| 20090161600 | Wireless slave unit - In a network area of a wireless network managed by a wireless master device, a wireless slave device performs wireless network communication with another wireless slave device connected by wire to a terminal, and wired network communication with a terminal connected by wire to the wireless slave device. The wireless slave device includes a wireless reception unit ( | 06-25-2009 |
| 20090168707 | RADIO COMMUNICATION DEVICE, BAND SETTING SYSTEM - An object of the present invention is to provide a wireless communication device that can receive a content by securing a band as much as possible, if a predetermined band is required to be secured when the content is received by wire. The wireless communication device judges whether or not the predetermined band necessary for receiving the content can be secured with a wireless master device. When it is judged that the predetermined band cannot be secured in the judgment, the wireless communication device switches a connection destination from the wireless master device to which the wireless communication device has been connected to a different wireless master device that can secure a predetermined receiving electric field strength. | 07-02-2009 |
| 20090190553 | RADIO COMMUNICATION SYSTEM, RADIO TERMINAL, BASE STATION, AND BASE STATION SEARCH METHOD - A wireless communication system includes a wireless terminal and a plurality of base stations that can communicate with each other via a predetermined communication path that is different from the wireless communication path to the wireless terminal. The wireless terminal transmits a request signal to one of the base stations to request a response signal from another base station. The one base station transfers the received request signal to the other base station via the predetermined communication path. Upon reception of the request signal transferred from the one base station, the second base station transmits a response signal to the wireless terminal via the predetermined channel. The wireless terminal receives the response signal transmitted from the second base station via the predetermined channel. | 07-30-2009 |
| 20090238108 | RELAY DEVICE - A relay device receives transfer data from a transfer-source terminal and transfers the received transfer data to a transfer-destination terminal via relaying performed by another relay device. When the transfer data is received, the relay device establishes direct communication with the other relay device if information regarding the other relay device is attached to the received transfer data. If information regarding the other relay device is not attached, the relay device attaches information regarding itself to the transfer data and transfers the resulting transfer data to a wireless control station. | 09-24-2009 |
| 20090238196 | NETWORK SYSTEM AND RELAY DEVICE - when a network system of the present invention performs a bandwidth-guaranteed communication, a terminal device collects information on one or more relay devices on a path to another terminal device via a bandwidth request packet transmitted to the another terminal. When the bandwidth cannot be allocated, a detour path is searched according to the collected relay device information so as to perform the bandwidth-guaranteed communication via the detour path. | 09-24-2009 |
| 20100157819 | TRANSMISSION DEVICE, TRANSMISSION METHOD, SYSTEM LSI, AND PROGRAM - One transmission rate of a physical layer (PHY rate) is selected from among a plurality of PHY rates of a protocol stack by calculating one or more effective values of transmission rates of an upper layer of the protocol stack with respect to one or more PHY rates of the plurality of PHY rates respectively, and making a comparison with use of the calculated one or more effective values. Each of the one or more effective values is calculated based on (i) an ideal value of corresponding one of the transmission rates and (ii) a retransmission ratio via the physical layer that corresponds to a reception power value detected in the reception apparatus. | 06-24-2010 |
| 20100183087 | RECEPTION DEVICE, TRANSMISSION DEVICE, AND ADAPTIVE TRANSMISSION RATE CONTROL METHOD - In a receiver | 07-22-2010 |
| 20100232415 | CONTROL DEVICE, TERMINAL DEVICE, AND COMMUNICATION SYSTEM AND COMMUNICATION METHOD, USING THE SAME - A terminal device ( | 09-16-2010 |
| 20110007901 | COMMUNICATION DEVICE - A communication device ( | 01-13-2011 |
| 20110086661 | BASE STATION AND COMMUNICATION METHOD - A base station includes: an estimation section estimating transmission condition of each of frequency channels used for communication; a reception section receiving a data signal from each communication terminal through any of the frequency channels; a measurement section measuring received signal power of the received data signal for each frequency channel; a determination section determining, for each frequency channel, whether the received data signal is demodulated errorlessly; and a control section assigning frequency channels estimated as being in good transmission condition by the estimation section, to communication terminals the data signals of which are determined as not being errorlessly demodulated by the determination section, such that a frequency channel in a better transmission condition is assigned preferentially to a communication terminal having larger received signal power detected by the detection section, and transmitting retransmission request signals requesting the communication terminals to retransmit the data signals using the assigned frequency channels. | 04-14-2011 |
