一种确定信号到达角的方法、装置和系统A method, device and system for determining the angle of arrival of a signal

技术领域technical field

本申请实施例涉及通信技术领域，尤其涉及一种确定信号到达角的方法、装置和系统。The embodiments of the present application relate to the field of communication technologies, and in particular, to a method, apparatus, and system for determining the angle of arrival of a signal.

背景技术Background technique

随着无线通信需求的不断增长，更多的频谱资源被划分为无线通信所用。其中，毫米波频段(30GHz—300GHz)可以提供高达多个GHz的连续带宽资源，已经被IEEE 802.11ad等无线局域网和无线个域网标准所采用。第三代合作伙伴计划(3rd GenerationPartnership Project，3GPP)标准在第15版本(Release 15，R15)中也开始支持毫米波通信，标志着毫米波通信成为了第五代(5-Generation，5G)移动通信系统中的关键技术之一。鉴于毫米波信号频率高、波长短，在空气中传播时会经历严重的路径损耗。为了克服毫米波路径损耗，需要采用基于阵列天线的波束赋形技术将信号能量集中在一个特定方向上，从而提高在这个方向上的天线增益。With the increasing demand for wireless communication, more spectrum resources are allocated for wireless communication. Among them, the millimeter wave frequency band (30GHz-300GHz) can provide continuous bandwidth resources up to multiple GHz, and has been adopted by wireless local area network and wireless personal area network standards such as IEEE 802.11ad. The 3rd Generation Partnership Project (3GPP) standard also began to support millimeter wave communication in Release 15 (R15), marking that millimeter wave communication has become the fifth generation (5-Generation, 5G) mobile communication One of the key technologies in the communication system. Given the high frequencies and short wavelengths of mmWave signals, they experience severe path loss as they travel through the air. In order to overcome the millimeter wave path loss, it is necessary to use the beamforming technology based on the array antenna to concentrate the signal energy in a specific direction, thereby improving the antenna gain in this direction.

现有技术中，可以通过如下方式实现波束训练，通过设计多级波束赋形码本，支持形成不同宽度的训练波束。在进行波束训练时，如图1中的(a)所示，终端和基站彼此使用宽波束进行波束扫描，根据接收信号强度确定粗略波束指向，减小搜索空间范围。然后，如图1中的(b)所示，终端通过窄波束在减小之后的搜索空间内进行波束扫描，根据接收信号强度再次确定波束指向。最终，如图1中的(c)所示基站使用窄波束在终端确定的搜索空间内进行波束扫描，根据接收信号强度最终确定精确的波束指向。In the prior art, beam training can be implemented in the following manner, by designing a multi-level beamforming codebook to support the formation of training beams of different widths. During beam training, as shown in (a) of Figure 1, the terminal and the base station use wide beams to scan each other, determine the rough beam direction according to the received signal strength, and reduce the search space range. Then, as shown in (b) of FIG. 1 , the terminal performs beam scanning in the reduced search space through the narrow beam, and determines the beam pointing again according to the received signal strength. Finally, as shown in (c) in FIG. 1 , the base station uses narrow beams to perform beam scanning in the search space determined by the terminal, and finally determines the precise beam pointing according to the received signal strength.

但是，多级码本的设计要求阵列天线具有多个连接射频前端和基带的射频(RadioFrequency，RF)链路(Chain)，但由于射频链路功率消耗大，实现成本高，一般在毫米波通信系统中，射频链路的数量有限，难以形成满足要求的多级码本和相应的天线增益方向图；其次，多级码本法依靠接收信号强度判断波束指向，信号到达角估计的精确度和对多径的分辨能力受限于波束宽度。However, the design of the multi-level codebook requires the array antenna to have multiple radio frequency (RadioFrequency, RF) chains (Chains) connecting the RF front-end and the baseband. In the system, the number of radio frequency links is limited, and it is difficult to form a multi-level codebook and corresponding antenna gain pattern that meet the requirements; secondly, the multi-level codebook method relies on the received signal strength to determine the beam pointing, the accuracy of the signal arrival angle estimation and the The ability to resolve multipath is limited by the beamwidth.

发明内容SUMMARY OF THE INVENTION

本申请实施例提供一种确定信号到达角的方法、装置和系统，用以通过准确的计算信号到达角，从而提高波束训练的效率。Embodiments of the present application provide a method, device and system for determining the angle of arrival of a signal, so as to improve the efficiency of beam training by accurately calculating the angle of arrival of the signal.

为了达到上述目的，本申请实施例提供如下技术方案：In order to achieve the above purpose, the embodiments of the present application provide the following technical solutions:

第一方面，本申请实施例提供一种确定信号到达角的方法，包括：接收设备依次切换多个接收波束接收发送设备在参考信号资源上发送的多次相同的参考信号，得到多次接收信号。多个接收波束的波束方向不同，多个接收波束的波束方向与多次参考信号一一对应。接收设备对多次接收信号执行数字信号处理，得到多次接收信号对应的接收信号矩阵。接收设备对接收信号矩阵中的所有信号元素执行波束映射操作，得到波束映射矩阵。接收设备根据波束映射矩阵以及预设算法，确定发送设备的信号到达角。In a first aspect, an embodiment of the present application provides a method for determining the angle of arrival of a signal, including: a receiving device sequentially switches multiple receiving beams to receive multiple identical reference signals sent by a sending device on a reference signal resource, and obtain multiple received signals . The beam directions of the multiple receiving beams are different, and the beam directions of the multiple receiving beams are in one-to-one correspondence with the multiple reference signals. The receiving device performs digital signal processing on the received signals for multiple times to obtain a received signal matrix corresponding to the multiple received signals. The receiving device performs beam mapping operations on all signal elements in the received signal matrix to obtain a beam mapping matrix. The receiving device determines the signal arrival angle of the transmitting device according to the beam mapping matrix and the preset algorithm.

本申请实施例提供的一种确定信号到达角的方法，由于接收设备通过依次切换多个接收波束以接收发送设备在参考信号资源上发送的多次相同的参考信号，得到多次接收信号，由于信号到达角的估计不依赖波束的精细扫描，这样接收设备在探测发送设备发送的多次参考信号时，无需进行精细的波束扫描，通过依次切换多个接收波束便可以实现粗波束扫描。然后依赖数字信号处理以及预设算法便可以估计信号到达角。这样可以大大减小波束训练开销，实现快速波束训练，从而提高毫米波通信系统的可靠性和稳定性，还有助于实现更为精细的拓扑管理、路由计算和移动性管理。此外，对于本申请实施例提供的方法不仅仅依赖接收信号强度判断最优波束指向，而是利用对多次接收信号执行数字信号处理以估计出AoA，如此一来，既可以获得比基于接收信号强度的波束训练方法更高的精度，还无需进行精细的波束扫描，从而实现既快速又准确的波束训练性能。In the method for determining the angle of arrival of a signal provided by the embodiment of the present application, the receiving device obtains multiple received signals by sequentially switching multiple receiving beams to receive the same reference signal sent by the sending device on the reference signal resource multiple times. The estimation of the angle of arrival of the signal does not depend on the fine scanning of the beam, so that the receiving device does not need to perform the fine beam scanning when detecting multiple reference signals sent by the sending device, and can realize the coarse beam scanning by sequentially switching multiple receiving beams. The angle of arrival of the signal can then be estimated by relying on digital signal processing and preset algorithms. In this way, beam training overhead can be greatly reduced, and fast beam training can be achieved, thereby improving the reliability and stability of the millimeter-wave communication system, and also helping to achieve more refined topology management, routing calculation, and mobility management. In addition, the method provided by the embodiment of the present application does not only rely on the received signal strength to determine the optimal beam pointing, but uses digital signal processing on multiple received signals to estimate the AoA. Intensity beam training methods provide greater accuracy and also eliminate the need for fine beam scanning, resulting in fast and accurate beam training performance.

