1. A method for performing wireless communication by a first device, the method comprising:
receiving, from a network, a plurality of downlink control informations (DCIs) comprising scheduling information for sidelink (SL) resources;
transmitting, to a second device, a plurality of physical sidelink shared (channels (PSSCHs) based on the SL resources;
obtaining hybrid automatic repeat request (HARQ) feedback information for the plurality of PSSCHs based on one or more receptions through a physical sidelink feedback channel (PSFCH); and
transmitting, to the network, the HARQ feedback information for the plurality of PSSCHs,
wherein each of the plurality of DCIs informs i) a corresponding physical uplink control channel (PUCCH) resource, and ii) a slot of the corresponding PUCCH resource relative to a PSFCH slot, and
wherein the HARQ feedback information for the plurality of PSSCHs is transmitted on a PUCCH resource informed by a last DCI among the plurality of DCIs, based on the plurality of DCIs informing a same slot for the corresponding PUCCH resource.
