Abstract
A method of efficiently transmitting CoMP feedback information from an user equipment, which performs CoMP operation, in a wireless communication system to reduce inter-cell interference is disclosed. The user equipment requests a neighboring cell, which affects the user equipment through interference, to restrict use of a specific beam pattern group in a serving cell direction. In this case, whether the user equipment will request such restriction is determined based on a channel status value of the user equipment. If the user equipment determines to request such restriction, the user equipment transmits a request message to a serving base station, the request message requesting to restrict use of the specific beam pattern group. In this case, the user equipment performs scheduling and requests a specific neighboring cell to restrict use of the specific beam pattern group at a specific resource region.
