Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a carrier power configuration method, apparatus, device, storage medium, and computer program product. Background Technology

[0002] In the development of 5G-Advanced (5GA) networks, carrier aggregation (CA) technology, especially three-carrier aggregation (3CC) technology, has become an important component of 5GA networks by aggregating multiple component carriers (CCs) to support greater bandwidth and higher speeds. In actual deployments, operators often configure cells with different bandwidths (such as 100MHz and 60MHz cells) within the same frequency band to fully utilize spectrum resources and achieve carrier aggregation.

[0003] Currently, in 3CC carrier aggregation scenarios, especially in frequency bands such as n41 and n79, a fixed power configuration strategy is typically adopted. This means allocating 10 / 16 of the AAU power to a 100MHz bandwidth cell and 6 / 16 of the AAU power to a 60MHz bandwidth cell. While this strategy is simple to implement, it has revealed certain limitations in actual network operation: if a cell is already configured with maximum power due to coverage optimization, reducing its power when 3CC is enabled may lead to a shrinking coverage area, thereby affecting the communication experience of edge users. On the other hand, blindly deploying 3CC in areas without high service demand may result in network resource redundancy and reduce overall network efficiency.

[0004] Therefore, there is an urgent need for a configuration method that can dynamically adjust power based on actual coverage performance and business needs, so as to improve network resource utilization efficiency while ensuring user experience. Summary of the Invention

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] To address the problem that existing solutions cannot dynamically adjust carrier power based on actual coverage performance and service requirements, this application provides a carrier power configuration method. The executing entity of the carrier power configuration method provided in this application can be, but is not limited to, at least one of a carrier configuration system, a wireless communication system, and a network service scheduling system.

[0019] For ease of description, the following description uses a carrier configuration system as the execution subject to illustrate the implementation of this method. It should be understood that using a carrier configuration system as the execution subject is merely an illustrative example and should not be construed as a limitation of the method.

[0020] Specifically, the schematic diagram of the specific implementation process of the carrier power configuration method provided in this application is as follows: Figure 1 As shown, the main steps include the following: Step 11: Generate 5G sampling points carrying geographical location information based on the received measurement report (MR) data; It should be noted that, since commercial terminals do not currently support the 5G Minimization of Drive-tests (MDT) function, in order to generate 5G sampling points carrying geographical location information, in this embodiment of the application, latitude and longitude information can be assigned to the 5G sampling points by fusing 4G MDT data and 5G Measurement Report (MR) data.

[0021] In one implementation, step 11 may include: receiving Minimum Drive Test (MDT) data from a 4G network; receiving Measurement Report (MR) data from a 5G network; and associating the MDT data with the MR data to generate 5G sampling points carrying geographic location information.

[0022] Specifically, the carrier configuration system can collect MDT data of the 4G network from the network management system. In this embodiment of the application, the collected 4G network MDT data may include, but is not limited to, the following fields: Evolved NodeB Identifier (eNB ID), Serving Cell RSRP (ScRSRP), Serving Cell Frequency (ScEarfcn), Serving Cell PCI (ScPCI), Neighboring Cell Frequency (NcEarfcn), Neighboring Cell PCI (NcPCI), Neighboring Cell RSRP (NcRSRP), and latitude and longitude information.

[0023] Furthermore, the carrier configuration system can establish a mapping relationship between 4G and 5G cells based on the base station operating parameter table and the 4G / 5G co-location table. Based on timestamps, terminal identifiers, and other information, it can associate 4G MDT data and 5G MR data reported by the same terminal at similar times. Utilizing the precise latitude and longitude information in the 4G MDT data as the geographical location of the associated 5G MR data, it generates 5G sampling points carrying latitude and longitude information.

[0024] Step 12: Based on the geographic location information determined by executing Step 11, determine the geographic grid that matches each of the 5G sampling points in the Geographic Information System (GIS) to obtain a set of geographic grids. Specifically, in this embodiment, the carrier configuration system can match each 5G sampling point carrying geographical location information (e.g., latitude and longitude information) obtained by executing step 11 with a pre-divided geographic grid on a Geographic Information System (GIS) electronic map. For example, the Geohash algorithm can be used to divide the GIS electronic map into several rectangular grids of the same size (e.g., 50m x 50m). Then, for each sampling point, the carrier configuration system can determine the geographic grid corresponding to each 5G sampling point on the GIS electronic map based on its latitude and longitude coordinates, thereby obtaining a geographic grid set containing all sampling points.

