Detailed Implementation
[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, and 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] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0024] It should also be noted that in the embodiments of this application, "of", "corresponding", and "corresponding" can sometimes be used interchangeably. It should be pointed out that when their differences are not emphasized, their meanings are consistent.
[0025] To facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first" and "second" are used in the embodiments of this application to distinguish the same or similar items with essentially the same function and effect. Those skilled in the art can understand that the terms "first" and "second" are not intended to limit the quantity or execution order.
[0026] Before providing a detailed explanation of the embodiments of this application, some technical terms and related technologies involved in the embodiments of this application will be introduced first.
[0027] Currently, the industry has begun research and construction of 5G networks. In 5G networks, Massive Multiple-Input Multiple-Output (MIMO) technology and the concept of beams are introduced, allowing a cell to be covered by multiple beams.
[0028] In multi-carrier coverage scenarios, related technologies typically employ a single beam configuration scheme to configure the beams of each carrier, meaning that different carriers generally use the same coverage mode, such as equal beamwidth coverage (the beams of each carrier transmitted by the antenna are of equal beamwidth).
[0029] However, due to the complexity and diversity of the wireless environment within the coverage scenario, such as a base station sector often needing to cover multiple scenarios, even in multi-carrier scenarios, the use of a single coverage mode for each carrier is insufficient to meet the needs of multi-scenario coverage. Traditional multi-scenario coverage solutions require additional cell and board hardware, base station antennas, and other equipment, and precise scenario coverage is crucial to avoid impacting network quality. Therefore, traditional coverage methods suffer from high costs, long processing times, low efficiency, and unsatisfactory results.
[0030] In view of this, embodiments of this application provide a beam coverage management method, which can adapt the coverage scenario to the beam configuration based on 5G Massive MIMO and beamforming technologies to meet the coverage requirements of multiple scenarios.
[0031] The beam coverage management method provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0032] The beam coverage management method provided in this application can be applied to wireless communication systems. Figure 1 A schematic diagram of one structure of this wireless communication system is shown. For example... Figure 1 As shown, the wireless communication system 10 includes a beam coverage management device (hereinafter referred to as the management device) 11 and a network device 12. The management device 11 and the network device 12 can be connected via a wired or wireless connection; this embodiment does not limit the connection in this regard.
[0033] The wireless communication system 10 can be a 5G communication system, or a multi-carrier wireless communication system including third-generation (3G) systems, fourth-generation (4G) systems, and 5G systems.
[0034] The management device 11 is used to acquire coverage requirement information of the target cell. The management device 11 is also used to, when a target scenario type exists in the coverage requirement information, configure a first carrier based on a first configuration strategy to enable the first carrier to cover the target scenario type, and configure a second carrier based on a second configuration strategy to enable the second carrier to cover non-target scenario types in the target cell.
[0035] Optional, such as Figure 2 As shown, the management device 11 includes an environmental data module S1, an engineering parameter module S2, a statistical acquisition module S3, a configuration acquisition module S4, and a computer service module S5. The environmental data module S1 is used to digitally model the regional map. The engineering parameter module S2 is used to collect tilt angle, azimuth angle, altitude, and latitude / longitude information for each cell. The statistical acquisition module S3 is used to collect real-time key performance indicators (KPIs) at the cell level for professional network management, to evaluate the effectiveness of the implementation plan. The configuration acquisition module S4 is used to collect parameters such as beam and downtilt of the professional network management cells and carrier configuration strategies. The computer service module S5 provides computing power services to each module.
[0036] Network device 12 is equipped with an antenna array and transmits beams through the antenna array to provide communication services to user equipment within its coverage area.
[0037] The management device 11 can implement the beam coverage management method of this application embodiment in various network devices 12. For example, the network device 12 can be a 5G base station, a macro base station, a micro base station, etc., and this application embodiment does not limit the specific type of network device 12.
[0038] In different application scenarios, the management device 11 and the network device 12 can be independent devices or integrated into the same device. This application embodiment does not specifically limit this.
