Method and apparatus for reporting information of frequency affected by in-device coexistence interference in wireless communication system

A method, performed by a base station (BS), of receiving In-Device Coexistence (IDC) information, the method comprising:

• receiving, from a user equipment (UE), UE capability information comprising IDC information reporting capability information;
• transmitting, to the UE, configuration information about IDC information reporting;
• and
• receiving, from the UE, UE Assistance information comprising information of a frequency affected by an IDC problem,
• wherein the information of the frequency affected by the IDC problem is indicated in an IDC Assistance field.

A user equipment (UE) for providing In-Device Coexistence (IDC) information, the UE comprising:

• a transceiver;
• and
• a processor combined with the transceiver and configured to:
• transmit, to a base station (BS), UE capability information comprising IDC information reporting capability information,
• receive, from the BS, configuration information about IDC information reporting,
• detect an occurrence of an IDC problem, and
• transmit, to the BS, UE Assistance information comprising information of a frequency affected by the IDC problem, based on the configuration information,
• wherein the information of the frequency affected by the IDC problem is indicated in an IDC Assistance field.
