Abstract
A terminal apparatus includes a reception unit that receives first information indicating a subframe in which a CRS is present, and second information which indicates the number of CRS antenna ports and is used to determine a resource element to which a PDSCH is mapped. In a subframe other than a subframe indicated as the subframe in which the CRS is present by the first information, a resource element to which a PDSCH transmitted through an antenna port different from a CRS antenna port for a serving cell is mapped is based on the number of CRS antenna ports indicated by the second information corresponding to the PDSCH. Accordingly, the terminal apparatus can efficiently communicate with a base station apparatus using a downlink physical channel.