[0025] Step 13: Based on the preset three-carrier aggregation 3CC frequency band combination requirements, the geographic grid set is filtered to obtain the first grid set; In one embodiment, the carrier configuration system can filter the geographic grid set by means of: selecting geographic grids in the geographic grid set that meet the preset three-carrier aggregation 3CC band combination requirements, and whose average reference signal received power RSRP is higher than a first threshold and whose number of sampling points is higher than a second threshold, thereby obtaining a first grid set.

[0026] In this embodiment of the application, the preset requirement for the three-carrier aggregation 3CC frequency band combination can be: there are sampling points of at least two of the frequency bands n41, n79 and n28 within the geographic grid, and there are sampling points of two cells with different bandwidths in the n41 or n79 frequency band.

[0027] For example, if three 5G sampling points, n41 (100MHz), n41 (60MHz) and n28 (30MHz), exist simultaneously within a geographic grid, then the geographic grid can be determined to meet the preset three-carrier aggregation 3CC band combination requirements.

[0028] In this embodiment of the application, the carrier configuration system can calculate and determine the frequency information corresponding to the 5G sampling point based on the network collection information corresponding to the 5G sampling point (such as the collection of 5G network standard, frequency band information, physical cell identity (PCI), bandwidth, base station latitude and longitude information, antenna azimuth angle, downtilt angle, etc.).

[0029] Specifically, in the embodiments of this application, the carrier configuration system can calculate the average RSRP value of all sampling points in each frequency band that meets the preset three-carrier aggregation 3CC frequency band combination requirements within each geographic grid, and set a first threshold T0 = -105 dBm and a second threshold T1 = 50, thereby filtering out geographic grids with average RSRP > T0 and total number of sampling points > T1 to obtain the first grid set.

[0030] In this application embodiment, the frequency point information includes the following types: 1. ARFCN (Absolute Radio Frequency Channel Number) is a numbering scheme used to uniquely identify the center of a radio frequency channel in a wireless communication system, rather than directly using a frequency value (such as MHz). The actual center frequency can be calculated from a table or by formula using the ARFCN. In 5G NR, it is called NR-ARFCN (or NARFCN).

[0031] 2. The SSB (Synchronization Signal Block Frequency Point) represents the center frequency location of the synchronization signal block. The SSB is a key signal in 5G NR used for cell search, downlink synchronization, and downlink measurement, and includes the PSS, SSS, and PBCH. Its frequency point is defined by the GSCN (Global Synchronization Channel Number) and must fall on a predefined synchronization raster.

[0032] In this embodiment of the application, the carrier configuration system can determine the frequency point data according to the following method: I. The basic parameters of the n41 frequency band are as follows: Frequency range: 2496-2690 MHz, bandwidth 100 MHz, subcarrier spacing (SCS): 15kHz ~30kHz.

[0033] ARFCN scope: When the subcarrier spacing (SCS) = 15kHz, the ARFCN range is 499200-537999 with a step size of 3.

[0034] When the subcarrier spacing (SCS) is 30kHz, the ARFCN range is 499200-537996 with a step size of 6.

[0035] The relationship between NARFCN and carrier center frequency (FDL) is shown in the following formula [1]: FDL=FDL_low+0.1×(NARFCN-Noffset) [1] Where FDL_low=2496MHz (representing the starting frequency of the n41 band), Noffset=499200 (representing the ARFCN corresponding to the 2496MHz frequency).

[0036] Therefore, ARFCN: 513000 corresponds to a center frequency of 2565 MHz.

[0037] II. Calculation method for SSB frequency point number: 1. Global Synchronization Channel Number (GSCN) and SSB Center Frequency: The GSCN is used to define the possible frequency locations (i.e., synchronization grids) of the SSB. Each GSCN corresponds to a specific SSB frequency point, and the UE searches for cells by scanning the GSCN.

[0038] In this embodiment of the application, the relationship between the GSCN and the SSB center frequency is shown in the following formula [2]: FSS_REF=FSS_Offs+0.03×(NGSCN-NSS_Offs) [2] Where FSS_Offs=2496MHz (starting frequency of the synchronization grid in the n41 band), and NSS_Offs=6312 (representing the GSCN corresponding to the 2496MHz frequency).

[0039] When NGSCN=6312, FSS_REF=2496+0.03×(6312-6312)=2496MHz.

[0040] 2. The relationship between the location of SSB and ARFCN: In the embodiments of this application, the center frequency of the SSB needs to be within the carrier bandwidth and meet the channel grid requirements. For example, the SSB frequency point number 504990 in the n41 band (corresponding to GSCN 6312) has a center frequency of 2496 MHz, which is located at the low end of the carrier and facilitates fast cell search.

