The performance goals of 5G are high data rates, reduced latency, energy savings, cost reduction, increased system capacity and large-scale device connections. Compared with the 4G system, the 5G system introduces the beam pairing method.

Because the 5G system is compatible with low-frequency and higher-frequency millimeter waves, considering the propagation loss of millimeter waves, a narrow beam method is adopted to improve signal coverage, and a multi-beam method is used to cover the cell. The measurements based on the traffic channel are all based on the multi-beam of the Channel State Information Reference Signal (CSI-RS) reference signal, and the base station selects the optimal beam for downlink transmission according to the information reported by the terminal.

detailed description

Hereinafter, embodiments of the present application will be described with reference to the drawings. In the case of no conflict, the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily.

Fig. 1 is a schematic diagram of an application scenario of a beam configuration method provided by an embodiment. As shown in Figure 1, in a 5G communication system, both the terminal and the base station corresponding to the cell can support multiple beams. Illustratively, the base station in Figure 1 supports 7 beams, and the terminal supports 3 beams. The base station and the terminal rely on uplink and downlink beam pairs for communication. In order to enable the multiple beams of the cell to effectively cover the location of the user in the cell and allow the user to obtain the best signal, it is necessary to configure the beam of the cell, that is, to determine the direction of the beam of the cell and other information. The method of beam configuration for the cell based on the network optimization experience cannot achieve the optimal coverage effect, resulting in low overall spectrum efficiency of the cell.

This application provides a beam configuration method, which selects N _b initial beams to cover the N _b first grids of the cell for each beam configuration period within a preset time period, and calculates the beam proportion of each initial beam, according to The beam ratio of the initial beam is determined, the beam configuration information of the cell is determined, and the beam configuration information is automatically selected. Compared with the configuration based on network optimization experience, the overall spectrum efficiency of the cell is improved, and the user rate and users of the cell are effectively improved Perception.

FIG. 2 is a schematic flowchart of a beam configuration method provided by an embodiment. This embodiment is applicable to a scenario where the base station sets the beam of the cell it manages. This embodiment can be executed by a beam configuration device, which can be implemented by software and/or hardware, and the beam configuration device can be integrated in a base station. As shown in FIG. 2, the beam configuration method provided in this embodiment includes the following steps:

Step 201: In each beam configuration period, select N _b initial beam configuration information corresponding to the first index from the beam configuration table of the cell to cover the N _b first grids of the cell, and count each initial beam The beam accounted for.

In an embodiment, the beam ratio is the ratio of the number of times that each initial beam is scheduled to the total number of times that the initial beam is scheduled in each beam configuration period, and N _b is the beam supported by the base station corresponding to the cell Number. N _b is an integer greater than or equal to 1.

Step 202: Use the next index in the beam configuration table as the new first index, and use the other N _b grids of the cell as the new first grid. In the next beam configuration cycle, return to the execution step 201, until the beam proportion of the initial beam corresponding to each grid in the preset time period is determined.

In one embodiment, for the cell coverage area planned according to the network plan, this embodiment divides the coverage area into grids according to the horizontal width and vertical width of the coverage area to obtain N _grid grids. FIG. 3A is a schematic diagram of a grid of cell division in a beam configuration method provided by an embodiment. As shown in Fig. 3A, suppose the base station corresponding to the cell radiates inward from the plane of Fig. 3A, intercept one of the coverage planes, and divide it into N _grid grids according to the horizontal width and the vertical width. This N _grid raster size may all be the same or not the same, may be the same portion, part not identical, the present embodiment is not limited to this embodiment. Exemplarily, the cell coverage area is divided into 10*10 grids of the same size in FIG. 3A.

In this embodiment, the number of beams supported by the base station corresponding to the cell is N _b . In order to determine _{the configuration information of the N b} beams, that is, where the N _b beams can achieve the optimal coverage effect and improve the overall spectrum efficiency of the cell, this embodiment adopts the initial beam traversal grid method to determine each The beam proportions of the initial beams, and further, the beam configuration information of the cell is determined.

The initial beam in this embodiment refers to the beam corresponding to the configuration information in the beam configuration table of the cell. The beam configuration table includes multiple indexes, and each index corresponds to N _b initial beams.

Since the base station supports N _b beams, when traversing the grid, each beam configuration period can cover N _b grids at a time. Optionally, the minimum granularity of the beam configuration period is days.

Optionally, based on the number of grids and the number of beams supported by the base station, the total number of indexes in the beam configuration table can be calculated

That is, it takes S times to cover all the grids once. Among them, this formula means that N _grid is divided by N _{b and} then rounded up. Table 1 is the beam configuration table of the cell.

