Solution Overview

Problem

Existing wireless communication technologies face challenges in efficiently transmitting data packets with large volumes without incurring excessive overheads due to headers and resource limitations.

Innovation Solution

A communication method that jointly sends and receives data packets across multiple time domain resources within a periodic resource framework, eliminating the need for separate headers on each resource and utilizing guard intervals for signal conversion, thereby improving resource utilization and transmission efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If data packets are transmitted using traditional per-resource header allocation, then each resource can be independently managed, but extra overheads from headers increase and resource utilization decreases

Engineering Contradiction:

Improveresource utilizationVSAvoidheader overhead

Core Design Contradiction:

Loss of energyVSQuantity of substance

Solution Approach 1:

The patent merges multiple time domain resources into a single codeblock for data transmission. Instead of adding separate headers to each resource, a single header is added to the entire codeblock, thereby reducing header overhead and improving resource utilization while maintaining independent resource management capabilities

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The codeblock structure serves multiple functions: it consolidates data from multiple time domain resources, provides a single header for all resources, enables flexible resource allocation, and maintains compatibility with existing communication protocols, thereby improving overall system efficiency

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Quantity of substance

If data volume is limited by single resource size, then transmission simplicity is maintained, but larger data packets cannot be transmitted efficiently

Engineering Contradiction:

Improvedata volumeVSAvoidtransmission structure

Core Design Contradiction:

Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent segments a large data packet into multiple codeblocks, where each codeblock can be transmitted across multiple time domain resources. This segmentation allows large data volumes to be transmitted efficiently while maintaining manageable transmission structures through the codeblock organization

Inventive Principle:

Principle #1Segmentation

3Productivity

If separate headers are added to each time domain resource, then resource independence is maintained, but transmission efficiency decreases due to repeated overhead

Engineering Contradiction:

Improvetransmission efficiencyVSAvoidheader repetition

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The patent combines multiple time domain resources into a single codeblock with a single header, eliminating the need for repeated headers across resources. This merging approach significantly improves transmission efficiency by removing redundant overhead while maintaining the ability to manage multiple resources independently

Inventive Principle:

Principle #5Merging (Combining)
