The invention relates to the field of communication technology, in particular to an uplink transmission method and a device in random access, so as to improve the success rate of a competition based random access process. Including a random access uplink transmission method provided by the embodiment of the invention, the user equipment UE to send the random access network side equipment in receiving a response message, a plurality of pilot signals from the pilot signal indicating the parameter information of the network side equipment issued in the selection of a pilot UE signal; in the random access response message indicating the time and frequency resources, to the pilot signal by the network side device for transmitting uplink user data and selection. The embodiment of the invention, when multiple UE in random access the same resource to the base station sends a random access preamble after the same probability can increase the number of UE use of the pilot signal in different transmission of upstream user data, which can improve the random access process the success rate based on competition.
