[0080] Figure 1 Flowchart of a beam coverage method according to an embodiment of the application; refer to Figure 1 An embodiment of the application provides a beam coverage method, which can include:
[0081] Step 110: adjusting beam coverage parameters of a current beam layer according to a UE (User Equipment, also known as terminal) concentration position in a beam coverage range of the current beam layer, to determine a maximum ratio of UEs satisfying a preset condition in the beam coverage range;
[0082] Step 120: in a case where the maximum ratio is less than a target ratio, moving a preset number of beams in an adjacent beam layer to the current beam layer;
[0083] The preset condition includes that a RSRP (Reference Signal Receiving Power) of the UE is greater than or equal to a threshold value.
[0084] The preset number corresponds to an adjustable beam weight value of the adjacent beam layer, and the adjustable beam weight value is less than or equal to an allocated beam weight value of the adjacent beam layer.
[0085] It should be noted that the execution subject of the above method can be a network device, such as a base station, etc. The following will take the network device executing the above method as an example to explain the technical solution of the application in detail.
[0086] Firstly, the network device can adjust the beam coverage parameters of the current beam layer according to the UE concentration position in the beam coverage range of the current beam layer, to determine the maximum ratio of UEs satisfying the preset condition in the beam coverage range.
[0087] The beam coverage range refers to the range that can be covered by the beams of the current beam layer. The UE concentration position refers to the region with the maximum UE density in the beam coverage range; for example, if the beam coverage range is divided according to unit area, the UE concentration position can be the region corresponding to the unit area with the maximum UE density. The UE concentration position can also refer to the region in the beam coverage range with a UE density exceeding a certain threshold value.
[0088] After determining the UE concentration position, the network device can adjust the beam coverage parameters of the current beam layer based on the UE concentration position, and obtain the ratio of UEs with RSRP greater than or equal to the threshold value to all UEs in the beam coverage range after each adjustment, and then take the maximum value in the multiple ratios as the maximum ratio of UEs satisfying the preset condition.
[0089] The RSRP of all UEs in the beam coverage range can be obtained by the MR (Measurement Report) mode after each adjustment, and the number of UEs whose RSRP is greater than or equal to a threshold value is screened out, so as to obtain the ratio of UEs satisfying the preset condition. The size of the threshold value can be adjusted according to actual conditions, and the embodiments of the present application do not make specific limitations thereto.
[0090] After determining the maximum ratio of UEs satisfying the preset condition in the beam coverage range, the network device compares the maximum ratio with a target ratio. The size of the target ratio can be, for example, 95%, and the specific size thereof can be adjusted according to actual conditions, and the embodiments of the present application do not make specific limitations thereto.
[0091] If the maximum ratio is greater than or equal to the target ratio, it means that for the beam layer, most of the UEs in the beam coverage range have been covered, and the signal strength received by the UEs meets the requirements and can satisfy the use demand of the users in the beam coverage range, so it is not necessary to adjust the beams of the beam layer.
[0092] If the maximum ratio is less than the target ratio, it means that for the beam layer, a considerable part of the UEs in the beam coverage range have not been covered, or although most of the UEs in the beam coverage range have been covered, the signal strength received by the UEs is not enough to meet the use demand of the users in the beam coverage range, so the beams of the beam layer need to be adjusted.
[0093] Therefore, in the case where the maximum ratio is less than the target ratio, the network device moves a preset number of beams in the adjacent beam layer to the current beam layer.
[0094] Taking the case where the number of beams is 8, the beams are divided into 4 layers, the current beam layer is the 2nd layer, and the weight distribution of each beam layer is 5+1+1+1 (5 beams are configured in the 1st layer, and 1 beam is configured in the 2nd layer to the 4th layer) as an example:
[0095] When the maximum ratio of UEs satisfying the preset condition in the beam coverage range of the 2nd layer is less than the target ratio, the network device can move a preset number of beams, for example, 1, of the 5 beams in the 1st layer to the 2nd layer, that is, the weight distribution of each beam layer is changed from the adjusted 5+1+1+1 to the adjusted 4+2+1+1.
[0096] It should be noted that the preset quantity corresponds to the adjustable beam weight of the first layer, and the adjustable beam weight can be 1. For a configuration in which the total number of beams is 8 and the weight distribution of each beam layer is 5+1+1+1, the adjustable beam weight 1 corresponds to one beam. For a configuration in which the total number of beams is 8 and the weight distribution of each beam layer is 2+1+1, the adjustable beam weight 1 can correspond to 2 beams, and the adjustable beam weight 0.5 can correspond to 1 beam. The size of the adjustable beam weight can be adjusted according to actual conditions, and the embodiments of the present application do not make specific limitations thereto.
