Abstract: Radio network devices (30, 31) operative in a wireless communication network are autonomously distributed among available narrowband carriers for receiving and transmitting messages from and to the network according to each device's (30, 31) required enhanced coverage level, and the enhanced coverage levels supported by each narrowband carrier.

Based on this feedback (22), the transmitting radio node (12) adapts a level of redundancy that the transmitting radio node (12) uses for data block transmission to the receiving radio node (14).
