摘要： A wireless communication apparatus capable of minimizing the degradation of the separation characteristic of response signals to be code-multiplexed. In the apparatus, a control part (209) controls both a ZC sequence to be used for the primary spread in a spreading part (214) and a Walsh sequence to be used for the secondary spread in a spreading part (217) according to the associations between sequences and CCEs established in accordance with the probability of using response signal physical-resources corresponding to CCE numbers. The spreading part (214) performs the primary spread of the response signal by use of the ZC sequence established by the control part (209). The spreading part (217) performs the secondary spread of the response signal, to which CP has been added, by use of the Walsh sequence established by the control part (209).

In a radio communication apparatus for transmitting data using multiple code words, as response time taken by a transmitting station to receive a response signal (Ack/Nack signal) after the data is transmitted from the transmitting station (BS) to a receiving station (UE), a cycle of second response time (RTT2) corresponding to a low-order code word is longer than a cycle of first response time (RTT1) corresponding to a high-order code word. In the receiving station, received data of the low-order code word is decoded using at least one of retransmission data and the first received data of the high-order code word and response signals are respectively generated according to a decoding result of each of the code words and notification of the response signal is provided. In the transmitting station, the response signal is acquired at timing of each of the code words and retransmitting control by HARQ is performed.

摘要： An eigen value expansion section 103 calculates eigen values and eigen vectors in a correlation matrix or covariance matrix of input signals. When the ratio between a maximum eigen value and other eigen values is equal to or lower than a threshold, an assignment method selection section 104 selects a code assignment method whereby systematic bits are transmitted with their respective eigen vectors. As a result, a communication apparatus 100 transmits a systematic bit X with the respective eigen vectors. On the other hand, when the ratio between a maximum eigen value and other eigen values is greater than the threshold, the assignment method selection section 104 selects a code assignment method whereby systematic bits are transmitted with only the eigen vector having the maximum eigen value. As a result, the communication apparatus 100 transmits the systematic bit X with only the eigen vector having the maximum eigen value. This makes it possible to obtain an effect of improving sufficient communication quality even when the difference between the maximum eigen value and other eigen values is large in a communication system which combines a turbo code and MIMO.
