Method and apparatus for resource allocation and bandwidth part inactivity timer handling for vehicle-to-everything communication

A terminal in a wireless communication system, comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to:
• receive, from a base station via the transceiver, configuration information on a sidelink (SL) communication including information on one or more SL resource pools and information on a bandwidth part (BWP) for each of the one or more SL resource pools,
• receive, from the base station via the transceiver, downlink control information (DCI) indicating resources for the SL communication from the one or more SL resource pools,
• identify the resources and the BWP for the SL communication based on the configuration information and the DCI, and
• perform the SL communication based on the resources on the BWP.
