摘要： 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 (101) sets whether the terminal (100) thereof is a CoMP terminal or a Non-CoMP terminal. When the terminal (100) is set as a Non-CoMP terminal, the hopping pattern calculating unit (104) 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 (100) is set as a CoMP terminal, the hopping pattern calculating unit (104) 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 (105) generates a ZC sequence to be used as an SRS, using the calculated ZC sequence number.

摘要： Provided is a wireless communication apparatus by which reduction of a diversity gain can be suppressed at minimum in the case of employing a repetition technology in multicarrier communication. In the wireless communication apparatus (100), repetition sections (102-1 to 102-n) repeat each data symbol inputted from modulating sections (101-1 to 101-n) to create a plurality of identical data symbols. An allocating section (103) outputs each data symbol to a multiplexing section (105) by allocating the data symbol to a plurality of subcarriers constituting an OFDM symbol. At this time, the allocating section (103) allocates at least one of the repeated identical symbols to a subcarrier different from a subcarrier to which the symbol is allocated in an adjacent sector.

摘要： In ARQ where a plurality of mobile stations share and use a single channel for response signals (ACK/NACK signals), a wireless communication base station apparatus can prevent failure of the ARQ control. In this apparatus, a CRC part (114) performs an error detection using CRC for an uplink data, and generates, as a response signal, an ACK signal in a case of CRC=OK or a NACK signal in a case of CRC=NG. A retransmittal determining part (115) determines whether the response signal is for an initially transmitted data or for a retransmitted data. A constellation control part (116) controls, in accordance with a determination result of the retransmittal determining part (115), a constellation pattern to be used in a modulation in a modulating part (105). The modulating part (105) modulates the response signal for the retransmitted data in accordance with the constellation pattern controlled by the constellation control part (116), that is, a constellation pattern obtained by reversing the constellation pattern of the response signal for the initially transmitted data.
