Performance evaluation of network productivity for LTE heterogeneous networks with reward-penalty weights assessment

LTE Femtocells are designed to increase capacity and coverage especially for the indoor and cell-edge mobile users. Typically, they are deployed to offload the macrocell users. However, due to co-location of femtocells in macrocell coverage, the co-tier and cross-tier interferences are high. The interference levels are different for each femtocell access mode. In this paper, we conduct experiment and study the network performance of LTE network with femtocells operating in three access modes. We define network productivity which measures the network performance based on reward associated with new call arrivals and penalty accounted for forced termination due to handoff failure. We conclude with specific parameter setup for reward and penalty weights for each network deployment and determine the desired network performance for each femtocell deployment.
