| Abstract(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 very important issue because it influences the PeNB deployment gain and interference situation. Especially 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 this paper, to avoid this situation, we assume the control information interface between PeNB and MeNB and propose the scheme which enables MeNB to transmit the control information to users serving PeNB in LTE system. We focus on the interface delay between PeNB and MeNB and evaluate the results by using system level simulation. |
