Abstract: Fractional symbol based phase noise mitigation, including methods and systems to determine phase noise trajectory, or indication of phase noise, for each of multiple fractional portions of a frequency domain symbol, and modify the symbol based on the phase noise trajectories of the subsets. Multiple correction hypotheses may be generated for each fractional portion of the symbol based on pre-defined phase noise hypotheses. The correction hypotheses may include frequency domain correction hypotheses. The correction hypotheses for a subset may be evaluated to select one of the phase noise hypotheses as the trajectory for the subset. The evaluation may include applying each correction hypothesis to a corresponding equalized frequency domain symbol to generate corresponding symbol hypotheses, computing a signal quality for each symbol hypothesis, and comparing the signal qualities. Signal qualities may be determined as error vector magnitudes, and may be based on all or a subset of corresponding symbol tones.

Abstract: Embodiments of an access point (AP), station (STA) and method for subcarrier scaling are generally described herein. The AP may transmit a high efficiency (HE) physical layer convergence procedure (PLCP) protocol data unit (PPDU) that includes a legacy long training field (L-LTF), a legacy signal (L-SIG) field, and an HE signal (HE-SIG) field. The HE-SIG may be based on HE-SIG symbols mapped to a group of HE subcarriers that includes legacy subcarriers and HE extension subcarriers. The L-LTF may be based on L-LTF pilot symbols mapped to the legacy subcarriers. The L-SIG may be based on L-SIG legacy symbols mapped to the legacy subcarriers and L-SIG extension pilot symbols mapped to the HE extension subcarriers. The AP may scale a per-subcarrier power of the L-SIG extension pilot symbols to match a per-subcarrier power of the L-LTF pilot symbols.
