Provided are a radio communication terminal apparatus and a radio transmission method by which intersymbol interference of DM-RS of a CoMP terminal and a Non-CoMP terminal can be reduced. A CoMP set setting unit (102) sets the cell IDs of all cells in the CoMP set in a cell selection unit (104), and a serving cell setting unit (103) sets the cell ID of the serving cell in the cell selection unit (104). The cell selection unit (104) selects the cell ID having a number closest to the cell ID of the serving cell from the cells in the CoMP set. A sequence information calculation unit (106) derives a sequence group number from the selected cell ID, and the sequence information calculation unit (106) calculates a sequence number from the derived sequence group number and a transmission bandwidth of the DM-RS.
An integrated circuit to control a process performed by a terminal that communicates with a plurality of cells, each of which has a cell identity, in a coordinated manner that allows the plurality of cells to receive a signal from the terminal, the process comprising:
