    Abstract: A method for transmitting, by a first relay user equipment (UE), signals by considering interferences in a further enhancement D2D (FeD2D) environment comprises the steps of: calculating, by the first relay UE, a distance to a virtual remote user equipment (UE) located on a straight line between the first relay UE and a second relay UE; determining an allowable interference intensity for the virtual remote UE, on the basis of a predetermined target signal to interference and noise ratio (SINR) value for the virtual remote UE and an intensity of a received signal from the second relay UE of the virtual remote UE; determining a transmission power on the basis of the allowable interference intensity and the calculated distance; and comparing the determined transmission power with a minimum transmission power that satisfies the target SINR, wherein the virtual remote UE may be located at a threshold of a target range of the second relay UE.

    Abstract: A method and apparatus for a user equipment (UE) performing a random access to a network are disclosed. For this end, the UE selects a first carrier for the random access among multiple carriers, and transmits a first random access preamble for a first random access procedure via the first carrier to the network. Then, the UE applies backoff time to the first carrier and reselects a second carrier for the first random access procedure among the multiple carriers, when the first random access procedure is determined as not successful; and transmits a second random access preamble via the second carrier to the network. Here, reselecting the second carrier is performed before the backoff time applied to the first carrier ends.

    Abstract: The present invention discloses a method for reducing interference in a wireless communication system supporting D2D communication and an apparatus for the method. More specifically, in a wireless communication system supporting Device-to-Device (D2D) communication, a method for reducing interference in D2D communication comprises receiving, by a user equipment (UE), a D2D signal; determining, by the UE, whether interference is generated from resources in which the D2D signal has been transmitted; and in case it is determined that interference is generated from the resources in which the D2D signal has been transmitted, transmitting, by the UE, interference resource information for indicating that interference has been generated from the resources in which the D2D signal has been transmitted.

    Abstract: An embodiment relates to an operation method of a transmission (TX) UE related to sidelink DRX in a wireless communication system, the method comprising the steps in which: the TX UE establishes a PC5 connection with a reception (RX) UE; the TX UE receives a physical downlink control channel (PDCCH) including resource allocation information from a base station; and the TX UE transmits a sidelink signal through a resource based on the resource allocation information to the RX UE, wherein the TX UE performs initial transmission by using a resource related to retransmission on the basis that a resource related to the initial transmission does not overlap with an active time of the RX UE.

    Abstract: A method for performing wireless communication by a first device, and a device supporting same are provided. The method may comprise the steps of: acquiring at least one SL discontinuous reception (DRX) configuration; monitoring a message for establishment of unicast, on the basis of a first service identifier (ID); receiving the message for establishment of unicast from a second device, and establishing a unicast connection with the second device on the basis of the message for establishment of unicast, wherein, on the basis of the first service ID being related to a transmission profile indicating compatibility of SL DRX support, the message for establishment of unicast is monitored on the basis of a first SL DRX configuration.
