In an Integrated Access and Backhaul, IAB, network, an IAB-node is configured as an initiator for performing BAP-sublayer processing to the aim of transmitting BAP packets over multiple RLC channels. BAP-sublayer processing may duplicate a received BAP packet. The same sequence number is appended to all the duplicates to allow another IAB-node terminating the duplication to recognize them. In a variant, BAP-sublayer processing may network encode one received BAP packet. Successive sequence numbers are assigned to the resulting BAP packets to allow another IAB-node terminating the network coding to recognize them. A terminator of the BAP-layer processing thus terminates the duplication by discarding all duplicates except one or network decodes received packets with successive sequence numbers. Duplication process may be nested within another duplication or within a network encoding. This approach advantageously increases robustness of a wireless network, distributes the processing loads over multiple IAB-nodes and reduces bandwidth waste.
