Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus, electronic device, and storage medium for adjusting frame structure. Background Technology

[0002] In wireless communication systems, based on the duplexing method employed, systems can be categorized into two types: Frequency Division Duplexing (FDD) and Time Division Duplexing (TDD). In FDD systems, uplink and downlink transmit data based on different frequency points, meaning uplink and downlink resources can be allocated independently. In TDD systems, uplink and downlink transmit data based on the same frequency point but at different times, staggering transmission and reception. Compared to FDD systems, TDD systems do not require paired frequencies and can be easily configured on fragmented frequency bands that are difficult to utilize in FDD systems, effectively improving spectrum utilization. Furthermore, TDD systems allow for flexible configuration of the uplink / downlink frame ratio according to service type, tailored to the uplink and downlink data transmission requirements of the system.

[0003] Specifically, the Long Term Evolution (LTE) TDD system predefines seven frame structures, while the uplink / downlink ratio frame structure can be fully customized in the New Radio (NR) TDD system. Therefore, even though user service behaviors and distributions differ across cells, the frame structure of each cell can still be flexibly adjusted based on actual service requirements.

[0004] However, after adjusting the frame structure of each cell to the desired frame structure, inconsistencies in uplink and downlink switching points between adjacent cells may occur due to the different frame structures used by the cells. This can lead to cross-slot interference, i.e., interference between uplink data transmitted by neighboring cells and downlink data transmitted by neighboring cells and uplink data transmitted by neighboring cells and the uplink data transmitted by neighboring cells. Ultimately, this results in a severe deterioration of the cell's service performance. Summary of the Invention

[0005] The main objective of this application is to propose a method, apparatus, electronic device, and storage medium for adjusting the frame structure, aiming to achieve that adjusting the frame structure does not cause cross-slot interference, thereby enabling flexible adjustment of the frame structure of each cell without being limited by cross-slot interference.

[0006] To achieve the above objectives, embodiments of this application provide a method for adjusting frame structure, the method comprising the following steps: obtaining the degree of frame structure correlation between target cells; the degree of frame structure correlation includes information characterizing the mutual interference and / or frame structure requirements of each target cell; clustering the target cells according to the degree of frame structure correlation to obtain several cell clusters; determining the frame structure corresponding to each cell cluster according to the uplink and downlink load information of the target cells in the cell clusters, so as to adjust the frame structure of each target cell in the cell clusters according to the frame structure.

[0007] To achieve the above objectives, this application also proposes a frame structure adjustment method, comprising: receiving a frame structure adjustment instruction, wherein the frame structure adjustment instruction carries a frame structure corresponding to each cell cluster generated by the frame structure adjustment method described above; and adjusting the frame structure of each target cell within the cell cluster to the frame structure corresponding to the cell cluster.

[0008] To achieve the above objectives, this application also proposes a frame structure adjustment device, comprising: an acquisition module for acquiring the frame structure correlation degree between target cells; the frame structure correlation degree includes information characterizing the mutual interference and / or frame structure requirements of each target cell; a cell cluster division module for clustering the target cells according to the frame structure correlation degree to obtain several cell clusters; and a frame structure determination module for determining the frame structure corresponding to each cell cluster according to the uplink and downlink load information of the target cells in the cell cluster, so as to adjust the frame structure of each target cell in the cell cluster according to the frame structure.

[0009] To achieve the above objectives, this application also proposes a frame structure adjustment device, comprising: a receiving module for receiving a frame structure adjustment instruction, the frame structure adjustment instruction carrying a frame structure corresponding to each cell cluster generated by the frame structure adjustment method described above; and an adjustment module for adjusting the frame structure of each target cell within the cell cluster to the frame structure corresponding to the cell cluster.

[0010] To achieve the above objectives, embodiments of this application also propose an electronic device, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the frame structure adjustment method as described in any of the preceding claims.

[0011] To achieve the above objectives, embodiments of this application also propose a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the frame structure adjustment method described in any of the above embodiments.

