Abstract

A method for allocating radio channels in a radio communications system having timeslots includes the steps of allocating the radio channel for the downlink direction to a mobile station as a function of a channel allocation pattern which indicates the transmission power levels for the timeslots. The mobile station corrects the allocation of the radio channel as a function of an interference pattern which indicates the interference power levels in the timeslots. The allocation process results in the transmission power level being distributed as uniformly as possible between the timeslots which are provided for a connection from the radio station in the downlink direction, wherein the allocation process is a function of the occupancy of the timeslots in accordance with the channel allocation pattern. The ability of correcting the allocated timeslot under the control of the mobile station allows to avoid a disadvantageous soft handover, even with a frequency repetition interval equal to unity which is critical with respect to interference.
