| 20100180058 | Communication System, Communication Apparatus, Communication Method, and Computer Program - In a WUSB communication environment in which isochronous transfer cannot be used, priority communication is performed in units of devices. A WUSB host manages assigning of a band of reserved one or more MASs in a superframe by using a device information management table, in which device information entries each describing, in a bitmap format, a MAS for which a transaction can be executed are each provided for a WUSB device. The WUSB host assigns at least some of the reserved one or more MASs only to a particular WUSB device. Only a WUSB device marked in a corresponding device information entry serves as a target of transaction scheduling. | 07-15-2010 |

| 20090161643 | RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION APPARATUS AND METHOD, AND PROGRAM - A radio communication system and apparatus is disclosed wherein setting necessary for communication with a desired radio communication apparatus with which a user wants to communicate can be performed with certainty by an operation system familiar to the user and a high security level can be assured for the communication which uses the setting. When a first radio communication apparatus receives a request for communication information necessary for communication through a radio network from a second radio communication apparatus through a radio circuit, it transmits identification information for the radio network and information regarding the security set in advance as communication information therein to the second radio communication apparatus through the radio circuit. The second radio communication apparatus sets the communication information to itself. The invention can be applied to a radio LAN for which a household electric appliance is used. | 06-25-2009 |
