| 20100322180 | METHOD FOR TRANSMITTING SCHEDULING INFORMATION IN MOBILE COMMUNICATION SYSTEM AND FEMTOCELL BASE STATION APPARATUS USING THE SAME - A method for transmitting scheduling information in a mobile communication system and a femtocell base station apparatus using the same are provided. Scheduling information can be transmitted using a hierarchical scheduling scheme in which a femtocell base station is allocated resources from a macrocell base station and the femtocell base station then allocates resources to femto users within its own resource region. | 12-23-2010 |
| 20110090945 | METHOD AND APPARATUS FOR COOPERATIVE MIMO TRANSMISSION OPERATION IN MULTICELL WIRELESS NETWORK - A method and apparatus of configuring a multi-cell precoding matrix for a multiple input multiple output (MIMO) operation in a wireless communication system in which a plurality of base stations participate in cooperative communication is provided. A multi-cell precoding matrix is configured using one or more single-cell precoding matrices, and wherein coefficients to be multiplied by the single-cell precoding matrices satisfy a condition in which the product between the multi-cell precoding matrix and a Hermitian matrix of the multi-cell precoding matrix is a unitary matrix. According to the embodiment of the present invention, it is not necessary for all base stations to perfectly know channel information. In addition, a feedback overhead is not high, and complexity is low. | 04-21-2011 |

The apparatus includes a voltage manager for determining whether the Tx power needs to be changed based on an output voltage that is based on a current that varies according to a distance between an electrode of a portable terminal and an electrode of a counterpart portable terminal, and changes the Tx power according to a result of the determination. | 12-03-2009 |
| 20100055815 | METHOD OF MANFUACTURING LENS FOR LIGHT EMITTING DIODE PACKAGE - The present invention relates to a method of manufacturing a lens for a light emitting diode package and can reduce a manufacture cost through reduction of material loss and improve productivity through a simple process without an additional device by freely implementing a final lens shape by curing liquid resin in multi-steps. | 03-04-2010 |
| 20100175407 | AIR CONDITIONER - An air conditioner includes a heat-exchanger positioned in an outdoor unit and configured to conduct heat-exchange between air provided from outside of the outdoor unit and a refrigerant. The air conditioner also includes a fan configured to generate a flow of the air that is from the heat-exchanger to an outlet of the outdoor unit. The air conditioner further includes a driving unit configured to provide a driving force to the fan. In addition, the air conditioner includes a first member positioned in the flow of the air generated by the fan and a second member configured to guide a flow of the air to reduce collision between the air and the first member when the fan is operated. | 07-15-2010 |
| 20100289673 | TERMINAL AND METHOD FOR EXECUTING FUNCTION USING HUMAN BODY COMMUNICATION - Provided is a method and a terminal for executing a function of a terminal according to data transmitted and received through a human body, which includes detecting a touch in a human body communication signal input unit, wherein the human body communication signal input unit is in a human body communication key mode; determining a number detected touches and determining a number pulse signals transmitted during a time in which the touch is maintained when the touch is detected; and executing a function corresponding to the human body communication signal. | 11-18-2010 |
| 20110001724 | COMMUNICATION TERMINAL FOR PERFORMING ELECTRIC FIELD COMMUNICATION AND METHOD FOR OPERATING THE SAME - An electric field communication terminal and a method for operating it are disclosed. Since the communication terminal according to the present invention includes a plurality of signal electrodes, it can perform electric field communication without contacting the user's body, which provides use convenience.
