As shown in fig. 1, a conventional distributed antenna architecture is composed of three parts: core network 10, CPU11, antenna access unit AP 12. The traditional network architecture deployment mode is divided into two parts: an active antenna processing unit AAU or a radio remote unit RRU at the edge; and the core network, wherein the base station adopts a panel antenna, RF and a baseband processing unit BBU. However, the distributed antenna proposed by the current 6G is still in the architecture stage, and the use of adaptive adjustment of antenna angles for different wireless nodes is not considered yet, and the network quality cannot be effectively improved, so that the problem of cross-zone coverage is caused, the spectrum resources cannot be reasonably used, and the utilization rate of the network resources is low.

As a possible implementation, it is proposed that the antenna angle parameter allocating unit is specifically configured to send the selected antenna angle parameter to different wireless nodes in a signaling mode, for example: the antenna downtilt angle of the wireless node 1 is An_D1The horizontal angle of the antenna is An_H1(ii) a The antenna downtilt angle of the wireless node 2 is An_D2The horizontal angle of the antenna is An_H2(ii) a The antenna downtilt angle of the wireless node 3 is An_D3The horizontal angle of the antenna is An_H3；。

where N is the number of wireless nodes connected in all CPUs, f_i ^k(D_ij) For interference of wireless node j to wireless node i, Inf^K _iThe average value of the interference of the wireless node i on all other wireless nodes under the CPU is obtained.

And if the terminal is a satisfactory terminal, calculating the number ratio of the satisfactory terminals as follows:

and if the number of the satisfied terminals exceeds 90%, selecting the antenna angle parameter configuration, and if not, selecting the antenna angle parameter configuration corresponding to the second minimum interference.

Specifically, in the wireless node interference-attenuation calculation algorithm, the added wireless node has a certain influence on the original node, generally, the interference gradually increases along with the increase of the wireless node, then the interference tends to a relevant high value, the area throughput is increased and then decreased, and referring to the area limit capacity model given above, the attenuation degree of the wireless node-wireless node needs to be determined. However, the existing network environment and network simulation are basically not realized, and calculation needs to be performed by using a mathematical modeling mode.

First, a relationship between the user distribution distance and the serving wireless node is established, and assuming that the transmitted channels are consistent, the user selects the wireless node whose wireless access is based only on the signal strength, i.e., the wireless node with the closest access distance. The distribution of serving wireless nodes to users may be represented using the following equation:

Lemma1：PDF f_Rmis a function of the distance distribution between the user and the wireless node:

f_Rm(r)＝2πλ_mr exp(-πλ_mr²) Formula four

Wherein λ is_mIs the density of wireless nodes, in km²And Rm is the distance from the user to the wireless node m.

Secondly, a probability function of the wireless access of the user is calculated, and the user is assumed to be possibly accessed to the wireless node. When in use

And accessing the small base station m by the user, wherein RM and Rm are distances from the user to the nearest wireless node MaBS and the wireless base station MiBS. The probability of a user accessing a given small cell is given by:

lemma.2: probability distribution function for a user to access a given wireless node:

and then, calculating the interference among the wireless nodes, wherein after the terminal accesses one wireless node, the signals of other wireless nodes all have interference to the terminal, so that for one terminal, the interference can be represented by the following formula:

wherein, B₀Is the wireless node to which the terminal is connected, r_iIs the ith MiBS (not the accessing wireless node).

The interference distribution function can thus be obtained:

the formula five is calculated and obtained according to a specified model, and the total interference on the wireless node connected with the terminal in a certain area can be obtained through the formulas from four to seven, assuming that A is_m＝A_MWhen the value is 4, then

Where an approximating function is used for acquisition.

Further, an implementation manner for configuring and calculating the uplink and downlink throughput to be obtained of each terminal by using an antenna angle parameter is provided, and the interference value obtained by a single terminal and the useful signal (which may be SS-RSRP or obtained from SSB signaling) obtained by the terminal according to the above formula six may obtain corresponding SINR values at different frequencies: SS _ SINR-SS _ RSRP-I, according to shannon's theorem, the relationship between SINR and throughput can be obtained, and the calculation formula is as follows:

T＝W×log₂(1+S/N)≈W×log₂equation ten of (1+ SINR)

Where T is throughput and W is power.

