Abstract: A method for managing a NAV (network allocation vector) by a station (STA) in a wireless communication LAN system according to an embodiment of the present invention comprises the steps of: receiving a frame including duration information; and changing a NAV timer of the STA on the basis of the duration information of the frame. When an event occurs for a reset of the NAV timer, the STA may determine whether to reset the NAV timer in consideration of the remaining time that existed in the NAV timer right before the NAV timer was changed.

Abstract: Provided are a method for allocating a temporary radio network temporary identifier to a terminal within a random access procedure in a wireless communication system, and an apparatus supporting the same. The method for allocating a temporary radio network temporary identifier (T-RNTI) to a user equipment (UE) within a random access procedure in a wireless communication system, includes transmitting, by the UE, a random access preamble to a base station (BS), transmitting, by the UE, a radio resource control (RRC) request message to the BS through a contention-based physical uplink shared channel (PUSCH) resource block in which uplink data can be transmitted without uplink resource allocation scheduling, and receiving, by the UE, an RRC connection setup message identified by a T-RNTI allocated to the UE in response to the RRC request message, wherein the T-RNTI is allocated on the basis of the contention-based PUSCH resource block in which the RRC request message has been transmitted.

Abstract: The present invention relates to a structure of a full duplex radio (FDR) region in an FDR system. Further, the present invention provides a method and apparatuses for transmitting allocation information on a configured FDR region. In an embodiment of the present invention, a method of allocating an FDR region by a base station in a radio access system supporting an FDR scheme comprises the steps of: transmitting a control signal including FDR region allocation information to a terminal and performing FDR-based communication with the terminal through an FDR region indicated by the FDR region allocation information. At this time, the FDR region allocation information may contain one or more of first number information indicating a number of subcarriers included in the FDR region, position information indicating an allocation position of the FDR region, and second number information indicating a number of subcarriers included in a guard region used for reducing interference.
