Abstract: Provided are a method and an apparatus for transmitting, on the basis of a repeating pattern, a synchronization signal in a wireless communication system. A base station divides a cell into multiple sectors and transmits multiple types of synchronization signals, which respectively correspond to the multiple sectors and have different repeating patterns, to a terminal through a system frame. The terminal performs detection of the multiple types of synchronization signals having the different repeating patterns and determines the position of the terminal within the cell according to the detected synchronization signals.

Abstract: The present invention relates to methods for interference cancellation between terminals in a full-duplex radio (FDR) system and apparatuses supporting the same. A method for cancelling interference between terminals in a wireless access system supporting a full-duplex radio (FDR) system, as an aspect of the present invention, may comprise the steps of: receiving, by a first terminal, reference signal information including information for configuring an interference reference signal from a base station; receiving the interference reference signal from a second terminal; obtaining, by the first terminal, interference channel information with regard to an interference channel between the first terminal and the second terminal on the basis of the interference reference signal; and transmitting by beamforming uplink data to the base station on the basis of the interference channel information by the first terminal. In this case, the first terminal is supported by the FDR system and the second terminal supports the half-duplex radio (HDR) system, and a resource area transmitting uplink data by the first terminal can be configured to match a resource area receiving downlink data by the second terminal.

Abstract: The present document is for a wireless communication using multiple antenna units based on new virtual user equipment (virtual UE) concept. A user equipment (UE), according to the present invention, receives service from a network in a wireless communication system by registering multiple antenna units of the UE as two or more virtual UEs with a first network entity of the network, wherein the first network entity is a network node for physical radio link control; and receiving the service from the network by the two or more virtual UEs. The two or more virtual UEs of the UE are recognized as one UE by network entities of the network other than the first network entity.

Abstract: The present invention, which is used in a wireless access system supporting device-to-device (D2D) communication, defines a new random access channel region and provides methods for obtaining synchronization between D2D devices in the new random access channel region, and devices supporting same. The method for obtaining synchronization between devices in a wireless access system supporting device-to-device (D2D) communication, according to one embodiment of the present invention, may comprise: a step in which a first terminal receives a D2D preamble from a second terminal via a D2D random access channel (RACH) region in an RACH region; a step in which the first terminal obtains synchronization with the second terminal by using the D2D preamble; and a step in which the first terminal performs D2D communication with the second terminal. The RACH region may comprise a legacy RACH region to which a legacy preamble for performing an RACH procedure with a base station is transmitted, and the D2D RACH region.
