Isochronous Channel Configuration for HID Data Transmission

The patent dynamically selects between ACL and ISO channels based on data characteristics (reliability requirements and urgency). For time-sensitive data requiring high speed, ISO channels provide dedicated bandwidth. For non-time-critical data, ACL channels reduce energy consumption. This dynamic adaptation resolves the contradiction between speed and energy efficiency.

The patent applies different channel qualities to different data types. Time-sensitive data (e.g., gaming input, AR/VR synchronization) is transmitted through ISO channels with guaranteed bandwidth and timing. Non-time-critical data uses ACL channels for energy efficiency. This local differentiation of transmission quality resolves the contradiction between energy consumption and reliability for specific data types.

The patent adjusts ISO channel parameters (burst number, sub-events) based on data characteristics. For high-speed requirements, it increases burst number and configures appropriate sub-events. The system automatically optimizes these parameters based on traffic patterns, reducing manual configuration complexity while maintaining high transmission speeds when needed.

The patent implements dynamic retransmission strategies where the number of retransmission attempts and timing are adjusted based on data characteristics. For critical data, limited retransmissions are permitted within strict time windows. For non-critical data, retransmissions are minimized or eliminated. This dynamic approach resolves the contradiction between reliability and latency by applying retransmission only where necessary and within acceptable time constraints.
