具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也是旨在包括多数形式，除非上下文清楚地表示其它含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，例如，在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
下面，对本申请的应用场景进行说明：
图1示出了本申请一个示例性实施例提供的通信系统的框图，该通信系统可以包括：终端10和网络设备20。
终端10的数量通常为多个，每一个网络设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
接入网设备20是一种部署在接入网中用以为终端10提供无线通信功能的装置。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称 可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端10提供无线通信功能的装置统称为接入网设备。接入网设备20与终端10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备20的数量可以有多个，两个邻近的接入网设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的接入网设备20之间进行切换，也即与不同的接入网设备20建立连接。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
而随着移动通信技术的发展，提出了一种通感一体化技术，该通感一体化技术由通信系统和雷达系统实现，本申请可以通过该通感一体化技术实现感知与检测，以获取数据接收端的移动速度和/或距离。在通感一体化技术中，包括数据发送设备、数据接收设备和回波接收设备。而数据发送设备、数据接收设备和回波接收设备进行交互前，可以先确定每个数据接收设备和回波接收设备在相同的时域位置对应的多个子载波，本申请为方便描述，将确定子载波的设备统一以目标设备描述，数据接收设备和回波接收设备统一描述为传输设备。
在本申请实施例中，数据发送设备、数据接收设备和回波接收设备确定子载波后，可以基于子载波传输数据。其中，数据发送设备发送信号，回波接收设备可以接收数据发送设备发送的信息，而数据接收设备不仅接收该信号，还会对该信号进行反射，回波接收设备接收由数据接收设备反射的信号，并且回波接收设备还可以接收数据发送设备发送的信号，进而根据数据发送设备发送的信号和接收的数据接收设备反射的信号，确定数据接收设备的移动速度和/或距离。
例如，参见图2，该通信雷达一体化系统架构通过发送比特数据，对该比特数据进行串并转换和符号调制，调制后的信号会发送给雷达处理器，并且还会对调制后的信号进行快速傅里叶逆变换后，添加循环前缀后再进行并串转换，对转换后的信号进行数字信号到模拟信号的转换，发射给移动的目标设备，目标设备会对转换后的信号进行反射，接收设备对反射后的信号进行模拟信号到数字信号的转换，对转换后的信号去除循环前缀，再进行串并转化，再进行快速傅里叶变换，并且还会对变换后的信号进行并串转换，解调后得到比特数据， 而雷达处理器可以根据接收的两个信号确定目标设备的移动速度和/或距离。
在一些实施例中，上述所涉及的终端和接入网设备可以为通感一体化技术中的数据发送设备和数据接收设备，而雷达处理器为回波接收设备，也即是数据发送设备发送比特数据，雷达处理器和数据接收设备均接收数据发送设备对比特数据处理后的信号，并且数据接收设备还会反射数据发送设备发送的信号，则雷达处理器和数据发送设备还均可以接收数据接收设备反射的信号。
需要说明的是，数据发送设备可以向多个数据接收设备发送数据，而不同的数据接收设备在不同的子载波上接收数据发送设备发送的数据，因此对于数据发送设备、数据接收设备和回波接收设备来说，均需要确定每个数据接收设备的子载波，进而基于每个数据接收设备的子载波接收数据发送设备发送的数据。
