    摘要： A radio terminal, radio base station, channel signal forming method and channel signal receiving method wherein when an upstream unit band and a plurality of downstream unit bands associated therewith are used to perform communications, the quality of downstream assignment control information can be prevented from being degraded. In a base station (100), the PDCCH signals including upstream assignment control information are limited to ones that are placed in some of the downstream unit bands. This can reduce the probability of performance of zero padding to downstream assignment control information having greater importance. Also in the base station (100), the PDCCH signals of the downstream unit bands other than the basic unit band include only downstream resource assignment information. For this reason, in the individual regions of the downstream unit bands other than the basic unit band, the bandwidth of the downstream unit bands is always used as a reference of size adjustment and hence requires no information size adjustment. As a result, there is no need of performing zero padding to the downstream assignment control information, so that the quality of downstream assignment control information can be prevented from being degraded.

    摘要： In a case where a second reference signal for a second communication system is transmitted in addition to a first reference signal for a first communication system, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS, DVRB resources in which a resource unit defined in a frequency-time domain is divided in a time direction and distributedly allocated at predetermined frequency intervals are used and CSI-RS is allocated in a resource ID of a part of DVRB resources and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in DVRM resources on the basis of DVRB setting information for CSI-RS, measures channel quality such as CQI, PMI or RI by using CSI-RS, and transmits and reports feedback information containing channel quality information to a transmission apparatus.

    摘要： This invention relates to a terminal apparatus that can possibly reduce situations in which upstream channel data are punctured by a plurality of response signals. When having received at least one piece of downstream allocation control information corresponding to a second downstream unit band, which is other than a first downstream unit band, of a plurality of unit bands, a control unit (208) maps a plurality of response signals, which are corresponding to the respective ones of the plurality of downstream unit bands established, to a first resource corresponding to the plurality of downstream unit bands established. When having received only the downstream allocation control information corresponding to the first downstream unit band of the plurality of unit bands established, the control unit (208) maps the response signal, which is corresponding to the first downstream unit band, to a second resource corresponding to the first downstream unit band.
