Abstract
When communication is performed using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band, the quality of the downlink resource allocation information is reduced by reducing the frequency of the zero information addition processing to the downlink resource allocation information. Radio terminal apparatus, radio base station apparatus, and channel signal forming method capable of preventing deterioration. In a base station (100) capable of communicating using an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band, a plurality of channel signals formed by the PDCCH generation unit (102) for each downlink unit band The uplink unit band uplink allocation information is included in only a part of them, and the padding section (103) is the partial channel signal, and the bandwidth of the corresponding downlink unit band is the bandwidth of the uplink unit band Only in a narrower channel signal, zero information is added to downlink allocation information until the size of the downlink allocation information becomes equal to the size of uplink allocation information.
