Title:
TERMINAL DEVICE AND SIGNAL TRANSMISSION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2010/146855
Kind Code:
A1
Abstract:
Provided is a terminal device which enables a reduction in terminal power consumption while maintaining single carrier characteristics even when an SR and a response signal are generated in the same sub-frame in carrier aggregation. Specifically provided is a terminal (200) which communicates with a base station using a unit band group configured from N (N is a natural number of 2 or more) downlink unit bands and uplink unit bands, wherein when an uplink control signal and a response signal are generated within the same transmission unit time, downlink assignment control information is received only in a downlink unit band of the unit band group, the downlink unit band being associated with another uplink unit band different from a specific uplink unit band to which a resource for transmitting the uplink control signal is assigned, a control unit (208) transmits, through an uplink control channel in said another uplink unit band, the response signal with respect to downlink data transmitted through a downlink data channel indicated by the downlink assignment control information, and does not transmit the uplink control signal.
