Bluetooth Channel Information Sharing for Multi-Link Power Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Bluetooth network environments, multi-connection scenarios lead to increased power consumption and inefficient radio resource usage due to the transmission of data packets across multiple links.
Innovation Solution
An electronic device with a wireless communication circuit, processor, and memory executes instructions to establish links with external devices, determine whether to share channel information, and transmit this information to optimize data packet transmission, thereby reducing radio resource consumption and enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-connection is established to transmit data packets to multiple external devices, then communication capability is improved, but power consumption increases and radio resource efficiency decreases
Solution Approach 1:
The patent merges channel information from multiple links into shared channel information that can be utilized by all connected devices. By establishing a shared channel through the second link, the system allows multiple external devices to access communication resources efficiently without requiring separate dedicated channels for each device, thus reducing overall power consumption while maintaining multi-device communication capability
Solution Approach 2:
The shared channel information established through the second link serves multiple purposes: it enables communication with the second external device directly, and simultaneously provides channel estimation capabilities for monitoring communications with the first external device. This multi-functional use of a single channel reduces the need for multiple separate communication pathways, thereby improving radio resource efficiency

Solution Approach 2:
The second link acts as an intermediary that carries shared channel information which then benefits both the second external device (for direct communication) and the first external device (for channel estimation and monitoring). This intermediary channel optimizes radio resource utilization by serving multiple communication purposes through a single established link
