Solution Overview

Problem

Current multi-band communication devices do not effectively utilize the capacity of multiple radio modules, leading to inefficiencies in data transmission across different frequency bands.

Innovation Solution

A method where a source node divides a data stream into multiple sub-streams, each modulated using appropriate techniques for different radio modules operating in distinct frequency bands, allowing simultaneous transmission and reception across these bands by both source and destination nodes, which then combine the sub-streams to form the original data stream.

Engineering Contradictions & Design Principles

1Productivity

If multiple radio modules operate independently in different frequency bands, then each module can communicate in its designated band, but the overall data transmission capacity is not effectively utilized

Engineering Contradiction:

Improvedata transmission capacityVSAvoidmultiple independently-operating radio modules

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The data stream is segmented into multiple sub-streams, with each sub-stream being transmitted through a different radio module operating in a specific frequency band. This segmentation allows the system to utilize the capacity of multiple radio modules simultaneously, transforming the limitation of independent operation into an advantage for parallel data transmission.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent combines multiple independently-operating radio modules into a unified communication system where data is split across modules and recombined at the destination. This merging approach effectively aggregates the transmission capacity of all radio modules while maintaining their operational independence, resolving the contradiction between utilizing multiple modules and managing system complexity.

Inventive Principle:

Principle #5Merging (Combining)

2Productivity

If a hand-off procedure switches transmission from one radio module to another, then communication can continue across frequency bands, but transmission efficiency is reduced due to sequential operation

Engineering Contradiction:

Improvetransmission efficiencyVSAvoidhand-off continuity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system maintains continuous data transmission by dividing the data stream into sub-streams that are transmitted simultaneously through multiple radio modules. This eliminates the need for sequential hand-off procedures, as all radio modules operate in parallel throughout the transmission process, ensuring both high efficiency and continuous communication.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent implements a dynamic data stream splitting mechanism that can adaptively allocate data sub-streams to different radio modules based on their current operational status and capacity. This dynamic approach allows the system to optimize transmission efficiency while maintaining reliability, as data can be rerouted through available modules without interrupting overall communication.

Inventive Principle:

Principle #15Dynamics

3Productivity

If only one radio module is operated at a time, then device operation is simplified, but the capacity of multiple radio modules remains underutilized

Engineering Contradiction:

Improveradio module capacity utilizationVSAvoidradio module operation management

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system implements self-service mechanisms where the data stream is automatically divided into sub-streams and allocated to appropriate radio modules based on their capabilities and current state. This self-organizing approach allows multiple radio modules to operate in parallel without requiring complex manual coordination, thereby utilizing their full capacity while maintaining operational simplicity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent creates a universal data transmission framework that can operate with any combination of available radio modules. This multi-functional approach allows the system to automatically utilize whichever radio modules are currently active or available, maximizing capacity utilization without requiring dedicated control mechanisms for each specific module configuration.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Techniques are provided for communicating a data stream in a wireless communication network. A source divides the data stream into a first data sub-stream and a second data sub-stream. The first data sub-stream can be modulated using a first modulation technique to generate a first modulated data sub-stream, and the second data sub-stream can be modulated using a second modulation technique to generate a second modulated data sub-stream. A destination receives the first data sub-stream over a first frequency band, and receives the second data sub-stream over a second frequency band. The destination demodulates the first data sub-stream using a first demodulation technique to generate a first demodulated data sub-stream, and demodulates the second data sub-stream using a second demodulation technique to generate a second demodulated data sub-stream. The destination then combines the first demodulated data sub-stream and the second demodulated data sub-stream to generate the data stream.
