Description

数据传输方法和数据传输装置
本申请要求于2022年04月19日提交中国国家知识产权局、申请号为202210409826.8、申请名称为“数据传输方法和数据传输装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信领域，尤其涉及一种数据传输方法和数据传输装置。
背景技术
随着无线通信应用场景的日益丰富以及半导体器件技术的飞速发展，未来的无线通信设备可能具备一定的感知能力。具有感知能力的终端设备可以向其周围发射波束。终端设备发送的波束遇到障碍之后会被反射。终端设备接收反射的波束后，采用图像相关的算法，对波束数据进行压缩，并向网络设备发送压缩后的波束数据。网络设备接收压缩后的波束数据，可以根据该压缩后的波束数据构建环境信息，例如可以构建障碍物的形状以及计算障碍物到终端设备的距离等。
但是，网络设备基于终端设备发送的采用图像压缩类算法进行压缩后的波束数据构建的环境信息准确性较低，且终端设备需要发送的数据量也较大，需要占用大量空口资源。
因此，如何提高网络设备基于终端设备感知的波束数据构建的环境信息的准确性以及降低传输的数据量，成为亟待解决的技术问题。
发明内容
本申请提供了一种数据传输方法和数据传输装置，有利于提高环境构建的准确性，且降低传输的数据量，从而降低占用的空口资源。

感知物体是被感知的环境物体，例如，障碍物。感知物体可以理解为感知设备所处环境中的任意物体，也可以称为环境物体，本申请对此不作限定。
感知设备为具有感知能力的终端设备。感知设备可以发送波束信号，该波束信号可以被感知物体反射。

第一数据集可以是来自于感知物体的至少一个波束信号的采样数据，一个波束信号可以采集多个数据。第一数据集可以以矩阵的形式表示，但本申请实施例并不限于此。
第一数据集可以是频域的数据集，也可以是时域的数据集，还可以是空域的数据集，本申请实施例对此不作限定。
若第一数据集是频域的数据集，第二数据集可以是第一数据集变换后的数据集。终端设备可以对第一数据集进行预处理，得到第一数据集变换后的数据集。若第一数据集是时域的数据集，或者，第一数据集是空域的数据集，则第二数据集可以是第一数据集。
第二数据集中的数据具有优先级，第一目标数据包括第二数据集中优先级大于或等于第一预设门限的数据。其中，第一目标数据可以包括至少一个数据，第一预设门限可以是优先级的等级。第一位置数据包括第一目标数据在第二数据集中的位置信息。
本申请提供的数据传输方法，将第二数据集中优先级大于或等于第一预设门限的数据确定为第一目标数据，将第一目标数据在第二数据集的位置信息确定为第一位置信息，舍弃优先级小于第一预设门限的目标数据和其对应的位置数据，通过此方式对第一数据集进行压缩，可以尽可能保证关键信息不丢失，有利于提高环境构建或者电磁成像的准确性。
结合第一方面，在第一方面的某些实现方式中，优先级是根据预设参量确定的。
该预设参量可以是协议约定的，也可以是终端设备确定的，还可以是网络设备确定，本申请实施例对此不作限定。
若预设参量是协议约定的，终端设备可以根据协议约定的参量设置第二数据集中数据的优先级，可以节省信令开销，提高通信效率。
若预设参量是终端设备确定的，终端设备可以自主确定预设参量，灵活性更强，应用范围更广。
若预设参量是网络设备确定的，终端设备只需根据网络设备的预设参量设置第二数据集中数据的优先级，可以节省处理资源，对终端设备的要求较低。

在又一种可能的实现方式中，树形数据结构可以为四叉树和四叉树混合二叉树。终端设备可以先分别使用四叉树和四叉树混合二叉树对第一位置数据进行压缩，然后比较两种方式的压缩率，选择压缩率较高的压缩方式所得到的压缩后的第一位置数据。
本申请提供的数据传输方法，将第一位置数据进行压缩后再发送，可以减少传输的数据量，降低传输所使用的资源。
结合第一方面，在第一方面的某些实现方式中，第一位置数据包括第一目标数据在第二数据集中所处区域的边界信息。
当第一位置数据在第二数据集中的位置呈现聚集性的特点时，终端设备可以将第一目标数据在第二数据集中所处区域的边界信息确定为第一位置数据。应理解，第一位置数据在第二数据集中的位置呈现聚集性的特点，即第一位置数据在第二数据集中的位置比较集中，可以聚集在一个或者多个区域。
第二数据集包括多个波束的采样数据时，若第二数据集中每个波束的采样数据均具有聚集性，且不同的波束的位置数据的聚集性不同，终端设备可以使用一维区间框出每个波束的位置数据所在的区域。若第二数据集中每个波束的采样数据均具有聚集性，且不同的波束的位置数据的聚集性相同，则终端设备可以使用二维区域框出多个波束的位置数据所在的区域。终端设备可以将一维区间或者二维区域的边界对应的位置信息确定为第一位置数据。
本申请提供的数据传输方法，通过第一目标区域所处区域的边界信息确定为第一位置数据，通过比较少的信息比特表示第一目标区域在第二数据集中的位置信息，可以降低传输的数据量，节省传输资源。
结合第一方面，在第一方面的某些实现方式中，所处区域的边界信息包括多个区域的边界信息。
结合第一方面，在第一方面的某些实现方式中，第一信号中还携带第二数据集的目标数值，目标数值包括总功率、总能量、平均功率、平均能量、功率方差、或者能量方差中的至少一个。
