    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: A method for detecting a transmission from an interfering radio cell includes: receiving a signal comprising transmissions from a serving radio cell and from a plurality of interfering radio cells, wherein a reference symbol of a transmission from at least one interfering radio cell of the plurality of interfering radio cells is colliding with a reference symbol of a transmission from the serving radio cell; generating a set of transmission signal hypotheses, each of which is dependent on at least one interferer parameter of the at least one interfering radio cell; obtaining at least one interferer radio cell identifier; and detecting a transmission from at least one interfering radio cell of the plurality of interfering radio cells in the received signal based on the at least one interferer radio cell identifier and the set of transmission signal hypotheses.
