Abstract

A transmission device is disclosed that includes a frequency scheduling unit configured to allocate resource blocks as a unit to each user, the resource blocks being blocks of consecutive frequency subcarriers divided from a system bandwidth, constitute a first group including consecutive plural resource blocks, constitute plural second groups, each including one or more resource blocks of the plural resource blocks constituting each first group, and allocate the resource blocks of either the first group or one or more the second groups; a mapping unit configured to allocate transmission data to the resource blocks in accordance with the allocation; and a control information generating unit configured to generate control information with respect to a mobile station to which either the first group or one or more the second groups are allocated.

Dependent claims

A transmission device, comprising:

a frequency scheduling unit adapted for a system where
i) a system bandwidth is divided into a plurality of resource blocks each comprising a plurality of consecutive frequency subcarriers;
ii) first groups, fewer than the resource blocks, are defined to respectively be a group of a plurality of consecutive resource blocks;
and
iii) second groups are defined so that each of the second group is included in each of the first groups and includes at least one resource block included in each of the first groups, the frequency scheduling unit being operative to assign a downlink channel to at least one first group or at least one resource block in the second groups;
and
a mapping unit operative to map data in the downlink channel into the at least one first group assigned by the frequency scheduling unit or the at least one resource block assigned by the frequency scheduling unit.
