A STA to detect a HE SIG may be configured to detect the HE SIG based on at least one from the following group: a flipped reserved bit, a scrambled portion of the HE SIG, and a rotation of a signal constellation of the HE SIG different than legacy rotations of: a rotation of a first signal constellation and no rotation of a second signal constellation, and no rotation of the first signal constellation and a rotation of the second signal constellation. The STA may determine that a reserved bit is the flipped reserved bit based on a bit being reversed from a legacy standard. The STA may unscramble a received signal field, determine whether a CRC indicates the HE-SIG contains errors, and if the CRC indicates there are no errors, then determine that the signal field is the HE SIG."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus, method, and computer readable medium for high-efficiency wireless local-area network (HEW) signal field detection","description":"Apparatuses, methods, and computer readable media are disclosed.
