The present invention provides a method and an apparatus for generating secondary synchronization signals, wherein the method comprises steps of: determining a value of iteration times M according to a total number N of cell ID groups or a cell ID group index NID(1), wherein M is a natural number; calculating to obtain M cyclic shift accumulation parameters qk (k=0, 1 . . . M−1) through M times of iterations; calculating a common cyclic shift factor m′ through q0; calculating a first cyclic shift value m0 and a second cyclic shift value m1 according to m′; and generating the secondary synchronization signals according to m0 and m1. The present invention solves the problem that the method for generating the secondary synchronization signals in related arts cannot support a greater number of cell ID groups.
