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-baseband (baseband) k (where the symbol refers to information that needs to be transmitted by a base station), then, performing Inverse Fast Fourier Transform (IFFT) on the symbol according to a carrier spacing (subcarrier) k to obtain a signal k, further adding (add) a cyclic redundancy code (cyclic redundancy, CP) k to the signal k, and then, performing signal processing on the signal k to which the CPk is added by using a beamforming filter (beamforming filter), thereby obtaining a signal k after beamforming is performed on the kth transmission link. 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 (RX) a symbol carried in a sub-baseband k 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 Fast Fourier Transform (FFT) is performed on the CP-removed signal according to a carrier interval k, and Orthogonal Frequency Division Multiplexing (OFDM) detection is performed on the sub-baseband i of the FFT-signal-processed signal, so that the symbol carried in the sub-baseband k and transmitted by the antenna receiving base station is converted into a signal recognizable to the terminal.

In an embodiment of the present invention, the determining device of the edge rate may be a base station (BTS) in a global system for mobile communications (GSM), a base station (NB) in a Code Division Multiple Access (CDMA), a base station (node B, NB) in a Wideband Code Division Multiple Access (WCDMA), an eNB in a Long term evolution (Long term evolution, LTE), an eNB in an internet of things (IoT) or a narrowband internet of things (NB-IoT), a base station or a base station controller in a future 5G mobile communication network or a future evolved Public Land Mobile Network (PLMN), and the like, and the embodiments of the present invention do not limit this.

For example, the handheld device may be a smartphone. The in-vehicle device may be an in-vehicle navigation system. The wearable device may be a smart bracelet. The computer may be a Personal Digital Assistant (PDA) computer, a tablet computer, and a laptop computer.

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

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

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.

TABLE 1

The second type of service is uploading or downloading type services such as 4K and 8K high-definition videos. The requirements of the uploading or downloading services such as 4K and 8K high-definition videos on the uplink edge rate are shown in table 2.

TABLE 2

			4K high definition video	/	20Mbps

			VR(8K)	/	50Mbps

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 building a new base station, the edge rate is configured by depending on personal experience, so that the accuracy of the edge rate cannot be ensured. To this end, the embodiment of the present invention provides a method for determining an edge rate, which describes how to calculate an edge rate in detail.

Specifically, as shown in fig. 2, taking the device to be accessed as the base station to be established and the established device to be accessed as the established base station as an example, the method may include the following steps S11 to S13:

and S11, obtaining the rated edge coverage rate of the base station to be built.

Specifically, in practical application, when an operator is at a base station to be established, the operator may select a rated edge coverage of the base station to be established according to a scenario in which the base station to be established is applied, such as: when the application scene of the base station to be built is a high-speed rail scene, the rated edge coverage rate of the base station to be built is 90% or 95%.

And S12, simulating the base station to be built, and determining the predicted Reference Signal Received Power (RSRP).

Specifically, in order to determine that the base station to be built can provide service guarantees for each user in the coverage area after deployment, planning simulation needs to be performed according to the environment where the base station to be built is located, that is, simulation is performed according to a scene map (such as a three-dimensional (3-dimensional, 3D) map or a planning map) of the coverage area of the base station to be built and base station parameters of the base station to be built, so that the predicted RSRP of the base station to be built is obtained.

For example, taking an application scenario of a base station to be established as a high-speed rail scenario as an example, obtaining a predicted RSRP of the base station to be established includes:

1. and (4) using planning software to import a scene map, plan the situation of the high-speed rail line and base station parameters of the base station to be built. The base station parameters include information such as station address, station height, station spacing and the like.

2. The simulation model is set according to the high-speed rail acquisition channel model in the third Generation Partnership Project (3 rd Generation Partnership Project, 3 GPP).

3. And (5) carrying out mobile simulation of a single user according to the mobile speed of more than or equal to 250km/h, acquiring the RSRP of each simulation, and recording (s, C, h, d, num, v, RSRP). Note: s is the device type, C is the channel model, h is the station height, d is the station spacing, num is the number of the user, v represents the moving speed of the user, and RSRP is the RSRP value of the user.

It should be noted that, when performing user spot simulation, each user corresponds to one target terminal.

