    摘要： A quadrature modulation circuit includes a low pass filter which operates by a time division process for the in-phase channel and quadrature-phase channel, and reduces address requirements data using amplitude symmetry of the wave form and/or using symmetry wave form on the time axis. The capacity of the ROM is reduced by half or more and the configuration of the quadrature modulation circuit is simplified.

    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： An object of the present invention is to provide a base station device and a communication system allowing flexible use of frequency resources and capable of improving use efficiency of frequency resources while increasing a data rate. In the present invention, 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.

    摘要： 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).

    摘要： A mobile communication system hybridly allows, in a case where an access group consisting of one or more user equipments and one or more base stations is registered, the base station included in the access group to have access in a closed mode from the user equipment included in the same access group and access in an open mode from a user equipment that is not included in the same access group, wherein a communication area of the base station in the open mode is identical to a communication area of the base station in the closed mode. This eliminates a communication area in which the base station serving as an access destination differs between the user equipment in the closed mode and the user equipment in the open mode.
