The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in the embodiments of the present invention, the words "first", "second", and the like are used to distinguish the same items or similar items with basically the same functions and actions, and those skilled in the art can understand that the words "first", "second", and the like do not limit the quantity and execution order.

Fig. 1 is a simplified schematic diagram of a system architecture to which an embodiment of the present invention may be applied, as shown in fig. 1, the system architecture may include:

the method for determining the downlink edge coverage 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-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 on a subband k from a base station through an antenna, the symbol is first subjected to signal processing by a shaping filter to obtain a processed signal, then a CP of the signal is removed, then the CP-removed signal is subjected to Fast Fourier Transform (FFT) according to a carrier interval k, and then Orthogonal Frequency Division Multiplexing (OFDM) detection is performed on the subband i of the FFT-signal-processed signal, so that the symbol carried on the subband k and sent by the antenna receiving base station is converted into a signal recognizable to the terminal. In the embodiment of the present invention, the determining device of the signal to interference plus noise ratio may be a base station or a base station controller of wireless communication, etc.

In the embodiment of the present invention, the base station may be a base station (BTS) in a global system for mobile communication (GSM), a Code Division Multiple Access (CDMA), a base station (node B, NB) in a Wideband Code Division Multiple Access (WCDMA), a base station (evolved dnb, eNB) in a Long Term Evolution (Long Term Evolution, LTE), an internet of things (internet of things, IoT) or a narrowband internet of things (NB-IoT), a base station in a future 5G mobile communication network or a future evolved public land mobile network (public land mobile network, PLMN), which is not limited in any way.

Terminals are used to provide voice and/or data connectivity services to users. The terminal may be referred to by different names, such as User Equipment (UE), access terminal, terminal unit, terminal station, mobile station, remote terminal, mobile device, wireless communication device, vehicular user equipment, terminal agent or terminal device, and the like. Optionally, the terminal may be various handheld devices, vehicle-mounted devices, wearable devices, and computers with communication functions, which is not limited in this embodiment of the present invention. 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 downstream edge rate and the downstream 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 4K, 8K high-definition video and other uploading or downloading services on the downlink edge rate are shown in table 2.

TABLE 2

The third type of service is Virtual Reality (VR) (8k), high definition map downloading, and the like. The requirements of services such as VR (8k) high-definition map downloading on the downlink edge rate are shown in table 3.

TABLE 3

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 accuracy of the downlink edge coverage rate cannot be ensured by configuring the downlink edge coverage rate according to personal experience. Therefore, the embodiment of the present invention provides a method for determining downlink edge coverage, which introduces details on how to calculate downlink edge coverage.

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:

s11, obtaining a downlink edge rate of a Packet Data Convergence Protocol (PDCP) layer of the base station to be built.

Specifically, in practical application, when an operator is in a base station to be established, the operator determines the rated downlink edge rate of the PDCP layer according to the service type that can be initiated by the target terminal and the requirement of the downlink edge rate of the PDCP layer corresponding to each service type.

Illustratively, when the service type initiated by the test terminal is a video session, the preset downlink edge rate of the PDCP layer is 256kbps as can be seen from table 1.

Illustratively, the rated downlink edge rate of the PDCP layer is the maximum downlink edge rate among the downlink edge rates of the PDCP layers corresponding to the service type initiated by the user in the base station to be established.

S12, simulating the base station to be built, and determining the predicted signal to interference plus noise ratio (SINR).

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 SINR of the base station to be built is obtained.

Illustratively, taking an application scenario of the base station to be established as a high-speed rail scenario as an example, obtaining the predicted SINR 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. Wherein, the base station parameters comprise information of 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 SINR of each simulation, and recording (s, C, h, d, num, v, SINR). 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 rate of the user, and SINR is the SINR value of the user.

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

S13, determining the downlink edge coverage rate of the base station to be built according to the predetermined formula, the predicted SINR and the rated downlink edge rate of the PDCP layer. The preset formula includes a corresponding relationship among a downlink edge rate, an SINR and a downlink edge coverage of the PDCP layer.

Specifically, the method for determining the coverage of the downlink edge according to the embodiment of the present invention determines the preset formula according to the SINR of all target terminals and the downlink edge rate of the PDCP layer by acquiring the network data acquired by the target terminal within the coverage of at least one established base station. The method for determining the coverage rate of the downlink edge provided by the embodiment of the invention further comprises the following steps:

and S14, acquiring the network data collected by at least one target terminal. The network data comprises the downlink edge rate of the PDCP layer of the target terminal and the SINR of the target terminal, 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 the preset rate.

