In order to prevent undesirably large peak-to-average power ratio (PAPR) transmissions caused by repeated information in the HE SIG-B field, the HE SIG-B field may be scrambled. Scrambling of the HE SIG-B field may include scrambling of modulated data tones of each of one or more HE SIG-B field channels of the HE SIG-B field. This scrambling may include applying a phase rotation to the modulated data tones within each of the one or more HE SIG-B field channels. This scrambling (or phase rotation) is performed in addition to a phase rotation applied to each entire HE SIG-B field channel that is commonly referred to as a gamma rotation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for scrambling control field information for wireless communications","description":"In wireless communications, a high-efficiency (HE) physical layer protocol data unit (PPDU) includes an HE signal-B (SIG-B) field.
