[0001] The present application relates to the field of antenna technology, and in particular to a method for determining a radio frequency configuration, an electronic device, a storage medium, and a program product. Background Art

[0002] As low-altitude economy becomes a national strategy, operators face the challenge of how to economically and efficiently build mobile networks that meet signal coverage requirements in specific airspaces.

[0003] In the existing technology, the appropriate antenna type is selected based on certain experience, such as multi-beam antennas for high-rise buildings and wide beams for open squares. Most of the antenna types are selected based on certain experience, and this selection method may have certain errors. As for the actual measurement method, considering the cost reasons, when facing services with a large airspace range, the measurement data that can be obtained is small and random. It is impossible to directly analyze the overall coverage of the antenna under a specific solution based on the actual measurement data, and the number of solutions that can be measured is limited. Therefore, the existing technology has the problems of low accuracy and poor flexibility. Summary of the invention

This method can carefully evaluate the coverage of antenna signals in the vertical direction. By measuring the signal coverage at each height layer, the signal coverage effect within the entire airspace can be more comprehensively and accurately understood.

[0036] A call bill data recording method provided by the present application will be described in detail below with reference to the accompanying drawings.

[0037] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0038] The terms "first" and "second" and the like in the specification and drawings of this application are used to distinguish different objects, or to distinguish different processing of the same object, rather than to describe a specific order of objects.

[0039] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include other steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0040] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0041] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second", etc. are used to distinguish the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second", etc. are not limiting the quantity and execution order.

[0042] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0043] As the low-altitude economy is included in the national strategic plan, research on low-altitude network coverage technology has become increasingly urgent. Low-altitude networks are different from conventional ground mobile communication networks. They not only need to cover a wide horizontal area, but also ensure three-dimensional coverage at a certain height to meet the needs of low-altitude services. This requires operators to develop network solutions that can cover airspace several kilometers away and tens of meters to thousands of meters high. However, not all existing base station radio frequency forms are suitable for low-altitude coverage, and careful evaluation and selection of suitable equipment are required. This requires a set of effective means to intuitively compare the coverage effects of different configuration schemes and establish a scientific evaluation system.

[0044] In the prior art, due to the limited capabilities of measurement tools, when measuring three-dimensional airspace coverage with a large actual measurement range, the selected sampling points are relatively small and random in number relative to the overall airspace. Therefore, the coverage features obtained are also relatively few, and key problem points may be missed during the test process. It is difficult to achieve a comprehensive test of the entire airspace, and it is impossible to accurately evaluate the actual overall coverage capability of the network.

[0045] In response to the above technical problems, the present application provides a resource optimization method, the idea of ​​which is: when the antenna unit of the base station is configured as different radio frequency configuration schemes, determine the coverage effect of the base station within the target airspace; the coverage effect of the base station within the target airspace is determined based on the signal coverage of at least one altitude layer of the base station within the target airspace; based on the coverage effect of the base station within the target airspace, determine the optimal radio frequency configuration scheme of the antenna unit. This application divides the height in the target airspace and divides different altitude layers for different radio frequency configuration schemes of the antenna unit of the base station. By obtaining the signal coverage of different altitude layers and combining different altitude layers for overall analysis, the coverage effect within the target airspace under the same radio frequency configuration scheme is obtained, and finally the optimal radio frequency configuration scheme is determined based on the coverage effect of different radio frequency configuration schemes. This method can carefully evaluate the coverage of the antenna signal in the vertical direction. By measuring the signal coverage at each altitude layer, the signal coverage effect within the entire airspace can be more comprehensively and accurately understood. At the same time, the density division of the altitude layer can be adjusted as needed to adapt to different coverage requirements and accuracy requirements, thereby improving the flexibility of the method.

[0046] The following is a detailed introduction to the method for determining the radio frequency configuration provided in the embodiment of the present application in conjunction with the drawings of the specification.

[0047] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, for example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, etc. These various systems all include terminal equipment and access network side equipment (such as a base station). The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0048] The solution provided in the embodiment of the present application can be executed by an electronic device. For example, the electronic device can be a server cluster composed of multiple servers, or a single server, or a computer, or a processor or processing chip in a server or computer. The embodiment of the present application does not limit the specific device form of the electronic device.

[0049] It should be noted that the application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0050] The following is a detailed introduction to the method for determining the radio frequency configuration provided in an embodiment of the present application.

