Resource allocation for femtocell networks with imperfect channel knowledge

We propose an efficient resource allocation scheme for OFDMA based femtocells networks under imperfect channel knowledge. Several femtocell users share the same spectrum but no interference exists between each other. The transmit power of femtocell users is minimized under the users' QoS constr...

description	We propose an efficient resource allocation scheme for OFDMA based femtocells networks under imperfect channel knowledge. Several femtocell users share the same spectrum but no interference exists between each other. The transmit power of femtocell users is minimized under the users' QoS constraints. Based on the interference channel model of femtocell users, an accurate interference estimation approach is developed. Simulation results show that the proposed algorithm reduces the interference of macro users and increases the spectral efficiency.
