为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、通信感知一体化(Integrated Sensing And Communication，ISAC)。
通信感知一体化也可称之为通感一体化，以未来超第5代移动通信(Beyond Fifth Generation，B5G)和6G无线通信系统有望提供各种高精度的传感服务，如机器人导航的室内定位、智能家居的Wi-Fi传感和自动驾驶汽车的雷达传感。传感和通信系统通常是单 独设计的，并占用不同的频段。ISAC能够使得传感和通信系统共享同一频段和硬件、提高频率效率并降低硬件成本。ISAC将成为未来无线通信系统的一项关键技术，以支持许多重要的应用场景。ISAC的典型应用包括：自动驾驶车辆的导航和避障、基于Wi-Fi的室内定位和活动识别、无人驾驶飞机的通信和传感、扩展现实(Extended Reality，XR)、雷达和通信一体化等。每个应用都有不同的要求、限制和监管问题。
ISAC通过硬件设备共用和软件定义功能的方式获得通信和感知双功能的一体化低成本实现，特点主要有：一是架构统一且简化，二是功能可重构可扩展，三是效率提升、成本降低。通信感知一体化的优势主要有三个方面：一是设备成本降低、尺寸减小，二是频谱利用率提升，三是系统性能提升。
目前，根据5G通信系统架构进行技术升级而有望实现的典型通信感知一体化的场景如下表一所示。
表一：
二、通信和通感一体化中的资源开销。
在通信系统中，特别是在多输入多输出(Multiple-Input Multiple-Output，MIMO)场景下，每个端口都需要配置对应的参考信号；随着端口数越来越大，参考信号的时频资源开销也越来越大。如图2所示，为32端口的信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)配置的一个示例，CSI-RS的时频资源开销已经较大。而随着通信系统的演进，在大规模MIMO(massive MIMO，mMIMO)和超大规模MIMO(extremely large-scale MIMO，el-MIMO)场景下，CSI-RS所需的时频资源开销将进一步加大，造成MIMO系统增益的下降。因此，在满足信道测量的前提下，如何尽可能地减小参考信号的时频资源开销，是一个非常重要的问题。
另外，在通感一体化的感知业务中，为了实现距离、速度和角度等的高性能感知，感 知信号的资源开销较大。首先，距离感知的分辨率取决于感知信号的带宽，因此通常感知信号带宽需要在百MHz量级及以上；其次，速度感知的分辨率取决于感知信号的时长，因此通常感知信号时长需要在十ms量级及以上；最后，角度感知的分辨率取决于天线孔径，为了实现高分辨率的测角，需要配置较大的天线孔径。
如果感知信号在所需的带宽、时长和天线孔径内按照传统方法的均匀分布，则感知信号的时、频、空域的资源开销会比较大。因此，在满足感知需求的前提下，如何尽可能地减小感知信号的时、频、空域资源开销，也是通感一体化中的重要议题。
三、压缩感知(Compressed sensing)。
压缩感知也被称为压缩采样(Compressive sampling)或稀疏采样(Sparse sampling)。它作为一个新的采样理论，它通过开发信号的稀疏特性，在小于奈奎斯特采样率的条件下，用随机采样获取信号的离散样本，然后通过非线性重建算法重建信号。因此，压缩采样能够降低数据的采样速率，从而能够降低数据量和对高速采样的要求等。
假设x表示长度为N的一维信号，也就是原信号，其在变换域的信号s为K稀疏信号，即s中有显著值的样值点个数不大于K；Ψ为稀疏矩阵，将信号s变换为x；Φ为观测矩阵，对应着亚采样这一过程，将高维信号x投影到低位空间得到亚采样之后的信号y＝ΦΨs。通常将Ψ和Φ合并成一个矩阵，表示为Θ＝ΦΨ，称为传感矩阵。
亚采样之后的信号y的长度为M，且有M<N。在传统的奈奎斯特采样下，输出信号为x；而在压缩采样下，输出信号为y；由于M<N，因此采样率降低了。
