Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If beam tables are used to accommodate terminals in 5G mobile communications system, then wireless communication service can be provided to terminals, but the number of accommodated terminals is limited by beam table resource capacity

Engineering Contradiction:

Improvenumber of accommodated terminalsVSAvoidbeam table resource capacity

Core Design Contradiction:

Quantity of substanceVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic beam table management by periodically determining which terminals are movable between beam tables and reallocating them based on current system conditions. This dynamic approach allows the system to adapt terminal accommodation capacity to changing wireless quality and congestion conditions, effectively increasing the number of terminals that can be served without requiring additional fixed beam table resources.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the allocation parameters of beam tables by adjusting which terminals are assigned to which beam tables based on reception quality measurements and congestion levels. By changing terminal assignments rather than beam table structures, the system optimizes resource utilization and can accommodate more terminals within the existing beam table capacity constraints.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If conventional beam allocation techniques are used, then beam control with directivity is achieved, but high-quality service to user is hindered when optimal beam assignment is not possible

Engineering Contradiction:

Improveservice qualityVSAvoidbeam assignment optimization

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements feedback mechanisms by measuring reception quality for terminals in each beam table and using this information to determine movable terminals and perform reallocation. This feedback loop ensures that terminals are continuously assigned to optimal beam tables, maintaining high service quality even as system conditions change, thereby resolving the contradiction between service reliability and assignment optimization.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary determination of movable terminals based on reception quality measurements before executing reallocation. This preliminary action allows the system to proactively optimize beam assignments before service quality degrades, ensuring continuous high-quality service without requiring complex real-time optimization operations.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If beam tables are managed with fixed terminal assignments, then system operation is simplified, but terminal mobility between beam tables is restricted

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements periodic beam table management where the system determines movable terminals and performs reallocation at regular intervals. This periodic approach maintains operational simplicity by using standardized procedures while enabling terminal mobility between beam tables based on changing conditions, thus resolving the contradiction between ease of operation and terminal mobility.

Inventive Principle:

Principle #19Periodic action

AI summary

A wireless communications device configured to perform wireless resource management at a base station that performs wireless communication with a plurality of terminals by a predetermined beam, includes a memory storing therein a plurality of beam tables set with the terminals accommodated by a plurality of beams, and a processor connected to the memory and configured to manage the beam tables. The processor, during system operation, determines a movable terminal that, of the terminals, is movable between the beam tables and determines another beam table that, of the beam tables, is capable of accommodating the movable terminal. The processor moves the moveable terminal to the other beam table and adjusts a number of the terminals accommodated by each of the beam tables.
