Terminal receiving resource block allocation and method therefor

摘要

In a wireless communication base station device, a modulation unit carries out modulation processing for Dch data after coding to generate a Dch data symbol. A modulation unit carries out modulation processing for Lch data after coding to generate an Lch data symbol. An allocation unit allocates the Dch data symbol and Lch data symbol to each sub-carrier composing an OFDM symbol and outputs the allocated sub-carrier to a multiplex unit. In this case, the allocation unit allocates the Dch data symbol to a plurality of resource blocks where one Dch is arranged at an interval equal to integral multiples of the number of resource blocks composing a resource block group.

1. A terminal, comprising,
a receiver, which, in operation, receives assignment information indicating resource blocks, each of which is comprised of consecutive subcarriers in a frequency domain, allocated to the terminal in one of a plurality of resource allocations including:
a resource allocation allocating Distributed Virtual Resource Blocks (DVRBs), a pair of DVRBs assigned by a single resource block number being mapped to Physical Resource Blocks (PRBs) with a gap in a frequency domain, the gap being an integer multiple of a Resource Block Group (RBG) size defined as a number of one or more consecutive PRBs comprising one RBG, the gap and the RBG size being associated with a system bandwidth; anda resource allocation allocating one or more RBGs; and circuitry, which, in operation, decodes data based on the assignment information.
