AI Technical Summary

Technical Problem

In mobile communications, it is difficult to identify the relationship between user equipment and reconfigurable smart surface devices, especially when not communicating with user equipment. Reconfigurable smart surface devices may shut down on their own, making interference management and beam management optimization difficult.

Method used

By transmitting multi-directional beam scans through network nodes, combined with Reference Signal Received Power (RSRP) measurements and uplink reference signal transmission, the association between user equipment and reconstructed smart surface devices can be identified.

Benefits of technology

Effectively identify the association between user equipment and reconfigurable smart surface devices, reduce interference, optimize beam management, and improve communication quality.

Abstract

Techniques for identifying an association between a reconfigurable intelligent surface (RIS) and a user equipment (UE) in mobile communications are described. A device (e.g., a network node) transmits a first set of beams in multiple directions to scan a service area of the network node. The device also transmits a second set of beams in a direction of a reconfigurable intelligent surface that directs the second set of beams to a service area of the reconfigurable intelligent surface. In response, the device receives a report from a user equipment. Based on the report, the device classifies the user equipment as being directly connected to the network node or associated with the reconfigurable intelligent surface.
