基于此，为便于对本申请提供的技术方案进行理解，下面对本申请中涉及的相关技术进行介绍，内容如下。
如图1b所示，参数t表示时变信道，时域信道脉冲响应c(τ,t)在时刻t包含N(t)条传播路径(或路径)，每条传播路径由三个参数确定：幅度信息αn(t)，相位信息时延信息τn(t)，其分别描述的是：信号从发射端到接收端的传播，在每条路径(如图1b中所示的路径0、路径1、路径2)上经历的幅度衰减、相位变化和传播延迟不同。对此，在无线通信系统中，可通过对路径进行准确地建模和估计，以便进行信号恢复/校正、设备定位等。
其中，以基于正交频分复用(Orthogonal frequency division multiplex，OFDM)的无线通信系统为例，如图1c所示，为了估计时域信道脉冲响应，接收端可对发射端发射的导频信号在时域进行采样，然后通过快速傅里叶变换(Fast Fourier Transform，FFT)将时域信号变换到频域得到频域的导频信号，由于导频序列接收端已知，因此可以估计得到信道频率响应。其中，信 道频率响应描述的是无线信号在不同子载波上所经历的幅度和相位的变化。最后，将信道频率响应通过逆快速傅里叶变换(Inverse Fast Fourier Transform，IFFT)变换得到时域信道脉冲响应。
实际上，通过上述过程估计得到的时域信道脉冲响应是存在误差的，一种典型情况是估计的时域信道脉冲响应，在真实传播路径对应的抽头附近，也会检测到“假的”传播路径，也就是说实际情况下，这些抽头上信道脉冲响应的幅度应该是0，由于硬件实现上的一些非理想因素导致这些抽头上检测到传播路径。非理想因素包括信道频率响应的估计误差、信道频率采样点数与IFFT的变换区间长度不一致等。对于第二点，下面是一个例子，比如100MHz的带宽，子载波间隔是30kHz，假设导频布满整个带宽共3276个子载波，通过上述流程估计信道频率响应的维度为3276*1，也就是信道频率采样点数为3276；为了方便硬件实现，FFT和IFFT的点数一般设置为2的整数次幂，且大于信道频率采样点数，比如IFFT点数为4096。
基于此，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技术方案进行详细地说明。
如图2所示，为本申请一示例性实施例提供的定位方法200的流程示意图，该方法200可以但不限于由第一设备执行，具体可由安装于第一设备中的硬件和/或软件执行。本实施例中，所述方法200至少可以包括如下步骤。
S210，第一设备按照目标规则获取第一信息。
其中，在本实施例中，所述第一设备可以通过对目标参考信号(如下行测量时的定位参考信号(Positioning Reference Signal，PRS)、上行测量时的探测参考信号(Sounding Reference Signal，SRS)等)进行测量，进而根据测量结果和所述目标规则获取所述第一信息(如用于所述目标参考信号测量的信道的路径信息或信道的抽头符号信息)，以用于设备定位。其中，对于前述的目标参考信号，在进行下行定位、且所述第一设备为终端时，所述目标参考信号可以为网络侧设备发送的PRS；在进行上行定位、且所述第一设 备为网络侧设备时，所述目标参考信号可以为终端发送的SRS，在此不做限制。
值得注意的是，本申请基于所述目标规则获取所述第一信息的目的是：为了在基于所述第一信息和定位模型进行设备定位时，能够对齐用于设备定位的所述第一信息与用于训练所述定位模型的第二信息，如使得用于设备定位的所述第一信息与用于训练所述定位模型的第二信息(也可称作模型训练集)相关，如第一信息与第二信息具有相同的获取方式、获取规则或处理方式等，以使得在设备定位时，定位模型所采用的第一信息的类型与第二信息的类型等一致/匹配，进而大幅改善基于所述第一信息和所述定位模型进行设备定位的定位结果的准确性，避免相关技术中在进行设备定位时，由于采用常规(Legacy)方式获取第一信息(如信道的路径信息或信道的抽头符号信息)，而存在的所述第一信息与模型训练集的路径信息选择方式不一致的问题。
在此情况下可以理解的是，所述第一设备在按照所述目标规则获取所述第一信息时，所述目标规则中可配置有所述第一信息的获取方式，且所述第一信息的获取方式与第二信息的获取方式相关，所述第二信息用于训练与所述设备定位相关的定位模型，以确保用于设备定位的所述第一信息与用于训练所述定位模型的第二信息(也可称作模型训练集)相关。可选的，在本实施例中，根据定位场景的不同，所述目标规则可以协议约定、高层配置或网络侧配置等方式实现，在此不做限制。
