Patent ID: 7010071

Claim:
A method for synchronizing a base station with a mobile station, the method comprising the steps of: forming a synchronization sequence y(i) of length n, to be emitted by the base station, in accordance with the following relationship from a first constituent sequence x 1 of length n 1 and a second constituent sequence x 2 of length n 2 : y(i)=x 2 (i mod n 2 )*x 1 (i div n 2 ) for i=0 . . . (n 1 *n 2 )−1; and forming at least one constituent sequence x 1 or x 2 in accordance with the following relationship from a third constituent sequence x 3 of length n 3 and a fourth constituent sequence x 4 of length n 4 : x 1 ( i )= x 4 ( i mod s+s *( i div sn 3 ))* x 3 (( i div s ) mod n 3 ), i= 0 . . . ( n 3 *n 4 )−1; or x 2 ( i )= x 4 ( i mod s+s *( i div sn 3 ))* x 3 (( i div s ) mod n 3 ), i= 0 . . . ( n 3 *n 4 )−1.
