A wireless power transmission device and method are provided. An amount of power transmitted wirelessly by the wireless power transmission device may be controlled based on information to be transmitted by the wireless power transmission device, such that the information may be transmitted without using any additional device for information transmission. Additionally, an internal impedance of a terminal may be controlled based on information to be transmitted by the terminal, and a reflected wave of a transmission signal transmitted by the wireless power transmission device may be then controlled, such that the information may be transmitted without using any additional device for information transmission. Therefore, no further device may be desired, and thus a power consumption amount may be reduced, and there may be no need to match a communication part for information exchange with a transmission part for wireless power transmission.

A user scheduling and transmission power controlling method in a hierarchical-cell communication system or a multi-cell communication system, and a device to perform the methods, are provided. Interference may occur between various cells in the hierarchical-cell communication system or the multi-cell communication system, and the interference may be controlled by adjusting transmission power of various cells. The various cells may determine an optimal transmission power based on a cost of a corresponding transmission power. Also, the various cells may serve various users and may propose an optimal user scheduling method.

摘要:
An apparatus and method of facilitating cooperation within a cognitive radio communication system. The cooperation system facilitated in the communication system by another communication system. The apparatus include: a receiver to receive an uplink signal from a mobile station and a cooperation signal from a second communication system, wherein the cooperation signal is associated with the uplink signal; an evaluator to evaluate a contribution of the cooperation signal with respect to detection of the uplink signal; and a radio resource management unit to control an available radio resource for the second system according to the contribution of the cooperation signal.
摘要:
A wireless network using a network coding scheme is provided. The wireless network may include at least two source nodes, at least two destination nodes, and a relay node. The at least two source nodes may divide source messages into partial source messages, and transmit the partial source messages to the relay node. The relay node may generate a network-coded message using the network coding scheme. The at least two destination nodes may overhear the partial source messages using overhearing channels and obtain the source messages based on the received network-coded message.
摘要:
Provided is an apparatus and a method for transmitting power to electronic devices and of transmitting and receiving data. The method of transmitting power includes searching for a device to be charged located in an area, determining whether the found device needs charging, and transmitting power to the found device when the found device is determined to need charging. The apparatus may be mobile, and may travel towards or away from one or more devices based on whether the one or more devices need charging.
