Joint Load Balancing and Admission Control in OFDMA-Based Femtocell Networks

Free registration required

Executive Summary

In this paper, the authors consider the admission control problem for hybrid access in OFDMA-based femtocell networks. They assume that Macrocell User Equipments (MUEs) can establish connections with Femtocell Base Stations (FBSs) to improve their QoSs. Both MUEs and Femtocell User Equipments (FUEs) have minimum rate requirements, which depend on their geographical locations and maybe their running applications. In addition, blocking probability constraints are imposed on each FUE so that connections from MUEs only result in controllable performance degradation for FUEs.
