Interference mitigation in a wireless communication system

A method of coordinating operation of a plurality of base stations, comprising:

• reducing, during at least one first time interval, transmission power associated with at least one first channel provided by at least one first base station associated with at least one corresponding first coverage area adjacent at least one second coverage area associated with at least one second base station concurrently with maintaining at least one transmission power associated with said at least one second base station;
• and
• increasing, during at least one second time interval subsequent to said at least one first time interval, the transmission power associated with said at least one first channel provided by said at least one first base station concurrently with reducing at least one transmission power associated with at least one first channel provided by said at least one second base station, wherein said at least one first time interval and said at least one second time interval are predetermined according to a repeating pattern, wherein a beginning and an end of said at least one first and second time intervals are determined independently by said at least one first base station and said at least one second base station according to free running clocks in said at least one first base station and said at least one second base station, and wherein the free running clocks are not synchronized.
