[0002] In 5G systems, for signal coverage optimization within a target area, the configuration of cell antenna parameters is usually completed based on expert experience or other optimization algorithms. For example, some heuristic intelligent optimization algorithms are used to obtain the combined solution of all cell azimuth angles, downtilt angles and other parameters within a specific coverage scenario area to complete the optimized configuration of cell antenna parameters. Once the cell antenna parameters are configured, the configuration values ​​will not be changed unless there are significant changes in the coverage scenario.

[0034] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0035] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0036] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0037] Figure 1 This is a schematic diagram illustrating a process for updating antenna parameters according to an embodiment of this disclosure, as shown below. Figure 1 As shown, the method includes the following steps:

[0038] S101, obtain the initial antenna feeder parameter vector of the target cell in the i-th iteration round, and the search direction set i corresponding to the i-th iteration round, where i is a positive integer.

[0039] The execution subject of the antenna feeder parameter update method provided in this disclosure is a network device. The network device can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system, etc. This disclosure does not limit the specific technology or device form used in the network device. The network device provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0040] The search direction set i may include multiple search directions.

[0041] It should be noted that if there are n antenna feeder parameters that need to be updated or optimized, then a set of search directions including n search directions needs to be constructed. Different search directions are used to update or optimize different antenna feeder parameters.

[0042] Assuming that there are n antenna parameters that need to be updated in the i-th iteration, then the search direction set i corresponding to the i-th iteration is {e1, e2, ..., e...} n}, where e1 = [1, 0, 0, ..., 0] T ,...,e n =[0,0,0,...,1] T T denotes transpose, n is a positive integer, e1, e2, ..., e n Indicates the search direction.

[0043] Antenna feeder parameters refer to the performance parameters of the antenna feeder system, including parameters such as Reference Signal Receiving Power (RSRP), antenna azimuth, antenna downtilt angle, angle of arrival, and antenna transmit power. An antenna feeder system refers to a system in which an antenna radiates electromagnetic waves into the surrounding space. An antenna feeder parameter vector refers to a vector containing multiple antenna feeder parameters. The target cell includes the antenna feeder system.

[0044] In this embodiment of the disclosure, during the iterative update of the antenna feeder parameter vector of the target cell across multiple iterations, the antenna feeder parameter vector of the current iteration (i.e., the i-th iteration) can be used as the initial antenna feeder parameter vector, and the search direction set i corresponding to the current iteration can be obtained. This set is used to perform iterative searches in each search direction set i, starting from the initial antenna feeder parameter vector, in the current iteration. Optionally, the initial antenna feeder parameter vector of the current iteration (i.e., the i-th iteration) can be the updated antenna feeder parameter vector obtained after completing the search in each search direction set i-1 in the (i-1)-th iteration.

[0045] In some implementations, the initial antenna feeder parameter vector for the i-th iteration of the target cell and the search direction set i corresponding to the i-th iteration can be obtained from the cell's engineering parameter table.

[0046] The initial antenna feed parameter vector can be expressed as: Where T represents transpose, the superscript indicates the iteration number, and the subscript indicates the value found by each component along the search direction set i in each iteration, for example... This represents the value obtained when the first component of the antenna feed parameter vector passes through the second search direction in sequence during the 0th search.

[0047] S102, starting from the initial antenna feed parameter vector, iteratively search in each search direction of the search direction set i to iteratively update the antenna feed parameter vector.

[0048] To obtain the initial antenna parameter vector of the target cell in the i-th iteration round. and the search direction set i{e1, e2, ..., e} corresponding to the i-th iteration roundn After that, the initial antenna feed parameter vector can be obtained. Initially, in the search direction set i{e1, e2, ..., e... n Perform an iterative search in each search direction.

[0049] First, the initial antenna feed parameter vector A one-dimensional search along the search direction e1 yields the antenna feed parameter vector.

[0050]

[0051] Where γ is the initial hyperparameter learning rate, which can generally be taken as 1.

[0052] Then, the antenna feed parameter vector A one-dimensional search along the search direction e2 can yield the antenna parameters.

[0053]

[0054] This iterative search continues until all search directions in the search direction set i have been searched, yielding the updated antenna parameter vector after the i-th iteration. This enables iterative updates to the antenna feed parameter vector.

[0055] S103, in response to the completion of the search in the search direction set i, update the search direction set i to obtain the search direction set i+1, so as to update the antenna parameter vector in the i+1th iteration.

