Abstract: Proposed is a method for performing wireless communication by a first device. The method may comprise the steps of: receiving, from a base station, information related to a configured grant (CG) for scheduling a sidelink resource; and on the basis of the information related to the CG, performing sidelink transmission to a second device on the basis of a sidelink resource allocated by the CG. For example, the information related to the CG may include information relating to an offset related to the CG and information relating to a period related to the CG. For example, the sidelink resource allocated by the CG may be positioned in a slot spaced apart by the offset related to the CG from the closest logical sidelink slot after a time point at which a system frame number (SFN) corresponds to 0. For example, the sidelink resource allocated by the CG may repeat at the period related the CG. For example, the period related to the CG and the offset related to the CG may be in units of logical sidelink slots. For example, the logical sidelink slot may be a resource within a sidelink resource pool.

Abstract: A method by which a first apparatus performs wireless communication is proposed. The method may comprise the steps of receiving a first time division duplex uplink-downlink (TDD UL-DL) configuration related to LTE, obtaining a second TDD UL-DL configuration related to NR sidelink communication, on the basis of the first TDD UL-DL configuration, and performing the NR sidelink communication with a second apparatus on a carrier related to the LTE, on the basis of the second TDD UL-DL configuration. For example, the first TDD UL-DL configuration may comprise a UL subframe, a DL subframe, and a special subframe. For example, the special subframe may comprise a downlink pilot time slot (Dwpts) symbol, an uplink pilot time slot (Uppts) symbol, and a gap symbol. For example, on the basis of the Uppts symbol and gap symbol related to the first TDD UL-DL configuration overlapping a first symbol related to the second TDD UL-DL configuration, the NR sidelink communication may be allowed, for the first apparatus, in the first symbol.

Abstract: According to an embodiment of the present disclosure, provided is a method for performing sidelink communication by a first device. The method may comprise the steps of: performing first SL reception in a first time interval in which an on-duration timer relating to an SL DRX operation operates; performing second SL reception in a third time interval included in a second time interval in which the on-duration timer does not operate; and performing SL transmission related to at least one of the first SL reception and the second SL reception, wherein the first SL reception performed in the first time interval within a CBR window includes PSCCH reception and PSSCH reception, the second SL reception performed in the third time interval within the CBR window includes the PSCCH reception and does not include the PSSCH reception, and on the basis that the second SL reception performed in the third time interval includes the PSCCH reception and does not include the PSSCH reception, a first CBR value related to the second time interval is determined as a ratio of sub-channels, which have an SL RSSI value equal to or greater than a configured first threshold value and include a PSCCH resource, from among all sub-channels to be attempted for PSCCH detection.
