20120157143 | WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION APPARATUS, AND WIRELESS COMMUNICATION METHOD - A wireless communication apparatus includes: a receiving unit that receives a signal indicating a frequency band having the highest priority of selection among a plurality of frequency bands; and a transmitting unit that transmits data in parallel, using the frequency band having the highest priority of selection and a frequency band having a priority of selection lower than that of the frequency band having the highest priority of selection. | 06-21-2012 |
20120221245 | COMMUNICATION SYSTEM, COMMUNICATION APPARATUS, COMMUNICATION METHOD, AND COMMUNICATION PROGRAM - A position measuring unit measures a position. An area determining unit determines a means of movement. A position measurement result transmission determining unit determines, based on the means of movement determined by the area determining unit, whether or not to transmit the position measurement result of the position measuring unit to the information-providing apparatus. A transmitting unit transmits, in the case in which the position measurement result transmission determining unit determines to transmit the position measurement result to the information-providing apparatus, the position measurement result to the information-providing apparatus. | 08-30-2012 |
20120263130 | WIRELESS COMMUNICATION SYSTEM - In a wireless communication system, a terminal device and a base station device communicate using frequency bands selected from among a plurality of frequency bands. The base station device selects a frequency band used for a downlink and a frequency band used for an uplink as frequency bands used for communication with the terminal device from among the plurality of frequency bands, selects an association between the frequency band used for the downlink and the frequency band used for the uplink among the selected frequency bands, and transmits information indicating the selected frequency bands and information indicating the association containing identification information of the association using a signal specific to the terminal device. | 10-18-2012 |
20120322486 | WIRELESS COMMUNICATION SYSTEM, BASE STATION APPARATUS, COMMUNICATION APPARATUS, AND COMMUNICATION CONTROL PROGRAM - A CA decision part selects a component carrier to be used for communication with a terminal apparatus from component carriers used for communication by a plurality of base station apparatuses. A CA set notification part notifies a sub-base station apparatus of carrier aggregation information indicating the component carrier selected by the CA decision part. A transmission unit of a main base station apparatus allocates a signal, which is obtained by modulating a part of data to be transmitted to the terminal apparatus, on a first component carrier selected by the CA decision part, and transmits the signal. A transmission unit of the sub-base station apparatus allocates a signal, which is obtained by modulating a part of the data to be transmitted to the terminal apparatus, on a second component carrier indicated by notified carrier aggregation information, and transmits the signal. A reception unit of the terminal apparatus receives the signal from the main base station apparatus using the first component carrier and the signal from the sub-base station apparatus using the second component carrier. A wireless processing part integrates the signals received by the reception unit. | 12-20-2012 |

A resource information acquiring unit converts CC-ID extracted from control information into frequency band information. | 01-03-2013 |
20130208615 | COMMUNICATION TERMINAL, BASE STATION, WIRELESS COMMUNICATION SYSTEM, CONTROL METHOD AND PROGRAM THEREFOR, AND RECORDING MEDIUM HAVING CONTROL PROGRAM RECORDED THEREON - According to a control method of a wireless communication system in which wireless communication between a base station ( | 08-15-2013 |
20140146737 | MOBILE STATION, BASE STATION, COMMUNICATION SYSTEM, DISPLAY CONTROL METHOD, COMMUNICATION CONTROL METHOD, AND PROGRAM - A mobile station is provided to which multimedia broadcast/multicast service can be applied also during carrier aggregation. A mobile station communicates with a base station by carrier aggregation using a plurality of component carriers having different frequency bands. The mobile station receives contents in MBMS from the base station using at least two component carriers of a plurality of component carriers. The mobile station causes a display to display the received contents. | 05-29-2014 |
20150050932 | WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, MOBILE STATION DEVICE, AND BASE STATION DEVICE - A wireless communication system includes a first base station device, a second base station device, and a mobile station device configured to communicate with the first and second base station devices. The first base station device includes a request notifying unit configured to notify the mobile station device of a request for carrier aggregation. The mobile station device includes: a cell search unit configured to, upon receiving the request, perform cell search and thereby search the second base station device available for carrier aggregation; and a base station notifying unit configured to notify the first base station device of information indicating the second base station device detected by the cell search unit performing the cell search. | 02-19-2015 |
20150055572 | WIRELESS COMMUNICATION SYSTEM, COMMUNICATION METHOD, TERMINAL DEVICE, AND BASE STATION - A more preferable communication control method and the like in a wireless communication system allowing usage of a plurality of wireless transmission methods are provided. The wireless communication system includes at least one base station providing services in accordance with the plurality of wireless transmission methods respectively, and a terminal device connected to the base station.
