[0003] The present application relates to the field of communication technology, and in particular to a communication control method, device, base station, and computer-readable storage medium. Background Art

[0004] Currently, in DSS (Dynamic Spectrum Sharing) scenarios and NR (New Radio) + LTE (Long Term Evolution) co-frequency scenarios, the PDSCH (Physical Downlink Shared Channel) of the NR terminal will be interfered with by the Common Reference Signal (CRS) of the neighboring LTE cell, which has a significant impact on downlink traffic. Therefore, it is necessary to consider NR's anti-interference solutions, such as rate matching.

[0005] In some cases, commonly used rate matching strategies include dynamic rate matching and static rate matching. Static rate matching uses a fixed RE (Resource Element) or symbol-level rate matching strategy for each serving cell. Dynamic rate matching also uses parameter configuration to implement different rate matching strategies under certain conditions. However, these two methods are not flexible enough to cope with changing interference scenarios and have poor interference mitigation effectiveness.

[0053] The following detailed description of some embodiments of the present application is provided in conjunction with the accompanying drawings. The following embodiments and features may be combined with each other unless they conflict. Please refer to Figure 4, which is a schematic flow chart of a communication control method provided by an embodiment of the present application. As shown in Figure 4, the communication control method includes steps S101 to S103.

[0054] Step S101: Acquire a first signal parameter of a serving cell where a user terminal is located and a second signal parameter of a neighboring cell of the serving cell.

[0055] It should be noted that the embodiment of the present application provides a communication control method that can be applied to DSS scenarios and NR+LTE co-frequency scenarios. The following will take these two scenarios as examples to illustrate how the base station controls the communication of the user terminal.

[0056] Exemplarily, the base station may collect the first signal parameter of the serving cell where the user terminal is located and the second signal parameter of the neighboring cell of the serving cell. The first signal parameter may include a first reference signal received power (RSRP). In the NR+LTE co-frequency scenario, the second signal parameter may include a second reference signal received power. In the DSS scenario, in addition to including the second reference signal received power, the second signal parameter may also include neighboring cell load information.

[0057] By acquiring the first signal parameters of the serving cell where the user terminal is located and the second signal parameters of the neighboring cell of the serving cell, the target grid can be determined based on the first signal parameters of the serving cell and the second signal parameters of the neighboring cell.

[0058] Step S102: Determine a target grid to be matched by the user terminal from a preset grid model according to the first signal parameter and the second signal parameter, where the grid model includes a plurality of grids.

[0059] In some embodiments, after obtaining the first signal parameters of the service cell where the user terminal is located and the second signal parameters of the neighboring cell of the service cell, the target grid matching the user terminal can be determined from a preset grid model based on the first signal parameters and the second signal parameters, and the grid model includes multiple grids.

[0060] It should be noted that, in the embodiment of the present application, different scenes correspond to different grid models, wherein the grid model includes multiple grids.

[0061] Please refer to Figure 5, which is a schematic diagram of a grid model provided in an embodiment of the present application. Figure 5 is a grid model corresponding to the NR+LTE co-frequency scenario. In the NR+LTE co-frequency scenario, the dimensions in the grid model can include signal strength and signal-to-interference ratio dimensions, and each grid corresponds to a rate matching method.

[0062] For example, as shown in Figure 5, in the NR+LTE co-frequency scenario, the target grid for the user terminal to match can be determined from the grid model based on the first reference signal received power and the second reference signal received power. For example, a first dimension interval of the first reference signal received power in the signal strength dimension can be determined, and a second dimension interval of the second reference signal received power in the signal-to-interference ratio dimension can be determined. Then, grid positioning can be performed in the grid model based on the first dimension interval and the second dimension interval to obtain the target grid.

[0063] Please refer to Figure 6, which is a schematic diagram of another grid model provided in an embodiment of the present application. Figure 6 is a grid model corresponding to a DSS scenario. In a DSS scenario, the dimensions in the grid model may include signal strength, signal-to-interference ratio, and neighboring cell load, with each grid corresponding to a rate matching method.

[0064] For example, as shown in Figure 6, in a DSS scenario, the target grid for the user terminal to match can be determined from the grid model based on the first reference signal received power, the second reference signal received power, and the neighboring cell load information. For example, the first dimension interval of the first reference signal received power in the signal strength dimension can be determined, the second dimension interval of the second reference signal received power in the signal-to-interference ratio dimension can be determined, and the third dimension interval of the neighboring cell load information in the neighboring cell load dimension can be determined. Then, grid positioning can be performed in the grid model based on the first dimension interval, the second dimension interval, and the third dimension interval to obtain the target grid.

