  • Patent number: 10244431
    Abstract: A radio communication method stores a plurality MAC frames for each of a plurality of destinations. The method decides the longest transmission time of transmission times needed to transmit the plurality of MAC frames to each of the plurality of destinations within a fixed period. The method generates a plurality of physical frames for the plurality of destinations to transmit them at the same time by connecting the plurality of MAC frames and adding additional information to each connected MAC frame so as to be a frame length equivalent to a transmission time equal to the longest transmission time.

  • Patent number: 10154436
    Abstract: A physical frame is constructed, the physical frame including a medium access control super-frame payload which in turn includes a plurality of medium access control frames. With respect to the constructed physical frame, virtual carrier sense information is set in the plurality of medium access control frame so that a result of carrier sense is identical to another by virtual carrier sense based on the plurality of medium access control frames in the medium access control super-frame payload. The physical frame in which the virtual carrier sense information has been set is transmitted to a destined communication apparatus.

  • Patent number: 9648590
    Abstract: A communication device includes a receiver, a transmitter and an interruption module. The receiver receives an allocation signal indicating a first period usable by the communication device and a second period usable by a plurality of communication devices including the communication device. The transmitter transmits a transmission signal in the first period. If the transmission of the transmission signal is completed within the first period, the interruption module interrupts at least a part of power supply to the receiver in the second period. If the transmission of the transmission signal is not completed within the first period and directivity of radio waves used by a second communication device includes a direction of the communication device in a communication period allocated before the second period, the transmitter transmits the transmission signal in the second period.
