Abstract

The present invention provides an information transmission method, a base station, a mobile terminal, and a computer-readable storage medium, and solves the problem of increasing the congestion probability of random access when more mobile terminals access RACH resources configured at a fixed frequency point question. The information transmission method of the present invention includes: sending the configuration information of the target frequency point used by the mobile terminal in the random access process to the mobile terminal, the configuration information including the time slot information corresponding to the target frequency point and / or the time slot information of the target frequency point Identification information. The configuration information in the embodiment of the present invention carries the time slot information corresponding to the target frequency point and / or the identification information of the target frequency point, so that the mobile terminal can complete uplink access on different frequency points when performing random access, Effectively reduce the probability of access failure or random access congestion.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to an information transmission method, a base station, a mobile terminal and a computer-readable storage medium. Background technique [0002] In the existing random access, the mobile terminal performs access on the RACH resources configured at a fixed frequency point. This implementation method has low flexibility, and when the number of UEs is large, the congestion probability of the random access will be increased. [0003] At the same time, if 5G NR (new air interface) is deployed on the C carrier (about 3.5GHz), the budget difference between the uplink and downlink of 3.5GHz is large (the downlink transmission loss is about 10dB less than the uplink transmission loss), resulting in the uplink coverage being significantly smaller than the downlink coverage range, the uplink coverage will be limited, and the access success rate of mobile terminals at t...