[0097] The beam coverage method provided by the embodiments of the present application can ensure that the adjustment of the beam is adjusted according to actual needs, thereby overcoming the defect of unreasonable beam coverage in the prior art, and improving the quality of communication and resource utilization efficiency.
[0098] In one embodiment, step 110 can include:
[0099] Step 1101, determining the location of the UE set by E-CID (Enhanced Cell-ID) positioning;
[0100] Step 1102, adjusting the azimuth angle and / or downtilt angle of the beam of the current beam layer based on the step length and the adjustment period according to the location of the UE set;
[0101] Step 1103, after each adjustment, determining the ratio of the UE satisfying the preset condition in the beam coverage range, and determining the maximum ratio according to each ratio.
[0102] It should be noted that E-CID positioning includes AOA (Angle of Arrival) technology and TA (Timing Advance) technology.
[0103] The principle of AOA is mainly to measure the angle of arrival of the signal between the MS (Mobile Station) and the network device. The ray formed with the network device as the starting point must pass through the MS, and the intersection of the two rays is the position of the MS. The AOA measurement method can determine the position of the MS only with two network devices, and the principle diagram is as shown in FIG. 1. In FIG. 1, BS1 and BS2 represent network devices, and α1 and α2 represent the angle of arrival. Figure 2 Figure 2
[0104] TA principle: signal transmission in space is delayed, if the MS moves away from the network device during the call, the signal from the network device will be "later and later" to reach the MS; at the same time, the MS signal will also be "later and later" to reach the network device. Too long delay will cause the network device to receive the signal of a certain MS in the time slot and the network device to receive the signal of the next other MS in the time slot, causing inter-code interference. Therefore, during the call, the MS sends the MR header to the network device carrying the time delay value measured by the MS, and the network device must monitor the time of the call arrival, and send instructions to the MS on the downlink channel at a frequency of 480ms once, instructing the MS to send in advance. The time is TA.
[0105] E-CID is a combination of AOA technology and TA technology, which determines the angle relationship between UE and base station through AOA, and estimates the distance between UE and base station through TA, so as to obtain the specific position of UE. The principle diagram of E-CID positioning is shown in Figure 3
[0106] After determining the distribution of each UE in the coverage range of the current beam layer of the network device through E-CID positioning, the network device can determine the centralized position of the UE.
[0107] Then, the network device can align the normal line of the azimuth angle and / or the downtilt angle (beam coverage parameter) of the current beam layer beam to the center of the UE centralized position, and increase or decrease the azimuth angle and / or the downtilt angle by an adjustment step in an adjustment period.
[0108] The adjustment step can be, for example, 10°, 5°, 1°, etc.; the adjustment period can be, for example, 5min, 10min, etc. The specific size of the adjustment step and the adjustment period can be adjusted according to actual conditions, and the present application embodiment does not limit this.
[0109] The network device will determine the ratio of the UE satisfying the preset condition in the coverage range after each adjustment, and record it. After a certain number of adjustments, for example, 10 times, or after a certain length of time, for example, 1h, the network device will stop adjusting, and the maximum value of the recorded ratios will be taken as the maximum ratio of the UE satisfying the preset condition in the coverage range.
[0110] The beam coverage method provided by the present application embodiment can accurately determine the best coverage effect that each beam layer can achieve under the current beam weight configuration, by selecting the maximum value from the ratios corresponding to different beam parameters as the maximum ratio of the UE satisfying the preset condition in the final beam coverage range, so as to ensure the rationality of the final beam weight adjustment.
[0111] After step 1103, the beam coverage method provided by the embodiment of the present application can further include:
[0112] The azimuth angle and / or the downtilt angle corresponding to the maximum ratio is taken as the azimuth angle and / or the downtilt angle of the beam of the final current beam layer.
[0113] It can be understood that when the ratio of the UEs satisfying the preset condition in the beam coverage range is maximum, it indicates that the beam coverage effect at this time is the best, and therefore, the azimuth angle and / or the downtilt angle corresponding to the maximum ratio is taken as the azimuth angle and / or the downtilt angle of the beam of the final current beam layer, which can guarantee the beam coverage effect of the current beam layer, thereby improving the communication quality.
[0114] In one embodiment, after step 1103, the beam coverage method provided by the embodiment of the present application can further include:
[0115] Step 1104, performing first convergence on the horizontal lobe angle and / or the vertical lobe angle of the beam of the current beam layer based on a first convergence step and a first convergence period;
[0116] Step 1105, determining the average RSRP of the UEs satisfying the preset condition in the beam coverage range after each first convergence.
[0117] Step 1106, in the case where the average RSRP becomes smaller, performing second convergence on the horizontal lobe angle and / or the vertical lobe angle before the first convergence based on a second convergence step and a second convergence period.
