    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: Disclosed are a wireless communication method, a wireless communication base station device, and a wireless communication terminal device that dynamically switch the transmission slot of an SRS of each terminal within a cell while suppressing an increase in the number of signaling bits. A terminal (100) and a base station (200) are each provided with a table wherein FH flags for SRS and transmission power data of each slot are mapped to two-bit notification bits. In this table, transmission power data indicating SRS transmission by slot 1 and slot 2 and FH flags are mapped, and an FH flag is not mapped to transmission power data indicating SRS transmission by slot 1 or slot 2. The base station (200) notifies the terminal (100) of the FH flag data and the SRS transmission power data by means of transmitting scheduling data containing the notification bits to the terminal (100).

    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.

    摘要: A radio communication apparatus is provided that enables degradation of error rate performance due to puncturing to be minimized when an LDPC code is used as an error correcting code. In this apparatus, a padding bit insertion section 101 inserts padding bits in a transmission bit sequence based on a parity check matrix, and outputs the generated bit sequence to an LDPC encoding section 102. Using the parity check matrix, LDPC encoding section 102 performs LDPC encoding on the bit sequence input from padding bit insertion section 101, and obtains an LDPC codeword composed of systematic bits and parity bits. Then a puncturing section 103 eliminates padding bits from the LDPC codeword input from. LDPC encoding section 102, and also punctures parity bits in the LDPC codeword in order starting from a parity bit corresponding to a variable node for which the total number of connections to padding bits via check nodes is larger.
