CROSS LINK INTERFERENCE BASED CHANNEL STATE INFORMATION REPORTING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17827540 titled 'CROSS LINK INTERFERENCE BASED CHANNEL STATE INFORMATION REPORTING

Simplified Explanation

The patent application describes methods, systems, and devices for wireless communications.

  • The user equipment (UE) can transmit channel state information (CSI) based on estimated cross link interference (CLI) at the UE.
  • A network entity can inform two UEs about transmission parameters of a multi-port CLI-reference signal (CLI-RS) that helps estimate the CLI channel between them.
  • The network entity can also inform the first UE about precoding parameters associated with uplink precoding at the second UE.
  • The second UE can transmit the multi-port CLI-RS to the first UE, and the network entity can transmit a CSI-reference signal (CSI-RS) to the first UE.
  • The first UE can then transmit a report that includes CSI based on the multi-port CLI-RS, the CSI-RS, and the precoding parameters.


Original Abstract Submitted

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit channel state information (CSI) that is based on an estimated cross link interference (CLI) at the UE. For example, a network entity may indicate, to a first UE and a second UE, transmission parameters of a multi-port CLI-reference signal (CLI-RS) that is associated with estimation of CLI channel between the first UE and the second UE. The network entity may indicate, to the first UE, one or more precoding parameters associated with uplink precoding at the second UE. The second UE may transmit the multi-port CLI-RS to the first UE, and the network entity may transmit a CSI-reference signal (CSI-RS) to the first UE. The first UE may transmit a report that includes CSI based on the multi-port CLI-RS, the CSI-RS, and the one or more precoding parameters.
