[0002] The present application relates to the field of communication technologies, and in particular to a beam weight adjustment method, an apparatus, an access network device, a program product and a storage medium. [Background technology]

[0003] In 5G NR (New Radio), the introduction of ultra-large-scale antennas greatly improves spectrum efficiency and energy efficiency, and is the core key technology of 5G NR. With the introduction of more antennas, the radiation beam of the NR base station has higher gain, but it brings the problem that the beam gain is low at some angles, that is, multiple radiation becomes zero, and the beam becomes a cavity that is locally covered.

[0004] In the related art, beam optimization is mainly based on adaptive optimization algorithms, such as genetic algorithms, particle swarm algorithms, etc., and its basic idea is to randomly generate N sets of beam weight values ​​based on the desired target beam shape, obtain the corresponding beam shape based on the beam synthesis formula, compare the target beam shape with the beam shape corresponding to the random weight values, reserve some relatively better weight values, and then regenerate the N sets of beam weight values ​​based on a certain criterion, and further compare the above beams, and finally select a set of better weight values. However, this algorithm has high complexity and requires a long calculation time. Summary of the Invention [Problem to be solved by the invention]

[0034] As shown in FIG. 1, this beam weight adjustment method includes the following steps 101 to 105.

[0035] Step 101, obtain an initial beam weight matrix in a first polarization direction of a multi-transmit / receive channel antenna.

[0036] In this application, the multi-transmit / receive channel antenna may be a two-polarized antenna, ie, includes two polarization directions, where each polarization direction has a corresponding initial beam weight value matrix.

[0037] In this application, an initial beam weight value matrix of a first polarization direction of a multi-transmitting and receiving channel antenna can be obtained, where the initial beam weight value matrix refers to the weight value of an initial beam of the antenna, and the number of weight values ​​in the initial beam weight value matrix is ​​related to the number of transmitting and receiving channels of the antenna.

[0038] Taking 64 TR (64 Transiver Receiver) antenna as an example, the topology of 64 TR antenna is shown in Figure 2, where Ant represents an antenna, and Ant0, Ant1, ..., Ant31 represent the numbers for the two-polarized antenna. The initial beam weight matrix of a 64 TR (4 rows, 8 columns) antenna SSB (Synchronization Signal and Physical Broadcast Channel block) beam in a certain polarization direction is assumed as follows:

number

[0039] Here, θ represents the horizontal beam direction, φ represents the vertical beam direction, d represents the array spacing, λ represents the wavelength, and j represents the imaginary indicator. It can be seen that the initial beam weight value matrix for a polarization direction of the 64 TR antenna is a 4 × 8 matrix containing a total of 32 weight values.

[0040] Step 102: Determine a weight value of an interference target in a first direction from an initial beam weight value matrix.

[0041] In the present application, the first direction may be a vertical direction or a horizontal direction. For example, taking the first direction as an example of a vertical direction, a weight value in the vertical direction may be selected as the weight value of the interference target from the initialization beam weight value matrix.

[0042] Taking the initial beam weight matrix of the 64 TR antenna SSB beam in a certain polarization direction as an example, the first column weight value in w

[0043] Step 103: determining a target phase value corresponding to the weight value of the interference target from among a plurality of candidate phase values.

[0044] In the present application, a plurality of candidate phase values ​​can be selected from within a preset angle range, for example, 0 degrees, 30 degrees, 60 degrees, ..., 360 degrees are set as candidate phase values ​​within a range of 0 to 360 degrees, and a target phase value corresponding to the weight value of the interference target is determined from the plurality of candidate phase values. Here, the target phase value is used to interfere with the weight value of the interference target.

[0045] When determining the target phase value, one of multiple candidate phase values ​​may be randomly selected as the target phase value, or the target phase value may be determined based on the null-filling effect of each candidate phase value on the weight value of the interference target, where the larger the difference between the gain after filling the null position and before filling, the better the null-filling effect.

[0046] Step 104: determining a target beam weight matrix based on the target phase value, the weight value of the interferent, and the initial beam weight matrix.

[0047] After the target phase value is determined, the target phase value can be used to perform interference processing on the weight value of the interfered object to obtain the weight value after interference.

[0048] When using the target phase value to perform interference processing on the weight value of the interference target, the target phase value can be used to interfere with the weight value of a certain antenna among the weight values ​​of the interference target to obtain the weight value after interference. In this way, if the position of one of the radiation points is perturbed and the power of the radiation point is not changed, the phenomenon of gain lift occurs in the beam synthesis null, while only the weight value of the local antenna is changed for the main beam, so that the main beam is not affected and null filling without power loss is realized.