第二数据集可以包括一个或者多个波束的采样数据。当第二数据集包括一个波束的采样数据时，终端设备计算该波束的所有采样数据的目标数值，即总功率、总能量、平均功率、平均能量、功率方差、或者能量方差中的至少一个。当第二数据集包括多个波束的采样数据时，终端设备可以计算该多个波束中每个波束的所有采样数据的目标数值，即总功率、总能量、平均功率、平均能量、功率方差、或者能量方差中的至少一个。
本申请提供的数据传输方法，通过目标数值提高第一目标数据和第一位置信息的可信度，可以使第二数据集达到有限压缩的同时，还能在接收端达到较好的环境重构效果。
结合第一方面，在第一方面的某些实现方式中，在终端设备发送第一信号之前，方法还包括：终端设备接收第一资源指示信息，第一资源指示信息用于指示第一时频 资源；终端设备发送第一信号，包括：终端设备在第一时频资源上发送第一信号。
第一时频资源用于承载第一信号，终端设备可以在第一时频资源上发送第一信号。
第一时频资源所承载的数据量可以小于第二目标数据(其中包括第一目标数据)的数据量与第二位置数据(其中包括第一位置数据)的数据量之和，也可以是等于第一目标数据的数据量与第一位置数据的数据量之和，还可以是大于第一目标数据的数据量与第一位置数据的数据量之和，本申请实施例对此不作限定。

当第一时频资源所承载的数据量小于第二目标数据的数据量与第二位置数据的数据量之和时，第一时频资源不能承载所有的第二目标数据和第二位置数据，但可以承载部分目标数据和部分位置数据。终端设备可以根据优先级的高低顺序和第一时频资源确定第一目标数据和第一位置数据，即可以先发送优先级级别高的数据，且这些数据的数据量小于或等于第一时频资源所承载的数据量。第一目标数据的优先级在第二目标数据中的优先级较高，且第一目标数据的数据量与第一位置数据的数据量之和小于或等于第一时频资源所承载的数据量。
需要说明的是，可选的，有些情况下，第一目标数据的数据量与第一位置数据的数据量之和虽小于第一时频资源所承载的数据量，但不足以承载其他优先级的数据，则可对第一目标数据和第一位置数据补零，以使其等于第一时频资源所承载的数据量。
若第二目标数据包括多个优先级的数据，第一目标数据可以是第二目标数据中的优先级较高的数据，若第二目标数据和第二位置数据包括一个优先级，第一目标数据可以是该优先级中的部分数据。
本申请提供的数据传输方法，通过第一时频资源的数据量确定传输的数据，增加了数据传输的灵活性。
结合第一方面，在第一方面的某些实现方式中，上述方法还包括：终端设备发送第一指示信息，第一指示信息用于指示数据传输未完成；或者，终端设备发送第二指示信息，第二指示信息用于指示数据传输完成。
第二目标数据中除第一目标数据之外的目标数据，第二位置数据中除第一位置数据之外的位置数据，是否需要继续传输，可以由终端设备确定。若第一目标数据和第一位置信息未达到压缩精度的要求，终端设备可以确定继续传输数据，并发送第一指示信息，第一指示信息用于指示数据传输未完成。若第二目标数据和第二位置信息已经达到了压缩精度的要求，终端设备可以确定不再继续传输数据，并发送第二指示信息，该第二指示信息用于指示数据传输完成。
本申请提供的数据传输方法，当第一时频资源所承载的数据量小于第二目标数据的数据量与第二位置数据的数据量之和时，可以在第一时频资源传输部分目标数据和部分位置数据，终端设备可以自主确定是否继续传输数据，增加了终端设备的能动性。

为便于理解本申请实施例，首先结合图1对适用于本申请实施例的通信系统100进行详细说明。
该通信系统100包括车辆101和网络设备102。车辆101具有感知能力，可以向其周围发射波束。车辆101发射的波束遇到障碍物之后会被反射。车辆101接收反射的波束后，采用图像相关的算法例如离散余弦变换(Discrete Cosine Transform，DCT)或者小波变换等算法，对波束数据进行压缩，并向网络设备102发送压缩后的波束数据。网络设备102接收压缩后的波束数据，可以根据该压缩后的波束数据构建环境信息，例如可以构建障碍物的形状以及计算障碍物到终端设备的距离等。
但是，本领域技术人员发现，网络设备102基于车辆101发送的波束数据构建的环境信息准确性较低。经研究发现，车辆101之所以使用图像相关的算法进行压缩，是因为反射的波束对应的数据可以表示成二维浮点数矩阵的形式。这种压缩方式，未考虑环境构建的特点，会导致环境构建的关键信息丢失，进而造成环境构建的准确性低。
有鉴于此，本申请实施例提供一种数据传输方法和数据传输装置，有利于提高环 境构建的准确性。
为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一数据集和第二数据集是为了区分不同的数据集，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性地”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性地”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性地”或者“例如”等词旨在以具体方式呈现相关概念。
此外，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b和c中的至少一项(个)，可以表示：a，或b，或c，或a和b，或a和c，或b和c，或a、b和c，其中a，b，c可以是单个，也可以是多个。
