Summary - Q.5032 (06/2024) - Network coding protocol for network repeaters

Recommendation ITU-T Q.5032 considers networks with repeaters. A repeater is usually a device designed to receive a signal from a remote transmitter and then retransmit this signal to a remote receiver that is unable to receive a signal from the original transmitter without retransmission due to certain conditions, for example, due to too large a distance, transmission medium, low power of the source signal, or other reasons. Implementation of network coding at a repeater with a two-way relay channel allows us to reduce the network load and, consequently, data transmission delays in such networks.
This Recommendation includes:
–description of a network architecture where the protocol could be implemented;
–coding and decoding procedures;
–packet types and formats;
–signalling procedures and diagrams.
