Collocated Radio Arbitration Handover for Low-Power Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collocated communication circuitry operating in overlapping or adjacent radio frequency spectrums experiences performance degradation, including reduced operating range and lower throughput, due to coexistence issues, and the constant power consumption of arbitration logic in battery-powered devices is a significant concern.
Innovation Solution
Implementing arbitration logic that can be shared among collocated communication subsystems through a handover and takeback protocol, allowing certain power domains to shut down during inactivity and switch between arbitration roles to conserve power, while maintaining throughput and quality of service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If arbitration logic is constantly active to manage radio access, then communication performance is improved, but power consumption increases
Solution Approach 1:
The arbitration logic transitions from a static always-on state to a dynamic state that can be activated or deactivated based on system conditions. The patent implements a mechanism where the first arbitration logic can be deactivated when a second arbitration logic is activated, allowing the system to adapt its arbitration capability to current communication needs while reducing power consumption during low-activity periods.
Solution Approach 2:
The system changes the operational state parameter of the arbitration logic from constantly active to conditionally active. By controlling the activation and deactivation states of different arbitration logics based on communication traffic patterns and system priorities, the patent optimizes the balance between maintaining communication performance and reducing power consumption.
2Adaptability or versatility
If multiple radios operate simultaneously in overlapping RF spectrums, then communication versatility is improved, but coexistence issues arise causing reduced operating range and throughput
Solution Approach 1:
The patent segments the arbitration function into multiple independent arbitration logics (first arbitration logic and second arbitration logic), each capable of managing specific radio communications. This segmentation allows different arbitration strategies to be applied to different radios or communication types, enabling better coexistence management in overlapping spectrums while maintaining overall system versatility.
Solution Approach 2:
The arbitration logic acts as an intermediary between multiple radios operating in overlapping spectrums. By introducing this mediating layer that can activate or deactivate based on system conditions, the patent enables coordinated access management that resolves coexistence issues and maintains throughput while preserving the ability to support multiple communication protocols simultaneously.

AI summary
An example system and method, during operation of first communication circuitry in a first operating mode comprising first power consumption, uses the first communication circuitry to perform packet arbitration for wireless communications by the first communication circuitry, second communication circuitry, and third communication circuitry. During operation of the first communication circuitry in a second operating mode comprising second power consumption, the example system and method uses the second communication circuitry to perform packet arbitration for wireless communications by the second communication circuitry and a third communication circuitry.
