摘要
Techniques for indicating active channel state information reference signal (CSI-RS) configurations for a user equipment (UE) are disclosed. The UE may be configured with multiple CSI-RS configurations and may receive signaling indicating which of its CSI-RS configurations are active. Improved performance may be obtained by dynamically signaling the active CSI-RS configurations. In one example, the UE may receive first signaling (e.g., upper-layer signaling) indicating a plurality of CSI-RS configurations configured for the UE. The UE may receive second signaling (e.g., lower-layer signaling) indicating at least one active CSI-RS configuration for the UE. The active CSI-RS configuration(s) may include all or a subset of the plurality of CSI-RS configurations. The UE may perform at least one communication task based on the at least one active CSI-RS configuration for the UE. The communication task(s) may include de-rate matching, CSI reporting, cell set management, etc.
