摘要： According to one embodiment, 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.

摘要： An apparatus includes a unit receiving a first-radio signal indicating a state in which transmission by a SDMA scheme is allowed, a unit determining whether a transmission state is a first state (the SDMA scheme is available), or a second state (the SDMA scheme is unavailable), a unit transmitting a radio signal using the SDMA scheme, when it is determined that the first state continues for the first-time period, and a unit setting a third-time period, when the first state fails to continue for the first-time period, the third-time period being obtained by subtracting, from the first-time period, a second-time period ranging from when carrier sense is started to when the transmission state is determined to be the second state, wherein when the first-radio signal is received after the third-time period is set, it is determined whether the first state continues for the third-time period.