Table 1 Beam configuration table of the cell

Among them, the configuration information of the j-th initial beam corresponding to the i-th index in the beam configuration table includes: [hw _ij , ha _ij , vw _ij , va _ij ], hw _ij represents the i-th index corresponding to the i-th index in the beam configuration table The horizontal beam width of j initial beams, ha _ij represents the horizontal beam angle of the j-th initial beam corresponding to the i-th index in the beam configuration table _{, and vw ij represents the j-th initial beam corresponding to the i-th index in the beam configuration table} The vertical beam width of, va _ij represents the vertical beam angle of the j-th initial beam corresponding to the i-th index in the beam configuration table. The configuration information of the initial beam is preset information. The beam configuration information may also include other information related to the beam configuration, and this embodiment is not limited thereto.

In the beam configuration table, each configuration information corresponds to an initial beam. The beam configuration table includes a total of N _grid initial beams, that is, each grid corresponds to one initial beam.

In each beam configuration period, the configuration information _{of the N b} initial beams corresponding to the first index is used to _{cover the N b} grids of the cell, that is, the N _b initial beams _{corresponding to the first index are used to cover N b of the} cells. Grid, count the beam ratio of each initial beam. In the next beam configuration period, another N _b initial beams are used to cover another N _b grids, and the beam proportion of each initial beam is counted until the beam proportion of the initial beam corresponding to each grid is determined. The beam ratio in this embodiment refers to the ratio of the number of times that each initial beam is scheduled to the total number of times that the initial beam is scheduled in each beam configuration period. For example, assuming that N _b is equal to 4, in a beam configuration cycle, the initial beam 1 corresponding to an index is scheduled 10 times, the initial beam 2 is scheduled 20 times, the initial beam 3 is scheduled 10 times, and the rest of the initial beam The beam is not scheduled, so the beam accounted for the initial beam 1 is 25%.

In an embodiment, when the configuration information _{of the N b} initial beams corresponding to the first index is used to _{cover the N b} grids of the cell, the N _b initial beams _{may be used to cover N b} adjacent or continuous grids, It may also cover N _b non-adjacent or continuous grids, which is not limited in this embodiment. This embodiment _{also does not limit the correspondence between N b} initial beams and N _b grids. For example, assuming that N _b is equal to 4, the positions of the 4 grids are shown in FIG. 3A, which may be that the initial beam 1 covers the upper left. The corner grid 1, the initial beam 2 covers the grid 2 in the upper right corner, the initial beam 3 covers the grid 3 in the lower left corner, the initial beam 4 covers the grid 4 in the lower right corner, or the initial beam 1 covers the grid 2. Initial beam 2 covers grid 3, initial beam 3 covers grid 4, and initial beam 4 covers grid 1. When the index is numbered from 0, the initial first index is also 0, and the initial first index can also be any index in the beam configuration table, as long as the initial beam in the beam configuration table is used to align each grid Just cover it.

Optionally, the preset time period in this embodiment may be a defined time period, or may be the product of the beam configuration period and the total number of indexes in the beam configuration table. When the preset time period is the product of the beam configuration period and the total number of indexes in the beam configuration table, it is realized that each grid is covered by the initial beam exactly once within the preset time period, which can improve the beam configuration effectiveness.

Step 203: Determine the beam configuration information of the cell according to the beam proportion of the initial beam corresponding to each grid in the preset time period.

In an embodiment, after determining the beam proportions of the initial beams corresponding to each grid within a preset time period, the beam configuration information of the cell is determined according to these beam proportions, and the following two implementation manners can be implemented.

FIG. 4A is a schematic flowchart of an implementation manner of step 203 in a beam configuration method provided by an embodiment. In the first implementation manner, as shown in FIG. 4A, step 203 includes the following steps.

Step 2031: Sort the multiple beam ratios in descending order.

Step 2032: Use the initial beam corresponding to the _{first N b beam ratios as the target beam.}

Step 2033: Determine the configuration information corresponding to the target beam in the beam configuration table as the beam configuration information of the cell.

