  Abstract

In this letter, we propose a multi-cell pseudorandom beamforming (PRBF) technique based on multiple eamforming matrix selection for multi-cell downlink networks. We assume that each base station(BS) is synchronized in time and each user is assumed to know multiple pseudo-random beamforming matrices of BSs. Each user feeds back the SINR of beamforming matrices and the corresponding BS the optimal users who result in the maximum sum-rate for each beamforming matrix. Then, each BS sends the achievable sum-rates for M beamforming matrices to BS coordinator via wired backhaul link. The BS coordinator sends back the index of the beamforming matrix maximizing the total sum-rate of the total network to BSs. The proposed PRBF technique outperforms the conventional technique in terms of sum-rate.
