1. A transmission apparatus, comprising:
transmission circuitry, which, in operation, transmits a signal of a random access channel; and
control circuitry, which, in operation, configures a preamble sequence from among a plurality of preamble sequence candidates, the preamble sequence used for the signal,
wherein
the preamble sequence with a cyclic prefix transmitted on a first random access channel (RACH) occasion and the preamble sequence with a cyclic prefix transmitted on a second RACH occasion are discontinuous in a time domain such that the cyclic prefix transmitted on the second RACH occasion is spaced from the preamble sequence transmitted on the first RACH occasion in the time domain, and
a total number of Zadoff-Chu (ZC) sequences included in the preamble sequence differs from a total number of ZC sequences included in a preamble sequence of another cell.
