Abstract
A base station device includes a determining unit that determines a combination of a plurality of users having different reception qualities, an allocating unit that generates a plurality of hierarchical modulation channels having different qualities based on channel elements constituting channels corresponding to the respective users in the combination determined by the determining unit, and allocates the hierarchical modulation channels to the respective users such that a hierarchical modulation channel having a higher quality is allocated to a user having a lower reception quality, a mapping unit that maps data for each user to the hierarchical modulation channel allocated to each user by the allocating unit, and a transmitting unit that transmits the data mapped by the mapping unit.
