There are more and more indoor micro stations (5G smart homes, smart factories, virtual reality (VR) and augmented reality (AR), etc.). When macro stations and micro stations are networked on the same frequency, macro stations will cause co-frequency interference to micro stations.

[0003] For example, in the high-speed rail scenario, when the public network and the private network have the same frequency point or frequency band overlap, the public network will interfere with the private network. When the interference between the public and private networks is large, it will seriously affect the network performance of the high-speed rail and the public network. Therefore, how to adjust the antenna weight parameters to reduce the co-frequency interference between cells is an urgent problem to be solved. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

[0022] It should be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present specification, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0023] The embodiment of the present invention provides a method for adjusting the antenna weight parameters of a base station, a base station and a storage medium. The antenna weight parameter adjustment method can be applied to a base station, which can be a base station of a macro base station, a micro base station, a pico base station, a femto base station and other types of base stations. For example, when the base station is a macro base station, the macro base station obtains at least two measurement report information and cell working parameter information in a target area, and the target area at least includes an overlapping area between an area to be optimized and a non-optimized area; according to each measurement report information and the cell working parameter information, the target measurement report information is determined, and the target measurement report information is the measurement report information corresponding to the user equipment in the overlapping area; according to each measurement report information and the target measurement report information, the target antenna weight parameter that meets the preset restriction condition is determined, so that the antenna weight of the cell in the area to be optimized is adjusted.

[0024] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0025] Please refer to Figure 1 , Figure 1 A schematic diagram of a flow chart of a method for adjusting antenna weight parameters provided by an embodiment of the present invention.

[0026] like Figure 1 As shown, the antenna weight parameter adjustment method includes steps S101 to S103.

[0027] Step S101: Acquire at least two pieces of measurement report information and cell engineering parameter information in a target area, where the target area at least includes an overlapping area between an area to be optimized and a non-optimized area.

[0028] Among them, the area to be optimized is the area in the target area where the antenna weight parameters need to be adjusted, and the non-optimized area is the area in the target area where the antenna weight parameters are not adjusted. In one embodiment, in the scenario of indoor and outdoor co-frequency networking, the area to be optimized may be the area covered by the outdoor macro base station, and the non-optimized area may be the area covered by the indoor micro base station; in the scenario of high-speed rail public network and private network coverage, the area to be optimized may be the area covered by the public network, and the non-optimized area may be the area covered by the private network.

[0029] For example, Figure 2 As shown, the target area includes an area to be optimized 10 and a non-optimized area 20, wherein there is an overlapping area 30 between the area to be optimized 10 and the non-optimized area 20. When the terminal device is in the overlapping area 30 and accesses the cell of the base station to which the non-optimized area 20 belongs, the communication signal broadcast by the cell to which the area to be optimized 10 belongs will affect the communication service of the terminal device.

[0030] It should be noted that the measurement report (MR) information includes the service cell identity document (ID), neighboring cell ID, reference signal receiving power (RSRP), direction of arrival (DOA), uplink path loss, time advanced (TA) and signal to interference plus noise ratio (SINR). The cell engineering parameter information includes cell ID, active antenna unit (AAU) attributes, longitude and latitude information and center frequency.

[0031] In one embodiment, measurement report information reported by each user device in the target area is obtained to obtain multiple measurement report information in the target area. The user device can be set according to actual conditions, and the embodiment of the present invention does not specifically limit this. For example, the user device can be a mobile phone, a tablet computer, a desktop computer, a router, etc. By obtaining the measurement report information reported by each user device in the target area, the efficiency and accuracy of antenna weight parameter adjustment can be improved.

[0032] In one embodiment, the engineering parameter information of each cell in the target area is obtained to obtain the engineering parameter information of the cells in the target area. By obtaining the engineering parameter information of the cells in the target area, the efficiency and accuracy of antenna weight parameter adjustment can be improved.

[0033] Step S102: Determine target measurement report information according to each of the measurement report information and the cell engineering parameter information, where the target measurement report information is measurement report information corresponding to the user equipment in the overlapping area.

[0034] Wherein, when the user equipment reporting the measurement report information is in the overlapping area, the measurement report information is determined as the target measurement report information. Figure 3 As shown, the target area includes measurement report information A, measurement report information B, measurement report information C, measurement report information D, measurement report information E, measurement report information F, measurement report information G and measurement report information H, wherein the user equipment corresponding to the measurement report information A, measurement report information B, measurement report information C, measurement report information D, measurement report information E and measurement report information F is in a non-overlapping area, and the user equipment corresponding to the measurement report information G and the measurement report information H is in an overlapping area 30, then the measurement report information G and the measurement report information H are determined as the target measurement report information.

