Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a base station energy-saving management method and device. Background Art

[0002] In recent years, the rapid development of mobile communication technology, particularly the deployment of fifth-generation mobile communication systems, has significantly increased network capacity, speed, and connection density. However, as a core component of network infrastructure, the energy consumption of base stations has become a key factor restricting network construction and operating costs for telecommunications operators.

[0003] To address this challenge, various base station energy-saving technologies have emerged, including symbol shutoff, channel shutoff, carrier shutoff, and base station dormancy. These methods aim to reduce base station energy consumption and improve the economic and environmental friendliness of network operations. Symbol shutoff is a widely adopted energy-saving strategy that allows base stations to temporarily shut down their power amplifiers based on actual data transmission needs, thereby avoiding the energy consumed by idle amplifiers when no data is being transmitted. The key to this technology lies in identifying and determining which time slots can safely undergo symbol shutoff without negatively impacting network quality of service. However, existing symbol shutoff technologies have limitations and fail to fully consider the inter-cell interference issues caused by symbol shutoff in multi-cell environments. In dense network deployments, interference coordination between multiple base stations becomes particularly critical. Improper symbol shutoff strategies can exacerbate inter-cell interactions, leading to degraded signal quality for edge users, thus impacting overall network performance and user experience. Current energy-saving algorithms often rely on fixed cell traffic load indicators and lack the ability to dynamically adjust the symbol shutoff bitmap during energy-saving periods, limiting their effectiveness in dynamically changing network environments.

[0004] To address the above-mentioned problems, no effective solutions have been proposed so far. Summary of the Invention

[0026] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0027] It should be noted that the terms "first", "second", etc. in the specification, claims, and drawings of the present application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0028] In order to better understand the embodiments of the present application, some nouns or terms that appear in the description of the embodiments of the present application are first translated and explained as follows:

[0029] PRB (Physical Resource Block) utilization: In mobile communication networks, this refers to the proportion of physical resource blocks (PRBs) actually used for data transmission within a specific time window. A PRB is the basic unit of resource allocation, consisting of 12 consecutive subcarriers in the frequency domain and a time slot in the time domain (typically 0.5 milliseconds or 1 millisecond, depending on the system configuration). This metric is crucial for network operators because it reflects the efficiency of network resource usage and network load. A high PRB utilization rate may indicate that the network is under high load, potentially requiring additional resources to meet user demand or optimizing resource allocation strategies for improved efficiency. Under low load conditions, a low PRB utilization rate allows base stations to implement energy-saving measures (such as symbol and channel shutdown). By temporarily shutting down underutilized resource blocks, base station energy consumption can be effectively reduced, thereby lowering operating costs.

[0030] Example 1

[0031] According to an embodiment of the present application, a base station energy-saving management method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] Figure 1 is a flow chart of a base station energy-saving management method provided in accordance with an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps:

[0033] Step S102: obtaining first load data of each of a plurality of cells covered by the base station within a preset historical time period, and obtaining interference neighboring cell information of each cell;

[0034] Step S104: Analyze the first load data of each cell using the load forecasting model to obtain the second load data of each cell within the target time period;

[0035] Step S106, dividing the target time period into a plurality of symbol-off bitmap periods;

[0036] Step S108: Within each symbol-off bitmap period, for each cell, determining the number of required time slots for data transmission of the cell based on the second load data of the cell within the symbol-off bitmap period, and determining, based on the required number of time slots and interference neighboring cell information of multiple cells, a candidate time slot corresponding to the cell that satisfies a preset transmission interference requirement from multiple time slots corresponding to the symbol-off bitmap period;

[0037] Step S110 , determining a time slot allocation strategy for each cell within the symbol off bitmap period according to the required time slot quantity and the candidate time slots corresponding to each cell, and adjusting the symbol off bitmap of each cell based on the time slot allocation strategy.

[0038] The following describes the various steps of the base station energy-saving management method in conjunction with a specific implementation process.