And S13, inquiring a preset table configured in advance according to the predicted RSRP and the rated edge coverage rate, and determining the edge rate of the base station to be established. The preset table comprises a corresponding relation among the RSRP, the edge coverage rate and the edge rate.

Specifically, when the edge coverage is the uplink edge coverage and the edge rate is the uplink edge rate, S13 includes: s130, inquiring a preset table configured in advance according to the predicted RSRP and the rated uplink edge coverage rate, and determining the uplink edge rate of the base station to be built.

Specifically, in the method for determining an edge rate provided in the embodiment of the present invention, a preset table is determined according to RSRP of all target terminals and an uplink edge rate of a Packet Data Convergence Protocol (PDCP) layer by obtaining network data acquired by a target terminal within a coverage area of at least one established base station. The method for determining the edge rate provided by the embodiment of the invention further comprises the following steps:

and S14, acquiring the network data of at least one target terminal. The network data comprises RSRR of a target terminal and an uplink edge rate of a packet data convergence protocol PDCP layer, the target terminal is located in the coverage range of the established base station, and the moving rate of the target terminal is greater than a preset rate.

S15, determining a preset table according to the RSRP of each target terminal in at least one target terminal and the uplink edge rate of the PDCP layer.

Specifically, in order to ensure that the accuracy of the actually obtained preset table is higher, a large amount of network data acquired by a target terminal in the coverage area of each base station in at least one established base station under different parameters such as the inter-station distance, the station track gauge and the station height needs to be acquired 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:

A5G terminal is placed on the side of a high-speed rail passageway, User Datagram Protocol (UDP) uplink service is initiated and maintained through the 5G terminal, and drive test software records related data (a timestamp, a Physical Cell Identifier (PCI), the moving speed of the 5G terminal, RSRP and the uplink edge speed of a 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.

Illustratively, the network data is shown in table 4.

TABLE 4

For example, when the preset speed is 250km/h, the target terminals with the moving speed greater than 250km/h may be screened, so as to determine that the network data collected by the target terminals on the high-speed train is as shown in table 5.

TABLE 5

Target terminal number	RSRP	Uplink edge rate of PDCP layer
			Target terminal 1	-90dBm	0.5Mbps/s
Target terminal 2	-110dBm	1.5Mbps/s
			Target terminal 3	-88dBm	5Mbps/s

Specifically, S15 includes:

s150, determining a first probability and a second probability according to the RSRP of each target terminal in at least one target terminal and the uplink edge rate of the PDCP layer. Wherein,

p1 denotes a first probability, P2 denotes a second probability, N1 denotes a total number of target terminals of which RSRP is greater than a specified threshold among the at least one target terminal and an uplink edge rate of the PDCP layer is greater than an uplink rate threshold, N2 denotes a total number of target terminals, and N3 denotes a total number of target terminals of which RSRP is greater than a specified threshold among the at least one target terminal.

And S151, determining the uplink edge coverage rate according to the first probability and the second probability. Wherein,

P_ULindicating the uplink edge coverage.

S152, performing interpolation calculation according to the uplink edge coverage rate, the RSRP of each target terminal in the at least one target terminal and the uplink edge rate of the PDCP layer, and determining at least one data pair. Wherein the data pairs comprise RSRP, uplink edge coverage and uplink edge rate.

And S153, determining a preset table according to the at least one data pair.

For example, the correspondence between RSRP, uplink coverage and uplink edge rate of the PDCP layer in the network data collected by the target terminal is shown in table 6.

Specifically, in practical applications, since network data acquired by the target terminal is discontinuous, interpolation calculation needs to be performed on the uplink edge coverage, the RSRP of each target terminal in the at least one target terminal, and the uplink edge rate of the PDCP layer according to any one of polynomial interpolation, spline difference, piecewise interpolation, and triangular interpolation, so that the network data is continuous, and a preset table is generated according to the continuous network data.

TABLE 6

For example, the specific implementation process is as follows, by taking the example of performing interpolation calculation on the uplink edge coverage, RSRP of each target terminal in at least one target terminal, and uplink edge rate of the PDCP layer according to triangular interpolation, and determining a preset table:

a three-dimensional coordinate system as shown in fig. 5 is established. Wherein, O represents the origin of coordinates, the X-axis represents RSRP, the Y-axis represents uplink coverage, and the Z-axis represents uplink edge rate.

