Random access method, apparatus, terminal, electronic device and readable storage medium

Abstract

The application provides a random access method and device, a terminal, electronic equipment and a readable storage medium. The method comprises the following steps: determining a time adjustment step according to a physical random access channel (PRACH) format configured by a serving cell where a current terminal is located and a wireless signal propagation speed; determining an initial time advance according to positioning information obtained from a positioning system; determining a time advance (TA) according to the time adjustment step, a number of trial rounds and the initial time advance; and initiating at least one round of random access attempts to a base station according to the TA until the current terminal successfully accesses the base station. The TA is determined according to the time adjustment step, the number of trial rounds and the initial time advance, so that the TA is more accurate, and in the case that the cell coverage requirement exceeds the maximum coverage radius supported by a protocol (or a communication system), the random access request can still be accurately sent to the serving base station according to the TA, and the terminal can successfully access the base station, thereby improving the success rate of the terminal random access.
