Unified Signaling Scheme for EQM/UEQM in IEEE 802.11-24
This document presents a unified signaling mechanism for EQM and UEQM in IEEE 802.11-24, focusing on enhancing Beamforming Throughput. It covers proposed combinations, indicator options, and detailed patterns to enable more efficient communication. The aim is to streamline signaling processes for improved performance. The content emphasizes consensus-building and proposal evaluation within the context of wireless communications standards.

August 2024 doc.: IEEE 802.11-24/1431r0 A Unified Signaling Scheme for EQM/UEQM Date: 2024-08-21 Authors: Name Affiliation Address Phone Email Aiguo Yan aiguo.yan@samsung.com Zigui Yang 3655 N First St, San Jose, CA 95134 Srini Kandala Samsung Ravi Gidvani Eunsung Jeon Submission Slide 1 Aiguo Yan and et al, Samsung
August 2024 doc.: IEEE 802.11-24/1431r0 Introduction 1. The UEQMOD will be a key feature in 11bn to enhance BF ThroughPut. 2. A Motion on UEQMOD was already passed in July/2024 meeting. 3. There is a wide consensus on major combinations of UEQMOD. [4]-]7] 4. Many contributions proposed signaling details for UEQMOD (UEQM for short). [1],[3] 5. This contribution is proposing a unified signaling mechanism for both EQM and UEQM. Submission Slide 2 Aiguo Yan and et al, Samsung
August 2024 doc.: IEEE 802.11-24/1431r0 Proposed UEQM Combinations Recap Following 2 tables are cut and pasted from [5]. Similar info can also be found in [1]-[7], and many other contributions. [2] also proposed to add one more combination for 4SS case. No BaseMCS-2 twice Submission Slide 3 Aiguo Yan and et al, Samsung
August 2024 doc.: IEEE 802.11-24/1431r0 4 Options for a Unified Indicator Combine? EQM/UEQM N Y Y Y Y Combine? Patterns N Y Y Y Y Combine? Nss N N N Y Y Combine? BaseMCS N N N N Y Option 0 Option 1a Option 1b Option 3 Option 4 Reason for no details on Option 4 in this submission No consensus yet on total # of bits for the BaseMCS Details can be worked easily once having consensus. Don t want to make the table too complex. Any of Option 1a/1b/3 could be a good compromise. Submission Slide 4 Aiguo Yan and et al, Samsung
