| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | 3D cell structure is effective to cope with rapidly increasing mobile data traffic, in which small cells are three-dimensionally overlaid on outdoor macro cells including vertical direction. In order to increase spectral efficiency further in this 3D cell structure, it is necessary to reduce interference beween outdoor macro cells and small cells. eICIC (enhanced Inter-Cell Interference Coordination) is one of the key technologies of LTE-Advanced. This technology reduces inter-cell interference by applying ABS (Almost Blank Subframe), with which data channel (PDSCH) transmission is stopped. The interference on PDSCH can be avoided by using ABS. However, the interference on control channel (PDCCH) remains because PDCCH can be transmitted even though ABS is applied. Informations of resource allocation, modulation and coding rate are transmitted on PDCCH and essential to decode PDSCH. Therefore, the performance degradation in PDCCH results in throughput degradation by not being able to decode PDSCH. In this paper, we propose an interference control technique for PDCCH, which controls PDCCH allocation region, and we evaluate the proposed method by numerical calculation and experiment. | |
