[0002] With the introduction of 5G massive MIMO technology, compared to 4G, 5G shifts from pre-configured typical beam scenarios to custom beam configurations. The configuration methods in related technologies can include those based on geographic information, i.e., manual configuration based on the experience of optimization personnel, or configuration based on background recommendations.

[0003] However, configuration based on geographic information requires manual review and judgment, which is related to the optimization experience and technical level of the reviewers. This configuration requires a lot of human and time resources, and its accuracy and comprehensiveness are insufficient. On the other hand, configuration based on the backend can only configure parameters for standard scenarios, and its adaptability to special and complex scenarios is low. It cannot meet the ever-changing network optimization needs and lacks comprehensiveness and flexibility. Summary of the Invention

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The following is in conjunction with the appendix Figures 1 to 5 The present application provides a detailed description of a beam configuration method, apparatus, and computer program product through specific embodiments and application scenarios.

[0025] like Figure 1 The diagram shown is a flowchart of a beam configuration method provided in an embodiment of this application. Figure 1 As shown, the beam configuration method may include the contents shown in S101 to S103.

[0026] In S101, based on the sampling points in the measurement report and the SSB beam information of the synchronization signal module, the beam to be evaluated and the uplink transmission angle information are determined.

[0027] The beams to be evaluated include horizontal beams and vertical beams, and the uplink transmission angle information includes the antenna's horizontal angle of arrival and the antenna's vertical angle of arrival.

[0028] It should be noted that the Measurement Report (MR) includes the horizontal angle of arrival (MR.hAOA) of the 5G base station (NextGeneration NodeB, gNB) antenna, the vertical angle of arrival (MR.vAOA) of the gNB antenna, and the Identifier (ID) of the Synchronization Signaling Block (SSB) occupied by users in the New Radio (NR) serving cell (MR.NRScSSBIndexId).

[0029] MR.hAOA refers to the estimated angle of the user relative to the horizontal direction of the reference direction, which is the horizontal angular direction of the antenna. MR.hAOA is the counterclockwise angle relative to the reference direction, with an accuracy of 0.5 degrees or other degrees, depending on the actual application. It is applicable to gNBs with multiple antennas. When the number of antennas is less than or equal to a preset value, such as 4, the measurement item value is NIL. For user equipment (UE) accessing a pico base station, the measurement item MR.hAOA value is NIL. The value range is shown in Table 1, where the first column represents the sample values ​​actually reported by the northbound interface of the Radio Access Network Element Management System (OMC-R), and the value type is integer. This measurement data MR.hAOA can be used to determine the user's location to provide positioning services.

[0032] MR.vAOA refers to the estimated angle of the user relative to the reference direction in the perpendicular direction, such as... Figure 2 As shown, the reference direction is the normal direction of the antenna panel, and MR.vAOA is the downward angle relative to the reference direction, with an accuracy of 1 degree. Other degrees can also be used, depending on the actual application. This applies to gNBs with multiple antennas. When the number of antennas is less than or equal to a preset value, such as 16, the measurement item MR.vAOA is set to NIL. For UE accessing a pico base station, the measurement item is set to NIL. The value range is shown in Table 2. This measurement data MR.vAOA can be used to determine the user's location to provide positioning services.

[0035] In S102, the downlink simulated transmission angle information is determined based on the vectors of the horizontal beam and the vertical beam.

[0036] The downlink simulated transmission angle information includes the simulated downlink horizontal transmission angle and the simulated downlink vertical transmission angle.

[0037] Here, a vector refers to the beam's vector in a planar coordinate system, which includes both direction and length.

[0038] In S103, the beam configuration is determined based on the difference between the simulated downlink horizontal transmission angle and the antenna horizontal angle of arrival, and the difference between the simulated downlink vertical transmission angle and the antenna vertical angle of arrival.

[0039] It should be noted that in a Time-Division Duplex (TDD) system, uplink and downlink transmissions occur on the same frequency. When the transmission time interval between uplink and downlink is sufficiently short, the fading of the uplink and downlink channels can be considered to be essentially the same, meaning that the uplink and downlink channels in a TDD system are reciprocal. Therefore, the direction of base station transmission can be deduced from the beam measurement information received by the terminal, while the base station can infer the approximate transmission direction of the terminal from the AOA information transmitted from the terminal to the antenna receiver. If the difference between the two is too large, it is determined that the terminal may not be within the effective coverage area of ​​the beam, for example, due to the lack of main control beam coverage, the terminal receiving multiple beam signals of similar strength, and signal clutter leading to a large difference between the statistically calculated downlink transmission angle and the AOA. In this embodiment, the difference between uplink and downlink transmission angles is used to determine whether the beam configuration is reasonable.

