[0042] Figure 1 FIG. 4 is a flow chart showing a beamforming control method according to some embodiments of the present disclosure. Figure 1 As shown, the beamforming control method of the embodiment of the present disclosure includes:

[0043] Step S110: Acquire monitoring index data of the target area corresponding to the base station.

[0044] In some embodiments, the monitoring index data of the target area corresponding to the base station includes: at least one of user location information, interference signal measurement information, and user service demand in the target area corresponding to the base station.

[0045] In some embodiments, step S110 includes: receiving measurement report information sent by multiple user terminals within the target area corresponding to the base station, and obtaining user location information from the measurement report information; receiving interference signal measurement information sent by multiple user terminals within the target area corresponding to the base station; and determining the user's service needs based on at least one of the uplink and downlink traffic of the multiple user terminals within the target area corresponding to the base station.

[0046] In some embodiments, the interference signal measurement information includes at least one of uplink reference signal measurement information and downlink reference signal measurement information. Exemplarily, the uplink reference signal includes an uplink interference signal and a signal sent by a base station of a cell where the user terminal is located, and the uplink reference signal measurement information includes: the strength of the uplink interference signal and the strength of the signal sent by the base station of the cell where the user terminal is located.

[0047] Step S120: Determine a target beamforming mode of the base station according to monitoring indicator data of the target area corresponding to the base station.

[0048] In some embodiments, the target beamforming mode is determined based on at least one of user location information within a target area corresponding to the base station, interference signal measurement information, and user service requirements.

[0049] Step S130: Generate and output a control signal according to the target beamforming mode of the base station.

[0050] In some embodiments, step S130 includes: generating and outputting a control signal when the target beamforming mode of the base station is different from the beamforming mode currently used by the base station; and terminating the current beamforming control process when the target beamforming mode of the base station is the same as the beamforming mode currently used by the base station. The control signal is used to switch the currently used signal processing circuit to the signal processing circuit corresponding to the target beamforming mode.

[0051] For example, assuming that the target beamforming mode is the first beamforming mode and the beamforming mode currently used by the base station is the second beamforming mode, a control signal is generated and sent to the switching component to control the switching component to switch the currently used signal processing circuit to the signal processing circuit corresponding to the target beamforming mode; assuming that the target beamforming mode is the first beamforming mode and the beamforming mode currently used by the base station is the first beamforming mode, the beamforming control process is ended.

[0052] In the disclosed embodiment, the above steps can realize the adaptive switching of the beamforming mode of the base station, effectively improve the beamforming capability of the base station, meet the requirements of different business scenarios for base station coverage and capacity, improve the utilization rate of access network resources, and improve spectrum efficiency and user experience. It has strong pertinence and very important deployment significance and practical value for the evolution of wireless networks towards 5G+.

[0053] Figure 2a FIG. 4 is a flowchart illustrating determining a beamforming mode according to some embodiments of the present disclosure. Figure 2a As shown, the process of determining the beamforming mode in the embodiment of the present disclosure includes:

[0054] Step S121: Determine intermediate indicator data according to the monitoring indicator data of the target area corresponding to the base station.

[0055] In some embodiments, the intermediate indicator data includes at least one of the degree of beam interference in the target area, the required signal coverage depth, user distribution, and the proportion of users with preset data packet service requirements.

[0056] Among them, 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 to the signal strength of the base station is used as the beam interference degree of the target area. In other embodiments, the signal to interference plus noise ratio (SINR) is used as a characterization indicator of the beam interference degree of the target area. The larger the SINR, the smaller the signal interference degree; the smaller the SINR, the greater the signal interference degree.

[0057] Among them, 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 depth is determined according to the coverage distance of the signal required by the user and the coverage distance of the preset base station signal. For example, the ratio of the coverage distance of the signal required by the user and the coverage distance of the preset base station signal is taken 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 overall distribution of users is within 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 coverage distance of the preset base station signal is 500 meters. The required signal coverage depth is calculated to be 0.8.

[0058] The proportion of users with preset data package service requirements is determined based on the service requirements of users in the target area.

[0059] In some embodiments, the number of users with preset data packet service demands 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 demands in the target area and the total number of users in the target area are used as the proportion of users with preset data packet service demands. Exemplarily, the preset data packet may be a data packet with a data volume greater than a preset data volume threshold.

[0060] Step S122: Determine the target beamforming mode of the base station according to the intermediate indicator data.

