According to one embodiment, a power control apparatus includes a calculation unit, a detection unit, a storage unit, a selection unit and an execution unit. The calculation unit calculates a spare power capacity and a total spare power capacity. The detection unit detects whether a required spare capacity is short, based on the required spare capacity and each of the spare power capacity and the total spare power capacity. The storage unit stores power control operation items. The selection unit selects power control operation items if the required spare capacity is short. The execution unit executes application operation of one or more the power control operation items until the required spare capacity becomes available, and executes waiting operation of one or more power control operation items executing the application operation if the required spare capacity is available.

A communication apparatus includes a first generation unit which sequentially generates image data in accordance with an event occurring due to a change in an operating state of an application program; a difference detecting unit which detects a difference between a plurality of consecutive image data generated by the first generation unit; a second generation unit which generates send data to be sent to the display terminal by compressing to the difference; a message generating unit which generates a message to change the spatial multiplexing number to either one or a plural number according to the change in the operating state of the application program or the difference; and a sending unit which sends the message to the wireless access apparatus prior to sending to the display terminal of the send data generated by the second generation unit.
摘要:
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.