[0040] In this embodiment, firstly, based on the sampling points and SSB beam information of the synchronization signal module in the measurement report, the beam to be evaluated and the uplink transmission angle information are determined. The beam to be evaluated includes a horizontal beam and a vertical beam. The uplink transmission angle information includes the antenna's horizontal angle of arrival and the antenna's vertical angle of arrival. Then, based on the vectors of the horizontal and vertical beams, the downlink simulated transmission angle information is determined. The downlink simulated transmission angle information includes the simulated downlink horizontal transmission angle and the simulated downlink vertical transmission angle. Finally, based on the difference between the simulated downlink horizontal transmission angle and the antenna's horizontal angle of arrival, and the difference between the simulated downlink vertical transmission angle and the antenna's vertical angle of arrival, the beam configuration is determined. This embodiment, based on the measurement report data and SSB beam information reported by the terminal, ensures greater accuracy of the data, thereby identifying whether the beam configuration is reasonable and improving the accuracy and adaptability of the beam configuration.

[0041] In one possible implementation of this application, determining the beam to be evaluated based on each sampling point in the measurement report and the SSB beam information of the synchronization signal module may include: selecting a target sub-beam based on each sampling point in the measurement report; and determining the beam to be evaluated based on the target sub-beam and the SSB beam information of the synchronization signal module, wherein the beam to be evaluated includes a horizontal beam and a vertical beam.

[0042] The target sub-beam is the strongest sub-beam among the MR sampling points. The strongest sub-beam is the beam at the intersection of the horizontal and vertical directions. As shown in Table 3, the beam with sub-beam ID 1 is the strongest sub-beam among the MR sampling points.

[0043] Table 3

[0044] Sub-beam ID Belongs to NCGI downhill angle Azimuth Beam Classification 0 A 2 320 Vertical beam 1 A 6 320.5 Strongest sub-beam 2 A 10 320 Vertical beam 3 A 6 346.5 Horizontal beam 4 A 6 0 Horizontal beam 5 A 6 13.5 Horizontal beam 6 A 6 26.5 Horizontal beam 7 A 6 39.5 Horizontal beam

[0045] In this embodiment, based on the strongest sub-beam and combined with the azimuth angle corresponding to the SSB beam information in the network management system, the beams to be evaluated in the horizontal and vertical directions are determined.

[0046] In other words, the beam to be evaluated can be determined by using the strongest sub-beam in the MR sampling points as the statistical starting point and combining it with the azimuth angle corresponding to the SSB beam information. For example, taking the default scenario configuration as an example, with a horizontal beamwidth of 105 degrees and 8 sub-beams, taking the beam azimuth angle of the cell with an azimuth angle of 0 degrees as an example, some sub-beam azimuth angles can be determined. Then, using the azimuth angle of the strongest sub-beam as the starting point, the horizontal beam to be evaluated can be determined. Similarly, the sub-beam downtilt angle can also be determined. Then, using the downtilt angle of the strongest sub-beam as the starting point, the vertical beam to be evaluated can be determined.

[0047] It is worth noting that if |sub-beam azimuth angle - strongest sub-beam azimuth angle| ≤ 20 degrees, they can be determined to be beams in the same vertical plane; if |sub-beam downtilt angle - strongest sub-beam downtilt angle| ≤ 3 degrees, they can be determined to be beams in the same horizontal plane. The values ​​of 20 degrees and 3 degrees can be changed according to the actual situation, and the actual application shall prevail. This embodiment does not limit them.

[0048] In one possible implementation of this application, determining the downlink simulated transmit angle information based on the vectors of the horizontal and vertical beams may include: determining the vector of the horizontal beams based on the azimuth angles of all horizontal beams and the received power intensity of the reference signal; determining the simulated downlink horizontal transmit angle based on the vector of the horizontal beams; determining the vector of the vertical beams based on the azimuth angles of all vertical beams and the received power intensity of the reference signal; and determining the simulated downlink vertical transmit angle based on the vector of the vertical beams.

[0049] The azimuth angle of the horizontal beam can be as follows: Figure 3 As shown, Figure 3 Taking the default scenario configuration as an example, with a horizontal beamwidth of 105 degrees and 8 sub-beams, some sub-beam azimuth angles can be obtained, as shown in Table 4. Among them, the NGGI is the 5G cell ID (NR Cell Global Identifier).

