A non-orthogonal access downlink transmission time optimization method based on deep deterministic policy gradient

Abstract

A non-orthogonal access downlink transmission time optimization method based on deep deterministic policy gradients, comprising the following steps: (1) There are a total of I mobile users under the coverage of the base station, and a quality of service that satisfies the mobile users is proposed At the same time, the downlink transmission time of the base station and the total energy consumption of the base station are minimized when the download amount of the mobile user is given; (2) the DDRCM problem is to find the optimal downlink resource consumption when the download amount of the mobile user is given, Observe the DDRCM problem and know that its objective function has only one variable t; (3) Find an optimal downlink transmission time t through a deep deterministic strategy method * , so that there is an optimal downlink resource consumption (downlink transmission time and total energy consumption of the base station); (4) Repeat the iterative process until the optimal downlink transmission time t is obtained * , so that there is optimal downlink resource consumption. The invention minimizes the downlink transmission time and the total energy consumption of the base station.