[0049] For example, the target phase value is Φ0 and the interference weight value is

number

[0050] After obtaining the post-interference weight values, the post-interference weight values ​​and the weight values ​​of the second direction in the initial beam weight value matrix can be tensor-producted to obtain a target beam weight value matrix, where the second direction is perpendicular to the first direction, the first direction is vertical, and the second direction is horizontal, the tensor product refers to squaring the column vector and the row vector, and when the first direction is horizontal and the second direction is vertical, the tensor product refers to squaring the row vector and the column vector, and the magnitude of the target beam weight value matrix is ​​the same as that of the initial beam weight value matrix.

[0051] For example, the first direction is vertical and the second direction is horizontal, and the weight values ​​of a certain column in the initial beam weight value matrix can be the weight values ​​of the interference target, and phase interference is performed on the weight values ​​of a certain antenna among the weight values ​​of the interference target to obtain the weight values ​​after interference, and then the weight values ​​after interference and the weight values ​​of a certain row in the initial beam weight value matrix are tensor-producted, i.e., squared, to obtain the target beam weight value matrix, thereby realizing filling the beam vertical dimension null.

[0052] When the first direction is horizontal and the second direction is vertical, the weight value of a certain row in the initial beam weight value matrix can be the weight value of the interfering object, and phase interference is performed on the weight value of a certain antenna among the weight values ​​of the interfering object to obtain the weight value after interference, and then the weight value after interference and the weight value of a certain column in the initial beam weight value matrix are tensor-producted, i.e., squared, to obtain the target beam weight value matrix, thereby realizing filling the beam horizontal dimension null.

[0053] Step 105, adjust the initial beam weight value matrix of the first polarization direction to the target beam weight value matrix.

[0054] After determining the target beam weight value matrix, the initial beam weight value matrix of the first polarization direction can be adjusted to the target beam weight value matrix, i.e., the initial beam weight value matrix can be updated to the target beam weight value matrix. Then, the base station can transmit a beam based on the target beam weight value matrix.

[0055] In an embodiment of the present application, an initial beam weight matrix in a first polarization direction of a multi-transmission channel antenna is obtained, a weight value of an interference object in the first direction is determined from the initial beam weight matrix, a target phase value corresponding to the weight value of the interference object is determined from a plurality of candidate phase values, a target beam weight matrix is ​​determined based on the target phase value, the weight value of the interference object, and the initial beam weight matrix, and the initial beam weight matrix in the first polarization direction is adjusted to the target beam weight matrix. Thus, by determining the target beam weight matrix based on the weight value of the interference object determined from the initial beam weight matrix and the target phase value determined from a plurality of candidate phase values, a simpler algorithm and less computation time are realized compared to the null-filling method of beam optimization based on adaptive optimization.

[0056] FIG. 3 is a schematic flowchart of a beam weight adjustment method provided by an embodiment of the present application.

[0057] As shown in FIG. 3, this beam weight adjustment method includes the following steps 301 to 306.

[0058] Step 301, obtain an initial beam weight matrix in a first polarization direction of a multi-transmit / receive channel antenna.

[0059] Step 302: Determine a weight value of an interference target in a first direction from an initial beam weight value matrix.

[0060] In the present application, steps 301 and 302 are similar to those described in the above embodiment, and therefore a description thereof will be omitted here.

[0061] Step 303: Using each candidate phase value among the plurality of candidate phase values, an interference process is performed on the weight value of the interfered object to determine a post-interference weight value corresponding to each candidate phase value.

[0062] In this application, each candidate phase value can be used to perform interference processing on the interfered weight values ​​to obtain one interfered weight value.

[0063] For example, multiple candidate phase values ​​are Φ1, Φ2, ..., Φ n and the weight value of the interference target is calculated using each candidate phase value.

number

[0064] Step 304: determining a target phase value from the plurality of candidate phase values ​​based on the interference weight value and the post-interference weight value corresponding to each candidate phase value.

[0065] As a possible implementation, a first beam gain information of the weight value of the interfered object can be obtained based on the weight value of the interfered object, and a second beam gain information corresponding to the post-interference weight value corresponding to each candidate phase value can be obtained based on the post-interference weight value corresponding to each candidate phase value, where the beam gain information includes gains of beams at different angles.

[0066] The first beam gain information and the second beam gain information can then be compared to determine null-filling information and beam distortion information corresponding to each candidate phase value, and then a target phase value can be determined from the multiple candidate phase values ​​based on the null-filling information and beam distortion information corresponding to each of the multiple candidate phase values.

