Optimization of the number of numerologies and numerology selection method in fifth generation cellular communications systems

Abstract

According to the necessities of users under a service of one base station, the disclosed method decides how many instantaneous numerology structures should be used mostly and selects the most suitable numerologies from the existing numerology set.

Description

TECHNICAL FIELD[0001]The invention relates to the method of selecting the most suitable numerologies from the existing numerology set by determining the number of different numerology structures instantaneously for the mixed numerology structures to be used between the base station and the sim card devices in the 5th Generation (5G) and beyond cellular communication systems.THE STATE OF THE ART / KNOWN STATUS OF YOUR TECHNIQUE[0002]There have been great developments in personal communication technologies in recent years. Some of these may be the increase in demand for applications that require high data rates such as Internet, television, real-time games, and the growing variety of applications that lead to different types of necessities, such as the increasing number of users recently. With the changing system and user requirements, in the last twenty-five years, 2nd Generation systems, 3rd Generation systems and 4th Generation systems were developed in terms of cellular communicatio...

AI Technical Summary

Benefits of technology

The invention is a method for selecting the best numerology structure for each user in a cellular communication system, based on their needs and the flexibility of the system. The method calculates the flexibility of the system using a novel metric called "flexibility value" and selects the most suitable numerology for each user based on their requirements. The method ensures that the system can flexibly adjust the number of numerologies used for each user, while optimizing the overall satisfaction of the system. The invention can be easily implemented by a base station and can be used with existing numerology sets.

Problems solved by technology

In other words, the combination of fewer numerologies reduces the loss of spectral efficiency.

However, in this case, the flexibility of the system cannot be achieved at the desired level.

Apart from the spectral efficiency metric, as the number of numerology structures used simultaneously by a base station increases, the signaling overhead and scheduling complexity on the cellular communication network to which this base station is connected can also increase.