[0039] As an optional implementation method, the duration of the symbol-off bitmap period can be determined in the following manner: obtaining the pre-configured minimum scheduling period of the delay-sensitive service and the pre-configured transmission period of the synchronization signal block; determining the smaller value of the preset multiple of the transmission period of the synchronization signal block and the minimum scheduling period of the delay-sensitive service as the duration of the symbol-off bitmap period.

[0040] First, obtain the network's preconfigured minimum scheduling period for delay-sensitive services and the synchronization signal block (SSB) transmission period. These parameters reflect the network's scheduling requirements for delay-sensitive services and the SSB frequency. These two parameters are defined during network architecture design and reflect the network's scheduling requirements for delay-sensitive services and the SSB frequency.

[0041] Specifically, we can use the formula min(T sensitive ,P SSB ) determines the duration of the symbol off bitmap period, where P SSB is a preset multiple of the transmission period of the synchronization signal block, T sensitive is the minimum scheduling period for delay-sensitive services. Assuming that in voice services, T sensitive=20ms, and P SSB =30ms, then the symbol off bitmap period T bitmap The value should be 20ms because it is the smaller of the two values ​​and can meet the scheduling requirements of delay-sensitive services without too frequent symbol shutdown bitmap configuration.

[0042] Finally, the information of the symbol shutdown bitmap will be bitmap This means that in each T bitmap Within a period, the bitmap indicates which time slots can be symbol-off and which need to remain active to support various communication needs in the network, including latency-sensitive services. The bitmap period should be selected to ensure that service scheduling requirements are met while minimizing ineffective power amplifier operation, thereby achieving energy conservation goals.

[0043] This method for determining the symbol-off bitmap period not only ensures the continuity and low latency of delay-sensitive services, but also effectively reduces the control overhead during the symbol-off process, improving the efficiency of energy-saving strategies. This design fully considers the diverse communication needs within the network, flexibly adapting to various service scenarios and ensuring that energy-saving operations do not sacrifice the user experience.

[0044] As an optional implementation, the load data of each cell can be predicted in the following manner: for any cell, the first load data of the cell is input into the load prediction model for analysis, and the second load data of the cell in multiple sub-time periods corresponding to the target time period predicted by the load prediction model is obtained, wherein the duration of each sub-time period is not less than the duration of the symbol off bitmap period.

[0045] In this application, we can use deep learning-based network load forecasting models, including but not limited to LSTM (Long Short-Term Memory) models, to predict load changes in each cell during non-sleep periods. This model can capture long-term dependencies in time series and is suitable for short-term prediction of network traffic, with high prediction accuracy.

[0046] Specifically, it is necessary to collect the initial load data of each cell over a period of time, including but not limited to data traffic, user activity, and wireless resource utilization. The collected historical load data can be preprocessed, including but not limited to data cleaning, standardization, and characterization, to eliminate noise, handle missing values, and extract key features that are helpful for prediction.

[0047] For any cell, the preprocessed first load data is fed into a trained LSTM model for analysis. The model then predicts the second load data for that cell in each sub-period (the duration of each sub-period is the output granularity of the load forecast, such as 15 minutes) within a target time period (e.g., the next 24 hours) based on historical patterns. It is important to note that the duration of each sub-period should be no less than the duration of the symbol-off bitmap period to ensure that the prediction results can adapt to the adjustment period of the symbol-off strategy.

[0048] For a load forecast output granularity (sub-period), the load remains almost constant during this time. The relevant data of the symbol shutdown bitmap in the sub-period calculated based on the load is fixed. Therefore, when the length of the sub-period is a multiple of the symbol shutdown bitmap period, this sub-period can be used as an energy-saving adjustment period. The symbol shutdown bitmaps corresponding to multiple symbol shutdown bitmap periods within the energy-saving adjustment period are all the same and do not need to be adjusted. In the next energy-saving adjustment period, the load information may change, and the system can update the symbol shutdown bitmap according to the changed load information.

[0049] The LSTM model introduced in this process enables more accurate network load forecasting, thereby guiding the adjustment of energy-saving strategies. During non-sleep periods, by properly setting the energy-saving adjustment cycle, the dynamic adjustment of the symbol power-off bitmap can match network load changes. This not only meets energy-saving requirements but also avoids adverse effects on user service quality, achieving the dual goals of energy conservation and emission reduction while improving user experience.