另外，前述的所述信道的路径信息(或传播路径信息)是指通过相关算法根据信道频率响应或时域信道脉冲响应估计得到的多径信息，本实施例中，所述信道的路径信息包括路径时延信息、路径功率信息、路径相位信息中的至少一项。
以及，所述信道的抽头符号信息(或称作符号信息)是指接收机按既定方式或规则对信道频率响应进行处理得到时域信道脉冲响应，进而根据时域 信道脉冲响应各个抽头上的符号信息。本实施例中，所述信道的抽头符号信息包括抽头符号时延信息、抽头符号功率信息、抽头符号相位信息中的至少一项。
而对于前述的定位模型，该定位模型可以为人工智能(AI)模型。值得注意的是，本申请后续提及的中所述的为AI模型也可称为AI单元、AI模块、机器学习(machine learning，ML)模型、ML单元、AI结构、AI功能、AI特性、机器学习模型、神经网络、神经网络函数、神经网络功能、决策树、支持向量机、贝叶斯分类器等，或者所述AI模型也可以是指能够实现与AI相关的特定的算法、公式、处理流程、能力等的处理单元，或者所述AI模型可以是针对特定数据集的处理方法、算法、功能、模块或单元，或者所述AI模型可以是运行在GPU、神经网络处理器(Neural network Processing Unit，NPU)、张量处理单元(Tensor Processing Unit，TPU)、专用集成电路(Application Specific Integrated Circuit，ASIC)等AI/ML相关硬件上的处理方法、算法、功能、模块或单元，本申请对此不做具体限定。可选地，所述特定数据集包括AI模型的输入或输出。
以及，所述AI模型的标识，可以是AI结构标识、AI算法标识，或者所述AI模型关联的特定数据集的标识，或者所述AI/ML相关的特定场景、环境、信道特征、设备的标识，或者所述AI/ML相关的功能、特性、能力或模块的标识，在此不做具体限定。
本实施例中，第一设备通过获取用于设备定位的第一信息，而所述第一信息的获取方式与第二信息的获取方式相关，且所述第二信息用于训练与所述设备定位相关的定位模型，由此，能够在进行设备定位时，使得与设备定位相关的定位模型所采用的第一信息与用于训练所述定位模型的第二信息相关，以大幅提升基于所述定位模型和所述第一信息进行设备定位的定位结果的精度。
如图3a所示，为本申请一示例性实施例提供的定位方法300的流程示意 图，该方法300可以但不限于由第一设备执行，具体可由安装于第一设备中的硬件和/或软件执行。本实施例中，所述方法300至少可以包括如下步骤。
S310，第一设备按照目标规则获取第一信息。
其中，所述第一信息用于设备定位，所述目标规则中配置了所述第一信息的获取方式，所述第一信息的获取方式与第二信息的获取方式相关，所述第二信息用于训练与所述设备定位相关的定位模型。
可以理解，S310的实现过程除了可参照方法实施例200中的相关描述之外，一种实现方式中，所述第一信息可以是基于T个TRP或小区对应的信道测量信息(如信道的路径信息或抽头符号信息等)确定，而所述信道测量信息可以基于目标参考信号进行测量得到，T为大于或等于1的整数。
另一种可能的实现方式，所述第一设备按照目标规则获取第一信息的获取方式可以包括以下(11)-(14)中的至少一项。
(11)根据时延信息从测量到的多条径(即路径或传播路径)中选取N(N为大于或等于1的整数)条径，并将所述N条径的相关信息作为所述信道的路径信息。例如，所述第一设备可以按照时延信息从测量到的多条径中选取N条径，如按照时延大小对所述多条径进行排序，排序靠前的N条径，或者，所述第一设备可以先将时延上的首径作为所述N条径中的第一条径，再根据功率信息从所述多条径中选取N-1条径，如功率最大的N-1条径等，所述N-1条径中不包括所述第一条径。
可以理解，本申请中提及的“时延上的首径”可以理解为多条径中时延最小的径。其中，其中，所述第一设备在获取N条径的信息后，若需要向其他设备发送该N条径的信息，则可以同时发送该N条径的信息，也可以分别发送首径信息以及N-1条径的信息，对应的，若需要向其他设备指示N条径的信息的获取方式，可以同时指示该N条径的信息的获取方式，也可以分别指示首径信息的获取方式以及N-1条径的信息的获取方式，在此不做限制。
