Abstract: Suggested is a novel condition for a media access control (MAC) entity in user equipment (UE) reselecting a sidelink resource in a wireless communication system. The MAC entity of the UE can reselect a sidelink resource when a configured sidelink grant does not satisfy a latency requirement according to ProSe per-packet priority (PPPP). More particularly, configuration is performed by an upper layer so that the MAC entity transmits on the basis of sensing using a resource pool; the MAC entity selects generation of a configured sidelink grant corresponding to transmission of a plurality of MAC protocol data units (PDU); and when data is available in a sidelink traffic channel (STCH) and the configured sidelink grant does not satisfy the latency requirement according to the PPPP, a sidelink resource is reselected.

Abstract: A video decoding method performed by a decoding device includes: deriving control points (CPs) for a current block; acquiring motion vectors for the CPs; deriving a sample-unit motion vector in the current block based on the acquired motion vectors; deriving a prediction sample for the current block based on the sample-unit motion vector; and generating a restoration sample based on the prediction sample, wherein coordinates of a bottom-right sample position of the current block are (0, 0), and coordinates of CPO among the CPs are (0, 0). Inter prediction is effectively performed through sample-unit motion vectors even when an image in a current block is planarly moved and variously changed, and since motion vectors for CPs are derived based on already-decoded neighboring blocks, an amount of information for the motion vectors for the CPs and for a residual signal for the current block is reduced, improving overall coding efficiency.
