the method for determining the signal-to-interference-plus-noise ratio provided by the embodiment of the invention is suitable for the base station and the terminal shown in fig. 1. When a base station sends (transport, TX) information, data is transmitted through k transmission links; when information is transmitted by the kth transmission link, firstly, according to a symbol (symbol) carried in a sub-base band (sub-band) k (where the symbol refers to information that needs to be transmitted by a base station), then, according to a carrier spacing (sub-carrier spacing) k, performing Inverse Fast Fourier Transform (IFFT) on the symbol to obtain a signal k, further adding (add) a cyclic redundancy code (cyclic prefix, CP) k to the signal k, and then, performing signal processing on the signal k added with the CPk by using a beam shaping filter (beam shaping filter), thereby obtaining the signal k after the kth transmission link performs beam shaping. And finally, performing beam integration on the signals k subjected to beam forming by each transmission link, and transmitting the signals subjected to beam integration to a signal receiving end through an antenna, thereby realizing information transmission.

When a terminal receives (receive, RX) a symbol carried on a sub-base-band k transmitted from a base station through an antenna, a signal processing is performed on the symbol through a shaping filter to obtain a processed signal, then a CP of the signal is removed, then a Fast Fourier Transform (FFT) is performed on the signal from which the CP is removed according to a carrier interval k, and then Orthogonal Frequency Division Multiplexing (OFDM) detection is performed on the sub-base-band i of the signal subjected to the FFT signal processing, so that the symbol carried on the sub-base-band k transmitted by the antenna receiving base station is converted into a signal that can be recognized by the terminal. In the embodiment of the present invention, the device for determining the inter-station distance may be a base station or a base station controller in wireless communication, and the like.

With the increasing demand of users for services, the types and edge rates of services are increased or increased in different degrees, and the service demand in the fifth generation mobile communication technology (5 th-generation, 5G) era is taken as an example for description.

According to different edge rate requirements, the following 3 service types can be divided.

The first type of service is mainly some common services, including services such as instant messaging, web browsing, social media, file transfer, remote desktop, online games, high-definition video, and the like. The requirements of services such as instant messaging, web browsing, social media, file transmission, remote desktop, online games, and high definition video on the uplink edge rate and the downlink edge rate are shown in table 1.

Therefore, with the abundance of wireless communication service types and the reduction of charges, the wireless communication demand of users is rapidly increased, and when the network bearing capacity is improved by newly building a base station, the inter-station distance is configured by depending on personal experience, so that the accuracy of the inter-station distance cannot be ensured. Therefore, the embodiment of the invention provides a method for determining the inter-station distance, which introduces details on how to calculate the inter-station distance.

Specifically, as shown in fig. 2, taking the device to be accessed as the base station to be established and the device to be accessed as the established base station as an example, the method may include the following steps S11 to S15:

s11, acquiring the station height and the station track gauge of the access network equipment to be built. And the station track gauge is used for indicating the distance between the access network equipment to be built and the train track.

Specifically, for convenience of calculation, the station track gauge is the shortest distance between the base station to be established and the train track.

And S12, inquiring a predetermined first table according to the station height and the station track gauge, and determining the uplink station spacing of the access network equipment to be built. The first table comprises the corresponding relation among the station height, the station track distance and the uplink station distance.

And S13, inquiring a predetermined second table according to the station height and the station track gauge, and determining the downlink station spacing of the access network equipment to be built. The second table comprises the corresponding relation among the station height, the station track distance and the descending station distance.

And S14, when the uplink station spacing and the downlink station spacing meet the preset conditions, determining the station spacing of the access network equipment to be built as the uplink station spacing.

And S15, when the uplink station spacing and the downlink station spacing do not meet the preset conditions, determining the station spacing of the access network equipment to be built as the downlink station spacing.

Specifically, the preset condition is that the uplink inter-station distance is smaller than or equal to the downlink inter-station distance, and therefore when the uplink inter-station distance is determined to be smaller than or equal to the downlink inter-station distance, the inter-station distance of the access network equipment to be established is determined to be the uplink inter-station distance; and when the uplink station spacing is determined to be larger than the downlink station spacing, determining the station spacing of the access network equipment to be established as the downlink station spacing.