[0065] Step S103: Schedule the user terminal according to the rate matching method corresponding to the target grid.

[0066] In some embodiments, after determining a target grid for matching the user terminal from a preset grid model based on the first signal parameter and the second signal parameter, the user terminal may be scheduled according to a rate matching method corresponding to the target grid.

[0067] For example, the rate matching mode corresponding to the target grid can be obtained, and the user terminal can be scheduled according to the rate matching mode corresponding to the target grid. Specific scheduling processes can be found in related technologies and are not limited here.

[0068] It should be noted that in the embodiment of the present application, the grid model can be pre-trained to match the rate matching mode for each grid in the grid model. The rate matching mode for each grid can be an RE-level rate matching mode or a symbol-level rate matching mode.

[0069] In the above embodiment, the target grid for matching the user terminal is determined from the grid model based on the first signal parameter and the second signal parameter, and the user terminal is scheduled according to the rate matching method corresponding to the target grid. Since the first signal parameter includes the reference signal receiving power and the second signal parameter includes the reference signal receiving power and the neighboring cell load information, it is possible to integrate signal parameters such as signal strength and interference strength when determining the rate matching method, thereby solving the problem of poor anti-interference effect of the rate matching strategy in the related technology, and can control the rate matching method more finely, thereby improving the anti-interference effect of the rate matching.

[0070] In the embodiment of the present application, the grid model is pre-trained, and how to train the grid model will be described in detail below.

[0071] Please refer to Figure 7, which is a schematic flowchart of the sub-steps of training a grid model provided in an embodiment of the present application. As shown in Figure 7, the training process of the grid model may include the following steps S201 to S204.

[0072] Step S201: construct an initial grid model.

[0073] In an embodiment of the present application, an initial grid model may be constructed. The initial grid model may include grids of multiple signal dimensions, each grid corresponding to a signal dimension in a different interval range.

[0074] For example, in an NR+LTE co-frequency scenario, the grid model can include a signal strength dimension and a signal-to-interference ratio dimension. For example, the signal strength dimension can be divided into K categories, and for each category of signal strength dimension, the signal-to-interference ratio dimension can be divided into M intervals. The values ​​of K and M can be set based on actual conditions, and the specific values ​​are not limited here.

[0075] In some embodiments, when K=3 and M=5, a non-equal interval division method can be adopted to divide the signal strength dimension into 3 intervals: RSRP(-inf,-110], RSRP(-110,-90], RSRP(-90,inf), and the signal-to-interference ratio dimension is divided into 5 intervals: sir(-inf,3], sir(3,10], sir(10,20], sir(20,30], sir(30,inf). Wherein, inf represents infinity. Then, the grids in the grid model are divided into two categories: grids corresponding to the RE-level rate matching method and grids corresponding to the symbol-level rate method. According to the signal strength dimension and the signal-to-interference ratio dimension, a total of K×M two-dimensional grids are generated in each category, and each grid is numbered and the grid ID is recorded.

[0076] For example, in a DSS scenario, the initial grid model may include a signal strength dimension and a signal-to-interference ratio dimension. For example, the signal strength dimension may be divided into K categories. For each category of signal strength dimension, the signal-to-interference ratio dimension may be divided into M intervals, and the neighboring cell load dimension may be divided into N intervals. The value of N can be set based on actual conditions, and the specific value is not limited here.

[0077] In some embodiments, when K=3, M=5, and N=5, a non-equal interval division method can be adopted to divide the signal strength dimension into 3 intervals: RSRP(-inf,-110], RSRP(-110,-90], RSRP(-90,inf), the signal-to-interference ratio dimension is divided into 5 intervals: sir(-inf,3], sir(3,10], sir(10,20], sir(20,30], sir(30,inf), and the neighboring cell load dimension is divided into 5 intervals: paylo ad(-inf,0.1], payload(0.1,0.3], payload(0.3,0.5], payload(0.5,0.7], payload(0.7,inf). Then, the grids in the initial grid model are divided into two categories: grids corresponding to the RE-level rate matching method and grids corresponding to the symbol-level rate matching method. Based on the signal strength dimension, signal-to-interference ratio dimension, and neighboring cell load dimension, a three-dimensional grid of K×M×N is generated in each category. Each grid is numbered and the grid ID is recorded.

[0078] Step S202: Train the initial grid model based on the first sample signal data of the user terminal in the RE level rate matching mode to obtain first performance information corresponding to each grid in the initial grid model.

