    Abstract: Provided are a method and an apparatus for performing device-to-device (D2D) relay communication according to various embodiments. Disclosed are the method and the apparatus for performing device-to-device (D2D) relay communication, the method comprising the steps of: receiving a first signal that is beamformed and including counter information and a message, the counter information including at last one counter comparison value established for each direction and at least one counter value; and comparing the at least one counter comparison value established for mutually corresponding directions and the at least one counter value to determine at least one transmission direction, and beamforming a second signal for relaying the message for each of the at least one transmission direction and transmitting same, wherein the second signal includes the counter information in which a counter value corresponding to a transmission direction from among the at least one counter value is modified by a predetermined value, when transmitted in one direction among the at least one transmission direction.

    Abstract: Disclosed are a codebook-based uplink transmission method in a wireless communication system and a device therefor. Particularly, a method for a user equipment (UE) performing codebook-based uplink transmission in a wireless communication system includes the steps of: receiving from a base station downlink control information (DCI) for physical uplink shared channel (PUSCH) scheduling including precoding information and the number of layers; determining a precoder on the basis of the precoding information and the number of layers; and transmitting a PUSCH to which the determined precoder is applied to the base station, wherein the DCI may further include an amplitude coefficient and a phase coefficient applied to the precoder.

    Abstract: The present invention relates to a method for transmitting, by a terminal, a signal in a wireless communication system and an apparatus therefor. More particularly, the method comprises: a step of receiving a resource pool setting indicating a plurality of resource groups for transmitting and receiving, by a terminal, a signal from a first base station; and a step of transmitting a message by using a specific resource unit within a specific resource group among the plurality of resource groups according to the resource pool setting, depending on dynamic resource allocation information, wherein each of the plurality of resource groups is configured by successively allocating M resource units (where M is a natural number, M>0), in which each of the resource units is set for one of an uplink, a downlink, or a sidelink, and wherein the dynamic resource allocation information indicates that the message is to be transmitted through an N-th resource unit among the resource units within the specific resource group (where N is a natural number, M≥N>0).
