Solution Overview

Problem

Existing wireless communication systems face inefficiencies in transmitting sets of frames with common and duplicative bit sequences, leading to increased data sizes and power consumption.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If traditional wireless communication systems transmit sets of frames with common and duplicative bit sequences, then communication reliability is maintained, but data size increases and power consumption increases

Engineering Contradiction:
Improvepower consumptionVSAvoiddata size
Core Design Contradiction:
Loss of energyVSQuantity of substance

Solution Approach 1:

The patent extracts and removes duplicative bit sequences from frame transmissions by implementing flow-based compression. Common bit sequences are identified and eliminated through flow index assignment, reducing redundant data while maintaining communication reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Multiple frames with common bit sequences are merged into a single flow frame representation. By combining repetitive elements through flow index assignment, the system transmits only unique portions of data, reducing overall data size and power consumption.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of energy

If flow compression is applied to reduce MAC header sizes and data traffic, then power consumption decreases, but device complexity increases due to compression and decompression logic

Engineering Contradiction:
Improvepower consumptionVSAvoidcompression logic complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

Compression rules and flow indices are established in advance before data transmission begins. The system pre-defines compression parameters and flow management protocols, allowing devices to execute compression and decompression operations efficiently without complex real-time decision-making logic.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes parameters such as flow index assignment and compression ratios to optimize the balance between data reduction and processing complexity. By adjusting these parameters dynamically, the system achieves effective compression while keeping device complexity manageable.

Inventive Principle:
Principle #35Parameter changes

3Loss of energy

If flow frames are generated and transmitted to reduce data traffic, then power consumption is lowered, but latency may increase due to compression and decompression processing

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

Flow indices and compression parameters are prepared in advance, enabling rapid frame compression and decompression operations. This preliminary preparation reduces processing time during actual data transmission, minimizing latency while maintaining low power consumption.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous flow frame generation and transmission without interruption, keeping devices in efficient low-power states. By sustaining useful action continuously rather than through intermittent processing, the system reduces overall latency while maintaining energy efficiency.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

Logic may compress wireless communications frames and communicate compressed frames that do not include the duplicative bit sequences within the packet flow. Logic may include the compressed frames in flow frames. Logic may generate, encode, transmit, decode, parse, and interpret flow frames after a packet flow is created. Flow frames may comprise a flow frame control field, a compressed frame, and a frame sequence check. Logic may decompress the compressed flow frame based upon flow decompression rules associated with a flow index of the flow frame. Flow frames may include a duration field to set the network allocation vectors of other stations. And the frame sequence check may be generated based upon the entire flow frame.