另外，本申请实施例中涉及的“协议”可以是指通信领域的标准协议，例如可以包括长期演进(long term evolution，LTE)协议、新无线(new radio，NR)协议、6G协议以及应用于未来的通信系统中的相关协议，本申请对此不做限定。
在下文示出的实施例中，“协议约定”可以是协议定义或者预先定义。其中，“协议约定”可以通过在设备(例如，包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现，本申请对于其具体的实现方式不做限定。
下面将详细说明本申请提供的各个实施例。
本申请实施例以终端设备和网络设备为例进行描述，应理解，终端设备可以替换为能够实现与终端设备类似的功能的装置或芯片，网络设备也可以替换为能够实现与网络设备类似的功能的装置或芯片，本申请实施例对其名称不作限定。
图2示出了本申请实施例提供的数据传输方法200的示意性流程图。该方法可以应用于上述图1所述的通信系统100，但本申请实施例并不限于此。该方法200可以由终端设备执行，例如，上述车辆101。
如图2所示，该方法200可以包括：
S201、终端设备获取第一数据集，第一数据集包括来自于感知物体的波束信号的采样数据。
感知物体是被感知的环境物体，例如，障碍物。感知物体可以理解为感知设备所处环境中的任意物体，也可以称为环境物体，本申请实施例对此不作限定。
感知设备为具有感知能力的终端设备，例如上述车辆101。感知设备可以发送波束信号，该波束信号可以被感知物体反射。
感知物体的波束信号用于实现感知任务，例如，环境构建或者电磁成像。感知物体的波束信号可以是感知设备发射而被感知物体反射回来的波束信号，也可以是感知 设备接收到的波束信号，还可以是感知物体发射的，本申请实施例对此不作限定。
可选地，感知物体的波束信号是由感知物体反射的。终端设备可以具有感知能力，可以向周围发送波束，波束可以被感知物体反射，得到反射的波束信号。终端设备也可以不具有感知能力，可以接收其它具有感知能力的终端设备的波束信号的采样数据。
第一数据集可以是来自于感知物体的至少一个波束信号的采样数据，一个波束信号可以采集多个数据。
示例性地，第一数据集可以是来自于感知物体的256个波束信号的采样数据，一个波束信号可以采集1036个数据，则第一数据集可以包括256*1036个数据。
第一数据集可以以矩阵的形式表示，但本申请实施例并不限于此。示例性地，若第一数据集包括256*1036个数据，则第一数据集可以以256行1036列的矩阵表示。
第一数据集也可以称为原生数据，本申请实施例对此不作限定。
第一数据集可以是频域的数据集，也可以是时域的数据集，还可以是空域的数据集，本申请实施例对此不作限定。

若第一数据集是频域的数据集，第二数据集可以是第一数据集变换后的数据集。终端设备可以对第一数据集进行预处理，得到第一数据集变换后的数据集。例如，终端设备可以对第一数据集进行逆快速傅里叶变换(Inverse Fast Fourier Transform，IFFT)，将频域转换为时域，得到时域的数据集，即得到第二数据集。
若第一数据集是时域的数据集，或者，第一数据集是空域的数据集，则第二数据集可以是第一数据集。
第二数据集中的数据具有优先级，第一目标数据包括第二数据集中优先级大于或等于第一预设门限的数据。其中，第一目标数据可以包括至少一个数据，第一预设门限可以是优先级的等级。第一位置数据包括第一目标数据在第二数据集中的位置信息。
例如，第二数据集以256行1036列的矩阵表示，每一行数据可以包括多个优先级的数据，例如，每一行数据包括5个优先级的数据，分别为第一优先级的数据、第二优先级的数据、第三优先级的数据、第四优先级的数据以及第五优先级的数据，且第一优先级、第二优先级、第三优先级、第四优先级以及第五优先级是从高到低排序的，第一预设门限可以是第三优先级。第二数据集中每一行数据中优先级大于或等于第三优先级的数据均为第一目标数据，即第一目标数据包括第一优先级的数据、第二优先级的数据以及第三优先级的数据。第一位置数据包括第一目标数据在第二数据集中的位置信息，即第一优先级的数据、第二优先级的数据以及第三优先级的数据在该矩阵中的位置信息。
又如，图3示出了一种第二数据集的示意图。第二数据集以8行10列的矩阵进行说明，每一行数据可以包括3个优先级的数据，第一优先级的数据为填充黑色的数据，第二优先级的数据为填充图案的数据，第三优先级的数据为填充白色的数据。第一优先级、第二优先级以及第三优先级是从高到低排序的。第一预设门限可以是第一优先 级，终端设备可以将第一优先级对应的数据，即填充黑色的数据确定为第一目标数据，将填充黑色的数据在第二数据集中的位置信息确定为第一位置数据。
再如，图4示出了一种第二数据集的示意图。在电磁成像场景中，第二数据集可以为图像对应的数据，图像中一般存在目标物体，终端设备可以通过第一预设门限将目标物体对应的数据确定为第一目标数据，将第一目标数据在图像的位置确定为第一位置数据。
第一预设门限可以是终端设备确定的，也可以是网络设备确定的，本申请实施例对此不作限定。第一预设门限可以是基于时频资源和/或压缩精度确定的，本申请实施例并不限于此。