[0051] Figure 1A flowchart of a method for determining a radio frequency configuration provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes:

[0052] S100: Based on different radio frequency configuration schemes corresponding to antenna units of the base station, determine the coverage effects of the base station within a target airspace under different radio frequency configuration schemes.

[0053] Among them, different RF configuration schemes include at least one of the following: respectively configured as different antenna types; respectively configured as different beams under each antenna type; respectively configured as different elevation angles under each antenna type.

[0054] In some embodiments, the antenna unit may be a single antenna or a device including an antenna. Exemplarily, it may be an active antenna unit (AAU), which is a device that integrates an antenna and a radio frequency processing unit. This application does not limit this.

[0055] Illustratively, the different antenna types may be antennas of different models manufactured by different manufacturers, or may be antennas with different functions.

[0056] In some embodiments, the coverage effect of the base station within the target airspace is determined based on the signal coverage of the base station at at least one altitude layer within the target airspace. The specific process is introduced in steps S110-S130 below and will not be repeated here.

[0057] S200: Determine an optimal radio frequency configuration scheme for the antenna unit based on the coverage effect of the base station within the target airspace.

[0058] In some embodiments, the optimal RF configuration scheme of the antenna unit is determined by comparing the coverage effect of the base station within the target airspace with the actual coverage effect requirement.

[0059] In some embodiments, in actual applications, factors such as cost are also taken into consideration to select the optimal RF configuration solution that meets the needs of the operator.

[0060] It is understandable that the present application is aimed at different RF configuration schemes of the antenna unit of the base station, and the height is divided in the target airspace to divide different height layers. By obtaining the signal coverage of different height layers and combining the different height layers for overall analysis, the coverage effect within the target airspace under the same RF configuration scheme is obtained, and finally the optimal RF configuration scheme is determined based on the coverage effect of different RF configuration schemes. This method can carefully evaluate the coverage of the antenna signal in the vertical direction. By measuring the signal coverage at each height layer, the signal coverage effect within the entire airspace can be more comprehensively and accurately understood. At the same time, the density division of the height layer can also be adjusted as needed to adapt to different coverage requirements and accuracy requirements, thereby improving the flexibility of the method.

[0061] In some embodiments, the signal coverage condition includes: a maximum horizontal coverage radius, such as Figure 2 As shown, the above-mentioned determination of the coverage effect of the base station within the target airspace is specifically implemented by the following steps S110-S130:

[0062] S110: For each altitude layer in at least one altitude layer in the target airspace range, respectively obtain a reference symbol signal level value of a sampling point of each altitude layer.

[0063] The reference symbol signal represents different signals in different communication networks. For example, in a 4G network, it represents a cell reference signal (CRS), and in a 5G network, it represents a synchronization broadcast block (Synchronization

[0064] Signal / PBCH, SSB) related primary synchronization signal (Primary Synchronization

[0065] Signal, PSS) and secondary synchronization signal (Secondary Synchronization Signal, SSS).

[0066] As a possible implementation, Figure 3 As shown, the above-mentioned acquisition of the reference symbol signal level value of the sampling point of each altitude layer includes:

[0067] S11: Obtain the location information of multiple sampling points at each altitude layer.

[0068] Exemplarily, multiple different altitude layers (e.g., 100m, 150m, ..., 300m, ..., 600m) are selected, and sampling points (e.g., 100m) are set with a certain granularity within a certain horizontal distance range (e.g., 3000m) in the east-west, south-north direction of the base station with the base station as the center.

[0069] S12: For each sampling point among the multiple sampling points, determine the antenna gain of each sampling point according to the position information of each sampling point.

[0070] The specific implementation process of the above step S12 is introduced in the following steps S1201-S1203 and will not be repeated here.

[0071] S13: Determine the propagation loss from the base station to each sampling point according to the distance between each sampling point and the base station.

[0072] The distance between the sampling point and the base station is the straight-line distance between the sampling point and the base station, and the propagation loss from the base station to the sampling point is calculated using a propagation loss formula of a commonly used propagation model (usually a low-altitude propagation model).

[0073] S14: Determine a reference symbol signal level value of each sampling point based on the antenna gain of each sampling point, the propagation loss from the base station to each sampling point, and the reference symbol power configuration value of the base station.

[0074] Specifically, the reference symbol signal level value of each sampling point is determined according to the following method: the reference symbol signal level value of the sampling point = the antenna gain of the sampling point + the reference symbol power configuration value of the base station - the propagation loss from the base station to the sampling point.