Each data pair in table 6 is converted into a coordinate point in the three-dimensional coordinate system shown in fig. 5, and each coordinate point is substituted into the three-dimensional coordinates shown in fig. 5.

The trigonometric difference calculation is performed for each coordinate point in the three-dimensional coordinates shown in fig. 5 in turn. Specifically, the process of calculating the triangular difference value is as follows:

any one of the three-dimensional coordinates shown in fig. 5 is selected, such as 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 point P1, point P2 and point P3 all belong to the coordinate points corresponding to the data pairs in Table 6.

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

TABLE 7

Coordinate point	RSRP	Upstream edge rate	Uplink edge coverage
				Point P1	RSRP_1	S^UL_1	Pr_1
Point P2	RSRP_2	S^UL_2	Pr_2
				Point P3	RSRP_1	S^UL_2	Pr_3

As shown in FIG. 5, a triangle can be determined from the points P1, P2, and P3. The three vertexes of the triangle are respectively a point P1, a point P2 and a point P3.

It should be noted that the triangle determined by the point P1, the point P2, and the point P3 is a 2D graph. For the triangle defined by the viewpoint P1, the point P2, and the point P3 of the figure, a rectangular coordinate system is established as shown in fig. 6. Wherein the Y-axis is parallel to the P2P3 side of the triangle, the X-axis is perpendicular to the Y-axis and lies in the plane of the triangle, the X-axis represents RSRP and the Y-axis represents uplink coverage.

In practical applications, there are two degrees of freedom for any one point P (RSRP _ n, Pr _ nm) within the triangle, i.e., degree of freedom u and degree of freedom v. 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, the contribution of each vertex of the triangle to the point P (RSRP _ n, Pr _ nm) can be calculated as long as the degree of freedom u and the degree of freedom v are calculated.

Specifically, current point P (RSRP _ A, S)^ULB, Pr C) within the triangle, the degree of freedom u and the degree of freedom v must satisfy the condition u ≥ 0, v ≥ 0, u + v ≤ 1.

Then, any point P (RSRP _ n, Pr _ nm) in the triangle shown in fig. 6 is traversed to determine the degree of freedom u and the degree of freedom v corresponding to each point P (RSRP _ n, Pr _ nm) and the upstream edge rate corresponding to each point P (RSRP _ n, Pr _ nm).

Specifically, the traversal process for any point P (RSRP _ n, Pr _ nm) in the triangle shown in fig. 6 is as follows:

since the coordinate values of the point P1, the point P2, the point P3 and the point P (RSRP _ n, Pr _ nm) are known, the degree of freedom u and the degree of freedom v are solved by only solving the linear equation of two-dimentional system:

RSRP _ n is (1-u-v) × P1(RSRP) + u × P2(RSRP) + v × P3(RSRP), formula one.

Pr _ nm ═ 1-u-v) × P1(Pr) + u × P2(Pr) + v × P3(Pr), formula two.

Wherein RSRP _ N represents RSRP of a point P, Pr _ nm represents uplink edge coverage of the point P, PN (RSRP) represents RSRP value of a point PN, PN (Pr) represents uplink edge coverage of the point PN, and N is an integer greater than 0.

Illustratively, when N is equal to 1, PN (RSRP) represents RSRP for point P1, and PN (Pr) represents uplink coverage for point P1.

According to the first formula and the second formula, the degree of freedom u and the degree of freedom v corresponding to the point P (RSRP _ n, Pr _ nm) can be known, so that the uplink edge rate corresponding to the point P (RSRP _ n, Pr _ nm) can be determined according to the third formula.

S^UL_m＝(1-u-v)×P1(S^UL)+u×P2(S^UL)+v×P3(S^UL) And a formula III. Wherein S is^ULM denotes the upstream edge rate.

Specifically, a three-dimensional coordinate point P (RSRP _ n, S) may be determined according to the uplink edge rate corresponding to each point P (RSRP _ n, Pr _ nm)^ULMm, Pr nm), at this time, completing one interpolation of the network data collected by the target terminal.

Further, when all interpolation of the network data collected by the target terminal is completed, the preset table can be determined by summarizing the data.

