CHANNEL ESTIMATION FOR A SUBSET OF RESOURCE ELEMENTS OF A RESOURCE BLOCK

摘要

A technique for performing channel estimation for a wireless communication channel is provided. A determining unit (702, 704) determines delay spread (702) and/or Doppler spread (704) of the wireless communication channel (104). A channel estimation subunit (706) performs channel estimation at the positions of the received Reference Signals, and a filtering subunit (708) performs filtering of the channel estimates for estimating channel coefficients for a subset of Resource Elements transmitted on the wireless communication channel. The subset is chosen (710) depending on the determined delay spread (702) and/or Doppler spread (704). An interpolating unit (130) interpolates the estimated coefficients for Resource Elements that are not included in the subset.
