Abstract: An aspect of the present disclosure is a method for user equipment in a wireless communication system, wherein a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) are received on an aggregation slot including a plurality of slots, and a sidelink signal is transmitted on a resource selected on the basis of at least one among a reference signal received power (RSRP), a received signal strength indication (RSSI), and a reference signal received quality (RSRQ), which are measured from the aggregation slot. The RSRP is measured from each of slots, on which a plurality of PSCCHs are received, among the plurality of slots on the basis of the plurality of PSCCHs being received on the aggregation slot.

Abstract: A method and an apparatus for sidelink of a wireless communication system are proposed. The present disclosure proposes an example in which a TX UE or a RX UE sets a length of an ACK/NACK signal adaptively. The TX UE may set the length of the ACK/NACK signal based on various elements such as priority, length, and service coverage of sidelink data, and the RX UE may set the length of the ACK/NACK signal based on various elements obtained from a process for receiving the sidelink data.

Abstract: A method and apparatus for a sidelink of a wireless communication system are proposed. A transmission UE can contiguously or non-contiguously allocate radio resources through sidelink communication. A specific resource allocation method is selected in consideration of latency of sidelink data/packets or other factors. For example, a specific resource allocation method can be determined based on whether a plurality of contiguous subchannels is allocated to radio resources before a first time, which is determined based on latency of data/packets.

Abstract: Provided are a method by which a first device performs wireless communication, and an apparatus supporting same. The method may comprise the steps of: allocating at least one resource block (RB) from among a set of a plurality of RBs for a physical sidelink feedback channel (PSFCH) in a PSFCH slot, with respect to a physical sidelink shared channel (PSSCH) resource; performing PSSCH reception from a second device on the basis of the PSSCH resource related to the PSFCH slot; and transmitting hybrid automatic repeat request acknowledgment (HARQ-ACK) information to the second device in response to the PSSCH reception, on the basis of the at least one RB allocated with respect to the PSSCH resource.