在介绍本申请实施例之前，首先解释本申请实施例中涉及到的相关名词：Before introducing the embodiments of the present application, first explain the related terms involved in the embodiments of the present application:

射频链路(RF chain)：连接射频天线与基带数字信号处理单元的一系列器件的总称。一般包括模数转换器(Analog to Digital Converter，ADC)/数模转换器(Digital toAnalog Converter，DAC)、混频器、振荡器、滤波器等。RF chain: The general term for a series of devices connecting the RF antenna and the baseband digital signal processing unit. Generally, it includes an analog-to-digital converter (Analog to Digital Converter, ADC)/digital-to-analog converter (Digital to Analog Converter, DAC), a mixer, an oscillator, a filter, and the like.

阵列天线：由多个天线按照一定的几何结构排列形成的一个天线阵列，包括一维的线性阵列天线，二维的矩形阵列天线。其中，每个天线又称为阵元。例如，多个天线可以按照预设间距排列形成的一个天线阵列。Array antenna: an antenna array formed by arranging multiple antennas according to a certain geometric structure, including one-dimensional linear array antennas and two-dimensional rectangular array antennas. Among them, each antenna is also called an array element. For example, a plurality of antennas can be arranged according to a preset interval to form an antenna array.

波束赋形(beamforming)：通过调节馈送到阵列天线的每个阵元的信号的相位(有时也调节幅度)，也就是给每个阵元的信号进行加权，达到让信号能量聚集到某一个方向的作用，即形成一个方向性的波束。Beamforming: By adjusting the phase (and sometimes the amplitude) of the signal fed to each array element of the array antenna, that is, weighting the signal of each array element, so that the signal energy can be concentrated in a certain direction , that is, to form a directional beam.

数字波束赋形(digital beamforming)架构：阵列天线中的每个阵元都通过一个射频链路与基带数字信号处理单元相连，因此，波束赋形完全通过基带数字信号处理的方式完成。如图2a所示。在图2a中阵元1、阵元2、…、阵元N中每个阵元与一个RF chain连接，即在图2a中具有N个RF chain。该N个RF chain与基带数字信号处理单元相连。该基带数字信号处理单元用于进行数字波束赋形。Digital beamforming (digital beamforming) architecture: Each element in the array antenna is connected to the baseband digital signal processing unit through a radio frequency link. Therefore, beamforming is completely completed by baseband digital signal processing. As shown in Figure 2a. In Fig. 2a, each of thearray elements 1, 2, . . . , and N is connected to one RF chain, that is, there are N RF chains in Fig. 2a. The N RF chains are connected to the baseband digital signal processing unit. The baseband digital signal processing unit is used for digital beamforming.

模拟波束赋形(analog beamforming)架构：一个阵列天线只使用一个射频链路与基带信号处理单元相连，其中的每个阵元都接有一个移相器，用来控制每路信号的相位偏移，即波束赋形在射频模拟域完成。如图2b所示，在图2b中N个阵元中每个阵元与一个移相器连接，即在图2b中具有N个移相器。该N个移相器与一个RF chain连接，该RF chain与基带信号处理单元连接。Analog beamforming (analog beamforming) architecture: an array antenna uses only one RF link to connect to the baseband signal processing unit, and each array element is connected to a phase shifter to control the phase offset of each signal , that is, beamforming is done in the RF analog domain. As shown in Fig. 2b, each of the N array elements in Fig. 2b is connected to a phase shifter, that is, there are N phase shifters in Fig. 2b. The N phase shifters are connected to an RF chain, which is connected to the baseband signal processing unit.

混合波束赋形(hybrid beamforming)架构：一个阵列天线使用多个射频链路与基带信号处理单元相连，其中射频链路的数目小于天线阵元的数目，波束赋形通过射频模拟域的移相器和数字域的信号处理共同完成。如图2c所示，在图2c中N个阵元中每个阵元与模拟波束赋形单元连接，利用射频模拟域的移相器控制每路信号的相位偏移后经过I个RFchain与基带信号处理单元连接。Hybrid beamforming architecture: an array antenna is connected to the baseband signal processing unit using multiple radio frequency links, where the number of radio frequency links is less than the number of antenna elements, and the beamforming is passed through a phase shifter in the radio frequency analog domain It is done together with signal processing in the digital domain. As shown in Figure 2c, in Figure 2c, each of the N array elements is connected to an analog beamforming unit, and the phase shifter in the RF analog domain is used to control the phase shift of each signal through I RFchain and baseband. Signal processing unit connection.

示例性的，图2a-图2c中各个阵元之间以均匀线性阵列(Uniform Linear Array，ULA)为例进行描述，即各个阵元之间的间距相等。当然在实际过程中各个阵元之间的间距可以相等，也可以不相等，本申请实施例对此不做限定。Exemplarily, in FIG. 2a- FIG. 2c, each array element is described by taking a uniform linear array (Uniform Linear Array, ULA) as an example, that is, the spacing between each array element is equal. Of course, in the actual process, the distances between the array elements may be equal or unequal, which is not limited in this embodiment of the present application.

多信号分类算法(Multiple Signal Classification，MUSIC)算法是一种高分辨率的基于阵列天线的信号到达角(Angle of Arrival，AoA)估计算法。如图3所示，传统的MUSIC算法适用于数字波束赋形架构，每个阵元收到的射频信号通过各自的RF chain被转换为数字基带信号，MUSIC算法对这些数字基带信号进行处理，估计出信号AoA。The Multiple Signal Classification (MUSIC) algorithm is a high-resolution angle of arrival (Angle of Arrival, AoA) estimation algorithm based on an array antenna. As shown in Figure 3, the traditional MUSIC algorithm is suitable for the digital beamforming architecture. The RF signals received by each array element are converted into digital baseband signals through their respective RF chains. The MUSIC algorithm processes these digital baseband signals and estimates out signal AoA.

具体过程如下：如图3中的(a)所示，以平面波的信号AoA为θ_x为例，该平面波以θ_x到达接收机的ULA天线。该ULA天线由N个在一条直线上等间距排列的阵元组成，相邻阵元之间的间距为d。定义任意信号AoA θ以阵列的法线方向为参考方向。当信号AoA为法线方向时，θ＝0°。当信号AoA顺时针旋转时，θ增大。当信号AoA逆时针旋转时，θ减小。因此，-90°＜θ＜90°。当0＜θ＜90°时，平面波最先到达阵元N，平面波最后到达阵元1，阵元n与阵元1之间的波程差为x_n＝(n-1)dsinθ,n＝1,...,N。阵元序号越大，相位越超前，阵元n超前阵元1的相位差为

同理，当-90°＜θ＜0°时，阵元n超前阵元1的相位差为：

此时θ和△Φ_n为负值，其中，λ为信号载波的波长。为了描述上述性质，以阵元1为参考阵元，定义均匀直线天线阵的阵列响应矢量为：The specific process is as follows: As shown in (a) of FIG. 3 , taking the signal AoA of the plane wave as θ_x as an example, the plane wave reaches the ULA antenna of the receiver at θ_x . The ULA antenna consists of N array elements arranged at equal intervals on a straight line, and the interval between adjacent array elements is d. Define the arbitrary signal AoA θ with the normal direction of the array as the reference direction. When the signal AoA is in the normal direction, θ=0°. As the signal AoA rotates clockwise, θ increases. As the signal AoA rotates counterclockwise, θ decreases. Therefore, -90°<θ<90°. When 0<θ<90°, the plane wave arrives at array element N first, and the plane wave arrives at array element 1 last. The wave path difference between array element n and array element 1 is x_n =(n-1)dsinθ,n= 1,...,N. The larger the array element number is, the more advanced the phase is. The phase difference of the array element n ahead of the array element 1 is:

Similarly, when -90°<θ<0°, the phase difference of array element n ahead of array element 1 is:

At this time, θ and_ΔΦn are negative values, where λ is the wavelength of the signal carrier. In order to describe the above properties, with array element 1 as the reference array element, the array response vector of the uniform linear antenna array is defined as:

对于一个信号AoA为θ_x的接收信号，其基带离散时间信号矢量模型可以表示为：y(m)＝s(m)a(θ_x)+n(m)。其中，m表示采样时间，s(m)表示阵元1接收到的复数采样信号，n(m)表示噪声矢量。MUSIC算法利用接收到的阵列信号矢量y(m)来估计θ_x，具体步骤如下述步骤1-步骤5。For a received signal whose signal AoA is θ_x , its baseband discrete-time signal vector model can be expressed as: y(m)=s(m)a(θ_x )+n(m). Among them, m represents the sampling time, s(m) represents the complex sampling signal received by the array element 1, and n(m) represents the noise vector. The MUSIC algorithm uses the received array signal vector y(m) to estimate θ_x , and the specific steps are as follows in steps 1-5.

