As shown in Figure 1, the beam weight adjustment method includes:

Step 101: Obtain the initial beam weight matrix of the multi-transceiver channel antenna in the first polarization direction.

In this application, the multi-transceiver channel antenna may be a dual-polarized antenna, that is, it includes two polarization directions, where each polarization direction has a corresponding initial beam weight matrix.

In this application, the initial beam weight matrix of the multi-transceiver channel antenna in the first polarization direction can be obtained. Among them, the initial beam weight matrix refers to the initial beam weight of the antenna, and the number of weights in the initial beam weight matrix is related to the number of transceiver channels of the antenna.

Taking the 64TR (64Transiver Resever, 64 transceiver channels) antenna as an example, the topology of the 64TR antenna is shown in Figure 2, where Ant represents the antenna, and Ant0, Ant1,..., Ant31 represent the numbers of the dual-polarized antennas. Assume that the initial beam weight matrix in a certain polarization direction of the 64TR (4 rows and 8 columns) antenna SSB (Synchronization Signal and Physical Boardcast Channel block, synchronization signal and physical broadcast channel block) beam is:

Among them, θ represents the horizontal beam direction, represents the vertical beam direction, d represents the array element spacing, λ represents the wavelength, and j represents the imaginary indicator. It can be seen that the initial beam weight matrix of the 64TR antenna in a certain polarization direction is a 4*8 matrix, including a total of 32 weights.

Step 102: Determine the weight to be interfered with in the first direction from the initial beam weight matrix.

In this application, the first direction may be a vertical direction or a horizontal direction. For example, if the first direction is the vertical direction, a certain column of weights in the vertical direction can be selected as the weights to be interfered with in the initialization beam weight matrix.

Taking the initial beam weight matrix of the above-mentioned 64TR antenna SSB beam in a certain polarization direction as an example, the weights in the first column of the above-mentioned W can be as the weight to be interfered with.

Step 103: Determine the target phase value corresponding to the weight value to be interfered from among multiple candidate phase values.

In this application, multiple candidate phase values can be selected from a preset angle range, for example, from 0 to 360 degrees, 0 degrees, 30 degrees, 60 degrees, ..., 360 degrees are used as candidate phase values, and from Among multiple candidate phase values, the target phase value corresponding to the weight value to be interfered is determined. Among them, the target phase value is used to interfere with the weight value to be interfered.

When determining the target phase value, one can be randomly selected as the target phase value from multiple candidate phase values, or the target phase value can be determined based on the null filling effect of each candidate phase value on the interference weight. Among them, the greater the difference between the gain after filling the zero trap position and the gain before filling, the better the zero trap filling effect is.

Step 104: Determine the target beam weight matrix based on the target phase value, the weight value to be interfered with, and the initial beam weight matrix.

After determining the target phase value, the target phase value can be used to perform interference processing on the weight to be interfered to obtain the weight after interference.

When using the target phase value to perform interference processing on the weight to be interfered with, the target phase value can be used to interfere with the weight of a certain antenna in the weight to be interfered with to obtain the weight after interference. Thus, the phase of one of the radiation points is perturbed, If the power of the radiating point is not changed, the gain will increase at the beam synthesis null. However, for the main beam, only the weight of the local antenna is changed, which will not affect the main beam, achieving power-free null filling.

For example, the target phase value is Treat interference weight The first weight value 1 in the phase interference is obtained Alternatively, one of the other three weights can also be interfered with, which is not limited in this application.

After obtaining the post-interference weights, a tensor product can be performed between the post-interference weights and the weights in the second direction in the initial beam weight matrix to obtain the target beam weight matrix. Among them, the second direction is perpendicular to the first direction. If the first direction is the vertical direction and the second direction is the horizontal direction, the tensor product refers to the cross product of the column vector and the row vector; if the first direction is the horizontal direction, the tensor product The second direction is the vertical direction, and the tensor product refers to the cross-multiplication of the row vector and the column vector; the size of the target beam weight matrix is the same as the size of the initial beam weight matrix.

For example, if the first direction is the vertical direction and the second direction is the horizontal direction, a certain column weight in the initial beam weight matrix can be used as the weight to be interfered, and the weight of a certain antenna in the weight to be interfered can be phase interfered to obtain After interference, the weight after interference is then tensor producted or cross-multiplied with a certain row weight in the initial beam weight matrix to obtain the target beam weight matrix, thereby filling the vertical dimension zero trap of the beam. .

