Abstract: A method and apparatus for resource allocation for sidelink configured grant is provided. A first wireless device receives, from a network, a cell specific Uplink (UL)-Downlink (DL) Time Division Duplex (TDD) configuration and considers that a first slot of a specific sidelink grant occurs in a logical slot determined based on a periodicity. The periodicity is determined based on a number of slots related to sidelink transmission, and the number of slots is determined based on the cell specific UL-DL TDD configuration.

Abstract: A method by which a first device performs wireless communication is proposed. The method may comprise the steps of: determining at least one candidate slot for selecting a sidelink (SL) resource; performing sensing for at least one sensing slot related to the at least one candidate slot; selecting the resource in the at least one candidate slot on the basis of the sensing; and performing SL communication with a second device on the basis of the selected resource. For example, the at least one sensing slot may be at least one slot which, from the at least one candidate slot, is located before a resource reservation period set for a resource pool.

Abstract: A method and apparatus for periodic transmissions for a configured grant is provided. A first device operating in a wireless communication system transmits, to a second device, a media access control (MAC) protocol data unit (PDU) by using a first resource of a configured grant (CG) in a first period for which the first resource of the CG is associated with a HARQ process identifier (ID), and flushes a HARQ buffer associated with the HARQ process ID in a second period for which a second resource of the CG is associated with the HARQ process ID. Then, the first device ignores a retransmission resource associated with the HARQ process ID based on flushing the HARQ buffer.
