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 a radio resource control, RRC, message including first configuration information and second configuration information, the first configuration information including information for indicating that a measurement gap is a pre-configured measurement gap and information on sharing of the pre-configured measurement gap, the second configuration information including information for indicating that the pre-configured measurement gap is activated or deactivated, wherein
• the pre-configured measurement gap is activated or deactivated, based on switching of a downlink bandwidth part, BWP, according to the information for indicating that the pre-configured measurement gap is activated or deactivated included in the second configuration information in a case where the first configuration information includes the information for indicating that the measurement gap is the pre-configured measurement gap, and
• a sharing scheme based on the information on the sharing of the pre-configured measurement gap is applied to the activated pre-configured measurement gap in a case where the pre-configured measurement gap is activated.

A communication method of an apparatus, comprising:

• receiving a radio resource control, RRC, message including first configuration information and second configuration information, the first configuration information including information for indicating that a measurement gap is a pre-configured measurement gap and information on sharing of the pre-configured measurement gap, the second configuration information including information for indicating that the pre-configured measurement gap is activated or deactivated;
• activating or deactivating, based on switching of a downlink bandwidth part, BWP, the pre-configured measurement gap according to the information for indicating that the pre-configured measurement gap is activated or deactivated included in the second configuration information in a case where the first configuration information includes the information for indicating that the measurement gap is the pre-configured measurement gap;
• and
• applying a sharing scheme based on the information on the sharing of the pre-configured measurement gap to the activated pre-configured measurement gap in a case where the pre-configured measurement gap is activated.
