Solution Overview

Problem

Future wireless communication systems face challenges with high frequencies, particularly in millimeter wave communication, due to issues related to data rates, processing speed, and latency, which are not adequately addressed by current systems.

Innovation Solution

Implementing a method for receiving and transmitting data signaling with an unspecified duration, using stop indications based on error coding, identifiers, and signaling sequences to manage data transmission efficiently, allowing continuous transmission until a stop indication is received, which can be signaled through various methods including separate channels or included in data signaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data signaling with unspecified duration is used, then data transmission efficiency is improved, but control signaling overhead increases

Engineering Contradiction:

Improvedata transmission efficiencyVSAvoidcontrol signaling overhead

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the essential stop indication functionality from the data signaling structure. By using a separate stop indication channel that transmits only when needed (when data signaling duration is unspecified), the system reduces control overhead while maintaining the ability to efficiently handle continuous data transmission. The stop indication is separated from the data signaling itself, allowing the data channel to operate continuously without constant control signaling.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If stop indication is transmitted separately from data signaling, then reception reliability is improved, but transmission time increases

Engineering Contradiction:

Improvereception reliabilityVSAvoidtransmission time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system implements periodic or event-driven transmission of stop indications rather than continuous transmission. The stop indication is transmitted only when the data signaling duration is unspecified or when a stop condition occurs, creating a periodic action pattern that maintains reception reliability while minimizing transmission time. This is achieved through the stop indication channel that activates only when necessary, rather than continuously monitoring or transmitting.

Inventive Principle:

Principle #19Periodic action

3Adaptability or versatility

If data signaling indication indicates unspecified duration, then flexibility is improved, but processing complexity increases

Engineering Contradiction:

ImproveflexibilityVSAvoidprocessing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a stop indication channel as an intermediary mechanism that simplifies the processing of unspecified duration data signaling. Instead of the receiver having to continuously determine when data signaling should stop based on complex analysis, the stop indication channel provides clear, explicit stop signals. This intermediary layer reduces processing complexity at the receiver while maintaining the flexibility of unspecified duration transmission.

Inventive Principle:

Principle #24Intermediary (Mediator)
