Abstract

In this paper, we analyze the behavior of several radio resource scheduling strategies under different power and subcarrier allocation (PSA) and inter-cell interference (ICI) coordination schemes in mobile OFDMA networks. The aim is to test the capability of these scheduling strategies to deal with quality of service (QoS) requirements both in a single-service scenario or when a mixture of services takes place. This work shows that radio resource allocation schemes managing ICI have strong impact on the scheduling policy behavior, and that traffic delay is a key parameter to track in order to provide QoS when services with different delay constraints simultaneously occur.
