Apparatus, base station, and communication method

A base station comprising:

• a memory storing a program;
• and
• one or more processors configured to execute the program to:
• transmit, to an apparatus, a radio resource control, RRC, message including a measurement gap configuration, the measurement gap configuration including information for indicating that a measurement gap is a pre-configured measurement gap;
• control a state of the pre-configured measurement gap as any of activation and deactivation;
• control switching of a downlink bandwidth part, BWP;
• and
• determine the state of the pre-configured measurement gap as deactivation in a case where a measurement based on a synchronization signal and physical broadcast channel block, SSB, on the downlink BWP after the switching is performed and the downlink BWP after the switching is an initial downlink BWP.

A communication method of an apparatus, comprising:

• receiving, from a base station, a radio resource control, RRC, message including a measurement gap configuration, the measurement gap configuration including information for indicating that a measurement gap is a pre-configured measurement gap;
• determining a state of the pre-configured measurement gap as any of activation and deactivation;
• controlling switching of a downlink bandwidth part, BWP;
• and
• determining the state of the pre-configured measurement gap as deactivation in a case where a measurement based on a synchronization signal and physical broadcast channel block, SSB, on the downlink BWP after the switching is performed and the downlink BWP after the switching is an initial downlink BWP.
