Abstract

To realize extremely high data rate of 50M-1Gbps in the 4G era, innovative circuit technologies for wider bandwidth and higher spectrum efficiency are required. In addition, some technical problems arise from increasing network density. For these technical challenges, we are developing the system technologies of inter-cell interference coordination and flexible mobile backhaul, and the circuit technologies of carrier-aggregation transmitters, highly efficient digital transmitters, and high-speed signal processing; these technologies enable to reduce operator´s Total Cost of Ownership (TCO).
