Patent ID: 8780849

Claim:
A method for dynamic allocation of time-frequency resource blocks of orthogonal frequency division multiple access (OFDMA) frames between a macro cell base station and a set of distributed extension cell base stations within the macro cell based on user-population variance, the method comprising: detecting, by at least one of the macro cell base station or the set of distributed extension cell base stations, that a change in a user-population serviced exceeds a threshold; performing an initial allocation in which the set of extension cell base stations are allocated NF F + M of tiles corresponding to the time-frequency resource blocks, wherein N is the total number of said tiles, F is the total number of extension cell users and M is the total number of macro cell users, and in which the macro cell base station is allocated remaining tiles; varying the number of tiles allocated to said set of extension cell base stations; and iterating said varying until a utility measure for said macro and extension cell base stations is optimized.