The method for determining the inter-station distance provided by the embodiment of the invention obtains a first table by collecting the corresponding relation among the station height, the track distance of the uplink station and the inter-station distance of the established base station, and obtains a second table by collecting the corresponding relation among the station height, the track distance of the downlink station and the inter-station distance of the established base station. Therefore, the operator only needs to determine the uplink station spacing according to the first table and the station height and the station track distance acquired from the base station to be built, and then determines the downlink station spacing according to the second table and the station height and the station track distance acquired from the base station to be built. And finally, determining the inter-station distance of the base station to be established by judging whether the uplink inter-station distance and the downlink inter-station distance meet a preset relation.

Specifically, referring to fig. 2, as shown in fig. 3, the method for determining the inter-station distance according to the embodiment of the present invention further includes S16 to S18.

S16, acquiring a first configuration parameter of the established access network equipment, a second configuration parameter of at least one target terminal and network data. The network data comprises an uplink edge rate of a packet data convergence protocol PDCP layer and a downlink edge rate of the PDCP layer, the target terminal is located in the coverage range of the established access network equipment, and the moving rate of the target terminal is larger than the preset rate.

Specifically, in order to ensure that the actually obtained first table and second table have higher accuracy, a large amount of network data collected by the target terminal in the coverage area of each base station in at least one established base station under different inter-station distance, inter-station track distance, inter-station height parameters and the like needs to be collected here.

For example, taking the target terminal as a 5G terminal as an example, the process of acquiring the network data acquired by the target terminal in the coverage area of each base station in at least one established base station under different inter-station distance, inter-station track distance, inter-station height parameters is as follows:

the method comprises the steps that a 5G terminal is placed on the passageway side of a high-speed rail, user Datagram Protocol (UDP) uplink service is launched through the 5G terminal and kept, and drive test software records relevant data (a time stamp, a Physical Cell Identifier (PCI), the moving speed of the 5G terminal, the longitude and the latitude of the 5G terminal and the uplink edge speed of a PDCP layer).

Meanwhile, after the UDP uplink service test is completed, the 5G terminal initiates and maintains the UDP downlink service, and the drive test software records the relevant data (a timestamp, a Physical Cell Identifier (PCI), the moving rate of the 5G terminal, the longitude and latitude of the 5G terminal, and the downlink edge rate of the PDCP layer).

If the UDP uplink service initiated by the 5G terminal is disconnected, the 5G terminal needs to reinitiate the UDP uplink service near the test point, and after the speed is stable, the test is continued.

Specifically, in the method for determining the inter-station distance provided by the embodiment of the present invention, users are classified according to the moving rate. Therefore, when the preset speed is 250km/h, the target terminals with the moving speed greater than 250km/h can be screened, so that the network data collected by the target terminals on the high-speed train can be determined.

It should be noted that, when the number of the established base stations is certain and the number of the target terminals in the coverage area of each established base station is larger, the determined first table and the determined second table are more in line with the actual distribution, that is, the operator can accurately determine the inter-station distance of the base station to be established according to the preset formula.

When the number of the target terminals in the coverage area of each established base station is certain and the number of the established base stations is larger, the determined first table and the second table are more consistent with actual distribution, namely, an operator can accurately determine the inter-station distance of the base station to be established according to the first table and the second table.

Specifically, the first position information and the second position information are Global Positioning System (GPS) coordinates.

For example, the second configuration parameter of each target terminal and the corresponding relationship between the uplink edge rate of the PDCP layer of the target terminal, the downlink edge rate of the PDCP layer, and the terminal height in the network data collected by each target terminal are shown in table 4.

TABLE 4

Specifically, the operator may distinguish each established base station by Physical Cell Identity (PCI).

Illustratively, the correspondence relationship among the first location information, the station track gauge, the station spacing, and the station height of each established base station is shown in table 5.

TABLE 5

It should be noted that, the inter-site distance of the base stations deployed in the 5G network is lower than that of the fourth generation mobile communication technology (4G) network. And the currently acquired inter-site distance of the established base station is the inter-site distance of the base station of the 4G network. Therefore, it is necessary to optimize the actually obtained inter-site distance of the base stations of the 4G network, and ensure that after the base stations of the 5G network are deployed according to the optimized inter-site distance, coverage signals between adjacent base stations are continuous.