可选地，若第一预设门限是基于压缩精度确定的，终端设备可以将第二数据集中满足压缩精度的优先级的数据确定为第一目标数据，将第一目标数据在第二数据集中的位置确定为第一位置数据。其中，满足压缩精度的优先级的数据中最低的优先级级别为第一预设门限。
终端设备可以将第一目标数据和第一位置数据承载在第一信号上，发送第一信号以传输第一目标数据和第一位置数据。网络设备可以获取第一信号，得到第一目标数据和第一位置数据。
S203、网络设备根据第一目标数据和第一位置数据，重构第一数据集。
网络设备可以根据第一目标数据和第一位置数据，得到第二数据集，进而重构第一数据集，以用于实现感知任务，例如，环境构建或者电磁成像。
本申请实施例提供的数据传输方法，将第二数据集中优先级大于或等于第一预设门限的数据确定为第一目标数据，将第一目标数据在第二数据集的位置信息确定为第一位置信息，舍弃优先级小于第一预设门限的目标数据和其对应的位置数据，通过此方式对第一数据集进行压缩，可以尽可能保证关键信息不丢失，有利于提高环境构建或者电磁成像的准确性。
作为一个可选的实施例，上述第二数据集中数据的优先级可以是根据预设参量确定的。该预设参量可以是协议约定的，也可以是终端设备确定的，还可以是网络设备确定，本申请实施例对此不作限定。
若预设参量是协议约定的，终端设备可以根据协议约定的参量设置第二数据集中数据的优先级，可以节省信令开销，提高通信效率。
若预设参量是终端设备确定的，终端设备可以自主确定预设参量，灵活性更强，应用范围更广。
若预设参量是网络设备确定的，终端设备只需根据网络设备的预设参量设置第二数据集中数据的优先级，可以节省处理资源，对终端设备的要求较低。
可选地，预设参量可以为功率阈值、能量阈值、数量阈值、或者数据种类中的一种或多种。
在第一种可能的实现方式中，第二数据集中数据的优先级可以根据功率阈值确定。功率阈值可以为一个数值，也可以为多个数值，本申请实施例对此不作限定。当功率阈值为一个数值时，终端设备可以将第二数据集中的数据分为两个优先级的数据，一个优先级的数据是高于功率阈值的数据，另一个优先级的数据是低于功率阈值的数据。 当功率阈值为多个数值时，终端设备可以将第二数据集数据分为多个优先级的数据。
其中，示例性的，当功率阈值为一个数值时，该功率阈值可以是平均功率，该平均功率可以是第二数据集中数据的最大功率和最小功率的均值。当功率阈值为多个数值，例如n时，终端设备可以将第二数据集数据分为n+1个优先级的数据。
若第二数据集中数据的最大功率为Pmax和最小功率为Pmin，终端设备可以通过公式将最大功率Pmax和最小功率Pmin平均分为n+1份，第一优先级的数据可以是小于最大功率Pmax，但大于或等于Pmax-delta的数据，第二优先级的数据可以是小于最大功率Pmax-delta，但大于或等于Pmax-2*delta的数据，第三优先级的数据可以是小于最大功率Pmax-delta，但大于或等于Pmax-2*delta的数据，依次类推，第n+1优先级的数据可以是小于最大功率Pmax-n*delta，但大于或等于Pmax-(n+1)*delta(即Pmin)的数据。当然，阈值也可以按照需要非均匀的设置，在此不做赘述。
示例性地，第二数据集以256行1036列的矩阵表示，第二数据集中的数据在时域中，可以得到每一个数据的功率。终端设备可以根据功率阈值逐行对数据设置优先级。当功率阈值为两个数值，且分别为阈值1和阈值2(阈值1大于阈值2)时，终端设备可以将第二数据集中的数据按照这两个阈值分为三个优先级的数据，该三个优先级的数据可以包括第一优先级的数据、第二优先级的数据以及第三优先级的数据，第一优先级的数据可以为大于阈值1的数据，第二优先级的数据可以为小于阈值1但大于阈值2的数据，第三优先级的数据可以为小于阈值2的数据。
在第二种可能的实现方式中，第二数据集中数据的优先级可以根据能量阈值确定。功率阈值可以为一个数值，也可以为多个数值，本申请实施例对此不作限定。能量阈值的方案与上述功率阈值的方案相似，此处不再赘述。
在第三种可能的实现方式中，第二数据集中数据的优先级可以根据数量阈值确定。
数量阈值即数据量阈值，终端设备可以设置每一个优先级的数据量，通过数据量确定第二数据集中数据的优先级。
在第四种可能的实现方式中，第二数据集中数据的优先级可以根据数据种类确定。
示例性地，在上述图4所示的场景中，数据种类可以包括目标物体对应的数据和非目标物体对应的数据，目标物体对应的数据可以为优先级高的数据，非目标物体对应的数据可以为优先级低的数据。
在上述四种可能的实现方式中，对于第二数据集，终端设备可以按照时域(或称时延域)采样点的能量或功率大小对第二数据集中的数据设置优先级，或者对于电磁成像数据，终端设备可以按照空间域整个波束对应的数据的总能量或总功率第二数据集中的数据设置优先级。
预设参量可以为功率阈值、能量阈值、数量阈值、或者数据种类中的多种。
示例性地，在上述图4所示的场景中，终端设备可以先根据数据种类，将目标物体对应的数据确定为优先级高的数据，将非目标物体对应的数据确定为优先级低的数据，然后再根据功率阈值将目标物体对应的数据分为不同的优先级。
作为一个可选的实施例，上述S102中的第一信号中可以携带第一目标数据和压缩后的第一位置数据，压缩后的第一位置数据是根据树形数据结构对第一位置数据进行压缩得到的。
