ENHANCED CHANNEL STATE FEEDBACK REPORTING - A simplified explanation of the abstract

This abstract first appeared for US patent application 17827502 titled 'ENHANCED CHANNEL STATE FEEDBACK REPORTING

Simplified Explanation

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

  • The invention focuses on a user equipment (UE) transmitting channel state information (CSI) based on estimated cross link interference (CLI) at the UE.
  • A network node can send a control message to a first UE, indicating candidate precoding matrices associated with uplink precoding at a second UE.
  • The first UE receives a CSI-reference signal (CSI-RS) for estimating the channel between the first UE and the network node, as well as a CLI-reference signal (CLI-RS) for estimating the CLI channel between the first UE and the second UE.
  • The bandwidth of the CLI-RS is determined by a measurement rule.
  • The first UE generates CSI using the CSI-RS, the CLI channel, and one or more of the candidate precoding matrices.
  • The first UE then transmits a CSI report, including the CSI, to the network node.


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 node may transmit a control message to a first UE that indicates one or more candidate precoding matrices associated with uplink precoding at a second UE. The first UE may receive a CSI-reference signal (CSI-RS) associated with estimation of a channel between the first UE and the network node and may receive a CLI-reference signal (CLI-RS) associated with estimation of a CLI channel between the first UE and the second UE. The bandwidth of the CLI-RS may be based on a measurement rule. The first UE may generate CSI based on the CSI-RS, the CLI channel, and one or more of the candidate precoding matrices and transmit a CSI report including the CSI.
