| 20100008321 | Base-Station Apparatus, Mobile Machine, Communication System, And Channel Allocation Method - A base-station apparatus measures a frequency variation and time variation based on a signal transmitted from a mobile machine. Then, based on the measured frequency variation and time variation, the base-station apparatus allocates either an adjacent sub-channel or a distributed sub-channel to the mobile machine. With this, the base-station apparatus allocates a sub-channel according to the wireless propagation environment where the mobile machine is located. | 01-14-2010 |
| 20100128627 | BASE STATION APPARATUS, UPLINK SINR MEASURING METHOD, UPLINK SCHEDULING METHOD, AND RECEPTION-QUALITY MEASURING METHOD - A base station apparatus includes a receiving unit that receives a control signal having predetermined patterns for performing communication control processing at the base station; and a measuring unit that measures SINR of reception data that is obtained from the control signal received by the receiving unit. | 05-27-2010 |
| 20100222051 | Mobile Communication System Using Adaptive Multi-Antenna - A mobile communication system using an adaptive multiantenna realizes improvement of reception characteristics, effective use of the band, and optimization of the throughput in comparison with a system in which application of the same multiantenna communication method is continued irrespective of a variation of the number of radio relay stations. The mobile communication system comprises a radio base station, a radio relay station, and mobile terminal stations for communicating with the radio base station through a radio relay station. The radio base station has a multiantenna and is characterized in that the radio base station judges if there is any variation of the number of radio relay stations when the radio base station carries out transmission through a radio relay station, and the radio base station communicates with the mobile terminal station by switching the multiantenna communication method using the multiantenna depending on the delay time of the feedback signal from the mobile terminal station if there is a variation of the number of radio relay stations. | 09-02-2010 |
| 20100322170 | BASE STATION AND MOBILE STATION - A base station includes an identifying unit that identifies a group to which a mobile station that is to start communication belongs; a determining unit that determines a second pilot signal, which is allocated to the group identified by the identifying unit, to be a pilot signal for communication with the mobile station; and a transmitting unit that transmits information for identifying the second pilot signal to the mobile station by using a first pilot signal determined beforehand for each group as a pilot signal for notifying the information. | 12-23-2010 |
| 20100323732 | Radio Communication Method, Radio Communication Base Station Apparatus, Radio Communication Mobile Station Apparatus, And Radio Communication System - A radio communication method in a radio communication system in which radio communication is performed between a radio communication base station apparatus and a radio communication mobile station apparatus, including: transmitting, by the radio communication mobile station apparatus, an implementation loss value of the radio communication mobile station apparatus to the radio communication base station apparatus. | 12-23-2010 |
| 20100330902 | Radio Relay Method, Base Station Apparatus, And Relay Station Apparatus - A radio relay method for relaying signal transmitted and received between a base station apparatus and a mobile station apparatus, the radio relay method including: selecting a first relay method amplifying and transmitting reception signal, or a second relay method decoding, error correcting, re-encoding, and transmitting the reception signal, based on each reception quality between the relay station apparatus and the base station apparatus and between the relay station apparatus and the mobile station apparatus; and relaying the signal based on the selected first relay method or the selected second relay method. | 12-30-2010 |
| 20110074731 | INPUT DEVICE, INPUT PROCESSING PROGRAM, AND INPUT CONTROL METHOD - An input device and input control method including: a capacitance measurement unit to measure capacitances of a plurality of electrodes arranged on a touch panel; a deflection determination unit to determine a presence or absence of a deflection occurring in the touch panel based on a distribution of results of the capacitances of the electrodes; and a coordinate output unit to output coordinate data of an operation input on the touch panel based on the distribution of results. | 03-31-2011 |
| 20110158099 | COMMUNICATING DEVICE AND METHOD OF CONTROLLING COMMUNICATING DEVICE - A communicating device capable of transmitting packets to a destination device via any of a plurality of adjacent devices, has a first measuring unit for measuring a first quality of a link between the communicating device and the destination device for a first period of time, a second measuring unit for measuring a second quality of a link from the communicating device to the destination device for a second period of time shorter than the first period of time, a first selector for selecting an adjacent device from the plurality of adjacent devices based on the measured first quality when transmitting a new packet to the destination device, and a second selector for selecting an adjacent device from the plurality of adjacent devices based on the measured second quality upon failure of transmitting the new packet. | 06-30-2011 |
