In a case where printing control is configured using a unified user interface and bookbinding printing has been set, bookbinding format conditions are judged and functions possessed redundantly by first and second information processing units are controlled to make appropriate printing control possible in conformity with settings made by a user. The method comprises receiving uplink channel condition information of the UE from the UE, and receiving UE transmission power class information from the RNC; and reading total transmission power corresponding to the received UE transmission power class from the table, and determining a data rate of the UE considering the uplink channel condition information and the total transmission power. Here, the first region and the second region are multiplexed in the first downlink subframe in accordance with a frequency division multiplexing scheme. A process within the first portable device controls input from both the first and second keyboard portions, and causes the display of characters on a display coupled to one of the portable devices.
