| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we investigate user allocation scheme to support coordinated multi-point (CoMP) operation for Long-Term Evolution (LTE)-Advanced systems studied in the 3rd Generation Partnership Project (3GPP). CoMP, which improves cooperative transmission among network nodes (transmission points: TPs) and reduces or eliminates inter-TP interference, enables performance improvement mainly in cell edge throughputs. We employ dynamic point selection with blanking as CoMP scheme, which requires both a) efficient CSI reporting scheme to avoid additional CSI reporting overhead and b) further analysis of Proportional Fairness (PF) metric calculation with maintaining PF criteria. To this end, we propose i) to use CSI estimation assumption which can be applicable for with or without blanking and ii) to apply weighting factor in accordance with resources blanking is applied. To evaluate the benefits of this algorithm, multi-cell system level simulations accounting channel estimation error are carried out. This confirms improved algorithm enables to maintain fairness and to achieve excellent performance for dynamic point selection with blanking. | |
