    Abstract: A method for performing wireless communication by a first apparatus and an apparatus for supporting same are provided. The method may comprise the steps of: receiving a physical sidelink control channel (PSCCH) from a second apparatus; receiving a physical sidelink shared channel (PSSCH) related to the PSCCH from the second apparatus; determining a physical sidelink feedback channel (PSFCH) resource related to the PSSCH, on the basis of a slot and sub-channel related to the PSSCH; and obtaining a channel busy ratio (CBR) value related to PSFCH transmission on the PSFCH resource. The CBR value may be obtained on the basis of (i) a first slot before a first offset from a slot that received the PSSCH related to the PSFCH resource, and (ii) measurement in a time section between the first slot and a second slot before a second offset.

    Abstract: Provided in some implementations is a sidelink-related operation method of a first user equipment (UE) in a wireless communication system, including the steps in which: a first UE receives, from a second UE, a physical sidelink control channel (PSCCH) including modulation coding scheme (MCS) information; a channel status information reference signal (CSI-RS) and a physical sidelink shared channel (PSSCH) related to the PSCCH are received; CSI is derived on the basis of the CSI-RS; and the first UE transmits, to the second UE, a CSI report including the CSI, wherein the CSI is derived on the basis of the determination of an MCS table.

    Abstract: An embodiment provides an operation method of a user equipment (UE) in a wireless communication system, the method comprising the steps of: transmitting 1st stage SCI (a sidelink control channel) on a physical sidelink control channel (PSCCH); and transmitting 2nd stage SCI on a physical sidelink shared channel (PSSCH), wherein the number of symbols for transmission of the 2nd stage SCI is determined using the number of resource elements (REs) related to the 2nd stage SCI, and the number of the resource elements (REs) related to the 2nd stage SCI is obtained by subtracting only the number of REs related to the PSCCH from the number of REs related to the PSSCH.

    Abstract: According to an embodiment of the present disclosure, a method for performing SL communication by a first device is provided. The method comprises the steps of: determining a plurality of first bits on which interleaving is to be performed from among a plurality of bits of a first encoded code block and a plurality of second bits except for the plurality of first bits from among the plurality of bits of the first encoded code block; performing interleaving on the plurality of first bits; transmitting, to a second device, the plurality of first bits on which the interleaving has been performed, on a plurality of first REs related to the plurality of first bits; and transmitting, to the second device, the plurality of second bits on a plurality of second REs related to the plurality of second bits.
