Random access method and device and configuration indication method and device

Abstract

The present disclosure relates to a random access method and device, and a configuration indication method and device, the random access method comprising: initiating random access based on first random access configuration information in response to the fact that a terminal autonomously determines a timing advance, and initiating random access based on second random access configuration information in response to the fact that the terminal non-autonomously determines the timing advance; wherein the first random access configuration information is different from the second random access configuration information. According to the embodiment of the invention, under the condition that the terminal autonomously determines the timing advance, the capacity of random access in unit time is improved, the scheduling delay is reduced, and under the condition that the timing advance is not autonomously determined, the interval of random access resources is ensured to meet the error of the communication delay.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a random access method, a configuration indication method, a random access device, a configuration indication device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of communication technology, it is necessary to be able to communicate between base stations and terminals at any location on the ground. However, since the base stations in the current network are located on the ground, there are many restrictions on setting up base stations, and it is difficult to fully cover the ground through ground base stations. Therefore, Consider incorporating satellite coverage. [0003] In the terrestrial network, the base station may send a timing advance (Timing Advance, TA for short) to the terminal, so that the uplink signal frame sent by the terminal corresponds to the downlink signal frame sent by ...

AI Technical Summary

Problems solved by technology

[0004] However, when communicating with satellites in a non-terrestrial network (NTN), since the satellites are in the air and moving at high speed, when the base station communicates with the terminal through the satellite, there is a large delay, and the timing The advance is set according to the delay, so the timing advance is relatively large, which will cause some problems
