Abstract: A method of transmitting a frame is provided by a device in a WLAN. The device sets as additional data subcarriers some of subcarriers which are not set as data subcarriers in at least part of fields included in a frame of a legacy frame format, and allocates information to the additional data subcarriers.

Abstract: An apparatus is provided. The apparatus performs operations including selecting a high efficiency long training field (HE LTF) sequence for a frame, selecting an HE LTF transmission mode from one of a 4×HE LTF mode, a 2×HE LTF mode, and a 1×HE LTF mode, transmitting only a set of allocated subcarriers of the HE LTF sequence for the frame, and transmitting a set of additional fields of the frame using the set of allocated subcarriers and a set of unallocated subcarriers. The set of additional fields includes a legacy short training field (L-STF), a legacy long training field (L-LTF), a legacy signaling field (L-SIG), a high efficiency signaling A field (HE-SIG-A), and a high efficiency short training field (HE-STF). Transmitting of the HE LTF sequence for the frame uses only one or more of the set of allocated subcarriers, and none of the unallocated subcarriers.
