The invention provides an information transmission method, a base station, a mobile terminal and a computer-readable storage medium, which solve the problem that when more mobile terminals access RACHresources configured at a fixed frequency point, the congestion probability of random access is improved. The information transmission method of the invention comprises the following steps: the configuration information of the target frequency point used by the mobile terminal in the random access process is sent to the mobile terminal; the configuration information comprises time slot information corresponding to the target frequency point and / or identification information of the target frequency point. The configuration information of the embodiment of the 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 the uplink access at different frequency points when performing the random access, thereby effectively reducing the access failure probability or the random access congestion probability.
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...
