<p>A signal containing uplink control information is efficiently transmitted and received between a base station apparatus and a mobile station apparatus. A terminal apparatus includes a first reception processing unit and a first control unit. The first reception processing unit receives, from the base station apparatus, information indicating a plurality of second PDCCH areas, each second PDCCH comprising a set of one or more eCCEs, each eCCE comprising a set of a plurality of eREGs, the eREGs comprising resources of a plurality of divisions of a single DL PRB pair, a PUCCH resource corresponding to each eCCE, and information indicating the PUCCH resource at which association with the eCCEs of the second PDCCH area is started for each second PDCCH area. The first control unit sets, for each second PDCCH area, the PUCCH resource at which the association with the eCCEs of the second PDCCH area is started, on the basis of the received information.</p> |