下面，对本申请的通信雷达一体化系统的信号处理进行说明：基于OFDM(Orthogonal Frequency Division Multiplexing，正交频分复用)通信雷达一体化系统通过数据发送设备对信号散射和目标反射后，数据接收设备将接收信号分别传输到通信处理端与雷达处理端。OFDM时域发射信号表示为
Figure PCTCN2021141329-appb-000001
其中，S Tx()为OFDM频域符号，即为s(t)的傅里叶变换，N frame为一帧OFDM信号的总符号数，N c为子载波数，μ＝0,...,N frame-1为OFDM符号索引，n＝0,...,N c-1为子载波索引，f n表示对应的子载波频率，T OFDM＝T+T CP为OFDM符号周期，T为OFDM基础符号周期，T CP为循环前缀时间，rect()为矩形窗函数。
通信雷达一体化系统可对环境中的目标设备进行通信及感知探测，接收的信号出现多普勒频偏，其表达式为：
f D,radar＝2v rel/λ＝2v relf c/c
其中λ为波长，f c为载波频率，c为光速，且λ＝c/f c。
当OFDM信号的距离为R，由相关运动而引起的多普勒频移为f d的目标反射时，接收信号表示为：
Figure PCTCN2021141329-appb-000002
由发送信号和多普勒频移可得接收的调制符号为：
Figure PCTCN2021141329-appb-000003
对于一个距离通信雷达一体化系统为R的物体，所有反射OFDM符号的子载波数据间都将产生一个线性相移。假设物体是静止的，对于同一个OFDM符号，即同一时间点，距离信息R被包含在频率轴上的调制符号间的线性相移中。多普勒处理与距离处理相似。以相对速度v rel运动的目标设备反射的回波信号的多普勒频率是具有同样相对速度的通信信号的多普勒频率的两倍。对于同一个OFDM子载波，即同一频率点，相对速度信息v rel被包含在时间轴上的调制符号间的线性相移中。
图3示出了本申请一个示例性实施例提供的子载波确定方法的流程图，示例性的可以应用于如图2所示的目标设备中，以目标设备为数据发送设备为例，对本申请的方法进行说明，该方法包括以下内容中的至少部分内容：
步骤301：数据发送设备确定至少两个传输设备中每个传输设备在相同的时域位置对应的多个子载波。
其中，子载波用于进行数据传输，多个子载波中的相邻子载波之间的间隔为目标间隔，传输设备为数据接收设备和回波接收设备中的至少一种。在本公开实施例中，多个是指大于一个的任意数字，即：多个为大于等于2个。
在本申请实施例中，数据发送设备可以向至少两个传输设备发送数据，以便于基于发送的数据测量每个数据接收设备的移动速度和/或距离，而对于每个传输设备来说，该传输设备在相同的时域位置对应多个子载波，因此数据发送设备需要确定每个传输设备在相同的时域位置对应的多个子载波，并且这多个子载波中相邻的子载波之间的间隔为目标间隔，后续数据发送设备可以基于确定的多个子载波进行数据传输。
需要说明的是，本申请实施例仅是以目标设备为数据发送设备为例进行说明。而在另一实施例中，该目标设备还可以为数据接收设备，也即是数据接收设备确定至少两个传输设备中每个传输设备在相同的时域位置对应的多个子载波。
在本申请实施例中，传输设备在相同的时域位置对应多个子载波，而数据发送设备会根据多个子载波进行数据传输，数据接收设备也需要确定在相同的时域位置对应的多个子载波，并且这多个子载波中相邻的子载波之间的间隔为 目标间隔。
在另一实施例中，该目标设备还可以为回波接收设备，也即是回波接收设备确定至少两个传输设备中每个传输设备在相同的时域位置对应的多个子载波。
在本申请实施例中，回波接收设备在相同的时域位置对应多个子载波，而数据发送设备会根据多个子载波进行数据传输，因此回波接收设备为了能接收数据发送设备发送的数据以及数据接收设备反射的数据，也需要确定在相同的时域位置对应的多个子载波，并且这多个子载波中相邻的子载波之间的间隔为目标间隔。
