[0031] Table 1
[0032] In communication network systems, especially 5G networks, in order to cope with complex environments, there are application scenarios where macro base stations and micro base stations overlap in coverage areas. If the macro and micro base stations are on the same frequency, the interference in the overlapping coverage areas will be more serious, affecting the quality of network services. Figure 1 As shown, when the UE accesses a micro cell, the UE is located within the coverage of both the micro base station signal and the macro base station signal, that is, Figure 1 In the interference area shown, if the central frequency and frequency band range of the macro base station cell and the micro base station cell in the interference area are the same, and the macro cell and the micro cell are inter-station neighboring cells, when the UE performs communication services in the micro cell, the macro cell neighboring cell will interfere with the micro cell, affecting the user's communication quality. In the related art, there are many ways to reduce the interference between macro and micro cells, such as reducing the AAU transmission power of the macro cell to reduce its interference to the micro cell, but the full beam coverage range of the macro cell will also be reduced, which will affect the edge users of the macro cell; that is, in the related art, the method for reducing anti-interference between base stations will affect the communication quality of the entire communication network system. Based on this, the embodiment of the present application provides a method for anti-interference between base stations, an electronic device, a storage medium and a program product, which can reduce the interference between base stations while reducing the impact on the communication quality of the entire communication network system.
[0033] It should be noted that the embodiments of the present application are applied to Figure 2 The communication network system shown includes a micro station device and a macro station device. The micro station device is correspondingly provided with at least one first beam, and the macro station device is correspondingly provided with at least one second beam.
[0034] The micro base station device is configured to obtain a first measurement report within a preset first time period; wherein the first measurement report is reported by a terminal device within the coverage range of each first beam; based on the first measurement report, first interference sample data corresponding to each first beam is counted; based on each first interference sample data, beam adjustment data of the interfered first beam is obtained; and the beam adjustment data is sent to the macro base station device;
[0035] The macro base station device is used to receive beam adjustment data from the micro base station device; obtain a beam adjustment list according to the beam adjustment data, and perform beam adjustment on each second beam in the beam adjustment list.
[0036] For example, Figure 2 As shown in the figure, the dotted line beam is a schematic diagram of the second beam of the macro base station device in the interference area when it is not adjusted, and the solid line beam is a schematic diagram of the beam of the macro base station device after adjustment based on the beam adjustment data of the micro base station device. At this time, the communication quality of the terminal devices located in the original interference area will be improved.
[0037] It should be noted that the first duration can be set manually and obtained based on historical application data. The first duration can be controlled by starting a timer.
[0038] It should be noted that the beam adjustment data can provide the macro base station device with interference data of the second beam that the macro base station device determines to cause interference, so that the beam range of the interfering second beam can be adjusted.
[0039] It is understandable that the micro station devices and macro station devices that interfere with each other may be co-located or not. The method for anti-interference between base stations in the embodiment of the present application can be applied to both co-located micro station devices and macro station devices, and non-co-located micro station devices and macro station devices.
[0040] Therefore, compared with the existing technology that reduces interference by reducing the AAU transmission power of the macro base station, the embodiment of the present application can control the horizontal direction, vertical direction, horizontal coverage width, and vertical coverage width of the macro station's designated sub-beam by controlling the optimized beam, so as to reduce the coverage range of the macro base station, reduce interference, and improve the communication quality of edge cell users.
[0041] In one embodiment, if Figure 3 As shown, the micro station device includes a data acquisition module and a beam resource optimization strategy module; the macro station device includes a beam resource optimization control process module.
[0042] Among them, the data acquisition module is used to execute the data acquisition process to obtain the interference sample data corresponding to each first beam. Exemplarily, the data acquisition process includes: starting the acquisition timer in the micro station device, obtaining the capability information of the terminal device accessing the micro station cell and the location information of the terminal device in real time to perform CSI measurement, so that the micro station device can measure the CSI beam strength of the macro station neighboring area through the terminal device; collecting the MR measurement report (that is, the first measurement report) periodically reported by the terminal device, the MR measurement report includes the cell-level and beam-level RSRP / RSRQ / SINR of the CSI. After the acquisition timer ends, the statistical results of the MR measurement report are passed to the beam resource optimization strategy module.
