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

This abstract first appeared for US patent application 17827503 titled 'REPORTING CONFIGURATION FOR CROSS LINK INTERFERENCE BASED CHANNEL STATE INFORMATION

Simplified Explanation

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

  • The invention involves a user equipment (UE) transmitting channel state information (CSI) based on a precoded cross link interference (CLI) channel at the UE.
  • A network entity can send a control message to a first UE, indicating a reporting configuration for CSI associated with a channel between the first UE and the network entity.
  • The first UE generates the CSI using a precoded CLI channel at the first UE, which is associated with at least one uplink transmission from a second UE.
  • The precoded CLI channel is generated using estimated CLI channels and candidate precoding matrices associated with the second UE.
  • The first UE then transmits the CSI to the network entity, following the reporting configuration.


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 a precoded cross link interference (CLI) channel at the UE. For example, a network entity may transmit a control message to a first UE that indicates a reporting configuration for indicating CSI associated with a channel between the first UE and the network entity. The first UE may generate the CSI based on a precoded CLI channel at the first UE associated with at least one uplink transmission associated with a second UE, where the precoded CLI channel is generated using at least one estimated CLI channel associated with the at least one uplink transmission and at least one candidate precoding matrix associated with the second UE. In accordance with the reporting configuration, the first UE may transmit the CSI to the network entity.