(12)根据功率信息(如参考信号接收路径功率(Reference Signal  Received Path Power，RSRPP)等)从测量到的多条径中选取N(N为大于或等于1的整数)条径，并将所述N条径的相关信息作为所述信道的路径信息。例如图3b所示，假设可将时域信道脉冲响应的峰值对应的抽头上的符号作为路径信息，如路径1、路径2、路径3、路径4，且N为2，那么，可将选择前2个功率最强的传播路径，如路径1和路径2；又例如，也可以根据信道频域响应和多信号分类(Multiple Signal Classification，MUSIC)算法估计多径信息，再根据估计结果选择前N个功率最强的传播路径，本实施例对此不做限制。
(13)根据时延信息从测量到的多个抽头符号中选取M(M为大于或等于1的整数)个抽头符号，并将所述M个抽头符号的相关信息作为所述信道的抽头符号信息。例如，所述第一设备可按照时延信息从测量到的多个抽头符号中选取M个抽头符号；或，所述第一设备将时延上的首径对应的抽头符号作为M个抽头符号中的第一个抽头符号，以及按照功率信息从多个抽头符号中选取M-1个抽头符号，所述M-1个抽头符号中不包括所述第一个抽头符号。
(14)根据功率信息从测量到的多个抽头符号中选取M(M为大于或等于1的整数)个抽头符号，并将所述M个抽头符号的相关信息作为所述信道的抽头符号信息，例如图3c所示，假设测量到4个抽头符号、M为2，那么可直接根据时域信道脉冲响应，选取4个抽头符号中前2个功率最大的抽头符号，即抽头符号3和抽头符号4。
在此情况下，作为一种可能的实现方式，除了可以根据协议约定的方式获取所述目标规则之外，根据定位场景的不同，所述目标规则的获取方式还可以包括以下方式1-方式2中至少一项。
方式1：在所述第一信息用于第二设备进行设备定位的情况下，所述第一设备接收所述第二设备发送的第一指示信息，所述第一指示信息用于指示或包括所述目标规则。
也就是说，所述第二设备中部署有用于设备定位的定位模型，而所述第一设备用于获取第一信息并发送所述第一信息给第二设备，以使得所述第二设备可将所述第一信息作为所述定位模型的输入，以进行设备定位。其中，由于所述第一信息的获取方式与用于定位模型训练的第二信息(也可称作用于定位模型训练的训练数据集)相关(如二者一致)，因此，能够大幅提高所述第二设备基于所述第一信息和所述定位模型进得到的设备定位结果的精度。
可选的，所述第一设备在向所述第二设备发送所述第一信息的情况下，还可以向所述第二设备发送第三信息，以用于指示所述第一设备发送的所述第一信息的获取方式，由此，一方面，可使得所述第二设备可以在基于所述第一信息和所述定位模型进行设备定位时，能够进一步根据所述第三信息核对所述第一信息的获取方式是否与第二信息的获取方式相关，以确保定位结果的精确性；另一方面，对于配置有多个定位模型(适用于不同的配置)的第二设备(如网络侧)，还有助于第二设备选择合适的模型为第一设备(如终端)进行定位。
一种可能的实现方式中，所述第一设备还可以向所述第二设备发送第一能力信息，使得所述第二设备向所述第一设备指示的第一信息的获取方式与所述第一设备的能力匹配，进而确保所述第一信息的获取的可靠性。
可选的，所述第一能力信息可以包括或指示以下(21)-(22)至少一项。
(21)所述第一设备所支持的所述第一信息的获取方式。
其中，所述第一设备所支持的所述第一信息的获取方式可以包括但不限于前述(11)-(14)中所述，在此不再赘述。
(21)所述第一设备所支持的IFFT窗口的大小，所述IFFT窗口的大小与所述第一信息的获取相关，如所述IFFT变换窗口用于所述第一设备进行频域信道脉冲响应到时域信道脉冲响应的变换，所述时域信道脉冲响应用于所述第一信息的确定。
在此情况下，所述第二设备在接收到所述第一能力信息后，除了可以向所述第一设备发送第一指示信息以指示所述目标规则之外，所述第二设备还可以向所述第一设备发送第二指示信息，以用于指示或包括IFFT变换窗口的大小，所述IFFT变换窗口用于所述第一设备进行频域信道脉冲响应到时域信道脉冲响应的变换，所述时域信道脉冲响应用于所述第一信息的确定。那么，所述第一设备在接收到所述第二指示信息后，可根据其所指示的IFFT变换窗口的大小以及所述第一指示信息进行所述第一信息的获取，以确保获取到的所述第一信息的高可靠性。