Specifically, in order to more vividly show the corresponding relationship among the RSRP, the edge coverage and the edge rate of the base station to be built, the edge rate determining method provided in 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 P (RSRP _ n, S)^ULM, Pr nm) and a degree of freedom u and v, a three-dimensional coordinate point P (RSRP _ n, S) can be determined^ULM, Pr nm), the specific implementation process is as follows:

assume a three-dimensional coordinate point P (RSRP _ n, S) determined from the points P1, P2, and P3^ULM, Pr nm) is equal to 0.4, v is 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 (0, 0, 255) as can be seen by a color editor in matrix laboratories (Matlab),The chromaticity of green is (0, 255, 0), and the chromaticity of blue is (255, 0, 0). Therefore, the chromaticity corresponding to the point P1 is (0, 0, 255), the chromaticity corresponding to the point P2 is (0, 255, 0), and the chromaticity corresponding to the point P3 is (255, 0, 0).

The three-dimensional coordinate point P (RSRP _ n, S)^ULM, Pr _ nm) corresponding chromaticity (a, b, c), (1-u-v) × P1(a) + u × P2(a) + v × P3(a), (1-u-v) × P1(b) + u × P2(b) + v × P3 (b)), and (1-u-v) × P1(c) + u × P2(c) + v × P3 (c).

Wherein PN (a) represents the value of a in the chromaticity of the point PN, PN (b) represents the value of b in the chromaticity of the point PN, PN (c) represents the value of c in the 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, 0, 255), a is 0, b is 0, and c is 255.

From the above, the three-dimensional coordinate point P (RSRP _ n, S)^ULM, Pr _ nm) corresponding to chromaticity (a, b, c), where a ═ × 0 (1-0.4-0.5) 860 +0.4 × 0+0.5 × 255 ═ 127.5, b ═ 1-0.4-0.5) × 0+0.4 × 255+0.5 × 0 ═ 102, c ═ 1-0.4-0.5) × 255 (255 +0.4 × 0+0.5 × 0 ═ 25.5, i.e., three-dimensional coordinate point P (RSRP _ n, S _ nm), three-dimensional coordinate point P (RSRP _ n, S _ 5), and chromaticity (a, b, c) corresponding to m, Pr _ nm), and the chromaticity (a, b, c) corresponding^ULM, Pr nm) corresponds to a chromaticity of (127.5, 102, 25.5).

Then, the three-dimensional coordinate point P (RSRP _ n, S)^ULM, Pr nm) into a color editor in Matlab so that the color of point P can be determined.

Note that the color corresponding to the point P (RSRP _ n, Pr _ nm) and the three-dimensional coordinate point P (RSRP _ n, S)^ULM, Pr nm) of the same color, i.e., chromaticity corresponding to the point P (RSRP _ n, Pr nm) and the three-dimensional coordinate point P (RSRP _ n, S)^ULM, Pr nm) are the same.

The coordinate values of all the points P (RSRP _ n, Pr _ nm) and the color corresponding to each point P (RSRP _ n, Pr _ nm) are summarized, so that the color distribution in a triangle as shown in fig. 6 is obtained, and a user can more vividly know the corresponding relationship among the RSRP, the edge coverage and the edge rate of the base station to be built.

or ,

all three-dimensional coordinate points P (RSRP _ n)，S^ULM, Pr nm), and each three-dimensional coordinate point P (RSRP _ n, S)^ULM, Pr nm) to obtain an equal-height map as shown in fig. 7, so that a user can more vividly know the corresponding relationship among the RSRP, the edge coverage and the edge rate of the base station to be built.

Illustratively, the uplink edge coverage, RSRP of each target terminal in the at least one target terminal, and the uplink edge rate of the PDCP layer are interpolated according to triangular interpolation values, and a predetermined table is determined as shown in table 8.

TABLE 8

Specifically, when the edge coverage is the uplink edge coverage and the edge rate is the uplink edge rate, the operator may query a preset table configured in advance according to the predicted RSRP and the rated uplink edge coverage, and determine the uplink edge rate of the PDCP layer of the base station to be established.

Specifically, in order to ensure the accuracy of the preset table, network data acquired by target terminals within the coverage area of the multiple established base stations may be acquired, so as to ensure the accuracy of determining the uplink edge rate of the base station to be established by an operator according to the preset table.

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 preset table better conforms to the actual distribution, that is, the operator can accurately determine the uplink edge rate of the base station to be established according to the preset table.
