Apparatuses and methods for CSI-RS configuration in distributed RRH systems

A method comprising:

• receiving, at a transmission point selection module (TPSM) of the wireless infrastructure component from a user equipment device (UE), a UE signal via one or more transmission points, wherein the one or more transmission points are in a plurality of transmission points sharing a single cell identification (ID), wherein each slot of a channel state information reference signal (CSI-RS) index in the UE signal corresponds to a single CSI-RS pattern and includes CSI-RS measurements derived from the single CSI-RS pattern, wherein each of the transmission points uniquely corresponds to a CSI-RS pattern;
• selecting a downlink transmission point from the transmission points based on the CSI-RS index in the UE signal;
• and
• configuring the UE to report CSI-RS measurements for the selected downlink transmission point by sending instructions to the UE to map CSI-RS patterns to slots in the CSI-RS index.

A non-transitory machine readable medium including instructions that, when executed by a machine, cause the machine to perform operations comprising:

• receiving, at a transmission point selection module (TPSM) from a user equipment device (UE), a UE signal via one or more transmission points, wherein the one or more transmission points are in a plurality of transmission points sharing a single cell identification (ID), wherein each slot of a channel state information reference signal (CSI-RS) index in the UE signal corresponds to a single CSI-RS pattern and includes CSI-RS measurements derived from the single CSI-RS pattern, wherein each of the transmission points uniquely corresponds to a CSI-RS pattern;
• selecting a downlink transmission point from the transmission points based on the CSI-RS index in the UE signal;
• and
• configuring the UE to report CSI-RS measurements for the selected downlink transmission point by sending instructions to the UE to map CSI-RS patterns to slots in the CSI-RS index.
