For ease of understanding, the method for determining carrier aggregation provided by the present application will be specifically introduced below with reference to the accompanying drawings.

Fig. 2 is a flowchart showing a method for determining carrier aggregation according to an exemplary embodiment. The method may be applied to an electronic device, and may also be applied to an apparatus for determining carrier aggregation connected to the electronic device. At the same time, the method can also be applied to devices similar to electronic devices or carrier aggregation determining devices. In the following, the application of the method to electronic equipment is taken as an example to illustrate the method. As shown in FIG. 2, the method for determining carrier aggregation includes the following steps:

S201. The electronic device acquires the subcarrier spacing of the base station, and the target distance between the antenna of the base station and the target position.

As a possible implementation manner, the electronic device acquires engineering data of the base station, where the engineering data includes latitude and longitude coordinates, height, and subcarrier spacing of the base station. Further, the electronic device determines the distance between the target position and the base station in response to the target position coordinates input by the user, and determines the distance between the antenna of the base station and the target based on the determined distance between the target position and the base station, the height of the base station, and Formula 1. The distance between the positions is the target distance. Wherein, the target location is within the coverage area of the base station.

D ² ＝d ² +h ² formula 1

Among them, D is the target distance, d is the distance between the target position and the base station, and h is the height of the base station.

Exemplarily, the target distance, the distance between the target position and the base station, and the height of the base station may be as shown in FIG. 3 .

It should be noted that the subcarrier spacing may specifically be 15 kilohertz (kilo hertz, KHz), 30 KHz, 60 KHz, and 120 KHz.

Exemplarily, the user inputs the coordinates of the target location, and the electronic device determines that the distance between the target location and the base station is 300 meters (meter, m). Further, the electronic device determines that the target distance is 500 m based on the determined distance between the target position and the base station of 300 m, the height of the base station of 400 m, and Formula 1.

As another possible implementation manner, the electronic device acquires engineering data of the base station, where the engineering data includes latitude and longitude coordinates, height, and subcarrier spacing of the base station. The electronic device responds to the target area selected by the user on the electronic map, and determines the distance between the base station and the point on the target area according to the coordinates of the point on the target area. Wherein, the target area is located within the coverage area of the base station.

Further, the electronic device determines that the target position is the point farthest from the base station in the target area, and based on the distance between the target position and the base station, the height of the base station, and formula 1, the distance between the antenna of the base station and the target position is determined as target distance.

Exemplarily, the target area and the location of the base station may be as shown in FIG. 4 .

S202. The electronic device determines a predicted value of signal quality corresponding to the target distance from the first mapping relationship based on the subcarrier spacing of the base station and the target distance.

Wherein, the first mapping relationship is used to indicate the mapping relationship between the coverage radius of the base station and the signal quality in different subcarrier intervals of the base station.

As a possible implementation manner, the electronic device determines a first mapping relationship, where the first mapping relationship includes average values of signal qualities corresponding to different distance ranges in different subcarrier intervals. Further, the electronic device determines a target distance range corresponding to the target distance in the first mapping relationship, and uses an average value of signal quality corresponding to the target distance range as a predicted value of signal quality corresponding to the target distance.

It should be noted that the signal quality may specifically be RSRP, and the unit of the signal quality is decibel relative to one milliwatt (dbm).

Exemplarily, in the case where the subcarrier spacing is 15KHz, the first mapping relationship may be as shown in Table 1 below:

Table 1: First mapping relationship

Distance range(m) Average signal quality (dbm) (0, 78] -69 (78, 156] -72 (156, 234] -79 (234, 312] -82 (312, 390] -87

Exemplarily, in the case where the subcarrier spacing is 30KHz, the first mapping relationship may be as shown in Table 2 below:

Table 2: First mapping relationship

Distance range(m) Average signal quality (dbm) (0,39] -69 (39, 78] -72 (78, 117] -79 (117, 156] -82 (156, 197] -87

Exemplarily, in the case where the subcarrier spacing is 60KHz, the first mapping relationship may be as shown in Table 3 below:

Table 3: First mapping relationship

Distance range(m) Average signal quality (dbm) (0, 19.5] -69 (19.5, 39] -72 (39, 58.5] -79 (58.5, 78] -82 (78, 97.5] -87

Exemplarily, in the case where the subcarrier spacing is 120KHz, the first mapping relationship may be as shown in Table 4 below:

Table 4: First mapping relationship

Distance range(m) Average signal quality (dbm) (0, 10] -69 (10, 20] -72 (20,30] -79 (30, 40] -82 (40, 50] -87

S203. The electronic device determines to perform carrier aggregation on the base station when the predicted value of the signal quality corresponding to the target distance is lower than a preset threshold.

