Abstract: Provided is a communication method for interference avoidance in an unlicensed band. A transmission node transmits in the unlicensed band a preemption signal to a target reception node. Upon receiving a ready signal from the target reception node, the transmission node transmits in the unlicensed band a data signal to the target reception node. The preemption signal is transmitted by means of a narrow beam having substantially the same width and direction as the data signal.

Abstract: This specification provides a long PUCCH using multiple slots in a wireless communication system. The method is performed by a user equipment and includes receiving first information about a TDD UL-DL slot configuration from a base station, receiving, from the base station, second information including a first parameter for a number of slots used for a transmission of the long PUCCH and a second parameter for a duration of a PUCCH symbol within a PUCCH slot, determining the multiple slots for transmitting the long PUCCH based on the first information and the second information, and transmitting the long PUCCH to the base station over the determined slots.

Abstract: Provided are a method of adjusting uplink timing in a wireless communication system and an apparatus therefor.Specifically, a method for a user equipment to adjust uplink timing in a wireless communication system includes transmitting, to a base station, an uplink signal, receiving, from the base station, a timing advance (TA) command configured based on the uplink signal, and performing uplink transmission to the base station by applying a timing advance (TA) indicated by the TA command. The TA command may be interpreted based on subcarrier spacing of at least one frequency resource region to which the TA is to be applied.

Abstract: Provided are a method of performing a random access procedure in an unlicensed band and a device using the method. The device performs a clear channel assessment (CCA) during a random access preamble (RAP) window in the unlicensed band. If the CCA succeeds, the wireless device transmits a plurality of RAPs. The plurality of RAPs are repeatedly transmitted in a frequency domain or a time domain.

Abstract: A hopping method for a terminal in vehicle-to-something (V2X) communication is disclosed. The terminal can perform hopping in a preset sized unit and allocate a remaining resource to a resource continuing to a hopped resource. When collision with a transmission resource of another terminal occurs after hopping, some transmission resources can be omitted on the basis of a hopping unit resource of a preset order and/or priority.

Abstract: The present invention relates to a method for efficiently transmitting and receiving a device to device (D2D) signal by utilizing relay user equipment (rUE) in a wireless access system supporting D2D communication. As one embodiment of the present invention, a method by which rUE efficiently relays a D2D signal in a wireless access system supporting D2D communication can comprises the steps of: receiving, from a base station, an upper layer signal including a reference value for measuring signal quality; measuring signal quality for at least one access link; selecting an access link to be relayed on the basis of the reference value; and relaying a D2D signal for the selected access link.

Abstract: The embodiments of the present invention relate to a wireless access system supporting an unlicensed band and to methods for generating a discovery signal (DRS), methods for generating and transmitting a channel state information reference signal included in the DRS, and devices for supporting same. The method for transmitting a discovery signal (DRS) including a channel state information reference signal (CSI-RS) in a wireless access system supporting an unlicensed band, according to one embodiment of the present invention, may comprise the steps of: initiating, in subframe n (SF #n), a listen-before-talk (LBT) procedure for checking whether the unlicensed band is idle or not; if an LBT procedure succeeds in SF #n+k, generating a sequence for transmitting the CSI-RS on the basis of the subframe index j indicating SF #j; and transmitting the DRS, including the CSI-RS, in SF #n+k. Herein n, k, and j are preferably integers greater than or equal to 0 and less than or equal to 9.