[0050] After the symbol-off bitmap period is determined, the target time period may be divided into a plurality of symbol-off bitmap periods according to the duration of the symbol-off bitmap period.

[0051] As an optional implementation method, the required number of time slots for data transmission in each cell can be determined in the following manner: for any cell, determine the PRB utilization rate and the corresponding number of delay-sensitive users of the cell within the symbol-off bitmap period from the second load data; obtain the first number of non-broadcast downlink time slots corresponding to the symbol-off bitmap period, the pre-configured minimum scheduling period for delay-sensitive services, and the pre-configured maximum number of scheduled users corresponding to a single time slot; determine the required number of time slots for data transmission in the cell based on the symbol-off bitmap period, the PRB utilization rate, the number of delay-sensitive users, the first number of non-broadcast downlink time slots, the minimum scheduling period for delay-sensitive services, and the maximum number of scheduled users corresponding to a single time slot.

[0052] Under standard configurations, a symbol-off bitmap period has 35 downlink time slots. Excluding broadcast time slots, the number of non-broadcast downlink time slots is 34. When calculating the required number of time slots for data transmission in each cell, PRB utilization reflects the utilization of the physical resource blocks within the cell and is a key factor in determining the number of required time slots. The number of delay-sensitive users (DSUs) refers to the number of users in a cell that are extremely sensitive to latency, such as voice users. Their service experience is directly impacted by the scheduling period. The maximum number of users scheduled per time slot defines the maximum number of users that a base station can schedule within a time slot. This is dependent on the cell's hardware capabilities and scheduling algorithm. The minimum scheduling period for delay-sensitive services is the shortest scheduling period required to ensure user-perceived quality of service for these services. Any scheduling delay beyond this period can degrade user experience. By comprehensively considering these factors, the number of time slots a cell needs to maintain active within a specific period can be accurately calculated, thereby meeting service requirements while minimizing unnecessary energy consumption. This approach solves the problem of overly extensive resource allocation and inability to adapt to rapid changes in network load in traditional energy-saving strategies through refined management and dynamic adjustment, thereby improving the overall energy efficiency of the network.

[0053] As an optional implementation method, the required number of time slots for each cell to transmit data is determined based on the symbol off bitmap period, PRB utilization, the number of delay-sensitive users, the first number of non-broadcast downlink time slots, the minimum scheduling period of the delay-sensitive service, and the maximum number of scheduled users corresponding to a single time slot. This can be achieved in the following way: For any cell, the required number of time slots for data transmission in the cell is determined according to the following formula:

[0054]

[0055] Where NactiveSlot represents the number of required time slots, ceil represents the rounding operation, NallSlot represents the first number of non-broadcast downlink time slots, PRB% represents the PRB utilization rate, α is the preset adjustment coefficient, and N sensitveUe represents the number of delay-sensitive users, T bitmap Indicates the symbol off bitmap period, N scheduleUe Indicates the maximum number of scheduled users corresponding to a single time slot, T sensitive Indicates the minimum scheduling period for delay-sensitive services.

[0056] When calculating the number of time slots required for data transmission in each cell, ceil represents the round-up operation. The first expression, ceil(NallSlot·PRB%·α), considers the total number of non-broadcast downlink time slots in the current cell multiplied by the PRB utilization and the adjustment factor to ensure that there are still enough time slots for data transmission while taking into account the total network load. The second expression is Focus on the needs of delay-sensitive users and ensure that such users are sensitive At least one scheduling opportunity is guaranteed within a certain period to maintain an unaffected service experience. α is a preset value greater than or equal to 1. It is dynamically adjusted based on the actual network operation status and energy-saving effects to achieve the optimal balance between energy saving and service quality. The initial value of α can be set based on experience, and the value of α can be appropriately increased or decreased by monitoring key network performance indicators.