[0067] Here, the null-filling information is used to indicate the null-filling effect of the beam, and the null-filling information may include the degree of increase in beam gain at each null position after the weight value of the interfering object is interfered with, and the beam distortion information is used to indicate the degree of distortion of the beam before and after interfering with the weight value of the interfering object, and the beam distortion information may be based on the degree of consistency of the change tendency of the beam shape before and after interfering with the weight value of the interfering object.

[0068] In practical applications, the null-filling effect is good, but the degree of beam distortion may be relatively serious. Therefore, in the present application, when determining a target phase value based on the null-filling information and the beam distortion information, the target phase value may be determined based on the weights of the null-filling information and the beam distortion information. Here, the weights of the null-filling information and the beam distortion information may be set based on actual needs. For example, when the weight corresponding to the null-filling information is large, the candidate phase value with a high null-filling effect may be selected as the target candidate phase value when determining the target phase value.

[0069] This makes it possible to determine null-filling information and beam gain information based on beam gain information before and after the weight value of the interfering object is interfered with by each candidate phase value, and to determine a phase value that can balance the null-filling effect and the degree of beam distortion from among multiple candidate phase values ​​based on the null-filling information and beam gain information.

[0070] In another possible implementation, a first beam gain information corresponding to the weight value of the interfered object and a second beam gain information corresponding to the post-interference weight value corresponding to each candidate phase value are determined, and a beam gain comparison map between the post-interference weight value corresponding to each candidate phase value and the interfered weight value is output and shown based on the first beam gain information and the second beam gain information, where the abscissa in the beam gain comparison map can be the beam angle and the ordinate can be the gain. Then, a user can determine the null-filling effect and the beam distortion effect corresponding to each candidate phase value based on the beam gain comparison map corresponding to each candidate phase value, thereby determining a required target phase value from a plurality of candidate phase values. When the phase value input by the user is obtained, the phase value input by the user can be the target phase value, where the phase value input by the user is one of a plurality of candidate phase values.

[0071] Here, the user inputting the phase value may be that the user inputs the phase value in the phase value input box of the display interface, or that a candidate phase value list is displayed on the display interface and the user selects one phase value from the candidate phase value list, but this application is not limited thereto. For example, Figures 4 and 5 are beam gain comparison diagrams before and after the weight value of the interference object is interfered with at two different candidate phase values ​​of the vertical beam, where the horizontal axis is angle, the vertical axis is gain, the dotted line is the original beam (i.e., the beam corresponding to the weight value of the interference object), and the solid line represents the null-filled beam (i.e., the beam corresponding to the weight value after interference). It can be seen that the effect of the null-filled beam in Figure 5 is better than that in Figure 4, but the degree of beam distortion in Figure 4 is smaller than that in Figure 5, and the candidate phase value used in Figure 4 can be taken as the target phase value.

[0072] This allows the user to determine the target phase value as needed by displaying a beam gain comparison map of before and after the weight value of the interference target is interfered with by each candidate phase value, thereby meeting the user's customization needs.

[0073] Step 305: determining a target beam weight matrix based on the target phase value, the weight value of the interferent, and the initial beam weight matrix.

[0074] Step 306, adjust the initial beam weight value matrix of the first polarization direction to the target beam weight value matrix.

[0075] In the present application, steps 305 to 306 are similar to those described in the above embodiment, and therefore a description thereof will be omitted.

[0076] In the embodiment of the present application, when determining a target phase value from a plurality of candidate phase values ​​based on the weight value of the interference target and the post-interference weight value corresponding to each candidate phase value, each candidate phase value among the plurality of candidate phase values ​​is used to perform interference processing on the weight value of the interference target to determine the post-interference weight value corresponding to each candidate phase value, and the target phase value can be determined from the plurality of candidate phase values ​​based on the weight value of the interference target and the post-interference weight value corresponding to each candidate phase value. This improves the beam null filling effect by determining the target phase value from the plurality of candidate phase values ​​based on the weight values ​​before and after interfering with the weight value of the interference target corresponding to each candidate phase value.

[0077] FIG. 6 is a schematic flow chart of a beam weight adjustment method provided by an embodiment of the present application.

[0078] As shown in FIG. 6, this beam weight adjustment method includes the following steps 601 to 610.

[0079] Step 601, obtain an initial beam weight matrix in a first polarization direction of a multi-transmit / receive channel antenna.