[0043] Among them, the beam resource optimization strategy module is used to evaluate whether beam optimization is required and obtain beam adjustment data. For example, in one embodiment, the beam resource optimization strategy module executes the following: the micro station device calculates and analyzes the measurement results of the data acquisition module and sends a beam resource adjustment notification to the macro station. Among them, the measurement results include determining whether there is interference between the macro and micro cells; whether it is necessary to start the beam resource optimization control process; and passing the beam adjustment data to the beam resource optimization control process module if optimization is required. In another embodiment, the beam resource optimization strategy module also includes a beam resource optimization evaluation process. Exemplarily, the beam resource optimization evaluation process includes: after entering the evaluation process, starting the acquisition timer and notifying the data acquisition module to execute the data acquisition process again. The MR measurement reports collected twice before and after are processed according to the optimization target and compared to evaluate whether the RSRP or uplink interference meets the optimization expectations.
[0044] The beam resource optimization control process module is used to execute the beam optimization process. For example, the macro station starts the beam optimization timer based on the beam resource adjustment notification and initiates the corresponding CSI-RS beam optimization process within the beam optimization timer, including the beam resource recovery process and the beam resource adjustment process. In some embodiments, after the beam optimization process is completed, the beam resource optimization strategy module is notified to initiate the beam resource optimization evaluation process for optimization evaluation.
[0045] Reference Figure 4 As shown, it can be understood that the method for anti-interference between base stations applied to micro station equipment provided by the present application includes:
[0046] Step S110: Obtain a first measurement report within a preset first time period; wherein the first measurement report is reported by a terminal device within the coverage range of each first beam;
[0047] Step S120: Count first interference sample data corresponding to each first beam according to the first measurement report;
[0048] Step S130: Obtain beam adjustment data of the interfered first beam according to each first interference sample data;
[0049] Step S140: Send beam adjustment data to the macro base station device.
[0050] Therefore, the beam adjustment data of the first wave speed affected by interference on the micro station side is determined by collecting the first measurement report through the micro station device, and the beam adjustment data is sent to the macro station device, so that the macro station device can adjust the beam coverage range based on the beam adjustment data. Compared with the method of adjusting the transmission power to reduce interference in the related technology, the embodiment of the present application reduces interference by adjusting the coverage range of the beam, which can reduce interference between base stations while improving the communication quality of edge cell users. Therefore, compared with the related technology, the embodiment of the present application can reduce interference between base stations while reducing the impact on the communication quality of the entire communication network system.
[0051] It is understandable that the first beam may be the beams in which the micro station device is working, or may be the beam in the interference area where there is signal coverage with the macro station device.
[0052] It is understandable that step S100 can be implemented by starting a collection timer. During the first time period, the terminal device can periodically upload multiple first measurement reports, where T=n*t i (n is the number of times); T is the first time period; t i The reporting period of the terminal device.
[0053] It is understandable that after step S140, steps S110 to S140 may be repeated to continuously optimize the beam.
[0054] It is understandable that the first measurement report is an MR measurement report, including but not limited to cell-level and beam-level RSRP / RSRQ / SINR.
[0055] It should be noted that the first interference sample data represents an interference degree indicator corresponding to the interference to the terminal device in the first beam. The beam adjustment data may include relevant data of the second beam on the macro base station device side that causes interference to the terminal device, such as the macro cell NCGI, the macro cell physical cell ID, and the ID of the macro cell interfering sub-beam (i.e., subBeamIndex).
[0056] It should be noted that step S110 and step S120 complete the data collection process of the micro station device. For example, the first interference sample data includes the number of first interference report samples and the proportion of first interference report samples. Figure 5 As shown in the figure, the data collection process includes the following:
[0057] The micro station device starts the collection timer. Within the first time period T defined by the collection timer, the UE i Periodically report MR measurement reports, T = n*t i (n is the number of times). The micro station device collects the first measurement report. After the T period is reached, that is, after the collection timer period is reached, the collection timer is killed; then the number of first interference report samples n that meet the interference threshold is counted. i And the first interference report sample ratio n ratio .
