Abstract

A non-orthogonal access downlink 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 downlink transmission time of the base station and the total energy consumption of the base station when the download amount of the mobile user is given; among them, the optimization problem is described as a non-convex optimization problem; (2) the DDRCM problem is equivalently transformed into DDRCM‑ E problem, the DDRCM‑E problem is equivalently transformed into a P1 problem; (3) In order to judge whether the P1 problem is feasible under the given value of θ, a P2 problem is proposed; based on the binary search method, when the download volume of mobile users is given Optimize downlink resource consumption (downlink transmission time and total energy consumption of the base station) in the case of . The invention minimizes the downlink transmission time and the total energy consumption of the base station.

Description

technical field [0001] The invention belongs to the communication field, and relates to a non-orthogonal access downlink transmission time optimization method based on a binary search formula. 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, using 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. Contents of the invention [0003] In order to overcome the shortcomings of the prior art that the downlink transmission time is long and the total energy consumption of the base station is large, the present invention provides a non-orthogonal access downlink transmission based on a binary search method that minimizes the downlink transmission time and the t...
