Figure 2a is a flow diagram illustrating determining a beamforming mode according to some embodiments of the present disclosure. As shown in FIG. 2a, the process of determining the beamforming mode according to the embodiment of the present disclosure includes:

Step S121: Determine intermediate index data according to the monitoring index data of the target area corresponding to the base station.

In some embodiments, the intermediate indicator data includes at least one of the beam interference level of the target area, the required signal coverage depth, the distribution of users, and the proportion of users with preset data packet service requirements.

Wherein, the beam interference degree of the target area is determined according to the interference signal measurement information in the target area. In some embodiments, when the interference signal measurement information in the target area includes the uplink interference signal strength and the signal strength of the base station, the ratio of the uplink interference signal strength and the signal strength of the base station is used as the beam interference degree of the target area. In other embodiments, a Signal to Interference plus Noise Ratio (SINR) is used as an indicator of the beam interference degree of the target area. The larger the SINR, the smaller the signal interference level; the smaller the SINR, the larger the signal interference level.

The required signal coverage depth is determined according to the user location information in the target area, and the user distribution is determined according to the user location information in the target area. In some embodiments, the coverage distance of the signal required by the user is determined according to the location information of multiple users in the target area; the required signal coverage is determined according to the coverage distance of the signal required by the user and the preset coverage distance of the base station signal depth. For example, the ratio of the coverage distance of the signal required by the user to the preset coverage distance of the base station signal is used as the required signal coverage depth. For example, according to the location information of multiple users in the target area, it is determined that the users are generally distributed within a range of 400 meters from the base station. Based on this, it is determined that the coverage distance of the signal required by the user is 400 meters, and the preset coverage distance of the base station signal is 500 meters, from which the required signal coverage depth is calculated to be 0.8.

Among them, the proportion of users with preset data package service requirements is determined according to the service requirements of users in the target area.

In some embodiments, the number of users with preset data packet service requirements in the target area and the total number of users in the target area are counted, and the number of users with preset data packet service requirements in the target area and the total number of users in the target area are calculated. The proportion of users who have preset data package business requirements. Exemplarily, the preset data packet may be a data packet whose data volume is greater than the preset data volume threshold.

Step S122: Determine the target beamforming mode of the base station according to the intermediate index data.

Exemplarily, the target beamforming mode of the base station is determined according to at least one of the beam interference degree of the target area, the required signal coverage depth, user distribution, and the proportion of users with preset data packet service requirements.

In some embodiments, the intermediate indicator data includes the beam interference degree of the target area and the required signal coverage depth, and step S122 includes: the beam interference degree in the target area is greater than or equal to a preset interference threshold, or the required signal When the coverage depth is greater than the preset depth threshold, it is determined that the target beamforming mode of the base station is the first beamforming mode; the beam interference degree in the target area is less than the preset interference threshold, and the required signal coverage depth is less than the preset In the case of the depth threshold, it is determined that the target beamforming mode of the base station is a mode other than the first beamforming mode, wherein the first beamforming mode is a single beamforming mode, and the beam width is larger than that of the other modes. The beam width is narrow.

In other embodiments, the intermediate index data includes the beam interference level of the target area, the required signal coverage depth, user distribution, and the proportion of users with preset data packet service requirements. Step S122 includes steps A1 to A5.

Step A1: Determine whether the beam interference degree of the target area is greater than or equal to the preset interference threshold, or whether the required signal coverage depth is greater than the preset depth threshold.

If the judgment result of step A1 is yes, go to step A2; if the judgement result of step A1 is no, go to step A3.

In other embodiments of the present disclosure, when the degree of beam interference is characterized by SINR, step A1 should be adjusted to: determine whether the SINR of the target area is less than or equal to the preset interference threshold, or whether the required signal coverage depth is greater than the preset depth threshold. If the SINR is less than the preset interference threshold, or the required signal coverage depth is greater than the preset depth threshold, step A2 is performed; otherwise, step A3 is performed.

Step A2: Determine the target beamforming mode of the base station as the first beamforming mode, wherein the first beamforming mode is a single beamforming mode, and the beamwidth is narrower than that of other modes.