[0058] It is understood that, in step S130, only when the first interference sample data meets a preset threshold value can the first beam corresponding to the first interference sample data be determined to be an interfering beam, i.e., the second beam interfering with the first beam needs to be adjusted. Beam adjustment data is generated based on the first measurement report corresponding to the interfered first beam, and the interference situation is notified to the macro base station device via the beam adjustment data.
[0059] It is understandable that the first interference sample data includes the number of first interference report samples and the proportion of first interference report samples. Step S120, based on the first measurement report, counting the first interference sample data corresponding to each first beam, includes:
[0060] Counting the total number of samples of the first measurement report corresponding to each first beam;
[0061] Performing interference judgment on each first measurement report of each first beam to obtain a number of first interference report samples corresponding one-to-one to the first beam;
[0062] Divide the number of first interference report samples by the corresponding total number of samples to obtain the ratio of first interference report samples corresponding one-to-one to the first beam.
[0063] Therefore, by calculating the number and proportion of samples of the terminal device being interfered with under each first beam, the degree of interference to the terminal device under each first beam can be better evaluated.
[0064] For example, taking one of the first beams as beam 1 as an example, for beam 1, assuming that there are K first measurement reports of beam 1 collected in the first time period (that is, the total number of samples is K), when the interference threshold is met, the number of first interference report samples is n i , then the first interference report sample ratio n ratio =n i / k. For the total number of samples K, assuming that there are 10 UEs under beam 1 and each UE reports 3 MR reports in the first duration period, the total number of samples K is 3*10=30.
[0065] It is understandable that the first interference sample data includes the number of first interference report samples and the proportion of first interference report samples. Step S130, obtaining beam adjustment data of the interfered first beam according to each first interference sample data, includes:
[0066] For each first interference report sample number, when the first interference report sample number meets the first interference condition and the corresponding first interference report sample ratio is greater than the preset beam interference threshold, determine that the first beam corresponding to the first interference report sample number is the interfered first beam;
[0067] Obtaining beam adjustment data according to a first measurement report of the interfered first beam;
[0068] The first interference condition includes that the number of first interference report samples is greater than a preset beam recovery threshold and the number of first interference report samples is greater than a preset beam maintenance threshold.
[0069] It should be noted that the beam recovery threshold, beam holding threshold value, and beam interference threshold ratio value can be selectively set according to actual needs. In this regard, the embodiments of the present application do not impose too many restrictions.
[0070] The beam recovery threshold is used to indicate whether the interference situation meets expectations and whether beam recovery is required. The beam holding threshold is used to indicate whether the interference situation requires beam adjustment.
[0071] For example, assuming that the beam recovery threshold value B recoveryThr , beam holding threshold B holdThr , beam interference threshold ratio value B sampleRatio , then the number of first interference report samples n i >B recoveryThr And n i >B holdThr ; The first interference report sample ratio n ratio >B sampleRatio Beam adjustment is required.
[0072] It is understandable that the beam adjustment data includes a micro cell global identifier, a macro cell global identifier, a macro cell physical cell identifier, and a macro cell interference sub-beam identifier.
[0073] It should be noted that a unique index identifier can be generated in the macro station device through the micro cell global identifier, the macro cell global identifier, the macro cell physical cell identifier and the macro cell interference sub-beam identifier to identify the second beam for adjustment.
[0074] It is understandable that, after counting the first interference sample data corresponding to each first beam, the method further includes:
[0075] For each first interference report sample number, when the first interference report sample number is greater than the beam recovery threshold and less than or equal to the beam maintenance threshold, it is determined that there is no interference in the first beam corresponding to the first interference report sample number.
[0076] For example, Figure 6 As shown, assuming the beam recovery threshold value B recoveryThr , beam holding threshold B holdThr , then n i >B recoveryThr And n i ≤B holdThr Enter the beam resource maintenance process, the cell configuration management parameters corresponding to the first beam affected by interference remain unchanged, and the process ends.
