(A09) MOU Contract with G. Fettweis’ group (Vodafone Chair Mobile Communications Systems) @ TU Dresden as of Aug. 2016.
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
[P07] APPARATUS AND METHOD FOR CONTROLLING INTERFERENCE BETWEEN SMALL-CELL BASE STATIONS BY USING MULTI-ANTENNA BEAMFORMING, Co-invented with ETRI (KR 10-2015-0162153, US 15/355,602).
[C21] M. U. Kim, Y. Kim, Y. Cho, and H. J. Yang, “Downlink beamforming in small cells with scalar information exchange,” in Proc. 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
