Abstract: The present invention relates to a device and method for transmitting control information for inter-heterogeneous cell interference adjustment in a wireless communication system. The present invention relates to a base station including: a signal receiving unit for receiving an ABS pattern; a system information generating unit for generating separation information that notifies the separated distance from a first sub frame transmitting PDCCH on the basis of the ABS pattern to a second sub frame transmitting PDSCH scheduled by the PDCCH; a downlink control information generating unit for generating downlink control information including a scheduling offset which indicates the separated distance; and a signal transmitting unit for transmitting the downlink control information from the first sub frame and transmitting a paging message or system information from the second sub frame.

Abstract: The present invention relates to a method and apparatus in which UE of an RRC_IDLE state which is near a femto cell (i.e., a Closed Subscriber Group (CSG) cell), but is not a CSG member requests a Base Station (BS) of a femto cell to apply Inter-Cell Interference Coordination (ICIC). In the present invention, the UE of an RRC_IDLE state selects a femto cell having a CSG ID not included in an allowed CSG list, transmits a Tracking Area Update (TAU) request message to a Mobility Management Entity (MME) managing the BS through the BS. Here, the TAU request message is a transfer request message requesting that a request to apply the ICIC be transferred to the BS of the CSG femto cell.

Abstract: The present description relates to a method and apparatus for transmitting channel state information in a wireless communication system. The method comprises the following steps: receiving, from a base station, information indicating a linkage between a cell set including a serving cell and a subset including a subframe; configuring channel state information for the subframe on the serving cell; receiving, from the base station, channel-state-information-request information indicating the cell set; and transmitting the channel state information to the base station. According to the present invention, channel state information, which varies as time elapses, may be accurately measured, and channel state information of the point in time desired by the base station may be provided.

Abstract: A method for recovery of residual actinide element from chloride molten salts that are formed after electro-refining and/or electro-winning of a spent nuclear fuel and include actinide elements and rare-earth elements is provided. The method comprises conducting electrolysis using a liquid cadmium cathode (LCC) in the chloride molten salt that is formed after electro-refining and/or electro-winning of a spent nuclear fuel and contains rare-earth elements and actinide elements; electro-depositing the actinide elements contained in the chloride molten salt on the LCC in order to reduce a concentration of the actinide elements; and adding a CdCl2 oxidant to the chloride molten salt containing the LCC-metal alloy in order to oxidize the rare-earth elements co-deposited on the LCC, thereby forming the rare-earth chlorides in the chloride molten salt.

Abstract: An idle channel scanning method and apparatus are provided. The method of scanning for an idle channel via a device communicating with a plurality of peripheral devices in the same frequency environment includes: allocating at least one of all frequency channels of the frequency environment to each peripheral device of the plurality of peripheral devices; requesting the plurality of peripheral devices a state of the frequency channels allocated to each peripheral device; and receiving information on the frequency channel state scanned by the plurality of peripheral devices in response to the request for the state of the frequency channels allocated.
