  • Wireless communication and radar sensing have been developing in parallel, but with limited overlap. They have a lot in common in terms of signal processing algorithms, equipment, and to some extent, system architecture. In recent years, traditional radars are moving towards a more general wireless sensing direction. Wireless sensing can broadly refer to retrieving information from received radio signals. For wireless sensing related to the location of the sensing target, the dynamic parameters such as the target signal reflection delay, arrival angle, departure angle, Doppler, etc. can be estimated through common signal processing methods; for sensing the physical characteristics of the target, it can be achieved by measuring the inherent signal patterns of the device/object/activity. The two sensing methods can be called perception parameter estimation and pattern recognition, respectively. In this sense, wireless sensing refers to more general sensing technologies and applications using radio signals.
  • Integrated Sensing and Communication has the potential to integrate wireless sensing into mobile networks, referred to here as perceptive mobile networks (PMNs), as in reference [1].

It can also provide complementary sensing capabilities to existing sensor networks, with unique day and night operation capabilities and the ability to penetrate fog, foliage, and even solid objects.
  • the range resolution and velocity (radial) resolution of the radar depend on the signal form selected by the radar.
  • the wider the frequency band occupied by the radar signal in the frequency domain the better its range resolution; the larger the continuous width of the radar signal in the time domain, the better its velocity resolution.
  • Designing radar signals from the perspective of improving radar resolution requires that the main peak of the signal ambiguity function is high and sharp, and the secondary peak is low and flat.
  • Commonly used radar signals such as Linear Frequency Modulation (LFM), have coupling between Doppler shift and distance.
  • LFM Linear Frequency Modulation
  • the sidelobe level of the autocorrelation function of the nonlinear frequency modulation signal (Non LFM, NLFM) has improved, but there are still large range sidelobes on the high Doppler frequency section of the ambiguity function.
  • the sidelobes of large targets or clutter will cover the mainlobes of small targets near the sidelobes.
  • the synthesis of the sidelobes of multiple target responses may even cover the mainlobes of stronger target responses.
  • Radar signal design often requires the signal to have a large time-bandwidth product, constant envelope, and good autocorrelation characteristics.

  • n-order Costas array For an n-order Costas array, its number is finite. Costas arrays can be quickly constructed using finite field theory.
  • a "field” is a set (algebraic structure) on which addition, subtraction, multiplication and division operations can be performed without exceeding the result itself. Its concept is the generalization of number fields and arithmetic operations. If the field F contains only a finite number of elements, it is called a "finite field (Galois Field, GF)", also known as a "Galois field”.
  • the sequence P is a (l-1)-order permutation matrix.
  • the sufficient condition for the sequence P to be a Costas sequence is that the placement function of the sequence P is: y(k) ⁇ k (mod l),1 ⁇ k ⁇ l-1, (1)

If any two vectors of P are different, that is, the lengths and directions of the two vectors are different but the same, then the sequence P is a Costas sequence, see reference [3].
  • Costas arrays can also be obtained by exhaustive search, that is, searching for Costas sequences in n! n-order permutation matrices.
  • the search method can adopt the method of calculating the check matrix of the permutation matrix. In order to reduce the computational workload, the properties of the check matrix can be used to simplify the calculation.

  • Table 2 shows four 17-order Costas arrays, which have a low cross-correlation between any two of them. The total number of 17-order Costas arrays is 18,276. Finding Costas arrays that satisfy the requirement of low cross-correlation between any two of them generally requires searching through optimization algorithms such as genetic algorithms and simulated annealing algorithms.
  • Quadratic/cubic congruential arrays can also be constructed by algebraic methods, and all arrays of a given l-order array can be constructed by algebraic methods, with a total of l-1, where l is required to be an odd prime number.
  • Reference [8] points out that the autocorrelation and cross-correlation characteristics of quadratic congruential arrays are very good, especially the cross-correlation characteristics are better than the Costas array, but the autocorrelation characteristics are slightly worse than the Costas array.