终端设备在确定第一目标数据和第一位置数据之后，可以根据树形数据结构对第一位置数据进行压缩，得到压缩后的第一位置数据，然后通过第一信号传输第一目标数据和压缩后的第一位置数据。
本申请实施例提供的数据传输方法，可以将第一位置数据进行压缩后再发送，可以减少传输的数据量，降低传输所使用的资源。
可选地，上述树形数据结构可以包括四叉树和/或四叉树混合二叉树，还可以是八叉树或者更高阶的树形数据结构。
在一种可能的实现方式中，树形数据结构可以为四叉树，终端设备可以根据四叉树对第一位置数据进行压缩，得到压缩后的第一位置数据。第二数据集可以使用位图(bitmap)的形式表示，第一位置数据在位图中的值为1，终端设备可以根据四叉树对位图进行压缩，以使用较少的比特数传输第一位置数据。
在环境重构的场景中，第一位置数据对应的位图具有高度的稀疏性并且非零位置在空间上呈现一定的聚集特性，因此可以使用四叉树对其进行有效的压缩。
若位图的维度为m行n列，终端设备可以先对其进行扩充，扩充为2L行2L列的位图。其中，L可以通过以下公式确定：
终端设备可以根据四叉树对新的位图进行逐层展开，若四叉树某层的某个节点对应的所有位置都为零，则该节点为叶节点，且其值为零，并停止向下展开。若四叉树某层的某个节点对应的位置包括不为零的位置，则继续向下展开。
示例性地，图5示出了一种位图的示意图。如图5中的a所示，第二数据集以4行7列的位图表示，其中，填充黑色的区域为第一位置数据，对应的数值为1。填充白色的区域对应的数值为0。
终端设备可以先计算扩充的维度，m＝4，对4取log后再取整，得到lm＝2，n＝7，对7取log后再取整，得到ln＝3，在lm和ln中取最大值，得到L＝3，2L＝8，则扩充后的位图的维度是8行8列的位图。终端设备可以在4行7列的位图上，向下用0填充4行，再向左用0填充1列，得到8行8列的位图，如图5中的b所示。
图6示出了一种基于四叉树的压缩方法的示意图。如图6所示，第一层：终端设备对8行8列的位图进行四叉树展开。第二层：终端设备将第一层的8行8列的位图分为4个象限，每个象限为4行4列的位图，第一象限和第二象限的位图包括数值1，第三象限和第四象限的位图均为0，则第一象限和第二象限的位图继续向下展开，第三象限和第四象限的位图停止向下展开。
第三层：终端设备将第二层的第一象限的4行4列的位图分为4个象限，每个象限为2行2列的位图，第一象限的位图包括数值1，第二象限、第三象限以及和第四象限的位图均为0，则第一象限的位图继续向下展开，第二象限、第三象限以及第四象限的位图停止向下展开。同理，终端设备将第二层的第二象限的4行4列的位图分为4个象限，每个象限为2行2列的位图，第一象限的位图、第二象限以及第四象限的位图均为0，第三象限包括数值1，则第三象限的位图继续向下展开，第一象限、第 二象限以及第四象限的位图停止向下展开。
第四层：终端设备将第三层的第一象限的2行2列的位图分为4个象限，每个象限为1行1列的位图，第一象限的位图、第二象限以及第三象限的位图均为0，第四象限包括数值1。终端设备将第三层的第三象限的2行2列的位图分为4个象限，每个象限为1行1列的位图，第一象限的位图和第二象限均为0，第三象限和第四象限包括数值1。
通过四叉树的方式，第一层需要1个比特，第二层需要4个比特，第三层需要8个比特，第四层需要8个比特，则终端设备共需要1+4+8+8＝21个比特传输第一位置数据，而在压缩之前，终端设备共需要4*7＝28比特的传输第一位置数据，故通过四叉树的方式，终端设备可以降低28-21＝7个比特。
需要说明的是，此示例的维度较小，节省的比特数相对较少，在实际使用中，第二数据集的维度一般较大且第一位置数据较稀疏时，可以节省的比特数较多。
可选地，终端设备可以判断压缩后的第一位置数据是否达到压缩要求，若压缩后的第一位置数据达到了压缩要求，则可以进行传输，若压缩后的第一位置数据未达到压缩要求，则可以使用其他压缩方法(例如，自适应算术码)再次对其进行压缩，直至达到压缩要求。
在另一种可能的实现方式中，树形数据结构可以为四叉树混合二叉树，终端设备可以根据四叉树混合二叉树对第一位置数据进行压缩，得到压缩后的第一位置数据。
位图的维度为m行n列，当m和n的数值相差较大时，例如，m＝288，n＝1301，使用四叉树混合二叉树可以进一步提高压缩效率。
若位图的维度为m行n列，终端设备可以先对其进行扩充，扩充为2lm行2ln列的位图。其中，lm和ln可以通过以下公式确定：
终端设备可以根据四叉树对新的位图进行逐层展开，若四叉树某层的某个节点对应的所有位置都为零，则该节点为叶节点，且其值为零，并停止向下展开。若四叉树某层的某个节点对应的位置包括不为零的位置，则继续向下展开。当四叉树展开到某一层的时候，已经不能通过四叉树进行进一步划分，但可以通过二叉树进行进一步划分，此时在四叉树的基础上以二叉树的形式做进一步展开。
示例性地，图7示出了一种位图的示意图。如图7中的a所示，第二数据集以4行7列的位图表示，其中，填充黑色的区域为第一位置数据，对应的数值为1。填充白色的区域对应的数值为0。
