Method and Apparatus for Using a Determined Compression Matrix to Form a Set of Composite Beams

A wireless communication device comprising:

• a transceiver that receives a reference signal from a network entity, and communicates wirelessly with the network entity using a resulting new set of composite beams;
• and
• a controller that defines a default set of individual beams, each of the beams having an associated direction of extension;
• wherein the controller further determines a compression matrix, and applies the compression matrix to the default set of individual beams resulting in a new set of composite beams, as well as sends an indication of the determined compression matrix to the network entity, where at least one of the composite beams includes a combination of multiple individual beams from the default set, and where the multiple individual beams included in the at least one of the composite beams each extend in a different direction;
• and
• wherein a set of beam weighting values is determined and sent to the network entity.
