Solution Overview

Problem

In future communication systems, terminal devices face challenges in selecting an appropriate numerology for transmitting signals, as fixed numerologies may not meet the requirements of different service types, limiting flexibility and efficiency.

Innovation Solution

A method and apparatus that allow terminal devices to determine a target numerology based on a mapping relationship between resource pools and basic numerologies, enabling flexible selection of numerologies for different services by acquiring and utilizing appropriate resource pools and transmission resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed numerology is allocated to the terminal device, then the resource pool can be simply configured, but the terminal device cannot meet the requirements of different service types that need different basic numerologies

Engineering Contradiction:
Improveadaptability to different service typesVSAvoidnumerology selection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the numerology dynamic by allowing the terminal device to select from multiple basic numerologies based on service requirements. Instead of a fixed numerology, the system dynamically adapts the numerology configuration to match different service types, achieving both adaptability and controlled complexity through standardized selection procedures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the numerology parameter by introducing multiple basic numerologies with different configurations. The terminal device can select appropriate numerology parameters (such as subcarrier spacing, cyclic prefix length) based on service type requirements, enabling flexible adaptation while maintaining systematic management through predefined options.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple resource pools with different numerologies are configured, then the terminal device can select appropriate numerology for different services, but the system complexity and resource pool configuration difficulty increase

Engineering Contradiction:
Improveflexibility in numerology selectionVSAvoidresource pool configuration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the resource pool into multiple subsets, each associated with a specific basic numerology. This segmentation allows the terminal device to select resources from the appropriate segment based on service requirements, reducing the complexity of numerology selection while maintaining flexibility. Each segment is independently configured but follows a standardized structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal resource pool structure that can serve multiple service types. By defining standardized basic numerologies and their corresponding resource pool segments, the system achieves multi-functionality where the same framework supports various services with different numerology requirements, reducing overall system complexity through standardization.

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