Wireless communication apparatus and frequency hopping method
First Claim
1. An integrated circuit to control a process performed at a terminal apparatus configured with a plurality of downlink component carriers, the process comprising:
- receiving downlink control information for each of the plurality of downlink component carriers; and
transmitting a signal on a frequency resource, the frequency resource including a first frequency resource and a second frequency resource of an uplink channel and being determined from resource information included in the downlink control information, with a frequency hopping between the first frequency resource in a first slot and the second frequency resource in a second slot within a subframe,wherein a frequency hopping interval between the first frequency resource and the second frequency resource that are determined from the resource information included in the downlink control information for one of the plurality of downlink component carriers is the same as that for another one of the plurality of downlink component carriers.

Abstract
Disclosed are a wireless communication apparatus and frequency hopping method which minimize the change in the instantaneous power distribution characteristics of the time waveform of transmission signals when a plurality of channels are multiplexed by frequency division. At a terminal (200), a mapping unit (212) maps the PUCCH to frequency resources of a first slot, maps the PUSCH to frequency resources, among the frequency resources of the first slot, separated exactly by predetermined frequency spacing (B) from the frequency resources to which the PUCCH is mapped, and cyclically shifts the frequencies so as to map the PUCCH and PUSCH to frequency resources, within an IDFT or IFFT bandwidth, of a second slot while maintaining the predetermined frequency spacing (B), thereby allowing frequency hopping of the PUCCH and PUSCH between the first slot and the second slot.
