20090059859 | COMMUNICATION DEVICE - In a communication apparatus, a grouping unit determines an adaptability based on a reception quality notified by a mobile station located in a cell, and groups mobile stations or connections by each of adaptabilities; an adaptability-based frame-occupancy-rate determining unit determines a data-mapping amount (an available capacity) by each of the adaptabilities depending on an amount of interference; and a frame mapping unit controls the mobile stations or the connections grouped by each of the adaptabilities to be mapped to a wireless frame by each frame based on the determined data-mapping amount. | 03-05-2009 |
20090125778 | COMMUNICATION SYSTEM, TRANSMISSION-SIDE COMMUNICATION DEVICE, AND RECEPTION-SIDE COMMUNICATION DEVICE - Within a communication system in which an ARQ control is exercised, in a transmission-side communication apparatus | 05-14-2009 |
20100272202 | DATA TRANSMISSION DEVICE, DATA RECEPTION DEVICE, AND WIRELESS COMMUNICATIONS SYSTEM - When an error correction decoding unit | 10-28-2010 |
20140036765 | RELAY SATELLITE AND SATELLITE COMMUNICATION SYSTEM - A relay satellite includes reception antennas, reception processing units, transmission processing units, transmission antennas, a reception analog switch matrix unit that outputs a signal received by the reception antenna to one or more of the reception processing units, a digital switch matrix unit that outputs digital reception signals obtained by reception processing performed by the reception processing units to one or more of the transmission processing units, and a transmission analog switch matrix unit that outputs analog signals obtained by transmission processing performed by the transmission processing units to one of the transmission antennas. The reception analog switch matrix unit outputs a broadband reception signal to the reception processing units when a reception signal having a band broader than a band processable by the reception processing unit is inputted, and the reception processing unit performs reception processing on a part of a band when the broadband signal is inputted. | 02-06-2014 |

20100150035 | Method for Signaling Center Frequencies for WiMAX Repeaters - A wireless network includes a base station (BS), a set of mobile stations (MS), and a set of repeaters. The channels between the BS and the repeater and between the repeater and the MS include a downlink (DL) and an uplink (UL). A BS specifies a first center frequency F | 06-17-2010 |
20100220682 | Method for Optimizing Performance in Multi-Cell OFDMA Networks - A method optimizes a performance of a multi-cell orthogonal frequency-division multiple access (OFDMA) network that includes a set of base stations (BSs) located in a cell, and each BS transmits data on downlink channels to a set of mobile stations (MSs) in the cell. Each BS acquires channel state information (CSI) and inter-cell interference information (ICI) for each downlink channel to each MS in the cell. Each BS selects a power level and a modulation coding scheme level (MCS) for transmitting the data to each MS on the downlink channels based on the CSI and ICI, such that a bit rate is maximized and the ICI is minimized. Then, time and frequency resource are allocated for transmitting the data on the downlink channels to the set of MSs, such that the allocated resources are minimized to optimize the performance of the network. | 09-02-2010 |

20100034128 | TLV for Supporting DSx and R2 Signaling Procedures for MCBCS in WiMax Networks - A method for signaling in a wireless network, including a base station (BS) in a cell, wherein the network operates according to the IEEE 802.16 standard, exchanges messages between a subscriber station (SS), when the SS enters the cell. The messages indicate whether the SS and the BS are enabled to use an Upper Layer Signaling (R2) and a Dynamic Service Addition/Change (DSA/DSC) signaling (DSx) for multi-cast broadcast services (MBS) for subsequent message exchanged between the SS and the BS, after the SS is admitted into the cell. | 02-11-2010 |

20090099749 | Vehicle collision decision apparatus - The vehicle collision decision apparatus has first acceleration detectors and a second acceleration detector for detecting an acceleration of the vehicle in a longitudinal direction, and third acceleration detectors for detecting an acceleration of the vehicle in a transverse direction thereof. When the vehicle is involved in an offset collision, the front airbags of the vehicle are activated based on accelerations detected by the first acceleration detectors and the second acceleration detector. Thereafter, the curtain airbags of the vehicle are reliably activated. | 04-16-2009 |
