This paper proposes a limited quantization feedback mechanism based on error revising according to the characteristics of base-station coordination system. In this mechanism, the channel quantization process is divided into many steps. The number of the steps equals the number of coordinating base stations. Each quantization step corrects the errors in the previous step. From the complexity analysis and system simulations, it is concluded that the new mechanism reduces quantization complexity with very small degradation in the performance as compared to the existing global feedback mechanisms. It improves the system performance with very little increase in complexity as compared to the existing individual feedback mechanisms. The proposed mechanism provides a good tradeoff between complexity and system performance.
