According to one embodiment, a wireless communication device includes: a communicator and controlling circuitry. The communicator is configured to simultaneously communicate a first frame and a second frame, and after the first frame and the second frame are communicated, communicate a third frame indicating acknowledgement of the first frame and a fourth frame indicating acknowledgement of the second frame. The controlling circuitry is configured to control to prevent the third frame and the fourth frame from being simultaneously communicated.

Wireless communication device

To save power consumed due to reception of frames destined to other communication devices and enable power saving by prolonging a sleep state. A communication device is provided including a communication unit which communicates with a base station, a switching unit which switches an operation mode of the communication unit from a normal mode for communicating with the base station to a power saving mode for uncommunicating with the base station, when the communication unit receives data from the base station in a state in which the communication unit does not transmit a data transmission request to the base station, and a determination unit which determines a duration time of the power saving mode, based on a data length of the data received.

Communication control method and communication device for enabling power saving

There is provided a wireless communication control device and a wireless communication control method, which control the transmission power of radio waves of base stations appropriately to reduce interference between cells. The wireless communication control method according to the present invention is a method of controlling plural base stations in a wireless communication system in which the plural base stations cover a target area with radio waves of a first radio wave strength or more, the method causing a computer to execute: a step of acquiring a relative positional relationship of the plural base stations; a step of identifying a base station, located in the neighborhood of the boundary of the target area, from the relative positional relationship of the plural base stations; and a step of lowering the transmission power of radio waves of a base station other than the identified base station among the plural base stations.
