Air Interface Latency Target (<0.1 ms)

Technical Explanation

To synchronize microsecond-level industrial robotics, closed-loop power systems, and tactile sensations, 6G cuts the air interface one-way latency from 5G's 1 ms down to less than 0.1 ms (100 microseconds). This is realized through extreme sub-carrier spacings (960 kHz and above), ultra-short mini-slot symbol durations, non-orthogonal multiple access, and immediate grant-free pre-allocated transmission slots.

Key Functions

• Caps one-way air transmission delay strictly below 100 microseconds
• Reduces physical symbol transmission duration via expanded numerology
• Enables instantaneous closed-loop industrial automation and feedback
• Achieves 10x lower latency than commercial 5G URLLC