S17, determining a first table according to the first configuration parameter, the second configuration parameter of each target terminal in the at least one target terminal and the uplink edge rate of the PDCP layer.

S18, determining a second table according to the first configuration parameter, the second configuration parameter of each target terminal in the at least one target terminal and the downlink edge rate of the PDCP layer.

Specifically, when the first configuration parameter includes first position information, station track distance, overlap coverage distance, and station height, and the second configuration parameter includes second position information and terminal height, as shown in fig. 4 in conjunction with fig. 3, the above step S17 may be specifically implemented by S170 to S172 described below.

Specifically, as shown in fig. 5, the station height of the established base station 1 is a, the station track gauge of the established base station 1 is b, the overlapping coverage distance of the established base station 1 is c, and the horizontal coverage distance of the established base station 3 is c. Wherein, a represents the vertical length of the connecting line between the top point of the established base station 1 and the lowest point of the established base station 1, b represents the vertical distance from any point on the established base station 1 to the train track, c represents the total length of the connecting line between the central point of the established base station 1 and the central point of the established base station 2 in the overlapping coverage range of the established base station 1 and the established base station 2, d represents the horizontal coverage distance of the established base station 3, and e represents the coverage area of the established base station 3.

S170, determining the relative station height according to the station height of the established access network equipment and the terminal height of each target terminal in at least one target terminal.

Specifically, when the station height of the established base station and the terminal height of the target terminal are measured, the ground plane is used as a reference plane, so that the relative station height of the established base station relative to the target terminal can be determined. Wherein, the relative station height is equal to the station height of the established base station minus the terminal height of the target terminal.

S171, determining an uplink station spacing according to the first position information, the station track distance and the overlapping coverage distance of the established access network equipment, the second position information of each target terminal in at least one target terminal and the uplink edge rate of the PDCP layer.

Specifically, the determining the uplink inter-station distance according to the first location information, the station track distance, the overlapping coverage distance of the established access network device, the second location information of each target terminal in the at least one target terminal, and the uplink edge rate of the PDCP layer includes:

1. and determining the relative distance according to the first position information of the established base station and the second position information of each target terminal in at least one target terminal. Wherein, the target terminal is located in the coverage area of the established base station, and the relative distance satisfies

Wherein D is _i Indicating the relative distance, LA, of the target terminal i from the established base station _NR Representing established basisLongitude of the station, LO _NR Indicating latitude, LA, of the established base station _UEi Indicating the longitude, LO, of the target terminal i _UEi The representation represents the latitude of the target terminal i.

2. And determining the horizontal coverage distance of the established base station in the train track direction according to the relative distance and the station track gauge. Wherein the horizontal coverage distance satisfies as shown in FIG. 6

D _gi Denotes the horizontal coverage distance, D _{Station gauge} Indicating the station gauge.

3. And fitting the horizontal coverage distance and the uplink edge rate of the PDCP layer to determine a first fitting curve. Wherein the first fitting curve satisfies

Represents a horizontal coverage distance corresponding to an uplink edge rate of the PDCP layer>

Indicating the uplink edge rate of the PDCP layer of the target terminal i.

Specifically, the horizontal coverage distance and the uplink edge rate of the PDCP layer are fitted according to a logarithmic fit or a polynomial fit, and a Root Mean Squared Error (RMSE) and a degree of curve fitting of each fitted curve are calculated.

Illustratively, the fitted curve with the maximum curve fitting degree and the minimum RMSE is selected as the first fitted curve, and the corresponding relationship between the horizontal coverage distance and the uplink edge rate of the PDCP layer in the first fitted curve is shown in fig. 7.

And fourthly, determining the uplink station spacing of the established base station according to the overlapping coverage distance of the established base station and the first fitted curve. Wherein the inter-station distance of the established base station satisfies

Indicates the uplink inter-station distance, D _cd Indicating the overlap coverage distance.

Illustratively, the correspondence between the station spacing, the station height, the station track gauge and the uplink edge rate of the PDCP layer is shown in table 6.

TABLE 6

And S172, carrying out interpolation calculation on the relative station height, the uplink station spacing and the station track gauge of the established access network equipment to determine a first table.

