Adaptive Radio Resource Allocation Framework for Multi-User OFDM

Free registration required

Executive Summary

Spectral efficiency, fairness and user satisfaction are crucial aspects for resource allocation in multi-user Orthogonal Frequency Division Multiplexing (OFDM)-based cellular networks. Classical Radio Resource Allocation (RRA) strategies, such as Max-Rate (MR), Proportional Fairness (PF) and Max-Min Fairness (MMF), show different performances regarding the three aforementioned aspects. In this paper, the authors present an adaptive RRA framework that joins the criteria of the three classical strategies in a unified manner and can be dynamically configured according to the cellular operator's objectives.
