Abstract
Provided are a wireless communication apparatus and a reference signal generating method, wherein inter-cell interference is reduced inside and outside a CoMP set. A CoMP mode setting unit () sets whether the terminal () thereof is a CoMP terminal or a Non-CoMP terminal. When the terminal () is set as a Non-CoMP terminal, the hopping pattern calculating unit () calculates a ZC sequence number to be used as the transmission timing, from among all the ZC sequence numbers that can be used within the system. When the terminal () is set as a CoMP terminal, the hopping pattern calculating unit () calculates a ZC sequence number to be used as the transmission timing, by hopping the ZC sequence numbers to be used within the CoMP set. A ZC sequence generating unit () generates a ZC sequence to be used as an SRS, using the calculated ZC sequence number.