步骤1、用M个采样点估计接收信号矢量的互相关矩阵。Step 1. Use M sampling points to estimate the cross-correlation matrix of the received signal vector.

其中，R_yy表示互相关矩阵，M表示采样点数量。

Among them, R_yy represents the cross-correlation matrix, and M represents the number of sampling points.

步骤2、分解互相关矩阵R_yy的特征值。Step 2. Decompose the eigenvalues of the cross-correlation matrix R_yy .

步骤4、在一定的角度范围内，对θ值进行搜索，求得空间谱函数

Step 4. Search the θ value within a certain angle range to obtain the spatial spectral function

步骤5、利用上述正交性可知，空间谱函数的峰值所对应的θ值即为θ_x的估计值。Step 5. Using the above-mentioned orthogonality, it can be known that the θ value corresponding to the peak value of the spatial spectral function is the estimated value of θ_x .

为了降低计算复杂度，在进行数字信号处理时，可以先进行数字波束赋形，将接收信号从阵元空间转换为波束空间(降维)。如图3中的(b)所示，数字波束赋形矩阵W的维度是N×K，其中K＜N，只要其满足条件W^HW＝I，上述MUSIC算法所利用的正交关系就依然满足，MUSIC算法可以利用降维之后的信号估计出信号AoA。In order to reduce the computational complexity, when digital signal processing is performed, digital beamforming can be performed first to convert the received signal from the array element space to the beam space (dimension reduction). As shown in (b) of Figure 3, the dimension of the digital beamforming matrix W is N×K, where K<N, as long as it satisfies the condition W^H W=I, the orthogonal relationship used by the above MUSIC algorithm is still Satisfaction, the MUSIC algorithm can use the signal after dimension reduction to estimate the signal AoA.

Among them, L is a positive integer.

应理解，如果参考信号的重复次数为K，则发送设备在参考信号资源上将同一个参考信号重复K次。K为大于或等于1的整数。It should be understood that if the number of repetitions of the reference signal is K, the transmitting device repeats the same reference signal K times on the reference signal resource. K is an integer greater than or equal to 1.

步骤103、接收设备依次切换多个接收波束接收发送设备在参考信号资源上发送的多次相同的参考信号，得到多次接收信号。多个接收波束的波束方向不同，多个接收波束的波束方向与多次参考信号一一对应。Step 103: The receiving device sequentially switches the multiple receiving beams to receive the same reference signal sent by the sending device on the reference signal resource for multiple times to obtain multiple received signals. The beam directions of the multiple receiving beams are different, and the beam directions of the multiple receiving beams are in one-to-one correspondence with the multiple reference signals.

例如，接收设备可以为如图4中的接入设备。For example, the receiving device may be the access device as shown in FIG. 4 .

应理解，同一个参考信号通过不同的传播路径传播至接收设备，接收设备对同一个参考信号使用多个不同的接收波束接收时，得到的多次接收信号不同。例如，该多次接收信号的采样点序列在幅度和/或相位上存在差异。It should be understood that the same reference signal is propagated to the receiving device through different propagation paths, and when the receiving device uses multiple different receiving beams to receive the same reference signal, the multiple received signals obtained are different. For example, the sampling point sequences of the multiple received signals differ in amplitude and/or phase.

在一种实现中，步骤103具体可以通过以下方式实现：接收设备通过依次切换多个接收波束，以采用多个接收波束中每个接收波束接收每个接收波束各自对应的参考信号。In one implementation, step 103 may be specifically implemented in the following manner: the receiving device switches the multiple receive beams in sequence, so as to use each receive beam in the multiple receive beams to receive the reference signal corresponding to each receive beam.

应理解，该多个接收波束中不同的接收波束具有不同的波束方向。当然，该不同的接收波束的接收方向可以存在部分重叠，换句话说不同的接收波束的接收方向可以具有交集。It should be understood that different receiving beams in the plurality of receiving beams have different beam directions. Of course, the receiving directions of the different receiving beams may partially overlap, in other words, the receiving directions of the different receiving beams may have an intersection.

示例性的，以发送设备在同一个参考信号资源1上向接收设备重复发送多次相同的参考信号为例，接收设备具有接收波束1、接收波束2以及接收波束3。其中，接收波束1用于接收发送设备在参考信号资源1上发送的第1次参考信号，接收波束2用于接收发送设备在参考信号资源1上发送的第2次参考信号，接收波束3用于接收发送设备在参考信号资源1上发送的第3次参考信号。例如，接收设备采用接收波束1接收第1次参考信号之后，可以将接收波束从接收波束1切换至接收波束2以接收发送设备在参考信号资源1上发送的第2次参考信号，在接收到第2次参考信号之后可以将接收波束从接收波束2切换至接收波束3，以采用接收波束3接收第3次参考信号。Exemplarily, taking the sending device repeatedly sending the same reference signal to the receiving device multiple times on the same reference signal resource 1 as an example, the receiving device has a receiving beam 1 , areceiving beam 2 , and a receiving beam 3 . Among them, receive beam 1 is used to receive the first reference signal sent by the sending device on reference signal resource 1, receivebeam 2 is used to receive the second reference signal sent by the sending device on reference signal resource 1, receive beam 3 is used for It is used to receive the third reference signal sent by the sending device on the reference signal resource 1. For example, after the receiving device uses receive beam 1 to receive the first reference signal, it can switch the receive beam from receive beam 1 to receivebeam 2 to receive the second reference signal sent by the transmitting device on reference signal resource 1. After the second reference signal, the receive beam may be switched from receivebeam 2 to receive beam 3 to receive the third reference signal using receive beam 3 .

步骤104、接收设备对多次接收信号执行数字信号处理，得到多次接收信号对应的接收信号矩阵。Step 104: The receiving device performs digital signal processing on the multiple times of received signals to obtain a received signal matrix corresponding to the multiple times of received signals.

步骤105、接收设备对接收信号矩阵中的所有信号元素执行波束映射操作，得到波束映射矩阵。Step 105: The receiving device performs a beam mapping operation on all signal elements in the received signal matrix to obtain a beam mapping matrix.

步骤106、接收设备根据波束映射矩阵以及预设算法，确定发送设备的信号到达角。Step 106: The receiving device determines the angle of arrival of the signal of the transmitting device according to the beam mapping matrix and the preset algorithm.

本申请实施例提供的一种确定信号到达角的方法，由于接收设备通过依次切换多个接收波束以接收发送设备在参考信号资源上发送的多次相同的参考信号，得到多次接收信号，由于信号到达角的估计不依赖波束的精细扫描，这样接收设备在探测发送设备发送的多次参考信号时，无需进行精细的波束扫描，通过依次切换多个接收波束便可以实现粗波束扫描。然后依赖数字信号处理以及预设算法便可以估计信号到达角。这样可以大大减小波束训练开销，实现快速波束训练，从而提高毫米波通信系统的可靠性和稳定性，还有助于实现更为精细的拓扑管理、路由计算和移动性管理。此外，对于本申请实施例提供的方法不仅仅依赖接收信号强度判断最优波束指向，而是利用对多次接收信号执行数字信号处理以估计出AoA，如此一来，既可以获得比基于接收信号强度的波束训练方法更高的精度，还无需进行精细的波束扫描，从而实现既快速又准确的波束训练性能。In the method for determining the angle of arrival of a signal provided by the embodiment of the present application, the receiving device obtains multiple received signals by sequentially switching multiple receiving beams to receive the same reference signal sent by the sending device on the reference signal resource multiple times. The estimation of the angle of arrival of the signal does not depend on the fine scanning of the beam, so that the receiving device does not need to perform the fine beam scanning when detecting multiple reference signals sent by the sending device, and can realize the coarse beam scanning by sequentially switching multiple receiving beams. The angle of arrival of the signal can then be estimated by relying on digital signal processing and preset algorithms. In this way, beam training overhead can be greatly reduced, and fast beam training can be achieved, thereby improving the reliability and stability of the millimeter-wave communication system, and also helping to achieve more refined topology management, routing calculation, and mobility management. In addition, the method provided by the embodiment of the present application does not only rely on the received signal strength to determine the optimal beam pointing, but uses digital signal processing on multiple received signals to estimate the AoA. Intensity beam training methods provide greater accuracy and also eliminate the need for fine beam scanning, resulting in fast and accurate beam training performance.

