Solution Overview

Problem

In wireless communication networks, devices face challenges in efficiently scheduling transmissions between multiple stations due to individual resource constraints and power consumption issues when announcing and following multiple schedules, leading to increased power usage and potential conflicts.

Innovation Solution

Implementing a method where stations announce availability and no-availability windows, allowing for the generation of an adjusted communication schedule that merges and adjusts based on feedback from other stations, reducing power consumption and avoiding conflicts by specifying time slots for communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If devices follow multiple individual communication schedules from different stations, then communication coverage and connectivity are improved, but power consumption increases

Engineering Contradiction:
Improvecommunication coverageVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent merges multiple individual communication schedules from different stations into a single aggregated communication schedule. Instead of maintaining separate schedules for each station, the system combines them into one unified schedule that covers all communication requirements, thereby reducing the power consumption associated with managing and following multiple schedules while maintaining comprehensive communication coverage.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If devices announce and follow multiple communication schedules, then communication flexibility is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication flexibilityVSAvoidschedule management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple communication schedules into a single aggregated schedule, simplifying the device's schedule management functionality. Instead of implementing complex logic to handle multiple independent schedules, the device only needs to manage one unified schedule, thereby reducing device complexity while preserving communication flexibility through the aggregated schedule's ability to accommodate multiple stations.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If communication schedules are announced without coordination, then individual station autonomy is maintained, but schedule conflicts increase

Engineering Contradiction:
Improvestation autonomyVSAvoidschedule conflict avoidance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where stations provide availability information to the aggregated schedule coordinator. This feedback allows the system to identify and resolve schedule conflicts while maintaining station autonomy, as each station's constraints are incorporated into the aggregated schedule through structured feedback rather than centralized control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary coordination by aggregating schedules before actual communication occurs. By combining and resolving schedules in advance, the system prevents conflicts from arising during actual communication operations, thereby maintaining reliability while preserving station autonomy through the preliminary coordination process.

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided are systems and methods for a network station identifying a communication schedule announced by a first wireless network station, determining that the first wireless network station has a right to generate an adjusted communication schedule, and causing transmission of an availability window schedule to the first wireless network station. The availability window schedule indicates one or more time slots during which communication with the wireless network station is inhibited.