[0035] In one embodiment, if Figure 4 As shown, step S102 includes sub-steps S1021 and S1022.

[0036] Sub-step S1021: Determine the area to which the user equipment corresponding to each measurement report information belongs according to each measurement report information and the cell engineering parameter information.

[0037] The area to which the user equipment belongs includes an area to be optimized and a non-optimized area.

[0038] In one embodiment, the target area to which each cell belongs is determined according to at least one of the cell identification number ID, active antenna unit attribute, longitude and latitude, and center frequency in the cell engineering parameter information; and the target area to which each cell belongs is determined as the area to which the user equipment belongs according to the service cell ID in each measurement report information and the target area to which each cell belongs. The area to which the user equipment corresponding to each measurement report information belongs can be accurately determined according to the cell engineering parameter information and the measurement report information, which greatly improves the efficiency and accuracy of adjusting the antenna weight parameters.

[0039] In one embodiment, according to the cell identity ID in the cell engineering parameter information, the method of determining the target area to which each cell belongs can be: obtaining a mapping relationship table between a preset cell ID and a location area, querying the location area corresponding to each cell ID from the mapping relationship table, and obtaining the target area to which each cell belongs. Among them, the mapping relationship table is established in advance according to the cell ID and the location area, and the mapping relationship table can be established according to the actual situation, which is not specifically limited in the embodiment of the present invention. The target area to which each cell belongs can be accurately queried through the mapping relationship table and the cell ID.

[0040] In one embodiment, the method for determining the target area to which each cell belongs based on at least one of the active antenna unit attributes, longitude and latitude, and center frequency in the cell engineering parameter information can be: querying the geographical area where each cell is located based on at least one of the active antenna unit attributes, longitude and latitude, and center frequency to obtain the target area to which each cell belongs.

[0041] In one embodiment, based on the service cell ID in each measurement report information and the target area to which each cell belongs, a method for determining the target area to which the service cell where each user equipment is located as the area to which the user equipment belongs can be: querying the area corresponding to the service cell ID in each measurement report information from the target area to which each cell belongs, obtaining the target area to which the service cell where each user equipment is located belongs, and using the target area as the area to which the user equipment belongs.

[0042] In one embodiment, the user equipment including valid wave direction information, sounding reference signal transmission power, and sounding reference signal reception power in the measurement report information is determined as the user equipment in the area to be optimized; the user equipment corresponding to the measurement report information in which at least one of the wave direction information, sounding reference signal transmission power, and sounding reference signal reception power is abnormal is determined as the user equipment in the non-area to be optimized. By determining whether the measurement report information contains valid wave direction information, sounding reference signal transmission power, and sounding reference signal reception power, the area to which the user equipment corresponding to each measurement report information belongs can be accurately determined, which greatly improves the efficiency and accuracy of adjusting the antenna weight parameters.

[0043] Exemplarily, the measurement report information includes measurement report information 1, measurement report information 2, measurement report information 3, measurement report information 4 and measurement report information 5, wherein measurement report information 1, measurement report information 2 and measurement report information 5 include valid wave direction information, detection reference signal transmission power, and detection reference signal reception power, and the area to which the user equipment corresponding to measurement report information 1, measurement report information 2 and measurement report information 5 belongs is a to-be-optimized area; measurement report information 3 and measurement report information 4 include invalid wave direction information, detection reference signal transmission power, and detection reference signal reception power, and the area to which the user equipment corresponding to measurement report information 3 and measurement report information 4 belongs is a non-optimized area.

[0044] Sub-step S1022: determining target measurement report information from each measurement report information according to the area to which each user equipment belongs.

[0045] The measurement report information includes a reference signal received power (RSRP), and the RSRP includes a first RSRP and a second RSRP. It should be noted that the first RSRP is the RSRP of the area to be optimized in the measurement report information, and the second RSRP is the RSRP of the non-optimized area in the measurement report information.

[0046] In one embodiment, it is determined whether there is a user device whose first RSRP belonging to the area to be optimized is greater than a preset first threshold, whose second RSRP belonging to the non-optimized area is greater than a preset second threshold, and whose difference between the second RSRP and the first RSRP is less than a preset third threshold; in the case where there is a user device whose first RSRP belonging to the area to be optimized is greater than the preset first threshold, whose second RSRP belonging to the non-optimized area is greater than the preset second threshold, and whose difference between the second RSRP and the first RSRP is less than the preset third threshold, it is determined to be a user device in the overlapping area; and the measurement report information corresponding to the user device in the overlapping area is determined as the target measurement report information. Among them, the preset first threshold, the preset second threshold and the preset third threshold can be set according to the actual situation, and the embodiment of the present invention does not make specific limitations on this. According to the RSRP in the measurement report information, it can be accurately determined whether each measurement report information is the target measurement report information in the overlapping area.

