AI Technical Summary

Technical Problem

Existing wireless communication systems lack efficient mechanisms for determining the applicability of artificial intelligence and machine learning (AI/ML) functionalities during conditional handover (CHO) processes, leading to suboptimal handover decisions.

Method used

A wireless transmit/receive unit (WTRU) is configured to receive CHO configurations that include AI/ML functionalities based on signal level ranges, allowing it to determine applicable AI/ML functionalities for candidate cells and select a target cell for handover, and send an indication if applicable functionalities are not available.

Benefits of technology

Enhances the efficiency and effectiveness of handover processes by optimizing the use of AI/ML functionalities, ensuring seamless and intelligent handover decisions based on real-time signal conditions.

Abstract

A wireless transmit / receive unit (WTRU), which include one or more processors, may be configured to receive a configuration to activate one or more artificial intelligence or machine learning (AI / ML) functionalities and to receive conditional handover (CHO) configurations to one or more candidate cells, and a plurality of signal level thresholds associated with the serving cell. The WTRU may be configured to compare the serving cell signal level with each of the plurality of serving cell signal level thresholds and determine applicabilities of each of the one or more AI / ML functionalities for the CHO configurations based on the comparisons between the serving cell signal level and each of the one or more serving cell signal level thresholds.
