Methods, apparatuses, and computer-readable media for a wireless communication device for transmitting pilots in a wireless local area network are disclosed. The method on a wireless communication device includes receiving one or more packets in a transmit opportunity (TXOP), wherein the one or more packets indicate a schedule for the wireless communications device to transmit. The method further includes transmitting a first pilot carrier in a lower subcarrier of a frequency allocation, and transmitting a second pilot carrier in a higher subcarrier of the frequency allocation. The first pilot and the second pilot may be transmitted simultaneously or in alternative time periods. The lower subcarrier may be the lower one-third of the frequency allocation, and the higher subcarrier may be the higher one-third of the frequency allocation. The wireless communication device may transmit and receive in accordance with OFDMA and 802.11.
