Abstract  Abstract

The invention reduces the interference between the code of the DM-RSes of the CoMP terminal and Non-CoMP terminal of wireless communication terminal device and wireless transmission method is provided. CoMP set setting unit (102) sets cell IDs of all cells in CoMP set setting to the cell selection unit (104) serving cell setting unit (103) sets a cell ID of a serving cell set to the cell selection unit (104). cell selection unit (104) from the cell of the CoMP set is closest to the cell ID of the cell ID of the serial number and the service cell is selected. The sequence information calculation unit (106) selecting the cell ID derived sequence group number and calculating unit by the sequence information (106) calculating sequence number according to the transmission bandwidth of the derived sequence group number and DM-RSes.

Provided are a radio communication terminal device 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.