[0077] It is understandable that, after sending the beam adjustment data to the macro base station device, the method further includes:
[0078] receiving a beam adjustment completion message from a macro base station device; the beam adjustment completion message is generated after beam adjustment is completed according to the beam adjustment data;
[0079] An optimization evaluation is performed on the interfered first beam according to the beam adjustment completion message.
[0080] By performing the optimization evaluation, it can be further determined whether the optimization effect of the second beam adjusted by the macro station device meets expectations. If the expected optimization effect is met, the configuration management parameters of the adjusted second beam are maintained; otherwise, beam resource recovery is required.
[0081] It should be noted that in one embodiment, the optimization evaluation can collect KPI indicator data related to the microcell load for comparison, mainly including whether the KPI indicators such as access, switching, dropped calls, throughput and interference meet expectations. If no KPI indicators are deteriorated, the optimization result is considered reasonable and in line with expectations.
[0082] It is understandable that, in another embodiment, performing optimization evaluation on the interfered first beam according to the beam adjustment completion message includes:
[0083] In response to the beam adjustment completion message, recollect the second measurement reports reported by the terminal devices within the coverage range of each first beam within the first time period;
[0084] Counting second interference sample data corresponding to each first beam according to the second measurement report;
[0085] According to the second interference sample data and the corresponding first interference sample data, it is selected to stop the optimization evaluation or to send a first beam resource recovery request to the macro station device.
[0086] It is understood that for the same first beam, if the second interference sample data shows a degradation in communication quality compared to the corresponding first interference sample data, beam resource recovery is required and a first beam resource recovery request is initiated. Otherwise, it indicates that the current beam adjustment will improve communication quality and the current adjustment parameters are maintained.
[0087] It is understandable that the second interference sample data includes the number of second interference report samples and the proportion of the second interference report samples; the first interference sample data includes the number of first interference report samples and the proportion of first interference report samples, and according to the second interference sample data and the corresponding first interference sample data, selecting to stop the optimization evaluation or sending a first beam resource recovery request to the macro station device includes:
[0088] When the number of second interference report samples meets the second interference condition and the corresponding second interference report sample ratio meets the third interference condition, sending a first beam resource recovery request to the macro station device;
[0089] When the number of second interference report samples meets the fourth interference condition and the corresponding second interference report sample ratio meets the fifth interference condition, stopping the optimization evaluation of the first beam corresponding to the second interference report sample number;
[0090] The second interference condition includes that the second interference report sample number is greater than or equal to the first interference report sample number, and the second interference report sample number is greater than or equal to the beam holding threshold;
[0091] The third interference condition includes that the proportion of the second interference report samples is greater than or equal to the proportion of the first interference report samples, and the proportion of the second interference report samples is greater than or equal to the beam interference threshold proportion value;
[0092] The fourth interference condition includes that the second interference report sample number is less than the first interference report sample number, and the second interference report sample number is less than the beam holding threshold;
[0093] The fifth interference condition includes that the proportion of the second interference report samples is less than the proportion of the first interference report samples, and the proportion of the second interference report samples is less than the beam interference threshold proportion value.
[0094] It should be noted that, in some embodiments, beam recovery may be performed when any one of the third interference conditions or any one of the second interference conditions is met, and this is not limited in the embodiments of the present application.
[0095] For example, taking the third interference condition and the second interference condition as an example, assuming that the number of second interference report samples is n i2 , the second interference report sample ratio n ratio2 , the number of samples of the first interference report is n i , the first interference report sample ratio n ratio , then Figure 7 As shown, the optimization evaluation includes the following steps:
[0096] 1) The micro station device receives the beam resource optimization evaluation process notification (i.e., the beam adjustment completion message) from the macro station device, and the micro station device starts the collection timer to collect the second measurement report reported by the UE under each first beam within the first time period defined by the collection timer. After the first time period ends, the micro station device stops collecting the second measurement report of the terminal device and ends the collection timer.
