: Technical summaries such as R1-230xxxx from 3GPP detail the latest enhancements to the Random Access Channel (RACH) procedure and PRACH coverage.
: 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. tdl.rar
: 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). : Technical summaries such as R1-230xxxx from 3GPP
