: The paper Random Access for LEO Satellite Communication Systems via Opportunistic Transmission (available on arXiv) describes how a Satellite Base Station (SBS) computes transmission probabilities and transmits RAR messages to users to handle collisions in low-earth orbit systems.
: Technical summaries such as R1-230xxxx from 3GPP detail the latest enhancements to the Random Access Channel (RACH) procedure and PRACH coverage. tdl.rar
: It highlights how transmission delays are managed during heavy traffic, a core issue in the TDL/RAR framework. Additional Resources on RAR and TDL : The paper Random Access for LEO Satellite

: For performance assessments using TDL (Tapped Delay Line) channel models, you can refer to the Performance Assessment of NB-IoT Protocol Over Satellite Channels report from UPCommons, which uses TDL models to simulate and analyze Block Error Rates (BLER).
The following paper discusses the random access procedure, preamble generation, and delay optimization, which are critical components of the RAR process in modern networks:
