METHOD FOR MITIGATING INTER-CELL INTERFERENCE IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
First Claim
1. A method for canceling inter-cell interference in a wireless communication system, the method comprising;
- receiving time resource interference information about a first subframe type and a second subframe type from a neighbor cell;
receiving first frequency resource interference information about the first subframe type and second frequency resource interference information about the second subframe type from the neighbor cell; and
conducting downlink communication and uplink communication using the first frequency resource interference information, the second frequency resource interference information, and the time resource interference information.

Abstract
The present application provides a method for allowing a cell to remove inter-cell interference in a wireless communication system. Specifically, said method comprises the steps of: receiving, from neighboring cells, time resource interference information on a first subframe type and a second subframe type; receiving, from said neighboring cells, first frequency resource interference information corresponding to said first subframe type and second frequency resource interference information corresponding to said second subframe type; and performing downlink communication and uplink communication by using said first frequency resource interference information, said second frequency resource interference information, and said time resource interference information.
