Abstract: Disclosed in the present application is a method for a terminal to perform a handover in a wireless communication system. In particular, the method comprises the steps of: receiving a random access triggering signal from a serving cell; executing a random access procedure with a target cell on the basis of the random access triggering signal; receiving a downlink signal from the serving cell and transmitting an uplink signal to the target cell; receiving, from the serving cell, a message ordering a handover to the target cell; and transmitting, to the target cell, a predetermined message indicating the completed handover, on the basis of the message ordering a handover.

Abstract: The present invention relates to a method for allowing a terminal to perform a random access procedure in a wireless communication system and a device therefor. Specifically, the method for allowing a terminal to perform a random access procedure in a wireless communication system comprises the steps of: setting a first search space for a first downlink control channel and/or a second search space for a second downlink control channel according to control channel configuration information of a terminal; and detecting a downlink data channel by blind decoding the first search space and/or the second search space, wherein the first downlink control channel and the second downlink control channel are detected by using different indicators.

Abstract: A method for receiving a relay physical downlink control channel (R-PDCCH) at a relay in a wireless communication system is discussed. The method according to one embodiment includes receiving first control information for downlink scheduling in a first slot of a set of resource block (RB) pairs. The first control information includes allocation information on one or more resource units. The method according to the embodiment further includes monitoring second control information in a second slot of the set of RB pairs. If the R-PDCCH is assigned to the second slot of the set of RB pairs, the R-PDCCH is configured to carry control information for uplink scheduling.

Abstract: Disclosed is a method for allowing a terminal to transmit and receive signals to and/from a base station in a wireless communication system using a time division multiplexing method. Specifically, the method comprises the steps of: receiving a request signal for resetting into a second uplink/downlink setting while transmitting and receiving a signal according to a first uplink/downlink setting; terminating an uplink retransmission process associated with a specific uplink subframe when the use of the specific uplink subframe is changed into a downlink subframe according to the second uplink/downlink setting; and applying the second uplink/downlink setting at a specific time point to transmit and receive signals.