[0079] Please refer to Figure 8, which is a schematic diagram of a training grid model provided in an embodiment of the present application. As shown in Figure 8, in the NR+LTE co-frequency scenario, the initial grid model can be trained based on the first sample signal data of the user terminal under the RE-level rate matching method to obtain the first performance information corresponding to each grid in the initial grid model. The initial grid model is trained based on the second sample signal data of the user terminal under the symbol-level rate matching method to obtain the second performance information corresponding to each grid in the initial grid model. Then, the initial grid model is rate matched based on the first performance information and the second performance information of each grid to obtain a preset grid model. Among them, rate matching refers to determining the target rate matching method corresponding to each grid.

[0080] The following uses the NR+LTE co-frequency scenario as an example to illustrate how to train the grid model.

[0081] For example, after constructing the initial grid model, first performance information corresponding to each grid in the initial grid model under the RE-level rate matching method and second performance information corresponding to the symbol-level rate matching method can be determined. The following details how to determine the first performance information corresponding to the grid.

[0082] It should be noted that the first sample signal data may be historical network data, and the first sample signal data may include multiple sample signal parameters of the user terminal under the RE-level rate matching mode and performance information of the user terminal under multiple sample signal parameters. The second sample signal data may include multiple sample signal parameters of the user terminal under the symbol-level rate matching mode and performance information of the user terminal under multiple sample signal parameters. Among them, the sample signal parameters may include the reference signal received power of the serving cell, at least one set of parameter signal received power of the neighboring cells of the serving cell, and at least one set of neighboring cell load information of the neighboring cells. The performance information may include prb (Physical Resource Block) throughput and / or traffic rate, and the performance information is used to measure the use effect of the sample signal parameters under the RE-level rate matching mode and the symbol-level rate matching mode.

[0083] It can be understood that in the NR+LTE co-frequency scenario, since there is no need to use the neighboring cell load information to determine the rate matching method corresponding to the grid, the sample signal parameters may not include at least one set of neighboring cell load information of the neighboring cells of the serving cell.

[0084] For example, the reference signal received power of the serving cell can be expressed as (RSRP0, PCI0). At least one set of parameter signal received power of the neighboring cell can be expressed as {(RSRP1, PCI1), (RSRP2, PCI2), ..., (RSRP m ,PCIm )}. PCI refers to the physical-layer cell identity, which is used to identify different cells. For example, PCI0 refers to the serving cell, PCI1 refers to the first neighboring cell, PCI2 refers to the second neighboring cell, and so on.

[0085] In some embodiments, the initial grid model is trained based on the first sample signal data of the user terminal under the RE-level rate matching mode to obtain the first performance information corresponding to each grid in the initial grid model, which may include: determining the grid to which each sample signal parameter belongs based on the dimensional interval range corresponding to each sample signal parameter; and determining the first performance information of each corresponding grid based on the performance information of the user terminal under all sample signal parameters in each grid.

[0086] Please refer to FIG. 9 , which is a schematic flowchart of sub-steps of determining the grid to which the sample signal parameters belong according to an embodiment of the present application, and may include the following steps S301 to S305 .

[0087] Step S301: sequentially determine each sample signal parameter as the current sample signal parameter.

[0088] Exemplarily, each sample signal parameter in the first sample signal data may be determined as the current sample signal parameter.

[0089] Step S302: Determine a first dimension interval of the current sample signal parameter in the signal strength dimension according to the reference signal received power of the serving cell in the current sample signal parameter.

[0090] Exemplarily, for the current sample signal parameter, a first dimension interval of the current sample signal parameter in the signal strength dimension may be determined based on the reference signal received power of the serving cell in the current sample signal parameter. For example, the first dimension interval may be determined based on the power interval to which the reference signal received power belongs.

[0091] Step S303: Perform signal-to-interference ratio mapping on at least one group of parameter signal received power in the current sample signal parameters to obtain a target signal-to-interference ratio.

[0092] It should be noted that the signal-to-interference ratio (SIR) is defined as the ratio of the interference signal strength to the target echo signal strength. Signal-to-interference ratio mapping converts the parameter signal received power into the signal-to-interference ratio. In the embodiments of the present application, by performing signal-to-interference ratio mapping on the parameter signal received power, the interference strength can be incorporated into the determination of the rate matching method, achieving more refined control of the rate matching method and improving the anti-interference effect of the rate matching.

[0093] The following will describe in detail how to perform signal-to-interference ratio mapping.

