20100189027 | RADIO TRANSMISSION METHOD, RADIO RECEPTION METHOD, RADIO TRANSMISSION-RECEPTION METHOD, RADIO TRANSMISSION APPARATUS, RADIO RECEPTION APPARATUS, RADIO TRANSMISSION-RECEPTION SYSTEM, BASE STATION APPARATUS, AND COMMUNICATION TERMINAL - A radio communication base station apparatus, a radio communication terminal, and radio transmission and reception methods for a terminal to efficiently acquire the service status of the neighbor-cell before the terminal makes a cell change are provided. A subarea ID storage section | 07-29-2010 |
20100216454 | RADIO TRANSMISSION DEVICE, RADIO RECEPTION DEVICE, CELL SWITCHING METHOD, AND RADIO COMMUNICATION SYSTEM - It is possible to provide a radio transmission device, a radio reception device, and a radio communication system which can effectively use a resource of a unicast/MBMS cell and prevent increase of a signaling amount accompanying a cell switching. A UE measures a reception level of an MEMS-dedicated cell. When the measured reception level is below a first threshold value, the UE switches the serving MBMS cell from the MBMS-dedicated cell to the unicast/MBMS cell. Moreover, when the reception level of the MBMS-dedicated cell exceeds a second threshold value obtained by adding an offset value to the first threshold value, the serving MBMS cell is switched from the unicast/MBMS cell to the MBMS-dedicated cell. | 08-26-2010 |

20110317654 | WIRELESS TRANSCEIVER, WIRELESS BASE STATION, WIRELESS TERMINAL, AND WIRELESS COMMUNICATION SYSTEM - A wireless communication system comprises: a wireless base station that uses dedicated frequencies to communicate with only connected LTE-A terminals and uses shared frequencies to communicate with LTE terminals and LTE-A terminals; and an LTE-A terminal. The wireless base station comprises: a priority information creating section for setting a priority of each of the shared frequencies for idle LTE-A terminals, setting a priority of each of the plurality of frequencies for connected LTE-A terminals, and creating priority information indicative of the set priority; a system information creating section for creating system information that includes the priority information; and a transmission section for transmitting the system information. The LTE-A terminal receives system information transmitted from the wireless base station, and selects a frequency on which the LTE-A terminal camps and a frequency at which the LTE-A terminal transmits an RACH preamble based on the priority information included in the system information. In this way, the LTE-A terminal can be connected to an appropriate carrier. | 12-29-2011 |

20120100856 | MOBILE COMMUNICATION SYSTEM, TERMINAL DEVICE, AND BASE STATION - In a mobile communication system, a handover of a terminal device (MT) from a macrocell base station (eNB) to a small cell base station (HeNB) is controlled via a host device (MME or HeNB-GW). Physical cell ID deployment map information (PCI deployment map information), which includes at least information (PCI/CGI map information) indicating the correspondences between physical cell IDs and unique cell IDs of CSG cells for which access is granted, is generated in the host device (MME or HeNB-GW). When the terminal device measures the reception quality for surrounding CSG cells for handover control to any of the CSG cells, the terminal device uses the PCI deployment map information to generate a measurement result report. Thus, a service interruption caused by handover control to an inaccessible small cell can be avoided, and the wait time for handover control can be reduced. | 04-26-2012 |
