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.

The main objective is to protect mobile users located near the cell boundary from detrimental downlink interference originating from neighboring base stations (BSs) without compromising the system spectral efficiency. For this purpose, a novel autonomous resource assignment method that is

The main objective is to protect user equipments (UEs) that are located near the cell boundary of two or more femtocells from detrimental downlink interference. The available frequency bands are divided into subbands that are distributed among femtocells in a way that directly adjacent cells do not

User- deployed femto-cells, each exclusively serving a set of registered users and sharing the same frequency spectrum as the overlay macro-cells are already defined in
