Quality of Service Class Identifier (QCI) radio resource allocation algorithm for LTE downlink

Area of Science:

• Telecommunications Engineering
• Computer Networks
• Wireless Communication

Background:

• The Third Generation Partnership Project (3GPP) introduced Long Term Evolution (LTE) to meet diverse network application demands.
• LTE networks utilize resource allocation algorithms to manage radio resources for user bandwidth and delay requirements.
• Existing LTE resource allocation algorithms face performance degradation, particularly under prioritized conditions, due to limitations in scheduling and minimum data rate determination.
