Abstract

This paper considers interference mitigation in multicell scenarios where transmitters and receivers are both equipped with multiple antennas. In multicell system, both the local Pre-coding Matrix Index (PMI) and the interference PMI can be utilized by Interference Reject Combing (IRC) algorithm, and more interference information can be obtained from the enhanced interference PMI notification. The IRC interference mitigation algorithm can deal with both noise and interference. The specific formulas of calculating receiver weight vector (matrix) based on different criterions are given. And the IRC-adaptive algorithm is proposed, which can have a compromise effect between the complexity and interference mitigation. It is shown in the simulation results that the receiver algorithms can improve the system performance effectively.