Step A3: Determine whether the user distribution satisfies that the dispersion degree in at least one preset direction is greater than or equal to a preset dispersion degree threshold, or whether the proportion of users with preset data packet service requirements is greater than or equal to a preset proportion threshold.

If the judgment result of step A3 is yes, go to step A4; if the judgement result of step A3 is no, go to step A5.

Step A4: Determine that the target beamforming mode is the second beamforming mode, wherein the second beamforming mode is the multi-beamforming mode.

Step A5: Determine that the target beamforming mode is other than the first and second beamforming modes.

In the embodiment of the present disclosure, through the above steps, the target beamforming mode of the base station can be adaptively determined according to the monitoring index data, thereby effectively improving the beamforming capability of the base station, meeting the requirements for the beamforming mode in different service scenarios, and improving mobile Communication network performance and user experience.

Figure 2b is a flow diagram illustrating determining a beamforming mode according to further embodiments of the present disclosure. In Fig. 2b, the detailed flow of step S122 is exemplified. As shown in FIG. 2b, the process of determining the beamforming mode according to the embodiment of the present disclosure includes:

Step S1221: Determine whether the degree of beam interference is greater than or equal to C1.

Wherein, C1 is a preset interference threshold. In step S1221, the beam interference degree in the target area corresponding to the base station is compared with a preset interference threshold. When the beam interference degree is greater than or equal to C1, step S1223 is performed; when the beam interference degree is less than C1, step S1222 is performed.

In the embodiment of the present disclosure, the beam interference degree is the ratio of the strength of the interference signal to the strength of the signal sent by the base station. The larger the ratio, the greater the degree of interference; the smaller the ratio, the smaller the degree of interference. For example, assuming that the beam interference degree in the target area is 0.9, the preset interference threshold C1 is 0.8, and the beam interference degree is greater than C1, step S1223 is performed.

In other embodiments of the present disclosure, the degree of beam interference is represented by SINR, and step S1221 should be adjusted to: determine whether the SINR of the target area is less than or equal to a preset interference threshold. If it is determined that the SINR of the target area is less than or equal to the preset interference threshold, step S1223 is performed; otherwise, step S1222 is performed. For example, it is assumed that the SINR in the target area is 3dB, the preset interference threshold is 5dB, and the SINR is less than the preset interference threshold, indicating that the interference is relatively large, and step S1223 is performed.

Step S1222: Determine whether the required signal coverage depth is greater than or equal to D1.

Wherein, D1 is a preset depth threshold. In step S1222, the required signal coverage depth in the target area corresponding to the base station is compared with a preset depth threshold. When the required signal coverage depth is greater than or equal to D1, step S1223 is performed; when the required signal coverage depth is less than D1, step S1224 is performed.

In some embodiments, the required signal coverage depth is a ratio of the signal coverage distance required by the user in the target area to the preset base station signal coverage distance. The larger the ratio, the greater the required signal coverage depth; the smaller the ratio, the smaller the required signal coverage depth. For example, assuming that the required signal coverage depth in the target area is 0.8, the preset depth threshold D1 is 0.7, and the required signal coverage depth is greater than D1, step S1223 is performed.

In other embodiments of the present disclosure, step S1222 may also be performed first, and then step S1221 may be performed. That is, it is firstly judged whether the required signal coverage depth is greater than or equal to D1, and if the judgment result is no, it is then judged whether the degree of beam interference is greater than or equal to C1.

Step S1223: Determine the target beamforming mode of the base station as the first beamforming mode.

The first beamforming mode is a single beamforming mode, and the beamwidth is narrower than that of other modes. By adopting the first beamforming mode, the anti-interference capability of the uplink and downlink signals of the base station can be improved, and the coverage and capacity of the base station signals can be improved.

Step S1224: Determine whether the user dispersion degree is greater than or equal to E1.

Wherein, E1 is a preset dispersion degree threshold. In step S1224, the user dispersion degree in the preset direction is compared with the preset dispersion degree threshold E1. If the user dispersion degree in at least one preset direction is greater than or equal to E1, step S1226 is performed; if the user dispersion degree in all preset directions is less than E1, step S1225 is performed.