[0094] In some embodiments, performing signal-to-interference ratio mapping on at least one set of parameter signal receiving powers in the current sample signal parameters to obtain a target signal-to-interference ratio may include: classifying the at least one set of parameter signal receiving powers into interference neighboring cells to obtain multiple types of interference neighboring cells; calculating based on the parameter signal receiving power set corresponding to each type of interference neighboring cell and the reference signal receiving power of the serving cell to obtain the signal-to-interference ratio corresponding to each type of interference neighboring cell; and determining the target signal-to-interference ratio based on the signal-to-interference ratio corresponding to each type of interference neighboring cell.

[0095] In the embodiment of the present application, the interfering neighboring cells can be classified into the following categories according to the neighboring cell ID modulo 3:

[0096] Index set of type 0 interference neighbor cells: index0 = {i|PCI i mod3 = 0};

[0097] Type 1 interference neighbor cell index set: index1 = {i|PCI i mod3 = 1};

[0098] The second type of interference neighbor cell index set: index2 = {i|PCI i mod3=2}.

[0099] Where i represents a neighboring cell. After classifying the interfering neighboring cells, the PCI mod 3 status of the serving cell where the user terminal is located is determined. Without loss of generality, it is assumed that PCI mod 3 = 0 and only type 1 and type 2 interference are considered. Based on the parameter signal received power set corresponding to each type of interfering neighboring cell and the reference signal received power of the serving cell, the signal-to-interference ratio corresponding to each type of interfering neighboring cell is calculated as follows:

[0100] Where L(·) represents the linear transformation. Indicates the parameter signal receiving power set corresponding to the first type of interference neighboring cell, =(RSRP0) / (RSRP1) represents the reference signal received power set corresponding to the Type 2 interfering neighboring cell, k represents the reference signal received power of the kth neighboring cell, L(RSRP0) represents the reference signal received power of the serving cell, SIR1 represents the signal-to-interference ratio corresponding to the Type 1 interfering neighboring cell, and SIR2 represents the signal-to-interference ratio corresponding to the Type 2 interfering neighboring cell.

[0101] The above formula can be simplified to obtain the following formula:

[0102] Where, Indicates the cell with the largest RSRP among the first type interference neighboring cells. Indicates the cell with the largest RSRP among the Type 2 interference neighboring cells.

[0103] For example, the target signal-to-interference ratio (SIR) can be determined based on the SIR corresponding to each type of interfering neighboring cell. In this embodiment of the present application, the minimum SIR corresponding to all types of interfering neighboring cells can be determined as the target SIR. The target SIR can be expressed as SIR=min(SIR1, SIR2).

[0104] In the above embodiment, the signal-to-interference ratio corresponding to each type of interfering neighboring cell is obtained by calculating based on the parameter signal receiving power set corresponding to each type of interfering neighboring cell and the reference signal receiving power of the serving cell, and the target signal-to-interference ratio is determined based on the signal-to-interference ratio corresponding to each type of interfering neighboring cell. This can convert the parameter signal receiving power of the neighboring cell into a signal-to-interference ratio, and can integrate the interference intensity when determining the rate matching method, thereby achieving more refined control of the rate matching method and improving the anti-interference effect of the rate matching.

[0105] Step S304: Determine a second dimension interval of the current sample signal parameter in the signal-to-interference ratio dimension according to the target signal-to-interference ratio.

[0106] Exemplarily, the second dimension interval may be determined according to the signal-to-interference ratio interval to which the target signal-to-interference ratio belongs.

[0107] Step S305 : Grid positioning is performed according to the first dimension interval and the second dimension interval to obtain the grid to which the current sample signal parameter belongs, until the grid to which each sample signal parameter belongs is determined.

[0108] For example, after determining the first dimensional interval of the current sample signal parameter in the signal strength dimension and the second dimensional interval in the signal-to-interference ratio dimension, grid positioning can be performed according to the first dimensional interval and the second dimensional interval to obtain the grid to which the current sample signal parameter belongs, until the grid to which each sample signal parameter belongs is determined.

[0109] In the above embodiment, by determining the first dimensional interval of the current sample signal parameter in the signal strength dimension and determining the second dimensional interval of the current sample signal parameter in the signal-to-interference ratio dimension according to the target signal-to-interference ratio, it is possible to integrate signal parameters such as signal strength and interference intensity when determining the rate matching method, thereby solving the problem of poor anti-interference effect of the rate matching strategy in the related technology, and being able to more finely control the rate matching method, thereby improving the anti-interference effect of the rate matching.

