Abstract

See full text

A first communication device receives a plurality of training signal fields in a preamble of a data unit transmitted by a second communication device, the plurality of training signal fields in orthogonal frequency division multiplexing (OFDM) symbols comprising data and pilot tones. The first communication device determines first channel estimate data corresponding to the data tones in the OFDM symbols, and uses pilot tones in the plurality of training signal fields to track at least one of i) a phase offset and ii) a frequency offset while receiving the plurality of training signal fields to improve the first channel estimate data. The first communication device generates feedback data that i) includes data corresponding to the first channel estimate data, and ii) excludes data corresponding to second channel estimate data for the pilot tones in the plurality of training signal fields, and transmits the feedback data to the second communication device.
