20080198837 | System and method for transmitting and receiving signal in communication system - Disclosed is a method for transmitting and receiving a signal in a communication system, and a system for supporting the method. To this end, a first communication system transmits data during a first time slot and receives data during a third time slot, and a second communication system, differing from the first communication system, transmits data during a second time slot and receives data during a fourth time slot. The first and second time slots are defined by downlink frame transmission intervals which exist in the entire frame transmission interval allocated for the first communication system, and the third and fourth time slots are defined by uplink frame transmission intervals which exist in the entire frame transmission interval allocated for the first communication system, wherein the first to fourth time slots do not overlap each other. | 08-21-2008 |
20080205338 | METHOD AND APPARATUS FOR ALLOCATING RESOURCES IN COMMUNICATION SYSTEMS - A resource allocation method and apparatus in a communication system having backward compatibility are provided. In a transmission apparatus, a determiner determines a first frequency band for transmitting wireless resource allocation information to a terminal from among the frequency bands supporting the communication system, a MAP generator determines at least one second frequency band over which the terminal desires to receive a service and allocates wireless resources to the second frequency band, and a transmission unit transmits the wireless resource allocation information to the terminal over the first frequency band. In a reception apparatus, a reception unit receives wireless resource allocation information over a first frequency band determined by a base station and a MAP information decrypter determines at least one service frequency band included in the wireless resource allocation information. Accordingly, the method and apparatus dynamically allocate wireless resources to a terminal when multiple systems having backward compatibility coexist. | 08-28-2008 |
20080205369 | APPARATUS AND METHOD FOR POWER DISTRIBUTION BY FREQUENCY ALLOCATION IN MULTI-FREQUENCY ALLOCATION BROADBAND WIRELESS COMMUNICATION SYSTEM - An apparatus and method for power distribution by Frequency Allocation (FA) in a multi-band broadband wireless communication system are provided. The method includes detecting at least one of a loading value and a performance efficiency value by band, calculating a power distribution value by band using the detected value and calculating a power value by band using the calculated band power distribution value. The method and apparatus provide a scheme that can vary a power distribution of each band according to need and cope with subscriber capacity more flexibly when a plurality of diverse systems coexist. | 08-28-2008 |
20080207214 | Apparatus and method for allocating uplink radio resource in wideband wireless communication system - An apparatus and method for UpLink (UL) radio resource allocation in a wideband wireless communication system are provided. In a method of operating a Relay Station (RS) for UpLink (UL) radio resource allocation in a wideband wireless communication system, the method includes relaying to a Base Station (BS) a resource request message of at least one or more Mobile Stations (MSs); receiving data from the at least one or more mobile stations; if the received data is non-real time traffic, queuing the data received from the mobile stations according to a traffic type; and requesting the base station to allocate necessary radio resources by checking a queue status. Accordingly, a delay can be reduced when the UL resource is allocated to an relay station for real time traffic. | 08-28-2008 |
20090103569 | SYSTEM AND METHOD FOR TRANSMITTING/RECEIVING SIGNAL IN A COMMUNICATION SYSTEM - A system and method for transmitting/receiving a signal in a communication system are provided, in which a transmitter determines to change a transmission time of a superframe header, when a structure of a superframe is changed, determines the transmission time of the superframe header according to a result of the determination to change the transmission time of the superframe header, transmits information about the determined transmission time to a receiver, and transmits the superframe header at the determined transmission time. | 04-23-2009 |
20090111376 | APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA IN A COMMUNICATION SYSTEM - An apparatus and method for transmitting and receiving data in a communication system are provided. In the method, a BS selects a repeater group from among a plurality of repeater groups, for use in transmitting first data to an MS and transmits the first data to the MS according to the number of repeaters of the selected repeater group. The first data is different from data transmitted by the repeaters of the selected repeater group. | 04-30-2009 |
20090113273 | APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING DATA RESTORATION INFORMATION IN A COMMUNICATION SYSTEM - An apparatus and method for transmitting data restoration information in a communication system are provided, in which a BS transmits first data in a first zone of a frame, transmits second data in a second zone of the frame, transmits first data restoration information for restoring the first data in the first zone, and transmits second data restoration information for restoring the second data in the second zone. The first data comprises the same data as data transmitted simultaneously by at least one repeater and the second data comprises data that is different from data transmitted by the at least one repeater. | 04-30-2009 |
20110199828 | NONVOLATILE MEMORY DEVICE AND METHOD OF OPERATING SAME - A nonvolatile memory device comprises a bulk region and a plurality of memory cells connected to a source line and a plurality of wordlines. The method comprises applying a source line voltage to the source line with a first magnitude, applying a bulk voltage to the bulk region with a second magnitude lower than the first magnitude, and performing access operations on the plurality of memory cells while maintaining a substantially constant difference between the bulk voltage and the source line voltage. | 08-18-2011 |
20120246586 | MOBILE TERMINAL AND OBJECT CHANGE SUPPORT METHOD FOR THE SAME - A mobile terminal and a method of supporting an object change for the same are provided. The mobile terminal includes a display unit for outputting at least one object, and a control unit for controlling at least one of directly displaying, in response to a signal for changing the output object into a second object having a similar function but being of a different type than the output object, the second object on the display unit without a screen transition, and for outputting, in response to a signal for changing the output object into a second object having a similar function but being of a different type than the output object, a guide frame on the display unit so as to facilitate change of the output object without a screen transition. | 09-27-2012 |
20130212520 | APPARATUS AND METHOD FOR EDITING IMAGE IN PORTABLE TERMINAL - An apparatus and a method for editing an image in a portable terminal which can conveniently edit the image are provided. The apparatus for editing the image includes a touch screen unit for displaying an image, and a controller for controlling such that, when one or more edit points are selected from edit points displayed in the image in an image edit mode, an edit function window for editing the selected one or more edit points is displayed. | 08-15-2013 |
