Abstract
A method and a device for contention-based random access are provided. The method includes: sending, by a terminal side device, an Msg1 corresponding to a two-step contention-based random access to a network side device; receiving, by the terminal side device, an Msg2 returned by the network side device, wherein if the terminal side device determines a failure of the two-step contention-based random access occurs according to a receiving condition of the Msg2 message, the terminal side device performs a handling procedure for the failure of the two-step contention-based random access. The Msg2 message is determined by the network side device according to a receiving condition that the network side device receives the Msg1 message.