[0110] Exemplarily, after determining the grid to which each sample signal parameter belongs, the first performance information corresponding to each grid may be determined according to the performance information of the user terminal under all sample signal parameters in each grid.

[0111] The first performance information may include a first performance value, such as a PRB throughput or a traffic rate. The performance values ​​corresponding to the sample signal parameters in each grid may be accumulated to obtain the first performance value of each grid.

[0112] Step S203: The initial grid model is trained according to the second sample signal data of the user terminal in the symbol-level rate matching mode to obtain second performance information corresponding to each grid in the initial grid model.

[0113] In an embodiment of the present application, as shown in FIG8 , after the initial grid model is trained based on the first sample signal data of the user terminal in the RE-level rate matching mode to obtain first performance information corresponding to each grid in the initial grid model, the initial grid model may also be trained based on the second sample signal data of the user terminal in the symbol-level rate matching mode to obtain second performance information corresponding to each grid in the initial grid model. The process of training the initial grid model based on the second sample signal data is the same as the process of training the initial grid model based on the first sample signal data in the above-mentioned embodiment, and is not further described here.

[0114] Step S204: rate matching is performed on the initial grid model according to the first performance information and the second performance information of each grid to obtain a preset grid model.

[0115] Exemplarily, the first performance information includes a first performance value, and the second performance information includes a second performance value. When rate matching is performed on the initial grid model based on the first performance information and the second performance information of each grid, if the first performance value of the grid is greater than the second performance value, the rate matching method associated with the corresponding grid is determined to be the RE-level rate matching method; if the first performance value of the grid is less than the second performance value, the rate matching method associated with the corresponding grid is determined to be the symbol-level rate matching method.

[0116] When the first performance value is equal to the second performance value, the RE-level rate matching mode or the symbol-level rate matching mode may be determined as the grid-associated rate matching mode.

[0117] It should be noted that by performing rate matching on the initial grid model according to the first performance information and the second performance information of each grid, a rate matching method with a higher performance value can be used as the target rate matching method corresponding to the grid.

[0118] The above embodiment, through grid model training and rate matching based on historical network data, is more suitable for the current actual wireless environment than traditional static rate matching and dynamic rate matching schemes, and is more beneficial for interference countermeasures in NR+LTE co-frequency scenarios, and can effectively improve the use effect in interference scenarios.

[0119] Please refer to Figure 10, which is a schematic diagram of another training grid model provided in an embodiment of the present application. As shown in Figure 10, in a DSS scenario, the initial grid model can be trained based on the first sample signal data of the user terminal in the RE-level rate matching mode to obtain first performance information corresponding to each grid in the initial grid model. The initial grid model is trained based on the second sample signal data of the user terminal in the symbol-level rate matching mode to obtain second performance information corresponding to each grid in the initial grid model. Then, the initial grid model is rate matched based on the first performance information and the second performance information of each grid to obtain a preset grid model.

[0120] The following will take the DSS scenario as an example to illustrate how to train the grid model.

[0121] In some embodiments, the initial grid model is trained based on the first sample signal data of the user terminal under the RE-level rate matching mode to obtain the first performance information corresponding to each grid in the initial grid model, which may include: determining the grid to which each sample signal parameter belongs based on the dimensional interval range corresponding to each sample signal parameter; and determining the first performance information of each corresponding grid based on the performance information of the user terminal under all sample signal parameters in each grid.

[0122] Please refer to FIG. 11 , which is a schematic flowchart of another sub-step of determining the grid to which the sample signal parameter belongs provided by an embodiment of the present application, and may include the following steps S401 to S407 .

[0123] Step S401: sequentially determine each sample signal parameter as the current sample signal parameter.

[0124] Step S402: Determine a first dimension interval of the current sample signal parameter in the signal strength dimension according to the reference signal received power of the serving cell in the current sample signal parameter.

[0125] Step S403: Perform signal-to-interference ratio mapping on at least one group of parameter signal received power in the current sample signal parameters to obtain a target signal-to-interference ratio.

[0126] Step S404: Determine a second dimension interval of the current sample signal parameter in the signal-to-interference ratio dimension according to the target signal-to-interference ratio.

[0127] It can be understood that steps S401 to S404 are the same as steps S301 to S304 described above, and are not described in detail here.

[0128] Step S405: Perform load calculation on at least one set of neighboring cell load information in the current sample signal parameters to obtain a target load.

[0129] Exemplarily, neighboring cell load information may include physical resource block (PRB) utilization; PRB is a resource directly used for transmission and sending of user data. PRB resource utilization is an important indicator for evaluating network load and is widely used in wireless network planning and optimization.