[0097] 2) Similarly, the number of second interference report samples n that meet the interference threshold is counted i2 And the second interference report sample ratio n ratio2 , compared with the first interference sample data collected for the first time, if the judgment condition is met, the number of interference samples n i2 <n i and sample proportion n ratio2 <n ratio , and the number of interference samples n i2 Satisfy the beam holding threshold value B holdThr , and the sample proportion n ratio2 Less than the beam interference threshold ratio value B sampleRatio At this point, it is considered that the RSRP interference of the service cell accessed by the terminal device has reached the expected level, and the process ends.
[0098] 3) If the interference threshold n i2 ≥n i and sample proportion n ratio2 ≥n ratio , and the number of interference samples n i2 Satisfy the beam holding threshold value B holdThr , and the sample proportion n ratio2 Not less than the beam interference threshold ratio value B sampleRatio , it is considered that the RSRP interference of the serving cell is lower than expected, causing the communication quality to deteriorate, and it is necessary to enter the beam resource recovery process to perform beam recovery.
[0099] It is understandable that, after sending the beam adjustment data to the macro station device, the method further includes at least one of the following:
[0100] Sending a first cell deletion request to the macro base station device, clearing the beam adjustment data corresponding to the beam of the target micro cell in the first cell deletion request, and restoring the default configuration of the target micro cell; wherein the first cell deletion request is used to request the macro base station device to initiate a beam restoration process for the macro neighboring cell of the target micro cell;
[0101] Receive a second cell deletion request sent by the macro station device, and clear the beam adjustment data of the beam corresponding to the target macro cell in the second cell deletion request.
[0102] It should be noted that the target microcell is the microcell to be deleted that triggers the first cell deletion request. The target microcell is assigned at least one first beam. Deleting the cell means logically deleting the first beam, that is, restoring the default configuration of the target microcell means restoring the corresponding first beam to the default configuration.
[0103] For example, Figure 8 As shown in FIG, there is micro-station cell deletion during the beam optimization process, thereby initiating a first cell deletion request. At this time, the processing flow is as follows:
[0104] Upon receiving the microcell deletion notification (i.e., the first cell deletion request), the macro base station determines whether the macro neighboring cell of the target microcell has adjusted its beam. If so, it restores the beam of the macro neighboring cell. The micro base station clears the microcell data, including the beam adjustment data, and restores the default configuration of the target microcell.
[0105] For example, in the process of beam optimization, if there is a macro cell being deleted and the macro cell is performing beam adjustment, then Figure 9 As shown, the processing flow is as follows:
[0106] When the micro base station receives the macro cell deletion notification (i.e., the second cell deletion request), it clears the beam adjustment data corresponding to the target macro cell. When the macro base station determines that its own beam adjustment has occurred, it restores the beam of the target macro cell to the default configuration.
[0107] It is understandable that when the macro base station device and the micro base station device are not co-located; after obtaining the beam adjustment data corresponding to the interfered first beam, the method further includes:
[0108] When the communication link between the macro base station device and the micro base station device is abnormal, the beam adjustment data is cleared.
[0109] For example, for the scenario where the macro and micro stations are not co-located, if the XN link configured between the macro and micro stations as a communication link is abnormal, the micro station device clears all processed data, and the macro station device recovers according to the backup initial data. Figure 10 As shown, the processing flow is as follows:
[0110] When an XN link anomaly is detected, each microcell of the micro base station device clears processing data (including beam adjustment data, etc.), and each macrocell of the macro base station device restores all beams, that is, restores the cell management parameters to those before the beam adjustment.
[0111] It is understandable that referring to Figure 11 As shown, in another embodiment, the present application provides an inter-base interference anti-interference method applied to a macro base station device, where the macro base station device is correspondingly provided with at least one second beam, and the method includes:
[0112] Step S210: receiving beam adjustment data from the micro base station device, where the beam adjustment data is determined based on first interference sample data of multiple first beams corresponding to the micro base station device;
[0113] Step S220: Obtain a beam adjustment list according to the beam adjustment data, and perform beam adjustment on each second beam in the beam adjustment list.
[0114] Therefore, the beam adjustment data of the first wave speed affected by interference on the micro station side is determined by collecting the first measurement report through the micro station device, and the beam adjustment data is sent to the macro station device, so that the macro station device can adjust the beam coverage range based on the beam adjustment data. Compared with the method of adjusting the transmission power to reduce interference in the related technology, the embodiment of the present application reduces interference by adjusting the coverage range of the beam, which can reduce interference between base stations while improving the communication quality of edge cell users. Therefore, compared with the related technology, the embodiment of the present application can reduce interference between base stations while reducing the impact on the overall network quality.