[0057] As an optional implementation method, the candidate time slot corresponding to each cell that makes the transmission interference meet the preset requirements can be determined in the following manner, including: determining the number of interfering neighboring areas of the corresponding cell from the interfering neighboring area information of each cell, and counting the mode of the number of interfering neighboring areas of each cell; for any cell, obtaining the physical cell identifier of the cell; sorting and numbering the non-broadcast downlink time slots corresponding to the symbol off bitmap period in chronological order; for each non-broadcast downlink time slot, determining the first remainder of the non-broadcast downlink time slot number divided by the mode, and determining the second remainder of the physical cell identifier divided by the mode; if the first remainder is equal to the second remainder, the non-broadcast downlink time slot is used as the candidate time slot corresponding to the cell.

[0058] Assume that data is extracted from the interference neighbor information of all cells in the network, including the number of interference sources around each cell. This data can be obtained through information exchange between base stations or statistical data collected from the network management system. Then, the distribution of the number of interference neighboring cells in all cells is calculated to find the number of interference neighboring cells with the highest frequency, i.e. the mode. Assuming this mode is 3, the number of groups N is determined. group = 3. For any cell in the network, the unique physical cell identifier is obtained. The physical cell identifier is used to distinguish different cells in 5G networks and is transmitted in signals as part of the cell identity. By dividing time slots into multiple groups, it is relatively unlikely that cells in the same PCI modulo operation result group will transmit data in the same time slot, thereby reducing mutual interference between cells.

[0059] All non-broadcast downlink time slots within the symbol off bitmap period are numbered in the order of appearance to form a sequence number. Then, for each non-broadcast downlink time slot, the non-broadcast downlink time slot that satisfies the following mathematical relationship is determined as the candidate time slot of the cell:

[0060] mod(ID slot , N group )=mod(PCI,N group )

[0061] In the above formula, ID slot is the number of the non-broadcast downlink time slot, PCI is the physical cell identifier of the cell, N group is the number of groups determined by the distribution of the number of interfering neighbors.

[0062] The time slots that satisfy the above mathematical relationship are regarded as candidate time slots (available activation time slots) for the cell. This means that during the energy-saving adjustment period, the cell can give priority to these time slots to send data. On the basis of considering interference coordination, more accurate time slot allocation can improve the spectrum utilization efficiency of the network, allowing more data transmission tasks to be carried out within the same frequency band.

[0063] The following example uses the number of non-broadcast downlink time slots as 15. Table 1 records the candidate time slot numbers of some cells.

[0064] Table 1

[0065]

[0066] As an optional implementation method, the time slot allocation strategy of each cell within the symbol off bitmap period is determined based on the number of required time slots and candidate time slots corresponding to each cell, including: sorting multiple cells in ascending order according to the corresponding number of required time slots, and allocating time slots to each cell in sequence according to the following steps: for any cell, if the number of required time slots corresponding to the cell is not greater than the number of candidate time slots corresponding to the cell, selecting candidate time slots with the required number of time slots from the candidate time slots corresponding to the cell as the target time slots for data transmission of the cell, and in the selection process, giving priority to candidate time slots that are not allocated to other cells; if the number of required time slots corresponding to the cell is greater than the number of candidate time slots corresponding to the cell, determining the difference between the number of required time slots and the number of candidate time slots, and using all candidate time slots corresponding to the cell as the target time slots for data transmission of the cell, and selecting candidate time slots with the difference from the candidate time slots corresponding to the neighboring cells of the cell as the target time slots for data transmission of the cell, and in the selection process, giving priority to candidate time slots that are not allocated to the neighboring cells; wherein, if any time slot is allocated to multiple cells at the same time, the frequency resource blocks corresponding to the time slots are configured according to the inter-cell interference coordination strategy.

[0067] Taking the data shown in Table 1 as an example, as an optional implementation method, assuming that the number of required time slots corresponding to cell A, cell B, cell C and cell D are 2, 4, 7 and 4 respectively, then when executing the centralized allocation strategy, time slots are allocated to cell A first, and then cell B or cell D can be allocated, and finally cell C is allocated.

