Abstract: A method and apparatus for three-dimensional beamforming, which include an estimation of a channel spatial coherence for a beam space of a device based on a plurality of non-precoded reference signals such that the beam space includes a plurality of beam subspaces based on the estimated channel spatial coherence and each of the plurality of beam subspaces include a beam direction representative of a respective beam subspace of the plurality of beam subspaces. Furthermore, a selection a beam subspace of the plurality of beam subspaces based on a channel quality metric of the beam direction that is representative of the beam subspace is included.

Abstract: In various aspects, a Multiple-Input-Multiple-Output (MIMO) antenna array configuration, a wireless communication device, and a method for receiving multiple beamformed signals are described herein. According to at least one aspect, a MIMO antenna array configuration is described to include a plurality of Radio Frequency (RF) chains, a plurality of antenna elements, and a plurality of phase shifters. In some aspects, the antenna elements and phase shifters form a plurality of antenna arrays. The number of antenna arrays is, in at least one aspect, larger than the number of RF chains.