[0118] The network device can perform the first convergence on the horizontal lobe angle and / or the vertical lobe angle of the beam of the current beam layer based on the first convergence step, for example, 5°, and the first convergence period, for example, 15 minutes, that is, the horizontal lobe angle and / or the vertical lobe angle is converged by 5° within the first convergence period of 15 minutes. The specific size of the first convergence step and the first convergence period can be adjusted according to actual conditions, and the embodiment of the present application does not limit this.
[0119] After each first convergence, the network device determines the average RSRP of the UEs satisfying the preset condition in the beam coverage range.
[0120] If the average RSRP does not become smaller, it indicates that the first convergence does not affect the coverage effect of the beam of the current beam layer in the beam coverage range, and the RSRP can continue to be converged.
[0121] If the average RSRP becomes smaller, it indicates that the coverage effect of the beam of the current beam layer in the beam coverage range is affected after the current first convergence.
[0122] Therefore, the network device reverts the horizontal lobe angle and / or the vertical lobe angle of the beam to a state before the first convergence, and performs a second convergence on the horizontal lobe angle and / or the vertical lobe angle before the first convergence based on a second convergence step, for example, 1°, and a second convergence period, for example, 15 minutes, that is, the horizontal lobe angle and / or the vertical lobe angle is converged by 1° within the second convergence period of 15 minutes.
[0123] The second convergence step is smaller than the first convergence step, and specific sizes of the second convergence step and the second convergence period can be adjusted according to actual conditions, which are not limited by the embodiments of the application.
[0124] It should be noted that the first convergence can be a coarse convergence on the horizontal lobe angle and / or the vertical lobe angle of the beam, and the second convergence can be a fine convergence on the horizontal lobe angle and / or the vertical lobe angle of the beam. Therefore, in general, the second convergence step is smaller than the first convergence step.
[0125] The beam coverage method provided by the embodiments of the application can converge the horizontal lobe angle and / or the vertical lobe angle of the beam of the current beam layer without affecting the beam coverage effect, so as to make the angle of the beam coverage smaller, concentrate the energy of the beam, improve the signal strength, and improve the communication quality.
[0126] After step 1106, the beam coverage method provided by the embodiments of the application can further include:
[0127] After each second convergence, the average RSRP is determined, and the maximum average RSRP is determined according to each average RSRP;
[0128] The horizontal lobe angle and / or the vertical lobe angle corresponding to the maximum average RSRP is taken as the final horizontal lobe angle and / or the vertical lobe angle of the beam of the current beam layer.
[0129] The network device determines the average RSRP of the UE satisfying the preset condition in the beam coverage range after each second convergence, and records. After a certain number of second convergences, for example, 10 times, or after a converging time period, for example, 1h, the network device stops the second convergence, and takes the maximum value in the recorded average RSRPs as the maximum average RSRP of the UE satisfying the preset condition in the beam coverage range.
[0130] It should be noted that when the average RSRP of the UE satisfying the preset condition in the beam coverage range is maximum, it indicates that the beam coverage intensity at this time is maximum, and therefore, the horizontal lobe angle and / or the vertical lobe angle corresponding to the maximum average RSRP are taken as the horizontal lobe angle and / or the vertical lobe angle of the beam of the final current beam layer, which can ensure that the beam coverage intensity of the current beam layer is maximum, thereby improving the communication quality as much as possible.
[0131] In one embodiment, before step 110, the beam coverage method provided by the embodiment of the present application can further include:
[0132] In step 100, according to the maximum building height of the target area of the beam coverage, the number of beam layers and the initial beam weight of each beam layer are determined based on the preset correspondence between the maximum building height and the number of beam layers.
[0133] The preset correspondence between the maximum building height and the number of beam layers can be as shown in Table 3.
[0134] Table 3: Preset correspondence between maximum building height and number of beam layers
[0135] Maximum building height Vertical layering Width proportion Antenna sub-beam configuration Horizontal lobe width per layer 85-100m 4 75% 4+2+1+1 65+65+65+65 85-100m 4 50% 4+2+1+1 65+45+45+45 85-100m 4 30% 5+1+1+1 65+30+30+30 60-65m 3 75% 4+2+2 65+65+65 60-65m 3 50% 4+2+2 65+45+45 60-65m 3 30% 6+1+1 65+30+30 40-45m 2 75% 4+4 65+65 40-45m 2 50% 6+2 65+45 40-45m 2 30% 7+1 65+30 30m 1 100% 8 65
[0136] When determining the initial configuration of the beam, the network device can first only consider dividing the beam into several beam layers. When the maximum building height of the target area of the beam coverage is determined, the network device can correspondingly select the initial beam configuration from Table 3 by default. For example, when the maximum building height is 85-100m, the network device can select the beam configuration of 5+1+1+1; when the maximum building height is 60-65m, the network device can select the beam configuration of 6+1+1; and when the maximum building height is 40-45m, the network device can select the beam configuration of 7+1.
