Abstract: A method and apparatus for transmitting ACK/NACK information in a wireless communication system are disclosed. In accordance with a method for transmitting ACK/NACK information, an ACK/NACK signal of downlink transmission in a downlink subframe set is transmitted in a single uplink subframe. In this case, if a first physical uplink control channel (PUCCH) format is established by a higher layer for a downlink receiver, and if one physical downlink shared channel (PDSCH) is transmitted in a downlink subframe set, the ACK/NACK information can be transmitted using a second PUCCH format on PUCCH resources established by a higher layer for the second PUCCH format.

Abstract: The present invention provides a method and apparatus for performing device-to-device communication in a wireless communication system. The method includes generating identification information of a D2D user equipment that supports the D2D communication as identification information for D2D discovery using a hash function, the identification information for discovery includes information of a first length for indicating a division region of the beacon signals and information of a second length included in the beacon. The information of a first length and the information of a second length are smaller than identification information of the D2D user equipment. Accordingly, by performing discovery for the D2D user equipment through the identification information having shorter length than prior art, and performing discovery in a range where the discovery is available through the region in which the beacon signals are allocated, advantages of performing the D2D discovery effectively are provided.

Abstract: A method and device for monitoring a control channel in a wireless communication system are provided. In particular, in consideration of multiple carrier aggregation, indication information is provided which includes information on a cell for monitoring a downlink control channel and information on a channel type defined to identify whether a downlink control channel to be transmitted from a corresponding cell is a legacy PDCCH (LPDCCH) or an enhanced PDCCH (EPDCCH). The indication information may be set in consideration of whether to arrange cross carrier scheduling. Thus, a terminal uses the indication information to adaptively monitor LPDCCH and/or EPDCCH through a predetermined search section of a corresponding cell. Thus, it is possible to adaptively schedule a downlink control channel and an enhanced downlink control channel.
