Candidate features

The main candidate features mentioned in the 802.11be Project Authorization Request (PAR) are:[5]

• 320 MHz bandwidth and more efficient utilization of non-contiguous spectrum,
• Multi-band/multi-channel aggregation and operation,
• 16 spatial streams and Multiple Input Multiple Output (MIMO) protocols enhancements,
• Multi-Access Point (AP) Coordination (e.g. coordinated and joint transmission),
• Enhanced link adaptation and retransmission protocol (e.g. Hybrid Automatic Repeat Request (HARQ)),
• If needed, adaptation to regulatory rules specific to 6 GHz spectrum,
• Integrating Time-Sensitive Networking (TSN) IEEE 802.1Q extensions for low-latency real-time traffic: [6][7]
  • IEEE 802.1AS timing and synchronisation
  • IEEE 802.11aa MAC Enhancements for Robust Audio Video Streaming (Stream Reservation Protocol over IEEE 802.11)
  • IEEE 802.11ak Enhancements for Transit Links Within Bridged Networks (802.11 links in 802.1Q networks)
  • Bounded latency: credit-based (IEEE 802.1Qav) and cyclic/time-aware traffic shaping (IEEE 802.1Qch/Qbv), asynchronous traffic scheduling (IEEE 802.1Qcr-2020)
  • IEEE 802.11ax Scheduled Operation extensions for reduced jitter/latency

Additional features

Apart from the features mentioned in the PAR, there are newly introduced features:[8]

• Newly introduced 4096-QAM (4K-QAM),
• Contiguous and non-contiguous 320/160+160 MHz and 240/160+80 MHz bandwidth,
• Frame formats with improved forward-compatibility,
• Enhanced resource allocation in OFDMA,
• Optimized channel sounding that requires less airtime,
• Implicit channel sounding,
• More flexible preamble puncturing scheme,
• Support of direct links, managed by an access point.
