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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus, and computer readable medium for signaling high efficiency packet formats using a legacy portion of the preamble in wireless local-area networks","description":"A high-efficiency (HE) wireless local area network (HEW) device including circuitry is disclosed.
