摘要： Embodiments of an access point and method for high-efficiency WLAN (HEW) communication are generally described herein. In some embodiments, the access point may be configured to operate as a master station and may configure an HEW frame to include a legacy signal field (L-SIG), an HEW signal field (HEW SIG-A) following the L-SIG, and one or more HEW fields following the HEW SIG-A. The L-SIG may be configured for transmission using a legacy number of data subcarriers, a legacy number of pilot subcarriers and a number of additional reference subcarriers modulated with a known reference sequence. At least one symbol of the HEW SIG-A and the one or more HEW fields following the HEW SIG-A of the HEW frame may be configured for transmission using additional data subcarriers. The additional data subcarriers may correspond to the additional reference subcarriers of the L-SIG.

摘要： A system and method are provided for implementing improved frequency estimation for wireless communication that involves lower power transmissions with reduced signal-to-noise ratios for receivers particularly in systems configured according to the pending IEEE 802.11ah standard. These systems and methods provide frequency estimation over that prescribed for devices operating according other IEEE 802.11 standards and the proposed frequency estimator specified for IEEE 802.11ac systems. The disclosed techniques use schemes that reuse a short training field (STF) stored in memory, employ joint STF-long training field (LTF) estimation, use portions of a guard interval (GI), and create of multiple-phase estimates, with different symbol separation to improve a signal-to-noise ratio of the frequency estimate.