Specifically, in the method for determining the downlink edge coverage provided in 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.

Specifically, in order to ensure the accuracy of the preset formula, network data acquired by target terminals within the coverage area of a plurality of established base stations may be acquired, so as to ensure the accuracy of the downlink edge coverage rate determined according to the preset formula.

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 formula better conforms to the actual distribution, that is, the operator can accurately determine the downlink edge coverage of the base station to be established according to the preset formula.

When the number of the target terminals in the coverage range of each established base station is certain and the number of the established base stations is larger, the determined preset formula is more consistent with the actual distribution, namely, the operator can accurately determine the downlink edge coverage rate of the base station to be established according to the preset formula.

S15, determining a preset formula according to the SINR of each target terminal in at least one target terminal and the downlink edge rate of the PDCP layer.

Specifically, in practical application, the network data collected by each target terminal in each established base station is collected, and the network data is screened according to a moving speed greater than or equal to a preset speed (for example, the preset speed is 250km/h), so that the network data collected by the target terminals on the high-speed train is screened.

Specifically, the corresponding relationship between the SINR of the target terminal and the downlink edge rate of the PDCP layer of the target terminal in the network data acquired by each target terminal is shown in table 4.

TABLE 4

Target terminal number	RSRP	Downlink edge rate of PDCP layer
			Target terminal 1	-90dB	5Mbit/s
Target terminal 2	-110dB	2Mbit/s
			Target terminal N	-88dB	10Mbit/s

Specifically, S15 includes:

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

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

And S151, determining the downlink edge coverage rate according to the first probability and the second probability. Wherein the content of the first and second substances,

P_DLindicating the downlink edge coverage.

S152, fitting the downlink edge coverage rate, the SINR of each target terminal in the at least one target terminal and the downlink edge rate of the PDCP layer, and determining a preset formula. Wherein the preset formula satisfies

Representing the downlink edge rate of the PDCP layer, p00, p01, p10, p11, and p20 are all constants.

Illustratively, the correspondence relationship among the downlink edge rate, SINR, and downlink edge coverage of the PDCP layer is shown in table 5.

TABLE 5

Specifically, in practical application, after obtaining the preset formula, the operator may determine the downlink edge coverage of the base station to be established according to the preset formula, the predicted SINR, and the rated downlink edge rate of the PDCP layer.

Specifically, the downlink edge coverage, SINR of each target terminal in the at least one target terminal, and downlink edge rate of the PDCP layer are fitted according to any one of linear fitting, exponential fitting, and polynomial fitting, so as to determine the preset formula.

Illustratively, the data screening is performed according to gaussian distribution by fitting the downlink edge coverage, the SINR of each target terminal in the at least one target terminal, and the downlink edge rate of the PDCP layer, so as to obtain effective data with a confidence interval of 95%. Then, 95% of the obtained valid data is fitted according to polynomial fitting, thereby obtaining a fitted curve of a preset formula as shown in fig. 5. Wherein SINR _ DL represents SINR of the target terminal, DL represents downlink edge rate of PDCP layer of the target terminal, and PDL _ SINR represents downlink edge coverage.

In fig. 5, the fitting curves of each preset formula have the following value ranges of p00, p01, p10, p11 and p 20:

p00∈[0.8218，0.8781]，p01∈[-0.01012，-0.008606]，p10∈[0.02076，0.03396]，p11∈[2.246e-06，7.879e-05]，p20∈[-0.001555，-0.0008289]。

when the fitted curve of each preset formula in fig. 5 is calculated for the Root Mean Square Error (RMSE), the fitted curve of the preset formula is determined to have the optimum degree of curve fitting and RMSE when p00 ═ 0.85, p01 ═ 0.009364, p10 ═ 0.02736, p11 ═ 4.052e-05, and p20 ═ 0.001192. Wherein the curve fit is 0.9914 and the RMSE is 0.01663.

It should be noted that, when an operator determines the downlink edge coverage of the base station to be established according to the method for determining the downlink edge coverage provided in the embodiment of the present invention, if the downlink edge coverage is smaller than the preset threshold, the operator needs to adjust the SINR and/or the downlink edge rate of the PDCP layer until the calculated downlink edge coverage is greater than or equal to the preset threshold, so as to ensure user experience.

Further, in this embodiment of the present invention, with reference to fig. 2, as shown in fig. 3, the method for determining reference signal received power provided by this embodiment of the present invention further includes: s14 and S15.

Further, in the embodiment of the present invention, in combination with fig. 2, as shown in fig. 4, the above S15 may include S150, S151, and S152.