[0012] The frame structure adjustment method proposed in this application, after obtaining the frame structure correlation degree containing information characterizing the mutual interference and / or frame structure requirements of each target cell, clusters the target cells according to the frame structure correlation degree. That is, the target cells are clustered according to the mutual interference and / or frame structure requirements between each target cell to obtain cell clusters. Target cells with high mutual interference and / or similar frame structure requirements are clustered into the same cell cluster, while target cells with low mutual interference and / or inconsistent frame structure requirements are clustered into different cell clusters. Furthermore, the frame structure corresponding to each cell cluster is determined according to the uplink and downlink load information of the target cells in the cell cluster. The frame structure of each target cell in the cell cluster is then adjusted according to the frame structure. This achieves the determination and adjustment of the frame structure on a cell cluster basis, so that target cells in different cells can be configured with different frame structures, which is convenient to fit their own frame structure requirements as much as possible. Target cells in the same cell cluster are configured with the same frame structure, that is, the uplink and downlink handover points in the frame are the same, avoiding cross-time slot interference between these target cells.

[0023] As can be seen from the background technology, although adjusting the frame structure can meet the service requirements of each cell, it will always bring about cross-slot interference.

[0024] To address the aforementioned issues, this application provides a method for adjusting frame structure, comprising the following steps: obtaining the degree of frame structure correlation between target cells; the degree of frame structure correlation includes information characterizing the mutual interference and / or frame structure requirements of each target cell; clustering the target cells according to the degree of frame structure correlation to obtain several cell clusters; determining the frame structure corresponding to each cell cluster according to the uplink and downlink load information of the target cells in the cell clusters, so as to adjust the frame structure of each target cell in the cell clusters according to the frame structure.

[0025] The frame structure adjustment method proposed in this application, after obtaining the frame structure correlation degree containing information characterizing the mutual interference and / or frame structure requirements of each target cell, clusters the target cells according to the frame structure correlation degree. That is, the target cells are clustered according to the mutual interference and / or frame structure requirements between each target cell to obtain cell clusters. Target cells with high mutual interference and / or similar frame structure requirements are clustered into the same cell cluster, while target cells with low mutual interference and / or inconsistent frame structure requirements are clustered into different cell clusters. Furthermore, the frame structure corresponding to each cell cluster is determined according to the uplink and downlink load information of the target cells in the cell cluster. The frame structure of each target cell in the cell cluster is then adjusted according to the frame structure. This achieves the determination and adjustment of the frame structure on a cell cluster basis, so that target cells in different cells can be configured with different frame structures, which is convenient to fit their own frame structure requirements as much as possible. Target cells in the same cell cluster are configured with the same frame structure, that is, the uplink and downlink handover points in the frame are the same, avoiding cross-time slot interference between these target cells.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to enable readers to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments. The clustering of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0027] This application provides a frame structure adjustment method, applicable to electronic devices such as servers deployed with Mobile Edge Computing (MEC), servers deployed with network management software, and computers. Specifically, it can be applied to control devices in base stations to adjust the frame structure of cells for control of the base station. Figure 1 As shown, it specifically includes:

[0028] Step 101: Obtain the degree of correlation of frame structures between each target cell.

[0029] In this embodiment, the frame structure correlation degree includes information characterizing the mutual interference and / or frame structure requirements of each target cell. In some examples, the frame structure correlation degree includes one or a combination of the following: distance degree, interaction degree, cross-slot interference degree, and frame structure similarity degree. Specifically, the distance degree is used to evaluate the distance between target cells; the interaction degree is used to evaluate the frequency of service interactions between a cell and its neighboring cells; the frame structure similarity degree between cells is used to evaluate the similarity of uplink / downlink handover point locations in the frame structure; and the cross-slot interference information characterizes the degree of cross-slot interference currently experienced by the cell.

[0030] To facilitate a better understanding of the acquisition of frame structure correlation degree by those skilled in the art, the following will illustrate the acquisition of distance, interaction, cross-slot interference, and frame structure similarity as examples. It should be noted that in other examples, distance and cross-slot interference can be acquired simultaneously, and the weighted sum of distance and cross-slot interference can be used as the final frame structure correlation degree; alternatively, distance, interaction, cross-slot interference, and frame structure similarity can be acquired simultaneously, and the weighted sum of these factors can be used as the final frame structure correlation degree. These methods will not be elaborated upon here.

[0031] When the frame structure correlation degree is distance-based, the frame structure correlation degree between each target cell can be obtained as follows: obtain the geographical location information of each target cell, wherein the geographical location information of the base station can come from the network planning information in the pre-set area; determine the physical distance between each target cell based on the geographical location information; and determine the distance degree based on the physical distance between each cell.

