A carbon-neutral precoding method for wireless coordinated multi-point transmission system

Abstract

The invention proposes a carbon-neutral precoding method oriented to a wireless coordinated multi-point transmission system, which belongs to the technical field of wireless communication network signal processing, and serves multiple users with a base station composed of an access point base station and a central baseband signal processing node Based on the idea of ​​carbon neutrality, considering the use of green energy and traditional grid energy by access point base stations, based on dual variables and cumulative power price information, an effective cumulative power price is constructed, and then the first optimization The model solves the effective precoding matrix, thereby updating the effective cumulative electricity price, and obtains the final precoding matrix; the second optimization model constructed solves the virtual precoding matrix, thereby updating the dual variables, and combines statistical machine learning methods as a whole, repeats the updating steps, and performs the following steps The solution of the user's precoding matrix at one moment makes full use of the historical information of wireless channel parameters and the historical information of accumulated electricity prices to achieve the long-term zero grid energy consumption of the system.

Description

technical field [0001] The present invention relates to the technical field of wireless communication network signal processing, and more particularly, to a carbon-neutral precoding method for a wireless cooperative multi-point transmission system. Background technique [0002] Currently, wireless systems are experiencing a surge in the amount of mobile data, usually from smart terminals (eg, smartphones, tablets, etc.) and IoT devices (eg, sensors, wearable devices, etc.) The amount of mobile data enables operators to continuously upgrade the existing radio access network to a cloud radio access network, thereby improving the wireless system's carrying capacity for the current continuously growing mobile data volume. Under this trend, wireless cooperative multi-point transmission systems emerge as the times require. [0003] The wireless cooperative multi-point transmission system is a wireless communication system composed of multiple access point base stations and a cent...
