An algorithm for joint power and rate allocation is proposed to equalize the downlink quality between cells when there exists traffic non-uniformity. Unlike locally SIR-based power control, the global power allocation to keep the SIR constant across cells is performed by an effective three-cell model per sector of 60 degrees. It is shown that the proposed algorithm increases the average-rate capacity further compared to that with uniform traffic.