[0061] Exemplarily, the target beamforming mode of the base station is determined based on at least one of the beam interference level of the target area, the required signal coverage depth, the user distribution, and the proportion of users with preset data packet service requirements.

[0062] In some embodiments, the intermediate indicator data includes the degree of beam interference of the target area and the required signal coverage depth. Step S122 includes: when the degree of beam interference of the target area is greater than or equal to a preset interference threshold, or the required signal coverage depth is greater than a preset depth threshold, determining that the target beamforming mode of the base station is the first beamforming mode; when the degree of beam interference of the target area is less than the preset interference threshold, and the required signal coverage depth is less than the preset depth threshold, determining 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 narrower than the beam width of other modes.

[0063] In other embodiments, the intermediate indicator data include the beam interference level of the target area, the required signal coverage depth, the user distribution, and the proportion of users with preset data packet service requirements, and step S122 includes steps A1 to A5.

[0064] Step A1: determine whether the beam interference degree of the target area is greater than or equal to a preset interference threshold, or whether the required signal coverage depth is greater than a preset depth threshold.

[0065] If the judgment result of step A1 is yes, execute step A2; if the judgment result of step A1 is no, execute step A3.

[0066] In other embodiments of the present disclosure, when the beam interference degree 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, execute step A2; otherwise, execute step A3.

[0067] Step A2: Determine that the target beamforming mode of the base station is a first beamforming mode, wherein the first beamforming mode is a single beamforming mode, and the beam width is narrower than the beam widths of other modes.

[0068] 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.

[0069] If the judgment result of step A3 is yes, execute step A4; if the judgment result of step A3 is no, execute step A5.

[0070] Step A4: Determine that the target beamforming mode is a second beamforming mode, wherein the second beamforming mode is a multi-beamforming mode.

[0071] Step A5: Determine the target beamforming mode as a mode other than the first and second beamforming modes.

[0072] In the disclosed embodiment, the above steps can adaptively determine the target beamforming mode of the base station according to the monitoring index data, thereby effectively improving the beamforming capability of the base station, meeting the requirements of different business scenarios for beamforming modes, and improving the performance of the mobile communication network and user experience.

[0073] Figure 2b FIG. 1 is a flowchart showing a method for determining a beamforming mode according to some other embodiments of the present disclosure. Figure 2b In the embodiment, the detailed process of step S122 is exemplarily described. Figure 2b As shown, the process of determining the beamforming mode in the embodiment of the present disclosure includes:

[0074] Step S1221: Determine whether the beam interference degree is greater than or equal to C1.

[0075] 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 the preset interference threshold. If the beam interference degree is greater than or equal to C1, step S1223 is executed; if the beam interference degree is less than C1, step S1222 is executed.

[0076] 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 interference degree; the smaller the ratio, the smaller the interference degree. 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 executed.

[0077] In other embodiments of the present disclosure, the beam interference degree is characterized by SINR, and step S1221 should be adjusted to: determine whether the SINR of the target area is less than or equal to the preset interference threshold. If the SINR of the target area is less than or equal to the preset interference threshold, execute step S1223; otherwise, execute step S1222. For example, assuming 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, it indicates that the interference is relatively large, and step S1223 is executed.

[0078] Step S1222: Determine whether the required signal coverage depth is greater than or equal to D1.

[0079] 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 the preset depth threshold. If the required signal coverage depth is greater than or equal to D1, step S1223 is executed; if the required signal coverage depth is less than D1, step S1224 is executed.

[0080] In some embodiments, the required signal coverage depth is the 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 executed.

[0081] In other embodiments of the present disclosure, step S1222 may be performed first, and then step S1221 may be performed. That is, first determine whether the required signal coverage depth is greater than or equal to D1, and if the determination result is no, then determine whether the beam interference degree is greater than or equal to C1.

[0082] Step S1223: Determine that the target beamforming mode of the base station is the first beamforming mode.

[0083] The first beamforming mode is a single beamforming mode, and the beam width is narrower than the beam width 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 signal can be improved.

[0084] Step S1224: Determine whether the user dispersion degree is greater than or equal to E1.

[0085] 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 executed; if the user dispersion degree in all preset directions is less than E1, step S1225 is executed.

[0086] In some embodiments, the preset direction includes a horizontal direction and a vertical direction. When the user dispersion degree in the horizontal direction is greater than or equal to a first dispersion degree threshold, or when the user dispersion degree in the vertical direction is greater than or equal to a second dispersion degree threshold, step S1226 is performed; when the user dispersion degree in the horizontal direction is less than the first dispersion degree threshold, and the user dispersion degree in the vertical direction is less than the second dispersion degree threshold, step S1225 is performed. The first dispersion degree threshold and the second dispersion degree threshold may be the same or different.