[0032] In some examples, the geographical location information of each target cell is obtained primarily based on the geographical location relationship of the base stations corresponding to the target cells. Specifically, the engineering parameter information of the base stations corresponding to the target cells is obtained. Based on the base station's latitude, longitude, and azimuth angle in the engineering parameter information, the latitude and longitude of each target cell, i.e., its geographical location information, is determined. Here, the base station's azimuth angle is actually the azimuth angle of the cell relative to the base station. More specifically, the engineering parameter information of the base stations corresponding to the target cells and the forward coverage distance of the target cells are obtained. Based on the base station's latitude, longitude, and azimuth angle in the engineering parameter information and the forward coverage distance of the target cells, the latitude and longitude of each target cell, i.e., its geographical location information, is determined. The forward coverage distance is defined as follows: (e.g., ...) Figure 2 As shown, point A is the location indicated by the latitude and longitude of the base station determined based on the engineering parameters, and point B is the location indicated by the latitude and longitude of a cell under the coverage of the base station, determined based on the cell's forward coverage distance, the cell's latitude and longitude, and the azimuth angle. The distance between points A and B is related to the forward coverage distance of the cell. The forward coverage distance of the cell is obtained based on the positional relationship between the cell and neighboring cells in the network planning, such as by averaging the distances of the nearest multiple cells within the cell's azimuth angle range to obtain the forward coverage range.

[0033] In some cases, although the latitude and longitude obtained from the engineering parameters are the same for cells belonging to the same base station, the coverage direction characteristics of each cell are actually different. Therefore, when determining the distance measure that is adapted to each cell and is not completely consistent with each other, the engineering parameters alone cannot be used. Therefore, the distance measure can be determined based on the physical distance between each target cell as follows: the distance measure is determined based on the physical distance between each target cell and a first preset constraint relationship, the first constraint relationship including the following expression:

[0034] disDegree i，j =1 – distance i，j / baseDis i

[0035] Among them, disDegree i，j Let distance be the distance between the i-th target cell and the j-th target cell. i，j Let baseDis be the physical distance between the i-th target cell and the j-th target cell. i The inter-cell coverage reference distance for the i-th target cell, determined based on the physical distances between the i-th target cell and other target cells, is denoted as baseDis. i This represents the average or weighted average distance between the i-th target cell and other target cells.

[0036] It is understandable that the distance between two target cells determined by the first constraint relationship is negatively correlated with the physical distance between the two target cells. That is, the closer the physical distance between the two target cells is, the greater the distance between the two target cells is, and the farther the physical distance between the two target cells is, the smaller the distance between the two target cells is.

[0037] Of course, the above are just specific examples. In other examples, the first constraint could also be the distance degree disDegree between the i-th target cell and the j-th target cell. i，j =K / distance i，j distance i，j The physical distance between the i-th target cell and the j-th target cell, etc., will not be elaborated here.

[0038] It should be noted that the physical distance between target cells can also be data recorded during network deployment, user-uploaded data when frame structure adjustment is required, or the cell location can be determined based on MR, Timing Advance (TA) and other information reported by terminals within the cell, and then the distance between each cell can be determined based on the cell location, etc., which will not be elaborated here.

[0039] When the frame structure correlation degree is the degree of interaction, the frame structure correlation degree between each target cell can be obtained in the following way: obtain the cell handover information of each target cell within the second preset period, wherein the cell handover information refers to the information of the terminal switching from one cell to another, which can be determined based on the handover relationship between cells or measurement report (MR), etc.; determine the degree of interaction between each target cell based on the cell handover information of each target cell.

[0040] In some examples, the interaction degree between target cells is determined based on the cell handover information of each target cell. This can be achieved as follows: determine the number of handovers between target cells based on the cell handover information of each target cell; determine the interaction degree based on the number of handovers between target cells and a second preset constraint relationship, the second constraint relationship including the following expression:

[0041]

[0042] Mutual i，j HoTime represents the interaction degree between the i-th target cell and the j-th target cell. i, M represents the number of handovers between the i-th and j-th target cells within the second preset period, and M represents the total number of target cells.

[0043] In other examples, the degree of interaction can also be determined according to the following expression:

[0044]

[0045] Mutual i，j HoTime represents the interaction degree between the i-th target cell and the j-th target cell. i, M represents the number of handovers between the i-th and j-th target cells within the second preset period, and M represents the total number of target cells.

[0046] Of course, the above are just specific examples of how to determine the degree of interaction. In other examples, it can be achieved through other expressions or processing methods, which will not be elaborated here.

