Collocated Wireless Radio Timing Coordination for Aperiodic Activity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for handling activity of collocated wireless radios in wireless devices are limited in efficiently managing resource conflicts and avoiding contention due to aperiodic activity, as they fail to predict such random activity effectively.
Innovation Solution
Implementing systems and methods to predict wireless activity by sharing timing information between collocated radios, allowing one radio to schedule its activity to avoid conflicts with subsequent transmission events, using pre-computed timing information to enhance scheduling precision.

Engineering Contradiction Analysis
1Reliability
If conventional scheduling techniques are used for collocated wireless radios, then device complexity is reduced, but resource conflicts and contention increase due to inability to predict aperiodic activity
Solution Approach 1:
The patent applies preliminary action by having the first radio advance notification of its upcoming aperiodic activity to the second radio before the activity occurs. This allows the second radio to preemptively adjust its scheduling to avoid conflicts, transforming a reactive conflict-resolution problem into a proactive prevention problem. The timing information is shared in advance, enabling both radios to coordinate their transmission schedules before collisions occur.
2Measurement precision
If timing information sharing is implemented between collocated radios, then scheduling precision improves, but information transmission overhead increases
Solution Approach 1:
The patent extracts only the essential timing information needed for conflict avoidance from the complete radio transmission schedule. Instead of sharing all scheduling details, the system extracts and transmits only the critical parameters (such as start time, duration, and type of aperiodic activity) that enable the receiving radio to make accurate predictions and avoid conflicts. This selective information sharing reduces overhead while maintaining scheduling precision.

AI summary
Systems, methods, and devices predict activity of wireless devices. Methods include identifying one or more conditions indicating aperiodic activity will occur at a first radio, the first radio being a wireless radio compatible with a first wireless communications protocol, and receiving, at a second radio, timing information associated with the first radio via an interface between the first radio and the second radio, the second radio being a wireless radio compatible with a second wireless communications protocol, the first radio and the second radio being collocated in a wireless device. Methods also include scheduling wireless activity of the second radio based, at least in part, on the timing information.
