RADIO BASE STATION AND RADIO COMMUNICATION METHOD
First Claim
1. A radio base station apparatus used in a radio communication system in which a plurality of resource blocks consisting of a system band are grouped into a plurality of resource block groups for every P resource blocks and a second band is divided into a plurality of subbands, the second band being other than a first band to which control channels assigned at both ends of the system band can be assigned, the radio base station apparatus comprising:
- an assignment section that assigns the plurality of resource blocks to a terminal apparatus assigned a non-continuous band in units of the resource block groups; and
an extraction section that extracts a data signal frequency-hopped for every plurality of subbands by a frequency hopping terminal apparatus, from the plurality of resource blocks in the second band, whereineach bandwidth of the plurality of subbands is a natural number multiple of P.

Abstract
Disclosed is a base station capable of minimizing in Type 0 assignment the number of resource block groups occupied by a terminal that performs frequency hopping, and thereby flexibly assigning resources in the Type 0 assignment. The base station (100) is used in a radio communication system in which a plurality of resource blocks constituting the system band thereof are grouped into resource block groups each consisting of P resource blocks, and the band that is not a PUCCH-assignable band to which PUCCHs assigned to both ends of the system band can be assigned is divided into a plurality of sub-bands. The base station (100) comprises an assignment unit (1102) and a demapping unit (112). The assignment unit (1102) assigns a plurality of resource blocks in units of resource block groups to terminal apparatuses to be subjected to noncontiguous-band assignment. The demapping unit (112) extracts, from a plurality of resource blocks in a second band, data signals for which frequencies are hopped by a frequency-hopping terminal apparatus from one to another of the plurality of sub-bands. Here, the bandwidth of each of the plurality of sub-bands is a natural-number multiple of P.
