CSI FEEDBACK FOR SINGLE DCI BASED MULTI-TRP TRANSMISSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18272170 titled 'CSI FEEDBACK FOR SINGLE DCI BASED MULTI-TRP TRANSMISSION

Simplified Explanation

The patent application describes systems and methods for Channel State Information (CSI) feedback in the context of Non-Coherent Joint Transmission (NC-JT) Physical Downlink Shared Channel (PDSCH) transmission from multiple Transmission/Reception Points (TRPs). Here are some key points to explain the innovation:

  • Method involves receiving a CSI reporting setting with specific resources for channel and interference measurement.
  • Interferences are measured based on CSI-IM resources, considering different instances of the same interference based on the set of receive antennas used.
  • CSI feedback is computed and reported, including NC-JT CSI, single TRP CSI, CRI, and second single TRP CSI.
      1. Potential Applications

- Wireless communication systems - 5G and beyond networks - Multi-antenna systems

      1. Problems Solved

- Efficient CSI feedback for NC-JT PDSCH transmission - Improved interference measurement and reporting - Enhanced communication reliability and performance

      1. Benefits

Original Abstract Submitted

Systems and methods for CSI feedback are provided. In some embodiments, a method performed by a UE for CSI feedback for Non-Coherent Joint Transmission (NC-JT) Physical Downlink Shared Channel (PDSCH) transmission from multiple Transmission/Reception Points (TRPs) includes: receiving a CSI reporting setting comprising: a set of NZP CSI-RS resources for channel measurement including a first and second NZP CSI-RS resource for channel measurement; and a set of CSI-IM resources including a first and second CSI-IM resource for interference measurement; measuring interferences based on the CSI-IM resources, where the interferences are considered different instances of a same interference if a same set of receive antennas are used, and the interferences are considered different interferences if different sets of receive antennas are used; and computing and reporting CSI feedback comprising: a NC-JT CSI and a first single TRP CSI; or a NC-JT CSI; or a CRI and a second single TRP CSI.
