| 20100002643 | APPARATUS AND METHOD FOR INTER-CELL INTERFERENCE CANCELLATION IN MIMO WIRELESS COMMUNICATION SYSTEM - A method for operating a Mobile Station (MS) in a Multiple Input Multiple Output (MIMO) wireless communication system is provided. The method includes measuring channel quality for a serving Base Station (BS), if the channel quality is less than a threshold, measuring interference power from one or more neighbor BSs, determining a Precoding Matrix Index (PMI) and a priority metric for each neighbor BS, and feeding back at least one of the PMI, a PMI type indicator, the priority metric, and the channel quality to the serving BS. | 01-07-2010 |
| 20100061395 | SELF-ORGANIZING RESOURCE ACCESS APPARATUS AND METHOD IN LOCAL AREA NETWORK COMMUNICATION ENVIRONMENT - A self-organizing resource access method is provided for transmitting data by self-organizing resource access by each individual node in a Local Area Network (LAN) communication environment where at least two nodes exchange data with each other. A first node listens to at least one data transmission of at least one other node connected to the LAN, and adjusts a data transmission start time of the first node in accordance with a data transmission start time of the at least one other node so that the data transmission start time of the first node does not overlap the data transmission start time of the at least one other node. The first node transmits data to the at least one other node at the adjusted data transmission start time. | 03-11-2010 |
| 20100092152 | METHOD FOR OPERATING ADDTIONAL INFORMATION OF VIDEO USING VISIBLE LIGHT COMMUNICATION AND APPARATUS FOR THE SAME - A method for operating additional information related to video displayed on a display device by a terminal apparatus communicable with the display device, includes receiving first data related to the video from the display device, displaying information included in the first data on a built-in display and receiving at least one of the displayed information, which is selected by a user, generating an additional information request message for requesting the information selected by the user, sending the additional information request message to the display device, receiving from the display device second data including additional information corresponding to the additional information request message, and displaying the second data on the built-in display. | 04-15-2010 |
| 20110221389 | WIRELESS POWER CHARGING METHOD AND APPARATUS FOR ELECTRONIC DEVICE - A bidirectional wireless charging method includes performing a mode change to a requesting electronic device if charging is necessary, requesting charging from at least one electronic device, receiving status information from the at least one electronic device that has received the charging request, selecting the electronic device based on the status information, and performing charging by receiving power supplied from the selected at least one electronic device. | 09-15-2011 |
| 20110221390 | WIRELESS POWER CHARGING METHOD AND APPARATUS - A wireless charging method and apparatus wirelessly charges power between separate electronic appliances. The wireless charging method includes searching for at least one chargeable electronic device, receiving status information from the searched at least one electronic device, determining whether the electronic device is a power supply electronic device or a power demand electronic device, receiving a supply of power from the searched at least one electronic device if the electronic device is determined to be the power demand electronic device, and supplying the power to the at least one electronic device if the electronic device is determined to be the power supply electronic device. | 09-15-2011 |
| 20110221391 | METHOD FOR WIRELESS CHARGING USING COMMUNICATION NETWORK - A method for wireless charging of an electronic apparatus includes: requesting a server for information regarding chargeable electronic devices; receiving the information regarding chargeable electronic devices from the server; and performing charging with at least one electronic device. | 09-15-2011 |
| 20110225073 | APPARATUS AND METHOD FOR PERFORMING WIRELESS CHARGING - A wireless charging method includes searching one or more rechargeable electronic devices, receiving power service information from one or more searched electronic devices, determining whether the one or more searched electronic devices are rechargeable based on the received power service information, and if the one or more searched electronic devices are rechargeable, receiving power from the electronic devices. | 09-15-2011 |
| 20120033565 | NON-ACCESS STRATUM PROTOCOL OPERATION SUPPORTING METHOD IN A MOBILE TELECOMMUNICATION SYSTEM, AND THE SYSTEM THEREOF - The present invention relates to a method and system for management of the mobility of a terminal by using a non-access stratum (network stratum “NAS”) protocol in a mobile telecommunication network. The method for management of the mobility of a terminal by using an NAS protocol, i.e., messages includes a terminal (“UE”) and a mobile management entity (“MME”), and efficiently divides and processes security protected NAS messages and NAS messages with no security, and efficiently divides and processes EMM (EPS Mobility Management) messages, i.e., mobility management messages, and ESM (Evolved Session Management) messages, i.e., session management messages in a network such as an EPS (Evolved Packet System) of 3GPP, thereby managing the mobility and the sessions of a terminal in an efficient manner. | 02-09-2012 |
