Abstract

This disclosure relates generally to wireless communications and, more particularly, to systems and methods for determining an adaptive random access response window length in non-terrestrial networks. In one embodiment, a method performed by a communication device includes: receiving system information from a communication node, wherein the communication node communicates using a satellite in orbit or a high altitude platform station (HAPS); and determining an adaptive random access response window length based on the system information and whether the communication device has access to situation information that: characterizes a location of the communication device, an ephemeris of the satellite or a trajectory of the HAPS, and a payload type of the satellite or the HAPS.