[0047] When the frame structure correlation is frame structure similarity, it can be understood that this embodiment mainly solves the problem of cross-slot interference caused by different uplink and downlink handover points in the frames between different cells. After analysis, it was found that the different uplink and downlink handover points when adjusting the frame structure are due to different uplink and downlink load requirements. Therefore, in this embodiment, the main focus is on the impact of uplink and downlink load on the frame structure. Therefore, the degree of correlation of frame structures between target cells can be obtained as follows: The uplink and downlink load information of each target cell within a first preset period is obtained. This uplink and downlink load information refers to information measuring the amount of uplink and downlink transmitted data, such as uplink and downlink throughput, uplink and downlink transmission rate, or uplink and downlink physical resource block (PRB) utilization. Specifically, for NR systems, the uplink and downlink load information can include the uplink and downlink f-s and f-s of each beam. Cell handover information and uplink and downlink load information are obtained from key performance indicators (KPIs). The uplink and downlink load information within the first preset period is divided according to a preset time granularity to obtain the uplink and downlink load information of each target cell at different time periods. Based on the uplink and downlink load information at different time periods, the uplink and downlink load ratio of each target cell at different time periods is determined. Based on the uplink and downlink load ratio at different time periods, the frame structure corresponding to different time periods is determined, resulting in the frame structure sequence of each target cell. The frame structure sequence is a sequence composed of frame structures corresponding to different time periods within the first preset period. The frame structure similarity between target cells is determined based on the frame structure sequence. In this embodiment, the duration of a time period is defined as a time granularity. For example, if the first preset period is 30 days and the time granularity is hours, it can be divided into 30*24=720 time periods, each lasting one hour. It should be noted that this embodiment does not limit the duration or time granularity of the first preset period. The time granularity can be days, hours, minutes, seconds, etc., and the first preset period can be a quarter, a month, a week, etc. However, when dividing the first preset period according to the time granularity, it is necessary to obtain a sufficient number of time periods to reflect the dynamic changes in the cell frame structure requirements over time.

[0048] Of course, the first preset period can be divided into several third preset periods. Then, each third preset period can be further divided according to time granularity to determine the uplink and downlink load ratio sequence corresponding to each third preset period. Then, the average value of the uplink and downlink load ratios for the corresponding time periods of several third preset periods can be used to obtain the final uplink and downlink load ratio for determining the frame structure sequence. For example, if the first preset period is 30 days, it can be divided into 30 days. Then, the uplink and downlink throughput ratio for each hour of each day can be determined to obtain the uplink and downlink throughput ratio sequence for each day. The average value of the uplink throughput ratio for the 0-1 hour time period of the 30 days can be calculated to obtain the final uplink and downlink throughput ratio sequence.

[0049] In some examples, the uplink / downlink load ratio over a given period can be determined using the following expression:

[0050] ulDlRatio=ulThroughput / dlThroughput

[0051] Wherein, ulDlRatio represents the ratio of uplink to downlink load within a certain period, ulThroughput represents the uplink throughput within that period, and dlThroughput represents the downlink throughput within that period;

[0052] In some examples, determining the frame structure similarity between target cells based on the frame structure sequence can be achieved as follows: The target cells are clustered based on their centroids according to the frame structure sequence to obtain the centroid of each category; the centroid distance between the categories to which each target cell belongs after clustering is used as the frame structure similarity between the target cells. That is, the frame structure similarity between target cells can be determined by the following expression:

[0053]

[0054] Among them, frmSmilarity i,j std represents the frame structure similarity between the i-th target cell and the j-th target cell. i, std is the centroid sequence of the category to which the frame structure sequence of the i-th target cell belongs. i The k-th element, std j, std is the centroid sequence of the class to which the frame structure sequence of the j-th target cell belongs. j The k-th element represents the total number of elements in the centroid sequence, i.e., the total number of time periods contained within the first preset period. At this point, it can be observed that the frame structure similarity ranges from 0 to 1. The difference between frames belonging to the same frame structure is 1; the greater the difference between frame structures, the smaller the similarity value.

[0055] It should be noted that after determining the centroid, the frame structure similarity between two target cells can also be determined based on the cosine distance between the centroids of the frame structure sequences belonging to their respective categories. Specifically, the frame structure similarity can be determined using the following expression:

[0056]

[0057] Among them, frmSmilarity i,j std represents the frame structure similarity between the i-th target cell and the j-th target cell. i, std is the centroid sequence of the category to which the frame structure sequence of the i-th target cell belongs. i The k-th element, std j, std is the centroid sequence of the class to which the frame structure sequence of the j-th target cell belongs. j The k-th element, len represents the total number of elements in the centroid sequence, that is, the total number of time periods contained in the first preset period.

