Abstract
A system and method for reducing bottleneck queues in the Open Radio Access Network (O-RAN) architecture through classification of Packet Data Convergence Protocol (PDCP) and Radio Link Control (RLC) queues at the Centralized Unit-User Plane (CU-UP). The system analyzes and determines a category for the CU-UP PDCP queue for the Data Radio Bearer (DRB), x, at the CU-UP and analyzes and determines a category for the DU RLC queue for the DRB, x, at the CU-UP. If the Congestion Indicator indicates Congestion Experienced (CE) for this DRB in the RAN, the system at the CU-UP starts inserting CE in the IP packet header for packets going in the reverse direction towards the application source, which in turn will modify the rate of transfer based on the number and duration of CE received.
