Abstract  Abstract

increasing the amount of overhead claims even if applied channel selection as a transmission method of a response signal when the aggregation communication using a carrier of the plurality of downlink unit bands under the condition it also can restrain the uplink control channel (PUCCH) of a retransmission control method and terminal device capable of providing the method. in the terminal (200) a control unit (208) based on the uplink data generation status and the error detection result obtained by the CRC unit 211 using the transmission rule of the response signal the uplink control signal or the response signal representing generation of uplink data transmission control. number and the control unit (208) and generates the uplink control signal and the response signal in the transmission unit time under the condition according to the ACK mode error detection result and the position of ACK in mode distributes at least one of the phase point of the response signal of the resource or response signal are different.

Provided are a terminal device and a retransmission control method that make it possible to minimize increases in overhead in an uplink control channel (PUCCH) even if channel selection is used as the method to transmit response signals during carrier-aggregation communication using a plurality of downlink unit bands. On the basis of the generation status of uplink data and error-detection results obtained by a CRC unit (211) a control unit (208) in the provided terminal (200) uses response signal transmission rules to control the transmission of response signals or uplink control signals that indicate the generation of uplink data. If an uplink control signal and a response signal are generated simultaneously within the same transmission time unit the control unit (208) changes the resources allocated to the response signal and/or the phase point of the response signal in accordance with the number and position of ACKs within the error-detection result pattern.