[0058] In other cases, the frame structure similarity between target cells can be determined based on the frame structure sequence, or by calculating the cosine similarity between the frame structure sequences of two target cells. That is, the frame structure similarity between target cells can be determined using the following expression:

[0059]

[0060] Among them, frmSmilarity i,j Let d be the frame structure similarity between the i-th target cell and the j-th target cell. i, Let d be the k-th element of the frame structure sequence of the i-th target cell. j, Let len ​​be the kth element of the frame structure sequence of the jth target cell, and let len ​​represent the total number of elements in the frame structure sequence, that is, the total number of time periods contained in the first preset period.

[0061] Of course, the above are just specific examples. In other examples, the frame structure similarity between target cells can be determined in other ways, which will not be elaborated here.

[0062] It is worth mentioning that the uplink and downlink load demand of the target cell is usually dynamic rather than static, and the uplink and downlink load of the same cell is different at different times. Accordingly, the frame structure of the demand is also different. Therefore, it is more accurate to use a time series, that is, a sequence composed of the uplink and downlink load ratios of each time period included in the first preset period, rather than a single data point, to dynamically describe the frame structure characteristics of each cell.

[0063] In other examples, the frame structure adjustment method, before determining the frame structure corresponding to different time periods based on the uplink / downlink load ratio in different time periods to obtain the frame structure sequence for each target cell, also includes: determining a candidate set of frame structures based on actual needs and service characteristics, such as determining a candidate set of frame structures {a first-class frame structure dominated by uplink, a second-class frame structure dominated by uplink, a first-class frame structure dominated by downlink, a second-class frame structure dominated by downlink, and a balanced uplink / downlink frame structure}. Correspondingly, determining the frame structure corresponding to different time periods based on the uplink / downlink load ratio in different time periods to obtain the frame structure sequence for each target cell can be achieved as follows: matching the frame structures corresponding to different time periods from the candidate set based on the uplink / downlink load ratio in different time periods to obtain the frame structure sequence. For example, if the uplink / downlink load ratio sequence of a certain cell is {1.3, 1.5, 3, 0.8, 0.5, 1, 1, 2.4}, and it is predefined that when the uplink / downlink load ratio is greater than 1.2 and less than 2, uplink-dominant first-type frames are used; when the uplink / downlink load ratio is greater than 2, uplink-dominant second-type frames are used; when the uplink / downlink load ratio is greater than 0.9 and less than 0.95, downlink-dominant first-type frames are used; when the uplink / downlink load ratio is less than 0.9, downlink-dominant second-type frames are used; and when the uplink / downlink load ratio is greater than 0.95 and less than 1.2, balanced uplink / downlink frames are used, then the frame structure sequence of this cell is {uplink-dominant first-type frame structure, uplink-dominant first-type frame structure, uplink-dominant second-type frame structure, downlink-dominant second-type frame structure, downlink-dominant second-type frame structure, balanced uplink / downlink frame structure, balanced uplink / downlink frame structure, uplink-dominant first-type frame structure}.

[0064] It should be noted that the frame structure candidate set can also be a set of frame structures predefined by the user. In particular, the frame structures defined in the frame structure candidate set can be several frame structures selected based on the service characteristics of the current cell.

[0065] It is worth mentioning that providing a candidate set of frame structures based on actual load requirements and business characteristics narrows the operation of determining the frame structure from matching several frame structures to matching from the candidate set of frame structures, thereby reducing the amount of computation, alleviating processing pressure, and improving processing efficiency.

[0066] When the frame structure correlation degree is the cross-slot interference degree, the frame structure correlation degree between each target cell can be obtained in the following way: obtain the cross-slot interference information between cells, where the cross-slot interference information can be represented by the proportion of PRBs affected by cross-slot interference; determine the cross-slot interference degree based on the cross-slot interference information.

[0067] It should be noted that the above explanation is mainly based on the premise that interaction degree, distance degree, and frame structure similarity need to be determined between every two cells. In other examples, interaction degree, distance degree, and frame structure similarity can also be calculated only between cells whose geographical distance is less than a preset distance value. It is understandable that interference and terminal cell handover are more likely to occur between cells with smaller geographical distances. This will not be elaborated on further here.

