Abstract: A method for performing an operation for a first terminal in a wireless communication system, in one embodiment, comprises the steps of: determining, by the first terminal, a slot that is to transmit a physical uplink control channel (PUCCH), on the basis of a value for indicating the number of slots from a physical sidelink feedback channel (PSFCH) to the PUCCH; and transmitting, by the first terminal, PSFCH-based feedback information in the slot through the PUCCH to a base station, wherein the value for indicating, on the basis the slot for the PUCCH and the slot for the PSFCH not being synchronized with each other, the number of slots is a value corrected by the first terminal on the basis of a synchronization difference between the slot for the PUCCH and the slot for the PSFCH.

Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes transmitting a physical sidelink shared channel (PSSCH) to a second UE by the first UE, and transmitting, to a base station (BS), feedback information based on a physical sidelink feedback channel (PSFCH) for the PSSCH on a physical uplink control channel (PUCCH) by the first UE. A transmission timing of the PUCCH is determined based on information about the number of slots from the PSFCH to the PUCCH.

Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes determining a slot for transmitting a physical uplink control channel (PUCCH) based on a value related to the number of slots from a physical sidelink feedback channel (PSFCH) to the PUCCH by the first UE, and transmitting, to a base station (BS), feedback information based on the PSFCH through the PUCCH in the slot by the first UE. The value related to the number of slots is applied based on a last of slots for the PUCCH, overlapped with a slot for the PSFCH on a time axis.

Abstract: The present invention relates to an amorphous alloy having low frictional resistance and capable of improving abrasion resistance, a target made of the amorphous alloy, and a compressor comprising a layer of the amorphous alloy as a coating layer. According to the present invention, it is possible to secure high hardness and a low elastic modulus of the coating layer by controlling a microstructure having an amorphous phase as a primary phase by using Ti-based three-component to five-component amorphous alloys. As a result, it is possible to prevent the coating layer from being peeled off from a matrix or destroyed, and thus it is possible to achieve the effect of improving reliability or durability of a mechanical apparatus such as a compressor.

Abstract: A disclosure of the present specification provides a method for transmitting data by a transmitter. The method may comprise the steps of: when a transport block (TB) is divided into n data blocks, adding additional information after each of the n data blocks; and adding a cyclic redundancy check (CRC) after the last additional information. Here, the CRC may be generated on the basis of the n data blocks, and the n pieces of additional information added after each of data blocks.
