Patent ID: 8116794

Claim:
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 1 and the second peak location as T 2 for a first mobile terminal with T 2 >T 1 ; and setting the first and second peak locations for each subsequent mobile terminal alternately based on a relation defined by (n−1)*W+T 2 and (n−1)*W+T 1 and a relation defined by (n−1)*W+T 1 and (n−1)*W+T 2 , where W denotes the preferred estimation window size and n denotes the nth mobile terminal.