在另一种可能的实施例中，如图6所示，本申请实施例提供的方法包括：步骤204、步骤205、步骤206、步骤207、步骤208以及步骤209。其中，步骤204-步骤209可以对应参考步骤101-步骤106中的描述，此处不再赘述。在图6所示的实施例中，在步骤204之前还包括：In another possible embodiment, as shown in FIG. 6 , the method provided by this embodiment of the present application includes: step 204 , step 205 , step 206 , step 207 , step 208 , and step 209 . Wherein, steps 204 to 209 may correspond to the descriptions in reference to steps 101 to 106, which will not be repeated here. In the embodiment shown in FIG. 6, before step 204, it further includes:

步骤201、接收设备获取切换波束码本和虚拟波束码本。Step 201: The receiving device acquires the switched beam codebook and the virtual beam codebook.

示例性的，切换波束码本可以为N×K维的码本

该N×K维的码本中每一列对应一个波束赋形向量，一个波束赋形向量对应了一组移相器相移值。N表示阵元数量，K个波束赋形向量形成的波束将整个扇区对应的角度范围分为K份。K的大小取决于阵元个数N以及当前小区内的信道状况，阵元数量越少、信道状况越好，则所需要的K越小。在已有的利用接收信号强度的波束训练机制中，波束训练的精度和波束切换或扫描的次数是成正比的，即波束切换的次数越多，波束训练的精度越高，要想获得较高的波束训练精度，就需要进行非常精细的波束切换或扫描，造成极大的开销。Exemplarily, the switching beam codebook may be an N×K-dimensional codebook

Each column in the N×K-dimensional codebook corresponds to a beamforming vector, and a beamforming vector corresponds to a set of phase shifter phase shift values. N represents the number of array elements, and the beam formed by the K beamforming vectors divides the angle range corresponding to the entire sector into K parts. The size of K depends on the number of array elements N and the channel condition in the current cell. The smaller the number of array elements and the better the channel condition, the smaller the required K is. In the existing beam training mechanism using received signal strength, the accuracy of beam training is proportional to the number of beam switching or scanning, that is, the more the number of beam switching, the higher the accuracy of beam training. If the beam training accuracy is high, very fine beam switching or scanning is required, resulting in great overhead.

本申请实施例中切换波束码本和虚拟波束码本可以是接收设备自己建立的，也可以是预存储在接收设备中的。In the embodiment of the present application, the switching beam codebook and the virtual beam codebook may be established by the receiving device itself, or may be pre-stored in the receiving device.

在本申请实施例中，由于不依赖接收信号强度确定波束指向，这里的波束切换次数可以大大降低，只依赖波束粗扫搜集上来的信号，就可以通过数字信号处理的方式估计出精确的信号AoA，用信号AoA指导波束训练。In the embodiment of the present application, since the beam pointing is determined without relying on the received signal strength, the number of beam switching here can be greatly reduced, and the accurate signal AoA can be estimated by digital signal processing only by relying on the signals collected by the rough scan of the beam. , using the signal AoA to guide beam training.

示例性的，虚拟波束码本可以为N×B维的码本

其中，L＜B＜K，L是发送设备上行传输时所经历的路径个数。B的大小取决于当前环境中散射体的多少，环境中的散射体造成的多径分量L越多，则所需要的B越大。换句话说，对于一个已经配置的B的值，意味着在当前配置下，可以估计出的上行传输路径个数最多为B-1。码本中的每一列满足关系

意味着虚拟波束码本中的每一列所对应的虚拟波束方向满足

其中，

c表示光速，f表示载波频率，d表示阵元间距。Exemplarily, the virtual beam codebook may be an N×B-dimensional codebook

Wherein, L<B<K, L is the number of paths experienced by the sending device during uplink transmission. The size of B depends on the number of scatterers in the current environment. The more multipath components L caused by the scatterers in the environment, the greater the required B. In other words, for an already configured value of B, it means that under the current configuration, the number of uplink transmission paths that can be estimated is at most B-1. Each column in the codebook satisfies the relation

It means that the virtual beam direction corresponding to each column in the virtual beam codebook satisfies

in,

c represents the speed of light, f represents the carrier frequency, and d represents the distance between the array elements.

相应的，本申请实施例步骤103或步骤206中的多个接收波束的波束方向由切换波束码本确定，切换波束码本包括一列或多列波束赋形向量，一列或多列波束赋形向量中每列波束赋形向量对应一组移相器相移值，每列波束赋形向量用于确定一个接收波束的波束方向。具体的，切换波束码本可以参考下述实施例中的描述，此处不再赘述。Correspondingly, the beam directions of the multiple receiving beams in step 103 or step 206 in this embodiment of the present application are determined by the switching beam codebook, and the switching beam codebook includes one or more columns of beamforming vectors, and one or more columns of beamforming vectors. Each column of beamforming vectors corresponds to a set of phase shifter phase shift values, and each column of beamforming vectors is used to determine the beam direction of a receiving beam. Specifically, for the switching beam codebook, reference may be made to the description in the following embodiments, which will not be repeated here.

由于本申请实施例提供的方法适用的场景不同，步骤206的具体实现也存在差异，因此下述将结合不同的场景分别介绍步骤206的具体实现：Since the applicable scenarios of the methods provided in the embodiments of the present application are different, the specific implementation of step 206 is also different. Therefore, the following will introduce the specific implementation of step 206 in combination with different scenarios:

场景1)、发送设备和接收设备的阵列天线架构为采用模拟波束赋形架构，发送设备和接收设备采用频分多址(frequency division multiple access，FDMA)技术或正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)技术通信。Scenario 1), the array antenna architecture of the transmitting device and the receiving device adopts an analog beamforming architecture, and the transmitting device and the receiving device adopt frequency division multiple access (frequency division multiple access, FDMA) technology or orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access (Orthogonal Frequency Division Multiple Access) Division Multiple Access, OFDMA) technology communication.

在一种可能的实现方式中，步骤206具体可以通过下述方式具体实现：接收设备使用不同指向的接收波束对该发送设备和其他发送设备同时发送的多次参考信号进行检测。具体来说，接收设备顺次使用切换波束码本W中的第1到第K个波束赋形向量来同时检测该发送设备和其他发送设备发送的多次参考信号。每个接收波束持续一个OFDM符号，该OFDM符号与发送设备发送的参考信号所占用的OFDM符号一一对应。最终得到多次参考信号中每次参考信号所对应的接收信号。例如，在场景1中每次参考信号所对应的接收信号可以为时域离散时间信号。该机制使得在模拟波束赋形架构下，也可以使用MUSIC算法进行AoA估计。具体来说，传统的MUSIC需要多个RF chain，使用数字波束赋形降低计算复杂度，数字波束赋形在基带完成。而在模拟波束赋形下，只能通过波束时分切换的方式，搜集对应着多个波束赋形向量的信号，利用这些信号作为传统MUSIC算法的输入参数，估计出AoA。In a possible implementation manner, step 206 may be specifically implemented in the following manner: the receiving device detects multiple reference signals simultaneously sent by the transmitting device and other transmitting devices by using receiving beams with different directions. Specifically, the receiving device sequentially uses the 1st to Kth beamforming vectors in the switched beam codebook W to simultaneously detect multiple reference signals sent by the sending device and other sending devices. Each receive beam lasts for one OFDM symbol, and the OFDM symbols correspond one-to-one with the OFDM symbols occupied by the reference signal sent by the transmitting device. Finally, the received signal corresponding to each reference signal in the multiple reference signals is obtained. For example, in scenario 1, the received signal corresponding to each reference signal may be a discrete time signal in the time domain. This mechanism makes it possible to use the MUSIC algorithm for AoA estimation under the analog beamforming architecture. Specifically, the traditional MUSIC requires multiple RF chains, and the computational complexity is reduced by using digital beamforming, which is completed at the baseband. In analog beamforming, the signals corresponding to multiple beamforming vectors can only be collected by beam time-division switching, and the AoA can be estimated by using these signals as input parameters of the traditional MUSIC algorithm.