[0068] Figure 2 A schematic diagram of an optional time slot allocation is shown. Specifically, when allocating to cell A, since the number of required time slots for cell A is 2 and the number of candidate time slots is 5, two can be randomly selected from the 5 candidate time slots, for example, candidate time slots 1 and 4 can be directly selected and allocated to cell A; next, time slots are allocated to cell D. Since the number of required time slots for cell D is 4 and the number of candidate time slots is 5, and candidate time slots 1 and 4 have been allocated to cell A, the remaining candidate time slots 7, 10, and 13 can be allocated to cell D first, and then one can be randomly selected from candidate time slots 1 and 4, for example, candidate time slot 1 can be selected and allocated to cell D; then, time slots are allocated to cell B. The number of required time slots for cell B is 4, and the number of candidate time slots is 5. Therefore, 4 can be randomly selected from the 5 candidate time slots. For example, candidate time slots 2, 5, 8, and 11 can be allocated to cell B. Finally, time slots are allocated to cell C. Since the number of required time slots for cell C is 7 and the number of candidate time slots is 5, candidate time slots 3, 6, 9, 12, and 15 can all be allocated to cell C. To meet the required number of time slots for cell C, the remaining unoccupied candidate time slot 14 in its neighboring cell B can be first allocated to cell C, and then one can be randomly selected from the other candidate time slots of its neighboring cell B. For example, candidate time slot 11 can be selected and allocated to C.

[0069] According to the allocation method in the above example, there will be a situation where cell A and cell D share candidate time slot 1, and cell B and cell C share candidate time slot 11, that is, a candidate time slot is allocated to multiple cells at the same time. In order to reduce interference between cells, an inter-cell interference coordination strategy (ICIC, Inter-Cell Interference Coordination) can be adopted for candidate time slots allocated to multiple cells at the same time to adjust the use of frequency resource blocks in the time slot. For example, some FRBs (FRB Frequency Resource Blocks) can be allocated to one cell exclusively, while other FRBs can be allocated to another cell exclusively, or frequency division multiplexing can be used to allow different cells to send data on different subcarriers, thereby reducing mutual interference.

[0070] The above configuration method is based on a centralized configuration strategy. When the configuration method is a distributed configuration strategy, as an optional implementation method, after determining the candidate time slots corresponding to each cell so that the transmission interference meets the preset requirements from the multiple time slots corresponding to the symbol shutdown bitmap period based on the required time slot number and the interference neighboring area information of multiple cells, the time slot allocation of the cell within the symbol shutdown bitmap period can be achieved in the following way: for any cell, the required time slot number and candidate time slots corresponding to the cell are sent to the cell, wherein the cell is used to determine the target time slot for transmitting data according to the following steps: if the required time slot number corresponding to the cell is not greater than the candidate time slot number corresponding to the cell, select the candidate time slots with the required time slot number from the candidate time slots corresponding to the cell as the target time slot for transmitting data for the cell. During the selection process, the allocation status of the corresponding candidate time slots is obtained from other cells corresponding to each candidate time slot, and the candidate time slots that are not allocated to other cells are given priority; if the number of required time slots corresponding to the cell is greater than the number of candidate time slots corresponding to the cell, the difference between the number of required time slots and the number of candidate time slots is determined, and all candidate time slots corresponding to the cell are used as the target time slots for data transmission of the cell, and the candidate time slots with the difference number are selected from the candidate time slots corresponding to the neighboring cells of the cell as the target time slots for data transmission of the cell. During the selection process, the allocation status of each candidate time slot of the neighboring cells is obtained, and the candidate time slots that are not allocated to the neighboring cells are given priority; among them, if any time slot is allocated to multiple cells at the same time, the multiple cells are used to configure the frequency resource blocks corresponding to the time slot according to the inter-cell interference coordination strategy.

[0071] In a distributed configuration, each cell allocates time slots based on the relationship between the number of required time slots and the number of candidate time slots. To avoid interference between cells, cells can inquire about the allocation status of candidate time slots in neighboring cells before allocating time slots for themselves. After understanding the allocation status, the actual allocation rules are similar to those of the centralized allocation strategy described above and will not be further explained here. If sharing a candidate time slot is unavoidable, an ICIC strategy will be introduced for the shared candidate time slot to reduce interference between cells. When selecting a time slot, the cell will consider the allocation status of neighboring cells to avoid interference caused by the same time slot being reused by multiple cells. This method is particularly suitable for distributed base station systems. By enhancing local decision-making capabilities, it reduces the burden on the central controller and improves the adaptability and robustness of the network.

