Method and apparatus for measurement for inter-cell interference coordination in radio communication system
First Claim
1. A method for supporting measurement of a User Equipment (UE) by a first base station in a wireless communication system, the method comprising:
- acquiring, by the first base station, information of a downlink subframe configuration of a second base station;
determining, by the first base station, measurement objects of a downlink resource of the first base station based on the downlink subframe configuration of the second base station;
transmitting, by the first base station, information of the measurement objects to the UE; and
receiving, by the first base station, a measurement result for the measurement objects from the UE,wherein the information of the measurement objects restricts a measurement region on which the UE performs a measurement to at least one specific Orthogonal Frequency Division Multiplexing (OFDM) symbol of at least one downlink subframe of the first base station, andwherein the downlink subframe configuration of the second base station includes information indicating at least one subframe of the second base station configured as an Almost Blank Subframe (ABS).
