Patent ID: 8831125

Claim:
A method, in an eNodeB, for data transmission in a multiple antenna system, the eNodeB being comprised in a wireless communications network, the method comprising: receiving, from a user equipment, a plurality of signal quality assessments, wherein each signal quality assessment corresponds to a signal quality level for a distinct direction within at least one correlated domain of the multiple antenna system; receiving, from the user equipment, a Channel State Information, CSI, report measured on a reference signal that was beamformed into a distinct direction within the at least one correlated domain of the multiple antenna system; determining a beamforming direction for a data transmission to the user equipment based in-part on the plurality of signal quality assessments; estimating a quantity relating to a received power difference between a transmission beamformed as said CSI reference signal and a signal beamformed in said determined beamforming direction, based, at least in part, on said plurality of signal quality assessments; and accounting for the received power difference in the data transmission to the user equipment based on the estimating.
