Dual-Mode WLAN Device Data Loss Reduction

The patent applies preliminary action by checking whether the current interval is a STA interval before deferring data requests. When the device is in AP mode and needs to request data from an external AP, it proactively determines whether the next available interval will be a STA interval, and only defers the request if confirmed. This prevents data loss by avoiding deferred requests that would cross mode transition boundaries, while still enabling dual-mode operation through TDM.

The patent uses feedback mechanisms by continuously monitoring the current operating mode and the timing of deferred data requests. The device checks whether deferred requests would cross mode transition boundaries and adjusts the deferral decision accordingly. This feedback-based approach ensures that data requests are only deferred when necessary to maintain transmission continuity, minimizing unnecessary delays and optimizing throughput while preventing data loss.

The patent applies dynamics by making the mode switching timing adaptive rather than fixed. The device dynamically adjusts mode transition timing based on deferred data request status and beacon reception timing. When data requests are deferred, the mode switching is delayed to allow completion in the current mode. The system continuously synchronizes with beacon timing and adjusts transitions accordingly, ensuring both reliable data request completion and maintained beacon synchronization through flexible, real-time adjustments.
