Logic may determine phase correction information from pilot tones. Logic may determine phase correction information from some of the pilot locations. Logic may process the shifting pilot tones for less than all of the pilot tones. Logic may process pilot tones at any location within orthogonal frequency division multiplexing (OFDM) packet. Logic may determine to process only pilot tones at the even or odd symbol indices or subcarriers. And logic may transmit a packet with a frame with a capabilities information field comprising an indication that a receiver may can process shifting pilot tones for phase tracking.
