Solution Overview

Problem

The need for channelization designs of the 60 GHz band to support high data rate and low latency requirements for next-generation wireless local area networks (WLANs), particularly for metaverse applications like augmented and virtual reality, is not adequately addressed by existing IEEE 802.11 standards.

Innovation Solution

Proposed schemes for channelization of the 60 GHz band align with IEEE 802.11ad/ay channel allocations and reuse legacy IEEE 802.11ac/ax/be system designs, utilizing various channel spacing options and channel bandwidths, including 2.16 GHz, 1.08 GHz, and 0.72 GHz, with channel center frequencies defined as (channel starting frequency+ΔF)+ΔF*channelIndex, where ΔF is half of the channel spacing and channelIndex is the channel index value.
