A two-stage downlink beamforming design is proposed for multicell multi-input single-output channels with limited backhaul capacity and local channel state information (CSI). The first stage is to maximize the signal-toleakage-plus-noise ratio with local CSI. Each base station (BS) then calculates the corresponding channel gains and shares them with all other BSs, which typically requires low-rate… Continue reading

International Conference on ICT Convergence (ICTC), Busan, Korea, Oct. 2014, pp. 446-449. Abstract Multi-input single-output (MISO) beamforming techniques are addressed in the downlink small cells environment, where a small cell base station (BS) has multiple antennas… Continue reading