[0041] In this embodiment of the application, the carrier configuration system can filter the geographic grid set according to the following method: filter out geographic grids in the geographic grid set that meet the preset three-carrier aggregation 3CC frequency band combination requirements, and whose average reference signal received power RSRP is higher than a first threshold and whose number of sampling points is higher than a second threshold, to obtain a first grid set.

[0042] Step 14: Perform neighbor clustering on the valid rasters in the first raster set obtained by performing step 13 to generate one or more valid raster clusters; It should be noted that since the geographic rasters in the first set of rasters obtained by performing step 13 may be discrete, performing step 14 can aggregate adjacent valid rasters into a continuous area to identify a large range of user hotspot areas.

[0043] In this embodiment, the carrier configuration system calculates the geographic raster information adjacent to each valid raster, and counts the valid rasters that are adjacent and whose number exceeds a threshold T2 as valid raster clusters.

[0044] For example, iterate through each geographic raster in the first raster set H1, using the geographic raster Grid. (i,j) For example, check the Grid (i,j) Are there adjacent grid cells belonging to H1 in the four directions of east, south, west, and north? Assuming a Grid is detected... (i+1,j) Grid (i-1,j) Grid (i,j+1) Grid (i,j-1) Adjacent grid cells Figure 2 As shown, Clustering algorithms (such as depth-based or breadth-based search algorithms) are used to group all interconnected rasters into a single cluster, with a minimum cluster size threshold of 5. Only clusters with 5 or more rasters are retained and defined as valid raster clusters. The resulting valid raster clusters are shown below. Figure 3 As shown.

[0045] Step 15: Obtain the power configuration information of the 5G cell corresponding to each effective grid cluster, and determine whether the 5G cell corresponding to each effective grid cluster is a coverage-limited area based on the power configuration information. In this embodiment of the application, the power configuration information includes: current power configuration information and power headroom (PHR) statistics. The carrier configuration system can obtain these two types of power configuration information using the following methods: 1. Current power configuration information: Based on the measurement report MR data, the current power configuration information is obtained. Specifically, the carrier configuration system can query the AAU model and its current single-channel power configuration value (such as 327, 357, 400, etc.) of all 5G cells covered by the effective grid cluster from the network management system (for example, the three cells serving the effective grid cluster C1: gNB1-n41(100M), gNB1-n41(60M), gNB2-n28). By querying the configuration table, it can determine whether its current power has been configured to the maximum rated power.

[0046] 2. Power Margin PHR Statistics: Based on the measurement report MR data, obtain the power margin PHR value of each sampling point in the effective grid cluster; based on the power margin PHR value, determine the proportion of samples with power margin PHR values ​​lower than 0 in the measurement report MR data, and determine the power margin PHR statistics of the 5G cell corresponding to the effective grid cluster based on the sample proportion.

[0047] Specifically, the carrier configuration system can extract the MR data of these cells within the statistical period and statistically analyze the distribution of UE power headroom (PHR). It then calculates the proportion of samples with PHR values ​​less than 0 for each cell and determines the PHR statistics of the 5G cells corresponding to the effective grid clusters based on this proportion.

[0048] In this embodiment of the application, the carrier configuration system can determine whether the area where the effective grid cluster is located is a coverage-limited area according to the following method: based on the current power configuration information, determine whether there is a 5G cell configured with the maximum rated power in the 5G cell corresponding to the effective grid cluster; when the determination result is yes, determine whether the power margin PHR statistics are lower than a preset third threshold; when the determination result is yes, determine that the 5G cell corresponding to the effective grid cluster is a coverage-limited area; when the determination result is no, determine that the 5G cell corresponding to the effective grid cluster is a coverage-unlimited area.

[0049] Specifically, for any valid grid cluster, if any 5G cell it contains simultaneously meets the following two conditions, then the area is determined to be an area with limited coverage performance: Condition 1: The community has been configured with maximum rated power; Condition 2: The proportion of samples with PHR < 0 in this cell is higher than the fourth threshold N1 (e.g., N1 = 15%).

[0050] Conversely, if the coverage performance is not limited, it is determined to be an area with no coverage limitations.

[0051] Step 16: Based on the judgment result, configure the power of three-carrier aggregation (3CC) for the 5G cell corresponding to each effective grid cluster.

