摘要：A method optimizes a performance of a multi-cell orthogonal frequency-division multiple access (OFDMA) network that includes a set of base stations (BSs)located in a cell, and each BS transmits data on downlink channels to a set of mobile
stations (MSs) in the cell. Each BS acquires channel state information (CSI) and inter-cell interference information (ICI) for each downlink channel to each MS in the cell. Each BS selects a power level and a modulation coding scheme level (MCS) for transmitting the data to each MS on the downlink channels based on the CSI and ICI, such that a bit rate is maximized and the ICI is minimized. Then, time and frequency resource are allocated for transmitting the data on the downlink channels to the set of MSs, such that the allocated resources are minimized to optimize the performance of the network.
