Abstract:
1. A method of minimizing interference in a wireless multi-cell communication system that serves a plurality of wireless transmit/receive units (WTRUs), the method comprising: (a) defining a plurality of non-overlapping zones in a conflicting zone lookup table for each cell in the system; (b) obtaining information from the conflicting zone lookup table regarding potential conflicts between the non-overlapping cell zones, wherein the conflicting zone lookup table specifically identifies each of the zones of the cells, and each potential conflict indicates that there is a high likelihood of one of the WTRUs using a specific time slot for transmitting in one of the specifically identified zones of one cell causing severe interference to a second one of the WTRUs using the specific time slot for receiving in one of the specifically identified zones of another cell; and (c) determining time slot usage on a zone-by-zone basis using the information obtained from the conflicting zone lookup table to minimize interference caused by a conflicting uplink assignment or a conflicting downlink assignment.
