Abstract: 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.

Abstract: Embodiments of a high-efficiency Wi-Fi (HEW) device and method for HEW communicating are generally described herein. In some embodiments, an HEW frame is configured with a reduced signal field. The HEW frame may include a HEW signal field (HEW SIG-A1) which may include a single bit to indicate whether the HEW frame is a single user (SU) HEW frame or a multi-user (MU) HEW frame. A legacy signal field (L-SIG) is not included in the HEW frame. Rate information may be included in one or more signal fields that follow the HEW SIG-A1 and length information may be included in either the HEW SIG-A1 or the one or more signal fields that follow the HEW SIG-A1. The HEW frame may improve overall system efficiency, particularly in high-density deployment situations.

In some embodiments, the access point may be configured to operate as a master station and may configure an HEW frame to include a legacy signal field (L-SIG), an HEW signal field (HEW SIG-A) following the L-SIG, and one or more HEW fields following the HEW SIG-A. The L-SIG may be configured for transmission using a legacy number of data subcarriers, a legacy number of pilot subcarriers and a number of additional reference subcarriers modulated with a known reference sequence. At least one symbol of the HEW SIG-A and the one or more HEW fields following the HEW SIG-A of the HEW frame may be configured for transmission using additional data subcarriers. The additional data subcarriers may correspond to the additional reference subcarriers of the L-SIG.
