Abstract:
1. A user apparatus for transmitting at least an uplink control channel to a base station apparatus in accordance with a single-carrier scheme, comprising: a determination unit configured to generate acknowledgement information indicating a positive response or a negative response to a downlink data channel; an estimation unit configured to generate channel condition information indicating a downlink channel condition; a control channel generation unit configured to generate an uplink control channel including at least one of the acknowledgement information and the channel condition information, the uplink control channel further including one or more unit blocks including a sequence resulting from multiplication of a uniform factor with all chips of an orthogonal code sequence for a cyclic shift amount individually indicated from the base station apparatus to the user apparatus, different cyclic shift amounts being assigned to different user apparatuses; and a transmission unit configured to transmit the uplink control channel in a predefined dedicated band if no resource is assigned to transmit an uplink data channel, and wherein a pattern of multiple factors represents the acknowledgement information or the channel condition information.
