Claim Text:
1. A method of user equipment controlling In-Device Coexistence (IDC) interference in a wireless communication system, the method comprising: receiving measurement configuration information, comprising an IDC triggering threshold used as a condition that an IDC event indicating that an on-going IDC interference state has started is triggered, from a base station; performing measurement considering IDC influence in a serving cell and measurement not considering IDC influence in a neighbor cell based on the measurement configuration information; triggering the IDC event if a difference between a result of the measurement considering IDC influence and a result of the measurement not considering IDC influence is greater than the IDC triggering threshold; and transmitting measurement report information, comprising IDC indication indicating whether the IDC event has been triggered or not and the result of the measurement considering IDC influence or the result of the measurement not considering IDC influence, to the base station, wherein performing the measurement considering IDC influence in the serving cell comprises: performing measurement based on measurement samples in which integration interference, including all IDC interference, inter-cell interference, and thermal noise in the serving cell, is taken into consideration, and performing the measurement not considering IDC influence in the neighbor cell comprises performing measurement based on measurement samples in which inter-cell interference and thermal noise in the neighbor cell are taken into consideration.