[0068] It should also be noted that when the frame structure adjustment method is applied to the control device within the base station, the base station involved in step 101 can be the base station to which the control device belongs, or it can be the base station to which the control device belongs and several base stations with which it has a communication connection. When the frame structure adjustment method is applied to the peripheral device, the base station involved in step 101 can be one or more base stations managed by the peripheral device, which will not be elaborated here.

[0069] It is worth mentioning that, when the frame structure correlation degree includes frame structure similarity, and at least one of distance, interaction, and cross-slot interference, after obtaining the frame structure correlation degree, cells are clustered according to the frame structure correlation degree to obtain cell clusters. This can group cells that interfere with each other greatly and have similar frame structure requirements into the same cell cluster, and cluster cells that interfere with each other little and have inconsistent frame structure requirements into different cell clusters. In this way, when determining and adjusting the frame structure on a cell cluster basis, it can not only meet the frame structure requirements of each cell, but also avoid cross-slot interference between cells because cells that interfere with each other, i.e., cells in the same cell cluster, are configured with the same frame structure, i.e., frames with the same uplink and downlink handover points. Furthermore, cells with inconsistent frame structure requirements, i.e., cells in different cell clusters, are assigned different frame structures that meet their respective requirements. Ultimately, it achieves the ability to adjust the frame structure of cells according to actual needs without causing cross-slot interference.

[0070] Step 102: Cluster the target cells according to the degree of correlation of the frame structure to obtain several cell clusters.

[0071] This embodiment does not limit the specific method of clustering processing; it can be graph clustering, DBSCN (Density-Based Spatial Clustering of Applications with Noise), NQ-DBSCN, etc.

[0072] To help those skilled in the art better understand step 102, the following explanation will use graph clustering as an example.

[0073] First, each target cell is treated as a node in a topology graph. An undirected edge is created between two target nodes corresponding to two target cells with frame structure association. Then, the degree of frame structure association between target cells is used as the edge weight and assigned to the corresponding edge. Next, based on the topology graph, clustering is performed according to the graph clustering algorithm to obtain several groups of cells, and each group of cells is a cell cluster.

[0074] Understandably, when the interaction and distance between the target cell and its neighboring cells are low, interference caused by different frame structures has little impact on overall performance. However, when the interaction between the target cell and its neighboring cells is high, cross-slot interference caused by different frame structures can significantly impact performance. Therefore, it is desirable to group cells with low interaction and distance into different cell clusters. This allows for the determination of different frame structures tailored to the specific needs of different target cells, while minimizing cross-slot interference. When the frame structures of a target cell are not highly similar to those of other target cells, grouping them into the same cell cluster and assigning them the same frame structure would not simultaneously meet the needs of different target cells, resulting in significant discrepancies. Therefore, it is desirable to group cells based on frame structure similarity into different cell clusters. In other words, graph clustering aims to group nodes with smaller edge weights into different clusters and nodes with larger edge weights into the same cluster.

[0075] It should also be noted that in the topology graph described above, there is only one edge between nodes corresponding to every two target cells with a frame structure relationship. In other cases, edges can be created between every two nodes. When edges are created only when there is a frame structure relationship, the topology graph is relatively simple, requires less processing, and is more efficient. Of course, creating an edge between every two cells will yield more accurate cell clusters. The processing method can be chosen according to actual needs, which will not be elaborated further here.

[0076] Specifically, cell clusters can be determined multiple times to adapt to the current service situation of each cell, better meet user needs, and improve user experience. During the process of determining cell clusters multiple times, if the frame structure correlation includes at least two of the following: distance, interaction, cross-slot interference, and frame structure similarity (i.e., a weighted summation is needed to represent the final frame structure correlation), the weights used in the summation can be continuously adjusted. Specifically, when determining cell clusters for the first time, the weights used in the summation are preset values. In subsequent cell cluster determinations, the current cross-slot interference, service status, etc., can be detected, and the weights can be adjusted according to certain rules based on the detected results. For example, when using a greedy algorithm for updates, if the cross-slot interference between target cells in different cell clusters exceeds a certain level and the service experience of the target cell deteriorates (e.g., throughput, scheduling rate decreases), the greedy algorithm is negatively incentivized; if the cross-slot interference is below a certain level, the greedy algorithm is positively incentivized. This continues until the greedy algorithm converges or reaches the threshold for the number of adjustments, at which point the weights used in the summation are no longer adjusted.

