Random access signaling transmitting method and transmitting device

The invention provides a random access signaling transmitting method and a transmitting device. The transmitting method is characterized in that at least one of the following parameters can be determined according to a random access signaling transmitting scene and/or an attribute of a second node: a random access signaling parameter, and a parameter of a random access channel used for transmitting the random access signaling; and the second node can be used to transmit the random access signaling by the random access channel according to the determined parameter. The costs of the system access can be effectively reduced.
