    Abstract: A method for optimizing service-level-policy-based network performance management in a 5G wireless network slice includes: analyzing, by a slice analytics module, a target slice throughput of the slice in comparison to an observed slice throughput of the slice to compute a slice-throughput error function; and updating, by the slice analytics module, based on at least the slice-throughput error function, at least one of the following: i) radio resource management policy maximum ratio for the slice and a corresponding shared pool of resource blocks (RBs) for the slice; ii) radio resource management policy minimum ratio for the slice and a corresponding prioritized pool of RBs for the slice; and iii) radio resource management policy dedicated ratio for the slice and a corresponding dedicated pool of RBs for the slice.

    Abstract: A method for optimizing Control Unit (CU)-Distributed Unit (DU) flow control to detect congestion over midhaul and take corrective action to reduce packet dropping in the midhaul includes: computing, by DU, desired data rate (DDR) for each data radio bearer (DRB); and sending, by the DU, the DDR every time when desired buffer size (DBS) is sent from DU to CU user plane (CU-UP), along with Downlink Data Delivery Status (DDDS). DU computes DDR for a DRB as follows: DDR=TBS(MCS″, prb″, rank)*(number of slots/subframe in 1 sec)*(beta)*(beta_drb), with TBS being the Transport block size computation, and MCS″=min {(current MCS+MCS_step), MCSmax}.

    Abstract: A method for optimizing coexistence of low latency, low loss and scalable throughput (L4S) traffic and non-L4S traffic in a 5G wireless system is provided, which method includes one of: a) performing one of i) a flow control between a centralized unit (CU) and a distributed unit (DU), or ii) radio resource management at the DU, to reduce latency experienced by the L4S traffic; or b) performing one of iii) a flow control between the CU and the DU to facilitate greater frequency of transmission of non-L4S traffic from CU-user plane (CU-UP) to the DU, or iv) radio resource management at the DU, to reduce a scheduling priority metric of a logical channel for the L4S traffic relative to a scheduling priority metric of a logical channel for the non-L4S traffic. To reduce latency of the L4S traffic, the L4S traffic scheduling priority is increased relative to the non-L4S traffic.

    Abstract: A method for load balancing in an Open Radio Access Network (O-RAN) system having an overloaded serving cell of a first base station includes: determining, by at least the first base station, radio-resource-usage efficiency of each one of a subset of user equipments (UEs) in the overloaded serving cell; determining, by at least the first base station, from the subset of UEs a list of candidate UEs for handover from the overloaded serving cell to a non-overloaded neighboring cell, based on one of i) per-UE average physical resource block (PRB) usage over a specified time period, or ii) per-UE average of measurements involving modulation-and-coding-scheme over a specified time period; and handing over, by the first base station, at least a selected number of UEs from the list of candidate UEs to the non-overloaded neighboring cell to implement load balancing.
