Abstract
A satellite computer system is configured to detect access request signals from terrestrial user equipment (UE). The satellite includes an antenna configured to send and receive signals to the UE on a radio access network (RAN) via beams that define cells of the RAN. The satellite computer system can perform steps that can include one or more of: detecting a coarse time offset of one or more access signals embedded in a signal received within a PRACH slot; detecting information identifying a root of a Zadoff-Chu sequence underlying each of the one or more access signals; generating, based on the identified root, potential pairs of frequency and time offset values for the access signals; selecting, based on the detected coarse time offset, one of the potential pairs; and sending, to the UE based on the selected pair, an access response formatted according to the RAN.
