摘要： In a communications system including a base station capable of altering a frequency bandwidth which is used for transmitting broadcast data for providing point-to-multipoint broadcasting communications service and which is used for transmitting individual communications data for providing point-to-point individual communications service, and a mobile terminal capable of altering a receivable bandwidth which is used for receiving at least the broadcast data and the individual communications data transmitted from the base station, decision processing of making a decision as to whether the mobile terminal can receive reception-desired content it desires to receive among contents provided by the broadcasting communications service is executed in accordance with a frequency occupying bandwidth used for transmitting the reception-desired content. Thus, the mobile terminal becomes able to make a decision as to whether it can receive particular E-MBMS content considering its own UE position.

摘要： The present invention has an object to provide a communication system capable of minimizing effects due to a delay among a plurality of base station devices as much as possible in scheduling for communication with a terminal device in cooperation among the plurality of base station devices. Cells1 to 3 can each perform scheduling without using information for scheduling notified from one or a plurality of cells among pieces of information for scheduling notified from other cells. For example, in a case where an interface between the cell1 and cell3 has a large delay amount, the cell1 performs scheduling without using information S13 notified to the cell1 by the cell3, and the cell3 performs scheduling without using information S11 notified to the cell3 by the cell1.

摘要： An object of the present invention is to provide a communication system capable of preventing a base station device from being occupied by specific communication terminal devices and preventing a situation in which the base station device cannot accommodate other communication terminal devices. In the present invention, in Step ST1403, a HeNB_A notifies UEs being served thereby of the MTCD restriction information indicating the operation of restricting MTCDs. Among the UEs that have received the MTCD restriction information in Step ST1404, an MTCD operates in accordance with the MTCD restriction information. Specifically, in Step ST1406, the MTCD judges whether or not the MTCD can select, as a suitable cell, a cell judged to satisfy cell selection criteria in Step ST1402. In a case of judging that the cell can be selected, the MTCD selects the cell as a suitable cell in Step ST1407.

摘要： A mobile communication system includes a plurality of eNBs that perform radio communication with an UE and an MCE that controls the eNBs. The MCE indicates an MBSFN subframe (MCE) serving as radio resources that transmit a reference signal for power measurement to the UE less frequently than normal to the eNB, the eNB, in addition to the MBSFN subframe (MCE) indicated by the MCE, designates the MBSFN subframe (eNB) serving as the radio resources that transmit a reference signal to the UE less frequently than normal, and in the MBSFN subframe (MCE) and the MBSFN subframe (eNB) the reference signal is transmitted to the UE. In this manner, the reference signal for measuring a power can be transmitted less frequently than normal, and a power consumption of the infrastructure can be reduced.
