Abstract: According to an embodiment, a communication device is provided in a movable body and is wirelessly communicable with a transceiver unit and another movable body. The communication device includes a transmitter, a receiver, a synchronization unit, a registration unit, and a stop control unit. The transmitter transmits movable body information on the movable body to a predetermined channel. The receiver receives transceiver unit information that the transceiver unit has transmitted to the predetermined channel. The synchronization unit performs synchronization of reception timing when the transceiver unit information can be received. The registration unit registers a communication area of the transceiver unit calculated based on a position where the other movable body receives the transceiver unit information in storage. The stop control unit stops transmission of the movable body information at a reception timing of the transceiver unit information, when a position of the movable body is within the registered communication area.

Abstract: According to one embodiment, a wireless communication apparatus includes a transceiver, an estimator and a controller. The transceiver transmits and receives a frame in a frequency band which is used by a first system executing communication in a first communication range determined by a first transmission power and a first antenna gain. The estimator determines whether an amount of interference in the frequency band from a second system is no less than a threshold, the second system executing communication in a second communication range which is larger than the first communication range and which is determined by a second transmission power and a second antenna gain. The controller increases a transmission power when the amount of interference is no less than the threshold.

Abstract: According to an embodiment, a communication device is provided in a movable body and is wirelessly communicable with a transceiver unit and another movable body. A receiver of the device receives transceiver unit information including traffic-light information that the transceiver unit has transmitted to a predetermined channel. An processing circuitry extracts the traffic-light information corresponding to a running direction of the movable body from the transceiver unit information. A transmitter transmits movable body information of the movable body to the predetermined channel. A processing circuitry controls a transmission timing of the movable body information such that a transmission control period becomes a preset first time. A processing circuitry changes the transmission control period to a second time longer than the first time, when the traffic-light information with respect to the running direction indicates a stopping command, and a speed of the movable body is a preset speed or less.

Abstract: According to one embodiment, a wireless base station includes a transmitter and a receiver. The transmitter transmits a control signal and one or more operation signals to the second wireless communication terminal. The control signal instructs to transmit a signal that requests terminal-to-terminal communication between a first wireless communication terminal and the second wireless communication terminal. The operation signals are used for operating at least a part of the first wireless communication terminal. The receiver is capable of receiving at least one of a response signal or a data signal transmitted from the first wireless communication terminal to the second wireless communication terminal after the operation signals are transmitted.