[0052] Based on Table 4 above and the strongest sub-beam, the horizontal beam information can be obtained through matching. The reference signal receiving power (RSRP) intensity of the horizontal beam can be determined, and thus the vector of the horizontal beam can be determined. For example... Figure 4 As shown, the dark arrows represent vectors corresponding to multiple beam information points in the MR sampling points. By adding them one by one, the vector corresponding to the light arrow can be obtained, and thus its azimuth angle, i.e., the vector of the horizontal beam, can be obtained. The specific vector addition process is not described in detail in this application, but the existing vector addition algorithm shall prevail.

[0053] Accordingly, based on the list of vertical beams obtained by matching the strongest sub-beam, the simulated downtilt angle in the vertical direction, i.e. the simulated down-going vertical transmission angle, can be obtained using a vector algorithm, as shown in Table 5.

[0055] Belongs to NCGI Beam number Sub-beam downtilt angle A #0 6 A #1 6 A #2 4 A #3 6 A #4 6 A #5 4 A #6 4 A #7 4

[0056] Based on the above steps, the downlink simulated transmission angle information of the MR sampling points under cell A can be output, namely the simulated downlink horizontal transmission angle and the simulated downlink vertical transmission angle, as shown in Table 6.

[0057] Table 6

[0058]

[0059] In this embodiment, the vectors of all beams are determined based on the azimuth angles of all beam vectors and RSRP. By adding the vectors together, the downlink signal transmission angle and downtilt angle of each user at each MR sampling point can be simulated, that is, the simulated downlink horizontal transmission angle and the simulated downlink vertical transmission angle.

[0060] Specifically, the vectors can be obtained using the beam vector and RSRP weights, and then the vectors can be added together to obtain the simulated downlink horizontal transmission angle and the simulated downlink vertical transmission angle.

[0061] For example, given the azimuth angles and RSRP intensities of two beams a and b, the sum of the two beam vectors can be obtained by transforming the coordinate system and applying the parallelogram law, and the new azimuth angle can be calculated at the same time.

[0062] Beam a: RSRP intensity is -80, its weight value is -80 + 150 = 70, beam azimuth angle θ1 = 340 degrees.

[0063] We can obtain: a1=70*sinθ1=-23.9; a2=70*cosθ1=65.8, where (a1, a2) are the coordinates of the endpoint of the vector of beam a;

[0064] Beam b: RSRP intensity is -70, its weight value is -70 + 150 = 80, beam azimuth angle θ2 = 60 degrees.

[0065] We can obtain: b1 = 80 * sinθ2 = 69.3; b2 = 80 * cosθ2 = 40, where (b1, b2) are the coordinates of the endpoint of the vector of beam b;

[0066] After merging, the beam c has the following coordinates: c1 = a1 + b1 = 45.4; c2 = a2 + b2 = 105.8. Therefore, θ3 = arctan(c1 / c2) = 23.2 degrees, where (c1, c2) are the coordinates of the endpoint of the vector of beam c.

[0067] Where 150 is the compensation value, which can also be other values. In order to make the RSRP strength of the beam positive and facilitate subsequent calculations, the compensation value can be determined according to actual needs, and this application does not limit it.

[0068] In one possible implementation of this application, determining the beam configuration based on the difference between the simulated downlink horizontal transmission angle and the antenna horizontal angle of arrival, and the difference between the simulated downlink vertical transmission angle and the antenna vertical angle of arrival, may include: determining the corresponding sampling point in the measurement report as a reasonable sampling point when the difference between the simulated downlink horizontal transmission angle and the antenna horizontal angle of arrival is less than or equal to a first threshold, and the difference between the simulated downlink vertical transmission angle and the antenna vertical angle of arrival is less than or equal to a second threshold; determining the corresponding sampling point in the measurement report as an unreasonable sampling point when the difference between the simulated downlink horizontal transmission angle and the antenna horizontal angle of arrival is greater than the first threshold, and / or the difference between the simulated downlink vertical transmission angle and the antenna vertical angle of arrival is greater than the second threshold; and determining the beam configuration based on the reasonable and unreasonable sampling points.

