OFDMA is already deployed in 4G and 5G . In the world of wireless LAN, the latest Wi-Fi standard (IEEE 802.11ax) uses OFDMA for both uplink and downlink data transfer. The IEEE 802.11 standard defines the commonly used wireless LAN technologies, with 802.11ax recently being released into the marketplace.

Orthogonal Frequency Division Multiplexing (OFDM) is an efficient modulation format used in modern wireless communication systems including 5G.16 Nis 2020
Read moreDoes 5G use SC-FDMA?
Unlike LTE, 5G NR also supports CP-OFDM in the uplink direction. But LTE’s discrete Fourier transform spread OFDM (DFT-s-OFDM) uplink scheme, better known as single carrier frequency division multiplex (SC-FDMA), is still a valid access scheme and support is mandatory for any 5G terminal.

In comparison, 5G NR maximum carrier bandwidth is up to 100 MHz in frequency range 1 (FR1: 450 MHz to 6 GHz ), or up to 400 MHz in frequency range 2 (FR2: 24.25 GHz to 52.6 GHz) that can be aggregated with a maximum bandwidth of 800 MHz.

Frequency Range 1 (FR1) includes sub-6GHz frequency bands , some of which are bands traditionally used by previous standards, but has been extended to cover potential new spectrum offerings from 410 MHz to 7125 MHz.
