Solution Overview

Problem

Current 5G wireless communication systems face high signaling overhead and delay in beam management, especially when serving multiple terminal devices, due to the need for repetitive signaling operations between base stations and user equipment, which is exacerbated by the use of millimeter-wave frequencies.

Innovation Solution

The proposed solution involves grouping terminal devices to share a common beam for communication, reducing unnecessary signaling overhead and delay by using a group common beam for multiple devices, thereby minimizing beam operations and signaling transmissions while maintaining reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual beam management is performed for each terminal device, then communication reliability is maintained, but signaling overhead and delay increase significantly

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidsignaling delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent groups multiple terminal devices into a common beam group, allowing the base station to perform beam management operations once for the entire group rather than individually for each device. This merging approach reduces signaling overhead and delay while maintaining communication reliability through group-based beam indication mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal beam management mechanism that serves multiple terminal devices simultaneously through a common beam. The group common beam configuration enables a single beam management procedure to fulfill the communication needs of multiple devices, improving efficiency without sacrificing individual device performance.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If individual beam management is performed for each terminal device, then communication reliability is maintained, but signaling overhead increases

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidsignaling overhead
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent merges beam management operations for multiple terminal devices into a single group-based operation. By combining devices into a common beam group, the system reduces the number of separate beam indication signals required, thereby reducing signaling overhead while maintaining reliable communication through the unified beam management approach.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a universal beam indication mechanism that serves multiple terminal devices through a common beam configuration. This multi-functional approach allows a single beam management signal to control communications for multiple devices simultaneously, significantly reducing the total signaling overhead compared to individual device management.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Quantity of substance

If millimeter-wave frequencies are used, then available spectrum resources increase, but path loss and atmospheric absorption loss increase

Engineering Contradiction:

Core Design Contradiction:
Quantity of substanceVSLoss of energy

Solution Approach 1:

The patent groups multiple terminal devices under a common beam to concentrate and leverage the available spectrum resources efficiently. By merging device communications into group-based beam operations, the system maximizes the utilization of millimeter-wave spectrum resources while managing signal loss through coordinated beam management.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent employs beamforming parameter adjustments to compensate for millimeter-wave signal losses. By dynamically optimizing beam parameters such as direction, width, and power distribution for group common beams, the system mitigates path loss and atmospheric absorption effects while maintaining effective use of high-frequency spectrum resources.