  • Reference [9] points out that the autocorrelation and cross-correlation characteristics of cubic congruential arrays are relatively balanced, and the auto-ambiguity function (Auto-Ambiguity Function) and cross-ambiguity function (Cross-Ambiguity Function) of the array have at most 2 and 3 coincidence points (Coincidence). From references [9] and [10], it can be seen that the placement function of the quadratic/cubic congruential array is: y(k) ⁇ (k-1) ⁇ (mod l),1 ⁇ k ⁇ l, (6) Where l is an odd prime number and is also the order of the quadratic/cubic congruential array, and ⁇ is a positive integer.

1、通信感知一体化/通感一体化
无线通信和雷达传感(Communication&Sensing,C&S)一直在并行发展，但交集有限。它们在信号处理算法、设备以及一定程度上的系统架构方面都有很多共性。近年来，传统雷达正朝着更通用的无线感知方向发展。无线感知可广泛地指从接收到的无线电信号中检索信息。对于感知目标位置相关的无线感知，可以通过常用的信号处理方法，对目标信号反射时延、到达角、离开角、多普勒等动力学参数进行估计；对于感知目标物理特征，可以通过对设备/对象/活动的固有信号模式进行测量来实现。两种感知方式可以分别称为感知参数估计以及模式识别。在这个意义上，无线感知是指使用无线电信号的更通用的传感技术和应用。
通信感知一体化(Integrated Sensing and Communication，ISAC)有潜力将无线感知集成到移动网络中，这里称之为感知移动网络(Perceptive Mobile Networks，PMNs)，如参考文献[1]。感知移动网络能够同时提供通信和无线感知服务，并且由于其较大的宽带覆盖范围和强大的基础设施，有望成为一种无处不在的无线传感解决方案。感知移动网络可以广泛应用于交通、通信、能源、精准农业和安全领域的通信和传感。它还可以为现有的传感器网络提供互补的传感能力，具有独特的昼夜操作功能，能够穿透雾、树叶甚至固体物体。一些常见的感知业务如下表1所示。
表1常见感知业务分类

2、雷达信号设计与信号处理
雷达的距离分辨率和速度(径向)分辨率取决于雷达选择的信号形式，雷达信号在频域上占据的频带越宽，则其距离分辨率越好；雷达信号在时域上持续宽度越大,则其速度分辨率越佳。从提高雷达分辨率的角度设计雷达信号，就要求信号模糊函数的主峰高而尖锐，副峰低而平坦。常用的雷达信号，例如线性调频信号(Linear Frequency Modulation，LFM)存在多普勒频移与距离的耦合，当目标回波的多普勒频移较大时将产生较大的测距误差；非线性调频信号(Non LFM，NLFM)自相关函数的旁瓣电平有所改善，但在模糊函数高多普勒频率截面上仍存在较大的距离旁瓣，大目标或杂波的旁瓣将掩盖旁瓣附近小目标的主瓣，在多目标环境中，多个目标响应旁瓣的合成，甚至可能掩盖较强目标响应的主瓣。
感知/通感一体化信号设计是通感一体化技术研究的重点，其设计思路可以借鉴雷达信号设计。雷达信号设计往往要求信号具有大时宽-带宽积、恒包络、自相关特性好，对于MIMO雷达，还要求各天线端口信号具有良好的正交性。
