1. An apparatus for facilitating wireless communication, the apparatus comprising:

  • one or more memories; and

    one or more processors coupled to the one or more memories, the one or more processors configured to cause;

    determining a channel bandwidth among a plurality of bandwidths including a 20 megahertz (MHz) channel bandwidth, 40 MHz channel bandwidth, and 80 MHz channel bandwidth;

    determining a high efficiency long training field (HE-LTF) mode among a plurality of HE-LTF modes including a 4×

    HE-LTF mode and a 2×

    HE-LTF mode;

    generating an HE-LTF symbol by using an HE-LTF sequence corresponding to the determined channel bandwidth and the determined HE-LTF mode, wherein the HE-LTF sequence is among a plurality of HE-LTF sequences for the plurality of bandwidths and the plurality of HE-LTF modes; and

    transmitting a high efficiency physical layer protocol data unit (HE PPDU) including the HE-LTF symbol, in the determined channel bandwidth,wherein the plurality of HE-LTF sequences includes a first HE-LTF sequence for the 20 MHz channel bandwidth and the 4×

    HE-LTF mode, a second HE-LTF sequence for the 20 MHz channel bandwidth and the 2×

    HE-LTF mode, a third HE-LTF sequence for the 40 MHz channel bandwidth and the 4×

    HE-LTF mode, a fourth HE-LTF sequence for the 40 MHz channel bandwidth and the 2×

    HE-LTF mode, a fifth HE-LTF sequence for the 80 MHz channel bandwidth and the 4×

    HE-LTF mode, and a sixth HE-LTF sequence for the 80 MHz channel bandwidth and the 2×

    HE-LTF mode.