将压缩感知与通感一体化结合起来，则x、y和s有如下情况至少之一：
x和y为频率维信号、s为时延维信号；
x和y为慢时间维信号、s为多普勒维信号；
x和y为天线阵列水平方向各天线单元或天线端口的信号、s为方位向角度维信号；
x和y为天线阵列数值方向各天线单元或天线端口的信号、s为俯仰向角度维信号。
为了能够通过压缩后的信号y重建压缩之前的信号x或s，有如下两个条件：
稀疏性：x或者x的变换域信号s具有稀疏性，即具有显著值的样值点数不大于K；
不相关性：观测矩阵Φ的基(矩阵的列)和稀疏矩阵Ψ的基(矩阵的列)之间不相关。
在通信信道或者通感一体化的感知信道中，稀疏性条件通常是满足的。满足不相关性的典型的观测矩阵和稀疏矩阵有：
观测矩阵：随机高斯矩阵、随机伯努利矩阵、部分正交矩阵、随机稀疏矩阵，拓普利兹和循环矩阵、轮换矩阵、哈达玛矩阵；
稀疏矩阵：离散傅里叶变换矩阵、离散预先变换矩阵、小波变换矩阵等。
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信号配置自适应处理方法进行详细地说明。

为例更好的理解本申请，以下通过一些具体实例进行详细说明。
在一些实施例中，可以根据第一指标和第二指标确定目标信息值。
本实施例中，所述第一指标(例如，也可以被称为稀疏因子)的数值越小表示信号在时延域、多普勒域和角度域中的至少一项越稀疏，即信号在时延域、多普勒域和角度域中的至少一项大于所述第一预设门限的样值点越少；第二指标的数值越大表示信号质量越好。
如图4所示，在本实施例中，有如下设定：
将第一指标的可能取值范围划分为若干个区间(图中所示为7个区间，从小到大依次表示为S1,S2,…,S7)；
将第二指标的可能取值范围划分为若干个区间(图中所示为7个区间，从小到大依次表示为P1,P2,…,P7)；
目标信息值用于指示目标信号在时间域、频率域、空间域所占用的资源数量，可以取若干个预先设定的值(图中所示为可取7个值，从小到大依次表示为M1,M2,…,M7)
根据上述设定，从第一指标和第二指标到目标值之间的映射关系有如下原则：
第二指标取最小值时(即，信号质量很差)，无论第一指标取何值，目标信息值只能取 最大值；
第一指标取最大值时(即，信号稀疏程度低)，无论第二指标取何值，目标信息值只能取最大值；
在前两条的约束下，给定第二指标的取值，第一指标的取值越大时，目标信息值的取值越大；
在前两条的约束下，给定第一指标的取值，第二指标的取值越大时，目标信息值的取值越小。
根据上述原则，在确定了第一指标和第二指标之后，即可通过查表的方式确定目标信息值。
基于图4表示的第一指标和第二指标到目标信息值之间的映射关系，也可以由映射函数的形式来表示，在此不再赘述。
在一些实施例中，可以根据第一指标确定目标信息值。
在本实施例中，目标信息值值仅由第一指标(例如，也可以被称为稀疏因子)确定。
如图5所示，在本实施例中，有如下设定：
将第一指标的可能取值范围划分为若干个区间(图中所示为7个区间，从小到大依次表示为S1,S2,…,S7)；
目标信息值用于指示目标信号在时间域、频率域、空间域所占用的资源数量，可以取若干个预先设定的值(图中所示为可取7个值，从小到大依次表示为M1,M2,…,M7)；
第一指标的取值越大时，目标信息值的取值越大。
基于图5表示的第一指标到目标信息值之间的映射关系，也可以由映射函数的形式来表示，在此不再赘述。
可选地，在一些实施例中，可以通过资源网格和目标资源图样确定目标信号的资源配置。其中，该资源配置包括时间域资源配置、频率域资源配置和空间域资源配置。
其中，时间域资源配置主要应用于通感一体化中需要测量多普勒(或速度)的场景，在时间域上配置一组OFDM符号构成一个感知帧，用于执行一次多普勒(或速度)的测量，满足：感知帧的时间跨度满足多普勒测量分辨率要求、感知帧内OFDM符号之间的时间间隔满足多普勒的最大不模糊测量范围要求。
