4G and 5G use OFDM with a cyclic prefix. Will 6G do the same? This applies to downlink (basestation to handset). If CP-OFDM is one of multiple supported modulation schemes, this question resolves YES. Closes when corresponding 3GPP spec is published, expected in rel19 end 2025.

• Update 2026-01-01 (PST) (AI summary of creator comment): The market close date has been extended as there is no normative 6G standard published yet. The creator will continue monitoring 3GPP meeting notes for updates on whether CP-OFDM will be included in the 6G specification.
