Apparatus and method for controlling in-device coexistence interference in wireless communication system

A method for controlling an interference by a Base Station (BS) in a wireless communication system, the method comprising:

• receiving, from a User Equipment (UE), UE capability information that indicates whether the UE has a capability to send an In-Device Coexistence (IDC) indication;
• transmitting, to the UE, IDC enabling information that indicates whether the UE is allowed to send an IDC indication;
• and
• receiving the IDC indication from the UE, the IDC indication including updated unusable frequency information,
• wherein the updated unusable frequency information has been updated according to an IDC interference control operation.

A User Equipment (UE) for controlling an interference in a wireless communication system, the UE comprising:

• a transmitter to transmit, to a base station (BS), UE capability information that indicates whether the UE has a capability to send an In-Device Coexistence (IDC) indication;
• and
• a receiver to receive, from the BS, IDC enabling information that indicates whether the UE is allowed to send an IDC indication,
• wherein the transmitter transmits the IDC indication to the BS, the IDC indication including updated unusable frequency information,
• wherein the updated unusable frequency information has been updated according to an IDC interference control operation.

A Base Station (BS) for controlling an interference in a wireless communication system, the BS comprising:

• a receiver to receive, from a User Equipment (UE), UE capability information that indicates whether the UE has a capability to send an In-Device Coexistence (IDC) indication;
• a processor to generate IDC enabling information that indicates whether the UE is allowed to send an IDC indication;
• and
• a transmitter to transmit the IDC enabling information to the UE,
• wherein the receiver receives the IDC indication from the UE, and
• wherein the IDC indication includes updated unusable frequency information which has been updated according to an IDC interference control operation.
