Advanced Reuse and Amendment Framework for IMMW Systems
This document discusses a detailed reuse and amendment framework for the IMMW system under the IEEE 802.11-25/0xxxr0 standard. The focus is on enhancing efficiency and reducing system complexity by reusing sub-7GHz MAC/PHY components. The proposed approach emphasizes the importance of moderate beam searching procedures for indoor low mobility scenarios. Additionally, considerations for MAC design, initial link setup, and PHY aspects are outlined to optimize performance and facilitate the adoption of IMMW technology. The goal is to enable a flexible and advanced system architecture that leverages both existing standards and new innovations for improved wireless communication capabilities.

February 2025 Doc.: IEEE 802.11-25/0xxxr0 IMMW System Reuses Date: 2025-02-08 Authors: Name Affiliation Address Phone Email Yanchun Li Yunbo Li Ming Gan Fan Xu Yan Xin Maolin Zhang Xiang Wang Xin Li Xuming Wu Jian Li liyanchun@huawei.com Huawei Yanchun Li (Huawei) Submission Slide 1
February 2025 Doc.: IEEE 802.11-25/0xxxr0 Introduction IMMW PAR[1] defined the basic requirements and scope of the new mmW spec, which emphasizes the reuse and MLO framework: Use non-standalone operation in unlicensed bands in 42~71 GHz using SU OFDM based transmissions Expand the multi-link operation (MLO) defined in the sub-7.25 GHz band specifications to support non-standalone operation in the unlicensed bands between 42 GHz and 71 GHz. By reusing sub-7 GHz MAC/PHY, the system complexity and cost can be reduced. This contribution considers the tradeoff between reuse and efficiency. Moderate beam searching procedure is needed to support indoor low mobility use cases. Submission Slide 2 Yanchun Li (Huawei)

February 2025 Doc.: IEEE 802.11-25/0xxxr0 Summary This contribution discussed the detailed reuse and amendment under the scope of IMMW PAR. A flexible reuse framework allows IMMW system to be built on both 11be and 11bn. Such two-phase approach has benefit of promoting early adoption of IMMW/make use of 60GHz spectrum and also provide advanced performance. Submission Slide 5 Yanchun Li (Huawei)