In some embodiments, the preset orientation includes a landscape orientation and a portrait orientation. If the user dispersion degree in the horizontal direction is greater than or equal to the first dispersion degree threshold, or, in the case that the user dispersion degree in the vertical direction is greater than or equal to the second dispersion degree threshold, step S1226 is performed; the user dispersion degree in the horizontal direction If it is smaller than the first dispersion degree threshold and the user dispersion degree in the vertical direction is smaller than the second dispersion degree threshold, step S1225 is executed. Wherein, the first dispersion degree threshold and the second dispersion degree threshold may be the same or different.

In some embodiments, the target area is divided into a plurality of sub-areas in a preset direction, and the ratio of the number of sub-areas with user distribution in the target area to the total number of sub-areas is used as the user dispersion in the preset direction degree. The larger the ratio, the greater the degree of dispersion; the smaller the ratio, the smaller the degree of dispersion. For example, the target area is vertically divided into three sub-regions: upper, middle, and lower. If all three sub-regions have user distribution, the user dispersion degree is 1. If only two sub-regions have user distribution, the user dispersion degree for

Step S1225: Determine whether the proportion of users with preset data package service requirements is greater than or equal to F1.

Among them, F1 is a preset ratio threshold. In step S1225, the proportion of users who have preset data packet service requirements in the target area corresponding to the base station is compared with a preset proportion threshold F1. When the proportion of users with preset data package service requirements is greater than or equal to F1, step S1226 is performed; when the proportion of users with preset data package service requirements is less than F1, step S1227 is performed.

In other embodiments of the present disclosure, step S1225 may also be performed first, and then step S1224 may be performed. That is, it is first judged whether the proportion of users with preset data package service requirements is greater than or equal to F1, and if the judgment result is no, it is then judged whether the degree of user dispersion in the preset direction is greater than or equal to E1.

Step S1226: Determine that the target beamforming mode of the base station is the second beamforming mode.

The second beamforming mode is a multi-beamforming mode, and the beam width of the second beamforming mode is wider than that of the first beamforming mode.

Step S1227: Determine whether the user distribution is aggregated in the first area or the second area in the preset direction.

In some embodiments, the preset direction is a longitudinal direction, and the first area and the second area are two areas divided in the longitudinal direction. For example, the first region is a longitudinal middle and lower part region, and the second region is a longitudinal middle and upper part region.

In the case that the users are distributed to gather in the first area in the preset direction, step S1228 is performed; in the case that the users are distributed to be aggregated in the second area of the preset direction, step S1229 is performed.

Step S1228: Determine the target beamforming mode of the base station as the third beamforming mode.

The third beamforming mode is a single beamforming mode in which the coverage area corresponds to the first area, and the coverage area is smaller than the first beamforming mode and the second beamforming mode.

Step S1229: Determine the target beamforming mode of the base station as the fourth beamforming mode.

The fourth beamforming mode is a single beamforming mode in which the coverage area corresponds to the second area, and the coverage area is smaller than that of the first beamforming mode and the second beamforming mode.

In the embodiment of the present disclosure, through the above steps, the optimal beamforming mode can be adaptively determined according to the monitoring index data of the target area corresponding to the base station, thereby effectively improving the beamforming capability of the base station and satisfying the coverage capability of the base station in different service scenarios. and capacity requirements to improve mobile communication network performance and user experience.

When the value of Analog_Multibeam is True, it means that multi-beam is used, and when the value of Analog_Multibeam is False, it means that narrow beam is used; the first beam coverage parameter It is the vertical full coverage parameter, which is represented as Vertical_Full_Coverage, and its value range is {True, False}. When the value of Vertical_Full_Coverage is True, it means that the beam coverage is vertical full coverage. When the value of Vertical_Full_Coverage is False, it means that the beam is covered. The coverage is the vertical partial coverage; the second beam coverage is the vertical partial coverage parameter, which is represented as Vertical_Partial_Coverage, and its value range is {Top_to_Middle, Middle_to_Bottom}. When the Vertical_Partial_Coverage value is Top_to_Middle, it indicates that the beam coverage is vertical middle and upper part, when the value of Vertical_Partial_Coverage is Middle_to_Bottom, it indicates that the beam coverage is the middle and lower part of the vertical.