If the first direction is the horizontal direction and the second direction is the vertical direction, a certain row weight in the initial beam weight matrix can be used as the weight to be interfered, and the weight of a certain antenna in the weight to be interfered can be phase interfered to obtain the interference Then, the tensor product, that is, cross-multiplication, is performed between the post-interference weight and a certain column weight in the initial beam weight matrix to obtain the target beam weight matrix, thereby filling the beam horizontal dimension zero notch.

Step 105: Adjust the initial beam weight matrix in the first polarization direction to the target beam weight matrix.

After the target beam weight matrix is determined, the initial beam weight matrix in the first polarization direction can be adjusted to the target beam weight matrix, that is, the initial beam weight matrix is updated to the target beam weight matrix. The base station can then transmit beams based on the target beam weight matrix.

In the embodiment of the present application, the initial beam weight matrix of the multi-transceiver channel antenna in the first polarization direction is obtained; the weight to be interfered in the first direction is determined from the initial beam weight matrix; and the weight to be interfered in the first direction is determined from multiple candidate phases. Among the values, determine the target phase value corresponding to the weight to be interfered; determine the target beam weight matrix according to the target phase value, the weight to be interfered and the initial beam weight matrix; convert the initial beam weight in the first polarization direction The matrix is adjusted to the target beam weight matrix. Therefore, by determining the target beam weight matrix based on the weight to be interfered determined from the initial beam weight matrix and the target phase value determined from multiple candidate phase values, compared with the beam based on adaptive optimization The optimized zero-sag filling method has a simple implementation algorithm and saves calculation time.

Figure 3 is a schematic flowchart of a beam weight adjustment method provided by an embodiment of the present application.

As shown in Figure 3, the beam weight adjustment method includes:

Step 301: Obtain the initial beam weight matrix of the multi-transceiver channel antenna in the first polarization direction.

Step 302: Determine the weight to be interfered with in the first direction from the initial beam weight matrix.

In this application, steps 301 to 302 are similar to those described in the above embodiments, so they will not be described again here.

Step 303: Use each candidate phase value among the plurality of candidate phase values to perform interference processing on the weight to be interfered to determine the post-interference weight corresponding to each candidate phase value.

In this application, each candidate phase value can be used to perform interference processing on the weight to be interfered to obtain a weight after interference.

For example, multiple candidate phase values include Use each candidate phase value to treat the interference weight The first weight value 1 in is subjected to phase interference, and we get

Step 304: Determine a target phase value from multiple candidate phase values based on the weight to be interfered and the post-interference weight corresponding to each candidate phase value.

As a possible implementation method, the first beam gain information of the weight to be interfered can be obtained based on the weight to be interfered, and the interference corresponding to each candidate phase value can be obtained based on the post-interference weight corresponding to each candidate phase value. The second beam gain information corresponding to the subsequent weight value. The beam gain information includes the gains of beams at different angles.

Afterwards, the first beam gain information and the second beam gain information can be compared to determine the null filling information and beam distortion information corresponding to each candidate phase value, and then based on the null filling information corresponding to the multiple candidate phase values respectively information and beam distortion information to determine the target phase value from multiple candidate phase values.

Among them, the null filling information is used to indicate the null filling effect of the beam. The null filling information can include the degree of improvement of the beam gain at each null position after the interference weight is interfered; the beam distortion information is used to indicate the interference weight. The degree of distortion of the beam before and after the value interference, and the beam distortion information can be based on the degree of consistency of the changing trend of the beam shape before and after the interference with the interference weight.

In practical applications, although the null filling effect is good, the degree of beam distortion may be serious. Therefore, in this application, when determining the target phase value based on the null filling information and the beam distortion information, the null filling information can be used and the weight of the beam distortion information to determine the target phase value. Among them, the weights of the null filling information and the beam distortion information can be set according to actual needs. For example, if the weight corresponding to the null filling information is relatively large, then when determining the target phase value, you can focus on selecting the candidate phase value with good null filling effect as the target candidate phase value.

Therefore, the null filling information and the beam gain information can be determined based on the beam gain information before and after the interference weight is interfered by each candidate phase value, and based on the null filling information and the beam gain information, the null filling information and the beam gain information can be determined from multiple candidate phase values. Output the phase value that can balance the null filling effect and the degree of beam distortion.