[0039] When management device 11 and network device 12 are integrated into the same device, the data transmission method between management device 11 and network device 12 is the same as the data transmission between modules within the device. In this case, the data transmission process between the two is the same as the data transmission process between management device 11 and network device 12 when they are independent of each other.
[0040] In the following embodiments provided in this application, the management device 11 and the network device 12 are described as being configured independently of each other.
[0041] Figure 3 This is a flowchart illustrating a beam coverage management method according to some exemplary embodiments. In some embodiments, the above-described beam coverage management method can be applied to, for example... Figure 1 The management devices and network equipment shown can also be applied to other similar devices.
[0042] like Figure 3 As shown, the beam coverage management method provided in this application includes the following steps S201-S203.
[0043] S201, The management device obtains the coverage requirement information of the target cell.
[0044] Among them, the coverage demand information is used to reflect the types of coverage scenarios included in the target cell and the number of each type of coverage scenario.
[0045] As one possible implementation, the management device determines the coverage area of the target cell and obtains coverage demand information within that coverage area.
[0046] It should be noted that the target cell can be any cell in the wireless communication system. The coverage area of a cell is related to its actual operating parameters (cell orientation, base station altitude, antenna downtilt angle, etc.).
[0047] like Figure 4 As shown, the coverage area of a cell can be simplified to a sector-shaped area on a two-dimensional plane. With the cell's azimuth angle as the center and r = min(2km, d) as the coverage radius (2km is taken into account the coverage limitations of the 5G network, and d is 2 / 3 of the distance between the nearest physical site and the cell within ±60 degrees of the cell's coverage direction), the management device can use the sector within the azimuth angle ±60 degrees as the cell's coverage area.
[0048] In some embodiments, the management device can obtain the scene types of all buildings within the coverage area from a preset electronic map database and determine the quantity of each scene type to obtain coverage requirement information.
[0049] It should be noted that the electronic map database stores the scene types corresponding to each building.
[0050] Optionally, you can refer to Table 1 for the classification principles of building scene types.
[0051] Table 1
[0052] As shown in Table 1, buildings with 15 or more floors are classified as high-rise buildings, buildings with 8-14 floors are classified as mid-rise buildings, buildings with 1-7 floors are classified as low-rise buildings, buildings with park or square features are classified as open spaces, and buildings with main road features are classified as roads.
[0053] After the management device obtains the scene type of each building, it can count the number of each scene type. For example, if there is 1 high-rise building, 2 mid-rise buildings, 10 low-rise buildings and 1 road within the coverage area of the target community, the coverage requirement information obtained is: {high-rise (1) & mid-rise (2) & low-rise (10) & road (1)}.
[0054] S202. If a target scenario type exists in the coverage requirement information, the management device configures the first carrier based on the first configuration strategy so that the first carrier covers the target scenario type.
[0055] Among them, the degree of matching between the first configuration strategy and the target scenario type is greater than or equal to the first preset threshold.
[0056] As one possible implementation, after obtaining the coverage requirement information, the management device determines whether a target scenario type exists in the coverage requirement information. If a target scenario type exists in the coverage requirement information, the management device configures a first carrier based on a first configuration strategy to ensure that the first carrier covers the target scenario type.
[0057] It should be noted that the target scenario type is a scenario type pre-set by the operations and maintenance personnel. For example, the target scenario type could be high-rise buildings.
[0058] The first carrier can be any channel carrier in the wireless communication system. For example, the first carrier can be a 3.5 GHz frequency band carrier in a 5G network.
[0059] The first configuration strategy can be pre-set by maintenance personnel or determined by the management device.
[0060] For example, the first configuration strategy corresponds to specific horizontal beamwidths and vertical beamwidths. The management device can refer to the horizontal and vertical beamwidths corresponding to the first configuration strategy to set the beamwidth of the first carrier so that the first carrier covers the target scene type.
[0061] In practical applications, there are 6 commonly used beam configuration strategies, as shown in Table 2.
[0062] Table 2
[0063] One configuration strategy corresponds to one horizontal beamwidth and one vertical beamwidth.