相应的，在场景1中为了准确计算发送设备的信号到达角，接收设备首先将不同发送设备发送的每次参考信号所对应的接收信号转换到频域，在频域将不同发送设备发送的每次参考信号区分开来，分别计算每个发送设备的信号到达角。Correspondingly, in Scenario 1, in order to accurately calculate the signal arrival angle of the sending device, the receiving device first converts the received signal corresponding to each reference signal sent by different sending devices to the frequency domain, and in the frequency domain, converts each signal sent by different sending devices to the frequency domain. The secondary reference signals are distinguished, and the signal arrival angle of each transmitting device is calculated separately.

因此，作为一种可能的实现，本申请实施例中接收设备对多次接收信号执行数字信号处理以下方式实现：接收设备将多次接收信号从时域转换至频域。Therefore, as a possible implementation, in the embodiment of the present application, the receiving device performs digital signal processing on the multiple-time received signal to achieve the following manner: the receiving device converts the multiple-time received signal from the time domain to the frequency domain.

具体的，接收设备将同时接收到来自该发送设备的多次接收信号和来自其他发送设备的多次接收信号进行快速傅里叶逆变换(Inverse Fast Fourier Transform，IFFT)时频转换，通过子载波将对应于不同发送设备的接收信号区分开，每个发送设备的接收信号占用J个子载波，不同发送设备中每个发送设备对应一个K×J维的频域接收信号矩阵Y_K×J。Specifically, the receiving device performs an Inverse Fast Fourier Transform (IFFT) time-frequency conversion on the multiple received signals from the sending device and the multiple received signals from other sending devices at the same time. Distinguish received signals corresponding to different transmitting devices, each transmitting device occupies J subcarriers, and each transmitting device in different transmitting devices corresponds to a K×J-dimensional frequency domain receiving signal matrix Y_K×J .

为了降低计算复杂度，本申请实施例中可以对多次接收信号中满足要求的至少一次接收信号执行数字信号处理，得到多次接收信号对应的接收信号矩阵。In order to reduce the computational complexity, in this embodiment of the present application, digital signal processing may be performed on at least one received signal that meets the requirements among the multiple received signals, to obtain a received signal matrix corresponding to the multiple received signals.

作为本申请的一种可能的实现，本申请实施例中的步骤207具体可以通过以下方式实现：As a possible implementation of the present application, step 207 in this embodiment of the present application may be specifically implemented in the following manner:

接收设备根据多个接收波束的信号参数，从多个接收波束中确定至少一个接收波束。The receiving device determines at least one receive beam from the plurality of receive beams according to signal parameters of the plurality of receive beams.

接收设备根据至少一个接收波束，确定至少一个接收波束对应的至少一次接收信号。The receiving device determines, according to the at least one receiving beam, at least one received signal corresponding to the at least one receiving beam.

接收设备对至少一次接收信号执行数字信号处理，得到多次接收信号对应的接收信号矩阵。The receiving device performs digital signal processing on at least one received signal to obtain a received signal matrix corresponding to multiple received signals.

示例性的，对于一个发送设备来说，接收设备根据多个接收波束的信号参数，从多个接收波束中确定至少一个接收波束，可以通过以下方式实现：接收设备根据多个接收波束的信号参数从多个接收波束中选择信号参数满足要求的至少一个接收波束。例如，以信号参数为信号能量为例，接收设备根据多个接收波束的信号能量，从多个接收波束中选择信号能量大于或等于能量阈值的接收波束作为至少一个接收波束。Exemplarily, for a sending device, the receiving device determines at least one receiving beam from the multiple receiving beams according to the signal parameters of the multiple receiving beams, which can be implemented in the following manner: At least one receiving beam whose signal parameters meet the requirements is selected from the plurality of receiving beams. For example, taking the signal parameter as the signal energy as an example, the receiving device selects a receiving beam whose signal energy is greater than or equal to an energy threshold from the multiple receiving beams as at least one receiving beam according to the signal energy of the multiple receiving beams.

例如，接收设备从K个接收波束中选取B(B小于或等于K，且B大于或等于1)个接收信号能量大于或等于能量阈值的接收波束(可以简称为：有效接收波束)。该接收波束分别对应的波束赋形向量组成有效波束赋形矩阵

对应的频域接收信号形成一个B×J维的有效接收信号矩阵Y_B×J(即多次接收信号对应的接收信号矩阵)。其中，第B行第J列的元素代表第B个有效接收波束在第J个子载波上接收到的OFDM符号。For example, the receiving device selects B (B is less than or equal to K, and B is greater than or equal to 1) receiving beams with received signal energy greater than or equal to an energy threshold from K receiving beams (may be simply referred to as: effective receiving beams). The beamforming vectors corresponding to the receiving beams respectively form an effective beamforming matrix

The corresponding received signals in the frequency domain form a B×J-dimensional effective received signal matrix Y_B×J (that is, a received signal matrix corresponding to multiple received signals). The elements in the Bth row and the Jth column represent the OFDM symbols received by the Bth effective receiving beam on the Jth subcarrier.

应理解，本申请实施例中至少一个接收波束对应的至少一次接收信号指：该至少一个接收波束中每个接收波束上接收到的一次接收信号。It should be understood that the at least one received signal corresponding to at least one receive beam in this embodiment of the present application refers to: the one receive signal received on each receive beam in the at least one receive beam.

场景2)、发送设备和接收设备的阵列天线架构为采用模拟波束赋形架构，发送设备和接收设备采用载波侦听多路访问(Carrier Sense Multiple Access，CSMA)技术通信或时分多址(Time Division Multiple Acces，TDMA)技术通信。Scenario 2), the array antenna architecture of the transmitting device and the receiving device adopts an analog beamforming architecture, and the transmitting device and the receiving device use the carrier sense multiple access (Carrier Sense Multiple Access, CSMA) technology communication or Time Division Multiple Access (Time Division Multiple Access) Multiple Access, TDMA) technical communication.

在一种可能的实现方式中，步骤206具体可以通过下述方式具体实现：接收设备使用具有不同波束方向的接收波束对一个发送设备发送的多次参考信号进行检测。具体来说，接收设备顺次使用切换波束码本W中第1到第K个波束赋形向量来检测该发送设备发送的重复了K次的参考信号，每个接收波束内检测到M(M为大于或等于1的整数)个信号采样点，最终形成一个K×M维的接收信号采样点矩阵Y_K×M，作为多次接收信号。In a possible implementation manner, step 206 may be specifically implemented in the following manner: the receiving device uses receive beams with different beam directions to detect multiple reference signals sent by a transmitting device. Specifically, the receiving device sequentially uses the 1st to Kth beamforming vectors in the switched beam codebook W to detect the reference signal repeated K times sent by the transmitting device, and M(M) is detected in each receiving beam. is an integer greater than or equal to 1) signal sampling points, and finally a K×M-dimensional received signal sampling point matrix Y_K×M is formed as multiple received signals.

相应的，在场景2中接收设备可以直接利用时域采样信号进行信号到达角估计。Correspondingly, inscenario 2, the receiving device can directly use the time-domain sampled signal to estimate the angle of arrival of the signal.

作为本申请的一种可能的实现，本申请实施例中的步骤207具体可以通过以下方式实现：As a possible implementation of the present application, step 207 in this embodiment of the present application may be specifically implemented in the following manner:

接收设备根据多个接收波束的信号参数，从多个接收波束中确定至少一个接收波束。The receiving device determines at least one receive beam from the plurality of receive beams according to signal parameters of the plurality of receive beams.

