Tactile Packet Priority Pre-Emptor

Sub-Microsecond Radio Physical Layer Preemption for Critical Touch Packets

Hardware mechanism that instantly halts non-critical video or file downloads mid-symbol to inject urgent surgical or safety touch packets.

Technical Explanation

In 6G shared channels, a base station may be halfway through transmitting a massive 4K video transport block when an urgent robotic surgical feedback or vehicle collision alert arrives. Waiting for the video transmission to finish would violate the sub-0.1 ms latency deadline. The Tactile Packet Priority Pre-Emptor punctures and halts the background transmission mid-symbol, immediately injecting the critical tactile packet into the air interface with zero queuing delay.

Key Functions

  • Punctures ongoing non-urgent transmissions mid-symbol to transmit critical touch data
  • Guarantees sub-100 microsecond air latency for life-critical haptic and safety feedback
  • Restores and retransmits punctured background video packets using low-overhead parity
  • Enforces strict mission-critical priority across mixed-traffic 6G carriers
