Patent ID: 8325654

Claim:
A method for managing radio resources in an orthogonal frequency division multiple access (OFDMA) network, said method comprising: periodically determining, by a base station, an optimal power allocation for an access terminal within each sector of a plurality of sectors, said periodically determining comprising: calculating a sector transmission rate corresponding to said each sector, the calculating comprising: detecting a power, p i , of a transmission from said access terminal; computing a channel gain, g ii , within said each sector; detecting a total interference, X i , experienced by said each sector; detecting a background noise, N i , experienced by said each sector; and calculating said sector transmission rate, r i , using a formula: r i = log ⁡ ( 1 + x i X i + N i ) ; and comparing said calculated sector transmission rate to a threshold transmission rate; and changing, by the base station, said optimal power allocation for said access terminal to maximum power when said calculated sector transmission rate is greater than said threshold transmission rate; wherein said periodically determining has an independent start time for each sector and a same period for each sector.
