Abstract: Provided are a method for transmitting a relay signal for V2X communication in a wireless communication system and a device using the same. Specifically, a terminal receives allocation information of a first relay resource and a second relay resource for a communication group from a base station. A first terminal receives a data signal through a reception beam for the first relay resource from a second terminal. The first terminal transfers the data signal to a third terminal through a transmission beam for the first relay resource. Further, the first terminal transmits an ACK/NACK for the data signal to the second terminal through a transmission beam for the second relay resource. The reception beam for the first relay resource is symmetrical to the transmission beam for the second relay resource. The transmission beam for the first relay resource is symmetrical to a reception beam for the second relay resource.

Abstract: Provided are a method and a device for transmitting data in a wireless communication system. More particularly, a terminal transmits a first transmission preamble and a second transmission preamble so as to estimate an uplink channel. If a common temporary identifier is assigned to the first and second transmission preambles, a common response message for the first and second transmission preambles is received. If temporary identifiers that are different from each other are respectively assigned to the first and second transmission preambles, respective individual response messages for the first and second transmission preambles are received. Data is transmitted by means of an estimated uplink channel. The first transmission preamble is transmitted in a plurality of resource regions, and the second transmission preamble is transmitted in one resource region.