Exemplarily, the preset threshold may be -105dbm.

It can be understood that in the prior art, it is usually judged whether to aggregate TDD and FDD by manually testing RSRP, but this method consumes manpower and material resources. The application obtains the subcarrier spacing of the base station and the target distance between the target position and the base station antenna, and determines the predicted value of the signal quality corresponding to the target distance based on the first mapping relationship. Further, in a case where the predicted value of the signal quality corresponding to the target distance is lower than a preset threshold, it is determined to perform carrier aggregation on the base station. Wherein, the first mapping relationship is used to indicate the mapping relationship between the coverage radius of the base station and the signal quality in different subcarrier intervals of the base station, therefore, the predicted value of the signal quality corresponding to the target distance can be efficiently determined, thereby efficiently judging whether carrier aggregation is required . At the same time, electronic equipment is used to perform carrier aggregation on the base station to improve the efficiency of carrier aggregation.

In some embodiments, in order to determine the first mapping relationship, as shown in FIG. 5, the method for determining carrier aggregation provided in the embodiment of the present application further includes:

S301. The electronic device acquires MR data received by a base station within a preset time period.

Wherein, the MR data includes measurement values and TA values measured by different user equipments to measure the signal quality of the base station.

As a possible implementation, the electronic device acquires MR data reported by different user equipment within a preset period of time. The MR data includes the measurement value of the signal quality of the base station measured by the user equipment, the TA value, the location information of the user equipment, and the user equipment measurement A measure of the signal quality of neighboring base stations.

It should be noted that the unit of the TA value is millisecond (millisecond, ms).

Exemplarily, the MR data may be shown in Table 5 below:

Table 5: MR data

User Device ID TA value (ms) Measured value of signal quality (dbm) 1 1 -68 2 1 -70 3 2 -71 4 2 -73 5 3 -78 6 3 -80 7 4 -81 8 4 -83 9 5 -86 10 5 -88

S302. The electronic device determines a second mapping relationship according to the MR data.

Wherein, the second mapping relationship includes the TA range and the average value of the signal quality. The average value of the signal quality is the average value of the signal quality measurements corresponding to all TA values in the TA range.

As a possible implementation manner, based on the MR data, the electronic device divides the acquired multiple TA values into different TA ranges. Further, the electronic device determines an average value of signal quality measurement values corresponding to all TA values within each TA range.

Exemplarily, the second mapping relationship may be shown in the following table 6:

Table 6: Second mapping relationship

TA range (ms) Average signal quality (dbm) (0,1] -69 (1,2] -72 (2,3] -79 (3, 4] -82 (4,5] -87

S303. The electronic device determines the first mapping relationship according to the second mapping relationship and the distance range corresponding to the TA range of the base station in different subcarrier intervals.

As a possible implementation manner, the electronic device acquires the distance ranges corresponding to the TA ranges in different subcarrier intervals, and determines the first mapping relationship based on the distance ranges corresponding to the TA ranges in different subcarrier intervals and the second mapping relationship.

Exemplarily, in the case where the subcarrier spacing is 15KHz, the distance range corresponding to the TA range can be shown in Table 7 below:

Table 7: Distance range corresponding to TA range

TA range (ms) Distance range(m) (0,1] (0, 78] (1,2] (78, 156] (2,3] (156, 234] (3, 4] (234, 312] (4,5] (312, 390]

Exemplarily, in the case where the subcarrier spacing is 30KHz, the distance range corresponding to the TA range can be shown in Table 8 below:

Table 8: Distance range corresponding to TA range

TA range (ms) Distance range(m) (0,1] (0,39] (1,2] (39, 78] (2,3] (78, 117] (3, 4] (117, 156] (4,5] (156, 197]

Exemplarily, in the case where the subcarrier spacing is 60KHz, the distance range corresponding to the TA range can be shown in Table 9 below:

Table 9: Distance range corresponding to TA range

TA range (ms) Distance range(m) (0,1] (0, 19.5] (1,2] (19.5, 39] (2,3] (39, 58.5] (3, 4] (58.5, 78] (4,5] (78, 97.5]

Exemplarily, in the case where the subcarrier spacing is 120KHz, the distance range corresponding to the TA range can be shown in Table 10 below:

Table 10: Distance range corresponding to TA range

TA range (ms) Distance range(m) (0,1] (0, 10] (1,2] (10, 20] (2,3] (20,30] (3, 4] (30, 40] (4,5] (40, 50]

It can be understood that the second mapping relationship is obtained according to the MR data reported by the user equipment, and the user equipment is a plurality of different user equipments within the coverage of the base station. Therefore, the first mapping relationship obtained based on the second mapping relationship has reliability , so that the accuracy of the predicted value of the signal quality corresponding to the target distance determined based on the first mapping relationship is relatively high. Further, the accuracy of judging whether to perform carrier aggregation based on the predicted value of the signal quality corresponding to the target distance is relatively high.

In some embodiments, in order to determine the target aggregation mode of the base station, as shown in FIG. 6 , the method for determining carrier aggregation provided in the embodiment of the present application further includes:

S401. The electronic device determines a difference between a predicted value of the signal quality corresponding to the target distance and a target value of the signal quality corresponding to the target distance.

As a possible implementation manner, the electronic device determines the difference between the predicted value of the signal quality corresponding to the target distance and the target value of the signal quality corresponding to the target distance in response to the target value of the signal quality corresponding to the target distance input by the user.

Exemplarily, the target value of the signal quality corresponding to the target distance input by the user is -108dbm, and the predicted value of the signal quality corresponding to the target distance determined by the electronic device is -115dbm. Further, the electronic device determines that the difference between the predicted value of the signal quality corresponding to the target distance and the target value of the signal quality corresponding to the target distance is 7dbm.

S402. Based on the difference, the electronic device determines a target aggregation mode of the base station from the third mapping relationship.

Wherein, the third mapping relationship is used to indicate aggregation modes corresponding to different difference ranges. The third mapping relationship includes: the aggregation method corresponding to the first difference range is 2.1GHz frequency band FDD+3.5GHz frequency band TDD aggregation method, the aggregation method corresponding to the second difference value range is 1.8GHz frequency band FDD+3.5GHz frequency band TDD, the third The aggregation method corresponding to the difference range is 900MHz frequency band FDD+3.5GHz frequency band TDD. The minimum value of the second difference range is greater than or equal to the maximum value of the first difference range, and the minimum value of the third difference range is greater than or equal to the maximum value of the second difference range.

As a possible implementation manner, the electronic device determines a difference range in which the difference is located based on the difference, and uses an aggregation mode corresponding to the difference range as a target aggregation mode.

Exemplarily, the third mapping relationship may be shown in the following table 11:

Table 11: The third mapping relationship

Difference range(dbm) aggregation method [3,6] 2.1GHz frequency band FDD+3.5GHz frequency band TDD (6,9] 1.8GHz frequency band FDD+3.5GHz frequency band TDD (9,12] 900MHz frequency band FDD+3.5GHz frequency band TDD

Exemplarily, taking the difference as 5 as an example, the electronic device determines that the aggregation mode of the base station is 2.1 GHz frequency band FDD+3.5 GHz frequency band TDD. Taking the difference as 8dbm as an example, the electronic device determines that the aggregation mode of the base station is 2.1GHz frequency band FDD+3.5GHz frequency band TDD. Taking the difference as 12dbm as an example, the electronic device determines that the aggregation mode of the base station is 2.1GHz frequency band FDD+3.5GHz frequency band TDD.

It should be noted that 2.1GHz is a general term for 2130MHz-2155MHz and 2110MHz-2130MHz, and 2.1GHz is a general term for 2130-2155MHz and 2110-2130MHz.

It can be understood that the larger the difference between the predicted value of the signal quality corresponding to the target distance and the target value of the signal quality corresponding to the target distance, the worse the signal quality corresponding to the target distance is. Since the smaller the frequency band of FDD is, the smaller the penetration loss is. Therefore, the aggregation of FDD with a smaller frequency band and TDD with a frequency band of 3.5 GHz can effectively improve the signal quality corresponding to the target distance.
