Abstract:

In this letter, by focusing on α-fairness resource allocation in single channel TDMA system with slow Rayleigh fading, we study the impacts of α on the system efficiency and Jain's index which is widely used as a fairness measure. Also, we prove that increasing α results in higher efficiency but lower Jain's index and reveal the role of α in controlling the tradeoff between efficiency and fairness. Furthermore, an algorithm is proposed to find the optimal α under a system efficiency constraint or a Jain's index constraint with fast convergence and low complexity.

I. Introduction

RESOURCE Allocation in wireless communication systems aims to increase system efficiency and simultaneously improve user fairness. However, these two goals are inversely related as one waxes the other wanes [1]. To deal with this dilemma, many studies focused on maximizing -utility function, which further results in -fairness resource allocation [2]–[5].
