Full Dimension Multiple Input Multiple Output Communication Systems and Methods

Abstract

Apparatuses and methods are disclosed for supporting a UE in reporting of a selection of an NZP CSI-RS resource to an eNB supporting FD-MIMO communication. Each NZP CSI-RS resource is associated with a unique NZP CRI (or ‘Beam Index’) on a given serving cell. The UE may select an NZP CSI-RS resource for CSI calculation and reporting to the eNB based on processed CSI-RS signals received at an antenna of the UE from the eNB of a serving cell of the UE based on a CSI-RS resource configuration for the UE signaled from the eNB. The UE may report a CRI and a CSI of the selected NZP CSI-RS resource to the eNB of the serving cell of the UE based on a CRI reporting configuration of the UE signaled from the eNB.

What is claimed is: 
     
         1 . One or more non-transitory, computer-readable media having instructions that, when executed by one or more processors, cause a user equipment (UE) to:
 process Channel State Information Reference Signal (CSI-RS) signals received at an antenna of the UE from an eNodeB (eNB), which supports Full Dimension Multiple Input Multiple Output (FD-MIMO) communication, of a serving cell of the UE based on a CSI-RS resource configuration for the UE signaled from the eNB in which two or more Non-Zero Power (NZP) CSI-RS resources are configured for the UE and in which each NZP CSI-RS resource is associated with a unique NZP CSI-RS Resource Indication (CRI) on a given serving cell;   select an NZP CSI-RS resource for channel state information (CSI) calculation and reporting to the eNB based on the processing of the received CSI-RS signals; and   report a CRI and a CSI of the selected NZP CSI-RS resource to the eNB of the serving cell of the UE based on a CRI reporting configuration of the UE signaled from the eNB.
