Multi-Link WLAN STR Channel Sensing for Adjacent-Band Interference

The patent applies preliminary action by performing carrier sensing operations at carefully timed intervals after transmission ends, rather than immediately. The transmitting station determines a specific timing window based on the end time of its transmission, and only performs carrier sensing within this predetermined window. This allows the system to prepare for channel access in advance while avoiding the interference period that occurs immediately after transmission, thus resolving the contradiction between efficiency and reliability.

The patent applies segmentation by dividing the multi-link channel management into independent, manageable units. Each link is managed separately with its own transmission end time tracking and carrier sensing timing determination. The transmitting station processes each link independently, determining carrier sensing timing based on individual transmission end times rather than managing all links as a single complex system. This segmentation reduces management complexity while maintaining the throughput benefits of multi-link operations.

The patent applies preliminary anti-action by proactively avoiding carrier sensing operations during the period when adjacent band interference is most severe. The system determines a timing window that excludes the immediate post-transmission period when interference occurs, and only performs carrier sensing outside this harmful period. This preliminary avoidance strategy prevents reception failures caused by adjacent band interference while still maintaining high channel utilization by performing sensing as soon as the interference period ends.
