摘要： A light emitting diode and a method for fabricating the same are provided. The light emitting diode includes: a transparent substrate; a semiconductor material layer formed on the top surface of a substrate with an active layer generating light; and a fluorescent layer formed on the back surface of the substrate with controlled varied thicknesses. The ratio of light whose wavelength is shifted while propagating through the fluorescent layer and the original light generated in the active layer can be controlled by adjusting the thickness of the fluorescent layer, to emit desirable homogeneous white light from the light emitting diode.

摘要： An apparatus and a method for transmitting uplink feedback data in a broadband wireless mobile communication are provided. The method comprises dividing tiles used as a feedback channel into a preset number of groups, selecting one group among the preset number of groups using a downlink channel, selecting a number of tiles, the number of tiles being equal to a number of tiles required for feedback data transmission in the selected group, and mapping feedback data to each selected tile. Thereby, feedback information can be transmitted via a tile selected by a terminal based on a channel state without a process of allocating and reallocating an additional feedback channel, thus enhancing efficiency of uplink wireless resources.

摘要： An apparatus and method for transmitting and receiving Channel Quality Information (CQI) in a communication system. A Base Station (BS) transmits, to a Subscriber Station (SS), a request for CQI of a resource region corresponding to a frequency reuse factor K, which is designated by the BS. The BS then receives, from the SS, the CQI of the resource region corresponding to a channel quality measured by the SS. The channel quality is measured by the SS by measuring a boosted reference signal and compensating the boosted reference signal for a non-boosted signal.
