An operating method of a wireless communication device performing an interference whitening operation includes obtaining first channel state information of the wireless communication device, selecting a selected mode from among a plurality of modes related to the interference whitening operation, the selected mode corresponding to the first channel state information, obtaining channel performance information according to the selected mode, and updating a value function expected value based on the first channel state information, the selected mode, and the channel performance information.

Wireless communication device for performing interference whitening operation and operating method thereof

An apparatus for transferring a wafer includes a main body, a first support installed in the main body, a sensor support fixed to the first support, a finger member slidably installed along the first support to transfer the wafer and positioned at a lower level than the sensor support, three sensors each including a light emitter installed on the first support and a light receiver installed on the sensor support, the three sensors respectively configured to detect three points of an edge of the wafer seated on the finger member, and a controller connected to the three sensors, wherein the controller is configured to determine whether any of the three points of the edge of the wafer is detected from a notch of the wafer based on signals received from the sensors.

Apparatus for transferring wafer, method for transferring wafer using the same with three sensors

The present invention relates to a method and a device for reducing the power of a device in a wireless communication system supporting direct device to device (D2D) communication. A method, for transmitting a signal of a device in a wireless communication system supporting direct D2D communication according to the present invention, comprises the steps of: entering sleep mode in direct D2D communication between a device and an opponent device; if data to be transmitted to the opponent device is generated, transmitting a paging signal for the opponent device to a base station connected to the device, thereby requesting transmission of the paging signal to the opponent device; and resuming the D2D communication with the opponent device that has received the paging signal through the base station.
