Abstract
The present disclosure provides a coordinated multiple access method for multi-cell ground-to-air data transmission, and belongs to the technical field of wireless communication. The method comprises the following steps: S, constructing a model of a coordinated multiple access system for multi-cell ground-to-air data transmission; S, calculating a transmission rate of an aircraft, and constructing a multi-cell airspace and power domain resource allocation optimization problem by taking maximizing a system transmission rate as an optimization objective; S, constructing a Markov decision process model; S, solving the optimization problem using a multi-agent deep reinforcement learning algorithm. The system transmission rate is maximized under the condition that the aircraft can decode the signal correctly and satisfy the constraint of minimum transmission rate, thereby realizing ground-to-air high-speed data transmission. The present disclosure adopts the coordinated multiple access method for multi-cell ground-to-air data transmission, which can realize fast online decision, satisfying the requirements of ground-to-air high-speed data transmission in the high dynamic flight scenario of the aircraft.