2.1 Costas阵列
设P为n阶置换矩阵，该阵列(横轴方向)表示时间，行(纵轴方向)表示频率，矩阵元素“1”的行索引序列(跳频信号序列)也称序列P。若序列P的(离散)自相关函数R(τ,d)副瓣的最大值不大于1，则称置换矩阵P为n阶Costas阵列(Costas Array)，称该序列P为Costas序列。一般使用{c1,c2,...,cn}表示序列P。在本申请中，“Costas阵列”与“Costas序列”等价，只是名称不同。Costas序列特殊的序列结构，导致其具有理论最优的模糊函数性能，即模糊函数图形具有“图钉状”特征，见参考文献[2]。
应理解，“阵列”是从时频二维资源格的角度命名的，“序列”是从信号的角度命名的，两者指的是同一个事物。“Costas阵列”等同于“Costas序列”。
对于一个n阶Costas阵列，其数量是有限的。Costas阵列可以通过有限域理论快速构造。在抽象代数中，“域”是一种可在其上进行加、减、乘和除运算而结果不会超自身的集合(代数结构)，其概念是数域以及四则运算的推广。若域F只包含有限个元素，则称其为“有限域(Galois Field，GF)”，又称“伽罗华域”。
(1)Welch-Costas阵列
设有限域GF(l)，l为素数，α为GF(l)的本原元(Primitive Element)，η为GF(l)的非零元(Non-zero Element，即非零元素)，序列P为(l-1)阶置换矩阵，则序列P为Costas序列的充分条件是序列P的放置函数为：
y(k)≡ηαk(mod l),1≤k≤l-1,         (1)
这种阵列称为Welch-Costas阵列。Welch-Costas序列在水平方向是以l-1为循环周期的，在垂直方向以l为循环周期。式(1)表示的序列可以看作由式(2)表示的序列在水平方向进行循环移位得到的，式(2)如下：
y(k)≡αk(mod l),1≤k≤l-1,      (2)
即η取1。通过等式(2)构造的Welch-Costas又称为Exponential Welch-Costas。等式(2)的反函数为定义如下
y(k)≡logαk(mod l-1),0≤k≤l-1,      (3)
可以理解，利用等式(3)也可以构造出Costas阵列，由此得到的Welch-Costas又称为Logarithmic Welch-Costas。
需要说明的是，本原元的概念为：模n下a的阶m＝phi(n)，a就是n的本原元；本原元并不唯一；阶的概念为：有限域中元素的个数称为有限域的“阶”；欧拉函数：phi(x)为欧拉函数，其值为小于n且与n互质的非零正整数的个数；例如：phi(8)＝4(1,3,5,7)；若n为质数，则phi(n)＝n-1；例如：phi(7)＝6(1,2,3,4,5,6)。举例：n＝7，3为有限域GF(7)的本原元，因为：7为质数，所以phi(7)＝7-1＝6；且模7下3的阶＝6；(30mod7＝1,32mod7＝3,32mod7＝2,33mod7＝6,34mod7＝4,35mod7＝5,36mod7＝1,37mod7＝3,…；即循环为6)；本原元并不唯一，例如：GF(19)的本原元有2,3,10；GF(13)的本原元有2,6,7,11。
(2)Golomb-Costas阵列
设有限域GF(q)，其中q＝lm，l为素数，m为正整数。α，β为GF(q)的本原元，序列P为Golomb-Costas序列的充分条件是序列P的放置函数为
y(k)≡logβ(1-αk)(mod f(x)),0≤k≤q-2,      (4)
其中f(x)整数模l的同余类域Zl上的任一个m次不可约多项式，见参考文献[3],[4]。上式也就是：若设序列P的单元格的坐标为(i,j)，则当αi+βj≡1(mod f(x))时，在该单元格放置“1”。这种结构的Costas阵列称为Golomb-Costas阵列。
(3)Lempel-Costas阵列
