Abstract: An apparatus and method for performing uplink scheduling in a Multiple-Input Multiple-Output (MIMO) system are provided. The method includes selecting User Equipments (UEs) as members of at least one user set for simultaneous transmission from among UEs from which channel information is received, using the channel information, and generating a power control value for each of the at least one user set and transmitting the power control value to UEs of the user set. The at least one user set includes a second user set including UEs selected according to interference that the UEs cause to a first user set from among remaining UEs unselected for the first user set, the first user set including UEs selected in a descending order of reception power from among the UEs from which the channel information is received.

Abstract: A frequency-efficient antenna operation method is provided in a multiuser beamforming system. The method includes determining channel correlations and channel gain differences between channels using channel information received from multiple terminals, classifying the multiple terminals into at least one or more clusters using the channel correlations and channel gain differences, selecting a beamforming vector for each of the one or more clusters using the channel information of at least one or more terminals in the one or more clusters, allocating power to the terminals in each of the one or more clusters, and forming a beam based on the allocated power and the selected beamforming vector. According to the method, interference due to sharing space resources may be reduced and more efficient data communication may be achieved.

Abstract: A method and apparatus for charging a battery of a mobile device are provided. In the apparatus, a processor of the device starts a charging process when a connection of a charger is detected after a booting process of the device is initiated. The processor adjusts electric power by performing at least one of reducing consuming power of the device and raising charging power of the device. When a completion condition of a power adjustment is satisfied, the processor returns the electric power by performing at least one of returning the reduced consuming power to a basic consuming value and returning the raised charging power to a basic charging value.
