Solution Overview

Problem

Wireless communication devices operating in low-capability mode struggle with efficient frame reception, particularly when they cannot receive frames other than initial control frames, leading to suboptimal performance in applications requiring high system throughput.

Innovation Solution

A wireless device generates an announcement indicating its capability to receive frames other than initial control frames, allowing peer devices to adjust transmission methods accordingly, such as transmitting management or data frames without initial control frames when possible, and switching to high-capability mode if necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless devices operate in low-capability mode to reduce device complexity and energy consumption, then ease of operation and energy efficiency improve, but frame reception capability deteriorates as devices cannot receive frames other than initial control frames

Engineering Contradiction:

Improveease of operationVSAvoidframe reception capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic capability indication where the wireless device can announce its reception capability status (capable or not capable) to peer devices. This allows the system to adapt frame transmission methods dynamically based on the receiving device's current state, enabling seamless transitions between low-capability and full-capability operation modes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the wireless device by introducing capability mode indicators that can be set to different states (capable/not capable of receiving frames). This parameter change enables the system to adjust transmission protocols appropriately, allowing the device to operate efficiently in low-capability mode when appropriate while maintaining ability to receive full frames when needed.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If wireless devices in low-capability mode transmit only initial control frames to simplify communication, then device complexity reduces, but system throughput deteriorates due to inability to exchange management and data frames efficiently

Engineering Contradiction:

Improvedevice complexityVSAvoidsystem throughput

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent segments the frame transmission process into different capability modes. In low-capability mode, only initial control frames are exchanged through simplified protocols. When full capability is needed, the device can indicate its ability to receive and process complete management and data frames, enabling efficient multi-frame exchanges for high-throughput applications.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wireless device is designed with universal functionality to operate in multiple capability modes. It can announce its capability status and switch between simplified low-capability operation and full-capability frame exchange, making it adaptable to different application requirements from simple control signaling to high-throughput data transmission.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Loss of information

If peer devices always transmit full management and data frames to ensure complete information exchange, then information completeness improves, but energy consumption increases due to unnecessary transmissions to low-capability devices

Engineering Contradiction:

Improveinformation completenessVSAvoidenergy consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

The patent implements a feedback mechanism where the receiving wireless device announces its capability status (able or unable to receive frames other than initial control frames). Peer devices use this feedback information to adjust their transmission strategy, sending only initial control frames to devices in low-capability mode and full management/data frames to devices capable of receiving complete frames, thereby optimizing energy efficiency while maintaining information completeness.

Inventive Principle:

Principle #23Feedback

4Adaptability or versatility

If wireless devices switch to high-capability mode to receive all frame types, then frame reception capability improves, but energy consumption and device complexity increase

Engineering Contradiction:

Improveframe reception capabilityVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent enables dynamic switching between low-capability and high-capability modes based on actual communication needs. Devices can operate in energy-efficient low-capability mode for simple control exchanges and switch to full-capability mode only when management or data frame reception is required, optimizing the balance between reception capability and energy consumption.

Inventive Principle:

Principle #15Dynamics
