  • REPORTING CONFIGURATION FOR CROSS LINK INTERFERENCE BASED CHANNEL STATE INFORMATION
    Publication number: 20230387989
    Abstract: 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.
