Solution Overview

Problem

In Reconfigurable Intelligent Surface (RIS) and relay systems, the RIS or relay node cannot measure and report beam management signals from the network side, preventing the determination of optimal transmission beams for links between the RIS/relay node and the network device or terminal.

Innovation Solution

A measurement and reporting method where a first node device, capable of digital signal processing, measures and reports beam information by performing processes such as beam sweeping and adjustment matrix training, using configuration information provided by the network side to obtain optimal beam information for single-hop links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If RIS node or relay node cannot measure and report beam management signals, then device complexity is reduced, but optimal beam information of single hop links cannot be obtained

Engineering Contradiction:
ImproveRIS node complexityVSAvoidoptimal beam information
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent introduces a first node device (such as a control node or another relay node with measurement capability) as an intermediary to perform beam management signal measurement and reporting. This intermediary device measures the beam management signals sent by the network side device and reports the measurement results, enabling the RIS node or relay node to obtain optimal beam information without requiring them to have measurement and reporting capabilities themselves.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If first node device performs measurement and reporting, then optimal beam information is obtained, but beam training time increases

Engineering Contradiction:
Improvebeam information accuracyVSAvoidbeam training time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the first node device obtain configuration information in advance and perform measurement and reporting operations proactively. The network side device configures measurement resources and reporting parameters beforehand, allowing the first node device to conduct beam management signal measurements and submit reports without waiting for real-time triggers, thereby reducing overall beam training time while maintaining measurement precision.

Inventive Principle:
Principle #10Preliminary action