若取α＝β，则称等式(5)得到的阵列为Lempel-Costas阵列，
y(k)≡logα(1-αk)(mod f(x)),0≤k≤q-2.      (5)
Costas阵列还可以通过几何构造法获得。连接置换序列P的两个“1”单元格的有向线段称为序列P的向量。若P的任两个向量都不相同，即两个向量的长度和方向不同时相同，则序列P为Costas序列，见参考文献[3]。Costas阵列还可以通过穷举法搜索获得，即在n！个n阶置换矩阵中搜索Costas序列，搜索的方法可以采用计算置换矩阵的校验矩阵(Check Matrix)的方法，为了减小计算工作量，可以利用校验矩阵的性质简化计算。
表2 4个具有低互相关性的17阶Costas阵列示例
任意1个n阶Costas阵列具有理想的自相关特性，但是相同阶数的不同Costas阵列之间不一定具有较低的互相关性(对应较好的正交性)。表2给出了4个17阶Costas阵列，它们任意两两之间具有较低的互相关性。17阶Costas阵列的总数为18276个，寻找具有满足任意两两之间具有较低的互相关性Costas阵列一般需要通过遗传算法、模拟退火算法等优化算法搜索得到。
有关Costas阵列的更多性质、更详细介绍可以参考文献[2]-[6]以及其中的参考文献，阶数3-1030的Costas阵列详细信息可以在参考文献[7]中查询得到，在此不做赘述。
2.2二次/三次同余(Quadratic/Cubic Congruence)阵列
二次/三次同余阵列也可以通过代数法构造，且通过代数法能够构造出给定l阶阵列的所有阵列，总共有l-1个，其中l要求为奇质数。参考文献[8]指出，二次同余阵列的自相关和互相关特性都非常优良，尤其是互相关特性要比Costas阵列更好，但自相关特性要比Costas阵列差一些。参考文献[9]指出，三次同余阵列自相关和互相关特性两方面都比较均衡，该阵列的自模糊函数(Auto-Ambiguity Function)和互模糊函数(Cross-Ambiguity Function)最多只有2个和3个重合点(Coincidence)。由参考文献[9]和参考文献[10]可知，二次/三次同余阵列的放置函数为：
y(k)≡γ(k-1)κ(mod l),1≤k≤l,      (6)
其中l为奇质数同时为二次/三次同余阵列的阶数，γ为正整数。κ取值为2或3，分别对应二次同余阵列和三次同余阵列。基于等式(6)，可以得到所有l-1个l阶二次/三次同余阵列，即依次令γ＝1,2,...,l-1。需要指出的是，与Costas阵列会遍历可用带宽内所有频率不同，l阶二次/三次同余阵列并不保证会遍历l个子带宽。对于某些频率，会在1个阵列对应时长内重复使用1；对于三次同余阵列，当满足l＝3m+2且m为正整数时，所构造的阵列会遍历可用带宽内所有频率。
表3给出从16个17阶二次同余阵列中挑选的4个二次同余阵列，它们任意两两之间具有较低的互相关性。有关二次/三次同余阵列的更多性质详见参考文献[8][9]，在此不做赘述。
表3 4个具有低互相关性的17阶二次同余阵列示例
3、多输入多输出(Multi Input Multi Output，MIMO)雷达
MIMO-ISAC系统感知精度的提升利用了MIMO雷达中虚拟阵列原理，下面进行简单介绍。考虑MIMO雷达发射阵列天线总数为M，各发射天线位置坐标为xT,m,m＝0,1,...,M-1，接收阵列天线总数为N，各接收天线坐标为xR,n,n＝0,1,...,N-1。假设各发射天线发射信号正交，则
其中sm(t),sk(t)分别表示第m个天线和第k个天线的发送信号，δmk为狄拉克函数。此时接收机每个接收天线使用M个匹配滤波器分离发射信号，因此接收机总共得到NM个接收信号。考虑1个远场点目标，则第n个接收天线的第m个匹配滤波器得到的目标响应可以表示为：
