Claim:
1. A method of transmitting a frame by a device in a wireless local area network (WLAN), the method comprising: generating a legacy short training field; generating a legacy long training field immediately following the legacy short training field; generating a legacy signal field immediately following the legacy long training field; generating a BPSK-modulated signal field including one orthogonal frequency division multiplexing (OFDM) symbol immediately following the legacy signal field, wherein the one OFDM symbol of the BPSK-modulated signal field includes a plurality of information bits, a first part of the plurality of information bits corresponds to a mode field indicating whether a mode of a frame is a High Efficiency (HE) mode of the WLAN, and a second part of the plurality of information bits corresponds to tail bits; and transmitting the frame including the legacy signal field, the legacy short training field, the legacy long training field, and the BPSK-modulated signal field.