[0077] Understandably, the frame structure determined using the above method may still need further adjustment. Therefore, after determining the frame structure corresponding to each cell cluster based on the uplink and downlink load information of the target cell in the cell cluster, the frame structure adjustment method also includes: obtaining the current cross-slot interference information and current service performance data between target cells; if it is detected that the cell cluster needs to be updated based on the current cross-slot interference information and current service performance data, updating the cell cluster based on the current cross-slot interference information, so as to redetermine the frame structure corresponding to each cell cluster based on the updated cell cluster. This achieves real-time updates, making the determined frame structure more accurate and more in line with service requirements.

[0078] Step 103: Determine the frame structure corresponding to each cell cluster based on the uplink and downlink load information of the target cell in the cell cluster, so as to adjust the frame structure of each target cell in the cell cluster according to the frame structure.

[0079] In this embodiment, after the control device inside the base station determines the frame structure corresponding to each cell cluster, it generates corresponding instructions through internal information exchange to notify the cell or terminal to adjust the frame structure. When the peripheral device determines the frame structure to be configured, it notifies the base station of the frame structure to be configured through a predefined communication interface with the base station so that the base station can further adjust the frame structure.

[0080] It is understandable that after the frame structure to be configured is determined, the information of the target cell may change, which may cause the currently determined frame structure to no longer meet the service requirements. Therefore, after determining the frame structure corresponding to each cell cluster based on the uplink and downlink load information of the target cell in the cell cluster, the frame structure adjustment method also includes: obtaining the uplink and downlink load information and / or cell handover information of each target cell; and updating the cell cluster based on the currently obtained uplink and downlink load information and / or cell handover information of the target cell when the change in the uplink and downlink load information and / or cell handover information of at least one target cell exceeds a preset threshold.

[0081] Another aspect of this application embodiment provides a frame structure adjustment method, applied to a base station. For example... Figure 3 As shown, it specifically includes:

[0082] Step 301: Receive frame structure adjustment instruction, which carries the frame structure corresponding to each cell cluster.

[0083] It should be noted that the frame structure corresponding to each cell cluster is obtained according to the frame structure adjustment method provided in the previous embodiment.

[0084] Step 302: Adjust the frame structure of each target cell within the cell cluster to the frame structure corresponding to the cell cluster.

[0085] In this embodiment, for the LTE system, after receiving the structure adjustment instruction, the radio resource control (RRC) reconfiguration of the air interface is triggered; for systems such as NR that can flexibly adjust the frame structure, the frame structure conversion can be achieved through dynamic data scheduling without the need for reconfiguration through the air interface's RRC.

[0086] It is understandable that although cross-slot interference between cells can be detected through measurements by base stations and terminals, and interference can be avoided or eliminated to a certain extent through scheduling mechanisms in the time domain, frequency domain, or beam domain, cross-slot interference may still exist. Therefore, it is necessary to report the interference so that the frame structure can be adjusted to meet service requirements. Thus, after adjusting the frame structure of each target cell within a cell cluster to the frame structure corresponding to the cell cluster, the frame structure adjustment method also includes: detecting cross-slot interference in each target cell; and, if cross-slot interference is detected, acquiring cross-slot interference information and service performance data and reporting them.

[0087] To facilitate a better understanding by those skilled in the art of adjusting the frame structure provided in the embodiments of this application, the following will use the following examples... Figure 4The example shown illustrates a scenario with 3 base stations and 9 cells within the peripheral management area. The hexagonal areas marked with serial numbers represent the individual cells, the serial numbers represent the serial numbers of the individual cells, and the 3 black dots represent the locations of the 3 base stations.

[0088] First, we collect the latitude and longitude information of each base station, the azimuth information of the cell, the uplink and downlink throughput in the past week, and the number of times the terminal attempts to join and leave the cell and its neighboring cells.

[0089] Then, based on the number of cut-in and cut-out attempts within a week, the interaction degree among these 9 cells was determined. Only the interaction degree between cells with high interaction degree was retained, resulting in the following table:

[0090] 1 2 3 4 5 6 7 8 9 1 0.457 0.115 0.093 2 0.457 0.208 0.119 3 0.115 0.208 0.440 4 0.093 0.155 0.389 5 0.155 0.363 6 0.363 0.142 0.273 7 0.119 0.440 0.047 8 0.389 0.142 0.106 9 0.273 0.047 0.106

[0091] Table 1

[0092] In Table 1, the first row and first column respectively represent the following: Figure 4 The numbers of the nine cells shown represent the interaction degree between the i-th cell and the j-th cell, where i and j are both positive integers.

