摘要

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.

主权项

1. A mobile communication method, comprising:
a step of assigning predetermined sequences, in which an amplitude is constant in a temporal domain and a frequency domain and self-correlation is 0, to each cell; a step of generating a plurality of preambles by performing a cyclic shift with respect to the predetermined sequences by a predetermined period in each cell; and a step of acquiring a reception timing distribution of preambles in the predetermined period in each cell, wherein the reception timing distribution of the preambles includes the number of preambles in each of divided areas obtained by dividing a reception window into a predetermined number of areas.
