METHOD AND APPARATUS FOR CSI REPORTING IN MULTI-TRP SCENARIOS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18305241 titled 'METHOD AND APPARATUS FOR CSI REPORTING IN MULTI-TRP SCENARIOS

Simplified Explanation

The patent application describes apparatuses and methods for reporting channel state information (CSI) in wireless networks with multiple transmission reception points (TRPs).

  • The method involves a user equipment (UE) receiving information about a CSI report, which includes NCSI reference signal (CSI-RS) resources.
  • The UE then measures the NCSI-RS resources and determines the CSI report associated with N≤NCSI-RS resources.
  • The CSI report includes a strongest coefficient indicator (SCI) for each layer, indicating the index of the strongest coefficient among K coefficients.
  • The method also involves transmitting the CSI report.

Bullet points:

  • Patent application for CSI reporting in multi-TRP operations in wireless networks.
  • User equipment (UE) receives information about a CSI report with NCSI-RS resources.
  • UE measures NCSI-RS resources and determines the CSI report associated with N≤NCSI-RS resources.
  • CSI report includes strongest coefficient indicator (SCI) for each layer.
  • SCI indicates index of strongest coefficient among K coefficients.
  • Method involves transmitting the CSI report.


Original Abstract Submitted

Apparatuses and methods for channel state information (CSI) reporting in multi-transmission reception point (TRP) operations in wireless networks. A method performed by a user equipment (UE) includes receiving information about a CSI report. The information indicates NCSI reference signal (CSI-RS) resources, where N>1. The method further includes, based on the information, measuring the NCSI-RS resources and determining the CSI report associated with N≤NCSI-RS resources, where N∈{1, 2, . . . , N}. The CSI report includes a strongest coefficient indicator (SCI) for each layer l (SCI). The SCIindicates an index of a strongest coefficient among Kcoefficients. l∈{1, . . . , ν} is a layer index, ν≥1 is a rank value, and Kis a total number of non-zero coefficients for a layer l associated with CSI-RS ports corresponding to the N CSI-RS resources. The method further includes transmitting the CSI report.
