TID-Specific Buffer Status Reporting for Low-Latency Wireless Streams

The patent segments the buffer status reporting mechanism by introducing TID-specific triggering. Instead of a single general BSR mechanism, the system divides reporting into multiple TID-specific reports, allowing differential treatment of traffic streams. The BSRP-TID frame includes a TID bitmap field that identifies specific traffic streams, enabling the AP to request buffer status reports for individual TIDs rather than all traffic collectively.

The patent applies local quality by making buffer status reporting capability specific to each traffic identifier. Different TIDs can have different reporting behaviors based on their latency requirements. The BSR-TID control field includes per-TID queue size information, allowing the system to prioritize resources for latency-sensitive traffic (such as VR/AR streams) while using less stringent reporting for other traffic types.

The patent achieves universality by designing the BSRP-TID frame structure to handle multiple TIDs within a single frame format. The TID bitmap field can identify multiple traffic streams, and the BSR-TID control field can report buffer status for multiple TIDs simultaneously. This multi-functional approach allows the system to maintain precise TID identification while avoiding the overhead of separate reporting mechanisms for each TID.

The patent changes parameters within existing frame structures rather than creating entirely new complex structures. The BSRP-TID frame modifies the existing buffer status report poll format by adding a TID bitmap field and BSR-TID control field with per-TID parameters. This parameter-based approach enables precise traffic identification while maintaining compatibility with existing wireless communication protocols and minimizing structural complexity.

The patent merges multiple TID buffer status reports into a single aggregated report structure. The BSR-TID control field combines queue size information for multiple TIDs into one control field, and the TID bitmap identifies which TIDs are included in the report. This merging approach ensures comprehensive buffer status information is collected for all relevant TIDs while transmitting it in a consolidated manner, reducing the number of separate frames needed.

The patent applies partial action by triggering buffer status reports only for specific TIDs that need monitoring, rather than all TIDs unconditionally. The TID bitmap field allows selective identification of TIDs requiring buffer status reporting. This partial approach ensures complete information for prioritized traffic streams while avoiding unnecessary overhead for TIDs that do not require intensive monitoring, optimizing the balance between information completeness and communication efficiency.
