Abstract: A method for performing a Full-Duplex Radio (FDR) operation in a wireless communication system that supports the FDR is disclosed. The method includes exchanging FDR capability information that represents whether to have a capability of performing the FDR operation between a user equipment (UE) and a base station (BS); receiving, by the UE, Inter-Device-Interference (IDI) measurement configuration information from the BS; performing, by the UE, an IDI measurement based on the received IDI measurement configuration information; reporting, by the UE, a result of the IDI measurement to the BS; and receiving, by the UE, a control message notifying that the UE is included in a group related to the FDR operation from the BS, where the FDR capability information includes indication information that represents whether to support an FDR mode that transmission and reception operations are available to be performed simultaneously using an identical radio resource.

Abstract: The present invention relates to a wireless access system supporting a full duplex radio (FDR) transmission environment. A resource allocation method of a base station in a wireless access system that supports a FDR, according to one embodiment of the present invention, comprises the steps of: transmitting a first frame setting for a configuration of an uplink subframe and a downlink subframe to a terminal which is set by a terminal-specific TDD; receiving, from the terminal, response information including traffic information of the terminal and/or frame setting information preferred by the terminal; and transmitting a second frame setting which has adjusted the ratios of the uplink subframe and the downlink subframe on the basis of the response information, wherein the second frame setting is capable of being set by shifting the first frame setting on the basis of the number of FDR interference terminals which simultaneously transmit an uplink.

Abstract: A method for and apparatus for performing handover in a wireless communication system is provided. A wireless device transmits measurement results configured for a secondary radio access technologies (RAT) system, receives information on routing modification based on the measurement results, from a network entity of a primary RAT system and performs a handover to a target access network according to the information on routing modification. The secondary RAT system is used for a user plane (U-plane) data, and the handover is determined based on at least one of a quality of service (QoS) information, load information about the primary RAT system and secondary RAT system, and a network preference information of the UE.
