A method for optimizing uplink transmission time of non-orthogonal access based on binary search

Abstract

A non-orthogonal access uplink transmission time optimization method based on a binary search formula, comprising the following steps: (1) There are 1 mobile users in total under the coverage of the base station, and a method that satisfies the quality of service of the mobile users and simultaneously , to 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; (3) the ORRCM‑E problem is equivalently transformed into a D1 problem; Whether the D1 problem is feasible under the conditions, and the D2 problem is proposed; based on the binary search method, the overall wireless resource consumption (uplink transmission time and total energy consumption of all mobile users) is optimized when the upload amount of mobile users is given. The present invention minimizes uplink transmission time and total energy consumption of all users. The technical effects of the present invention are mainly manifested in: 1. For the overall uplink, the use of non-orthogonal access technology greatly improves the system transmission efficiency; 2. For the overall uplink, the use of non-orthogonal access technology greatly saves bandwidth resources ; 3. For mobile users, better wireless network experience quality can be obtained through non-orthogonal access technology.
