| 20100272043 | METHOD AND APPARATUS FOR TRANSMITTING RANGING CHANNEL IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for transmitting a ranging channel in a wireless communication system is provided. A mobile station (MS) receives frequency resource allocation information of a ranging channel and allocates the ranging channel to one ranging subband on a frequency domain determined based on the frequency resource allocation information of the ranging channel. The MS transmits the ranging channel. The frequency resource allocation information of the ranging channel includes a cell identifier (ID) of a cell and the number of allocated subbands or the number of allocated subband contiguous resource units (CRUs). | 10-28-2010 |
| 20110249634 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING UPLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM - A method and apparatus for transmitting and receiving uplink control information in a wireless communication system are disclosed. A method for receiving uplink control information from a base station in a wireless communication system includes the steps of allocating resources for transmitting uplink control information, transmitting resource allocation information of the resources, and receiving uplink control information from at least one user equipment through the resources. Herein, the resources are multiplexed so that a single PUCCH format can be used by a plurality of user equipments, a plurality of information, or a plurality of random access opportunities by enabling the plurality of user equipments, the plurality of information, or the plurality of random access opportunities to use different constellations each other. | 10-13-2011 |

| 20100119000 | METHOD AND APPARATUS FOR ADJUSTING POWER CONTROL MODE IN WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for adjusting power control mode in a wireless communication system is provided. A mode change message is transmitted from a base station (BS) to a user equipment (UE) to request changing a power control mode from a base station (BS). The mode change message comprises a power control mode change (PMC) field which indicates the power control mode to be changed. The UE transmits a UE confirmation message to the BS, and receives a BS confirmation message from the BS. The UE changes the power control mode based on the mode change message. | 05-13-2010 |

| 20100015511 | High Capacity Battery Cell Employed with Two or More Unit Cells - Disclosed herein is a secondary battery including two or more stacking-folding type cells (‘unit cells’) manufactured by winding small-sized electrode assemblies (‘bicells’) constructed in a stacking type structure in which electrodes having the same polarity are located at opposite sides of each electrode assembly and small-sized electrode assemblies (‘full cells’) constructed in a stacking type structure in which electrodes having different polarities are located at opposite sides of each electrode assembly using a long separator sheet, wherein the unit cells are mounted in a battery case, each unit cell has one or more electrode terminals protruding from each end of each unit cell, and the unit cells are mounted in a receiving part of the battery case such that the unit cells are arranged in a stacking arrangement structure or a plane arrangement structure while the electrode terminals of the unit cells are connected with each other. According to the present invention, the electrical and physical coupling force between the unit cells is increased. Consequently, the high-capacity secondary battery according to the present invention exhibits an improved structural stability. In addition, it is possible to greatly increase the capacity of the secondary battery according to the present invention through a simple assembly process. | 01-21-2010 |
| 20100021821 | Secondary Battery Having Electrode for Improvement of Stability During Overcharge - Disclosed herein is a secondary battery including an electrode assembly that can be charged and discharged, wherein the electrode assembly includes an electrode (‘safety electrode’) composed of a material that effects an electrochemical reaction when the secondary battery is overcharged (Overcharge reaction material’). The safety electrode according to the present invention is not directly added to components related to the operation of the secondary battery. Consequently, the safety electrode does not deteriorate the performance of the battery during the normal operation of the battery, and the safety electrode consumes the overcharge current through the electrochemical reaction, when the battery is overcharged, whereby the safety of the battery is fundamentally secured. | 01-28-2010 |
| 20110104527 | SECONDARY BATTERY HAVING SEALING PORTION OF NOVEL STRUCTURE - Disclosed herein is a plate-shaped secondary battery constructed in a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case, and the battery case is sealed by thermal welding, wherein the battery case is provided at a sealing portion around an electrode assembly receiving part thereof with an exhaust guide sealing portion configured in a structure in which a width of the exhaust guide sealing portion decreases from an inside of the sealing portion toward an outside of the sealing portion such that a sealing force of the exhaust guide sealing portion is first released, when high-pressure gas is generated in a battery cell, and therefore, the high-pressure gas is exhausted outside, the exhaust guide sealing portion being thermally welded with a sealing force less than that of a sealing portion located at a remaining region (‘a remaining sealing portion’), and the battery case is further provided at a middle of the exhaust guide sealing portion with a bridge sealing portion extending in parallel to the electrode assembly for interconnecting opposite sides of the remaining sealing portion with a predetermined width, the bridge sealing portion being thermally welded with a sealing force greater than that of the exhaust guide sealing portion. | 05-05-2011 |
