Method and apparatus for switching bandwidth part in new radio

A method of switching bandwidth part (BWP) by a base station (BS), the method comprising:

• receiving information on physical layer capability that includes information on a BWP switching delay type, from a UE;
• transmitting downlink control information (DCI) including a BWP indication field that indicates one BWP different from an active BWP among BWPs included in a BWP set configured for the UE, and scheduling control information for a data channel;
• and
• transceiving the data channel according to the scheduling control information if a BWP indicated by a value of the BWP indication field is activated in consideration of a transition time determined by the information on the BWP switching delay type.

A user equipment (UE) for switching bandwidth part (BWP), the UE comprising

• a transmitter configured to transmit information on physical layer capability comprising information on a BWP switching delay type;
• a receiver configured to receive downlink control information (DCI) comprising a BWP indication field that indicates one BWP different from an active BWP among BWPs included in a BWP set configured for the UE, and scheduling control information for a data channel;
• and
• a controller configured to activate the BWP indicated by a value of the BWP indication field in consideration of a transition time determined by the information on the BWP switching delay type, and controls the transmitter and the receiver to transmit and receive the data channel according to the scheduling control information.
