Abstract

A technology capable of reducing interference of other cells by fully reserving kinds of step sizes to be used for reducing the interference of other cells irrespective of the number of physical resource blocks of distributed transmission. An OFDM mapping method uses a sub block split from or combined with a physical resource block as a shift unit for mapping a symbol of a virtual resource block, thereby fully reserving the kinds of step sizes and setting a different step size for each cell. Effects of reducing the interference of other cells can be expected with this method, and good communication can be realized.
