Dynamic power allocation method and apparatus for controlling inter-cell interference in multi-cell orthogonal frequency division multiplexing access system

The present invention is a multi-cell OFDMA (Orthogonal Frequency Division Multiplexing Access: OFDMA) channel in the system the terminal receives dynamically allocating power to the inter-cell interference control is configured with different frequency resources to the signal received from the base station to each channel interference amount measurement on, and the channel interference amount measured for each of the channels based on is greater than an interference threshold: determining a channel preference value for each of the channels, said determined for each of the channels generating a channel preference information including the channel preference value, and feeding back the channel preference information to the base station, said base station allocates the power according to the channel preference information is fed back to the BS from the other terminal in the channel preference information, and cell When performing, with the assigned power It receives data from the base station via the channel. OFDMA, multiple cells, the interference cancellation, the power allocation