[0115] It should be noted that the second beam is the beam configured by the macro station device.
[0116] It should be noted that the beam adjustment list is used to record the beam information and beam adjustment information of the second beam to be adjusted. The beam information includes beam index information (i.e., key value), where the beam index information can be generated based on the microcell NCGI, macrocell NCGI, macrocell physical cell ID, and macrocell interference subbeam ID (subBeamIndex). The beam adjustment information includes at least one of a horizontal direction of arrival step and a vertical direction of arrival step.
[0117] It should be noted that beam adjustment includes adjustment of horizontal beam angle and vertical beam angle. Figure 12a As shown in FIG, the dotted line portion is the coverage of the second beam after the horizontal beam angle is adjusted in a scenario, such as Figure 12b As shown in FIG, the dotted line portion is the coverage of the second beam after the vertical beam angle is adjusted in one scenario.
[0118] It is understandable that step S220, performing beam adjustment on each second beam in the beam adjustment list, includes:
[0119] For each second beam in the beam adjustment list, obtaining a sub-beam azimuth, a sub-beam tilt, a sub-beam horizontal beamwidth, and a sub-beam vertical beamwidth of the second beam;
[0120] Get the target horizontal direction of arrival step and the target vertical direction of arrival step;
[0121] determining whether a target horizontal direction of arrival step and a target vertical direction of arrival step meet preset adjustment conditions based on the sub-beam azimuth, sub-beam tilt, sub-beam horizontal beamwidth, and sub-beam vertical beamwidth of the second beam;
[0122] When the target horizontal direction of arrival step and the target vertical direction of arrival step meet the preset adjustment conditions, beam adjustment is performed according to the target horizontal direction of arrival step and the target vertical direction of arrival step, otherwise optimization failure data is output.
[0123] It should be noted that the adjustment condition indicates that the shaped beam range of the terminal device obtained according to the target horizontal wave direction stepping and the target vertical wave direction stepping can be covered by the current horizontal beam range interval and vertical beam interval respectively.
[0124] It should be noted that the target horizontal direction of arrival step and the target vertical direction of arrival step can be selectively set with reference to the optional step values in Table 2 below:
[0125]
[0126] Table 2
[0127] It should be noted that the target horizontal direction of arrival step and the target vertical direction of arrival step can refer to any combination of the values in Table 2 above. At this time, according to the above adjustment, if Figure 12a-12b As shown in the figure, assuming that the beam coverage area remains unchanged, as the angle increases, the beam width becomes wider, the beam gain becomes smaller, and the interference of the macro station to the micro station decreases.
[0128] In another embodiment, the target horizontal direction of arrival step and the target vertical direction of arrival step may also be determined using an antenna weight AI optimization algorithm (such as an ant algorithm), thereby enabling more intelligent and reasonable optimization.
[0129] It should be noted that, in one embodiment, when beam adjustment is performed according to the target horizontal direction of arrival step and the target vertical direction of arrival step, H min,max and V min,max The value of H is used to re-judge whether the terminal's shaped beam range falls within the updated H min,max and V min,max Inside.
[0130] It is understandable that judging whether the target horizontal direction of arrival step and the target vertical direction of arrival step meet the preset adjustment conditions based on the sub-beam azimuth, sub-beam tilt, sub-beam horizontal beamwidth, and sub-beam vertical beamwidth of the second beam includes:
[0131] Obtaining a first horizontal beam range interval according to the sub-beam azimuth and the sub-beam horizontal beam width;
[0132] Obtaining a first vertical beam range interval according to the sub-beam tilt angle and the sub-beam vertical beam width;
[0133] According to the sub-beam horizontal beam width and the target horizontal direction of arrival step, a second horizontal beam range interval corresponding to the terminal device covered by the second beam is obtained;
[0134] According to the sub-beam vertical beam width and the target vertical direction of arrival step, a second vertical beam range interval corresponding to the terminal device covered by the second beam is obtained;
[0135] When the second horizontal beam range interval is within the first horizontal beam range interval, and the second vertical beam range interval is within the second vertical beam range interval, it is determined that the target horizontal direction of arrival step and the target vertical direction of arrival step meet a preset adjustment condition.