[0056] Throughout the iterative search process, until the search direction set i{e1, e2, ..., e} is reached... n The last search direction (i.e., search direction e) n When the search is complete, the search direction set i{e1, e2, ..., e} is... n All search directions within the set i {e1, e2, ..., e} have been completed. n When all search directions within} have been completed, the search direction set i{e1, e2, ..., e...} can be processed. n The search direction in} is updated and adjusted to obtain a new search direction set i+1, which can be used to update the feed parameter vector in the (i+1)th iteration.

[0057] In some implementations, before updating the antenna parameter vector in the (i+1)th iteration, the last antenna parameter vector can be used as the initial antenna parameter vector for the (i+1)th iteration. This is used to update the antenna feed parameter vector in the (i+1)th iteration.

[0058] In this embodiment, the initial antenna feeder parameter vector of the target cell in the i-th iteration round and the search direction set i corresponding to the i-th iteration round are obtained. Starting from the initial antenna feeder parameter vector, iterative search is performed in each search direction of the search direction set i to iteratively update the antenna feeder parameter vector. In response to the completion of the search in the search direction set i, the search direction set i is updated to obtain the search direction set i+1, so as to update the antenna feeder parameter vector in the (i+1)-th iteration round. In this embodiment, the iterative update of the antenna feeder parameters realizes the real-time adaptive optimization and adjustment of the antenna feeder parameters, thereby enabling real-time tracking of the direction of the target user group with the optimal antenna feeder parameter configuration. This, in turn, strengthens the received signal strength of the terminal user by directional signal transmission, improving resource utilization and enhancing user experience.

[0059] Figure 2 This is a flowchart illustrating a method for updating antenna parameters according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 2 The process of updating the search direction set i to obtain the search direction set i+1 includes the following steps:

[0060] S201, obtain the initial antenna feeder parameter vector and the average RSRP value corresponding to each updated antenna feeder parameter vector.

[0061] RSRP is a key parameter in a network that represents the strength of a wireless signal and is one of the physical layer measurement requirements. It is the average signal power received on all REs (resource particles) carrying a reference signal within a certain symbol.

[0062] In some implementations, the initial antenna feed parameter vector is obtained. The RSRP value, and each updated antenna feed parameter vector (including The RSRP value of ) is used to calculate the... The corresponding average RSRP values

[0063] Each time an antenna feeder parameter vector is acquired, including the initial antenna feeder parameter vector, the antennas of the target cell can be configured based on this vector. After configuration, terminal devices within the target cell can report a measurement report, which may include RSRP. Network devices can then calculate the corresponding average RSRP value based on the RSRP reported by the terminal devices within the target cell.

[0064] S202, based on the updated antenna feed parameter vector and the average RSRP value, update the search direction set i to obtain the search direction set i+1.

[0065] In some implementations, a new search direction can be determined based on the updated antenna feed parameter vector, and the search direction that needs to be updated in the search direction set i can be determined based on the average RSRP value. The search direction that needs to be updated is then updated to the new search direction to obtain the search direction set i+1.

[0066] In this embodiment, an initial antenna feed parameter vector and the average RSRP value corresponding to each updated antenna feed parameter vector are obtained. Based on the updated antenna feed parameter vector and the average RSRP value, the search direction set i is updated to obtain the search direction set i+1. This embodiment implements the updating of the search direction set, thereby enabling the antenna feed parameter vector to be adaptively updated when searching on the updated search direction set.

[0067] Figure 3 This is a flowchart illustrating a method for updating antenna parameters according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 3 The process of updating the search direction set i to obtain the search direction set i+1 based on the updated antenna feed parameter vector and the average RSRP value is explained, including the following steps:

[0068] S301, obtain the difference vector between the initial antenna feed parameter vector and the last antenna feed parameter vector, and use it as the new replacement search direction, wherein the last antenna feed parameter vector is the antenna feed parameter vector obtained after searching along the last search direction in the search direction set i.

[0069] In some implementations, the difference vector between the initial antenna feed parameter vector and the last antenna feed parameter vector can be calculated using the following formula (1).

[0070]

[0071] in, This is the initial antenna feed parameter vector. Let be the last antenna feed parameter vector, and d be the difference vector between the initial antenna feed parameter vector and the last antenna feed parameter vector.

[0072] After calculating the difference vector d between the initial antenna feed parameter vector and the last antenna feed parameter vector using the above formula (1), the difference vector d can be used as a new replacement search direction to update and replace the search direction in the search direction set i, so as to obtain a new search direction set i+1, which is used for the iterative search of the antenna feed parameter vector in the i+1th iteration.

