Abstract:
1. A method for determining a channel impulse response estimation window in a current cell for at least one mobile terminal in a neighboring cell, comprising: 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; 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; 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, the presetting comprising: setting the first peak location as T setting the first and second peak locations for each subsequent mobile terminal alternately based on a relation defined by (n−1)*W+T