终端设备可以先计算扩充的维度，m＝4，对4取log后再取整，得到lm＝2，n＝7，对7取log后再取整，得到ln＝3，则扩充后的位图的维度是4行8列的位图。终端设备可以在4行7列的位图上，向左用0填充1列，得到4行8列的位图，如图7中的b所示。
图8示出了一种基于四叉树混合二叉树的压缩方法的示意图。如图8所示，第一层：终端设备对4行8列的位图进行四叉树展开。第二层：终端设备将第一层的4行8列的位图分为4个象限，每个象限为2行4列的位图，第一象限和第四象限的位图 包括数值1，第二象限和第三象限的位图均为0，则第一象限和第四象限的位图继续向下展开，第二象限和第三象限的位图停止向下展开。
第三层：终端设备将第二层的第一象限的2行4列的位图分为4个象限，每个象限为1行2列的位图，第三象限的位图包括数值1，第一象限、第二象限以及和第四象限的位图均为0，则第三象限的位图继续向下展开，第一象限、第二象限以及第四象限的位图停止向下展开。同理，终端设备将第二层的第四象限的2行4列的位图分为4个象限，每个象限为1行2列的位图，第一象限的位图、第二象限以及第四象限的位图均为0，第三象限包括数值1，则第三象限的位图继续向下展开，第一象限、第二象限以及第四象限的位图停止向下展开。
第四层：终端设备将第三层的第三象限的1行2列的位图分为左子树和右子树，每个子树为1行1列的位图，左子树的数值为0，右子树的数值为1。同理，终端设备将第三层的第三象限的1行2列的位图分为左子树和右子树，每个子树为1行1列的位图，左子树的数值为1，右子树的数值为1。
通过四叉树混合二叉树的方式，第一层需要1个比特，第二层需要4个比特，第三层需要8个比特，第四层需要4个比特，则终端设备共需要1+4+8+4＝17个比特传输第一位置数据，而在压缩之前，终端设备共需要4*7＝28比特的传输第一位置数据，故通过四叉树混合二叉树的方式，终端设备可以降低28-17＝11个比特。
在又一种可能的实现方式中，树形数据结构可以为四叉树和四叉树混合二叉树。终端设备可以先分别使用四叉树和四叉树混合二叉树对第一位置数据进行压缩，然后比较两种方式的压缩率，选择压缩率较高的压缩方式所得到的压缩后的第一位置数据。
这种方式，有利于保证更好的压缩率，可以使用不同的场景，应用更加广泛。
在另一种可能的实现方式中，树形数据结构可以为八叉树。第二数据集可以是多个波束的采样数据，该多个波束可以分别对应三维空间中的三个维度，终端设备可以将该三个维度的数据构建立方体，终端设备根据上述方法200确定第一目标数据和第一位数据后，可以根据八叉树对第一位置数据进行压缩，得到压缩后的第一位置数据。
需要说明的是，终端设备还可以使用更高阶的树形数据结构对第一位置进行压缩，此处不再一一赘述。
作为一个可选的实施例，第一信号中可以携带压缩后的第一目标数据和第一位置数据。
第一目标数据可以包括一个或者多个优先级的数据。当第一目标数据包括一个优先级的数据时，终端设备可以将第一目标数据进行压缩，得到压缩后的第一目标数据，然后传输压缩后的第一目标数据。
当第一目标数据包括多个优先级的数据时，终端设备可以将该多个优先级中的部分优先级的数据进行压缩，其他数据可以不压缩，以降低数据的失真度。
示例性地，第一目标数据可以包括5个优先级的数据，分别为第一优先级的数据、第二优先级的数据、第三优先级的数据、第四优先级的数据以及第五优先级的数据，终端设备可以将第一优先级的数据、第二优先级的数据以及第五优先级的数据进行压缩，第三优先级的数据和第四优先级的数据不进行压缩。
当存在两个以及两个以上优先级的数据进行压缩时，可能存在不同的优先级的数 据使用不同的压缩方式，也可能存在不同的优先级的数据使用相同的压缩方式，本申请实施例对此不作限定。其中，压缩方式可以是量化或者熵编码，量化可以是标量量化、矢量量化或者差分量化等，本申请实施例并不限于此。
当存在不同的优先级的数据使用相同的压缩方式时，该不同的优先级的数据可以复用相同的压缩参数，例如，不同的优先级的数据可以使用相同的压缩精度。
当存在不同的优先级的数据使用不同的压缩方式时，不同的压缩方式可以使用不同的压缩参数，例如，优先级级别高的数据使用较高的压缩精度，优先级级别低的数据使用较低的压缩精度。
本申请实施例提供的数据传输方法，将第一目标数据进行压缩后再发送，可以减少传输的数据量，降低传输所使用的资源。
作为一个可选的实施例，上述第一位置数据包括第一目标数据在第二数据集中所处区域的边界信息。
当第一位置数据在第二数据集中的位置呈现聚集性的特点时，终端设备可以将第一目标数据在第二数据集中所处区域的边界信息确定为第一位置数据。应理解，第一位置数据在第二数据集中的位置呈现聚集性的特点，即第一位置数据在第二数据集中的位置比较集中，可以聚集在一个或者多个区域。
第二数据集包括多个波束的采样数据时，若第二数据集中每个波束的采样数据均具有聚集性，且不同的波束的位置数据的聚集性不同，终端设备可以使用一维区间框出每个波束的位置数据所在的区域。若第二数据集中每个波束的采样数据均具有聚集性，且不同的波束的位置数据的聚集性相同，则终端设备可以使用二维区域框出多个波束的位置数据所在的区域。终端设备可以将一维区间或者二维区域的边界对应的位置信息确定为第一位置数据。
示例性地，图9示出了一个波束的采样数据的示意图。波束的采样数据可以是时域数据，图表的横坐标表示采样点的序号，纵坐标表示采样点的幅值，终端设备可以通过两种方式确定第一目标数据。