[0073] S302, based on the average RSRP value, obtain the target search direction with the fastest decrease in RSRP value on the search direction set i.

[0074] The greater the decrease in the average RSRP value corresponding to the search direction, the faster the RSRP value decreases in that search direction. Therefore, based on the decrease in the average RSRP value corresponding to each search direction, the target search direction with the fastest decrease in RSRP value on the search direction set i can be determined.

[0075] Alternatively, the maximum decrease in RSRP value on search direction set i can be calculated using the following formula.

[0076]

[0077] in, Antenna feed parameter vector The average RSRP value, Antenna feed parameter vector The average RSRP value, Δ m The maximum decrease in RSRP value on the search direction set i.

[0078] According to the above formula (2), the antenna feed parameter vector is calculated sequentially along the direction set i{e1, e2, ..., e n When performing a one-dimensional search, the maximum decrease in the average RSRP value is the search direction corresponding to this maximum decrease in the average RSRP value. This direction is denoted as S. m .

[0079] S303, in response to the search direction set i satisfying the search direction replacement condition, the target search direction is updated to the replacement search direction to obtain the search direction set i+1. The search direction replacement condition can be determined according to the actual situation and is not limited here.

[0080] In this embodiment of the disclosure, after obtaining the target search direction, it can be determined whether the search direction set i satisfies the search direction replacement condition. If so, the target search direction S is changed. m Update to replace search direction d; otherwise, do not perform the search direction replacement operation.

[0081] For example, in response to the search direction set i satisfying the search direction replacement condition, if the target search direction S m For the search direction set i{e1, e2, ..., e n If we consider e2 in the set of search directions, then we can update the search direction e2 to replace the search direction d, thus obtaining the search direction set i+1{e1, d, ..., e2}. n If the search direction set i does not meet the search direction replacement condition, no search direction replacement operation is performed.

[0082] In this embodiment, the difference vector between the initial antenna feed parameter vector and the last antenna feed parameter vector is obtained as a new replacement search direction. Based on the average RSRP value, the target search direction with the fastest decrease in RSRP value on the search direction set i is obtained. In response to the search direction set i satisfying the search direction replacement condition, the target search direction is updated to the replacement search direction to obtain the search direction set i+1. In this embodiment, the search directions in the search direction set are replaced and updated based on the search direction replacement condition, realizing the adaptive update of the search direction set and providing a new search direction set for the next round of antenna feed parameter vector iteration update, thereby realizing the adaptive update of antenna feed parameters.

[0083] Figure 4 This is a flowchart illustrating a method for updating antenna parameters according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 4 The process of determining whether the search direction set i satisfies the search direction replacement condition includes the following steps:

[0084] S401, based on the last antenna feed parameter vector and the initial antenna feed parameter vector, obtain the antenna feed parameter vector of the reflection point.

[0085] Alternatively, the antenna feed parameter vector at the reflection point can be calculated using the following formula (3).

[0086]

[0087] in, The antenna feed parameter vector at the reflection point. This is the initial antenna feed parameter vector. This is the last antenna feed parameter vector.

[0088] S402, obtain the average RSRP value of the reflection point corresponding to the antenna feed parameter vector of the reflection point.

[0089] After obtaining the antenna feeder parameter vector of the reflection point, the cell antenna can be adjusted based on the antenna feeder parameter vector of the reflection point. Then, the measurement report reported by the terminal device can be received, and the average RSRP value of the reflection point corresponding to the antenna feeder parameter vector of the reflection point can be obtained based on the measurement report.

[0090] In some implementations, the RSRP value of the antenna feed parameter vector at the reflection point is obtained, and then the RSRP value is weighted and summed based on certain weights to obtain the corresponding average RSRP value of the reflection point.

[0091] In some implementations, the RSRP value of the antenna feed parameter vector at the reflection point is obtained, and then the average value of the RSRP values ​​is taken as the average RSRP value of the reflection point.

[0092] S403, based on the average RSRP value and the average RSRP value of the reflection point, determine whether the search direction set i satisfies the search direction replacement condition.

[0093] Optionally, the following formula (4) can be used to determine whether the search direction set i satisfies the search direction replacement condition.

[0094] and

[0095] in, The last antenna feed parameter vector The average RSRP value, Initial antenna feed parameter vector The average RSRP value, The average RSRP value of the reflection point corresponding to the antenna feed parameter vector at the reflection point, Δ m The maximum decrease in RSRP value on the search direction set i.