[0130] In some embodiments, load calculation is performed on at least one set of neighboring cell load information in the current sample signal parameters to obtain a target load, which may include: determining a target neighboring cell participating in the load calculation; and determining the target load based on the physical resource block utilization and the starting position of the physical resource block of the target neighboring cell.

[0131] It should be noted that the target neighboring cell refers to the interfering neighboring cell that participates in the load calculation. In the embodiment of the present application, since not all interfering neighboring cells generate significant interference, and the interference generated by some interfering neighboring cells can be treated as noise and ignored, it is necessary to first determine whether the interfering neighboring cell participates in the load calculation. The following will provide a detailed explanation of how to determine whether the interfering neighboring cell participates in the load calculation.

[0132] For example, the PRB utilization of the corresponding neighboring cell can be retrieved from the neighboring cell load information in the DSS scenario according to the above-mentioned multiple types of interference neighboring cell index sets. If the PRB utilization is not retrieved, the PRB utilization of the corresponding neighboring cell is set to zero. It should be noted that in the embodiment of the present application, the neighboring cell is the interfering cell.

[0133] Then, calculate the load corresponding to each type of interfering neighboring cell as follows:

[0134] In formula (1), Indicates that the cell with the largest RSRP is found in the neighboring cell with type 0 interference. i_max0 indicates the cell with the largest RSRP in the neighboring cell with type 0 interference. i_max0 Indicates the PRB utilization rate of the cell with the largest RSRP in the 0th type interference neighboring cell, and Lod0 indicates the load of the 0th type interference cell. In formula (2), Indicates that the cell with the largest RSRP is found in the first type of interference neighboring area, and i_max1 indicates the cell with the largest RSRP in the first type of interference neighboring area. i_max1 Indicates the PRB utilization rate of the cell with the largest RSRP in the first type of interference neighboring cell, and Lod1 indicates the load of the first type of interference cell. In formula (3), Indicates that the cell with the largest RSRP is found in the second type of interference neighboring area, and i_max2 indicates the cell with the largest RSRP in the second type of interference neighboring area.i_max2 Indicates the PRB utilization rate of the cell with the largest RSRP among the interference neighbor cells of the second type. Lod2 represents the load of the interference cells of the second type.

[0135] After determining the load corresponding to each type of interference neighbor cell, the target neighbor cells participating in the load calculation can be determined. Exemplarily, the target neighbor cells can be determined according to the reference signal received power of the serving cell and the reference signal received power of each neighbor cell. In the embodiments of the present application, the target neighbor cells participating in the load calculation can be determined according to the formula RSRP0 - RSRP i_maxk <SIR + Th

[0136] In the formula, RSRP i_maxk represents the cell with the largest RSRP among the interference cells of the k-th type; SIR represents the target signal-to-interference ratio; Th is the offset value, which defaults to 3 dB, and of course can also be other values.

[0137] Exemplarily, if RSRP0 = -80, RSRP i_max0 = -83, RSRP i_max1 = -85, RSRP i_max2 = -100, SIR = 3 dB, then since RSRP0 - RSRP i_max0 = 3 < 3 + 3, the load of the interference neighbor cells of the 0th type is included in the load calculation; since RSRP0 - RSRP i_max1 = 5 < 3 + 3, the load of the interference neighbor cells of the 1st type is included in the load calculation; since RSRP0 - RSRP i_max2 = 20 > 3 + 3, the load of the interference neighbor cells of the 2nd type is not included in the load calculation. That is, the cells in the interference neighbor cells of the 0th type and the cells in the interference neighbor cells of the 1st type can be used as the target neighbor cells.

[0138] Exemplarily, if RSRP0 = -80, RSRP i_max0 = -105, RSRP i_max1 = -110, RSRP i_max2 = -107, SIR = 25 dB, then since RSRP0 - RSRP i_max0 = 25 < 28, the load of the interference neighbor cells of the 0th type is included in the load calculation; since RSRP0 - RSRP i_max1 = 30 > 25 + 3, the load of the interference neighbor cells of the 1st type is not included in the load calculation; since RSRP0 - RSRP i_max2 = 27 < 25 + 3, the load of the interference neighbor cells of the 2nd type is included in the load calculation. That is, the cells in the interference neighbor cells of the 0th type and the cells in the interference neighbor cells of the 2nd type are used as the target neighbor cells.

[0139] By determining the target neighboring areas involved in load calculation, the neighboring areas that produce less interference can be eliminated to avoid interference with subsequent target load calculations and improve accuracy.

