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.

Abstract: A user equipment (UE) may attempt to access an edge data network. The UE generates a first credential based on a second credential that was generated for a procedure between the UE and a network. The UE then generates an identifier corresponding to the first credential and generates a message authentication code based on the first credential and a count, wherein the count is associated with an identifier of an edge network client running on the UE. The UE then transmits an application registration request, message to a server associated with an edge data network, the application registration request message including the count, the message authentication code, the identifier corresponding to the first credential, and a public land mobile network identifier (PLMN ID) of the network. The UE then receives an authentication accept message or an authentication reject message from the server associated with the edge data network.

In response to decoding the RRC reconfiguration message, the L1 configuration corresponding to the second cell is stored. A cell change message received from the first cell is decoded. The cell change message indicates that a cell change from the first cell to the second cell is to be performed. The stored L1 configuration corresponding to the second cell is applied for data transmission and reception associated with the second cell. A cell change to the second cell is initiated.
