Abstract:
1. A base station, comprising: a scheduler determining a resource block to assign a data channel for a user apparatus, wherein a plurality of resource blocks each occupying a predefined band and a predefined period are arranged in a frequency axis direction in a system band and each of the resource blocks is assigned to a single user apparatus; and a transmission unit generating a transmission signal for transmitting the data channel assigned to the resource block determined by the scheduler and transmitting the transmission signal to the user apparatus, wherein the scheduler defines a first assignment unit having a predefined size and a second assignment unit having as twice size as the first assignment unit as assignment units of the resource blocks, a plurality of resource blocks having the first assignment unit allowed to assign to a single user apparatus are locally arranged in two consecutive resource blocks in a system band, and resource block groups each consisting of two locally arranged consecutive resource blocks having the first assignment unit are arranged to separate one of the resource block groups from an adjacent one of the resource block group by one resource block having the second assignment unit such that the resource block groups are globally distributed over the system band.