[0080] Step 602: Determine a weight value of an interference target in a first direction from an initial beam weight value matrix.

[0081] Step 603: Using each candidate phase value among the plurality of candidate phase values, an interference process is performed on the weight value of the interfered object to determine a post-interference weight value corresponding to each candidate phase value.

[0082] In this application, steps 601 to 603 are similar to those described in the above embodiment, and therefore a description thereof will be omitted.

[0083] Step 604: obtain the beam pointing deviation angle corresponding to each candidate phase value.

[0084] Since a null-filled beam may cause beam pointing deviation, the present application can determine first beam information corresponding to the weight value of the interfering object and second beam information corresponding to the post-interference weight value corresponding to each candidate phase value, and compare the first beam information with the second beam information to determine the beam pointing deviation angle before and after the weight value of the interfering object is interfered with. Here, the beam pointing deviation angle can refer to the deviation angle between the beam pointing corresponding to the post-interference weight value and the beam pointing corresponding to the weight value of the interfering object.

[0085] For example, the angle of the gain maximum position on the beam can be determined based on the first beam information, and the angle of the gain maximum position on the beam can be determined based on the second beam information, and the difference between these two angles can be taken as the beam pointing deviation angle.

[0086] Step 605: modifying the post-interference weight value according to the beam pointing deviation angle to obtain a modified weight value corresponding to each candidate phase value.

[0087] In the present application, the beam pointing deviation angle corresponding to each candidate phase value can be used to modify the post-interference weight value to obtain a modified weight value corresponding to each candidate phase value.

[0088] For example, the initial beam weight matrix for the first polarization direction is denoted as w above, and the first column weight value in w

[0090] In the present application, determining a target phase value based on beam information corresponding to the weight value of the interfering object and beam information corresponding to the modified weight value is similar to the method of determining a target phase value based on the weight value of the interfering object and the post-interference weight values ​​corresponding to each candidate phase value, and therefore will not be described here.

[0091] Step 607, determine a beam pointing deviation angle corresponding to the target phase value.

[0092] In the present application, when determining a target phase value, a beam pointing deviation angle corresponding to the target phase value can be determined.

[0093] Step 608: determining a modified weight value corresponding to the target phase value based on the weight value of the interferer, the target phase value and the corresponding beam pointing deviation angle.

[0095] For example, the target phase value is Φ0, the beam pointing deviation angle is ΔΦ, and Φ0 is used to perform interference processing on the first weight value among the weight values ​​w of the interference target determined from the initial beam weight value matrix w, and the weight value after interference is

[0099] Step 610, adjust the initial beam weight value matrix of the first polarization direction to the target beam weight value matrix.

[0100] In this application, step 610 is similar to the contents described in the above embodiment, so the description is omitted here.

[0101] In an embodiment of the present application, a beam pointing deviation angle corresponding to each candidate phase value is determined, the beam pointing deviation angle is used to modify the post-interference weight value to obtain the modified weight value, the weight value of the interference object and the modified weight value corresponding to each candidate phase value are used to determine a target phase value, and a target beam weight value matrix is ​​determined based on the weight value of the interference object, the target phase value and its corresponding beam deviation angle, thereby improving the accuracy of the target beam matrix and improving the null-filling effect.

[0102] In one embodiment of the present application, after determining the above target beam weight value matrix, an initial beam weight value matrix of a second polarization direction of the antenna can be further obtained, and the initial beam weight value matrix of the second polarization direction can be adjusted to the target beam weight value matrix, i.e., take the same beam weight value in another polarization direction, thereby obtaining a complete beam weight value matrix.

[0103] For example, the first direction is a vertical direction and the second direction is a horizontal direction, and the weight values ​​of a certain column of the initial beam weight values ​​in the first polarization direction are taken as the weight values ​​of the interference target, and interference processing is performed on the weight values ​​of the interference target based on the target phase value to obtain weight values ​​after interference, and the weight values ​​after interference are tensor-producted with the weight values ​​of a certain row in the initial beam weight value matrix to obtain a null-filled beam weight value matrix in the vertical dimension of the first polarization direction antenna, and the initial beam weight value matrix in the vertical dimension of the second polarization direction antenna can be adjusted to the null-filled beam weight value matrix in the vertical dimension of the first polarization direction antenna.

[0104] In addition, the beam weight adjustment method of the present application can not only adjust the beam weight values ​​of SSB beams, but also realize null filling in the vertical dimension of the SSB beam, and can also adjust the beam weight values ​​of other signals to realize null filling in other beams, and the present application is not limited thereto.
