Timing Offset Compensation for Inter-Link Interference

The patent applies preliminary action by determining the timing offset between uplink and downlink signals before performing interference cancellation. The victim device calculates the time offset between the first signal (one link direction) and the interfering signal (other link direction), then uses this offset to align the signals in time before cancellation processing. This preliminary timing alignment ensures that the interference cancellation operates on properly synchronized signals, resolving the technical contradiction between achieving effective cancellation and maintaining timing accuracy.

The patent applies self-service by enabling the victim device to autonomously determine and compensate for timing offsets without requiring complex network coordination or additional infrastructure. The device independently measures the time offset between signals from different link directions, calculates the appropriate compensation, and applies it locally to achieve effective interference cancellation. This self-contained approach improves transmission reliability while avoiding the need for complex centralized timing management systems.
