Abstract: This document discloses a solution of interference coordination in wireless communication systems where a base station may request a specified load report from another base station. A first base station may store load information of terminal devices associated with the identifier of strongest interference source for each terminal device. The first base station may receive a load report request from a second base station. The first base station may respond to the second base station with a load report including load information of only terminal devices whose strongest interference source is the second base station. The second base station may receive the load report further and provide communication resources on the basis of the received load report.

Abstract: A method for use in a user equipment, including transferring data to the base station of a first cell (A1); sending an uplink scheduling request to the base station of a second cell (A3) in dependence on the condition that the user equipment has sufficient transmission power for performing inter-site carrier aggregation (A2); receiving an uplink resource allocation message from the base station of the second cell (A5) if the load of the second cell satisfies predetermined conditions (A4); transferring data to the base stations of the first and second cells via carrier aggregation (A6).