本申请实施例提供了一种子载波确定方式，在相同的时域位置确定的多个子载波中，相邻的子载波之间的间隔为目标间隔，保证确定的用于进行数据传输的子载波的可靠性，并且相邻的子载波之间存在间隔，防止子载波之间的干扰，保证基于传输的数据确定数据接收设备的参数的准确性。

在本公开实施例中，子载波在相同的时域位置按照目标间隔分布是指：在相同的时域位置的多个等间隔分布的子载波；即，相邻的两个子载波之间距离该目标间隔。
在一些实施例中，接入网设备发送配置信息，该配置信息中包括子载波分配方式。
在一些实施例中，接入网设备可以向数据发送设备发送多个子载波分配方 式，则数据发送设备可以接收多个子载波分配方式。
步骤402：数据发送设备根据子载波分配方式，确定每个传输设备在相同的时域位置对应的多个子载波。其中多个子载波之间等间隔分布，其该间隔为目标间隔。
在本申请实施例中，数据发送设备接收到接入网设备发送的子载波分配方式后，即可根据该子载波分配方式确定每个传输设备在相同的时域位置对应的多个子载波按照目标间隔等间隔分布。
在一些实施例中，子载波分配方式承载在DCI(Downlink Control Information，下行控制信息)信令，或者子载波分配方式承载在MAC-CE(Medium Access Control-Control Element，媒体接入控制-控制单元)信令，或者子载波分配方式承载在RRC(Radio Resource Control，无线资源控制)信令。
在一些实施例中，接入网设备通过半静态信令指示子载波分配方式。在本申请实施例中，接入网设备通过发送的信令确定该信令指示的子载波分配方式。该信令为RRC信令。
在另一些实施例中，接入网设备通过动态信息指示子载波分配方式。在本申请实施例中，接入网设备通过MAC-CE信令或DCI信令指示子载波分配方式。
需要说明的是，本申请实施例仅是以接入网设备指示子载波分配方式为例进行说明。而在另一实施例中，数据发送设备接收接入网设备发送的多个子载波分配方式后，从多个子载波分配方式中确定使用的子载波分配方式，再根据自身确定使用的子载波分配方式确定每个数据接收设备的分布情况。
本申请实施例提供的方法，数据发送设备根据接入网设备发送的子载波分配方式即可确定每个数据接收设备的子载波分布情况，保证数据发送设备确定的用于进行数据传输的子载波的可靠性，并且相邻的子载波之间存在间隔，防止子载波之间的干扰，保证基于传输的数据确定数据接收设备的参数的准确性。

步骤502：数据发送设备根据该子载波分配方式，确定每个数据接收设备在 相同的时域位置对应的多个子载波中的两个相邻的子载波之间的间隔为目标间隔。
其中，每个传输设备在相同的时域位置对应的多个子载波分布情况由通信协议约定，因此数据发送设备可以直接根据通信协议，确定子载波分配方式，进而确定每个传输设备在相同的时域位置对应的多个子载波按照目标间隔分布。
在一些实施例中，通信协议约定了每个传输设备在相同的时域位置对应的多个子载波中每个子载波的起始位置以及目标间隔，因此根据每个传输设备对应的子载波的起始位置以及目标间隔，确定每个传输设备对应的多个子载波。
本申请实施例提供的方法，数据发送设备根据通信协议约定的子载波分配方式即可确定每个传输设备的子载波分布情况，保证数据发送设备确定的用于进行数据传输的子载波的可靠性，并且相邻的子载波之间存在间隔，防止子载波之间的干扰，保证基于传输的数据确定数据接收设备的参数的准确性。
第三种：根据核心网设备发送的子载波分配方式确定子载波，例如，参见图6，该方法包括：

在本公开实施例中，如果该数据发送设备直接连接到核心网设备，则核心网设备可以直接向数据发送设备发送子载波分配方式；如果数据发送设备没有直接连接到核心网设备，则核心网设备可以通过其他任何恰当的设备，将该子载波分配方式发送给数据发送设备。在本公开实施例中，这些方式都被统称为：数据发送设备接收核心网设备发送的子载波分配方式。
