Abstract: A device on a wireless network generates duration data for determining a duration of a time interval. A transmission is then instructed, by the device, to transmit the duration data and a downlink payload including an aggregated Media Access Control (MAC) layer data unit, the downlink payload being transmitted on first subcarriers. The transmission also includes a trigger that configures the at least one other device on the network to transmit an uplink payload within the time interval, and during at least part of the transmission of the downlink payload, on second subcarriers that are at different frequencies to the first subcarriers.
