Abstract: A processing device that is an edge computer connected to a base station communicatable with a vehicle in a service area includes: a request generation unit generating a first request including location information and a range from the location information specifying a region in which information sharing is requested, and an identifier from which a demander that requests the information sharing is identifiable; an accepted request holding unit holding a second request based on an information sharing demand from another processing device when shared information regarding the region is sendable in response to the second request; and a request location information inquiry unit generating the shared information including a cognitive event and the identifier held in the accepted request holding unit when location information indicating a cognitive event occurrence point acquired from the vehicle via the base station is included in a region specified by the second request information.

Abstract: A control apparatus (10) generates probe data from sensing data obtained by sensing objects in a mobile object's surroundings. The control apparatus (10) selects at least some pieces of probe data as transmission data from the probe data generated, according to a communication resource determined according to a role of the mobile object. The control apparatus (10) transmits the transmission data selected to a management server (20). The management server (20) updates management data such as a dynamic map based on the transmission data.

Abstract: A communication device (201) receives internal electric waves (302) emitted toward inside a vehicle (100) by an internal communicator (102) mounted in the vehicle (100), and receives external electric waves (303) emitted toward outside the vehicle (100) by an external communicator (103) mounted in the vehicle (100). The communication device (201) determines whether the communication device (201) is inside the vehicle (100) or outside the vehicle (100), from a reception intensity of the received internal electric waves (302) and from a reception intensity of the received external electric waves (303).

Abstract: A communication master device (101) manages a plurality of communication slave devices (102). An investigation unit (301) investigates status of retention of transmission waiting data in the plurality of communication slave devices (102). A period specification unit (302) specifies a length of a transmission permitted period in which transmission of the transmission waiting data is permitted and a length of a transmission prohibited period in which the transmission of the transmission waiting data is prohibited, based on the status of the retention of the transmission waiting data in the plurality of communication slave devices (102).

Abstract: A plurality of wireless communication channels (30) are set between a wireless communication apparatus (20) and a communication destination apparatus (10). The wireless communication apparatus (20) receives connection check response data, which is a response from the communication destination apparatus (10) in response to connection check request data transmitted to the communication destination apparatus (10) through any of the wireless communication channels (30), through the wireless communication channel (30) through which the connection check request data have been transmitted. In addition, the wireless communication apparatus (20) analyzes a condition of reception of the connection check response data of each of the wireless communication channels, and selects a wireless communication channel (30) through which connection check request data is to be transmitted, from among a plurality of wireless communication channels (30), on the basis of a result of analysis.

Abstract: A base station in a wireless includes: a surrounding AP measurement unit that instructs terminal stations to execute a base station search operation and searches for another base station; a channel quality evaluation unit that evaluates available wireless channels on the basis of the result of the base station search by the surrounding AP measurement unit and the result of the base station search by each of the accommodated terminal stations; a channel selection unit that selects a wireless channel for use on the basis of the result of the evaluation; and a channel setting unit that instructs the terminal stations to switch to a wireless channel selected by the channel selection unit for communication and switches a wireless channel for its own use to the wireless channel selected by the channel selection unit.

Abstract: A wireless device includes a wireless-signal reception unit that decodes a wireless signal, a wired-signal transmission and reception unit that acquires data to be distributed, a distribution-status management unit that holds a management table, a proxy-distribution determination unit that determines whether to perform retransmission of data or perform proxy distribution, a proxy-distribution wireless-device selection unit that selects a proxy-distribution wireless device, a distribution-method selection unit that selects a data distribution method of the proxy-distribution wireless device, and a wireless-signal transmission unit that modulates data and transmits a wireless signal.

Abstract: A wireless communication apparatus includes a BT-apparatus unit configured to perform wireless communication using frequency hopping, a WLAN-apparatus unit configured to perform wireless communication in a system different from a system of the BT-apparatus unit using a band including at least a part of a band used by the BT-apparatus unit and using a WLAN-antenna whose directionality is controllable, and an information managing unit configured to, upon detecting simultaneous communication of the BT-apparatus unit and the WLAN-apparatus unit, instruct the WLAN-apparatus unit to perform communication while adjusting a beam direction of the WLAN-antenna and instruct the BT-apparatus unit to measure a communication quality, determine a directionality setting value of the WLAN-antenna based on the communication quality measurement by the BT-apparatus unit, and instruct the WLAN-apparatus unit to perform communication using the determined directionality setting value.

Abstract: A BT apparatus unit configured to perform Bluetooth (registered trademark) communication, a WLAN apparatus unit configured to perform WLAN communication, and an information managing unit configured to acquire a WLAN communication frequency band, which is a frequency band used for the WLAN communication, from the WLAN apparatus unit, determine an unusable frequency band based on the acquired WLAN communication frequency band, and notify the BT apparatus unit of the determined unusable frequency band. The BT apparatus unit performs frequency hopping using a frequency band excluding the unusable frequency band.

Abstract: A downlink data frame addressed to a terminal is copied and obtained downlink data frames are transmitted through different APs, respectively. When a plurality of same uplink data frames are received through the different APs, any one uplink data frame selected out of the uplink data frames is transmitted to its destination. An uplink data frame received from the terminal is copied and obtained uplink data frames are transmitted through different STAs, respectively. When a plurality of same downlink data frames are received through different STAs, any one downlink data frame selected out of the downlink data frames is transmitted to the terminal.
