Patent ID: 8509798

Claim:
A resource block allocation method for a cooperative apparatus, the cooperative apparatus being used in a wireless network, the wireless network comprising a plurality of femtocells which include a first femtocell and a second femtocell, the first femtocell recording a first signal interference value between the first femtocell and the second femtocell according to a reference signal received power transmitted by the second femtocell, and the second femtocell recording a second signal interference value between the second femtocell and the first femtocell according to a reference signal received power transmitted by the first femtocell, the resource block allocation method comprising the steps of: (a) enabling the cooperative apparatus to receive the first signal interference value and the second signal interference value from the first femtocell and the second femtocell respectively; (b) enabling the cooperative apparatus to determine that one of the first signal interference value and the second signal interference value exceeds a signal interference threshold; (c) enabling the cooperative apparatus to assign the first femtocell and the second femtocell into a first femtocell group according to a result of the step (b); and (d) enabling the cooperative apparatus to allocate a first resource block to femtocells of the first femtocell group averagely.
