Method for controlling random access power of UE, UE and computer storage medium

A user equipment (UE), comprising a processor, a network interface, and a memory for storing a computer program which is runnable on the processor, wherein the processor is configured to:

• control the network interface to receive system broadcast information sent from a network side;
• obtain a scaling factor corresponding to a speed of the UE from the system broadcast information, wherein the scaling factor corresponding to the speed of the UE comprises at least one of the following:
• a power adjustment parameter for the UE to perform random access, an adjustment parameter for a power ramp step, or an adjustment parameter for a random access fallback, wherein the power adjustment parameter for the UE to perform random access comprises a factor or offset for a target receive power of an initially transmitted preamble for the UE to perform the random access, the adjustment parameter for the power ramp step comprises a factor or offset for the power ramp step when the UE performs the random access, and the adjustment parameter for the random access fallback comprises a factor or offset for the random access fallback;
• and
• correct a power in a random access procedure of the UE and a time for transmitting a preamble in the random access procedure based on the scaling factor corresponding to the speed of the UE;
• wherein the processor is further configured to obtain a corrected random access fallback based on multiplication of a random access fallback that is randomly generated and the factor for the random access fallback;
• or obtain the corrected random access fallback based on addition of the random access fallback that is randomly generated and the offset for the random access fallback.

• wherein the processor is further configured to:
• obtain a corrected reference value for the random access fallback based on multiplication of a random access fallback indicated by the network side and the factor for the random access fallback;
• or obtain the corrected reference value for the random access fallback based on addition of the random access fallback indicated by the network side and the offset for the random access fallback;
• and
• generate a corrected value for the random access fallback according to the corrected reference value for the random access fallback, wherein the corrected value for the random access fallback is greater than zero and smaller than the corrected reference value for the random access fallback.