[0052] In this embodiment of the application, depending on whether the 5G cell corresponding to the effective grid cluster is a coverage performance area, the carrier power can be configured according to the following methods: 1. When the judgment result is yes, disable the three-carrier aggregation (3CC) function of the 5G cell corresponding to the effective grid cluster; Specifically, for areas with limited coverage performance, it indicates that the existing network coverage in the area has reached its limit. Enabling 3CC and reducing power will worsen the user experience. Therefore, for cells involved in areas with limited coverage performance, the 3CC carrier aggregation function will not be enabled, and their existing power configuration will remain unchanged.

[0053] 2. When the judgment result is negative, enable the three-carrier aggregation (3CC) function of the 5G cell corresponding to the effective grid cluster, and configure the three-carrier aggregation (3CC) power of the 5G cell.

[0054] For areas with unrestricted coverage, indicating sufficient network coverage margin, 3CC can be enabled. Enable 3CC for the cells involved in this area, and configure power for different cells in the n41 or n79 bands according to their bandwidth ratios. For example, configure 10 / 16 of the total AAU power for a 100MHz bandwidth cell, and 6 / 16 of the total AAU power for a 60MHz bandwidth cell. For cells in other bands such as n28, maintain their existing power configurations.

[0055] The carrier power configuration method provided in this application involves generating 5G sampling points carrying geographical location information based on received measurement report (MR) data during carrier power configuration. Based on the geographical location information, geographic gratings matching each 5G sampling point are determined in a geographic information system (GIS), resulting in a geographic grating set. The geographic grating set is then filtered according to preset three-carrier aggregation (3CC) frequency band combination requirements to obtain a first grating set. The effective gratings in the first grating set are clustered adjacently to generate one or more effective grating clusters. Power configuration information of the 5G cell corresponding to each effective grating cluster is obtained. Based on the power configuration information, it is determined whether the 5G cell corresponding to each effective grating cluster is in a coverage-limited area. Based on the determination result, the power of three-carrier aggregation (3CC) is configured for the 5G cell corresponding to each effective grating cluster. The carrier power configuration method provided in this application, on the one hand, by associating and filtering measurement report (MR) data with GIS gratings, can accurately identify geographical areas that simultaneously meet the multi-carrier aggregation frequency band requirements and have high service density and good coverage. On the other hand, by clustering the selected effective grids into adjacent clusters, continuous effective grid clusters are formed, thereby enabling network performance evaluation and decision-making at the regional level rather than the individual cell level. By judging whether there are coverage limitations in the effective grid clusters, potential risk areas can be effectively identified before multi-carrier aggregation is enabled, preventing the shrinkage of the original cell coverage due to power reconfiguration, and fundamentally ensuring that the service experience of users at the cell edge is not affected.

[0056] In one embodiment, this application also provides a carrier power configuration device to address the problem that existing solutions cannot dynamically adjust carrier power based on actual coverage performance and service requirements. A schematic diagram of the specific structure of this carrier power configuration device is shown below. Figure 4 As shown, it includes: a sampling point generation unit 41, a geographic raster determination unit 42, a first raster set generation unit 43, an effective raster cluster generation unit 44, a coverage performance limited identification unit 45, and a carrier configuration unit 46.

[0057] Among them, the sampling point generation unit 41 is used to generate 5G sampling points carrying geographical location information based on the received measurement report MR data; The geographic raster determination unit 42 is used to determine, based on the geographic location information, the geographic raster that matches each of the 5G sampling points in the geographic information system (GIS) to obtain a geographic raster set. The first grid set generation unit 43 is used to filter the geographic grid set according to the preset three-carrier aggregation 3CC frequency band combination requirements to obtain the first grid set. The effective grid cluster generation unit 44 is used to perform adjacent clustering on the effective grids in the first grid set to generate one or more effective grid clusters. The coverage performance limited identification unit 45 is used to obtain the power configuration information of the 5G cell corresponding to each effective grid cluster, and determine whether the 5G cell corresponding to each effective grid cluster is a coverage performance limited area based on the power configuration information. The carrier configuration unit 46 is used to configure the power of three-carrier aggregation (3CC) for each 5G cell corresponding to the effective grid cluster according to the judgment result.

[0058] In one embodiment, the sampling point generation unit 41 is specifically used for: receiving minimum drive test (MDT) data from a 4G network; receiving measurement report (MR) data from a 5G network; and associating the MDT data with the MR data to generate 5G sampling points carrying geographical location information.

