Abstract:
A method for performing a handoff in a radio communication system, said method comprising the steps of:determining per time slot a sum of output power of simultaneously transmitted signals from a first base station; determining if at least one alternative time slot exists on said first base station which has a sum of output power below a second threshold; performing, if at least one alternative time slot exists, an intra-cell handoff from a first time slot having a sum of output power which exceeds the first threshold to one of said at least one alternative time slot; and determining, when an intra-cell handoff is to be performed, which user to move to said one of said at least one alternative time slot based on one or more of a number of time slots to which a user is assigned, a power requirement of said user, signal strength, signal quality and type of service.
