Abstract

The invention discloses an information transmission method and terminal. The information transmission method comprises the steps: carrying out random access through a target HARQ process under the condition that the configuration authorization and random access process schedules the same target HARQ process. According to the embodiment of the invention, when the random access process conflicts with other HARQ processes configured and authorized to schedule, the random access process is carried out through the target HARQ process, so that the normal operation of the random access process when the HARQ processes conflict can be ensured, and the problem of failure of the random access process caused by HARQ process conflict is avoided.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an information transmission method and a terminal. Background technique [0002] In the mobile communication system, the terminal can achieve different purposes through the random access process, such as: the initial access of the terminal (the terminal is connected to the network in the initial idle state), radio resource control (Radio Resource Control, RRC) reconstruction, handover, downlink Data arrives but uplink out of sync, uplink data arrives but uplink out of sync, terminal changes from inactive to active, uplink synchronization acquisition of secondary cell (Scell) is supported, etc. At present, the random access process is divided into a contention random access process and a non-contention random access process. Wherein, the non-contention random access process only requires two-step access of message one (message1, msg1) and message two (message2, m...
