| 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 |

| 20110300867 | TERMINAL DEVICE, HOME BASE STATION, AND HOME BASE STATION SWITCHING DEVICE - A wireless communication system comprises an MME ( | 12-08-2011 |
| 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 |