接收设备根据至少一个接收波束，确定至少一个接收波束对应的至少一次接收信号。The receiving device determines, according to the at least one receiving beam, at least one received signal corresponding to the at least one receiving beam.

接收设备将至少一次接收信号对应的接收信号矩阵，作为多次接收信号对应的接收信号矩阵。The receiving device uses the received signal matrix corresponding to the at least one received signal as the received signal matrix corresponding to the multiple received signals.

例如，接收设备从K个接收波束中选取B个接收信号能量最大的接收波束作为有效波束，其对应的波束赋形向量组成有效波束赋形矩阵

对应的接收信号形成一个B×M维的有效接收信号矩阵Y_B×M，其中第B行第M列的元素代表第B个有效波束收到的第M个采样点。For example, the receiving device selects B receiving beams with the highest received signal energy from the K receiving beams as effective beams, and the corresponding beamforming vectors form an effective beamforming matrix

The corresponding received signals form a B×M-dimensional effective received signal matrix Y_B×M , wherein the elements of the B-th row and the M-th column represent the M-th sampling point received by the B-th effective beam.

在场景1和场景2中，接收设备依次切换所述一列或多列波束赋形向量中每列波束赋形向量，以调整所述每列波束赋形向量各自对应的接收波束的波束方向。In Scenario 1 andScenario 2, the receiving device sequentially switches each column of beamforming vectors in the one or more columns of beamforming vectors to adjust the beam direction of the receiving beam corresponding to each column of beamforming vectors.

场景3)、发送设备和接收设备的阵列天线架构为采用混合波束赋形架构，此时，发送设备和接收设备可以采用FDMA技术或OFDMA技术通信。也可以采用CSMA技术通信或TDMA技术通信。Scenario 3), the array antenna architecture of the transmitting device and the receiving device adopts a hybrid beamforming architecture. At this time, the transmitting device and the receiving device can communicate using the FDMA technology or the OFDMA technology. It is also possible to use CSMA technology communication or TDMA technology communication.

在一种可能的实现方式中，发送设备和接收设备采用FDMA技术或OFDMA技术通信时，场景3中步骤206具体可以通过下述方式具体实现方式可以参考场景1中的描述。区别在于，对于混合波束赋形架构，由于混合波束赋形架构具备同时实现多个接收波束的能力，假设能够同时形成的接收波束数量为I个，那么当I＞K时，该步骤只需消耗一个OFDM符号，当I＜K时，该步骤需要消耗

个OFDM符号，该OFDM符号与发送设备发送参考信号所占用的OFDM符号一一对应。混合波束赋形架构能够进一步降低波束训练开销。In a possible implementation manner, when the sending device and the receiving device communicate using the FDMA technology or the OFDMA technology, step 206 in scenario 3 may be specifically implemented in the following manner, and reference may be made to the description in scenario 1. The difference is that for the hybrid beamforming architecture, since the hybrid beamforming architecture has the ability to realize multiple receiving beams at the same time, assuming that the number of receiving beams that can be formed at the same time is I, then when I>K, this step only needs to consume One OFDM symbol, when I<K, this step needs to consume

OFDM symbols, the OFDM symbols are in one-to-one correspondence with the OFDM symbols occupied by the transmitting device to transmit the reference signal. The hybrid beamforming architecture can further reduce beam training overhead.

此外，发送设备和接收设备采用FDMA技术或OFDMA技术通信时，场景3中步骤207具体可以参考场景1中的描述。In addition, when the sending device and the receiving device communicate by using the FDMA technology or the OFDMA technology, the step 207 in the scenario 3 may refer to the description in the scenario 1 for details.

在另一种可能的实现方式中，发送设备和接收设备采用CSMA技术通信或TDMA技术通信时，场景3中步骤206具体可以通过下述方式具体实现方式可以参考场景2中的描述。In another possible implementation, when the sending device and the receiving device communicate using the CSMA technology or the TDMA technology, step 206 in scenario 3 can be specifically implemented in the following manner, and reference can be made to the description inscenario 2.

此外，在发送设备和接收设备采用CSMA技术通信或TDMA技术通信时，场景3中步骤207具体可以参考场景2中的描述，此处不再赘述。In addition, when the sending device and the receiving device communicate using the CSMA technology or the TDMA technology, the step 207 in the scenario 3 can refer to the description in thescenario 2 for details, and details are not repeated here.

应理解，在场景3中每列波束赋形向量除了对应一组移相器相移值之外，还可以对应一组数字波束赋形权重；所述接收设备依次切换所述一列或多列波束赋形向量中的至少一列波束赋形向量，以调整与所述至少一列波束赋形向量对应的接收波束的波束方向。It should be understood that in scenario 3, in addition to corresponding to a set of phase shifter phase shift values, each column of beamforming vectors may also correspond to a set of digital beamforming weights; the receiving device sequentially switches the one or more columns of beams at least one column of beamforming vectors in the beamforming vectors to adjust the beam direction of the receiving beam corresponding to the at least one column of beamforming vectors.

针对上述场景1-场景3，本申请实施例中的步骤209具体可以通过以下方式实现：For the above scenarios 1 to 3, step 209 in this embodiment of the present application may be specifically implemented in the following manner:

作为一种具体实现，本申请实施例中的S1可以通过以下方式实现：以目标角度范围为(θ_l,θ_u)为例，则接收设备可以按照一个固定的角度△θ将目标角度范围分为一个或多个待评估角度。例如，θ＝θ_l:△θ:θ_u。As a specific implementation, S1 in this embodiment of the present application may be implemented in the following manner: taking the target angle range as (θ_l , θ_u ) as an example, the receiving device may divide the target angle range into two parts according to a fixed angle Δθ is one or more angles to be evaluated. For example, θ=θ_l :Δθ:θ_u .

S2、接收设备根据所述波束映射矩阵，计算所述一个或多个待评估角度中每个待评估角度对应的评估指标。S2. The receiving device calculates, according to the beam mapping matrix, an evaluation index corresponding to each angle to be evaluated among the one or more angles to be evaluated.

其中，对于任意的一个待评估角度θ，该待评估角度θ对应的评估指标P(θ)的计算方法如下：所述接收设备根据公式

应理解，峰值评估指标即可以指一个或多个评估指标中评估指标最大的。It should be understood that the peak evaluation index may refer to the largest evaluation index among one or more evaluation indexes.

在一种可选的实现方式中，本申请实施例提供的方法还包括：接收设备根据所述多次接收信号对应的接收信号矩阵以及与待评估角度有关的系数，将所述接收信号矩阵映射成为波束映射矩阵；其中，所述待评估角度有关的系数

其中，a(θ)表示对应于待评估方向的阵列响应矢量，

where a(θ) represents the array response vector corresponding to the direction to be evaluated,

在一种可选的实现方式中，虚拟波束码本满足不同列向量之间相互正交。In an optional implementation manner, the virtual beam codebook satisfies that different column vectors are mutually orthogonal.

在一种可能的实现方式中，如果发送设备中具有预配置信息，该预配置信息至少包括：预存储的参考信号资源以及与该预存储的参考信号资源对应的参考信号的重复次数，则本申请实施例中的步骤204可以通过以下方式实现：发送设备根据预配置信息，确定参考信号资源和在参考信号资源发送的参考信号的重复次数。In a possible implementation manner, if the sending device has pre-configuration information, the pre-configuration information includes at least: pre-stored reference signal resources and the repetition times of the reference signals corresponding to the pre-stored reference signal resources, then this Step 204 in the embodiment of the application may be implemented in the following manner: the sending device determines the reference signal resource and the repetition times of the reference signal sent in the reference signal resource according to the pre-configured information.

在另一种可能的实施例中，如图6所示，本申请实施例提供的方法在步骤204之前还包括：In another possible embodiment, as shown in FIG. 6 , before step 204, the method provided by this embodiment of the present application further includes:

步骤202、接收设备向发送设备发送控制信令，该控制信令用于确定为发送设备配置的参考信号资源和在参考信号资源发送的参考信号的重复次数。Step 202: The receiving device sends control signaling to the sending device, where the control signaling is used to determine the reference signal resource configured for the sending device and the repetition times of the reference signal sent in the reference signal resource.