[0047] Step S103: Determine a target antenna weight parameter that meets a preset restriction condition according to each of the measurement report information and the target measurement report information, so as to adjust the antenna weight of the cell in the area to be optimized.

[0048] The preset restriction condition is that the measurement report information in the overlapping area accounts for a small proportion and the coverage quality index is high.

[0049] In one embodiment, if Figure 5 As shown, step S103 includes sub-steps S1031 and S1032.

[0050] Sub-step S1031: determine the ratio of the number of reports of the target measurement report information to the number of reports of the measurement report information, and obtain the proportion of the target measurement report information in the overlapping area.

[0051] The number of target measurement report information is counted to obtain the number of target measurement report information reports; the number of each measurement report information is counted to obtain the number of measurement report information reports; and the number of target measurement report information reports is divided by the number of measurement report information reports to obtain the target measurement report information ratio in the overlapping area. By calculating the target measurement report information ratio in the overlapping area, the accuracy of antenna weight adjustment can be improved.

[0052] Exemplarily, the number of reports of target measurement report information is 50, and the number of reports of measurement report information is 2000, then the proportion of target measurement report information in the overlapping area is 0.025.

[0053] Sub-step S1032: determining a target antenna weight parameter that meets a preset restriction condition according to the target measurement report information ratio and each of the measurement report information.

[0054] In one embodiment, the coverage quality index of the user equipment in the non-overlapping area is determined according to each measurement report information, and the coverage quality index is used to characterize the communication quality index of the user equipment in the non-overlapping area; the antenna weight parameters of the cell corresponding to the area to be optimized are adjusted multiple times to obtain multiple candidate antenna weight parameters, and multiple candidate RSRPs and candidate signal to interference plus noise ratios SINRs are determined according to each candidate antenna weight parameter and each measurement report information; according to the target measurement report information ratio, the coverage quality index, each candidate RSRP and each candidate SINR, the target antenna weight parameters that meet the preset restriction conditions are determined. By determining the target measurement report information ratio, the coverage quality index, each candidate RSRP and each candidate SINR, and according to the target measurement report information ratio, the coverage quality index, each candidate RSRP and each candidate SINR, the target antenna weight parameters that meet the preset restriction conditions can be accurately determined.

[0055] It should be noted that the coverage quality index includes at least one of the average RSRP in the non-overlapping area, the average SINR in the non-overlapping area, the Channel Quality Indicator (CQI) quality ratio, the split ratio of 5G traffic to 4G traffic, and the number of wireless resource control connected users. The antenna weight parameters include azimuth, downtilt angle, horizontal beamwidth, vertical beamwidth and power factor. Adjusting the antenna weight parameters can adjust at least one of the azimuth, downtilt angle, horizontal beamwidth, vertical beamwidth and power factor. For example, adjusting the antenna weight parameters is to adjust the downtilt angle and horizontal beamwidth.

[0056] In one embodiment, according to each measurement report information, the coverage quality index of the user equipment in the non-overlapping area can be determined in the following manner: when the coverage quality index only includes the average RSRP of the non-overlapping area, the sum of the RSRP in each measurement report information in the area to be optimized and not in the overlapping area is divided by the number of reports of the measurement report information in the area to be optimized and not in the overlapping area to obtain the average RSRP of the non-overlapping area. By calculating the average RSRP of the non-overlapping area, the coverage quality index can be accurately obtained.

[0057] In one embodiment, according to each measurement report information, the coverage quality index of the user equipment in the non-overlapping area can be determined in the following manner: when the coverage quality index only includes the average SINR of the non-overlapping area, the sum of the SINRs in each measurement report information in the area to be optimized and not in the overlapping area is divided by the number of reports of the measurement report information in the area to be optimized and not in the overlapping area to obtain the average SINR of the non-overlapping area. By calculating the average SINR of the non-overlapping area, the coverage quality index can be accurately obtained.

[0058] In one embodiment, according to each measurement report information, the coverage quality index of the user equipment in the non-overlapping area can be determined by: when the coverage quality index includes the average RSRP of the non-overlapping area and the average SINR of the non-overlapping area, obtaining the first weight parameter corresponding to the average RSRP of the non-overlapping area and the second weight parameter corresponding to the average SINR of the non-overlapping area, and generating the coverage quality index according to the first weight parameter, the second weight parameter, the average RSRP of the non-overlapping area and the average SINR of the non-overlapping area. By weighting the average RSRP of the non-overlapping area and the average SINR of the non-overlapping area to generate the coverage quality index, the accuracy of the coverage quality index can be improved.