_{In this implementation manner, the configuration information of the initial beams of the N b} beams with the largest beam ratio is selected as the beam configuration information of the cell. FIG. 3B is a schematic diagram _{of N b} target beams determined in a beam configuration method provided by an embodiment. For example, as shown in Figure 3B, assuming that N _b is 4 and N _grid is 16, the grid positions corresponding to the four target beams with the largest beam proportions are finally determined as grid 1, grid 6, and grid 13 and grid 16. Among them, the configuration information of the target beam corresponding to grid 1 is the configuration information of the first initial beam of the 0th index in the beam configuration table [hw ₀₁ , ha ₀₁ , vw ₀₁ , va ₀₁ ], and the target corresponding to grid 6 The configuration information of the beam is the configuration information of the 4th initial beam of the 0th index in the beam configuration table [hw ₀₄ , ha ₀₄ , vw ₀₄ , va ₀₄ ], and the configuration information of the target beam corresponding to grid 13 is the beam configuration table The configuration information of the first initial beam [hw ₃₁ , ha ₃₁ , vw ₃₁ , va ₃₁ ] in the 3rd index in the grid, the configuration information of the target beam corresponding to grid 16 is the 4th in the 3rd index in the beam configuration table Configuration information of the initial beams [hw ₃₄ , ha ₃₄ , vw ₃₄ , va ₃₄ ]. Then the configuration information [hw ₀₁ ,ha ₀₁ ,vw ₀₁ ,va ₀₁ ], configuration information [hw ₀₄ ,ha ₀₄ ,vw ₀₄ ,va ₀₄ ], configuration information [hw ₃₁ ,ha ₃₁ ,vw ₃₁ ,va ₃₁ ] and The configuration information [hw ₃₄ , ha ₃₄ , vw ₃₄ , va ₃₄ ] is determined as the beam configuration information of the cell.

FIG. 4B is a schematic flowchart of another implementation manner of step 203 in a beam configuration method provided by an embodiment. In the second implementation manner, as shown in FIG. 4B, step 203 includes the following steps.

Step 2034: Accumulate the beam proportions in descending order, and stop the accumulation when it is determined that the accumulated sum is greater than or equal to the preset coverage threshold.

Step 2035: Use the set of initial beams corresponding to the beam proportions participating in the accumulation as the optimal subspace of the cell beam coverage.

Step 2036: Determine the beam configuration information of the cell according to the optimal subspace.

In an embodiment, the implementation process of step 2036 may be as follows: if the number of initial beams in the optimal subspace is less than N _b , the corresponding beams in the initial beams other than the initial beams in the optimal subspace The first number of initial beams with the largest proportion is added to the optimal subspace to form the corrected optimal subspace; in the beam configuration table, the configuration information corresponding to the initial beam in the corrected optimal subspace is determined as The beam configuration information of the cell. Among them, the first number is N _b -N _s , and N _s is the number of initial beams in the optimal subspace.

In another embodiment, the implementation process of step 2036 may be: if the number of initial beams in the optimal subspace is greater than N _b , according to the beam combining principle, the initial beams in the optimal subspace are combined into N _b beams , Forming the modified optimal subspace; according to the configuration information corresponding to the initial beams participating in the merging in the beam configuration table, determine the configuration information of the combined beam in the modified optimal subspace; modify the beam configuration table The configuration information corresponding to the initial beam in the subsequent optimal subspace and the configuration information of the combined beam are determined as the beam configuration information of the cell.

Optionally, the beam combining principle includes: combining the initial beams corresponding to adjacent grids according to the positions of the grids corresponding to the initial beams; the beam proportions corresponding to the combined beams cannot be greater than a preset threshold, and the threshold is

among them,

Indicates that the quotient of 100 and (N _b +1) is rounded down.

In an embodiment, the implementation process of step 2036 may be: if the number of initial beams in the optimal subspace is equal to N _b , determine the configuration information corresponding to the initial beams in the optimal subspace in the beam configuration table as the cell Beam configuration information.

The following uses an example to illustrate the process of the second implementation of step 203. Assume that N _b is 4.

If the optimal subspace determined in step 2035 includes 2 initial beams, add 4-2 initial beams with the largest beam ratio among other initial beams except the 2 initial beams in the optimal subspace In the optimal subspace, a modified optimal subspace is formed. After that, the configuration information corresponding to the four initial beams in the modified optimal subspace is determined as the beam configuration information of the cell.

If the optimal subspace determined in step 2035 includes 5 initial beams, the 5 initial beams are merged into 4 beams according to the beam merging principle to form the modified optimal subspace. According to the configuration information corresponding to the initial beams participating in the merging in the beam configuration table, determine the configuration information of the combined beams in the modified optimal subspace. For example, the configuration information of the initial beams participating in the merging can be weighted and averaged to determine Is the configuration information of the combined beam. Assuming that the optimal subspace includes the initial beam a, the initial beam b, the initial beam c, the initial beam d, and the initial beam e, according to the beam combination principle, it is determined to combine the initial beam b and the initial beam c to form a combined beam. Exemplarily, the weighted average of the configuration information of the initial beam b and the initial beam c in the beam configuration table may be determined as the beam configuration information after the initial beam b and the initial beam c are combined. The configuration information of the combined beam may also be determined according to other methods, for example, any one of the configuration information of the initial beam b and the initial beam c is determined as the configuration information of the combined beam. In the beam configuration table, the configuration information corresponding to the initial beam a, the configuration information corresponding to the initial beam d, the configuration information corresponding to the initial beam e, and the configuration information of the combined beam of the initial beam b and the initial beam c are determined as the cell’s Beam configuration information.