[0096] If the initial antenna feed parameter vector Average RSRP value and last antenna feed parameter vector If the average RSRP value of the reflection point and the average RSRP value of the reflection point satisfy the above formula (4), then the search direction set i is determined to satisfy the search direction replacement condition; if the initial antenna feed parameter vector Average RSRP value and last antenna feed parameter vector If the average RSRP value of the i-th and the average RSRP value of the reflection point do not satisfy the above formula (4), then the search direction set i is determined to not satisfy the search direction replacement condition.

[0097] In this embodiment, the reflection point antenna parameter vector is obtained based on the last antenna parameter vector and the initial antenna parameter vector. The average RSRP value of the reflection point corresponding to the reflection point antenna parameter vector is then obtained. Based on the average RSRP value and the average RSRP value of the reflection point, it is determined whether the search direction set i satisfies the search direction replacement condition. This embodiment provides a search direction replacement condition, providing a basis for determining whether the search direction needs to be replaced.

[0098] Figure 5 This is a flowchart illustrating a method for updating antenna parameters according to an embodiment of the present disclosure. Based on the above embodiment, as follows... Figure 5 As shown, the method includes the following steps:

[0099] S501 adjusts the antenna of the target cell based on the acquired antenna feeder parameter vector.

[0100] During the iterative update of the antenna feeder parameter vector of the target cell, the updated antenna feeder parameter vector can be obtained. Then, based on each antenna feeder parameter in the updated antenna feeder parameter vector, the antenna of the target cell can be adjusted, such as the RSRP, downtilt angle, azimuth angle, angle of arrival, and transmit power of the target cell antenna.

[0101] S502 receives measurement reports from terminal devices within the target cell.

[0102] The target cell may include multiple terminal devices for uploading measurement reports to network devices.

[0103] For each pair of antennas in the target cell that are adjusted, the terminal equipment in the target cell will report a measurement report.

[0104] S503, based on the measurement report, obtain the average RSRP value corresponding to the antenna feeder parameter vector.

[0105] After receiving a measurement report from a terminal device within the target cell, the network device can parse the report, generate a parsing result, determine whether the measurement report includes an available angle of arrival (Angle of Arrival), and then obtain the average RSRP value corresponding to the antenna feeder parameter vector based on the judgment result. The Angle of Arrival can include both horizontal and vertical angles of arrival.

[0106] Optionally, in response to the measurement report not including the available angle of arrival, the RSRP value reported by the terminal device is obtained from the measurement report, and the average RSRP value corresponding to the antenna feeder parameter vector is obtained by averaging the reported RSRP values.

[0107] Optionally, in response to the measurement report including the available angle of arrival, the reported RSRP value and the reported angle of arrival are obtained from the measurement report, and based on the reported angle of arrival, the RSRP value reported by the terminal device is weighted and averaged to obtain the average RSRP value corresponding to the antenna feeder parameter vector.

[0108] It should be noted that the RSRP value and angle of arrival reported by the terminal device in the target cell can be multiple, which can be represented as [r1, r2, ..., r m ] and [A1,A2,…A m ], where m is a positive integer representing the total number of reported RSRP values ​​or the total number of angles of arrival.

[0109] In this embodiment, the antenna of the target cell is adjusted based on the acquired antenna feeder parameter vector. A measurement report reported by a terminal device within the target cell is received, and the average RSRP value corresponding to the antenna feeder parameter vector is obtained based on the measurement report. This embodiment achieves real-time dynamic adjustment of the cell antenna by adjusting the antenna of the target cell based on the acquired antenna feeder parameter vector. The average RSRP value corresponding to the antenna feeder parameter vector is obtained based on the measurement report, providing data support for subsequent updates to the search direction set.

[0110] Figure 6 This is a flowchart illustrating a method for updating antenna parameters according to an embodiment of the present disclosure. Based on the above embodiment, it further incorporates... Figure 6 The process of calculating the average RSRP value corresponding to the antenna feeder parameter vector by weighting the RSRP values ​​reported by the terminal device based on the reported angle of arrival is explained, including the following steps:

[0111] S601, divide the reported angle of arrival into intervals to obtain the angle of arrival intervals.

[0112] It should be noted that the method for dividing the reported angle of arrival into intervals can be determined according to the actual situation, and no restrictions are imposed here.

