Measuring cross link interference
Methods, systems, and devices for wireless communications are described. The methods, systems, and devices may enable a base station to transmit a measurement configuration for measuring interference (e.g., cross link interference (CLI)). The measurement configuration may include a measurement direction configuration for measuring the interference. Additionally or alternatively, the UE may select a measurement direction configuration for measuring interference based on the measurement configuration. The UE may measure interference based on the measurement configuration. The UE may transmit a measurement report to the base station. The measurement report may include an indication of the selected measurement direction configuration.