As a possible implementation, it is proposed that the antenna angle parameter allocation unit sends the selected antenna angle parameter to the different wireless nodes in a signaling mode, for example: the uplink frequency point of the wireless node 1 is f_upThe downlink frequency point is f_downPower of W₁。

In a design, in order to obtain data requirement profile information, the antenna angle adaptive method of a distributed network architecture provided in the embodiment of the present invention may further include, after S601, the following S6011.

As a possible implementation manner, the downlink data contour extraction module is specifically configured to analyze the condition of the data sent by the core network by the CPU and obtain a demand contour of the data. Each terminal corresponds to a terminal downlink throughput, for example: the downlink throughput corresponding to the terminal 1 is T_down1The downlink throughput corresponding to the terminal 2 is T_down2The downlink throughput corresponding to the terminal 3 is T_down3。

Exemplarily, as shown in fig. 13, a signaling flow diagram corresponding to the terminal, the wireless node CPU and the core network in an uplink transmission phase is shown. The terminal extracts the data uploading requirement and collects the position information of the terminal, thereby adding the service summary and the position information of the terminal in the random access process and transmitting the service summary and the position information to the wireless node. And the wireless node inquires the adjustable range of the antenna angle which can be used for distribution, and encapsulates the adjustable range of the antenna angle of the wireless node and the information corresponding to the terminal into a random access signaling. The wireless node adds the antenna angle adjustable range and the terminal information of the wireless node in the random access process, sends the antenna angle adjustable range and the terminal information to the CPU, the CPU separates out a random access signaling, stores the antenna angle adjustable range and the terminal information of the wireless node, and then transmits the random access process to a core network. The CPU further calculates the antenna angle parameter configuration required by different wireless nodes and issues the calculated wireless node antenna angle parameter to the wireless nodes, so that the wireless nodes can carry out antenna angle parameter configuration according to the parameter issued by the CPU and send a configuration completion signaling to the CPU, and meanwhile, the CPU confirms that the configuration is completed to a core network so as to transmit uplink and downlink data.

Further exemplarily, as shown in fig. 14, a signaling flow diagram corresponding to the terminal, the wireless node CPU and the core network at the downlink transmission stage is shown. When downlink data reaches a core network, the core network transmits a paging signaling to the CPU, the CPU further transmits the paging signaling to the wireless node, and the wireless node further transmits the paging signaling to the terminal so as to trigger the terminal to acquire the position information of the terminal, add the position information of the terminal in the random access process and transmit the position information to the wireless node. And the wireless node inquires the adjustable range of the antenna angle which can be used for distribution, and encapsulates the adjustable range of the antenna angle of the wireless node and the information corresponding to the terminal into a random access signaling. The wireless node adds the antenna angle adjustable range and the terminal position information of the wireless node in the random access process, and sends the antenna angle adjustable range and the terminal position information to the CPU, so that the CPU separates out a random access signaling, stores the antenna angle adjustable range and the terminal position information of the wireless node, and then transmits the random access process to a core network. The core network transmits the prior data to the CPU, the CPU stores the downlink data and extracts the profile of the downlink data so as to further calculate the antenna angle parameter configuration required by different wireless nodes, and transmits the calculated wireless node antenna angle parameter to the wireless nodes, so that the wireless nodes can carry out antenna angle parameter configuration according to the parameter transmitted by the CPU, and transmit a configuration completion signaling to the CPU so as to transmit the uplink data and the downlink data.

In the embodiment of the invention, by further strengthening the 6G distributed antenna architecture, from the uplink triggering angle and the downlink triggering angle respectively, different wireless nodes can be integrated into the 6G distributed antenna architecture by configuring the technology of differentiated antenna downward inclination angles and antenna horizontal angles, and the functions of the terminal, the wireless nodes and the CPU are strengthened, so that the requirement of joint distributed deployment of adaptive adjustment of the antenna angles is realized, and the target centering on a user is met. Considering that different antenna downtilt angles and antenna horizontal angle configuration parameters can meet the conditions of different users and have certain interference isolation, the method aims to achieve the requirements of interference elimination and user requirement meeting by adjusting the antenna downtilt angles and the antenna horizontal angles of different nodes.
