Solution Overview

Problem

Existing wireless communication technologies face inefficiencies in data transmission due to the lack of explicit payload format indication, leading to difficulties in decoding payloads of different formats and resulting in low spectral efficiency and reduced network throughput.

Innovation Solution

The proposed solution involves generating and transmitting data frames that include a payload format identifier bit, a retransmission identifier bit, and optional serial numbers or bitmap information to indicate payload formats and retransmission information, allowing for efficient decoding and combination analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If no explicit payload format indication is provided in the data frame, then the data frame structure remains simple, but the receiver cannot efficiently decode payloads of different formats leading to low spectral efficiency

Engineering Contradiction:
Improvepayload format identification accuracyVSAvoiddata frame structure complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The payload format indication is segmented into a dedicated identifier bit or field within the data frame structure. This allows the receiver to clearly distinguish different payload formats (e.g., initial transmission vs. retransmission, different modulation schemes) without ambiguity, resolving the contradiction between identification accuracy and structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An intermediary payload format identifier bit is introduced as a mediator between the transmitter and receiver. This bit explicitly indicates the payload format type, enabling the receiver to correctly interpret the payload without requiring complex analysis of the payload content itself, thus maintaining structural simplicity while improving identification accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If retransmission data frames use the same payload format as initial transmission, then the data frame structure remains consistent, but combination analysis between initial and retransmission frames becomes difficult

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidpayload format management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The payload format is made dynamic by introducing a retransmission identifier bit that can take different values for initial transmission versus retransmission. This allows the system to adapt the payload format according to the transmission stage, enabling effective combination analysis while maintaining manageable structural complexity through a simple bit indicator.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The payload format parameters are changed based on the transmission type by using the retransmission identifier bit. This bit signals whether the payload follows the initial transmission format or the retransmission format, allowing the receiver to correctly apply combination analysis techniques without requiring complex format detection, thus improving transmission efficiency while keeping structure manageable.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If no retransmission identifier bit is included, then the data frame header remains compact, but the receiver cannot distinguish between initial transmission and retransmission frames

Engineering Contradiction:
Improvereception accuracyVSAvoidheader structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The retransmission identification function is extracted from the payload content and placed into a dedicated identifier bit in the header. This extraction allows the receiver to quickly determine whether the frame is an initial transmission or retransmission without analyzing the payload, improving reception accuracy while adding minimal header complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical analysis of payload content to determine transmission type is replaced by a simple bit check of the retransmission identifier. This substitution significantly improves reception accuracy by providing explicit information, while the added header complexity is minimal—only a single bit or small field.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
