REDUCED CSI (CHANNEL STATE INFORMATION)-RS (REFERENCE SIGNAL) DENSITY SUPPORT FOR FD (FULL DIMENSIONAL)-MIMO (MULTIPLE INPUT MULTIPLE OUTPUT) SYSTEMS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240215060 titled 'REDUCED CSI (CHANNEL STATE INFORMATION)-RS (REFERENCE SIGNAL) DENSITY SUPPORT FOR FD (FULL DIMENSIONAL)-MIMO (MULTIPLE INPUT MULTIPLE OUTPUT) SYSTEMS

The techniques discussed in this patent application aim to facilitate reduced density of Channel State Information Reference Signals (CSI-RS). One example embodiment involves processing circuitry at a User Equipment (UE) that receives and processes a configuration message containing configuration parameters for CSI-RS Antenna Ports (APs) of a configurable density CSI-RS. The configuration parameters specify the density of CSI-RS resources per Physical Resource Block (PRB) per CSI-RS AP and a PRB offset. The processing circuitry then determines a set of Resource Elements (REs) for the CSI-RS APs based on the configuration parameters and performs measurements on the configurable density CSI-RS to determine CSI parameters.

  • Processing circuitry at a UE receives and processes a configuration message with parameters for CSI-RS APs.

  • The circuitry determines a set of REs for the CSI-RS APs based on the parameters.
  • Measurements are performed on the configurable density CSI-RS to determine CSI parameters.
  • Configuration parameters are provided per CSI-RS resource configuration.
    • Potential Applications:**

- Wireless communication systems - 5G networks - Mobile devices

    • Problems Solved:**

- Facilitates reduced density of CSI-RS - Efficient utilization of CSI-RS resources - Improved performance in wireless communication systems

Original Abstract Submitted

techniques discussed herein can facilitate reduced density csi (channel state information)-rs (reference signals). one example embodiment can be employed at a ue (user equipment) and can comprise processing circuitry configured to receive and process a configuration message that comprises one or more configuration parameters for one or more csi (channel state information)-rs (reference signal) aps (antenna ports) of a configurable density csi-rs. the configuration parameters indicate a density of csi-rs resource per physical resource block (prb) per csi-rs ap and a prb offset. the processing circuitry is further configured to determine a set of res (resource elements) for the one or more csi-rs aps of the configurable density csi-rs based on the one or more configuration parameters and perform measurements on the configurable density csi-rs from the set of res to determine one or more csi parameters. the one or more configuration parameters are provided per csi-rs resource configuration.
