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.

Abstract: The disclosure provides air-ground co-frequency system interference suppression method. The method includes: determining base station set of ground radio communication system corresponding to first base station of ATG system, where each second base station in base station set and first base station interfere with each other; determining, for at least one second base station, location of RIS device corresponding to second base station, and determining incident angle of incident beam of interference signal incident to RIS device; and determining, according to interference signal and incident angle of incident beam of interference signal, weight information of reflected beam of interference cancellation signal so that RIS device reflects incident beam of interference signal according to weight information, to form reflected beam of interference cancellation signal to eliminate interference signal. The disclosure further provides air-ground co-frequency system interference suppression apparatus, electronic device, and readable medium.