第一种方式是设置功率阈值delta，将大于delta的采样点确定为第一目标数据。第二种方式是保留预设个数的功率最强的采样点，将该预设个数的采样点确定为第一目标数据。其中，预设个数可以是K。
如图9所示，幅值越高，说明功率越高，保留预设个数的功率最强的采样点，即保留了较强的传输路径的采样点。
通过这两种实现方式，终端设备均可以确定采样点所处的一个一维区间，即感兴趣区域(region of interest，ROI)，终端设备可以保留该区域采样点的最前采样位置t_1和最后采样位置t_2，确定第一目标数据所处的区域为[t_1,t_2]，终端设备可以将最前采样位置t_1和最后采样位置t_2确定为第一位置数据，以降低传输的信息比特。
需要说明的是，若第二数据集为频域的数据集，终端设备可以将第一目标数据所处区域的最小采样位置和最大采样位置确定为第一位置数据。若第二数据集为空域的数据集，终端设备可以将第一目标数据所处区域的水平方向的最小采样位置和垂直方向的最大采样位置确定为第一位置数据。
在电磁成像场景中，第一目标数据大多是目标物体对应的数据，第一位置数据可 以是目标物体所在的区域的边界信息。
示例性地，在上述图4所示的示例中，第一目标数据为目标物体对应的数据，终端设备可以根据第一目标数据的聚集特点，确定一个二维区域，该二维区域包括第一目标数据，该二位区间可以是长方形或者正方形，本申请实施例对此不作限定。终端设备可以将该二维区域的左上角的采样位置和右下角的采样位置确定为第一位置数据。
可选地，上述区域的边界信息可以包括多个区域的边界信息。当第一目标数据所述多个区域时，终端设备可以按照上述方法分别确定该多个区域的边界信息，然后将该多个区域的边界信息确定为第一位置数据。
本申请实施例提供的数据传输方法，通过第一目标区域所处区域的边界信息确定为第一位置数据，通过比较少的信息比特表示第一目标区域在第二数据集中的位置信息，可以降低传输的数据量，节省传输资源。
作为一个可选的实施例，上述第一信号中还携带第二数据集的目标数值，目标数值包括总功率、总能量、平均功率、平均能量、功率方差、或者能量方差中的至少一个。
第二数据集可以包括一个或者多个波束的采样数据。当第二数据集包括一个波束的采样数据时，终端设备计算该波束的所有采样数据的目标数值，即总功率、总能量、平均功率、平均能量、功率方差、或者能量方差中的至少一个。当第二数据集包括多个波束的采样数据时，终端设备可以计算该多个波束中每个波束的所有采样数据的目标数值，即总功率、总能量、平均功率、平均能量、功率方差、或者能量方差中的至少一个。
示例性地，第二数据集以256行1036列的矩阵表示，终端设备需要计算每一行中1036个数据的总功率、总能量、平均功率、平均能量、功率方差、或者能量方差中的至少一个，共得到256个目标数值。
第二数据集中舍弃了低于第一预设门限的数据，造成了部分数据丢失，可能会造成第一目标数据的可信度降低，终端设备计算第二数据集的目标数值通过第一信号进行传输，可以提高第一目标数据的可信度。
本申请实施例提供的数据传输方法，通过目标数值提高第一目标数据和第一位置信息的可信度，可以使第二数据集达到有限压缩的同时，还能在接收端达到较好的环境重构效果。
上面详细介绍了第一信号所承载的数据，下面将详细介绍数据的传输。
在上述S202、终端设备发送第一信号之前，上述方法200还可以包括：网络设备发送第一资源指示信息，第一资源指示信息用于指示第一时频资源，对应地，终端设备接收第一资源指示信息；S202、终端设备发送第一信号，包括：终端设备可以在第一时频资源上发送第一信号，对应地，网络设备在第一时频资源上获取第一信号。
第一时频资源用于承载第一信号，终端设备可以在第一时频资源上发送第一信号。
第一时频资源所承载的数据量可以小于第二目标数据(其中包括第一目标数据)的数据量与第二位置数据(其中包括第一位置数据)的数据量之和，也可以是等于第一目标数据的数据量与第一位置数据的数据量之和，还可以是大于第一目标数据的数据量与第一位置数据的数据量之和，本申请实施例对此不作限定。
可选地，第一信号中所承载的第一目标数据和第一位置信息存在压缩时，终端设备还可以将压缩方式和压缩所使用的参数一起传输。若存在多种压缩方式相同，相同的压缩方式和压缩所使用的相同的参数可以只传输一次。
在一种可能的实现方式中，第一时频资源所承载的数据量等于第一目标数据的数据量与第一位置数据的数据量之和，终端设备在第一时频资源上发送第一信号，第一信号包括第一目标数据和第一位置数据。
在另一种可能的实现方式中，第一时频资源所承载的数据量小于第二目标数据的数据量与第二位置数据的数据量之和，第二目标数据为所有包括第二数据集中优先级大于或等于第一预设门限的数据，第二位置数据包括第二目标数据在第二数据集中的位置信息，第一目标数据和第一位置数据是根据优先级的高低顺序和第一时频资源确定的，第二目标数据包括第一目标数据，第二位置数据包括第一位置数据。
当第一时频资源所承载的数据量小于第二目标数据的数据量与第二位置数据的数据量之和时，第一时频资源不能承载所有的第二目标数据和第二位置数据，但可以承载部分目标数据和部分位置数据。终端设备可以根据优先级的高低顺序和第一时频资源确定第一目标数据和第一位置数据，即可以先发送优先级级别高的数据，且这些数据的数据量等于第一时频资源所承载的数据量。第一目标数据的优先级在第二目标数据中的优先级较高，且第一目标数据的数据量与第一位置数据的数据量之和小于或等于第一时频资源所承载的数据量。