Specifically, in practical application, because the obtained relative station height, the uplink station spacing and the station track gauge of the established access network device are not continuous, interpolation calculation needs to be performed on the relative station height, the uplink station spacing and the station track gauge of the established access network device according to any one of polynomial interpolation, spline difference, piecewise interpolation and triangular interpolation, so that the network data is continuous, and the first table is generated according to the continuous relative station height, the uplink station spacing and the station track gauge of the established access network device.

For example, the first table is determined by performing interpolation calculation on the relative station height, the uplink station spacing and the station track gauge of the established access network device according to a triangular interpolation value, and the specific implementation process is as follows:

a three-dimensional coordinate system as shown in fig. 8 is established. Wherein, O represents the coordinate origin, the X axis represents the relative station height, the Y axis represents the station track gauge of the established access network equipment, and the Z axis represents the uplink station spacing.

Each data pair in table 6 is converted into a coordinate point in the three-dimensional coordinate system shown in fig. 8, and each coordinate point is substituted into the three-dimensional coordinates shown in fig. 8.

The trigonometric difference calculation is performed for each coordinate point in the three-dimensional coordinates shown in fig. 8 in turn. Specifically, the process of calculating the triangular difference value is as follows:

any one of the three-dimensional coordinates shown in fig. 8 is selected, as the point P1. Two coordinate points closest to the point P1 are calculated. (e.g., point P2 and point P3), wherein the coordinate points corresponding to any one of the point P1, the point P2 and the point P3 all belong to the coordinate points corresponding to the data pairs (including station height, uplink inter-station distance and station track distance) in table 6.

For example, the coordinate values of the point P1, the point P2, and the point P3 are shown in table 7.

TABLE 7

As shown in fig. 8, a triangle can be determined according to the point P1, the point P2, and the point P3. Wherein, three vertexes of the triangle are respectively a point P1, a point P2 and a point P3.

Note that the triangle determined from the point P1, the point P2, and the point P3 is a 2D graph. For the purpose of visualizing the triangle defined by the viewpoint P1, the point P2 and the point P3, a rectangular coordinate system is established as shown in FIG. 9. Wherein the Y axis is parallel to the P2P3 side of the triangle, the X axis is perpendicular to the Y axis and is in the plane of the triangle, the X axis represents the relative station height, and the Y axis represents the station track distance of the established access network equipment.

In practical applications, any point P (H _ n, D) within the triangle _{Station gauge _ m} ) There are two degrees of freedom, u and v respectively. Since the degree of freedom u and the degree of freedom v represent the weight contribution of each vertex to a specific region, and (1-u-v) is the third weight, each vertex pair point P (H _ n, D) of the triangle can be calculated by calculating the degree of freedom u and the degree of freedom v _{Station gauge _ m} ) The contribution of (c).

In particular, the current point

When the angle is within the triangle, the degree of freedom u and the degree of freedom v must satisfy the condition u is more than or equal to 0, v is more than or equal to 0, and u + v is less than or equal to 1.

Then, for the graph shown in FIG. 9Any point P (H _ n, D) in the triangle of (1) _{Station gauge _ m} ) Go through the traversal to determine each point P (H _ n, D) _{Station gauge _ m} ) Corresponding degrees of freedom u and v, and each point P (H _ n, D) _{Station gauge _ m} ) And corresponding uplink station spacing.

Specifically, for any point P (H _ n, D) in the triangle shown in fig. 9 _{Station gauge _ m} ) The traversal process is performed as follows:

since the point P1, the point P2, the point P3 and the point P (H _ n, D) are known _{Station gauge _ m} ) The degree of freedom u and the degree of freedom v are solved, and only a linear equation of two-dimensional needs to be solved:

h _ n = (1-u-v) × P1 (H) + u × P2 (H) + v × P3 (H), formula one.

D _{Station gauge _ m} ＝(1-u-v)×P1(D _{Station gauge} )+u×P2(D _{Station gauge} )+v×P3(D _{Station gauge} ) And a formula II.

Where H _ n represents the station height of point P, D _{Station gauge _ m} Represents the station gauge of point P, PN (H) represents the station height of point PN, PN (D) _{Station gauge} ) Representing the station track gauge of point PN, N being an integer greater than 0.

Illustratively, when N is equal to 1, PN (H) represents the station height of point P1, (N (D) _{Station gauge} ) Representing the up track gauge of point P1.

