Abstract
Radio channel estimation in a radio node is provided. The radio node is configured to receive a number of wideband reference symbols corresponding to a wideband radio channel having a wideband bandwidth and convert the wideband reference symbols into a number of wideband taps each having a complex value and associated with a respective beam direction and a respective tap delay. The radio node dynamically determines a wideband power threshold based on channel information related to the wideband channel. Accordingly, the radio node determines a subset of the wideband taps based on the wideband power threshold and generates a channel estimate for the wideband radio channel based on the subset of wideband taps. As a result, the radio node may create a more accurate channel estimation across the wider channel bandwidth over a large span of SNR conditions.
