Abstract: Embodiments of a User Equipment (UE) and methods for communication using beam aggregation are generally described herein. The UE may receive first and second directional signals from a first eNB and a second eNB as part of a beam aggregation. The UE may transmit one or more channel state information (CSI) messages to the eNBs. The CSI messages may include rank indicators (RI) for the first and second signals. The RIs may indicate numbers of directional beams between the eNBs and the UE that are determined as part of the reception of the first signal. In some cases, when multiple transmit beams are included in a directional signal, the CSI messages may include multiple RIs for each of the transmitted beams.

Abstract: Technology is discussed for supporting wireless communication paths from an antenna array with a vertical directional component. Examples reduce training feedback for increased numbers of communication paths by only reporting on a subset of Reference Signals (RSs) provided for various vertical beam configurations. Additional examples reduce feedback with virtual measurements based on a difference between RS measurements. One such measurement can come from full set of RSs for a reference beam configuration and another from a partial set of RSs for an additional beam configuration. Such virtual measurements can also be based on cross correlation for beamforming weights associated with the two configurations. Several examples of preparing and sending measurement reports consistent with Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards are discussed. The supporting technology also increases diversity and reduces a power differential between spatially multiplexed layers transmitting a common codeword.