From the first and second equations, the point P (H _ n, D) is known _{Station gauge _ m} ) The corresponding degree of freedom u and the degree of freedom v, so that the point P (H _ n, D) can be determined according to the formula three _{Station gauge _ m} ) And corresponding uplink station spacing.

representing the uplink inter-station distance of point PN.

Illustratively, when N is equal to 1,

the uplink inter-station distance of point P1 is shown.

In particular, according to each point P (H _ n, D) _{Station gauge _ m} ) Corresponding uplink station spacing can determine a three-dimensional coordinate point

At this time, one-time interpolation of the relative station height obtained in S170, the uplink inter-station distance obtained in S171, and the station track gauge of the established access network device is completed.

Further, when all the interpolation of the relative station height obtained in S170, the uplink inter-station distance obtained in S171, and the station track gauge of the established access network device is completed, the first table may be determined by summarizing the data.

Specifically, in order to more vividly show the corresponding relationship among the station height, the uplink station spacing and the station track gauge of the base station to be built, the method for determining the station spacing provided by the embodiment of the present invention is based on the colors of the point P1, the point P2 and the point P3, and the three-dimensional coordinate point

U and v, three-dimensional coordinate points can be determined

The specific implementation process of the color of (1) is as follows:

suppose a three-dimensional coordinate point determined from the point P1, the point P2, and the point P3

With a degree of freedom u equal to 0.4 and a degree of freedom v equal to 0.5; the color of the point P1 is red, the color of the point P2 is green, and the color of the point P3 is blue, and the chromaticity of red is known by a color editor in matrix laboratories (Matlab)The chromaticity of green is (0, 255), the chromaticity of green is (0, 255, 0), and the chromaticity of blue is (255, 0). Therefore, the chromaticity corresponding to the point P1 is (0, 255), the chromaticity corresponding to the point P2 is (0, 255, 0), and the chromaticity corresponding to the point P3 is (255, 0).

Then three-dimensional coordinate points

In the corresponding chromaticity (a, b, c), a = (1-u-v) × P1 (a) + u × P2 (a) + v × P3 (a), b = (1-u-v) × P1 (b) + u × P2 (b) + v × P3 (b), and c = (1-u-v) × P1 (c) + u × P2 (c) + v × P3 (c).

Wherein PN (a) represents a value of a in chromaticity of the point PN, PN (b) represents a value of b in chromaticity of the point PN, PN (c) represents a value of c in chromaticity of the point PN, and N is an integer greater than 0.

Illustratively, when N is equal to 1, since the chromaticity of the point P1 is (0, 255), a =0, b =0, c =255.

From the above, the three-dimensional coordinate points

Corresponding a = (1-0.4-0.5) × 0+0.4 × 0+0.5 × 255= 127.5) in chromaticity (a, b, c), b = (1-0.4-0.5) × 0+0.4 × 255= 0.5 × 0+ 102, g = (1-0.4-0.5) × 255+0.4 × 0+0.5 × 0=25.5, namely three-dimensional coordinate point

The corresponding chromaticity is (127.5, 102, 25.5).

Then, three-dimensional coordinate points are set

The corresponding chromaticity (127.5, 102, 25.5) is brought into the color editor in Matlab so that the color of point P can be determined.

Note that the point P (H _ n, D) _{Station gauge _ m} ) Corresponding color and three-dimensional coordinate points

Is the same, i.e. point P (H _ n, D) _{Station gauge _ m} ) Corresponding chromaticity and three-dimensional coordinate points

The corresponding chromaticities are the same.

All points P (H _ n, D) _{Station gauge _ m} ) And each point P (H _ n, D) _{Station gauge _ m} ) The corresponding colors are summarized to obtain the color distribution in the triangle as shown in fig. 9, so that the user can more vividly know the corresponding relationship among the station height, the uplink station spacing and the station track gauge of the base station to be built.

Alternatively, the first and second electrodes may be,

all three-dimensional coordinate points are measured

And each three-dimensional coordinate point->

The corresponding colors are summarized to obtain an equal height map as shown in fig. 10, so that a user can more vividly know the corresponding relation among the station height, the uplink station spacing and the station track gauge of the base station to be built.

Illustratively, the interpolation of the relative station height, the uplink station spacing, and the station track gauge of the established access network device is performed according to triangular interpolation, and the first table is determined as shown in table 8.
