Abstract
Official abstract text for this publication.
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, a control unit in the provided terminal 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 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An integrated circuit to control a process, the process comprising: transmitting, to a terminal configured with one or more downlink component carriers, downlink assignment information indicating resources for downlink data, wherein the resources are respectively assigned to the downlink component carriers; transmitting the downlink data to the terminal; receiving a response signal for the downlink data, the response signal being transmitted from t…
