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: Proposed is a method for performing wireless communication by a first device. The method may comprise a step of: transmitting a physical sidelink shared channel (PSSCH) through a resource selected in a first time area to a second device; receiving a physical sidelink feedback channel (PSFCH) related to the PSSCH from the second device; and on the basis that the interval between the first time area and a second time area is larger than a preconfigured threshold value, selecting a resource in the second time area to retransmit the PSSCH to the second device. For example, the first time area may precede the PSFCH. For example, the second time area may follow the PSFCH.

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.
