Abstract:
A disclosed user device generates an uplink control channel including at least one of acknowledgement information and a channel quality indicator regarding downlink and transmits the uplink control channel via a dedicated frequency band when no resource is allocated for transmission of an uplink data channel. The uplink control channel includes multiple unit blocks constituting a subframe and each of the unit blocks includes a sequence generated by multiplying all chips of an orthogonal code sequence assigned to the user device by the same factor.
