METHODS AND ARRANGEMENTS TO DETERMINE STATION ASSIGNMENTS TO RESTRICTED ACCESS WINDOWS IN WIRELESS NETWORKS

摘要

Logic may reduce overhead in communications that include pilot tones in symbols by establishing a predefined pattern of subcarriers on which the pilot tones are transmitted and including the pilot tones in L out of every N symbols in the communications. Logic may implement communications in accordance with the predefined pattern of subcarriers by inserting N minus L symbols between symbols with pilot tones on each of the subcarriers of the predefined pattern of subcarriers or by inserting tones other than pilot tones on pilot subcarriers in N minus L out of every N symbols. Logic may determine channel state information along with carrier frequency and phase tracking information from pilot tones in the symbols. And logic may determine channel state information for symbols that do not include pilot tones by calculating channel estimates based upon channel estimates of adjacent subcarriers and/or by previous channel estimates of the pilot subcarriers.
