Techniques to accommodate different classes of devices in a wireless network

摘要

An apparatus, a method and a machine-readable storage medium to accommodate both high function and low cost wireless devices in a wireless network. An exemplary apparatus includes a receiver to wirelessly receive a first packet comprising first and second shifting pilot signals amidst first data symbols transmitted via multiple subcarriers in symbol sets; a transmitter to wireless transmit a second packet; and logic to track a phase shift using the first and second shifting pilot signals, to configure the receiver to compensate for the shift in phase, to refrain from using reception of the first and second shifting pilot signals to update an initial channel estimate derived from a preamble of the first packet, and to transmit third and fourth shifting pilot signals amidst second data symbols of the second packet.

1. An apparatus comprising:
a receiver to wirelessly receive a first packet comprising a preamble comprising a known combination of symbols and a data portion comprising two shifting pilot signals among data symbols transmitted via multiple subcarriers in symbol sets; and logic to:
use reception of the known combination to detect characteristics of each subcarrier of the multiple subcarriers to derive an initial channel estimate;configure the receiver using the initial channel estimate to compensate for the detected characteristics;use the two shifting pilot signals to track a phase shift;configure the receiver to compensate for the shift in phase; andrefrain from using reception of the shifting pilot signals to update the initial channel estimate.
