    摘要: Logic such as hardware and/or code to narrow available sub-channels in frequency selective transmission communications in which a station selects a narrow band from a wider channel bandwidth. A frequency selective transmission scheme for communications devices may select a 1 or 2 MHz channel from a wider channel bandwidth (e.g., 4, 8, 16 MHz) that consists of a number of 1 or 2 MHz sub-channels and transmitting packets on the selected sub-channel. The access point may narrow the number of sub-channels available for selection by stations. Stations may narrow the number of sub-channels. Both the AP and the stations may operate to narrow the number of sub-channels. A medium access control sub-layer protocol common to the communications devices may facilitate a frequency selective transmission scheme.

    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.

In some embodiments, an access point may select a value for the length field of a legacy signal field (L-SIG) that is non-divisible by three for communicating with HEW stations and may select a value for the length field that is divisible by three for communicating with legacy stations. In some embodiments, the access point may select a phase rotation for application to the BPSK modulation of at least one of the first and second symbols of a subsequent signal field to distinguish a high-throughput (HT) PPDU, a very-high throughput (VHT) PPDU and an HEW PPDU.
