Abstract: Apparatuses and methods for flexible resource allocation for sidelink transmissions. A method of a user equipment (UE) in a wireless communication system includes receiving higher layer parameters including a bitmap; determining a first number S>1; and determining a sidelink resource pool based on the bitmap and the first number S, wherein bits in the bitmap indicate whether a group of S consecutive slots are included in the sidelink resource pool. The method further includes determining a second number L; determining L consecutive orthogonal frequency division multiplexing (OFDM) symbols within the S consecutive slots, wherein the L consecutive OFDM symbols are used for a physical sidelink shared channel (PSSCH) or a physical sidelink control channel (PSCCH); and receiving the PSSCH or the PSCCH.