[0087] In some embodiments, the target area is divided into multiple sub-areas in a preset direction, and the ratio of the number of sub-areas with users in the target area to the total number of sub-areas is used as the user dispersion degree in the preset direction. The larger the ratio, the greater the dispersion degree; the smaller the ratio, the smaller the dispersion degree. For example, the target area is divided into three sub-areas, upper, middle, and lower, in the vertical direction. If all three sub-areas have users, the user dispersion degree is 1; if only two sub-areas have users, the user dispersion degree is 2.

[0088] Step S1225: Determine whether the proportion of users with preset data packet service requirements is greater than or equal to F1.

[0089] Wherein, F1 is a preset ratio threshold. In step S1225, the proportion of users with preset data packet service demand in the target area corresponding to the base station is compared with the preset ratio threshold F1. If the proportion of users with preset data packet service demand is greater than or equal to F1, step S1226 is executed; if the proportion of users with preset data packet service demand is less than F1, step S1227 is executed.

[0090] In other embodiments of the present disclosure, step S1225 may be performed first, and then step S1224 may be performed. That is, first determine whether the proportion of users with preset data packet service requirements is greater than or equal to F1, and if the determination result is no, then determine whether the user dispersion degree in the preset direction is greater than or equal to E1.

[0091] Step S1226: Determine that the target beamforming mode of the base station is the second beamforming mode.

[0092] 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.

[0093] Step S1227: Determine whether the user distribution is concentrated in the first area or the second area in the preset direction.

[0094] In some embodiments, the preset direction is the longitudinal direction, and the first area and the second area are two areas divided in the longitudinal direction. For example, the first area is the middle and lower area in the longitudinal direction, and the second area is the middle and upper area in the longitudinal direction.

[0095] When the user distribution is concentrated in a first area in a preset direction, step S1228 is executed; when the user distribution is concentrated in a second area in a preset direction, step S1229 is executed.

[0096] Step S1228: Determine that the target beamforming mode of the base station is the third beamforming mode.

[0097] The third beamforming mode is a single beamforming mode whose coverage area corresponds to the first area, and whose coverage range is smaller than those of the first beamforming mode and the second beamforming mode.

[0098] Step S1229: Determine that the target beamforming mode of the base station is the fourth beamforming mode.

[0099] The fourth beamforming mode is a single beamforming mode whose coverage area corresponds to the second area, and the coverage range is smaller than the first beamforming mode and the second beamforming mode.

[0100] In the disclosed embodiment, the above steps can adaptively determine the optimal beamforming mode according to the monitoring index data of the target area corresponding to the base station, effectively improve the beamforming capability of the base station, meet the requirements of different business scenarios for base station coverage capability and capacity, and improve the performance of the mobile communication network and user experience.

[0102] Step S310: base station startup and parameter initialization.

[0103] In some embodiments, step S310 includes: starting the base station, and then initializing beam parameters, wherein the beam parameters include: beam width parameter, beam number parameter, first beam coverage range parameter, and second beam coverage range parameter.

[0104] For example, the beam width parameter is expressed as Beam_Width, and its value range is {Wide, Narrow}. When the value of Beam_Width is Wide, it means that a wide beam is used. When the value of Beam_Width is Narrow, it means that a narrow beam is used. The number of beams parameter is expressed as Analog_Multibeam, and its value range is {True, False}. When the value of Analog_Multibeam is True, it means that a multi-beam is used. When the value of Analog_Multibeam is False, it means that a narrow beam is used. The first beam coverage parameter is the vertical full coverage parameter, expressed as Vertical_Full_Coverage, and its value range is {True, False}. When the value of Vertical_Full When the value of l_Coverage is True, it means that the beam coverage is full coverage in the vertical direction. When the value of Vertical_Full_Coverage is False, it means that the beam coverage is partial coverage in the vertical direction. The second beam coverage is the vertical partial coverage parameter, expressed as Vertical_Partial_Coverage, and its value range is {Top_to_Middle, Middle_to_Bottom}. When the value of Vertical_Partial_Coverage is Top_to_Middle, it means that the beam coverage is the middle and upper part in the vertical direction. When the value of Vertical_Partial_Coverage is Middle_to_Bottom, it means that the beam coverage is the middle and lower part in the vertical direction.

[0105] Step S320: Acquire monitoring index data of the target area of ​​the base station.