[0075] Among them, the reference symbol power configuration value of the base station is provided by the antenna manufacturer and no additional measurement is required. For example, for a 5G active antenna unit with a bandwidth of 100MHz, the power configuration value is typically 17.8dBm.

[0076] In some embodiments, a table of reference symbol signal level values ​​of sampling points can be prepared by using an Excel spreadsheet tool, as shown in Table 1, which is an example of a table of reference symbol signal level values ​​of sampling points provided in an embodiment of the present application:

[0077] Table 1

[0078]

[0079] Table 1 shows that the sampling points are set at a granularity of 100 m, with the base station as the center, within a range of 3000 m in the east, west, south and north directions of the base station.

[0080] In some embodiments, the cells of different data in the above table (Table 1) are hierarchically colored by the conditional formatting function of the Excel table tool, so as to intuitively display the exemplary high-level slices, such as Figure 4 The figure shows an example of layered coloring of the reference symbol signal level value table of sampling points at three altitude layers (a is 100m, b is 200m, and c is 300m) in the same configuration scheme.

[0081] In some embodiments, the row width and column width of the corresponding cell can be adjusted according to the granularity to more realistically reflect the geographical location differences.

[0082] In some embodiments, Figure 5 As shown, step S12 can be specifically implemented as the following steps S1201-S1203:

[0083] S1201: Determine the orientation relationship of each sampling point relative to the base station according to the position information of each sampling point.

[0084] The position information of each sampling point is the position of the sampling point in the global coordinates; the orientation relationship of each sampling point relative to the base station is the orientation relationship of the sampling point relative to the position of the base station in the global coordinates.

[0085] S1202: Based on the azimuth relationship of each sampling point relative to the base station, determine the horizontal angle and vertical angle of each sampling point relative to the normal direction of the antenna unit of the base station.

[0086] S1203: Determine the antenna gain of each sampling point based on the horizontal angle and the vertical angle of each sampling point relative to the normal direction of the antenna unit of the base station and a preset corresponding relationship.

[0087] Among them, the preset corresponding relationship is used to indicate the antenna gain corresponding to the first horizontal angle and the first vertical angle, the first horizontal angle is any horizontal angle in the preset horizontal angle range of the normal direction of the antenna unit of the base station, and the first vertical angle is any vertical angle in the preset vertical angle range of the normal direction of the antenna unit of the base station.

[0088] It can be understood that the preset corresponding relationship is the antenna gain corresponding to any horizontal angle in the preset horizontal angle range of the normal direction of the antenna unit of the base station and any vertical angle in the preset vertical angle range of the normal direction of the antenna unit of the base station. For each antenna type in different RF configuration schemes, different pitch angles are configured respectively. The antenna pitch angle is different, and the azimuth angle of the sampling point within the preset angle range relative to the defense line direction of the antenna unit of the base station is also different. Therefore, converting the azimuth relationship of the sampling point relative to the base station into the horizontal angle and vertical angle of the sampling point relative to the normal direction of the antenna unit of the base station helps to more accurately determine the antenna gain of the sampling point under different RF configuration schemes.

[0089] In some embodiments, the above preset correspondence relationship is determined based on the following method:

[0090] A1: Obtain the basic antenna gain correspondence relationship of the antenna unit of the base station.

[0091] The corresponding relationship of the basic antenna gain of the antenna unit of the base station is used to indicate at least one basic antenna gain corresponding to multiple sub-beams of the radio frequency of the antenna unit of the base station at the first horizontal angle and the first vertical angle.

[0092] The first horizontal angle is any horizontal angle in a preset horizontal angle range of the normal direction of the antenna unit of the base station, and the first vertical angle is any vertical angle in a preset vertical angle range of the normal direction of the antenna unit of the base station.

[0093] In some embodiments, the basic antenna gain correspondence relationship of the antenna unit of the base station may be directly provided by the antenna manufacturer, that is, the basic antenna gain correspondence relationship of the antenna unit of the base station may be factory test data.

[0094] In some embodiments, after obtaining the basic antenna gain correspondence relationship of the antenna units of the base station from the antenna manufacturer, the present application can generate a basic antenna gain correspondence relationship table of the antenna units of the base station by inputting the basic antenna gain correspondence relationship of the antenna units of the base station into an Excel spreadsheet tool.

[0095] A2: The maximum value of multiple sub-beams of the radio frequency of the antenna unit of the base station in at least one basic antenna gain corresponding to the first horizontal angle and the first vertical angle is used as the antenna gain of the antenna unit of the base station corresponding to the first horizontal angle and the first vertical angle to obtain a preset corresponding relationship.