[0137] After determining the number of beam layers and the initial beam weight of each beam layer, the network device can adjust the beam coverage according to the method provided by each method embodiment.
[0138] It should be noted that before step 100, the target area of the beam coverage and the site position and height also need to be determined:
[0139] The range to be covered is obtained through planning and site exploration;
[0140] The horizontal direction of the coverage and the horizontal width of the coverage are obtained through measurement;
[0141] If high-rise buildings need to be covered, the height of the high-rise buildings is obtained through measurement or estimation;
[0142] The horizontal distance of the site and the coverage target is obtained by measurement, including the nearest distance and the farthest distance;
[0143] The height of the site is obtained by measurement, and the height difference between the site and the coverage target is calculated.
[0144] After step 100, the network device needs to determine the horizontal lobe angle, azimuth angle, vertical lobe angle and downtilt angle of each beam according to the above parameters.
[0145] Specifically, the network device can calculate the horizontal lobe angle and azimuth angle of each beam according to the horizontal distance (including the nearest distance and the farthest distance), horizontal direction and horizontal width, and calculate the vertical lobe angle and downtilt angle of each beam according to the height of the highest building, the horizontal distance (including the nearest distance and the farthest distance) and the height difference between the site and the coverage target.
[0146] In one embodiment, after step 120, the beam coverage method provided by the embodiments of the present application can further include:
[0147] If the maximum ratio is still less than the target ratio after moving a preset number of beams in the adjacent beam layer to the current beam layer, the beam layers are configured according to the closest beam coverage configuration scheme;
[0148] The closest beam coverage configuration scheme satisfies any one of the following:
[0149] The number of beam layers with the maximum ratio greater than or equal to the target ratio is the most;
[0150] The number of beam layers with the maximum ratio greater than or equal to the target ratio is the most, and the average value of the maximum ratio of the beam layers is the largest.
[0151] If the maximum ratio of the UE in the beam coverage range of at least one layer of the beam layers is still less than the target ratio after the beam coverage is configured multiple times by the method provided by the above embodiments, the network device can configure the beam layers according to the closest beam coverage configuration scheme after moving a preset number of beams in the adjacent beam layer to the current beam layer.
[0152] Of course, the network device can also directly determine whether the maximum ratio of the UE in the beam coverage range of the current beam layer is less than the target ratio after moving a preset number of beams in the adjacent beam layer to the current beam layer each time; if so, the network device can configure the beam layers according to the closest beam coverage configuration scheme.
[0153] The closest beam coverage configuration scheme is one of the various beam coverage configuration schemes generated in the process of adjusting the beam coverage according to the above embodiments of the present application.
[0154] The closest beam coverage configuration scheme can be the beam coverage configuration scheme in which the number of beam layers with a maximum ratio greater than or equal to the target ratio is the largest.
[0155] For example, in various beam coverage configuration schemes, in the configuration of 4+2+1+1, the number of beam layers with a maximum ratio greater than or equal to the target ratio is 3, while in other configurations, such as 5+1+1+1, 3+2+2+1, etc., the number of beam layers with a maximum ratio greater than or equal to the target ratio is less than 3, then the network device configures each beam layer according to the configuration scheme of 4+2+1+1.
[0156] The closest beam coverage configuration scheme can also be the beam coverage configuration scheme in which the number of beam layers with a maximum ratio greater than or equal to the target ratio is the largest, and the average value of the maximum ratio of the beam layers is the largest.
[0157] For example, in various beam coverage configuration schemes, in the configurations of 4+2+1+1 and 3+2+2+1, the number of beam layers with a maximum ratio greater than or equal to the target ratio is the largest, but in the configuration of 4+2+1+1, the maximum ratio of each beam layer is 96%, 98%, 98%, and 90% respectively, and the average value of the maximum ratio is 95.5%, while in the configuration of 3+2+2+1, the maximum ratio of each beam layer is 94%, 98%, 99%, and 88% respectively, and the average value of the maximum ratio is 94.75%, then the network device configures each beam layer according to the configuration scheme of 4+2+1+1.
[0158] The beam coverage method provided by the embodiments of the present application can ensure reasonable configuration of beam coverage and improve the quality of communication and resource utilization efficiency by configuring each beam layer according to the closest beam coverage configuration scheme in the case where the most ideal beam coverage cannot be achieved (the maximum ratio of a certain beam layer is still less than the target ratio).

In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be geographically separated.
