Abstract :
Femtocells can offload the traffic of macrocells and satisfy the big high-data-rate wireless communication requirement of indoor users. Due to the large number of femtocells deployed by users, a significant challenge this new access technology brings to us is coordinating the cross-tier interference. Much special attention has been paid to solve the problem. This paper presents a novel strategy to configure femtocell users´ power and bandwidth jointly and an algorithm to estimate the connection QoS requirement. The strategy can effectively reduce the cross-tier interference while ensuring high spectrum efficiency. Also simulations are given to show the effect of the strategy.
