Radio Station and Method of Processing User Data With Radio Station

A radio station that is used in a radio communication network and is capable of transmitting and receiving user data including downlink user data and uplink user data to and from a plurality of mobile stations via an air interface, the radio station comprising:

• a first part;
• and
• at least one second part that can be arranged so as to be physically separated from the first part and is connected to the first part via a transmission line so as to be able to communicate with the first part, wherein
• the first part comprises:
• a first scheduling unit configured to perform dynamic scheduling to allocate a plurality of radio resources to the plurality of mobile stations or the user data;
• and
• a first signal processing unit capable of performing digital signal processing in order to transmit the downlink user data to the air interface and to restore the uplink user data from a signal received from the air interface, and
• the second part comprises:
• a second signal processing unit capable of performing, instead of the first signal processing unit, digital signal processing for a first mobile station connected to the second part;
• and
• an analog signal processing unit configured to perform analog signal processing including at least one of frequency conversion and power amplification to provide an air interface to the first mobile station.
