Abstract

See full text

In an example of wireless communications based on orthogonal frequency-division multiple access (OFDMA), an access point may send a downlink frame to multiple stations. In response, some or all of the stations may transmit their respective uplink frames simultaneously after a predetermined time period. The uplink frames from the stations may be aggregated or multiplexed to form a final uplink frame that is received by the access point. Each of the uplink frames from the stations may include at least a legacy header and an acknowledgment frame. While a legacy header occupies the entire channel bandwidth of its uplink frame, an acknowledgment frame occupies a sub-band assigned to its station, where a sub-band is a portion of the channel bandwidth. Other methods, apparatus, and computer-readable media are also disclosed.