其中ut为1个从雷达发射机指向点目标的单位向量，α(t)为点目标的反射系数，λ为发射信号载频波长。可以看到反射信号的相位由发射天线和接收天线共同确定。等效地，等式(8)的目标响应与1个天线数为NM的阵列得到的目标响应完全相同，该等效阵列天线位置坐标为：
{xT,m+xR,n|m＝0,1,...,M-1；n＝0,1,...,N-1},      (9)
称该天线数为NM的阵列为虚拟阵列(Virtual Array，VA)。
图2给出一个M＝3和N＝4的MIMO雷达配置以及对应的虚拟阵列示意图。MIMO雷达实际部署时，通过合理设置发射阵列和/或接收阵列位置，仅仅通过N+M个物理天线，就能构造出包含NM个互不重叠的虚拟天线的阵列。由于虚拟阵列往往能够形成更大的阵列孔径，因此能够获得更好的角度分辨率。
更一般地，若存在L个目标，假设各发射天线发送信号存在一定相关性，MIMO雷达经过距离-多普勒滤波之后的(这里只分析角度估计，假设时延和多普勒参数在接收机侧已进行过补偿)接收信号为：
其中αl为第l个目标反射系数和反射时延，T0为发送信号长度，且



s(t)＝[s1(t),...,sM(t)]T,      (14)
A(θ)为N×M的MIMO雷达导向矢量矩阵，等式(12)(13)分别为接收和发射阵列导向矢量，τT,m,m＝0,1,...,M-1和τR,n,n＝0,1,...,N-1分别为发射和接收阵列相对参考点的信号传播时延。各发射天线发送信号相关矩阵为：
其中βij为第i个发射天线和第j个发射天线发送信号的相关系数。
可以证明，等式(10)对参数θ的最大似然估计可以根据NM×1向量得到。
一般为了接收机算法复杂度的简化，希望η为统计独立的充分统计量，见参考文献[5]。对发送信号相关矩阵做特征值分解，有Rs＝UΛUH，相应地，实际发送信号可以看作是一组正交信号的线性变换，即
代入等式(10)且由于得到
相应地，等式(16)变为：
其中
为维度为NM×1的等效虚拟导向矢量。
对于相控阵雷达，各发射天线信号是相干的，此时Rs＝uuH仅包含1个非零特征值，所以此时
此时虚拟阵列的有效阵元数仅为N。对于各发射天线发射信号完全正交的MIMO雷达，有Rs＝IM×M以及UΛ1/2＝IM×M，此时
由上可见，各发射天线发送信号间的正交性(相关性)会影响MIMO雷达的虚拟阵列有效阵元数，进而影响接收机侧角度估计性能。
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息发送方法、信息接收方法、装置及相关设备进行详细地说明。
参见图3，图3是本申请实施例提供的一种信息发送方法的流程图，如图3所示，信息发送方法包括以下步骤：
步骤101、第一通信设备向第一感知节点和/或第二感知节点发送第一配置信息，其中，所述第一配置信息用于确定第一信号，所述第一信号由至少一个基本图样构成，且所述第一信号用于感知或者通信感知一体化。
其中，第一信号用于感知时，第一信号可以描述为感知信号；第一信号用于通信感知一体化时，第一信号可以描述为感知信号，或者通信感知一体化信号，或者通感一体化信号，等等，本实施例对此不进行限定。
一种实施方式中，所述第一配置信息可以用于动态配置第一信号。第一配置信息可以描述为第一信号配置参数信息，或者感知信号配置参数信息，或者通信感知一体化信号配置参数信息，或者通感一体化信号配置参数信息，等等，本实施例对第一配置信息的名称不进行限定。
一种实施方式中，第一通信设备确定第一配置信息，向第一感知节点和/或第二感知节点发送第一配置信息。
一种实施方式中，第一感知节点接收第一通信设备发送的第一配置信息；所述第一感知节点基于所述第一配置信息发送第一信号。示例地，第一感知节点基于第一配置信息动态配置第一信号，向第二感知节点发送第一信号。
一种实施方式中，第二感知节点接收第一通信设备发送的第一配置信息；所述第二感知节点基于所述第一配置信息接收第一信号。
