MOBILE COMMUNICATION SYSTEM, BASE STATION DEVICE, USER DEVICE AND METHOD

摘要

A single carrier method uses a user device which transmits at least an upstream control channel. The user device includes: means for preparing channel state information indicating a downlink radio propagation condition; and transmission means for transmitting an upstream control channel containing channel state information in a predetermined dedicated band when no radio resource is allocated for transmission of the upstream data channel. The transmission means transmits a predetermined number of unit blocks for each slot cycle. When the system bandwidth is greater than a predetermined value, a set of predetermined number of factors multiplied on a predetermined number of unit blocks containing the same content in the same slot expresses an orthogonal code sequence while a predetermined number of symbol elements constituting one unit block expresses at least a part of the channel state information.