[0113] Optionally, the maximum and minimum angles of arrival can be obtained from the reported angles of arrival, and the reported angles of arrival can be divided into intervals based on the maximum and minimum angles of arrival to obtain the angle of arrival intervals.

[0114] In some implementations, the difference between the maximum and minimum angle of arrival is calculated, and the number of angle of arrival intervals is set to K (positive integers). The difference between the maximum and minimum angle of arrival is divided into K equal parts, where each part is an angle of arrival interval. In this way, the reported angle of arrival is divided into K angle of arrival intervals of equal size.

[0115] In some implementations, the size of the angle of arrival interval is pre-defined. Starting from the smallest angle of arrival, the angle of arrival interval is used as the interval to divide the reported angle of arrival until the last angle of arrival interval includes the largest angle of arrival, and the division ends. In this way, the reported angle of arrival can be divided into multiple angle of arrival intervals.

[0116] S602, obtain the number of arrival angles within the arrival angle interval.

[0117] S603, based on the number of angles of arrival within the angle of arrival interval and the total number of reported angles of arrival, determine the weight corresponding to the angle of arrival interval, wherein the weight of the angle of arrival interval is the weight of the angles of arrival within the angle of arrival interval.

[0118] Optionally, the ratio of the number of angles of arrival within the angle of arrival interval to the total number of reported angles of arrival can be determined as the weight corresponding to the angle of arrival interval.

[0119] In some implementations, the number of arrival angles in each arrival angle interval can be converted into a probability value between 0 and 1 using the following formula (5), and this probability value can be used as the weight corresponding to the arrival angle interval, that is, the weight of the arrival angles in the arrival angle interval.

[0120]

[0121] Where, count k This represents the number of arrival angles falling within the k-th arrival angle interval, where k is a positive integer, m represents the total number of arrival angles, and prob k,j Let j represent the probability (weight) of the angle of arrival numbered j within the k-th angle of arrival interval, where j = [0, 1, ..., count]. k ].

[0122] It should be noted that all angles of arrival have the same probability in each angle of arrival interval, meaning that all angles of arrival have the same weight in each angle of arrival interval.

[0123] S604, based on the weight of the angle of arrival, weights the RSRP values ​​reported by terminal devices belonging to the same terminal device as the angle of arrival to obtain the average RSRP value corresponding to the antenna feeder parameter vector.

[0124] Alternatively, the average RSRP value corresponding to the antenna feed parameter vector can be calculated using the following formula (6).

[0125]

[0126] Where K is the number of angle-of-arrival intervals, r k,j Let j be the RSRP value of the k-th arrival angle interval, where k is a positive integer and j = [0, 1, ..., count]. k ], count k This represents the number of arrival angles that fall within the k-th arrival angle interval, prob k,j This represents the probability (weight) of the angle of arrival numbered j within the k-th angle of arrival interval. This represents the average RSRP value corresponding to the antenna feed parameter vector.

[0127] As can be seen from the above formula (6), firstly, the reported RSRP values ​​corresponding to each angle of arrival (i.e., belonging to the same terminal device as the angle of arrival) are weighted and summed, and then the results of the weighted summation of the reported RSRP values ​​corresponding to all angles of arrival are summed to obtain the average RSRP value corresponding to the antenna feeder parameter vector.

[0128] Furthermore, based on the above embodiments, the process of averaging the reported RSRP values ​​to obtain the average RSRP value corresponding to the antenna feeder parameter vector is explained as follows:

[0129] If the measurement report reported by the terminal device in the target cell does not include the available angle of arrival, the RSRP value reported by the terminal device is obtained from the measurement report, and the average RSRP value corresponding to the antenna feeder parameter vector is calculated by the following formula (7).

[0130]

[0131] Where K is the number of angle-of-arrival intervals, r k,j This represents the RSRP value numbered j in the k-th angle of arrival interval, where k is a positive integer and j = [0, 1, ..., count]. k ], count k This represents the number of angles of arrival falling within the k-th angle of arrival interval, where m represents the number of RSRP values, and prOB. k,j This represents the probability (weight) of the angle of arrival numbered j within the k-th angle of arrival interval. This represents the average RSRP value corresponding to the antenna feed parameter vector.

[0132] It should be noted that in other embodiments of this disclosure, the average RSRP value of the reflection point corresponds to the antenna feed parameter vector of the reflection point. It can be calculated using the above formula (6) or formula (7).

[0133] In this embodiment, the reported angle of arrival (AUR) is divided into intervals to obtain AUR intervals. The number of AURs within each interval is obtained.
