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.

摘要： According to one embodiment, a wireless communication apparatus includes a determination unit, a first setting unit, a second setting unit and a wireless unit. The determination unit determines whether a signal degradation degree is higher than a threshold value. The first setting unit sets first parameters relating to a first data rate and a first communication robustness. The second setting unit sets second parameters relating to a second data rate and a second communication robustness if an instruction signal is received and if the signal degradation degree is higher than the threshold value. The wireless unit communicates with a communication partner using one of the first parameters and the second parameters.

摘要： An interface control device includes a first interface, a second interface, a third interface, an interface controller and a clock supplying unit. The first interface is used to communicate with a first information processing device and obtain a first clock signal from the first information processing device. The second interface is used to communicate using a second clock signal with a second information processing device different from the first information processing device. The third interface is used to communicate with a controller of a data-storage medium. The interface controller performs an interface control for the first, second and third interfaces. Moreover, the clock supplying unit supplies the first clock signal to the third interface while communications through the second interface have not been established.
