IPC: H04W84/18
Filed: 2008-07-08
Abstract: Methods and apparatus for performing channel estimation and reporting back channel information or other information such as a suggested traffic transmission rate are described. A signal including a pilot signal of interest is received. Portions of the signal corresponding to the pilot signal are analyzed to determine if any of the portions, e.g., signal portions corresponding to individual tone symbols used to communicate the pilot signal, were subject to excessive interference, such as might be the result of collisions, rendering the signal portions unreliable. Signal sub-portions determined to be unreliable are excluded from a determination of the amount of pilot signal energy that was received. Signal interference is determined from a portion of the received signal on which the pilot signal was not transmitted. Channel information in the form of information and/or a suggested traffic rate may be reported back to the device which transmitted the pilot signal.
