A method performed by a user equipment (UE) is provided. The method includes receiving resource configuration information for a sidelink; identifying a set of slots based on a subcarrier spacing configured for the UE; based on a bitmap included in the resource configuration information, identifying at least one slot for a sidelink resource, among the identified set of slots except specific slots, wherein the specific slots include a slot configured for a sidelink synchronization signal, a slot in which at least one symbol included in a subset of the slot is not configured as an uplink (UL) and a reserved slot; and transmitting a physical sidelink shared channel (PSSCH) on the identified at least one slot.
