The present invention provides cyclic power changing patterns for transmissions in different sectors of a cellular system. The cyclic power changing patterns define unique patterns in which transmission power levels change over a period of time slots or within a group of sub-carriers. Each sector has a unique pattern, so that interference information monitored by the user elements, which are supported by base stations, are indicative of the interference contributions from adjacent sectors. Based on these interference contributions and the cyclic power changing patterns associated with these sectors, the base stations can schedule transmissions to the user elements during time slots or in sub-carriers to minimize the impact of interference from the adjacent sectors and to efficiently support dynamic needs of the individual user data packets according to QoS requirements.
