A Linear Search Based Uplink Transmission Time Optimization Method for Non-Orthogonal Access

Abstract

A non-orthogonal access uplink transmission time optimization method based on a linear search formula, comprising the following steps: (1) there are 1 mobile users in total under the coverage of the base station, and a quality of service that satisfies the mobile users is proposed, Minimize the uplink transmission time of mobile users and the total energy consumption of all mobile users. Among them, the optimization problem is described as a non-convex optimization problem; (2) The ORRCM problem is equivalently transformed into the ORRCM-E problem, and the ORRCM-E problem is equivalently transformed into the D1 problem; (3) The algorithm ORRCM-E for solving the D1 problem Algorithm, in order to judge whether the D1 problem is feasible under the given value of θ, the D2 problem is proposed; based on the linear search method, the overall wireless resource consumption is optimized when the upload volume of mobile users is given. The present invention minimizes uplink transmission time and total energy consumption of all mobile users.
