  • Publication number: 20130343214
    Abstract: Appropriate communication is performed even before a CQI report is acquired. A base station device 1b that performs radio communication with a terminal device 2 includes: a report acquisition section that acquires the CQI report from the terminal device; and a selection section that selects a transmission state. The transmission state includes a first transmission state in which transmission is performed using a first radio resource subset A configured to include a radio resource that does not suffer interference from another base station device 1a, and a second transmission state in which transmission is performed using at least a second radio resource subset B configured to include a radio resource that is likely to suffer interference from another base station device 1b. The report acquisition section 14 acquires the CQI report of the second radio resource subset from the terminal device 2.

  • Publication number: 20130329234
    Abstract: The spatial information detection device emits, to a space including an intended area, signal light defined as light modulated with a modulation signal defined as a square wave signal having high and low level periods appearing alternately, each of the periods having its length randomly selected from integral multiples of a unit time period. The device generates signal electric charges by accumulating electric charges generated in response to light from the space in a collection time period determined by a demodulation signal defined as a signal having the same waveform as that of the modulation signal or that of the inverted modulation signal. The device corrects, using correction information regarding an effect caused by light from an unintended area, the amount of signal electric charges as an amount of intended electric charges produced in response to light from the intended area, thereby generating spatial information.

  • Publication number: 20130217403
    Abstract: A resource used by a wireless terminal device to communicate with a terminal device in an internal network is appropriately managed. In a communication system 201, an internal network connection device 102 allocates, to a wireless terminal device 150, 151, its own resource for communicating with a terminal device 161 in an internal network 51, transmits data received from the wireless terminal device 150, 151 via the wireless base station device 101, to the terminal device 161, and transmits data received from the terminal device 161, to the wireless terminal device 150, 151 via the wireless base station device 101. The internal network connection device 102 or the wireless base station device 101 determines whether or not the allocation of the resource to the wireless terminal device 150, 151 should be maintained. Upon receiving a determination that the allocation of the resource should not be maintained, the internal network connection device 102 cancels the allocation of the resource.
