Symmetric Slice Control xApps via O-RAN RC SM

Chieh-Chun Chen
Mikel Irazabal

An xApp that enables RAN slicing through the O-RAN standardized RAN Control (RC) service model, allowing real-time control of per-slice radio resource ratios in accordance with 3GPP-defined Radio Resource Management (RRM) policies.

Detailed Description

This xApp leverages the O-RAN standardized RC service model to control RRM policy ratios within the RAN. It enables operators to configure dedicated, minimum, and maximum radio resource ratios for each 3GPP-defined network slice, identified by the Single Network Slice Selection Assistance Information (S-NSSAI). Through real-time updates of slice policy ratios via the O-RAN E2 interface, the xApp provides dynamic and symmetric control of uplink and downlink radio resource allocation across slices, supporting efficient resource utilization and adaptive traffic management.

Key Features

  • O-RAN E2 interface compliant
  • Real-time control of per-slice RRM policy ratios

Use Cases

  • Slice-level QoS management
  • Optimization of radio resource utilization across slices