[0064] In related technologies, the beam configuration for each cell and multiple carrier frequencies basically adopts SCENARIO_0 (S0 for short), which cannot meet the coverage requirements of various scenarios. For example... Figure 5 As shown, even with the S0 beam configuration, setting the horizontal beamwidth to 105° and the vertical beamwidth to 6°, some areas still remain uncovered. Figure 5 (For areas above the 15th floor). If SCENARIO_13 (abbreviated as S13) is used, the increased vertical beamwidth allows the beam to completely cover high-rise scenes.
[0065] Therefore, through testing and performance statistics, the preferred beam configurations for various scenarios in this application embodiment are determined as shown in Table 3.
[0066] Table 3
[0067] To determine the beams for mixed scenarios, this embodiment assigns a score to each type of beam configuration according to priority for each type of scenario, as shown in Table 4.
[0068] Table 4
[0069] In some embodiments, to obtain the first configuration strategy, the management device can acquire configuration strategy information corresponding to each coverage scenario type. This configuration strategy information includes multiple preset configuration strategies; the configuration strategy information reflects the matching degree of each preset configuration strategy under different coverage scenario types. Further, based on the configuration strategy information, the management device determines the first configuration strategy from the multiple preset configuration strategies.
[0070] For example, the configuration strategy information can be the content included in Table 4. Multiple preset configuration strategies can be S0, S3, S6, S8, S12, and S13 in Table 4, and the matching degree can be the score in Table 4. When the target scenario type is high-rise, the first preset threshold can be set to 5; therefore, the management device can determine S13 as the first configuration strategy.
[0071] S203. The management device configures the second carrier based on the second configuration strategy so that the second carrier covers non-target scenario types in the target cell.
[0072] Among them, the degree of matching between the second configuration strategy and the coverage requirement sub-information is greater than or equal to the second preset threshold; the coverage requirement sub-information is used to reflect the non-target scenario types in the target cell and the number of each non-target scenario type; the first carrier and the second carrier have different frequency bands.
[0073] It should be noted that the second carrier can be a carrier of any channel in the wireless communication system. For example, the second carrier can be a carrier of the 3.4GHz band in a 5G network. Non-target scenario types refer to scenario types in the target cell other than the target scenario type.
[0074] For example, the second configuration strategy corresponds to specific horizontal beamwidths and vertical beamwidths. The management device can refer to the horizontal and vertical beamwidths corresponding to the second configuration strategy to set the beamwidth of the second carrier so that the second carrier covers the target scene type.
[0075] The second configuration strategy can be pre-set by maintenance personnel or determined by the management device.
[0076] In some embodiments, to obtain a second configuration strategy, the management device can acquire the matching degree between a preset configuration strategy and each non-target scenario type, resulting in multiple matching degrees. The management device determines the overall matching degree of the preset configuration strategy based on the multiple matching degrees and the number of each non-target scenario type, thus obtaining the overall matching degree of the multiple preset configuration strategies. Further, the management device determines the preset configuration strategy with the highest overall matching degree among the multiple preset configuration strategies as the second configuration strategy.
[0077] Optionally, for any non-target scenario type, the management device determines the product between the degree of matching between the preset configuration strategy and the non-target scenario type and the number of non-target scenario types, resulting in multiple products; the management device performs weighted processing on the multiple products to obtain the comprehensive degree of matching of the preset configuration strategy.
[0078] For example, referring to the determination method of the second configuration strategy mentioned above, the following scoring formula can be configured: Formula 1 Where S(i) is the score of configuration policy with configuration policy name i, and i can be S0, S3, S6, S8, S12, or S13 in Table 2. n is the scenario number, for example, n can be 1-6 in Table 4. N(n) is the number of scenarios n in the target cell. P(i)(n) is the score of configuration policy i in scenario n.
[0079] In practical applications, the management device can calculate the score corresponding to each preset configuration strategy according to the above formula, and use the score as the overall matching degree. Furthermore, the management device determines the preset configuration strategy with the highest score as the second configuration strategy.
