Patent ID: 7974177

Claim:
A user equipment terminal transmitting at least an uplink control channel to a base station apparatus using a single carrier method, the user equipment terminal employing persistent scheduling in which a predetermined resource is periodically allocated in advance, the user equipment terminal comprising: a determination unit that provides data arrival acknowledgement information indicating an acknowledgement response or a negative acknowledgement response as a response to a downlink data channel; an estimation unit that provides channel quality information indicating downlink channel quality; a control channel generation unit that generates an uplink control channel including at least one of the data arrival acknowledgement information and the channel quality information; and a transmission unit that, when no resource for transmitting an uplink data channel is allocated, transmits the uplink control channel using a radio resource dedicated to the persistent scheduling, wherein the uplink control channel includes at least one unit block including a sequence in which a same complex number is multiplied to each chip of an orthogonal code sequence the user equipment terminal.
