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

A Mobile Station (MS), for controlling interference in the MS, comprising:

• a receiver to receive, from a Base Station (BS), Radio Resource Control (RRC) connection reconfiguration including In-device coexistence (IDC) Discontinuous Reception (DRX) configuration reconfiguring DRX relating to an unusable frequency band based on IDC indication information;
• and
• an IDC resolution processor to reconfigure DRX based on the IDC DRX configuration to autonomously deny Industrial Scientific Medical (ISM) transmission in the unusable frequency band,
• wherein the IDC DRX configuration include information configuration a DRX retransmission timer and information configuring a DRX short cycle to a predetermined cycle for avoiding the IDC interference,
• wherein the RRC connection reconfiguration further includes information for configuring the IDC DRX configuration which is not related to IDC interference, and
• wherein the IDC DRX configuration which is not related to IDC interference is based on a time division multiplexing (TDM) operation.

A method for controlling interference in a Base station (BS), comprising:

• receiving, from a Mobile Station (MS), IDC indication information including an unusable frequency band that is frequency band in which performing communication is interfered by IDC interference;
• determining IDC Discontinuous Reception (DRX) configuration reconfiguring DRX relating to the unusable frequency band based on the IDC indication information, and selecting IDC resolution operation autonomously denying Industrial Scientific Medical (ISM) transmission in the unusable frequency band;
• and
• transmitting, to the UE, Radio Resource Control (RRC) connection reconfiguration including the IDC DRX configuration and the IDC resolution operation,
• wherein the IDC DRX configuration includes information configuring a DRX retransmission timer and information configuring a DRX short cycle to a predetermined cycle for avoiding the IDC interference,
• wherein the RRC connection reconfiguration further includes information for configuring the IDC DRX configuration which is not related to IDC interference, and
• wherein the IDC DRX configuration which is not related to IDC interference is based on a time division multiplexing (TDM) operation.
