Abstract: A reflection unit of a relay apparatus includes a plurality of reflection elements capable of applying independent phase shifts to an incoming wave from a transmission point. The reflection unit estimates a distance between the relay apparatus and a reception point based on terminal information transmitted from the reception point. The number of divisions for grouping the plurality of reflection elements is determined based on the distance. The plurality of reflection elements are grouped into one or more reflection element groups according to the division number. The position of the reception point is estimated based on the terminal information. Each of the reflection element is applied a phase weight so that each of the reflection element groups generates a beam toward the position of a reception point.