As another possible implementation, determine the first beam gain information corresponding to the weight to be interfered and the second beam gain information corresponding to the interfered weight corresponding to each candidate phase value. According to the first beam gain information and The second beam gain information, output and display the beam gain comparison diagram between the interfered weight corresponding to each candidate phase value and the weight to be interfered, where the abscissa in the beam gain comparison diagram can be the beam angle, and the ordinate It can be a gain. Then, the user can determine the null filling effect and beam distortion effect corresponding to each candidate phase value based on the beam gain comparison chart corresponding to each candidate phase value, thereby determining the required target phase value from multiple candidate phase values. When the phase value input by the user is obtained, the phase value input by the user can be determined as the target phase value, where the phase value input by the user is one of multiple candidate phase values.

Among them, the user inputting the phase value can be that the user inputs the phase value in the phase value input box of the display interface, or the display interface can display a list of candidate phase values, and the user selects a phase value from the list of candidate phase values. This application does not do this. limited. For example, Figure 4 and Figure 5 respectively show the beam gain comparison diagram of the vertical beam under two different candidate phase values before and after the interference weight is interfered. The abscissa is the angle and the ordinate is the gain. , the dotted line represents the original beam (that is, the beam corresponding to the weight to be interfered), and the solid line represents the null filling beam (that is, the beam corresponding to the weight after interference). It can be seen that the null filling effect of Figure 5 is better than that of Figure 4 Good, but the degree of beam distortion in Figure 4 is smaller than that in Figure 5. The candidate phase value used in Figure 4 can be used as the target phase value.

Therefore, by displaying the beam gain comparison diagram before and after the to-be-interferenced weight value is interfered by each candidate phase value, the user can determine the target phase value as needed, which can meet the user's personalized needs.

Step 305: Determine the target beam weight matrix based on the target phase value, the weight value to be interfered with, and the initial beam weight matrix.

Step 306: Adjust the initial beam weight matrix in the first polarization direction to the target beam weight matrix.

In this application, steps 305 to 306 are similar to those recorded in the above embodiments, so they will not be described again here.

In the embodiment of the present application, when determining the target phase value from multiple candidate phase values based on the weight to be interfered and the post-interference weight corresponding to each candidate phase value, each of the multiple candidate phase values can be used. candidate phase values, perform interference processing on the weights to be interfered with to determine the post-interference weights corresponding to each candidate phase value, and based on the weights to be interfered and the post-interference weights corresponding to each candidate phase value, from multiple The target phase value is determined from the candidate phase values. Therefore, the target phase value is determined from multiple candidate phase values according to the weight value before and after interference with the to-be-interferenced weight value corresponding to each candidate phase value, thereby improving the beam null filling effect.

Step 604: Obtain the beam pointing deviation angle corresponding to each candidate phase value.

Since the null-filled beam may have a beam pointing deviation, in this application, the weight to be interfered can be determined The corresponding first beam information, and the second beam information corresponding to the interfered weight value corresponding to each candidate phase value, compare the first beam information and the second beam information to determine the value before and after the interference weight value is interfered. Beam pointing deviation angle. The beam pointing deviation angle may refer to the deviation angle between the beam pointing corresponding to the weight after interference and the beam pointing corresponding to the weight to be interfered.

For example, the angle of the maximum gain position on the beam can be determined based on the first beam information, and the angle of the maximum gain position on the beam can be determined based on the second beam information. The difference between these two angles can be used as the beam pointing deviation angle.

Step 605: Modify the post-interference weight according to the beam pointing deviation angle to obtain the corrected weight corresponding to each candidate phase value.

In this application, the beam pointing deviation angle corresponding to each candidate phase value can be used to modify the weight value after interference to obtain the modified weight value corresponding to each candidate phase value.

For example, the initial beam weight matrix in the first polarization direction is as W above, and the first column weight of W will be As the weight to be interfered, the target phase value is The beam pointing deviation angle is use Perform interference processing on the first weight among the weights to be interfered to obtain the weight after interference. use To correct w ₁ , the correction method is: in Represents the corrected weight.

Step 606: Determine a target phase value from multiple candidate phase values based on the weight value to be interfered with and the corrected weight value corresponding to each candidate phase value.

In this application, the target phase value can be determined based on the beam information corresponding to the weight to be interfered and the beam information corresponding to the corrected weight, which is the same as the weight after interference corresponding to the weight to be interfered and each candidate phase value. , the method of determining the target phase value is similar, so it will not be described again here.

The corresponding corrected weight.

For example, the target phase value is The beam pointing deviation angle is use Perform interference processing on the first weight among the to-be-interferenced weights w determined from the above-mentioned initial beam weight matrix W to obtain the post-interference weight. use To correct w, the correction method is:

Step 609: Determine the target beam weight matrix based on the corrected weight corresponding to the target phase value and the weight in the second direction in the initial beam weight matrix.
