摘要： Disclosed are a terminal, a base station, a response method, and a retransmission control method, which are capable of switching the response signal transmission method while preventing throughput degradation and without increasing the number of signaling bits. A bundling determination unit (132) of a terminal (100) determines parameters that denote the allocated resource quantities that are allocated thereto from a base station (200), or in other words, a downstream band that is included in a bundling group and a downstream band that is not included in the bundling group, from among a plurality of downstream bands on the basis of base station transmission parameters. Specifically, a degree of resource share (Xn) that is allocated from each respective downstream band to the terminal (100) is employed in the base station transmission parameters.

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： 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.

摘要： Provided are a wireless transmission device, a wireless reception device, and a bandwidth allocation method for, when non-contiguous bands allocation is performed, improving the frequency resource use efficiency of a system and thereby improving the system performance.
