Solution Overview

Problem

The existing wireless communications networks face challenges in reducing overheads for reporting scheduling bandwidth and modulation and coding scheme thresholds due to the high frequency bands above 6 GHz, which exacerbate phase noise issues, particularly in next-generation communications networks like NR.

Innovation Solution

The terminal device reports scheduling bandwidth thresholds as natural number powers of 2, using elements to indicate these thresholds, thereby reducing the data amount and resource overheads by compressing the value range and quantity of thresholds reported.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the terminal device reports detailed scheduling bandwidth thresholds in the existing manner, then the reporting accuracy is maintained, but the overhead for reporting thresholds increases

Engineering Contradiction:
Improvereporting accuracyVSAvoidreporting overhead
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts only the essential information needed for reporting by identifying and reporting only the bandwidth threshold values that actually change, rather than reporting all possible threshold parameters. This selective extraction reduces reporting overhead while maintaining necessary accuracy for phase noise compensation in high-frequency communications.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of reporting all bandwidth thresholds and letting the network device filter them, the patent inverts the approach by having the terminal device report only the changed threshold values directly, reversing the traditional filtering logic and significantly reducing reporting data volume.

Inventive Principle:
Principle #13The other way round (Inversion)

2Loss of information

If the terminal device reports all scheduling bandwidth thresholds, then complete information is provided to the network device, but the data amount and resource consumption increase

Engineering Contradiction:
Improveinformation completenessVSAvoidresource consumption
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent extracts only the essential changed bandwidth threshold values from the complete set of thresholds, reporting only what is necessary for the network device to maintain accurate scheduling decisions, thereby reducing data transmission energy consumption while preserving information completeness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the reporting parameter from reporting all threshold values to reporting only the changed threshold values, dynamically adjusting what is reported based on actual changes in bandwidth allocation, which reduces resource consumption while maintaining information completeness.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the terminal device reports scheduling bandwidth thresholds frequently, then the network device has up-to-date information, but the reporting overhead and latency increase

Engineering Contradiction:
Improveinformation freshnessVSAvoidreporting latency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements periodic reporting only when bandwidth threshold changes occur, rather than reporting at fixed intervals regardless of changes. This event-driven periodic action maintains information freshness by reporting when necessary while avoiding unnecessary reporting delays and overhead.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The terminal device autonomously determines when reporting is necessary by monitoring its own bandwidth threshold changes, eliminating the need for network-triggered reporting queries. This self-service approach reduces reporting latency by immediately reporting changes without waiting for network requests.

Inventive Principle:
Principle #25Self-service

AI summary

This application discloses a data reporting method, a data receiving method, and a related apparatus. In this application, a terminal device reports, to a network device, one group of information used to indicate scheduling bandwidth thresholds and/or scheduling MCS thresholds. Compared with directly reporting thresholds, in this application, fewer bits can be occupied, thereby reducing overheads.
