对应上述步骤3))，tag通过参与感知的状态指示信息，指示同意/拒绝参与感知和/或提供存储在tag上的有关先验信息；或者，
基站/核心网确定参与感知服务的tag后(对应上述步骤3))，基站对tag进行选择、盘存、访问(读写信息)等操作，tag通过参与感知的状态指示信息，指示同意/拒绝提供存储在tag上的有关先验信息；或者，
tag是否可以参与相关感知服务是事先约定好的，存储在核心网相关存储节点(例如：统一数据存储库(Unified Data Repository，UDR))，核心网网络功能或网元(如感知网络功能/感知网元)收到感知需求并筛选参与感知服务的tag后(对应上述步骤3))，访问存储关联tag是否可以参与相关感知服务的存储节点，获取tag是否可以参与相关感知服务和/或提供存储在tag上的有关先验信息的信息。
与上述tag选择同意或拒绝参与感知过程相似的，UE也可以选择同意或拒绝参与感知过程，方法可以是：
核心网网络功能或网元(如感知网络功能/感知网元)向UE发送感知需求后，UE同意或拒绝，在同意提供感知需求的UE中筛选参与感知服务的UE(对应上述步骤3))；或者，
基站/核心网筛选参与感知服务的UE后(对应上述步骤3))，向关联UE发送参与感 知请求消息，UE同意或拒绝；或者，
UE是否可以参与相关感知服务是事先约定好的，存储在核心网相关存储节点例如UDR，核心网网络功能或网元(如感知网络功能/感知网元)收到感知需求并筛选参与感知服务的UE后(对应上述步骤3))，访问存储关联UE是否可以参与相关感知服务的存储节点，获取UE是否可以参与相关感知服务的信息。