[0059] In one embodiment, the method for obtaining the first weight parameter corresponding to the average RSRP of the non-overlapping area and the second weight parameter corresponding to the average SINR of the non-overlapping area can be: based on the preset algorithm, the average RSRP of the non-overlapping area and the average SINR of the non-overlapping area are processed to obtain the first weight parameter and the second weight parameter. Among them, the preset algorithm can be selected according to actual conditions, and the embodiment of the present invention does not make specific limitations on this. By processing the average RSRP of the non-overlapping area and the average SINR of the non-overlapping area through the preset algorithm, the first weight parameter and the second weight parameter can be accurately obtained, which greatly improves the efficiency and accuracy of the antenna weight parameter adjustment.

[0060] Exemplarily, the preset algorithm may be a weighted sum algorithm, which is subject to x∈Ω, where λ i is the weight parameter, f i (x) is the average RSRP of the non-overlapping area or the average SINR of the non-overlapping area. The average RSRP of the non-overlapping area and the average SINR of the non-overlapping area are processed based on the weight summation algorithm, and the weight parameters corresponding to the average RSRP of the non-overlapping area and the average SINR of the non-overlapping area at Pareto optimality are determined to obtain the first weight parameter and the second weight parameter.

[0061] It should be noted that the first weight parameter and the second weight parameter can also be set according to actual conditions, and the specific setting rules can be determined according to actual conditions. The embodiment of the present invention does not make specific limitations on this. By setting the first weight parameter and the second weight parameter by yourself, the efficiency of adjusting the antenna weight parameters can be improved.

[0062] In one embodiment, according to each candidate antenna weight parameter and each measurement report information, a method of determining multiple candidate RSRPs and multiple candidate SINRs may be: calculating each candidate antenna weight parameter and RSRP in the measurement report information based on a preset RSRP formula to obtain each candidate RSRP; calculating each candidate RSRP and a preset white noise power based on a preset SINR formula to obtain each candidate SINR. By calculating each candidate antenna weight parameter and each measurement report information, multiple candidate RSRPs and multiple candidate SINRs can be accurately obtained.

[0063] In one embodiment, each candidate antenna weight parameter and RSRP in the measurement report information are calculated based on a preset RSRP formula, and a method for obtaining each candidate RSRP may be: the preset RSRP formula is RSRPi,j=RSRPi,k+AntGainTbl[j][h][v]-AntGainTbl[k][h][v], wherein RSRPi,j is the RSRP when the j antenna weight parameter is used, RSRPi,k is the RSRP when the k antenna weight parameter is used, AntGainTbl[j] is the antenna gain value when the antenna weight parameter is j, [h][v] is the DOA angle of the user equipment, and AntGainTbl[k] is the antenna gain value when the antenna weight parameter is k. Based on the preset RSRP formula, each candidate antenna weight parameter and RSRP in the measurement report information are calculated to obtain each candidate RSRP.

[0064] It should be noted that AntGainTbl is queried in a preset antenna gain table, and the preset antenna gain table can be set according to actual conditions, and the embodiment of the present invention does not make any specific limitation to this.

[0065] In one embodiment, each candidate RSRP and a preset white noise power are calculated based on a preset SINR formula to obtain each candidate SINR: The preset SINR formula is: in, is the candidate RSRP of the user equipment, RSRP is the RSRP of the cell served by the user equipment, and the M RSRP is the sum of RSRPs of neighboring cells, and N is the white noise power; based on the preset SINR formula, the sum of RSRPs of RSRP neighboring cells of the served cell and the white noise power are calculated to obtain a candidate SINR.

[0066] It should be noted that converting the candidate RSRP into a linear value before performing the candidate SINR can improve the accuracy of the candidate SINR. The white noise power can be set according to the actual situation, and the embodiment of the present invention does not make specific restrictions on this. For example, the white noise power can be set to -125dBm, and the candidate SINR sets a maximum threshold and a minimum threshold. The maximum threshold and the minimum threshold can be set according to the actual situation, and the embodiment of the present invention does not make specific restrictions on this. For example, the maximum threshold can be 40dB, and the minimum threshold can be -20dB. By setting the maximum threshold and the minimum threshold, the candidate SINR with large errors can be removed to improve the accuracy of the antenna weight parameter adjustment.

