Innovation Solution

A method and apparatus for selecting and transmitting allocation schemas for wireless resources, including generating an allocation message with identifiers and parameters for wireless communication devices, which allows for efficient allocation of 26-tone and 242-tone blocks, 20 MHz, 40 MHz, and 80 MHz schemas, indicating user sharing and parameters, to optimize resource allocation and reduce interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple devices share the same wireless network, then network coverage and accessibility are improved, but communication congestion and interference increase

Engineering Contradiction:
Improvenetwork coverageVSAvoidcommunication efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the wireless network into multiple virtual channels or logical networks, allowing simultaneous transmissions on different segments without interference. This enables multiple devices to share the network while maintaining individual communication paths, thus improving overall communication efficiency despite increased device density.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces additional dimensions for resource allocation beyond traditional time and frequency domains, such as spatial dimensions through MIMO (Multiple Input Multiple Output) technology. By utilizing multiple antennas and spatial streams, the system creates parallel communication paths that reduce congestion and interference while maintaining network coverage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If wireless resources are allocated to multiple users simultaneously, then network throughput is improved, but resource allocation complexity increases

Engineering Contradiction:
Improvenetwork throughputVSAvoidallocation management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic resource allocation where allocation parameters are continuously adjusted based on real-time network conditions, user requirements, and channel quality. This dynamic approach allows the system to optimize throughput by allocating resources to users with the best channel conditions while automatically adapting to changing conditions, reducing the need for complex manual management.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent incorporates feedback mechanisms where users report channel quality, buffer status, and reception conditions back to the base station. This feedback enables automatic adjustment of allocation parameters, allowing the system to maintain high throughput through adaptive modulation, coding, and resource allocation without requiring complex centralized control.

Inventive Principle:
Principle #23Feedback

3Reliability

If transmission power is increased to overcome interference, then signal reliability is improved, but energy consumption and interference to other users increases

Engineering Contradiction:
Improvesignal reliabilityVSAvoidtransmission energy consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies local quality by allocating different transmission power levels to different users and channels based on their specific requirements and channel conditions. Users with good channel conditions receive lower power allocations, while users in poor conditions receive targeted power boosts only where needed. This localized approach maintains signal reliability for each user while minimizing overall energy consumption and reducing interference to other users.

Inventive Principle:
Principle #3Local quality
