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.

According to an embodiment, a charge-discharge control device includes a receiving unit, a selecting unit, and a group controller. The receiving unit receives feasibility information. The selecting unit selects, of electric power devices that send the feasibility information indicating disallowance of simultaneously belonging to a plurality of charging groups, one electric power device as a representative device of the charging group to which belongs that electric power device; and selects, of electric power devices that send the feasibility information indicating disallowance of simultaneously belonging to a plurality of discharging groups, one electric power device as a representative device of the discharging group to which belongs that electric power device. Via the selected representative device, the group controller controls the other electric power devices belonging to the charging group or the discharging group to which belongs the selected representative device.
