Title:
ACCESS POINT (AP), STATION (STA) AND METHOD FOR SUBCARRIER SCALING
Document Type and Number:
WIPO Patent Application WO/2017/155649
Kind Code:
A3
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.
