Abstract

A non-orthogonal access uplink transmission time optimization method, comprising the following steps: (1) there are 1 mobile users in total under the coverage of the base station, a kind of QoS that satisfies the mobile users is proposed, while the mobile users upload The problem of minimizing the uplink transmission time of mobile users and the total energy consumption of all mobile users when the amount is given; (2) ORRCM problem is to find the optimal overall wireless resource consumption under the given amount of upload by mobile users; ( 3) Find an optimal uplink transmission time t through a deep deterministic strategy method * , so that there is an optimal overall wireless resource consumption; (4) Repeat the iterative process until the optimal uplink transmission time t is obtained * , so that there is an optimal overall radio resource consumption. The present invention minimizes uplink transmission time and total energy consumption of all mobile users.

Description

technical field [0001] The invention belongs to the communication field, and relates to a non-orthogonal access uplink transmission time optimization method based on deep deterministic strategy gradients. Background technique [0002] The rapid development of mobile Internet services has caused enormous traffic pressure on the cellular wireless access network. Due to limited wireless resources, the use of non-orthogonal access technology to allow mobile users to share the same channel at the same time provides an effective method for wireless access to achieve ultra-high throughput and large-scale connections in the future 5G network. We aim to optimize the uplink transmission time of non-orthogonal access based on deep deterministic policy gradient when mobile users send their respective data to the base station. Contents of the invention [0003] In order to overcome the disadvantages of long uplink transmission time and large total energy consumption of all mobile user...
