FIELD: information technology.
SUBSTANCE: user terminal transmits upstream control signal to base station using one-carrier circuit. User terminal includes module made capable to receive downstream control signal and downstream data signal; module made capable to generate acknowledgement information indicating positive confirmation or negative confirmation for downstream data signal; module made capable to generate upstream control signal including acknowledgement information; module made capable to transmit upstream control signal using other resources differing from those resources which can be used for upstream data signal; and storage module made capable to store preset correspondence relation which unambiguously correlate resources of downstream control signal or downstream data signal with resources used for upstream control signal.
EFFECT: higher quality of acknowledgement information.
