Abstract:
The present invention is to provide base station apparatuses and mobile station apparatuses suitable for a configuration of a distributed wireless communications system, configure the distributed wireless communications system, and provide a pilot channel generation method and synchronization generation method suitable for the distributed wireless communications system. Provided are a control signal generating section 13 which generates a plurality of mutually different first pilot signals and a second pilot signal based on control data input from the core network apparatus CN constituting the distributed wireless communications system, combines the first pilot signals and the second pilot signal, and thereby generates specific pilot channels for each of radio access unit apparatuses, and a transmitting section 10 that transmits the specific pilot channels respectively to the radio access unit apparatuses.
