Non-orthogonal access downlink transmission time optimization method based on depth deterministic policy gradient

Abstract

A non-orthogonal access downlink transmission time optimization method based on a depth deterministic policy gradient includes the following steps: (1) in the case that a total of I mobile users existin the coverage range of a base station, proposing a service quality that satisfies the mobile users, and minimizing the downlink transmission time of the base station and the total energy consumption of the base station in the case that the download amount formula (as shown in the original specification) of the mobile users is specified; (2) ensuring that a DDRCM problem is to find the optimal downlink resource consumption in the case that the download amount formula (as shown in the original specification) of the mobile users is specified, and observing the DDRCM problem to know that an objective function of the problem has only one variable t; (3) finding an optimal downlink transmission time t* through a depth deterministic policy method to ensure that the optimal downlink resource consumption (the downlink transmission time and the total energy consumption of the base station) exists; and (4) continuously repeating the iteration process until the optimal downlink transmission time t* is obtained, and further ensuring that the optimal downlink resource consumption exists. According to the scheme of the invention, the downlink transmission time and the total energy consumptionof the base station can be minimized.