[0093] Based on the latitude and longitude information of each base station and the azimuth information of each cell, the distance between each cell is determined. Only the interaction between cells with high interaction is retained, resulting in the following table:

[0094] 1 2 3 4 5 6 7 8 9 1 0.75 0.81 0.56 2 0.75 0.72 0.55 3 0.81 0.72 0.65 4 0.56 0.83 0.45 5 0.83 0.24 6 0.24 0.56 0.62 7 0.55 0.65 0.5 8 0.45 0.56 0.23 9 0.62 0.5 0.23

[0095] Table 2

[0096] In Table 2, the first row and first column respectively represent the following: Figure 4 The numbers of the 9 cells shown represent the distance between the u-th cell and the v-th cell, where u and v are both positive integers.

[0097] For a given cell, based on the uplink and downlink throughput within the past week, the time window is divided into 7 days with a length of one day. The average uplink and downlink throughput for each day from 0:00 to 1:00, 1:00 to 2:00 to 23:00 to 24:00 is calculated to obtain 7 time series of uplink and downlink load ratio with a length of 24 and an hourly time granularity. Then, the average value of the first position of the 7 time series is calculated, the average value of the second position of the 7 time series is calculated, and so on, until the average value of the 24th position of the 7 time series is calculated to obtain the final time series {ulDlRatio0, ulDlRatio1, ..., ulDlRatio23}.

[0098] After obtaining the time series of 9 cells, based on the preset candidate set of frame structures {downlink as the main frame structure, uplink-downlink balanced frame structure, uplink as the main frame structure} and the preset mapping relationship from uplink-downlink load ratio to frame structure shown in the table below, 9 frame structure sequences {frame0, frame1, frame2...frame23} are obtained:

[0099]

[0100]

[0101] Table 3

[0102] In Table 3, the first row represents the various frame structures in the candidate frame structure set, and the second row represents the mapping conditions. Taking the second row as an example, when the uplink and downlink load ratio ulDlRatio of a certain period meets the condition ulDlRatio<preset threshold 1, the matched frame structure is the downlink main frame structure.

[0103] The resulting nine frame structure sequences were then processed using the k-means clustering algorithm, resulting in two classes: the first class containing cells 1, 2, 3, 7, and 8, and the second class containing cells 4, 5, 6, and 9. The similarity between the two classes was determined to be 0.58, meaning the frame structure similarity between any two cells from different classes is 0.58, while the frame structure similarity between cells from the same class is 1, meaning the frame structure similarity between any two cells is determined.

[0104] Assuming the cross-slot interference is 0, with the preset weights for distance (0.1), interaction (0.3), frame structure similarity (0.3), and cross-slot interference (0.3), the interaction between cells is shown in the table below:

[0105] 1 2 3 4 5 6 7 8 9 1 0.5707 0.5545 0.3933 2 0.5707 0.5368 0.4769 3 0.5545 0.5368 0.539 4 0.3933 0.5645 0.3899 5 0.5645 0.4083 6 0.4083 0.3982 0.5133 7 0.4769 0.539 0.3707 8 0.3899 0.3982 0.2956 9 0.5133 0.3707 0.2956

[0106] Table 4

[0107] In Table 4, the first row and first column respectively represent the following: Figure 4 The numbers of the 9 cells shown represent the weight sum between the s-th cell and the t-th cell, where s and t are both positive integers.

[0108] Furthermore, based on the weights shown in Table 4, we can obtain the following: Figure 5 The topological graph shown is then used to perform graph clustering algorithms. Figure 5 The topology graph shown is processed to obtain the following: Figure 6The diagram shown is of a cell cluster, where cell cluster 1 includes cells 1, 2, 3, 5, 6, and 7, and cell cluster 2 includes cells 4, 8, and 9.

[0109] Next, based on the overall uplink and downlink load of cells 1, 2, 3, 5, 6, and 7 and the mapping relationship shown in Table 3, it is determined that cell cluster 1 needs to select a downlink-dominant frame structure from the frame structure candidate set, and cell cluster 2 needs to select a balanced uplink and downlink frame structure from the frame structure candidate set.

[0110] Next, based on the above results, a corresponding frame structure adjustment instruction is generated and sent to the base station. After receiving the frame structure adjustment instruction, the base station changes the uplink and downlink frame structure ratio.