[0059] In one embodiment, the first grid set generation unit 43 is specifically used to: select geographical grids from the geographical grid set that meet the preset three-carrier aggregation 3CC band combination requirements, and whose average reference signal received power RSRP is higher than a first threshold and whose number of sampling points is higher than a second threshold, to obtain the first grid set.

[0060] In one implementation, a preset requirement for the combination of three-carrier aggregation 3CC frequency bands includes: the existence of sampling points of at least two of the frequency bands n41, n79 and n28 within the geographic grid, and the existence of sampling points of two cells with different bandwidths within the n41 or n79 frequency band.

[0061] In one implementation, the power configuration information includes: current power configuration information and power headroom (PHR) statistics. The coverage performance-limited identification unit 45 is specifically configured to: obtain the power headroom (PHR) value of each sampling point in the effective grid cluster based on the measurement report (MR) data; determine the proportion of samples in the measurement report (MR) data where the power headroom (PHR) value is lower than 0 based on the power headroom (PHR) value; determine the power headroom (PHR) statistics of the 5G cell corresponding to the effective grid cluster based on the sample proportion; obtain the current power configuration information based on the measurement report (MR) data; and determine the power configuration information of the 5G cell corresponding to the effective grid cluster based on the power headroom (PHR) statistics and the current power configuration information.

[0062] In one embodiment, the coverage performance limited identification unit 45 is specifically used to: determine, based on the current power configuration information, whether there is a 5G cell configured with maximum rated power among the 5G cells corresponding to the effective grid cluster; when the determination result is yes, determine whether the power margin PHR statistics are lower than a preset third threshold; when the determination result is yes, determine that the 5G cell corresponding to the effective grid cluster is a coverage performance limited area; when the determination result is no, determine that the 5G cell corresponding to the effective grid cluster is a coverage performance unrestricted area.

[0063] In one embodiment, the carrier configuration unit 46 is specifically configured to: when the determination result is yes, disable the three-carrier aggregation (3CC) function of the 5G cell corresponding to the effective grid cluster; when the determination result is no, enable the three-carrier aggregation (3CC) function of the 5G cell corresponding to the effective grid cluster, and configure the three-carrier aggregation (3CC) power of the 5G cell.

[0064] The carrier power configuration apparatus provided in this application, when configuring carrier power, generates 5G sampling points carrying geographical location information based on the received measurement report (MR) data; based on the geographical location information, determines geographical gratings matching each 5G sampling point in a geographic information system (GIS) to obtain a set of geographical gratings; filters the set of geographical gratings according to preset three-carrier aggregation (3CC) frequency band combination requirements to obtain a first set of gratings; performs adjacent clustering on the effective gratings in the first set of gratings to generate one or more effective grating clusters; obtains the power configuration information of the 5G cell corresponding to each effective grating cluster; determines whether the 5G cell corresponding to each effective grating cluster is a coverage-limited area based on the power configuration information; and configures the three-carrier aggregation (3CC) power for the 5G cell corresponding to each effective grating cluster based on the determination result. The carrier power configuration method provided in this application, on the one hand, by associating and filtering the measurement report (MR) data with the GIS gratings, can accurately identify geographical areas that simultaneously meet the multi-carrier aggregation frequency band requirements and have high service density and good coverage. On the other hand, by clustering the selected effective grids into adjacent clusters, continuous effective grid clusters are formed, thereby enabling network performance evaluation and decision-making at the regional level rather than the individual cell level. By judging whether there are coverage limitations in the effective grid clusters, potential risk areas can be effectively identified before multi-carrier aggregation is enabled, preventing the shrinkage of the original cell coverage due to power reconfiguration, and fundamentally ensuring that the service experience of users at the cell edge is not affected.

[0068] The processor reads the corresponding computer program from non-volatile memory into main memory and then executes it, forming a carrier power configuration device at the logical level. The processor executes the program stored in memory and specifically performs the following operations: Based on the received measurement report (MR) data, 5G sampling points carrying geographic location information are generated. Based on the geographic location information, geographic gratings matching each 5G sampling point are determined in a Geographic Information System (GIS), resulting in a geographic grating set. According to preset three-carrier aggregation (3CC) frequency band combination requirements, the geographic grating set is filtered to obtain a first grating set. Neighbor clustering is performed on the effective gratings in the first grating set to generate one or more effective grating clusters. Power configuration information of the 5G cell corresponding to each effective grating cluster is obtained. Based on the power configuration information, it is determined whether the area where each effective grating cluster is located is a coverage-limited area. Based on the determination result, the power of three-carrier aggregation (3CC) is configured for the 5G cell corresponding to each effective grating cluster.
