| 20100265828 | COMMUNICATION AND METHOD - A communication method according to the present invention includes receiving MAP in formation, acquiring an initial scheduled frame number and a current frame number from the MAP information, calculating the difference between the initial scheduled frame number and the current frame number, comparing the difference between the initial scheduled frame number and the current frame number with a reference value and setting a scheduled frame number, and performing transmission or reception in the scheduled frame. Therefore, even though a MAP loss occurs, the mobile station can receive only downlink data effective in downlink, thereby reducing power consumption for unnecessary reception, and can exactly perform transmission in a frame in which it should transmit in uplink. | 10-21-2010 |
| 20110063026 | PRE-DISTORTION APPARATUS OF POWER AMPLIFIER AND METHOD THEREOF - A pre-distortion apparatus of a power amplifier includes: a pre-distortion unit configured to generate a pre-distorted signal of an input signal by calculating a magnitude of the input signal and outputting a complex correction coefficient corresponding to the calculated magnitude of the input signal, and provide the generated pre-distorted signal as an input of the power amplifier; and a complex correct coefficient update unit configured to generate an error signal by comparing an output signal of the power amplifier with the input signal and updating the complex correction coefficient to minimize a magnitude of the generated error signal, wherein the pre-distortion unit provides a constant bias value corresponding to the magnitude of the input signal as a bias of the power amplifier while updating the complex correction coefficient. | 03-17-2011 |

| 20100069110 | METHOD OF CONTROLLING POWER OF ACCESS UPLINK USING RELAY STATION AND SYSTEM THEREOF - Provided are a method of controlling power of an access uplink using a relay station (RS) and a system thereof. When a base station (BS) decides that the subject of power control of the access uplink is itself, the BS generates a message for power control of the access uplink based on channel quality measurement information reported from the RS and transmits the power control message to a subscriber station (SS), and when the BS decides that the subject of power control of the access uplink is the RS, the RS generates a message for power control of the access uplink based on channel quality measurement information and transmits the power control message to the SS. Thus, fast power control of the access uplink can be performed. | 03-18-2010 |

| 20120025909 | DISTORTION COMPENSATION APPARATUS AND APPARATUS AND METHOD FOR TRANSMITTING SIGNAL - A distortion compensation apparatus and an apparatus and method for transmitting a signal are provided. The distortion compensation apparatus can extract precise distortion information by adding an additional signal to an input signal during the compensation of distortion in a nonlinear apparatus, and can linearize the nonlinear properties of the nonlinear apparatus using the distortion information. The apparatus for transmitting a signal can output a signal linearized by the same method as that used by the distortion compensation apparatus. | 02-02-2012 |
