WebOrthogonal frequency division multiple access (OFDMA) Wi-Fi 6 uses a combination of two modulation methods: orthogonal frequency division multiplexing (OFDM) and orthogonal frequency division multiple access (OFDMA). OFDMA is introduced in the 802.11ax standard for data transmissions. Block acknowledgement (BA) was initially defined in IEEE 802.11e as an optional scheme to improve the MAC efficiency. 802.11n amendment ratified in 2009 enhances this BA mechanism then made it as mandatory to support by all 802.11n-capable devices (formally known as HT - High Throughput devices). Instead of transmitting an individual ACK for every MPDU (i.e., frame), multiple MPDUs can be ac…