需要说明的是，发送和/或接收第一信号的节点可以称为感知节点。对感知节点进行指示、调度、控制，以及感知结果计算的设备，可以是感知节点中的某个节点，也可以是核心网中的设备，例如感知功能网元(Sensing Function，SF)、接入和移动管理功能(Access and Mobility Management Function，AMF)、核心网中的感知应用服务器等，可以将上述核心网中的设备称为第一设备。可以将确定所述第一配置信息的设备称为第一通信设备，第一通信设备可能是任意感知节点或者第一设备；为了区分，可以将计算感知测量量测量值/感知结果的设备称为第二通信设备，第二通信设备也可能是任意感知节点或者第一设备；第一通信设备和第二通信设备可以是同一个设备，也可以是不同的设备。
另外，第一通信设备也可以描述为第一计算设备，第二通信设备也可以描述为第二计算设备。
应理解，第一信号的信号图样会影响感知接收机匹配滤波器的输出，进而影响感知性能。相关技术中，NR的参考信号导频图样固定，即便能够同时配置不同参考信号进行组合，灵活性仍十分受限。更重要的是，基于NR参考信号难以满足丰富多变的感知/通感业务需求，限制了感知/通感业务性能上界。
本实施例中，对于感知节点A发送第一信号，感知节点B接收的感知方式：当感知节点A配置为单天线端口时，若感知节点B采用匹配滤波对接收信号进行处理，感知节点A采用第一配置信息实现第一信号配置，可以根据感知需求、感知/通感一体化服务质量(Quality of Service，QoS)、通信QoS、历史感知测量量测量值/历史感知结果、感知/通感一体化可用资源等至少一项因素，确定第一信号。相对于采用固定信号图样，能够提升感知性能。
进一步地，当感知节点A配置为多天线端口时，为了使感知节点B能够区分感知节点A不同天线端口信号，提升感知性能，需要感知节点A不同天线端口信号彼此正交或准正交，即不同端口间信号互相关性小于预设门限。采用第一配置信息实现第一信号动态配置，能够保证各天线端口第一信号良好的正交性，提高时频资源率用率，保证多端口感知性能。
本实施例通过第一配置信息动态配置第一信号，能够实现灵活配置第一信号，能够满足多种感知/通感业务需求，提高时频资源利用率；且本实施例中，感知/通感一体化接收机采用匹配滤波处理，能够提升MIMO感知和多节点协作的整体感知性能。
在本申请实施例中，第一通信设备向第一感知节点和/或第二感知节点发送第一配置信息，其中，所述第一配置信息用于确定第一信号，所述第一信号由至少一个基本图样构成，且所述第一信号用于感知或者通信感知一体化，这样，能够支持通过第一配置信息动态配置用于感知或者通信感知一体化的第一信号，从而能够提高感知或通信感知一体化性能。

下面通过四个具体的实施例对本申请实施例提供的信息发送方法、信息接收方法进行说明：
实施例一：基于感知需求的感知信号配置
该实施例实现基于感知需求进行感知信号配置。例如，感知需求为对某一个速度范围、距离范围的目标进行感知(例如对某个区域的人流检测)。在这个实施例中，感知节点为2个不同的基站(如基站1、基站2)，第一计算设备和第二计算设备均为感知功能网元。具体流程可以描述如下：
(11)：感知应用服务器向感知功能网元发送感知需求，感知需求是对某个区域的人流进行检测；
(12)：感知功能网元获取第一信息，第一信息包括：感知需求、感知节点能力信息、感知先验信息等；
(13)：感知功能网元基于感知节点能力信息确定感知节点。例如，确定感知信号发送设备为基站1，感知信号接收设备为基站2，则所述感知节点能力信息由基站1、基站2发送给感知功能网元；
(14)：感知功能网元基于第一信息确定感知信号配置参数信息，并将所述感知信号配置参数信息发送给基站1和基站2；
应注意，本实施例中感知业务为人流检测，行人的移动速度范围大约在1.2～2.5m/s，3.5GHz信号载频下对应多普勒为14.0～29.2Hz。假设基站1到感知区域、感知区域到基站2的距离之和约为100m，感知区域大小约为30×30㎡。一种可选实施方案为，第二条件包括在距离-多普勒谱的70-130m，14.0～29.2Hz范围内，要求感知信号的模糊函数旁瓣总功率低于第一门限。通过这种设计，使得感知性能受干扰和噪声的影响降至最小，提高了行人的检测概率。
