Selecting beam-forming weighting vectors for antennae

摘要

A method, computer program and network node for selecting a beam-forming weighting vector is disclosed. The method comprises: receiving from user equipment a radio frequency fingerprint comprising indications of characteristics of radio signals received from the network node and at least one neighbouring network node within the wireless communication network. Accessing a data base associating a plurality of radio frequency fingerprints comprising the indications of characteristics of radio signals from the network node and from neighbouring network nodes with a plurality of beam-forming weighting vectors; and comparing the received radio frequency fingerprint with the radio frequency fingerprints within the data base and selecting one of the beam-forming weighting vectors in dependence upon the comparison.
