1. A random access method for communication between a user equipment (UE) and a base station, executed by the base station, comprising:
the base station receiving a first message for a random access, wherein the first message includes a preamble message and a signal message;
the base station decoding the preamble message and the signal message;
the base station transmitting, upon successfully decoding the first message, a second message and a fourth message at a time for the random access to notify that the random access is successful;
when the preamble message is successfully decoded while decoding of the signal message is failed, the base station transmitting the second message configured to request a third message that comprises the signal message;
upon reception of the third message transmitted in response to the second message, the base station decoding the signal message from the third message; and
when both the preamble message and the signal message are successfully decoded, the base station transmitting the fourth message configured to indicate that the random access is successful;
the second message comprises at least one of a time adjustment information, a cell radio network temporary identity, or an uplink resource allocation; and
the fourth message comprises a contention resolution.
