Abstract:
1. A method for sequencing Zadoff-Chu sequences of a random access channel, characterized by, comprising: setting α as a logical index of each Zadoff-Chu sequence, and u as a physical index of said each Zadoff-Chu sequence, wherein 1≦u≦N−1, 0≦α≦N−2, and N is the length of said each Zadoff-Chu sequence; and establishing a mapping relationship between the logical index and the physical index: u=N/2 is taken as a symmetry axis, α is mapped to u in a manner of longitudinal symmetry, and on the upper side of the symmetry axis, u monotonously decreases or increases, while on the lower side of the symmetry axis, u monotonously increases or decreases.
