Ericsson and Deutsche Telekom published a joint whitepaper that describes a concept for rate adaptation in 5G networks based on Low Latency Low Loss Scalable throughput (L4S), a mechanism being standardized in IETF (Internet Engineering Task Force).
The overall objective is to enable a large scale of time-critical high data rate applications over 5G mobile networks and the companies believe a common feedback loop mechanism is required for fast rate adaptation.