在本申请实施例中，核心网设备可以直接或间接(通过其他设备)向各个设备发送的子载波分配方式，该子载波分配方式指示子载波在相同个时域位置按照目标间隔分布，则数据发送设备接收到核心网设备发送的子载波分配方式，通过该子载波分配方式指示子载波的分配情况。

在一些实施例中，子载波分配方式承载在DCI信令，或者子载波分配方式承载在MAC-CE信令，或者子载波分配方式承载在RRC信令。
在一些实施例中，核心网设备通过半静态信令指示子载波分配方式。在本申请实施例中，核心网设备通过发送的信令确定该信令指示的子载波分配方式。该信令为RRC信令。
在另一些实施例中，核心网设备通过动态信息指示子载波分配方式。在本申请实施例中，核心网设备通过MAC-CE信令或DCI信令指示子载波分配方式。

需要说明的是，本申请实施例仅是以数据发送设备向数据接收设备发送子载波分配方式为例进行说明。

步骤803：回波接收设备根据子载波分配方式，确定每个传输设备在相同的时域位置对应的多个子载波中的两个相邻的子载波之间的间隔为目标间隔。

即，在一种可能的实现方式中：

需要说明的是，上述图7和图8实施例仅是以数据发送设备向数据接收设备和回波接收设备发送子载波分配方式为例进行说明。而在另一实施例中，还可以由数据接收设备确定子载波分配方式，再由数据接收设备向数据发送设备和回波接收设备发送子载波分配方式，其中数据接收设备向数据发送设备和回波接收设备发送子载波分配方式的过程与上述图7和图8所示的实施例的流程类似，在此不再赘述。
另外，在另一实施例中，还可以由回波接收设备确定子载波分配方式，再由回波接收设备向数据发送设备和数据接收设备发送子载波分配方式，其中回波接收设备向数据发送设备和数据接收设备发送子载波分配方式的过程与上述图7和图8所示的实施例的流程类似，在此不再赘述。
在图3所示的实施例的基础上，目标间隔根据数据接收设备的数量确定，也就是数据接收设备的数量不同，确定的目标间隔也不同。
在一些实施例中，目标间隔为数据接收设备的数量与1的差值。
在本申请实施例中，至少两个数据接收设备在相同的时域位置均需要占用子载波，则按照每个数据接收设备对相同的时域位置上的多个子载波进行分配，以使每个数据接收设备分配的多个子载波中相邻子载波之间的距离为目标间隔。
其中，目标间隔为数据接收设备的数量与1的差值。
对于任一数据接收设备，该数据接收设备在频域资源中占据的子载波具有相等的频率间隔，即相邻频域信号的频率间隔为目标间隔。假设数据接收设备占据频域资源中全部N个子载波中的N u个子载波，且N u个子载波构成一个集合N，令N(s)表示集合的第s个元素。假设该数据接收设备占有的子载波的中心频率为f(i)，其中i＝N(1)，N(2)…，N(N u)。当采取子载波等间隔分配方案时，可得f(i+1)-f(i)＝Δf，其中Δf为目标间隔，且Δf为数据接收设备的数量与1的差值。
需要说明的是，上述实施例仅是以一个数据接收设备对相邻的子载波的间隔进行说明。而在另一实施例中，对于至少两个数据接收设备来说，一个数据接收设备对应的相邻的两个子载波之间的间隔是其他所有数据接收设备对应的一个子载波，也就是目标间隔是其他所有数据接收设备对应的一个子载波的数量的和。
例如，以一个时域位置包括1024个子载波，数据接收设备为4个，则对于第一个数据接收设备来说，每个时域位置上的1024个子载波中的第4n+1个子载波，n＝0,1,2…255，对于第二个数据接收设备来说，每个时域位置上的1024个子载波中的第4n+2个子载波，n＝0,1,2…255，对于第三个数据接收设备来说，每个时域位置上的1024个子载波中的第4n+3个子载波，n＝0,1,2…255，对于第四个数据接收设备来说，每个时域位置上的1024个子载波中的第4n+4个子载波，n＝0,1,2…255。
