TERMINAL DEVICE, COMMUNICATION METHOD AND INTEGRATED CIRCUIT

WIPO Patent Application WO/2014/073671

A1

In the present invention, a base station device and a terminal device determine mapping of a resource element to which a PDSCH is mapped in order to achieve efficient communications. The terminal device uses the first parameter set among up to four parameter sets during decoding of a PDSCH transmitted from antenna port 7 in order to determine mapping of a resource element (RE) for the PDSCH, said PDSCH being determined upon detecting a physical downlink control channel (PDCCH) or enhanced physical downlink control channel (EPDCCH) having downlink control information (DCI) format 1A, or uses the number of antenna ports and/or frequency positions of cell-specific reference signals (CRS) within a serving cell during the decoding of the PDSCH if transmitted from antenna port 0 through 3 in order to determine the RE mapping for the PDSCH, said PDSCH being determined upon detecting the PDCCH or EPDCCH having DCI format 1A.
