Solution Overview

Problem

Current wireless communication systems, particularly in 5G and LTE networks, face challenges in efficiently measuring and reporting beam metrics for multiple transmit beams, which affects the suitability and performance of simultaneous reception by user equipment (UE), leading to potential throughput gains that are not accurately reflected in existing reporting mechanisms.

Innovation Solution

The implementation of a method where user equipment (UE) receives a configuration for a group-based beam report, measures beam metrics, and provides an indication of the number of receive beams used to receive transmissions, allowing network entities to determine if multiple transmit beams are received by a single or multiple receive beams, thereby enhancing the accuracy of beam reporting and performance assessment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If group-based beam reporting is implemented to report metrics for multiple transmit beams, then beam measurement efficiency is improved, but the ability to accurately determine if multiple transmit beams are received by a single or multiple receive beams deteriorates

Engineering Contradiction:
Improvebeam measurement efficiencyVSAvoidbeam reception accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent segments the beam reporting information by introducing a separate field indicating the number of receive beams used. This divides the reporting structure into two parts: group-based beam metrics and receive beam configuration information, allowing both efficiency and precision requirements to be met simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary indicator field that mediates between the group-based beam reporting mechanism and the network's need to determine receive beam configuration. This intermediate element carries the specific information about whether multiple transmit beams are received by a single or multiple receive beams without disrupting the efficient group-based reporting structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If detailed beam metric reporting is implemented for all transmit beams, then beam selection accuracy is improved, but signaling overhead and processing complexity increase

Engineering Contradiction:
Improvebeam selection accuracyVSAvoidreporting complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts only the essential information needed for beam selection accuracy (the number of receive beams used) from the complete beam reporting data. This selective extraction provides the network with sufficient information to determine beam reception configuration without requiring detailed reporting of all individual beam metrics, thereby reducing signaling overhead and processing complexity.

Inventive Principle:
Principle #2Taking out (Extraction)
