LE Audio Time Scheduling for Overlapping Multi-Stream Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth Classic audio consumes high power and has limitations on the number of connectable devices, while Low-Energy (LE) audio supports multi-stream functions but faces challenges in overlapping time resources for multiple audio services.
Innovation Solution
An electronic device determines whether a second time resource for a second audio service can be set to overlap or not with a first time resource, adjusts quality or sets non-overlapping time resources, and performs audio services accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth Classic audio is used, then audio transmission is reliable, but power consumption is high and the number of connectable devices is limited
Solution Approach 1:
The patent changes the fundamental communication parameter from Bluetooth Classic to Bluetooth Low Energy (BLE), enabling the device to achieve both low power consumption and support for multiple connectable devices while maintaining audio transmission functionality through LE Audio technology
2Adaptability or versatility
If LE audio multi-stream function is used to transmit audio to multiple devices, then the number of connectable devices increases, but time resource management becomes complex due to overlapping time resources
Solution Approach 1:
The patent segments time resources into distinct time windows for different audio services, dividing the time domain into non-overlapping intervals that are independently managed. This segmentation approach simplifies the management of multiple audio streams by ensuring that each time window is dedicated to a specific audio service without resource conflicts
Solution Approach 2:
The patent implements dynamic time window allocation where the system can flexibly adjust and reconfigure time resources for different audio services based on current operational needs. This dynamic management allows the device to adaptively handle multiple audio streams while maintaining efficient resource utilization and avoiding overlapping conflicts
3Reliability
If time resources for multiple audio services are set to not overlap, then resource conflict is avoided, but time resource utilization efficiency decreases
Solution Approach 1:
The patent implements periodic time windows for audio service transmission, where each audio service is allocated specific periodic time intervals. This periodic structure allows the system to efficiently reuse time resources across different audio services in a cyclic manner, achieving both conflict avoidance and high utilization efficiency through structured periodic allocation

AI summary
A method for providing audio includes the steps of: determining whether a second time resource, in which a second audio service is performed, is capable of being set so as not to overlap a first time resource, in which a first audio service is performed; setting the second time resource so that at least a portion of the first time resource overlaps at least a portion of the second time resource based on a determination that the first time resource and the second time resource are not capable of being set so as not to overlap; and performing the second audio service based on the set second time resource.
