Method and system for extracting channel impulse response for mobile terminals from a neighboring cell |
摘要 |
Finding a channel impulse response estimation window in a current cell for at least one mobile terminal in a neighboring cell is disclosed. This can serve to mitigate interference caused by mobile terminals in neighboring cells in and among communications ongoing in a current cell. In one example, a method for A method for determining such a channel impulse response estimation window includes presetting, in the neighboring cell, at least two channel impulse response peak locations of respective mobile terminals in first and second predetermined periods with a predetermined peak location change pattern, and then upon receiving communication from a mobile terminal of the neighboring cell, analyzing channel impulse responses to identify the peak location change pattern with regard to first and second peak locations. The method further includes identifying a variation range for a channel impulse response of a primary path of the mobile terminal, and determining a channel impulse response estimation window for the mobile terminal based on the identified variation range and a preferred estimation window size. |
