The advantages of the regenerative architecture are three-fold. First, it limits the propagation time on the NR interface, which makes up the lowest protocol stack layers and this means a lower propagation delay and a higher throughput in effect. Second, the downlink does not have to carry the IQ of the signal and can instead be logic (ie bits) encapsulated in a more efficient waveform for the purpose of feeder-link transmissions. Third, the regenerative architecture offers new potential features, e.g. Device2Device loop-back calls through satellite without ground-segment (billing and setup with the core-network, but otherwise reduced latency i.e. higher throughput), store-and-forward functionality for satellites that are out of ground-station coverage, or even satellite network including satellites dedicated to core functionality that would provide low-latency core-network services to other satellites interconnected via ISL.
