Abstract:
A mobile communication method according to the present invention includes a step of assigning one or a plurality of Zadoff-Chu sequences to each of cells #A to #G, a step of generating a plurality of RACH preambles by performing a cyclic shift with respect to the assigned Zadoff-Chu sequences by a predetermined period Ncs in each of the cells #A to #G, and a step of acquiring the reception timing distribution of the RACH preambles in the predetermined period Ncs in each of the cells #A to #G.
