METHOD, APPARATUS, AND COMPUTER READABLE MEDIUM FOR SIGNALING HIGH EFFICIENCY PACKET FORMATS USING A LEGACY PORTION OF THE PREAMBLE IN WIRELESS LOCAL-AREA NETWORKS
First Claim
1. An apparatus of a high-efficiency (HE) wireless local area network (HEW) device, comprising circuitry configured to:
- generate a HE packet comprising a legacy signal field (L-SIG) followed by one or more HE signal fields, wherein the one or more HE signal fields comprises a HE-SIG-A field, and wherein a modulation and coding scheme (MCS) sub-field of the HE-SIG-A field jointly signals a MCS and one or more other sub-fields; and
transmit the HE packet to one or more HEW devices.

Abstract
A high-efficiency (HE) wireless local area network (HEW) device including circuitry is disclosed. The circuitry may be configured generate a HE packet comprising a legacy signal field (L-SIG) followed by one or more HE signal fields, where the one or more HE signal fields include a HE-SIG-A field, and where a modulation and coding scheme (MCS) sub-field of the HE-SIG-A field jointly signals a MCS and one or more other sub-fields. The one or more other sub-fields may be a low-density parity check (LDPC) or a space-time block coding (STBC).The circuitry may be configured to generate the L-SIG to signal to the one or more HEW devices either a first packet format of the HE packet or a second packet format of the HE packet, where a length of the L-SIG modulo 3 is used to signal the first packet format or the second packet format.
