Abstract  Abstract

The invention claims a retransmission control method and terminal device can provide the method for overhead claims even carrier wave polymerizing communication to a plurality of downlink unit bands as the response signal sending method applied the selected channel suppressed uplink control channel (PUCCH). Wherein the terminal (200) a control unit (208) based on the generated state of uplink data and the error detection result obtained according to CRC unit (211) the transmission rule of the response signal according to the resource distribution sending uplink data generated by uplink control signal or sending control of the response signal. And when the control unit (208) in the transmission unit time at the same time produce uplink control signal and the response signal according to the position of the ACK in the number of ACK mode error detection result and mode the resource distribution response signal or the response signal of the phase position points of at least one different from each other.

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.