对于第一个数据接收设备，目标间隔为第二个数据接收设备、第三个数据接收设备和第四个数据接收设备分别对应的一个子载波。例如，以第一个数据接收设备的第1个子载波和第5个子载波为例，第1个子载波和第5个子载波之间间隔的是第二个数据接收设备的第2个子载波、第三个数据接收设备的第3个子载波和第四个数据接收设备的第4个子载波。而对于第二个数据接收设备的第2个子载波和第6个子载波为例，第2个子载波和第6个子载波之间间隔的第三个数据接收设备的第3个子载波、第四个数据接收设备的第4个子载波和第一个数据接收设备的第5个子载波，以此类推，每个数据接收设备的相邻两个子载波之间均间隔其他所有数据接收设备的一个子载波。
在此情况下，参见图9，对于第一个终端来说，其他终端的距离和速度为图示中的黑色点对应的距离和速度。
例如，以一个时域位置包括1024个子载波，数据接收设备为4个，则对于 第一个数据接收设备来说，每个时域位置上的1024个子载波中的第4n+i个子载波，n＝0,1,2…255，对于第二个数据接收设备来说，每个时域位置上的1024个子载波中的第4n+j个子载波，n＝0,1,2…255，对于第三个数据接收设备来说，每个时域位置上的1024个子载波中的第4n+k个子载波，n＝0,1,2…255，对于第四个数据接收设备来说，每个时域位置上的1024个子载波中的第4n+l个子载波，n＝0,1,2…255，其中，i,j,k,l∈{1,2,3,4}且i、j、k、l各不相同，对于每个时域位置来说，i、j、k、l随机从1、2、3、4中确定，但i、j、k、l各不相同。
对于第一个数据接收设备，目标间隔为第二个数据接收设备、第三个数据接收设备和第四个数据接收设备分别对应的一个子载波。例如，在一个时域位置上，i取2、j取1、k取4和l取3为例，以第一个数据接收设备的第2个子载波和第6个子载波为例，第2个子载波和第6个子载波之间间隔的是第四个数据接收设备的第3个子载波、第三个数据接收设备的第4个子载波和第二个数据接收设备的第5个子载波。而对于第四个数据接收设备的第3个子载波和第7个子载波为例，第3个子载波和第7个子载波之间间隔的第三个数据接收设备的第4个子载波、第二个数据接收设备的第5个子载波和第一个数据接收设备的第6个子载波，以此类推，每个数据接收设备的相邻两个子载波之间均间隔其他所有数据接收设备的一个子载波。
在此情况下，参见图10，对于第一个终端来说，其他终端的距离和速度为图示中的黑色点对应的距离和速度。
在图3所示的实施例的基础上，数据接收设备为终端，回波接收设备为接入网设备或终端，数据发送设备为接入网设备或终端。
在一些实施例中，数据发送设备和回波接收设备可以为同一个设备。
例如，数据发送设备和回波接收设备均为接入网设备。
又例如，数据发送设备和回波接收设备均为终端，而数据发送设备和回波接收设备的终端与数据接收设备的终端不是同一个终端。
需要说明的是，数据发送设备和回波接收设备为同一设备的情况下，该通感一体化系统为主动式雷达系统，该数据发送设备发送比特数据给数据接收设备，数据接收设备作为接收机完成通信功能。数据发送设备发送比特数据照射在数据接收端上产生的回波信号回传至回波接收设备(即数据发送设备)，回波接收设备通过雷达处理器对数据接收设备进行速度和距离等信息探测，完成 雷达功能。
在另一些实施例中，数据发送设备和回波接收设备为不同的设备。
例如，数据发送设备为接入网设备1，数据接收设备为终端，回波接收设备为接入网设备2或者接入网设备集合。
又例如，数据发送设备为终端1，数据接收设备为终端2，回波接收设备为终端3或者终端结合。
又例如，数据发送设备为终端1，数据接收设备为终端2，回波接收设备为接入网设备或者接入网设备集合。
需要说明的是，数据发送设备和回波接收设备为不同的设备的情况下，该通感一体化系统为被动式雷达系统，数据发送设备和回波接收设备为不相同的设备，且可有多个回波接收设备。数据发送设备发送比特数据给数据接收设备，数据接收设备作为接收机完成通信功能。数据发送设备发送比特数据照射在数据接收设备上产生的回波信号回传至回波接收设备，回波接收设备通过雷达处理器对数据接收设备进行速度和距离等信息探测，完成雷达功能。
