为使本领域技术人员能够更好地理解本申请实施例，先进行如下说明。
未来移动通信系统例如超五代(Beyond 5th Generation，B5G)系统或6G系统除了具备通信能力外，还将具备感知能力。感知能力，即具备感知能力的一个或多个设备，能够通过无线信号的发送和接收，来感知目标物体的方位、距离、速度等信息，或者对目标物体、事件或环境等进行检测、跟踪、识别、成像等。未来随着毫米波、太赫兹等具备高频段大带宽能力的小基站在6G网络的部署，感知的分辨率相比厘米波将明显提升，从而使得6G网络能够提供更精细的感知服务。典型的感知功能与应用场景如表1所示。
表1
通信感知一体化即在同一系统中通过频谱共享与硬件共享，实现通信、感知功能一体化设计，系统在进行信息传递的同时，能够感知方位、距离、速度等信息，对目标物体或事件进行检测、跟踪、识别，通信系统与感知系统相辅相成，实现整体性能上的提升并带来更好的服务体验。
通信与雷达的一体化属于典型的通信感知融合应用，在过去，雷达系统与通信系统由 于研究对象与关注重点不同而被严格地区分，大部分场景下两系统被分发研究。事实上，雷达与通信系统同样作为信息发送、获取、处理和交换的典型方式，不论工作原理还是系统架构以及频段上存在着不少相似之处。通信与雷达一体化的设计具有较大的可行性，主要体现在以下几个方面：首先，通信系统与感知系统均基于电磁波理论，利用电磁波的发射和接收来完成信息的获取和传递；其次，通信系统与感知系统均具备天线、发送端、接收端、信号处理器等结构，在硬件资源上有很大重叠；随着技术的发展，两者在工作频段上也有越来越多的重合；另外，在信号调制与接收检测、波形设计等关键技术上存在相似性。通信与雷达系统融合能够带来许多优势，例如节约成本、减小尺寸、降低功耗、提升频谱效率、减小互干扰等，从而提升系统整体性能。
根据感知信号发送节点和接收节点的不同，分为以下6种感知链路，需要注意的是，下面描述每种感知链路都以一个发送节点和一个接收节点作为例子，实际系统中，根据不同的感知需求可以选择不同的感知链路，每种感知链路的发送节点和接收节点可以有一个或多个，且实际感知系统可以包括多种不同的感知链路。
1)基站回波感知。这种方式下基站发送感知信号，并通过接收该感知信号的回波来获得感知结果。
2)基站间空口感知。此时，基站2接收基站1发送的感知信号，获得感知结果。
3)上行空口感知。此时，基站接收终端设备(UE)发送的感知信号，获得感知结果。
4)下行空口感知。此时，UE接收基站发送的感知信号，获得感知结果。
5)终端回波感知。此时，UE发送感知信号，并通过接收该感知信号的回波来获得感知结果。
6)终端间旁链(Sidelink)感知。例如，UE 2接收UE 1发送的感知信号，获得感知结果。
在实际执行感知业务的过程中，通常存在硬件非理想因素，会对感知测量准确性造成影响，尤其是上述6种方式中收发设备不同的情况，在发送端和接收端都需要产生相应的载波以完成相应的上变频和下变频操作。发端需要通过上变频将发射信号搬移到特定频点进行发送，而接收端则需要将接收信号下变频到基带以方便后续处理。收发时钟通常无法保证完全一致，收发晶体振荡器都有各自的准确度，造成了系统所产生的载波信号频率与理想频率存在偏差，该偏差是接收信号载波频率偏移的主要来源之一。此外，信道移动性也会导致载波频率偏移。
根据上述描述可知，基于接收信号计算得到的频率偏移信息不仅包含信道移动性带来的多普勒频率偏移，还包括收发时钟偏差，对于通信业务而言，通常不需要对两者进行区分，仅需对接收信号整体进行频偏补偿，满足解调性能即可，而感知业务通常需要得到信道多普勒信息，从而进行对环境中动态目标的检测。收发时钟偏差对多普勒测量的影响具体解释如下：
假设不存在收发频偏，发送信号为s(t)，信道中存在H个反射体，接收端经过下变频 后得到基带接收信号为：
其中，表示随机相位旋转，为白高斯噪声，bh为幅度衰减因子，fD,h为信道第h个反射体对应的多普勒频移信息，τh为第h个反射体对应的时延。
此时，接收端通过检测时域维度的相位变化(时域快速傅里叶变换(fast Fourier transform，FFT))即可得到信道多普勒频移信息。但实际系统中，收发设备时钟无法保证完全一致，即存在收发频偏，假设发端载波频率为ft，接收端载波频率为fr，且ft≠fr。
则接收端经过下变频后存在残余频差ft-fr，即基带接收信号为：
