Abstract
The disclosure provides a method and device for processing a random access preamble. The method includes: determining a Guard Time (GT) required by communication between a User Equipment (UE) and a base station according to a cell coverage radius, wherein the cell coverage radius is larger than 100 kilometers; and determining the random access preamble transmitted by the UE to the base station according to the GT, wherein the random access preamble is transmitted on an ordinary sub-frame in a radio frame during the communication between the UE and the base station. By the method and the device, the problem that the cell coverage radius of a single station cannot exceed 100 kilometers in a related technology is solved, and effects of enlarging the cell coverage radius of the single station and meeting a requirement on an ultra-large cell coverage radius in a special scenario are further achieved.
