Methods, apparatuses, and computer readable media are disclosed to signal a packet configuration. A HEW device to signal a packet configuration may include circuitry. The circuitry may be configured to generate a HE packet comprising a legacy signal field (L-SIG) followed by one or more HE signal fields and include in the L-SIG the packet configuration of the HE packet to signal to a second HEW device. The circuitry may configure a length field of the L-SIG to be a one or two modulo of three (MOD 3) to indicate the HE packet. The length field of the L-SIG may indicate that the HE packet includes a portion that has a one-quarter size subcarrier. The circuitry may set the length field of the L-SIG to be 1 mod 3 to indicate a first type of HE packet and to be 2 mod 3 to indicate a second type of HE packet.
