Abstract:
Embodiments of the present invention provide a preamble sequence transmission method, apparatus, and system. The method includes: acquiring system information or a physical broadcast channel (PBCH) that is broadcast by a base station, wherein the system information or the PBCH comprises a preset physical random access channel (PRACH) that comprises m preset radio frames and a number of repetition times of a preamble sequence n, which is used for random access, m being a positive integer and wherein 1≤n≤10 m; and sending the preamble sequence to the base station, the preamble sequence being sent at n preset resource locations of the preset PRACH, where the preamble sequence is the format of 1 ms, or the format of 2 ms, or the format of 3 ms.