(15)：基于接收到的感知信号配置参数信息，基站1发送感知信号，基站2接收感知信号，执行感知业务；
(16)：基于接收到的感知信号，基站2获取感知测量量测量值，并将感知测量量测量值上报给感知功能网元；
(17)：基于接收到的感知测量量测量值，感知功能网元计算得到感知结果，并将其反馈至感知应用服务器；
可选地，感知功能网元基于感知测量量测量值和/或感知结果，更新第一信息，并基于更新后的第一信息重新确定感知信号配置参数信息。网络重新执行步骤(14)～(17)。
实施例二：基于感知/通感一体化QoS的感知信号配置
该实施例实现基于通感一体化QoS进行通感一体化信号配置。例如，通感一体化业务为对某一个无源目标(例如车辆)进行测速，同时UE与基站间进行通信。在这个实施例中，感知节点为UE和基站，第一计算设备为感知功能网元，第二计算设备为基站。具体流程可以描述如下：
(21)：感知应用服务器向感知功能网元发送通感一体化QoS，其中，通感一体化QoS至少包括：通感质量标识(Sensing&Communication Quality Identifier，SCQI)、通感业务类型、感知分辨率、通信包延迟预算、通信最大误包率等；其中通感业务类型是车辆定位和数据通信；
(22)：感知功能网元获取第一信息，第一信息包括：通感一体化QoS、感知节点能力信息、感知先验信息等；
(23)：感知功能网元基于感知节点能力信息确定感知节点。例如，确定通感一体化信号发送设备为基站，通感一体化信号接收设备为UE，则所述感知节点能力信息由UE、基站发送给感知功能网元；
(24)：感知功能网元基于第一信息确定通感一体化信号配置参数信息，并将所述通感一体化信号配置参数信息发送给基站和UE；
应注意，本实施例中感知业务为车辆测速，车辆的移动速度范围大约在30～120km/h，3.5GHz信号载频下对应多普勒为97.2～388.9Hz。假设基站和UE的位置根据感知先验信息已知。一种可选实施方案为，感知功能网元根据通感一体化QoS，确定通感一体化信号的基本图样类型(例如为Type 2)、基本图样阶数、基本图样周期、通感一体化信号持续时间等，保证所测多普勒频率在最大无模糊范围内，且满足感知分辨率、通信包延迟预算等通感一体化QoS指标。通过这种设计，使得感知和通信资源得到合理分配，且信号配置灵活，提升了通感一体化性能；
(25)：基于接收到的通感一体化信号配置参数信息，基站发送通感一体化信号，UE接收通感一体化信号，执行通感一体化业务；
(26)：基于接收到的通感一体化信号，UE接收下行通信数据的同时，获取感知测量量测量值，并将感知测量量测量值上报给基站；
(27)：基于接收到的感知测量量测量值，基站计算得到感知结果，并将其反馈至感知应用服务器；
可选地，基站将获得的感知测量量测量值和/或感知结果发送给感知功能网元，感知 功能网元基于感知测量量测量值和/或感知结果，更新第一信息，并基于更新后的第一信息重新确定通感一体化信号配置参数信息。网络重新执行步骤(24)～(27)。
实施例三：基于MIMO雷达的感知信号配置
该实施例实现基于MIMO雷达的感知信号配置。例如，感知业务为对某一个无源目标(例如车辆)进行测速和定位。在这个实施例中，感知节点为基站，第一计算设备为感知功能网元，第二计算设备为基站。具体流程可以描述如下：
(31)：感知应用服务器向感知功能网元发送感知需求及感知QoS，感知需求是对某个区域的车辆进行测速和定位；
(32)：感知功能网元获取第一信息，第一信息包括：感知节点可用于感知业务的时频资源、感知QoS、感知节点能力信息、感知先验信息等；
应理解，基站上行可能存在与其他UE的通信业务，因此自发自收感知业务的时频资源应与上行通信业务的时频资源错开，否则上行通信信号与感知回波信号见可能存在干扰。