[0136] For example, if the sub-beam azimuth is the azimuth angle, the sub-beam tilt is the tilt angle, the sub-beam horizontal width is beamWidthH, the sub-beam vertical width is beamWidthV, the target horizontal direction of arrival step is HDOA, and the target vertical direction of arrival step is VDOA, then the first horizontal beam range interval H is min,max =[azimuth-beamWithH / 2,azimuth+beamWithH / 2]; first vertical beam range interval V min,max =[tilt-beamWithV / 2, tilt+beamWithV / 2]; second horizontal beam range interval UE hmin,hmax =[HDOA-beamWithH / 2,HDOA+beamWithH / 2]; Second vertical beam range interval UE vmin,vmax =[VDOA-beamWithV / 2,VDOA+beamWithV / 2]. Then, if condition 1 is satisfied (i.e., UE hmin,hmax ≤H min,max ,UE vmin,vmax ≤V min,max ), it means that the preset adjustment conditions are met.
[0137] It is understandable that, after receiving the beam adjustment data from the micro base station device, the method further includes:
[0138] Starting a first timer;
[0139] Obtaining a beam adjustment list according to the beam adjustment data, and performing beam adjustment on each second beam in the beam adjustment list, including:
[0140] Within a second duration period defined by the first timer, a beam adjustment list is obtained according to the beam adjustment data, and beam adjustment is performed on each second beam in the beam adjustment list.
[0141] By defining the first timer, the beam adjustment process can be better managed. During beam adjustment, when the target horizontal direction of arrival step and the target vertical direction of arrival step do not meet the preset adjustment conditions, the first timer is stopped.
[0142] For example, Figure 13 As shown in Figure 2, the beam adjustment process is as follows:
[0143] First, back up the macro cell configuration, then after receiving the beam adjustment data, start the first timer and calculate the cell beam coverage for each second beam to be adjusted (that is, the above H min,max 、V min,max ) and terminal shaped beam (that is, the above UE hmin,hmax UE vmin,vmax ), when the terminal shaping beam and the cell beam coverage meet condition 1, the cell configuration management parameters are modified according to the Key and Value of the adjustment list. When the terminal shaping beam and the cell beam coverage calculated after the modification still meet the condition that the terminal shaping beam is within the modified cell beam coverage (that is, condition 1 is met) or the timer has not timed out, indicating that the adjustment is valid, the optimized beam ID is recorded, otherwise the beam recovery process is initiated to perform beam recovery.
[0144] It is understandable that after obtaining the beam adjustment list, the method further includes:
[0145] The second beam to be beam-adjusted is used as the target second beam, and management data of the target second beam is backed up to obtain backup management data of the target second beam;
[0146] When the first timer times out and there is a target second beam that has not completed beam adjustment, the beam recovery process is started according to the backup management data of the target second beam that has not completed beam adjustment.
[0147] By backing up the management data before adjustment, it can be further ensured that the data restored during the beam recovery process is the management data before adjustment, further ensuring the accuracy of the configuration.
[0148] It can be understood that, after performing beam adjustment on each second beam in the beam adjustment list, the method further includes:
[0149] receiving a first beam resource recovery request from a micro station device;
[0150] determining a target second beam according to the first beam resource recovery request;
[0151] Initiate the beam recovery process for the target second beam.
[0152] It should be noted that the first beam resource recovery request is triggered when the micro station device optimizes and evaluates the interfered first beam and determines that the communication quality in the overlapping area between the macro station device and the micro station device is degraded after the beam is adjusted.
[0153] It is understood that the beam recovery process includes:
[0154] Deleting the record corresponding to the target second beam in the adjustment list, and performing backup and recovery according to the backup management data corresponding to the target second beam;
[0155] When the adjustment list is not empty, beam adjustment is performed on the remaining second beams in the adjustment list.
