Solution Overview

Problem

Current communication systems face inefficiencies when using directional beams, particularly in terms of resource utilization during beam sweeping processes, especially in scenarios with multiple base stations and high numbers of antenna elements, leading to increased power consumption and resource wastage.

Innovation Solution

A communication apparatus and method that dynamically adjust the settings of beam sweeping by forming groups of directional beams and optimizing resource allocation based on the status of the area covered, allowing for more efficient use of resources by changing the number of beams, frequency, and timing of sweeps depending on the number of terminal devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beam sweeping is performed with a large number of directional beams to improve coverage and reception quality, then the reception quality and coverage are improved, but the resource consumption and power usage increase significantly

Engineering Contradiction:
Improvereception qualityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent divides the set of directional beams into multiple beam groups, where each beam group contains a subset of beams. Instead of sweeping all beams individually, the system performs sweeping on a beam group basis, segmenting the overall beam sweeping process into smaller, more manageable units that consume less power while maintaining coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs beam sweeping partially by selecting and sweeping only certain beam groups based on system conditions, terminal locations, and coverage requirements. This partial action approach avoids the excessive power consumption of sweeping all possible beams while still achieving adequate coverage and reception quality.

Inventive Principle:
Principle #16Partial or excessive action

2Area of stationary object

If the number of directional beams is increased to improve area coverage, then the coverage area is expanded, but the resource usage and system complexity increase

Engineering Contradiction:
Improvecoverage areaVSAvoidresource usage
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The patent segments the coverage area by associating different beam groups with different geographical areas or terminal locations. Each beam group is responsible for covering a specific area, allowing the system to expand coverage by activating only the necessary beam groups rather than deploying all beams, thus optimizing resource usage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by configuring different beam groups with different characteristics suitable for their specific coverage areas. Each beam group is optimized for its local area requirements, allowing efficient resource allocation where each beam group uses resources appropriately for its designated coverage zone rather than uniformly across the entire system.

Inventive Principle:
Principle #3Local quality

3Reliability

If beam sweeping frequency is increased to improve terminal connection reliability, then the connection reliability is improved, but the power consumption and resource waste increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidenergy waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements periodic beam sweeping by alternately performing sweeping operations on different beam groups in a periodic manner. Instead of continuously sweeping all beams at high frequency, the system periodically switches between beam groups, maintaining connection reliability through regular updates while reducing overall power consumption and energy waste by avoiding redundant high-frequency sweeping of all beams.

Inventive Principle:
Principle #19Periodic action
