Abstract: The present invention has an object to provide a communication system capable of avoiding congestion in downlink communication or uplink communication and a shortage of radio resources arising therefrom. In the present invention, in a communication system including a normal user equipment (normal UE) that performs human to human communication and a machine type communication device (MTCD) that performs machine to machine communication, a base station device transmits a paging message to the normal UE and the MTCD for calling the normal UE and the MTCD. The paging message contains, for example, an equipment identity (UE-ID). A maximum number of equipment identities (UE-IDs) that can be accommodated within this paging message is set individually for the normal UE and the MTCD. Alternatively, the paging message contains a calling indicator in place of the equipment identity of the MTCD (UE-ID of MTCD).

Abstract: A cell2 configured by only a DL CC2 being a resource for downlink is configured. The cell2 does not include a resource for uplink, that is, a UL CC to be associated with the DL CC2 by a DL/UL link. The link information indicating the above is notified a communication terminal device by a base station device using the DL CC2. A DL CC1 and a UL CC1 constitute a cell1. The downlink communication from the base station device to the communication terminal device is performed using the cell1 and the cell2, and the uplink communication from the communication terminal device to the base station device is performed using the cell1.

Abstract: A base station device is configured to set, for each communication terminal device, a radio format for signals transmitted to and received from the communication terminal device. The radio format is set for each communication terminal device in accordance with, for example, a type of use including a moving speed of the communication terminal device. The base station device may be configured to change the radio format for the communication terminal device based on the information about a change in the environment of a radio communication between the communication terminal device and the base station device and a change including the communication terminal device's location. The signals transmitted and received between the base station device and the communication terminal device include radio formats in which at least one of a length of a symbol of the signal and a length of a cyclic prefix in an OFDM scheme differs.
