Abstract: A random access method, a base station, an UE and a device with a storage function are disclosed. The random access method includes: the base station receiving a first message transmitted by the UE, the first message including a preamble message and a signal message; decoding the preamble message and the signal message respectively; if the decoding of preamble message is succeeded, but the decoding of signal message fails, the base station transmits a second message to the UE, and storing the signal message of decoding failure, the second message configured to request the UE to retransmit the signal message; receiving the third message transmitted by the UE, the third message including the signal message; using a chase combine mechanism to decode the third message according to the stored signal message in the first message. The present disclosure save time and improve the efficiency of random access.

Abstract: A random access method, a base station, and a user equipment (UE) are disclosed. The random access method includes: transmitting a first message for random access for the UE, the first message including a preamble message and a signal message; receiving a second message and a fourth message for random access for the UE at a time and determining random access for the UE is successful upon receiving the second message and the fourth message; and upon reception of a second message configured to request the UE to transmit the signal message, transmitting a third message comprising the signal message, receiving the fourth message in response to the third message, and determining random access for the UE is successful upon receiving the fourth message.
