Abstract:
1. A radio reception apparatus to be used in a radio communication system where communication is performed by using a plurality of resources defined in a frequency-time domain, the radio reception apparatus comprising: a resource information acquiring section which is configured to acquire distribution resource information for a second reference signal when the second reference signal for a second communication system is transmitted from a radio transmission apparatus in addition to transmitting a first reference signal for a first communication system, in a case where distributed type resources in which a resource unit defined in the frequency-time domain is divided in a time direction and distributedly allocated at predetermined frequency intervals are used as resources for the second reference signal; a receiver which is configured to receive a signal containing the second reference signal transmitted from the transmission apparatus; a channel quality measuring section which is configured to measure a channel quality of a transmission channel by using the second reference signal that is allocated in the distributed type resources on the basis of the distribution resource information; and a feedback information transmitter which is configured to transmit feedback information containing channel quality information indicative of the channel quality, to the transmission apparatus.