(33)：感知功能网元基于感知节点能力信息确定感知节点。例如，确定通感一体化信号发送设备为基站，通感一体化信号接收设备为同一个基站，则所述感知节点能力信息由基站发送给感知功能网元；
(34)：感知功能网元基于第一信息确定感知信号配置参数信息，并将所述感知信号配置参数信息发送给基站；
应注意，本实施例中感知业务为车辆测速和定位，因此感知测量量包括车辆回波的多普勒频率、时延、到达角。假设基站的位置、朝向根据感知先验信息已知。一种可选实施方案为，感知功能网元根据第一信息，确定基站至少2个天线端口的感知信号的基本图样类型(例如为Type 5和/或Type 6)、基本图样阶数、基本图样周期、通感一体化信号持续时间等，保证不同端口信号互相关性低于第二门限，且多普勒频率、时延、到达角满足感知分辨率以及无模糊要求。通过这种设计，使得MIMO感知信号配置灵活，提升了感知性能；
(35)：基于接收到的感知信号配置参数信息，基站发送感知信号，并接收信号回波，执行感知业务；
(36)：基于接收到的感知信号，基站获取感知测量量测量值，并计算得到感知结果，将其反馈至感知应用服务器；
可选地，基站将获得的感知测量量测量值和/或感知结果发送给感知功能网元；感知功能网元基于感知测量量测量值和/或感知结果，更新第一信息，并基于更新后的第一信息重新确定感知信号配置参数信息。网络重新执行步骤(34)～(36)。
实施例四：基于多节点协作的感知信号配置
该实施例实现基于多节点协作的感知/通感一体化信号配置。例如，感知业务为对某 一个无源目标(例如车辆)进行定位和轨迹追踪。在这个实施例中，感知节点包括至少2个UE(例如UE1和UE2)和1个基站，第一计算设备和第二计算设备均为同1个基站。具体流程可以描述如下：
(41)：感知应用服务器向基站或感知功能网元发送感知需求，感知需求是对某个区域的车辆进行定位和轨迹追踪；
(42)：基站获取第一信息，第一信息包括：感知需求、感知节点能力信息、感知先验信息、感知/通感一体化QoS等；所述基站可以由感知应用服务器或感知功能网元确定；
(43)：基站基于感知节点能力信息确定感知节点。例如，确定感知/通感一体化信号发送设备为UE 1及UE 2，感知/通感一体化信号接收设备为基站，则所述感知节点能力信息由UE 1及UE2发送给基站；
(44)：基站基于第一信息确定感知/通感一体化信号配置参数信息，并将所述感知/通感一体化信号配置参数信息发送给UE 1及UE 2；
应注意，本实施例中感知业务为车辆定位和轨迹追踪，因此感知测量量可以是车辆回波的多普勒频率、时延、到达角中至少一项。假设基站、UE 1、UE 2的位置根据感知先验信息已知。一种可选实施方案为，基站根据第一信息，确定UE 1、UE 2发送的感知/通感一体化信号的基本图样类型(例如为Type 4、Type 5、Type 6、Type 7任意至少一种)、基本图样阶数、基本图样周期、感知/通感一体化信号持续时间等，保证不同UE间发射的信号互相关性低于第三门限，且多普勒频率、时延、到达角任意至少一项满足感知分辨率以及无模糊要求。通过这种设计，降低了多节点间信号的相互干扰，提升了多节点协作感知的整体性能；
需要指出的是，上述仅以2个发送节点(UE)作为例子，可以推广到更多节点参与感知的情况；且不一定所有节点均有通信业务，例如上述UE 1仅执行感知业务，UE 2执行通感一体化业务；
(45)：基于接收到的感知/通感一体化信号配置参数信息，UE 1、UE 2发送感知/通感一体化信号，基站接收感知/通感一体化信号，执行感知/通感一体化业务；
(46)：基于接收到的感知/通感一体化信号，基站获取感知测量量测量值，并计算得到感知结果，将其反馈至感知应用服务器；
可选地，基站基于感知测量量测量值和/或感知结果，更新第一信息，并基于更新后的第一信息重新确定感知信号配置参数信息。网络重新执行步骤(44)～(46)。
