1. A method for performing wireless communication by a first device, the method comprising:
receiving, from a base station through a first physical downlink control channel (PDCCH), a first downlink control information (DCI) including information related to a first physical uplink control channel (PUCCH) resource and information related to sidelink (SL) resource allocation;
transmitting, to a second device, a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) based on the information related to the SL resource allocation;
receiving, from the second device through a physical sidelink feedback channel (PSFCH) related to the PSSCH, SL hybrid automatic repeat request (HARQ) feedback;
receiving, from the base station through a second PDCCH, a second DCI including information related to a second PUCCH resource and information related to a downlink (DL) resource allocation;
receiving, from the base station, a physical downlink shared channel (PDSCH) related to the second PDCCH based on the information related to the DL resource allocation; and
transmitting, to the base station, at least one of the SL HARQ feedback or the HARQ feedback related to the PDSCH on at least one of the first PUCCH resource and the second PUCCH resource,
wherein the first PUCCH resource and the second PUCCH resource are overlapped in a time domain.
