Load-balancing based on Base-Station CoMP with guaranteed call blocking rate

Abstract

As a major part of wireless network optimization, load balancing can make the BS's resource utilization more reasonable. This paper proposes a load-balancing strategy based on Coordinated Multiple Points (CoMP) transmission/reception among the Base Stations (BS). To use universally, different patterns of load-balancing based on CoMP are modeled and discussed. We define call blocking rate as the QoS metric to be guaranteed during load balancing process. The capacity of load-balancing and call blocking rate with different load-balancing patterns based on CoMP are evaluated and analyzed in an area with a moderate dense distribution of high-loaded BSs. The analysis on the numerical results give the proper load balancing pattern based on CoMP with guaranteed call blocking rate.
