Electronic Device BLE Timing Coordination for Overlapping Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication environments, overlapping time resources between multiple Bluetooth low energy (BLE) connections can lead to reduced reception performance in audio devices, particularly when multiple external devices are transmitting audio data simultaneously.
Innovation Solution
An electronic device equipped with BLE communication circuitry identifies overlapping time resources between multiple communication links and adjusts these resources by transmitting request signals to the external devices to synchronize and optimize time allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple BLE communication links are established simultaneously with different master devices, then communication versatility and connectivity are improved, but reception performance deteriorates due to overlapping time resources
Solution Approach 1:
The slave device dynamically adjusts its reception timing for different master devices based on detected overlapping patterns. The device monitors time resource usage across multiple communication links and adaptively modifies synchronization parameters to avoid conflicts, enabling simultaneous maintenance of multiple connections without performance degradation
Solution Approach 2:
The invention changes the timing parameters of communication links by transmitting adjustment requests to master devices. The slave device modifies reception timing parameters (such as connection interval, latency, or synchronization offsets) to eliminate overlaps, thereby resolving the contradiction between maintaining multiple connections and ensuring reliable reception
2Reliability
If time resources are adjusted to prevent overlap between multiple communication links, then reception performance is improved, but communication complexity increases
Solution Approach 1:
The slave device autonomously detects overlapping time resources and generates appropriate adjustment requests without requiring complex centralized coordination. The device monitors its own communication patterns, identifies conflicts, and initiates timing adjustments independently, reducing the need for complex external resource management infrastructure
Solution Approach 2:
The invention implements a feedback mechanism where the slave device monitors reception quality and time resource usage, then uses this information to adjust timing parameters. By continuously detecting overlaps and responding with adjustment requests, the system maintains optimal performance through automated feedback-driven optimization rather than complex pre-planned resource allocation

AI summary
An electronic device having a communication circuitry, at least one memory, and at least one processor is provided. The processor is configured to identify a first communication link with a first external electronic device operating as a first master device with respect to the electronic device and a second communication link with a second external electronic device operating as a second master device with respect to the electronic device, identify whether at least a portion of first time resources used for the first communication link overlap with at least portion of second time resources used or to be used for the second communication link and transmit one of a first request signal for adjusting the first time resources and a second request signal for adjusting the second time resources based on identifying that at least the portion of the first time resources overlap with at least the portion of the second time resources.