需要说明的是，有些场景下，第一目标数据的数据量与第一位置数据的数据量之和虽小于第一时频资源所承载的数据量，但可能不足以承载其他优先级的数据，此时可以对第一目标数据和第一位置数据补零，以使其等于第一时频资源所承载的数据量。
若第一目标数据包括多个优先级的数据，第二目标数据可以是第一目标数据中的优先级较高的数据，若第一目标数据和第一位置数据包括一个优先级，第二目标数据可以是该优先级中的部分数据。
示例性地，在上述图3所示的示例中，若第二目标数据包括第一优先级的数据和第二优先级的数据，第一目标数据可以是第一优先级的数据。若第二目标数据包括第一优先级的数据，则第一目标数据是第一优先级的部分数据。
本申请实施例提供的数据传输方法，通过第一时频资源的数据量确定传输的数据，增加了数据传输的灵活性。
终端设备传输第一目标数据和第一位置数据之外，是否还需要继续传输，可以由终端设备确定，也可以由网络设备确定，本申请实施例对此不作限定。
可选地，终端设备传输第一目标数据和第一位置数据之外，终端设备可以确定是否继续传输数据。
终端设备在第一时频资源上发送第一信号之后，上述方法还可以包括：终端设备发送第一指示信息，第一指示信息用于指示数据传输未完成，对应地，网络设备接收第一指示信息。或者，终端设备发送第二指示信息，第二指示信息用于指示数据传输完成，对应地，网络设备接收第二指示信息。
第一目标数据中除第一目标数据之外的目标数据，第二位置数据中除第一位置数据之外的位置数据，是否需要继续传输，可以由终端设备确定。若第一目标数据和第 一位置信息未达到压缩精度的要求，终端设备可以确定继续传输数据，并向网络设备发送第一指示信息，第一指示信息用于指示数据传输未完成。若第二目标数据和第二位置信息已经达到了压缩精度的要求，终端设备可以确定不再继续传输数据，并向网络设备发送第二指示信息，该第二指示信息用于指示数据传输完成。
示例性地，图10示出了一种数据传输方法1000的示意性流程图。如图10所示，该方法1000可以包括如下步骤：
S1001、网络设备向终端设备发送第一资源指示信息，对应地，终端设备接收第一资源指示信息，第一资源指示信息用于指示第一时频资源，第一时频资源所承载的数据量小于第二目标数据的数据量与第二位置数据的数据量之和。
S1002、终端设备在第一时频资源上向网络设备发送第一信号，第一信号中携带第一目标数据和第一位置数据，对应地，网络设备在第一时频资源上接收第一信号。
S1003、终端设备向网络设备发送第一指示信息，第一指示信息用于指示数据传输未完成，对应地，网络设备接收该第一指示信息。
本申请实施例提供的数据传输方法，当第一时频资源所承载的数据量小于第二目标数据的数据量与第二位置数据的数据量之和时，可以在第一时频资源传输部分目标数据和部分位置数据，终端设备可以自主确定是否继续传输数据，增加了终端设备的能动性。
可选地，若终端设备发送第一指示信息，网络设备接收第一指示信息后，可以再次发送时频资源，终端设备可以利用该时频资源传输剩余的数据，具体传输的数据量可以由时频资源所承载的数据量决定。若仍未传输完成，终端设备还可以继续发送第一指示信息，继续利用网络设备发送的时频资源传输数据，直至达到要求或者将第一目标数据和第一位置数据传输完成。
可选地，终端设备传输第一目标数据和第一位置数据之外，网络设备可以确定是否继续传输数据。
终端设备在第一时频资源上发送第一信号之后，上述方法还可以包括：网络设备向终端设备发送时频资源；对应地，终端设备接收该时频资源，并在时频资源上发送剩余的数据，具体传输的数据量可以由时频资源所承载的数据量决定。若仍未传输完成，网络设备还可以继续发送时频资源，终端设备可以继续利用网络设备发送的时频资源传输数据，直至达到要求或者将第二目标数据和第二位置数据传输完成。
本申请实施例提供的数据传输方法，当第一时频资源所承载的数据量小于第二目标数据的数据量与第二位置数据的数据量之和时，可以在第一时频资源传输部分目标数据和部分位置数据，网络设备确定是否继续传输数据，可以降低对终端设备要求。
在又一种可能的实现方式中，当第一时频资源所承载的数据量大于第一目标数据的数据量与第一位置数据的数据量之和时，上述方法还可以包括：终端设备在第一时频资源上发送第三信号，第三信号中携带第三目标数据和第三位置数据，第三目标数据包括第二数据集中优先级小于第一预设门限，且大于或等于第二预设门限的数据，第三位置数据包括第三目标数据在第二数据集中的位置信息，第二预设门限小于第一预设门限。
当第一时频资源所承载的数据量大于第一目标数据的数据量与第一位置数据的数 据量之和时，第一时频资源除承载第一目标数据和第一位置信息外，还可以承载额外的数据。此时，终端设备可以传输低于第一预设门限的数据。第二预设门限可以根据第一时频资源所承载的数据量确定。第三目标数据为优先级低于第一预设门限，但大于或等于第二预设门限的数据，第三位置数据包括第三目标数据在第二数据集中的位置信息。第三目标数据的数据量、第三位置数据的数据量、第一目标数据的数据量以及第一位置数据的数据量之和小于或等于第一时频资源所承载的数据量。
