Abstract

A random access method and a device thereof are provided. The method includes that a base station receives a random access preamble and sends a Random Access Response (RAR) according to the random access preamble, where the RAR indicates at least two time-frequency units, and the at least two time-frequency units are time-frequency units having different time domains on an unlicensed channel. Further, the base station receives a first random access message 3 (MSG3) sent on a first time-frequency unit by a first terminal and sends a first random access message 4 (MSG4) to the first terminal, where the first time-frequency unit is any one of the at least two time-frequency units, where the first MSG3 includes a terminal identifier of the first terminal, where the first MSG4 carries a terminal identifier of the first terminal and a first Cell-Radio Network Temporary Identifier allocated to the first terminal.
