CONTROL OF SIMULTANEOUS USE OF WIRELESS LINKS IN INTEGRATED ACCESS BACKHAULED NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18249340 titled 'CONTROL OF SIMULTANEOUS USE OF WIRELESS LINKS IN INTEGRATED ACCESS BACKHAULED NETWORKS
Simplified Explanation
The abstract describes a patent application for a technology called Integrated Access and Backhaul (IAB) network. In this network, an IAB-node is configured to perform BAP-sublayer processing, which involves transmitting BAP packets over multiple RLC channels. The BAP-sublayer processing can duplicate a received BAP packet and append the same sequence number to all the duplicates. This allows another IAB-node to recognize and terminate the duplication. Alternatively, the BAP-sublayer processing can network encode a received BAP packet and assign successive sequence numbers to the resulting packets. Another IAB-node can then recognize and terminate the network coding. The terminator of the BAP-layer processing discards duplicates or decodes packets with successive sequence numbers to terminate the duplication process. This approach increases the robustness of the wireless network, distributes processing loads across multiple IAB-nodes, and reduces bandwidth waste.

Original Abstract Submitted
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.
