Distributed and autonomous resource allocation for femto-cellular networks

A distributed and autonomous technique for resource and power allocation in femto-cell networks is presented. Resource blocks (RBs) are assigned to the user(s) in each cell individually without coordination between base stations (BSs). The allocatability of each resource is determined using only local information: · the user´s required rate; · the quality of the desired signal; · the level of interference incident on each RB; and · the frequency-selective fading on each RB. Using fuzzy logic, these inputs are combined to determine which RBs are most suitable for allocation in a particular cell. A comprehensive study of this system yields a staggering system performance improvement over state-of-the-art interference coordination techniques.
