Due to deep intervention of industry users, a network architecture centered on stable service requirements will become a main trend of 6G air interface development, but the current network architecture is still in a manner centered on a base station, so that the deployment cannot meet the requirement of comprehensive deployment according to UE. 6G currently presents a distributed wireless network architecture that can address part of the user-centric needs. As shown in fig. 1, a conventional distributed antenna architecture is provided, and the distributed antenna architecture is composed of three parts: a core network 10, a CPU11, and an antenna access unit AP12.

Specifically, according to the wireless node interference-attenuation calculation algorithm, the addition of the wireless node has a certain influence on the original node, the interference is gradually increased along with the increase of the wireless node, then the interference tends to a relevant high value, the area throughput is gradually increased and then decreased, and the attenuation degree of the wireless node-wireless node needs to be determined by referring to the area limit capacity model. However, the current network environment and network simulation cannot be realized basically, and calculation is needed 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 wireless access based on signal strength only, i.e., the wireless node closest to the access distance. The distribution of serving wireless nodes and users may be represented using the following formula:
Lemma1：PDF f Rm is a distance distribution function between the user and the wireless node:
f Rm (r)＝2πλ m r exp(-πλ m r 2 ) Equation four
Wherein lambda is m For density of wireless nodes, unit km 2 Rm is the distance of the user to the wireless node m.
Second, a probability function of the user's access to the wireless is calculated, we assume that the user may be accessing the wireless node. When (when)
Figure BDA0003338127930000161
At that time, the user accesses the small base station m, where RM and RM are the distances of the user to the nearest radio node MaBS and radio base station MiBS. The probability of a user accessing a given small cell is given by:

and calculating interference among wireless nodes, wherein after the terminal is accessed to one wireless node, the signals of other wireless nodes have interference to the terminal, so that the interference to one terminal can be expressed by the following formula:
Figure BDA0003338127930000163
wherein B is 0 Is the radio node to which the terminal is connected, r i Is the i-th MiBS (not the wireless node of the access).
Thus, an interference distribution function can be obtained:
Figure BDA0003338127930000164
the fifth formula is calculated and obtained according to a specified model, and the total interference suffered by the wireless node connected with the terminal in a certain area can be obtained through the fourth formula to the seventh formula, and the assumption A is that m ＝A M =4, then
Figure BDA0003338127930000165
Figure BDA0003338127930000166
Wherein the approximation function is used here for the acquisition.
Further, an implementation manner is provided for calculating the throughput to be obtained for each terminal uplink and downlink according to a certain power configuration, where the interference value obtained by a single terminal and the useful signal obtained by the terminal (may be SS-RSRP or may be obtained from SSB signaling) obtained according to the above formula six may obtain corresponding SINR values under different frequencies: ss_sinr=ss_rsrp-I, according to shannon's theorem, the relation between SINR and throughput can be obtained, with the following calculation formula:
T＝W×log 2 (1+S/N)≈W×log 2 (1+SINR) formula ten
Where T is throughput and W is power.
As a possible implementation, it is proposed that the power allocation unit sends the selected power to different wireless nodes in a signalling pattern, for example: the uplink frequency point of the wireless node 1 is f up The downlink frequency point is f down The power is W 1 。

Exemplary, as shown in fig. 11, the signaling flow diagrams corresponding to the uplink transmission phase of the terminal, the wireless node CPU and the core network are shown. The terminal extracts the uploading data requirement and collects the position information of the terminal, so that the service summary and the position information of the terminal are added in the random access process and transmitted to the wireless node. The wireless node inquires the transmitting power which can be used for distribution, and encapsulates the transmitting power of the wireless node and the information corresponding to the terminal into the random access signaling. The wireless node adds the power and terminal information of the wireless node in the random access process, sends the information to the CPU, separates the random access signaling by the CPU, stores the power and terminal information of the wireless node, and then transmits the random access process to the core network. The CPU further calculates power configurations required by different wireless nodes and transmits the calculated wireless node configuration power to the wireless nodes, so that the wireless nodes can configure the power according to parameters transmitted by the CPU and transmit configuration completion signaling to the CPU, and meanwhile, the CPU confirms that the configuration is completed to the core network so as to transmit uplink data.
Also exemplary, as shown in fig. 12, the signaling flow diagrams corresponding to the terminal, the wireless node CPU and the core network in the downlink transmission stage are shown. When the downlink data arrives at the core network, the core network transmits 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, and the terminal is added in the random access process to transmit the position information to the wireless node. The wireless node inquires the transmitting power which can be used for distribution, and encapsulates the transmitting power of the wireless node and the information corresponding to the terminal into the random access signaling. The wireless node adds the power and terminal position information of the wireless node in the random access process and sends the information to the CPU, so that the CPU separates out the random access signaling, stores the power and terminal position information of the wireless node, and then transmits the random access process to the core network. The core network transmits the advanced data to the CPU, the CPU stores the downlink data and extracts the downlink data profile so as to further calculate the power configuration required by different wireless nodes, and transmits the calculated wireless node configuration power to the wireless node, so that the wireless node can configure the power according to the parameters transmitted by the CPU and transmit the configuration completion signaling to the CPU so as to transmit the downlink data.
In the embodiment of the invention, through further strengthening the 6G distributed antenna architecture, different wireless nodes can be integrated into the 6G distributed antenna architecture through the technology of configuring differentiated power from the two angles of uplink triggering and downlink triggering, and the requirements of differentiated power or power self-adaptive joint distributed deployment are realized through the function strengthening of the terminal, the wireless nodes and the CPU, so that the aim of centering on a user is fulfilled. Considering that different power configurations can meet the conditions of different users and have certain interference isolation, the requirements of interference elimination and user demand satisfaction are met by adjusting the transmitting power of different nodes. .
