Access Control for Coordinated Multi-antenna Cellular Architecture with Scheduling

While current research focuses on Enhanced 3 Generation and IMT-Advanced mobile systems, many advanced techniques are investigated by world-wide research institutes and standard organization, such as Multi-Input Multi-Output, Coordinated Multi-Point and coordinated multi-antenna cellular network architecture. Based on these novel techniques, the access control strategies also need to be developed. Based on Maximum Utility Principle Access Control method, improved access control algorithm with combination of scheduling for coordinated multi-antenna cellular architectures is proposed in this paper. Two algorithms are brought out with the Proportional Fairness and Maximum C/I utility function respectively. By application in Coordinated Multi-Point based Group Cell architecture, performance evaluation and analyses verify the merits of two proposed algorithms in improving system throughput, user fairness and efficiency of system resources usage.