[0140] For example, for each type of neighboring cell participating in the neighboring cell load calculation, when determining the target load based on the physical resource block utilization rate and the starting position of the physical resource block of the target neighboring cell, the interval occupied by each type of neighboring cell in the physical resource block can be calculated separately, and the union of all occupied intervals can be calculated, and the obtained union interval can be used as the target load.

[0141] For example, for the type 0 interference neighboring cell and the type 1 interference neighboring cell, if the starting position of the physical resource block of the type 0 interference neighboring cell is 0 and the physical resource block utilization rate is 20%, and the starting position of the physical resource block of the type 1 interference neighboring cell is 1 / 3 and the physical resource block utilization rate is 70%, then the interval occupied by the physical resource blocks of the type 0 interference neighboring cell is [0,0.2], and the intervals occupied by the physical resource blocks of the type 1 interference neighboring cell are [1 / 3,1] and [0,1 / 30], the union intervals are [0,0.2] and [1 / 3,1], and the target load is 13 / 15.

[0142] The target load can be determined by performing interval union based on the physical resource block utilization and the starting position of the physical resource block of the target neighboring cell.

[0143] Step S406: Determine the third dimension interval of the current sample signal parameter on the neighboring cell load dimension according to the target load.

[0144] Exemplarily, after load calculation is performed on at least one set of neighboring cell load information in the current sample signal parameter to obtain a target load, a third-dimensional interval of the current sample signal parameter in the neighboring cell load dimension can be determined based on the target load. For example, the third-dimensional interval of the previous sample signal parameter in the neighboring cell load dimension can be determined based on the load interval to which the target load belongs.

[0145] Step S407: performing grid positioning according to the first dimension interval, the second dimension interval, and the third dimension interval to obtain the grid to which the current sample signal parameter belongs.

[0146] For example, after determining the first dimensional interval of the current sample signal parameter in the signal strength dimension, the second dimensional interval in the signal-to-interference ratio dimension, and the third dimensional interval in the neighboring cell load dimension, grid positioning can be performed according to the first dimensional interval, the second dimensional interval, and the third dimensional interval to obtain the grid to which the current sample signal parameter belongs, until the grid to which each sample signal parameter belongs is determined.

[0147] Exemplarily, after determining the grid to which each sample signal parameter belongs, the first performance information corresponding to each grid may be determined according to the performance information of the user terminal under all sample signal parameters in each grid.

[0148] In an embodiment of the present application, in a DSS scenario, after the initial grid model is trained based on the first sample signal data of the user terminal in the RE-level rate matching mode to obtain the first performance information corresponding to each grid in the initial grid model, the initial grid model may also be trained based on the second sample signal data of the user terminal in the symbol-level rate matching mode to obtain the second performance information corresponding to each grid in the initial grid model. The process of training the initial grid model based on the second sample signal data is the same as the process of training the initial grid model based on the first sample signal data in the above-mentioned embodiment, and is not further described here.

[0149] In the above embodiment, by performing grid positioning according to the first dimensional interval, the second dimensional interval and the third dimensional interval, the grid to which the current sample signal parameter belongs is obtained, and it is possible to integrate signal parameters such as signal strength and interference intensity when determining the rate matching method, thereby solving the problem of poor anti-interference effect of the rate matching strategy in the related technology, and being able to control the rate matching method more finely, thereby improving the anti-interference effect of the rate matching.

[0150] Exemplarily, after obtaining the first performance information and second performance information corresponding to each grid in the initial grid model, rate matching can be performed on the initial grid model based on the first performance information and second performance information of each grid to obtain a preset grid model. For example, if the first performance value of the grid is greater than the second performance value, the rate matching method associated with the corresponding grid is determined to be the RE-level rate matching method; if the first performance value of the grid is less than the second performance value, the rate matching method associated with the corresponding grid is determined to be the symbol-level rate matching method.

[0151] It should be noted that by performing rate matching on the initial grid model according to the first performance information and the second performance information of each grid, a rate matching method with a higher performance value can be used as the target rate matching method corresponding to the grid.

[0152] The above embodiment, by performing grid model training and rate matching based on historical network data, is more suitable for the current actual wireless environment than traditional static rate matching and dynamic rate matching schemes, is more beneficial for interference countermeasures in DSS scenarios, and can effectively improve the use effect in interference scenarios.

[0153] Please refer to FIG. 12 , which is a schematic flowchart of sub-steps for determining a target grid provided in an embodiment of the present application. Step S102 may include the following steps S501 to S503 .

