AI Technical Summary

Technical Problem

The existing O-RAN architecture lacks a defined interface for efficient data collection from radio units (O-RUs) to non-real-time and near-real-time RAN Intelligent Controllers (RICs), limiting the ability to collect essential data for AI/ML-based operations, particularly in 6G communication systems.

Method used

A method and apparatus are introduced for a 6G open fronthaul interface that enables a distributed unit (O-DU) to transmit data collection setting information, including extended antenna-carrier identifiers (eAxC IDs) and physical resource block (PRB) settings, to radio units (O-RUs), generating control messages for data collection, and supporting efficient data collection through section type and extension type formats.

Benefits of technology

Facilitates efficient data collection from O-RUs to RICs, enhancing AI/ML-based operations by managing data rates and collecting necessary information for network optimization and training, thereby improving the performance of 6G communication systems.

Abstract

The present disclosure relates to a method carried out by an O-DU for controlling connections to user apparatuses, the method comprising the steps of: transmitting, to an O-RU, a management message including eAxC ID allocation information corresponding to a layer or a port and PRB configuration information for I / Q data collection; and generating a control message including one or more of a section-type format and a section extension-type format for data collection and transmitting same to the O-RU, wherein the one or more of the section-type format and the section extension-type format include information related to an eAxC ID associated with data collection and information related to a PRB from which data is to be collected.
