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 transmitting uplink (UL) data requiring low latency in a wireless communication system is disclosed. The method performed by a user equipment (UE) includes receiving a first control message for informing a basic Contention-based PUSCH (Physical Uplink Shared Channel) Zone (CP zone) allocated to each subframe from an enhanced Node B (eNB), receiving a second control message for informing changes in a CP zone allocated to a specific subframe from the eNB, and transmitting UL data to the eNB through a CPRB (Contention PUSCH Resource Block) of the changed CP zone based on the received second control message. The first control message includes basic CP zone resource information indicating resource information of the basic CP zone, and the second control message includes changed CP zone resource information indicating resource information of the changed CP zone.
