| 20110103289 | SYSTEM AND METHOD FOR EFFICIENT ENHANCED MULTICAST BROADCAST SYSTEM (E-MBS) CONFIGURATION MESSAGE DECODING - A base station comprises a transmitter configured to transmit a downlink frame. The downlink frame comprising a first configuration message associated with the configuration of Enhanced-Multicast Broadcast Service (E-MBS). The first configuration message comprises a field with an indicator to indicate a next configuration message to be decoded by a subscriber station. The subscriber station, upon decoding the first configuration message, refrains from decoding subsequent configuration messages that precede the next configuration message to be decoded by the subscriber station in accordance with the indicator. | 05-05-2011 |
| 20100210276 | MULTI-CELL NETWORK INCLUDING COMMUNICATION DEVICE SCHEDULING OUTER CELL FREQUENCY RESOURCE AND METHOD FOR SAME - A communication device, base station, terminal, and method for a multi-cell network include a scheduler configured to generate outer cell scheduling information by scheduling outer cell frequency resources for outer terminals in outer cells of a plurality of cells, and a scheduling information provider configured to provide the outer cell scheduling information to the plurality of cells. | 08-19-2010 |
| 20100096936 | VIBRATION MOTOR - A vibration motor includes a first resilient member and a second resilient member providing resilient forces in opposite directions; a first vibrator and a second vibrator coupled to the first resilient member and the second resilient member respectively; a magnetic body coupled to the first vibrator to create a magnetic field; and a coil applying a current of a predetermined frequency band in the region where the magnetic field is created. | 04-22-2010 |
| 20090242966 | Vertical-type semiconductor devices - In a vertical-type memory device and a method of manufacturing the vertical-type memory device, the vertical memory device includes an insulation layer pattern of a linear shape provided on a substrate, pillar-shaped single-crystalline semiconductor patterns provided on both sidewalls of the insulation layer pattern and transistors provided on a sidewall of each of the single-crystalline semiconductor patterns. The transistors are arranged in a vertical direction of the single-crystalline semiconductor pattern, and thus the memory device may be highly integrated. | 10-01-2009 |
| 20090238453 | Method of compressing a block-based binary image - A method of compressing a 2×2 block based binary image is provided. The method includes: determining whether pixels included in a block are included in existing patterns; generating the number N of the pixels included in the existing patterns (N is a natural number); when N is more than a predetermined value, compressing the block with a binary bit stream comprising information about patterns of the pixels included in the existing patterns and color information about the pixels having a new pattern. The method of compressing a 2×2 block based binary image reduces information damage which may occur during compression and restoration of the binary pattern so that the difference in picture quality between an original image and the restored image can be visibly improved. | 09-24-2009 |
| 20090108327 | Gate pattern having two control gates, flash memory including the gate pattern and methods of manufacturing and operating the same - Provided may be a gate pattern, flash memory and methods of manufacturing and operating the same. A gate pattern may include a floating gate on a tunneling dielectric layer, an inter-gate dielectric layer on the floating gate, a first control gate on the inter-gate dielectric layer, and a second control gate on the inter-gate dielectric layer and spaced apart from the first control gate. Each of the control gates sets four states according to an application time of a program voltage applied to the control gates. Thus, one control gate may program 2-bit data. | 04-30-2009 |
| 20080256527 | METHOD OF GENERATING FIRMWARE UPDATE FILE, METHOD AND APPARATUS FOR UPDATING FIRMWARE BY USING THE FIRMWARE UPDATE FILE - Provided are a method of generating a firmware update file which restrictively allows a firmware update for a corresponding hardware model, and a method and apparatus for updating firmware using the firmware update file. By generating a data body including program codes of firmware to be updated, generating a data header including model codes of a hardware device to which the data body is applied, and generating the firmware update file by combining the data body and the data header, the firmware update may be restricted for a corresponding model of a hardware device by using the firmware update file so that firmware of other models of hardware devices may not be updated, an integrity check may be performed using a digital signature when the firmware is updated. | 10-16-2008 |
| 20080248773 | APPARATUS AND METHOD FOR INTERFERENCE CANCELLATION IN multiple-antenna COMMUNICATION SYSTEM - An apparatus and method for interference cancellation in multiple-antenna communication system is disclosed. Accordingly, a receiver of a multiple-antenna communication system cancels interference by selecting either a multiple-symbol processing scheme or a single-symbol processing scheme depending on a signal type, thereby improving performance of the communication system. | 10-09-2008 |
| 20080212556 | APPARATUS AND METHOD FOR ALLOCATING RESOURCES IN A SINGLE CARRIER-FREQUENCY DIVISION MULTIPLE ACCESS SYSTEM - An apparatus and method for allocating resources in an Single Carrier-Frequency Division Multiple Access (SC-FDMA) communication system are provided, in which a Node B performs inter-subband hopping on a resource unit for a User Equipment (UE) on a frequency axis along which at least two subbands are defined, at each predetermined hopping time, determines whether to turn on or off mirroring in a subband having the hopped resource unit on a cell basis at the each hopping time, selects a resource unit by selectively mirroring the hopped unit according to the determination, and allocates the selected resource unit to the UE. | 09-04-2008 |