[0069] In other words, since uplink and downlink transmissions in a TDD system operate on the same frequency, when the transmission time interval between uplink and downlink is sufficiently short, the fading of the uplink and downlink channels can be considered essentially the same, meaning that uplink and downlink channels in a TDD system are reciprocal. Therefore, the direction of base station transmission can be inferred from the beam measurement information received by the terminal, while the base station can infer the approximate transmission direction of the terminal from the AOA information transmitted from the terminal to the antenna receiver. If the difference between the two is too large, it is determined that the terminal may not be within the effective coverage area of ​​the beam, for example, due to a lack of main control beam coverage, or the terminal receiving multiple beam signals of similar strength, resulting in signal clutter and a large difference between the statistically calculated downlink transmission angle and the AOA. That is, a large difference between the simulated downlink and uplink values ​​indicates that the sampling points are unreasonable, while a smaller difference indicates they are reasonable. Based on reasonable and unreasonable sampling points, the rationality of the beam configuration can then be determined.

[0070] The judgment criteria can be whether |simulated downlink horizontal emission angle - MR.hAOA| ≤ 10 and |simulated downlink vertical emission angle - MR.vAOA| ≤ 3. Here, 10 and 3 can be set as needed; this embodiment does not impose a limitation, and the actual application shall prevail.

[0071] Based on the above embodiments, it can be determined whether the sampling points meet the requirements, as shown in Table 7.

[0072] Table 7

[0073]

[0074] In one possible implementation of this application, determining the beam configuration based on reasonable and unreasonable sampling points may include: determining the proportion of reasonable sampling points based on reasonable and unreasonable sampling points; and determining that the beam configuration is reasonable if the proportion of reasonable sampling points is greater than or equal to a proportional threshold.

[0075] In one possible implementation of this application, the beam configuration method may further include: if the proportion of reasonable sampling points is less than a proportional threshold, determining that the beam configuration is unreasonable, and identifying the sampling points corresponding to the unreasonable beam configuration, wherein the sampling points include the antenna horizontal angle of arrival and the antenna vertical angle of arrival.

[0076] The ratio threshold can be set based on experience or historical data, depending on the actual application. This embodiment does not impose any limitations.

[0077] In other words, beam-level convergence can be performed based on Table 7, and the proportion of reasonable sampling points under each sub-beam can be counted as shown in Table 8. This will help determine whether the beam configuration is reasonable. If the proportion is greater than or equal to the proportion threshold, the beam configuration is relatively reasonable and no adjustment is needed. If the proportion is less than the proportion threshold, the beam configuration is unreasonable and adjustment is required.

[0078] Table 8

[0079]

[0080] For example, a ratio threshold of 60% can be set, that is, for sampling points with a ratio of <60%, it is determined that the beam configuration is unreasonable, and the vertical / horizontal AOA range value corresponding to the actual MR sampling point under the beam is output, as shown in Table 9.

[0081] Table 9

[0082]

[0083] In one possible embodiment of this application, the beam configuration method may further include: adjusting at least one of the following based on the antenna horizontal angle of arrival and antenna vertical angle of arrival of the sampling point corresponding to the improperly configured beam: the azimuth angle and downtilt angle of the beam; the number of vertical beams; and the number of horizontal beams.

[0084] In other words, beam optimization adjustments can be made based on Tables 8 and 9. For example, based on the proportion of unreasonable sampling points at the beam level, problem beams can be identified, and differences in the coverage scenarios of problem beams can be identified, such as obstructed, high-rise, and water-based scenarios, and beam optimization can be performed for these scenarios. Based on the horizontal and vertical AOA information distribution of MR sampling points under the problem beam, beam parameters can be adjusted for each row to adapt to the actual business needs of users within the beam range, such as adjusting the beam azimuth angle and downtilt angle, or adding a vertical beam to cover high-rise buildings to increase the coverage area of ​​the sub-beam.

[0085] This application's embodiments employ MR data and network management-side beam configuration data to assess the rationality of user sampling points based on the consistency characteristics of base station-side transmitted / received signals. It also incorporates horizontal and vertical beam coverage consistency assessments, inferring the coverage matching degree of 5G cell beam parameter configurations within the area, thereby quantitatively identifying problematic sub-beams and overcoming the shortcomings of traditional verification methods in terms of accuracy and comprehensiveness. Based on beam-level statistical information, a vector algorithm is introduced to assess the actual user distribution of each sub-beam under the cell. Rapid assessment can be completed using only MR data and network management-side beam configuration information, reducing reliance on engineering parameters and geographic information. This results in higher data collection accuracy, more targeted optimization, and significantly improved work efficiency.

[0086] like Figure 5 The diagram shown is a schematic representation of a beam configuration device provided in an embodiment of this application. Figure 5 As shown, the beam configuration device may include: a first determining module 501, a second determining module 502, and a third determining module 503.
