Abstract
A method is disclosed for a wireless communication device (WCD) configured to receive, using a combiner selected from a plurality of combiners available at the WCD, downlink transmissions from a wireless communication node (WCN) via a downlink transmission beam selected from a plurality of downlink transmission beams available at the WCN. The method comprises, for each of the plurality of combiners, estimating an interference level experienced at the WCD. The method also comprises transmitting a measurement signal on each of a plurality of uplink transmission beams for selection of the downlink transmission beam by the WCN. Each of the plurality of uplink transmission beams corresponds to a respective one of the plurality of combiners available at the WCD. A signal strength of the measurement signal on an uplink transmission beam is responsive to the estimated interference level for the corresponding combiner. Corresponding arrangement, WCD and computer program product are also disclosed.
