Abstract

A mobile communication device is described comprising a receiver configured to receive, for each of a plurality of transmit beam directions, a reference signal transmitted based on the transmit beam direction, wherein each transmit beam direction has at least one allowable precoder, a determiner configured to determine, for each transmit beam direction, a reception quality of the reference signal transmitted based on the transmit beam direction, a preselector configured to preselect, from the plurality of transmit beam directions, a subset of transmit beam directions based on a comparison of the determined reception qualities, an evaluator configured to determine, for each transmit beam direction of the subset, an evaluation of the performance of the allowable precoders of the transmit beam direction, a selector configured to select, from the subset, a beam direction for communication, based on the evaluations and a controller configured to establish communications based on the selected beam direction.
