Abstract: A base station device includes: a communication unit configured to communicate with a terminal device using a beam which is output in a specific direction; and a control unit. The control unit is configured to acquire a first communication traffic volume of communication with a first terminal device which is performed using a first beam, and control the communication unit such that the communication with the first terminal device is performed using a second beam different from the first beam based on the first communication traffic volume.

Abstract: In a terminal-to-terminal communication system, each of communication terminals performs time synchronization by means of time information contained in a GPS signal received from a GPS satellite, and, with reference to the synchronized time, sets a notification period for transmission and reception of a notification signal, such as a beacon signal. In the notification period, each terminal transmits a beacon signal to other terminals, with the beacon signal containing the information indicating the timing for signal transmission. Each terminal has a function of relaying the terminal-to-terminal communication that takes place between other terminals. Each terminal determines a relay station by sharing, among the terminals and through transmission and reception of beacon signal, information such as positional information and electric field strength information of each terminal.

Abstract: A UE, which is a mobile terminal, is capable of a device-to-device communication. The UE displays, on a display unit, an LTE antenna picto based on a reception level of a radio wave transmitted by a base station, and a D2D antenna picto based on a reception level of a radio wave transmitted by a UE over the device-to-device communication. According to the UE, the reception level of the radio wave in the device-to-device communication can be immediately confirmed, as well as a reception level of a radio wave in communication with the base station.
