FIELD: information technology.
SUBSTANCE: techniques for dynamically varying coverage in a multi-carrier communication system are described. A sector may operate on multiple carriers. The sector may vary coverage on a given carrier k based on its load, so that less interference may be caused to other sectors when the sector load is light. In one configuration, the sector may communicate on a first carrier at a first transmission power level and on a second carrier at a second transmission power level equal to or lower than the first transmission power level. The sector may vary the second transmission power level based on its load to vary the coverage of the second carrier. The sector may reduce the second transmission power level to zero or a low level if the sector load is light. The sector may also vary the second transmission power level based on a function of sector load or a switching pattern.
EFFECT: reduced interference in multi-carrier communication systems.
