Problems solved by technology

UE falls back from two-step random access to four-step random access, which will lead to waste of transmission resources
When the number of UEs performing fallback is large, a large amount of transmission resources will be wasted, which will affect system access efficiency and transmission performance

Abstract

The invention provides a transmission method and device, a terminal, a base station, a communication system and a storage medium. The method comprises the steps of obtaining a first index; acquiring first information; and if it is determined that the first index meets a first preset rule according to the first information, determining that the content to be transmitted comprises a first message. According to the embodiment of the invention, if the first index is determined to meet the first preset rule according to the first information, the to-be-transmitted content is determined to comprisethe first message, and the transmission of the first message can be controlled, so that transmission resource collision can be reduced, transmission resource waste is reduced, and system access efficiency and transmission performance are improved.

Description

Technical field [0001] This application relates to the field of communications, in particular to transmission methods, devices, terminals, base stations, communication systems and storage media. Background technique [0002] In related technologies, for example, a long-term evolution (Long Term Evolution, LTE) communication system, or a new radio access technology (New Radio Access Technology, New RAT or NR) communication system, when a terminal or user equipment (User Equipment, UE) ) When downlink data needs to be received, a cell search process is required to obtain downlink synchronization with the cell. Similarly, when the UE needs to perform uplink transmission, it needs to obtain uplink synchronization with the cell. After the UE completes the uplink and downlink synchronization, it enters a radio resource control (Radio Resource Control, RRC) connection state, and establishes a wireless connection with a base station (Base Station, BS), so that uplink and downlink data c...