可选的，在本实施例中，所述IFFT变换窗口的大小为以下(31)-(32)中一项。
(31)所述IFFT窗口的大小等于信道频率响应的子载波数量。
(32)所述IFFT窗口的大小大于信道频率响应的子载波数量、且为2的整数次幂。
其中，前述(31)-(32)中所述的信道频率响应可根据测量到的目标参考信号估计得到，所述目标参考信号可以是但不限于下行的PRS或上行的SRS等。
另外，除了前述的通过所述第二指示信息进行所述IFFT变换窗口的大小的指示外，一种实现方式中，还可以采用隐式指示的方式进行所述IFFT变换窗口的大小的指示，如第二设备(如网络侧设备)可在指示其他参数(如定位模型的相关参数、目标规则等)时，同时隐式指示所述IFFT变换窗口的大小，以节省网络开销，本实施例在此不做具体限制。
值得注意的是，在本方式1中，在所述第一设备为终端设备时，用于设备定位的所述第二设备可以是终端设备或接入网设备，而部署在所述第二设备中的定位模型可以由协议约定或核心网设备(如LMF等)或第三方服务器提供等方式实现。可以理解，如果所述第二设备为接入网设备，那么所述第二设备基于定位模型对所述第一设备进行终端定位。
在所述第一设备为接入网设备时，用于设备定位的第二设备可以为核心网设备(如LMF等)或第三方服务器等，且部署在所述第二设备中的定位模型可以协议约定等方式实现，在此不做限制。
方式2：在所述第一信息用于所述第一设备进行设备定位、且所述定位模型由第三设备提供的情况下，接收所述第三设备发送的第二指示信息，所述第二指示信息用于指示或包括所述目标规则。
也就是说，相对于方式1，该方式2中是由第一设备进行第一信息的获取，并基于所述第一信息和定位模型进行设备定位，而部署在所述第一设备中的定位模型则可以由协议约定或第三设备提供，因此，所述第三设备可以向所述第一设备指示所述目标规则，使得所述第一设备进行第一信息获取之前，可根据第三设备发送的目标规则确定第一信息的获取方式，进而确保第一信息的获取方式与用于所述定位模型训练的第二信息的获取方式相关(如一致)，进而确保基于获取的第一信息和定位模型进行设备定位的定位结果的精确性。
基于此，在一种实现方式中，所述第一设备还可以向所述第三设备发送第二能力信息，所述第二能力信息用于指示所述第一设备支持与所述目标规则关联的定位功能，由此，能够使得第三设备尽可能向所述第一设备提供其所支持的定位模型或第一信息的获取方式(即目标规则)，以进一步确保定位结果的精确性。
可选的，所述第二能力信息包括或指示以下(41)-(42)中的至少一项。
(41)所述第一设备所支持的至少一个定位功能的标识。
(42)所述第一设备支持基于定位模型的直接定位。其中，“基于定位模型的直接定位”可以理解为所述第一设备在将所述第一信息输入所述定位模型后，由所述定位模型的输出可以直接得到定位结果，如位置坐标、视线传输(Line of Sight，LOS)径到达时间(time of arrival，TOA)、LOS指示、非视线传输(Non Line of Sight，NLOS)指示等。所述定位模型可以为但不 限于AI模型。
(43)所述第一设备支持基于定位模型的辅助定位。其中，所述基于定位模型的辅助定位可以理解为在将所述第一信息输入所述定位模型后，由所述定位模型的输出的是中间特征量，所述第一设备还需要根据所述中间特征量进一步进行设备位置的估计，以实现设备定位，所述定位模型可以为但不限于AI模型。
(44)所述定位模型的输入或输出信息的类型。
值得注意的是，在本方式2中，在所述第一设备为终端设备时，向所述第一设备提供定位模型的第三设备可以是终端设备或接入网设备。
在所述第一设备为接入网设备时，向所述第一设备提供定位模型的第三设备可以是核心网设备(如LMF等)或第三方服务器。
值得注意的是，除了直接在所述第一指示信息、第二指示信息中携带所述目标规则之外，一种实现方式中，在所述第一设备中预先通过协议约定等方式配置有对应不同定位模型的多个目标规则，可通过所述第一指示信息或第二指示信息指示所述第一设备基于多个目标规则中的某一个目标规则进行第一信息的获取，也就是，所述第一指示信息中可以携带目标规则的标识信息等，由此，可以节省带宽资源，提高通信效率。
如图4所示，为本申请一示例性实施例提供的定位方法400的流程示意图，该方法400可以但不限于由第二设备执行，具体可由安装于第二设备中的硬件和/或软件执行。本实施例中，所述方法400至少可以包括如下步骤。