[0096] In some embodiments, a preset correspondence table can be created by using an Excel spreadsheet tool. For example, Table 2 is an example of a preset correspondence table provided in an embodiment of the present application, where the first row is the horizontal angle of the normal direction of the base station antenna unit (-180 degrees to 179 degrees), and the first column is the vertical angle of the normal direction of the base station antenna unit (-90 degrees to 90 degrees).

[0097] Table 2

[0098]

[0099]

[0100] It should be noted that the angle division shown in Table 2 is a division with a granularity of 2 degrees, and the granularity of the angle division can be adjusted according to actual needs.

[0101] In some embodiments, the cells of different data in the above table (Table 2) are colored by the conditional formatting function of the Excel spreadsheet tool, so as to more intuitively present the overall envelope of the antenna.

[0102] Exemplarily, cells within -3dB of the maximum gain value may be filtered and colored separately to present the overall envelope 3dB bandwidth shape of the antenna unit within the target airspace.

[0103] For example, Figure 6 The figure shows the overall gain of the antenna unit within the target airspace under a configuration scheme after segmented and layered coloring using the Excel conditional formatting color scale function.

[0104] In some embodiments, relevant personnel can perform layered coloring based on the above tables (Table 1, Table 2) Figure 4 , Figure 6 ) to analyze and pre-select solutions to screen out solutions that may meet actual needs, or when all configuration solutions cannot meet actual coverage requirements, the problem is analyzed through colored schematic diagrams so that antenna manufacturers can improve antenna products based on the analysis results.

[0105] It should be noted that, in actual calculation, the antenna gain of the base station sector (ie, the primary serving cell) with the largest signal strength at the sampling point is usually selected as the antenna gain of the sampling point.

[0106] S120: Determine the maximum horizontal coverage radius of each altitude layer based on the reference symbol signal level value of the sampling point of each altitude layer.

[0107] In some embodiments, the above step S120 can be specifically implemented as follows: performing segmented statistics based on the reference symbol signal level value of the sampling point of each altitude layer, and determining the maximum horizontal coverage radius of each altitude layer based on the preset threshold value and preset ratio of the reference symbol signal level value.

[0108] The maximum horizontal coverage radius is the radius of the target area in at least one area centered on the base station, and the target area is an area where the proportion of sampling points whose reference symbol signal level values ​​meet the preset threshold value in all sampling points in the target area is greater than or equal to the preset proportion.

[0109] S130: Determine the coverage effect of the target airspace range based on the maximum horizontal coverage radius of each altitude layer.

[0110] In some embodiments, the coverage effect within the target airspace range includes a maximum coverage radius and a maximum station distance within the target airspace range.

[0111] Among them, the maximum station spacing within the target airspace is usually determined according to the maximum coverage radius within the target airspace. Exemplarily, the maximum station spacing is usually 1.5 times the maximum coverage radius.

[0112] In some embodiments, the coverage effect of the target airspace range is determined by overall analyzing the maximum horizontal coverage radius of each altitude layer within the target airspace range. For example, the minimum value of the maximum horizontal coverage radius of each altitude layer can be selected as the maximum coverage radius within the target airspace range.

[0113] It is understandable that this application measures the signal level value at the sampling point of each altitude layer by configuring different antenna types, beams and pitch angles, obtains signal coverage data at different altitude layers, and then conducts comprehensive analysis to achieve a detailed evaluation of the entire airspace signal coverage and determine the optimal RF configuration scheme to meet the signal coverage requirements within a specific airspace. This method can more accurately understand the signal coverage in the vertical direction, while improving the accuracy and flexibility of signal coverage analysis, allowing operators to select the most appropriate RF configuration scheme based on specific coverage requirements and cost considerations, thereby economically and efficiently building low-altitude mobile networks.

[0114] On the other hand, compared with the method of obtaining signal coverage effect by simulating environment in the prior art, the RF configuration determination method provided in the embodiment of the present application is calculated based on the known data provided by the antenna manufacturer, without the need for data measurement, and the calculation method is transparent, thus avoiding the problem that the final results cannot be uniformly compared due to different simulation configurations and simulation tools used by different experimenters during simulation, and has stronger universality. At the same time, since the environmental simulation process is omitted, the analysis time can be shortened, thereby improving the efficiency of the RF configuration determination process.
