RAN Slicing rApp

Ali Yaghoubian

A cloud-native and O-RAN compliant rApp designed to enforce the load balancing policy via O-RAN standardized A1 interface, enabling slice-specific control of maximum downlink Physical Radio Resource (PRB) allocation in the RAN.

release

Detailed Description

This rApp generates and sends load-balancing policies to the Non-RT RIC via the R1 interface. The Non-RT RIC forwards these policies to the Near-RT RIC over the A1 interface, where a corresponding xApp enforces them at the gNB through the E2 interface. This end-to-end workflow enables the creation and control of network slices with defined maximum downlink PRB allocation in the RAN.

Key Features

  • O-RAN A1 and R1 interface compliant
  • Near real-time slicing policy enforcement
  • Centralized management of network slicing policies
  • Cloud-native rApp architecture for scalability and portability

Use Cases

  • Dynamic slice-aware load balancing across cells
  • Centralized RAN slicing policy control

RAN KPI and Configuration Dataset

RAN KPI and Configuration Dataset

Ali Yaghoubian

This dataset contains 1-second–granularity time-series measurements collected from a 5G laboratory testbed operating on band n78. It combines detailed RAN configuration parameters (e.g., center frequency, and TDD patterns) with key MAC-layer KPIs such as ACK/NACK statistics, bitrate, MCS, etc. The dataset is intended for research and development tasks including configuration-to-KPI modeling, RAN tuning and optimization, and control algorithm evaluation.