[0072] As an optional implementation, the above method also includes: for any cell, periodically monitoring the service quality indicator of the cell's transmitted data, wherein the monitoring period duration is greater than the symbol off bitmap period duration; when the service quality indicator is less than a preset indicator threshold, adjusting the adjustment coefficient α based on a preset adjustment step, and re-determining the time slot allocation strategy for the next symbol off bitmap period based on the adjusted adjustment coefficient α.

[0073] Assuming the current symbol-off bitmap period is 15 minutes and the monitoring period is set to 1 hour, this allows the impact of short-term energy-saving strategies on long-term service quality to be captured while avoiding overly frequent adjustments. At the end of the monitoring period, the network evaluates the service quality indicators of each cell. If a cell's indicator is found to be below expectations (for example, a throughput drop exceeding a preset threshold), the system automatically increases the value of α, for example, by 0.1.

[0074] Subsequently, based on the updated α value, the network recalculates the number of time slots required for each cell during the next symbol-off bitmap period. If the original calculation was based on α = 1, increasing α to 1.1 may mean that each cell needs to activate more time slots to support higher service demands, reducing the number of symbols turned off, thereby improving service quality, but may also result in reduced energy savings.

[0075] Through this monitoring and feedback mechanism, the network can flexibly adjust symbol shutdown policies to adapt to changing service demands and network conditions, ensuring that ideal energy savings and service quality are maintained under all circumstances. This simple and efficient approach effectively addresses service quality fluctuations caused by energy-saving measures, providing network operators with a powerful tool to optimize network operations and reduce costs.

[0076] Through the above steps, the cell load is accurately predicted and combined with interference coordination to achieve intelligent energy saving of the base station. First, by collecting historical load data and using advanced load prediction models (including but not limited to deep learning and machine learning algorithms), the load changes in the future target time period are predicted, which helps to plan the energy consumption management of the base station in advance. Secondly, the target time period is subdivided into multiple symbol shutdown bitmap cycles. In each cycle, the working time slot of the cell is dynamically adjusted according to the predicted load data and the interference information between cells to reduce unnecessary energy consumption. Finally, by adjusting the symbol shutdown bitmap, that is, controlling the shutdown of the base station transmitter in a specific time slot to reduce power consumption while ensuring service quality, the technical problems of the traditional base station energy-saving management strategy mode being fixed, low in flexibility, and prone to mutual interference between cells are solved.

[0089] As an optional implementation, the time slot analysis module can determine the required number of time slots for each cell to transmit data in the following manner: for any cell, determine the PRB utilization and the corresponding number of delay-sensitive users of the cell within the symbol-off bitmap period from the second load data; obtain the first number of non-broadcast downlink time slots corresponding to the symbol-off bitmap period, the pre-configured minimum scheduling period for delay-sensitive services, and the pre-configured maximum number of scheduled users corresponding to a single time slot; determine the required number of time slots for the cell to transmit data based on the symbol-off bitmap period, the PRB utilization, the number of delay-sensitive users, the first number of non-broadcast downlink time slots, the minimum scheduling period for delay-sensitive services, and the maximum number of scheduled users corresponding to a single time slot.

[0095] The above configuration method is based on a centralized configuration strategy. When the configuration method is a distributed configuration strategy, as an optional implementation method, after determining the candidate time slots corresponding to each cell so that the transmission interference meets the preset requirements from the multiple time slots corresponding to the symbol shutdown bitmap period based on the required time slot number and the interference neighboring area information of multiple cells, the time slot allocation of the cell within the symbol shutdown bitmap period can be achieved in the following way: for any cell, the required time slot number and candidate time slots corresponding to the cell are sent to the cell, wherein the cell is used to determine the target time slot for transmitting data according to the following steps: if the required time slot number corresponding to the cell is not greater than the candidate time slot number corresponding to the cell, select the candidate time slots with the required time slot number from the candidate time slots corresponding to the cell as the target time slot for transmitting data for the cell.
