Antenna port multiplexing

Abstract:

Embodiments can provide an apparatus for a User Equipment (UE) for processing a Channel State Information Reference signal (CSI-RS) associated with a prescribed CSI-RS resource configuration, comprising CSI-RS resources, relating to a predetermined plurality of antenna ports; the apparatus comprising circuitry to: process data associated with the prescribed CSI-RS resource configuration relating to the predetermined plurality of antenna ports, said CSI-RS resource configuration comprising multiplexing data to provide an indication of the multiplexing of the CSI-RS signal over the CSI-RS resources; process data associated with a CSI-RS signal conveyed using the CSI-RS resources according to the CSI-RS resource configuration to support a channel estimation using the data associated with the CSI-RS signal.