如图6所示，这里以NR中CSI-RS的配置为例进行说明。用来确定时间域资源网格的CSI-RS的配置参数包括：firstOFDMSymbolInTimeDomain＝6、CSI-ResourcePeriodicityAndOffset->slots4＝0。由这些参数确定了每4个slot中的第0个slot中的第6个(从0开始计数)OFDM符号为分配给所述资源网格的OFDM符号。图中所述的资源网格长度为48，可以由MAC控制元素(MAC Control Element，MAC CE)的激活和去激活半持续的CSI-RS资源来控制感知帧的时间跨度、进而确定资源网格长度，或者，在后续为通感一体化功能新增关于感知帧的时间跨度参数。
在确定目标信号在时间域上所在的资源网格之后，在本示例中以随机伯努利函数生成 所述的目标图样序列。随机伯努利函数的随机数种子取值为seed＝1，随机伯努利试验中出现‘1’的概率为0.4，生成的目标图样序列如图6所示。在与目标图样序列中‘1’对应的资源网格中的OFDM符号(资源网格n和资源网格n+2)为分配给目标信号的OFDM符号，在与目标图样序列中‘0’对应的资源网格中的OFDM符号(资源网格n+1)为未分配给目标信号的OFDM符号(即，节约的OFDM符号)。在本实施例中，随机伯努利试验中出现‘1’的概率或者随机数种子，可以作为目标信息值由第一设备向第二设备上报。
如图7所示，这里以NR中的CSI-RS的配置为例进行说明。用来确定频率域资源网格的CSI-RS的配置参数包括：startingRB(图中未标出)、nrofRB＝48、frequencyDomainAllocation->row2＝’0000001000000’、density＝1。由这些参数确定了在指定的连续48个RB内每个RB中的第6个(从0开始计数)子载波为分配给所述资源网格的子载波。
在确定目标信号在频率域上所在的资源网格之后，在本示例中以随机伯努利函数生成所述的目标图样序列。随机伯努利函数的随机数种子取值为seed＝1，随机伯努利试验中出现‘1’的概率为0.4，生成的目标图样序列如图7所示。在与目标图样序列中‘1’对应的资源网格中的子载波(图中资源网格n+1、资源网格n+2和资源网格n+5)为分配给目标信号的子载波，在与目标图样序列中‘0’对应的资源网格中的子载波(图中资源网格n、资源网格n+3、资源网格n+4和资源网格n+6)为未分配给目标信号的子载波(即，节约的子载波)。在本实施例中，随机伯努利试验中出现‘1’的概率或者随机数种子，可以作为目标信息值由第一设备向第二设备上报。
如图8所示，这里以天线面板的水平方向或者数值方向中的一个维度为例进行说明，在该维度上由连续的48个天线端口或者天线单元构成所述的资源网格。
在确定目标信号在空间域上所在的资源网格之后，在本示例中以随机伯努利函数生成所述的目标图样序列。随机伯努利函数的随机数种子取值为seed＝1，随机伯努利试验中出现‘1’的概率为0.4，生成的目标图样序列如图8所示。在与目标图样序列中‘1’对应的资源网格为分配给目标信号的天线端口或天线单元，在与目标图样序列中‘0’对应的资源网格中为未分配给目标信号的天线端口或天线单元(即，节约的天线端口或天线单元)。在本实施例中，随机伯努利试验中出现‘1’的概率或者随机数种子，可以作为目标信息值由第一设备向第二设备上报。
可选地，在一些实施例中第一设备可以根据目标指标确定目标信息值，并向第二设备上报目标信息值，进而第二设备根据目标信息值进行目标信号的资源配置的链路自适应调节，其中，目标指标包括第一指标或者包括第一指标和第二指标。
一实施例中，如图9所示，可以包括以下流程：
步骤901，第二设备向第一设备发送第一配置信息和第二配置信息中至少一项的至少部分信息；
步骤902，第一设备确定目标指标，并根据目标指标确定目标信息值；
步骤903，第一设备向第二设备发送目标信息值；
步骤904，第二设备判断并执行链路自适应调节；
步骤905，第二设备向第一设备发送第三配置信息。
一实施例中，如图10所示，可以包括以下流程：
步骤1001，第二设备向第一设备发送第一配置信息和第二配置信息中至少一项的至少部分信息；
