Solution Overview

Problem

Current wireless resource units and sub-channelization processes fail to meet the demands of future wireless communication systems, particularly in terms of high transmission rates, multi-carrier operations, diverse service types, and efficient frequency spectrum management.

Innovation Solution

A method for sub-channelization and resource mapping that adapts to different bandwidth and scheduling features, including multi-carrier operations, frequency multiplexing, and resource unit types, by performing permutation operations and mapping physical resource units into logical distributed and localized resource units, with parameters such as permutation sequences and frequency partitioning tailored to specific system requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional wireless resource units and sub-channelization processes are used, then system compatibility with existing standards is maintained, but frequency spectrum efficiency and scheduling flexibility are insufficient for future communication demands

Engineering Contradiction:
Improvescheduling flexibilityVSAvoidsub-channelization process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic sub-channelization by allowing the base station to determine different sub-channelization processes based on real-time scheduling needs and terminal capabilities. The system can switch between various sub-channelization modes (first and second sub-channelization processes) depending on the service type, bandwidth, and frequency multiplexing requirements, thereby achieving flexible adaptation without being locked into a single fixed process

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes key parameters of the sub-channelization process including the number of sub-channels, mapping relationships between physical and logical resource units, and frequency partitioning configurations. By adjusting these parameters based on system bandwidth features and scheduling features, the system optimizes frequency spectrum efficiency while maintaining compatibility with existing wireless communication standards

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If fixed resource mapping is used, then implementation simplicity is maintained, but support for diverse service types and multi-carrier operations is limited

Engineering Contradiction:
Improvesupport for diverse service typesVSAvoidimplementation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent creates a universal resource mapping framework that can handle multiple service types (voice, data, video), multiple carrier configurations (single carrier, multi-carrier contiguous, multi-carrier non-contiguous), and various bandwidths through a single set of mapping principles. The base station selects appropriate mapping configurations from a predefined set based on the service requirements, eliminating the need for separate dedicated mapping mechanisms for each service type

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

Solution Approach 2:

The patent segments the wireless resources into multiple physical resource units that can be independently mapped to logical resource units. This segmentation allows flexible combination of resource units to match different service requirements, enabling the system to support diverse services by assembling different configurations from the same basic segments

Inventive Principle:
Principle #1Segmentation

3Productivity

If single-carrier operation is used, then system complexity is reduced, but frequency spectrum utilization is insufficient for high transmission rates

Engineering Contradiction:
Improvetransmission rateVSAvoidmulti-carrier operation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple carriers into a unified resource mapping framework by establishing mapping relationships between physical resource units on different carriers and logical resource units. This allows the system to treat multi-carrier resources as a single pool for scheduling and resource allocation, achieving high transmission rates through carrier aggregation while managing complexity through a systematic mapping approach

Inventive Principle:
Principle #5Merging (Combining)
