What is HARQ Impact on MTC via Relay Nodes about?

This document summarizes a research paper about using relay nodes to extend coverage for machine type communication devices in 3GPP LTE networks. It describes how relay-assisted uplink transmission can help MTC devices located in coverage holes by using an intermediate relay node. However, the unknown and variable channel access delay when using technologies like WiFi to connect to the relay node disrupts the HARQ timeline. The paper proposes a signaling mechanism to adjust the HARQ timeline to account for
