Claim Text:
1. A method, in an eNodeB, for establishing beamforming for a multiple antenna system, the eNodeB being comprised in a wireless communications network, the method comprising: transmitting, to a user equipment, a plurality of reference signals, each reference signal being beamformed into a distinct direction within at least one correlated domain of the multiple antenna system; determining a position of the user equipment relative to the eNodeB; configuring the user equipment to perform signal quality assessments on a subset of the plurality of reference signals based at least in part on the determined position of the user equipment relative to the eNodeB; receiving, from the user equipment, signal quality assessments for each of the subset of the plurality of reference signals; and generating downlink communication signals for antenna elements and/or sub-elements of the multiple antenna system, the downlink communication signals being beamformed in a transmitting direction in the at least one correlated domain, said transmitting direction being determined, in-part, from the received signal quality assessments; wherein:
