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: A method for performing wireless communication by a first device, and an apparatus supporting same. The method includes: determining a first PSSCH resource, a second PSSCH resource, and a third PSSCH resource; and transmitting, to a second device, Sidelink Control Information (SCI) including information related to frequency domains of the second PSSCH resource and the third PSSCH resource on a first PSCCH resource related to the first PSSCH resource. Here, the information related to the frequency domains is obtained on the basis of the number of subchannels included in a resource pool, an index of a starting subchannel of the second PSSCH resource, an index of a starting subchannel of the third PSSCH resource, the number of subchannels included in the second PSSCH resource, and the number of subchannels included in the third PSSCH resource, and the information related to the frequency domains may be a zero or positive integer.

Abstract: A method of performing wireless communication by a first device is proposed. The method includes receiving downlink control information (DCI) related to first sidelink from a base station, and transmitting, to the base station, a confirmation message for reception of the DCI related to the first sidelink through a first medium access control (MAC) control element (CE). For example, the first MAC CE may include at least one index information related to at least one semi-persistent scheduling (SPS) configuration activated or released by the DCI.

Abstract: A method by which a first device performs wireless communication is presented. The method can comprise the steps of: determining a first selection window for selecting a resource related to sidelink transmission; determining N number of preset second selection windows in the first selection window; selecting a resource on the basis of the number of idle resources in the N number of second selection windows; and transmitting, on the resource, a PSCCH and a PSCCH related to the PSCCH to a second device. For example, N can be a positive integer.
