| 摘要 |
The present invention discloses a method for reducing multi-cell interference. The method is comprised of dividing a cell into a plurality of segments, partitioning a frequency spectrum into a plurality of sub-channels, assigning one or more sub-carriers to each of the plurality of sub-channels, assigning a predetermined sub-channel as a primary channel to a predetermined segment, determining which of the plurality of the segments a desired communicating wireless mobile station enters, calculating a first spatial signature of desired signals from the desired communicating wireless mobile station, calculating a second spatial signature of interference signals from a plurality of non-communicating wireless mobile stations in one or more neighboring cells, and generating a null-steering beamforming weighting vector from the first and second spatial signatures. |