步骤1002，第一设备确定目标指标；
步骤1003，第一设备向第二设备发送目标指标；
步骤1004，第二设备确定目标信息值，判断并执行链路自适应调节；
步骤1005，第二设备向第一设备发送第三配置信息。
针对图9和图10，上述第一设备和第二设备可以包括以下任一项：
情况1，第一设备为终端，第二设备为接入网设备或核心网设备(如感知功能网元)；
情况2，第一设备为终端1，第二设备为终端2；
情况3，第一设备为接入网设备，第二设备为核心网设备；
情况4，第一设备为接入网设备1，第二设备为接入网设备2。
可选地，上述各情况中部分情况(如情况1)适用于通信场景，所有的情况都适用于通感场景。
可选地，在一些实施例中，在频率域进行自适应调节。
信道在时延域具有稀疏性，利用信道在时延域的稀疏性，可以根据本申请的信号配置自适应处理方法在频率域对目标信号进行稀疏配置，以节约目标信号的频域资源开销。所述目标信号可以是：通信中的参考信号、或者通感一体化中的感知信号。其基本思想是：根据信道测量的结果，从配置的频域资源中链路自适应地选择一部分子载波用于目标信号的配置、而未被选择的子载波则被节约下来。其中，配置的频域资源可以理解为上述资源网格或者资源网格的一部分。
第一设备通过对目标信号进行测量，得到目标指标，目标指标包括第一指标，或者包括第一指标和第二指标；其中，第一指标可以是时延域中超过第一预设门限的样值点数、或者第一指标是与时延域中超过第一预设门限样值点数相关的其他指标。例如，可以将时延域超过第一预设门限样值点数的取值范围划分为若干个区间，每个区间对应一个ID，实际测得的时延域超过第一预设门限样值点数落入哪个区间，则第一指标为该区间对应的ID。
在一些实施方式中，第一设备通过信令向第二设备反馈目标指标，由第二设备基于算法确定所述目标信息值，进而确定目标图样序列，并将所述目标图样序列通知给第一设备(即，所述的第三配置信息)。之后，配置的频域资源(即，所述的资源网格)中对应于目标图样序列为‘1’的子载波仍然发送目标信号、而配置的频域资源(即，所述的资源网格)中对应于目标图样序列为‘0’的子载波则不发送目标信号。
在另一些实施方式中，第一设备根据目标指标确定所述目标信息值，进而确定目标图 样序列。在此之前，第二设备需要将确定目标信息值和目标图样序列的方法配置给第一设备(即，所述的第二配置信息)。第一设备确定目标信息值之后，通过信令向第二设备反馈该目标信息值。由于目标信息值与目标图样序列唯一对应，第二设备获得目标信息值后即可获取第一设备推荐的目标图样序列。第二设备可以选择采用该目标信息值对应的目标图样序列、也可以不采用该目标信息值对应的目标图样序列。如果第二设备采用了该目标图样序列，则配置的频域资源(即，所述的资源网格)中对应目标图样序列为‘1’的子载波仍然发送目标信号、而配置的频域资源(即，所述的资源网格)中对应目标图样序列为‘0’的子载波则不发送目标信号。第二设备可以通过一个简单的确认信息(即，所述的第三配置信息)向第一设备指示第二设备是否采用了推荐的目标图样序列，例如：该确认信息可以是一个1比特的信息。第一设备在收到该确认信息后即可知道第二设备是否采用该目标图样序列。如果第二设备采用了该目标图样序列，则第一设备根据目标图样序列确定的目标信号的频域资源配置进行目标信号的接收，否则第一设备根据之前的配置进行目标信号的接收。
如图11所示，为采用本申请的方案进行目标信号的稀疏配置的示意图，以32端口CSI-RS为例。在根据目标图样序列进行目标信号的频域资源的链路自适应调节之后，配置的频域资源(即，所述的资源网格)中，对应右侧目标图样序列中为‘1’的资源网格中的子载波仍有CSI-RS发送(如下图中各种不同图案填充的部分)，而对应右侧目标图样序列中为‘0’的资源网格中的子载波则没有CSI-RS发送(如下图中灰色填充的部分)。
可选地，在一些实施例中，在时间域进行自适应调节。