此时，接收端通过检测时域维度的相位变化，例如进行时域FFT运算，无法得到原始信道多普勒频移信息。
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多普勒测量方法进行详细地说明。
如图2所示，本申请实施例提供了一种多普勒测量方法，包括：
步骤201：第一设备获取第一信息和第二信息。
其中，所述第一信息是第三设备通过测量第二设备发送的第一信号得到的多普勒频移信息，所述第二信息是第二设备通过测量第三设备发送的第二信号得到的多普勒频移信息。
本步骤中，第一设备获取第三设备发送的第一信息，并获取第二设备发送的第二信息。
本申请中的第一设备可以是核心网感知网络功能设备，第二设备可以是网络侧设备，如基站，第三设备可具体为终端。
可选地，本申请实施例中，网络侧设备通过下行时隙发送第一信号，终端通过上行时隙发送第二信号。
步骤202：所述第一设备根据所述第一信息和第二信息，得到目标信息，所述目标信息用于指示所述第二设备和所述第三设备之间的多普勒频移信息，所述多普勒频移信息是与信道中感知目标的运动关联的多普勒频移信息。所述多普勒频移信息是与信道中感知目标的运动关联的多普勒频移信息。即多普勒频移信息是由信道中感知目标的运动引起的多普勒频移信息。
可选地，基于上述第一信息和第二信息采用预设算法(如将两个多普勒测量结果相加后除以2)来抵消掉收发时钟偏差，得到目标信息，即所述第二设备和所述第三设备之间的多普勒频移信息。
本申请实施例中，第二设备发送第一信号给第三设备，第三设备进行测量得到第一信息并发送给第一设备；第三设备发送第二信号给第二设备，第二设备对第二信号进行测量得到第二信息并发送给第一设备；第一设备根据第一信息和第二信息得到目标信息，具体 的：
在一实现方式中，第二设备的发送信号s(t)(即第一信号)经过上变频后表示为：
第三设备对接收到的第一信号经过下变频后的接收信号表示为：
第三设备基于r(t)计算得到第一信息：
fD1,h＝fD,h+(ft-fr)h＝0,1,...,H-1；
第三设备向第一设备发送第一信息，并向第二设备发送第二信号s2(t)：
第二设备接收s2(t)并下变频得到：
第二设备基于r2(t)得到第二信息并发送给第一设备：
fD2,h＝fD,h+(fr-ft)h＝0,1,...,H-1；
基于第一信息和第二信息得到目标信息：
即经过第二设备和第三设备双向发送测量信号进行多普勒测量后，两次多普勒测量结果(第一信息和第二信息)合并时收发时钟频率偏差的影响被抵消掉(即fr-ft被抵消掉)，得到的目标信息不受到收发时钟频率偏差的影响。
需要说明的是，本申请实施例中的多普勒频移信息包括由信道中的至少一个感知目标的运动引起的多普勒频移信息。作为一种实现方式，上述感知目标为上述反射体中的至少一个。
本申请实施例中，第一设备获取第一信息和第二信息；所述第一设备根据所述第一信息和第二信息，得到目标信息；其中，所述第一信息是第三设备通过测量第二设备发送的第一信号得到的多普勒频移信息，所述第二信息是第二设备通过测量第三设备发送的第二信号得到的多普勒频移信息，所述目标信息用于指示所述第二设备和所述第三设备之间的多普勒频移信息。由于上述第一信息中包含有收发设备的时钟频率偏差，第二信息中也包含有收发设备的时钟频率偏差，而且第一信息和第二信息所对应的收发设备是相对的，因此，基于上述第一信息和第二信息采用一定的算法能够抵消掉收发时钟频率偏差，准确地得到第二设备和所述第三设备之间的多普勒频移信息，提升了多普勒测量的准确性。
可选地，所述第一信号和所述第二信号具有相同的时域资源格式；

需要说明的是，接收端多普勒的计算需要基于信号时域相位变化，即2πfdΔT＝θ，其中θ为ΔT时间感知信号时域相位变化，在不考虑速度方向时，为了保证不发生多普勒模糊，需要满足θ＝2πfdΔT≤2π，即最大无模糊多普勒频移与信号时域间隔关系为ΔT≤1/(fd max)，最大不模糊速度与最大无模糊多普勒频移关系为vmax＝fd maxc/2fc，因此最大不模糊速度与信号时域间隔关系为ΔT≤c/(2fcvmax)；考虑速度方向时，为保证不发生多普勒模糊，需要满足θ＝|2πfdΔT|≤π，即最大无模糊多普勒频移与感知信号时域间隔关系为ΔT1≤1/(2|fd max|)，最大不模糊速度与感知信号时域间隔关系为ΔT1≤c/(4fc|vmax|)。
