FIELD: physics, communications.SUBSTANCE: invention relates to a base station device and a communication method used for multi-carrier communication. The station device includes: a selection unit for selecting a mobile station resource block using one of a first selection and a second selection, wherein the resource blocks, each comprising a plurality of subcarriers, are sequential in the frequency domain, are divided into a plurality of groups, each comprising a predefined number of resource blocks which are sequential in the frequency domain; and a transmitting unit for transmitting to the mobile station control information which includes both information of the difference between the first selection and the second selection and information indicating the selected resource block, where in the first selection said plurality of groups is divided into a plurality of sets which includes a first set comprising at least two groups which are part of said plurality of groups and are non-sequential in the frequency domain, and a second set comprising at least two groups which are different from said part of said plurality of groups and are non-sequential in the frequency domain.EFFECT: preventing increase in overhead of allocation result report in frequency scheduling in a multi-carrier communication system.22 cl, 17 dwg |
