Abstract
The 5G mobile networks is a New Radio for finding wireless access solutions for Internet access of users with the most demanding requirements for quality service. To implement it radio interface resource allocation functions implemented by hardware and software vendors at base stations must notify subscribers about their decisions with so-called control channels the functions of which are distributed in the CORESET configuration area. The settings of the CORESET parameters affect the efficiency of using radio channel resources. This article discusses CORESET issues and their impact on the efficiency of using radio resources.
