Solution Overview

Problem

In 5G wireless communication systems, especially in above 6 GHz (A6G) distributed massive MIMO systems, effective beam selection is challenging due to the presence of multiple beams from different antenna panels, leading to decreased system throughput and potential data transmission interruptions when user equipment (UE) posture changes or transmission signals are blocked.

Innovation Solution

A method and apparatus for dynamically selecting a suitable serving beam for each UE by acquiring network and UE-related information, determining candidate beams based on this information, and allocating resources to ensure continuous data transmission and improved system performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple beams are transmitted from different antenna panels to cover a service area, then coverage is improved, but beam selection complexity increases and system throughput decreases

Engineering Contradiction:
Improvecoverage areaVSAvoidbeam selection complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The base station divides the service area into multiple beam coverage regions, each associated with specific antenna panels. The beam management entity segments the beam selection process by determining candidate beams based on UE location information and selecting serving beams from these candidates, thereby managing complexity while maintaining comprehensive coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A beam management entity is introduced as an intermediary component at the base station. This entity receives UE location information, determines candidate beams based on the UE's position, and selects appropriate serving beams. This intermediary layer simplifies the overall beam selection complexity by centralizing the decision-making process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Area of stationary object

If multiple beams are transmitted from different antenna panels, then coverage is improved, but system throughput decreases due to selection difficulty

Engineering Contradiction:
Improvecoverage areaVSAvoidsystem throughput
Core Design Contradiction:
Area of stationary objectVSProductivity

Solution Approach 1:

The beam management entity performs preliminary actions by determining candidate beams in advance based on UE location information before actual data transmission. This preliminary beam selection reduces the time and complexity of beam switching during data transmission, thereby improving system throughput while maintaining comprehensive coverage.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The beam selection process is made dynamic by continuously updating candidate beams based on real-time UE location information. The beam management entity adapts the serving beam selection as the UE moves or changes posture, ensuring optimal throughput while maintaining coverage across the service area.

Inventive Principle:
Principle #15Dynamics

3Reliability

If beam selection is performed dynamically based on UE posture changes, then transmission reliability is improved, but processing complexity increases

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidbeam management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses feedback mechanisms where the beam management entity receives UE location information and beam quality measurements, then adjusts candidate beam determination and serving beam selection accordingly. This feedback loop ensures reliable data transmission during UE posture changes while managing complexity through automated decision-making based on measured parameters.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The beam management entity performs self-service by autonomously determining candidate beams and selecting serving beams based on UE location information and beam quality measurements. This self-service capability reduces the need for complex external control while maintaining high transmission reliability during UE movement and posture changes.

Inventive Principle:
Principle #25Self-service
