Abstract   User association and resource allocation for downlink orthogonal frequency division multiplexing are jointly optimized in small cells networks with limited backhaul. In particular, per resource block resource allocation under the backhaul constraint is formulated in pursuit of maximizing proportional fairness, which leads to an integer problem requiring prohibitive computational complexity to solve. We… Continue reading

Oh, “Sum-rates of asynchronous GFDMA and SC-FDMA for 5G uplink,”  ICT Express, vol. 1, no. 3, pp.127-131, Dec. 2015 Abstract The fifth generation (5G) mobile envisions ultra-low latency less than 1ms for end-to-end communications. To this end, frameless asynchronous multiple-access may be needed to allow users to… Continue reading

International Conference on ICT Convergence (ICTC), Busan, Korea, Oct. 2014, pp. 936-940. Abstract Two-way relaying has been known to double the spectral efficiency of the one-way relaying scheme in a single cell system. In this paper, we observe… Continue reading
