Non-periodic synchronization boundaries for wireless channel access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in maintaining efficient access to wireless channels, particularly in unlicensed frequency bands, due to alignment and overlap of periodic synchronization boundaries with other channel access modes, leading to communication delays and reduced access opportunities for LBE synchronous nodes.
Innovation Solution
Implementing non-periodic synchronization boundaries determined using pseudorandom number generators, which are coordinated between wireless communication devices to prevent alignment with fixed frame periods of other modes, allowing for variable and randomized synchronization intervals.

1Reliability
If periodic synchronization boundaries are used for channel access, then synchronization is maintained and coordination between nodes is simplified, but alignment and overlap with other channel access modes occurs causing communication delays and reduced access opportunities
Solution Approach 1:
The patent applies dynamics by transitioning from fixed periodic synchronization boundaries to flexible non-periodic synchronization boundaries. The synchronization boundaries are no longer constrained to regular intervals but can adapt their timing dynamically, allowing them to avoid alignment conflicts with other channel access modes while maintaining synchronization coordination between nodes.
Solution Approach 2:
The patent changes the temporal parameter of synchronization boundaries from periodic to non-periodic intervals. By modifying the time parameter from fixed to variable intervals, the system avoids the alignment overlap problem that occurs with periodic boundaries, thereby reducing communication delays and improving access opportunities for LBE synchronous nodes.
2Ease of operation
If periodic synchronization boundaries are used for channel access, then coordination between nodes is simplified, but access opportunities for LBE synchronous nodes are reduced due to overlap with other channel access modes
Solution Approach 1:
The system maintains coordination simplicity through dynamic adaptation. Rather than requiring complex static scheduling to avoid overlaps, the non-periodic synchronization boundaries dynamically adjust their timing to prevent conflicts with other channel access modes, thereby improving access opportunities while keeping coordination mechanisms relatively simple.
Solution Approach 2:
The patent applies preliminary anti-action by proactively designing non-periodic synchronization boundaries that prevent alignment overlap with other channel access modes before conflicts occur. This anticipatory approach avoids the access opportunities loss that would result from periodic boundary alignment, allowing LBE synchronous nodes to access the channel more effectively.
3Productivity
If non-periodic synchronization boundaries are implemented, then access opportunities and communication efficiency are improved, but system complexity increases due to coordination requirements
Solution Approach 1:
The patent uses dynamics to manage complexity by implementing flexible non-periodic synchronization boundaries that adapt to channel conditions and node requirements. This dynamic approach improves access efficiency while distributing the coordination complexity across multiple nodes rather than requiring centralized complex scheduling, as each node can independently determine its synchronization boundary timing.
