Abstract

The present invention disclosed a method of optimizing the number of 5G communication system terminals in the dense scenario. The terminals in the system include the honeycomb network terminal (CUE) and the D2D mobile terminal (DUE).The communication radius, path loss factors in the community, etc. (2) Initialize the color matrix of the resource allocation scheme according to the number of CUE and D2D users in the network;Later Due's signal interference noise ratio to determine the selected color order; (4) determine whether the new DUE meets the requirements of the access network, if not satisfied, select the next D2D pair, transfer to step (3); (5)For newly accessing DUE coloring groups; (6) After all Due packets are completed, the end method is ended.The present invention can achieve the resource optimization and distribution of 5G communication systems, calculate the maximum number of connecting D2D terminals in the system, and effectively increase the number of D2D users in the system.

Description

technical field [0001] The invention relates to the field of 5G communication, in particular to a method for optimizing the number of terminals connected to a 5G communication system in a dense scene. Background technique [0002] With the rapid development of mobile communication technology, today's social development is more information-based and intelligent. Among them, in the field of wireless communication, 5G communication technology is also more mature. Due to the increasing demand of users for voice and data services, wireless communication networks need to continuously adopt new technologies to improve frequency utilization and improve network throughput. The traditional wireless cellular network requires base station transfer during communication, and the resource utilization efficiency is low. As a key technology of 5G, end-to-end communication (D2D) can effectively improve the resource utilization of the cellular network, which allows adjacent terminal devices to...
