Abstract: A method and communication system (e.g., TDD system) that uses adaptive antennas at the base stations to monitor metrics associated with the quality of one or more CPCH timeslots, so as to determine whether to reuse some or all of the CPCH timeslots to transmit the DPCH. If it is determined to reuse some or all of the CPCH timeslots, an additional determination is made as to what limit to apply on the DPCH transmission powers. Adaptive antennas may be used at the base stations to allow the system to reuse some or all of the CPCH timeslots to transmit DPCH, thus improving the overall capacity of the system while maintaining the CPCH coverage and quality at a desired level throughout the system.

Abstract: The present invention establishes a system on how to best use adaptive antennas at a base stations and optionally at wireless transmit receive units (WTRUs) to mitigate the interference due to conflicting slot assignments between two neighboring cells. This system will allow for a greater flexibility in slot-to-cell assignments, especially when conflicting slot assignments are for two cells or mobiles in the same vicinity, more specifically, one cell uses a slot assignment for an uplink while the other cell uses the same slot assignment for downlink.
