Communication Apparatus Beacon Cycle State Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication devices in power saving mode face challenges in balancing power consumption with data throughput and loss, as they do not effectively adapt to varying beacon transmission cycles and data availability, leading to inefficient state switching between Awake and Doze states.
Innovation Solution
A communication apparatus that switches between operating and hibernation states based on the transmission cycle of control information, keeping the operating state for a specific period corresponding to a predetermined percentage of the beacon cycle to prevent data loss and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the apparatus keeps the Awake state for a long time to prevent data loss, then data reliability is improved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts the Awake state duration based on the beacon interval. Instead of using a fixed predetermined time, the apparatus calculates the keep period as a percentage (e.g., 50-90%) of the actual beacon interval, allowing the system to adapt to different beacon transmission cycles and optimize both data reliability and power consumption
Solution Approach 2:
The patent changes the parameter of Awake state duration from a fixed predetermined time to a variable time calculated as a percentage of the beacon interval. This parameter change allows the system to scale the Awake duration proportionally with the beacon interval, preventing data loss while optimizing power consumption for different network configurations
2Productivity
If the apparatus transits to the Awake state frequently to receive beacons, then data throughput is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by keeping the Awake state for only a calculated portion (percentage) of the beacon interval rather than the entire interval. This partial Awake period is sufficient to receive data after beacon transmission while avoiding unnecessary prolonged Awake states that would waste power
Solution Approach 2:
The patent utilizes periodic beacon transmission cycles to structure the Awake/Doze state transitions. The apparatus synchronizes its state switching with the periodic beacon interval, entering Awake state at appropriate intervals to receive beacons and data, then transitioning to Doze state to conserve power during periods when no communication is expected
3Device complexity
If the apparatus uses a fixed predetermined time for Awake state, then implementation simplicity is improved, but adaptability to different beacon intervals deteriorates
Solution Approach 1:
The patent changes the Awake state duration parameter from a fixed predetermined value to a variable calculated as a percentage of the beacon interval. This allows the system to automatically adapt to different beacon intervals (e.g., 100ms, 200ms, 500ms) without requiring manual reconfiguration or complex lookup tables, maintaining implementation simplicity while improving adaptability

AI summary
An operating state of a communication unit of a communication apparatus is kept for a keep period in accordance with a transmission cycle of control information transmitted by another communication apparatus. The communication apparatus wirelessly communicates with the other communication apparatus in the operating state. If the keep period elapses, the communication unit is switched from the operating state to a hibernation state. The communication apparatus does not communicate with the other communication apparatus in the hibernation state.