信道在多普勒域具有稀疏性，利用信道在多普勒域的稀疏性，可以根据本申请的信号配置自适应处理方法在时间域对目标信号进行稀疏配置，以节约目标信号的时域资源开销。所述目标信号可以是：通信中的参考信号、或者通感一体化中的感知信号。实际上，只有与目标信号的收发端设备之间有相对运动的散射体才会在目标信号上产生多普勒频移；因此，通常信道在多普勒域的稀疏程度较高。其基本思想是：根据信道测量的结果，从配置的时域资源中链路自适应地选择一部分OFDM符号用于目标信号的配置、而未被选择的OFDM符号则被节约下来。其中，配置的频域资源可以理解为上述资源网格或者资源网格的一部分。
第一设备通过对目标信号进行测量，得到目标指标，目标指标包括第一指标，或者包括第一指标和第二指标；其中，第一指标可以是多普勒域中超过第一预设门限的样值点数、或者第一指标是与时延域中超过第一预设门限样值点数相关的其他指标。例如，可以将时延域超过第一预设门限样值点数的取值范围划分为若干个区间，每个区间对应一个ID，实际测得的时延域超过第一预设门限样值点数落入哪个区间，则第一指标为该区间对应的ID。
自适应调节的流程如图11所示的实施例类似，在此不再赘述。
如图12所示，为采用本申请的方案进行目标信号的稀疏配置的示意图，本实施例中与图11所示的实例的区别在于本实施例是应用在时间域，与应用在频率域类似，在此不 再赘述。应理解，在图12中目标信号的时域周期为1个时隙是为了方便制图。
可选地，在一些实施例中，在空间域进行自适应调节。
信道在角度域的稀疏性，特别是在端口数较大的MIMO场景(例如：mMIMO、el-MIMO)下，可以根据本申请的信号配置自适应处理方法通过一部分端口的参考信号传输即可完成信道估计，而不必要每个端口都有目标信号的传输，从而也能够节约时频资源的开销和天线端口的开销中的至少一项。所述目标信号可以是：通信中的参考信号、或者通感一体化中的感知信号。其基本思想是：根据信道测量的结果，从配置的空间域资源(天线端口)中链路自适应地选择一部分天线端口用于目标信号的配置、而未被选择的天线端口则被节约下来。其中，根据相关技术方法配置的空间域资源，即是技术方案部分所述的资源网格。由于有部分天线端口无需发送目标信号，因此目标信号所占用的时频域资源开销相应地减小了。另外，在通感一体化应用中，不发送感知信号的端口可以被关闭或者用作其他业务。
第一设备通过对目标信号进行测量，得到目标指标，目标指标包括第一指标，或者包括第一指标和第二指标；其中，第一指标可以是角度域中超过第一预设门限的样值点数、或者第一指标是与时延域中超过第一预设门限样值点数相关的其他指标。例如，可以将时延域超过第一预设门限样值点数的取值范围划分为若干个区间，每个区间对应一个ID，实际测得的时延域超过第一预设门限样值点数落入哪个区间，则第一指标为该区间对应的ID。
自适应调节的流程如图11所示的实施例类似，在此不再赘述。
如图13所示，为采用本申请的方案进行目标信号的稀疏配置的示意图，仍以32端口CSI-RS为例。对应目标图样序列中为‘1’的端口中仍有CSI-RS发送，而对应目标图样序列中为‘0’的端口中则没有CSI-RS发送。在采用本申请的方案之前，分配给CSI-RS的32个端口构成4个码分复用(Code Division Multiplexing，CDM)组(group)，每个CDM group包含8个端口。在某一次链路自适应过程中，根据信道测量结果，仅需要16个端口即可实现整个角度域的信道估计，该16个端口由目标图样序列在原先的32个端口中确定。例如，之前的4个CDM group中分别有6个、3个、3个、4个端口由目标图样序列选择出来，构成2个新的CDM group，即图中的CDM group5和CDM group6。而CDM group5和CDM group6在时频域上占用了原先CDM group1和CDM group2的资源，从而原先CDM group3和CDM group4的时频资源(下图中灰色填充部分)则被节约了下来。
参照图14，本申请实施例还提供了一种信号配置自适应处理方法，如图14所示，该信号配置自适应处理方法包括：