[0080] The technical solution provided in this application provides at least the following beneficial effects: The management device acquires coverage requirement information of the target cell to obtain the coverage scene types included in the target cell and the quantity of each coverage scene type. If a target scene type exists in the coverage requirement information, the management device configures a first carrier based on a first configuration strategy to ensure the first carrier covers the target scene type; the matching degree between the first configuration strategy and the target scene type is greater than or equal to a first preset threshold. Further, the management device configures a second carrier based on a second configuration strategy to ensure the second carrier covers non-target scene types in the target cell; the matching degree between the second configuration strategy and the coverage requirement sub-information is greater than or equal to a second preset threshold; the coverage requirement sub-information reflects the non-target scene types in the target cell and the quantity of each non-target scene type; the first carrier and the second carrier operate in different frequency bands. In this way, this application not only matches different carriers with different scene types within the coverage area but also configures different beam configuration strategies for different carriers according to the differences in coverage scene types, making the configuration of each carrier more consistent with the needs of the coverage scene, thereby improving the overall coverage quality of the cell.
[0081] In one design, to adapt to the coverage requirements of various scenarios, such as Figure 6 As shown, when the target scenario type is not present in the coverage requirement information, the management device determines the coverage scenario type with the highest frequency in the coverage requirement information, thus obtaining the key coverage scenario type. Further, based on the configuration strategy information and the key coverage scenario type, the management device determines a third configuration strategy and configures a third carrier based on the third configuration strategy to ensure that the third carrier covers the key coverage scenario type. The third configuration strategy is the configuration strategy with the highest degree of matching between multiple preset configuration strategies and the key coverage scenario type.
[0082] The following uses the first sector of a 5G site (School A) as an example to illustrate the beam coverage management method of this application embodiment. Figure 7 As shown, the station is 29 meters high and 360 meters away from the nearest station (Community B). It is configured with dual carriers (including the first carrier F1: 3.4 GHz and the second carrier F2: 3.5 GHz). The first sector can be any sector corresponding to the station, for example, the first sector can be within a range of ±60 degrees.
[0083] Option 1: Use configuration strategy S0, with a vertical half-power angle of 6 degrees (i.e., vertical beamwidth). Define coverage radius = 360. 2 / 3 = 240m, station height 29 meters. Based on trigonometric formulas, the management device calculates that the downtilt angle for this sector is set to 10 degrees. Therefore, when performing beam coverage, the management device can set the operating parameters of the F1 / F2 carriers to: configuration strategy S0, downtilt angle 10 degrees.
[0084] Option 2: The management device obtains the scene type and quantity within the sector, see Table 5.
[0085] Table 5
[0086] As shown in Table 5, there are high-rise buildings in this area. Therefore, according to the configuration strategy selection scheme of this application embodiment (refer to Table 3), the management device selects configuration strategy S13 to match the high-rise scene. Furthermore, assuming the site is 200 meters away from the high-rise scene (i.e., the building corresponding to the high-rise scene type), the building height is 94 meters, and the site height is 29 meters, and the beam vertical half-power angle of S13 is 25 degrees, the management device can calculate and determine the antenna downtilt angle to be -6 degrees based on trigonometric function formulas. That is, the management device can set the F2 carrier's operating parameters to: configuration strategy S13, downtilt angle -6 degrees.
[0087] For the remaining scenarios, the management device calculates the configuration strategy score based on the scenario set according to Formula 1, as shown in Table 6. It should be noted that since high-level scenarios have been configured separately, they are not included in the configuration strategy score for the remaining scenarios.
[0088] Table 6
[0089] As shown in Table 6, S6 received the highest score, and the management device selected S6 to match the remaining scenarios. Furthermore, assuming the site is 240 meters from one of the remaining scenarios, the management device can similarly calculate using trigonometric formulas to determine the antenna downtilt angle to be 12 degrees. That is, the management device can set the F1 carrier's operating parameters to: configuration strategy S6, downtilt angle 12 degrees.
