Abstract: A method is presented for a mobile station operating in a wireless communication system. The mobile station receives configuration information for power management from a base station. The configuration information informs the mobile station a first time period during which the mobile station monitors signals from the base station and a second time period during which the mobile station does not monitor signals from the base station. The mobile station applies the configuration information for power management to one or more primary carriers and one or more activated secondary carriers. The mobile station receives downlink data from the base station via the one or more primary carriers and the one or more activated secondary carriers during the first time period. The mobile station receives a specific Medium Access Control (MAC) message from the base station, wherein the mobile station stops the first time period when receiving the specific MAC message.

Abstract: Disclosed are a D2D communication method and device on the basis of a hopping sequence. A D2D communication method on the basis of a hopping sequence may comprise the steps of: obtaining information on a reference hopping sequence by a terminal wherein the reference hopping sequence is a current hopping sequence of a target terminal which will perform first D2D communication on the basis of a first link with the terminal; determining a final hopping sequence for performing the first D2D communication by the terminal on the basis of whether the terminal is an initial access terminal or a multi-access terminal and whether the current hopping sequence of the terminal is the same as at least one of communicable hopping sequences corresponding to a reference sequence and the reference hopping sequence; and performing the first D2D communication by the terminal on the basis of the final hopping sequence.

Abstract: The present invention relates to a wireless communication system, and more particularly, to a method and apparatus for transceiving a downlink control channel. According to one embodiment of the present invention, a method in which a base station transmits a downlink control channel to a terminal in a wireless communication system comprises the steps of: transmitting one or more enhanced-physical downlink control channels (E-PDCCHs) within a resource region allocable for an E-PDCCH; and transmitting E-PDCCH allocation resource information for the one or more E-PDCCHs to the terminal. The E-PDCCH allocation resource information indicates the resource in which the one or more E-PDCCHs exist from among the resource region allocable to the E-PDCCH. An effective physical downlink shared channel (PDSCH) allocation resource region for the terminal can be determined on the basis of the E-PDCCH allocation resource information.
