Jointly optimized interference aware coordinated beamforming (IA-CBF) algorithms for a two-cell system are investigated, where each base/mobile station is equipped with multiple transmit antennas. We first derive a minimum-mean-square-error IA-CBF algorithm based on a lower bound on the achievable sum rate. We next propose optimal (under an assumption of zero other-cell interference) and suboptimal transmit/receive beamforming vectors through zero-forcing IA-CBF algorithms. Numerical results confirm that the proposed system shows better sum rate performance than competitive solutions such as non-cooperative eigen-beamforming and interference nulling.
