Handover challenges in disaggregated open RAN for LEO Satellites: tradeoff between handover delay and onboard processing

Given the advancements in next-generation low Earth orbit (LEO) satellites, there is an expected shift from transparent architectures (acting as radio repeaters) to regenerative architectures (hosting a part or all of the gNodeB (gNB) onboard). Such regenerative architectures enable disaggregation a...
