Abstract (in Japanese) (See Japanese page) 
(in English) Relaying is a key technology used to improve cell-edge user throughput and/or provide wider coverage. Three-dimensional (3D) beamforming, which operates in both azimuth and elevation antenna domains, is a key technique to increase the signal-to-interference plus noise ratio (SINR) of a receiver. Based on these technologies, this paper proposes the application of 3D beamforming to a backhaul link in time-division relaying. We investigate the 3D beamforming effect in comparison to conventional backhaul link. Average and 5-percentile user throughput are described as parameters of almost blank subframe (ABS) ratio in time-division relaying using system-level simulation. Furthermore, we also evaluate the user throughput as parameters of the distance between an eNB and the related RN, the number of RNs per sector, and the transmission power of RN.
