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： Disclosed are a wireless communication base station device, a wireless communication terminal device, and a wireless communication method with which the amount of signaling is reduced while maintaining a high scheduling gain. A judgment unit (117) stores in advance a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality that is output by an estimation unit (109), and the maximum value for the number of clusters that is output by the judgment unit (117), a scheduling unit (118) schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

摘要： Provided is a terminal apparatus in which, a transmission control unit (204) controls the transmission power of a sounding reference signal (SRS) by use of an offset value relative to the transmission power of a data signal, and a transmission unit (206) transmits the SRS by use of the transmission power as controlled. If a subframe to be used for transmitting the SRS is a predetermined subframe, the transmission control unit (204) uses a first offset value to control the transmission power of the SRS. Otherwise, the transmission control unit (204) uses a second offset value to control the transmission power of the SRS. The second offset value is an offset value that has been established so as to be transmitted to the serving cell of the terminal (200), and the first offset value is greater than the second offset value.

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.

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).

摘要： The present invention provides a terminal device that allows constraints on user allocation to be prevented and spread codes to be allocated in a scheduler when non-adaptive HARQ is employed using a PHICH. A codeword generator (103) generates code words (CW) by encoding data, a layer mapping unit (108) places each CW in one or a plurality of layers, a DMRS generator (110) generates a reference signal for each layer in which a CW is placed by using any resource among a plurality of resources defined by a mutually orthogonal plurality of OCCs, and an ACK/NACK demodulator (102) receives a response signal indicating a retransmission request. When a response signal requesting retransmission of only a CW placed in a plurality of layers is received, the DMRS generator (110) uses each resource having the same OCC among the plurality of resources for the reference signals generated in the corresponding layers.
