Abstract (in Japanese) (See Japanese page) 
(in English) In Heterogeneous Network (HetNet) where low power nodes (Pico eNodeBs: PeNB) are placed into a macro-cell system, serving cell selection scheme is one of important issues because it influences the PeNB deployment gain and interference situation. Especially in uplink, it is known that the pathloss (PL) based serving cell selection scheme can provide significant gain. In our recent paper, however, the view point of downlink control information (PDCCH), we showed the PL scheme is degreased by PDCCH error because of interference from Macro eNBs (MeNB), which has higher Tx Power than PeNB. In order to avoid this situation, we studied the scheme which enables MeNB to transmit the control information to users served by PeNB assuming the control information interface between PeNB and MeNB in LTE system and we showed its effectiveness. On the other hand, it is predicted that this PDCCH transmission scheme is highly influenced by fast fading because of the large delay between scheduling and resource allocation. We focus on the influence of fast fading and evaluate the results by using system level simulation.
