ABSTRACT:
The invention is related to a communication terminal, including means for determining possible antenna weight factor combinations, an antenna weight factor combination comprising an antenna weight factor for both power and phase; means for selecting primary antenna weight factors on the basis of bisectors of angles between a minimum phase offset and a maximum phase offset of the possible weight factor combinations; means for determining an optimum antenna weight factor by using the primary antenna weight factors; and means for signalling the optimum antenna weight factor to a network element.
