Background

IEEE 802.11 has approved the creation of a new task group to work on a major amendment, IEEE 802.11bn, for next generation wireless LAN, that applies to carrier frequency operation between 1 GHz and 7.250 GHz.

This amendment defines modifications to both the IEEE Std 802.11 physical layer (PHY) and the IEEE Std 802.11 Medium Access Control (MAC). The amendment adds an Ultra High Reliability capability to a Wireless Local Area Network (WLAN). The Ultra High Reliability capability is defined for both an isolated Basic Service Set (BSS) and overlapping BSSs as:

         At least one mode of operation capable of increasing throughput by 25%, as measured at the MAC data service Access Point, in at least one Signal to Interference and Noise Ratio (SINR) level (Rate-vs Range), compared to the Extremely High Throughput MAC/PHY operation, and

         At least one mode of operation capable of reducing latency by 25% for the 95th percentile of the latency distribution compared to the Extremely High Throughput MAC/PHY operation and

         At least one mode of operation capable of reducing MAC Protocol Data Unit (MPDU) loss by 25% compared to the Extremely High Throughput MAC/PHY operation for a given scenario, especially for transitions between BSSs.

This amendment provides a mechanism to reduce power consumption for Access Points (APs) (including mobile APs) and improved Peer-to-Peer (P2P) operation compared to the Extremely High Throughput MAC/PHY operation.

This amendment shall ensure backward compatibility and coexistence with legacy IEEE 802.11 devices in the 2.4 GHz, 5 GHz, and 6 GHz unlicensed bands.

March 2024 Denver, Colorado, USA

TGbn had scheduled 7 sessions during the March plenary. The group discussed more than 45 technical submissions, covering a wide range of topics, including but not limited to: Multi AP coordination, relay operation, pilots, LDPC, sounding, Aggregated (A-) PPDU, coexistence, distributed resource unit (RU), non-primary channel access, dynamic secondary operation, channel access, power save, roaming, feedback reports, preamble, modulation, coordinated beamforming, etc. The group reached general consensus on a couple of power save mechanisms and adding additional details to the design of distributed RUs.

January 2024 Panama City, Panama

TGbn had scheduled 9 sessions during the January interim. The group elected three vice-chairs for each of the two ad-hoc groups (PHY and MAC). In addition, the group discussed more than 50 technical submissions, covering a wide range of topics, such as distributed resource units (RUs), quality of service (QoS), power save, multi input multi output (MIMO), preamble design, coordinated beamforming (CBF), roaming, unequal modulation (UEM), coordinated R-TWT, coordinated spatial reuse, etc. The group reached general consensus on distributed RU and roaming.

November 2023 Honolulu, Hawaii

TGbn had scheduled 5 sessions during the November plenary. The group approved several task group documents (selection procedure, timeline, functional requirements), appointed the secretary and the technical editor, elected three vice-chairs, and approved the creation of two ad-hoc groups (PHY and MAC), each with 3 ad-hoc chairs. In addition, the group discussed 15 technical submissions, covering a wide range of topics, such as power save, relay, security, roaming, multi-AP, secondary channel access, peer to peer, and preemption.
