Bridge Relay for Unsynchronized Periodic Advertisement Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing in-band communications between central devices and peripheral devices, particularly in scenarios involving unsynchronized periodic advertisement (PAwR) trains, leading to potential conflicts and inefficiencies.
Innovation Solution
Implementing a peripheral device as a bridge to relay communications between unsynchronized PAwR trains of central devices, utilizing timing difference-aware subframe allocation to synchronize and avoid conflicts, thereby facilitating efficient in-band central-to-central communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If direct communication between central devices is used, then communication simplicity is maintained, but communication coverage is limited and conflicts with PA trains occur
Solution Approach 1:
The patent introduces peripheral devices as intermediary bridge nodes to relay communications between central devices. These bridge peripheral devices receive communications from one central device and forward them to another central device, thereby extending communication coverage beyond direct range while managing PA train conflicts through the intermediary routing path.
2Area of stationary object
If peripheral devices are used as bridges, then communication coverage is extended, but timing synchronization becomes complex due to timing drift
Solution Approach 1:
The patent performs preliminary timing drift compensation by calculating timing differences between PA trains and pre-adjusting transmission timing parameters before communication occurs. The system determines timing drift characteristics in advance and configures bridge peripheral devices with appropriate timing offsets to prevent synchronization issues during actual communication.
Solution Approach 2:
The patent implements dynamic timing adjustment mechanisms where the system continuously monitors and adapts timing parameters based on observed drift between PA trains. Bridge peripheral devices dynamically adjust their transmission timing to maintain synchronization despite drift, allowing the system to adapt to changing conditions rather than relying on fixed timing configurations.
3Reliability
If timing drift is not compensated, then system complexity is reduced, but communication reliability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where bridge peripheral devices monitor timing relationships between PA trains and continuously report timing drift characteristics back to the system. This feedback enables the system to detect and correct timing issues, maintaining communication reliability through ongoing adjustment rather than one-time configuration.

AI summary
Systems and techniques are provided for wireless communications. For example, a process can include receiving, from a first network entity a request to identify one or more additional network entities available for communication with a wireless communication device. A process can include transmitting, to a second network entity included in the one or more additional network entities, timing information indicative of a difference between first synchronization information associated with the first network entity and second synchronization information associated with the second network entity.
