    Abstract: A method for performing, by a first device, wireless communication and an apparatus for supporting same are provided. The method includes: receiving a physical sidelink shared channel (PSSCH) from a second device; determining a physical sidelink feedback channel (PSFCH) resource associated with the PSSCH; and transmitting, to the second device, a hybrid automatic repeat request (HARQ) feedback on the PSFCH resource. Here, at least one subchannel for the PSSCH is associated with at least one first PSFCH resource including at least one second PSFCH resource, each second PSFCH resource included in the at least one first PSFCH resource is associated with each slot on the at least one subchannel, and the PSFCH resource may be determined on the basis of information related to the at least one subchannel for the PSSCH, information related to at least one slot for the PSSCH, and a source ID of the second device.

    Abstract: According to various embodiments, disclosed are a method by which a terminal simultaneously transmits messages in at least two carriers in a wireless communication system supporting device to device (D2D) communication, and an apparatus therefor. Particularly, disclosed are a method by which a terminal simultaneously transmits messages in at least two carriers, and an apparatus therefor, the method comprising the steps of: independently sensing, by a carrier, a transmission resource, and calculating the ratio of transmission resources, which can be simultaneously transmitted on at least two carriers, on the basis of a result of the sensing by the carrier; setting the sensed transmittable transmission resource as a transmission candidate resource when the calculated transmission resource ratio is greater than or equal to a preset threshold ratio; and selecting a transmission resource to be used for the message transmission in each of at least two carriers within the transmission candidate resource.

    Abstract: Provided are a method, performed by a first terminal, for adjusting a threshold for determining hybrid automatic repeat request (HARQ) feedback in a wireless communication system, and an apparatus for supporting the same. The method comprises the steps of: transmitting at least one piece of information to a second terminal; receiving, from the second terminal, at least one HARQ feedback in response to the at least one piece of information; determining an ACK or NACK with respect to the at least one HARQ feedback, based on the threshold; receiving, from the second terminal, an HARQ feedback transmission history of the second terminal; and adjusting the threshold, based on the HARQ feedback transmission history of the second terminal and information about the HARQ feedback determined by the first terminal.
