Abstract:
Systems and methods for implementing various metrics for in integrated IAB networks are disclosed. A child IAB node may determine metrics regarding one or more of its data flows and report these metrics to an upstream IAB node (that is a parent node and/or an IAB donor). The upstream node may determine a data flow prioritization configuration using these metrics that it either uses itself or sends back to the child IAB node or another IAB node of the IAB network for use there. Metrics discussed include a number of hops metric, an aggregate throughput per BH RLC channel ID (or per routing ID) metric, a fairness index per BH RLC channel ID (or per routing ID) metric, a packet drop metric, and a per-hop latency for aggregated traffic per BH RLC channel ID (or per routing ID) per IAB node metric.
