Abstract (in Japanese) (See Japanese page) 
(in English) This paper investigates a multi-access technique for Long Term Evolution (LTE)-Advanced, which is a candidate radio interface for IMT-Advanced in the 3rd Generation Partnership Project (3GPP). First, we discuss the radio interface design to support a transmission bandwidth wider than that in Release 8 LTE (Rel-8 LTE). There are two major approaches. The first is a parallel transmission scheme for Rel-8 LTE. The other is the proposed concept for a layered transmission scheme that provides a radio interface that is more optimized to support a wider transmission bandwidth in LTE-Advanced. In the 3GPP, however, a parallel transmission scheme was adopted due to its simplicity because it reuses the Rel-8 LTE functionalities as much as possible. Thus, we also need to investigate alternative techniques to satisfy the high performance requirements in LTE-Advanced. In this paper, we show that coordinated multipoint transmission and reception (CoMP) is effective in improving the cell-edge user spectral efficiency and that enhancing of multi-antenna techniques including space division multiple access (SDMA) is key to achieving the high capacity requirement in LTE-Advanced.
