Method and apparatus for configuring resources and transmitting/receiving data in wireless cellular communication system

A method for a user equipment (UE) in a wireless communication system, the method comprising:

• receiving, from a base station, bandwidth part (BWP) configuration information by higher layer signaling;
• receiving, from the base station, downlink control information (DCI) including information indicating an active BWP based on the BWP configuration information;
• identifying grant free resource configuration information associated with the active BWP;
• and
• transmitting, to the base station, data based on the grant free resource configuration information.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a processor operably connected to the transceiver, the processor configured to:
• transmit, to a user equipment (UE), bandwidth part (BWP) configuration information by higher layer signaling;
• transmit, to the UE, downlink control information (DCI) including information indicating an active BWP based on the BWP configuration information;
• identify grant free resource configuration information associated with the active BWP;
• and
• receive, from the UE, data based on the grant free resource configuration information.