[0154] Step S501: Determine a first dimension interval corresponding to a target grid according to the power interval to which the first reference signal received power belongs.

[0155] For example, as shown in FIG5 , in the NR+LTE co-frequency scenario, the first dimension interval corresponding to the target grid can be determined according to the power interval to which the first reference signal received power belongs. For example, the first dimension interval is RSRP(-110,-90].

[0156] Step S502: Determine a second dimension interval corresponding to the target grid according to the power interval to which the second reference signal received power belongs.

[0157] As shown in Figure 5, in the NR+LTE co-frequency scenario, the second dimension interval corresponding to the target grid can be determined based on the power interval to which the second reference signal received power belongs. For example, the second reference signal received power can be mapped to the signal-to-interference ratio to obtain the target signal-to-interference ratio, and then the second dimension interval can be determined based on the signal-to-interference ratio interval of the target signal-to-interference ratio in the signal-to-interference ratio dimension. For example, the second dimension interval is sir(3,10].

[0158] Step S503: performing grid positioning in the grid model according to the first dimension interval and the second dimension interval to obtain a target grid.

[0159] For example, after determining the first dimension interval and the second dimension interval corresponding to the target grid, grid positioning can be performed in the grid model based on the first dimension interval and the second dimension interval to obtain the target grid. For example, if the first dimension interval is RSRP(-110,-90] and the second dimension interval is sir(3,10], then the grid corresponding to RSRP(-110,-90] and sir(3,10] in the grid model can be determined as the target grid.

[0160] The above embodiment obtains the target grid by performing grid positioning in the grid model according to the first dimensional interval and the second dimensional interval, and can integrate signal parameters such as signal strength and interference strength when determining the rate matching method, thereby solving the problem of poor anti-interference effect of the rate matching strategy in the related technology, and can control the rate matching method more finely, thereby improving the anti-interference effect of the rate matching.

[0161] Please refer to FIG. 13 , which is a schematic flowchart of another sub-step of determining a target grid provided in an embodiment of the present application. Step S102 may further include the following steps S601 to S604 .

[0162] Step S601: Determine a first dimension interval corresponding to a target grid according to the power interval to which the first reference signal received power belongs.

[0163] 6 , in a DSS scenario, the first dimension interval corresponding to the target grid can be determined based on the power interval to which the first reference signal received power belongs. For example, the first dimension interval is RSRP(-inf,-110].

[0164] Step S602: Determine a second dimension interval corresponding to the target grid according to the power interval to which the second reference signal received power belongs.

[0165] As shown in Figure 6, in a DSS scenario, the second dimension interval corresponding to the target grid can be determined based on the power interval to which the second reference signal received power belongs. For example, the second reference signal received power can be mapped to the signal-to-interference ratio to obtain the target signal-to-interference ratio, and then the second dimension interval can be determined based on the signal-to-interference ratio interval of the target signal-to-interference ratio in the signal-to-interference ratio dimension. For example, the second dimension interval is sir(10,20].

[0166] Step S603: Determine the third dimension interval corresponding to the target grid according to the load interval to which the neighboring cell load information belongs.

[0167] As shown in Figure 6, in a DSS scenario, the third dimension interval corresponding to the target grid can be determined based on the load interval to which the neighboring cell load information belongs. For example, the second reference signal received power can be used for load calculation to obtain the target load, and then the third dimension interval is determined based on the load interval of the target load in the neighboring cell load dimension. For example, the third dimension interval is payload(0.1,0.3].

[0168] Step S604: locating the grid in the grid model according to the first dimension interval, the second dimension interval, and the third dimension interval, and determining the located grid as the target grid.

[0169] Exemplarily, after determining the first dimension interval, the second dimension interval, and the third dimension interval corresponding to the target grid, grid positioning can be performed in the grid model according to the first dimension interval, the second dimension interval, and the third dimension interval to obtain the target grid. For example, if the first dimension interval is RSRP(-inf,-110], the second dimension interval is sir(10,20], and the third dimension interval is payload(0.1,0.3], then the grid corresponding to RSRP(-inf,-110], sir(10,20], and payload(0.1,0.3] in the grid model can be determined as the target grid.

[0170] The above embodiment, by performing grid positioning in the grid model according to the first dimensional interval, the second dimensional interval and the third dimensional interval, can realize the fusion of signal parameters such as signal strength and interference intensity when determining the rate matching method, thereby solving the problem of poor anti-interference effect of the rate matching strategy in the related technology, and can control the rate matching method more finely, thereby improving the anti-interference effect of the rate matching.
