The purpose of the present invention is to allow a base station device and a terminal device to efficiently communicate using a PDSCH. The base station and the terminal device, on the basis of a transmission mode related to transmission by way of the PDSCH, a DCI format used in assignment of the PDSCH, an antenna port used in PDSCH transmission, and a parameter of a higher layer determined on the basis of a parameter set for a serving cell where the PDSCH is received, determine a starting position for OFDM symbols for the PDSCH of the serving cell. |
