Wireless communication method and system for minimizing interference by determining mobile station zone locations and potential conflicts between cell zones

摘要

A wireless communication method and system for minimizing severe interference to one or more wireless transmit/receive unit (WTRUs). A plurality of non-overlapping zones (e.g., an inner zone and an outer zone) is defined for each cell of a wireless multi-cell communication system, such as a time division duplex (TDD) system. Information regarding potential conflicts between the non-overlapping cell zones is obtained. Each potential conflict indicates that there is a high likelihood of one of the WTRUs using a specific time slot for transmitting in a zone of one cell causing severe interference to a second one of the WTRUs using the specific time slot for receiving in a zone of another (i.e., a different) cell. Time slot usage (e.g., uplink, downlink or none) is then determined on a zone-by-zone basis using the obtained information to minimize interference caused by a conflicting uplink assignment or a conflicting downlink assignment.