[0067] In one embodiment, according to the target measurement report information ratio, the coverage quality index, each candidate RSRP and each candidate SINR, the method of determining the target antenna weight parameter that meets the preset restriction condition can be: determining the report ratio of the overlapping area measurement report information corresponding to each candidate antenna weight parameter according to each candidate RSRP, and obtaining the target measurement report information ratio of multiple overlapping areas; determining the coverage quality index of the user equipment in the non-overlapping area according to each candidate RSRP and each candidate SINR, and obtaining multiple coverage quality indicators; selecting the target antenna weight parameter from the candidate antenna weight parameters according to the multiple target measurement report information ratios and the multiple coverage quality indicators. Through the multiple target measurement report information ratios and the multiple coverage quality indicators, the target antenna weight parameter can be accurately selected from the multiple candidate antenna weight parameters.

[0068] In one embodiment, the reporting ratio of the overlapping area measurement report information corresponding to each candidate antenna weight parameter is determined according to each candidate RSRP, and the method for obtaining the target measurement report information ratio of multiple overlapping areas can be: determine that, under the condition of each candidate antenna weight parameter, in the case of a user device whose first candidate RSRP belonging to the area to be optimized is greater than a preset first threshold, whose second candidate RSRP belonging to the non-optimized area is greater than a preset second threshold, and whose difference between the first candidate RSRP and the second candidate RSRP is less than a preset third threshold, it is determined to be a user device in the overlapping area; summarize the measurement report information corresponding to the user equipment in the overlapping area to obtain at least one target measurement report information; and place the report number of the target measurement report information in the report number of the measurement report information to obtain the target measurement report information ratio of the overlapping area.

[0069] In one embodiment, the coverage quality index of the user equipment in the non-overlapping area is determined according to each candidate RSRP and each candidate SINR, and the method for obtaining multiple coverage quality indicators can be: when the coverage quality index only includes the average RSRP of the non-overlapping area, the sum of the candidate RSRPs in each measurement report information that is in the area to be optimized and not in the overlapping area is divided by the number of reports of the measurement report information that is in the area to be optimized and not in the overlapping area, to obtain the average RSRP of the non-overlapping area; when the coverage quality index only includes the average SINR of the non-overlapping area, the sum of the candidate SINRs in each measurement report information that is in the area to be optimized and not in the overlapping area is divided by the number of reports of the measurement report information that is in the area to be optimized and not in the overlapping area, to obtain the average SINR of the non-overlapping area; when the coverage quality index includes the average RSRP of the non-overlapping area and the average SINR of the non-overlapping area, a first weight parameter corresponding to the average RSRP of the non-overlapping area and a second weight parameter corresponding to the average SINR of the non-overlapping area are obtained, and the coverage quality index is generated according to the first weight parameter, the second weight parameter, the average RSRP of the non-overlapping area and the average SINR of the non-overlapping area.

[0070] In one embodiment, according to multiple target measurement report information ratios and multiple coverage quality indicators, the method of selecting the target antenna weight parameter from the candidate antenna weight parameters can be: selecting a preset number of target measurement report information ratios in order from small to large to obtain multiple candidate target measurement report information ratios; determining the candidate antenna weight parameter with the largest coverage quality indicator and the target measurement report information ratio located in the candidate target measurement report information ratio as the target antenna weight parameter. By selecting the optimal target antenna weight parameter from multiple candidate antenna weight parameters, the communication quality of user equipment in the overlapping area is improved.

[0071] In one embodiment, when the target antenna weight parameter is obtained, the antenna corresponding to each cell corresponding to the area to be optimized is adjusted according to the target antenna weight parameter to complete the adjustment of the antenna weight of the cell in the area to be optimized. The antenna weight of the cell in the area to be optimized is adjusted by the target antenna weight parameter, which greatly improves the communication quality of the user equipment in the overlapping area.

[0072] The base station antenna weight parameter adjustment method in the above embodiment obtains at least two measurement report information and cell working parameter information in the target area, and the target area at least includes the overlapping area between the area to be optimized and the non-optimized area; then, according to each measurement report information and the cell working parameter information, the target measurement report information is determined, and the target measurement report information is the measurement report information corresponding to the user equipment in the overlapping area; according to each measurement report information and the target measurement report information, the target antenna weight parameters that meet the preset restriction conditions can be accurately determined, so that the antenna weights of the cells in the area to be optimized can be adjusted. This scheme can accurately determine the target antenna weight parameters of the cells in the area to be optimized, and adjust the antenna weights of the cells in the area to be optimized by the target antenna weight parameters, which can optimize the co-channel interference between the cells in the target area, and greatly improve the communication quality and network performance in the target area.
