20090135778	Method and apparatus for scheduling in cellular system using cable relay station - A method for scheduling in a cellular system using a relay station (RS) through an inter-antenna cooperative transmission technology based on pre-cooperation information according to each channel in a cellular system using a cable RS in order to increase the throughput of the entire system. The steps include classifying all mobile stations (MSs) in a corresponding cell based into Cooperative Transmission (CT) MSs for cooperative transmission and Single Transmission (ST) MSs for to each channel; mapping channel-by-channel channel capacities of the CT MSs and ST MSs classified according to each channel, selecting a channel with a highest priority, and receiving a request message from a corresponding MS according to whether the capacity of the selected channel satisfies preset CT criteria and selecting an MS having a metric value of a highest priority according to a corresponding scheduling algorithm, from among multiple requesting MSs.	05-28-2009

20080205336	METHOD AND APPARATUS FOR JOINT SCHEDULING TO INCREASE FREQUENCY EFFICIENCY AND FAIRNESS IN A MULTI-CHANNEL DISTRIBUTED ANTENNA SYSTEM USING FREQUENCY REUSE AND COMMON POWER CONTROL - A joint scheduling apparatus and method for increasing frequency efficiency and fairness in a multi-channel distributed antenna system using frequency reuse and common control power. One of a Base Station (BS) or Relay Station (RS) are selected to transmit packets to a Mobile Station (MSs), taking into account Quality of Service (QoS) in one of a BS and an RS and grouped into packet groups. The packets are selected from the packet groups, links corresponding to the packets are grouped into a link group, a joint power control is performed on the link group, link elimination and link addition are performed for the link group until optimal solutions are achieved for the links group, channels are allocated to the links when the optimal solutions are achieved for the links, and the status of a user queue is updated.	08-28-2008

20090003704	METHOD AND SYSTEM FOR CONTROLLING BROWSER BY USING IMAGE - Browser controlling method and system using an image are provided. The method includes inputting an image; recognizing the image; and executing a command based on the recognized image. Accordingly, the command based on the user's input image can be executed in the browser. Also, since the browser does not need to display various function buttons, the screen can be utilized more efficiently.	01-01-2009