以接收设备为基站，发送设备为终端为例，则步骤202可以为下行控制信令(Downcontrol information，DCI)。该DCI用于确定为发送设备配置的参考信号资源和参考信号的重复次数。Taking the receiving device as the base station and the sending device as the terminal as an example, step 202 may be downlink control signaling (Downcontrol information, DCI). The DCI is used to determine the reference signal resource configured for the transmitting device and the repetition times of the reference signal.

具体的，接收设备向发送设备发送下行控制信道，该下行控制信道中携带DCI。例如，下行控制信道可以为物理下行控制信道(Physical Downlink Control Channel，PDCCH)。Specifically, the receiving device sends a downlink control channel to the transmitting device, and the downlink control channel carries the DCI. For example, the downlink control channel may be a physical downlink control channel (Physical Downlink Control Channel, PDCCH).

本申请实施例中接收设备可以为发送设备动态配置参考信号资源和参考信号的重复次数。或者接收设备也可以为发送设备半静态配置参考信号资源和参考信号的重复次数。其中，所谓接收设备为发送设备动态配置参考信号资源和参考信号的重复次数指：在每个波束训练周期内，接收设备为发送设备配置参考信号资源和参考信号的重复次数。所谓接收设备为发送设备半静态配置参考信号资源和参考信号的重复次数指：接收设备为发送设备配置的参考信号资源和参考信号的重复次数不仅适用于当前波束训练周期，也可以适用于下一个波束训练周期。In this embodiment of the present application, the receiving device may dynamically configure the reference signal resources and the repetition times of the reference signal for the transmitting device. Alternatively, the receiving device may also semi-statically configure the reference signal resources and the repetition times of the reference signal for the transmitting device. Wherein, the so-called reference signal resources and reference signal repetition times configured dynamically by the receiving device for the transmitting device refer to: in each beam training period, the receiving device configures the reference signal resources and the repetition times of the reference signal for the transmitting device. The so-called repetition times of reference signal resources and reference signals semi-statically configured by the receiving device for the transmitting device refer to: the reference signal resources and the repetition times of the reference signals configured by the receiving device for the transmitting device are not only applicable to the current beam training period, but also applicable to the next beam training period. Beam training period.

步骤203、发送设备接收来自接收设备的控制信令。Step 203: The sending device receives the control signaling from the receiving device.

在另一种可能的实现方式中，本申请实施例中的步骤204具体可以通过以下方式实现：发送设备根据控制信令确定参考信号资源和参考信号的重复次数。In another possible implementation manner, step 204 in this embodiment of the present application may be specifically implemented in the following manner: the sending device determines the reference signal resource and the repetition times of the reference signal according to the control signaling.

需要说明的是，如果发送设备根据预配置信息确定参考信号资源和参考信号的重复次数，则步骤202和步骤203可以省略。也即202和步骤203为可选的步骤。当然，如果发送设备根据预配置信息自主确定参考信号资源和参考信号的重复次数之后，发送设备还需要向接收设备发送设备自主确定的参考信号资源的信息和重复次数，这样便于接收设备确定在哪个参考信号资源接收发送设备重复发送的多次参考信号。It should be noted that, if the sending device determines the reference signal resource and the repetition times of the reference signal according to the pre-configured information, steps 202 and 203 may be omitted. That is, step 202 and step 203 are optional steps. Of course, if the sending device autonomously determines the reference signal resources and the number of repetitions of the reference signal according to the preconfigured information, the sending device also needs to send the information about the reference signal resources and the number of repetitions of the reference signal resources independently determined by the device to the receiving device, so that the receiving device can determine where The reference signal resource receives the reference signals repeatedly sent by the sending device.

应理解，在发送设备可以自主确定参考信号资源和重复次数的情况下，如果接收设备通过步骤202为发送设备配置参考信号资源和重复次数，则发送设备以接收设备配置的参考信号资源和重复次数执行步骤204和步骤205。It should be understood that in the case where the sending device can independently determine the reference signal resources and the number of repetitions, if the receiving device configures the reference signal resources and the number of repetitions for the sending device through step 202, the sending device uses the reference signal resources and the number of repetitions configured by the receiving device. Steps 204 and 205 are performed.

由于发送设备和接收设备之间所采用的通信技术不同，接收设备为发送设备配置的参考信号资源存在差异，下述将分别介绍：Due to the different communication technologies used between the sending device and the receiving device, the reference signal resources configured by the receiving device for the sending device are different, which will be introduced separately as follows:

示例1)、发送设备和接收设备采用频分多址(frequency division multipleaccess，FDMA)技术或正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)技术通信。Example 1) The transmitting device and the receiving device communicate using a frequency division multiple access (frequency division multiple access, FDMA) technology or an orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA) technology.

在示例1)中接收设备为该发送设备配置的参考信号资源与接收设备为其他发送设备配置的参考信号资源在频域正交。也即接收设备为包括该发送设备在内的多个发送设备分别配置时频资源，不同的发送设备在频域上占用不同的子载波或载波，不同的发送设备在时域上可以占用相同的OFDM符号或FDM符号。In Example 1), the reference signal resources configured by the receiving device for the sending device are orthogonal to the reference signal resources configured by the receiving device for other sending devices in the frequency domain. That is, the receiving device configures time-frequency resources for multiple transmitting devices including the transmitting device. Different transmitting devices occupy different sub-carriers or carriers in the frequency domain, and different transmitting devices can occupy the same sub-carriers or carriers in the time domain. OFDM symbols or FDM symbols.

在示例1)中多次参考信号中每次占用一个OFDM符号、J个子载波。In Example 1), the multiple reference signals occupy one OFDM symbol and J subcarriers each time.

也即如果发送设备和接收设备采用OFDMA技术或FDMA技术通信时，接收设备可以为多个不同的发送设备配置在频域正交的参考信号资源，这样便于多个不同的发送设备同时在各自的参考信号资源上向接收设备发送多次参考信号。从而可以使得接收设备对多个不同的发送设备并行或同时进行波束训练，互不冲突。由于不同发送设备可以在被分配的时频资源上重复发送参考信号，因此，多个发送设备可以并行进行波束训练最终实现既快速又准确的波束训练性能。That is, if the sending device and the receiving device communicate using OFDMA technology or FDMA technology, the receiving device can configure reference signal resources orthogonal to the frequency domain for multiple different sending devices, which is convenient for multiple different sending devices to communicate in their respective The reference signal is sent to the receiving device multiple times on the reference signal resource. Therefore, the receiving device can perform beam training on multiple different transmitting devices in parallel or at the same time without conflicting with each other. Since different transmitting devices can repeatedly transmit reference signals on the allocated time-frequency resources, multiple transmitting devices can perform beam training in parallel, and finally achieve fast and accurate beam training performance.

此外，接收设备为不同发送设备配置的重复次数可以相同，也可以不相同。In addition, the number of repetitions configured by the receiving device for different sending devices may be the same or different.

例如，接收设备为发送设备10配置的参考信号资源位于频域资源1、接收设备为发送设备20配置的参考信号资源位于频域资源2。接收设备为发送设备30配置的参考信号资源位于频域资源3。其中，频域资源1、频域资源2、频域资源3在频域正交。For example, the reference signal resource configured by the receiving device for the sendingdevice 10 is located in the frequency domain resource 1, and the reference signal resource configured by the receiving device for the transmittingdevice 20 is located in thefrequency domain resource 2. The reference signal resource configured by the receiving device for the sendingdevice 30 is located in the frequency domain resource 3 . Among them, the frequency domain resource 1, thefrequency domain resource 2, and the frequency domain resource 3 are orthogonal in the frequency domain.

