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

A method for coordinating in device coexistence (IDC) interference by an eNodeB (eNB), the method comprising:

• receiving, from a user equipment (UE), first assistance information regarding a first coordination of IDC interference through a first frequency, the first assistance information comprising information of the first frequency of a Long Term Evolution (LTE) frequency band;
• receiving, from the UE, second assistance information regarding a second coordination of IDC interference, the second coordination being based on a Time Division Multiplexing (TDM) technique when a change of the first assistance information occurs;
• and
• transmitting, to the UE, a response responsive to the second assistance information,
• wherein the response comprises information indicating whether the second assistance information is accepted or rejected, and
• wherein the second assistance information comprises information about a victim system of the IDC interference.

A user equipment (UE) to support in device coexistence (IDC) interference coordination, the UE comprising:

• a processor configured to trigger a first coordination of IDC interference on reception through a first frequency;
• and
• a wireless transceiver to transmit, to an eNodeB (eNB), first assistance information for the first coordination of IDC interference through the first frequency, the first assistance information comprising information of the first frequency of a Long Term Evolution (LTE) frequency band,
• wherein the processor is configured to retrigger a second coordination of IDC interference after the first coordination is triggered, the second coordination being based on a Time Division Multiplexing (TDM) technique when a change of the first assistance information occurs,
• wherein the wireless transceiver transmits, to the eNB, second assistance information for the second coordination of IDC interference, the second coordination being based on a Time Division Multiplexing (TDM) technique when a change of the first assistance information occurs, and receives, from the eNB, a response responsive to the second assistance information, and
• wherein the response comprises information indicating whether the second assistance information is accepted or rejected, and
• wherein the second assistance information comprises information about a victim system of the IDC interference.