[0156] It should be noted that, based on the above, when the beam recovery process is started, one of the following four conditions must be met:
[0157] The first condition is to meet the first interference report sample number n i Less than or equal to the set beam recovery threshold n i ,At this time, it is considered that the interference situation is less than expected, and beam recovery is performed;
[0158] The second condition is that the macro station device starts the first timer, the first timer times out and the beam adjustment is not completed, and the beam recovery is performed;
[0159] The third condition is to recalculate H after the beam resource adjustment process is completed. min,max and V min,max The value does not satisfy UE hmin,hmax ≤H min,max ,UE vmin,vmax ≤V min,max , perform beam recovery;
[0160] The fourth condition is to start the beam resource optimization evaluation process at the micro station equipment, compare the data to see if the interference index deteriorates, and perform beam recovery.
[0161] For example, Figure 14As shown, when there is a second beam that meets one of the above four conditions. According to the sub-beam ID of the second beam in the historical record, the Key of the second beam is searched in the adjustment list, and the adjustment information in the adjustment list is deleted. If the adjustment list is empty after deletion, the backup data of the second beam is restored according to the backup cell configuration management parameters; if the adjustment list is not empty, it means that there are other second beams that still need to adjust the beam resources, then while restoring the backup data of the second beam, the maximum value of the remaining second beam setting step size is recalculated, and the cell configuration management parameters continue to take effect according to the Key in the list, and other processes for the remaining second beams are continued. (If the second beam A meets one of the above four conditions, after it is deleted from the adjustment list, there are second beams B and C in the adjustment list that need to be adjusted, then the step size of the second beams B and C will be recalculated, and the adjustment operation of the second beams B and C will continue. For the second beam A, it will be restored according to the initial backup data).
[0162] It should be noted that, in one embodiment, within the second time period, there is a situation where there are multiple adjustment messages for the same beam information in the adjustment list (that is, one Key corresponds to multiple adjustment information), wherein the adjustment message includes the target horizontal arrival direction step and the target vertical arrival direction step corresponding to the index. Then, when adjusting the second beam corresponding to the beam information, the maximum step value is selected to take effect. For example, for the horizontal arrival direction step, the largest value in the same index is selected. For example, for the vertical arrival direction step, the largest value in the same index is selected for configuration.
[0163] It is understood that the method further comprises at least one of the following:
[0164] Sending a second cell deletion request to the micro base station device, and determining whether to start a beam restoration process according to the second cell deletion request, wherein the second cell deletion request is used to enable the micro base station device to clear beam adjustment data;
[0165] Receive a first cell deletion request sent by the micro station device, and determine whether to start the beam restoration process based on the first cell deletion request.
[0166] It should be noted that when a cell is deleted, the data related to the cell operation needs to be deleted to restore it to the default state, among which the beam adjustment data is one of the data related to the cell operation of the micro station cell.
[0167] For example, Figure 8 As shown, there is micro-station cell deletion during the beam optimization process. The macro station device receives the first cell deletion request sent by the micro station device and performs the beam restoration process.
[0168] For example, Figure 9As shown, during the beam optimization process, a macro cell is deleted. The macro device sends a second cell deletion request to the micro device and starts the beam restoration process if beam adjustment exists.
[0169] It is understandable that when the macro base station device and the micro base station device are not co-located, the method further includes:
[0170] When a communication link between a macro base station device and a micro base station device is abnormal, determining a historically adjusted target beam and initial configuration data of the target beam;
[0171] According to the initial configuration data, the corresponding target beam is configured and restored.
[0172] It should be noted that the initial configuration data is the cell management parameters configured without beam adjustment.
[0173] For example, Figure 10 As shown, in the co-site scenario, taking the communication link between the macro station device and the micro station device as an XN link as an example, when the XN link is abnormal, the second beam of the macro station device that has been historically adjusted is restored; and the beam adjustment data of the micro station device is cleared.
[0174] It should be noted that the first interference sample data is interference data collected before the beam resource adjustment process, and the second interference sample data is interference data obtained during the beam resource optimization and evaluation process.