需要说明的是，不同的发送设备同时向接收设备发送一次参考信号时，所使用的参考信号资源不同。例如，第一次传输时，发送设备1使用子载波1、子载波2以及子载波3发送第一次参考信号，发送设备2使用子载波4、和子载波5发送第一次参考信号。但是对于不同次传输的参考信号，其所占用的参考信号资源可以相同。例如，第一次传输时，发送设备1使用子载波1、子载波2以及子载波3发送第一次参考信号，发送设备2使用子载波4、和子载波5发送第一次参考信号。第二次传输时，发送设备1使用子载波4、和子载波5发送第二次参考信号。发送设备2使用子载波1、子载波2发送第二次参考信号。It should be noted that when different transmitting devices simultaneously transmit a reference signal to a receiving device once, the used reference signal resources are different. For example, in the first transmission, sending device 1 uses subcarrier 1,subcarrier 2, and subcarrier 3 to send the first reference signal, and sendingdevice 2 uses subcarrier 4 and subcarrier 5 to send the first reference signal. However, for reference signals transmitted at different times, the occupied reference signal resources may be the same. For example, in the first transmission, sending device 1 uses subcarrier 1,subcarrier 2, and subcarrier 3 to send the first reference signal, and sendingdevice 2 uses subcarrier 4 and subcarrier 5 to send the first reference signal. During the second transmission, the sending device 1 uses the subcarrier 4 and the subcarrier 5 to send the reference signal for the second time. The sendingdevice 2 uses the subcarrier 1 and thesubcarrier 2 to send the second reference signal.

示例2)、发送设备和接收设备采用载波侦听多路访问(Carrier Sense MultipleAccess，CSMA)技术通信或时分多址(Time Division Multiple Acces，TDMA)技术通信。Example 2) The sending device and the receiving device use the carrier sense multiple access (Carrier Sense Multiple Access, CSMA) technology to communicate or the time division multiple access (Time Division Multiple Access, TDMA) technology to communicate.

在示例2)中接收设备为该发送设备配置的参考信号资源的时域与接收设备为其他发送设备配置的参考信号资源的时域不同。也即接收设备为不同发送设备配置的参考信号资源被分配到不同的时间区间上，这样可以使得多个不同的发送设备在不同的时间区间内利用各自配置的参考信号资源向接收设备发送参考信号。从而多个不同的发送设备可以串行进行波束训练，互不冲突。应理解，在CSMA或TDMA技术中，每个时刻，只有一个发送设备占用信道，即占用所有的频域载波。In Example 2), the time domain of the reference signal resources configured by the receiving device for the transmitting device is different from the time domain of the reference signal resources configured by the receiving device for other transmitting devices. That is, the reference signal resources configured by the receiving device for different sending devices are allocated to different time intervals, so that multiple different sending devices can use their configured reference signal resources to send reference signals to the receiving device in different time intervals. . Therefore, multiple different transmitting devices can perform beam training in series without conflicting with each other. It should be understood that in the CSMA or TDMA technology, at each moment, only one transmitting device occupies the channel, that is, occupies all the frequency domain carriers.

例如，接收设备为发送设备1配置的参考信号资源位于时域1，接收设备为发送设备2配置的参考信号资源位于时域2。For example, the reference signal resources configured by the receiving device for the transmitting device 1 are located in the time domain 1, and the reference signal resources configured by the receiving device for the transmittingdevice 2 are located in thetime domain 2.

在示例2)中接收设备为不同发送设备配置的重复次数可以相同，也可以不相同。In Example 2), the number of repetitions configured by the receiving device for different sending devices may be the same or different.

需要说明的是，在示例1)和示例2)中发送设备和接收设备的阵列天线架构为模拟波束赋形架构，且接收设备为发送设备配置的重复次数为K表示波束赋形向量的个数。K为大于或等于1的整数。It should be noted that, in Example 1) and Example 2), the array antenna architecture of the transmitting device and the receiving device is an analog beamforming architecture, and the number of repetitions configured by the receiving device for the transmitting device is K indicating the number of beamforming vectors. . K is an integer greater than or equal to 1.

示例3)、发送设备和接收设备的阵列天线架构为混合波束赋形架构。当阵列天线架构为模拟波束赋形架构时，系统多址方式考虑两种情况：OFDMA或(FDMA)、CSMA(或TDMA)，这两种多址方式的区别在于多个发送设备是否可以同时进行AoA估计。同理，当阵列天线架构为混合波束赋形架构时，系统多址方式存在同样的两种情况。示例3)仅结合OFDMA系统进行说明。Example 3), the array antenna architecture of the transmitting device and the receiving device is a hybrid beamforming architecture. When the array antenna architecture is an analog beamforming architecture, the system multiple access method considers two situations: OFDMA or (FDMA), CSMA (or TDMA). The difference between these two multiple access methods is whether multiple transmitting devices can perform simultaneous AoA estimates. Similarly, when the array antenna architecture is a hybrid beamforming architecture, the same two situations exist in the system multiple access method. Example 3) is only described in conjunction with the OFDMA system.

混合波束赋形架构能够同时形成多个不同指向的波束，进一步降低波束切换的开销，该多个不同指向的波束数目用I表示。不同终端利用不同的子载波同时发送上行参考信号，从而能够并行进行波束训练，互不冲突。每个UE发送上行参考信号的时频资源以及该参考信号的生效次数由BS通过下行控制信令进行配置。The hybrid beamforming architecture can simultaneously form multiple beams with different directions, further reducing the overhead of beam switching. The number of the multiple beams with different directions is denoted by I. Different terminals use different subcarriers to send uplink reference signals at the same time, so that beam training can be performed in parallel without conflicting with each other. The time-frequency resource for sending the uplink reference signal by each UE and the number of times the reference signal is valid are configured by the BS through downlink control signaling.

需要说明的是，发送设备和接收设备的阵列天线架构为混合波束赋形架构时，为发送设备配置的参考信号资源可以与示例1)一样，即多个不同的发送设备的参考信号资源在频域正交。当然，在发送设备和接收设备的阵列天线架构为混合波束赋形架构时，为发送设备配置的参考信号资源可以与示例2)一样，即多个不同的发送设备的参考信号资源具有不同的时域。It should be noted that when the array antenna architecture of the transmitting device and the receiving device is a hybrid beamforming architecture, the reference signal resources configured for the transmitting device may be the same as in Example 1), that is, the reference signal resources of multiple different transmitting devices are in frequency Domain Orthogonal. Of course, when the array antenna architecture of the transmitting device and the receiving device is a hybrid beamforming architecture, the reference signal resources configured for the transmitting device may be the same as in Example 2), that is, the reference signal resources of multiple different transmitting devices have different timings. area.

具体示例可以示例1)中的描述，但是与示例1)的区别在于：在示例3)中每次参考信号占用一个OFDM符号、J个子载波，相同的参考信号在时间轴上重复

次，即重复次数为

其中I表示混合波束赋形能够同时形成的波束数量。A specific example can be described in Example 1), but the difference from Example 1) is that in Example 3) each reference signal occupies one OFDM symbol and J subcarriers, and the same reference signal is repeated on the time axis

times, that is, the number of repetitions is

where I represents the number of beams that can be simultaneously formed by hybrid beamforming.

在一种可能的实施例中，如图6所示，本申请实施例提供的方法还包括：In a possible embodiment, as shown in FIG. 6 , the method provided by the embodiment of the present application further includes:

步骤210、接收设备根据所述信号到达角，调整所述接入设备与所述发送设备之间的接收波束方向。Step 210: The receiving device adjusts the direction of the receiving beam between the access device and the sending device according to the angle of arrival of the signal.

即在确定信号到达角之后，接收设备使用信号到达角指导后续接入设备与所述发送设备进行数据传输的波束指向，即波束对准。具体的，在得到信号到达角之后，根据信号传输路径的互易性，将波束赋形方向配置为估计出的信号到达角方向，即可实现波束对准，然后进行数据传输。如果检测出了多个信号到达角方向，可以结合信号能量，进一步确定一个或几个最优信号到达角方向作为波束指向。That is, after the angle of arrival of the signal is determined, the receiving device uses the angle of arrival of the signal to guide the beam orientation for data transmission between the subsequent access device and the sending device, that is, beam alignment. Specifically, after obtaining the angle of arrival of the signal, according to the reciprocity of the signal transmission path, the beamforming direction is configured as the direction of the estimated angle of arrival of the signal, so as to realize beam alignment and then perform data transmission. If multiple signal arrival angle directions are detected, one or several optimal signal arrival angle directions can be further determined as beam pointing by combining the signal energy.
