Abstract
The aim of the invention is to estimate a dedicated channel of the downlink transmission from a base station (BS) to a subscriber station (MS) in a mobile radio communications system with antenna diversity. To this end the subscriber station (MS) calculates a first estimation of the dedicated channel from an estimation of a global channel (CPICH) while using a weighting vector (W W) used by the base station (BS) for the beam forming of the dedicated channel.
