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

Yang*, “Opportunistic network decoupling with virtual full-duplex operation in multi-source interfering relay networks,” IEEE Transactions on Mobile Computing, vol. 16, no. 8, pp. 2321 – 2333, August 2017. Abstract We introduce a new achievability scheme, termed opportunistic network decoupling (OND), operating in virtual full-duplex mode. In the scheme, a novel… Continue reading
