摘要： Disclosed is a wireless communication base station device which can prevent unnecessary HARQ retransmissions when a terminal is using a plurality of unit bands, even when the unit band through which data is transmitted differs from the unit band through which a PDCCH, to which the resource allocation information of said data is allocated, is transmitted. In this device, a control unit (102) generates, for each of a plurality of downlink unit bands, CFI information, which indicates the number of symbols used in a control channel to which resource allocation information of downlink data to be sent to the terminal has been allocated, with respect to the terminal, which communicates using a plurality of downlink unit bands; a scrambling unit (105) scrambles a control channel in a sequence corresponding to CFI information of downlink bands used in the allocation of downlink data, when, in a plurality of downlink unit bands, the downlink unit band used in the allocation of downlink data and the downlink unit band which transmits control channels to which resource allocation information has been allocated differ from one another.

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).

摘要： In a case where a second reference signal for a second communication system is transmitted in addition to a first reference signal for a first communication system, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS, DVRB resources in which a resource unit defined in a frequency-time domain is divided in a time direction and distributedly allocated at predetermined frequency intervals are used and CSI-RS is allocated in a resource ID of a part of DVRB resources and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in DVRM resources on the basis of DVRB setting information for CSI-RS, measures channel quality such as CQI, PMI or RI by using CSI-RS, and transmits and reports feedback information containing channel quality information to a transmission apparatus.
